Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a timer state changing method, device, terminal and storage medium. Background Art

[0002] In the fifth-generation mobile communication (5G) network, a DRX (Discontinuous Reception) mechanism is introduced based on energy saving considerations.

[0003] For UEs with the DRX mechanism, the DRX timer can be used to trigger the UE to enter sleep mode (Sleep Mode) during certain time periods and not monitor PDCCH subframes. When the DRX timer determines that the terminal is in a time period that requires monitoring, the UE is awakened from the sleep mode, thereby reducing the power consumption generated by the UE monitoring the PDCCH.

[0004] In the above solution, the UE may be awakened by the DRX timer during a period when it does not need to monitor the PDCCH, resulting in unnecessary power consumption. Summary of the Invention

[0005] The present invention provides a method, device, terminal, and storage medium for changing a timer state. The technical solution is as follows:

[0006] In one aspect, an embodiment of the present application provides a method for changing a timer state, the method comprising:

[0007] During the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process of the terminal, if the transmission of the terminal meets the first condition, the operation state of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is changed.

[0008] In another aspect, an embodiment of the present application provides a method for changing a timer state, the method comprising:

[0009] During the operation of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process of the terminal, if the transmission of the terminal meets the second condition, the operation state of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is changed.

[0010] In another aspect, an embodiment of the present application provides a device for changing a timer state, the device comprising:

[0011] The first timer changing module changes the running state of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process of the device during the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process when the transmission of the device meets the first condition.

[0012] In another aspect, an embodiment of the present application provides a device for changing a timer state, the device comprising:

[0013] The second timer changing module is used to change the running state of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process of the device during the operation of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process when the transmission with the device meets the second condition.

[0014] On the other hand, an embodiment of the present application provides a terminal, which includes a processor, a memory and a transceiver, wherein the memory stores a computer program, and the computer program is used to be executed by the processor to implement the above-mentioned timer state change method.

[0015] On the other hand, an embodiment of the present application further provides a computer-readable storage medium, in which a computer program is stored. The computer program is loaded and executed by a processor to implement the above-mentioned timer state changing method.

[0016] In another aspect, a computer program product or computer program is provided, the computer program product or computer program including computer instructions stored in a computer-readable storage medium. A processor of a terminal reads the computer instructions from the computer-readable storage medium and executes the computer instructions, causing the terminal to perform the above-described timer state change method.

[0017] The technical solutions provided in the embodiments of the present application can bring the following beneficial effects:

[0018] When the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process of the terminal is running and the transmission process of the terminal meets the first condition, the network side device may not send PDCCH to the terminal within a period of time when the uplink transmission occurs. The terminal does not need to monitor the PDCCH at this time. Therefore, the terminal can change the running status of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, such as stopping or restarting to reasonably extend the next timeout time of RTT, thereby reducing unnecessary monitoring of the terminal due to DRX-HARQ-RTT-Timer timeout, reducing the power consumption of the terminal, and saving the power of the terminal.

[0036] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0037] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. A person skilled in the art will appreciate that, with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0038] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0039] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0040] In the embodiments of the present application, "predefined" can be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in devices (for example, including terminal devices and network-side devices). The present application does not limit the specific implementation method. For example, predefined can refer to information defined in the protocol.

[0041] Figure 1A schematic diagram of a network architecture of a communication system provided by an embodiment of the present application is shown. The network architecture may include: a terminal 10, a base station 20, and a core network 30.

[0042] There are usually multiple terminals 10, and one or more terminals 10 can be distributed in the cell managed by each base station 20. The terminals 10 can include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), terminal devices, etc. For ease of description, in the embodiments of the present application, the above-mentioned devices are collectively referred to as terminals.

[0043] The base station 20 is a device deployed in the access network to provide wireless communication functions for the terminal 20. The base station 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with base station functions may be different. For example, in the 5G New Radio (NR) system, it is called gNodeB or gNB. With the evolution of communication technology, the name "base station" may change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal 20 are collectively referred to as base stations.

[0044] In the embodiment of the present application, the base station 20 may include at least two base stations, and the at least two base stations are respectively used to cover the cells corresponding to the base stations.

[0045] The Core Network (CN) 30 primarily provides user connections, user management, and service delivery, acting as a bearer network interface to external networks. User connection establishment includes functions such as mobility management, call management, switching / routing, and recording notifications (combined with intelligent network services to connect to intelligent network peripheral devices).

[0046] Optional, Figure 1 What is not shown is that the above network architecture also includes other network-side devices, such as: a central control node (CNC), a session management function (SMF) or a user plane function (UPF) device, etc.

[0047] The "5G NR system" in the embodiments of this disclosure may also be referred to as a 5G system or an NR system, but those skilled in the art will understand the meaning. The technical solutions described in the embodiments of this disclosure are applicable to the 5G NR system and to subsequent evolution systems of the 5G NR system.

[0048] Currently, with the increasing demand for speed, latency, high-speed mobility, and energy efficiency, coupled with the increasing diversity and complexity of future services, the 3GPP international standards organization has begun developing 5G. The main application scenarios for 5G are: eMBB (Enhanced Mobile Broadband), URLLC (Ultra Reliable Low Latency Communication), and mMTC (Massive Machine Type Communication).

[0049] eMBB still aims to provide users with multimedia content, services, and data, and demand for this technology is growing rapidly. However, since eMBB can be deployed in diverse scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary significantly. Therefore, it cannot be generalized and requires detailed analysis based on specific deployment scenarios. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety. Typical characteristics of mMTC include high connection density, small data volumes, latency-insensitive services, low module costs, and long service life.

[0050] NR can also be deployed independently. In order to reduce air interface signaling and quickly restore wireless connections and data services in the 5G network environment, a new RRC state is defined, namely the RRC_INACTIVE state. This state is different from the RRC_IDLE and RRC_ACTIVE states.

[0051] RRC_IDLE (Idle): Mobility is based on UE cell selection and reselection. Paging is initiated by the CN, and the paging area is configured by the CN. There is no UE AS context on the base station side. There is no RRC connection.

[0052] RRC_CONNECTED (Connected state): An RRC connection exists, and a UE AS context exists between the base station and the UE. The network knows the UE's location at the cell level. Mobility is controlled by the network. Unicast data can be transmitted between the UE and the base station.

