[0045] Traditional communication systems typically support a limited number of connections and are easy to implement.

[0049] Please refer to Figure 1, which shows a schematic diagram of a network architecture 100 provided in one embodiment of this application. The network architecture 100 may include: a terminal device 10, an access network device 20, and a core network element 30.

[0050] Terminal device 10 can refer to UE (User Equipment), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, wireless communication device, user agent, or user equipment. In some embodiments, terminal device 10 can also be a cellular phone, cordless phone, SIP (Session Initiation Protocol) phone, WLL (Wireless Local Loop) station, PDA (Personal Digital Assistant), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal device in 5GS (5th Generation System), or terminal device in the future evolved PLMN (Public Land Mobile Network), etc., and this application embodiment is not limited to these. For ease of description, the devices mentioned above are collectively referred to as terminal devices. The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 can be distributed within the cell managed by each access network device 20. Terminal equipment can also be simply referred to as terminal or UE, the meaning of which can be understood by those skilled in the art.

[0051] Access network device 20 is a device deployed in an access network to provide wireless communication functionality to terminal device 10. Access network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the name of the device with access network device functionality may differ; for example, in a 5G NR system, it is called gNodeB or gNB. As communication technologies evolve, the name "access network device" may change. For ease of description, in this embodiment, the aforementioned devices providing wireless communication functionality to terminal device 10 are collectively referred to as access network devices. In some embodiments, a communication relationship can be established between terminal device 10 and core network element 30 through access network device 20. For example, in an LTE (Long Term Evolution) system, access network device 20 may be one or more eNodeBs in an EUTRAN (Evolved Universal Terrestrial Radio Access Network) or EUTRAN; in a 5G NR system, access network device 20 may be one or more gNBs in a RAN (Radio Access Network). In the embodiments of this application, unless otherwise specified, the term "network device" refers to access network device 20, such as a base station.

[0052] Core network element 30 is a network element deployed in the core network. Its main functions are to provide user connectivity, manage users, and bear services, serving as an interface to external networks. For example, core network elements in a 5G NR system may include AMF (Access and Mobility Management Function) entities, UPF (User Plane Function) entities, and SMF (Session Management Function) entities.

[0053] In some embodiments, the access network device 20 and the core network element 30 communicate with each other via some air interface technology, such as the NG interface in a 5G NR system. The access network device 20 and the terminal device 10 communicate with each other via some air interface technology, such as the Uu interface.

[0054] The "5G NR system" in this application embodiment can also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in this application embodiment can be applied to LTE systems, 5G NR systems, and subsequent evolution systems of 5G NR systems (such as B5G (Beyond 5G, a fifth-generation mobile communication technology) systems, 6G systems (6th Generation System, a sixth-generation mobile communication system)), and other communication systems such as NB-IoT (Narrow Band Internet of Things) systems. This application does not limit these applications.

[0055] In this embodiment, the network device can provide services to a cell. The terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be the cell corresponding to the network device (e.g., a base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0056] The relevant technologies involved in this application are described below. These related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0057] 1.5G NR

[0058] Currently, with people's pursuit of speed, latency, high-speed mobility, and energy efficiency, as well as the diversity and complexity of business in future life, the 3GPP (3rd Generation Partnership Project) international standards organization has begun to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra-reliable and low-latency communications (URLLC), and massive machine-type communications (mMTC).

[0059] NR can also be deployed independently. In 5G network environments, to reduce air interface signaling and quickly restore wireless connections and data services, a new RRC (Radio Resource Control) state is defined, namely the RRC_INACTIVE state (inactive state). This state is different from the RRC_IDLE state (idle state) and the RRC_CONNECTED state (connected state).

[0060] RRC_IDLE state: Mobility is based on UE-based cell selection and reselection. Paging is initiated by the CN (Core Network), and the paging area is configured by the CN. There is no UE AS (Access Stratum) context or RRC connection on the base station side.

[0061] RRC_CONNECTED state: An RRC connection exists, and the base station and UE share a UE AS context. The network side knows the UE's location at the cell level. Mobility is network-controlled. Unicast data can be transmitted between the UE and the base station.

[0062] RRC_INACTIVE state: Mobility is based on UE cell selection reselection, there is a connection between CN and NR, the UE AS context exists on a certain base station, paging is triggered by RAN (Radio Access Network), the RAN-based paging area is managed by RAN, and the network side knows the UE's location at the RAN-based paging area level.

