[0025] In order to be able to understand the features and technical content of the embodiment of this application in more detail, the implementation of the embodiment of this application will be elaborated in detail below with reference to the accompanying drawings. The accompanying drawings are only for reference and explanation purposes and are not used to limit the embodiment of this application.

[0026] The non-terrestrial communication network (Non Terrestrial Network, NTN) uses satellite communication to provide communication services to ground users. Compared with terrestrial cellular network communication, satellite communication has many unique advantages. First of all, satellite communication is not restricted by the user's geographical location. For example, general terrestrial communication cannot cover areas such as the ocean, mountains, or deserts where communication equipment cannot be set up or where communication coverage is not provided due to sparse population; for satellite communication, since one satellite can cover a large area of the ground and the satellite can orbit the earth, theoretically every corner of the earth can be covered by satellite communication. Secondly, satellite communication has high social value. Satellite communication can be covered in remote mountainous areas, poor and backward countries or regions at a relatively low cost, enabling people in these areas to enjoy advanced voice communication and mobile Internet technologies, which is conducive to narrowing the digital divide with developed regions and promoting the development of these regions. Thirdly, satellite communication has a long communication distance, and increasing the communication distance does not significantly increase the communication cost; finally, satellite communication has high stability and is not restricted by natural disasters.

[0027] Communication satellites are classified into Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, High Elliptical Orbit (HEO) satellites, etc. according to different orbital altitudes. A brief introduction to LEO and GEO is given below.

[0028] The orbital altitude range of LEO is from 500 km to 1500 km, and the corresponding orbital period is about 1.5 hours to 2 hours. The signal propagation delay of single-hop communication between terminal devices is generally less than 20 ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is small, and the requirement for the transmission power of terminal devices is not high.

[0029] The orbital altitude of GEO is 35786 km, and the rotation period around the earth is 24 hours. The signal propagation delay of single-hop communication between terminal devices is generally 250 ms. In order to ensure the satellite coverage and improve the system capacity of the entire satellite communication system, the satellite uses multi-beam to cover the ground. One satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover a ground area with a diameter of dozens to hundreds of kilometers.

[0030] In the NR system, the network device can configure the Discontinuous Reception (DRX) function for the terminal device. The terminal device listens to the PDCCH discontinuously, so as to achieve the purpose of power saving of the terminal device. Each Medium Access Control (MAC) entity has a DRX configuration; the configuration parameters of DRX include:

[0031] 1) DRX on-duration timer, the duration for which the terminal device wakes up at the start of a DRX cycle.

[0032] 2) DRX slot offset, the time delay for the terminal device to start the drx-onDuration timer.

[0033] 3) DRX inactivity timer, the duration for which the terminal device continues to listen to the PDCCH after receiving a PDCCH indicating an uplink initial transmission or a downlink initial transmission.

[0034] 4) DRX Downlink Retransmission Timer (drx-RetransmissionTimerDL): The maximum duration for which the terminal device listens for the PDCCH indicating downlink retransmission scheduling. Each downlink HARQ process except the broadcast HARQ process corresponds to a DRX–RetransmissionTimerDL.

[0035] 5) DRX Uplink Retransmission Timer (drx-RetransmissionTimerUL): The maximum duration for which the terminal device listens for the PDCCH indicating uplink retransmission scheduling. Each uplink HARQ process corresponds to a DRX-RetransmissionTimerUL.

[0036] 6) DRX Long Cycle Start Offset (drx-LongCycleStartOffset): Used to configure the Long DTX cycle (LongDRX cycle), and the subframe offset at which the Long DRX cycle and the Short DRX cycle (Short DRX Cycle) start.

[0037] 7) DRX Short Cycle (drx-ShortCycle): An optional configuration.

[0038] 8) DRX Short Cycle Timer (drx-ShortCycleTimer): The duration for which the terminal device is in the Short DRX cycle (and has not received any PDCCH), which is an optional configuration.

[0039] 9) drx-HARQ-RTT-TimerDL: The minimum waiting time required for the terminal device to expect to receive the PDCCH indicating downlink scheduling. Each downlink HARQ process except the broadcast HARQ process corresponds to a DRX-HARQ-RTT-TimerDL;

[0040] 10) drx-HARQ-RTT-TimerUL: The minimum waiting time required for the terminal device to expect to receive the PDCCH indicating uplink scheduling. Each uplink HARQ process corresponds to a drx-HARQ-RTT-TimerUL.

