Description

Communication method and communication device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on April 3, 2024, with application number 202410405464.4 and application name “A Communication Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and a communication device. Background Art

[0003] To achieve lower terminal power consumption, an ultra-low power wake-up signal (LP-WUS) mechanism is currently proposed. In hardware implementation, the terminal's receiving circuit is divided into two parts: the main receiver / main link (MR) and the low power wake-up receiver (LR / LP-WUR). When there is no business data transmission on the MR, it can enter the shutdown state to significantly reduce the power consumption of the terminal, while turning on the LP-WUR to monitor the wake-up signal (WUS). When the LP-WUR receives the wake-up signal, it will wake up the MR for data / business transmission.

[0004] Considering that using MR to measure the service cell will have a significant impact on the energy consumption of the terminal, the terminal can perform signal quality measurement of the service cell and more precise time-frequency synchronization by receiving a low power reference signal (LP-SS) on the LP-WUR. According to the standard's evaluation of LP-WUS, the link performance of LP-WUS may be worse than that of traditional physical channels. For terminals in a non-connected state, the signal quality measurement results of the service cell on the MR or LP-WUR can be used to determine whether the terminal needs to activate / deactivate the use of LP-WUS. However, when the terminal is at the boundary of the LP-WUS coverage, it may generate measurement ping-pong behavior due to its own mobility. That is, the terminal may turn off the LP-WUR and wake up the MR to enter the working state based on the measurement results of the LP-WUR, and then turn off the MR based on the measurement results of the MR and switch back to the LP-WUR to monitor the LP-WUS. The LP-WUR and MR will frequently switch between the two states of the off state and the working state. In this way, considering the high conversion energy consumption of the terminal switching from LP-WUR to MR to enter the working state, the terminal's ping-pong behavior of activating / deactivating LP-WUS will introduce a large power consumption overhead, reducing the energy saving gain brought by using LP-WUS. Summary of the Invention

[0005] The embodiments of the present application provide a communication method and a communication device, which can reduce the power consumption overhead of terminal equipment and improve the energy saving gain brought by using LP-WUS.

[0006] In a first aspect, a communication method is provided. Optionally, the execution subject of the method may be a terminal device, or a component or device in the terminal device (such as a processor, chip, or chip system, etc.), or a logic module or software that can realize all or part of the terminal device functions. The terminal device includes a main receiver MR and a low-power wake-up receiver LP-WUR. The method includes: measuring the signal quality of the serving cell through MR; if the signal quality of the serving cell measured by MR meets the first activation condition of LP-WUR, measuring the signal quality of the serving cell through LP-WUR within a first time period; and determining whether the signal quality of the serving cell measured by LP-WUR meets the second activation condition of LP-WUR.

[0007] That is to say, when MR determines that LP-WUR is turned on, it continues to determine whether the measurement results of the service cell meet the activation conditions of LP-WUR within the first time period when LP-WUR is turned on. In this way, it can be further determined within the first time period whether to keep LP-WUR working or MR is in working state. Compared with the existing terminal equipment supporting LP-WUS at the edge of LP-WUS coverage, if MR is directly turned off when switching to LP-WUR work, the problem of frequent and unnecessary switching due to the ping-pong problem of measurement caused by its own high mobility may be caused. The present application is equivalent to continuing to determine whether the activation conditions of LP-WUR are met according to the first time period extended when LP-WUR is turned on, and then deciding whether to keep LP-WUR working or return to MR work based on the judgment result of the extended time period, which can avoid the problem of frequent and unnecessary switching due to the ping-pong problem of measurement caused by its own high mobility, reduce the power consumption overhead of the terminal equipment, and improve the energy-saving gain of LP-WUS use.

[0008] In one possible design, the first activation condition includes: within a second time period, the signal quality of the serving cell measured by the MR is greater than or equal to a first preset threshold. That is, if the signal quality of the serving cell measured by the MR is high, the signal quality on the LP-WUR can be considered high. If there is no data or service transmission on the MR, the LP-WUR can be enabled to monitor the wake-up signal to reduce power consumption overhead of the terminal device.

[0009] In one possible design, the second activation condition includes: within the first time period, a signal quality of the serving cell measured by the LP-WUR is greater than or equal to a second preset threshold. If the signal quality of the serving cell measured by the LP-WUR is high, it can be understood that the LP-WUR is within the coverage of the LP-WUS. The LP-WUR can continue to operate normally, thereby improving the energy saving gain of the LP-WUS.

[0010] In one possible design, during a first time period, the MR is in a first state, and the power consumption of the terminal device when the MR is in the first state is greater than the power consumption of the terminal device when the MR is in the off state. This can be understood as, for example, during the first time period when the MR is powered on by the LP-WUR, the MR's first state can be a normal operating state or a light sleep state that is lighter than an ultra-deep sleep state. In this way, if the LP-WUR determines that the MR is continuing to operate during the first time period, the MR can continue to operate in a normal operating state or transition from an abnormal operating state to a normal operating state, thereby saving the power consumption of the MR switching to a normal operating state.

[0011] In one possible design, the first state is the MR's normal operating state. Specifically, the MR maintains normal operating mode during the first period of LP-WUR normal operation, monitoring paging signals and measuring the signal quality of the serving cell. Furthermore, while the LP-WUR participates in determining the second activation condition during the first period, the MR can also participate in determining whether to switch between the MR and LP-WUR using the first activation condition during the first period, thereby improving the accuracy of the handover determination.

[0012] In one possible design, the first state is the first sleep state of the MR, and the first sleep state satisfies the following conditions: the power consumption of waking up the MR in the first sleep state is less than the power consumption of waking up the MR in the second sleep state; the first sleep state also satisfies the following conditions: the average power consumption of the communication module of the terminal device in the first sleep state is greater than the average power consumption of the communication module in the second sleep state, and / or the minimum power consumption of the communication module in the first sleep state is greater than the maximum power consumption of the communication module in the second sleep state. The first sleep state can be understood as an abnormal operating state of the MR. For example, if the second sleep state is an ultra-deep sleep state, the first sleep state can be one of deep sleep, light sleep, or light-light sleep. Thus, when it is determined to switch to MR operation within the first time period, the power consumption of the MR switching from one of the deep sleep, light sleep, or light-light sleep states to normal operation is relatively low, thereby saving power consumption of the terminal device.

[0013] In one possible design, the method further includes: if the signal quality of the serving cell measured by the LP-WUR satisfies a second activation condition, shutting down the MR after the first time period. That is, regardless of whether the MR is in a normal operating state or a first sleep state during the first time period, if the LP-WUR determines that the second activation condition is satisfied during the first time period, indicating that the LP-WUR is within the coverage of the LP-WUS, the MR may be shut down during the first time period to achieve energy savings from the use of the LP-WUS.

[0014] In one possible design, the method further includes: if the signal quality of the serving cell measured by the LP-WUR satisfies the second activation condition, and the signal quality of the serving cell measured by the MR during the first time period satisfies the first activation condition, deactivating the MR after the first time period. That is, if the MR is in a normal operating state during the first time period, whether to deactivate the MR may be determined by referring to both the MR's serving cell measurement result and the LP-WUR's serving cell measurement result, thereby improving the accuracy of the determination result.

[0015] In one possible design, the method further includes shutting down the LP-WUR if the signal quality of the serving cell measured by the LP-WUR determines that the second activation condition of the LP-WUR is not satisfied. That is, if the LP-WUR determines within the first time period that the second activation condition of the LP-WUR is still not satisfied, the LP-WUR may be outside the coverage of the LP-WUS and is not suitable for normal operation of the LP-WUR. Therefore, the LP-WUR may be shut down while the MR continues to operate normally.

[0016] In one possible design, the method further includes: if the signal quality of the serving cell measured by the MR during the first time period does not meet the first activation condition, shutting down the LP-WUR. If the MR measurement result does not meet the first activation condition, it can be considered that the signal quality on the MR is poor, and accordingly, the signal quality on the LP-WUR is also poor, and the LP-WUR may be outside the coverage range of the LP-WUS. Therefore, the LP-WUR can be shut down, and the MR can maintain normal operation.

[0017] In one possible design, the method further includes: if a wake-up signal from the LP-WUR and / or a paging signal from the MR is received within the first time period, shutting down the LP-WUR. That is, during the first time period during which the LP-WUR continues to perform determination, if a wake-up signal is received or the MR receives a paging signal, it is considered that the MR is about to enter a normal operating state, such as data / service transmission. Therefore, the result of the LP-WUR's continued determination should be shutting down the LP-WUR and maintaining the MR in a normal operating state, thereby ensuring data / service transmission performance of the terminal device.

[0018] In one possible design, the method further includes: if the signal quality of the service cell measured by the LP-WUR does not meet the second activation condition, the LP-WUR is turned off, and the MR in the first state is awakened to enter a normal working state. If the MR is in the first sleep state during the first time period, once the LP-WUR determines that the second activation condition is not met during the first time period, the LP-WUR may no longer be within the coverage of the LP-WUS. The LP-WUR can be turned off, and the MR is switched from the first sleep state to the normal working state. Compared to directly turning off the MR during normal operation of the LP-WUR, the present application reduces the power consumption of the conversion of the MR from the first sleep state to the normal working state.

[0019] In one possible design, the method further includes: if a wake-up signal from the LP-WUR is received within the first time period, shutting down the LP-WUR and waking up the MR in the first state to enter a normal operating state. In this way, if there are ping-pong fluctuations in measurement results during the first time period, indicating that continued operation of the LP-WUR is no longer appropriate, the terminal device can directly shut down the LP-WUR and return the MR to its normal operating state, thereby avoiding the high power consumption associated with directly shutting down and then waking up the MR during the first time period.

