Description

Wireless communication method, terminal device and network device Technical Field

[0001] The embodiments of the present application relate to the field of communications, and specifically to a wireless communication method, terminal device, and network device. Background Art

[0002] In the discontinuous reception (DRX) mechanism, in order to reduce the power consumption of the terminal, a wake-up signal (WUS) is introduced. The terminal device blindly detects the PDCCH-based power saving signaling (PDCCH-WUS) based on the physical downlink control channel (PDCCH) based on a fixed offset. If the PDCCH-WUS is detected and the WUS indicates that the terminal device is to wake up, the terminal device starts the DRX duration timer (drx-ondurationTimer); in other cases, the terminal device does not start the drx-ondurationTimer.

[0003] Energy-saving technologies for connected devices (including the DRX and WUS mechanisms) are designed to ensure that the terminal device's primary receiver is always on. To further save energy for connected devices, the introduction of an ultra-low power wake-up signal (LP-WUS)—that is, the use of a receiver with lower power consumption—is being considered. Because the state of a terminal device's primary receiver affects the scheduling of network devices, determining the state of the terminal device's primary receiver when it receives the LP-WUS and ensuring that the terminal device and network devices have a consistent understanding of the state of the terminal device's primary receiver is an urgent issue.

[0004] Summary of the Invention

[0005] The present application provides a wireless communication method, terminal device, and network device, which are conducive to ensuring that the terminal device and the network device have a consistent understanding of the status of the terminal device's main receiver.

[0007] In a second aspect, a method for wireless communication is provided, including: a network device receives first information sent by a terminal device, the first information being related to a state of a main receiver of the terminal device when the terminal device enters a low power consumption state; and determining, based on the first information, the state of the main receiver of the terminal device when the terminal device enters a low power consumption state.

[0008] In a third aspect, a terminal device is provided for executing the method in the above-mentioned first aspect or its various implementations.

[0009] Specifically, the terminal device includes a functional module for executing the method in the above-mentioned first aspect or its various implementation modes.

[0010] In a fourth aspect, a network device is provided for executing the method in the above second aspect or its various implementations.

[0011] Specifically, the network device includes a functional module for executing the method in the above-mentioned second aspect or its various implementation modes.

[0012] In a fifth aspect, a terminal device is provided, comprising a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to call and execute the computer program stored in the memory to perform the method of the first aspect or its respective implementations.

[0013] In a sixth aspect, a network device is provided, comprising a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to call and execute the computer program stored in the memory to perform the method of the second aspect or its respective implementations.

[0014] In a seventh aspect, a chip is provided for implementing the method in any one of the first to second aspects or their respective implementations.

[0015] Specifically, the chip includes: a processor for calling and running a computer program from a memory, so that a device equipped with the device executes the method in any one of the first to second aspects or their respective implementations.

[0016] In an eighth aspect, a computer-readable storage medium is provided for storing a computer program, which enables a computer to execute the method of any one of the first to second aspects or their respective implementations.

[0017] In a ninth aspect, a computer program product is provided, comprising computer program instructions, wherein the computer program instructions enable a computer to execute the method of any one of the first to second aspects or their respective implementations.

[0018] In a tenth aspect, a computer program is provided, which, when executed on a computer, enables the computer to execute the method of any one of the first to second aspects or their respective implementations.

[0019] Through the above technical solution, the terminal device can report to the network device information related to the state of the terminal device's main receiver when the terminal device enters a low-power state. Furthermore, the network device can determine the state of the terminal device's main receiver based on the information reported by the network device, which is conducive to ensuring that the terminal device and the network device have a consistent understanding of the state of the main receiver. Because different states correspond to different wake-up delays, the network device can schedule downlink transmission after the wake-up delay corresponding to the state of the main receiver, which can avoid scheduling downlink transmission during the wake-up period of the main receiver, resulting in the terminal device being unable to perform downlink reception and other resource waste.

Wearable devices may also be called wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0041] In an embodiment of the present application, the network device may be a device for communicating with a mobile device. The network device may be an access point (AP) in WLAN, a base station (BTS) in GSM or CDMA, a base station (NodeB, NB) in WCDMA, an evolved base station (eNB or eNodeB) in LTE, or a relay station or access point, or a vehicle-mounted device, a wearable device, and a network device (gNB) in an NR network, or a network device in a future evolved PLMN network or a network device in an NTN network, etc.

The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0044] For example, a communication system 100 used in an embodiment of the present application is shown in FIG1 . The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal or terminal). The network device 110 may provide communication coverage for a specific geographic area and may communicate with terminal devices within the coverage area.

