Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method, apparatus, terminal and network device for controlling a discontinuous reception timer. Background Technology

[0002] Currently, for special HARQ feedback types (i.e., feedback types triggered by DCI scheduling), such as when the base station instructs the terminal to provide feedback on all carriers and all HARQ processes at once, if the terminal has already started a DRX downlink retransmission timer for a HARQ process, it must stop that downlink retransmission timer. In this case, the terminal cannot receive retransmission scheduling from the base station. However, special HARQ feedback targets multiple processes, especially Type-3 HARQ-ACK codebook, which targets all HARQ processes. This means that for all involved HARQ processes, any DRX downlink retransmission timers that may have already started must be stopped, which is clearly detrimental to the base station's timely retransmission scheduling. Similarly, if some processes have already started DRX downlink RTT timers and will soon start corresponding DRX downlink retransmission timers, the start of a new RTT timer will interrupt this process (e.g., ...). Figure 1 As shown in the figure, this causes a delay in the time when the base station can be scheduled. Figure 1 In this context, PDCCH represents the Physical Downlink Control Channel, and TB represents the Transport Block.

[0003] As shown above, existing technologies for special HARQ feedback types have drawbacks, such as the inability to perform retransmission scheduling in a timely manner. Summary of the Invention

If the T timer times out and downlink data is not received correctly, the second DRX retransmission timer is started; or the first DRX downlink retransmission timer is maintained or restarted. This enables the terminal to simultaneously send HARQ feedback from multiple HARQ processes according to network device instructions, or to retransmit HARQ feedback according to network device instructions, avoiding the DRX downlink retransmission timer being stopped or delayed. For HARQ processes that have already started the DRX downlink RTT timer or DRX downlink retransmission timer, retransmission scheduling can be obtained as early as possible, ensuring timely retransmission scheduling. This effectively solves the problem in existing technologies where retransmission scheduling cannot be performed in a timely manner due to non-continuous reception timer control schemes for special HARQ feedback types.

All of these systems include terminal equipment and network equipment. The systems may also include a core network component, such as Evolved Packet System (EPS) and 5G system (5GS).

[0167] Figure 2 This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes terminal devices and network devices. The terminal device may be simply referred to as a terminal, and is not limited thereto.

[0168] The terminal devices involved in the embodiments of this application can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but is not limited to these terms in the embodiments of this application.

[0169] The network device involved in this application embodiment can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, a base station may also be called an access point, or a device in an access network that communicates with a wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network.

In some network structures, the network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may be geographically separated.

[0170] Network devices and terminal devices can each use one or more antennas for multiple-input multiple-output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multiple-user MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, and can also be diversity transmission, precoding transmission, or beamforming transmission, etc.

[0171] The following section will first introduce the content related to the solutions provided in the embodiments of this application.

[0172] DRX refers to the discontinuous reception mechanism of connected terminals. This method allows the terminal to periodically enter a sleep state at certain times, not listening to PDCCH (Physical downlink control channel) subframes, and wake up from the sleep state when listening is needed, thus saving power. The DRX mechanism (DRX period) in connected mode is as follows: Figure 3 As shown: The "On Duration" period is the time during which the UE listens to downlink PDCCH subframes at the beginning of the DRX cycle. During this time, the UE is in a wake-up state. The "Opportunity for DRX" period, if no other timer is started, is the DRX sleep time, that is, the time during which the UE enters sleep mode and does not monitor PDCCH subframes in order to save power.

[0173] In addition, DRX operations mainly involve: drx-onDurationTimer (DRX duration timer), drx-InactivityTimer (DRX inactivity timer), drx-RetransmissionTimerDL (DRX downlink retransmission timer), drx-RetransmissionTimerUL (DRX uplink retransmission timer), drx-HARQ-RTT-TimerDL (DRX downlink RTT (Round-Trip Time) timer), and drx-HARQ-RTT-TimerUL (per UL). HARQprocess (DRX uplink RTT timer); during the operation of drx-onDurationTimer, drx-InactivityTimer (DRX activation timer), drx-RetransmissionTimerDL (DRX downlink retransmission timer), and drx-RetransmissionTimerUL (DRX uplink retransmission timer), the terminal is in the DRX active state and needs to listen to the base station's PDCCH scheduling. During the operation of drx-HARQ-RTT-TimerDL and drx-HARQ-RTT-TimerUL, the terminal is in the DRX inactive state and does not need to listen to the base station's PDCCH scheduling.

[0174] The main components of this solution are drx-HARQ-RTT-TimerDL and drx-RetransmissionTimerDL, both of which run for each HARQ process. Specifically, the operation is as follows: when the terminal receives downlink data from the base station and sends HARQ feedback, drx-HARQ-RTT-TimerDL is started. When drx-HARQ-RTT-TimerDL starts, drx-RetransmissionTimerDL for the corresponding HARQ process stops. If drx-HARQ-RTT-TimerDL times out and the terminal has not correctly received downlink transmission from that HARQ process, drx-RetransmissionTimerDL is started. This ensures that both the base station and the terminal have the same understanding of when the terminal is in a DRX active or inactive state, and the base station can schedule the terminal during the operation of drx-RetransmissionTimerDL.

[0175] In addition, 5G introduces new HARQ feedback types, including:

[0176] (1) The DCI (Downlink control information) carried by the PDCCH instructs the terminal to send feedback of all carriers and all HARQ processes at once, which is called the Type-3 HARQ-ACK codebook;

[0177] (2) An enhanced Type-3 HARQ-ACK codebook can be configured via the network, with the base station using DCI to instruct the terminal to send HARQ feedback only for a portion of the carriers and / or a portion of the HARQ process;

[0178] (3) The base station uses DCI to instruct the terminal to retransmit the previous HARQ feedback codebook.

