Communication method and apparatus

Abstract

A communication method and apparatus, which is capable of disabling, for a first-type terminal, the function of monitoring a wake-up signal in a serving cell, thereby avoiding invalid monitoring for the wake-up signal by the first-type terminal. The method comprises: in configuration information of a wake-up signal, omitting a first configuration related to a first-type terminal, so as to implicitly indicate that an LP-WUS function of the first-type terminal is disabled. The omitted configuration may be, for example, a configuration of an LP-SS, an activation / deactivation threshold of the wake-up signal based on LP-SS measurement, or a configuration of the wake-up signal of the first-type terminal. After receiving the configuration information in which the first configuration is omitted, a terminal can determine, on the basis of the configuration information, that the serving cell does not support the first-type terminal to monitor a wake-up signal. Compared with the solution in which explicit signaling is used to indicate that a serving cell does not support a first-type terminal to monitor a wake-up signal, the solution in which the serving cell not supporting the first-type terminal to monitor the wake-up signal is indicated by means of omitting, in a configuration related to the wake-up signal, a first configuration related to the first-type terminal can reduce signaling overheads.

Description

Communication method and apparatus

[0001] The present application claims priority to the Chinese patent application No. 202411098042.3, filed on August 9, 2024, and entitled "Communication method and apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the field of communication, in particular to a communication method and apparatus. BACKGROUND

[0003] In order to achieve lower terminal power consumption, a low power wake up signal (LP-WUS) mechanism is currently being studied. Under this mechanism, the receiving circuit of the terminal can be divided into a main circuit (MR) and a low power wake up circuit (LP-WUR). The energy saving logic of the LP-WUS mechanism is that when there is no data / service transmission on the MR, the MR can enter an off or sleep state to greatly reduce the "standby" power consumption of the terminal, while the LP-WUR is turned on for monitoring the LP-WUS. When the LP-WUR receives the LP-WUS, it will wake up the MR for data / service transmission.

[0004] Generally, the LP-WUS can be modulated in an on-off keying (OOK) manner, and correspondingly, the LP-WUR of the terminal receives the LP-WUS in an envelope detection manner; or, the LP-WUS can be modulated in an orthogonal frequency division multiplexing (OFDM) manner, and correspondingly, the LP-WUR of the terminal receives the LP-WUS in a correlation detection manner. Among them, modulating in the OFDM manner can save time domain resources.

[0005] Therefore, in the case of limited network side resources, the network can generate the LP-WUS in the OFDM modulation manner. At this time, the terminal that only supports envelope detection may not be able to receive the LP-WUS. SUMMARY

[0006] The present application provides a communication method and apparatus, which can disable part of the terminals to monitor the wake up signal in the serving cell, thereby avoiding the invalid monitoring of the wake up signal by the part of the terminals.

[0007] In a first aspect, a communication method is provided. The method can be performed by a first terminal, or by a component of the first terminal, such as a processor, a chip, or a chip system of the first terminal, or by a logic module or software that can implement all or part of the function of the first terminal. The method is described below with the first terminal as an example, and includes: receiving first configuration information, the first configuration information being used to indicate a configuration of a wake-up signal, the first configuration information being default first configuration related to a first type of terminal; and determining, according to the first configuration information, that a serving cell does not support the first type of terminal to monitor the wake-up signal.

[0008] Based on the scheme, the network side can disable the function of the first type of terminal to monitor the wake-up signal in the serving cell, thus avoiding invalid monitoring of the wake-up signal by the terminal. In addition, the network side can not need to consider the problem of the multiple types of terminals monitoring the wake-up signal, thus reducing the implementation complexity. Furthermore, compared with the scheme of indicating that the serving cell / serving frequency point does not support the first type of terminal to monitor the wake-up signal through explicit signaling, the scheme of indicating that the serving cell / serving frequency point does not support the first type of terminal to monitor the wake-up signal by defaulting the first configuration related to the first type of terminal in the related configuration of the wake-up signal can reduce the signaling load and overhead.

[0009] In a possible design, the first type of terminal supports envelope detection and does not support correlation detection.

[0010] Based on the possible design, since the function of the first type of terminal to monitor the wake-up signal is disabled, the first type of terminal that does not support correlation detection can not need to consider transmitting the wake-up signal through OFDM modulation, thus reducing the time domain resource occupancy rate and saving time domain resources compared with transmitting the wake-up signal through OOK modulation.

[0011] In a possible design, the first configuration is a configuration of a low-power synchronization signal (LP-SS).

[0012] Based on the possible design, since the LP-WUR of the terminal can perform synchronization and / or measurement by receiving an SSB or an LP-SS, for the first type of terminal, the first type of terminal can only receive an LP-SS based on OOK modulation to perform synchronization and / or measurement, and thus, in the case of defaulting the configuration of the LP-SS in the related configuration of the wake-up signal, the first type of terminal cannot receive the LP-SS. Since the first type of terminal also cannot receive the SSB, it can be considered that the first type of terminal cannot perform synchronization and / or measurement through the LP-WUR. In the case that the first type of terminal cannot perform synchronization and / or measurement, the first type of terminal cannot monitor the wake-up signal, and thus it can be considered that the current serving cell does not support the first type of terminal to monitor the wake-up signal. That is, the current serving cell can implicitly indicate that it does not support the first type of terminal to monitor the wake-up signal by defaulting the configuration of the LP-SS.

[0013] In a possible design, the configuration of the LP-SS includes at least one of the following: a LP-SS period, a LP-SS modulation mode, or a time-domain and frequency-domain resource location of the LP-SS.

[0014] In a possible design, the first configuration is a first threshold, and the first threshold includes an activation threshold and / or a deactivation threshold of the wake-up signal based on the LP-SS measurement.

[0015] Based on the possible design, since the LP-WUR of the terminal can perform measurement and / or synchronization by receiving the SSB or the LP-SS, for the first type of terminal, which cannot receive the SSB, i.e., the first type of terminal can only receive the LP-SS based on the OOK modulation to perform synchronization and / or measurement, in the case where the activation / deactivation threshold of the wake-up signal based on the LP-SS measurement is defaulted in the related configuration of the wake-up signal, the first type of terminal cannot determine the timing of activating / deactivating the wake-up signal based on the LP-SS measurement, and thus cannot determine whether to monitor or not to monitor the wake-up signal. Since the first type of terminal also cannot receive the SSB, it can be considered that the first type of terminal cannot monitor the wake-up signal, and thus it can be considered that the current serving cell does not support the first type of terminal to monitor the wake-up signal. That is, the current serving cell not supporting the first type of terminal to monitor the wake-up signal can be implicitly indicated by defaulting the activation / deactivation threshold based on the LP-SS measurement.

[0016] In a possible design, the first configuration information includes the configuration of the wake-up signal of the second type of terminal, and the first configuration is the configuration of the wake-up signal of the first type of terminal.

[0017] Based on the possible design, in the case where the network side respectively configures the wake-up signal for the first type of terminal and the second type of terminal, if the network side defaults the configuration of the wake-up signal of the first type of terminal, the first type of terminal cannot obtain the related information of the wake-up signal, and thus cannot monitor the wake-up signal, and it can be considered that the current serving cell does not support the first type of terminal to monitor the wake-up signal. That is, the current serving cell not supporting the first type of terminal to monitor the wake-up signal can be implicitly indicated by defaulting the configuration of the wake-up signal of the first type of terminal.

[0018] In a possible design, the second type of terminal supports the related detection.

[0019] In one possible design, the first type of terminal is not supported to monitor the wake-up signal, including at least one of the following: the first type of terminal is not allowed to monitor the wake-up signal, the first type of terminal is not supported to be provided with the wake-up signal, the provided wake-up signal does not support / allow the first type of terminal to monitor, the provided wake-up signal cannot be demodulated by the first type of terminal, the first type of terminal is not supported / allowed to use the wake-up signal, the first type of terminal is disabled for the wake-up signal, the first type of terminal is disabled to monitor the wake-up signal, the function of the first type of terminal to monitor the wake-up signal is disabled, or the first receiver of the first type of terminal is disabled.

[0020] In a second aspect, a communication method is provided, which can be performed by a first terminal, or by a component of the first terminal, such as a processor, a chip, or a chip system of the first terminal, or by a logic module or software that can implement all or part of the function of the first terminal. The following describes the method by taking the first terminal as an example, which includes: performing cell reselection evaluation in a case where it is determined that a serving cell does not support the first terminal to monitor a wake-up signal. The cell reselection evaluation includes at least one of the following: performing cell reselection evaluation according to at least one of the following: a cell reselection priority of the updated serving cell, a cell reselection priority of a frequency on which the serving cell is located, or a cell reselection priority of a frequency on which a neighbor cell is located; or performing neighbor cell measurement in a case where a signal quality of the serving cell is greater than a first threshold; or performing cell reselection evaluation according to a first frequency list, and a cell on a frequency in the first frequency list supports the first terminal to monitor the wake-up signal.

[0021] Based on the scheme, in a case where the serving cell does not support a certain terminal to monitor the wake-up signal, the terminal can adjust the cell reselection priority, such as reducing the cell reselection priority of the serving cell, a frequency on which the serving cell is located, or a frequency on which a cell that does not support the terminal to monitor the wake-up signal is located, or increasing the cell reselection priority of a frequency on which a neighbor cell that supports the terminal to monitor the wake-up signal is located. Thus, in cell reselection, high-priority neighbor cell reselection can be triggered, and the terminal can be reselected to a cell that supports the terminal to monitor the wake-up signal as much as possible, thereby achieving terminal energy saving.

[0022] Alternatively, in a case where the serving cell does not support the terminal to monitor the wake-up signal, even if the signal quality of the serving cell is good, the terminal can still start neighbor cell measurement, such as starting neighbor cell measurement on a frequency that supports the terminal to monitor the wake-up signal. Thus, in a case where there is a neighbor cell that meets the cell reselection evaluation criterion, the terminal can be reselected to the neighbor cell, and continues to monitor the wake-up signal in the neighbor cell, thereby achieving terminal energy saving.

[0023] Alternatively, in a case where the serving cell does not support the terminal to monitor the wake-up signal, a frequency point list supporting the terminal to monitor the wake-up signal can be configured for the terminal, so that the terminal can perform measurement on the frequency points in the frequency point list, and thus can reselect to a cell satisfying the cell reselection evaluation criterion on the frequency point based on the measurement result. Since the cell on the frequency point supports the terminal to monitor the wake-up signal, after the terminal reselects to the cell on the frequency point, the terminal can monitor the wake-up signal in the cell, thereby achieving terminal energy saving.

[0024] In a possible design, the method further includes: receiving first information, the first information indicating a cell reselection priority of a first frequency point, the first frequency point being a frequency point where the serving cell is located; updating the cell reselection priority of the first frequency point to a first priority, or updating the cell reselection priority of the serving cell to the first priority. The first priority is lower than the cell reselection priority of the frequency point where the first cell is located, or the first priority is the lowest priority. The first cell is a neighbor cell supporting the first terminal to monitor the wake-up signal.

[0025] Based on the possible design, in a case where the serving cell does not support a certain terminal to monitor the wake-up signal, the terminal can update the cell reselection priority of the serving cell or the serving frequency point to the lowest priority, or to a priority lower than the priority of the frequency point where the cell supporting the terminal to monitor the wake-up signal is located. Therefore, when performing cell reselection subsequently, since the priority of the serving cell or the serving frequency point is low and the cell reselection priority of the frequency point where the cell supporting the terminal to monitor the wake-up signal is located is high, the terminal can trigger high-priority neighbor cell reselection, so as to reselect to the cell supporting the terminal to monitor the wake-up signal as much as possible, thereby achieving energy saving of the terminal.

[0026] In a possible design, the method further includes: receiving second information, the second information indicating a cell reselection priority of a second frequency point, the second frequency point being a frequency point where the first cell is located, and the first cell being a neighbor cell supporting the first terminal to monitor the wake-up signal; updating the cell reselection priority of the second frequency point to a second priority. In a case where the second frequency point is different from the frequency point where the serving cell is located, the second priority is higher than the cell reselection priority of the frequency point where the serving cell is located, or the second priority is the highest priority. Alternatively, in a case where the second frequency point is the same as the frequency point where the serving cell is located, the second priority is higher than the cell reselection priority of the serving cell, or the second priority is the highest priority.

[0027] Based on the possible design, in a case where the serving cell does not support a terminal to monitor the wake-up signal, the terminal can update a cell reselection priority of a cell at a frequency point where a cell supporting the terminal to monitor the wake-up signal to a highest priority, or to a priority higher than a cell reselection priority of the serving cell or a frequency point of the serving cell. Therefore, in subsequent cell reselection, since the priority of the serving cell or the frequency point of the serving cell is low, and the priority of the cell at the frequency point where the cell supporting the terminal to monitor the wake-up signal is high, the terminal can trigger high-priority neighbor cell reselection, so as to reselect the cell supporting the terminal to monitor the wake-up signal as much as possible, thereby realizing energy saving of the terminal.

[0028] In a possible design, the method further includes: receiving third information, the third information indicating a cell reselection priority of a third frequency point, the third frequency point being a frequency point where a second cell is located, the second cell being a neighbor cell that does not support the first terminal to monitor the wake-up signal; and updating the cell reselection priority of the third frequency point to a third priority. The third priority is lower than a cell reselection priority of a frequency point where the first cell is located, or the third priority is a lowest priority. The first cell is a neighbor cell that supports the first terminal to monitor the wake-up signal.

[0029] Based on the possible design, in a case where the serving cell does not support a terminal to monitor the wake-up signal, the terminal can update a cell reselection priority of a cell at a frequency point where a cell supporting the terminal to monitor the wake-up signal to a highest priority, or to a priority higher than a cell reselection priority of the serving cell or a frequency point of the serving cell. Therefore, in subsequent cell reselection, since the priority of the serving cell or the frequency point of the serving cell is low, and the priority of the cell at the frequency point where the cell supporting the terminal to monitor the wake-up signal is high, the terminal can trigger high-priority neighbor cell reselection, so as to reselect the cell supporting the terminal to monitor the wake-up signal as much as possible, thereby realizing energy saving of the terminal.

[0030] In a possible design, the first cell is a cell in a first cell list, and the first cell list includes at least one of a same-frequency neighbor cell list, a different-frequency neighbor cell list, or a different-system neighbor cell list of the serving cell.

[0031] In a possible design, the method further includes: receiving fourth information, the fourth information indicating at least one of an updated cell reselection priority of the serving cell, a cell reselection priority of a frequency point where the serving cell is located, or a cell reselection priority of a frequency point where a neighbor cell is located.

[0032] In a possible design, in a case where the signal quality of the serving cell is greater than a first threshold, performing neighbor cell measurement includes: in a case where the signal quality of the serving cell is greater than the first threshold, performing same-frequency measurement on a same-frequency neighbor cell of the serving cell.

[0033] In one possible design, the performing the neighbor cell measurement includes: performing inter-frequency or inter-RAT frequency measurement for a neighbor cell whose cell reselection priority is lower than or equal to a cell reselection priority of the serving cell, and a neighbor cell whose cell reselection priority is lower than a cell reselection priority of the serving cell, if the signal quality of the serving cell is greater than the first threshold.

[0034] In one possible design, the performing the neighbor cell measurement includes: performing measurement for a neighbor cell that supports the wake-up signal for the first terminal.

[0035] In one possible design, the method further includes: receiving fifth information, the fifth information including a first frequency point list.

[0036] In one possible design, the fifth information further includes a second frequency point list and / or a third frequency point list; a cell on a frequency point in the second frequency point list supports the wake-up signal, and a cell on a frequency point in the third frequency point list does not support the wake-up signal for the first terminal.

[0037] In one possible design, the first terminal is a first type of terminal.

[0038] In one possible design, the first type of terminal supports envelope detection and does not support correlation detection.

[0039] In a third aspect, a communication method is provided. The method can be performed by a second RAN node, or by a component of the second RAN node, e.g., a processor, a chip, or a chip system of the second RAN node, or by a logic module or software that can implement all or part of the functions of the second RAN node. For example, the second RAN node can be a DU. The method includes: receiving a paging message from a first radio access network (RAN) node, the paging message including indication information indicating a type of a terminal being paged or a type of a first receiver supported by the terminal being paged, the first receiver being used to monitor a wake-up signal; and transmitting or not transmitting the wake-up signal in a first cell according to the type of the terminal or the type of the first receiver supported by the terminal.

[0040] Based on the scheme, the DU can determine whether to send or not to send the wake-up signal in the cell based on the type of the terminal being paged or the type of the first receiver supported by the terminal. For example, in the case that the cell supports the wake-up signal but does not support the first type of terminal to monitor the wake-up signal, if the first type of terminal is paged, the DU can not send the wake-up signal in the cell, because the cell does not support the first type of terminal to monitor the wake-up signal, at this time, even if the DU sends the wake-up signal in the cell, the first type of terminal in the cell cannot monitor the wake-up signal, so the main receiver of the first type of terminal cannot be woken up, resulting in waste of network side resources. In addition, if the DU sends the wake-up signal in the cell, it will wake up the second type of terminal belonging to the same terminal group as the paged terminal, unnecessarily waking up the second type of terminal, increasing the false alarm probability of the second type of terminal, and reducing the energy saving gain.

