[0063] 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 following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all 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.

[0064] In order to facilitate a better understanding of the embodiments of the present application, the terminal energy saving based on waking up the receiver related to the present application is explained.

[0065] To further save power on the UE, a wake-up receiver is introduced to receive the wake-up signal. This wake-up receiver features extremely low cost, extremely low complexity, and extremely low power consumption. It primarily receives the wake-up signal (WUS) through envelope detection. Therefore, the modulation scheme and waveform of the wake-up signal (WUS) received by the wake-up receiver differ from those of the signal carried by the Physical Downlink Control Channel (PDCCH). The wake-up signal primarily consists of an envelope signal modulated by amplitude shift keying (ASK) on a carrier signal. The demodulation of the envelope signal is also primarily accomplished by driving a low-power circuit using energy provided by the wireless RF signal, making it passive. The wake-up receiver can also be powered by the terminal. Regardless of the power supply method, the wake-up receiver significantly reduces power consumption compared to the UE's traditional receiver. The wake-up receiver can be integrated with the UE as an additional module to the UE receiver, or it can function as a standalone wake-up module for the UE.

[0066] The block diagram of the receiver system based on zero-power wake-up can be shown in Figure 2. The wake-up receiver receives the wake-up signal and can instruct the UE to turn on the main receiver if the UE needs to turn on the receiver. Otherwise, the UE's main receiver can be turned off.

[0067] The signal received by the wake-up receiver can be called a wake-up radio (WUR) signal, which adopts a relatively simple modulation method to meet the reception requirements of the wake-up receiver with extremely low power consumption and extremely low complexity. Among them, the wake-up signal (WUS) is one of the WUR signals. The method of generating the WUR signal, such as the wake-up signal in the 802.11 technology, adopts on-off keying (OOK) modulation. The modulation principle of OOK is to modulate the amplitude of the carrier signal to non-zero and zero values, corresponding to on (On) and off (Off), respectively, to represent the information bit. OOK is also known as binary amplitude keying (2ASK). As shown in Figure 3, the WUR-Sync part carries a synchronization sequence repeated twice, in which bit 1 is modulated to On and bit 0 is modulated to Off.

[0068] The above-mentioned OOK signal is generated through multi-carrier (MC), so it is called MC-OOK signal. The generation of MC-OOK signal can adopt existing multi-carrier modulation such as orthogonal frequency-division multiplexing (OFDM) modulation to generate OOK signal, which can maintain good compatibility with OFDM system and reduce the complexity of transmitter introduced by implementing WUR signal. Figure 4 is a schematic diagram of MC-OOK signal generated by multi-carrier. By mapping the corresponding amplitude values ​​to multiple subcarriers in the frequency domain, the waveform of the time domain signal converted by the inverse discrete Fourier transform (IDFT) is similar to the waveform formed by ASK modulation, where bit 1 is represented by the high level of the signal and bit 0 is represented by the low level of the signal.

[0069] To facilitate a better understanding of the embodiments of the present application, the RRM measurements related to the present application are described.

[0070] For wireless mobile communication systems, accurate measurement of cell quality and beam quality is fundamental to effective radio resource management and mobility management. For 5G NR, two main types of reference signals are currently considered for measurement: the Synchronization Signal Block (SSB) and the Channel State Information Reference Signal (CSI-RS).

[0071] SSB Measurement Timing Configuration (SMTC) is the time domain resource configuration information for SSB measurements and is also an important new concept introduced in 5G NR measurement configuration. It is mainly used to configure a set of measurement time windows based on SSB measurements. The size, position, period and other parameters of the window can be adjusted through configuration parameters. An example is shown in Figure 5.

[0072] It should be noted that SMTC is configured separately for each frequency point. When the UE is making measurements, there is a set of SMTC configurations on each measurement frequency point to indicate the available measurement window information on that frequency point. However, this restriction is gradually being relaxed during protocol discussions. In the Release 15 (R15) stage, in order to match the different synchronization signal block periods of different cells, two sets of SMTC parameters are allowed to be configured for the measurement of a given cell during connected state same-frequency measurements. For example, in addition to the basic SMTC configuration, a more dense set of measurement windows can be configured for use by the serving cell and the cells indicated in the specific cell list. In the subsequent Release 16 (R16) stage, the idle state measurement also expanded the maximum number of SMTC configurations on each frequency point to two, in order to further meet the flexibility of network operations.

[0073] In addition, high-level signaling can indicate the specific configuration information of the specific measurement reference signal through the reference signal configuration (ReferenceSignalConfig) parameter. For SSB-based measurements, the SSB indication to be measured (ssb-ToMeasure) uses a bitmap to indicate the position information of the SSB actually sent in the SSB burst set. The UE can clearly know which SSB candidate positions actually sent SSBs and which SSB candidate positions did not send SSBs through ssb-ToMeasure. The UE does not need to perform measurements at positions where SSBs are not sent, thereby achieving energy saving for the UE.

[0074] For CSI-RS-based measurements, the base station can configure one or more CSI-RS resources for the UE to measure through high-layer signaling. First, based on the cell, high-layer signaling can provide cell-level CSI-RS configuration parameters, such as the cell identity (ID), the cell's measurement bandwidth, and resource density. In addition, since each cell can be configured with multiple CSI-RS resources, further parameter configuration will also provide configuration information at the level of each CSI-RS resource, such as the specific CSI-RS index, the time and frequency domain location information occupied by the CSI-RS resource, and the sequence generation method.

[0075] The mobility management of UE in the NR system mainly includes the cell selection and reselection process in the Radio Resource Control (RRC) idle (RRC_IDLE) or RRC deactivated (RRC_INACTIVE) state and the handover process of the connected UE.

[0076] 1. Mobility management in RRC_IDLE or RRC_INACTIVE state

[0077] For a UE in RRC_IDLE or RRC_INACTIVE state, the prerequisite for being able to reside in a cell is that the signal quality of the cell (including the measurement results of Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ)) meets the cell selection S criterion. After selecting a suitable cell, the UE will continue to evaluate the cell reselection. The measurements to be performed for evaluating the cell reselection are divided and performed according to the reselection priority of each frequency point. Specifically:

[0078] For high-priority frequencies, neighbor cell measurements are always performed.

[0079] For the same-frequency point, when the RSRP and RSRQ values ​​of the serving cell are both higher than the same-frequency measurement threshold configured by the network, the UE can stop measuring the same-frequency neighboring cells; otherwise, measurement must be performed.

