Detailed Description

The basic mechanism of DRX is to configure a terminal in radio resource control (RRC, radio Resource Control) connected state with one DRX cycle. As shown in fig. 1, one DRX cycle consists of an active period (On Duration) configured by an active period timer DRX-onduration timer and a sleep period (Opportunity for DRX), during which the terminal listens for and receives the PDCCH; during the sleep period, the terminal may turn off the receiver and not receive the PDCCH, thereby reducing power consumption. In connection with fig. 1, in the time domain, time is divided into successive DRX cycles. The DRX cycle is selected taking into account the balance between power consumption and duration: in one aspect, a long DRX cycle is beneficial for extending the battery life of the terminal, e.g., the terminal does not need to continuously receive downlink data while the user is reading a web page that has been downloaded during web browsing. On the other hand, a short DRX cycle is beneficial for faster response when new data needs to be transmitted.

Based on the DRX mechanism, a terminal in one DRX cycle will enter the active period only when the active period timer is started, and the extension of the active period can only occur after the active period timer is started, that is, as long as the data arrives in the sleep period, the terminal must wait until the next DRX cycle, that is, the next active period timer is started, which definitely causes a delay to the transmission of the data. If a faster response is desired, a shorter DRX cycle should be used, which affects the power consumption of the terminal, and if a longer DRX cycle should be used, which affects the response time of the terminal.

Based on this, in various embodiments of the present application, a first base station transmits first information to a first terminal; the first information is used for indicating the terminal to enter the DRX activation period before the activation period timer is started. By the scheme, the starting time of the DRX activation period can be advanced, so that the starting time of the new DRX activation period is aligned with the arrival time of the actual downlink traffic as much as possible, and the data transmission delay is reduced.

The present application will be described in further detail with reference to the accompanying drawings and examples.

The embodiment of the application provides a configuration method of DRX, which is applied to a first base station, and referring to FIG. 2, the method comprises the following steps:

step 201: and sending the first information to the first terminal.

The first information is used for indicating the terminal to enter the DRX activation period before the activation period timer is started.

For example, if downlink data will arrive in the DRX sleep period, the first base station may start the DRX active period in advance by transmitting first information to the first terminal, so that the terminal enters the DRX active period in advance and receives the downlink data.

In actual application, the terminal can inform the base station whether the terminal supports the advanced starting of the DRX activation period through the terminal capability reporting flow of the RRC layer.

In an embodiment, the sending the first information to the first terminal includes:

and sending a first WUS to the first terminal.

Wherein the first WUS carries the first information.

In the related art, in order to avoid unnecessary power consumption caused by waking up the terminal in a DRX cycle without data scheduling, WUS based on PDCCH is used. WUS is a cyclic redundancy check (CRC, cyclic Redundancy Check) format 2_6 of downlink control information (DCI, downlink Control Information) scrambled with a Power save radio network temporary identifier (PS-RNTI, power save-Radio Network Temporary Identifier). When a New air interface (NR, new Radio) base station (gNB) needs to perform uplink scheduling or downlink scheduling on a certain terminal, a WUS signal is sent to the terminal, and a field value of a Wake-up indication field is set to 1, so as to inform the terminal to start an activation period timer in a next long DRX cycle. When the gNB does not schedule the terminal in the next long DRX period, the gNB sends a WUS signal to the terminal, and the field value of the Wake-up indication field is set to 0, so that the terminal does not start an activation period timer in the next DRX period, but continues to sleep, thereby reducing the power consumption of the terminal and improving the service time of a battery.

In the embodiment of the application, a field can be added in the WUS, and by taking different field values for the field, whether the DRX active period needs to be activated in advance is indicated. In one embodiment, the first field in the first WUS takes a set field value; the set field value characterizes the first information. Further, the first field is located after a wake-up indication field or a secondary cell sleep indication field of the first WUS.

Specifically, as shown in fig. 3, a 1-bit "Active Indication" field may be added after the block consisting of the "Wake-up indication" field and the "SCell dormancy indication" field of WUS. In addition, not shown in fig. 3, if the "SCell dormancy indication" field does not exist, a 1-bit "Active Indication" may be added after the "Wake-up indication" field. Here, if the value of the "Active Indication" field is 1, the terminal is instructed to enter the DRX active period before the active period timer starts and to attempt to receive the PDCCH; if the value of the "Active Indication" field is 0, it indicates that the terminal needs to wait until the next DRX cycle is awakened, and then attempt to receive the PDCCH during the corresponding DRX active period.

The first terminal determines when to enter a DRX active period after receiving the first information. Wherein the first information is used to indicate one of:

the terminal immediately enters a DRX activation period;

the terminal enters a DRX activation period after a set time length;

the terminal enters the DRX active period when the active period timer starts.

