[0036] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

[0038] Figure 1 is a schematic diagram of the architecture of a communication system provided by an embodiment of the present application. As shown in Figure 1, communication system 100 may include terminal device 110 and network device 120. Network device 120 may communicate with terminal device 110 via an air interface. Multi-service transmission is supported between terminal device 110 and network device 120.

[0039] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), or future communication systems.

[0040] In the communication system 100 shown in Figure 1, the network device 120 may be an access network device that communicates with the terminal device 110.

[0042] The terminal device 110 may be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.

It should be understood that SMF+PGW-C can simultaneously implement the functions that can be implemented by SMF and PGW-C. During the network evolution process, the above-mentioned core network device may also be called other names, or a new network entity may be formed by dividing the functions of the core network, which is not limited in the embodiments of the present application.

For example, predefined can refer to what is defined in the protocol. It should also be understood that in the embodiments of the present application, the “protocol” may refer to a standard protocol in the field of communications, such as LTE protocols, NR protocols, and related protocols used in future communication systems, and the present application does not limit this.

[0050] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0051] With the pursuit of speed, delay, high-speed mobility, energy efficiency and the diversity and complexity of services in future life, the 3GPP (3 rdThe 3GPP (3rd Generation Partnership Project) international standards organization has begun developing the fifth generation (5G). Key 5G application scenarios include enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (URLLC), and massive machine-type communication (mMTC).

[0052] In order to reduce air interface signaling and quickly restore wireless connections and data services in the 5G network environment, a new Radio Resource Control (RRC) state is defined, namely the connection inactive state (RRC_INACTIVE state). This state is different from the idle state (RRC_IDLE state) and the active state (RRC_ACTIVE state).

[0053] RRC_IDLE state: Mobility is based on UE cell selection and reselection, paging is initiated by the Core Network (CN), and the paging area is configured by the CN; there is no UE Access Stratum (AS) context on the base station side; and there is no RRC connection.

[0054] RRC_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.

[0055] RRC_INACTIVE state: Mobility is based on UE cell selection and reselection, there is a connection between the core network and the access network (CN-NR), the UE AS context exists on a base station, paging is triggered by the Radio Access Network (RAN), the RAN-based paging area is managed by the RAN, and the network side knows the UE location based on the RAN paging area level.

[0056] In NR, network equipment can configure the discontinuous reception (DRX) function for terminal devices, allowing the terminal to discontinuously monitor the physical downlink control channel (PDCCH) to save power for the terminal device. DRX is mainly used to control the MAC entity of the terminal device to monitor the cell radio network temporary identifier (C-RNTI), cancellation indication-RNTI (identification of cancellation in the uplink, CI-RNTI), configured scheduling radio network temporary identifier (Configured Scheduling RNTI, CS-RNTI), interruption RNTI (Interruption RNTI, INT-RNTI), slot format indication RNTI (Slot Format Indication RNTI, SFI-RNTI), semi-persistent channel state information RNTI (SemiPersistent channel state information RNTI, SP-CSI-RNTI), transmission power control (Transmit Power Control, TPC)-physical uplink control channel (Physical Uplink Control Channel, PUCCH)-RNTI, TPC-physical uplink shared channel (PUSCH)-RNTI, TPC-SRS-RNTI, AI-RNTI, SL-RNTI, SLCS-RNTI and SL semi-persistent scheduling V-RNTI.

[0057] The basic mechanism of DRX is to configure a DRX cycle for the terminal device. As shown in Figure 2, the DRX cycle consists of an active period (On Duration) and a dormant period (or inactive period) (Opportunity for DRX). During the On Duration, the terminal device monitors and receives the PDCCH; during the Opportunity for DRX, the terminal device does not receive downlink channel data to save power. As shown in Figure 2, in the time domain, time is divided into a series of continuous DRX cycles.

[0058] Each MAC entity has a DRX configuration. The DRX configuration parameters include:

[0059] DRX onDuration Timer (drx-onDurationTimer): specifies the continuous duration of monitoring PDCCH (i.e., the duration of the activation period) starting from the start subframe of the DRX cycle;

[0060] DRX slot offset (drx-SlotOffset): The delay for the UE to start the drx-onDurationTimer;

[0061] DRX inactivity timer (drx-InactivityTimer): indicates the duration of the UE's monitoring of the PDCCH after receiving a PDCCH indicating an initial uplink or downlink transmission, that is, the duration of the active period;

[0062] DRX downlink retransmission timer (drx-RetransmissionTimerDL): specifies the maximum duration that the terminal device monitors the PDCCH indicating downlink retransmission scheduling. Each downlink HARQ process except the broadcast process corresponds to one drx-RetransmissionTimerDL;

[0063] DRX uplink retransmission timer (drx-RetransmissionTimerUL): indicates the maximum duration that the terminal device monitors the PDCCH indicating uplink retransmission scheduling, where each uplink HARQ process corresponds to one drx-RetransmissionTimerUL;

[0064] DRX long cycle start offset (drx-LongCycleStartOffset): used to configure the long DRX cycle (Long DRX cycle), as well as the subframe offset of the start of the long DRX cycle and the short DRX cycle (Short DRX Cycle);

[0065] Short DRX Cycle is an optional configuration;

[0066] Short DRX cycle duration (drx-ShortCycle): The duration that the UE is in a Short DRX cycle (and does not receive any PDCCH). This is an optional configuration.

[0067] DRX HARQ downlink round-trip transmission time timer (drx-HARQ-RTT-TimerDL): The minimum waiting time required for the terminal device to receive the PDCCH indicating downlink scheduling. Each downlink HARQ process except the broadcast process corresponds to one drx-HARQ-RTT-TimerDL;

[0068] DRX HARQ uplink round-trip transmission time timer (drx-HARQ-RTT-TimerUL): The minimum waiting time required for the terminal device to receive the PDCCH indicating uplink scheduling. Each uplink HARQ process corresponds to one drx-HARQ-RTT-TimerUL.

[0069] If the terminal device is configured with DRX, it needs to monitor the PDCCH during the DRX activation period. The DRX activation period includes the following situations:

[0070] -Any of the five timers, drx-onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimerDL, drx-RetransmissionTimerUL, and random access contention resolution timer ra-ContentionResolutionTimer, is running.

[0071] - A Scheduling Request (SR) is sent on the Physical Uplink Control Channel (PUCCH) and is in a pending state.

[0072] - In a contention-based random access procedure, after successfully receiving a random access response, an initial transmission indicated by a PDCCH scrambled by a C-RNTI has not been received.

[0073] In the existing mechanism, DRX long DRX cycle is the default configuration, and DRX short DRX cycle is an optional configuration. For terminals configured with short DRX cycle, the current protocol specifies the conversion method between long DRX cycle and short DRX cycle. The details are as follows:

[0074] When any of the following conditions is met, the terminal uses the DRX short cycle:

[0075] drx-InactivityTimer times out;

[0076] The terminal receives a DRX Command MAC CE.

[0077] When any of the following conditions is met, the terminal uses the DRX long cycle:

[0078] drx-ShortCycleTimer times out;

[0079] The terminal receives a long DRX command MAC CE.

[0080] The terminal determines when to start the drx-onDurationTimer based on whether it is currently in a short DRX cycle or a long DRX cycle. The specific regulations are as follows:

[0081] If the Short DRX Cycle is used and the current subframe satisfies [(SFN×10)+subframe number]modulo(drx-ShortCycle)=(drx-StartOffset)modulo(drx-ShortCycle), or if the Long DRX Cycle is used and the current subframe satisfies [(SFN×10)+subframe number]modulo(drx-LongCycle)=drx-StartOffset, the drx-onDurationTimer is started drx-SlotOffset slots after the start of the current subframe.

[0082] The condition for the terminal to start or restart the drx-InactivityTimer is: if the terminal receives a PDCCH indicating downlink or uplink initial transmission, the terminal starts or restarts the drx-InactivityTimer.

[0083] The conditions for the terminal to start and stop drx-RetransmissionTimerDL are:

[0084] 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.

[0085] If the timer drx-HARQ-RTT-TimerDL corresponding to a certain HARQ process of the terminal times out and the decoding of the downlink data transmitted using this HARQ process is unsuccessful, the terminal starts the drx-RetransmissionTimerDL corresponding to this HARQ process.

[0086] The conditions for the terminal to start and stop drx-RetransmissionTimerUL are:

[0087] 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.

[0088] 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.

[0089] NR Multimedia Broadcast Service (MBS)

[0090] Traditional video software transmits data content via unicast, which can cause network congestion when too many users overload the network. When multiple users simultaneously watch video content within a wireless cell, the wireless downlink rate can become a bottleneck. In this case, broadcasting within the wireless cell ensures smooth viewing. The development of 5G NR MBS enables multimedia content to be delivered to mobile devices via broadcast, allowing users to watch broadcast programs and receive data push services anytime, anywhere.

[0091] In the physical layer design of Rel-17NR MBS, the MBS is called slightly differently depending on the connection state of the UE receiving the MBS. Multicast (or multicast) is when the network sends MBS services to a group of connected UEs. The base station sends a group-common PDCCH (CRC is scrambled using G-RNTI or G-CS-RNTI) to schedule the group-common PDSCH. Broadcast is when network equipment sends MBS services to UEs within coverage. The UE connection state can be connected or non-connected. The base station sends a group-common PDCCH (CRC is scrambled using MCCH-RNTI or G-RNTI) to schedule the group-common PDSCH.

[0092] For connected UEs, NR MBS multicast scheduling supports the following two transmission modes:

[0093] Point-to-Point (PTP) transmission mode: For a connected UE, the base station sends a dedicated PDCCH to the UE. The PDCCH CRC is scrambled with the UE-specific RNTI (such as C-RNTI). The UE-specific PDCCH is used to indicate the UE-specific PDSCH, and the indicated PDSCH is scrambled with the same UE-specific RNTI.