[0053] RRC_INACTIVE (inactive state): mobility is based on UE cell selection and reselection, there is a connection between CN and NR, the UE AS context exists on a certain base station, paging is triggered by RAN (Radio Access Network), and the RAN-based paging area is managed by RAN. The network side knows the UE location based on the RAN paging area level.

[0054] In 5G NR, the network can configure the DRX (Discontinuous Reception) function for the terminal, so that the terminal can monitor the PDCCH discontinuously to achieve the purpose of terminal power saving. Figure 2 FIG. 1 shows a schematic diagram of a DRX cycle of a terminal. Figure 2 As shown, in a DRX cycle, when the terminal is determined to be in the wake-up period of the DRX cycle, the terminal is allowed to monitor the PDCCH; when the terminal is determined to be in the sleep period of the DRX cycle, the terminal does not monitor the PDCCH.

[0055] Each MAC entity has a DRX configuration. The DRX configuration parameters include:

[0056] - DRX-onDurationTimer: Duration when the DRX cycle starts.

[0057] - DRX-SlotOffset: The delay before the start of the DRX cycle.

[0058] - DRX-InactivityTimer: Indicates the duration after the PDCCH opportunity where the PDCCH is located for the MAC entity to make new UL or DL ​​transmissions.

[0059] - DRX-RetransmissionTimerDL: Maximum duration before receiving a downlink HARQ (Hybrid Automatic Repeat Request) retransmission grant.

[0060] - DRX-RetransmissionTimerUL: Maximum duration before receiving an uplink HARQ retransmission grant.

[0061] - DRX-LongCycleStartOffset: Long DRX, and the delay between the start of the long DRX cycle and the short DRX cycle.

[0062] - DRX-ShortCycle (optional): short DRX cycle.

[0063] - DRX-ShortCycleTimer (optional): Duration of the short DRX cycle followed by the UE.

[0064] - DRX-HARQ-RTT-TimerDL: The minimum duration of a downlink grant before the UE receives an indication of a downlink HARQ retransmission.

[0065] - DRX-HARQ-RTT-TimerUL: Minimum duration before the UE receives an uplink grant indicating an uplink HARQ retransmission.

[0066] If the terminal is configured with DRX, it needs to monitor the PDCCH during the DRX activation period. The DRX activation period includes the following situations:

[0067] (1) Any of the five timers, DRX-onDurationTimer, DRX-InactivityTimer, DRX-RetransmissionTimerDL, DRX-RetransmissionTimerUL, and ra-ContentionResolutionTimer, is running.

[0068] (2) An SR is sent on the PUCCH and is in the pending state.

[0069] (3) In a contention-based random access procedure, the terminal has not received an initial transmission indicated by a C-RNTI-scrambled PDCCH after successfully receiving a random access response.

[0070] The terminal determines when to start the DRX-onDurationTimer based on whether it is currently in a long DRX cycle or a short DRX cycle. The specific regulations are as follows:

[0071] If a short DRX cycle is used and the current subframe satisfies [(SFN×10)+subframe number]modulo(DRX-ShortCycle)=(DRX-StartOffset)modulo(DRX-ShortCycle); or if a long DRX cycle is used and the current subframe satisfies [(SFN×10)+subframe number]modulo(DRX-LongCycle)=DRX-StartOffset, where SFN refers to the system frame number.

[0072] Start DRX-onDurationTimer at the moment DRX-SlotOffset slots after the start of the current subframe.

[0073] The conditions for the terminal to start or restart the DRX-InactivityTimer are:

[0074] If the terminal receives a PDCCH indicating downlink or uplink initial transmission, the terminal starts or restarts the DRX-Inactivity Timer.

[0075] The conditions for the terminal to start and stop DRX-RetransmissionTimerDL are:

[0076] When the terminal receives a PDCCH indicating a downlink transmission, or when the terminal receives a MAC PDU on the configured downlink grant resources, the terminal stops the DRX-RetransmissionTimerDL corresponding to the HARQ process. The terminal starts the DRX-HARQ-RTT-TimerDL corresponding to the HARQ process after completing the transmission of the HARQ process feedback for this downlink transmission.

[0077] If the timer DRX-HARQ-RTT-TimerDL corresponding to a certain HARQ process of the terminal times out and the downlink data transmitted using this HARQ process is not decoded successfully, the terminal starts the DRX-RetransmissionTimerDL corresponding to this HARQ process.

[0078] The conditions for the terminal to start and stop DRX-RetransmissionTimerUL are:

[0079] When the terminal receives a PDCCH indicating an uplink transmission, or when the terminal sends a MAC PDU on the configured uplink grant resources, the terminal stops the DRX-RetransmissionTimerUL corresponding to the HARQ process. The terminal starts the DRX-HARQ-RTT-TimerUL corresponding to the HARQ process after completing the first repetition of the PUSCH.

[0080] If the timer DRX-HARQ-RTT-TimerUL corresponding to a certain HARQ process of the terminal times out, the terminal starts the DRX-RetransmissionTimerUL corresponding to this HARQ process.

[0081] In the current DRX mechanism, drx-HARQ-RTT-TimerUL / drx-HARQ-RTT-TimerDL and RetransmissionTimerUL / RetransmissionTimerDL are maintained for each UL / DL HARQ process. drx-HARQ-RTT-TimerUL and drx-HARQ-RTT-TimerDL are the minimum time intervals that a UE expects to schedule retransmissions for the corresponding HARQ process. Furthermore, for UEs configured for DRX, they monitor the PDCCH during the DRX Active Time. Therefore, one understanding of drx-HARQ-RTT-TimerUL and drx-HARQ-RTT-TimerDL is that during the operation of drx-HARQ-RTT-TimerUL (if HARQ process i is an uplink HARQ process) or drx-HARQ-RTT-TimerDL (if HARQ process i is a downlink HARQ process) of a certain HARQ process i, if the UE is currently in DRX Active Time due to other reasons (such as RetransmissionTimerUL / RetransmissionTimerDL of other HARQ processes are running, or drx-InactivityTimer is running, etc.), since the UE's behavior is to monitor PDCCH, the network can still schedule retransmission of HARQ process i during this period. In other words, the UE may still receive the network's PDCCH scheduling the HARQ process during the operation of the HARQ RTT timer corresponding to HARQ process i. Based on the current protocol description, taking the above behavior as an example, if the UE receives a PDCCH indicating an uplink transmission, the UE stops the RetransmissionTimerUL corresponding to the HARQ process and starts the drx-HARQ-RTT-TimerUL corresponding to the HARQ process in the first symbol after the terminal completes the first repetition of the PUSCH. If the UE receives the PDCCH while the drx-HARQ-RTT-TimerUL of the HARQ process is running, the RetransmissionTimerUL may be started before the UE sends the PUSCH due to the expiration of the drx-HARQ-RTT-TimerUL, resulting in additional power consumption of the UE.

