Description

Communication method and device, and computer readable storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communications method and apparatus, and a computer readable storage medium.

Background

In a wireless communication system, for a terminal device in an idle state or inactive state, it is necessary to periodically wake up to monitor paging signaling in order to know whether there is own called service. The period of listening for pages is network configurable, and may be hundreds of milliseconds (ms) or thousands of ms, or longer.

In order to further reduce the Power consumption of the idle/inactive terminal device, a new Low Power consumption Wake-Up Signal (LP-WUS) is introduced, the terminal device needs to use a specific receiver when receiving the Wake-Up Signal, while the receiver normally used for receiving paging can be turned off, and the whole terminal device can be in an extremely Low Power consumption state. If the terminal receives the own LP-WUS wake-up signal, the wireless transceiver which performs communication at ordinary times is triggered to perform work, such as starting to receive paging (when the LP-WUS cannot contain personal identification of the terminal and only can contain packet identification of a plurality of terminals), or directly triggering a random access flow (when the LP-WUS contains personal identification of the terminal). The terminal device can further save power consumption by means of the LP-WUS. It should be noted that the newly introduced wake-up signal may be referred to by other names, such as a low power activation signal.

In practice, the coverage of the LP-WUS may not be as good as that of the normal physical downlink control channel (Physical Downlink Control Channel, PDCCH), i.e. its coverage may not be sufficient to cover the whole cell. The terminal device can only apply LP-WUS (i.e. in an extremely low power consumption state) within the coverage of the LP-WUS. Once out of the LP-WUS coverage, the terminal device needs to receive a general page, at which point the terminal device cannot be in an extremely low power consumption state. The network configures a signal threshold for the terminal device applying LP-WUS so that the terminal device applying LP-WUS can determine whether to leave the coverage area of LP-WUS according to the signal strength of LP-WUS.

Terminal devices supporting LP-WUS need to camp on a cell that can provide LP-WUS first, and this cell may not currently be using LP-WUS, and thus may not be able to directly use the LP-WUS signal to detect/determine whether LP-WUS can be applied in this cell. In addition, how to select a suitable cell to apply LP-WUS is also a technical problem to be solved for the connected terminal device.

The terminal device may also be referred to as a User Equipment (UE), a terminal, etc.

As described in the background, a terminal device supporting LP-WUS first needs to camp on a cell that can provide LP-WUS, and this cell may not currently be using LP-WUS, and thus may not be able to directly detect/determine whether LP-WUS can be applied in this cell using the LP-WUS signal. In addition, how to select a suitable cell to apply LP-WUS is also a technical problem to be solved for the connected terminal device.

Further, considering that different cells may employ different LP-WUS coverage thresholds, the terminal device needs to camp on a cell where LP-WUS can be applied more surely.

Further, how to select a suitable cell to camp on and apply LP-WUS from a plurality of candidate cells (i.e. neighbor cells) is also a technical problem to be solved in the case that the terminal device finds that a plurality of candidate cells exist.

In the technical scheme of the application, for the terminal equipment in an idle state or a non-activated state, the second difference can be obtained by measuring the signal quality of the SSB in a cell not applying the LP-WUS, the first difference can be obtained by measuring the signal quality of the LP-WUS in the cell applying the LP-WUS, and then the target cell is determined to access by combining the frequency priority, for the terminal equipment in a connected state, the signal quality of the SSB can be measured in the cell not applying the LP-WUS, the signal quality of the LP-WUS can be measured in the cell applying the LP-WUS, and the network equipment can select a proper target cell to inform the terminal equipment, thereby ensuring that the terminal equipment can access the proper target cell to apply the LP-WUS.

In order that the above objects, features and advantages of the application will be readily understood, a more particular description of the application will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.

Referring to fig. 1, the method provided by the application specifically includes the following steps:

And 101, accessing the terminal equipment into the target cell. Wherein the target cell is determined based on one or more parameters of a first difference in signal quality of the low power wake-up signal LP-WUS with a first signal threshold, a second difference in signal quality of the synchronization signal block SSB with a second signal threshold, both of which are related to the coverage of the LP-WUS, and/or the frequency priority of the cell.

It will be appreciated that in a specific implementation, the communication method may be implemented in a software program running on a processor integrated within a chip or a chip module. The method may also be implemented by combining software with hardware, and the application is not limited.