[0045] FIG1 exemplarily shows a network device and two terminal devices. Optionally, the communication system 100 may include multiple network devices and each network device may include another number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0046] Optionally, the communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

[0047] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system 100 shown in FIG1 as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function. The network device 110 and the terminal device 120 may be the specific devices described above and will not be described in detail here. The communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in the embodiments of the present application.

[0048] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0049] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0050] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0051] In the embodiments of the present application, "pre-defined" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal device or a network device). The present application does not limit the specific implementation method. For example, pre-defined may refer to information defined in a protocol.

[0052] In the embodiments of the present application, the "protocol" may refer to a standard protocol in the communication field, for example, it may include an LTE protocol, an NR protocol, and related protocols used in future communication systems, and this application does not limit this.

[0053] The indication information in the embodiment of the present application is configured through at least one of the following signaling: system message, physical layer signaling (such as downlink control information (DCI)), radio resource control (RRC) signaling and media access control element (MAC CE).

[0054] With the increasing demand for speed, latency, high-speed mobility, and energy efficiency, coupled with the increasing diversity and complexity of future services, the 3GPP international standards organization has begun developing 5G. Key 5G application scenarios include enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (URLLC), and massive machine-type communication (mMTC).

[0055] It should be understood that in the embodiment of the present application, NR can also be deployed independently. In order to reduce air interface signaling and quickly restore wireless connections and quickly restore data services in the 5G network environment, a new radio resource control (RRC) state is defined, namely the RRC_INACTIVE state. This state is different from the RRC_IDLE and RRC_CONNECTED states.

[0056] In the RRC_IDLE state, mobility is based on cell selection and reselection by the terminal device, paging is initiated by the core network (CN), and the paging area is configured by the CN. There is no terminal device access stratum (AS) context on the base station side, and no RRC connection exists.

[0057] In the RRC_CONNECTED state, an RRC connection exists, and a device AS context exists between the base station and the terminal. The network knows the terminal's location at the cell level. Mobility is controlled by the network. Unicast data can be transmitted between the terminal and the base station.

[0058] RRC_INACTIVE: Mobility is based on cell selection and reselection of the terminal device. There is a connection between CN and NR. The AS context of the terminal device exists on a certain base station. Paging is triggered by the Radio Access Network (RAN). The RAN-based paging area is managed by the RAN. The network equipment knows the location of the terminal device based on the RAN paging area level.

[0059] It should be noted that in the embodiments of the present application, the non-activated state may also be referred to as the deactivated state, and the present application does not limit this.

[0060] In some scenarios, in order to save power for the terminal, the concept of discontinuous reception (DRX) is proposed. Specifically, the network device can configure the terminal device to wake up (DRX ON) at a time predicted by the network and monitor the physical downlink control channel (PDCCH). At the same time, the network can also configure the terminal device to sleep (DRX OFF) at a time predicted by the network, that is, the terminal device does not need to monitor the PDCCH. Therefore, if the network device has data to transmit to the terminal device, the network device can schedule the terminal device during the time when the terminal device is in DRX ON, and during the DRC OFF time, the terminal power consumption can be reduced because the radio frequency is turned off.

[0061] In some embodiments, the network device can configure the DRX function for the terminal device so that the terminal device monitors the PDCCH discontinuously to achieve power saving. For example, each MAC entity can correspond to a DRX configuration. Optionally, the DRX configuration can include at least one of the following:

[0062] DRX onDuration Timer (drx-onDurationTimer): The duration of the terminal device waking up at the beginning of a DRX cycle.

[0063] DRX slot offset (drx-SlotOffset): The delay for the terminal device to start the drx-onDurationTimer.

[0064] DRX inactivity timer (drx-InactivityTimer): When the terminal device receives a PDCCH indicating an uplink initial transmission or a downlink initial transmission, the terminal device continues to monitor the PDCCH for a certain period of time.

[0065] DRX downlink retransmission timer (drx-RetransmissionTimerDL): The maximum duration that a terminal device monitors the PDCCH indicating downlink retransmission scheduling. Each downlink HARQ process, except the broadcast HARQ process, corresponds to one drx-RetransmissionTimerDL.

[0066] DRX Uplink Retransmission Timer (drx-RetransmissionTimerUL): The maximum duration that a terminal device monitors the PDCCH indicating uplink retransmission scheduling. Each uplink HARQ process corresponds to one drx-RetransmissionTimerUL.

[0067] Long DRX cycle start offset (longDRX-CycleStartOffset): used to configure the long DRX cycle, as well as the subframe offsets at which the long DRX cycle and the short DRX cycle start.

[0068] Short DRX cycle (drx-ShortCycle): Short DRX cycle, which is an optional configuration.