[0179] Therefore, it is necessary to solve the problem of how to control the DRX timer (including the DRX downlink RTT timer and the DRX downlink retransmission timer) after the terminal sends a special state HARQ (Hybrid automatic repeat request) feedback during DRX (Discontinuous Reception) operation, so as to achieve a consistent understanding of the DRX state between the base station and the terminal, and enable the base station to schedule data retransmission in a timely manner.

[0180] Based on the above, embodiments of this application provide a discontinuous reception timer control method, apparatus, terminal, and network device to solve the problem in the prior art where retransmission scheduling cannot be performed in a timely manner for special HARQ feedback types. The method, apparatus, terminal, and network device are based on the same application concept. Since the principles underlying the problem-solving of the method, apparatus, terminal, and network device are similar, their implementations can be referred to interchangeably, and repeated details will not be elaborated further.

[0181] The discontinuous reception timer control method provided in this application embodiment is applied to a terminal, such as... Figure 4 As shown, it includes:

[0182] Step 41: After executing the first Hybrid Automatic Repeat Request (HARQ) feedback, perform a first control operation on at least one discontinuous reception DRX downlink retransmission timer corresponding to a first HARQ process; wherein, the first HARQ feedback is a HARQ feedback triggered by downlink control information (DCI) scheduling; the first HARQ process refers to: the HARQ process corresponding to the first HARQ feedback that has started the first DRX downlink round-trip timeout (RTT) timer or the first DRX downlink retransmission timer before executing the first HARQ feedback; the first control operation includes at least one of the following: starting a second DRX retransmission timer when the first DRX downlink RTT timer times out and downlink data is not received correctly; or maintaining or restarting the first DRX downlink retransmission timer.

[0183] "Correct reception" can mean that the terminal can correctly decode the downlink data transmitted in the process, but it is not limited to this.

[0184] The discontinuous reception timer control method provided in this application embodiment performs a first control operation on at least one discontinuous reception DRX downlink retransmission timer corresponding to a first HARQ process after executing a first Hybrid Automatic Repeat Request (HARQ) feedback. The first HARQ feedback is a HARQ feedback triggered by downlink control information (DCI) scheduling. The first HARQ process refers to a HARQ process corresponding to the first HARQ feedback that has already started a first DRX downlink round-trip timeout (RTT) timer or a first DRX downlink retransmission timer before executing the first HARQ feedback. The first control operation includes at least one of the following: [The text abruptly ends here, likely due to an incomplete sentence or a missing section.] If the TT timer times out and downlink data is not received correctly, the second DRX retransmission timer is started; or the first DRX downlink retransmission timer is maintained or restarted. This enables the terminal to simultaneously send HARQ feedback from multiple HARQ processes according to network device instructions, or to retransmit HARQ feedback according to network device instructions, avoiding the DRX downlink retransmission timer being stopped or delayed. For HARQ processes that have already started the DRX downlink RTT timer or DRX downlink retransmission timer, retransmission scheduling can be obtained as early as possible, ensuring timely retransmission scheduling. This effectively solves the problem in existing technologies where retransmission scheduling cannot be performed in a timely manner due to non-continuous reception timer control schemes for special HARQ feedback types.

[0185] The HARQ feedback triggered by the DCI scheduling includes at least one of the following: HARQ feedback of all current carriers and all HARQ processes fed back by the terminal at one time (specifically corresponding to the DCI instructing the feedback of Type-3 HARQ-ACK code on the PUCCH); or HARQ feedback of some carriers and / or some HARQ processes fed back by the terminal at one time (specifically corresponding to the DCI instructing the feedback of enhanced Type-3 HARQ-ACK code on the PUCCH); or the HARQ feedback of the previous retransmission by the terminal.

[0186] In this embodiment of the application, the step of starting the second DRX retransmission timer when the first DRX downlink RTT timer times out and downlink data is not received correctly includes: if the first DRX downlink RTT timer has already been started before the execution of the first HARQ feedback, continuing to run the first DRX downlink RTT timer without starting other DRX downlink RTT timers; starting the second DRX retransmission timer when the first DRX downlink RTT timer times out and downlink data is not received correctly; or, if the first DRX downlink RTT timer has already been started before the execution of the first HARQ feedback, continuing to run the first DRX downlink RTT timer and starting the second DRX downlink RTT timer; starting the second DRX retransmission timer when the first DRX downlink RTT timer times out and downlink data is not received correctly, and restarting the second DRX retransmission timer when the second DRX downlink RTT timer times out.

[0187] "Continue running" can also be understood as "continue maintenance," and is not limited here. "Do not start other DRX downlink RTT timers" can mean not starting any DRX downlink RTT timers for the first HARQ process other than the first DRX downlink RTT timer; it can also include not restarting the first DRX downlink RTT timer; "Do not start other DRX downlink RTT timers" can also be understood as: not starting the DRX downlink RTT timer corresponding to the first HARQ feedback, and is not limited here.

[0188] The step of maintaining or restarting the first DRX downlink retransmission timer includes: if the first DRX downlink retransmission timer has already been started before the execution of the first HARQ feedback, continuing to run the first DRX downlink retransmission timer without starting the DRX downlink RTT timer corresponding to the first HARQ process; or, if the first DRX downlink retransmission timer has already been started before the execution of the first HARQ feedback, continuing to run the first DRX downlink retransmission timer and starting the third DRX downlink RTT timer; if the first DRX downlink retransmission timer times out and the downlink data packet is not received correctly, extending the duration of the DRX downlink retransmission timer; or, if the first DRX downlink retransmission timer has already been started before the execution of the first HARQ feedback and the downlink data packet is not received correctly, restarting the first DRX downlink retransmission timer.