[0094] Point to Multi-point (PTM) transmission mode: For a group of connected UEs, the base station sends a group-common PDCCH to this group of UEs. The PDCCH CRC is scrambled with the group-common RNTI. The group-common PDCCH is used to schedule the group-common PDSCH, and the scheduled PDSCH is scrambled with the same group-common RNTI.

[0095] Among them, the PTP sending mode can only be used as the retransmission sending mode in MBS.

[0096] In an example, the PTP mode is shown in Figure 3. For UE301-1, UE301-2 and UE301-3, the base station 302 sends PDCCH303-1 using C-RNTIa, PDCCH303-2 using C-RNTIb, and PDCCH303-3 using C-RNTIc, respectively. Among them, PDCCH303-1 using C-RNTIa is used to schedule the PDSCH dedicated to UE301-1, PDCCH303-2 using C-RNTIb is used to schedule the PDSCH dedicated to UE301-2, and PDCCH I303-3 using C-RNTIc is used to schedule the PDSCH dedicated to UE301-3. The PDSCH dedicated to UE301-1 is scrambled using C-RNTIa, the PDSCH dedicated to UE301-2 is scrambled using C-RNTI b, and the PDSCH dedicated to UE301-3 is scrambled using C-RNTI c.

[0097] In one example, the PTM transmission mode is shown in Figure 4. For UE301-1, UE301-2 and UE301-3, the base station 302 sends a group common PDCCH (GC-PDCCH) to UE301-1, UE301-2 and UE301-3. The GC-PDCCH is encrypted with G-CNTI, and the GC-PDCCH is used to schedule GC-PDSCH. The GC-PDSCH is encrypted with G-RNTI.

[0098] The base station can configure two HARQ-ACK feedback modes for the connected UE, a first HARQ-ACK mode (positive response or negative response ((ACK / NACK)) and a second HARQ-ACK mode (only negative response (NACK-only)).

[0099] When the base station configures the first HARQ-ACK mode for the UE, it schedules the initial transmission of a TB for a group of UEs through the PTM transmission mode. Based on the feedback of each UE (ACK, NACK, or no feedback), the base station schedules the retransmission of this TB using the PTM transmission mode or the PTP transmission mode.

[0100] When the base station configures the second HARQ-ACK mode for the UE, it schedules the initial transmission of a TB for a group of UEs through PTM transmission mode 1. If one or more UEs feedback NACK, the base station uses PTM transmission mode 1 to schedule the retransmission of this TB.

[0101] DRX mechanism for MBS broadcast

[0102] Receiving broadcast service data also requires UE energy conservation, so broadcast MBS DRX is also supported. Broadcast MBS DRX is configured per G-RNTI, and is independent of each other, as well as from unicast DRX and multicast MBS DRX. The independence between broadcast MBS DRXs can be understood as the independence of MBS DRXs for different broadcast services.

[0103] The configuration parameters of broadcast MBS DRX include: drx-onDurationTimerPTM, drx-SlotOffsetPTM, drx-InactivityTimerPTM and drx-LongCycleStartOffsetPTM.

[0104] When [(SFN×10)+subframe number]modulo(drx-LongCycle-PTM)=drx-StartOffset-PTM, the timer drx-onDurationTimerPTM is started; when the downlink PDCCH scheduling is received, the timer drx-InactivityTimerPTM is started; for a certain G-RNTI, if the network has configured DRX for the G-RNTI, the PDCCH scrambled by the G-RNTI is monitored only when the timer drx-onDurationTimerPTM or drx-InacrivityTimerPTM is running.

[0105] DRX mechanism for MBS multicast

[0106] Receiving multicast service data also requires consideration of UE energy conservation, so multicast MBS DRX is also supported. Multicast MBS DRX is configured per G-RNTI / G-CS-RNTI, and is independent of each other and of unicast DRX.

[0107] Multicast MBS DRX configuration parameters include: drx-onDurationTimerPTM, drx-SlotOffsetPTM, drx-InactivityTimerPTM, drx-LongCycleStartOffsetPTM, drx-RetransmissionTimerDL-PTM, and drx-HARQ-RTT-TimerDL-PTM. Multicast DRX supports per-G-RNTI / G-CS-RNTI DRX commands. That is, DRX commands are transmitted scrambled by the G-RNTI and are used for the multicast MBS DRX corresponding to this G-RNTI.

[0108] For a certain G-RNTI, if the network configures DRX for the G-RNTI, the PDCCH scrambled by the G-RNTI is monitored only when the timer drx-onDurationTimerPTM, drx-InactivityTimerPTM, or drx-RetransmissionTimerDL-PTM is running.

[0109] The operation of DRX is similar to that of unicast DRX. However, in multicast MBS, the feedback of multicast service data reception introduces NACK-only HARQ feedback mode, HARQ feedback disabling mode, and PTP for transmitting PTM retransmissions, so multicast MBS DRX has its own particularities.

[0110] When the HARQ feedback disabling mode is used, the UE has no HARQ feedback, so the UE does not start the drx-HARQ-RTT-TimerDL-PTM timer and the drx-RetransmissionTimerDL-PTM timer.

[0111] When the NACK only HARQ feedback mode is used, if the received MAC PDU is decoded correctly, the UE does not have HARQ feedback, so the UE does not start the drx-HARQ-RTT-TimerDL-PTM timer and the drx-RetransmissionTimerDL-PTM timer.

[0112] When PTP is used to transmit PTM retransmission mode, if there is HARQ feedback, the UE is not sure whether the retransmitted data comes from PTM or PTP, so it starts the unicast drx-HARQ-RTT-TimerDL timer and the multicast MBS DRX drx-HARQ-RTT-TimerDL-PTM timer at the same time.

[0113] Connected WUS

[0114] In NR R16, a power saving signal, namely WUS, is introduced. The UE starts blind detection of the PDCCH-based power saving signalling (also called PDCCH-WUS) at the offset time before the start time of the drx-ondurationTimer corresponding to each long DRX cycle. If PDCCH-WUS is detected and the WUS indicates that the UE is to wake up, the UE starts the drx-ondurationTimer in the Long DRX cycle; if PDCCH-WUS is detected and the WUS indicates that the UE is not to wake up, the UE will not start the drx-ondurationTimer.

[0115] The aforementioned connected-state energy-saving technologies, including DRX and WUS, are designed for situations where the terminal's main receiver remains permanently on. Ultra-low power WUS (LP-WUS), a wake-up signal with lower power consumption, is more energy-efficient than the WUS mechanism. This uses a lower-power receiver, eliminating the main receiver. The terminal device activates the main receiver only after receiving LP-WUS to monitor downlink signals, achieving energy savings.

[0116] The operating principle of LP-WUS is shown in Figures 5 and 6. UE 200 includes a main radio (MR) 501 and a lower power wake-up receiver (LR) 502. The UE receives a wake-up signal indicating whether to turn off or on based on the LP wake-up receiver 502. As shown in Figure 5, when the LP wake-up receiver 502 receives a wake-up signal indicating off, the main receiver 501 remains off or in a deep sleep state. As shown in Figure 6, when the LP wake-up receiver 502 receives a wake-up signal indicating on, the LP wake-up main receiver 502 triggers the main receiver 501 to turn on.

[0117] After the introduction of the LP-WUS signal, its impact on connected UEs needs to be studied. Based on current understanding, the LP-WUS is used to restore the UE's primary receiver's monitoring of the PDCCH. For UEs that support and are configured for both unicast and MBS services, how to use LP-WUS to control their reception of these services is a question that needs to be studied.

[0118] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0119] An embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG7 , including:

[0120] S701. The terminal device receives a low-power wake-up signal LP-WUS sent by a network device. The LP-WUS is used to control the main receiver MR of the terminal device to monitor the first physical downlink control channel PDCCH and / or the second PDCCH. The first PDCCH is a PDCCH indicating unicast scheduling, and the second PDCCH is a PDCCH indicating multicast and / or broadcast scheduling.

[0121] The low-power wake-up receiver (LR) in the terminal device in the connected state monitors the LP-WUS sent by the network device. When the network device sends the LP-WUS to the terminal device, the LR of the terminal device receives the LP-WUS sent by the network device. The terminal device controls the MR to monitor the first PDCCH and / or the second PDCCH based on the LP-WUS received by the LR. The first PDCCH is used to indicate unicast scheduling, and the second PDCCH is used to indicate multicast and / or broadcast scheduling.

[0122] The first PDCCH indicating unicast scheduling can be understood as the first PDCCH being used to indicate the first PDSCH or the first PUSCH of a unicast service, or the first PDSCH or the first PUSCH being used to schedule a unicast service. The second PDCCH indicating multicast and / or broadcast scheduling can be understood as the second PDCCH indicating the second PDSCH of a multicast and / or broadcast service, or the second PDSCH being used to schedule a multicast and / or broadcast service.

[0123] In the embodiment of the present application, the first PDCCH and the first PDSCH or the first PUSCH scheduled by the first PDCCH are scrambled using the same RNTI. The RNTI used to scramble the first PDCCH may include a C-RNTI or a CS-RNTI.

[0124] In the embodiment of the present application, the second PDCCH and the second PDSCH are scrambled using the same or different RNTIs. The RNTI used to scramble the second PDCCH may include: G-RNTI or G-CS-RNTI.

[0125] In the embodiment of the present application, the LP-WUS is used to control the MR to monitor the first PDCCH and / or the second PDCCH, including one or more of the following monitoring scenarios:

[0126] Monitoring scenario 1: Control monitoring of the first PDCCH;

[0127] Monitoring scenario 2: Control monitoring of the second PDCCH;

[0128] Monitoring scenario three: controlling monitoring of the first PDCCH and controlling monitoring of the second PDCCH.

[0129] In monitoring scenario 1, the LP-WUS is used to resume the MR's monitoring of the first PDCCH, or to keep the MR from monitoring the first PDCCH, or to keep the MR monitoring the first PDCCH.