[0080] For frequencies with the same priority and lower priority, when the RSRP and RSRQ values ​​of the serving cell are both higher than the inter-frequency measurement threshold configured by the network, the UE can stop measuring neighboring cells with the same priority and lower priority frequencies; otherwise, measurements must be performed.

[0081] After obtaining multiple candidate cells through measurement, the process of determining the target cell for cell reselection is basically the same as that of the LTE system, and the principle of prioritizing reselection of cells on high-priority frequencies is adopted.

[0082] For cell reselection on a high-priority frequency, the signal quality must be above a certain threshold and last for a specified period of time, and the UE must stay in the source cell for no less than 1 second.

[0083] For cell reselection on the same frequency and priority frequency, the R criteria (sorted by RSRP) must be met, the signal quality of the new cell is better than that of the current cell for a specified period of time, and the UE stays in the source cell for no less than 1 second.

[0084] For cell reselection on a low-priority frequency, there must be no high-priority or same-priority frequency cells that meet the requirements, the source cell signal quality must be below a certain threshold, the cell signal quality on the low-priority frequency must be above a certain threshold and last for a specified period of time, and the UE must reside in the source cell for no less than 1 second.

[0085] During cell reselection on the same frequency and priority frequency, when multiple candidate cells meet the requirements, the LTE system selects the best cell as the target cell for reselection by sorting by RSRP. Considering that UEs in the NR system access cells via beams, to increase the probability of successful access via a good beam, the target cell must be determined based on both cell signal quality and the number of good beams. To achieve this, the NR system first selects the best cells with similar signal quality before selecting the target cell, and then selects the cell with the largest number of good beams as the target cell.

[0086] 2. Connected Mobility Management

[0087] The mobility management of connected UEs is mainly achieved through the handover process controlled by the network. The NR system inherits the handover process of the LTE system, which mainly includes three stages: handover preparation, handover execution and handover completion.

[0088] During the handover preparation phase, the source base station makes a handover decision after receiving the measurement report sent by the UE and initiates a handover request to the target base station. If the target cell accepts the request, it sends a handover response message to the source base station through the inter-base station interface. The message contains the configuration information of the target cell, that is, the handover command.

[0089] During the handover execution phase, the source base station sends a handover command to the UE. Upon receiving the handover command, the UE disconnects from the source cell and begins establishing downlink synchronization with the target cell. It then initiates a random access procedure to the target cell using the random access resources configured in the handover command and reports a handover completion message upon completion of the random access procedure. While the UE is accessing the target cell, the source base station forwards data packets received from the User Plane Function (UPF) entity to the target base station and sends the target base station information about the state of uplink and downlink data transmission and reception within the source cell before forwarding.

[0090] During the handover completion phase, the target base station sends a path switching request to the Access and Mobility Management Function (AMF) entity, requesting the AMF entity to switch the data packet transmission path from the UPF entity to the access network to the target base station. Once the AMF entity responds to the request, it indicates that the path switching is successful, and the target base station can instruct the source base station to release the UE's context information. At this point, the entire UE connection is switched to the target cell.

[0091] To facilitate a better understanding of the embodiments of the present application, the RRM measurement relaxation mechanism related to the present application is described.

[0092] A terminal in a non-connected state needs to perform RRM measurements on the serving cell and other neighboring cells based on network configuration to support mobility operations, such as cell reselection. In the evolution of the NR standard, for the sake of terminal energy conservation, when the channel quality of the terminal in the serving cell is good, the terminal may not initiate RRM measurements on the same frequency point and inter-frequency / inter-technology points of equal or lower priority. At the same time, the measurement interval for RRM measurements on high-priority inter-frequency / inter-technology points can be increased.

[0093] Specifically:

[0094] When the RSRP of the terminal in the serving cell is higher than the configured SIntraSearchP and the RSRQ of the terminal in the serving cell is higher than SIntraSearchQ, the terminal may not initiate RRM measurement for neighboring cells of the same frequency point. Among them, SIntraSearchP and SIntraSearchQ are both high-layer configured threshold parameters.

[0095] When the RSRP of the terminal on the serving cell is higher than SnonIntraSearchP and the RSRQ of the terminal on the serving cell is higher than SnonIntraSearchQ, the terminal may not initiate RRM measurements for inter-frequency and inter-system low-priority and equal-priority neighboring cells. At the same time, for inter-frequency and inter-system high-priority frequencies, the terminal may initiate relaxed RRM measurements.

[0096] For terminals that need to perform RRM measurements of neighboring cells, it is necessary to introduce a set of RRM measurement relaxation mechanisms for neighboring cells to further meet the power saving needs of the terminals.

[0097] The evolution of the NR standard introduces two relaxed measurement criteria for RRM measurements of non-connected terminals: the "terminal not at the cell edge" criterion and the "low mobility" criterion. Both criteria are based on the terminal's "cell-level" measurement results in the serving cell. The following describes these two criteria separately.

[0098] 1. "Terminal is not located at the cell edge" criterion

[0099] For this criterion, the network will configure an RSRP threshold and may also configure an RSRQ threshold. When the RSRP of the terminal on the serving cell is greater than the RSRP threshold, and when the network has configured an RSRQ threshold, the RSRQ of the terminal on the serving cell is greater than the RSRQ threshold, the terminal is considered to meet the "terminal is not at the cell edge" criterion.

[0100] The RSRP threshold configured by the network for the "terminal is not at the cell edge" criterion must be smaller than SIntraSearchP and SnonIntraSearchP. If the network also configures the RSRQ threshold for the "terminal is not at the cell edge" criterion, the RSRQ threshold used for the "terminal is not at the cell edge" criterion must be smaller than SIntraSearchQ and SnonIntraSearchQ.

[0101] 2. "Low Mobility" Principle

[0102] For this criterion, the network will configure the RSRP change evaluation duration (TSearchDeltaP) and the RSRP change value threshold (SSearchDeltaP). When the RSRP change of the terminal in the serving cell within TSearchDeltaP is less than SSearchDeltaP, the terminal is considered to meet the "low mobility" criterion, as shown in Figure 6.

[0103] It should be noted that the "low mobility" criterion was enhanced in the subsequent evolution of the NR standard. The main change was the introduction of the second threshold SSearchDeltaP and the second TSearchDelta to support further relaxation of measurements for low mobility scenarios (such as stationary terminals or quasi-stationary terminals) (reflected in a larger scaling factor).