[0189] In this embodiment of the application, extending the duration of the DRX downlink retransmission timer includes any one of the following: (1) starting the third DRX downlink retransmission timer when the third DRX downlink RTT timer times out; (2) setting the terminal to an active state during the time period between the first DRX downlink retransmission timer and the third DRX downlink retransmission timer, and starting the third DRX downlink retransmission timer when the third DRX downlink RTT timer times out; (3) extending the length of the first DRX downlink retransmission timer to the start time of the third DRX downlink retransmission timer; and starting the third DRX downlink retransmission timer when the third DRX downlink RTT timer times out; (4) extending the length of the first DRX downlink retransmission timer to a first length; the first length is equal to the sum of the first DRX downlink retransmission timer, the third DRX downlink retransmission timer, and the time interval, wherein the time interval is the time interval between the first DRX downlink retransmission timer and the third DRX downlink retransmission timer.

[0190] In this embodiment, the first DRX downlink retransmission timer times out first, and the third DRX downlink RTT Timer (timer) that is started times out later, with a time gap in between. The third DRX downlink RTT Timer that is started is used to start the third DRX downlink retransmission timer.

[0191] Furthermore, during the operation of the first DRX downlink retransmission timer and / or the third DRX downlink retransmission timer, the terminal enters an active state and listens to the Physical Downlink Control Channel (PDCCH) scheduling.

[0192] This application also provides a method for controlling a discontinuous reception timer, applicable to network devices, such as... Figure 5 As shown, it includes:

[0193] Step 51: After receiving the first Hybrid Automatic Repeat Request (HARQ) feedback, perform a first control operation on at least one discontinuous reception DRX downlink retransmission timer corresponding to a first HARQ process; wherein, the first HARQ feedback is a HARQ feedback triggered by downlink control information (DCI) scheduling; the first HARQ process refers to: the HARQ process corresponding to the first HARQ feedback that has started a first DRX downlink round-trip timeout (RTT) timer or a first DRX downlink retransmission timer before receiving the first HARQ feedback; the first control operation includes at least one of the following: starting a second DRX retransmission timer when the first DRX downlink RTT timer expires and the first HARQ feedback includes a first acknowledgment feedback; the first acknowledgment feedback is a HARQ negative acknowledgment feedback for the first HARQ process; or maintaining or restarting the first DRX downlink retransmission timer.

[0194] The phrase "receive the first Hybrid Automatic Repeat Request (HARQ) feedback" can specifically mean: receiving the first Hybrid Automatic Repeat Request (HARQ) feedback sent by the terminal; the phrase "the first HARQ feedback includes the first acknowledgment feedback" corresponds to "not received correctly" on the terminal side. "Received correctly" can mean that the terminal can correctly decode the downlink data transmitted in the process, but is not limited to this.

[0195] The discontinuous reception timer control method provided in this application performs a first control operation on at least one discontinuous reception DRX downlink retransmission timer corresponding to a first HARQ process after receiving a first Hybrid Automatic Repeat Request (HARQ) feedback. The first HARQ feedback is a HARQ feedback triggered by downlink control information (DCI) scheduling. The first HARQ process refers to a HARQ process corresponding to the first HARQ feedback that has already started a first DRX downlink round-trip timeout (RTT) timer or a first DRX downlink retransmission timer before receiving the first HARQ feedback. The first control operation includes at least one of the following: if the first DRX downlink RTT timer times out and the first HARQ feedback includes a first acknowledgment feedback, initiating a second DRX retransmission timer. The system transmits a timer; the first response feedback is a HARQ negative response feedback for the first HARQ process; or maintains or restarts the first DRX downlink retransmission timer; it can support the terminal to simultaneously send HARQ feedback for multiple HARQ processes according to the network device's instruction, or to retransmit HARQ feedback according to the network device's instruction, avoiding the DRX downlink retransmission timer being stopped or delayed. For HARQ processes that have already started the DRX downlink RTT timer or DRX downlink retransmission timer, it can obtain retransmission scheduling as early as possible, achieving consistent understanding of the DRX status between the network device and the terminal, and ensuring timely retransmission scheduling (i.e., the network device can schedule data retransmission in a timely manner); it effectively solves the problem in the prior art where the non-continuous reception timer control scheme for special HARQ feedback types causes the retransmission scheduling to fail to be performed in a timely manner.

[0196] The HARQ feedback triggered by the DCI scheduling includes at least one of the following: HARQ feedback of all current carriers and all HARQ processes fed back by the terminal at one time (specifically corresponding to the DCI instruction to feed back Type-3 HARQ-ACK code on PUCCH); or HARQ feedback of some carriers and / or some HARQ processes fed back by the terminal at one time (specifically corresponding to the DCI instruction to feed back Enhanced Type-3 HARQ-ACK code on PUCCH); or HARQ feedback of the previous retransmission by the terminal.

[0197] In this embodiment of the application, starting the second DRX retransmission timer when the first DRX downlink RTT timer times out and the first HARQ feedback includes the first acknowledgment feedback includes: if the first DRX downlink RTT timer has already been started before receiving the first HARQ feedback, continuing to run the first DRX downlink RTT timer without starting other DRX downlink RTT timers; starting the second DRX retransmission timer when the first DRX downlink RTT timer times out and the first HARQ feedback includes the first acknowledgment feedback; or, if the first DRX downlink RTT timer has already been started before receiving the first HARQ feedback, continuing to run the first DRX downlink RTT timer and starting the second DRX downlink RTT timer; starting the second DRX retransmission timer when the first DRX downlink RTT timer times out and the first HARQ feedback includes the first acknowledgment feedback, and restarting the second DRX retransmission timer when the second DRX downlink RTT timer times out.

[0198] "Continue running" can also be understood as "continue maintenance," and is not limited here. "Do not start other DRX downlink RTT timers" can mean not starting any DRX downlink RTT timers for the first HARQ process other than the first DRX downlink RTT timer; it can also include not restarting the first DRX downlink RTT timer; "Do not start other DRX downlink RTT timers" can also be understood as: not starting the DRX downlink RTT timer corresponding to the first HARQ feedback, and is not limited here.