[0063] 2.5G NR DRX (Discontinuous Reception) process

[0064] In 5G NR, the network can configure DRX functionality for terminals, enabling them to intermittently listen to the PDCCH (Physical Downlink Control Channel) to save power. Each MAC (Media Access Control) entity has a DRX configuration, and the DRX configuration parameters include:

[0065] (1) drx-onDurationTimer: The duration during which the UE wakes up at the beginning of a DRX Cycle;

[0066] (2) drx-SlotOffset: The delay at which the UE starts drx-onDurationTimer;

[0067] (3) drx-InactivityTimer: The duration for which the UE continues to listen to the PDCCH after receiving a PDCCH indicating the initial uplink or downlink transmission;

[0068] (4) drx-RetransmissionTimerDL: The maximum duration for the PDCCH that the UE listens to indicates downlink retransmission scheduling. Each downlink HARQ process, except for the broadcast HARQ (Hybrid Automatic Repeat reQuest) process, corresponds to one drx-RetransmissionTimerDL;

[0069] (5) drx-RetransmissionTimerUL: The longest duration for the UE to listen to the PDCCH indicating uplink retransmission scheduling. Each uplink HARQ process corresponds to one drx-RetransmissionTimerUL;

[0070] (6) drx-LongCycleStartOffset: Used to configure the subframe offset at the start of the long DRX cycle, as well as the long DRX cycle and short DRX cycle;

[0071] (7) drx-ShortCycle: Short DRX cycle, optional configuration;

[0072] (8) drx-ShortCycleTimer: The duration during which the UE is in a short DRX cycle (and does not receive any PDCCH), which is an optional configuration;

[0073] (9) drx-HARQ-RTT-TimerDL: The minimum waiting time required for the UE to receive the PDCCH indicating downlink scheduling. Each downlink HARQ process, except for the broadcast HARQ process, corresponds to one drx-HARQ-RTT-TimerDL.

[0074] (10)drx-HARQ-RTT-TimerUL: The minimum waiting time required for the UE to receive the PDCCH indicating uplink scheduling. Each uplink HARQ process corresponds to one drx-HARQ-RTT-TimerUL.

[0075] If the terminal is configured with DRX, the terminal needs to listen to the PDCCH during the DRX activation period. The DRX activation period includes the following situations:

[0076] (1) Any one of the five timers drx-onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimerDL, drx-RetransmissionTimerUL, and ra-ContentionResolutionTimer is running.

[0077] (2) An SR (Scheduling Request) was sent on the PUCCH and is in a pending state.

[0078] (3) In a contention-based random access process, the terminal has not yet received an initial transmission of PDCCH scrambled with C-RNTI (Cell-Radio Network Temporary Identifier) ​​after successfully receiving the random access response.

[0079] In the existing mechanism, long DRX cycle is the default configuration, while 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. Details are as follows:

[0080] The terminal uses a short DRX cycle when any of the following conditions are met: drx-InactivityTimer times out; or the terminal receives a DRX Command MAC CE.

[0081] The terminal uses a long DRX cycle when any of the following conditions are met: the drx-ShortCycleTimer times out; or the terminal receives a long DRX command MAC CE.

[0082] As shown in Figure 2, 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, as specified below:

[0083] 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,

[0084] If a long DRX Cycle is used, and the current subframe satisfies [(SFN×10)+subframe number]modulo(drx-LongCycle)=drx-StartOffset:

[0085] The drx-onDurationTimer is started at a time after drx-SlotOffset slots (time slots) from the start of the current subframe.

[0086] The condition for a terminal to start or restart drx-InactivityTimer is: if the terminal receives a PDCCH indicating the initial transmission of a downlink or uplink, then the terminal starts or restarts drx-InactivityTimer.

[0087] The conditions for a terminal to start and stop drx-RetransmissionTimerDL are as follows: When the terminal receives a PDCCH indicating downlink transmission, or when the terminal receives a MAC PDU (Protocol Data Unit) on the configured downlink licensed resources, the terminal stops the drx-RetransmissionTimerDL corresponding to that HARQ process. After completing the transmission of feedback from the HARQ process for this downlink transmission, the terminal starts the drx-HARQ-RTT-TimerDL corresponding to that HARQ process. If the timer drx-HARQ-RTT-TimerDL corresponding to a certain HARQ of the terminal times out, and the downlink data transmitted using this HARQ process fails to decode, the terminal starts the drx-RetransmissionTimerDL corresponding to that HARQ process.

[0088] The conditions for a terminal to start and stop the drx-RetransmissionTimerUL are as follows: When the terminal receives a PDCCH indicating uplink transmission, or when the terminal sends a MAC PDU on a configured uplink licensed resource, the terminal stops the drx-RetransmissionTimerUL corresponding to that HARQ process. The terminal starts the drx-HARQ-RTT-TimerUL corresponding to that HARQ process after completing the first repetition of this PUSCH. If the timer drx-HARQ-RTT-TimerUL corresponding to a certain HARQ of the terminal times out, the terminal starts the drx-RetransmissionTimerUL corresponding to that HARQ process.