[0082] The above HARQ process i is hereinafter represented by the first uplink / downlink HARQ process.

[0083] The embodiments of the present application are based on the DRX mechanism and provide a feasible solution for controlling a terminal to monitor the downlink physical control channel (PDCCH) by determining the status of the terminal's DRX timer in the RRC connected state. In this application, DRX and DRX are both abbreviations for discontinuous reception (DRX), and their meanings are the same.

[0084] Figure 3 A flowchart of a method for changing a timer state provided by an embodiment of the present application is shown. The method can be executed by a terminal, wherein the terminal can be Figure 1 The terminal 10 in the network architecture shown. The method may include the following steps:

[0085] Step 301: During the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process of the terminal, if the transmission of the terminal meets the first condition, change the operation state of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process.

[0086] In a possible implementation, the first condition includes: the terminal transmitting the first MAC PDU during the running period of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, wherein the first uplink HARQ process is any uplink HARQ process of the terminal.

[0087] In one possible implementation, when the terminal transmits a first MAC PDU during the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, the operation state of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is changed. The first MAC PDU is a MAC PDU transmitted using the first uplink HARQ process.

[0088] When the terminal uses the first uplink HARQ process to transmit the first MAC PDU, since the network side device will not send corresponding indication information through PDCCH within a certain period of time after the terminal transmits the first MAC PDU through the first uplink HARQ process, the terminal does not need to monitor the PDCCH within a certain period of time. At this time, the terminal can update the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process to avoid monitoring the PDCCH due to the timeout of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process.

[0089] In one possible implementation, during the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, the terminal performs N repeated transmissions of the first MAC PDU on the PUSCH through CG authorization-free transmission, and when no listen-before-talk (LBT) failure indication sent by the physical layer is received, the operation status of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is adjusted and changed.

[0090] The terminal can transmit the first MAC PDU through CG authorization-free and at least one bundled data transmission during the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process. When the terminal does not receive the listen-before-talk LBT failure indication sent by the physical layer, it means that the terminal has successfully sent the channel to the PUSCH. At this time, the terminal can change the operating status of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process to delay the PDCCH monitoring and avoid unnecessary power consumption.

[0091] In a possible implementation, when the first uplink HARQ process is used to perform the first repeated transmission of the PUSCH transmission corresponding to the first MAC PDU, the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is stopped.

[0092] In a possible implementation, at the first time symbol after the first repeated transmission of the PUSCH transmission corresponding to the first MAC PDU is completed using the first uplink HARQ process, the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is started or restarted.

[0093] In a possible implementation, during the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, when the terminal receives a PDCCH indicating to use the first uplink HARQ process to transmit the first MAC PDU, the operation state of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is changed.

[0094] The terminal can also receive the first indication information sent by the network side device through PDCCH during the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process and perform N data transmissions to transmit the first MAC PDU. At this time, during the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, the terminal still receives the first indication information sent by the network side device through PDCCH through other HARQs, and performs N data transmissions to transmit the first MAC PDU according to the first indication information. The operating state of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is changed to delay monitoring of the first HARQ to avoid unnecessary power consumption.

[0095] In a possible implementation, when the terminal receives the PDCCH, the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is stopped.

[0096] In a possible implementation, at the first time symbol after the first repeated transmission of the PUSCH transmission corresponding to the first MAC PDU is completed using the first uplink HARQ process, the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is started.

[0097] In a possible implementation manner, when the terminal receives the PDCCH indicating to use the first uplink HARQ process to transmit the first MAC PDU, the terminal stops the first RetransmissionTimerDL corresponding to the first uplink HARQ process.

[0098] To sum up, in the scheme shown in the embodiment of the present application, when the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process of the terminal is running and the transmission process of the terminal meets the first condition, the network side device may not send PDCCH to the terminal within a period of time when the uplink transmission occurs. The terminal does not need to monitor the PDCCH at this time. Therefore, the terminal can change the running status of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, such as by stopping or restarting to reasonably extend the next timeout time of RTT, thereby reducing unnecessary monitoring of the terminal due to DRX-HARQ-RTT-Timer timeout, reducing the power consumption of the terminal, and saving the power of the terminal.

[0099] Figure 4 A flowchart of a timer status change method provided by an embodiment of the present application is shown. The method can be executed by a terminal and a network side device, wherein the terminal can be Figure 1 In the terminal 10 of the network architecture shown, the network side device can be Figure 1 The base station 20 in the network architecture shown. The method may include the following steps:

[0100] Step 401: Determine DRX configuration parameters corresponding to the terminal according to first configuration information.

[0101] The DRX configuration parameter is used to configure each DRX timer corresponding to the terminal.

[0102] In a possible implementation, the first configuration information is sent to the terminal by a network-side device through downlink signaling.

[0103] In another possible implementation manner, the first configuration information may be pre-stored in the terminal.

[0104] That is, the terminal may first configure the DRX timer of the terminal according to the first configuration information pre-stored in the terminal.

[0105] In one possible implementation, the first configuration information is further used to indicate the number of HARQ processes of the terminal. When the number of HARQ processes of the terminal is greater than or equal to 2, the terminal can configure multiple HARQ processes according to the first configuration information to implement data transmission with the network side device.

[0106] Step 402: During the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process of the terminal, if the transmission with the terminal meets the first condition, change the operation state of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process.

[0107] The first uplink HARQ process is any one of the uplink HARQ processes of the terminal.

[0108] In one possible implementation, when the first uplink HARQ process meets the first condition, the terminal can change the running state of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, so that the terminal can update the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process according to the operation performed by the first uplink HARQ process, so that the timing function of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is more accurate, avoiding the situation where the terminal monitors the PDCCH channel at unnecessary times due to the timeout of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, reducing the power consumption of the terminal, saving the battery power of the terminal, and extending the battery life of the terminal.