[0104] After completing cell selection / reselection, the terminal needs to perform normal RRM measurements within at least a period of time TSearchDeltaP.

[0105] For RRM measurements of frequencies with equal or lower priority, RRM measurement relaxation methods are defined for different RRM measurement relaxation criteria.

[0106] The details are as follows:

[0107] When the terminal meets the "low mobility" criterion, the terminal uses a longer measurement interval when performing RRM measurements on neighboring cells. A fixed scaling factor is used to increase the measurement interval.

[0108] When the terminal meets the "terminal is not located at the cell edge" criterion, the terminal uses a longer measurement interval when performing RRM measurements on neighboring cells. A fixed scaling factor is used to increase the measurement interval.

[0109] When the terminal meets both the "low mobility" criterion and the "terminal is not located at the cell edge" criterion, the terminal's measurement interval for the same-frequency frequency point, different-frequency frequency point, and different-technology frequency point is increased to 1 hour.

[0110] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0111] In the evolution of the NR standard, the energy-saving signal is introduced mainly to reduce the power consumption of the Physical Downlink Control Channel (PDCCH) detection, while the power consumption of the RRM measurement is saved through the RRM measurement relaxation mechanism. In the evolution of the NR standard, the wake-up radio (WUR) signal is introduced to further reduce the power consumption caused by the UE's main receiver being turned on to detect the PDCCH. In addition to detecting the PDCCH, the UE's main receiver must also be turned on periodically to perform RRM measurements. The RRM measurement relaxation mechanism can increase the time interval for performing RRM measurements on neighboring cells. However, the judgment condition for sending RRM measurements is based on the RRM measurement results of the serving cell, and the RRM measurement of the serving cell has not been relaxed. The WUR signal introduced in the evolution of the NR standard receives the wake-up signal (a WUR signal) by turning on the wake-up receiver, and then triggers the start-up of the main receiver. If the main receiver needs to be turned on periodically due to RRM measurements, the power saving effect brought by the introduced WUS signal will be greatly reduced, and the power saving gain cannot be reflected. Even if RRM measurements are performed by using a WUR receiver instead of the main receiver, due to the extremely low complexity of the WUR receiver and the limitations of the supported signal waveforms, it is impossible to accurately measure the reference signal, including whether RSRP measurements can be performed. The measurement accuracy is also questionable, which will affect mobility management based on RRM measurements.

[0112] Based on the above problems, the present application proposes a solution for determining the RRM measurement status. The first communication device can determine the RRM measurement status based on the WUR signal or RLM result, thereby reducing the RRM measurement performed by the main receiver of the first communication device on the service cell, thereby reducing the energy consumption of the RRM measurement.

[0113] The technical solution of this application is described in detail below through specific embodiments.

[0114] FIG7 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG7 , the wireless communication method 200 may include at least part of the following contents:

[0115] S210, the first communication device determines the RRM measurement status according to the first information; wherein the first information is one of the following: WUR signal, RLM result.

[0116] In some embodiments, the first communication device may be a terminal device, such as the terminal device 120 described above in FIG. 1 .

[0117] In the prior art, the main receiver of the terminal device needs to be turned on periodically to perform RRM measurements, and determine whether to increase the time interval for performing RRM measurements on neighboring cells based on the RRM measurement results, that is, determine whether to perform relaxed RRM measurements on neighboring cells based on the RRM measurement results.

[0118] It should be noted that in order to reduce the power consumption caused by the RRM measurement of the serving cell or the neighboring cell, so that the introduced WUS signal can further bring power saving to the terminal device, it is necessary to reduce the activation of the main receiver of the terminal device for RRM measurement. In the prior art, the terminal device needs to determine whether the terminal device meets the "low mobility" criterion and / or the "terminal is not located at the edge of the cell" criterion based on the RRM measurement result of the serving cell, and when the "low mobility" criterion and / or the "terminal is not located at the edge of the cell" criterion is met, the RRM measurement of the neighboring cell is relaxed. For terminals with relatively fixed positions, such as sensors, fixed access terminals, etc., or ordinary terminals that maintain no position change for a long time or move only within a limited range, in this case, the need for the terminal to perform RRM measurement is relatively small, and RRM measurement can be performed for a long time without RRM measurement, including RRM measurement of the serving cell. On the other hand, the power saving brought by the introduction of the WUS signal mainly comes from the awakening receiver to receive the awakening signal (a WUS signal) to trigger the activation of the main receiver of the terminal device. The main receiver of the terminal device does not need to be turned on regularly to receive the PDCCH. Due to the extremely low power consumption of the wake-up receiver, it can be always on to receive WUR signals.

[0119] Based on the problems existing in the prior art, in an embodiment of the present application, the first communication device may determine the RRM measurement state based on the WUR signal or the radio link monitoring (RLM) result. Optionally, the first communication device may determine whether to perform relaxed RRM measurement based on the WUR signal or the RLM result, or the first communication device may determine whether to perform RRM measurement based on the WUR signal or the RLM result; wherein the RRM measurement may be an RRM measurement for the serving cell or an RRM measurement for a neighboring cell.

[0120] That is, in the embodiment of the present application, the primary receiver of the first communication device does not need to be periodically turned on to perform RRM measurements, thereby reducing the energy consumption of RRM measurements. In other words, the first communication device turns on the primary receiver to perform RRM measurements of the serving cell based on the WUR signal or RLM result, rather than periodically.

[0121] In the embodiment of the present application, relaxed RRM measurement may refer to: increasing the measurement interval of the RRM measurement, or reducing the measurement frequency of the RRM measurement, or similar expressions, which is not limited in the present application.

[0122] In some embodiments, the RRM measurement state includes a first RRM measurement state and a second RRM measurement state.

[0123] In some embodiments, in a first RRM measurement state, the first communications device stops performing RRM measurements, or the first communications device performs relaxed RRM measurements; and / or, in a second RRM measurement state, the first communications device performs RRM measurements, and the RRM measurements performed by the first communications device are not relaxed. That is, in the second RRM measurement state, the first communications device performs normal RRM measurements, or the first communications device performs conventional RRM measurements. Optionally, the RRM measurements are RRM measurements for a serving cell, or the RRM measurements are RRM measurements for a neighboring cell. Optionally, the RRM measurements are performed by a primary receiver of the first communications device, or the RRM measurements are performed by a wake-up receiver of the first communications device.