[0199] The step of maintaining or restarting the first DRX downlink retransmission timer includes: if the first DRX downlink retransmission timer has already been started before receiving the first HARQ feedback, continuing to run the first DRX downlink retransmission timer without starting the DRX downlink RTT timer corresponding to the first HARQ process; or, if the first DRX downlink retransmission timer has already been started before receiving the first HARQ feedback, continuing to run the first DRX downlink retransmission timer and starting the third DRX downlink RTT timer; if the first DRX downlink retransmission timer times out and the first HARQ feedback includes the first acknowledgment feedback, extending the duration of the DRX downlink retransmission timer; or, if the first DRX downlink retransmission timer has already been started before receiving the first HARQ feedback and the first HARQ feedback includes the first acknowledgment feedback, restarting the first DRX downlink retransmission timer.

[0200] In this embodiment of the application, extending the duration of the DRX downlink retransmission timer includes any one of the following: (1) starting the third DRX downlink retransmission timer when the third DRX downlink RTT timer times out; (2) determining that the terminal is set to an active state during the time period between the first DRX downlink retransmission timer and the third DRX downlink retransmission timer, and starting the third DRX downlink retransmission timer when the third DRX downlink RTT timer times out; (3) extending the length of the first DRX downlink retransmission timer to the start time of the third DRX downlink retransmission timer; and starting the third DRX downlink retransmission timer when the third DRX downlink RTT timer times out; (4) extending the length of the first DRX downlink retransmission timer to a first length; the first length is equal to the sum of the first DRX downlink retransmission timer, the third DRX downlink retransmission timer, and the time interval, wherein the time interval is the time interval between the first DRX downlink retransmission timer and the third DRX downlink retransmission timer.

[0201] The term "terminal" in option (2) above can specifically refer to the terminal that sends the first HARQ feedback, but is not limited here.

[0202] In this embodiment, the first DRX downlink retransmission timer times out first, and the third DRX downlink RTT Timer (timer) that is started times out later, with a time gap in between. The third DRX downlink RTT Timer that is started is used to start the third DRX downlink retransmission timer.

[0203] Furthermore, during the operation of the first DRX downlink retransmission timer and / or the third DRX downlink retransmission timer, the terminal enters an active state, and the network device is able to send a Physical Downlink Control Channel (PDCCH) scheduling instruction (i.e., a scheduling command) to the terminal.

[0204] The following is an example illustrating the discontinuous reception timer control method provided in the embodiments of this application, with a base station as an example of a network device.

[0205] To address the aforementioned technical problems, this application provides a discontinuous reception timer control method, which mainly involves: after the terminal sends a special type of HARQ feedback (corresponding to the first HARQ feedback mentioned above), performing special processing (corresponding to the first control operation mentioned above) on the DRX downlink retransmission timer (drx-RetransmissionTimerDL) in the HARQ process corresponding to the HARQ feedback (corresponding to the first HARQ process mentioned above), so that the terminal can listen to the base station PDCCH scheduling command in a timely manner (or as soon as possible) (i.e., so that the terminal can receive the PDCCH in a timely manner (or as soon as possible).

[0206] Specifically, this plan involves the following:

[0207] 1. Special types of HARQ feedback include at least one of the following HARQ feedbacks triggered by DCI scheduling:

[0208] (Type 1) The base station uses DCI to instruct the terminal to provide HARQ feedback for all current carriers and all HARQ processes at once;

[0209] (Type 2) The base station uses DCI to instruct the terminal to provide HARQ feedback for a specified carrier (corresponding to the above-mentioned partial carriers) and / or a specified HARQ process (corresponding to the above-mentioned partial HARQ process) in one go;

[0210] (Type 3) The base station uses DCI to instruct the terminal to retransmit the previous HARQ feedback.

[0211] 2. Special handling is required for the DRX downlink retransmission timer in the HARQ process corresponding to the HARQ feedback, including any of the following:

[0212] (1) If the DRX downlink RTT timer (RTT timer 1, corresponding to the first DRX downlink RTT timer mentioned above) has been started before the special type HARQ feedback:

[0213] 1) After the terminal sends this special type of HARQ feedback, it does not start the DRX downlink RTT timer (corresponding to not starting other DRX downlink RTT timers as mentioned above), and continues to maintain RTT timer 1. When RTT timer 1 times out and downlink data is not received correctly, it starts the DRX retransmission timer (corresponding to the second DRX retransmission timer mentioned above); or

[0214] 2) After the terminal sends this special type of HARQ feedback, it starts the DRX downlink RTT timer (RTT timer 2, corresponding to the second DRX downlink RTT timer mentioned above) and continues to maintain RTT timer 1. When RTT timer 1 times out and downlink data is not received correctly, the DRX retransmission timer (corresponding to the second DRX retransmission timer mentioned above) is started. When RTT timer 2 times out, the DRX retransmission timer (corresponding to the second DRX retransmission timer mentioned above) is restarted.