[0041] If the terminal device is configured with DRX, the terminal device needs to listen for the PDCCH during the DRX Active Time. The DRX Active Time includes the following situations:

[0042] 1) Any one of the following 5 timers is running: drx-onDurationTimer, drx-InactivityTimer, drx–RetransmissionTimerDL, drx-RetransmissionTimerUL, and ra-ContentionResolutionTimer.

[0043] 2) A scheduling request (SR) has been sent on the PUCCH and is in a pending state.

[0044] 3) In a contention-based random access procedure, the terminal device has not received an initial transmission indicated by a PDCCH scrambled with a cell radio network temporary identifier (C-RNTI) after successfully receiving a random access response.

[0045] Schematic diagram of the DRX cycle of the terminal device, as Figure 1 shown, the terminal device decides when to start the drx-onDurationTimer based on whether it is currently in a short DRX cycle or a long DRX cycle. The specific provisions are as follows:

[0046] 1) If the terminal device is currently in a Short DRX Cycle and the current subframe satisfies [(SFN × 10) + subframe number] modulo (drx-ShortCycle) = (drx-StartOffset) modulo (drx-ShortCycle); or

[0047] 2) If the terminal device is currently in a Long DRX Cycle and the current subframe satisfies [(SFN × 10) + subframe number] modulo (drx-LongCycle) = drx-StartOffset:

[0048] Then start the drx-onDurationTimer at the moment after drx-SlotOffset slots starting from the current subframe.

[0049] The conditions for the terminal device to start or restart the drx-InactivityTimer are:

[0050] If the terminal device receives a PDCCH indicating a downlink or uplink initial transmission, the terminal device starts or restarts the drx-InactivityTimer.

[0051] The conditions for the terminal device to start and stop the drx-RetransmissionTimerDL are as follows:

[0052] When the terminal device receives a PDCCH indicating a downlink transmission, or when the terminal device receives a MAC PDU on the configured downlink grant resource, the terminal stops the drx-RetransmissionTimerDL corresponding to this HARQ process. After the terminal device completes the transmission of the HARQ process feedback for this downlink transmission, it starts the drx-HARQ-RTT-TimerDL corresponding to this HARQ process.

[0053] If the timer drx-HARQ-RTT-TimerDL corresponding to a certain HARQ of the terminal device expires and the downlink data transmitted using this HARQ process is decoded unsuccessfully, the terminal device starts the drx-RetransmissionTimerDL corresponding to this HARQ process.

[0054] The conditions for the terminal device to start and stop the drx-RetransmissionTimerUL are as follows:

[0055] When the terminal device receives a PDCCH indicating an uplink transmission, or when the terminal device sends a MAC PDU on the configured uplink grant resource, the terminal device stops the drx-RetransmissionTimerUL corresponding to this HARQ process. After the terminal device completes the first repetition of this PUSCH, it starts the drx-HARQ-RTT-TimerUL corresponding to this HARQ process.

[0056] If the timer drx-HARQ-RTT-TimerUL corresponding to a certain HARQ of the terminal device expires, the terminal device starts the drx-RetransmissionTimerUL corresponding to this HARQ process.

[0057] According to the above DRX process, it can be seen that after the terminal device completes the uplink transmission or completes the HARQ process feedback for the downlink transmission, it will first start a DRX HARQ RTT timer (drx-HARQ-RTT-TimerUL for uplink transmission and drx-HARQ-RTT-TimerDL for downlink transmission). The terminal device is in a dormant state during the operation of this DRX HARQ RTT timer and does not monitor the PDCCH. After the DRX HARQ RTT timer expires, the terminal device starts to monitor the uplink retransmission scheduling or determines whether to start monitoring the downlink retransmission scheduling according to the feedback of the HARQ process. Among them, drx-HARQ-RTT-TimerUL and drx-HARQ-RTT-TimerDL are semi-statically configured by the network device through Radio Resource Control (RRC) signaling.