[0041] That is, in the case that a certain cell supports the wake-up signal but does not support the first type of terminal to monitor the wake-up signal, if the first type of terminal is paged, the DU does not send the wake-up signal in the cell, which can save network side resources and avoid resource waste. In addition, it can also reduce the false alarm probability of part of the second type of terminal and increase the energy saving gain of the second type of terminal.

[0042] In a possible design, in the case that the first type of terminal does not support monitoring the wake-up signal, if the type of the terminal or the type of the first receiver supported by the terminal is the first type, the wake-up signal is not sent in the first cell; or if the type of the terminal or the type of the first receiver supported by the terminal is the second type, the wake-up signal is sent in the first cell.

[0043] Based on the possible design, in the case that a certain cell supports the wake-up signal but does not support the first type of terminal to monitor the wake-up signal, if the second type of terminal is paged, the DU sends the wake-up signal in the cell. Since the cell does not support the first type of terminal to monitor the wake-up signal, the wake-up signal can be generated according to the above manner two, so that the wake-up signal cannot be received by the first type of terminal in the cell, that is, the second type of terminal can be accurately woken up, and the first type of terminal is not false alarmed.

[0044] In a possible design, in the case that the first cell supports the wake-up signal and supports the first type of terminal to monitor the wake-up signal, if the type of the terminal or the type of the first receiver supported by the terminal is the first type or the second type, the wake-up signal is sent in the first cell.

[0045] In a possible design, the first type of terminal or the first receiver supports envelope detection and does not support correlation detection; the second type of terminal or the first receiver supports correlation detection.

[0046] In a fourth aspect, a communication method is provided, which can be performed by a second RAN node, by a component of the second RAN node, e.g., a processor, a chip, or a chip system, etc. of the second RAN node, and by a logic module or software that can implement all or part of the functions of the second RAN node. The method is described below by taking the second RAN node as an example, and the method comprises: sending first information to a first radio access network (RAN) node, the first information indicating whether at least one cell supports a first type of terminal monitoring a wake-up signal, and / or whether a second type of terminal supports monitoring a wake-up signal; and receiving a paging message from the first RAN node, the paging message being used to page a third type of terminal in cells in a paging cell list, the third type of terminal being the first type of terminal or the second type of terminal. In a case where the first information indicates that the first cell does not support the third type of terminal monitoring a wake-up signal, the paging cell list does not include the first cell. Exemplarily, the second RAN node can be a DU, and the first RAN node can be a CU.

[0047] Based on the scheme, the CU can reasonably adjust the paging cell list based on the enabling condition of the wake-up signal of the at least one cell / frequency point reported by the DU. For example, in a case where a certain cell does not support a certain type of terminal monitoring a wake-up signal, if the terminal of the type is paged, the CU can delete the cell from the paging cell list, so that the DU also does not send a wake-up signal in the cell. This is because: the cell does not support the type of terminal monitoring a wake-up signal, even if the DU sends a wake-up signal in the cell, the terminal of the type in the cell cannot monitor the wake-up signal, so the main receiver of the terminal of the type cannot be woken up, resulting in waste of network side resources. In addition, if the DU sends a wake-up signal in the cell, other types of terminals belonging to the same terminal group as the paged terminal (the cell supports the other types of terminals monitoring a wake-up signal) will be woken up, which unnecessarily wakes up the other types of terminals, increases the false alarm probability of the other types of terminals, and reduces the energy saving gain. That is, based on the above scheme, network side resources can be saved, and resource waste can be avoided. In addition, the false alarm probability of part of the terminals can be reduced, and the energy saving gain of the part of the terminals can be increased.

[0048] In a fifth aspect, a communication method is provided. The method can be performed by a first RAN node, by a component of the first RAN node, such as a processor, a chip, or a chip system of the first RAN node, or by a logic module or software that can implement all or part of the functions of the first RAN node. The method is described below with reference to the first RAN node. The method includes: receiving first information from a second RAN node, the first information indicating whether at least one cell supports a first type of terminal monitoring a wake-up signal, and / or whether a second type of terminal supports monitoring a wake-up signal; and sending a paging message to the second RAN node, the paging message being used to page a third type of terminal in cells in a paging cell list, the third type of terminal being the first type of terminal or the second type of terminal. In a case where the first information indicates that a first cell does not support the third type of terminal monitoring a wake-up signal, the paging cell list does not include the first cell. The technical effects brought by the fifth aspect can refer to the technical effects brought by the fourth aspect, and will not be described herein.

[0049] In combination with the fourth aspect or the fifth aspect, in a possible design, the first type of terminal supports envelope detection and does not support correlation detection; and the second type of terminal supports correlation detection.

[0089] In order to facilitate the understanding of the technical scheme of the embodiments of the present application, first, a brief introduction of the related technology of the present application is given as follows.

[0090] 1. Cell reselection evaluation:

[0091] For example, the cell reselection evaluation can be understood as a process in which the terminal selects a best cell to provide service by monitoring the signal quality of the neighbor cell and the current cell in the radio resource control (RRC) idle state or inactive state. Generally, cell reselection evaluation involves the following aspects:

[0092] 1) Cell reselection priority:

[0093] Generally, the cell reselection priority is in granularity of frequency point. That is, the cell reselection priority of the cell on the same frequency point of the same radio access technology (RAT) is the same, and the cell reselection priorities of different frequency points can be the same or different.

[0094] Exemplarily, the cell reselection priority includes a common priority and a dedicated priority. The common priority can also be referred to as a general priority.

[0095] The common priority is the cell reselection priority effective for all terminals in the cell, which can be configured by the network through the system message of the current cell. The common priority can include a cell reselection priority and a cell reselection sub-priority. The terminal can add the cell reselection priority and the cell reselection sub-priority, and use the added priority as the final cell reselection priority for cell reselection.

[0096] The dedicated priority can be configured by the network through the RRC release (RRCRelease) message, or can be inherited from other systems, without limitation. The dedicated priority can include a subscriber profile ID (SPID), a RAT / frequency selection priority (RFSP), an operator dedicated priority, and the like.

[0097] Exemplarily, generally, the value range of the cell reselection priority is 0-7, and the greater the value is, the higher the priority is. The value range of the cell reselection sub-priority is 0.2, 0.4, 0.6, 0.8, and similarly, the greater the value is, the higher the sub-priority is.

[0098] 2) Cell reselection measurement (also referred to as neighbor cell measurement):

[0099] Exemplarily, the cell reselection measurement can include intra-frequency measurement or inter-frequency / inter-system measurement, and the terminal generally determines whether to start the neighbor cell measurement according to the neighbor cell measurement start condition. For example, the flow of the cell reselection measurement can be as shown in FIG. 1, and reference is made to FIG. 1.

[0100] For intra-frequency measurement:

[0101] If the serving cell satisfies S rxlev S intraSearchP and S qual S intraSearchQ , the terminal can select not to perform the intra-frequency measurement, otherwise, the terminal should perform the intra-frequency measurement.

[0102] wherein, S rxlev and S qualThe signal quality of the current serving cell is measured by the terminal and calculated according to the S criterion formula. intSasearchP and S intraSearchQ This can be understood as the threshold for starting same-frequency measurement. This parameter is configured by the network side, for example, it can be carried in the system information block (SIB)2.

[0103] For measurements of different frequencies or different systems:

[0104] a) For inter-frequency or inter-system frequencies where the cell reselection priority is higher than the cell reselection priority of the current serving cell, the terminal should perform inter-frequency or inter-system measurements with the higher priority.

[0105] b) For inter-frequency cells with a cell reselection priority lower than or equal to the cell reselection priority of the current serving cell, and for inter-RAT frequencies with a cell reselection priority lower than the cell reselection priority of the current serving cell:

[0106] If the serving cell satisfies S rxlev >S nonIntraSearchP And S qual >S nonIntraSearchQ Then the terminal can choose not to perform inter-frequency or inter-RAT frequency (i.e. inter-system) measurements with the same or lower priority;

[0107] Otherwise, the terminal should perform inter-frequency or RAT frequency measurements of the same or lower priority.

[0108] Among them, S nonIntraSearchP and S nonIntraSearchQ This can be understood as the threshold for enabling measurements across different frequencies or systems, and can be configured on the network side, for example, it can be carried in SIB2. For explanations of the other parameters, please refer to the aforementioned descriptions, which will not be repeated here.

[0109] For example, the parameters (or variables) related to cell reselection, their functions, the system messages carrying the parameters, and the fields carrying the parameters can be shown in Table 0 below.

[0110] Table 0

[0111] 3) Community re-selection evaluation criteria:

[0112] After neighbor cell measurement is completed, the terminal can perform an evaluation to determine whether to perform cell reselection to a neighbor cell. For example, the implementation of cell reselection evaluation can be shown in Figure 2. (See Figure 2 for details.)

[0113] For neighboring cells of high-priority frequency points:

[0114] The neighbor cell on the inter-frequency or inter-RAT frequency with higher priority meets S reselectionNR in the time interval T qual > Thresh X,HighQ , or meets S reselectionRAT > Thresh rxlev in the time interval T X,HighP , and the terminal stays in the current serving cell for more than 1 second, the terminal should perform cell reselection to the cell of the inter-frequency or inter-RAT with higher priority than the serving frequency. If there are multiple inter-frequency or inter-RAT neighbor cells meeting the above conditions at the same time, the neighbor cell with the highest signal quality level Rn is selected for cell reselection.

[0115] wherein Thresh X,HighQ and Thresh X,HighP may be understood as the cell reselection threshold of the high priority neighbor cell. X represents the frequency, that is, each frequency corresponds to a cell reselection threshold. Rn will be described in the following embodiments and is not described here.

[0116] For the intra-frequency neighbor cell or the inter-frequency or inter-RAT neighbor cell with the same priority:

[0117] The cell reselection of the same priority is based on the R criterion. If the signal quality of the current serving cell and the same priority neighbor cell meets the S criterion (that is, S rxlev > 0 and S qual > 0), the signal quality level of the cell is calculated, then the cells are sorted according to the cell signal quality level, the cell with the largest or nearly largest cell signal quality level is selected, finally among these cells, the cell with the most beams meeting the requirement of beam signal quality is selected as the best cell, and the cell is said to meet the cell reselection criterion. If the selected best cell meets the cell reselection criterion all the time during the period, and the terminal stays in the current serving cell for more than 1 second, the terminal reselects to the best cell. Exemplarily, the cell signal quality levels Rs and Rn meet: Rs = Q meas,s -Q hyst -Q offsettemp Rn = Q meas,n -Q offset -Q offsettemp

[0118] wherein Q meas,s is the reference signal received power (RSRP) of the serving cell, Q meas,n is the RSRP of the neighbor cell, Q offset is the offset, Q offsettemp is the temporary offset, and Q hyst is the hysteresis value.

[0119] For the neighbor cell of the low priority frequency:

[0120] If ThreshServing,LowQ is broadcasted in the system information of the current serving cell and 1 second has passed since the terminal camps on the current serving cell, the cell reselection of the inter-frequency or inter-system with lower priority than the serving frequency shall be performed in the following case:

[0121] The serving cell satisfies: S qual < ThreshServing,LowQ;

[0122] The neighbor cell on the inter-frequency or inter-system frequency with lower priority satisfies: S reselectionRAT > Thresh qual for the time interval T X,LowQ .

[0123] If ThreshServing,LowP is broadcasted in the system information of the current serving cell, the cell reselection of the inter-frequency or inter-system with lower priority than the serving frequency shall be performed in the following case:

[0124] The serving cell satisfies: S rxlev < ThreshServing,LowP;

[0125] The neighbor cell on the inter-frequency or inter-system frequency with lower priority satisfies: S reselectionRAT > Thresh rclev for the time interval T X,LowP ; and 1 second has passed since the terminal camps on the current serving cell.

[0126] Wherein, ThreshServing,LowQ and ThreshServing,LowP are the cell reselection thresholds of the serving cell, Thresh X,LowQ and Thresh X,LowP are the cell reselection thresholds of the low priority neighbor cell. X represents the frequency, that is, each frequency corresponds to a cell reselection threshold.

[0127] If multiple cells with different priorities satisfy the cell reselection criteria, the reselection of the neighbor cell with higher priority shall be prioritized over the reselection of the neighbor cell with lower priority.

[0128] 2. Low power-wake up signal (LP-WUS) mechanism:

[0129] To achieve lower terminal power consumption, the 3rd generation partnership project (3GPP) is currently studying the LP-WUS mechanism. Under this mechanism, as shown in FIG. 3, the receiving circuit of the terminal on the hardware implementation can be divided into a main circuit / link (MR) and a low power-wake up circuit (LP-WUR). For example, the low power-wake up circuit can also be referred to as a low power receiver. The MR can be used for normal reception of data / service transmission, and the LP-WUR can be used as an auxiliary receiver for detecting and processing LP-WUS.

[0130] The energy-saving logic of the LP-WUS mechanism is that, in the absence of data / service transmission on the MR, the MR can enter a closed or sleep state to greatly reduce the "standby" power consumption of the terminal, while the LP-WUR is turned on to monitor the LP-WUS. When the LP-WUR receives the LP-WUS, the MR will be awakened for data / service transmission.

[0131] For example, in the RRC idle / inactive state, the LP-WUS is used to indicate whether there is a subsequent paging message; in the RRC connected state, the LP-WUS is used to indicate whether there is a subsequent physical downlink control channel (PDCCH) transmission or whether there is a data / service transmission.

[0132] 3. Modulation mode of LP-WUS:

[0133] Generally, the LP-WUS can be modulated in an on-off keying (OOK) mode, and correspondingly, the LP-WUR of the terminal receives the LP-WUS in an envelope detection (or envelope detection) mode; or the LP-WUS can be modulated in an orthogonal frequency division multiplexing (OFDM) mode, and correspondingly, the LP-WUR of the terminal receives the LP-WUS in a correlation detection mode; or the LP-WUS can be modulated in a fusion mode of different modulation modes, for example, the LP-WUS is modulated in an OOK and OFDM fusion mode, and correspondingly, the LP-WUR of the terminal receives the LP-WUS in a correlation detection mode.

[0134] Exemplarily, the LP-WUR receiving the LP-WUS in an envelope detection manner can be regarded as a type of receiver (for example, referred to as a first type of WUR), and the LP-WUR receiving the LP-WUS in a correlation detection manner can be regarded as another type of receiver (for example, referred to as a second type of WUR). Wherein, the first type of WUR and the second type of WUR are relative, and the first type of WUR or the second type of WUR can also be understood as follows:

[0135] The first type of WUR is an OOK receiver, and the second type of WUR is an OFDM receiver; or,

[0136] The first type of WUR is a receiver with only one of two I / Q paths, and the second type of WUR is a receiver with two I / Q paths; or.

[0137] The first type of WUR is a non-coherent receiver, and the second type of WUR is a coherent receiver; or,

[0138] The first type of WUR is a non-coherent receiver with only one of two I / Q paths, and the second type of WUR is a coherent receiver with two I / Q paths; or,

[0139] The first type of WUR receives a signal in an envelope / energy / power / amplitude detection manner, and the second type of WUR receives a signal in a correlation detection manner; or,

[0140] The first type of WUR can / able detect signal energy / power / amplitude, and the second type of WUR can / able detect phase information; or,

[0141] The first type of WUR cannot receive a complex signal (for example, the first type of WUR receives a real signal), and the second type of WUR can receive a complex signal; or,

[0142] The first type of WUR has envelope detection capability or has no correlation detection capability, and the second type of WUR has correlation detection capability; or,

[0143] The first type of WUR supports receiving a signal in an envelope detection manner, and the second type of WUR supports receiving a signal in a correlation detection manner; or,

[0144] The first type of WUR cannot receive an OFDM signal (for example, the first type of WUR receives an OOK signal), and the second type of WUR can receive an OFDM signal.

[0145] Exemplarily, in the embodiments of the present application, the correlation detection can also be understood as phase detection, sequence detection, etc., and the three can be replaced with each other. Herein, the subsequent embodiments will not be repeated.

[0146] For example, the detection performance of the first type of WUR is lower than the detection performance of the second type of WUR. The coverage performance supported by the first type of WUR is lower than the coverage performance supported by the second type of WUR. Generally, if the first type of WUR is used to receive a signal, the coverage performance can be enhanced by a coverage enhancement technology, for example, for the first type of WUR, the coverage performance can be improved by increasing the number of repeated transmissions of the signal.

[0147] 4. OOK modulation:

[0148] OOK modulation uses the presence or absence of a signal to represent bit information. Bit information at the sending end is mapped to at least one time unit through OOK modulation, and one time unit can correspond to one bit. The receiving end can determine the bit information by detecting whether there is a signal in the time unit.