[0069] Short cycle timer (drx-ShortCycleTimer): The duration that the terminal device is in a short DRX cycle (and does not receive any PDCCH), which is an optional configuration.

[0070] Downlink Hybrid Automatic Repeat Request (HARQ) Round Trip Time (RTT) Timer (drx-HARQ-RTT-TimerDL): The minimum waiting time a terminal device must wait before receiving a PDCCH indicating downlink scheduling. Each downlink HARQ process, except the broadcast HARQ process, corresponds to one HARQ RTT Timer.

[0071] Uplink HARQ RTT Timer (drx-HARQ-RTT-TimerUL): The minimum waiting time required for a terminal device to receive a PDCCH indicating uplink scheduling. Each uplink HARQ process corresponds to one drx-HARQ-RTT-TimerUL.

[0072] If the terminal device is configured with DRX, the terminal device needs to monitor the PDCCH during the DRX active time. The DRX active time includes the following situations:

[0073] Any of the drx-onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimerDL, drx-RetransmissionTimerUL, and random access contention resolution timer (ra-ContentionResolutionTimer) is running;

[0074] The terminal device sends a Scheduling Request (SR) on the PUCCH and is in a pending state;

[0075] In a contention-based random access process, after successfully receiving a random access response, the terminal device has not yet received an initial transmission indicated by a PDCCH scrambled by a cell radio network temporary identifier (Cell RNTI, C-RNTI).

[0076] In some embodiments, the terminal device may determine the time to start the drx-onDurationTimer according to whether it is currently in a long DRX cycle or a short DRX cycle. For example, the specific provisions are as follows:

[0077] If a short DRX cycle is used, and the current subframe satisfies [(SFN×10)+subframe number] modulo(drx-ShortCycle)=(drx-StartOffset) modulo(drx-ShortCycle).

[0078] If a long DRX cycle is used, and the current subframe satisfies [(SFN×10)+subframe number] modulo(drx-LongCycle)=drx-StartOffset.

[0079] Here, modulo represents the modulo operation.

[0080] In some embodiments, the terminal device may start drx-onDurationTimer at a time drx-SlotOffset slots after the start of the current subframe.

[0081] In some embodiments, the conditions for starting or restarting the drx-InactivityTimer include but are not limited to:

[0082] If the terminal device receives a PDCCH indicating a downlink or uplink initial transmission, the terminal device starts or restarts the drx-InactivityTimer.

[0083] In some embodiments, the conditions for starting and stopping drx-RetransmissionTimerDL include but are not limited to:

[0084] When the terminal device receives a PDCCH indicating a downlink transmission, or when the terminal device receives a MAC PDU on the configured downlink grant resource, the terminal device stops the drx-RetransmissionTimerDL corresponding to the HARQ process;

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

[0086] In some embodiments, the conditions for the terminal device to start and stop drx-RetransmissionTimerUL include but are not limited to:

[0087] When the terminal device receives a PDCCH indicating an uplink transmission, or when the terminal device sends a MAC PDU on the configured uplink grant resource, the terminal device stops the drx-RetransmissionTimerUL corresponding to the HARQ process. The terminal device starts the drx-HARQ-RTT-TimerUL corresponding to the HARQ process after completing the first repetition of the PUSCH;

[0088] If the drx-HARQ-RTT-TimerUL corresponding to a certain HARQ of the terminal device times out, the terminal device starts the drx-RetransmissionTimerUL corresponding to this HARQ process.

[0089] In some embodiments, the terminal device uses the long DRX cycle by default, and the short DRX cycle is an optional configuration. For a terminal device configured with the short DRX cycle, it can switch between the short DRX cycle and the long DRX cycle based on a certain method.

[0090] For example, if the drx-InactivityTimer times out and / or the terminal device receives a DRX command media access control control element (DRX Command MAC CE), the terminal device uses a long DRX cycle.

[0091] For another example, if the drx-ShortCycleTimer times out and / or the terminal device receives a long DRX command MAC CE, the terminal device uses a short DRX cycle.

[0092] In the NR system, in order to reduce the power consumption of the terminal, power saving signaling is introduced. The terminal device blindly detects the PDCCH-based power saving signaling (PDCCH-WUS) based on a fixed offset. If PDCCH-WUS is detected and the WUS indicates that the terminal device is to wake up, the terminal device starts the drx-ondurationTimer; in other cases, the terminal device does not start the drx-ondurationTimer.