[0215] (2) If the DRX downlink retransmission timer (retransmission timer 1, corresponding to the first DRX downlink retransmission timer mentioned above) has been started before the special type HARQ feedback:

[0216] 1) After the terminal sends this special type of HARQ feedback, it does not start the DRX downlink RTT timer (corresponding to not starting the DRX downlink RTT timer corresponding to the first HARQ process mentioned above), and continues to run retransmission timer 1. During the operation of retransmission timer 1 (i.e., before timeout), the terminal enters the active state and listens for PDCCH scheduling; or

[0217] 2) After the terminal sends this special type of HARQ feedback, it starts the DRX downlink RTT timer (corresponding to the third DRX downlink RTT timer mentioned above), but does not stop retransmission timer 1 (corresponding to the continued operation of the first DRX downlink retransmission timer mentioned above); when the RTT timer expires (corresponding to the third DRX downlink RTT timer mentioned above), if the downlink data packet of the HARQ process is not received correctly, the DRX downlink retransmission timer (retransmission timer 2, corresponding to the third DRX downlink retransmission timer mentioned above) is started; corresponding to the above-mentioned start of the third DRX downlink retransmission timer when the third DRX downlink RTT timer expires. Optionally, the terminal is also set to an active state during the time period between the timeout of retransmission timer 1 and the start of retransmission timer 2 (corresponding to setting the terminal to an active state during the time period between the first DRX downlink retransmission timer and the third DRX downlink retransmission timer). Specifically, retransmission timer 1 can be extended to the start time of retransmission timer 2 (corresponding to extending the length of the first DRX downlink retransmission timer to the start time of the third DRX downlink retransmission timer), or the length of the DRX downlink retransmission timer can be extended by retransmission timer 1 + retransmission timer 2 + the time interval between retransmission timers 1 and 2 (corresponding to extending the length of the first DRX downlink retransmission timer to the first length). During the operation of retransmission timer 1 and retransmission timer 2, the terminal enters an active state and listens to PDCCH scheduling; or

[0218] 3) After the terminal sends this special type of HARQ feedback, if the downlink data packet of the HARQ process is not received correctly, the DRX downlink retransmission timer (corresponding to the first DRX downlink retransmission timer mentioned above) is restarted, that is, the DRX downlink retransmission timer starts running from the initial value.

[0219] This application takes into account that: the base station needs to maintain a timer, otherwise the base station will not know when the terminal is in the activation period, and therefore will not know when to send a scheduling command. Therefore, the base station can perform timer control operations similar to those of the terminal, which will not be elaborated here.

[0220] The following provides specific examples of the solutions provided in the embodiments of this application.

[0221] Example 1: Before the terminal sends a special type of HARQ feedback, the terminal starts the DRX downlink RTT timer (1) of HARQ process 1;

[0222] Terminal side:

[0223] Step 1: Receive downlink transmissions from HARQ process 1 and HARQ process 2. If HARQ process 1 has a defined HARQ feedback resource, send HARQ feedback for HARQ process 1 and start the DRX downlink RTT timer of HARQ process 1.

[0224] Step 2: Upon receiving the DCI (indicating the need to send a special type of HARQ feedback) carried by the base station via PDCCH, send the HARQ feedback, such as... Figure 6 As shown, the terminal provides feedback on HARQ feedback for HARQ process 1 and HARQ process 2. The terminal does not start the DRX downlink RTT timer of HARQ process 1 separately (corresponding to the above-mentioned continued running of the first DRX downlink RTT timer and no start of other DRX downlink RTT timers), but only starts the DRX downlink RTT timer of HARQ process 2.

[0225] Step 3: When the DRX downlink RTT timer of HARQ process 1 times out, the DRX retransmission timer is started; when the DRX downlink RTT timer of HARQ process 2 times out, the DRX retransmission timer is started. The terminal remains active during the execution of any DRX retransmission timer.

[0226] Base station side:

[0227] Step 1: Send downlink transmissions of HARQ process 1 and HARQ process 2. HARQ process 1 has a defined HARQ feedback resource. Receive HARQ feedback for HARQ process 1 and start the DRX downlink RTT timer of HARQ process 1.

[0228] Step 2: Send the DCI (indicating the sending of a special type of HARQ feedback) carried by the PDCCH, and receive the HARQ feedback, such as... Figure 6 As shown, the terminal feedback for HARQ feedback of HARQ process 1 and HARQ process 2 does not start the DRX downlink RTT timer of HARQ process 1 separately (corresponding to the above-mentioned continued running of the first DRX downlink RTT timer and no start of other DRX downlink RTT timers), but only starts the DRX downlink RTT timer of HARQ process 2.

[0229] Step 3: When the DRX downlink RTT timer of HARQ process 1 times out, the DRX retransmission timer is started; when the DRX downlink RTT timer of HARQ process 2 times out, the DRX retransmission timer is started. During the execution of either DRX retransmission timer, the base station can send PDCCH to the terminal.

[0230] In this example diagram, the base station instructs the terminal to send HARQ feedback for multiple processes at once (i.e., the special types of HARQ feedback 1 and 2 mentioned above). The operation is the same for the base station instructing the terminal to send HARQ feedback retransmission (i.e., special type of HARQ feedback 3), and will not be described again here.

[0231] Example 2: Before the terminal sends a special type of HARQ feedback, the terminal starts the DRX downlink RTT timer (2) of HARQ process 1;

[0232] Terminal side:

[0233] Step 1: Receive downlink transmissions from HARQ process 1 and HARQ process 2. If HARQ process 1 has a defined HARQ feedback resource, send HARQ feedback for HARQ process 1 and start the DRX downlink RTT timer (RTT timer 1) of HARQ process 1.

[0234] Step 2: Upon receiving the DCI (indicating the need to send a special type of HARQ feedback) carried by the base station via PDCCH, send the HARQ feedback, such as... Figure 7 As shown, the terminal feedback is for HARQ process 1 and HARQ process 2. For HARQ process 1, an additional DRX downlink RTT timer (RTT timer 2) is started, and for HARQ process 2, a corresponding DRX downlink RTT timer is started.

[0235] Step 3: When RTT timer 1 of HARQ process 1 times out, the DRX retransmission timer is started. When RTT timer 2 times out, if the downlink transmission is still not successfully received, the DRX retransmission timer is restarted (i.e., the DRX retransmission timer started when RTT timer 1 times out is restarted). When the DRX downlink RTT timer of HARQ process 2 times out, a (corresponding) DRX retransmission timer is started. The terminal is active during the execution of any DRX retransmission timer. In this example, only one DRX retransmission timer is maintained for one HARQ process. See [link to example]. Figure 7 The first retransmission timer of HARQ process 1 stops when the second retransmission timer starts (i.e., the DRX retransmission timer is restarted).