[0149] For example, in an embodiment of the present application, a time unit can generally refer to a unit of time. For example, a time unit can be a radio frame, a subframe, a slot, a mini-slot, an OFDM symbol, a millisecond (ms), or a fraction of a millisecond (e.g., 1 / 32 ms). Alternatively, a time unit is a plurality of slots, a plurality of subframes, a plurality of mini-slots, a plurality of OFDM symbols, a number of milliseconds (ms), or a number of fractions of a millisecond. Wherein, a radio frame can include a plurality of subframes, a subframe can include one or more slots, and a slot can include at least one OFDM symbol. Alternatively, a radio frame can include a plurality of slots, and a slot can include at least one OFDM symbol.

[0150] For example, a time unit with a signal can be understood as a signal amplitude of the time unit being non-zero, such a time unit can also be referred to as an ON time unit, or the time unit being in an ON mode; correspondingly, a time unit without a signal can be understood as a signal amplitude of the time unit being zero, such a time unit can also be referred to as an OFF time unit, or the time unit being in an OFF mode.

[0151] Generally, if a sequence is transmitted on a time unit, there is a signal on the time unit, and the receiving end can detect that the signal amplitude on the time unit is non-zero; if there is no sequence transmitted on a time unit, there is no signal on the time unit, and the receiving end detects that the signal amplitude on the time unit is zero.

[0152] For the receiving end, if a time unit is an ON time unit, or the time unit is in an ON mode, it can be decoded as 1; correspondingly, if the time unit is an OFF time unit, or the time unit is in an OFF mode, it can be decoded as 0.

[0153] For example, if the bit information is 1001, the signal after OOK modulation can be as shown in FIG. 4. Referring to FIG. 4, the bit information 1001 is mapped to four time units (e.g., time unit 1-time unit 4) in sequence after OOK modulation. Among them, the time unit 1 and the time unit 4 have sequences transmitted thereon, which are signal time units or ON time units. The time unit 2 and the time unit 3 have no sequences transmitted thereon, which are non-signal time units or OFF time units. The receiving end can detect the sequence or the signal amplitude not being zero at the time unit 1 and the time unit 4, and thus can be decoded as 1. The sequence or the signal amplitude being zero at the time unit 2 and the time unit 3 is not detected, and thus can be decoded as 0. Thus, the bit information 1001 can be obtained by combining the decoding results of the four time units.

[0154] As can be seen, in the OOK modulation mode, 1 bit of information is transmitted in one time unit. In addition, the sequence detected by the receiving end on the time unit can also be understood as the envelope of the signal on the time unit. Correspondingly, the sequence not detected by the receiving end on the time unit can also be understood as the envelope of the signal on the time unit.

[0155] As can be understood, in the OOK modulation mode, the sequence transmitted on the time unit does not carry bit information, and is only used to make the signal amplitude on the time unit not zero. Alternatively, the sequence transmitted on the time unit can be considered to carry 1 bit of information.

[0156] 5. OFDM modulation:

[0157] The OFDM modulation can carry multiple bits through the sequence transmitted on the time unit. For example, if the sending end can obtain four sequences (e.g., sequence 0-sequence 3), the four sequences can be used to carry 2 bits of information. For example, sequence 0 corresponds to "00", sequence 1 corresponds to "01", sequence 2 corresponds to "10", and sequence 3 corresponds to "11". If the bit information to be sent by the sending end is "01", the sending end can send sequence 1 on the time unit based on the correspondence between the above sequences and the bit information, as shown in FIG. 5.

[0158] For example, in the embodiments of the present application, the sequence transmitted on the time unit in the OFDM modulation mode can also be understood as scrambling the time unit by using the sequence, and the two can be replaced with each other.

[0159] As can be seen from FIG. 5, in a time unit, a sequence transmitted in the time unit can carry multiple bits of information, for example, the sequence 1 transmitted in the time unit in FIG. 3 carries bit information "01". Therefore, compared with OOK modulation, OFDM modulation can transmit or obtain more bits of information in a time unit. Thus, in the case of transmitting bit information of the same length, OFDM modulation occupies less time domain resource than OOK modulation. For example, in the case of transmitting bit information of the same length, OFDM modulation needs to occupy M time units, and OOK modulation needs to occupy N time units. M is less than N, and M and N are integers.

[0160] For example, in an embodiment of the present application, the sequence used to carry information can be one or more of the following sequences: a ZC sequence, a small m sequence, an m sequence, a PDCCH sequence, a gold sequence, a quadrature phase shift keying (QPSK) modulation sequence, a 16 quadrature amplitude modulation (QAM) modulation sequence, a 64 QAM modulation sequence, a binary phase shift keying (BPSK) modulation sequence, a computer search-based sequence, and the like.

[0161] 6. Generation mode of LP-WUS:

[0162] At present, a commonly used generation mode of LP-WUS is OOK modulation based on overlapping OFDM sequences. That is, LP-WUS is based on OOK modulation, and the part of the signal corresponding to one or more sequences in the OOK signal can or can not carry information.

[0163] Specifically, the LP-WUS can be generated in the following three ways:

[0164] Mode 1: OOK modulation is used.

[0165] For example, the part of the signal corresponding to a candidate sequence in each OOK time unit carries information. That is, the sequence does not carry information and is only used to make the signal amplitude not zero. All bits of information of the LP-WUS are carried by the ON / OFF mode of OOK modulation.

[0166] For example, taking the bit information "1001" of the LP-WUS as an example, as shown in (a) of FIG. 6, the bit information "1" is carried by the ON time unit, and the bit information "0" is carried by the OFF time unit. The candidate sequence can be transmitted on the ON time unit, so that the signal amplitude on the ON time unit is not zero.

[0167] In addition, in order to reduce the false detection caused by the interference of noise to the useful signal, a feasible solution is to introduce Manchester coding. For example, as shown in (b) of FIG. 6, when the signal energy in the former time unit is greater than the signal energy in the latter time unit, it represents the bit information "0", and when the signal energy in the former time unit is less than the signal energy in the latter time unit, it represents the bit information "1".

[0168] The second way is to use OOK modulation combined with OFDM modulation.

[0169] For example, the part of each OOK time unit with signal corresponds to multiple candidate sequences. That is, the sequence can carry information. Further, the bit information of the LP-WUS can be carried by the following two ways:

[0170] (1) A part of information is carried by the ON / OFF mode of OOK modulation, and the remaining information is carried by the sequence transmitted on the ON time unit.

[0171] For example, as shown in FIG. 9, the bit information "10" can be carried by the ON time unit and the OFF time unit. In addition, assuming that the ON time unit can correspond to 4 candidate sequences, then the 2-bit information can be carried by the 4 candidate sequences, for example, sequence 0 corresponds to "00", sequence 1 corresponds to "01", sequence 2 corresponds to "10", and sequence 3 corresponds to "11". Taking the sequence 2 transmitted on the ON time unit as an example, the sequence carries the bit information "10". Finally, the bit information of the LP-WUS sent by the sending end is "1010".

[0172] (2) The sequence transmitted on the ON time unit carries all the information.

[0173] For example, still taking the bit information of the LP-WUS as "1010" with 4 bits as an example, all the 4-bit information of the LP-WUS is carried by the sequence transmitted on the ON time unit. For example, in the case of one ON time unit corresponding to 16 candidate sequences, the 4-bit information can be transmitted by one ON time unit; in the case of one ON time unit corresponding to 4 candidate sequences, 2-bit information is transmitted by one ON time unit, and at this time, 2 ON time units are needed to transmit the 4-bit information of the LP-WUS.

[0174] Based on the above description, it can be understood that, compared with the first way, the second way occupies less time domain resource. In addition, the receiving end needs to detect the sequence by correlation detection, and the detection performance is better.

[0175] The third way is to use OOK modulation, and OOK modulation combined with OFDM modulation.

[0176] For example, the third mode can be understood as a combination of the first mode and the second mode. That is, the bit information of the LP-WUS can be modulated / mapped once by the first mode and modulated / mapped once by the second mode.

[0177] For example, taking the bit information of the LP-WUS as "1010" as an example, as shown in FIG. 10, the bit information "1010" can be mapped once by the ON / OFF mode of the OOK modulation, for example, the first and third time units are ON time units, and the second and fourth time units are OFF time units. At the same time, the sequence transmitted by the ON time unit remaps part of the bit information of the LP-WUS, for example, the first and third time units transmit sequence 2. At this time, it is equivalent to carrying all the bit information "1010" of the LP-WUS by the first two time units by the second mode.

[0178] It can be understood that the LP-WUS generated by the third mode occupies the same time domain resource as the LP-WUS generated by the first mode, and is greater than the time domain resource occupied by the LP-WUS generated by the second mode.

[0179] For the receiving end of the LP-WUS, that is, the terminal:

[0180] If the LP-WUR supports envelope detection, or in other words, the LP-WUR is a first type of WUR, the LP-WUR of the terminal performs energy detection on each time unit occupied by the LP-WUS. For example, as shown in (a) of FIG. 6, the time unit corresponding to the bit detected by the energy (for example, the signal amplitude is not zero) can be decoded as "1", and the time unit corresponding to the bit not detected by the energy (for example, the signal amplitude is zero) can be decoded as "0". Or, in the case of introducing Manchester coding, as shown in (b) of FIG. 6, if the energy on adjacent time units is detected to jump from high to low, it can be decoded as "0", and if the energy on adjacent time units is detected to jump from low to high, it can be decoded as "1".

[0181] For example, the structure of the first type of LP-WUR can be as shown in FIG. 7, which includes an envelope detection module. For the input signal, the envelope detection module can perform envelope detection, or in other words, energy detection, so as to decode based on the detection result, and finally output the decoding result.

[0182] Since the first type of WUR cannot perform correlation detection, the first type of WUR can receive the LP-WUS generated by the above-mentioned first mode and third mode, and cannot receive the LP-WUS generated by the above-mentioned second mode.

[0183] If the LP-WUR supports correlation detection, or the LP-WUR is a second type of WUR, the LP-WUR of the terminal has the capability to perform energy detection on each time unit occupied by the LP-WUS and correlation detection. For example, the second type of WUR can first perform energy detection, and then perform correlation detection on the signal in the time unit with higher energy, for example, perform correlation operation on the signal in the time unit with the local sequence, and determine the bit information corresponding to the time unit based on the correlation operation result. Further, correlation detection can also be performed on the signal (for example, the signal can be noise) in the time unit with lower energy.

[0184] For example, the structure of the second type of LP-WUR can be as shown in FIG. 8, which includes an envelope detection module and a digital base band (DBB) module. The envelope detection module is used for envelope detection or energy detection, and the DBB module is used for correlation detection.

[0185] Since the second type of WUR can perform correlation detection, the second type of WUR can receive the LP-WUS generated by any of the above-mentioned manner one, manner two or manner three.

[0186] For example, for the above-mentioned manner one, assuming that the sequence transmitted on the ON time unit is sequence #1, the second type of WUR can perform correlation operation on the signal in each time unit with sequence #1, the time unit with higher correlation value is the ON time unit, and the bit information corresponding thereto can be decoded as “1”, and the time unit with lower correlation value is the OFF time unit, and the bit information corresponding thereto can be decoded as “0”. In addition, in the case of introducing Manchester coding, the second type of WUR can compare the correlation value corresponding to the first time unit with the correlation value corresponding to the second time unit, and in the case that the correlation value corresponding to the first time unit is greater than the correlation value corresponding to the second time unit, the bit information corresponding thereto can be decoded as “0”; and the correlation value corresponding to the third time unit is compared with the correlation value corresponding to the fourth time unit. In the case that the correlation value corresponding to the third time unit is less than the correlation value corresponding to the fourth time unit, the bit information corresponding thereto can be decoded as “1”.

[0187] For example, for the above-mentioned manner two, manner (1), as shown in FIG. 9, the second type of WUR can obtain the bit information “10” through energy detection, and then perform correlation operation on the signal in the ON time unit with the local sequence, and obtain the sequence transmitted on the ON time unit as sequence 2, so as to obtain the bit information “10” according to the correspondence between sequence 2 and the bit information, and thus obtain the complete bit information “1010”.

[0188] For example, for the third mode, as shown in FIG. 10, the second type of WUR can obtain the bit information "10" carried in the first two time units through energy detection, and then perform correlation operation on the signal in the first time unit and the local sequence to obtain the sequence 2 transmitted in the first time unit, so as to obtain the bit information "10" according to the correspondence between the sequence 2 and the bit information, and thus obtain the complete bit information "1010".

[0189] That is, the LP-WUS generated by the above-mentioned first mode and third mode can be received by the terminal with the first type of WUR or the second type of WUR, and the terminal with the second type of WUR can complete the reception in advance when receiving the LP-WUS generated by the third mode compared with the LP-WUS generated by the first mode. For example, in the example shown in FIG. 10, the second type of WUR can obtain the complete bit information by receiving the first two time units, and if the LP-WUS is generated only based on the first mode, the second type of WUR needs to receive four time units to obtain the complete bit information.

[0190] In addition, the LP-WUS generated by the above-mentioned second mode can be received by the terminal with the second type of WUR and cannot be received by the terminal with the first type of WUR. In other words, if the base station generates the LP-WUS according to the above-mentioned second mode, only the terminal with the first type of WUR, or the terminal with only the envelope detection capability of the LP-WUR, cannot successfully receive the LP-WUS.

[0191] 7. Low power synchronous signal (LP-SS):

[0192] In addition to being used for receiving the LP-WUS, the LP-WUR can also be used for receiving the synchronization signal for synchronization and / or measurement process. For example, the synchronization signal can be the synchronization signal (SS) / physical broadcast channel (PBCH) block (SS / PBCH block, SSB) in the new radio (NR) system, or a newly designed synchronization signal, for example, LP-SS.

[0193] For example, the LP-SS can be an OOK-based low-power synchronization signal, or an OFDM-based low-power synchronization signal, or a low-power synchronization signal based on the fusion of different modulation modes, for example, an OOK and OFDM fusion-based low-power synchronization signal, such as scrambling / overlaying OFDM sequence on the ON time unit of OOK.

[0194] For example, for the first type of WUR, receiving OOK modulation based LP-SS for synchronization and / or measurement on the LP-WUR is supported. For the second type of WUR, receiving SSB, OOK modulation based LP-SS, and OOK and OFDM hybrid modulation based LP-SS for synchronization and / or measurement on the LP-WUR is supported.

[0195] For example, as shown in FIG. 11, the LP-SS can be a periodically transmitted synchronization signal. The period of the LP-SS can be greater than the period of the SSB. For example, the period of the SSB is 20 milliseconds (ms), and the period of the LP-SS is 320 ms, 640 ms, 1280 ms, 160 ms, or 80 ms, without limitation. Of course, the period of the LP-SS can also be equal to or less than the period of the SSB, which is not specifically limited in the present application.

[0196] For example, the LP-SS can be a cell-level synchronization signal, or in other words, the LP-SS can be a synchronization signal broadcast in a cell, that is, different terminals in a cell receive the same LP-SS. In addition, the modulation technology of the LP-SS can be consistent with the modulation technology of the LP-WUS, for example, the LP-SS and the LP-WUS use OOK modulation, or the LP-SS and the LP-WUS use OOK combined with OFDM modulation.

[0197] As described above, the LP-WUS can be generated by the above-mentioned method two to save time domain resources. Therefore, in the case of limited network side resources, the network can generate the LP-WUS by method two to ensure that the terminals (referred to as second type of terminals) with relevant detection capabilities of the LP-WUR achieve energy saving, thereby maximizing the balance between terminal energy saving and network load. However, in this scenario, the terminals (referred to as first type of terminals) with only envelope detection capabilities of the LP-WUR can not be able to receive the LP-WUS, thereby failing to achieve energy saving in the current cell.

[0198] That is, the network can enable the LP-WUS function of the second type of terminals and disable the LP-WUS function of the first type of terminals. However, how the network implements the enable / disable control and how the first type of terminals implements energy saving after the network disables the LP-WUS function of the first type of terminals, there is currently no relevant solution.

[0199] Based on this, the application provides a communication method, in which the network side can default the configuration related to the first type of terminal in the configuration information of the wake-up signal, so as to implicitly indicate to disable the LP-WUS function of the first type of terminal. The default configuration may, for example, be the configuration of the LP-SS, the activation / deactivation threshold of the wake-up signal based on the LP-SS measurement, or the configuration of the wake-up signal of the first type of terminal. Through this method, the network can not need to consider multiple types of terminals, reduce the implementation complexity, and can reduce the time domain resource occupancy rate through the OFDM modulation mode to send the LP-WUS. At the same time, compared with the scheme of explicitly indicating the first type of terminal to disable the LP-WUS through the explicit signaling mode, the implicit indication to the first type of terminal to disable only according to the default of the LP-WUS related configuration greatly reduces the signaling load and overhead.