In this embodiment, for the terminal device supporting LP-WUS, it is necessary to consider camping on the cell supporting LP-WUS so that better power saving can be achieved. For a cell supporting LP-WUS, two scenarios are possible:

Scenario 1, cell has not yet applied LP-WUS;

Scenario 2, the cell has started to apply LP-WUS.

In scenario 1, it is not possible for a terminal device entering the cell to detect and determine from the LP-WUS whether it is suitable to camp on the own cell application LP-WUS. In this case, a second signal threshold may be set that is related to the coverage of the LP-WUS. In particular, the second signal threshold may be determined based on the coverage of the LP-WUS. For example, the transmit power of the synchronization signal block (Synchronization Signal Block, SSB) is 30dBm, the signal quality attenuation at the coverage edge SSB of LP-WUS is 25dBm, and then the second signal threshold may be set to 25dBm.

In this embodiment, for terminal devices in idle or inactive state, the second difference may be obtained by measuring the signal quality of SSB in cells where LP-WUS is not applied. For terminal devices in a connected state, the signal quality of the SSB may be measured in a cell to which the LP-WUS is not applied, reported to the network device, and a second difference may be obtained by the network device.

In particular, in case the second difference is larger than zero, i.e. the signal quality of the SSB is higher than the second signal threshold, it is indicated that the terminal device is in the coverage of the LP-WUS, where the LP-WUS can be applied.

In scenario 2, the terminal device may detect that the LP-WUS has acquired signal quality because the cell has deployed the LP-WUS (may broadcast the corresponding configuration and coverage values of the LP-WUS).

In this embodiment, for terminal devices in idle or inactive state, a first difference is obtained by measuring the signal quality of LP-WUS in the cell in which the LP-WUS is applied. For terminal devices in a connected state, the signal quality of the LP-WUS may be measured in the cell in which the LP-WUS is applied and reported to the network device, and the first difference is obtained by the network device.

In particular, in case the first difference is larger than zero, i.e. the signal quality of the LP-WUS is higher than the first signal threshold, it is indicated that the terminal device is in the coverage of the LP-WUS, in which cell the LP-WUS can be applied.

It should be noted that, in the scenario 2, the terminal device may also measure the signal quality of the SSB and obtain the second difference.

It will be appreciated that the signal Quality for LP-WUS, the signal Quality for SSB, the first signal threshold, and the second signal threshold may be in the form of reference signal received Power (REFERENCE SIGNAL RECEIVING Power, RSRP), reference signal received Quality (REFERENCE SIGNAL RECEIVING Quality, RSRQ), signal-to-interference-plus-noise ratio (Signal to Interference plus Noise Ratio, SINR), etc., as the application is not limited in this regard.

Further, multiple frequency points usually cover the same area at the same time, and then a suitable target cell needs to be selected from candidate cells corresponding to the multiple frequency points. Therefore, after the first difference and/or the second difference are obtained, the target cell can be determined to be accessed by combining the frequency priority, so that the terminal equipment can be ensured to access the appropriate target cell application LP-WUS.

In this embodiment, the manner of determining the target cell may include one or more of the following:

in the mode 1, the target cell is a cell having the largest first difference and/or second difference among the plurality of candidate cells.

In the mode 2, the target cell is a cell with the largest first difference and/or the largest second difference among at least one candidate cell except for the candidate cell with the lowest frequency priority.

In the mode 3, the target cell is a cell with the first difference and/or the second difference higher than a preset threshold and the highest frequency priority among the plurality of candidate cells.

The following describes the above modes with reference to specific examples.

It is assumed that the terminal device can measure the following frequency points:

The frequency point F1 is the strongest Cell1, the signal quality of the measured SSB is 1dbm higher than the second signal threshold (SSB RSRP) of the corresponding LP-WUS coverage range, and the frequency priority is P1;

the frequency point F2 is the strongest Cell2, the signal quality of the measured SSB is 4dbm higher than the second signal threshold of the corresponding LP-WUS coverage range, and the frequency priority is P2;

The frequency point F3 is the strongest Cell3, the signal quality of the measured LP-WUS is 10dbm higher than the first signal threshold of the corresponding LP-WUS coverage range, and the frequency priority is P3;

And the frequency point F4 is the strongest Cell4, the signal quality of the measured LP-WUS is 15dbm higher than the first signal threshold of the corresponding LP-WUS coverage range, and the frequency priority is P4.

The frequency priority is from high to low in relation to P1> P2> P3> P4, and the cells satisfy the S criterion.

