Description

The present invention relates to the field of communication, and more particularly to communication methods, terminal devices and network devices.

In 5th generation communication (5G) technology, the demand for low communication latency and high reliability is increasing. Currently, in order to reduce the delay, the transmission delay interval (TTI: Transition Time Interval) (Shortened TTI) technology is mainly adopted, that is, the current frame structure is modified to reduce the subframe interval. Accelerates signaling feedback and scheduling cycles, reduces system loopback delays, and accelerates the rhythm of data transmission and reception. The subframe interval in current LTE systems is 1 ms (including 14 Orthogonal Frequency Division Multiplexing (OFDM) symbols), and in Shortened TTI technology, subframes are 0.2-0.5 ms. We are trying to shorten it to (including 3-7 OFDM symbols). Even if the Shortened TTI is adopted and the subframe interval is shortened from 1 ms to 0.2-0.5 ms, the delay is still long only by shortening the above scheduling cycle to around 2-4 ms.

Each antenna set can include one or more antennas, for example one antenna set can include antennas 104 and 106 and another antenna set can include antennas 108 and 110. And the additional set can include antennas 112 and 114. Although FIG. 1 shows two antennas for each antenna set, each set can use more or less antennas. The network device 102 can additionally include a transmitter chain and a receiver chain, all of which can be described by those skilled in the art as having multiple components for transmitting and receiving signals (eg, processors, modulators, multiplexers, demodulators, etc.). It can be understood that it can include demultiplexers or antennas).

The network device 102 can communicate with a plurality of terminal devices (eg, terminal device 116 and terminal device 122). Further, it is possible to understand that the network device 102 can communicate with any number of terminal devices similar to the terminal device 116 or 122.

FIG. 2 is a schematic flowchart of the communication method 200 according to the embodiment of the present invention. As shown in FIG. 2, the method 200 includes 201 to 210.

In 201, the network device can transmit data resource pool configuration information to the terminal device, and the data resource pool configuration information is used to indicate a resource included in the data resource pool, and the data resource pool is used. The resources included in are resources that can be selected by the terminal device for transmitting the transmission version of the uplink data.

In 202, the network device can send control resource pool configuration information to the terminal device, and the control resource pool configuration information is used to indicate resources included in the control resource pool and is included in the control resource pool. The resource is a resource that can be selected by the terminal device for transmitting a scheduling configuration (SA) message.

As an option, the network device can use system information (SI: System Information) to transmit control resource pool configuration information and data resource pool configuration information to the terminal device.

Optionally, in an embodiment of the invention, the network device does not send a data resource pool configuration message and / or a control resource pool configuration message to the terminal device, but instead sends the data resource pool configuration message and / or control resource to the terminal device. Pool configuration messages can be set statically.

Optionally, in the embodiments of the invention, the resources of the resource pool are defined by at least two dimensions, a time domain and a frequency domain, or further include dimensions such as a code domain and / or a spatial domain.

At 203, the terminal device can determine the data transmission format for acquiring the transmission version of the uplink data.

Optionally, in an embodiment of the invention, the data transmission format can include modulation and coding schemes (MCS), coded version information, and the like.

At 204, the terminal device can determine the data transmission resource that carries the transmission version of the uplink data.

At 205, the terminal device can generate a scheduling configuration message, which includes information on the data transmission format determined in 203 and information on the data transmission resource determined in 204.

At 206, the terminal device can select a resource to send the scheduling configuration message from the control resource pool and send the scheduling configuration message to the network device.

Alternatively, in the embodiments of the present invention, the network device does not send control resource pool configuration information to the terminal device, but the terminal device directly utilizes the transmission resource set by the network device to indicate the scheduling configuration message. Transmission resources can be set directly for the terminal device scheduling configuration message to transmit, where the network device does not superimpose each other on the terminal device by system information for the scheduling configuration message. Resources can be set.

For example, as shown in FIG. 3, the base station can transmit a system message, which is used to indicate a data transmission resource pool and a control transmission resource pool. The data transmission resource pool is used to transmit the transmission version of the uplink data, and the control transmission resource pool is used to indicate the data transmission resource of the uplink data transmission version and the data transmission format. Alternatively, the base station may send a system message, which indicates a data resource pool and a resource to which the scheduling configuration message is sent.

