The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

Technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In the new NR, the network device may configure the DRX function for the terminal device, so that the terminal device discontinuously monitors the PDCCH, thereby achieving the purpose of power saving of the terminal device. For example, the MAC entity for the terminal device contains DRX configuration parameters, which include: a DRX activation timer (DRX-onduration timer), a DRX inactivity timer (DRX-InactionTimer), an uplink DRX retransmission timer (DRX-RecransmittionTimerUL), a downlink DRX retransmission timer (DRX-RecransmittionTimerDL), a downlink DRX-HARQ round trip time timer (DRX-HARQ-RTT-TimerDL), an uplink DRX-HARQ round trip time timer (DRX-HARQ-RTT-TimerUL).

Referring to fig. 1, the DRX cycle includes an active period (onDuration) in which a terminal device listens to and receives a PDCCH, and a sleep period in which the terminal device does not listen to the PDCCH, so that power consumption can be reduced. If the terminal device is configured with DRX, the terminal device needs to monitor PDCCH during the DRX activation period. The DRX active period includes several cases:

(1) Any one of the timers DRX-onDurationTimer, DRX-InactivityTimer, DRX-Recransmission TimerDL and DRX-Recransmission TimerUL is running;

(2) The terminal device has sent a scheduling request on PUCCH and the scheduling request is in a pending (pending) state.

Further, in the DRX processing process, the terminal device starts a DRX-HARQ-RTT timer after completing uplink transmission or completing HARQ feedback for downlink transmission, and the terminal device is in a dormant state during the running period of the DRX-HARQ-RTT timer, does not monitor the PDCCH, and starts to monitor uplink retransmission scheduling after the DRX-HARQ-RTT timer is overtime, or determines whether to start monitoring downlink retransmission scheduling according to the feedback condition.

At present, the uplink and the downlink of the new NR support the HARQ mechanism, so that two timers, namely DRX-HARQ-RTT-TimerUL and DRX-HARQ-RTT-TimerDL, are used in the DRX processing process, and the two parameters reflect the minimum time interval required by the terminal equipment from uplink transmission to receiving retransmission scheduling issued by the network, namely the time of one RTT. Wherein the DRX-HARQ-RTT-TimerUL and DRX-HARQ-RTT-TimerDL may be semi-statically configured by a network radio resource control (Radio Resource Control, RRC).

However, in the above technical solution, HARQ feedback may increase the delay of data transmission, resulting in longer data transmission delay in the DRX processing, which is difficult to satisfy an application scenario with higher delay requirement, for example, the third generation partnership project (3rd Generation Partnership Project,3GPP) is currently researching a non-terrestrial communication network (Non Terrestrial Network, NTN) technology, where NTN generally adopts a satellite communication manner to provide a communication service for a terrestrial user, and compared with a cellular network adopted by a conventional NR, the signal propagation delay between a terminal device and a satellite in the NTN network is greatly increased, which is difficult to satisfy the delay requirement of the NTN network.

In view of the foregoing, an embodiment of the present application provides a method for processing DRX, where a terminal device configures a DRX timer corresponding to an HARQ process based on configuration information sent by a network device, where the configuration information includes a state parameter indicating to turn on or off an HARQ feedback function corresponding to the HARQ process. Based on the technical scheme of the embodiment of the application, the terminal equipment configures the DRX timer corresponding to the HARQ process based on the configuration information sent by the network equipment, on one hand, the state parameter in the configuration information can indicate to close the HARQ feedback function corresponding to the HARQ process, so that the data transmission delay in the data scheduling transmission process can be reduced; on the other hand, the DRX timer corresponding to the HARQ process is configured based on the configuration information, and the timer in the DRX processing process can be configured according to the configuration information indicating that the HARQ feedback function is switched off to on or switched on to off, so that PDCCH monitoring of the terminal equipment can be adapted to the on/off control of the network on the HARQ feedback function, the terminal equipment is prevented from missing the receiving of the PDCCH, and the purpose of reducing the power consumption can be achieved.

The following describes in detail the processing method of DRX provided in the present application through several specific embodiments.