[0058] In the NR system, both uplink transmission and downlink transmission support the HARQ mechanism; therefore, two timers, drx-HARQ-RTT-TimerUL and drx-HARQ-RTT-TimerDL, are used in the DRX process. The durations of these two timers represent the minimum time interval required for the terminal device to receive the retransmission scheduling sent by the network device after the uplink transmission. This minimum time interval includes the round-trip delay (RTT) and the processing time of the network device. In NTN, the signal propagation delay between the terminal device and the satellite increases significantly. To enable the network device to more precisely control drx-HARQ-RTT-TimerUL and drx-HARQ-RTT-TimerDL, a time offset can be introduced for the start of drx-HARQ-RTT-TimerUL and drx-HARQ-RTT-TimerDL, that is, after the terminal device completes the PUSCH transmission or the NACK feedback for the downlink reception, drx-HARQ-RTT-TimerUL or drx-HARQ-RTT-TimerDL is started after experiencing an offset.

[0059] Compared with the cellular network used in the traditional NR system, the signal propagation delay between the terminal device and the satellite in NTN increases significantly. To avoid increasing the number of HARQ processes and ensure the continuity of data transmission, the scheme of enabling or disabling HARQ is currently being discussed in the standardization process, and the following clear conclusions have been formed:

[0060] (1) The network device can configure whether to enable the HARQ function.

[0061] (2) If the HARQ function is turned off, the terminal device does not need to send HARQ feedback for the PDSCH to the network device.

[0062] (3) In the case of turning off HARQ feedback, to ensure the reliability of data transmission, HARQ retransmission is still supported.

[0063] (4) The configuration of turning the HARQ function on or off can be based on the terminal device or based on the HARQ process. For the configuration method based on the terminal device, that is, the HARQ functions of all HARQ processes of the terminal device are configured to be in the on or off state simultaneously. For the configuration method based on the HARQ process, that is, for multiple HARQ processes of a terminal device, the HARQ functions of some of the HARQ processes can be configured to be in the on state, and the HARQ functions of another part of the HARQ processes can be configured to be in the off state.

[0064] However, for the scenarios where the HARQ function is switched from on to off, or the HARQ function is switched from off to on, in order to simplify the processing flow of the communication system, what operations the terminal device needs to perform have not been clearly defined; and how to implement the DRX process in the scenarios where the HARQ function is switched from on to off, or the HARQ function is switched from off to on, has not been clearly defined.

[0071] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technologies, mobile communication systems will not only support traditional communication, but also support, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), and vehicle-to-vehicle (V2V) communication.

The embodiments of the present application do not limit this.

[0077] Optionally, the communication system 100 may further include other network entities such as a network controller and a mobility management entity. The embodiments of the present application do not limit this.

[0078] It should be understood that in the embodiments of the present application, a device with communication functions in a network / system may be referred to as a communication device. Taking Figure 2 the shown communication system 100 as an example, the communication device may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above and will not be elaborated here; the communication device may also include other devices in the communication system 100, such as other network entities such as a network controller and a mobility management entity. The embodiments of the present application do not limit this.

[0079] An optional processing flow of the information processing method provided by the embodiments of the present application, as Figure 3 shown, at least includes the following steps:

[0080] Step S201, when the attribute of the HARQ process changes, the media access control (MAC) entity of the terminal device resets the HARQ process.

[0081] In some embodiments, the attribute of the HARQ process may include the feedback function of the HARQ process; the change in the attribute of the HARQ process may include: the feedback function of the HARQ process is switched from on to off; or, the feedback function of the HARQ process is switched from off to on.

[0082] In some embodiments, when the attributes of the HARQ process change and are transmitted through DCI, the network device sends first indication information to the physical layer entity of the terminal device, and the first indication information is used to indicate resetting the HARQ process; the physical layer entity then sends the first indication information to the MAC entity of the terminal device, and the MAC entity resets the HARQ process according to the first indication information. Alternatively, when the attributes of the HARQ process change and are transmitted through RRC signaling, the network device sends first indication information to the RRC entity of the terminal device, and the RRC entity then sends the first indication information to the MAC entity of the terminal device, and the MAC entity resets the HARQ process according to the first indication information.

[0083] In some embodiments, when the HARQ process is an uplink HARQ process, the MAC entity of the terminal device resetting the HARQ process includes at least one of the following:

[0084] Empty the buffer of the uplink HARQ process;

[0085] Stop the drx-RetransmissionTimerUL corresponding to the running uplink HARQ process;

[0086] Stop the drx-HARQ-RTT-TimerUL corresponding to the running uplink HARQ process;

[0087] Stop the HARQ-RTT-offset-Timer corresponding to the running uplink HARQ process, and the running duration of the HARQ-RTT-offset-Timer is the start time offset of starting the drx-HARQ-RTT-TimerUL timer for the uplink HARQ process after the terminal device completes PUSCH transmission using the uplink HARQ process;

[0088] Stop the configuredGrantTimer corresponding to the running uplink HARQ process;

[0089] Configure the value of the New Data Indicator (NDI) of the uplink HARQ process to 0.