[0109] In one possible implementation, when the terminal transmits a first MAC PDU during the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, the operation state of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is changed. The first MAC PDU is a MAC PDU corresponding to the first HARQ.

[0110] The first uplink HARQ process satisfies the first condition that the terminal transmits the first MAC PDU during the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process. At this time, when the terminal uses the first uplink HARQ process to transmit the first MAC PDU, the operation state of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process can be changed to ensure that the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process corresponds to the current transmission state of the first uplink HARQ process, thereby avoiding the terminal from performing monitoring at unnecessary times.

[0111] In one possible implementation, during the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, the terminal performs N repeated transmissions of the first MAC PDU on the PUSCH through CG authorization-free transmission, and changes the operating status of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process when no listen-before-talk LBT failure indication sent by the physical layer is received.

[0112] The terminal can use the first uplink HARQ process to perform N repeated transmissions of the first MAC PDU on the PUSCH through CG authorization exemption. When the terminal performs N repeated transmissions of the first MAC PDU on the PUSCH through CG authorization exemption, and the terminal does not receive the listen-before-talk LBT failure indication sent by the physical layer, it means that the terminal has successfully sent the first MAC PDU, and at this time the terminal is in the operation period of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process. In order to ensure that the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process corresponds to the transmission state of the current first uplink HARQ process, the operation state of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process can be changed.

[0113] In a possible implementation, when the first uplink HARQ process is used to perform the first repeated transmission of the PUSCH transmission corresponding to the first MAC PDU, the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is stopped.

[0114] When the terminal uses the first uplink HARQ process to perform the first repeated transmission of the PUSCH transmission corresponding to the first MAC PDU through CG authorization exemption, the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is stopped. When the terminal performs the first repeated transmission of the PUSCH transmission corresponding to the first MAC PDU, the terminal uses the first uplink HARQ process to upload data. At this time, after the network side device receives the data uploaded using the first uplink HARQ process, it will not send signaling through the PDCCH in a short time. Therefore, the terminal can first stop the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process to avoid unnecessary power consumption.

[0115] In a possible implementation, at the first time symbol after the first repeated transmission of the PUSCH transmission corresponding to the first MAC PDU is completed using the first uplink HARQ process, the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is started.

[0116] When the terminal uses the first uplink HARQ process to complete the first time symbol after the first repeated transmission of the PUSCH transmission corresponding to the first MAC PDU through CG authorization-free, the terminal has completed the first repeated transmission to the network side device using the first uplink HARQ process, and the network side device has also completed the action of receiving the data of the first repeated transmission. At this time, the DRX-HARQ-RTT-TimerUL corresponding to the stopped first uplink HARQ process can be restarted, so that when the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process re-runs to timeout, the terminal monitors PDCCH.

[0117] In a possible implementation, at the first time symbol after the first repeated transmission of the PUSCH transmission corresponding to the first MAC PDU is completed using the first uplink HARQ process, the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is started or restarted.

[0118] When the terminal uses the first uplink HARQ process to complete the first time symbol after the first repeated transmission of the PUSCH transmission corresponding to the first MAC PDU through CG authorization-free, the terminal has completed the first repeated transmission to the network side device using the first uplink HARQ process, and the network side device has also completed the action of receiving the data of the first repeated transmission. When the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is in a stopped state at this time, it can be turned on so that the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is restarted and runs until the timeout, and the terminal monitors PDCCH; when the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is in a running state, the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process in the running state can be restarted so that when the terminal uses the first uplink HARQ process to complete the first MAC After the first repeated transmission of the PUSCH transmission corresponding to the PDU, the terminal restarts the timing of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process.

[0119] Figure 5 FIG. 1 shows a timing diagram of a method for changing a timer state according to an embodiment of the present application. Figure 5As shown, it shows the first repeated transmission of the PUSCH transmission corresponding to the first MAC PDU in the CG (Configured Grant, unauthorized transmission), and during the first repeated transmission, the terminal 501 uploads the first MAC PDU to the network side device. When the terminal 501 starts to upload the first MAC PDU to the network side device 502, and the first RetransmissionTimerUL is running at this time, the terminal can stop the first RetransmissionTimerUL, and at the first time symbol after the first MAC PDU is uploaded, the terminal starts the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process; when the terminal 501 starts to upload the first MAC PDU to the network side device 502, and the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is running, the terminal can stop the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, and at the first time symbol after the first MAC PDU is uploaded, the terminal starts the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process.

[0120] Figure 6 FIG. 1 shows a timing diagram of a method for changing a timer state according to an embodiment of the present application. Figure 6 As shown, it shows the first repeated transmission of the PUSCH transmission corresponding to the first MAC PDU in the CG unauthorized transmission, and during the first repeated transmission, the terminal 601 uploads the first MAC PDU to the network side device. When the terminal 601 starts to upload the first MAC PDU to the network side device 602, and the first RetransmissionTimerUL is running, the terminal can stop the first RetransmissionTimerUL and start the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process at the first time symbol after the upload of the first MAC PDU is completed; when the terminal 601 starts to upload the first MAC PDU to the network side device 602, and the terminal is in the state where the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is running, the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process can be restarted at the first time symbol after the upload of the first MAC PDU is completed.

[0121] In a possible implementation, during the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, when the terminal receives a PDCCH indicating to use the first uplink HARQ process to transmit the first MAC PDU, the operation state of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is changed.

[0122] At this time, the first condition includes: during the operation of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, the terminal receives a PDCCH indicating that the first uplink HARQ process is used to transmit the first MAC PDU. At this time, when the first uplink HARQ process transmits the first MAC PDU according to the instruction of the PDCCH, the operation state of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process can be changed to ensure that the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process corresponds to the transmission state of the current first uplink HARQ process, thereby avoiding the first uplink HARQ process from monitoring resources at unnecessary times, reducing the power consumption of the terminal, saving the battery power of the terminal, and extending the battery life of the terminal.

[0123] In a possible implementation, when the terminal receives the PDCCH, the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is stopped.

[0124] When the terminal receives the PDCCH and the PDCCH indicates the use of the first uplink HARQ process to transmit the first MAC PDU, the terminal can schedule the first uplink HARQ process to perform the operation of transmitting the first MAC PDU according to the instruction of the PDCCH, that is, when the terminal receives the PDCCH, the terminal uses the first uplink HARQ process to start the operation of transmitting the first MAC PDU. At this time, if the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is operating normally, the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process can be stopped to avoid the situation where the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process times out and causes the terminal to monitor resources at unnecessary times.