At 207, the terminal device encodes and modulates the uplink data based on the data transmission format determined in 203 to generate a transmission version of the uplink data.

At 208, the terminal device uses the data transmission resource determined at 204 to transmit the transmission version of the uplink data.

At 209, the network device receives the transmission version of the uplink data transmitted by the terminal device in the data transmission resource indicated by the scheduling configuration message transmitted by the terminal device.

At 210, the network device uses the data transmission format indicated by the scheduling configuration message transmitted from the terminal device to demodulate and decode the transmission version of the uplink data.

In an embodiment of the invention, if the network device successfully demolishes and decodes the transmitted version of the uplink data, it can send an acknowledgment (ACK) message to the terminal device, or the network device will uplink.

At 308, the terminal device transmits N transmission versions of the uplink data by the N data transmission resources determined in 304, where N transmission resources and N transmission versions. There is a one-to-one correspondence with.

In the embodiment of the present invention, the terminal device can transmit the N transmission versions in parallel, where the meaning of "parallel" is not necessarily the exact same timing, but one with data. This means that there is no need to wait for confirmation messages for other transmitted transmission versions before sending one transmission version.

At 309, the network device receives N transmission versions of the uplink data transmitted by the terminal device in the data transmission resource indicated by one or N scheduling configuration messages transmitted by the terminal device.

Decoding (that is, the coding sequences of a plurality of transmission versions are combined into one large coding sequence and then the decoding is performed) can also be performed.

As an option, if the network device successfully decodes any one transmission version, or if batch decoding is successful for the N transmission versions, then the terminal device can be used to transmit uplink data. The corresponding ACK (Acknowledge) message can be sent.

An option is to send a NACK (Non-Acknowledge) message to the terminal device if the network device has not successfully decrypted any of the transmission versions, or if the batch decryption for N transmission versions fails. can. Here, if the network device performs decoding for each of the transmission versions, the network device can send a NACK message to each of the transmission versions, and each NACK message is the corresponding transmission version. Can include instructional information, which allows the terminal device to know which transmission version failed to decrypt, and if the network device decodes for N transmission versions at once, the network device.

Can be grasped. Alternatively, the network device may establish a new data transmission resource and a new data transmission format, by sending the terminal device an uplink resource message containing the new data transmission format and the new data transmission resource. The terminal device can transmit uplink data based on the new data transmission format and the new data transmission resource. Here, the uplink resource message may be transmitted after the network device receives the uplink resource request, or receives a scheduling configuration message that is also used to request the uplink resource from the network device. In this case, the uplink resource message is also referred to as an uplink resource response, and a specific description thereof can be referred to with reference to FIG.

When the terminal device receives the NACK message sent from the network device, the terminal device can determine the new data transmission format, determine the new data transmission resource from the data resource pool, and the new data transmission format and Generates and sends a transmission version of uplink data according to new data transmission resources.

In the embodiment of the present invention, when the transmission of data (uplink or downlink) fails, the terminal device or the network device determines a new data transmission format and a new transmission resource as an example. Of course, if the data transmission fails, the new transmission resource can be determined by diverting the previous resource as the new data transmission format or diverting the previous resource.

Further, the present invention describes, as an example, that the data transmission resources of N transmission versions and the data transmission are different from each other. The N transmission versions in the embodiment of the present invention may use the same transmission format and different transmission resources, as long as the N transmission versions can be distinguished and transmitted smoothly.

Therefore, in the embodiment of the present invention, in order to generate and transmit a transmission version of the uplink data and also to transmit a scheduling configuration message to the network device, the terminal device determines the data transmission format and performs the uplink data. Select a data transmission resource from the data resource pool to indicate the data transmission resource and data transmission format used to transmit. It realizes a non-scheduled data transmission method, "the terminal device reports the resource scheduling request", "the network device schedules the uplink transmission resource for the terminal device", and "the terminal device is up". The delay can be reduced on the premise that the transmission reliability is not deteriorated by avoiding the three steps of "transmitting the link data".

Low latency and high reliability can be achieved at the same time.

FIG. 9 is a schematic flowchart of the communication method 400 according to the embodiment of the present invention.