[0200] In addition, in the case that a certain terminal determines that the current serving cell does not support it to monitor the wake-up signal, the cell reselection priority can be updated, and the cell reselection evaluation can be performed according to the updated cell reselection priority. The updating of the cell reselection priority may, for example, include: reducing the cell reselection priority of the serving cell, increasing the cell reselection priority of the frequency point of the neighboring cell supporting it to monitor the wake-up signal, reducing the cell reselection priority of the frequency point of the neighboring cell not supporting it to monitor the wake-up signal, and the like. Through this method, by adjusting the cell reselection priority, the first type of terminal can be reselected to the cell supporting it to monitor the wake-up signal as much as possible during the cell reselection, so as to realize the energy saving of the first type of terminal as much as possible.

[0201] In the embodiments of the application, the communication method will be described in detail in subsequent embodiments, and will not be described here.

[0202] The technical solutions of the embodiments of the application can be applied to various communication systems. The communication system can be a 3GPP communication system, for example, a fourth generation (4th generation, 4G) system such as a long term evolution (long term evolution, LTE) system, a fifth generation (5th generation, 5G) system such as an NR system, a system of mixed networking of LTE and 5G, a communication and sensing integrated system, a non-terrestrial network (non-terrestrial network, NTN), a device-to-device (device-to-device, D2D) communication system, a vehicle-to-everything (vehicle to everything, V2X) communication system, a machine type communication (machine-type communication, MTC) system, an internet of things (internet of things, IoT) system, or other future communication systems. The communication system can also be a non-3GPP communication system, which is not limited.

[0203] The communication system applicable to the present application is only illustrative, and the communication system applicable to the present application is not limited thereto. The communication system provided by the present application does not cause any limitation to the scheme of the present application. Herein, the following will not be described in detail.

[0204] FIG. 12 shows a possible, non-limiting system diagram. As shown in FIG. 12, a communication system 120 includes a radio access network (RAN) 1200 and a core network (CN) 1300. The RAN 1200 includes at least one RAN node (e.g., 1210a and 1210b in FIG. 12, collectively referred to as 1210) and at least one terminal (e.g., 1220a-1220j in FIG. 12, collectively referred to as 1220). The core network 1300 includes at least one core network device. Optionally, the RAN 1200 can further include other RAN nodes, such as a wireless relay device and / or a wireless backhaul device (not shown in FIG. 12), etc. The terminal 1220 is connected to the RAN node 1210 in a wireless manner. The RAN node 1210 is connected to the core network 1300 in a wireless or wired manner. The core network device in the core network 1300 and the RAN node 1210 in the RAN 1200 can be different physical devices respectively, or can be the same physical device integrated with the logical functions of the core network and the logical functions of the radio access network.

[0205] In a possible implementation, the terminal 1220 includes a first receiver and a second receiver. For example, the first receiver is used to monitor / receive / process the wake-up signal, and the second receiver is used for data / service transmission, such as receiving a paging message, a PDCCH, or a physical downlink shared channel (PDSCH), etc. For example, the first receiver can be an LP-WUR, and the second receiver can be an MR. In addition, in the embodiments of the present application, the receiver can also be referred to as a receiving circuit or a receiving link, which can be replaced with each other, and the present application does not make a specific limitation thereto.

[0206] In a possible implementation, the terminal in the embodiments of the present application includes a first type of terminal. Further, it also includes a second type of terminal. For example, the first type of terminal supports envelope detection and does not support correlation detection, for example, the first receiver of the first type of terminal supports envelope detection and does not support correlation detection. The second type of terminal supports correlation detection, for example, the first receiver of the second type of terminal supports correlation detection, and the first receiver of the second type of terminal also supports envelope detection. Wherein, the first type of terminal and the second type of terminal are relative, and the first type of terminal or the second type of terminal can also be understood as follows:

[0207] The first receiver of the first type of terminal is a first type of WUR, and the first receiver of the second type of terminal is a second type of WUR. The first type of WUR and the second type of WUR can refer to the foregoing related description.

[0208] The first type of terminal supports monitoring / receiving a wake-up signal in an envelope detection manner, and the second type of terminal supports monitoring / receiving a wake-up signal in a correlation detection manner.

[0209] The first type of terminal receives a wake-up signal in an envelope / energy / power / amplitude detection manner, and the second type of terminal receives a wake-up signal in a correlation detection manner.

[0210] The first type of terminal can / can detect the energy / power / amplitude of the wake-up signal, and the second type of terminal can / can detect the phase information of the wake-up signal.

[0211] The first receiver of the first type of terminal has envelope detection capability or no correlation detection capability, and the first receiver of the second type of terminal has envelope detection capability.

[0212] The first type of terminal cannot receive a wake-up signal modulated in an OFDM manner (for example, the first type of terminal receives a wake-up signal modulated in an OOK manner), and the second type of terminal can receive a wake-up signal modulated in an OFDM manner.

[0213] The first type of terminal supports an OOK receiver to receive a wake-up signal, and the second type of terminal supports an OFDM receiver to receive a wake-up signal.

[0214] The first type of terminal supports OOK modulation of all bit information of a low-power signal, and the second type of terminal supports mapping of part or all information of a low-power signal to at least one time unit, and the signal amplitude on the at least one time unit is not zero.

[0215] For example, the wake-up signal monitoring performance of the first type of terminal is lower than that of the second type of terminal. The coverage performance supported by the first type of terminal is lower than that supported by the second type of terminal.

[0216] For example, the first type of terminal and the second type of terminal can also have other names, such as OOK terminals or OFDM terminals, and the like. The names of the first type of terminal and the second type of terminal are not specifically limited in the present application.

[0217] As a possible implementation, the terminal 1220 can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely applied to various scenarios, such as D2D, V2X communication, MTC, IoT, virtual reality, augmented reality, industrial control, automatic driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, unmanned aerial vehicle, helicopter, airplane, ship, robot, mechanical arm, smart home device, etc. Embodiments of the present application do not limit the device form of the terminal.

[0218] In a possible implementation, the RAN 1200 can be a 3GPP related cellular system, such as a 4G, 5G mobile communication system, a mobile communication system with mixed networking of 4G and 5G, or a future-oriented evolution system. The RAN 1200 can also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), an NTN network (such as an NTN supporting a transparent mode and / or a regenerative mode, or an NTN supporting a gaze mode (earth fixed cell) and / or a non-gaze mode (earth moving cell)), or a wireless fidelity (WiFi) system. The RAN 1200 can also be a communication system in which two or more of the above systems are fused.

[0219] In some scenarios, the roles of the RAN nodes 1210 and the terminals 1220 are relative, for example, the network element 1220i in FIG. 12 can be a helicopter or an unmanned aerial vehicle, which can be configured as a mobile base station. For a terminal 1220j accessing the RAN 1200 through the network element 1220i, the network element 1220i is a base station; but for the base station 1210a, the network element 1220i is a terminal. The RAN nodes 1210 and the terminals 1220 are sometimes collectively referred to as communication apparatuses, for example, the network elements 1210a and 1210b in FIG. 12 can be understood as communication apparatuses with base station functions, and the network elements 1220a-1220j can be understood as communication apparatuses with terminal functions.

[0220] In some scenarios, the communication between the RAN node 1210 and the terminal 1220 follows a certain protocol layer structure, which can include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer can include at least one of a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a media access control (MAC) layer, or a physical (PHY) layer, etc. The user plane protocol layer can include at least one of a service data adaptation protocol (SDAP) layer, a PDCP layer, an RLC layer, a MAC layer, or a physical layer, etc.

[0221] As a possible implementation, the RAN node 1210, which can also be referred to as a RAN entity or an access node, etc., forms part of a communication system to help terminals to access the wireless communication. The RAN nodes 1210 in the communication system 120 can be of the same type or of different types.

[0222] In a possible scenario, the RAN node 1210 can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a base station in a future mobile communication system, or an access node in a WiFi system, etc. The RAN node can be a macro base station (e.g., 1210a in FIG. 12), a micro base station or an indoor station (e.g., 1210b in FIG. 12), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the RAN node in the V2X technology can be a road side unit (RSU).

[0223] In another possible scenario, a terminal device accesses a wireless network by means of cooperation among a plurality of RAN nodes, and different RAN nodes respectively implement part of functions of an access network device (e.g., a base station). For example, a RAN node can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately configured, or can be included in the same network element, for example, in a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, for example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0224] In different systems, the CU (or CU-CP and CU-UP), the DU, or the RU can also have different names, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-RAN central unit (O-CU), the DU can also be referred to as an O-RAN distributed unit (O-DU), the CU-CP can also be referred to as an O-RAN central unit control plane (O-CU-CP), the CU-UP can also be referred to as an O-RAN central unit user plane (O-CU-UP), and the RU can also be referred to as an O-RAN radio unit (O-RU). Any of the CU (or CU-CP, CU-UP), the DU, and the RU in this application can be implemented by means of a software module, a hardware module, or a combination of a software module and a hardware module.

[0225] As a possible implementation, the CU, the DU, and the RU respectively implement part of protocol layer functions of an access network device, for example, part of protocol layer functions are implemented in the CU, and the remaining part or all protocol layer functions are implemented in the DU, and the CU can control one or more DUs. One DU can be connected to one or more RUs.

[0226] As shown in (a) of FIG. 13, for example, the CU can deploy the RRC layer, the SDAP layer, and the PDCP layer, or in other words, the CU can be understood as a logical node that carries the RRC layer, the SDAP layer, and the PDCP layer of the access network device. Thus, the CU has the processing capability of the RRC, PDCP, and SDAP layers, and of course, the CU can also implement or carry other control functions. The DU can deploy the RLC layer, the MAC layer, and the PHY layer, or in other words, the DU can be understood as a logical node that carries the RLC layer, the MAC layer, and the PHY layer, and thus, the DU has the processing capability of the RLC, MAC, and PHY layers, and of course, the DU can also implement or carry other functions. The RU can deploy the RRC layer (not shown in FIG. 13).

[0227] Optionally, the CU (for example, the PDCP layer and higher layers) is connected to the DU (for example, the RLC layer and lower layers) through some interfaces, which can be F1 and the like. In some examples, these interfaces (for example, the F1 interface) can provide control plane (C-Plane) and user plane (U-Plane) functions (for example, interface management, system information management, UE context management, RRC message transmission, and the like). For example, the F1 supports the control plane function through F1-C and supports the user plane function through F1-U.

[0228] In an example, the CU can include a CU-CP and a CU-UP. As shown in (b) of FIG. 13, the CU-CP can be understood as a logical node that carries the RRC layer and the control plane part of the PDCP (PDCP-C), and is used to implement the control plane function of the CU. The CU-UP can be understood as a logical node that carries the SDAP layer and the user plane part of the PDCP (PDCP-U), and is used to implement the user plane function of the CU. The CU-CP and the CU-UP can communicate through the E1 interface.

[0229] The above division of functions of the CU and the DU is only an example and does not constitute a limitation on the CU and the DU. In addition, the CU and the DU can also be configured to have the functions as needed. For example, the CU or the DU can be configured as a node having more protocol layer functions, or the CU or the DU can be configured as a node having partial processing functions of the protocol layers. For example, part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to the service type or other system requirements, for example, according to the delay, the functions that need to meet a relatively short delay requirement are arranged in the DU, and the functions that do not need to meet the delay requirement are arranged in the CU.

[0230] In one possible implementation, as shown in FIG. 14, a possible, non-limiting O-RAN system schematic diagram is provided. Referring to FIG. 14, the O-RAN system can include an orchestration layer with a non-real time RAN intelligent controller (Non-RT RIC or NRT RIC), and a function layer with a near-real time RAN intelligent controller (Near-RT RIC or nRT RIC). The orchestration layer and the function layer can communicate through interface Al.

[0231] For example, the Non-RT RIC is used to implement non-real time intelligent management of the RAN, and can implement artificial intelligence (AI) / machine learning (ML) including model training and model updating, and guide applications / functions in the Near-RT RIC based on a policy. The Near-RT RIC is used to implement near-real time intelligent management of the RAN, and implements near-real time control and optimization of modules and resources of the O-RAN through data collection and related operations on the E2 interface. The E2 interface can be understood as an open interface between two nodes (or endpoints), for example, an interface between the function layer and the O-CU, O-DU. In addition, the O-CU can include an O-CU-CP and an O-CU-UP, and the O-DU can communicate through a fronthaul interface. Related implementations of the O-CU, O-DU, and O-RU can be referred to the foregoing related descriptions, and will not be described here.

[0232] For example, in addition to non-real time intelligent management of the RAN, the orchestration layer can also implement design, inventory, configuration, and the like. The function layer can also implement 3rd party application management, radio connection management, mobility management, QoS management, interference management, trained model, and the like.

[0233] All or part of the functions of the RAN node in this application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform, such as a cloud platform. The RAN node in this application can also be a logical node, a logical module or software that can implement all or part of the functions of the RAN node.

[0234] In a possible implementation, the core network device can refer to a device in the core network 1300 that provides service support for the terminal. Illustratively, the core network device can include at least one of the following: an access and mobility management function (AMF) network element, a session management function (SMF) network element, a user plane function (UPF) network element, and the like. Of course, the core network 1300 can also include other core network devices, which are not limited.

[0235] Illustratively, the AMF network element is mainly responsible for mobility management in the mobile network, such as user location update, user registration network, user handover, and the like. The SMF network element is mainly responsible for session management in the mobile network, such as session establishment, modification, release, and the like. The UPF network element is a functional network element of the user plane, which is mainly responsible for connecting external networks and processing user messages, such as forwarding, charging, and the like.

[0236] Illustratively, the network element in the core network can send information to the terminal, such as paging information, terminal packet related information, and the like. The terminal can also send information to the network element in the core network, such as terminal capability information, terminal characteristic information, and the like.

[0237] It should be noted that the system described in the embodiments of the present application is to more clearly illustrate the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of network architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0238] The communication method provided by the embodiments of the present application will be described below by taking the interaction between the terminal and the RAN node in the communication system shown in FIG. 13 as an example. It should be noted that in the following embodiments of the present application, the names of messages between the terminal and the RAN node, the names of parameters, or the names of information, etc. are only examples, and in other embodiments, they can also be other names, and the method provided by the present application does not make specific limitations.

[0239] It can be understood that, in the embodiments of the present application, the terminal or the RAN node can perform part or all of the steps in the embodiments of the present application, and these steps or operations are only examples, and the embodiments of the present application can also perform other operations or variations of various operations. In addition, various steps can be performed in different orders as presented in the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application are performed.

[0240] It can be understood that, in the embodiments of the present application, the terminal and the RAN node are taken as an example for illustrating the execution subject of the interaction, but the present application does not limit the execution subject of the interaction. For example, the method performed by the terminal in the present application can also be performed by a module (such as a chip, a chip system, or a processor) applied to the terminal, and can also be implemented by a logical node, a logical module or software capable of implementing all or part of the terminal functions; the method performed by the RAN node in the present application can also be performed by a module (such as a chip, a chip system, or a processor) applied to the RAN node, and can also be implemented by a logical node, a logical module or software capable of implementing all or part of the RAN node functions.

[0241] The communication method provided by the embodiments of the present application will be described below. As shown in FIG. 15, the communication method can include the following steps:

[0242] S1501, the RAN node sends first configuration information. Correspondingly, the first terminal receives the first configuration information.

[0243] Among them, the first terminal is any first type terminal. That is, any first type terminal can implement the functions implemented by the first terminal in the embodiments of the present application, and the first terminal is only taken as an example for illustration in the present application. The implementation of the first type terminal can refer to the related description described above, which will not be repeated here.

[0244] Among them, the first configuration information is used to indicate the configuration of the wake-up signal. The first configuration information is default to the first configuration, which is related to the first type terminal. Illustratively, the first configuration information is default to the first configuration, which can also be understood as: the first configuration information does not include the first configuration. The first configuration information can be understood as the related configuration of the wake-up signal.

[0245] In a possible implementation, in the case that the first configuration information is default to the first configuration, it represents / indicates that the current serving cell does not support the first type terminal to monitor the wake-up signal, or represents / indicates that the frequency point where the current serving cell is located does not support the first type terminal to monitor the wake-up signal. Illustratively, the wake-up signal is used to indicate whether there is a paging message in the candidate, or whether there is a PDCCH transmission or data service transmission in the future, for example, the wake-up signal can be LP-WUS.

[0246] For example, for the convenience of description, the frequency point on which the serving cell is located is referred to as a serving frequency point in the following embodiments. In the case where the current serving cell does not support the first type of terminal to monitor the wake-up signal, other cells on the serving frequency point can support the first type of terminal to monitor the wake-up signal, or can not support the first type of terminal to monitor the wake-up signal. In the case where the serving frequency point does not support the first type of terminal to monitor the wake-up signal, it can be considered that all the cells on the serving frequency point do not support the first type of terminal to monitor the wake-up signal.

[0247] As a possible implementation, not supporting the first type of terminal to monitor the wake-up signal includes at least one of the following: not allowing the first type of terminal to monitor the wake-up signal, not supporting the first type of terminal to be provided with the wake-up signal, the provided wake-up signal not supporting / allowing the first type of terminal to monitor, the provided wake-up signal being unable to be demodulated by the first type of terminal, not supporting / allowing the first type of terminal to use the wake-up signal, the first type of terminal being disabled from the wake-up signal, the first type of terminal being disabled from monitoring the wake-up signal, the function of the first type of terminal monitoring the wake-up signal being disabled, or the first receiver of the first type of terminal being disabled.