In the mode 1, the Cell higher than the first threshold, that is, the Cell4 where the first difference is largest, is preferentially selected regardless of the frequency priority.

In the manner 2, the candidate Cell4 with the lowest frequency priority (assuming that the priority of P4 is the lowest among the priorities that can be configured by the protocol) is excluded, and then the Cell with the highest frequency priority above the first threshold, that is, the Cell3 with the first largest difference, is selected. In mode 2, the cell on the frequency point with the lowest frequency priority may be loaded higher, and the network device does not currently expect the terminal device to access the cell and configure the LP-WUS.

In manner 3, cells with signal quality above a first threshold and/or a second threshold preset threshold and highest frequency priority are preferentially selected. The preset threshold is assumed to be 3dBm, and at the moment, the Cell2 needs to be selected preferentially, and the method can give consideration to the frequency priority and the signal strength, so that the selection of a Cell with lower signal strength is avoided, and the situation that the terminal equipment detects that the signal of the LP-WUS shakes to cause frequent entering and exiting of a low-power consumption state of the application LP-WUS is avoided.

Specifically, for cells with the same frequency priority, a cell with the largest first difference and/or second difference is preferentially selected.

For terminal equipment in idle state or inactive state, the selected target cell may reside, and then the target cell may be accessed.

And for the terminal equipment in the connected state, the terminal equipment can be switched to the target cell by a cell switching mode, or can be accessed to the target cell by a cell selection mode or a cell reselection mode after the connection is released from the source service cell.

The procedure of accessing the target cell described above is described in connection with different embodiments.

Embodiment 1, the terminal device is in an idle state or inactive state.

Referring to fig. 2, in step 201, the terminal device measures the signal quality of LP-WUS and/or the signal quality of SSB.

In a specific embodiment, the terminal device may measure the signal quality of the SSB in both the cells where LP-WUS is not applied and the cells where LP-WUS is applied.

In another embodiment, the terminal device may measure the signal quality of the SSB in a cell where the LP-WUS is not applied and the signal quality of the LP-WUS in a cell where the LP-WUS is applied.

In step 202, the terminal device determines a target cell based on one or more of a first difference in signal quality of the LP-WUS and the first signal threshold, a second difference in signal quality of the SSB and the second signal threshold, and a frequency priority of the cell. The terminal equipment accesses the determined target cell through cell selection and/or cell reselection.

Specifically, the terminal device may obtain the first signal threshold and/or the second signal threshold by receiving system information blocks of the plurality of candidate cells. The system information block carries the first signal threshold and/or the second signal threshold.

Further, the first signal threshold and the second signal threshold corresponding to different candidate cells are different from or the same as each other.

In step 203, the terminal device sends an access request to the network device. To request access to the target cell.

Further, the access request includes a first cause indicating a configuration of the LP-WUS. That is, the terminal device may request configuration of the LP-WUS when accessing the target cell.

In this embodiment, since the candidate cell has information about LP-WUS, such as permission request LP-WUS, in the system message, the terminal device can know that the newly selected target cell supports LP-WUS. In the access procedure of the new target cell, the terminal device indicates to the target cell to request the LP-WUS configuration.

For terminal devices in the inactive state, the request for LP-WUS configuration may be indicated by a recovery cause in a radio resource control (Radio Resource Control, RRC) recovery request, and in particular, the first cause may be carried with idle bits in the existing recovery cause.

For terminal devices in idle state, the need to configure the LP-WUS may be indicated by the establishment cause in the RRC establishment request after entering the new cell. In particular, the first cause may be carried with idle bits in the existing establishment cause.

In step 204, the terminal device sends a first request to the network device. The first request is for requesting configuration of the LP-WUS. That is, the terminal device may request configuration of the LP-WUS after accessing the target cell.

It should be noted that, the terminal device may optionally carry the first reason in the access request, or send the first request, which is not limited by the present application.