[0124] In some embodiments, in a first RRM measurement state, the first communications device determines the mobility state of the first communications device via a WUR signal. That is, in the first RRM measurement state, the first communications device can determine the mobility state of the first communications device via the WUR signal without performing RRM measurements. Optionally, after determining the mobility state of the first communications device, the wake-up receiver of the first communications device can report the mobility state of the first communications device to the primary receiver of the first communications device, thereby enabling the primary receiver of the first communications device to determine that RRM measurements do not need to be performed.

[0125] In some embodiments, in the second RRM measurement state, the first communications device determines the mobility state of the first communications device by measuring a reference signal. That is, in the second RRM measurement state, the first communications device may determine the mobility state of the first communications device by performing regular RRM measurements.

[0126] In some embodiments, in the second RRM measurement state, the first communication device determines the mobility state of the first communication device via the WUR signal. That is, in the second RRM measurement state, the first communication device can determine the mobility state of the first communication device via the WUR signal without performing RRM measurements. Optionally, after determining the mobility state of the first communication device, the wake-up receiver of the first communication device can report the mobility state of the first communication device to the primary receiver of the first communication device, thereby allowing the primary receiver of the first communication device to determine that RRM measurements do not need to be performed.

[0127] In some embodiments, in the first RRM measurement state, when it is determined that the first communication device is not in the first mobility state, the first communication device adjusts the RRM measurement state to the second RRM measurement state. That is, when the first communication device is not in the first mobility state, the RRM measurement state of the first communication device can fall back from the first RRM measurement state (such as the state of stopping performing RRM measurement or the relaxed RRM measurement state) to the second RRM measurement state (such as the conventional RRM measurement state). Thus, when the mobility state of the first communication device changes, it can fall back to the normal RRM measurement process in time to ensure the mobility performance of the first communication device. Optionally, after determining that the first communication device is not in the first mobility state, the wake-up receiver of the first communication device can report the mobility state of the first communication device to the main receiver of the first communication device, so that the main receiver of the first communication device can determine to fall back to the conventional RRM measurement state.

[0128] In some embodiments, in the first RRM measurement state, when it is determined that the first communications device is in the first mobility state, the first communications device maintains the RRM measurement state in the first RRM measurement state. That is, when the first communications device is in the first mobility state, the first communications device maintains the first RRM measurement state (e.g., a state in which RRM measurement is stopped or a relaxed RRM measurement state), thereby reducing energy consumption of RRM measurement.

[0129] In some embodiments, in the second RRM measurement state, when it is determined that the first communication device is in the first mobility state, the first communication device adjusts the RRM measurement state to the first RRM measurement state. That is, when the first communication device is in the first mobility state, the RRM measurement state of the first communication device can be adjusted from the second RRM measurement state (such as the regular RRM measurement state) to the first RRM measurement state (such as the state of stopping performing RRM measurement or the relaxed RRM measurement state), thereby reducing the energy consumption of RRM measurement. Optionally, after determining that the first communication device is in the first mobility state, the wake-up receiver of the first communication device can report the mobility state of the first communication device to the primary receiver of the first communication device, so that the primary receiver of the first communication device can determine to stop performing the regular RRM measurement state.

[0130] In some embodiments, in the second RRM measurement state, when it is determined that the first communications device is not in the first mobility state, the first communications device maintains the RRM measurement state as the second RRM measurement state. That is, when the first communications device is not in the first mobility state, the first communications device maintains the second RRM measurement state (e.g., a regular RRM measurement state) to ensure the mobility performance of the first communications device. Optionally, after determining that the first communications device is not in the first mobility state, the wake-up receiver of the first communications device may report the mobility state of the first communications device to the primary receiver of the first communications device, so that the primary receiver of the first communications device may determine to maintain the regular RRM measurement state.

[0131] In some embodiments, the first mobility state is a low mobility state. That is, when the first communication device is in the first mobility state, it can be considered that the first communication device meets the "low mobility" criterion. For the description of the "low mobility" criterion, reference can be made to the above-mentioned related description and will not be repeated here.

[0132] In some embodiments, the first mobility state is a state in which the first communication device is not located at a cell edge. That is, when the first communication device is in the first mobility state, it can be considered that the first communication device meets the "terminal is not located at a cell edge" criterion. For a description of the "terminal is not located at a cell edge" criterion, reference can be made to the above-mentioned related description and will not be repeated here.

[0133] In some embodiments, when the first information is a WUR signal, the above S210 may specifically include:

[0134] The first communication device determines the RRM measurement state based on whether target control information is detected in the WUR signal, or the first communication device determines the RRM measurement state based on a measurement result of the WUR signal.

[0135] Optionally, the wake-up receiver of the first communication device may send second indication information to the main receiver of the first communication device;

[0136] In which, the second indication information can be used to indicate whether the target control information is detected in the WUR signal, or the second indication information can be used to indicate the measurement result of the WUR signal, or the second indication information can be used to indicate whether the target control information is detected in the WUR signal within a period of time, or the second indication information can be used to indicate the measurement result of the WUR signal within a period of time, or the second indication information can be used to indicate the number of target control information detected in the WUR signal within a period of time, or the second indication information can be used to indicate the number of target control information not detected in the WUR signal within a period of time, or the second indication information can be used to indicate the number of times the measurement result of the WUR signal is greater than or equal to the first threshold within a period of time, or the second indication information can be used to indicate the number of times the measurement result of the WUR signal is less than the first threshold within a period of time, or the second indication information can be used to indicate the determined RRM measurement status.

[0137] Further, the primary receiver of the first communication device may determine the RRM measurement state based on the second indication information.

[0138] In some embodiments, the second communication device may periodically send a WUR signal, the first communication device receives the WUR signal by waking up the receiver, and the first communication device determines the RRM measurement status based on whether target control information is detected in the WUR signal, or the first communication device determines the RRM measurement status based on the measurement result of the WUR signal.

[0139] Specifically, the second communication device periodically sends a WUR signal, the first communication device uses a wake-up receiver to receive the WUR signal, and the first communication device determines to relax the RRM measurement based on the information detected in the WUR signal. The main receiver of the first communication device may not perform periodic RRM measurements, especially RRM measurements of the service cell. The detection result of the WUR signal can reflect the mobility characteristics of the first communication device, for example, "low mobility" and "the terminal is not located at the edge of the cell". That is to say, the embodiment of the present application uses the detection result of the WUR signal to replace the measurement result of the RRM reference signal by the main receiver of the first communication device to determine the relaxation of the RRM measurement of the service cell or the neighboring cell, which is equivalent to using the wake-up receiver to receive the WUR signal, so that the main receiver relaxes the RRM measurement of the service cell.