[0093] For connected terminal devices, the above energy-saving technologies (including the DRX mechanism and the WUS mechanism) are designed for the terminal's main receiver to be always on. To further save energy for connected terminal devices, the introduction of a low-power wake-up signal (ultra-low power WUS, LP-WUS) is considered. Figure 2 is a schematic diagram based on the working principle of LP-WUS, in which the terminal device includes a main receiver (or main radio) and an LP-WUS receiver. The power consumption of the LP-WUS receiver is lower than that of the main receiver. Before the terminal device receives the LP-WUS (i.e., enters the low-power receiving state), the main receiver is turned off or in a sleep state. Only after receiving the LP-WUS does the terminal device start the main receiver to monitor the downlink signal to achieve the purpose of energy saving.

[0094] After the terminal device enters the low-power receiving state, the terminal device's main receiver may still have different sleep states, such as deep sleep state, light sleep state, micro sleep state, and off state. For different sleep states, the wake-up time of the main receiver is different. Therefore, different sleep states have an impact on the scheduling of network devices. Therefore, how to ensure that the terminal device and the network device have a consistent understanding of the main receiver state is an urgent problem that needs to be solved.

[0095] 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.

[0096] FIG3 is a schematic interaction diagram of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG3 , the method 200 includes the following contents:

[0097] S210, the terminal device sends first information to the network device, where the first information is related to the state of the main receiver of the terminal device when the terminal device enters a low power consumption state.

[0098] In some embodiments, the terminal device is in an RRC connected (RRC_CONNECTED) state.

[0099] In some embodiments, the terminal device includes a main receiver and a low power consumption receiver (or LP-WUS receiver), wherein the power consumption of the low power consumption receiver is lower than the power consumption of the main receiver.

[0100] In some embodiments, the terminal device entering a low power consumption state (or a low power consumption receiving state) may refer to:

[0101] The low-power receiver of the terminal device is in a receiving state (or in an on-state or working state), and / or

[0102] The main receiver of the terminal device exits the working state (or exits the receiving state).

[0103] In some embodiments, the state of the primary receiver of the terminal device may refer to the mode of the primary receiver, or the state of the primary receiver corresponds to the mode of the primary receiver. That is, the state of the primary receiver and the mode of the primary receiver can be interchangeable, or the state of the primary receiver and the mode of the primary receiver have a corresponding relationship.

[0104] In some embodiments, the state of the primary receiver may refer to a reception state of the primary receiver, a sleep state of the primary receiver, a mode of the primary receiver, or a sleep mode of the primary receiver. The state of the primary receiver is used to indicate the degree to which the primary receiver is sleepy, has exited an operating state, or is capable of downlink reception.

[0105] In some embodiments, different states of the primary receiver may correspond to different wake-up delays, or power consumption, etc., wherein the wake-up delay corresponding to a state may be the delay required for the primary receiver to be awakened from the state and ready to receive downlink signals. Optionally, the downlink signal may include, but is not limited to, at least one of the following: PDCCH, Physical Downlink Shared Channel (PDSCH), Master Information Block (MIB), paging message (paging), Synchronization Signal Block (SSB), Channel State Information Reference Signal (CSI-RS).

[0106] In some embodiments, the time period from when the terminal device's main receiver is awakened to when it is ready to receive downlink signals is called the wake-up period. When the main receiver is in the wake-up period, downlink reception cannot be performed. Therefore, if the network device performs downlink scheduling during the wake-up period, it will result in a waste of resources.

[0107] In some embodiments, the state of the main receiver of the terminal device can be multiple, and this application does not limit the number of states of the main receiver. As an example, the state of the main receiver of the terminal device can include but is not limited to at least one of the following:

[0108] The first state, the second state, the third state, the fourth state, wherein,

[0109] The power consumption of the main receiver when it is in the first state, the second state, the third state and the fourth state decreases in sequence, and / or,

[0110] The wake-up delay corresponding to the first state, the wake-up delay corresponding to the second state, the wake-up delay corresponding to the third state, and the wake-up delay corresponding to the fourth state increase in sequence.

[0111] In some embodiments, the first state is a micro sleep state, the second state is a light sleep state, the third state is a deep sleep state, and the fourth state is an off state.

[0112] Optionally, the micro sleep state may be a micro sleep mode, or the micro sleep state corresponds to the micro sleep mode.

[0113] Optionally, the light sleep state may be a light sleep mode, or the light sleep state corresponds to the light sleep mode.

[0114] Optionally, the deep sleep state may be a deep sleep mode, or the deep sleep state corresponds to the deep sleep mode.

[0115] Optionally, the off state may be an off mode, or the off state corresponds to the off mode.

[0116] It should be understood that the above-mentioned states of the main receiver are only examples. In other embodiments, more states or fewer states may be included, and this application does not limit this.