[0090] When the HARQ process is an uplink HARQ process, for the DRX process, the terminal device may also start or restart the drx-RetransmissionTimerUL corresponding to the uplink HARQ process. The terminal device may also stop the drx-HARQ-RTT-TimerUL timer corresponding to the uplink HARQ process that is running. The terminal device may also stop the HARQ-RTT-offset-Timer corresponding to the uplink HARQ process that is running. The duration of the HARQ-RTT-offset-Timer is the offset of the start time when the terminal device starts the drx-HARQ-RTT-TimerUL for the uplink HARQ process after completing the PUSCH transmission using the uplink HARQ process.

[0091] In some other embodiments, when the HARQ process is a downlink HARQ process, the reset of the HARQ process by the MAC entity of the terminal device includes at least one of the following:

[0092] Empty the buffer of the downlink HARQ process;

[0093] Stop the drx-RetransmissionTimerDL corresponding to the downlink HARQ process that is running;

[0094] Stop the drx-HARQ-RTT-TimerDL corresponding to the downlink HARQ process that is running;

[0095] Stop the HARQ-RTT-offset-Timer corresponding to the downlink HARQ process that is running. The duration of the HARQ-RTT-offset-Timer is the offset of the start time when the terminal device starts the drx-HARQ-RTT-TimerDL for the downlink HARQ process after completing the NACK feedback for the PDSCH reception using the downlink HARQ process;

[0096] For the downlink HARQ process, determine that the next received transport block is a first transmission or a new transmission.

[0097] When the HARQ process is a downlink HARQ process, for the DRX process, the terminal device may also start or restart the drx-RetransmissionTimerDL corresponding to the downlink HARQ process. The terminal device may also stop the drx-HARQ-RTT-TimerDL timer corresponding to the running downlink HARQ process. The terminal device may also stop the HARQ-RTT-offset-Timer corresponding to the running downlink HARQ process. The duration of the HARQ-RTT-offset-Timer is the start time offset of starting the drx-HARQ-RTT-TimerDL timer for the downlink HARQ process after the terminal device completes the NACK feedback for receiving the PDSCH using the downlink HARQ process.

[0098] In some embodiments, the number of HARQ processes may be one or multiple. That is, it may be that the attributes of one HARQ process change, and the MAC entity of the terminal device performs partial reset for this HARQ process; or it may be that the attributes of two or more HARQ processes change, and the MAC entity of the terminal device performs partial reset for each HARQ process whose attributes change.

[0099] The following is the detailed processing flow of the partial reset of the HARQ process by the MAC entity of the terminal device for the scenario where the attributes of the HARQ process change, as Figure 4 shown, including at least the following steps:

[0100] Step S301, the terminal device receives the RRC configuration information sent by the network device.

[0101] In some embodiments, the RRC configuration information may include: the relevant configurations of PDSCH and / or PUSCH. The relevant configurations of PDSCH and / or PUSCH may include: the uplink HARQ process configuration parameters and / or the downlink HARQ process configuration parameters; such as: the number of uplink HARQ processes, the number of downlink HARQ processes, the state of the HARQ function of each uplink HARQ process, the state of the HARQ function of each downlink HARQ process; wherein, the state of the HARQ function includes: enabling the HARQ feedback function or disabling the HARQ feedback function.

[0102] Step S302, the terminal device receives the first indication information sent by the network device.

[0103] In some embodiments, the terminal device receives first indication information sent by a network device through RRC signaling or DCI signaling; the first indication information is used to indicate that the feedback function of at least one HARQ process is switched from on to off or from off to on.

[0104] Step S303, the MAC entity of the terminal device resets the HARQ process whose feedback function status has changed.

[0105] In some embodiments, when the HARQ process is an uplink HARQ process, the MAC entity of the terminal device resetting the HARQ process includes at least one of the following:

[0106] Clear the buffer of the uplink HARQ process;

[0107] Stop the running drx-RetransmissionTimerUL corresponding to the uplink HARQ process;

[0108] Stop the running drx-HARQ-RTT-TimerUL corresponding to the uplink HARQ process;

[0109] Stop the running HARQ-RTT-offset-Timer corresponding to the uplink HARQ process, and the running duration of the HARQ-RTT-offset-Timer is the starting time offset of starting the drx-HARQ-RTT-TimerUL timer for the uplink HARQ process after the terminal device completes PUSCH transmission using the uplink HARQ process;

[0110] Stop the running configuredGrantTimer corresponding to the uplink HARQ process;

[0111] Configure the value of NDI of the uplink HARQ process to 0.