At 401, the terminal device sends a scheduling configuration message to the network device, which is used to indicate the data transmission resource and data transmission format corresponding to the first transmission version of the uplink data.

At 402, the terminal device transmits the first transmission version of the uplink data to the network device.

In an embodiment of the invention, for the generation and transmission of the scheduling configuration message in 401 and 402 and the transmitted version of the uplink data, method 200 or 300 shown in FIG. 2 or 3 can be referred to for brevity. Above, omitted here.

At 403, the terminal device sends an uplink resource scheduling request to the network device, and the uplink resource scheduling request is used to request the network device to allocate an uplink transmission resource for the uplink data. Be done.

In the embodiment of the present invention, the uplink resource scheduling request has two embodiments, one is that the terminal device transmits a clear resource scheduling request, and in this method, the resource transmitted from the terminal. The scheduling request contains information related to the resource scheduling request and the first transmission version of the uplink data transmitted at the same time, that is, the resource scheduling request is not a scheduling request for other uplink data. It is clearly stated that it is for the uplink data, whereby the network device can clarify the reception status of the resource scheduling request for the uplink data. The second is that the resource scheduling request of the terminal is unclearly indicated by the scheduling configuration message in 401, in such a manner the terminal device no longer sends a single resource scheduling request.

In 404, the network device receives the first transmission version of the uplink data and demodulates and decodes it based on the scheduling configuration message transmitted from the terminal device, where the uplink reception, demodulation, and decoding methods. Can refer to the method 200 or 300 shown in FIG. 2 or FIG. 3, which is omitted here for brevity.

At 404, the network device sends an ACK / NACK or uplink resource allocation response to the terminal device based on the demodulation, decryption status of the first transmission version of the uplink data.

The network device is an acknowledgment message or a negative confirmation message (for example, ACK / NACK) and an uplink resource based on the status of demodulation and decoding of the transmission version for the first transmission version of the uplink data transmitted from the terminal device. It is determined whether to send an allocation response (for example, uplink permission (UL (Uplink) Grant)). specifically,
If the network device receives the first transmission version of the uplink data transmitted from the terminal device and successfully demolishes and decodes it (eg, successful CRC inspection), the network device corresponds to the data in the terminal device. If only an acknowledgment (ACK) is sent and an uplink resource scheduling request is received from the terminal, this uplink resource scheduling request is ignored.

If the network device receives the first transmission version of the uplink data transmitted from the terminal device, but the demodulation or decryption is not successful (eg CRC inspection failure), the network device employs the following two methods: do.

Method 1 is that if the network wants a second transmission version of the uplink data to be transmitted according to the network's scheduling, the network device will include information contained in the terminal uplink resource scheduling request and / and scheduling configuration message. Based on, an uplink resource is scheduled for the terminal and a corresponding uplink resource allocation response (UL Grant) is sent to the terminal device. The uplink resource allocation response specifies that the terminal device should transmit the transmission format and transmission resource of the second transmission version of the uplink data. After receiving the uplink resource allocation response, the terminal device ignores the ACK / NACK feedback of the network device and transmits a second transmission version of the uplink data based on the uplink resource allocation.

As method 2, if the network still wants the second transmission version of the uplink data to be transmitted by the terminal itself in a resource selection fashion, the network device does not send the uplink resource allocation response to the terminal but to the terminal. A negative confirmation (NACK) corresponding to the transmission version is transmitted. In this case, the terminal determines the transmission format by itself according to the same method as the first transmission, selects the transmission resource by itself from the resource pool, performs the second transmission, and here, the selected transmission resource. And the transmission format may be different from the first selection.

If the network device has not received the first transmission version of the uplink data transmitted by the terminal device, the network device is concerned based on the information contained in the terminal uplink resource scheduling request and / and the scheduling configuration message. The uplink resource is scheduled for the terminal, and the corresponding uplink resource allocation response (UL Grant) is transmitted to the terminal without having to send the ACK / NACK information.