[0089] 3. LP-WUR (Low-Power Wake-Up Radio) / LP-WUS Project

[0090] 3GPP introduced LP-WUS, which uses a lower-power receiver to receive data, meaning it doesn't use a primary receiver. When a disconnected UE receives LP-WUS, it activates its primary receiver to listen for paging messages, thus saving power. When a connected UE receives LP-WUS, it wakes up its primary receiver to listen for PDCCH. As shown in sub-Figure 1 of Figure 3, when the base station doesn't send LP-WUS signals, the UE's LR (Ultra-low Power receiver) won't receive LP-WUS. Therefore, the MR (Main Radio) isn't activated; it's either off or in deep sleep. As shown in sub-Figure 2 of Figure 3, when the base station sends LP-WUS signals, for UEs in RRC_IDLE / RRC_INACTIVE states, the UE's LR, upon receiving LP-WUS, activates its primary receiver to listen for paging messages, again saving power. LP-WUS can be used not only for UEs in RRC_IDLE / RRC_INACTIVE state, but also for UEs in RRC_CONNECTED state.

[0091] For a UE in the RRC_CONNECTED state, the main function of LP-WUS is to wake up the UE's master receiver to listen to the PDCCH. Based on current standardization conclusions, LP-WUS must be used in conjunction with DRX. There are two specific ways to use LP-WUS.

[0092] Method 1: The UE listens to LP-WUS for a period of time before the start of drx-onDurationTimer. The UE decides whether to start drx-onDurationTimer based on the LP-WUS reception. If the UE receives an LP-WUS instruction to wake up, the UE starts drx-onDurationTimer; otherwise, the UE does not start drx-onDurationTimer.

[0093] Method 2: The UE listens to LP-WUS outside of DRX Active Time. If the UE receives an LP-WUS instruction to wake up, the UE starts a new timer. The UE is in DRX Active during the operation of the new timer.

[0094] For mode 1, LP-WUS primarily affects the activation of drx-onDurationTimer; other DRX timers remain unaffected. For mode 2, the UE does not activate drx-onDurationTimer; other DRX timers remain unaffected.

[0095] The currently introduced LP-WUS requires DRX to work with connected UEs. For method 2 mentioned above, although the base station can wake up the UE's MR (Main Receiver) to listen to the PDCCH at any time by sending LP-WUS, other DRX timer mechanisms besides drx-onDurationTimer are still retained.

[0096] Currently, the consideration is to continue supporting LP-WUS in 6G and further replace the existing DRX function entirely with LP-WUS. This is because DRX Active Time not only limits UE's PDCCH listening behavior but also restricts the UE's mobility-based CSI measurements, periodic / semi-persistent CSI reporting, and periodic / semi-persistent SRS (Sounding Reference Signal) transmission. According to current standards, the UE only performs mobility-based CSI measurements, periodic / semi-persistent CSI reporting, and periodic / semi-persistent SRS transmission during the DRX active time. Mobility-based CSI measurements are used for mobility management, CSI reporting is mainly used for base station scheduling and downlink beam management, and SRS transmission is mainly used by the base station for channel estimation and uplink beam management. If LP-WUS completely replaces the DRX mechanism, the UE might not be woken up to enter the active time due to a long period without service transmission needs. In this case, if the UE also does not perform CSI measurements, CSI reporting, and SRS transmission for a long time, the network equipment will not be able to accurately determine the channel quality with the terminal equipment, which could affect the base station's effective beam management of the UE. For example, if a UE does not report CSI or send SRS for an extended period of time, and the UE has moved to another beam during this time, the scheduling may fail when the UE enters Active Time again due to an unsuitable serving beam, thus affecting the service experience.

[0097] Therefore, ensuring that the UE performs necessary CSI measurements, CSI reporting, and SRS transmission under the LP-WUS mechanism, so that the network equipment can accurately know the channel quality between itself and the terminal equipment, is a problem that needs to be solved.

[0098] Please refer to Figure 4, which shows a flowchart of a wireless communication method provided in one embodiment of this application. This method can be applied to the network architecture shown in Figure 1. The method may include the following step 410.

[0099] Step 410: During the first time period, the terminal device performs measurement-related operations. The first time period is periodic.

[0100] In some embodiments, the terminal device is in a connected state.

[0101] In some embodiments, the terminal device supports wake-up based on the LP-WUS mechanism. Optionally, the terminal device includes a first receiver and a second receiver, the first receiver and the second receiver having different power consumptions. For example, the first receiver is the master receiver (MR) described above, and the second receiver is the low-power receiver (LR) described above, the power consumption of the first receiver is greater than that of the second receiver.

[0102] In some embodiments, the first time period is a time period, such as a time period from the beginning of one moment to the end of another moment. The first time period corresponds to a continuous interval in the time domain and occupies a continuous time domain resource.

[0103] In some embodiments, the first time period is periodic, meaning that the first time period repeats at certain time intervals in the time domain, and this time interval is the period of the first time period. By configuring a periodic first time period for the terminal device, the terminal device can have periodic opportunities to perform measurement-related operations, thereby obtaining timely information about the current channel quality.

[0104] Optionally, the unit of the first time period can be a time slot, symbol, microsecond, millisecond, second, or other time-domain units.

[0105] Optionally, the unit of the period of the first time segment can be a time-domain unit such as a time slot, symbol, microsecond, millisecond, or second.