After learning of the first cause or first request of the terminal device, the target cell may configure the terminal device with LP-WUS related parameters, such as a packet or an identity of the LP-WUS to be detected, a time-frequency resource location of the LP-WUS to be detected, etc. After learning the configuration of the LP-WUS, the terminal device may enter a low power consumption state after entering an idle state or an inactive state, and detect the LP-WUS to learn whether there is a paging requirement. The target cell may also configure the LP-WUS parameters of the application in the connected state for the terminal device, such as an offset (e.g. 2 slots earlier than the start time of drx-onDuration) relative to the start time of discontinuous reception of the configuration (start time of drx-onDuration), a packet or an identification of the LP-WUS to be detected, etc. It should be noted that, there may be a difference between the LP-WUS parameters applicable in the connection state and the LP-WUS parameters applicable in the idle state, for example, the LP-WUS parameters applicable in the idle state may be an offset relative to the paging occasion, the LP-WUS parameters applicable in the connection state may be an offset relative to the starting time of discontinuous reception, and the packets or identifiers of the terminal devices in the LP-WUS parameters applicable in the idle state may be different or the same as those in the LP-WUS parameters applicable in the connection state.

Further, the terminal device may send the above access request or the first request when the signal quality of the accessed cell is in a static state or the variation of the signal quality of the accessed cell is lower than a preset threshold (e.g. the maximum variation of the signal quality of the serving cell measured within 10 minutes is lower than 6 db).

Example 2 and example 2 are variations of example 1.

In this embodiment, the terminal device is in a connected state, and the terminal device may execute step 204, where the terminal device sends a first request to the network device. The first request is for requesting configuration of the LP-WUS. That is, the terminal device may request configuration of the LP-WUS after accessing the target cell.

Alternatively, the terminal device may perform step 202 and step 203 to access the target cell, entering the connected state from the idle/inactive state.

It should be noted that the terminal device may also select and access the target cell in the existing manner, which is not limited by the present application.

Embodiment 3, the terminal device is in a connected state.

The connected terminal device expects to configure LP-WUS, and if the accessed serving cell does not support LP-WUS or is not suitable for using LP-WUS, the serving cell, i.e. the primary cell (PRIMARY CELL, pcell), can handover the terminal device to a cell supporting LP-WUS.

Referring to fig. 3, in step 301, a terminal device sends a first request to a network device. To request configuration of LP-WUS.

Specifically, the terminal device may send a first request for configuring LP-WUS to the primary cell in a case that the terminal device is in a stationary state or the variation of the signal quality of the accessed cell is lower than a preset threshold (e.g. the maximum variation of the signal quality of the serving cell measured within 10 minutes is lower than 6 db).

Further, in step 302, the terminal device measures the signal quality of the LP-WUS and/or the signal quality of the SSB.

In step 303, the terminal device reports the signal quality of LP-WUS and/or the signal quality of SSB to the source network device.

Specifically, the present invention relates to a method for manufacturing a semiconductor device. The terminal device reports a measurement report to the source network device, wherein the measurement report comprises the signal quality of the LP-WUS and/or the signal quality of the SSB.

Further, in step 304, the source network device determines the target cell based on one or more of a first difference in signal quality of the LP-WUS and the first signal threshold, a second difference in signal quality of the SSB and the second signal threshold, and a frequency priority of the cell (taking into account cell load).

Further, step 305 is performed next, or steps 306 to 309 are performed.

In step 305, the source network device initiates a handover procedure to the target network device. To switch the terminal device to the target cell. While the terminal device may be configured with the LP-WUS parameters applied in the target cell in the handover command.

The terminal device accesses the target cell according to the handover command, and may apply the LP-WUS configured by the target cell in the connected state, or may release the connection with the terminal device after the target cell, so as to enable the terminal device to apply the LP-WUS in the idle state or the inactive state.

In step 306, the source network device sends a second request to the target network device requesting that the target network device configure the LP-WUS for the terminal device.

In step 307, the source network device receives a response returned by the target network device containing the target cell configuration LP-WUS.

In step 308, the source network device sends RRC release signaling to the terminal device. The terminal device enters an idle state or an inactive state. The RRC release signaling includes LP-WUS parameters configured by the target cell for the terminal device.

In step 309, the terminal device performs cell selection and/or cell reselection to access the target cell and apply LP-WUS in the target cell.

It should be noted that the serial numbers of the steps in the present embodiment do not represent a limitation on the execution sequence of the steps.

In one non-limiting embodiment, the terminal devices in a connected state also have a need to configure the LP-WUS. It is desirable that the source network device interact with other network devices via an inter-network device interface (e.g., an inter-base station interface). In particular, the source network device may send first information to the target network device, the first information comprising whether to configure the LP-WUS parameters, so that the target network device configures the LP-WUS parameters for the terminal device.

Specifically, the source network device may also forward to the terminal device LP-WUS parameters configured by the target network device for the terminal device.

The following description is made with reference to specific examples.