[0130] In monitoring scenario 2, the LP-WUS is used to resume the MR's monitoring of the second PDCCH, or to keep the MR from monitoring the second PDCCH, or to keep the MR monitoring the second PDCCH.

[0131] In monitoring scenario three, LP-WUS is used to simultaneously control monitoring of the first PDCCH and the second PDCCH. For the control of LP-WUS monitoring of the first PDCCH, refer to monitoring scenario one, and for the control of LP-WUS monitoring of the second PDCCH, refer to monitoring scenario two.

[0132] In an embodiment of the present application, when the terminal device receives the LP-WUS sent by the network device, the MR is controlled based on the received LP-WUS to monitor the PDCCH indicating unicast scheduling and / or the PDCCH indicating multicast and / or broadcast scheduling. After receiving the LP-WUS, the terminal device controls the monitoring of the PDCCH that schedules the corresponding service, thereby reducing the service delay while minimizing the power consumption of the terminal device.

[0133] Below, the wireless communication method provided in FIG. 7 of the embodiment of the present application is further described.

[0134] In some embodiments, the LP-WUS is used to control the MR to monitor the first PDCCH and the second PDCCH.

[0135] Here, the monitoring control mode of the LP-WUS for the first PDCCH and the second PDCCH is monitoring control mode 1: the LP-WUS controls the first PDCCH and the second PDCCH simultaneously. The LP-WUS received by the terminal device is used to control the first PDCCH and the second PDCCH simultaneously.

[0136] For monitoring control mode 1, the monitoring states (also referred to as monitoring behaviors) of the first PDCCH and the second PDCCH are controlled using the same LP-WUS. It is understandable that the default LP-WUS is for the first PDCCH and the second PDCCH.

[0137] In the monitoring control mode 1, the scenario in which the LP-WUS is used to control the MR to monitor the first PDCCH and / or the second PDCCH only includes monitoring scenario 1.

[0138] The LR of the terminal device receives the LP-WUS, and the terminal device controls the MR to monitor the first PDCCH and the second PDCCH based on the received LP-WUS.

[0139] In some embodiments, the LP-WUS indicating wake-up is used to wake up the MR to monitor the first PDCCH and the second PDCCH.

[0140] In the embodiment of the present application, the LP-WUS may or may not indicate wake-up. The LP-WUS indicating wake-up is used to wake up the MR to monitor the first PDCCH and the second PDCCH.

[0141] Optionally, the terminal device receives an LP-WUS that does not indicate wake-up, and maintains the monitoring status of the first PDCCH and the second PDCCH unchanged.

[0142] In some embodiments, the terminal device further implements:

[0143] Based on the LP-WUS indicating wake-up, the terminal device resumes the MR's monitoring of the first PDCCH and the second PDCCH.

[0144] When the LR of the terminal device receives the LP-WUS indicating wake-up, the LR sends a wake-up instruction to the MR, and the MR resumes monitoring of the first PDCCH and the second PDCCH simultaneously based on the wake-up instruction.

[0145] After the MR resumes monitoring of the first PDCCH and the second PDCCH, the terminal device can monitor the first PDCCH and the second PDCCH through the MR.

[0146] The terminal device can monitor the first PDCCH and the second PDCCH through the MR, which can be understood as the terminal device can monitor the first PDCCH and the second PDCCH based on a certain mechanism (such as the DRX mechanism), but it does not mean that the first PDCCH and the second PDCCH are always monitored.

[0147] Optionally, the terminal device monitors the first PDCCH during the activation period of unicast DRX, and monitors the second PDCCH during the activation period of multicast or broadcast DRX.

[0148] In some embodiments, the LP-WUS indicating awakening is further used to control the MR to enter an awake state from a sleep state, wherein the MR monitors the restoration of the first PDCCH and the second PDCCH in the awake state.

[0149] The states of MR include an awake state or a sleep state. The awake state can also be replaced by a working state, and the sleep state can also be replaced by a closed state, a light sleep state, or a deep sleep state.

[0150] When the LR of the terminal device receives an LP-WUS indicating wake-up, the LR sends a wake-up indication to the MR. The MR enters the wake-up state from the sleep state based on the received wake-up indication, and resumes monitoring of the first PDCCH and the second PDCCH in the wake-up state.

[0151] In some embodiments, the terminal device does not monitor the first PDCCH and the second PDCCH when the MR is in a sleep state.

[0152] Before the terminal device receives the LP-WUS indicating wake-up, the MR is in a sleep state and does not monitor the first PDCCH and the second PDCCH in the sleep state. When the terminal device receives the LP-WUS indicating wake-up, the MR enters the wake-up state based on the received LP-WUS indicating wake-up and resumes monitoring of the first PDCCH and the second PDCCH in the wake-up state.

[0153] In the embodiment of the present application, the same LP-WUS is used to simultaneously control the UE's MR to monitor the PDCCH indicating unicast scheduling and the PDCCH indicating multicast and / or broadcast scheduling, thereby controlling the monitoring of different PDCCHs through the same LP-WUS, thereby minimizing signaling overhead.

[0154] In some embodiments, the LP-WUS is used to control the MR to monitor the first PDCCH and / or the second PDCCH indicated by the LP-WUS.

[0155] Here, the monitoring control mode of the LP-WUS for the first PDCCH and the second PDCCH is monitoring control mode 2: the LP-WUS is used to control the monitoring of the first PDCCH and / or the second PDCCH indicated by itself.

[0156] In the second monitoring control mode, the LP-WUS may indicate one or both of the first PDCCH and the second PDCCH; the LP-WUS is used to control the MR to monitor the PDCCH indicated by the LP-WUS.

[0157] In an example, the LP-WUS indicates the first PDCCH, and the LP-WUS is used to control the MR to monitor the first PDCCH. In this case, the monitoring scenario is the first monitoring scenario.

[0158] In an example, the LP-WUS indicates the second PDCCH, and the LP-WUS is used to control the MR to monitor the second PDCCH. In this case, the monitoring scenario is the second monitoring scenario.

[0159] In an example, the LP-WUS indicates the first PDCCH and the second PDCCH. The LP-WUS is used to control the MR to monitor the first PDCCH and the second PDCCH. In this case, the monitoring scenario is monitoring scenario three.

[0160] In the embodiment of the present application, the LP-WUS may indicate the first PDCCH and / or the second PDCCH in a manner including but not limited to:

[0161] The LP-WUS carries the RNTI of the indicated first PDCCH and / or the RNTI of the second PDCCH;

[0162] The LP-WUS carries the service identifier corresponding to the indicated first PDCCH and / or the service identifier corresponding to the indicated second PDCCH.

[0163] For monitoring control mode 2, the monitoring status of the first PDCCH and the second PDCCH is controlled using the same LP-WUS. It can be understood that the LP-WUS is directed to the indicated first PDCCH and / or second PDCCH. The LP-WUS received by the terminal device can be used to control the monitoring of the first PDCCH and / or the second PDCCH, wherein the PDCCH targeted by the LP-WUS is the PDCCH indicated by the LP-WUS.

[0164] The LR of the terminal device receives the LP-WUS, and the terminal device controls the MR to monitor the first PDCCH and / or the second PDCCH indicated by the received LP-WUS based on the received LP-WUS.

[0165] In some embodiments, the LP-WUS indicating wake-up is used to wake up the MR to monitor the first PDCCH and / or the second PDCCH indicated by the LP-WUS.

[0166] In an embodiment of the present application, the LP-WUS may or may not indicate wake-up. For the LP-WUS that indicates wake-up, it is also used to indicate the first PDCCH and / or the second PDCCH, and the LP-WUS is used to wake up the MR to monitor the first PDCCH and / or the second PDCCH indicated by the LP-WUS.

[0167] Optionally, the terminal device receives an LP-WUS that does not indicate wake-up, and maintains the monitoring state of the first PDCCH and / or the second PDCCH unchanged.

[0168] In some embodiments, the terminal device further implements:

[0169] Based on the LP-WUS indicating wake-up, the terminal device resumes the MR's monitoring of the first PDCCH and / or the second PDCCH indicated by the LP-WUS.

[0170] When the LR of the terminal device receives the LP-WUS indicating wake-up, the LR sends a wake-up indication to the MR, and the MR resumes monitoring of the first PDCCH and / or the second PDCCH indicated by the LP-WUS based on the wake-up indication.

[0171] Based on the different PDCCHs indicated by LP-WUS, MR wake-up is divided into the following situations:

[0172] Case 1: If the LP-WUS indicates the first PDCCH, based on the LP-WUS indicating wakeup, the terminal device resumes the MR's monitoring of the first PDCCH;

[0173] Case 2: If the LP-WUS indicates the second PDCCH, based on the LP-WUS indicating wake-up, the terminal device resumes the MR's monitoring of the second PDCCH;

[0174] Case 3: If the LP-WUS indicates the first PDCCH and the second PDCCH, based on the LP-WUS indicating wake-up, the terminal device resumes the MR's monitoring of the first PDCCH and the second PDCCH.

[0175] For case 1, the LP-WUS indicates the first PDCCH, and the MR resumes monitoring of the first PDCCH based on the wake-up indication.

[0176] After the MR of the terminal device resumes monitoring of the first PDCCH, it can monitor the first PDCCH through the MR.

[0177] The fact that the terminal device can monitor the first PDCCH through the MR can be understood as the terminal device can monitor the first PDCCH based on a certain mechanism (such as the DRX mechanism), but it does not mean that the terminal device monitors the first PDCCH all the time.

[0178] Optionally, the terminal device monitors the first PDCCH during the activation period of unicast DRX.

[0179] In some embodiments, the monitoring state of the second PDCCH remains unchanged.

[0180] If the LP-WUS received by the terminal device indicates the first PDCCH, it can be understood that the LP-WUS does not indicate the second PDCCH, the LP-WUS does not control the second PDCCH, and the terminal device maintains the monitoring state of the second PDCCH unchanged.