[0106] In some embodiments, measurement-related operations refer to operations related to wireless measurements for acquiring wireless signal quality. Optionally, measurement-related operations can be cell-level or beam-level, and this application does not limit them.

[0107] In some embodiments, measurement-related operations include at least one of the following: CSI measurement, CSI reporting, and SRS transmission.

[0108] CSI measurement refers to the process of obtaining current state parameters of a wireless channel through specific methods, including channel gain, phase offset, and multipath fading characteristics. CSI measurement methods can include pilot signal methods and blind estimation methods. For the pilot signal method, the transmitter sends a known pilot signal (such as CSI-RS, or Channel State Information-Reference Signal), and the receiver calculates the channel response matrix based on the difference between the received signal and the pilot signal. For the blind estimation method, the channel state is derived by analyzing the statistical characteristics of the received signal (such as correlation), without the need for a pilot signal, but with lower accuracy.

[0109] Optionally, the CSI measurement is a mobility-based CSI measurement. Mobility-based CSI measurement refers to dynamically adjusting the CSI acquisition and feedback strategy according to the mobility status of the terminal device to optimize the performance of the communication system. The core of this measurement method lies in real-time tracking of channel changes, especially the rapid changes in Doppler shift and multipath fading caused by terminal mobility.

[0110] CSI reporting is the process by which the receiver feeds back the measured channel state information to the transmitter to guide the transmitter in adjusting its transmission strategy. The content reported in CSI reports includes parameters such as the Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), and Rank Indicator (RI). CSI reporting can be categorized into periodic reporting and aperiodic / semi-persistent reporting.

[0111] Optionally, CSI reporting can be either periodic or semi-persistent. Periodic reporting refers to feedback at fixed time intervals, suitable for stable channel environments. Aperiodic / semi-persistent reporting is dynamically triggered by network devices, adapting to fast fading scenarios. Semi-persistent reporting is also known as semi-static reporting.

[0112] SRS transmission refers to the transmission of an SRS by a terminal device. The SRS is a reference signal sent by the terminal device, used by network devices to measure the uplink channel state. SRS transmission can also be understood as uplink reference signal transmission. Network devices use SRS to analyze uplink latency, frequency response, and interference.

[0113] Optionally, SRS transmission can be either periodic or semi-persistent. For periodic SRS transmission, after receiving the periodic SRS resource configuration from the network device, the terminal device does not require additional triggering instructions and directly and continuously sends SRS signals according to the preset period and time slot offset. For semi-persistent SRS transmission, the terminal device does not immediately send SRS after receiving the semi-persistent SRS resource configuration. It must wait for the network device to activate it through MAC CE (Media Access Control Element) before it can start periodic transmission. Similarly, it can be deactivated through MAC CE to stop transmission.

[0114] In some embodiments, measurement-related operations include CSI measurements. The terminal device includes a first receiver and a second receiver, the power consumption of which differs. During a first periodic time, the terminal device performs measurement-related operations via the first receiver and / or the second receiver. Exemplarily, the first receiver is the master receiver (MR) described above, and the second receiver is the low-power receiver (LR) described above, with the power consumption of the first receiver being greater than that of the second receiver. During the first periodic time, the terminal device performs measurement-related operations via the MR and / or the LR.

[0115] In some embodiments, the first time period is in the form of a time window or a timer.

[0116] A time window is a predefined time period or periodic interval in wireless communication used to control the scheduling of data transmission, signal processing, or device states. Its core principle is to optimize network performance or device behavior by allocating time resources. In the case where the first period is a time window, the start time of the first period corresponds to the start time of the time window, the end time of the first period corresponds to the end time of the time window, and the duration of the first period corresponds to the duration of the time window.

[0117] Optionally, the first time period can be in the form of a time window. The terminal device performs measurement-related operations within the first time period, which is equivalent to the terminal device performing measurement-related operations within the time window. The terminal device can perform measurement-related operations between the start and end times of the time window.

[0118] A timer is a mechanism in communication protocols used to set time thresholds. By triggering specific operations (such as retransmission, state switching, or error recovery) upon timeout, it ensures the timing controllability of the process. When the first time period is in the form of a timer, the start time of the first time period corresponds to the start time of the timer, the end time of the first time period corresponds to the end time or timeout time of the timer, and the duration of the first time period corresponds to the duration of the timer.

[0119] Optionally, the first time period is in the form of a timer. During the first time period, the terminal device performs measurement-related operations, which is equivalent to the terminal device performing measurement-related operations during the timer's execution. The terminal device can perform measurement-related operations after the timer starts and stop performing them after the timer ends or expires.

[0120] In some embodiments, at least one of the period, length, and start time of the first time period is configured by the network device. For example, when the first time period is in the form of a time window, at least one of the period, length, and start time of the time window is configured by the network device. For example, when the first time period is in the form of a timer, at least one of the period, length, and start time of the timer is configured by the network device.