Here, the terminal may enter the DRX active period immediately after receiving the first information, or may enter the DRX active period after setting the duration, or may enter the DRX active period when the active period timer starts, based on a pre-negotiation with the network side, or based on a capability configuration of the terminal itself.

In practical application, after the terminal enters the DRX active period in advance, the DRX active period may be kept until the active period timer starts, or the duration of the terminal in the DRX active period before the active period timer starts may be configured by the network side, and specifically, the first base station may configure the duration to the first terminal through RRC parameters. Based on this, in an embodiment, the method further comprises:

configuring a first timer for the first terminal; wherein,

Illustratively, the first timer may be named drx-earlyactiontimer. In actual application, a first timer is configured for the first terminal through the first base station, when the first terminal enters the DRX activation period in advance, the duration of the DRX activation period does not necessarily need to be extended to the time when the activation period timer starts, but the DRX activation period which enters in advance can be ended before the activation period timer starts, so that the first terminal is in the DRX dormant period as far as possible under the condition of no data scheduling, and the power consumption of the terminal is reduced.

Further, in an embodiment, the method further comprises:

configuring a second timer for the first terminal; wherein,

the second timer is started after the medium access control layer MAC entity decodes the first PDCCH and is used for indicating that the terminal is in a DRX activation period during the operation of the second timer; and the first PDCCH characterizes PDCCH indicating the primary transmission data of uplink or downlink.

The second timer may be named, for example, drx-earlyInactivityTimer. In practical application, the first base station configures a second timer for the first terminal. After the MAC entity successfully decodes a PDCCH indicating uplink or downlink primary transmission data, the first terminal starts a second timer, and the terminal is always in the DRX active period during the operation of the second timer. By configuring the second timer, after the MAC entity successfully decodes a PDCCH indicating the uplink or downlink primary transmission data, the duration of the DRX activation period indicated by the first timer can be updated, so that the transmission of the data can be ensured.

Correspondingly, the embodiment of the application also provides a DRX configuration method which is applied to the first terminal.

Referring to fig. 4, the method includes:

step 401: and receiving the first information sent by the first base station.

In an embodiment, the receiving the first information sent by the first base station includes:

receiving a first WUS sent by a first base station; wherein,

the first WUS carries the first information.

the terminal immediately enters a DRX activation period;

the terminal enters a DRX activation period after a set time length;

the terminal enters the DRX active period when the active period timer starts.

Accordingly, according to the difference of indication meanings of the first information, the timing of the terminal to enter the DRX active period in advance is also different. In an embodiment, after the receiving the first information sent by the first base station, the method further includes:

immediately entering a DRX active period;

entering a DRX activation period after a set duration;

the DRX active period is entered when the active period timer starts.

And starting the first timer under the condition that the first terminal enters the DRX activation period before the activation period timer is started.

Further, in an embodiment, the method further comprises:

In an embodiment, the method further comprises:

Based on the scheme, the data transmission delay caused by the DRX period can be effectively reduced. Specifically, referring to fig. 5, the terminal enters the DRX active period in advance before the active period timer starts, in contrast to the fact that the related art needs to enter the DRX active period when the activator timer starts, it can be seen that after the scheme is adopted, the time for the terminal to start monitoring the PDCCH is advanced, when downlink data is sent out, the transmission delay of the downlink data to the terminal is obviously reduced, and the new active time of the DRX active period is aligned with the arrival time of the actual downlink traffic as much as possible through network side configuration, so that the data transmission delay is reduced. In practical application, the scheme can be applied to Ultra-Reliable Low-latency communication (URLLC) and internet of things (IoT, internet of Things) scenes to solve the data transmission delay caused by the DRX mechanism. In addition, the network side can indicate to the terminal to enter the DRX activation period in advance by adding a field in the WUS, so that the overhead generated when the indication information is issued is small, and the network load is not caused.

In addition, in the Extended Reality (XR) technology, due to random delay caused by a frame encoder in an edge server, transmission delay in a core network, and the like, the arrival of XR downlink traffic has jitter, resulting in random frame arrival time. Then, if the traffic arrives in the DRX sleep period, the data packet needs to wait until the terminal wakes up from the DRX sleep period to transmit, resulting in an increase in transmission delay of the data packet. In view of the shortage of downlink physical resource blocks (PRBs, physical Resource Block), the increase in transmission delay may negatively affect the capacity: for example, the terminal originally expects data to arrive in the DRX active period, and the data arrives after the DRX active period due to jitter, at this time, the terminal may continue to monitor the PDCCH in the DRX active period, thereby causing unnecessary PDCCH monitoring, and increasing power consumption of the terminal. By adopting the scheme, when the traffic arrives in the DRX dormant period, the terminal can be awakened in the DRX dormant period, enter the DRX active period in advance and receive the data packet, so that the influence caused by jitter is reduced.