[0117] In some embodiments, the main receiver may have N states, which are the full set of the main receiver states. The N states may be predefined or divided according to certain rules. The network device and the terminal device have the same understanding of the N states. For a terminal device, it may support all N states or only some of the N states. For different terminal devices, the states they support may be the same or different.

[0118] In some embodiments, the first information is sent when the network device supports sending a WUS signal and / or the network device supports the terminal device reporting information related to the status of the main receiver.

[0119] For example, the first information is sent after receiving the third configuration information of the network device, wherein the third configuration information is used to indicate that the network device supports sending WUS signals and / or the network device supports the terminal device reporting information related to the status of the main receiver.

[0120] In some embodiments, the third configuration information is sent via at least one of the following signaling:

[0121] System messages, RRC signaling (such as RRC reconfiguration message), MAC CE, PDCCH.

[0122] Optionally, the system message may include a system information block (System Information Block, SIB), such as a master information block (Master Information Block, MIB), SIB1, SIB2 or other SIBs.

[0123] The following describes the specific implementation of wireless communication according to the embodiments of the present application in combination with specific embodiments.

[0124] Embodiment 1: The first information includes first capability information, and the first capability information includes capability information related to the status of the main receiver supported by the terminal device.

[0125] Optionally, the first capability information may be sent via uplink signaling, including but not limited to uplink radio resource control (RRC) signaling, uplink media access control element (MAC CE), and uplink control information (UCI).

[0126] In some embodiments, the first capability information may be carried in the terminal capability information (UECapabilityInformation) and reported to the network device. That is, the terminal device may report the status-related information of the supported primary receiver to the network device as a capability.

[0127] Optionally, the first capability information may explicitly indicate the status of the main receiver supported by the terminal device, or may implicitly indicate the status of the main receiver supported by the terminal device, for example, indicating other information related to the status of the main receiver supported by the terminal device, such as switching delay, etc.

[0128] In a specific embodiment, the first capability information includes at least one of the following:

[0129] one or more states of the primary receiver supported by the terminal device in the event that the terminal device enters a low power state;

[0130] When the terminal device enters a low power consumption state, the terminal device supports one or more wake-up delays, and the one or more wake-up delays correspond to one or more states of the main receiver supported by the terminal device.

[0131] In some embodiments, the states of the primary receiver supported by the terminal device include one or more, for example, including but not limited to at least one of the following states: a first state, a second state, a third state, and a fourth state. The specific implementation of the first state, the second state, the third state, and the fourth state is described in the previous embodiment and will not be repeated here for the sake of brevity.

[0132] In some embodiments of the present application, the method 200 further includes:

[0133] The terminal device receives a first signaling sent by a network device, where the first signaling is used to configure a target state of a main receiver of the terminal device and / or a wake-up delay corresponding to the target state.

[0134] Optionally, the target state or the wake-up delay corresponding to the target state may be determined according to the first capability information.

[0135] For example, when the terminal device supports the first state, the first signaling can configure the state of the main receiver to be the first state.

[0136] For another example, when the terminal device supports the first state and the second state, the first signaling can configure the state of the main receiver to be the first state or the second state.

[0137] In some embodiments, the first signaling includes at least one of the following:

[0138] RRC signaling (e.g. RRC reconfiguration message), MAC CE, PDCCH.

[0139] In some embodiments, the first signaling is also used to instruct the terminal device to enter a low power consumption state.

[0140] That is, when the network device instructs the terminal device to enter a low power consumption state, it also instructs the terminal device to enter a low power consumption state, and the state of the main receiver of the terminal device.

[0141] It should be understood that the network device can instruct the terminal device to enter a low power consumption state and the state of the terminal device's main receiver when entering the low power consumption state through one signaling, or it can instruct the terminal device to enter a low power consumption state and the state of the terminal device's main receiver when entering the low power consumption state through two signalings.

[0142] In some embodiments, the method 200 further includes:

[0143] When the terminal device enters the low power consumption state, the main receiver of the terminal device enters the target state configured by the network device, or in other words, uses the target state configured by the network device.

[0144] The implementation process of Example 1 is described with reference to FIG4 . As shown in FIG4 , the following steps may be included:

[0145] S211, the terminal device reports first capability information to the network device.

[0146] Optionally, the first capability information may be sent when the network device supports sending a WUS signal and / or the network device supports the terminal device reporting information related to the status of a supported primary receiver.

[0147] S212, the network device sends a first signaling to the terminal device, where the first signaling is used to configure a target state of a main receiver of the terminal device and / or a wake-up delay corresponding to the target state.

[0148] Optionally, the target state may be determined based on the first capability information.

[0149] S213, after the terminal device enters the low power consumption state, the main receiver of the terminal device enters the target state configured by the network device.