[0125] In a possible implementation, at the first time symbol after the first repeated transmission of the PUSCH transmission corresponding to the first MAC PDU is completed using the first uplink HARQ process, the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is started.

[0126] When the terminal uses the first uplink HARQ process and receives the first time symbol after the first repeated transmission of the PUSCH transmission corresponding to the first MAC PDU indicated by the PDCCH, the terminal has completed the first repeated transmission to the network side device using the first uplink HARQ process, and the network side device has also completed the action of receiving the data of the first repeated transmission. At this time, the terminal can restart the DRX-HARQ-RTT-TimerUL corresponding to the stopped first uplink HARQ process, so that the terminal controls the PDCCH monitoring corresponding to the first uplink HARQ process according to the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process.

[0127] In a possible implementation manner, when the terminal receives the PDCCH indicating to use the first uplink HARQ process to transmit the first MAC PDU, the terminal stops the first RetransmissionTimerDL corresponding to the first uplink HARQ process.

[0128] Figure 7 FIG. 1 shows a timing diagram of a method for changing a timer state according to an embodiment of the present application. Figure 7 As shown, it shows that the network side device 702 sends the first indication information to the terminal 701 on the PDCCH, and after the terminal 701 receives the first indication information, it can start to transmit the first MAC PDU corresponding to the first indication information to the network side device 702. When the terminal 701 receives the first indication information sent by the network side device 702 to the terminal in PDCCH, and the first RetransmissionTimerUL is running at this time, the terminal can stop the first RetransmissionTimerUL and start the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process at the first time symbol after the first MAC PDU is uploaded; when the terminal 701 receives the first indication information sent by the network side device 702 to the terminal in PDCCH, and the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is running at this time, the terminal can stop the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process at the moment when the terminal 701 receives the PDCCH, and start the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process at the first time symbol after the first MAC PDU is uploaded.

[0129] Figure 8 This is a timing diagram of a timer state changing method involved in an embodiment of the present application. Figure 8FIG. 2 shows a state change of a DRX timer by the terminal when the terminal receives a PDCCH and performs data retransmission according to the PDCCH.

[0130] At time t1, when the terminal receives the PDCCH and the drx-RetransmissionTimerUL corresponding to the first uplink HARQ process is in the started state, the terminal turns off the drx-RetransmissionTimerUL timer corresponding to the first uplink HARQ process; or, when the terminal receives the PDCCH and the drx-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process is in the started state, the terminal stops the drx-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process.

[0131] At time t2, after the terminal completes the first repeated transmission of the first MAC PDU in a bundle using the first uplink HARQ process, the terminal starts the drx-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process.

[0132] When the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process of the terminal is running and the transmission process of the terminal meets the first condition, the network side device may not send PDCCH to the terminal within a period of time when the uplink transmission occurs. The terminal does not need to monitor the PDCCH at this time. Therefore, the terminal can change the running status of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, such as stopping or restarting to reasonably extend the next timeout time of RTT, thereby reducing unnecessary monitoring of the terminal due to DRX-HARQ-RTT-Timer timeout, reducing the power consumption of the terminal, and saving the power of the terminal.

[0133] To sum up, in the scheme shown in the embodiment of the present application, when the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process of the terminal is running and the transmission process of the terminal meets the first condition, the network side device may not send PDCCH to the terminal within a period of time when the uplink transmission occurs. The terminal does not need to monitor the PDCCH at this time. Therefore, the terminal can change the running status of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, such as by stopping or restarting to reasonably extend the next timeout time of RTT, thereby reducing unnecessary monitoring of the terminal due to DRX-HARQ-RTT-Timer timeout, reducing the power consumption of the terminal, and saving the power of the terminal.

[0134] Figure 9A flowchart of a method for changing a timer state provided by an embodiment of the present application is shown. The method can be executed by a terminal, wherein the terminal can be Figure 1 The terminal 10 in the network architecture shown. The method may include the following steps:

[0135] Step 901: During the operation of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process of the terminal, if the transmission with the terminal meets the second condition, change the operation state of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process.

[0136] The first downlink HARQ process is any one of the downlink HARQ processes of the terminal.

[0137] In one possible implementation, when the terminal receives a second MAC PDU during the operation of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process, the operation state of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is changed; wherein the second MAC PDU is a MAC PDU transmitted using the first downlink HARQ process.

[0138] When the terminal uses the first downlink HARQ process to receive the first MAC PDU, the network side device will not send corresponding indication information through PDCCH within a certain period of time after the terminal receives the first MAC PDU. Therefore, the terminal does not need to monitor PDCCH within a certain period of time. At this time, the terminal can update the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process to avoid the terminal monitoring PDCCH at unnecessary times due to the timeout of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process.

[0139] In one possible implementation, when the terminal receives the second MAC PDU on the PDSCH through SPS semi-persistent scheduling during the operation of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process, the operation state of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is changed.

[0140] Among them, SPS (Semi-Persistent Scheduling) means that after the terminal applies for resources from the network side device once, the corresponding resources are periodically allocated to the terminal within a period of time. Therefore, the terminal can periodically receive the MAC PDU on the PDSCH through SPS semi-persistent scheduling. When the terminal receives the second MAC PDU on the PDSCH through SPS semi-persistent scheduling during the operation of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process, the terminal can change the operation state of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process according to the behavior of the first downlink HARQ process receiving the second MAC PDU, so that the first downlink HARQ process delays monitoring to avoid unnecessary power consumption.

[0141] In a possible implementation, when the second MAC PDU is received in the PDSCH using the first downlink HARQ process, the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is stopped.

[0142] In one possible implementation, during the operation of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process, when the terminal receives a PDCCH indicating to use the first downlink HARQ process to receive the second MAC PDU, the operation status of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is changed.

[0143] The terminal can also receive the second indication information sent by the network side device through PDCCH during the operation of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process, instructing the use of the first downlink HARQ process to receive the second MAC PDU. At this time, the first downlink HARQ process still uses other HARQs to receive the second indication information sent by the network side device through PDCCH during the operation of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process, and instructs the use of the first downlink HARQ process to receive the second MAC PDU according to the second indication information. At this time, according to the behavior of the first downlink HARQ process receiving the second MAC PDU, the operation state of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process can be changed, so that the first downlink HARQ process delays monitoring to avoid unnecessary power waste.