[0248] In a possible implementation, the first configuration information can be carried by broadcast signaling, for example, the first configuration information can be carried in a system message such as SIB. Alternatively, the first configuration information is carried by dedicated non-access stratum (NAS) signaling or dedicated RRC signaling, for example, the RRC signaling can be an RRC reconfiguration message, an RRC release message, etc.

[0249] In a possible implementation, the first terminal receives the first configuration information by using the second receiver, or the second receiver of the first terminal receives the first configuration information.

[0250] S1502, the first terminal determines, according to the first configuration information, that the serving cell / serving frequency point does not support the first type of terminal to monitor the wake-up signal.

[0251] In a possible implementation, the first terminal determines that the serving cell / serving frequency point does not support the first type of terminal to monitor the wake-up signal, which can also be understood as: the first terminal determines that the serving cell / serving frequency point does not support the first terminal to monitor the wake-up signal; or the first terminal is unable to monitor the wake-up signal in the serving cell / serving frequency point; or the wake-up signal of the serving cell / serving frequency point does not support the first terminal to monitor.

[0252] In a possible implementation, after receiving the first configuration information, the first terminal can know that the first configuration information related to the first type of terminal is defaulted in the first configuration information, so as to determine that the serving cell / serving frequency point does not support the first type of terminal to monitor the wake-up signal. The description of not supporting the first type of terminal to monitor the wake-up signal can refer to the related description in the above step S1401, which is not repeated here.

[0253] In a possible implementation, after the first terminal determines that the serving cell / serving frequency point does not support the first type of terminal to monitor the wake-up signal, the second receiver (e.g., the MR) can be controlled to remain in an open state to monitor the paging message according to the paging procedure or to monitor the PDCCH according to the PDCCH blind detection procedure; or the cell reselection evaluation can be performed to reselect to a cell that supports the first type of terminal to monitor the wake-up signal, so as to achieve the energy saving of the first type of terminal. The implementation of the cell reselection evaluation can refer to the scheme shown in FIG. 16 or can be performed according to the existing cell reselection evaluation procedure, which is not limited in the present application.

[0254] Based on the scheme, the network side can disable the function of the first type of terminal to monitor the wake-up signal in the current cell, thus avoiding the invalid monitoring of the wake-up signal by the first type of terminal. In addition, the network side can not need to consider the problem of multiple types of terminals monitoring the wake-up signal, reducing the implementation complexity. Moreover, the wake-up signal can be transmitted in the manner of OFDM modulation, which can reduce the time domain resource occupancy rate and save the time domain resources compared with the case of transmitting the wake-up signal in the manner of OOK modulation. In addition, compared with the scheme of indicating that the serving cell / serving frequency point does not support the first type of terminal to monitor the wake-up signal through explicit signaling, the scheme of indicating that the serving cell / serving frequency point does not support the first type of terminal to monitor the wake-up signal by defaulting the first configuration related to the first type of terminal in the related configuration of the wake-up signal can reduce the signaling load and overhead.

[0255] In a possible implementation, the first configuration in the embodiments of the present application can have the following three implementation manners:

[0256] Manner 1: The first configuration is the configuration of the LP-SS.

[0257] That is, in the case of defaulting the configuration of the LP-SS in the related configuration of the wake-up signal, it is indicated that the current serving cell / serving frequency point does not support the first type of terminal to monitor the wake-up signal.

[0258] For example, the period of the LP-SS can be one of 80 ms, 160 ms, 320 ms, 640 ms, and 1280 ms. The generation / modulation manner of the LP-SS can be the manner described in the above manner one, manner two, or manner three. The time domain resource position of the LP-SS can include the time domain starting position, the number of occupied time domain symbols, etc.; the frequency domain resource position of the LP-SS can include the frequency domain starting position, the number of occupied subcarriers or resource elements (REs), etc.

[0259] Based on the manner 1, since the first receiver of the terminal can perform synchronization and / or measurement by receiving the SSB or the LP-SS, for the first type of terminal, it cannot receive the SSB, i.e., the first type of terminal can only receive the LP-SS based on the OOK modulation to perform synchronization and / or measurement, therefore, in the case that the configuration of the LP-SS is defaulted in the related configuration of the wake-up signal, the first type of terminal cannot receive the LP-SS. Since the first type of terminal also cannot receive the SSB, it can be considered that the first type of terminal cannot perform synchronization and / or measurement through the first receiver. In the case that the first type of terminal cannot perform synchronization and / or measurement, the first type of terminal also cannot monitor the wake-up signal, and thus it can be considered that the current serving cell / serving frequency point does not support the first type of terminal to monitor the wake-up signal. That is, the current serving cell / serving frequency point not supporting the first type of terminal to monitor the wake-up signal can be implicitly indicated by defaulting the configuration of the LP-SS.

[0260] As a possible implementation, in the case that the configuration of the LP-SS is defaulted at the network side, the second type of terminal can perform synchronization and / or measurement by receiving the SSB, so as to normally receive / monitor the wake-up signal in the current serving cell.

[0261] The manner 2, the first configuration is a first threshold. The first threshold includes an activation threshold and / or a deactivation threshold of the wake-up signal based on the LP-SS measurement. That is, the first threshold can be used as a threshold for activating / deactivating the wake-up signal based on the LP-SS measurement.

[0262] As a possible implementation, activating / deactivating the wake-up signal can also be understood as activating / deactivating the function of the wake-up signal, activating / deactivating the monitoring of the wake-up signal, activating / deactivating the function of the monitoring of the wake-up signal, enabling / disabling the wake-up signal, enabling / disabling the function of the wake-up signal, enabling / disabling the monitoring of the wake-up signal, enabling / disabling the function of the monitoring of the wake-up signal, etc.

[0263] As a possible implementation, generally, the network side can respectively configure corresponding thresholds for the LP-SS based measurement and the SSB based measurement as the thresholds for activating / deactivating the wake-up signal.

[0264] For example, the network side can configure threshold 1 as the threshold of the activation / deactivation of the wake-up signal for the measurement based on the LP-SS and threshold 2 as the threshold of the activation / deactivation of the wake-up signal for the measurement based on the SSB. If the measurement result based on the LP-SS on the first receiver of the first type of terminal is less than threshold 1, the first type of terminal deactivates the wake-up signal, or the wake-up signal is deactivated for the first type of terminal, or the function of monitoring the wake-up signal by the first type of terminal is deactivated, for example, the first type of terminal exits the monitoring of the wake-up signal and wakes up the second receiver. If the measurement result based on the LP-SS on the first receiver of the first type of terminal is greater than or equal to threshold 1, the first type of terminal monitors the wake-up signal through the first receiver, and wakes up the second receiver if the wake-up signal is monitored.

[0265] If the measurement result based on the SSB on the first receiver of the second type of terminal is less than threshold 2, the second type of terminal deactivates the wake-up signal, or the wake-up signal is deactivated for the second type of terminal, or the function of monitoring the wake-up signal by the second type of terminal is deactivated, for example, the second type of terminal exits the monitoring of the wake-up signal and wakes up the second receiver. If the measurement result based on the LP-SS on the first receiver of the second type of terminal is greater than or equal to threshold 2, the second type of terminal monitors the wake-up signal through the first receiver, and wakes up the second receiver if the wake-up signal is monitored.

[0266] For example, the measurement based on the LP-SS can be understood as the measurement of the LP-SS, and the measurement result based on the LP-SS can be understood as the measurement result of the LP-SS. The measurement based on the SSB can be understood as the measurement of the SSB, and the measurement result based on the SSB can be understood as the measurement result of the SSB. The measurement result can be, for example, the reference signal receiving power (RSRP), the reference signal receiving quality (RSRQ), the signal to interference plus noise ratio (SINR), and the like.

[0267] Based on the above possible implementation, in the mode 2, the first configuration information can include the activation / deactivation threshold of the wake-up signal based on the SSB measurement, for example, threshold 2 described above, and the first configuration information can default the activation / deactivation threshold of the wake-up signal based on the LP-SS measurement, for example, threshold 1 described above.

[0268] Since the first receiver of the terminal can perform measurement and / or synchronization by receiving SSB or LP-SS, for the first type of terminal which cannot receive SSB, i.e., the first type of terminal can only receive LP-SS based on OOK modulation to perform synchronization and / or measurement, in the case that the related configuration of the wake-up signal lacks the default activation / deactivation threshold of the wake-up signal based on LP-SS measurement, the first type of terminal cannot determine the timing of activating / deactivating the wake-up signal based on the LP-SS measurement, and thus cannot determine whether to monitor or not to monitor the wake-up signal. Since the first type of terminal also cannot receive SSB, it can be considered that the first type of terminal cannot monitor the wake-up signal, and thus it can be considered that the current serving cell / serving frequency point does not support the first type of terminal to monitor the wake-up signal. That is, the current serving cell / serving frequency point can implicitly indicate that it does not support the first type of terminal to monitor the wake-up signal by defaulting the activation / deactivation threshold based on LP-SS measurement.

[0269] As a possible implementation, the first configuration information can default the activation / deactivation threshold of the wake-up signal based on SSB measurement, and default the activation / deactivation threshold of the wake-up signal based on LP-SS measurement. At this time, a default value can be used as the activation / deactivation threshold of the wake-up signal. For example, a first default value can be used as the activation / deactivation threshold of the wake-up signal based on SSB measurement, and a second default value can be used as the activation / deactivation threshold of the wake-up signal based on LP-SS measurement.

[0270] For example, the first default value and the second default value can both exist, and the first default value and the second default value can be the same or different; or the first default value can exist, and the second default value can not exist, at this time, it can also implicitly indicate that the current serving cell / serving frequency point does not support the first type of terminal to monitor the wake-up signal.

[0271] For example, the first default value and / or the second default value can be pre-defined by the protocol, or can be configured by the RAN node to the terminal through system message or dedicated signaling. A typical default value can be -inf (negative infinity).

[0272] Option 3: The first configuration information includes the configuration of the wake-up signal of the second type of terminal, and the first configuration is the configuration of the wake-up signal of the first type of terminal. The implementation of the second type of terminal can refer to the foregoing related description, which will not be repeated here.

[0273] As a possible implementation, the network can configure the wake-up signal for the first type of terminal and the second type of terminal respectively. That is, a set of wake-up signal configurations is sent to the first type of terminal for the first type of terminal to monitor the wake-up signal, and another set of wake-up signal configurations is sent to the second type of terminal for the second type of terminal to monitor the wake-up signal.

[0274] In this implementation, the above-described manner 3 can be understood as: the network side sends the configuration of the wake-up signal of the second type of terminal, and does not send or defaults the configuration of the wake-up signal of the first type of terminal. Or, the network side configures the wake-up signal for the second type of terminal, or configures the wake-up signal for the second type of terminal, and does not configure the wake-up signal for the first type of terminal, or does not configure the wake-up signal for the first type of terminal.

[0275] Based on the above-described manner 3, since the network side configures the wake-up signal for the first type of terminal and the second type of terminal respectively, in the case that the network side defaults the configuration of the wake-up signal of the first type of terminal, the first type of terminal cannot obtain the related information of the wake-up signal, so as to not monitor the wake-up signal, and thus it can be considered that the current serving cell / serving frequency point does not support the first type of terminal to monitor the wake-up signal. That is, the default of the configuration of the wake-up signal of the first type of terminal can implicitly indicate that the current serving cell / serving frequency point does not support the first type of terminal to monitor the wake-up signal.

[0276] The above provides a method for disabling the first type of terminal to monitor the wake-up signal. In addition, the present application also provides a communication method for performing cell reselection in the case that the serving cell does not support the terminal to monitor the wake-up signal, so as to reselect to a cell supporting the terminal to monitor the wake-up signal as much as possible, thereby realizing the energy saving of the terminal. As shown in FIG. 16, the communication method comprises the following steps:

[0277] S1601, the first terminal determines that the serving cell does not support the first terminal to monitor the wake-up signal. That is, a certain terminal determines that the serving cell does not support itself to monitor the wake-up signal.

[0278] As a possible implementation, the first terminal can be the first type of terminal, or the first terminal can be the second type of terminal. The implementation of the first type of terminal and the second type of terminal can be referred to the above-described related description, which will not be described here.

[0279] As another possible implementation, the first terminal can be other types of terminals, or terminals satisfying other conditions, or any terminal in the serving cell. That is, the first terminal can be any terminal that is disabled to monitor the wake-up signal.

[0280] As a possible implementation, the RAN node can explicitly indicate that the serving cell does not support the first terminal to monitor the wake-up signal. For example, the RAN node can send indication information, which explicitly indicates that the serving cell does not support the first terminal to monitor the wake-up signal. For example, the indication information can include the terminal type of the first terminal, the identity of the first terminal, the identity of the terminal group to which the first terminal belongs, etc. In addition, the indication information can be carried in the system message, the NAS signaling, or the RRC dedicated signaling.

[0281] As another possible implementation, the RAN node can implicitly indicate that the serving cell does not support the first terminal monitoring the wake-up signal. For example, the RAN node defaults the configuration related to the first terminal in the related configuration of the wake-up signal to implicitly indicate that the serving cell does not support the first terminal monitoring the wake-up signal. The related implementation can refer to the above-mentioned method shown in FIG. 15, and will not be described here again.

[0282] As a possible implementation, the implementation of not supporting the first terminal monitoring the wake-up signal can refer to the above-mentioned step S1501 related description of not supporting the first type of terminal monitoring the wake-up signal, and will not be described here again.

[0283] S1602, the first terminal performs cell reselection evaluation.

[0284] That is, in the case where the first terminal determines that the serving cell does not support the first terminal monitoring the wake-up signal, the cell reselection evaluation is performed. Exemplarily, the cell reselection evaluation includes at least one of the following:

[0285] performing cell reselection evaluation according to at least one of the updated cell reselection priority of the serving cell, the cell reselection priority of the frequency point where the serving cell is located, or the cell reselection priority of the frequency point where the neighbor cell is located; or,

[0286] performing neighbor cell measurement in the case where the signal quality of the serving cell is greater than the first threshold; or,

[0287] performing cell reselection evaluation according to the first frequency point list, the cells on the frequency points in the first frequency point list support the first terminal monitoring the wake-up signal; or,

[0288] performing cell reselection evaluation according to the cell list, the cells in the cell list support the first terminal monitoring the wake-up signal.

[0289] The following will describe the above-mentioned four implementation modes of the cell reselection evaluation respectively.

[0290] Mode A, performing cell reselection evaluation according to at least one of the updated cell reselection priority of the serving cell, the cell reselection priority of the frequency point where the serving cell is located, or the cell reselection priority of the frequency point where the neighbor cell is located.

[0291] That is, in the case where the first terminal determines that the serving cell does not support the first terminal monitoring the wake-up signal, the cell reselection priority can be updated / adjusted, and the cell reselection evaluation is performed according to the updated / adjusted cell reselection priority. Exemplarily, there can be three ways to update the cell reselection priority:

[0292] The method A1 updates the cell reselection priority of the serving cell to the first priority, or updates the cell reselection priority of the first frequency point to the first priority. The first frequency point is the frequency point on which the serving cell is located, and can also be referred to as the serving frequency point.

[0293] The first priority is the lowest priority, or the first priority is lower than the cell reselection priority of the frequency point on which the first cell is located. The first cell is a neighbor cell that supports the first terminal to monitor the wake-up signal.

[0294] The lowest priority can be the lowest cell reselection priority defined by a protocol, or can be the lowest cell reselection priority in the cell reselection priorities of the frequency points on which all cells in the intra-frequency neighbor cell list, the inter-frequency neighbor cell list, and the inter-system neighbor cell list are located.

[0295] The first cell is a cell in the first cell list. The first cell list includes at least one of the intra-frequency neighbor cell list, the inter-frequency neighbor cell list, or the inter-system neighbor cell list of the serving cell. When the first terminal updates the cell reselection priority of the serving cell to the first priority, the first cell can be an intra-frequency neighbor cell, an inter-frequency neighbor cell, or a system neighbor cell. When the first terminal updates the cell reselection priority of the first frequency point to the first priority, the first cell can be an inter-frequency neighbor cell or a system neighbor cell. The first cell list can be broadcast by the RAN node through a system message.

[0296] In a possible implementation, before step S1601, the RAN node can also indicate the cell reselection priority of the first frequency point. For example, as shown in FIG. 16, the RAN node can send first information, and the first terminal receives the first information. The first information indicates the cell reselection priority of the first frequency point. For example, the first information indicates that the cell reselection priority of the first frequency point is priority A. It can be understood that, since the serving cell is a cell on the first frequency point, the first information can also indicate that the cell reselection priority of the serving cell is priority A. Further, before step S1601, the RAN node can also indicate the cell reselection priority of the neighbor cell.