[0150] Therefore, in this embodiment 1, the network device can configure the target state of the primary receiver for the terminal device based on the first capability information reported by the terminal device. Furthermore, when entering a low-power state, the terminal device's primary receiver enters the target state configured by the network device, thereby ensuring that the terminal device and the network device have a consistent understanding of the state of the primary receiver. Because different states correspond to different wake-up delays, the network device can schedule downlink transmissions after the wake-up delay corresponding to the state of the primary receiver, avoiding resource waste caused by scheduling downlink transmissions while the primary receiver is awake and the terminal device is unable to perform downlink reception.

[0151] Embodiment 2: The first information includes first indication information, and the first indication information is used to indicate information related to the state of the main receiver that the terminal device expects (or prefers, is interested in) when the terminal device enters a low power consumption state.

[0152] Optionally, the first indication information may explicitly indicate the state of the main receiver expected by the terminal device, or may implicitly indicate the state of the main receiver expected by the terminal device, for example, indicating other information related to the state of the main receiver expected by the terminal device, such as switching delay, etc.

[0153] In a specific embodiment, the first indication information is used to indicate at least one of the following:

[0154] one or more states of the primary receiver desired by the terminal device in the event that the terminal device enters a low power state;

[0155] When the terminal device enters a low power consumption state, the terminal device expects one or more wake-up delays, and the one or more wake-up delays correspond to one or more states of the main receiver expected by the terminal device.

[0156] In some embodiments, the state of the primary receiver desired by the terminal device may include at least one of the following:

[0157] The first state, the second state, the third state, and the fourth state are specifically implemented with reference to the relevant descriptions of the previous embodiment, and are not described here for brevity.

[0158] In some embodiments, the first indication information is sent via at least one of the following signaling:

[0159] RRC signaling, MAC CE, PUCCH. Optionally, the RRC signaling may include but is not limited to terminal assistance information (UEAssistanceInformation).

[0160] In some embodiments, the terminal device may determine the desired state of the primary receiver based on its own state and / or information about the service to be transmitted.

[0161] Optionally, the self-state may include but is not limited to the remaining battery capacity of the terminal device.

[0162] Optionally, the information of the service to be transmitted may include the type of the service to be transmitted and time domain requirements.

[0163] For example, when the remaining battery capacity of the terminal device is lower than a first threshold, the desired state of the main receiver is determined to be a state with lower power consumption, such as the third state or the fourth state.

[0164] For another example, when the latency requirement of the service to be transmitted is high, the desired state of the primary receiver is determined to be a state with a low wake-up latency, such as the first state or the second state.

[0165] In some embodiments, when the state of the primary receiver currently expected by the terminal device is different from the state of the expected primary receiver reported by the terminal device last (i.e., most recently), the terminal device sends the first indication information to the network device, where the first indication information is used to indicate the state of the primary receiver currently expected by the terminal device. That is, when the current state expected by the terminal device is different from the last expected state, the terminal device changes the state of the expected primary receiver by sending the first indication information, so that the network device configures the state of the expected primary receiver for the terminal device, while ensuring that the terminal device and the network device have the same understanding of the state of the primary receiver.

[0166] In some embodiments, when the state of the primary receiver currently expected by the terminal device is different from the state of the primary receiver configured by the network device for the terminal device (for example, the state of the primary receiver most recently configured by the network device for the terminal device), the terminal device sends the first indication information to the network device, where the first indication information is used to indicate the state of the primary receiver currently expected by the terminal device. That is, when the state currently expected by the terminal device is different from the state configured by the network device for the terminal device, the terminal device indicates the state of the primary receiver expected by the terminal device by sending the first indication information, so that the network device configures the state of the expected primary receiver for the terminal device, while ensuring that the terminal device and the network device have the same understanding of the state of the primary receiver.

[0167] In some embodiments, the first indication information is sent when the network device supports sending a WUS signal and / or the network device supports the terminal device reporting information related to the status of the desired primary receiver.

[0168] For example, the first indication information is sent after receiving the first configuration information of the network device, wherein the first configuration information is used to indicate that the network device supports sending WUS signals and / or the network device supports the terminal device reporting information related to the status of the expected main receiver.

[0169] In some embodiments, the first configuration information is sent via at least one of the following signaling:

[0170] System messages, RRC signaling (such as RRC reconfiguration message), MAC CE, PDCCH.

[0171] Optionally, the system message may include a SIB, such as MIB, SIB1, SIB2 or other SIBs.

[0172] In some embodiments, the method 200 further includes:

[0173] The terminal device receives second signaling sent by the network device, where the second signaling is used to configure or reconfigure a target state of a primary receiver of the terminal device and / or a wake-up delay corresponding to the target state. Optionally, the target state or the wake-up delay corresponding to the target state can be determined based on a desired state of the primary receiver of the terminal device.