[0144] In a possible implementation manner, when the terminal receives the PDCCH, the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is stopped.

[0145] In a possible implementation, at the first time symbol after the first downlink HARQ process completes transmission of feedback for receiving the second MAC PDU, the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is started.

[0146] In a possible implementation, when the terminal receives the PDCCH indicating to use the first downlink HARQ process to receive the second MAC PDU, the terminal stops the first RetransmissionTimerDL corresponding to the first downlink HARQ process.

[0147] To sum up, in the scheme shown in the embodiment of the present application, when the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process of the terminal is running and the transmission process of the terminal meets the first condition, the network side device may not send PDCCH to the terminal within a period of time when the uplink transmission occurs. The terminal does not need to monitor the PDCCH at this time. Therefore, the terminal can change the running status of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, such as by stopping or restarting to reasonably extend the next timeout time of RTT, thereby reducing unnecessary monitoring of the terminal due to DRX-HARQ-RTT-Timer timeout, reducing the power consumption of the terminal, and saving the power of the terminal.

[0148] Figure 10 A flowchart of a timer status change method provided by an embodiment of the present application is shown. The method can be executed by a terminal and a network side device, wherein the terminal can be Figure 1 In the terminal 10 of the network architecture shown, the network side device can be Figure 1 The base station 20 in the network architecture shown. The method may include the following steps:

[0149] Step 1001: Determine DRX configuration parameters corresponding to the terminal according to first configuration information.

[0150] The DRX configuration parameter is used to configure each DRX timer corresponding to the terminal.

[0151] In a possible implementation, the first configuration information is sent to the terminal by a network-side device through downlink signaling.

[0152] In another possible implementation manner, the first configuration information may be pre-stored in the terminal.

[0153] That is, the terminal may first configure the DRX timer of the terminal according to the first configuration information pre-stored in the terminal.

[0154] In one possible implementation, the first configuration information is further used to indicate the number of HARQ processes of the terminal. When the number of HARQ processes of the terminal is greater than or equal to 2, the terminal can configure multiple HARQ processes according to the first configuration information to implement data transmission with the network side device.

[0155] Step 1002: If the first downlink HARQ process satisfies the second condition, the running state of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is changed, wherein the first downlink HARQ process is any one of the HARQ processes of the terminal.

[0156] When the first downlink HARQ process meets the second condition, the terminal can change the running status of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process, so that the terminal can update the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process according to the transmission operation performed using the first downlink HARQ process, so that the timing function of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is more accurate, avoiding the terminal from monitoring the PDCCH channel at unnecessary times due to the timeout of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process, reducing the power consumption of the terminal, saving the terminal's battery life, and extending the terminal's battery life.

[0157] In one possible implementation, when the terminal receives a second MAC PDU during the operation of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process, the operation state of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is changed; wherein the second MAC PDU is a MAC PDU transmitted using the first downlink HARQ process.

[0158] Among them, the first downlink HARQ process satisfies the second condition that the terminal receives the second MAC PDU during the operation of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process. At this time, when the first downlink HARQ process is used to receive the second MAC PDU, the operation state of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process can be changed to ensure that the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process corresponds to the transmission state of the current first downlink HARQ process, thereby avoiding the terminal from monitoring resources at unnecessary times, reducing the power consumption of the terminal, saving the battery power of the terminal, and extending the battery life of the terminal.

[0159] In one possible implementation, when the terminal receives the second MAC PDU on the PDSCH through SPS semi-persistent scheduling during the operation of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process, the operation state of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is changed.

[0160] When the terminal receives the second MAC PDU on the PDSCH through SPS semi-continuous scheduling, and the terminal is in the operation period of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process, in order to ensure that the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process corresponds to the transmission state of the current first downlink HARQ process, the operation state of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is changed.

[0161] In a possible implementation, when the second MAC PDU is received in the PDSCH using the first downlink HARQ process, the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is stopped.

[0162] When the terminal uses the first downlink HARQ process and receives the second MAC PDU in the PDSCH through SPS semi-persistent scheduling, the network side device will not send indication signaling to the terminal through PDCCH for a period of time after sending the second MAC PDU to PDSCH. Therefore, the terminal can first stop the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process to avoid unnecessary power consumption.

[0163] In a possible implementation, at the first time symbol after the first downlink HARQ process completes transmission of feedback for receiving the second MAC PDU, the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is started.

[0164] When the terminal uses the first downlink HARQ process to complete the reception of the second MAC PDU through SPS semi-persistent scheduling, the first downlink HARQ process is used to perform feedback transmission for the received second MAC PDU, so as to notify the network side device that the transmission of the second MAC PDU is completed. When the first downlink HARQ process completes the first time symbol after the feedback transmission for receiving the second MAC PDU, it indicates that the transmission operation of the second MAC PDU has been completed. At this time, the DRX-HARQ-RTT-TimerDL corresponding to the stopped first downlink HARQ process can be restarted, so that the terminal controls the PDCCH monitoring corresponding to the first downlink HARQ process according to the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process.

[0165] Figure 11 FIG. 1 shows a flow chart of a method for changing a timer state according to an embodiment of the present application. Figure 11As shown, it shows that in SPS semi-persistent scheduling, the terminal 1101 uses the first downlink HARQ process to receive the second MAC PDU sent by the network side device 1102 on the PDSCH. In this process, the terminal 1101 receives the second MAC PDU sent by the network side device 1102 at the specified time configured by the SPS semi-persistent scheduling. When the terminal 1101 starts to receive the second MAC PDU sent by the network side device 1102, and the first RetransmissionTimerDL is operating normally, the terminal can stop the first RetransmissionTimerDL at this time, and after using the first downlink HARQ process to receive the second MAC PDU, it can transmit HARQ feedback information to the network side device for receiving the second MAC PDU, and when the first time symbol after the HARQ feedback process is sent using the first downlink HARQ process, start the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process; when the terminal 1101 starts to receive the second MAC PDU sent by the network side device 1102, and the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is operating normally, the terminal can stop the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process, and after using the first downlink HARQ process to receive the second MAC The PDU transmits HARQ feedback information to the network side device, and when the first time symbol after the first downlink HARQ process is used to send the HARQ feedback process, the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is started.