[0297] As a possible implementation, when the cell reselection priority of the serving cell is updated to the first priority, the cell reselection priority of the other cell on the first frequency point except the serving cell is still priority A. When the cell reselection priority of the first frequency point is updated to the first priority, it can be considered that the cell reselection priority of all cells (including the serving cell) on the first frequency point is the first priority.

[0298] Optionally, the cell reselection priority can be the cell reselection priority after priority enhancement for the wake-up signal (hereinafter referred to as the wake-up signal cell reselection priority), or can be the original cell reselection priority without priority enhancement.

[0299] For example, the priority enhancement for the wake-up signal can be understood as defining a new cell reselection priority for the cell supporting the wake-up signal, which is higher than the original cell reselection priority. The purpose is to increase the cell reselection priority so that the terminal can reselect to the cell supporting the wake-up signal as much as possible to achieve energy saving.

[0300] For example, the cell supporting the wake-up signal can also be understood as the cell supporting sending the wake-up signal, the cell providing the wake-up signal, the cell supporting energy saving based on the wake-up signal, the cell being an energy saving cell, etc., which can be replaced with each other.

[0301] For example, in the case of priority enhancement, taking the serving cell as cell #0, and the neighboring cells including cell #1 and cell #2 as examples, the related original configurations of cell #0, cell #1 and cell #2 can be as shown in Table 1.

[0302] Table 1

[0303] Referring to Table 1, before step S1601, cell #0 and cell #1 support the wake-up signal and support the first type of terminal monitoring the wake-up signal, and also support the second type of terminal monitoring the wake-up signal. The original cell reselection priority of the frequency point where cell #0 is located is 4, and the enhanced wake-up signal cell reselection priority is 8; the original cell reselection priority of the frequency point where cell #1 is located is 3, and the enhanced wake-up signal cell reselection priority is 8. Cell #2 does not support the wake-up signal, and thus does not support any terminal monitoring the wake-up signal, and the original cell reselection priority of the frequency point where it is located is 5. Since it does not support the wake-up signal, its wake-up signal cell priority and the original cell reselection priority are the same.

[0304] In addition, the type of terminal supporting monitoring the wake-up signal can also be understood / alternatively as the type of the first receiver supported. The type of the first receiver can include the first type of WUR or the second type of WUR. Among them, the first receiver of the first type of terminal is the first type of WUR, and the first receiver of the second type of terminal is the second type of WUR. Therefore, the first type of terminal in the above Table 1 can be replaced by the first type of WUR, and the second type of terminal can be replaced by the second type of WUR.

[0305] It should be noted that the priority of cell reselection in the table of the embodiments of the present application is taken as an example for explanation. In the case where the cell reselection priority can be the cell reselection priority of the cell, the cell reselection priority of the frequency point in the table can also be replaced by the cell reselection priority of the cell, which is uniformly described here and will not be described again in subsequent embodiments.

[0306] In the case where no priority enhancement is performed, taking the serving cell as cell #0, and the neighboring cells including cell #1 and cell #2 as an example, the relevant original configurations of cell #0, cell #1 and cell #2 can be as shown in Table 2.

[0307] Table 2

[0308] Wherein, the description of Table 2 can refer to the relevant description in Table 1, which will not be repeated here.

[0309] Taking the first terminal as a first type of terminal, i.e., the serving cell does not support the first type of terminal to monitor the wake-up signal as an example, based on the above examples of Table 1 or Table 2, the serving cell is cell #0, the first cell is the neighboring cell supporting the first terminal to monitor the wake-up signal, i.e., cell #1, then the first terminal can update the cell reselection priority of the serving cell to the first priority, or update the cell reselection priority of the first frequency point to the first priority. Taking the first priority as the lowest priority (priority value is 1) as an example, after updating the priority, the relevant configurations of cell #0, cell #1 and cell #2 corresponding to Table 1 can be updated to Table 3; the relevant configurations of cell #0, cell #1 and cell #2 corresponding to Table 2 can be updated to Table 4.

[0310] Table 3

[0311] Table 4

[0312] Referring to Table 3 or Table 4, in step S1601, the first terminal determines that the serving cell does not support the first type of terminal to monitor the wake-up signal, so the terminal type of cell #0 supporting monitoring the wake-up signal is updated from the first type of terminal + the second type of terminal to the second type of terminal. Then, the wake-up signal cell reselection priority of cell #0 or the original cell reselection priority of the frequency point where cell #0 is located (corresponding to Table 3) or (corresponding to Table 4) is updated to the first priority (priority value is 1). After updating the priority, the cell reselection priority of the serving cell or the first frequency point is lower than the cell reselection priority of the frequency point where cell #1 supporting the first type of terminal to monitor the wake-up signal is located (priority value is 8 or 3). At this time, in the case where the first terminal performs cell reselection evaluation, it will trigger high-priority neighboring cell reselection, and in the case where cell #1 meets the cell reselection evaluation criteria of the high-priority neighboring cell, the first terminal can reselect to cell #1.

[0313] Based on the above manner A1, in the case that the serving cell does not support the terminal to monitor the wake-up signal, the terminal can update the cell reselection priority of the serving cell or the serving frequency to the lowest priority, or to a priority lower than the priority of the frequency on which the cell supporting the terminal to monitor the wake-up signal is located. Therefore, in subsequent cell reselection, due to the low priority of the serving cell or the serving frequency and the high priority of the cell reselection priority of the frequency on which the cell supporting the terminal to monitor the wake-up signal is located, the terminal can trigger high-priority neighbor cell reselection, so as to reselect the cell supporting the terminal to monitor the wake-up signal as much as possible, thereby realizing the energy saving of the terminal.

[0314] Manner A2, updating the cell reselection priority of the second frequency to the second priority. The second frequency is the frequency on which the first cell is located, and the first cell is the neighbor cell supporting the first terminal to monitor the wake-up signal. For details, please refer to the above description of the first cell in manner A1, which will not be repeated here.

[0315] As a possible implementation, in the case that the second frequency is different from the frequency on which the serving cell is located, i.e., in the case that the first cell is an inter-frequency or inter-system neighbor cell, the second priority is the highest priority; or the second priority is higher than the cell reselection priority of the frequency on which the serving cell is located. For example, the cell reselection priority of the frequency on which the serving cell is located can be the priority A before updating, or can be the first priority after updating.

[0316] As another possible implementation, in the case that the second frequency is the same as the frequency on which the serving cell is located, i.e., in the case that the first cell is an intra-frequency neighbor cell: the second priority is the highest priority; or the second priority is higher than the cell reselection priority of the serving cell. For example, the cell reselection priority of the serving cell can be the priority A before updating, or can be the first priority after updating.

[0317] That is, in this possible implementation, the cell reselection priority of the serving cell is different from the cell reselection priority of the frequency on which the serving cell is located (or the cell reselection priority of the other cell on the frequency except the serving cell). For example, the cell reselection priority of the serving cell is the priority A or the first priority, and the cell reselection priority of the frequency on which the serving cell is located (or the cell reselection priority of the other cell on the frequency except the serving cell) is the second priority.

[0318] For example, the highest priority can be the highest cell reselection priority defined by the protocol, or can be the highest cell reselection priority among the cell reselection priorities of the frequencies on which all the cells in the intra-frequency neighbor cell list, the inter-frequency neighbor cell list, and the inter-system neighbor cell list are located.

[0319] In a possible implementation, before step S1601, the RAN node can also indicate the cell reselection priority of the second frequency point. For example, the RAN node can send second information, and the first terminal receives the second information, where the second information indicates the cell reselection priority of the second frequency point. For example, the second information indicates that the cell reselection priority of the second frequency point is priority B.

[0320] As a possible implementation, when the second frequency point is different from the frequency point where the serving cell is located, i.e., the first cell is a different-frequency or different-system neighbor cell, the second information and the first information are different information, and the priority B is different from the priority A. When the second frequency point is the same as the frequency point where the serving cell is located, i.e., the first cell is a same-frequency neighbor cell, the second information and the first information are the same information, and the priority B is the same as the priority A.

[0321] Optionally, the cell reselection priority can be the cell reselection priority after the priority enhancement of the wake-up signal, or can be the original cell reselection priority without the priority enhancement. For details, refer to the description in the above manner A1, which will not be repeated here.

[0322] For example, the serving cell is cell #0, the neighbor cells include cell #1 and cell #2, and the related original configurations of the cell #0, the cell #1 and the cell #2 are shown in the above table 1 or table 2. Taking the cell #1 as a different-frequency or different-system neighbor cell as an example, when the first terminal is a first-type terminal, i.e., the serving cell does not support the first-type terminal to monitor the wake-up signal, based on the above examples of the table 1 or the table 2, the serving cell is the cell #0, the first cell is the neighbor cell that supports the first terminal to monitor the wake-up signal, i.e., the cell #1, and the first terminal can update the cell reselection priority of the frequency point where the cell #1 is located to a second priority. The second priority can be higher than the cell reselection priority of the serving cell or the frequency point where the serving cell is located. After updating the priority, the related configurations of the cell #0, the cell #1 and the cell #2 corresponding to the table 1 can be updated to the table 5, and the related configurations of the cell #0, the cell #1 and the cell #2 corresponding to the table 2 can be updated to the table 6.

[0323] Table 5

[0324] Table 6

[0325] Referring to Table 5 or Table 6, in step S1601, the first terminal determines that the serving cell does not support the first type of terminal to monitor the wake-up signal, and thus the terminal type of the cell #0 supporting monitoring the wake-up signal is updated from the first type of terminal + the second type of terminal to the second type of terminal. Then, the wake-up signal cell reselection priority (corresponding to Table 5) or the original cell reselection priority (corresponding to Table 6) of the frequency point where the cell #1 is located is updated to the second priority (such as the priority value is 9 or 7). After the priority is updated, the cell reselection priority (the priority value is 9 or 7) of the frequency point where the cell #1 supporting the first type of terminal to monitor the wake-up signal is higher than the cell reselection priority (the priority value is 8 or 4) of the serving cell or the frequency point where the serving cell is located. At this time, in the case that the first terminal performs the cell reselection evaluation, the high-priority neighbor cell reselection is triggered, and in the case that the cell #1 meets the cell reselection evaluation criterion of the high-priority neighbor cell, the first terminal can reselect to the cell #1.

[0326] Based on the above manner A2, in the case that the serving cell does not support a certain terminal to monitor the wake-up signal, the terminal can update the cell reselection priority of the frequency point where the cell supporting the terminal to monitor the wake-up signal is located to the highest priority, or to the priority higher than the cell reselection priority of the serving cell or the serving frequency point. Therefore, in the subsequent cell reselection, since the priority of the serving cell or the serving frequency point is low and the cell reselection priority of the frequency point where the cell supporting the terminal to monitor the wake-up signal is located is high, the terminal can trigger the high-priority neighbor cell reselection, so as to reselect to the cell supporting the terminal to monitor the wake-up signal as much as possible, and thus the energy saving of the terminal is realized.

[0327] Manner A3, updating the cell reselection priority of the third frequency point to the third priority. The third frequency point is the frequency point where the second cell is located, and the second cell is the neighbor cell not supporting the first terminal to monitor the wake-up signal.

[0328] The third priority is the lowest priority, or the third priority is lower than the cell reselection priority of the frequency point where the first cell is located. The first cell is the neighbor cell supporting the first terminal to monitor the wake-up signal. The first cell and the lowest priority can refer to the related description of the first cell and the lowest priority in the above manner A1, which will not be repeated here.

[0329] For example, the cell reselection priority of the frequency point where the first cell is located can be the priority B before the update, or can be the second priority after the update. Here, the second cell can include the serving cell and the neighbor cell not supporting the first terminal to monitor the wake-up signal.

[0330] In a possible implementation, before step S1601, the RAN node can also indicate the cell reselection priority of the third frequency point. For example, the RAN node can send third information, and the first terminal receives the third information, where the third information indicates the cell reselection priority of the third frequency point. For example, the third information indicates that the cell reselection priority of the third frequency point is priority C.

[0331] Optionally, the cell reselection priority can be the cell reselection priority after the priority enhancement of the wake-up signal, or can be the original cell reselection priority without the priority enhancement. For details, refer to the description in the above manner A1, which will not be repeated here.

[0332] For example, the serving cell is cell #0, the neighbor cells include cell #1 and cell #2, and the related original configurations of the cell #0, the cell #1 and the cell #2 are as shown in the above table 1 or table 2. When the first terminal is a first-type terminal, that is, the serving cell does not support the first-type terminal to monitor the wake-up signal, based on the above examples of the table 1 or the table 2, the serving cell is the cell #0, the first cell is the neighbor cell (that is, the cell #1) supporting the first terminal to monitor the wake-up signal, the second cell is the cell (such as the cell #2) not supporting the first terminal to monitor the wake-up signal, and after the serving cell does not support the first-type terminal to monitor the wake-up signal, the second cell also includes the cell #0. The first terminal can update the cell reselection priority of the cell #0 and the cell #1 to a third priority. The third priority is the lowest priority (such as the priority value is 1), or the third priority is lower than the priority of the cell #1. After updating the priority, the related configurations of the cell #0, the cell #1 and the cell #2 corresponding to the table 1 can be updated to the table 7, and the related configurations of the cell #0, the cell #1 and the cell #2 corresponding to the table 2 can be updated to the table 8.

[0333] Table 7

[0334] Table 8

[0335] Referring to Table 7 or Table 8, in step S1601, the first terminal determines that the serving cell does not support the first type of terminal to monitor the wake-up signal, and thus the terminal type of the cell #0 supporting the monitoring of the wake-up signal is updated from the first type of terminal + the second type of terminal to the second type of terminal. Then, the wake-up signal cell reselection priority (corresponding to Table 7) or the original cell reselection priority (corresponding to Table 8) of the frequency point where the cell #0 and the cell #2 are located is updated to the third priority (e.g., the priority value is 1). After the priority is updated, the cell reselection priority (the priority value is 1) of the frequency point where the cell not supporting the first type of terminal to monitor the wake-up signal is lower than the cell reselection priority (the priority value is 8 or 3) of the frequency point where the cell #1 supporting the first type of terminal to monitor the wake-up signal is located. At this time, in the case of performing the cell reselection evaluation, the first terminal will trigger the high-priority neighbor cell reselection, and in the case that the cell #1 meets the cell reselection evaluation criterion of the high-priority neighbor cell, the first terminal can reselect to the cell #1.

[0336] Based on the above manner A3, in the case that the serving cell does not support a certain terminal to monitor the wake-up signal, the terminal can update the cell reselection priority of the frequency point where the cell not supporting the monitoring of the wake-up signal to the lowest priority, or to a priority lower than the priority of the frequency point where the cell supporting the terminal to monitor the wake-up signal is located. Therefore, in the subsequent cell reselection, since the cell reselection priority of the frequency point where the cell not supporting the terminal to monitor the wake-up signal is low, and the cell reselection priority of the frequency point where the cell supporting the terminal to monitor the wake-up signal is high, the terminal can trigger the high-priority neighbor cell reselection, so as to reselect to the cell supporting the terminal to monitor the wake-up signal as much as possible, and thus the energy saving of the terminal is realized.

[0337] Optionally, the first information, the second information, or the third information can be carried in the same message or in different messages, which is not limited in the present application. For example, the first information, the second information, or the third information can be carried in the same message as the indication information in the above step S1601, or can be carried in different messages from the indication information. Alternatively, the first information, the second information, or the third information can be carried in the related configuration of the wake-up signal (e.g., the first configuration information), which is not limited in the present application.

[0338] It should be noted that the above manners A1, A2, and A3 can be used independently or in combination. For example, the above manners A1 and A2 can be combined to reduce the cell reselection priority of the serving cell or the serving frequency point, and to increase the cell reselection priority of the frequency point where the neighbor cell supporting the terminal to monitor the wake-up signal is located.

[0339] For example, taking the first terminal as the first type of terminal, i.e., the serving cell does not support the first type of terminal to monitor the wake-up signal, and based on the above example of Table 2, the serving cell is cell #0, the first cell is a neighboring cell supporting the first terminal to monitor the wake-up signal, i.e., cell #1, the first terminal can update the cell reselection priority of the serving cell to the first priority, or update the cell reselection priority of the first frequency point to the first priority, and update the cell reselection priority of the frequency point where the first cell is located to the second priority. Taking the first priority as the lowest priority (the priority value is 1) and the second priority as the highest priority (the typical value is 7 (+0.8)) as an example, the related configurations of cell #0, cell #1 and cell #2 corresponding to Table 2 can be updated to Table 9 after updating the priority.

[0340] Table 9

[0341] Alternatively, the cell reselection priority of the frequency point where the cell not supporting the terminal to monitor the wake-up signal can be reduced in combination with the above manner A1 and manner A3, and the cell reselection priority of the frequency point where the neighboring cell supporting the terminal to monitor the wake-up signal can be increased.