[0140] In some embodiments, the second communication device may be a device that sends a WUR signal, for example, the second communication device is a base station, or the second communication device is a specific network node that sends the WUR signal, or the second communication device is another terminal. For example, a UE (i.e., the second communication device) in a cell that meets the criterion of "the terminal is not located at the edge of the cell" sends a WUR signal, and the WUR signal has a certain coverage range. When the target UE (i.e., the first communication device) detects the WUR signal, the WUR signal reflects information about a specific mobility state, and the target UE (i.e., the first communication device) determines that a certain mobility state is met.

[0141] In some embodiments, the first communications device determines the RRM measurement state according to whether target control information is detected in the WUR signal, including:

[0142] When target control information is detected in the WUR signal, the first communication device determines that the RRM measurement state is a first RRM measurement state; and / or, when target control information is not detected in the WUR signal, the first communication device determines that the RRM measurement state is a second RRM measurement state.

[0143] For example, when target control information is detected in the WUR signal, RRM measurement can be stopped, or RRM measurement relaxation can be performed; and / or, when target control information is not detected in the WUR signal, RRM measurement relaxation fallback is performed, that is, regular RRM measurement is performed.

[0144] In some embodiments, the first communications device determines the RRM measurement state according to whether target control information is detected in the WUR signal, including:

[0145] In a case where target control information is detected in the WUR signal, the first communications device determines that it is in a first mobility state, and in a case where target control information is not detected in the WUR signal, the first communications device determines that it is not in the first mobility state;

[0146] When the first communication device is in the first mobility state, the first communication device determines that the RRM measurement state is the first RRM measurement state; and / or, when the first communication device is not in the first mobility state, the first communication device determines that the RRM measurement state is the second RRM measurement state.

[0147] That is, whether the target control information is detected in the WUR signal can be used to determine the RRM mobility state of the first communication device, such as "low mobility" or "the terminal is not located at the cell edge".

[0148] In some embodiments, the target control information includes at least one of the following: a synchronization sequence, a random access preamble, cell information, beam information, information related to mobility measurement, and information related to mobility state.

[0149] Specifically, when the first communication device detects target control information in the WUR signal received by the wake-up receiver, it is considered that the first communication device meets a certain RRM mobility state, such as "low mobility" or "the terminal is not at the edge of the cell", and there is no need to turn on the main receiver to perform RRM measurements, thereby achieving power saving for the first communication device. Since the determination of the RRM mobility state of the first communication device does not rely on the measurement performed by turning on the main receiver, if the first communication device is in the state of "low mobility" or "the terminal is not at the edge of the cell", it can only rely on the wake-up receiver to determine the RRM mobility state, thereby performing corresponding measurement relaxation, reducing the power consumption caused by the RRM measurement. When the first communication device determines that a certain mobility state is met based on the WUR signal, the first communication device can maintain the current RRM measurement relaxation state, including monitoring the mobility state of the first communication device by the wake-up receiver in the service cell.

[0150] In some embodiments, the first communications device determines the RRM measurement state according to the measurement result of the WUR signal, including:

[0151] When the measurement result of the WUR signal is greater than or equal to the first threshold, the first communication device determines that the RRM measurement state is the first RRM measurement state; and / or, when the measurement result of the WUR signal is less than the first threshold, the first communication device determines that the RRM measurement state is the second RRM measurement state.

[0152] For example, when the measurement result of the WUR signal is greater than or equal to the first threshold, the RRM measurement can be stopped, or the RRM measurement can be relaxed; and / or, when the measurement result of the WUR signal is less than the first threshold, the RRM measurement relaxation backoff is performed, that is, regular RRM measurement is performed.

[0153] In some embodiments, the first communications device determines the RRM measurement state according to the measurement result of the WUR signal, including:

[0154] In a case where the measurement result for the WUR signal is greater than or equal to a first threshold, the first communications device determines that it is in a first mobility state, and in a case where the measurement result for the WUR signal is less than the first threshold, the first communications device determines that it is not in the first mobility state;

[0155] When the first communication device is in the first mobility state, the first communication device determines that the RRM measurement state is the first RRM measurement state; and / or, when the first communication device is not in the first mobility state, the first communication device determines that the RRM measurement state is the second RRM measurement state.

[0156] That is, the measurement result of the WUR signal can be used to determine the RRM mobility state of the first communication device, such as "low mobility" or "the terminal is not located at the cell edge".

[0157] For example, when the first communication device is in the first mobility state, RRM measurement may be stopped, or RRM measurement relaxation may be performed; and / or, when the first communication device is not in the first mobility state, RRM measurement relaxation fallback may be performed, i.e., conventional RRM measurement may be performed.

[0158] In some embodiments, the measurement result of the WUR signal includes but is not limited to at least one of the following:

[0159] Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), and path loss.

[0160] In some embodiments, the measurement results for the WUR signal can be obtained by the wake-up receiver.

[0161] In some embodiments, the first threshold is agreed upon by a protocol, or the first threshold is configured by a network, or the first threshold is determined by the first communication device.

[0162] In some embodiments, when the first information is an RLM result, the above S210 may specifically include:

[0163] The first communication device determines the RRM measurement state according to whether a radio link failure (RLF) occurs according to the RLM result, or the first communication device determines the RRM measurement state according to the number of in-synchronization (IS) states within a first time period associated with the RLM result, or the first communication device determines the RRM measurement state according to the number of out-of-synchronization (OOS) states within a second time period associated with the RLM result.

[0164] In some embodiments, the RLM result is obtained by the first communications device measuring an RLM reference signal through a main receiver, or the RLM result is obtained by the first communications device measuring an RLM reference signal through a wake-up receiver.

[0165] Optionally, if the RLM result is obtained by the first communication device by measuring the RLM reference signal through the wake-up receiver, the wake-up receiver of the first communication device may send the RLM result to the main receiver of the first communication device.