[0236] Base station side:

[0237] Step 1: Send downlink transmissions of HARQ process 1 and HARQ process 2. If HARQ process 1 has a defined HARQ feedback resource, then receive HARQ feedback for HARQ process 1 and start the DRX downlink RTT timer (RTT timer 1) of HARQ process 1.

[0238] Step 2: Send the DCI (indicating the sending of a special type of HARQ feedback) carried by the PDCCH, and receive the HARQ feedback, such as... Figure 7 As shown, the terminal feedback is for HARQ process 1 and HARQ process 2. For HARQ process 1, an additional DRX downlink RTT timer (RTT timer 2) is started, and for HARQ process 2, a corresponding DRX downlink RTT timer is started.

[0239] Step 3: When RTT timer 1 of HARQ process 1 times out, the DRX retransmission timer is started. When RTT timer 2 times out, if downlink transmission is still not successfully received, the DRX retransmission timer is restarted (i.e., the DRX retransmission timer started when RTT timer 1 times out is restarted). When the DRX downlink RTT timer of HARQ process 2 times out, a (corresponding) DRX retransmission timer is started. During the operation of any DRX retransmission timer, the base station can send PDCCH to the terminal.

[0240] In this example diagram, the base station instructs the terminal to send HARQ feedback for multiple processes at once (i.e., the special types of HARQ feedback 1 and 2 mentioned above). The operation is the same for the base station instructing the terminal to send HARQ feedback retransmission (i.e., special type of HARQ feedback 3), and will not be described again here.

[0241] Example 3: Before the terminal sends a special type of HARQ feedback, the terminal starts the DRX downlink retransmission timer (1) of HARQ process 1;

[0242] Terminal side:

[0243] Step 1: Receive downlink transmissions from HARQ process 1 and HARQ process 2. If HARQ process 1 has a defined HARQ feedback resource, send HARQ feedback for HARQ process 1 and start the DRX downlink RTT timer of HARQ process 1. If the DRX downlink RTT timer expires and downlink data is not received correctly, start the DRX downlink retransmission timer of process 1.

[0244] Step 2: Upon receiving the DCI (indicating the need to send a special type of HARQ feedback) carried by the base station via PDCCH, send the HARQ feedback, such as... Figure 8 As shown, the terminal provides feedback on HARQ feedback for HARQ process 1 and HARQ process 2. The terminal does not start the DRX downlink RTT timer of HARQ process 1 (corresponding to not starting the DRX downlink RTT timer corresponding to the first HARQ process mentioned above), but only starts the DRX downlink RTT timer of HARQ process 2.

[0245] Step 3: Continue running the DRX retransmission timer for HARQ process 1; when the DRX downlink RTT timer for HARQ process 2 times out, start the DRX retransmission timer. During the execution of any DRX retransmission timer, the terminal is in an active state and can receive PDCCH commands from the base station.

[0246] Base station side:

[0247] Step 1: Send downlink transmissions of HARQ process 1 and HARQ process 2. HARQ process 1 has a defined HARQ feedback resource. Receive HARQ feedback for HARQ process 1. Start the DRX downlink RTT timer of HARQ process 1. When the DRX downlink RTT timer expires and downlink data is not received correctly, start the DRX downlink retransmission timer of process 1.

[0248] Step 2: Send the DCI (indicating the sending of a special type of HARQ feedback) carried by the PDCCH, and receive the HARQ feedback, such as... Figure 8 As shown, the terminal feedback for HARQ feedback of HARQ process 1 and HARQ process 2 does not start the DRX downlink RTT timer of HARQ process 1 (corresponding to not starting the DRX downlink RTT timer corresponding to the first HARQ process above), and only starts the DRX downlink RTT timer of HARQ process 2.

[0249] Step 3: Continue running the DRX retransmission timer for HARQ process 1; when the DRX downlink RTT timer for HARQ process 2 times out, start the DRX retransmission timer. During the execution of any DRX retransmission timer, the base station can send PDCCH scheduling commands to the terminal.

[0250] In this example diagram, the base station instructs the terminal to send HARQ feedback for multiple processes at once (i.e., the special types of HARQ feedback 1 and 2 mentioned above). The operation is the same for the base station instructing the terminal to send HARQ feedback retransmission (i.e., special type of HARQ feedback 3), and will not be described again here.

[0251] Example 4: Before the terminal sends a special type of HARQ feedback, the terminal starts the DRX downlink retransmission timer (2) of HARQ process 1;

[0252] Terminal side:

[0253] Step 1: Receive downlink transmissions from HARQ process 1 and HARQ process 2. If HARQ process 1 has a defined HARQ feedback resource, send HARQ feedback for HARQ process 1 and start the DRX downlink RTT timer of HARQ process 1. If the DRX downlink RTT timer expires and downlink data is not received correctly, start the DRX downlink retransmission timer (retransmission timer 1) of HARQ process 1.

[0254] Step 2: Upon receiving the DCI (indicating the need to send a special type of HARQ feedback) carried by the base station via PDCCH, send the HARQ feedback, such as... Figure 9 As shown, the terminal provides HARQ feedback for HARQ process 1 and HARQ process 2. The terminal starts the DRX downlink RTT timer for HARQ process 1 and the DRX downlink RTT timer for HARQ process 2.