[0342] In a possible implementation, the updated cell reselection priority described above can be set by the first terminal itself. Alternatively, the RAN node can configure the first terminal. For example, the RAN node can send fourth information indicating at least one of the updated cell reselection priority of the serving cell, the cell reselection priority of the frequency point where the serving cell is located, or the cell reselection priority of the frequency point where the neighboring cell is located. For example, the fourth information indicates at least one of the first priority, the second priority or the third priority described above.

[0343] For example, the fourth information can be carried in the system message, or can be carried in the NAS signaling, the dedicated RRC signaling, for example, the RRC reconfiguration message, the RRC release message, etc., which is not limited.

[0344] For example, the fourth information can be carried in the same message as the indication information in step S1601 described above, or the two can be carried in different messages. Alternatively, the fourth information can be carried in the related configuration of the wake-up signal (such as the first configuration information described above), which is not limited in the present application.

[0345] In summary, in the case that the serving cell does not support the terminal to monitor the wake-up signal, the terminal can reduce the cell reselection priority of the serving cell, the serving frequency, or the frequency of the cell that does not support the terminal to monitor the wake-up signal, and increase the cell reselection priority of the frequency of the neighboring cell that supports the terminal to monitor the wake-up signal. Thus, in the cell reselection, the high-priority neighboring cell reselection can be triggered, and the terminal can be reselected to the cell that supports the terminal to monitor the wake-up signal as much as possible, thereby achieving the terminal energy saving.

[0346] In the case that the signal quality of the serving cell is greater than the first threshold, the neighboring cell measurement is performed.

[0347] That is, in the case that the first terminal determines that the serving cell does not support the first terminal to monitor the wake-up signal, if the signal quality of the serving cell is greater than the first threshold, the neighboring cell measurement is performed.

[0348] For example, the signal quality of the serving cell can include S rxlev and S qual . For the intra-frequency neighboring cell, the first threshold can include S intraSearchP and S intraSearchQ ; for the inter-frequency or inter-system neighboring cell, the first threshold can include S nonIntraSearchP and S nonIntraSearchQ .

[0349] For example, performing the neighboring cell measurement can be understood as: the measurement of the neighboring cell / frequency of the neighboring cell that supports the first terminal to monitor the wake-up signal should be performed.

[0350] For example, in the case that the signal quality of the serving cell is greater than the first threshold, the neighboring cell measurement can be implemented in the following two ways:

[0351] B1, for the intra-frequency neighboring cell of the serving cell, in the case that the signal quality of the serving cell is greater than the first threshold, the intra-frequency measurement should be performed.

[0352] For example, in the case that the signal quality of the serving cell includes S rxlev and S qual , and the first threshold includes S intraSearchP and S intraSearchQ , based on the above-mentioned way B1, the following neighboring cell measurement starting rule can be applied for the intra-frequency neighboring cell:

[0353] If the serving cell satisfies S rxlev >S intraSearchP and S qual >S intraSearchQ , and if the serving cell does not support the terminal to monitor the wake-up signal, the terminal should perform the intra-frequency measurement; otherwise, the terminal can not perform the intra-frequency measurement.

[0354] If the serving cell satisfies S rxlev ≤S intraSearchP and S qual ≤S intraSearchQ , the terminal shall perform intra-frequency measurement.

[0355] For example, the serving cell does not support the terminal to monitor the wake-up signal, which can also be understood as: the terminal is disabled from the wake-up signal function, the terminal is disabled from monitoring the wake-up signal, the terminal cannot monitor the wake-up signal in the current cell, the terminal receives a system message or RRC message carrying the disable information / configuration / indication; or, the implementation that the serving cell does not support the terminal to monitor the wake-up signal can also refer to the above-mentioned related description in step S1501 that the serving cell does not support the first type of terminal to monitor the wake-up signal, which will not be repeated here.

[0356] As a possible implementation, the intra-frequency measurement to be performed can include: the measurement of the intra-frequency neighbor cell / frequency point supporting the first terminal to monitor the wake-up signal shall be performed. That is, the measurement can be performed on the intra-frequency frequency point supporting the first terminal to monitor the wake-up signal, and the measurement can not be performed on the intra-frequency frequency point not supporting the first terminal to monitor the wake-up signal.

[0357] In mode B2, for the inter-frequency neighbor cell / inter-frequency frequency point with the cell reselection priority lower than or equal to the cell reselection priority of the frequency point where the serving cell is located, and the inter-system neighbor cell / inter-system frequency point with the cell reselection priority lower than the cell reselection priority of the frequency point where the serving cell is located, the inter-frequency or inter-system frequency measurement shall be performed if the signal quality of the serving cell is greater than the first threshold.

[0358] As a possible implementation, the signal quality of the serving cell includes S rxlev and S qual , and the first threshold includes S nonIntraSearchP and S nonIntraSearchQ For example, based on this mode B2, the following neighbor cell measurement starting rules can be applied to the inter-frequency or inter-system frequency:

[0359] For the inter-frequency or inter-system frequency with the cell reselection priority higher than the cell reselection priority of the frequency point where the serving cell is located, the terminal shall perform the inter-frequency or inter-system frequency measurement of the higher priority.

[0360] For the inter-frequency neighbor cell / inter-frequency frequency point with the cell reselection priority lower than or equal to the cell reselection priority of the frequency point where the serving cell is located, and the inter-system neighbor cell / inter-system frequency point with the cell reselection priority lower than the cell reselection priority of the frequency point where the serving cell is located:

[0361] If the serving cell satisfies S rxlev >S nonIntraSearchP and S qual >S nonIntraSearchQand if the serving cell does not support the terminal to monitor the wake-up signal, the terminal should perform the intra-frequency measurement; otherwise, the terminal can choose not to perform the inter-frequency or inter-system measurement with the same or lower priority;

[0362] if the serving cell satisfies S rxlev ≤ S nonIntraSearchP and S qual ≤ S nonIntraSearchQ , the terminal should perform the inter-frequency or inter-system measurement with the same or lower priority.

[0363] For example, the implementation that the serving cell does not support the terminal to monitor the wake-up signal can refer to the related description in the above manner B1, which will not be described here.

[0364] As a possible implementation, the inter-frequency or inter-system measurement with the same or lower priority that should be performed can include: the measurement of the inter-frequency or inter-system frequency point supporting the first terminal to monitor the wake-up signal should be performed. That is, the measurement can be performed on the inter-frequency or inter-system frequency point supporting the first terminal to monitor the wake-up signal, and the measurement can not be performed on the inter-frequency or inter-system frequency point not supporting the first terminal to monitor the wake-up signal.

[0365] Based on the above manner B, in the case that the serving cell does not support the terminal to monitor the wake-up signal, even if the signal quality of the serving cell is good, the terminal can start the neighbor cell measurement, for example, the neighbor cell measurement on the frequency point supporting the terminal to monitor the wake-up signal can be started, so that in the case that there is a neighbor cell satisfying the cell reselection evaluation criterion, the terminal can be reselected to the neighbor cell, and the terminal can continue to monitor the wake-up signal in the neighbor cell, thereby realizing the terminal energy saving.

[0366] Manner C: performing the cell reselection evaluation according to the first frequency point list, the cells on the frequency points in the first frequency point list support the first terminal to monitor the wake-up signal.

[0367] That is, in the case that the first terminal determines that the serving cell does not support the first terminal to monitor the wake-up signal, the cell reselection evaluation can be performed according to the first frequency point list.

[0368] As a possible implementation, the first frequency point list includes at least one frequency point. The frequency points in the first frequency point list can be the same frequency frequency points or inter-frequency frequency points of the service frequency point. The same frequency frequency points and the inter-frequency frequency points can be carried in the same frequency point list, or can be carried in different frequency point lists, which is not limited.

[0369] As a possible implementation, the first frequency point list can be sent by the RAN node. For example, the RAN node can send the fifth information, and the first frequency point list can be included in the fifth information. Correspondingly, the first terminal receives the fifth information, thereby obtaining the first frequency point list.

[0370] Optionally, the fifth information can further comprise a second frequency point list and / or a third frequency point list. The cells on the frequency points in the second frequency point list support the wake-up signal. The cells on the frequency points in the third frequency point list do not support the first terminal to monitor the wake-up signal.

[0371] For example, in an embodiment of the present application, the first frequency point list can also be referred to as a white list, the second frequency point list can also be referred to as a gray list, and the third frequency point list can also be referred to as a black list. Of course, the first frequency point list, the second frequency point list, or the third frequency point list can also have other names, which are not limited in the present application.

[0372] For example, the cells supporting the wake-up signal can refer to the related description in the above manner A1, which will not be repeated here. The second frequency point list can comprise at least one frequency point. The cells on the frequency points in the second frequency point list support the wake-up signal, but whether the cells support the first terminal to monitor the wake-up signal can not be limited. That is, the cells on the frequency points in the second frequency point list can support the first terminal to monitor the wake-up signal, or can not support the first terminal to monitor the wake-up signal.

[0373] For example, the third frequency point list can comprise the frequency point where the serving cell is located. Further, the third frequency point list can comprise the identification information of the serving cell, such as comprising the physical cell identifier (PCI) of the serving cell, indicating that the serving cell on the frequency point does not support the first terminal to monitor the wake-up signal. The cells other than the serving cell on the frequency point can support the first terminal to monitor the wake-up signal, or can not support the first terminal to monitor the wake-up signal.

[0374] In addition, in the case where the third frequency point list comprises the identification information of the serving cell, it can also be implicitly indicated that the serving cell does not support the first terminal to monitor the wake-up signal. That is, the RAN node can implicitly indicate that some cells / frequency points do not support the first terminal to monitor the wake-up signal by issuing the black list.

[0375] For example, the fifth information can be carried in a system message, or can be carried in terminal-specific signaling such as NAS signaling, RRC signaling, which is not limited, such as RRC reconfiguration message or RRC release message, etc.

[0376] For example, the fifth information can be carried in the same message as the indication information in the above step S1601, or the two can be carried in different messages. Alternatively, the fifth information can be carried in the related configuration of the wake-up signal (such as the above first configuration information), which is not limited in the present application.

[0377] As a possible implementation, the first terminal performing cell reselection evaluation according to the first frequency point list can include: the first terminal performing measurement on the frequency points in the first frequency point list, and if there is a cell satisfying the cell reselection evaluation criterion on the frequency points in the first frequency point list, the first terminal can reselect to the cell.

[0378] In the case that there is a cell satisfying the cell reselection evaluation criterion on the frequency points in the first frequency point list, even if there is a second frequency point list, the measurement on the frequency points in the second frequency point list can not be performed. In the case that there is no cell satisfying the cell reselection evaluation criterion on the frequency points in the first frequency point list, if there is a second frequency point list, the measurement on the frequency points in the second frequency point list can be performed, and in the case that there is a cell satisfying the cell reselection evaluation criterion on the frequency points in the second frequency point list and supporting the first terminal monitoring the wake-up signal, the first terminal can reselect to the cell.

[0379] Optionally, in the case that there is no cell satisfying the cell reselection evaluation criterion on the frequency points in the first frequency point list and the frequency points in the second frequency point list, or in the case that there is no cell satisfying the cell reselection evaluation criterion on the frequency points in the first frequency point list and there is no second frequency point list, the first terminal can perform cell reselection evaluation according to the cell reselection priority. That is, the priority of performing cell reselection evaluation based on the white list / gray list is higher than the priority of performing cell reselection evaluation based on the cell reselection priority.

[0380] Optionally, in the case that there is a third frequency point list, whether there is a cell satisfying the cell reselection evaluation criterion on the frequency points in the first frequency point list and / or the second frequency point list, the first terminal does not perform measurement on the frequency points in the third frequency point list.

[0381] Based on the above manner C, in the case that the serving cell does not support the terminal monitoring the wake-up signal, the frequency point list supporting the terminal monitoring the wake-up signal can be configured for the terminal, so that the terminal can perform measurement on the frequency points in the frequency point list, and thus can reselect to the cell satisfying the cell reselection evaluation criterion on the frequency points based on the measurement result. Since the cell on the frequency point supports the terminal monitoring the wake-up signal, after the terminal reselects to the cell on the frequency point, the terminal can monitor the wake-up signal in the cell, thereby realizing terminal energy saving.

[0382] Manner D, performing cell reselection evaluation according to a cell list A. The cells in the cell list A support the first terminal monitoring the wake-up signal.

[0383] That is, in the case that the first terminal determines that the serving cell does not support the first terminal monitoring the wake-up signal, the cell reselection evaluation can be performed according to the cell list A.

[0384] It should be noted that the cell list A can also have other names, such as a second cell list, and the like, and can be replaced with each other, and the present application does not make specific limitations thereto.

[0385] As a possible implementation, the cell list A includes at least one cell. The cell in the cell list A can be a same-frequency neighbor cell or a different-frequency neighbor cell. The same-frequency neighbor cell or the different-frequency neighbor cell can be carried in the same cell list or can be carried in different cell lists, which is not limited.

[0386] As a possible implementation, the cell list A can be sent by the RAN node. For example, the RAN node can send sixth information, which can include the cell list A. Correspondingly, the first terminal receives the sixth information, thereby obtaining the cell list A.

[0387] Optionally, the sixth information can also include a cell list B and / or a cell list C. The cell in the cell list B supports the wake-up signal. The cell in the cell list C does not support the first terminal to monitor the wake-up signal. For example, the cell list B can also be referred to as a third cell list, and the cell list C can also be referred to as a fourth cell list, and of course can have other names, which is not limited.

[0388] For example, in the embodiments of the present application, the cell list A can also be referred to as a white list, the cell list B can also be referred to as a gray list, and the cell list C can also be referred to as a black list. Of course, the cell list A, the cell list B, or the cell list C can also have other names, which is not limited by the present application.

[0389] For example, the cell supporting the wake-up signal can refer to the related description in the above manner A1, which will not be repeated here. The cell list B can include at least one cell. The cell in the cell list B supports the wake-up signal, but whether the cell supports the first terminal to monitor the wake-up signal can not be limited. That is, the cell in the cell list B can support the first terminal to monitor the wake-up signal, or can not support the first terminal to monitor the wake-up signal.

[0390] For example, the cell list C can include identification information of the serving cell, such as the PCI of the serving cell, and the serving cell does not support the first terminal to monitor the wake-up signal. The cell list C can also include identification information of other cells that do not support the first terminal to monitor the wake-up signal.

[0391] In addition, in the case where the cell list C includes the identification information of the serving cell, it can also be implicitly indicated that the serving cell does not support the first terminal to monitor the wake-up signal. That is, the RAN node can implicitly indicate that some cells do not support the first terminal to monitor the wake-up signal by issuing a black list.

[0392] For example, the sixth information can be carried in a system message, or can be carried in terminal-specific signaling, such as NAS signaling, RRC signaling, which is not limited, for example, can be an RRC reconfiguration message or an RRC release message.

[0393] For example, the sixth information can be carried in the same message as the indication information in step S1601 described above, or the two can be carried in different messages. Alternatively, the sixth information can be carried in the related configuration of the wake-up signal (such as the first configuration information described above), which is not limited in the present application.

[0394] As a possible implementation, the first terminal performs cell reselection evaluation according to the cell list A, which can include: the first terminal performs measurement on the cells in the cell list A, and if there is a cell in the cell list A that meets the cell reselection evaluation criteria, the first terminal can reselect to the cell.

[0395] In the case where there is a cell in the cell list A that meets the cell reselection evaluation criteria, even if there is a cell list B, no measurement can be performed on the cells in the cell list B. In the case where there is no cell in the cell list A that meets the cell reselection evaluation criteria, if there is a cell list B, measurement can be performed on the cells in the cell list B, and in the case where there is a cell in the cell list B that meets the cell reselection evaluation criteria and supports the first terminal to monitor the wake-up signal, the first terminal can reselect to the cell.

[0396] Optionally, in the case where there is no cell in the cell list A and the cell list B that meets the cell reselection evaluation criteria, or in the case where there is no cell in the cell list A that meets the cell reselection evaluation criteria and there is no cell list B, the first terminal can perform cell reselection evaluation according to the cell reselection priority. That is, the priority of performing cell reselection evaluation based on the white list / gray list is higher than the priority of performing cell reselection evaluation based on the cell reselection priority.

[0397] Optionally, in the case where there is a cell list C, regardless of whether there is a cell in the cell list A and / or the cell list B that meets the cell reselection evaluation criteria, the first terminal does not perform measurement on the cells in the cell list C.

[0398] Based on the above manner D, in the case where the serving cell does not support the terminal to monitor the wake-up signal, the terminal can be configured with a cell list that supports the terminal to monitor the wake-up signal, so that the terminal can perform measurement on the cells in the cell list, and thus can reselect to a cell in the cell list that meets the cell reselection evaluation criteria based on the measurement result. Since the cell supports the terminal to monitor the wake-up signal, after the terminal reselects to the cell, the terminal can monitor the wake-up signal in the cell, thereby achieving terminal energy saving.