[0121] In some embodiments, the network device sends first information to the terminal device, the first information being used to configure a first time period. Optionally, the first information is used to configure at least one of the period, length, and start time of the first time period. The terminal device receives the first information and determines the first time period based on the first information.

[0122] In some embodiments, the terminal device performs measurement-related operations during its activation period. Optionally, the terminal device performs measurement-related operations during a first period and / or during the activation period. The terminal device may perform measurement-related operations during the first period or during the activation period.

[0123] Optionally, the terminal device listens to the PDCCH during the active period, but is not required to listen to the PDCCH during the inactive period. Optionally, the PDCCH is used to transmit downlink reference signals. During the active period, the terminal device listens to the PDCCH and can receive downlink reference signals transmitted by network devices via the PDCCH, thereby performing CSI measurements and / or CSI reporting. Furthermore, the inactive period refers to the remaining time period excluding the active period.

[0124] Optionally, the entry and / or exit of the activation period by the terminal device can be configured or indicated by the network device. For example, the terminal device enters the activation period based on a wake-up signal sent by the network device. The wake-up signal can be WUS or LP-WUS as described above. Furthermore, the duration of the activation period can be configured by the network device, predefined by the protocol, or depend on the implementation of the terminal device; this application does not limit this.

[0125] Optionally, the activation period begins when the terminal device receives the wake-up signal. In other words, the terminal device immediately enters the activation period upon receiving the wake-up signal from the network device.

[0126] Optionally, the start time of the activation period is the time offset after the terminal device receives the wake-up signal. The first time offset is the wake-up time of the terminal device, and its value is determined by the capabilities of the terminal device and / or the configuration of the network device. That is, after the terminal device receives the wake-up signal sent by the network device, it enters the activation period after a certain period of time (i.e., the aforementioned first time offset). During this period, the terminal device can perform wake-up operations, such as waking up the main receiver.

[0127] The following section will explain the start time and activation / effectiveness conditions for the first period.

[0128] Scenario 1:

[0129] In some embodiments, the start time of the first time period is determined based on the period of the first time period and the start time offset. The start time offset is the offset between the start time of the first time period and the start time of the period. For example, the start time of the first time period is the start time of the period of the first time period plus the start time offset.

[0130] Optionally, at the start time of the first time period, regardless of whether the terminal device is in an active time period, the terminal device starts, opens, or activates the first time period (which can be understood as the first time period being started or taking effect). During the active time period of the terminal device, the terminal device can perform measurement-related operations.

[0131] For example, if the first time period is in the form of a time window, let's assume the first time period is a first time window. The start time of the first time window is configured by the network device. For instance, if the network device configures the start time offset of the first time window (within a period), the terminal device can determine the start time of the first time window based on the period and the start time offset. Furthermore, since the first time window is periodic, at the start time of each first time window, regardless of whether the terminal device is in an active period, the terminal device initiates, opens, or activates the first time window.

[0132] As shown in Figure 5, the time periods indicated by diagonal fills are the active time periods, and the time periods indicated by dot fills are the first time windows. For periodic first time windows, at the beginning time of each first time window, regardless of whether the terminal device is in an active time period, the terminal device starts, opens, or activates the first time window. Thus, in the example shown in Figure 5, first time windows 1, 2, 3, and 4 are all normally started, opened, or activated at their starting time points.

[0133] For example, if the first time period is in the form of a timer, assume that the first time period corresponds to a first timer. The start time (i.e., the start time) of the first timer is configured by the network device. For instance, if the network device configures the start time offset of the first timer (within a period), the terminal device can determine the start time (i.e., the start time) of the first timer based on the period and the start time offset of the first timer. Furthermore, since the first timer is periodic, at each start time of the first timer, the terminal device starts, enables, or activates the first timer regardless of whether it is in an active period.

[0134] Optionally, at the start time of the first time period, if the first condition is met, the first time period will not start or will not take effect; otherwise (i.e., if the first condition is not met), the first time period will start or take effect; wherein, the first condition is related to the activation period of the terminal device.

[0135] For example, if the first time period is in the form of a time window, let's assume the first time period is a first time window. The start time of the first time window is configured by the network device. For instance, if the network device configures the start time offset of the first time window (within a period), the terminal device can determine the start time of the first time window based on the period and the start time offset. Furthermore, since the first time window is periodic, at the start time of each first time window, if a first condition is met, the terminal device does not start, open, or activate the first time window; otherwise (i.e., if the first condition is not met), the terminal device starts, opens, or activates the first time window. During the first time window and / or the activation period, the terminal device can perform measurement-related operations.

[0136] For example, if the first time period is in the form of a timer, assume that the first time period corresponds to a first timer. The start time (i.e., the start time) of the first timer is configured by the network device. For instance, if the network device configures the start time offset of the first timer (within a period), the terminal device can determine the start time (i.e., the start time) of the first timer based on the period and the start time offset of the first timer. Furthermore, since the first timer is periodic, at each start time of the first timer, if a first condition is met, the terminal device does not start, enable, or activate the first timer; otherwise (i.e., if the first condition is not met), the terminal device starts, enables, or activates the first timer. During the operation and / or activation period of the first timer, the terminal device can perform measurement-related operations.