[0166] It should be noted that RRM measurements are primarily used to monitor UE mobility, enable timely cell selection, and prevent radio link failures. For terminals with relatively fixed locations, such as sensors and fixed access terminals, or for ordinary terminals that maintain a fixed location for extended periods or move only within a limited range, the need for RRM measurements is relatively low. These terminals can refrain from performing RRM measurements for extended periods, including RRM measurements of the serving cell. RRM measurement relaxation is also possible. Completely ceasing RRM measurements is equivalent to a high degree of RRM measurement relaxation.

[0167] Currently, the UE can determine whether it is a stationary or low-mobility terminal based on the following information:

[0168] According to the RRM measurement results, the UE meets the "low mobility" criterion or the "terminal is not located at the cell edge" criterion;

[0169] Evaluate the terminal's mobility based on the terminal's beam changes in the serving cell;

[0170] The terminal determines whether it has the stationary attribute based on the registration information.

[0171] In an embodiment of the present application, the first communication device may determine the RRM measurement state based on the RLM result. The first communication device needs to send and receive data in the serving cell. In order to ensure the normal transmission of data, the first communication device needs to perform radio link monitoring (RLM). Due to the existence of the RLM process, the first communication device can determine that it is in a certain mobility state through the RLM process, and may decide to stop RRM measurement, perform RRM measurement relaxation, or RRM measurement relaxation fallback. For example, in the NR system, a UE in the RRC connection (RRC_CONNECTED) state monitors the downlink radio link quality of the primary cell through an RLM reference signal (RLM Reference Signal, RLM-RS). The measurement result of RLM-RS is used to evaluate the block error rate (BLER) of the hypothetical PDCCH. According to the evaluation result of RLM-RS, when certain conditions are met, a radio link failure (RLF) can be triggered, so that the UE will trigger the RRC connection re-establishment process.

[0172] In an embodiment of the present application, the first communication device may also determine the RRM measurement state based on the IS / OOS state of the radio link obtained by RLM measurement. Specifically, after configuring the RLM-RS, the first communication device measures the RLM-RS, compares the measurement result with the IS / OOS threshold, thereby obtaining the IS / OOS state of the radio link, and periodically reports the evaluation result of the IS / OOS state to the upper layer. If the measurement result of any RLM-RS among all the configured RLM-RSs is higher than the IS threshold, the physical layer reports the IS state to the upper layer; if the measurement results of all the configured RLM-RSs are lower than the OOS threshold, the physical layer reports the OOS state to the upper layer. The first communication device may determine the RRM measurement state based on the number of IS states within a first time period associated with the RLM result, or the first communication device may determine the RRM measurement state based on the number of OOS states within a second time period associated with the RLM result.

[0173] In some embodiments, the first communications device determines the RRM measurement state according to whether the RLM result indicates that RLF has occurred, including:

[0174] When the RLM result indicates that RLF has not occurred, the first communications device determines that the RRM measurement state is a first RRM measurement state; and / or, when the RLM result indicates that RLF has occurred, the first communications device determines that the RRM measurement state is a second RRM measurement state.

[0175] For example, when the RLM result indicates that RLF has not occurred, the RRM measurement may be stopped, or RRM measurement relaxation may be performed; and / or when the RLM result indicates that RLF has occurred, RRM measurement relaxation fallback may be performed, that is, conventional RRM measurement may be performed.

[0176] In some embodiments, the first communications device determines the RRM measurement state according to whether the RLM result indicates that RLF has occurred, including:

[0177] If the RLM result indicates that RLF has not occurred, the first communications device determines that it is in the first mobility state, and if the RLM result indicates that RLF has occurred, the first communications device determines that it is not in the first mobility state;

[0178] When the first communication device is in the first mobility state, the first communication device determines that the RRM measurement state is the first RRM measurement state; and / or, when the first communication device is not in the first mobility state, the first communication device determines that the RRM measurement state is the second RRM measurement state.

[0179] That is, the RLM result can be used to determine the RRM mobility state of the first communication device, such as "low mobility" or "the terminal is not located at the cell edge".

[0180] In some embodiments, the first communications device determines the RRM measurement state according to the number of IS states within a first duration associated with the RLM result, including:

[0181] When the number of IS states within the first time period associated with the RLM result is greater than or equal to a second threshold, the first communications device determines that the RRM measurement state is the first RRM measurement state; and / or, when the number of IS states within the first time period associated with the RLM result is less than the second threshold, the first communications device determines that the RRM measurement state is the second RRM measurement state.

[0182] For example, when the number of IS states within the first time period associated with the RLM result is greater than or equal to a second threshold, the RRM measurement can be stopped, or the RRM measurement relaxation can be performed; and / or, when the number of IS states within the first time period associated with the RLM result is less than the second threshold, the RRM measurement relaxation fallback is performed, that is, regular RRM measurement is performed.

[0183] In some embodiments, the first communications device determines the RRM measurement state according to the number of IS states within a first duration associated with the RLM result, including:

[0184] If the number of IS states within the first duration associated with the RLM result is greater than or equal to a second threshold, the first communications device determines that it is in the first mobility state; and if the number of IS states within the first duration associated with the RLM result is less than the second threshold, the first communications device determines that it is not in the first mobility state.

[0185] When the first communication device is in the first mobility state, the first communication device determines that the RRM measurement state is the first RRM measurement state; and / or, when the first communication device is not in the first mobility state, the first communication device determines that the RRM measurement state is the second RRM measurement state.

[0186] That is, the number of IS states within the first duration associated with the RLM result can be used to determine the RRM mobility state of the first communication device, such as "low mobility" or "the terminal is not located at the cell edge".

[0187] In some embodiments, the first communications device determines the RRM measurement status according to the number of OOS states within a second time period associated with the RLM result, including:

[0188] If the number of OOS states within the second time period associated with the RLM result is less than a third threshold, the first communications device determines that the RRM measurement state is the first RRM measurement state; and / or, if the number of OOS states within the second time period associated with the RLM result is greater than or equal to the third threshold, the first communications device determines that the RRM measurement state is the second RRM measurement state.

[0189] For example, when the number of OOS states within the second time period associated with the RLM result is less than a third threshold, the RRM measurement may be stopped, or the RRM measurement may be relaxed; and / or, when the number of OOS states within the second time period associated with the RLM result is greater than or equal to the third threshold, the RRM measurement relaxation fallback may be performed, that is, regular RRM measurement may be performed.