Fig. 3 is a flowchart of an embodiment one of a processing method of DRX provided in the embodiment of the present application, as shown in fig. 3, where the processing method of DRX may be applied to a terminal device, and specifically includes the following steps:

step S310: and receiving configuration information sent by the network equipment, wherein the configuration information comprises state parameters for indicating to start or stop the HARQ feedback function corresponding to the HARQ process.

In an example embodiment, the network device sends configuration information to the terminal device, where the configuration information includes a status parameter indicating to turn on or off a HARQ feedback function corresponding to the HARQ process. Specifically, the state parameter may instruct the terminal device to switch the HARQ feedback function corresponding to the HARQ process from the on state to the off state, or to switch the HARQ feedback function corresponding to the HARQ process from the off state to the on state.

Further, for a plurality of HARQ processes corresponding to the terminal device, the HARQ feedback functions of all HARQ processes may be configured to be in an on state or an off state, or the HARQ feedback functions of some HARQ processes in the plurality of HARQ processes may be configured to be in an on state, and the HARQ feedback functions of other HARQ processes may be configured to be in an off state.

In an example embodiment, the status parameter may be configured by the network device through RRC signaling, but embodiments of the present application are not limited thereto, and for example, the status parameter may also be configured through downlink control information (Downlink Control Information, DCI), which is not particularly limited herein.

Step S320: and configuring the DRX timer corresponding to the HARQ process based on the configuration information.

In an example embodiment, the terminal device determines a state parameter in the configuration information, where the state parameter indicates to turn on or off a HARQ feedback function corresponding to the HARQ process, and configures a DRX timer corresponding to the HARQ process based on the state parameter. Therefore, when the state parameters are different, configuring the DRX timer corresponding to the HARQ process at least includes the following implementation manners:

in a first implementation manner, if an HARQ feedback function corresponding to an HARQ process is in an on state before receiving configuration information, where a state parameter in the configuration information indicates to close the HARQ feedback function corresponding to the HARQ process, configuring a DRX timer corresponding to the HARQ process based on the configuration information, including: if the configuration information is received during the running period of the HARQ round trip time timer corresponding to the HARQ process, stopping the HARQ round trip time timer and starting the DRX retransmission timer corresponding to the HARQ process.

Further, in this example embodiment, if the HARQ process is an uplink HARQ process, the HARQ round-trip time timer is an uplink HARQ round-trip time timer, and the DRX retransmission timer is an uplink DRX retransmission timer; if the HARQ process is a downlink HARQ process, the HARQ round-trip time timer is a downlink HARQ round-trip time timer and the DRX retransmission timer is a downlink DRX retransmission timer.

In a second implementation manner, if the HARQ feedback function corresponding to the HARQ process is in an off state before receiving the configuration information, and a state parameter in the configuration information indicates to turn on the HARQ feedback function corresponding to the HARQ process, configuring a DRX timer corresponding to the HARQ process based on the configuration information, where the configuring includes: and if the configuration information is received in the running period of the DRX retransmission timer corresponding to the HARQ process, stopping the DRX retransmission timer.

Further, in this example embodiment, if the HARQ process is an uplink HARQ process, the DRX retransmission timer is an uplink DRX retransmission timer; if the HARQ process is a downlink HARQ process, the DRX retransmission timer is a downlink DRX retransmission timer.

According to the technical scheme of the embodiment of the application, the terminal equipment configures the DRX timer corresponding to the HARQ process based on the configuration information sent by the network equipment, and on one hand, the state parameter in the configuration information can indicate to close the HARQ feedback function corresponding to the HARQ process, so that the data transmission delay in the DRX processing process can be reduced; on the other hand, the DRX timer corresponding to the HARQ process is configured based on the configuration information, and the timer in the DRX processing process can be configured according to the configuration information from off to on or from on to off of the HARQ feedback function, so that the PDCCH monitoring of the terminal equipment can be adapted to the on/off control of the network on the HARQ feedback function, the terminal equipment is prevented from missing the receiving of the PDCCH, and the purpose of reducing the power consumption can be achieved.