[0137] Optionally, the first condition includes at least one of the following: the terminal device is in an active period; the time interval between the start time of the first period and the end time of the terminal device's most recent active period is less than or equal to a first time threshold. The first time threshold can be configured by the network device or predefined by the protocol, and this application does not limit its implementation. The terminal device's most recent active period refers to the most recent active period before the current time. If the terminal device is in an active period, it means that the terminal device is already able to perform measurement-related operations within the active period, therefore, it is not necessary to start or activate the first period to enable the terminal device to perform measurement-related operations. If the time interval between the start time of the first period and the end time of the terminal device's most recent active period is less than or equal to the first time threshold, it means that the terminal device has only recently performed measurement-related operations, therefore, it is also not necessary to start or activate the first period to enable the terminal device to perform measurement-related operations, thereby helping to reduce unnecessary measurement-related operations and save terminal power consumption.

[0138] As shown in Figure 6, the time periods indicated by diagonal fills are active time periods, the time periods indicated by dot fills are the first time windows that are started, opened, or activated, and the time periods indicated by white fills are the first time windows that are not started, opened, or activated. For periodic first time windows, for any given first time window, at the start time of the first time window, if the terminal device is in an active time period, the terminal device does not start, open, or activate the first time window, as shown in first time window 2 in the figure; for any given first time window, at the start time of the first time window, if the time interval T between the start time of the first time window and the end time of the terminal device's most recent active time period is less than or equal to the first time threshold th1, the terminal device does not start, open, or activate the first time window, as shown in first time window 3 in the figure; otherwise, the terminal device starts, opens, or activates the first time window, as shown in first time windows 1 and 4 in the figure.

[0139] Scenario 2:

[0140] In some embodiments, the start time of the first time period is determined based on the end time of the most recent activation time period of the terminal device and the period of the first time period. The most recent activation time period of the terminal device refers to the activation time period before the current time and the closest to the current time. During the activation time period of the terminal device, the terminal device can perform measurement-related operations. An explanation of the activation time period is provided below.

[0141] Optionally, if the terminal device is in an active period at the current moment, the first period will not be started or will not take effect. If the terminal device is in an active period at the current moment, it means that the terminal device is already able to perform measurement-related operations during the active period, so it is not necessary to start or take effect the first period to enable the terminal device to perform measurement-related operations.

[0142] Optionally, if the time interval between the current moment and the end time of the terminal device's most recent activation period is equal to the second time threshold, the first time period is initiated or becomes effective. The second time threshold can be configured by the network device or predefined by the protocol; this application does not impose any limitations on this. If the time interval between the current moment and the end time of the terminal device's most recent activation period is equal to the second time threshold, it indicates that a period of time has elapsed since the terminal device last performed a measurement-related operation; therefore, the first time period can be initiated or become effective to enable the terminal device to perform measurement-related operations. Conversely, if the time interval between the current moment and the end time of the terminal device's most recent activation period is less than the second time threshold, the first time period is not initiated or becomes effective. This helps reduce unnecessary measurement-related operations and saves terminal power consumption. The aforementioned second time threshold and first time threshold can be the same or different; this application does not impose any limitations on this.

[0143] Optionally, after the first period is initiated or activated, the terminal device periodically initiates or activates the first period based on its cycle, until the terminal device re-enters the activation period. If the terminal device re-enters the activation period, it is not necessary to initiate, activate, or enable the first period during that activation period.

[0144] For example, if the first time period is in the form of a time window, let's assume the first time period is a first time window. The start time of the first time window is determined based on the end time of the terminal device's most recent activation period and the period of the first time window. At the current moment, if the terminal device is in an activation period, the terminal device does not start, open, or activate the first time window. If the time interval between the current moment and the end time of the terminal device's most recent activation period is less than a second time threshold, the terminal device still does not start, open, or activate the first time window. If the time interval between the current moment and the end time of the terminal device's most recent activation period is equal to the second time threshold, the terminal device starts, opens, or activates the first time window. After the first time window is started, opened, or activated, the terminal device periodically starts, opens, or activates the first time window based on its period until the terminal device re-enters an activation period. Additionally, during the first time window and / or activation period, the terminal device can perform measurement-related operations.

[0145] As shown in Figure 7, the time periods indicated by diagonal fills are active time periods, the time periods indicated by dot fills are the first time windows that are started, opened, or activated, and the time periods indicated by white fills are the first time windows that are not started, opened, or activated. For periodic first time windows, for any given first time window, if the terminal device is in an active time period at the start time of that first time window, the terminal device does not start, open, or activate that first time window, as shown in first time window 2 in the figure; if the time interval T between the current time and the end time of the terminal device's most recent active time period is equal to the second time threshold th2, the terminal device starts, opens, or activates the first time window, as shown in first time window 3 in the figure; after the first time window is started, opened, or activated, the terminal device periodically starts, opens, or activates the first time window based on the period of the first time window until the terminal device re-enters an active time period, as shown in first time window 4 in the figure.