[0255] Step 3: Continue running the DRX retransmission timer (retransmission timer 1) for HARQ process 1; when the DRX downlink RTT timer for HARQ process 1 times out, start the DRX retransmission timer (retransmission timer 2); when the DRX downlink RTT timer for HARQ process 2 times out, start (a corresponding) DRX retransmission timer. During the execution of any DRX retransmission timer, the terminal is active and can receive PDCCH commands from the base station. Optionally, the terminal can extend the DRX downlink retransmission timer for HARQ process 1 to: retransmission timer 1 + retransmission timer 2 + the time interval between retransmission timers 1 and 2, instead of specifying two retransmission timers for a single HARQ process.

[0256] Base station side:

[0257] Step 1: Send downlink transmissions of HARQ process 1 and HARQ process 2. HARQ process 1 has a defined HARQ feedback resource. Receive HARQ feedback for HARQ process 1. Start the DRX downlink RTT timer of HARQ process 1. When the DRX downlink RTT timer expires and downlink data is not received correctly, start the DRX downlink retransmission timer (retransmission timer 1) of process 1.

[0258] Step 2: Send the DCI (indicating the sending of a special type of HARQ feedback) carried by the PDCCH, and receive the HARQ feedback, such as... Figure 9 As shown, the terminal feedback is for HARQ feedback of HARQ process 1 and HARQ process 2, starts the DRX downlink RTT timer of HARQ process 1, and starts the DRX downlink RTT timer of HARQ process 2.

[0259] Step 3: Continue running the DRX retransmission timer (retransmission timer 1) for HARQ process 1; when the DRX downlink RTT timer for HARQ process 1 times out, start the DRX retransmission timer (retransmission timer 2); when the DRX downlink RTT timer for HARQ process 2 times out, start (a corresponding) DRX retransmission timer. During the execution of any DRX retransmission timer, the base station can send PDCCH scheduling commands to the terminal. Optionally, the DRX downlink retransmission timer for HARQ process 1 can be extended to: retransmission timer 1 + retransmission timer 2 + the length of the time interval between retransmission timers 1 and 2, instead of specifying two retransmission timers for a single HARQ process.

[0260] In this example diagram, the base station instructs the terminal to send HARQ feedback for multiple processes at once (i.e., the special types of HARQ feedback 1 and 2 mentioned above). The operation is the same for the base station instructing the terminal to send HARQ feedback retransmission (i.e., special type of HARQ feedback 3), and will not be described again here.

[0261] Example 5: Before the terminal sends a special type of HARQ feedback, the terminal starts the DRX downlink retransmission timer (3) of HARQ process 1;

[0262] Terminal side:

[0263] Step 1: Receive downlink transmissions from HARQ process 1 and HARQ process 2. If HARQ process 1 has a defined HARQ feedback resource, send HARQ feedback for HARQ process 1 and start the DRX downlink RTT timer of HARQ process 1. If the DRX downlink RTT timer expires and downlink data is not received correctly, start the DRX downlink retransmission timer of HARQ process 1.

[0264] Step 2: Upon receiving the DCI (indicating the need to send a special type of HARQ feedback) carried by the base station via PDCCH, send the HARQ feedback, such as... Figure 10 As shown ( Figure 10 In the diagram, 'a' represents the DRX downlink retransmission timer. The terminal provides HARQ feedback for HARQ process 1 and HARQ process 2. If the downlink data packet of HARQ process 1 is not received correctly, the terminal restarts the DRX downlink retransmission timer of HARQ process 1 and starts the DRX downlink RTT timer of HARQ process 2.

[0265] Step 3: Continue running the (restarted) HARQ process 1's DRX retransmission timer; if the HARQ process 2's DRX downlink RTT timer times out, start (a corresponding) DRX retransmission timer. During the execution of any DRX retransmission timer, the terminal is active and can receive PDCCH commands from the base station.

[0266] Base station side:

[0267] Step 1: Send downlink transmissions of HARQ process 1 and HARQ process 2. HARQ process 1 has a defined HARQ feedback resource. Receive HARQ feedback for HARQ process 1. Start the DRX downlink RTT timer of HARQ process 1. When the DRX downlink RTT timer expires and downlink data is not received correctly, start the DRX downlink retransmission timer of HARQ process 1.

[0268] Step 2: Send the DCI (indicating the sending of a special type of HARQ feedback) carried by the PDCCH, and receive the HARQ feedback, such as... Figure 10 As shown, the terminal provides feedback on HARQ feedback for HARQ process 1 and HARQ process 2. (If the downlink data packet of HARQ process 1 is not received correctly) the DRX downlink retransmission timer of HARQ process 1 is restarted and the DRX downlink RTT timer of HARQ process 2 is started.

[0269] Step 3: Continue running the (restarted) HARQ process 1's DRX retransmission timer; if the HARQ process 2's DRX downlink RTT timer times out, start (a corresponding) DRX retransmission timer. During the execution of any DRX retransmission timer, the base station can send PDCCH scheduling commands to the terminal.

[0270] In this example diagram, the base station instructs the terminal to send HARQ feedback for multiple processes at once (i.e., the special types of HARQ feedback 1 and 2 mentioned above). The operation is the same for the base station instructing the terminal to send HARQ feedback retransmission (i.e., special type of HARQ feedback 3), and will not be described again here.

[0271] It should be noted that similar content in the above examples can be referred to in turn, and will not be repeated here.

[0272] Therefore, this solution can obtain base station retransmission scheduling as early as possible for HARQ processes that have started DRX downlink RTT timers or DRX downlink retransmission timers when the terminal sends HARQ feedback of multiple HARQ processes simultaneously according to the base station's instructions, or when retransmitting HARQ feedback according to the base station's instructions.

[0273] This application also provides a terminal, such as... Figure 11 As shown, it includes a memory 111, a transceiver 112, and a processor 113:

[0274] Memory 111 is used to store computer programs; transceiver 112 is used to send and receive data under the control of processor 113; processor 113 is used to read the computer program in memory 111 and perform the following operations:

[0275] After executing the first Hybrid Automatic Repeat Request (HARQ) feedback, a first control operation is performed on at least one discontinuous reception DRX downlink repeat timer corresponding to the first HARQ process.