Further, in an example embodiment, the configuration information may also include the number of HARQ process procedures. Further, in some example embodiments, the number of HARQ processes may further include a number of HARQ processes requiring the HARQ feedback function to be turned off, and specifically, for a plurality of HARQ processes of the terminal device, the number of HARQ processes requiring the HARQ feedback function to be turned off among the plurality of HARQ processes may be determined according to delay information and reception reliability information in a data scheduling transmission process. For example, if the delay in the data scheduling transmission process increases, the number of HARQ processes for which the HARQ feedback function is configured to be in the off state may be increased; if the reliability of reception in the data scheduling transmission process is reduced, the number of HARQ processes in which the HARQ feedback function is configured in the off state can be reduced.

On the basis of the above embodiments, the implementation scheme of the DRX processing method in the specific application process is described in detail below through several specific embodiments with reference to the accompanying drawings.

Example 1

further, in other embodiments, in the configuration information, for each serving cell of the terminal device, an UpLink (UL) bandwidth Part (BWP) is configured to indicate one, and for each UL BWP of the at least one UL BWP, in one embodiment, the reserved UpLink HARQ process number may be configured.

Step 2, for the uplink HARQ process with the HARQ feedback function in step 1 in an on state, if the terminal device receives the PDCCH for scheduling uplink initial transmission or retransmission, the terminal device starts the DRX-HARQ-RTT-TimerUL after the PUSCH transmission is finished (during the running period of the DRX-HARQ-RTT-TimerUL timer, the terminal device does not monitor the PDCCH), and starts the DRX-retransmission TimerUL after the DRX-HARQ-RTT-TimerUL times out.

And 3, in the running period of the DRX-HARQ-RTT-TimerUL, if the terminal equipment receives a state parameter configured by the network equipment through RRC signaling, the state parameter indicates the terminal equipment to close the HARQ feedback function of the uplink HARQ process, the terminal equipment stops running DRX-HARQ-RTT-TimerUL and starts DRX-retransmission TimerUL, and starts to monitor the PDCCH immediately.

Fig. 4 is a schematic flow chart of a specific implementation of the first embodiment, and the first embodiment is described in detail below with reference to fig. 4.

Referring to fig. 4, in step S410, the terminal device receives RRC configuration information sent by the network device, where the configuration information includes a status parameter indicating that the uplink HARQ starts the HARQ feedback function.

In an example embodiment, the RRC configuration information is carried by the PDSCH, the configuration information including at least the following information:

(b) Configuration parameters of uplink HARQ processes, including the number of uplink HARQ processes, and state parameters of the state in which the HARQ feedback function of each uplink HARQ process is located (i.e., whether to turn on the HARQ feedback function or turn off the HARQ feedback function)

Further, the configuration information includes a status parameter indicating that the uplink HARQ ID0 turns on the HARQ feedback function, and ID0 indicates that the process identifier of the uplink HARQ process is ID0.

In step S415, the terminal device receives a PDCCH sent by the network device and used for scheduling uplink initial transmission or retransmission.

In an example embodiment, the terminal device receives a PDCCH indicating uplink scheduling sent by the network device, and a process identifier of an uplink HARQ process used by the uplink scheduling PDCCH is ID0.

In step S420, after the PUSCH transmission is finished, the terminal device starts the HARQ-RTT-timer ul corresponding to the HARQ process.

In step S425, after the HARQ-RTT-timer ul times out, the terminal device starts the DRX-retransmission timer ul corresponding to the HARQ process.

In step S430, the terminal device receives a PDCCH sent by the network device and used for scheduling uplink initial transmission or retransmission.

In step S435, after the PUSCH transmission is ended, the terminal device starts the HARQ-RTT-timer ul corresponding to the HARQ process.

In step S440, during the operation of HARQ-RTT-timer ul, the terminal device receives configuration information sent by the network device, where the configuration information includes a status parameter indicating that the uplink HARQ turns off the HARQ feedback function.

In step S450, the terminal device stops the HARQ-RTT-timer ul corresponding to the HARQ process, starts the DRX-retransmission timer ul corresponding to the HARQ process, and starts to monitor the PDCCH.