[0020] In one possible design, if the signal quality of the serving cell measured by the MR meets the first activation condition of the LP-WUR, then measuring the signal quality of the serving cell by the low-power wake-up receiver LP-WUR within the first time period includes: if the signal quality of the serving cell measured by the MR meets the first activation condition of the LP-WUR and meets at least one of the first conditions, then measuring the signal quality of the serving cell by the LP-WUR within the first time period; wherein the first condition includes: the signal quality of the serving cell or the neighboring cell measured by the MR or LP-WUR within the third time period is less than or equal to a third preset threshold; or, the change in the signal quality of the serving cell or the neighboring cell measured by the MR or LP-WUR within the fourth time period is greater than or equal to a fourth preset threshold. That is, the method of the present application can meet terminal devices under specific conditions, such as when the terminal device is at the cell edge and / or in high mobility, and then determine whether to turn off the LP-WUR or the MR based on the above-mentioned first time period and the second activation condition. In this way, the delay that may be caused to terminal devices using LP-WUS in the center of the serving cell or with low mobility can also be avoided.

[0021] In a second aspect, a communication method is provided. Optionally, the execution subject of the method may be a terminal device, or a component or device in the terminal device (such as a processor, chip, or chip system, etc.), or a logic module or software that can realize all or part of the terminal device functions. The terminal device includes a main receiver MR and a low-power wake-up receiver LP-WUR. The method includes: monitoring a wake-up signal on the LP-WUR; if a wake-up signal of the LP-WUR is received within a first time period, or the time interval from the last time the wake-up signal of the LP-WUR is received is less than or equal to a first time threshold, then keeping the LP-WUR in a normal working state.

[0022] In this way, if LP-WUR can receive the wake-up signal within the first time end, or the time interval since the last time the wake-up signal was received is small, it can be considered that LP-WUR is still within the coverage range of the wake-up signal (LP-WUS), so LP-WUR can continue to be kept in normal working state.

[0023] Compared with the current standard design of LP-WUS deactivation conditions, which is determined only based on the measurement results of the serving cell, this application proposes a decision scheme for LP-WUS deactivation conditions based on wake-up signal reception and LP-WUR measurement results, which can avoid unnecessary switching caused by misjudgment due to inaccurate measurements of terminal devices at the edge of LP-WUS coverage.

[0024] In one possible design, the method further includes: if at least one of the second conditions is met within the first time period, turning off the LP-WUR or keeping the LP-WUR in a normal working state. That is, the present application can determine whether to turn off the LP-WUR through the second condition. The second condition includes: no wake-up signal from the LP-WUR is received; or, the time interval from the last time the wake-up signal from the LP-WUR is received is greater than the first time threshold. That is, if the LP-WUR does not receive a wake-up signal within the first time period, or the time interval from the last time the wake-up signal from the LP-WUR is received is long, then the LP-WUR may be outside the coverage of the LP-WUS, or there may be no LP-WUS to receive, and further judgment is needed on whether to turn off the LP-WUR.

[0025] In one possible design, shutting down the LP-WUR includes: if at least one of the second conditions is met within a first time period, and the signal quality of the serving cell measured by the LP-WUR meets the LP-WUR deactivation condition, shutting down the LP-WUR and waking up the MR to enter a normal operating state. Thus, if the LP-WUR does not receive a wake-up signal within the first time period, or if the time interval since the last receipt of the LP-WUR wake-up signal is long, and the signal quality of the serving cell measured by the LP-WUR meets the LP-WUR deactivation condition, the LP-WUR may be deemed to be outside the coverage of the LP-WUS. That is, determining whether to deactivate the LP-WUR based on both the wake-up signal and the measurement result can avoid unnecessary handover issues caused by unreliable LP-WUR measurement results.

[0026] In one possible design, shutting down the LP-WUR includes: if at least one of the second conditions is met within a first time period, the signal quality of the serving cell measured by the LP-WUR does not meet the LP-WUR deactivation conditions, and no LP-WUR wake-up signal is received within a second time period, shutting down the LP-WUR after the second time period and waking up the MR to enter normal operation; the second time period is after the first time period. Thus, if the LP-WUR does not receive a wake-up signal within the first time period, or if the interval since the last LP-WUR wake-up signal was received is long, but the LP-WUR measurement result does not meet the deactivation conditions, it is possible that the LP-WUR measurement result is too high, making the measurement result unreliable. In this case, the LP-WUR can continue to determine whether a wake-up signal is received within the second time period. If no LP-WUR wake-up signal is received within the second time period, the previous measurement result can be considered inaccurate, and the MR can switch to normal operation. This condition of determining whether the wake-up signal is received and whether to deactivate the LP-WUR based on the measurement result can avoid unnecessary handovers caused by misjudgments due to insufficient LP-WUR measurement accuracy.

[0027] In one possible design, shutting down the LP-WUR includes: if at least one of the second conditions is met during a first time period, and the signal quality of the serving cell measured by the LP-WUR does not meet the LP-WUR deactivation conditions, but during a second time period, the signal quality of the serving cell measured by the LP-WUR meets the LP-WUR deactivation conditions, shutting down the LP-WUR and waking up the MR to enter normal operation; the second time period is after the first time period. That is, if the LP-WUR does not receive a wake-up signal during the first time period, or if the interval since the last time the LP-WUR wake-up signal was received is long, the LP-WUR measurement results during the first time period do not meet the deactivation conditions. This may indicate that the LP-WUR measurement results are too high, making the measurement results unreliable. In this case, further determination can be made during the second time period. If the signal measurement results obtained during the second time period meet the deactivation conditions, the measurement results of the first time period can be considered inaccurate, and the MR can be switched to normal operation. This conditional determination of whether the wake-up signal is received and whether the measurement results determine whether to deactivate the LP-WUR can avoid unnecessary handovers caused by misjudgments due to insufficient LP-WUR measurement accuracy.

[0028] In one possible design, keeping the LP-WUR in a normal working state includes: if a wake-up signal from the LP-WUR is received within a second time period, keeping the LP-WUR in a normal working state; wherein the second time period is after the first time period. That is, if the LP-WUR does not receive a wake-up signal within the first time period, or the time interval from the last time the wake-up signal from the LP-WUR is received is long, the measurement result of the LP-WUR within the first time period does not meet the deactivation condition, it is possible that the result of the LP-WUR is too high, and there is a problem of unreliable measurement results. At this time, the judgment can continue within the second time period. If a wake-up signal from the LP-WUR is received within the second time period, it can be considered that the measurement result within the first time period is accurate, and the LP-WUR is still within the coverage range of the LP-WUS. The LP-WUR can continue to be kept in a normal working state to avoid unnecessary switching.

[0029] In one possible design, if a wake-up signal from the LP-WUR is received within a first time period, or the time interval from the last time the wake-up signal from the LP-WUR is received is less than or equal to a first time threshold, then maintaining the LP-WUR in a normal working state includes: if a wake-up signal from the LP-WUR is received within the first time period, or the time interval from the last time the wake-up signal from the LP-WUR is received is less than or equal to the first time threshold, and at least one of the first conditions is satisfied, then maintaining the LP-WUR in a normal working state includes: the signal quality of the serving cell or neighboring cell measured by the MR or LP-WUR within a third time period is less than or equal to a third preset threshold; or the change in the signal quality of the serving cell or neighboring cell measured by the MR or LP-WUR within a fourth time period is greater than or equal to a fourth preset threshold. That is, the present application can perform the above-mentioned determination of whether to switch to the LP-WUR based on the measurement results of the wake-up signal and the serving cell on terminal devices that meet specific conditions, and can perform the above-mentioned determination on whether to switch to the LP-WUR based on the measurement results of the wake-up signal and the serving cell. It can be performed on terminal devices at the coverage edge of the LP-WUS and / or on terminal devices in a high-speed mobile state to avoid the delay that may be caused by terminal devices using the LP-WUS in the cell center or with low mobility.

[0030] In one possible design, the deactivation conditions of LP-WUR include: a first time period T detect Within, the signal quality of the service cell measured by LP-WUR is less than the fifth preset threshold.

[0031] According to a third aspect, a communication device is provided. Optionally, the device may be a terminal device, or a component or device in the terminal device (such as a processor, a chip, or a chip system, etc.), or a logic module or software that can realize all or part of the functions of the terminal device. The terminal device includes a main receiver MR and a low-power wake-up receiver LP-WUR. The device includes: a measuring unit for measuring the signal quality of the service cell through MR; the measuring unit is further used to measure the signal quality of the service cell through LP-WUR within a first time period if the signal quality of the service cell measured by MR meets the first activation condition of LP-WUR; and a determination unit for determining whether the signal quality of the service cell measured by LP-WUR meets the second activation condition of LP-WUR.

[0069] For ease of understanding, some examples of concepts related to the embodiments of the present application are provided for reference as follows.

[0070] Ultra-low power wake-up signal (LP-WUS): To achieve lower terminal power consumption, 3GPP Release 19 proposed the LP-WUS mechanism. Figure 1 shows a schematic diagram of the LP-WUS mechanism. In hardware, the terminal's receiving circuitry is divided into two parts: the main receiver / main circuit / main link (MR) and the low power receiver (LP-WUR / LR). The MR is used to normally receive data / service transmissions, while the LP-WUR serves as a dedicated auxiliary receiver for wake-up signals, detecting and processing wake-up signals. The energy-saving logic of the LP-WUS mechanism is that when the MR is not transmitting data / services, it can enter a shutdown or sleep state to significantly reduce the terminal's standby power consumption, while the LP-WUR is turned on to monitor for wake-up signals. When the wake-up signal received by the LP-WUR indicates that the MR should be woken up, it wakes up the MR for data / service transmission. Currently, the LP-WUR can perform / execute other operations besides monitoring paging.

[0071] Non-connected LP-WUS sleep state: Currently, the standard introduces a new operating state for MR in the LP-WUS state (RRC_IDLE) or RRC_INACTIVE (RRC_INACTIVE) of the radio resource control (RRC) idle state, called the ultra-deep sleep state. Compared to other current sleep states, this ultra-deep sleep state significantly reduces energy consumption. For details, see Table 1, which shows various operating states and their relative energy consumption compared to deep sleep.

[0072] Table 1

[0073] For a terminal in MR ultra-deep sleep mode using LP-WUR to receive LP-WUS, the standard provides evaluation results showing that the transition power consumption from LP-WUR back to MR (i.e., MR wakeup) can reach 15,000 units, with a transition latency of up to 400ms. Compared to the 450 units of transition power consumption and 20ms latency in deep sleep mode evaluated in the standard, it can be seen that waking up MR from LP-WUR incurs significant transition power consumption.