[0190] In some embodiments, the first communications device determines the RRM measurement status according to the number of OOS states within a second time period associated with the RLM result, including:

[0191] If the number of OOS states within the second time period associated with the RLM result is less than a third threshold, the first communications device determines that it is in the first mobility state; and if the number of OOS states within the second time period associated with the RLM result is greater than or equal to the third threshold, the first communications device determines that it is not in the first mobility state.

[0192] When the first communication device is in the first mobility state, the first communication device determines that the RRM measurement state is the first RRM measurement state; and / or, when the first communication device is not in the first mobility state, the first communication device determines that the RRM measurement state is the second RRM measurement state.

[0193] That is, the number of OOS states within the second time period associated with the RLM result can be used to determine the RRM mobility state of the first communication device, such as "low mobility" or "the terminal is not located at the cell edge".

[0194] In some embodiments, the first duration and / or the second threshold are agreed upon by a protocol, or the first duration and / or the second threshold are configured by a network, or the first duration and / or the second threshold are determined by the first communication device.

[0195] In some embodiments, the second duration and / or the third threshold are agreed upon by a protocol, or the second duration and / or the third threshold are configured by a network, or the second duration and / or the third threshold are determined by the first communication device.

[0196] In some embodiments, as shown in FIG8 , when the first communication device is in the first mobility state, RRM measurement relaxation is performed; and / or, when the first communication device is not in the first mobility state, RRM measurement relaxation fallback is performed, i.e., conventional RRM measurement is performed.

[0197] In some embodiments, when the first communication device determines that the RRM measurement state is the first RRM measurement state, if the first communication device does not detect target control information within a third time period, the first communication device performs RRM measurement; or, if the amount of target control information detected by the first communication device within the third time period is less than a fourth threshold, the first communication device performs RRM measurement. Optionally, the first communication device performing RRM measurement includes: the first communication device performing RRM measurement of the serving cell and / or the neighboring cell.

[0198] That is, when the first communication device does not detect the target control information within the third time period, or when the amount of target control information detected by the first communication device within the third time period is less than a fourth threshold, the RRM measurement state can fall back from the first RRM measurement state (such as the state of stopping RRM measurement, or the relaxed RRM measurement state) to the second RRM measurement state (such as the state of normal RRM measurement).

[0199] Specifically, under certain conditions, a fallback mechanism for relaxing RRM measurements can be triggered. The second communication device can periodically send the target control information carried by the WUR signal. If the wake-up receiver of the first communication device fails to successfully detect the target control information within a predetermined time, it can trigger the main receiver to be turned on for RRM measurement. A threshold for the number of times the first communication device fails to successfully detect the target control information can be set. When the number of times the target control information is not successfully detected reaches or exceeds a certain threshold, the main receiver is triggered to be turned on for RRM measurement.

[0200] In some embodiments, when a first communication device is in a first mobility state, the first communication device determines the mobility state of the first communication device through a WUR signal. Specifically, when performing RRM measurement fallback, the first communication device performs RRM measurements of a serving cell and a neighboring cell through a primary receiver, wherein measurement relaxation is not performed on the RRM measurement of the neighboring cell until the measurement result of the serving cell by the primary receiver of the first communication device meets a "low mobility" criterion or a "terminal is not located at a cell edge" criterion.

[0201] In some embodiments, the third duration and / or the fourth threshold are agreed upon by a protocol, or the third duration and / or the fourth threshold are configured by a network, or the third duration and / or the fourth threshold are determined by the first communication device.

[0202] In some embodiments, when the first communications device is in the first mobility state, the first communications device determines the RRM measurement state based on the first information. That is, when the first communications device is in the first mobility state, the first communications device is triggered to determine the RRM measurement state based on the first information.

[0203] Specifically, the first communication device determines the RRM measurement state based on the WUR signal or RLM result, which can be triggered by the RRM measurement result of the serving cell by the main receiver. For example, when the measurement result of the serving cell by the main receiver meets the "low mobility" criterion or the "terminal is not at the edge of the cell" criterion, the first communication device determines the RRM measurement state based on the WUR signal or RLM result. In this state, the first communication device can perform RRM measurement of the neighboring cell by performing relaxed RRM measurement through the main receiver, increasing the measurement interval, or not perform RRM measurement on the neighboring cell, and only rely on the wake-up receiver to detect the mobility state of the first communication device.

[0204] In some embodiments, the first communications device receives first indication information, wherein the first indication information is used to instruct the first communications device to determine the RRM measurement state according to the first information.

[0205] In some embodiments, the first indication information is carried through downlink signaling, or the first indication information is carried through sidelink signaling.

[0206] Optionally, the downlink signaling may include but is not limited to at least one of the following: Radio Resource Control (RRC) signaling, downlink control information (DCI), system message, broadcast message, media access control layer control element (MAC CE).

[0207] Optionally, the sidelink signaling may include but is not limited to at least one of the following: PC5-RRC signaling, sidelink MAC CE, and sidelink control information (Sidelink Control Information, SCI).

[0208] Therefore, in an embodiment of the present application, the first communication device can determine the RRM measurement status based on the WUR signal or RLM result, thereby reducing the RRM measurement performed by the main receiver of the first communication device on the service cell, thereby reducing the energy consumption of the RRM measurement.

[0209] The above, in combination with Figures 7 to 8, describes in detail an embodiment of the first communication device of the present application. The following, in combination with Figure 9, describes in detail an embodiment of the second communication device of the present application. It should be understood that the embodiment of the second communication device corresponds to the embodiment of the first communication device, and similar descriptions can refer to the embodiment of the first communication device.

[0210] FIG9 is a schematic flowchart of a wireless communication method 300 according to an embodiment of the present application. As shown in FIG9 , the wireless communication method 300 may include at least part of the following contents:

[0211] S310, the second communication device sends first indication information; wherein, the first indication information is used to instruct the first communication device to determine the RRM measurement status according to first information, and the first information is one of the following: WUR signal, RLM result.

[0212] In some embodiments, the first communication device may be a terminal device, such as the terminal device 120 described above in FIG. 1 .

[0213] In some embodiments, the second communication device may be a device that sends a WUR signal, for example, the second communication device is a base station, or the second communication device is a specific network node that sends the WUR signal, or the second communication device is another terminal. For example, a UE (i.e., the second communication device) in a cell that meets the criterion of "the terminal is not located at the edge of the cell" sends a WUR signal, and the WUR signal has a certain coverage range. When the target UE (i.e., the first communication device) detects the WUR signal, the WUR signal reflects information about a specific mobility state, and the target UE (i.e., the first communication device) determines that a certain mobility state is met.