[0174] For example, after the network device configures the target state of the primary receiver for the terminal device via first signaling, the terminal device sends first indication information to the network device, indicating the terminal device's current desired state of the primary receiver. If the terminal device's desired state of the primary receiver is different from the state of the primary receiver configured by the first signaling, the network device may send a second signaling to the terminal device based on the terminal device's desired state of the primary receiver, to reconfigure the target state of the terminal device's primary receiver.

[0175] For another example, the terminal device determines the desired state of the main receiver based on its own state or information about the service to be transmitted, and further sends a first indication message to the network device. The network device can then send a second signaling to the terminal device based on the desired state of the main receiver of the terminal device, to configure the target state of the main receiver of the terminal device.

[0176] The implementation process of Example 2 is described with reference to FIG5 . As shown in FIG5 , the following steps may be included:

[0177] S222: The terminal device determines the desired state of the primary receiver or the wake-up delay corresponding to the state.

[0178] For example, the terminal device determines the expected state of the main receiver or the wake-up delay corresponding to the state according to its own state or information about the service to be transmitted.

[0179] S223, the terminal device sends first indication information to the network device, which is used to indicate the state of the main receiver desired by the terminal device.

[0180] Optionally, the first indication information may be sent when the network device supports sending a WUS signal and / or the network device supports the terminal device reporting information related to the status of the desired main receiver.

[0181] For example, before S223, it also includes S222, the network device sends first configuration information to the terminal device, and the first configuration information is used to configure the network device to support sending WUS signals and / or the network device supports the terminal device to report information related to the status of the expected main receiver.

[0182] S234, the network device sends a second signaling to the terminal device, where the second signaling is used to configure or reconfigure the target state of the main receiver of the terminal device and / or the wake-up delay corresponding to the target state.

[0183] Optionally, the target state may be determined based on the state of the main receiver desired by the terminal device as indicated by the first indication information.

[0184] S225, after the terminal device enters the low power consumption state, the main receiver of the terminal device enters the target state of network device configuration or reconfiguration.

[0185] Therefore, in this embodiment 2, the network device can configure or reconfigure the target state of the primary receiver for the terminal device based on the first indication information sent by the terminal device. Furthermore, when entering the low-power state, the terminal device enters the target state configured or reconfigured by the network device, thereby ensuring that the terminal device and the network device have a consistent understanding of the state of the primary receiver. Because different states correspond to different wake-up delays, the network device can schedule downlink transmission after the wake-up delay corresponding to the state of the primary receiver, avoiding resource waste caused by scheduling downlink transmission during the awakening period of the primary receiver and the terminal device being unable to perform downlink reception.

[0186] Example 3: The first information includes second indication information, and the second indication information is used to indicate information related to the status of the main receiver that the terminal device determines to use (or decides to use, will use) or is currently using when the terminal device enters a low power consumption state.

[0187] Optionally, the second indication information may explicitly indicate the status of the main receiver determined to be used or currently used by the terminal device, or may implicitly indicate the status of the main receiver determined to be used or currently used by the terminal device, for example, indicating other information related to the status of the main receiver determined to be used or currently used by the terminal device, such as switching delay, etc.

[0188] In some embodiments, the second indication information is used to indicate at least one of the following:

[0189] In the event that the terminal device enters a low power consumption state, the terminal device determines a state of a primary receiver in use or currently in use;

[0190] One or more wake-up delays, the one or more wake-up delays corresponding to one or more states of the primary receiver determined to be used or currently used by the terminal device.

[0191] In some embodiments, the terminal device determines that the state of the primary receiver in use or currently in use is one of the following:

[0192] The first state, the second state, the third state, and the fourth state are specifically implemented with reference to the relevant descriptions of the previous embodiment, and are not described here for brevity.

[0193] In some embodiments, the second indication information is sent via at least one of the following signaling:

[0194] RRC signaling, MAC CE, PUCCH.

[0195] Optionally, the RRC signaling may include but is not limited to at least one of the following:

[0196] UE assistance information (UEAssistanceInformation) message, RRC connection establishment complete message, RRC reestablishment complete message, RRC recovery complete message, RRC reconfiguration complete message.

[0197] In some embodiments, the state of the primary receiver used or currently used by the terminal device may be determined by the terminal device according to its own state and / or information about the service to be transmitted.

[0198] Optionally, the self-state may include but is not limited to the remaining battery capacity of the terminal device.

[0199] Optionally, the information of the service to be transmitted may include the type of the service to be transmitted and time domain requirements.