[0074] Radio resource management (RRM) measurements enable a terminal to monitor the communication quality of its serving cell and / or neighboring cells (i.e., non-serving cells) in real time. Mobility management operations such as handover and cell selection / reselection rely on RRM measurements, making them fundamental to mobility management.

[0075] When the terminal is in the RRC idle state or the RRC inactive state, the network can broadcast the measurement configuration. The terminal performs measurements according to the broadcast measurement configuration and uses the measurement results to perform operations such as cell selection / reselection without reporting the measurement results to the network. The network side (base station) can provide the measurement configuration to the terminal by broadcasting. For example, the measurement configuration is sent through system information (SI), specifically, the measurement configuration can be sent in SIB2, SIB3, SIB4 or SIB5 in the system information. The measurement configuration may include frequency information, measurement time window configuration, and threshold and offset parameters.

[0076] Based on the relationship between the measurement frequency and the serving cell frequency, measurements can be divided into intra-frequency measurement, inter-frequency measurement, and inter-RAT measurement. Inter-system measurement refers to measurements on systems other than the 5G NR system (for example, measurements on 2G / 3G / 4G (LTE) systems). Intra-frequency and inter-frequency measurements are intra-RAT measurements.

[0077] In 5G NR systems, there are two types of reference signals for frequency measurement: synchronization signal / physical broadcast channel block (SS / PBCH Block, SSB) and channel state information reference signal (CSI-RS). Depending on the type of reference signal at the frequency, measurements can be divided into SSB-based measurements and CSI-RS-based measurements. Measurements in the connected state can be based on either SSB or CSI-RS, while measurements in the idle / inactive state are based only on SSB. Therefore, combining the classification methods of the above two measurement types, measurements can be specifically divided into: SSB-based intra-frequency measurements, SSB-based inter-frequency measurements, CSI-RS-based intra-frequency measurements, CSI-RS-based inter-frequency measurements, and inter-system measurements.

[0078] The present application relates to measurements in the idle / inactive state. Taking the NR system as an example, in the SSB-based measurement in the idle / inactive state, if the SSB center frequency of a certain measurement frequency point is the same as the SSB center frequency of the serving cell, and the subcarrier spacing SCS of the SSBs of the two is also the same, then the frequency point measurement is a same-frequency measurement; otherwise, that is, one of the center frequencies of the SSBs and the subcarrier spacing of the SSBs is different, then the frequency point measurement is a different-frequency measurement. Of course, the present application is not limited to SSB-based measurements in the idle / inactive state, and can also be measurements based on other types of reference signals in the idle / inactive state.

[0079] The quantity measured by the terminal device, that is, the measured reference signal power value / quality, can be divided into three types, each of which can be based on SSB or CSI-RS. These three types include:

[0080] Reference signal received power (RSRP) is defined as the linear average of the power of resource elements (REs) carrying reference signals within the measurement bandwidth under consideration.

[0081] Reference signal received quality (RSRQ): Defined as the ratio, RSRQ = (N * RSRP) / NR carrier RSSI. The NR carrier received signal strength indicator (RSSI) is the linear average of the total received power observed by the terminal device over N resource blocks (RBs), including sources such as co-channel serving and non-serving cells, adjacent channel interference, and thermal noise. N is the number of resource blocks (RBs) in the NR carrier RSSI measurement. RSRP can be either SS-RSRP or CSI-RSRP.

[0082] Signal-to-noise and interference ratio (SINR): It is defined as the linear average power of resource elements (REs) carrying the reference signal divided by the linear average power of the noise and interference on these REs within the measurement bandwidth under consideration, that is, SINR = RSRP / (Noise+Interference).

[0083] LP-WUS mobility measurement: To ensure that a terminal device in RRC idle state or RRC inactive state resides in a suitable cell, the terminal device needs to perform mobility measurement. Mobility RRM measurements include serving cell measurements and neighboring cell measurements. For most terminals, serving cell measurements need to be performed frequently in a network without coverage blind spots, so the measurement behavior will also have the greatest impact on terminal energy consumption. For terminals using LP-WUS, infrequently starting MR for neighboring cell measurements may not have a significant impact on terminal energy consumption. However, according to the evaluation results, using MR for serving cell measurements will have a significant impact on terminal energy consumption, reducing the LP-WUS energy saving gain. In order to achieve terminal power saving gains through LP-WUS / WUR, when the terminal device is using LP-WUS, it can be considered to offload the serving cell measurement to LP-WUR.

[0084] Due to the low-power design structure of the auxiliary receiver LP-WUR, it may not be able to receive reference signals (such as SSB) in the NR system. The standard introduces a special reference signal for LP-WUR to receive, such as the low power-synchronization signal (LP-SS). The UE can measure the signal quality of the serving cell and synchronize time and frequency by receiving the LP-SS on the LP-WUR.

[0085] For LP-WUR's signal quality measurement of the serving cell based on LP-SS, the following metrics can be used for further research and evaluation (including feasibility, complexity, power consumption, etc.):

[0086] LP-RSSI or Energy Detection: The linear average of the total received power over the RSSI resource.

[0087] LP-RSRP: The linear average of the received power of a reference signal or a signal portion of a resource.

[0088] LP-SINR: LP-RSRP / interference noise power.

[0089] LP-RSRQ: (N*LP-RSRP) / LP-RSSI, where N is the resource size difference factor used to evaluate LP-RSRP and LP-RSSI.

[0090] The embodiments of the present application can be applied to wireless communication systems such as the fifth generation mobile communication networks (5G), the sixth generation mobile communication networks (6G), satellite communication, and possible future communication technologies, including but not limited to narrowband Internet of Things (NB-IoT), global system for mobile communications (GSM), enhanced data rate for GSM evolution (EDGE), wideband code division multiple access (WCDMA), code division multiple access 2000 (CDMA2000), time division-synchronization code division multiple access (TD-SCDMA), long term evolution (LTE), and three major application scenarios of 5G mobile communication systems: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and enhanced machine-type communications (EMTC). communication, eMTC), 6G mobile communication systems and possible future mobile communication systems.

[0091] For example, in a 5G new radio (NR) system scenario, a schematic diagram of a 5G NR system architecture is shown in Figure 2. The 5G NR system includes a 5G core network (5G core network, 5GC), a 5G radio access network / next generation radio access network (NG-RAN), and terminal devices.

[0092] 5GC mainly includes the access and mobility management function (AMF) network element and the user plane function (UPF) network element. Its main functions include mobility management such as non-access stratum (NAS) signaling security, access layer security control, access authentication, access authorization, and registration area management.

[0093] NG-RAN primarily comprises RAN nodes, including 5G base stations (gNodeBs, gNBs) and ng-eNBs (4G base stations connected to 5G). A gNB is a device deployed in the radio access network that meets 5G standards and provides wireless communication capabilities for terminals. gNBs can include various forms of macro base stations, micro base stations (also known as small cells), relay stations, access points, wearable devices, and in-vehicle equipment. A gNB can also function as a transmission and reception point (TRP) or a transmission measurement function (TMF).

[0094] In another application scenario, multiple RAN nodes can collaborate to help terminals achieve wireless access, with different RAN nodes implementing portions of the base station's functions. For example, a RAN node can be a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The CU implements the base station's radio resource control protocol and packet data convergence protocol (PDCP) functions, as well as the service data adaptation protocol (SDAP) functions. The DU implements the base station's radio link control layer and medium access control (MAC) layer functions, as well as some or all of the physical layer functions. For detailed descriptions of each of the above protocol layers, please refer to the relevant 3GPP technical specifications. The RU can be used to implement the transmission and reception of radio frequency signals. The CU and DU can be two independent RAN nodes, or they can be integrated into the same RAN node, such as in a baseband unit (BBU). The RU can be included in radio frequency equipment, such as a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0095] In different systems, RAN nodes may have different names. For example, in an O-RAN system, a CU may be called an open CU (O-CU), a DU may be called an open DU (O-DU), and a RU may be called an open RU (O-RU). The RAN node in the embodiments of the present application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. For example, the RAN node may be a server loaded with the corresponding software module. The embodiments of the present application do not limit the specific technology and specific device form adopted by the RAN node. For ease of description, the following description takes a base station as an example of a RAN node.

[0096] A terminal device is a device with wireless transceiver capabilities that can send signals to a base station or receive signals from a base station. A terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, wearable device, vehicle, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of this application do not limit the specific technology and specific device form adopted by the terminal.

[0097] The base station / 5GC can send information to the terminal device, such as paging information and terminal device group-related information. The terminal device can also send information to the base station / 5GC, such as terminal device capability information and terminal device feature information.

[0098] In the network architecture of the present application, according to the standard evaluation of the LP-WUS of the terminal device, the LP-WUS link performance may be worse than that of the traditional physical channel (for example, PDCCH), that is, the LP-WUS is partially covered in the cell. In the case of partial coverage, the MR of the terminal device can only remain in the ultra-deep sleep state when the terminal device is within the coverage of the LP-WUS. When the terminal device moves out of the coverage of the LP-WUS, the network cannot wake up the MR of the terminal device through the LP-WUS, and the terminal device needs to independently determine whether it has moved in / out of the LP-WUS coverage, so that it can fall back to MR monitoring normal paging when the coverage of the LP-WUS is insufficient.

[0099] The method currently considered in the standard is to define a network pre-configured quality threshold to determine the coverage of LP-WUS. Specifically, the measurement results of the serving cell on MR / LP-WUR can be used to determine whether it is necessary to activate / deactivate the use of LP-WUS. Specifically, a possible design is that when the measurement result based on the reference signal (such as SSB or special reference signal (LP-SS)) on LP-WUR is lower than the decision threshold, the MR of the terminal device wakes up (that is, exits the ultra-deep sleep power state) and the LR can stop monitoring LP-WUS; when the measurement result based on the reference signal (such as SSB) on MR is higher than the decision threshold, the terminal device can turn off MR and turn on LP-WUR to monitor LP-WUS.