[0166] In one possible implementation, during the operation of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process, when the terminal receives a PDCCH indicating to use the first downlink HARQ process to receive the second MAC PDU, the operation status of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is changed.

[0167] At this time, the first downlink HARQ process satisfies the second condition when, during the operation of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process, the terminal receives a PDCCH indicating that the first downlink HARQ process is used to receive the second MAC PDU. At this time, when the terminal uses the first downlink HARQ process and receives the second MAC PDU according to the instruction of the PDCCH, the operation state of the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process can be changed to ensure that the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process corresponds to the transmission state of the current first downlink HARQ process, and avoid using the first downlink HARQ process to monitor resources at unnecessary times, thereby reducing the power consumption of the terminal, saving the battery power of the terminal, and extending the battery life of the terminal.

[0168] In a possible implementation manner, when the terminal receives the PDCCH, the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is stopped.

[0169] When the terminal receives the PDCCH and the PDCCH indicates to use the first downlink HARQ process to transmit the first MAC PDU, the terminal can use the first downlink HARQ process to perform the operation of receiving the second MAC PDU according to the instruction of the PDCCH, that is, when the terminal receives the PDCCH, the terminal uses the first downlink HARQ process to start performing the operation of receiving the second MAC PDU. At this time, if the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is operating normally, the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process can be stopped when the terminal receives the PDCCH, so as to avoid the situation where the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process times out and causes the terminal to monitor resources at unnecessary times.

[0170] In a possible implementation, at the first time symbol after the first downlink HARQ process completes transmission of feedback for receiving the second MAC PDU, the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is started.

[0171] When the terminal uses the first downlink HARQ process to complete the reception of the second MAC PDU according to the instruction of the PDCCH, the terminal uses the first downlink HARQ process to transmit feedback for the received second MAC PDU, so as to notify the network-side device that the transmission of the second MAC PDU is completed. When the first time symbol after the feedback transmission for receiving the second MAC PDU is completed using the first downlink HARQ process, it indicates that the transmission operation of the second MAC PDU has been completed. At this time, the DRX-HARQ-RTT-TimerDL corresponding to the stopped first downlink HARQ process can be restarted, so that the terminal can monitor the PDCCH according to the DRX-HARQ-RTT-TimerDL instruction corresponding to the first downlink HARQ process.

[0172] In a possible implementation, when the terminal receives the PDCCH indicating to use the first downlink HARQ process to receive the second MAC PDU, the terminal stops the first RetransmissionTimerDL corresponding to the first downlink HARQ process.

[0173] Figure 12 FIG. 1 shows a flow chart of a method for changing a timer state according to an embodiment of the present application. Figure 12As shown, it shows that the terminal 1201 receives the second indication information in the PDCCH for indicating that the first downlink HARQ process receives the second MAC PDU sent by the network side device 1202. When the terminal 1201 receives the PDCCH, it can receive the second MAC PDU sent by the network side device 1202 according to the indication of the PDCCH. In this process, when the terminal 1201 receives the PDCCH and the first RetransmissionTimerDL is operating normally, the terminal can stop the first RetransmissionTimerDL at this time. After the terminal uses the first downlink HARQ process to receive the second MAC PDU, it can transmit HARQ feedback information to the network side device for receiving the second MAC PDU. When the terminal uses the first downlink HARQ process to send the first time symbol after the HARQ feedback process is sent, the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is started; when the terminal 1201 receives the PDCCH and the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is operating normally, the terminal can stop the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process. After the terminal uses the first downlink HARQ process to receive the second MAC PDU, it can The PDU transmits HARQ feedback information to the network side device. When the terminal uses the first downlink HARQ process to send the first time symbol after the HARQ feedback process is completed, the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is started.

[0174] Figure 13 This is a flowchart of a timer state changing method involved in an embodiment of the present application. Figure 13 FIG. 2 shows a state change of a DRX timer by the terminal when the terminal receives a PDCCH and performs data reception according to the PDCCH.

[0175] At time t1, when the terminal receives PDCCH and the drx-RetransmissionTimerUL corresponding to the first downlink HARQ process is in the started state, the terminal turns off the drx-RetransmissionTimerUL timer corresponding to the first downlink HARQ process; when the terminal receives PDCCH and the drx-HARQ-RTT-TimerUL corresponding to the first downlink HARQ process is in the started state, the terminal turns off the drx-HARQ-RTT-TimerUL corresponding to the first downlink HARQ process.

[0176] At time t2, when the terminal receives the PDCCH, it receives data sent by the network side device on the PDSCH indicated by the PDCCH.

[0177] At time t3, after the terminal uses the first downlink HARQ process to receive the second MAC PDU, the terminal can use the first downlink HARQ process to perform a feedback operation for receiving the second MAC PDU, and in the first time symbol after the feedback operation is completed, the terminal starts the drx-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process.

[0178] To sum up, in the scheme shown in the embodiment of the present application, when the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process of the terminal is running and the transmission process of the terminal meets the first condition, the network side device may not send PDCCH to the terminal within a period of time when the uplink transmission occurs. The terminal does not need to monitor the PDCCH at this time. Therefore, the terminal can change the running status of the DRX-HARQ-RTT-TimerUL corresponding to the first uplink HARQ process, such as by stopping or restarting to reasonably extend the next timeout time of RTT, thereby reducing unnecessary monitoring of the terminal due to DRX-HARQ-RTT-Timer timeout, reducing the power consumption of the terminal, and saving the power of the terminal.

[0179] The communication protocols involved in this application are also exemplified as follows:

[0180] 1> if a MAC PDU is transmitted in a configured uplink grant and LBTfailure indication is not received from lower layers:

[0181] > stop the drx-HARQ-RTT-TimerUL for the corresponding HARQ process at the first transmission (within a bundle) of the corresponding PUSCHtransmission

[0182] > start the drx-HARQ-RTT-TimerUL for the corresponding HARQ processin the first symbol after the end of the first transmission(within a bundle)of the corresponding PUSCH transmission;

[0183] > stop the drx-RetransmissionTimerUL for the corresponding HARQprocess at the first transmission(within a bundle)of the corresponding PUSCHtransmission.