[0146] For example, if the first time period is in the form of a timer, it is assumed that the first time period corresponds to a first timer. The start time of the first timer (i.e., the start time) is determined based on the end time of the terminal device's most recent active time period and the period of the first time window. At the current moment, if the terminal device is in an active time period, the terminal device does not start, enable, or activate the first timer. If the time interval between the current moment and the end time of the terminal device's most recent active time period is less than a second time threshold, the terminal device still does not start, enable, or activate the first timer. If the time interval between the current moment and the end time of the terminal device's most recent active time period is equal to the second time threshold, the terminal device starts, enables, or activates the first timer. Subsequently, the terminal device periodically starts, enables, or activates the first timer based on its period until the terminal device re-enters an active time period. In addition, during the operation of the first timer and / or within the active time period, the terminal device can perform measurement-related operations.

[0147] In some embodiments, in addition to considering the first time period and the activation period described above, CSI reporting conditions may also be considered for CSI reporting. During the first time period or the activation period of the terminal device, if the CSI reporting conditions are met, the terminal device performs CSI reporting. Otherwise, during the first time period or the activation period of the terminal device, if the CSI reporting conditions are not met, the terminal device does not perform CSI reporting; and / or, during a time period that is neither the first time period nor the activation period, the terminal device also does not perform CSI reporting.

[0148] CSI reporting conditions refer to the conditions set for CSI reporting, which may be related to certain events. CSI reporting conditions can be configured by network devices or predefined by protocols.

[0149] In some embodiments, CSI reporting conditions include at least one of the following (1) to (5).

[0150] (1) The current CSI measurement result of the terminal device is different from the most recently reported CSI measurement result.

[0151] For condition (1), the most recently reported CSI measurement result from the terminal device refers to the CSI measurement result most recently reported to the network device at the current time. If the current CSI measurement result of the terminal device differs from the most recently reported CSI measurement result, it indicates that the CSI measurement result has changed, and the latest CSI measurement result can be reported to the network device so that the network device can make corresponding adjustments based on the latest CSI measurement result. Conversely, if the current CSI measurement result of the terminal device is the same as the most recently reported CSI measurement result, it indicates that the CSI measurement result has not changed, and there is no need to report it again.

[0152] (2) The difference between the current CSI measurement result of the terminal device and the most recently reported CSI measurement result is greater than or equal to the first threshold value.

[0153] The first threshold value can be configured by the network device or predefined by the protocol; this application does not limit this. If the difference between the current CSI measurement result of the terminal device and the most recently reported CSI measurement result is greater than or equal to the first threshold value, it indicates a significant change in the CSI measurement result. In this case, the latest CSI measurement result can be reported to the network device so that the network device can make corresponding adjustments based on the latest CSI measurement result. Conversely, if the difference between the current CSI measurement result of the terminal device and the most recently reported CSI measurement result is less than the first threshold value, it indicates that the CSI measurement result has not changed or has changed only slightly, and no reporting is required.

[0154] (3) The CSI measurement result of the terminal equipment on the first beam is greater than or equal to the second threshold value.

[0155] (4) The CSI measurement result of the terminal equipment on the second beam is less than or equal to the third threshold value.

[0156] (5) The difference between the CSI measurement result of the terminal device on the first beam and the CSI measurement result of the terminal device on the second beam is greater than or equal to the fourth threshold value.

[0157] The aforementioned second, third, and fourth threshold values ​​can be configured by the network device or predefined by the protocol; this application does not impose any limitations on this. Optionally, the first beam is a beam other than the serving beam of the terminal device, and the second beam is the serving beam of the terminal device. If the CSI measurement result of the terminal device on the first beam is greater than or equal to the second threshold value, it indicates that the channel quality measured by the terminal device on the beam other than the serving beam is good. If the CSI measurement result of the terminal device on the second beam is less than or equal to the third threshold value, it indicates that the channel quality measured by the terminal device on the serving beam is poor. When the channel quality measured by the terminal device on the beam other than the serving beam is good, and / or when the channel quality measured by the terminal device on the serving beam is poor, the latest CSI measurement result can be reported to the network device so that the network device can make corresponding adjustments based on the latest CSI measurement result. Otherwise, no reporting is required.

[0158] In addition to considering the first time period and the activation period, the above methods can also be used to address CSI reporting, thereby minimizing unnecessary CSI reporting and saving terminal power consumption.

[0159] It should be understood that in the embodiments of this application, "start," "open," "activate," and "take effect" all express the same or similar meanings, and these words or other words with similar meanings can be used interchangeably.

[0160] The technical solution provided in this application provides a periodic first time period for the terminal device. During the first time period, the terminal device can perform measurement-related operations. With the introduction of the LP-WUS mechanism, the terminal device can perform necessary measurement-related operations. This saves terminal power consumption and enables network devices to promptly learn about channel state changes, which helps improve service quality.