[0112] In other embodiments, when the HARQ process is a downlink HARQ process, the MAC entity of the terminal device resetting the HARQ process includes at least one of the following:

[0113] Clear the buffer of the downlink HARQ process;

[0114] Stop the running drx-RetransmissionTimerDL corresponding to the downlink HARQ process;

[0115] Stop the running drx-HARQ-RTT-TimerDL corresponding to the downlink HARQ process;

[0116] Stop the HARQ-RTT-offset-Timer corresponding to the running downlink HARQ process. The duration of the HARQ-RTT-offset-Timer is the starting time offset for starting the drx-HARQ-RTT-TimerDL for this downlink HARQ process after the terminal device completes the NACK feedback for receiving the PDSCH using this downlink HARQ process.

[0117] For the downlink HARQ process, determine whether the transport block received next time is a first transmission or a new transmission.

[0118] In the embodiments of the present application, when the attributes of the HARQ process change, the terminal device performing partial reset of the MAC entity can simplify the processing procedures of the terminal device and the network device, and avoid the transmission of the HARQ process still being processed complexly by the terminal device or the network device according to the configuration before the change of the attributes of the HARQ process when the attributes of the HARQ process change. Taking the example that the feedback function of the HARQ process is switched from enabled to disabled, the present application clarifies that at the moment when the feedback function of the HARQ process is switched, the terminal device does not need to feedback ACK / NACK for the downlink HARQ process, and for the data in the buffer of the uplink HARQ process, the terminal device does not need to wait for the response of the network device to receive the data. Taking the example that the feedback function of the HARQ process is switched from disabled to enabled, the present application clarifies that at the moment when the feedback function of the HARQ process is switched, the terminal device stops the running drx-HARQ-RTT-Timer, and considers the influence of the round-trip delay in subsequent transmissions, and only listens to the PDCCH after the drx-HARQ-RTT-Timer times out.

[0119] Another optional processing procedure of the information processing method provided by the embodiments of the present application is as Figure 5 shown, and at least includes the following steps:

[0120] Step S401, when the attributes of the HARQ process change, the terminal device starts or restarts the discontinuous reception retransmission timer corresponding to the HARQ process.

[0121] In some embodiments, the change of the attributes of the HARQ process includes: the feedback function of the HARQ process is switched from enabled to disabled; or, the feedback function of the HARQ process is switched from disabled to enabled.

[0122] In some embodiments, the method may further include:

[0123] Step S402, the terminal device stops the discontinuous reception hybrid automatic repeat request round-trip time timer corresponding to the HARQ process that is running.

[0124] In some embodiments, the method may further include:

[0125] Step S403, the terminal device stops the discontinuous reception hybrid automatic repeat request round-trip time offset timer corresponding to the HARQ process that is running.

[0126] In some embodiments, for an uplink HARQ process, when the attributes of the HARQ process change, the terminal device performs at least one of the following operations: starting or restarting drx-RetransmissionTimerUL; stopping the running drx-HARQ-RTT-TimerUL; stopping the running HARQ-RTT-offset timer, where the duration of the HARQ-RTT-offset timer is the start time offset of starting drx-HARQ-RTT-TimerUL for this uplink HARQ process after the terminal device completes PUSCH transmission using this uplink HARQ process.

[0127] In some embodiments, for a downlink HARQ process, when the attributes of the HARQ process change, the terminal device performs at least one of the following operations: starting or restarting drx-RetransmissionTimerDL corresponding to the downlink HARQ process; stopping the running drx-HARQ-RTT-TimerDL timer corresponding to the downlink HARQ process; stopping the running HARQ-RTT-offset-Timer corresponding to the downlink HARQ process, where the duration of the HARQ-RTT-offset-Timer is the start time offset of starting drx-HARQ-RTT-TimerDL for this downlink HARQ process after the terminal device completes NACK feedback for receiving PDSCH using this downlink HARQ process.

[0128] In some embodiments, the number of HARQ processes may be one or multiple.