Embodiment 4, the source network device indicates to the target network device whether to configure the LP-WUS parameters at the time of a cell handover request.

In step 401, the target network device sends first capability information to the source network device. The first capability information indicates whether LP-WUS is supported. In particular, it may be indicated whether one or more serving cells of the target network device, i.e. a plurality of neighbor cells of the Pcell, support LP-WUS.

Further, in step 402, the target network device sends the first signal threshold and/or the second signal threshold to the source network device.

In this embodiment, it is assumed that the mobile state of the terminal device is an almost stationary, or low mobile state, and because the LP-WUS is to be configured, not only the cell is to support the LP-WUS, but also the channel state of the terminal device in the cell is to meet a certain threshold, the PCell needs to know whether the surrounding cell supports the LP-WUS and the threshold that the signal quality measured by the terminal device needs to meet. If the cell supports LP-WUS and the channel conditions of the cell measured by the terminal device are good, the terminal device may be handed over to the cell to configure the LP-WUS for the terminal device.

Specifically, the target network device as well as other network devices surrounding the source network device communicate first capability information, i.e., capability information whether LP-WUS is supported, through the inter-network device interface. For example, the base station 1 indicates to the base station 2 whether or not the own cell under jurisdiction supports the capability information of LP-WUS. In particular, the first capability information may be embedded in existing inter-base station interface signaling, such as signaling NODE CONFIGURATION UPDATE, or signaling XN SETUP REQUEST. The source network device can acquire the capability information of whether the cells managed by the adjacent network device support the LP-WUS, and when the terminal device has the requirement of configuring the LP-WUS, the terminal device can be switched to the cells supporting the LP-WUS.

Specifically, after the Pcell acquires which neighbor cells support the LP-WUS, a measurement task is configured for the terminal device, so that the terminal device measures the frequency points where the neighbor cells are located, and further obtains the signal quality of the cells on the frequency points. In particular, the signal quality of the LP-WUS and/or the signal quality of the SSB may be mentioned.

Further, in step 403, the terminal device reports the signal quality of LP-WUS and/or the signal quality of SSB to the source network device. The signal quality of the LP-WUS and/or the signal quality of the SSB may be carried in the measurement report.

Further, in step 404, the source network device determines the target cell based on one or more of a first difference in signal quality of the LP-WUS and the first signal threshold, a second difference in signal quality of the SSB and the second signal threshold, and a frequency priority of the cell (reference cell load).

Specifically, after the terminal device reports the measurement report, the source network device selects a cell (exceeding the first signal threshold or exceeding the second signal threshold) with better signal quality measured by the terminal device to switch, so that after the terminal device enters a new cell, the LP-WUS can be configured.

Further, in step 405, the source network device sends a handover request to the target network device, the handover request carrying first information, i.e. whether to configure the LP-WUS parameter.

Further, in step 406, the source network device receives a handover request acknowledgement from the target network device, the source base station sends a handover command to the terminal device, and the terminal device switches to the target network device.

In case the first information in the handover request indicates to configure the LP-WUS parameter, after the terminal device accesses the target network device, the target network device configures the LP-WUS parameter for the terminal device, e.g. a packet or an identity of the LP-WUS to be detected, a time-frequency resource location of the LP-WUS to be detected, etc. Or the target network device may configure the LP-WUS directly in the handover request acknowledgement so that the terminal device may apply the LP-WUS immediately after handover to the target cell. The handover request acknowledgement may include the LP-WUS of the application in the connected state and/or the LP-WUS of the application in the idle/inactive state.

In embodiment 5, the source network device obtains the LP-WUS parameters of the target network device through the interface between network devices, and forwards the LP-WUS parameters of the target network device to the terminal device.

In this embodiment, the terminal device needs to configure LP-WUS at the current PCell, and there is no other service requirement, but the current PCell is not suitable for configuring LP-WUS for the terminal device.

In this case, the PCell may request an appropriate target cell for terminal equipment configuration LP-WUS through the inter-base station interface. Specifically, the specific process of PCell selection of a suitable target cell may refer to steps 401 to 404 in the foregoing embodiments, and other embodiments described above, which are not described herein. After the PCell obtains LP-WUS configured by one or more target cells for the terminal device, the terminal device may be simultaneously indicated with LP-WUS parameters configured by one or more target cells for the terminal device when releasing the connection with the terminal device, and after the terminal device enters an idle state or a non-active state, the LP-WUS configured by the cell is applied according to the resident cell.