[0184] 2> if a MAC PDU is transmitted in a configured uplink grant and LBTfailure indication is not received from lower layers:

[0185] > start or restart the drx-HARQ-RTT-TimerUL for the correspondingHARQ process in the first symbol after the end of the first transmission(within a bundle)of the corresponding PUSCH transmission;

[0186] > stop the drx-RetransmissionTimerUL for the corresponding HARQprocess at the first transmission (within a bundle)of the corresponding PUSCHtransmission.

[0187] > if the PDCCH indicates a UL transmission:

[0188] > stop the drx-HARQ-RTT-TimerUL for the corresponding HARQ process.

[0189] > start the drx-HARQ-RTT-TimerUL for the corresponding HARQ processin the first symbol after the end of the first transmission (within a bundle) of the corresponding PUSCH transmission;

[0190] > stop the drx-RetransmissionTimerUL for the corresponding HARQprocess.

[0191] That is, the method for changing the timer state corresponding to the uplink HARQ process may further include the following steps:

[0192] 1. The UE receives the DRX configuration from the network RRC.

[0193] 2. If the UE transmits a MAC PDU on the CG and does not receive an LBT failure indication from the physical layer, the UE's behavior includes at least one of the following:

[0194] Stop the drx-HARQ-RTT-TimerUL corresponding to the HARQ process when performing the first transmission of the PUSCH transmission (within a bundle);

[0195] Start the drx-HARQ-RTT-TimerUL corresponding to the HARQ process at the first (time) symbol after the first transmission (within a bundle) of the PUSCH transmission;

[0196] When performing the first transmission of the PUSCH (within a bundle), the RetransmissionTimerUL corresponding to the HARQ process is stopped.

[0197] Alternatively, the UE's behavior at this time includes at least one of the following:

[0198] Start or restart the drx-HARQ-RTT-TimerUL corresponding to the HARQ process at the first (time) symbol after the first transmission (within a bundle) of the PUSCH transmission is completed;

[0199] When performing the first transmission of the PUSCH (within a bundle), the RetransmissionTimerUL corresponding to the HARQ process is stopped.

[0200] 3. If the UE receives a PDCCH indicating uplink transmission, the UE's behavior is:

[0201] Stop the drx-HARQ-RTT-TimerUL corresponding to the HARQ process;

[0202] Start the drx-HARQ-RTT-TimerUL corresponding to the HARQ process at the first (time symbol) after the first transmission (within a bundle) of the PUSCH transmission is completed;

[0203] Stop the RetransmissionTimerUL corresponding to the HARQ process.

[0204] That is, the above solution states that after receiving the PDCCH indicating uplink scheduling, the UE stops the drx-HARQ-RTT-TimerUL corresponding to the uplink HARQ process. Alternatively, when the UE uses CG to transmit a MAC PDU, it stops the drx-HARQ-RTT-TimerUL corresponding to the HARQ process when performing the first transmission of the PUSCH transmission (within a bundle), or starts or restarts the drx-HARQ-RTT-TimerUL corresponding to the HARQ process in the first (time) symbol after completing the first transmission of the PUSCH transmission (within a bundle).

[0205] The communication protocols involved in this application are also exemplified as follows:

[0206] 1> if a MAC PDU is received in a configured downlink assignment:

[0207] > stop the drx-HARQ-RTT-TimerDL for the corresponding HARQ process.2>start the drx-HARQ-RTT-TimerDL for the corresponding HARQ process in the first symbol after the end of the corresponding transmission carrying the DLHARQ feedback;

[0208] > stop the drx-RetransmissionTimerDL for the corresponding HARQprocess.

[0209] 2> if the PDCCH indicates a DL transmission:

[0210] > stop the drx-HARQ-RTT-TimerDL for the corresponding HARQ process.

[0211] > start the drx-HARQ-RTT-TimerDL for the corresponding HARQ processin the first symbol after the end of the corresponding transmission carryingthe DL HARQ feedback;

[0212] NOTE 3:When HARQ feedback is postponed by PDSCH-to-HARQ_feedbacktiming indicating a non-numerical k1value,as specified in TS 38.213[6],thecorresponding transmission opportunity to send the DL HARQ feedback isindicated in a later PDCCH requesting the HARQ-ACK feedback.

[0213] > stop the drx-RetransmissionTimerDL for the corresponding HARQprocess.

[0214] > if the PDSCH-to-HARQ_feedback timing indicate a non-numericalk1value as specified in TS 38.213[6]:

[0215] > start the drx-RetransmissionTimerDL in the first symbol after the PDSCH transmission for the corresponding HARQ process.

[0216] That is, the method for changing the timer state corresponding to downlink HARQ may further include the following steps:

[0217] 1. The UE receives the DRX configuration from the network RRC.

[0218] 2. If the UE receives a MAC PDU on the SPS, the UE's behavior is:

[0219] Stop the drx-HARQ-RTT-TimerDL corresponding to the HARQ process;

[0220] Start the drx-HARQ-RTT-TimerDL corresponding to the HARQ process at the first (time) symbol after the HARQ feedback transmission for the downlink transmission is completed;

[0221] Stop the RetransmissionTimerDL corresponding to the HARQ process;

[0222] 3. If the UE receives a PDCCH indicating uplink transmission, the UE's behavior is:

[0223] Stop the drx-HARQ-RTT-TimerDL corresponding to the HARQ process;

[0224] Start the drx-HARQ-RTT-TimerDL corresponding to the HARQ process at the first (time) symbol after the HARQ feedback transmission for the downlink transmission is completed;

[0225] Stop the RetransmissionTimerDL corresponding to the HARQ process.

[0226] 4. When HARQ feedback is delayed according to the PDSCH-to-HARQ feedback time indication, which indicates a non-numeric k1 value, as specified in TS 38.213, the corresponding transmission opportunity for sending DL HARQ feedback is indicated in the PDCCH that requests HARQ-ack feedback later;

[0227] Stop the RetransmissionTimerDL corresponding to the HARQ process;

[0228] When the PDSCH-to-HARQ feedback time is as specified in TS 38.213, a non-numeric k1 value is indicated;

[0229] The drx-RetransmissionTimerDL is started in the first symbol after the PDSCH transmission of the corresponding HARQ process.

[0230] That is, the above solution records that after the UE receives the PDCCH scheduled under the instruction, it stops the drx-HARQ-RTT-TimerDL corresponding to the downlink HARQ process, or after the UE receives the MAC PDU on the SPS, it stops the drx-HARQ-RTT-TimerDL corresponding to the downlink HARQ process.