[0181] In one example, before receiving the LP-WUS, the monitoring state of the second PDCCH of the terminal device is monitoring. After receiving the LP-WUS, the MR of the terminal device resumes monitoring of the first PDCCH and maintains monitoring of the second PDCCH.

[0182] In one example, before receiving the LP-WUS, the terminal device's monitoring state for the second PDCCH is non-monitoring. After receiving the LP-WUS, the MR of the terminal device resumes monitoring the first PDCCH and remains non-monitoring the second PDCCH.

[0183] For case 2, the LP-WUS indicates the second PDCCH, and the MR resumes monitoring the second PDCCH based on the wake-up indication.

[0184] After the MR of the terminal device resumes monitoring of the second PDCCH, it can monitor the second PDCCH through the MR.

[0185] The fact that the terminal device can monitor the second PDCCH through the MR can be understood as the terminal device can monitor the second PDCCH based on a certain mechanism (such as the DRX mechanism), but it does not mean that the terminal device monitors the second PDCCH all the time.

[0186] Optionally, the terminal device monitors the second PDCCH during the activation period of multicast or broadcast DRX.

[0187] In some embodiments, the monitoring state of the first PDCCH remains unchanged.

[0188] If the LP-WUS received by the terminal device indicates the second PDCCH, it can be understood that the LP-WUS does not indicate the first PDCCH, the LP-WUS does not control the first PDCCH, and the terminal device maintains the monitoring state of the first PDCCH unchanged.

[0189] In one example, before receiving the LP-WUS, the terminal device's monitoring state of the first PDCCH is monitoring. After receiving the LP-WUS, the MR of the terminal device resumes monitoring of the second PDCCH and maintains monitoring of the first PDCCH.

[0190] In one example, before receiving the LP-WUS, the terminal device monitors the first PDCCH in a non-monitoring state. After receiving the LP-WUS, the MR of the terminal device resumes monitoring the second PDCCH and remains non-monitoring the first PDCCH.

[0191] For case three, the LP-WUS indicates the first PDCCH and the second PDCCH, and the MR resumes monitoring of the first PDCCH and the second PDCCH based on the wake-up indication.

[0192] After the MR of the terminal device resumes monitoring of the first PDCCH and the second PDCCH, the terminal device can monitor the first PDCCH and the second PDCCH through the MR.

[0193] The fact that the terminal device can monitor the first PDCCH and the second PDCCH through the MR can be understood as the fact that the terminal device can monitor the first PDCCH and the second PDCCH based on a certain mechanism (such as a DRX mechanism).

[0194] Optionally, the terminal device monitors the first PDCCH during the activation period of unicast DRX, and monitors the second PDCCH during the activation period of multicast or broadcast DRX.

[0195] In some embodiments, the LP-WUS for indicating wake-up is further used to control the MR to enter an awake state from a sleep state, wherein the MR monitors the first PDCCH and / or the second PDCCH in the awake state.

[0196] When the LR of the terminal device receives an LP-WUS indicating wake-up, the LR sends a wake-up indication to the MR. The MR enters the wake-up state from the sleep state based on the received wake-up indication, and resumes monitoring of the first PDCCH and / or the second PDCCH indicated by the LP-WUS in the wake-up state.

[0197] In some embodiments, the terminal device does not monitor the first PDCCH and / or the second PDCCH when the MR is in a sleep state.

[0198] Before the terminal device receives the LP-WUS indicating wake-up, the MR is in a sleep state and does not monitor the first PDCCH and / or the second PDCCH in the sleep state. When the terminal device receives the LP-WUS indicating wake-up, the MR enters the wake-up state based on the received LP-WUS indicating wake-up, and resumes monitoring of the first PDCCH and / or the second PDCCH indicated by the LP-WUS in the wake-up state.

[0199] In the embodiment of the present application, the behavior of the MR of the terminal device in the sleep state includes the following situations:

[0200] Monitoring situation 1: neither monitoring the first PDCCH nor monitoring the second PDCCH;

[0201] Monitoring situation 2: Do not monitor the first PDCCH, but monitor the second PDCCH;

[0202] Monitoring situation 3: monitoring the first PDCCH and not monitoring the second PDCCH.

[0203] In some embodiments, if the LP-WUS indicates the second PDCCH, the LP-WUS indicates one or more of the following:

[0204] a PDCCH indicating multicast scheduling and / or a PDCCH indicating broadcast scheduling;

[0205] The RNTI scrambled PDCCH indicates multicast or broadcast scheduling.

[0206] In an embodiment of the present application, for different second PDCCHs, the division method may include: division based on multicast and broadcast and / or division based on different RNTIs. When the division method includes division based on multicast and broadcast, the LP-WUS separately indicates the PDCCH indicating multicast scheduling and the PDCCH indicating broadcast. When the division method includes division based on RNTI, the LP-WUS separately indicates the PDCCH indicating multicast scheduling and / or broadcast scheduling that are scrambled by different RNTIs.

[0207] In one example, the second PDCCH indicated by the LP-WUS includes: a PDCCH indicating multicast scheduling and / or a PDCCH indicating broadcast scheduling, and the terminal device resumes MR monitoring of the PDCCH indicating multicast scheduling and / or the PDCCH indicating broadcast scheduling.

[0208] In one example, the second PDCCH indicated by the LP-WUS includes one or more RNTI1-scrambled PDCCHs indicating multicast or broadcast scheduling, and the terminal device resumes MR monitoring of one or more RNTI1-scrambled PDCCHs indicating multicast or broadcast scheduling.

[0209] In one example, the second PDCCH indicated by the LP-WUS includes: a PDCCH indicating multicast scheduling and one or more RNTI-scrambled PDCCHs indicating broadcast scheduling, then the terminal device resumes MR's monitoring of the PDCCH indicating multicast scheduling and one or more RNTI-scrambled PDCCHs indicating broadcast scheduling.

[0210] In one example, the second PDCCH indicated by the LP-WUS includes: a PDCCH indicating broadcast scheduling and one or more RNTI1-scrambled PDCCHs indicating multicast scheduling, then the terminal device resumes MR's monitoring of the PDCCH indicating broadcast scheduling and one or more RNTI1-scrambled PDCCHs indicating multicast scheduling.

[0211] In an embodiment of the present application, when one or more LP-WUSs monitor the PDCCH indicating unicast scheduling and the PDCCH indicating multicast and / or broadcast scheduling, different PDCCHs can be controlled by the same LP-WUS, or each PDCCH can be controlled separately by a different LP-WUS, thereby improving the control flexibility of PDCCH monitoring.

[0212] In some embodiments, if the LP-WUS is used to control the MR's monitoring of the first PDCCH and the second PDCCH, or the LP-WUS is used to control the MR's monitoring of the first PDCCH and / or the second PDCCH indicated by the LP-WUS, the terminal device further performs:

[0213] The terminal device receives first configuration information configured by the network device, where the first configuration information is used for monitoring of the LP-WUS.

[0214] In monitoring control mode 1 or monitoring control mode 2, the monitoring of the first PDCCH and the second PDCCH uses the same LP-WUS control, the network device configures first configuration information to the terminal device, the first configuration information is used for monitoring the LP-WUS, and the terminal device monitors the LP-WUS based on the first configuration information.

[0215] Optionally, the first configuration information may include: LP-WUS monitoring resource configuration.

[0216] In some embodiments, the LP-WUS is used to control the MR to monitor a target PDCCH corresponding to the LP-WUS, where the target PDCCH is the first PDCCH or the second PDCCH.

[0217] Here, the monitoring control mode of the LP-WUS for the first PDCCH and the second PDCCH is monitoring control mode three: different LP-WUSs are used to monitor the corresponding first PDCCH or second PDCCH.

[0218] In monitoring control mode three, the PDCCH corresponding to the LP-WUS received by the terminal device is called a target PDCCH, wherein the target PDCCH is or belongs to the first PDCCH or the second PDCCH.

[0219] In one example, the LP-WUS corresponds to the first PDCCH, and the LP-WUS is used to control the MR to monitor the first PDCCH. In this case, the monitoring scenario is monitoring scenario one.

[0220] In one example, the LP-WUS corresponds to the second PDCCH, and the LP-WUS is used to control the MR to monitor the second PDCCH. In this case, the monitoring scenario is monitoring scenario two.

[0221] The first PDCCH and the second PDCCH correspond to different LP-WUSs, respectively. It is understandable that the monitoring of the first PDCCH and the second PDCCH is controlled by using the LP-WUS corresponding to each PDCCH, respectively. Each LP-WUS is used to control the monitoring of the corresponding PDCCH.

[0222] In the embodiment of the present application, the PDCCH corresponding to the LP-WUS can be understood as the PDCCH associated with the LP-WUS, and the terminal device can establish an association relationship between the LP-WUS and the PDCCH.

[0223] In an embodiment of the present application, the terminal device may determine the target PDCCH corresponding to the received LP-WUS based on the resource or LP-WUS sequence of the received LP-WUS, and may also carry indication information indicating the target PDCCH in the received LP-WUS, such as: the RNTI of the scrambled target PDCCH, the channel identifier for identifying the target PDCCH, etc.

[0224] For monitoring control mode 3, the LP-WUS received by the terminal device is used to control a PDCCH.

[0225] In some embodiments, the LP-WUS is one of a plurality of LP-WUSs, the plurality of LP-WUSs comprising:

[0226] a first LP-WUS, where the first LP-WUS is used to control the MR to monitor the first PDCCH;

[0227] One or more second LP-WUSs, where the second LP-WUSs are used to control the MR to monitor the second PDCCH.

[0228] In an embodiment of the present application, the first LP-WUS corresponds to the first PDCCH and is used to control the MR to monitor the first PDCCH. The second LP-WUS corresponds to the second PDCCH and is used to control the MR to monitor the second PDCCH. There are one or more second LP-WUSs, and different second LP-WUSs are used to control the MR to monitor different second PDCCHs.