[0100] However, for terminal devices in a non-connected state, if the above-mentioned LP-WUS activation / deactivation conditions are applied to determine the switching of MR / LP-WUR, when the terminal device is at the LP-WUS coverage boundary, measurement ping-pong behavior may occur due to its own mobility.

[0101] Specifically, Figure 3 shows a schematic diagram of determining whether to activate / deactivate LP-WUS based on the measurement results of the serving cell on the MR / LP-WUR. The horizontal axis represents time T, and the vertical axis represents the measurement results of the serving cell on the MR / LP-WUR. If the terminal device happens to re-enter LP-WUS coverage at time T1, the MR performs a measurement and the measurement result is greater than the LP-WUS activation threshold, meeting the LP-WUS activation condition. The terminal device will then activate the LP-WUR to monitor the LP-WUS. If at time T2, the terminal device using LP-WUR to monitor LP-WUS exits LP-WUS coverage, and the measurement result on LP-WUR is less than the deactivation threshold of LP-WUS, the LP-WUS deactivation condition is met, the terminal device will stop monitoring LP-WUS and turn off LP-WUR and wake up MR at time T2; if at time T3, the terminal device happens to re-enter LP-WUS coverage, MR performs measurement and the measurement result will be greater than the activation threshold of LP-WUS, meeting the LP-WUS activation condition, and the terminal device will re-turn on LP-WUR to monitor LP-WUS.

[0102] In this way, considering the high conversion energy consumption of terminal devices switching from LP-WUR to MR, the ping-pong behavior of activating / deactivating LP-WUS by terminal devices at the coverage boundary of LP-WUS will introduce a large power consumption overhead, affecting the energy-saving gain of LP-WUS.

[0103] Therefore, the present application provides a communication method, in which a corresponding scheme is designed for the activation conditions of LP-WUS to reduce the negative energy-saving benefits caused by unnecessary wake-up of MR. In the activation conditions of LP-WUS of the present application, when MR determines that the activation conditions of LP-WUS are met, LP-WUR is turned on. During the period of turning on LP-WUR, if the signal quality of LR continues to meet the activation conditions of LP-WUS, it is completely switched to LP-WUR operation; otherwise, if it is determined that the activation conditions of LP-WUS are not met during this period, LP-WUR is turned off and MR operation is returned. In this way, it is equivalent to continuing to judge whether the activation conditions of LP-WUS are met during the period of turning on LP-WUR when LP-WUR is turned on, so as to determine whether to keep LP-WUR operation or return to MR operation. In this way, compared with the existing UE supporting LP-WUS, when it is at the edge of LP-WUS coverage, if the MR is directly turned off when switching to LP-WUR, the problem of frequent and unnecessary switching due to the ping-pong problem of measurement caused by its own high mobility may be caused. The present application is equivalent to continuing to judge whether the activation conditions of LP-WUS are met according to the extended period of time when LP-WUR is turned on, and deciding whether to keep LP-WUR working or return to MR working according to the judgment result of the extended period of time. It can avoid the problem of frequent and unnecessary switching due to the ping-pong problem of measurement caused by its own high mobility, reduce the power consumption overhead of the terminal equipment, and improve the energy-saving gain of LP-WUS use.

[0104] Based on the above overview, as shown in Figure 4, a flow chart of a communication method provided by the present application is shown. The method can be applied to a terminal device or a device in a terminal device (such as a chip, etc.). The following description is given by taking the execution by the terminal device as an example. The terminal device includes MR and LP-WUR. The processing performed by a single execution subject in the method can also be divided into executions by multiple execution subjects, which can be logically and / or physically separated. The method includes the following process.

[0105] 401. The terminal device measures the signal quality of the serving cell through MR.

[0106] In some embodiments, the terminal device measures the signal quality of the serving cell through MR to measure whether the signal quality of the serving cell meets the first activation condition of LP-WUR. The MR measurement of the signal quality of the serving cell may be RRM measurement.

[0107] In some embodiments, the MR may perform RRM measurements periodically, aperiodically, or semi-statically. Aperiodic RRM measurements may be triggered by an event, for example. Semi-static RRM measurements may be performed periodically after activating RRM measurements through specific signaling. This application does not limit the manner in which the MR performs RRM measurements.

[0108] 402. If the signal quality of the serving cell measured by the MR meets the first activation condition of the LP-WUR, the terminal device measures the signal quality of the serving cell through the LP-WUR within the first time period.

[0109] Determining whether the signal quality of the serving cell measured by the MR meets the first activation condition of the LP-WUR may be performed by the MR.

[0110] In some embodiments, the method by which the MR determines whether the signal quality of the serving cell measured by the MR meets the first activation condition of the LP-WUR may be that the result of a single measurement sample meets the first activation condition, or the MR performs N RRM measurements and determines that the N measurement results meet the first activation condition, or the results of consecutive M (1 < M < N) measurement samples among the N measurements meet the first activation condition, or the results of any M measurement samples among the N measurements meet the first activation condition, or the results of M measurement samples separated by K measurement samples among the N measurements meet the first activation condition, or the average measurement value of consecutive M1 measurement values among the N measurements meets the first activation condition, or the average measurement value of any M1 measurement values among the N measurements meets the first activation condition, or the average measurement value of M1 measurement values separated by K1 among the N measurements meets the first activation condition. Among them, the average measurement value may also be replaced by a weighted average value or a minimum measurement value, etc. Among them, both M and N are integers.

[0111] Among them, the behavior of the MR measuring the signal quality of the serving cell may occur within a period of time. Therefore, in some embodiments, the first activation condition includes: within the second time period T meas the signal quality of the serving cell measured by the MR is greater than or equal to the first preset threshold. The first preset threshold can be understood as the threshold for the MR to determine whether to activate the LP-WUS or the threshold for activating the LP-WUR.

[0112] Exemplarily, the first activation condition may be expressed as: S MR > Threshold MR,entry + Offset1. The first preset threshold is Threshold MR,entry + Offset1. The first activation condition may also include the case where S MR = Threshold MR,entry + Offset1.

[0113] Among them, S MR Indicates that MR is in the second time period T meas Measure the signal quality of the serving cell, Threshold MR,entry Indicates the threshold for MR to activate LP-WUS, and Offset1 indicates the optional hysteresis value, which is typically a positive value. MR,entry The threshold value of the entry condition for MR switching to LP-WUR, which is currently being discussed in the standard, can be the same or different. MR,entry The threshold for activating the conditions for MR switching to LP-WUR, which is currently under discussion in the standard, is the same. It can be understood that the MR activation threshold for LP-WUS in this application is greater than the threshold for activating the conditions for MR switching to LP-WUR, which is currently under discussion. In this way, by raising the threshold for activating LP-WUR, if the signal quality of the serving cell measured by the MR meets the first activation condition, it means that the signal quality of the serving cell measured by the MR is better, and the signal quality on the LP-WUR is also higher, and the LP-WUR can be activated for wake-up signal monitoring.

[0114] Among them, the threshold value and hysteresis value for activating LP-WUS in the first activation condition can be based on the RSRP or RSRQ or RSSI or SINR value of SSB or the value of other reference signals. For details, please refer to the description of RRM measurement in this application. The threshold value and hysteresis value for activating LP-WUS in the first activation condition can be configured by sending broadcast signaling from the network device to the terminal device, or can be a predefined value in the terminal device, which is not limited in this application. Among them, the broadcast signaling can be, for example, RRC signaling, such as the system information block SIB, or it can be configured by sending dedicated signaling from the network device to the terminal device, such as the dedicated signaling is an RRC reconfiguration message.

[0115] In some embodiments, if the signal quality of the serving cell measured by the MR does not meet the first activation condition, the MR may remain in normal operation. That is, the MR performs normal non-connected state behaviors, such as monitoring paging or performing RRM measurements. In this case, it can be understood that the signal quality of the current serving cell is poor, and the signal quality measured by the LR should also be poor, making it inappropriate to activate LP-WUR and enter normal operation.

[0116] In some embodiments, if the signal quality of the service cell measured by MR meets the first activation condition, it means that the signal quality of the current service cell is good and the signal quality of LP-WUR is also good. LP-WUR can be turned on to enter normal working state.

[0117] In this application, when the LP-WUR enters normal working state, the LP-WUR not only supports receiving the wake-up signal, but also supports monitoring the LP-SS to measure the signal quality of the serving cell. The moment the LP-WUR is turned on is the starting moment of the first time period. The LP-WUR can start measuring the signal quality of the serving cell and monitor the wake-up signal when entering the first time period.

[0118] In some embodiments, turning on / opening the LP-WUR may refer to waking up the LP-WUR, or triggering the LP-WUR to exit a sleep state / sleep mode, or triggering the LP-WUR to enter an awake state / awake mode. For example, a signal or current may be sent to the LP-WUR via an MR or other device to wake up the LP-WUR. This application does not limit the method for turning on the LP-WUR.

[0119] In some embodiments, during the first time period T delay During the first time period T, the MR is in the first state, and the power consumption of the terminal device when the MR is in the first state is greater than the power consumption of the terminal device when the MR is in the off state. delay The system is in normal working condition or abnormal working condition.

[0120] For example, if the off state is understood as the ultra-deep sleep working state in Table 1, the first state can be a normal working state of PDCCH monitoring, or can also be one of the working states of deep sleep, light sleep or light-light sleep. In this way, the MR is in the first time period T delay When the MR is in one of the working states of deep sleep, light sleep or shallow sleep, if the result of judgment in step 403 is to allow the MR to enter the normal working state, compared with the power consumption and conversion delay of the MR converting from the off state to the normal working state, the power consumption of the MR converting from one of the working states of deep sleep, light sleep or shallow sleep to the normal working state in the present application is lower and the conversion delay is shorter.

[0121] 403. The terminal device determines whether the signal quality of the serving cell measured by the LP-WUR meets the second activation condition of the LP-WUR.