[0129] Next, for a scenario where the attributes of the HARQ process change, an optional processing flow for the terminal device to perform DRX processing is as follows: Figure 6 shown, and at least includes the following steps:

[0130] Step S501, the terminal device receives RRC configuration information sent by the network device.

[0131] In some embodiments, the RRC configuration information may include: parameters related to DRX; the parameters related to DRX may include: DRX cycle, drx-onDurationTimer, drx-InactivityTimer, drx-HARQ-RTT-TimerDL, drx-RetransmissionTimerDL, drx-HARQ-RTT-TimerUL, and drx-RetransmissionTimerUL, etc.,

[0132] The RRC configuration information may further include: the related configurations of PDSCH and / or PUSCH. The related configurations of PDSCH and / or PUSCH may include: uplink HARQ process configuration parameters and / or downlink HARQ process configuration parameters; such as: the number of uplink HARQ processes, the number of downlink HARQ processes, the state of the HARQ function of each uplink HARQ process, the state of the HARQ function of each downlink HARQ process; wherein, the state of the HARQ function includes: enabling the HARQ feedback function or disabling the HARQ feedback function.

[0133] Step S502, the terminal device receives the first indication information sent by the network device.

[0134] In some embodiments, the terminal device receives the first indication information sent by the network device through RRC signaling or DCI signaling; the first indication information is used to indicate that the feedback function of at least one HARQ process is switched from enabled to disabled or from disabled to enabled.

[0135] Step S503, the terminal device performs DRX processing on the HARQ process whose feedback function state has changed.

[0136] In some embodiments, when the HARQ process is an uplink HARQ process, the terminal device starts or restarts drx-RetransmissionTimerUL; the terminal device stops the running drx-HARQ-RTT-TimerUL; the terminal device stops the running HARQ-RTT-offset timer, and the duration of the HARQ-RTT-offset timer is the start time offset when the terminal device starts drx-HARQ-RTT-TimerUL for this uplink HARQ process after completing the PUSCH transmission using this uplink HARQ process.

[0137] Taking the example that the HARQ feedback function of the uplink HARQ process corresponding to HARQ ID 0 is switched from enabled to disabled, a detailed processing flow of the terminal device for DRX processing is as follows Figure 7As shown in the figure, when the terminal device receives an indication to turn off the HARQ feedback function, it stops the drx-HARQ-RTT-TimerUL corresponding to HARQ ID 0, starts the drx-RetransmissionTimerUL corresponding to HARQ ID 0, and stops the HARQ-RTT-offset timer that is currently running and corresponding to HARQ ID 0.

[0138] In some embodiments, when the HARQ process is a downlink HARQ process, the terminal device starts or restarts the drx-RetransmissionTimerDL corresponding to the downlink HARQ process; the terminal device stops the drx-HARQ-RTT-TimerDL timer that is currently running and corresponding to the downlink HARQ process; the terminal device stops the HARQ-RTT-offset-Timer that is currently running and corresponding to the downlink HARQ process, and the duration of the HARQ-RTT-offset-Timer is the start time offset of starting the drx-HARQ-RTT-TimerDL timer for this downlink HARQ process after the terminal device completes the NACK feedback for receiving the PDSCH using this downlink HARQ process.

[0139] Taking the example that the HARQ feedback function of the downlink HARQ process corresponding to HARQ ID 1 is switched from on to off, another detailed processing flow of the terminal device for DRX processing is as Figure 8 As shown in the figure, when the terminal device receives an indication to turn off the HARQ feedback function, it stops the drx-HARQ-RTT-TimerDL corresponding to HARQ ID 1, starts the drx-RetransmissionTimerDL corresponding to HARQ ID 1, and stops the HARQ-RTT-offset timer that is currently running and corresponding to HARQ ID 1.

[0140] In the embodiments of the present application, when the attribute of the HARQ process changes, starting or restarting the DRX retransmission timer can enable the terminal device and the network device to start processing the transmission and reception of new PDCCHs from a determined moment, and avoid complex processing of DRX monitoring before the attribute of the HARQ process changes.

[0141] The above embodiments respectively describe the processing flow for resetting the MAC entity of the terminal device and the DRX processing flow when the attribute of the HARQ process changes; in specific implementation, for the scenario where the attribute of the HARQ process changes, the terminal device can both reset the MAC entity and perform DRX processing; that is, the steps of the information processing method shown above and Figure 3 shown in Figure 5The steps of the information processing method shown can be executed simultaneously.