[0229] In some embodiments, a different second LP-WUS among the plurality of second LP-WUSs is used to:

[0230] Controlling monitoring of a PDCCH indicating multicast scheduling or a PDCCH indicating broadcast scheduling; or,

[0231] Controls the monitoring of PDCCHs scrambled by different RNTIs and indicating multicast or broadcast scheduling.

[0232] In an embodiment of the present application, for different second PDCCHs, the division method may include: division based on multicast and broadcast and / or division based on different RNTIs. When the division method includes division based on multicast and broadcast, the LP-WUS separately indicates the PDCCH indicating multicast scheduling and the PDCCH indicating broadcast. When the division method includes division based on RNTI, the LP-WUS separately indicates the PDCCH indicating multicast scheduling and / or broadcast scheduling that are scrambled by different RNTIs.

[0233] The second LP-WUS may be an LP-WUS corresponding to a second PDCCH divided based on multicast or broadcast, and the second LP-WUS is used to control monitoring of a PDCCH indicating multicast scheduling or a PDCCH indicating broadcast scheduling.

[0234] In one example, the second LP-WUS received by the terminal device is used to control monitoring of the PDCCH indicating multicast scheduling, and the terminal device controls monitoring of the PDCCH indicating multicast scheduling based on the second LP-WUS.

[0235] In one example, the second LP-WUS received by the terminal device is used to control monitoring of the PDCCH indicating broadcast scheduling, and the terminal device controls monitoring of the PDCCH indicating broadcast scheduling based on the second LP-WUS.

[0236] The second LP-WUS may be an LP-WUS corresponding to a second PDCCH divided based on the RNTI, and the second LP-WUS is used to control monitoring of the RNTI-scrambled PDCCH indicating multicast or broadcast scheduling.

[0237] In one example, the second LP-WUS received by the terminal device is used to control the monitoring of the PDCCH indicating multicast / broadcast scheduling encrypted by the first RNTI, and the terminal device controls the monitoring of the PDCCH indicating multicast / broadcast scheduling encrypted by the first RNTI based on the second LP-WUS.

[0238] In one example, the second LP-WUS received by the terminal device is used to control the monitoring of the PDCCH indicating multicast / broadcast scheduling encrypted by the second RNTI, and the terminal device controls the monitoring of the PDCCH indicating multicast / broadcast scheduling encrypted by the second RNTI based on the second LP-WUS.

[0239] In some embodiments, the LP-WUS indicating wake-up is used to wake up the MR to monitor the target PDCCH corresponding to the LP-WUS.

[0240] In an embodiment of the present application, the LP-WUS may or may not indicate wake-up. For the LP-WUS that indicates wake-up, it is also used to indicate the first PDCCH or the second PDCCH, and the LP-WUS is used to wake up the MR to monitor the first PDCCH or the second PDCCH corresponding to the LP-WUS.

[0241] In some embodiments, the terminal device further implements:

[0242] Based on the LP-WUS indicating wake-up, the terminal device resumes the MR's monitoring of the target PDCCH.

[0243] When the LR of the terminal device receives the LP-WUS indicating wake-up, the LR sends a wake-up indication to the MR, and the MR resumes monitoring of the first PDCCH or the second PDCCH corresponding to the LP-WUS based on the wake-up indication.

[0244] Based on the different PDCCHs corresponding to LP-WUS, MR wake-up is divided into the following situations:

[0245] Case 4: if the LP-WUS is the first LP-WUS corresponding to the first PDCCH, based on the first LP-WUS indicating wake-up, the terminal device resumes the MR's monitoring of the first PDCCH;

[0246] Case 5: If the LP-WUS is the second LP-WUS corresponding to the second PDCCH, based on the second LP-WUS indicating wake-up, the terminal device resumes the MR's monitoring of the second PDCCH.

[0247] For case 4, the LP-WUS received by the terminal device is the first LP-WUS corresponding to the first PDCCH, and the MR resumes monitoring of the first PDCCH based on the wake-up indication.

[0248] After the MR of the terminal device resumes monitoring of the first PDCCH, it can monitor the first PDCCH through the MR.

[0249] The fact that the terminal device can monitor the first PDCCH through the MR can be understood as the fact that the terminal device can monitor the first PDCCH based on a certain mechanism (such as a DRX mechanism).

[0250] Optionally, the terminal device monitors the first PDCCH during the activation period of unicast DRX.

[0251] In some embodiments, the monitoring state of the second PDCCH remains unchanged.

[0252] If the terminal device receives the first LP-WUS, the terminal device maintains the monitoring state of the second PDCCH unchanged.

[0253] For case five, the LP-WUS received by the terminal device is the second LP-WUS corresponding to the second PDCCH, and the MR resumes monitoring of the second PDCCH based on the wake-up indication.

[0254] After the MR of the terminal device resumes monitoring of the second PDCCH, it can monitor the second PDCCH through the MR.

[0255] The fact that the terminal device can monitor the second PDCCH through the MR can be understood as the fact that the terminal device can monitor the second PDCCH based on a certain mechanism (eg, a DRX mechanism).

[0256] Optionally, the terminal device monitors the second PDCCH during an activation period in broadcast or multicast DRX.

[0257] In some embodiments, the monitoring state of the first PDCCH remains unchanged.

[0258] If the terminal device receives the second LP-WUS, the terminal device maintains the monitoring state of the first PDCCH unchanged.

[0259] Optionally, if the second PDCCH corresponding to the second LP-WUS is a PDCCH indicating multicast scheduling, the monitoring state of the PDCCH indicating broadcast scheduling remains unchanged.

[0260] When the second LP-WUS received by the terminal device corresponds to the PDCCH indicating multicast scheduling, the terminal device resumes the MR's monitoring of the PDCCH indicating multicast scheduling and maintains the monitoring state of the PDCCH indicating broadcast scheduling unchanged.

[0261] Optionally, if the second PDCCH corresponding to the second LP-WUS is a PDCCH indicating broadcast scheduling, the monitoring state of the PDCCH indicating multicast scheduling remains unchanged.

[0262] When the second LP-WUS received by the terminal device corresponds to the PDCCH indicating broadcast scheduling, the terminal device resumes the MR's monitoring of the PDCCH indicating broadcast scheduling and maintains the monitoring state of the PDCCH indicating multicast scheduling unchanged.

[0263] Optionally, if the second PDCCH corresponding to the second LP-WUS is a PDCCH scrambled by the first RNTI and indicating multicast or broadcast scheduling, the monitoring state of the PDCCH scrambled by the second RNTI and indicating multicast or broadcast scheduling remains unchanged.

[0264] When the second LP-WUS received by the terminal device is the LP-WUS corresponding to the second PDCCH divided based on RNTI, and the second LP-WUS currently received corresponds to the PDCCH indicating multicast or broadcast scheduling encrypted by the first RNTI, the MR is restored to monitor the PDCCH indicating multicast or broadcast scheduling encrypted by the first RNTI, and the monitoring state of the PDCCH indicating multicast or broadcast scheduling encrypted by the second RNTI is maintained.

[0265] It is understandable that the first RNTI and the second RNTI are two different RNTIs used to scramble the PDCCH indicating multicast or broadcast scheduling. The first RNTI is the RNTI scrambled by the PDCCH corresponding to the second LP-WUS received by the terminal device, and the second RNTI is any RNTI other than the first RNTI.

[0266] In some embodiments, the LP-WUS for indicating awakening is further used to control the MR to enter an awake state from a sleep state, wherein the MR monitors a target PDCCH corresponding to the LP-WUS in the awake state.

[0267] When the LR of the terminal device receives an LP-WUS indicating wake-up, the LR sends a wake-up indication to the MR. The MR enters the wake-up state from the sleep state based on the received wake-up indication, and resumes monitoring the target PDCCH corresponding to the LP-WUS in the wake-up state.

[0268] In the embodiment of the present application, different LP-WUSs are used to separately control the monitoring of PDCCHs indicating unicast scheduling and PDCCHs indicating multicast and / or broadcast scheduling, and the monitoring of different PDCCHs is controlled independently, thereby improving the flexibility of PDCCH monitoring control.

[0269] In some embodiments, when the MR is in a sleep state, the terminal device does not monitor the first PDCCH and / or the second PDCCH.

[0270] In some embodiments, if the LP-WUS is used to control the MR to monitor the target PDCCH corresponding to the LP-WUS, the terminal device further performs:

[0271] The terminal device receives a plurality of second configuration information configured by the network device, where the plurality of second configuration information is used for monitoring of the plurality of LP-WUSs.

[0272] In monitoring control mode three, the monitoring of the first PDCCH and the second PDCCH is controlled by different LP-WUSs, and different second PDCCHs are controlled by different LP-WUSs. The network device configures multiple second configuration information for the terminal device, and different second configuration information is used to monitor the LP-WUS corresponding to different PDCCHs. The terminal device then monitors the LP-WUS corresponding to each PDCCH based on the multiple second configuration information. The different PDCCHs here can be understood as the first PDCCH and the second PDCCH, or different second PDCCHs.

[0273] Optionally, the second configuration information may include one or more of the following: LP-WUS monitoring resource configuration, LP-WUS sequence (LP-WUS code). The second configuration may also be used for the terminal device to identify different LP-WUSs.

[0274] In some embodiments, the manner of resuming the MR's monitoring of the first PDCCH includes at least one of the following:

[0275] Recovery method 1: Start the discontinuous reception duration timer corresponding to unicast discontinuous reception DRX;

[0276] Recovery mode 2: monitoring a wake-up signal when the LP-WUS for recovering the first PDCCH is received, and starting a discontinuous reception duration timer corresponding to unicast DRX when the wake-up signal is monitored;

[0277] Recovery mode 3: starting a first timer corresponding to unicast DRX, and during the running of the first timer, the terminal device is in an active period of unicast DRX;

[0278] Recovery method 4: Entering the unicast DRX activation period.