[0122] For example, when the LP-WUR is turned on, that is, the LP-WUR is in the first time period T delay When entering the normal working state, LP-WUR can start measuring the signal quality of the service cell, for example, it can perform RRM measurement to obtain the signal quality of the service cell, and determine whether the RRM measurement result meets the second activation condition of LP-WUR.

[0123] In some embodiments, the LP-WUR may measure the signal quality of the serving cell either periodically or aperiodically. For example, the LP-WUR can be triggered by an event to measure the signal quality of the serving cell. Alternatively, the signal quality measurement of the serving cell performed by the LP-WUR can also be semi-static. For example, when the LP-WUR receives a specific signaling to activate the LP-WUR to measure the signal quality of the serving cell, the LP-WUR measures the signal quality of the serving cell.

[0124] In some embodiments, the LP-WUR's measurement of the signal quality of the serving cell can be based on a reference signal, that is, the LP-WUR measures the signal quality of the serving cell according to the reference signal received from the network device. Here, the reference signal can be, for example, an SSB or an LP-SS or other reference signals. This application does not limit the type of the reference signal for the LP-WUR to measure the signal quality of the serving cell.

[0125] Similar to the method of determining whether the signal quality measured by the MR for the serving cell meets the first activation condition in step 402, determining whether the signal quality measured by the LP-WUR for the serving cell meets the second activation condition can be that the result of a single measurement sample meets the first activation condition, or the LP-WUR performs N' measurements of the serving cell, and it is determined that the results of the N' measurements meet the second activation condition, or the results of consecutive M' (1 < M' < N') measurement samples among the N' measurements meet the second activation condition, or the results of any M' measurement samples among the N' measurements meet the second activation condition, or the results of M' measurement samples spaced K' measurement samples apart among the N' measurements meet the second activation condition, or the average measurement value of consecutive M1' measurement values among the N' measurements meets the second activation condition, or the average measurement value of any M1' measurement values among the N' measurements meets the second activation condition, or the average measurement value of M1' measurement values spaced K1' measurement values apart among the N' measurements meets the second activation condition. Here, the average measurement value can also be replaced by a weighted average value or a minimum measurement value, etc. Here, both M' and N' are integers.

[0126] In some embodiments, the second activation condition includes: within the first time period T delay the signal quality measured by the LP-WUR for the serving cell is greater than or equal to the second preset threshold.

[0127] Exemplarily, the second activation condition can be expressed as: S LR > Threshold LR,entry + Offset2.

[0128] Here, S LR represents the signal quality measured by the LP-WUR for the serving cell within the first time period T delayMeasure the signal quality of the serving cell, Threshold LR,entry Indicates the threshold for LP-WUR to determine whether to activate LP-WUS. Offset2 indicates the optional hysteresis value, which can be a positive value. The second preset threshold is Threshold LR,entry +Offset2. The second activation condition here can also include S LR =Threshold LR,entry +Offset2 case.

[0129] Among them, Threshold LR,entry The form of Offset2 can be based on the LP-RSRP or LP-RSRQ or LP-RSSI or LP-SINR value of LP-SS, or based on RSRP or RSRQ or RSSI or SINR of SSB. This application does not limit the form of LP-WUR measuring the signal quality of the serving cell. LR,entry The hysteresis value Offset2 can be a broadcast signaling sent by the base station to the terminal device, such as RRC signaling, such as the system information block SIB, or a dedicated signaling sent by the network device to the terminal device for configuration, such as the dedicated signaling is an RRC reconfiguration message, or it can be a fixed value predefined in the terminal device through the protocol. This application does not limit the configuration method of the second preset threshold.

[0130] In this way, if the signal quality of the serving cell measured by LP-WUR meets the second activation condition, it means that the signal quality of the serving cell measured by LP-WUR is good, and the signal quality on LP-WUR is also high. LP-WUR is activated in the first time period T delay If the activation conditions of LP-WUS are continuously met within a certain period of time, LP-WUR can be kept in normal working state, such as performing wake-up signal monitoring or performing signal quality measurement of the serving cell.

[0131] Therefore, compared with the existing problem that when a UE supporting LP-WUS is at the edge of LP-WUS coverage and the MR is directly turned off when switching to the LR, frequent and unnecessary switching may occur due to the ping-pong problem of measurement caused by its own high mobility. In this application, it is equivalent to continuing to judge whether the activation conditions of LP-WUS are met according to a period of time extended when the LR is turned on, and then deciding whether to keep the LR working or return to the MR working according to the judgment result of the extended period of time. This can avoid the frequent and unnecessary switching problem caused by the ping-pong problem of measurement caused by its own high mobility, reduce the power consumption overhead of the terminal device, and improve the energy saving gain of the use of LP-WUS.

[0132] In some embodiments, the method further includes: if the signal quality of the service cell measured by the LP-WUR meets the second activation condition, the terminal device turns off the MR after the first time period. It can be understood here that if the signal quality of the service cell measured by the LP-WUR meets the second activation condition, it means that the signal quality on the LP-WUR is good, or the link quality of the LP-WUS is good, and when the network side sends the LP-WUS, the LP-WUR can receive the LP-WUS. At this time, the terminal device can completely switch to the LP-WUR for normal operation to monitor the LP-WUS sent by the base station for paging the terminal device. In addition, the terminal device can turn off the MR. Turning off the MR can be understood as the MR entering a sleep state or sleep mode, such as entering an ultra-deep sleep state.

[0133] In some embodiments, the method further includes: if the signal quality of the serving cell measured by the LP-WUR determines that the second activation condition of the LP-WUR is not satisfied, shutting down the LP-WUR. LR ≤Threshold LR,entry +Offset2, it is determined that the signal quality of the service cell measured by LP-WUR does not meet the second activation condition of LP-WUR, and the signal quality of LP-WUR is poor. LP-WUR may not receive the wake-up signal from the network side. At this time, the link quality on LP-WUR does not meet the conditions for LR to enter normal operation. Therefore, you can choose to turn off LP-WUR.

[0134] In some embodiments, if in the first time period T delay In the first time period T, the first state of MR is the normal working state of MR. delay Based on this, when deciding whether to turn off LP-WUR, the signal quality of the serving cell measured on the MR and whether the MR receives the paging message can also be considered.

[0135] Therefore, in the first time period T delay If the system is operating normally and MR is operating normally, you can perform one of the following actions:

[0136] 1) If LP-WUR is in the first time period T delay The signal quality of the serving cell measured within the first time period T satisfies the second activation condition, and the MR delay If the signal quality of the serving cell measured within the first time period satisfies the first activation condition, the MR is turned off after the first time period. delay The RRM measurement results of LP-WUR are shown in Figure 2. delayThe second activation condition is continuously satisfied within the first time period T delay If the RRM measurement results of MR continue to meet the first activation condition, it can be understood that the signal quality or link performance on LP-WUR and MR are good. If there is no data / service transmission on MR, LP-WUR can be kept in normal working state and MR enters the shutdown state to save power consumption of terminal equipment, thereby realizing the energy saving gain brought by LP-WUS to terminal equipment.

[0137] 2) If LP-WUR is in the first time period T delay The signal quality of the serving cell measured within the first time period T determines that the second activation condition is not met, or the MR is in the first time period T delay If the signal quality of the serving cell measured within the first activation period does not meet the first activation condition, the LP-WUR is turned off. That is, as long as the signal quality / link performance on the LP-WUR is poor and / or the signal quality / link performance on the MR is poor, the first time period T can be stopped. delay Based on the determination of the second activation condition and the first activation condition, the LP-WUR is directly / immediately shut down. This is because when the signal quality on the LP-WUR is poor, the LP-WUR may not receive the LP-WUS from the network, or the LP-WUR may not properly receive the wake-up signal, which will affect the MR's data transmission performance. If the signal quality on the MR is poor, the signal quality on the LP-WUR is also considered poor, and the LP-WUR cannot properly receive the LP-WUS. In this case, the MR can continue to operate normally.

[0138] Exemplarily, if the signal quality of the serving cell measured by the LP-WUR as described above satisfies the second activation condition, the situations where the signal quality of the serving cell measured by the LP-WUR does not satisfy the second activation condition can be as follows: the result of a single measurement sample of the signal quality of the serving cell measured by the LP-WUR does not satisfy the first activation condition; or, the LP-WUR performs N' measurements of the signal quality of the serving cell, and it is determined that at least one of the measurement results of all N' measurements does not satisfy the second activation condition; or, at least one of the measurement sampling results of at least M' (1 < M' < N') consecutive measurement samplings out of all N' measurements does not satisfy the second activation condition; or, at least one of the measurement sampling results of any M' measurement samplings out of all N' measurements does not satisfy the second activation condition; or, at least one of the measurement sampling results of M' measurement samplings with an interval of K' measurement samplings out of all N' measurements does not satisfy the second activation condition; or, the average measurement value of at least M1' consecutive measurement values out of all N' measurements does not satisfy the second activation condition; or, the average measurement value of any M1' measurement values out of all N' measurements does not satisfy the second activation condition; or, the average measurement value of M1' measurement values with an interval of K1' measurement values out of all N' measurements does not satisfy the second activation condition. Here, the average measurement value can also be replaced with a weighted average value or a minimum measurement value, etc.

[0139] Similarly, for the situation where the signal quality of the serving cell measured by the MR within the first time period does not satisfy the first activation condition, reference can be made to the description of the signal quality of the serving cell measured by the LP-WUR satisfying the second activation condition, which will not be elaborated here.

[0140] 3) If within the first time period T delay a wake-up signal of the LP-WUR is received, and / or a paging signal of the MR is received, then the LP-WUR is turned off. Turning off the LP-WUR here can be understood as stopping the determination of the second activation condition and the first activation condition during the first time period T delay and directly / immediately turning off the LR. Exemplarily, if within the first time period T delay the LP-WUR receives the LP-WUS, and analyzes the LP-WUS to determine that the LP-WUS carries the identification information of the terminal device or the information of the group to which the terminal device belongs, and carries the indication information indicating to wake up the MR, then the LP-WUR is turned off. At this time, only the MR continues to be in the normal working state. Or, if within the first time period T delay the MR receives a paging message. For example, after the MR monitors the paging DCI at the paging occasion and then monitors the paging message, if the paging message carries the identification information of the terminal device, it means that the terminal device is paged, and the LP-WUR is turned off while keeping the MR continuing to be in the normal working state.