[0276] The first HARQ feedback is a HARQ feedback triggered by downlink control information (DCI) scheduling;

[0277] The first HARQ process refers to the HARQ process corresponding to the first HARQ feedback, in which the first DRX downlink round-trip timer or the first DRX downlink retransmission timer has been started before the first HARQ feedback is executed.

[0278] The first control operation includes at least one of the following:

[0279] If the first DRX downlink RTT timer times out and downlink data is not received correctly, the second DRX retransmission timer is started; or

[0280] Maintain or restart the first DRX downlink retransmission timer.

[0281] The terminal provided in this application embodiment performs a first control operation on at least one discontinuous reception DRX downlink retransmission timer corresponding to a first HARQ process after executing a first Hybrid Automatic Repeat Request (HARQ) feedback; wherein, the first HARQ feedback is a HARQ feedback triggered by downlink control information (DCI) scheduling; the first HARQ process refers to a HARQ process that has started a first DRX downlink round-trip timeout (RTT) timer or a first DRX downlink retransmission timer before executing the first HARQ feedback; the first control operation includes at least one of the following: in the first DRX downlink RTT timer... If a timeout occurs and downlink data is not received correctly, a second DRX retransmission timer is started; or the first DRX downlink retransmission timer is maintained or restarted. This enables the terminal to simultaneously send HARQ feedback from multiple HARQ processes according to network device instructions, or to retransmit HARQ feedback according to network device instructions, preventing the DRX downlink retransmission timer from being stopped or delayed. For HARQ processes that have already started the DRX downlink RTT timer or DRX downlink retransmission timer, retransmission scheduling can be obtained as early as possible, ensuring timely retransmission scheduling. This effectively solves the problem in existing technologies where retransmission scheduling cannot be performed in a timely manner due to non-continuous reception timer control schemes for special HARQ feedback types.

The first response feedback is a HARQ negative response feedback for the first HARQ process; or maintains or restarts the first DRX downlink retransmission timer; it can support the terminal to send HARQ feedback for multiple HARQ processes simultaneously according to the network device's instruction, or to retransmit HARQ feedback according to the network device's instruction, avoiding the DRX downlink retransmission timer being stopped or delayed. For HARQ processes that have started the DRX downlink RTT timer or DRX downlink retransmission timer, it can obtain retransmission scheduling as early as possible, realize the consistency of the network device and the terminal's understanding of the DRX status, and ensure the timely execution of retransmission scheduling (i.e., the network device can schedule data retransmission in a timely manner); it effectively solves the problem in the prior art where the non-continuous reception timer control scheme for special HARQ feedback types causes the retransmission scheduling to not be performed in a timely manner.

[0316] The discontinuous reception timer control device provided in this application embodiment performs a first control operation on at least one discontinuous reception DRX downlink retransmission timer corresponding to a first HARQ process after executing a first Hybrid Automatic Repeat Request (HARQ) feedback; wherein, the first HARQ feedback is a HARQ feedback triggered by downlink control information (DCI) scheduling; the first HARQ process refers to a HARQ process that has started a first DRX downlink round-trip timeout (RTT) timer or a first DRX downlink retransmission timer before executing the first HARQ feedback; the first control operation includes at least one of the following: in the first DRX downlink RTT... If the TT timer times out and downlink data is not received correctly, the second DRX retransmission timer is started; or the first DRX downlink retransmission timer is maintained or restarted.

For HARQ processes that have already started the DRX downlink RTT timer or DRX downlink retransmission timer, retransmission scheduling can be obtained as early as possible, ensuring timely retransmission scheduling. This effectively solves the problem in existing technologies where retransmission scheduling cannot be performed in a timely manner due to non-continuous reception timer control schemes for special HARQ feedback types.

[0317] The HARQ feedback triggered by the DCI scheduling includes at least one of the following: HARQ feedback of all current carriers and all HARQ processes fed back by the terminal at one time; or HARQ feedback of some carriers and / or some HARQ processes fed back by the terminal at one time; or HARQ feedback of the previous retransmission by the terminal.

[0319] The step of maintaining or restarting the first DRX downlink retransmission timer includes: if the first DRX downlink retransmission timer has already been started before the execution of the first HARQ feedback, continuing to run the first DRX downlink retransmission timer without starting the DRX downlink RTT timer corresponding to the first HARQ process; or, if the first DRX downlink retransmission timer has already been started before the execution of the first HARQ feedback, continuing to run the first DRX downlink retransmission timer and starting the third DRX downlink RTT timer; if the first DRX downlink retransmission timer times out and the downlink data packet is not received correctly, extending the duration of the DRX downlink retransmission timer; or, if the first DRX downlink retransmission timer has already been started before the execution of the first HARQ feedback and the downlink data packet is not received correctly, restarting the first DRX downlink retransmission timer.

[0320] In this embodiment of the application, extending the duration of the DRX downlink retransmission timer includes any one of the following: (1) starting the third DRX downlink retransmission timer when the third DRX downlink RTT timer times out; (2) setting the terminal to an active state during the time period between the first DRX downlink retransmission timer and the third DRX downlink retransmission timer, and starting the third DRX downlink retransmission timer when the third DRX downlink RTT timer times out; (3) extending the length of the first DRX downlink retransmission timer to the start time of the third DRX downlink retransmission timer; and starting the third DRX downlink retransmission timer when the third DRX downlink RTT timer times out; (4) extending the length of the first DRX downlink retransmission timer to a first length; the first length is equal to the sum of the first DRX downlink retransmission timer, the third DRX downlink retransmission timer, and the time interval, wherein the time interval is the time interval between the first DRX downlink retransmission timer and the third DRX downlink retransmission timer.