[0279] In recovery mode 1, the terminal device waits for the start time of the discontinuous reception duration timer (drx-onDurationTimer) based on the unicast DRX parameters, and starts the drx-onDurationTimer at the start time to enter the unicast DRX activation period.

[0280] In recovery mode 2, the terminal device monitors the wake-up signal (WUS), also known as the (DCI with CRC scrambled by PS-RNTI, DCP) signal, and determines whether to start the drx-onDurationTimer corresponding to unicast DRX based on the reception status of the WUS.

[0281] In recovery mode 3, a first timer is set, and during the running time of the first timer, the unicast DRX of the terminal device is in an active period. The first timer can be a timer defined in the protocol such as drx-InactivityTimer or a custom timer.

[0282] In recovery mode 4, the terminal device directly enters the activation period of unicast DRX.

[0283] In some embodiments, a manner of resuming the monitoring of the second PDCCH by the MR includes one of the following:

[0284] Recovery method 5: Start the discontinuous reception duration timer corresponding to multicast or broadcast discontinuous reception DRX;

[0285] Recovery mode 6: starting a second timer corresponding to multicast or broadcast DRX, and during the running of the second timer, the terminal device is in an activation period of multicast or broadcast DRX;

[0286] Recovery method 7: Entering the activation period of multicast or broadcast DRX.

[0287] In recovery mode 5, the terminal device waits for the start time of the PTM discontinuous reception duration timer (drx-onDurationTimerPTM) based on the multicast or broadcast DRX parameters, and starts the drx-onDurationTimerPTM at the start time to enter the activation period of multicast or broadcast DRX.

[0288] In recovery mode 6, a second timer is set. During the running time of the second timer, the multicast or broadcast DRX of the terminal device is in the active period. The second timer can be a timer defined in the protocol such as drx-InactivityTimerPTM or a custom timer.

[0289] In recovery mode 7, the terminal device directly enters the activation period of multicast or broadcast DRX.

[0290] In some embodiments, the LP-WUS is used to control the MR of the terminal device to monitor the first PDCCH and / or the second PDCCH after a first time offset of a first time, where the first time is the time when the LP-WUS is received.

[0291] After a first time offset after receiving the LP-WUS, the terminal device controls the MR to monitor the first PDCCH and / or the second PDCCH based on the received LP-WUS.

[0292] An embodiment of the present application provides a wireless communication method, which is applied to a network device, as shown in FIG8 , including:

[0293] S801. The network device sends a low-power wake-up signal LP-WUS to the terminal device, where the LP-WUS is used to control the sending of a first PDCCH and / or a second PDCCH to the terminal device. The first PDCCH is a PDCCH indicating unicast scheduling, and the second PDCCH is a PDCCH indicating multicast and / or broadcast scheduling.

[0294] The network device sends an LP-WUS to a terminal device in a connected state, thereby controlling the terminal device's MR to monitor the first PDCCH and / or the second PDCCH through the sent LP-WUS, and also controlling the network device to send the first PDCCH and / or the second PDCCH. The first PDCCH is used to indicate unicast scheduling, and the second PDCCH is used to indicate multicast and / or broadcast scheduling.

[0295] The first PDCCH indicating unicast scheduling can be understood as the first PDCCH being the first PDSCH or the first PUSCH sent to the terminal device for indicating a unicast service, or the first PDSCH or the first PUSCH for scheduling a unicast service. The second PDCCH indicating multicast and / or broadcast scheduling can be understood as the second PDCCH being the second PDSCH sent to the terminal device for indicating a multicast and / or broadcast service, or the second PDSCH sent to the terminal device for scheduling a multicast and / or broadcast service.

[0296] In the embodiment of the present application, the LP-WUS is used to control the network device to send the first PDCCH and / or the second PDCCH, including one or more of the following sending scenarios:

[0297] Transmission scenario 1: Control the transmission of the first PDCCH;

[0298] Transmission scenario 2: Control the transmission of the second PDCCH;

[0299] Transmission scenario three: controlling the transmission of the first PDCCH and controlling the transmission of the second PDCCH.

[0300] In the first transmission scenario, the LP-WUS is used to resume the transmission of the first PDCCH, or to keep the first PDCCH from being transmitted, or to keep the first PDCCH from being transmitted.

[0301] In the second transmission scenario, the LP-WUS is used to resume the transmission of the second PDCCH, or to keep the second PDCCH from being transmitted, or to keep the second PDCCH from being transmitted.

[0302] In transmission scenario three, LP-WUS is used to simultaneously control the transmission of the first PDCCH and the second PDCCH. The control of the transmission of the first PDCCH by LP-WUS can be referred to in transmission scenario one, and the control of the transmission of the second PDCCH by LP-WUS can be referred to in transmission scenario two.

[0303] In an embodiment of the present application, when a network device sends an LP-WUS to a terminal device, the sending of a PDCCH indicating unicast scheduling and / or a PDCCH indicating multicast and / or broadcast scheduling is controlled based on the sent LP-WUS, so that the network device can send the LP-WUS according to the service transmission requirements of unicast and multicast / broadcast.

[0304] Below, the wireless communication method provided in FIG. 8 of the embodiment of the present application is further described.

[0305] In some embodiments, the LP-WUS is used to control the transmission of the first PDCCH and the second PDCCH.

[0306] Here, the transmission control mode of the LP-WUS for the first PDCCH and the second PDCCH is transmission control mode 1: the LP-WUS controls the first PDCCH and the second PDCCH simultaneously. The LP-WUS sent by the network device is used to control the first PDCCH and the second PDCCH simultaneously.

[0307] For the first transmission control mode, the transmission states (also referred to as transmission behaviors) of the first PDCCH and the second PDCCH are controlled using the same LP-WUS. It is understandable that the default LP-WUS is for the first PDCCH and the second PDCCH.

[0308] In the transmission control mode 1, the scenario in which the LP-WUS is used to transmit the first PDCCH and / or the second PDCCH only includes transmission scenario 1.

[0309] The network device controls transmission of the first PDCCH and the second PDCCH based on the transmitted LP-WUS.

[0310] In some embodiments, the LP-WUS indicating wake-up is used to indicate resumption of transmission of the first PDCCH and the second PDCCH.

[0311] In the embodiment of the present application, the LP-WUS may or may not indicate wake-up. The LP-WUS indicating wake-up is used to wake up the MR to monitor the first PDCCH and the second PDCCH.

[0312] Optionally, the network device sends an LP-WUS that does not indicate wake-up, and keeps or maintains the sending status of the first PDCCH and the second PDCCH unchanged.

[0313] In some embodiments, the network device further implements:

[0314] Based on the LP-WUS indicating wake-up, the network device resumes transmission of the first PDCCH and the second PDCCH.

[0315] The network device simultaneously resumes transmission of the first PDCCH and the second PDCCH based on the transmitted LP-WUS.

[0316] After the network device resumes sending the first PDCCH and the second PDCCH, it can send the first PDCCH and the second PDCCH.

[0317] The network device being able to send the first PDCCH and the second PDCCH can be understood as the network device being able to send the first PDCCH and the second PDCCH based on a certain mechanism (such as a DRX mechanism), but does not mean that the first PDCCH and the second PDCCH are always sent.

[0318] Optionally, the network device monitors the first PDCCH during an activation period of unicast DRX, and monitors the second PDCCH during an activation period of multicast or broadcast DRX.

[0319] In some embodiments, the network device does not send the first PDCCH and the second PDCCH to the terminal device before resuming sending of the first PDCCH and the second PDCCH.

[0320] The network device does not send the first PDCCH and the second PDCCH before sending the LP-WUS. When sending the LP-WUS indicating wakeup, the network device resumes sending the first PDCCH and the second PDCCH based on the sent LP-WUS indicating wakeup.

[0321] In an embodiment of the present application, the same LP-WUS is used to simultaneously control the transmission of the PDCCH indicating unicast scheduling and the PDCCH indicating multicast and / or broadcast scheduling, thereby controlling the terminal device to monitor different PDCCHs through the same LP-WUS, thereby minimizing the signaling overhead.

[0322] In some embodiments, the LP-WUS is used to control the transmission of the first PDCCH and / or the second PDCCH indicated by the LP-WUS.

[0323] Here, the transmission control mode of the LP-WUS for the first PDCCH and the second PDCCH is transmission control mode 2: the LP-WUS is used to control the transmission of the first PDCCH and / or the second PDCCH indicated by itself.

[0324] In the second transmission control mode, the LP-WUS may indicate one or both of the first PDCCH and the second PDCCH; the LP-WUS is used to control the transmission of the PDCCH indicated by the LP-WUS.

[0325] In one example, the LP-WUS indicates the first PDCCH, and the LP-WUS is used to control the transmission of the first PDCCH. At this time, the transmission scenario is transmission scenario one.

[0326] In one example, the LP-WUS indicates the second PDCCH, and the LP-WUS is used to control the transmission of the second PDCCH. At this time, the transmission scenario is the second transmission scenario.

[0327] In one example, the LP-WUS indicates the first PDCCH and the second PDCCH, and the LP-WUS is used to control the transmission of the first PDCCH and the second PDCCH. At this time, the transmission scenario is transmission scenario three.

[0328] In the embodiment of the present application, the LP-WUS may indicate the first PDCCH and / or the second PDCCH in a manner including but not limited to:

[0329] The LP-WUS carries the RNTI of the indicated first PDCCH and / or the RNTI of the second PDCCH;

[0330] The LP-WUS carries the service identifier corresponding to the indicated first PDCCH and / or the service identifier corresponding to the indicated second PDCCH.