[0141] For example, as shown in FIG5 , a LP-WUR and MR are delay Schematic diagram of the decision result of participating in the serving cell measurement when all are working normally at the beginning. meas The signal quality of the serving cell is measured at the start time of the LR in the second time period T meas Keep closed. If in the second time period T meas At the end time T1, determine MR in the second time period T meas If the signal quality of the serving cell measured within the time period satisfies the first activation condition, the terminal device turns on / on the LP-WUR at time T1 and enters the first time period T during which the LP-WUR normally operates. delay In the first time period T delay During this period, the MR can continue to monitor paging and perform measurements on the serving cell, and the LR can also monitor wake-up signals and perform measurements on the serving cell.

[0142] If LP-WUR in the first time period T delay The signal quality of the serving cell measured in the first time period satisfies the second activation condition, and the signal quality of the serving cell measured by the MR in the first time period satisfies the first activation condition. delay At the end time T2, MR is turned off;

[0143] If LP-WUR in the first time period T delay The signal quality of the serving cell measured at time T3 or a time before time T3 does not meet the second activation condition, or the MR is in the first time period T delay If the signal quality of the serving cell measured at time T3 or at a time before time T3 does not meet the first activation condition, the LP-WUR and MR can stop measuring the serving cell and stop judging the measurement results and activation conditions, and immediately shut down the LP-WUR. delay At time T3, LP-WUR is turned off;

[0144] If in the first time period T delay If the LP-WUR receives the LP-WUR wake-up signal at time T3 or some time before time T3, and / or the MR receives the MR paging signal at time T3 or some time before time T3, the LP-WUR is turned off. delay At time T3, LP-WUR is turned off.

[0145] In some embodiments, if in the first time period T delayWhen the first state of the MR is an abnormal operating state of the MR, the first state may be the first sleep state of the MR, and the first sleep state satisfies the following condition: the conversion power consumption of waking up the MR in the first sleep state is less than the conversion power consumption of waking up the MR in the second sleep state. The second sleep state may be, for example, an ultra-deep sleep state, a deep sleep state, or a light sleep state. For example, if the second sleep state is an ultra-deep sleep state, the first sleep state may be one of deep sleep / light sleep / light-light sleep. If the second sleep state is a deep sleep state, the first sleep state may be one of light sleep / light-light sleep. If the second sleep state is a light sleep state, the first sleep state may be a light-light sleep state.

[0146] The first sleep state also satisfies the following conditions: the average power consumption of the communication module of the terminal device when the MR is in the first sleep state is greater than the average power consumption of the communication module when the MR is in the second sleep state, and / or the minimum power consumption of the communication module when the MR is in the first sleep state is greater than the maximum power consumption of the communication module when the MR is in the second sleep state. The communication module may include a radio frequency or antenna module of the terminal device and a modem in a processor of the terminal device, and may also include a power module of the terminal device. If the average power consumption of the communication module of the MR in the first sleep state is higher than the average power consumption of the second sleep state, or if the minimum power consumption of the communication module of the MR in the first sleep state is higher than the maximum power consumption of the second sleep state, it can be understood that the first sleep state is one of deep sleep, light sleep, or shallow-light sleep.

[0147] That is, if MR in the second time period T meas When the signal quality of the internal measurement serving cell meets the first activation condition, the MR enters the first state while the LP-WUR is turned on. The first state is one of deep sleep / light sleep / shallow light sleep.

[0148] Among them, the first state can be understood as a transition state. This is because the MR in ultra-deep sleep state is usually understood as the MR off state. The standard has not yet clarified the software and hardware design of the terminal device's receiver. It may happen that the MR and LP-WUR cannot be turned on synchronously. At this time, the MR can be adjusted to a transition state of lighter sleep, such as deep sleep, light sleep, shallow light sleep, etc. This application does not limit the transition state. And once in the first time period T delay When it is judged that the second activation condition is not met and LP-WUR needs to be turned off and MR needs to be woken up, the conversion power consumption of waking up MR is smaller than that of waking up MR when MR is in the off state, which is beneficial to saving power consumption of the terminal device and has a shorter conversion delay.

[0149] When MR is in the first time period Tdelay When the MR is in one of the states of deep sleep / light sleep / light sleep, the MR does not participate in the measurement of the serving cell and does not receive paging signals. Therefore, in the first time period T delay Therefore, in some embodiments, after step 403, the following possible situations are also included:

[0150] 1) If in the first time period T delay If the signal quality of the serving cell measured by LP-WUR meets the second activation condition, then in the first time period T delay Then turn off MR. That is, in the first time period T delay After that, MR enters the normal sleep state, or enters the shutdown state. At this time, it is equivalent to the terminal device completely switching to LP-WUR operation, and LP-WUR can monitor the wake-up signal and measure the signal quality of the serving cell. MR entering the normal sleep state can be understood as MR switching from one of the deep sleep / light sleep / light sleep states to the normal sleep state, such as entering the ultra-deep sleep state. For example, referring to Figure 5, if in the first time period T delay If the signal quality of the serving cell measured by the LP-WUR meets the second activation condition, the LP-WUR may instruct the MR to shut down at time T2.

[0151] 2) If in the first time period T delay If the signal quality of the serving cell measured by the LP-WUR does not meet the second activation condition, the LP-WUR is turned off and the MR in the first state is awakened to enter the normal working state. delay If, at some point within the time frame, the signal quality of the serving cell measured by the LP-WUR does not meet the second activation condition, for example, at time T3 shown in FIG5 , the signal quality of the serving cell does not meet the second activation condition, the LP-WUR may awaken the MR in the first state to a normal operating state at time T3 and shut down the LP-WUR. Alternatively, other modules in the terminal device may instruct the MR to enter a normal operating state upon receiving an instruction from the LP-WUR.

[0152] 3) If in the first time period T delay In other words, if the LP-WUR wake-up signal is received during the first time period T, the LP-WUR is turned off and the MR in the first state is awakened to enter the normal working state. delay Within the first time period T, the LP-WUR receives the LP-WUS indicating that the terminal device can stop delayAccording to the determination of the second activation condition, the LP-WUS is turned off and the MR is awakened from the first state. The LP-WUS indicating the terminal device may be an LP-WUS carrying identification information of the terminal device, or an LP-WUS carrying group information to which the terminal device belongs.

[0153] Therefore, the present application can be implemented by MR in the second time period T meas When it is determined to activate LP-WUR, the first time period T after waking up LP-WUR may be delay Continue to judge whether the activation conditions of LP-WUR are met, that is, combine the more rigorous activation conditions of the first activation condition and the second activation condition to determine whether to keep LP-WUR working normally and turn off MR, or turn off LP-WUR and let MR work normally, so as to avoid the frequent and unnecessary switching problems caused by the measurement ping-pong problem due to the high mobility of the terminal device itself when the terminal device is at the coverage edge of LP-WUS, reduce the power consumption overhead of the terminal device, and improve the energy saving gain of LP-WUS.

[0154] In some embodiments, optionally, in the first time period T delay After the switch between MR and LP-WUR occurs at the end of the first time period T delay After the switch between MR and LP-WUR occurs at a certain moment within the period, in the third time period T switch The terminal device may not make the judgment of the first activation condition / the second activation condition to avoid frequent switching between MR and LP-WUR.

[0155] In some embodiments, T in this application meas 、T delay and T switch The time unit can be a system frame number (SFN), subframe, time slot, symbol, or time length (in seconds or milliseconds). It can be configured by the network device to the terminal device, or it can be a value specified by the protocol, or it can be pre-configured in the terminal device, such as in the subscriber identity module (SIM) card of the terminal device. The specific implementation method can be to configure a continuous length of T meas or T delay or T switch The timer can also be a timer in which the terminal device calculates a certain moment based on the timeline and performs related actions before the moment.

[0156] In some embodiments, the above method process of the present application can be applied to terminal devices that meet specific conditions. For example, when the terminal device is at the edge of the coverage of LP-WUS and / or the terminal device is in a high-speed moving state, the above steps 401 to 403 can be executed.

[0157] Therefore, the above-mentioned if the signal quality of the service cell measured by MR meets the first activation condition of LP-WUR, then the signal quality of the service cell is measured by the low-power wake-up receiver LP-WUR within the first time period, including: if the signal quality of the service cell measured by MR meets the first activation condition of LP-WUR, and at least one of the first conditions is met, then the signal quality of the service cell is measured by LP-WUR within the first time period.

[0158] Among them, the first condition includes: the signal quality of the service cell or neighboring cell measured by MR or LP-WUR in the third time period is less than or equal to the third preset threshold; or the change in the signal quality of the service cell or neighboring cell measured by MR or LP-WUR in the fourth time period is greater than or equal to the fourth preset threshold.

[0159] In this way, when the signal quality of the serving cell or the neighboring cell measured by MR or LP-WUR in the third time period is less than or equal to the third preset threshold, it can be understood that the terminal device is at the edge of the coverage of LP-WUS, the link performance of LP-WUS is poor, and LP-WUS may not be received. According to the above method process, it can be judged that MR is working normally or LP-WUR is working normally. When the change in the signal quality of the serving cell or the neighboring cell measured by MR or LP-WUR in the fourth time period is greater than or equal to the fourth preset threshold, it can be understood that the terminal device is in a high-speed moving state, and the terminal device may frequently switch between MR and LP-WUR. If the dual activation condition design of the present application is followed, unnecessary switching of the terminal device can be reduced, and the power consumption of the terminal device can be reduced.

[0160] The third preset threshold and the fourth preset threshold may be independent of the first activation condition and the second activation condition, and the present application does not limit the setting of the third preset threshold and the fourth preset threshold.