[0161] Please refer to Figure 8, which shows a flowchart of a wireless communication method provided in another embodiment of this application. This method can be applied to the network architecture shown in Figure 1. The method may include the following step 810.

[0162] Step 810: If the CSI reporting conditions are met, the terminal device performs CSI reporting.

[0163] Accordingly, the network device receives CSI reporting information sent by the terminal device. The CSI reporting information is sent when the CSI reporting conditions are met.

[0164] In some embodiments, the terminal device is in a connected state.

[0165] In some embodiments, CSI reporting conditions refer to conditions set for CSI reporting, which may be related to certain events. CSI reporting conditions may be configured by network devices or predefined by protocols.

[0166] In some embodiments, CSI reporting conditions include at least one of the following (1) to (5).

[0167] (1) The current CSI measurement result of the terminal device is different from the most recently reported CSI measurement result.

[0168] For condition (1), the most recently reported CSI measurement result from the terminal device refers to the CSI measurement result most recently reported to the network device at the current time. If the current CSI measurement result of the terminal device differs from the most recently reported CSI measurement result, it indicates that the CSI measurement result has changed, and the latest CSI measurement result can be reported to the network device so that the network device can make corresponding adjustments based on the latest CSI measurement result. Conversely, if the current CSI measurement result of the terminal device is the same as the most recently reported CSI measurement result, it indicates that the CSI measurement result has not changed, and there is no need to report it again.

[0169] (2) The difference between the current CSI measurement result of the terminal device and the most recently reported CSI measurement result is greater than or equal to the first threshold value.

[0170] The first threshold value can be configured by the network device or predefined by the protocol; this application does not limit this. If the difference between the current CSI measurement result of the terminal device and the most recently reported CSI measurement result is greater than or equal to the first threshold value, it indicates a significant change in the CSI measurement result. In this case, the latest CSI measurement result can be reported to the network device so that the network device can make corresponding adjustments based on the latest CSI measurement result. Conversely, if the difference between the current CSI measurement result of the terminal device and the most recently reported CSI measurement result is less than the first threshold value, it indicates that the CSI measurement result has not changed or has changed only slightly, and no reporting is required.

[0171] (3) The CSI measurement result of the terminal equipment on the first beam is greater than or equal to the second threshold value.

[0172] (4) The CSI measurement result of the terminal equipment on the second beam is less than or equal to the third threshold value.

[0173] (5) The difference between the CSI measurement result of the terminal device on the first beam and the CSI measurement result of the terminal device on the second beam is greater than or equal to the fourth threshold value.

[0174] The aforementioned second, third, and fourth threshold values ​​can be configured by the network device or predefined by the protocol; this application does not impose any limitations on this. Optionally, the first beam is a beam other than the serving beam of the terminal device, and the second beam is the serving beam of the terminal device. If the CSI measurement result of the terminal device on the first beam is greater than or equal to the second threshold value, it indicates that the channel quality measured by the terminal device on the beam other than the serving beam is good. If the CSI measurement result of the terminal device on the second beam is less than or equal to the third threshold value, it indicates that the channel quality measured by the terminal device on the serving beam is poor. When the channel quality measured by the terminal device on the beam other than the serving beam is good, and / or when the channel quality measured by the terminal device on the serving beam is poor, the latest CSI measurement result can be reported to the network device so that the network device can make corresponding adjustments based on the latest CSI measurement result. Otherwise, no reporting is required.

[0175] In some embodiments, during a first time period or an activation period of the terminal device, the terminal device performs CSI reporting if the CSI reporting conditions are met. The first time period is periodic. Optionally, at least one of the period, length, and start time of the first time period is configured by the network device. For a description of the first time period and the activation period, please refer to the embodiments above, which will not be repeated here.

[0176] The technical solution provided in this application introduces CSI reporting conditions for CSI reporting. When the terminal device meets the above conditions, it performs CSI reporting, which can minimize some unnecessary CSI reporting and save terminal power consumption.

[0177] In the above method embodiments, the steps performed by the terminal device can be implemented separately as a handover method on the terminal device side, and the steps performed by the network device can be implemented separately as a handover method on the network device side.

[0178] Furthermore, the various embodiments of this application can be combined in any way to form new embodiments, all of which are within the protection scope of this application.

[0197] In some embodiments, the first beam is a beam other than the service beam of the terminal device, and the second beam is the service beam of the terminal device.

[0198] In some embodiments, the terminal device listens to the PDCCH during the active period, and the terminal device does not require listening to the PDCCH during the inactive period; and / or, the start time of the active period is the moment when the terminal device receives the wake-up signal, or the start time of the active period is a time offset by a first time after the terminal device receives the wake-up signal, the first time offset being the wake-up time of the terminal device, the value of which is determined by the capabilities of the terminal device and / or the network device configuration.