[0331] For transmission control mode 2, the transmission status of the first PDCCH and the second PDCCH are controlled using the same LP-WUS. It is understandable that the LP-WUS is directed to the indicated first PDCCH and / or second PDCCH. The LP-WUS sent by the network device can be used to control the transmission of the first PDCCH and / or the second PDCCH, wherein the PDCCH targeted by the LP-WUS is the PDCCH indicated by the LP-WUS.

[0332] In some embodiments, the LP-WUS indicating wake-up is used to resume transmission of the first PDCCH and / or the second PDCCH indicated by the LP-WUS.

[0333] In an embodiment of the present application, the LP-WUS may or may not indicate wake-up. For the LP-WUS that indicates wake-up, it is also used to indicate the first PDCCH and / or the second PDCCH, and the LP-WUS is used to wake up the MR to send the first PDCCH and / or the second PDCCH indicated by the LP-WUS.

[0334] Optionally, the network device sends an LP-WUS that does not indicate wake-up, and keeps the sending status of the first PDCCH and / or the second PDCCH unchanged.

[0335] In some embodiments, the network device further implements:

[0336] Based on the LP-WUS indicating wake-up, the network device resumes sending the first PDCCH and / or the second PDCCH indicated by the LP-WUS.

[0337] Based on the different PDCCHs indicated by LP-WUS, the network device's reply wake-up is divided into the following situations:

[0338] Recovery situation 1: if the LP-WUS indicates the first PDCCH, based on the LP-WUS indicating wake-up, the network device resumes sending the first PDCCH;

[0339] Recovery situation 1: if the LP-WUS indicates the second PDCCH, based on the LP-WUS indicating wake-up, the network device resumes sending the second PDCCH;

[0340] Recovery situation three: if the LP-WUS indicates the first PDCCH and the second PDCCH, based on the LP-WUS indicating wake-up, the network device resumes sending the first PDCCH and the second PDCCH.

[0341] For the first recovery scenario, the LP-WUS indicates the first PDCCH, and the network device resumes sending the first PDCCH based on the LP-WUS.

[0342] After the network device resumes sending the first PDCCH, it can send the first PDCCH.

[0343] The network device being able to send the first PDCCH can be understood as the network device being able to send the first PDCCH based on a certain mechanism (such as a DRX mechanism), but does not mean that the first PDCCH is always sent.

[0344] Optionally, the network device sends the first PDCCH during an activation period of unicast DRX.

[0345] In some embodiments, the transmission status of the second PDCCH remains unchanged.

[0346] If the network device sends an LP-WUS to indicate the first PDCCH, it can be understood that the LP-WUS does not indicate the second PDCCH, the LP-WUS does not control the second PDCCH, and the network device keeps the sending status of the second PDCCH unchanged.

[0347] In one example, before the network device sends the LP-WUS, the transmission state of the second PDCCH is sending. After sending the LP-WUS, the network device resumes sending the first PDCCH and maintains sending the second PDCCH.

[0348] In one example, before the network device sends the LP-WUS, the transmission status of the second PDCCH is non-transmission. After sending the LP-WUS, the network device resumes transmission of the first PDCCH and keeps the second PDCCH non-transmission.

[0349] For the second recovery scenario, the LP-WUS indicates the second PDCCH, and the network device resumes sending the second PDCCH based on the LP-WUS.

[0350] After the network device resumes sending the second PDCCH, it can send the second PDCCH.

[0351] The network device being able to send the second PDCCH can be understood as the network device being able to send the second PDCCH based on a certain mechanism (eg, a DRX mechanism), but does not mean that the second PDCCH is always sent.

[0352] Optionally, the network device sends the second PDCCH during an activation period of multicast or broadcast DRX.

[0353] In some embodiments, the transmission status of the first PDCCH remains unchanged.

[0354] If the LP-WUS sent by the network device indicates the second PDCCH, it can be understood that the LP-WUS does not indicate the first PDCCH, the LP-WUS does not control the first PDCCH, and the network device keeps the transmission status of the first PDCCH unchanged.

[0355] In one example, before the network device sends the LP-WUS, the transmission state of the first PDCCH is sending. After sending the LP-WUS, the network device resumes sending the second PDCCH and maintains sending the first PDCCH.

[0356] In one example, before the network device sends the LP-WUS, the transmission status of the first PDCCH is non-transmission. After sending the LP-WUS, the network device resumes transmission of the second PDCCH and keeps the first PDCCH non-transmission.

[0357] For recovery situation three, the LP-WUS indicates the first PDCCH and the second PDCCH, and the network device resumes sending the first PDCCH and the second PDCCH based on the LP-WUS.

[0358] After the network device resumes sending the first PDCCH and the second PDCCH, it can send the first PDCCH and the second PDCCH.

[0359] The network device being able to send the first PDCCH and the second PDCCH can be understood as the network device being able to send the first PDCCH and the second PDCCH based on a certain mechanism (eg, a DRX mechanism), but does not mean that the first PDCCH and the second PDCCH are always sent.

[0360] Optionally, the network device sends the first PDCCH during an activation period of unicast DRX, and sends the second PDCCH during an activation period of multicast or broadcast DRX.

[0361] In some embodiments, the network device does not transmit the first PDCCH and / or the second PDCCH before resuming transmission of the first PDCCH and / or the second PDCCH.

[0362] The network device does not monitor the first PDCCH and / or the second PDCCH before sending the LP-WUS indicating the wake-up. When the network device sends the LP-WUS indicating the wake-up, the network device resumes sending the first PDCCH and / or the second PDCCH indicated by the LP-WUS based on the sent LP-WUS indicating the wake-up.

[0363] In the embodiment of the present application, the behavior of the MR of the terminal device in the sleep state includes the following situations:

[0364] Transmission case 1: neither the first PDCCH nor the second PDCCH is transmitted;

[0365] Transmission case 2: the first PDCCH is not transmitted, but the second PDCCH is transmitted;

[0366] Transmission case 3: the first PDCCH is transmitted, and the second PDCCH is not transmitted.

[0367] In some embodiments, if the LP-WUS indicates the second PDCCH, the LP-WUS indicates one or more of the following:

[0368] a PDCCH indicating multicast scheduling and / or a PDCCH indicating broadcast scheduling;

[0369] The RNTI scrambled PDCCH indicates multicast or broadcast scheduling.

[0370] In an embodiment of the present application, for different second PDCCHs, the division method may include: division based on multicast and broadcast and / or division based on different RNTIs. When the division method includes division based on multicast and broadcast, the LP-WUS separately indicates the PDCCH indicating multicast scheduling and the PDCCH indicating broadcast. When the division method includes division based on RNTI, the LP-WUS separately indicates the PDCCH indicating multicast scheduling and / or broadcast scheduling that are scrambled by different RNTIs.

[0371] In one example, the second PDCCH indicated by the LP-WUS includes: a PDCCH indicating multicast scheduling and / or a PDCCH indicating broadcast scheduling, and the network device resumes sending the PDCCH indicating multicast scheduling and / or the PDCCH indicating broadcast scheduling.

[0372] In an example, the second PDCCH indicated by the LP-WUS includes one or more RNTI1-scrambled PDCCHs indicating multicast or broadcast scheduling, and the network device resumes sending one or more RNTI1-scrambled PDCCHs indicating multicast or broadcast scheduling.

[0373] In one example, the second PDCCH indicated by the LP-WUS includes: a PDCCH indicating multicast scheduling and one or more RNTI-scrambled PDCCHs indicating multicast scheduling, and the network device resumes sending the PDCCH indicating multicast scheduling and one or more RNTI-scrambled PDCCHs indicating multicast scheduling.

[0374] In one example, the second PDCCH indicated by the LP-WUS includes: a PDCCH indicating broadcast scheduling and one or more RNTI-scrambled PDCCHs indicating multicast scheduling, then the network device resumes sending the PDCCH indicating broadcast scheduling and one or more RNTI-scrambled PDCCHs indicating multicast scheduling.

[0375] In an embodiment of the present application, when one or more LP-WUSs monitor or transmit a PDCCH indicating unicast scheduling and a PDCCH indicating multicast and / or broadcast scheduling, different PDCCHs can be controlled by the same LP-WUS, or each PDCCH can be controlled separately by a different LP-WUS, thereby improving the control flexibility of PDCCH monitoring or transmission.

[0376] In some embodiments, if the LP-WUS is used to control the transmission of the first PDCCH and the second PDCCH, or the LP-WUS is used to control the transmission of the first PDCCH and / or the second PDCCH indicated by the LP-WUS, the network device further performs:

[0377] The network device configures first configuration information for the terminal device, where the first configuration information is used for monitoring of the LP-WUS.

[0378] In transmission control mode 1 or transmission control mode 2, the transmission of the first PDCCH and the second PDCCH uses the same LP-WUS control, the network device configures first configuration information to the terminal device, the first configuration information is used for monitoring LP-WUS, and the terminal device monitors LP-WUS based on the first configuration information.

[0379] Optionally, the first configuration information may include: LP-WUS monitoring resource configuration.

[0380] In some embodiments, the LP-WUS is used to control the transmission of a target PDCCH corresponding to the LP-WUS, and the target PDCCH is the first PDCCH or the second PDCCH.

[0381] Here, the transmission control mode of the LP-WUS for the first PDCCH and the second PDCCH is transmission control mode three: different LP-WUSs are used for transmission of the corresponding first PDCCH or second PDCCH.

[0382] In the third transmission control mode, the PDCCH corresponding to the LP-WUS sent by the network device is called the target PDCCH, wherein the target PDCCH is or belongs to the first PDCCH or the second PDCCH.

[0383] In one example, the LP-WUS corresponds to the first PDCCH, and the LP-WUS is used to control the transmission of the first PDCCH. At this time, the transmission scenario is transmission scenario one.

[0384] In one example, the LP-WUS corresponds to the second PDCCH, and the LP-WUS is used to control monitoring of the second PDCCH. In this case, the transmission scenario is the second transmission scenario.