[0161] In some scenarios, LP-WUR is designed with low power consumption characteristics, resulting in the inability to guarantee the accuracy of the signal quality measurement results of the LP-WUR's serving cell. If the LP-WUR's measurement results are inaccurate or unreliable, the activation / deactivation LP-WUS process triggered by LP-WUR may also be unreliable. For example, when the measurement of the terminal device using LP-WUR deviates from the actual measurement (such as being too low), it may happen that the LP-WUR can still receive the LP-WUS, but because the measurement result is lower than the LP-WUS deactivation threshold, it causes unnecessary switching from LP-WUR to MR. Therefore, unnecessary switching caused by the unreliable signal quality measurement results of the serving cell such as LP-WUR will also introduce a large power consumption overhead, affecting the energy-saving gain of the use of LP-WUS.

[0162] Therefore, the present application provides a communication method, in which a corresponding deactivation scheme is designed for the deactivation conditions of LP-WUS to reduce the negative energy-saving benefits caused by unnecessary wake-up of MR. In the present application, in addition to the measurement result of the signal quality of the serving cell on the LP-WUR of the terminal device meeting the conditions for deactivating LP-WUS, the terminal device can also additionally determine which deactivation behavior to perform based on whether LP-WUS is received within a period of time. In this way, the power consumption overhead caused by the unnecessary behavior of waking up the MR of the terminal device can be reduced, and the impact on the energy-saving gains brought by the use of LP-WUS can be reduced.

[0163] FIG6 is a flow chart of a communication method, which is applied to a terminal device or a device in a terminal device (such as a chip, etc.). The following description is based on the example of execution by a terminal device. The terminal device includes an MR and an LP-WUR. The processing performed by a single execution subject in the method can also be divided into multiple execution subjects, which can be logically and / or physically separated. The method includes the following process.

[0164] 601. The terminal device monitors the wake-up signal on the LP-WUR. Then, step 602 or step 603 is executed.

[0165] This means that the LP-WUR of the terminal device is operating normally, while the MR is in a shutdown state, for example, in an ultra-deep sleep state.

[0166] When the LP-WUR operates normally, the LP-WUR can monitor the LP-WUS and the LP-SS, that is, monitor the wake-up signal and perform measurements of the serving cell.

[0167] 602. If the terminal device receives a wake-up signal from LP-WUR within the first time period, or the time interval from the last time the wake-up signal from LP-WUR was received is less than or equal to the first time threshold, the terminal device keeps LP-WUR in a normal working state.

[0168] The first time period may be a time period that ensures that the terminal device can perform at least one serving cell measurement.

[0169] For example, FIG7 is a LP-WUR in the first time period T detect As shown in (a) of FIG7 , if in the first time period T detect If the LP-WUR of the terminal device receives the LP-WUS, for example, if the LP-WUS is received at time T2, it can be considered that the link performance of the LP-WUS is good, or the signal quality of the LP-WUP is good, or the terminal device is still within the coverage of the LP-WUS. The terminal device can keep the LP-WUR in normal working state, and the terminal device does not need to switch to MR operation.

[0170] Alternatively, in the first time period T detect When the terminal device determines that the time interval from the last time it received the wake-up signal from the LP-WUR is less than or equal to the first time threshold, it also considers that the link performance of the LP-WUS is good, or that the signal quality of the LP-WUP is good, or that the LP-WUR has recently detected the wake-up signal and the terminal device is still within the coverage of the LP-WUS, the terminal device can keep the LP-WUR in normal working state, and the terminal device does not need to switch to MR operation. For example, if the LP-WUR receives the LP-WUS at a certain time before time T1, the LP-WUR enters the first time period T detect After that, it is determined at multiple times that the time interval from the last time LP-WUS was received is less than the first time threshold, and the terminal device determines that it does not need to switch to MR operation, or LP-WUR is in the first time period T detect LP-WUS is received at time T2 within the time period, and LP-WUR determines that detect The time intervals between the multiple moments after moment T2 and moment T2 are less than the first time threshold, and the terminal device determines that it does not need to switch to MR operation.

[0171] 603. If at least one of the second conditions is met within the first time period, shut down the LP-WUR or keep the LP-WUR in a normal working state.

[0172] In some embodiments, the second condition includes: not receiving a wake-up signal from the LP-WUR; or, a time interval from the last time a wake-up signal from the LP-WUR was received is greater than a first time threshold.

[0173] For example, referring to FIG7 (a), if LP-WUR is in the first time period T detect If the LP-WUS is not received for a period of time, it may be that the LP-WUR is no longer within the LP-WUS coverage area, or the LP-WUS link performance is poor. In this case, the LP-WUR can be shut down. However, it is also possible that the LP-WUR is still within the LP-WUS coverage area, or the LP-WUS link performance is good, but there is no LP-WUS to receive. In this case, the LP-WUR can be kept in normal operation. Whether to shut down the LP-WUR or keep it in normal operation can also be determined based on other conditions.

[0174] Alternatively, if LP-WUR has received LP-WUS at some time before T1, in the first time period T detect At certain moments within the time period, such as at time T3, LP-WUR determines that the time interval since the last time it received the wake-up signal from LP-WUR is greater than the first time threshold. The terminal device may still be within the coverage of LP-WUS, but there is no LP-WUS to receive. Alternatively, it is also possible that LP-WUR is no longer within the coverage of LP-WUS. Whether to shut down LP-WUR or keep LP-WUR in normal working state can be further determined based on other conditions.

[0175] Therefore, in some embodiments, turning off the LP-WUR includes: if at least one of the second conditions is met within the first time period, and the signal quality of the service cell measured by the LP-WUR meets the deactivation condition of the LP-WUR, then turning off the LP-WUR and waking up the MR to enter a normal working state.

[0176] For example, referring to FIG7(b), if LP-WUR is in the first time period T detect If LP-WUS is not received within 10 seconds and the signal quality of the serving cell measured by LP-WUR meets the deactivation condition of LP-WUR, this situation can be understood as LP-WUR is no longer within the coverage of LP-WUS, or the link performance of LP-WUS is poor and is no longer suitable for LP-WUR to maintain normal working state. At this time, LP-WUR can be turned off and MR can be awakened to enter normal working state. For example, LP-WUR is in the first time period T detectIf it is determined that LP-WUS has not been received at T4, and the signal quality of the serving cell measured at T4 meets the deactivation condition of LP-WUR, LP-WUR can be immediately turned off at T4, and MR can be awakened to enter normal working state.

[0177] Alternatively, referring to FIG. 7( b ), if LP-WUR is in the first time period T detect At some point in the time interval, it is determined that the time interval from the last time the LP-WUR wake-up signal was received is greater than the first time threshold, and the signal quality of the serving cell measured by the LP-WUR meets the deactivation condition of the LP-WUR. This situation can be understood as the LP-WUR is no longer within the coverage of the LP-WUS, or the link performance of the LP-WUS is poor and is no longer suitable for the LP-WUR to maintain normal working state. At this time, the LP-WUR can be turned off and the MR can be awakened to enter normal working state. For example, the LP-WUR is in the first time period T detect If it is determined at time T4 or at a time before time T4 that the time interval from the last time the wake-up signal of the LP-WUR was received is greater than the first time threshold, and the signal quality of the service cell measured at time T4 meets the deactivation condition of the LP-WUR, the LP-WUR can be turned off immediately at time T4, and the MR can be awakened to enter normal working state.

[0178] In some embodiments, turning off the LP-WUR includes: if at least one of the second conditions is met within the first time period, the signal quality of the service cell measured by the LP-WUR does not meet the deactivation condition of the LP-WUR, and no wake-up signal of the LP-WUR is received within the second time period, then turning off the LP-WUR after the second time period and waking up the MR to enter a normal working state; wherein the second time period is after the first time period.

[0179] For example, referring to FIG7(c), if LP-WUR is in the first time period T detect If LP-WUS is not received within the first time period T, and the signal quality of the serving cell measured by LP-WUR does not meet the deactivation condition of LP-WUR, it can be understood that the measurement result of the signal quality of the serving cell measured by LP-WUR may be unreliable, and the measurement result may be larger than the actual measurement result, but the terminal device is already outside the coverage of LP-WUS, which makes the link performance of LP-WUS poor and cannot receive LP-WUS. At this time, the terminal device can continue to receive LP-WUS in the first time period T. detect The second time period T starts at the end time T5 delay Make a judgment within the second time period T delay If LP-WUS is not received within the second time period T delayAt the end time T6, LP-WUR is turned off and MR is awakened to enter normal working state. Another case is that if in the first time period T detect There is no LP-WUS to receive in the LP-WUR, the signal quality of the service cell measured by the LP-WUR does not meet the deactivation condition of the LP-WUR, or the measurement result of the signal quality of the service cell measured by the LP-WUR may be unreliable, but the terminal device is already out of the coverage of the LP-WUS, in the second time period T delay Continue to determine whether LP-WUS is received within the second time period T delay If LP-WUS is not received within the second time period T delay At the end time T6, LP-WUR is turned off and MR is awakened to enter normal working state.

[0180] Similarly, if LP-WUR is in the first time period T detect At some moment in the period, it is determined that the time interval from the last time the wake-up signal of the LP-WUR was received is greater than the first time threshold, and the signal quality of the serving cell measured by the LP-WUR does not meet the deactivation condition of the LP-WUR. It may also be that the measurement result of the signal quality of the serving cell measured by the LP-WUR may be unreliable, but the terminal device is already out of the coverage of the LP-WUS. In the second time period T delay Continue to determine whether LP-WUS is received within the second time period T delay If LP-WUS is not received within the second time period T delay At the end time T6, LP-WUR is turned off and MR is awakened to enter normal working state.

[0181] In some embodiments, turning off the LP-WUR includes: if at least one of the second conditions is met within a first time period, the signal quality of the service cell measured by the LP-WUR does not meet the deactivation conditions of the LP-WUR, but within a second time period, the signal quality of the service cell measured by the LP-WUR meets the deactivation conditions of the LP-WUR, then turning off the LP-WUR and waking up the MR to enter a normal working state; wherein the second time period is after the first time period.