For example, as shown in FIG. 10, at 404-1 the network device receives an uplink resource scheduling request. In 404-2, the network device determines whether or not the uplink data from the terminal device has been received, and if the result is negative, 404-3 is performed, and if the result is positive, 404-4. To carry out. At 404-3, the network device schedules an uplink resource for the terminal device and sends an uplink resource scheduling message to indicate the uplink resource to carry a second transmission version of the uplink data. do. In 404-4, the network device determines whether or not the uplink data from the terminal device has been successfully decoded, and if the result is affirmative, then 404-5 is performed, and if the result is negative, the result is negative. Carry out 404-6. At 404-5, the network device sends an ACK message to the terminal device. In 404-6, the network device chooses whether the terminal device wants to transmit the transmitted version of the uplink data according to the network scheduling, and if the result is negative, implements 404-7. If the result is affirmative, carry out 404-8. At 404-7, the network device sends a NACK message to the terminal device. At 404-8, the network device sends a scheduling uplink resource to the terminal device to indicate the uplink resource and transmission format for transmitting the second transmission version of the uplink data, and the uplink resource. It also sends an allocation response.

At 405, when the terminal device receives the uplink resource allocation response or NACK information, it transmits a third transmission version of the uplink data.

As an option, as shown in FIG. 11, when the terminal device receives the uplink resource allocation response (UL Grant), the second transmission of the uplink data is performed according to the data transmission resource and the data transmission format instructed by the UL Grant. Send the version (405-2). If UL Grant is not received, perform 405-3. In 405-3, if the received acknowledgment (ACK / NACK) message is NACK, the terminal device determines the transmission format itself, selects the transmission resource from the resource pool, and transmits the third transmission version of the uplink data. (405-4).

Therefore, in the embodiment of the present invention, a communication method that combines non-scheduling and scheduling is adopted, and such a method reduces reliability, deteriorates spectral efficiency, and demands power under any circumstances. No ascent is triggered, and conversely, low latency can be achieved in certain situations. In this method, the uplink is transmitted by first adopting a method without scheduling, and if the transmission is successful, the transmission delay can be significantly reduced. If the transmission fails, it can be switched to adopt the scheduling method, the same reliability as the current system can be obtained, and at the same time, the delay is not increased.

FIG. 12 is a schematic flowchart of the communication method 500 according to the embodiment of the present invention.

At 501, the network device determines the data transmission resource and data transmission format corresponding to each transmission version based on the quantity M of the transmission version of the downlink data to be transmitted.

At 502, the network device generates each transmission version based on the data transmission format corresponding to each transmission version and transmits the transmission version by the corresponding data transmission resource.

Optionally, in an embodiment of the invention, the network device may transmit multiple transmission versions in parallel to the terminal device, where the meaning of "parallel" does not necessarily mean exactly the same timing. This means that there is no need to wait for confirmation messages for other transmitted transmission versions before transmitting one transmission version with data.

At 503, the terminal device feeds back a confirmation message to the base station based on the demodulation and decryption status.

As an option, in the embodiments of the present invention, the terminal may decode each transmission version individually, and decodes all at once for any number of transmission versions in order to obtain a better decoding effect. May be.

If the terminal device decodes each first transmission version individually, and if there are successfully decoded transmission versions in the M first transmission versions, a positive confirmation ACK message is sent to the network device and each If the first transmission version is individually decoded and none of the M transmission versions are successfully decoded, a negative confirmation NACK message is sent to the network device, where the network device is decrypted. The NACK message contains information on the failed first transmission version so that the failed first transmission version can be known.

Alternatively, if the batch decoding is performed for the M first transmission versions and the batch decoding is successful, an acknowledgment ACK message is transmitted to the network device.

If the batch decoding is performed for the M first transmission versions and the batch decoding fails, a negative confirmation NACK message is sent to the network device, where the NACK message is encoded by the N pieces. Contains version information.

As an option, in the embodiment of the present invention, when the network device receives the NACK message transmitted from the terminal device, the data transmission resource and the data transmission format can be selected again, and the data transmission resource can be selected again. Generates a transmission version based on the data transmission format and sends it to the terminal device.

In an embodiment of the invention, by transmitting multiple transmission versions of one downlink data in parallel in a plurality of resources, the failure of a radio link on a resource due to channel fading and interference can be effectively overcome. It can improve the reliability of transmission and reduce the delay due to the simple retransmission of the time domain.