[0385] The first PDCCH and the second PDCCH correspond to different LP-WUSs, respectively. It is understandable that the transmission of the first PDCCH and the second PDCCH is controlled by using the LP-WUS corresponding to each PDCCH, respectively. Each LP-WUS is used to control the transmission of the corresponding PDCCH.

[0386] In an embodiment of the present application, the network device may determine the target PDCCH corresponding to the sent LP-WUS based on the resource or LP-WUS sequence of the sent LP-WUS, and may also carry indication information indicating the target PDCCH in the sent LP-WUS, such as: the RNTI of the scrambled target PDCCH, the channel identifier for identifying the target PDCCH, etc.

[0387] For the transmission control mode 3, the LP-WUS sent by the network device is used to control a PDCCH.

[0388] In some embodiments, the LP-WUS is one of a plurality of LP-WUSs, the plurality of LP-WUSs comprising:

[0389] a first LP-WUS, where the first LP-WUS is used to control transmission of the first PDCCH;

[0390] One or more second LP-WUSs, where the second LP-WUSs are used to control the transmission of the second PDCCH.

[0391] In some embodiments, a different second LP-WUS among the plurality of second LP-WUSs is used to:

[0392] controlling the transmission of a PDCCH indicating multicast scheduling or a PDCCH indicating broadcast scheduling; or,

[0393] Controls the transmission of PDCCHs scrambled by different RNTIs and indicating multicast or broadcast scheduling.

[0394] In an embodiment of the present application, for different second PDCCHs, the division method may include: division based on multicast and broadcast and / or division based on different RNTIs. When the division method includes division based on multicast and broadcast, the LP-WUS separately indicates the PDCCH indicating multicast scheduling and the PDCCH indicating broadcast. When the division method includes division based on RNTI, the LP-WUS separately indicates the PDCCH indicating multicast scheduling and / or broadcast scheduling that are scrambled by different RNTIs.

[0395] The second LP-WUS may be an LP-WUS corresponding to a second PDCCH divided based on multicast or broadcast, and the second LP-WUS is used to control the transmission of a PDCCH indicating multicast scheduling or a PDCCH indicating broadcast scheduling.

[0396] In an example, the second LP-WUS sent by the network device is used to control the sending of the PDCCH indicating multicast scheduling, and the network device controls the sending of the PDCCH indicating multicast scheduling based on the second LP-WUS.

[0397] In an example, the second LP-WUS sent by the network device is used to control the sending of the PDCCH indicating broadcast scheduling, and the network device controls the sending of the PDCCH indicating broadcast scheduling based on the second LP-WUS.

[0398] The second LP-WUS may be an LP-WUS corresponding to a second PDCCH divided based on the RNTI, and the second LP-WUS is used to control the transmission of the RNTI-scrambled PDCCH indicating multicast or broadcast scheduling.

[0399] In one example, the second LP-WUS sent by the network device is used to control the transmission of the PDCCH indicating multicast / broadcast scheduling scrambled by the first RNTI, and the network device controls the transmission of the PDCCH indicating multicast / broadcast scheduling scrambled by the first RNTI based on the second LP-WUS.

[0400] In one example, the second LP-WUS sent by the network device is used to control the transmission of the PDCCH indicating multicast / broadcast scheduling that is scrambled by the second RNTI, and the network device controls the transmission of the PDCCH indicating multicast / broadcast scheduling that is scrambled by the second RNTI based on the second LP-WUS.

[0401] In some embodiments, the LP-WUS indicated to wake up is used to resume sending a target PDCCH corresponding to the LP-WUS.

[0402] In an embodiment of the present application, the LP-WUS may or may not indicate wake-up. For the LP-WUS that indicates wake-up, it is also used to indicate the first PDCCH or the second PDCCH, and the LP-WUS is used to wake up the MR to send the first PDCCH or the second PDCCH corresponding to the LP-WUS.

[0403] In some embodiments, the network device further implements:

[0404] Based on the LP-WUS indicating wake-up, the network device resumes transmission of the target PDCCH.

[0405] Based on the different PDCCHs corresponding to LP-WUS, network device recovery is divided into the following situations:

[0406] Recovery situation four: if the LP-WUS is the first LP-WUS corresponding to the first PDCCH, based on the first LP-WUS indicating wake-up, the network device resumes sending the first PDCCH;

[0407] Recovery situation five: if the LP-WUS is the second LP-WUS corresponding to the second PDCCH, based on the second LP-WUS indicating wake-up, the network device resumes sending the second PDCCH.

[0408] For recovery situation four, the LP-WUS sent by the network device is the first LP-WUS corresponding to the first PDCCH, and the network device resumes sending the first PDCCH based on the LP-WUS.

[0409] After the network device resumes sending the first PDCCH, it can send the first PDCCH.

[0410] In some embodiments, the transmission status of the second PDCCH remains unchanged.

[0411] For recovery situation five, the network sets the LP-WUS sent to be the second LP-WUS corresponding to the second PDCCH, and the network device resumes sending the second PDCCH based on the LP-WSU.

[0412] After the network device resumes sending the second PDCCH, it can send the second PDCCH.

[0413] In some embodiments, the transmission status of the first PDCCH remains unchanged.

[0414] Optionally, if the second PDCCH corresponding to the second LP-WUS is a PDCCH indicating multicast scheduling, the sending status of the PDCCH indicating broadcast scheduling remains unchanged.

[0415] When the second LP-WUS sent by the network device corresponds to the PDCCH indicating multicast scheduling, the network device resumes sending the PDCCH indicating multicast scheduling and keeps the sending state of the PDCCH indicating broadcast scheduling unchanged.

[0416] Optionally, if the second PDCCH corresponding to the second LP-WUS is a PDCCH indicating broadcast scheduling, the sending status of the PDCCH indicating multicast scheduling remains unchanged.

[0417] When the second LP-WUS sent by the network device corresponds to the PDCCH indicating broadcast scheduling, the network device resumes sending the PDCCH indicating broadcast scheduling and keeps the sending state of the PDCCH indicating multicast scheduling unchanged.

[0418] Optionally, if the second PDCCH corresponding to the second LP-WUS is a PDCCH scrambled by the first RNTI and indicating multicast or broadcast scheduling, the transmission status of the PDCCH scrambled by the second RNTI and indicating multicast or broadcast scheduling remains unchanged.

[0419] When the second LP-WUS sent by the network device is the LP-WUS corresponding to the second PDCCH divided based on RNTI, and the second LP-WUS currently sent corresponds to the PDCCH indicating multicast or broadcast scheduling encrypted by the first RNTI, the sending of the PDCCH indicating multicast or broadcast scheduling encrypted by the first RNTI is resumed, and the sending status of the PDCCH indicating multicast or broadcast scheduling encrypted by the second RNTI is maintained.

[0420] In some embodiments, the network device does not transmit the first PDCCH and / or the second PDCCH before resuming transmission of the target PDCCH.

[0421] In some embodiments, if the LP-WUS is used to control the transmission of a target PDCCH corresponding to the LP-WUS, the network device further performs:

[0422] The network device configures a plurality of second configuration information to the terminal device, where the plurality of second configuration information is used for monitoring of the plurality of LP-WUSs.

[0423] In transmission control mode three, the transmission of the first PDCCH and the second PDCCH is controlled by different LP-WUSs, and different second PDCCHs are controlled by different LP-WUSs. The network device configures multiple second configuration information to the terminal device, and different second configuration information is used to transmit LP-WUS corresponding to different PDCCHs. The terminal device then monitors the LP-WUS corresponding to each PDCCH based on the multiple second configuration information. The different PDCCHs here can be understood as the first PDCCH and the second PDCCH, or different second PDCCHs.

[0424] Optionally, the second configuration information may include one or more of the following: LP-WUS monitoring resource configuration, LP-WUS sequence (LP-WUS code). The second configuration may also be used for the terminal device to identify different LP-WUSs.

[0425] In some embodiments, the LP-WUS is used to control the execution of the transmission of the first PDCCH and / or the second PDCCH of the terminal device after a first time offset of a second time, where the second time is the time of transmitting the LP-WUS.

[0426] After a first time offset after receiving the LP-WUS, the network device controls transmission of the first PDCCH and / or the second PDCCH based on the transmitted LP-WUS.

[0445] - The UE does not monitor the PDCCH indicating multicast and / or broadcast scheduling (such as the PDCCH scrambled by G-RNTI or G-CS-RNTI).

[0446] 3. After the UE receives the LP-WUS from the network, the UE's low power receiver (LR) sends a wake-up indication to the MR, and the MR simultaneously resumes monitoring of the PDCCH indicating unicast scheduling and the PDCCH indicating multicast and / or broadcast scheduling. The specific manner of resuming PDCCH monitoring may be, but is not limited to, one or more of the following:

[0447] For unicast DRX:

[0448] - Mode 1: The UE starts the drx-onDurationTimer corresponding to DRX;

[0449] - Mode 2: For DRX, if the network device configures DCP for the UE, the UE monitors the DCP and decides whether to start the corresponding drx-onDurationTimer based on the reception of the DCP;

[0450] - Mode 3: The UE starts a first timer corresponding to DRX. During the running of the first timer, DRX is in DRX Active Time. The first timer may be drx-InactivityTimer or another timer.

[0451] -Method 4: Directly enter DRX Active Time.

[0452] For multicast and / or broadcast DRX:

[0453] Method 1: The UE starts the drx-onDurationTimerPTM corresponding to each multicast DRX and / or the drx-onDurationTimerPTM corresponding to each broadcast DRX;

[0454] Mode 2: The UE starts a second timer corresponding to each multicast DRX and / or each broadcast DRX.

The second timer may be the drx-InactivityTimerPTM corresponding to the multicast or broadcast DRX or another timer.

[0468] Optionally, for the multicast and / or broadcast PDCCH monitoring status, the LP-WUS may indicate each multicast DRX and / or broadcast DRX (ie, the DRX corresponding to each G-RNTI or G-CS-CRNTI) separately.