[0182] For example, referring to FIG7(c), if LP-WUR is in the first time period T detect If LP-WUS is not received within the first time period T and the signal quality of the serving cell measured by LP-WUR does not meet the deactivation conditions of LP-WUR, it can be understood that the measurement result of the signal quality of the serving cell measured by LP-WUR may be unreliable, but the terminal device is already out of the coverage of LP-WUS. If detectThe second time period T after the end time T5 delay Continue to measure the cell, and if the signal quality of the measured serving cell meets the deactivation condition of LP-WUR, it can be understood that the signal quality of LP-WUR is already poor, or the terminal device is already out of the coverage of LP-WUS. LP-WUR can be turned off and MR can be awakened to enter normal working state. Another case is that if in the first time period T detect There is no LP-WUS to receive in the LP-WUR, and the signal quality of the serving cell measured by the LP-WUR does not meet the deactivation conditions of the LP-WUR, but in the first time period T detect The second time period T after the end time T5 delay Continue to perform cell measurement, and if the signal quality of the measured serving cell meets the deactivation condition of LP-WUR, it can be understood that the signal quality of LP-WUR is already poor, or the terminal device is already out of the coverage of LP-WUS. LP-WUR can be turned off and MR can be awakened to enter normal working state. For example, referring to (c) in Figure 7, in the second time period T delay When the measurement result at time T7 indicates that the signal quality of the serving cell meets the deactivation condition of LP-WUR, LP-WUR can be immediately turned off at time T7, and MR can be awakened to enter normal working state.

[0183] Similarly, if LP-WUR is in the first time period T detect At some point in the time interval, it is determined that the time interval from the last time the wake-up signal of LP-WUR was received is greater than the first time threshold, and the signal quality of the serving cell measured by LP-WUR does not meet the deactivation condition of LP-WUR. It may also be that the measurement result of the signal quality of the serving cell measured by LP-WUR may be unreliable, but the terminal device is already out of the coverage of LP-WUS. It is also possible that in the first time period T detect During the LP-WUR period, there is no need to receive LP-WUS. If in the second time period T delay When the measurement result at T7 indicates that the signal quality of the serving cell meets the deactivation condition of LP-WUR, it can be understood that the signal quality of LP-WUR is already poor, or that the terminal device is already out of the coverage range of LP-WUS. In this case, LP-WUR can be immediately turned off at T7, and MR can be awakened to enter normal working state.

[0184] In some embodiments, when at least one of the second conditions is met within the first time period, keeping the LP-WUR in a normal working state includes: if a wake-up signal of the LP-WUR is received within the second time period, keeping the LP-WUR in a normal working state; wherein the second time period is after the first time period.

[0185] That is to say, if the LP-WUR wake-up signal is not received within the first time period, and the signal quality of the service cell measured by the LP-WUR does not meet the LP-WUR deactivation conditions, the terminal device may continue to make judgments within the second time period. If the LP-WUR wake-up signal is received within the second time period, the LP-WUR will remain in normal working state.

[0186] Alternatively, if within the first time period, the time interval from the last time the LP-WUR wake-up signal was received is greater than the first time threshold, and the signal quality of the service cell measured by the LP-WUR does not meet the LP-WUR deactivation conditions, the terminal device may continue to make judgments within the second time period. If the LP-WUR wake-up signal is received within the second time period, the LP-WUR is kept in a normal working state.

[0187] Exemplarily, referring to (d) in FIG7 , similar to the case of (c) in FIG7 , if the wake-up signal of the LP-WUR is not received within the first time period, and the signal quality of the service cell measured by the LP-WUR does not meet the deactivation condition of the LP-WUR, or, within the first time period, the time interval from the last time the wake-up signal of the LP-WUR is received is greater than the first time threshold, and at time T5, the signal quality of the service cell measured by the LP-WUR does not meet the deactivation condition of the LP-WUR, it is possible that the LP-WUR is in the first time period T detec t The measurement result of the signal quality of the serving cell may be unreliable, but the terminal device is already out of the coverage of the LP-WUS. Therefore, the signal quality of the serving cell may be measured in the second time period T delay Continue to judge within the second time period T delay The wake-up signal of LP-WUR is received at T8 ， LP-WUR can be maintained to continue in the second time period T delay The remaining time period is in normal working state, and MR continues to be in the closed state.

[0188] In some embodiments, the LP-WUR measures whether the signal quality of the serving cell meets the deactivation condition of the LP-WUR. The method can be similar to the method in step 402 where the MR determines whether the signal quality of the MR measurement serving cell meets the first activation condition of the LP-WUR. That is, the result of a single measurement sampling by the LP-WUR meets the deactivation condition of the LP-WUR / LP-WUS, or the LP-WUR performs N measurements of the signal quality of the serving cell, and determines that the results of the N measurements meet the deactivation condition of the LP-WUR / LP-WUS, or the results of consecutive M (1 < M < N) measurement samplings among the N measurements meet the deactivation condition of the LP-WUR / LP-WUS, or the results of any M measurement samplings among the N measurements meet the deactivation condition of the LP-WUR / LP-WUS, or the results of M measurement samplings with an interval of K measurement samplings among the N measurements meet the deactivation condition of the LP-WUR / LP-WUS, or the average value of consecutive M1 measurement values among the N measurements meets the deactivation condition of the LP-WUR / LP-WUS, or the average value of any M1 measurement values among the N measurements meets the deactivation condition of the LP-WUR / LP-WUS, or the average value of M1 measurement values with an interval of K1 measurement values among the N measurements meets the deactivation condition of the LP-WUR / LP-WUS. Among them, the average measurement value can also be replaced by a weighted average value or a minimum measurement value, etc. Among them, both M and N are integers.

[0189] In some embodiments, when the LP-WUR detects / receives the LP-WUS, it can be understood that the LP-WUR receives the LP-WUS and successfully decodes the information carried by the LP-WUS.

[0190] In some embodiments, the deactivation condition of the LP-WUR includes: within the first time period T detect the signal quality measured by the LP-WUR for the serving cell is less than the fifth preset threshold.

[0191] Exemplarily, the deactivation condition of the LP-WUR can be expressed as: S LR <Threshold LR,exit - Offset3.

[0192] Among them, S LR represents the signal quality measured by the LP-WUR for the serving cell within the first time period T detect Threshold LR,exit represents the threshold for the LP-WUR to determine whether to deactivate the LP-WUS, and Offset3 represents an optional hysteresis value, which can be a positive value. The fifth preset threshold is Threshold LR,exit - Offset3. Here, the deactivation condition of the LP-WUR can also include S LR = ThresholdLR,exit -Offset3 situation.

[0193] Among them, Threshold LR,exit The form of Offset3 can be based on the LP-RSRP or LP-RSRQ or LP-RSSI or LP-SINR value of LP-SS, or it can be based on RSRP or RSRQ or RSSI or SINR of SSB. This application does not limit the form of LP-WUR measuring the signal quality of the serving cell. LR,exit The hysteresis value Offset3 can be configured to the terminal device by sending broadcast signaling from the base station to the terminal device, such as broadcasting SIB through system messages, or dedicated signaling, such as RRC messages, or it can be a fixed value predefined in the terminal device through a protocol. This application does not limit the configuration method of the fifth preset threshold.

[0194] In some embodiments, T in the above process delay , time interval, T detect The time unit of the time length threshold can be SFN, subframe, time slot, symbol, or time length (in seconds or milliseconds). It can be configured by the network device to the terminal device, or it can be a value specified by the protocol, or it can be pre-configured in the terminal device, for example, in the SIM card of the terminal device. delay , time interval, T detect The implementation method can be to configure a continuous length of T delay or time interval or T detect A timer can also be a terminal device that calculates a certain time point based on a timeline and performs related actions before the time point.

[0195] In some embodiments, after switching between MR and LP-WUR occurs, the terminal device may not determine the deactivation condition or activation condition of LP-WUR within a certain period of time to avoid frequent switching between MR and LP-WUR.

[0196] In some embodiments, if a wake-up signal of the LP-WUR is received within a first time period, or a time interval from the last time a wake-up signal of the LP-WUR is received is less than or equal to a first time threshold, maintaining the LP-WUR in a normal working state includes:

[0197] If a wake-up signal of LP-WUR is received within the first time period, or the time interval from the last time a wake-up signal of LP-WUR is received is less than or equal to the first time threshold, and at least one of the first conditions is met, keeping LP-WUR in a normal working state includes: the signal quality of the service cell or the neighboring cell measured by MR or LP-WUR within the third time period is less than or equal to the third preset threshold; or the change in the signal quality of the service cell or the neighboring cell measured by MR or LP-WUR within the fourth time period is greater than or equal to the fourth preset threshold.

[0198] That is, the above method process of the present application can be applied to terminal devices that meet specific conditions. For example, when the terminal device is at the edge of the coverage of LP-WUS and / or the terminal device is in a high-speed moving state, the above steps 601 to 603 can be executed.

[0199] Therefore, in this application, when LP-WUR is working normally, this application determines whether to keep LP-WUR working normally or switch to MR working normally by designing more stringent judgment conditions, which can avoid the problem of unnecessary switching caused by misjudgment due to unreliable LP-WUR measurement results. For example, due to inaccurate measurement of LP-WUR, when the terminal device is at the coverage boundary of LP-WUS, LP-WUR determines through measurement results that the deactivation conditions of LP-WUS are met. At this time, the terminal device should wake up MR and turn off LP-WUR. However, if there is normal reception and decoding of LP-WUS within a certain period of time, it means that the terminal device is still within the LP-WUS range and the LP-WUR measurement is inaccurate. In this case, the terminal device should slow down the behavior of switching back to MR.

[0200] In this way, compared with the design of LP-WUS deactivation conditions in the current standard, this application proposes a decision scheme for LP-WUS deactivation conditions based on LP-WUS reception and LP-WUR measurement results to avoid unnecessary switching caused by misjudgment due to inaccurate measurements of terminal devices at the edge of LP-WUS coverage.

[0201] In the embodiments of the present application, MR, LP-WUR, etc. can also be replaced by other names, and their functions or meanings do not change due to the name change. For example, MR can be replaced by the first receiver, and LP-WUR can be replaced by the second receiver.