[0214] In an embodiment of the present application, the first communication device may determine the RRM measurement state based on the WUR signal or the RLM result. Optionally, the first communication device may determine whether to perform relaxed RRM measurement based on the WUR signal or the RLM result, or the first communication device may determine whether to perform RRM measurement based on the WUR signal or the RLM result; wherein the RRM measurement may be an RRM measurement of a serving cell or an RRM measurement of a neighboring cell.

[0215] That is, in the embodiment of the present application, the primary receiver of the first communication device does not need to be periodically turned on to perform RRM measurements, thereby reducing the energy consumption of RRM measurements. In other words, the first communication device turns on the primary receiver to perform RRM measurements of the serving cell based on the WUR signal or RLM result, rather than periodically.

[0216] In the embodiment of the present application, relaxed RRM measurement may refer to: increasing the measurement interval of the RRM measurement, or reducing the measurement frequency of the RRM measurement, or similar expressions, which is not limited in the present application.

[0217] In some embodiments, the RRM measurement state includes a first RRM measurement state and a second RRM measurement state.

[0218] In some embodiments, in a first RRM measurement state, the first communications device stops performing RRM measurements, or the first communications device performs relaxed RRM measurements; and / or, in a second RRM measurement state, the first communications device performs RRM measurements, and the RRM measurements performed by the first communications device are not relaxed. That is, in the second RRM measurement state, the first communications device performs normal RRM measurements, or the first communications device performs conventional RRM measurements. Optionally, the RRM measurements are RRM measurements for a serving cell, or the RRM measurements are RRM measurements for a neighboring cell. Optionally, the RRM measurements are performed by a primary receiver of the first communications device, or the RRM measurements are performed by a wake-up receiver of the first communications device.

[0219] In some embodiments, in a first RRM measurement state, the first communications device determines the mobility state of the first communications device via a WUR signal. That is, in the first RRM measurement state, the first communications device can determine the mobility state of the first communications device via the WUR signal without performing RRM measurements. Optionally, after determining the mobility state of the first communications device, the wake-up receiver of the first communications device can report the mobility state of the first communications device to the primary receiver of the first communications device, thereby enabling the primary receiver of the first communications device to determine that RRM measurements do not need to be performed.

[0220] In some embodiments, in the second RRM measurement state, the first communications device determines the mobility state of the first communications device by measuring a reference signal. That is, in the second RRM measurement state, the first communications device may determine the mobility state of the first communications device by performing regular RRM measurements.

[0221] In some embodiments, in the second RRM measurement state, the first communication device determines the mobility state of the first communication device via the WUR signal. That is, in the second RRM measurement state, the first communication device can determine the mobility state of the first communication device via the WUR signal without performing RRM measurements. Optionally, after determining the mobility state of the first communication device, the wake-up receiver of the first communication device can report the mobility state of the first communication device to the primary receiver of the first communication device, thereby allowing the primary receiver of the first communication device to determine that RRM measurements do not need to be performed.

[0222] In some embodiments, in the first RRM measurement state, when it is determined that the first communication device is not in the first mobility state, the RRM measurement state is adjusted from the first RRM measurement state to the second RRM measurement state. That is, when the first communication device is not in the first mobility state, the RRM measurement state of the first communication device can fall back from the first RRM measurement state (such as the state of stopping performing RRM measurement or the relaxed RRM measurement state) to the second RRM measurement state (such as the conventional RRM measurement state). Thus, when the mobility state of the first communication device changes, it can fall back to the normal RRM measurement process in time to ensure the mobility performance of the first communication device. Optionally, after determining that the first communication device is not in the first mobility state, the wake-up receiver of the first communication device can report the mobility state of the first communication device to the main receiver of the first communication device, so that the main receiver of the first communication device can determine to fall back to the conventional RRM measurement state.

[0223] In some embodiments, in the first RRM measurement state, when it is determined that the first communications device is in the first mobility state, the RRM measurement state is maintained in the first RRM measurement state. That is, when the first communications device is in the first mobility state, the first communications device maintains the first RRM measurement state (e.g., a state in which RRM measurement is stopped or a relaxed RRM measurement state), thereby reducing energy consumption of RRM measurement.

[0224] In some embodiments, in the second RRM measurement state, when it is determined that the first communication device is in the first mobility state, the RRM measurement state is adjusted from the second RRM measurement state to the first RRM measurement state. That is, when the first communication device is in the first mobility state, the RRM measurement state of the first communication device can be adjusted from the second RRM measurement state (such as the regular RRM measurement state) to the first RRM measurement state (such as the state of stopping performing RRM measurement or the relaxed RRM measurement state), thereby reducing the energy consumption of RRM measurement. Optionally, after determining that the first communication device is in the first mobility state, the wake-up receiver of the first communication device can report the mobility state of the first communication device to the primary receiver of the first communication device, so that the primary receiver of the first communication device can determine to stop performing the regular RRM measurement state.

[0225] In some embodiments, in the second RRM measurement state, when it is determined that the first communications device is in the first mobility state, the RRM measurement state is maintained in the second RRM measurement state. That is, when the first communications device is not in the first mobility state, the first communications device maintains the second RRM measurement state (e.g., a conventional RRM measurement state) to ensure the mobility performance of the first communications device. Optionally, after determining that the first communications device is not in the first mobility state, the wake-up receiver of the first communications device may report the mobility state of the first communications device to the primary receiver of the first communications device, so that the primary receiver of the first communications device may determine to maintain the conventional RRM measurement state.

[0226] In some embodiments, the first mobility state is a low mobility state. That is, when the first communication device is in the first mobility state, it can be considered that the first communication device meets the "low mobility" criterion. For the description of the "low mobility" criterion, reference can be made to the above-mentioned related description and will not be repeated here.

[0227] In some embodiments, the first mobility state is a state in which the first communication device is not located at a cell edge. That is, when the first communication device is in the first mobility state, it can be considered that the first communication device meets the "terminal is not located at a cell edge" criterion. For a description of the "terminal is not located at a cell edge" criterion, reference can be made to the above-mentioned related description and will not be repeated here.

[0228] In some embodiments, when the first information is a WUR signal, whether target control information is detected in the WUR signal is used by the first communication device to determine the RRM measurement state, or the measurement result of the WUR signal is used by the first communication device to determine the RRM measurement state.