[0200] For example, when the remaining battery capacity of the terminal device is lower than a first threshold, the state of the main receiver to be used is determined to be a state with lower power consumption, such as the third state or the fourth state.

[0201] For another example, when the latency requirement of the service to be transmitted is high, the state of the primary receiver to be used is determined to be a state with a low wake-up latency, such as the first state or the second state.

[0202] In some embodiments, the second indication information is sent when the network device supports sending a WUS signal and / or the network device supports the terminal device to report information related to the status of the main receiver determined to be in use or currently in use.

[0203] For example, the second indication information is sent after receiving the second configuration information of the network device, wherein the second configuration information is used to indicate that the network device supports sending WUS signals and / or that the network device supports the terminal device to report information related to the status of the main receiver determined to be used or currently used.

[0204] In some embodiments, when the state of the primary receiver determined to be used or currently used by the terminal device is different from the state of the primary receiver reported by the terminal device to the network device last time, the terminal device sends the second indication information to the network device.

[0205] In some embodiments, the second configuration information is sent via at least one of the following signaling: system message, RRC signaling, MAC CE, PDCCH.

[0206] Optionally, the system message may include a SIB, such as MIB, SIB1, SIB2 or other SIBs.

[0207] The implementation process of Example 3 is described in conjunction with Figure 6. As shown in Figure 6, the following steps may be included:

[0208] S232: The terminal device determines the state of the primary receiver to be used or the wake-up delay corresponding to the state.

[0209] For example, the terminal device determines the state of the primary receiver to be used or the wake-up delay corresponding to the state according to its own state and / or information about the service to be transmitted.

[0210] S233, the terminal device sends second indication information to the network device, which is used to instruct the terminal device to determine the status of the main receiver to be used.

[0211] Optionally, the second indication information may be sent when the network device supports sending a WUS signal and / or the network device supports the terminal device reporting information related to the status of the main receiver to be used.

[0212] For example, before S233, it also includes the following S231, the network device sends second configuration information to the terminal device, the second configuration information is used to configure the network device to support sending WUS signals and / or the network device supports the terminal device to report information related to the status of the main receiver determined to be used or currently used.

[0213] S234, after the terminal device enters the low power consumption state, the main receiver of the terminal device enters the state of the main receiver reported last time.

[0214] Therefore, in this embodiment 3, the terminal device can report the state of the primary receiver that is determined to be in use or currently in use to the network device. Furthermore, when entering a low-power state, the terminal device enters the reported state of the primary receiver, thereby ensuring that the terminal device and the network device have a consistent understanding of the state of the primary receiver. Because different states correspond to different wake-up delays, the network device can schedule downlink transmissions after the wake-up delay corresponding to the state of the primary receiver, avoiding resource waste caused by scheduling downlink transmissions during the awakening period of the primary receiver while the terminal device is unable to perform downlink reception.

[0215] It should be understood that in the embodiments of the present application, the above-mentioned embodiment 1, embodiment 2 and embodiment 3 can be implemented separately, or can be implemented in combination, and the present application does not limit this.

[0216] For example, the terminal device first reports first capability information to the network device, and the network device configures the state of the main receiver based on the first capability information. Further, the terminal device sends first indication information to the network device, indicating the state of the main receiver expected by the terminal device, and the network device sends second signaling to the terminal device based on the first indication information, which is used to reconfigure the state of the main receiver of the terminal device.

[0217] For another example, the terminal device first reports first capability information to the network device, and the network device configures the status of the main receiver based on the first capability information. Furthermore, the terminal device sends second indication information to the network device, instructing the terminal device to determine the status of the main receiver in use or currently in use.

[0218] For another example, the terminal device first reports first indication information to the network device, and the network device configures or reconfigures the status of the main receiver based on the first indication information. Further, the terminal device sends second indication information to the network device, instructing the terminal device to determine the status of the main receiver in use or currently in use.

[0219] Therefore, in an embodiment of the present application, the network device can configure the state of the main receiver for the terminal device. For example, the network device determines the state of the main receiver configured for the terminal device based on the first capability information or the first indication information, or the terminal device can report the state of the main receiver to the network device. Furthermore, when entering a low-power state, the terminal device enters the state of the main receiver configured or reported by the network device, thereby ensuring that the terminal device and the network device have a consistent understanding of the state of the main receiver. Since different states correspond to different wake-up delays, the network device can schedule downlink transmission after the wake-up delay corresponding to the state of the main receiver, thereby avoiding the waste of resources caused by scheduling downlink transmission during the wake-up period of the main receiver and the terminal device being unable to perform downlink reception.

The following text, in combination with Figures 7 to 11, describes in detail the device embodiment of the present application.