Referring to fig. 5, in step 501, the source network device sends a third request to the target network device. The third request is for requesting configuration of the LP-WUS.

Specifically, in response to the first request, the target network device configures the terminal device with the LP-WUS parameters.

Further, in step 502, the target network device transmits the LP-WUS parameters to the source network device. Wherein the first request and the LP-WUS parameters may be transmitted over an inter-network device interface.

Further, in step 503, the source network device sends RRC release signaling to the terminal device. The RRC release signaling includes LP-WUS parameters configured by the target network device.

Specifically, the RRC release signaling may carry LP-WUS parameters corresponding to one or more target cells, so that when the terminal device enters an idle state or an inactive state and accesses any one of the multiple target cells, the LP-WUS corresponding to the accessed target cell is applied.

Further, the RRC release signaling may also include the cell, frequency information to which the LP-WUS parameter belongs. If there is no LP-WUS associated cell, frequency information, then the default is the LP-WUS of the PCell configuration.

After receiving the RRC release signaling, the terminal device stores the relevant configuration. And in step 504 cell selection or cell reselection is performed. The terminal device may prefer a cell configuring the LP-WUS parameters as a camping cell. Of course, the cell residence needs to be selected to meet other conditions, such as the strongest signal quality at the frequency point, the signal quality meeting a preset threshold, etc.

Further, if the PCell configures the LP-WUS parameters of the terminal device in one or more cells through RRC release signaling, the terminal device may perform cell selection/reselection in an existing manner after entering an idle state or an inactive state, and if it can camp on the cell configuring the LP-WUS, the LP-WUS is detected in the cell, and enters a low power consumption state.

In one non-limiting embodiment, in addition to the foregoing case that the terminal device may actively send the first request or carry the first reason in the access request to request the LP-WUS configuration, the network device may also guide the terminal device to perform the LP-WUS configuration through the downlink information.

Embodiment 6, the network device informs the terminal device that the cell/frequency information of LP-WUS can be configured through the second information.

In step 601, the network device sends second information to the terminal device. The second information includes a first frequency supporting LP-WUS. That is, there is a cell supporting LP-WUS on the first frequency.

Specifically, the second information is carried in a system information block (System Information Block, SIB).

Further, the second information also includes an identity of a first cell or physical cell identity (PHYSICAL CELL IDENTIFIER, PCI Range (PCI Range) supporting the LP-WUS on the first frequency.

In step 602, the terminal device performs cell selection or cell measurement according to the second information. In particular, the terminal device may measure a first cell on a first frequency.

Further, in step 603, in response to the signal quality of the first cell exceeding the first signal threshold or exceeding the second signal threshold, the terminal device determines the frequency priority of the first frequency to which the first cell belongs as the highest priority.

Specifically, the first signal threshold is a threshold requirement of signal quality of LP-WUS, and the second signal threshold is a threshold requirement of signal quality of SSB. The specific signal detection and comparison process may refer to the foregoing embodiments, and will not be described herein.

In this embodiment, in order to enable the terminal device to quickly obtain the cell information capable of configuring the LP-WUS, a new parameter (i.e. a second message) may be configured in the system message of the serving cell, to indicate which frequency points the LP-WUS is configured on, for example, to specify that the cells supporting the LP-WUS exist on the first frequency F1 and the first frequency F2. After the terminal device obtains this information, if it is expected to configure the LP-WUS, it may preferentially detect the neighbors on the first frequency F1 and the first frequency F2 in order to find a cell that can provide the LP-WUS configuration for camping.

Accordingly, if the terminal device finds a cell that can provide LP-WUS on the first frequency F1 and the terminal device finds that LP-WUS can be applied in the cell through signal quality detection, such as exceeding the first signal threshold or exceeding the second signal threshold, the terminal device still regards the frequency priority of the frequency point as the highest priority even when the frequency priority of the frequency point is not the highest priority, so that LP-WUS can be applied in the cell. Then if it is found that the LP-WUS cannot continue to be applied in the cell due to the movement of the terminal device, the terminal device no longer considers the frequency priority of the frequency point as the highest priority.

Further, for the specific process of determining the target cell by the subsequent terminal device according to the frequency priority of the first frequency and the like, and performing LP-WUS configuration, reference may be made to the foregoing embodiments, which are not described herein in detail.

It should be noted that the serial numbers of the steps in the present embodiment do not represent a limitation on the execution sequence of the steps.