[0399] In addition to the method shown in FIG. 15 and FIG. 16, the present application also provides a communication method, which can be applied to the CU DU separated architecture, or can be applied to the O-RAN system. As shown in FIG. 17, the communication method comprises the following steps:

[0400] S1701, the terminal sends first indication information to the core network element. Correspondingly, the core network element receives the first indication information from the terminal.

[0401] Exemplarily, the core network element can be an AMF network element, and of course can also be other core network elements, which are not limited. The terminal can send the first indication information to the core network element through the RAN node, for example, the terminal can send the first indication information to the core network element through the DU and the CU.

[0402] The first indication information indicates the type of the terminal, or indicates the type of the first receiver supported by the terminal. The first receiver is used for monitoring the wake-up signal, which can be referred to the foregoing related description of the first receiver, and will not be described here.

[0403] Exemplarily, the type of the terminal is a first type or a second type. The terminal of the first type, or the terminal of the first type, can be understood as a first type terminal; the terminal of the second type, or the terminal of the second type, can be understood as a second type terminal.

[0404] Exemplarily, the type of the first receiver is a first type or a second type. The first receiver of the first type, or the first receiver of the first type, can be understood as a first type terminal supporting the first type of the first receiver, or a terminal supporting the first type of the first receiver. The first receiver of the second type, or the first receiver of the second type, can be understood as a second type terminal supporting the second type of the first receiver, or a terminal supporting the second type of the first receiver.

[0405] Exemplarily, the first receiver of the first type can also be understood as a first type WUR or OOK receiver; the first receiver of the second type can also be understood as a second type WUR or OFDM receiver. The foregoing related description of the first type WUR and the second type WUR can be referred to, and will not be described here.

[0406] Exemplarily, the first type terminal or the first type first receiver supports envelope detection and does not support correlation detection; the second type terminal or the second type first receiver supports correlation detection. The foregoing related description of the first type terminal and the second type terminal, and the first type WUR and the second type WUR can be referred to, and will not be described here.

[0407] As a possible implementation, in case that the first indication information indicates the type of the first receiver supported by the terminal, the first indication information can indicate that the type of the first receiver supported by the terminal is the first type, or the second type, or both. For example, the first indication information can be carried by an information element (IE).

[0408] For example, the form of the information element can be a string for enumerating that the type of the first receiver supported by the terminal is the first type, or the second type, or both. For example, the information element can be represented as ENUMERATED(OOK, OFDM, Both...), or ENUMERATED(Type1, Type2, Both...).

[0409] For another example, the form of the information element can be a two-bit bit string (BIT STRIING). The two bits can be indicated separately or in bits, for example, the first bit indicates whether the terminal supports the first type of the first receiver or the OOK receiver, and the second bit indicates whether the terminal supports the second type of the first receiver or the OFDM receiver. Or, the two bits can be jointly indicated, for example, each value of the two bits indicates a type of receiver, such as 00 indicates that the terminal supports the first type of the first receiver or the OOK receiver, 01 indicates that the terminal supports the second type of the first receiver or the OFDM receiver, 10 indicates that the terminal supports the first type and the second type of the first receiver, or supports the OOK receiver and the OFDM receiver, and 11 is default, indicating no information.

[0410] As another possible implementation, in case that the first indication information indicates the type of the first receiver supported by the terminal, the first indication information can indicate that the type of the first receiver supported by the terminal is the first type, or not the first type; or indicate that the type of the first receiver supported by the terminal is the second type, or not the second type; or indicate that the type of the first receiver supported by the terminal is the OOK receiver, or not the OOK receiver; or indicate that the type of the first receiver supported by the terminal is the OFDM receiver, or not the OFDM receiver. For example, the first indication information can be carried by an information element.

[0411] For example, the form of the information element can be a string for enumeration indicating whether the type of the first receiver supported by the terminal is the first type, or is the second type, or is the OOK receiver, or is the OFDM receiver. For example, the information element can be represented as ENUMERATED(True...), in which case, if the information element is set to True, it indicates that the type of the first receiver supported by the terminal is the first type, or is the second type, or is the OOK receiver, or is the OFDM receiver, or is not the first type, or is not the second type, or is not the OOK receiver, or is not the OFDM receiver. Alternatively, the information element can be represented as ENUMERATED(OOK, not OOK...), or ENUMERATED(OFDM, not OFDM...), indicating that the type of the first receiver supported by the terminal is the OOK receiver, or is not the OOK receiver, or indicating that the type of the first receiver supported by the terminal is the OFDM receiver, or is not the OFDM receiver.

[0412] For another example, the form of the information element can be a one-bit bit string (BIT STRIING), in which case, if the bit is set to 1, it indicates that the type of the first receiver supported by the terminal is the first type, or is the second type, or is the OOK receiver, or is the OFDM receiver; if the bit is set to 0, it indicates that the type of the first receiver supported by the terminal is not the first type, or is not the second type, or is not the OOK receiver, or is not the OFDM receiver.

[0413] As another possible implementation, the first indication information can be carried by two information elements. For example, information element 1 indicates whether the type of the first receiver supported by the terminal is the first type, or whether the terminal supports the OOK receiver, and information element 2 indicates whether the type of the first receiver supported by the terminal is the second type, or whether the terminal supports the OFDM receiver.

[0414] For example, the format of information element 1 can be ENUMERATED(supported / true...), and the format of information element 2 can be ENUMERATED(supported / true...). In the case where information element 1 is set to supported or true, it indicates that the terminal supports the first type of first receiver, or supports the OOK receiver; in the case where information element 2 is set to supported or true, it indicates that the terminal supports the second type of first receiver, or supports the OFDM receiver.

[0415] For example, the information element 1 and the information element 2 can be a bit string (BIT STRIING) of one bit. For example, when the one bit of the information element 1 is set to 1, it indicates that the terminal supports the first receiver of the first type, or supports the OOK receiver; when the one bit of the information element 1 is set to 0, it indicates that the terminal does not support the first receiver of the first type, or does not support the OOK receiver; when the one bit of the information element 2 is set to 1, it indicates that the terminal supports the first receiver of the second type, or supports the OFDM receiver; when the one bit of the information element 2 is set to 0, it indicates that the terminal does not support the first receiver of the second type, or does not support the OFDM receiver.

[0416] The first indication information indicates the implementation of the type of the terminal, and the implementation of the type of the terminal supported by the terminal can be referred to the implementation of the first receiver type indicated by the first indication information, which is not described herein again.

[0417] As a possible implementation, the first indication information can be carried in the UE-NR-Capability->UE-RadioPagingInfo information element in the UECapabilityInformation message, for example, one or two information elements carrying the first indication information can be information elements in the UE-RadioPagingInfo information element. At this time, the CU can carry the first indication information in the ue-RadioPagingInfo information element of the UERadioPagingInformation message and send it to the core network element. The UERadioPagingInformation message can be generated and sent to the CU by the DU, or can be generated by the CU.

[0418] As another possible implementation, the first indication information can be carried in the UE-NR-Capability information element in the UECapabilityInformation message, for example, one or two information elements carrying the first indication information can be information elements in the UE-NR-Capability information element. At this time, the information element carrying the first indication information and the UE-RadioPagingInfo information element are at the same level. At this time, the CU can carry the first indication information in the UERadioPagingInformation message and send it to the core network element, and the first indication information can be at the same level as the ue-RadioPagingInfo information element, that is, the UERadioPagingInformation message includes an information element at the same level as the ue-RadioPagingInfo information element for carrying the first indication information. The UERadioPagingInformation message can be generated and sent to the CU by the DU, or can be generated by the CU.

[0419] S1702, the core network element sends a paging message to the first RAN node. Correspondingly, the first RAN node receives the paging message from the core network element.

[0420] For example, the first RAN node can be a CU, or can be a RAN node capable of implementing the function of the CU, and the first RAN node is taken as the CU for example in FIG. 17.

[0421] The paging message includes the type of the terminal being paged, or the type of the first receiver supported by the terminal being paged. For example, the type of the terminal being paged, or the type of the first receiver supported by the terminal being paged can be carried in the UERadioPagingInformation message in the paging message.

[0422] Optionally, the UERadioPagingInformation message in the paging message can also carry other air interface capabilities of the terminal being paged, which is not limited in the present application.

[0423] S1703, the first RAN node sends the paging message to the second RAN node. Correspondingly, the second RAN node receives the paging message from the first RAN node.

[0424] For example, the second RAN node can be a DU, or can be a RAN node capable of implementing the function of the DU, and the second RAN node is taken as the DU for example in FIG. 17.

[0425] The paging message includes second indication information, which indicates the type of the terminal being paged, or indicates the type of the first receiver supported by the terminal being paged. For example, the second indication information can be carried in the UE Paging Capability information element in the paging message. The implementation of the second indication information can refer to the related description of the first indication information, which will not be repeated here.

[0426] Optionally, the paging message can also include a paging cell list. The paging cell list can include the identity of at least one cell. The at least one cell is a cell that needs to send the paging message, or in other words, needs to page the terminal in the at least one cell.

[0427] S1704, the second RAN node sends or does not send a wake-up signal in the first cell according to the type of the terminal being paged or the type of the first receiver supported by the terminal being paged.

[0428] wherein the first cell is any cell in the list of paging cells. That is, for each cell in the list of paging cells, it can be determined whether to transmit or not to transmit the wake-up signal in the cell according to the type of the paged terminal or the type of the first receiver supported by the terminal. In addition, the first cell is a cell managed by the second RAN node.

[0429] As one possible implementation, the first cell or the first frequency (i.e. the frequency on which the first cell is located) supports the wake-up signal but does not support the first type of terminal monitoring the wake-up signal:

[0430] If the type of the paged terminal is the first type or the type of the first receiver supported by the terminal is the first type, the second RAN node does not transmit the wake-up signal in the cell on the first cell or the first frequency.

[0431] If the type of the paged terminal is the second type or the type of the first receiver supported by the terminal is the second type, the second RAN node transmits the wake-up signal in the cell on the first cell or the first frequency. Exemplarily, the wake-up signal can be generated by the above-mentioned way one, way two, or way three.

[0432] As another possible implementation, in the case that the first cell or the first frequency supports the wake-up signal and supports the first type of terminal monitoring the wake-up signal:

[0433] If the type of the paged terminal or the type of the first receiver supported by the paged terminal is the first type or the second type, the second RAN node transmits the wake-up signal in the first cell. That is, no matter the type of the paged terminal or the type of the first receiver supported by the terminal, the second RAN node transmits the wake-up signal in the cell on the first cell or the first frequency. Exemplarily, the wake-up signal can be generated by the above-mentioned way one or way three, and in the case that the paged terminal is the second type of terminal, it can also be generated by way two.

[0434] As yet another possible implementation, in the case that the first cell or the first frequency does not support the wake-up signal, no matter the type of the paged terminal or the type of the first receiver supported by the terminal, the second RAN node does not transmit the wake-up signal in the cell on the first cell or the first frequency.

[0435] In addition, the second RAN node can transmit the paging message in the cell in the list of paging cells to perform paging of the terminal.

[0436] Based on the scheme, the DU can determine whether to send or not to send the wake-up signal in a cell based on the type of the terminal being paged or the type of the first receiver supported by the terminal. For example, in the case where the cell supports the wake-up signal but does not support the first type of terminal to monitor the wake-up signal, if the first type of terminal is being paged, the DU can not send the wake-up signal in the cell, because the cell does not support the first type of terminal to monitor the wake-up signal, i.e., the wake-up signal of the cell can be generated according to the above-mentioned manner two, at this time, even if the DU sends the wake-up signal in the cell, the first type of terminal in the cell cannot monitor the wake-up signal, so the main receiver of the first type of terminal cannot be woken up, resulting in waste of network side resources. In addition, if the DU sends the wake-up signal in the cell, it will wake up the second type of terminal belonging to the same terminal group as the terminal being paged, which will unnecessarily wake up the second type of terminal, increase the false alarm probability of the second type of terminal, and reduce the energy saving gain.

[0437] That is, in the case where a certain cell supports the wake-up signal but does not support the first type of terminal to monitor the wake-up signal, if the first type of terminal is being paged, the DU does not send the wake-up signal in the cell, which can save network side resources and avoid resource waste. In addition, it can also reduce the false alarm probability of part of the second type of terminal and increase the energy saving gain of the second type of terminal.

[0438] For another example, in the case where a certain cell supports the wake-up signal but does not support the first type of terminal to monitor the wake-up signal, if the second type of terminal is being paged, the DU sends the wake-up signal in the cell. Since the cell does not support the first type of terminal to monitor the wake-up signal, the wake-up signal can be generated according to the above-mentioned manner two, so that the wake-up signal will not be received by the first type of terminal in the cell, i.e., the second type of terminal can be accurately woken up and the first type of terminal will not be falsely alarmed.

[0439] In the above scheme, the CU can indicate the type of the terminal being paged or the type of the first receiver supported by the terminal to the DU in the paging message, so that the DU can determine whether to send or not to send the wake-up signal in a cell according to the type. In addition, the present application also provides a communication method, in which the DU can report to the CU whether the cell / frequency point supports the wake-up signal or whether the first type of terminal / second type of terminal monitors the wake-up signal, and the CU can add or delete the cells in the paging cell list based on the information reported by the DU. For example, as shown in FIG. 18, the communication method can include the following steps:

[0440] S1801, the terminal sends first indication information to a core network element. Correspondingly, the core network element receives the first indication information from the terminal.

[0441] The first indication information indicates a type of the terminal or a type of a first receiver supported by the terminal. For details, refer to the description of step S1701.

[0442] S1802, the second RAN node sends first information to the first RAN node. Correspondingly, the first RAN node receives the first information from the second RAN node.

[0443] For example, the first RAN node can be a CU or a RAN node capable of implementing the function of the CU, and the first RAN node is taken as the CU for illustration in FIG. 18. The second RAN node can be a DU or a RAN node capable of implementing the function of the DU, and the second RAN node is taken as the DU for illustration in FIG. 18.

[0444] The first information indicates a wake-up signal enabling condition of at least one cell / frequency point, which can include at least one of the following: whether the at least one cell / frequency point supports the wake-up signal, whether the first type of terminal supports monitoring the wake-up signal, or whether the second type of terminal supports monitoring the wake-up signal. For example, the at least one cell can be a cell managed by the second RAN node, and the at least one frequency point can be a frequency point supported by the second RAN node.

[0445] For example, the second RAN node can send the first information in a connection establishment process between the second RAN node and the first RAN node, for example, by carrying the first information in an F1 SETUP REQUEST message. Alternatively, the second RAN node can send the first information in a DU reconfiguration process, for example, by carrying the first information in a GNB-DU CONFIGURATION UPDATE message, such as carrying the wake-up signal enabling condition of a certain cell in the Served Cell Information information element corresponding to the cell.

[0446] For example, the first information can indicate the wake-up signal enabling condition of the at least one cell / frequency point by means of string enumeration or bit string indication. For details, refer to the description of the first indication information in step S1701.

[0447] S1803, the core network element sends a paging message to the first RAN node. Correspondingly, the first RAN node receives the paging message from the core network element.

[0448] The paging message includes a first paging cell list. The first paging cell list can include an identity of at least one cell. The at least one cell is a cell that needs to send the paging message, or in other words, a cell that needs to page a terminal in the at least one cell.

[0449] S1804, the first RAN node sends a paging message to the second RAN node. Correspondingly, the second RAN node receives the paging message from the first RAN node.

[0450] The paging message includes a second paging cell list. The second paging cell list is determined according to the first paging cell list and the first information. For example, in the case where the paging message in step S1803 above is used to page the third type of terminal in the cells in the first paging cell list, if the first cell does not support the third type of terminal to monitor the wake-up signal, or the first cell does not support the wake-up signal, the second paging cell list does not include the first cell. That is, the first cell can be deleted from the first paging cell list to obtain the second paging cell list.

[0451] The third type of terminal is the first type of terminal or the second type of terminal. That is, in the case where the paging message in step S1803 above is used to page the first type of terminal in the cells in the first paging cell list, if the first cell does not support the first type of terminal to monitor the wake-up signal, or the first cell does not support the wake-up signal, the second paging cell list does not include the first cell. Or, in the case where the paging message is used to page the second type of terminal in the cells in the first paging cell list, if the first cell does not support the second type of terminal to monitor the wake-up signal, or the first cell does not support the wake-up signal, the second paging cell list does not include the first cell.

[0452] S1805, the second RAN node sends a wake-up signal in the cells in the second paging cell list.

[0453] In addition, the second RAN node also sends a paging message in the cells in the second paging cell list to page the terminal.

[0454] Based on the scheme, the CU can reasonably adjust the paging cell list based on the enabling condition of the wake-up signal of at least one cell / frequency point reported by the DU. For example, in the case that a certain cell does not support a certain type of terminal to monitor the wake-up signal, if the terminal of the type is paged, the CU can delete the cell from the paging cell list, so that the DU will not send the wake-up signal in the cell. The reason is that the cell does not support the terminal of the type to monitor the wake-up signal. Even if the DU sends the wake-up signal in the cell, the terminal of the type in the cell cannot monitor the wake-up signal, so the main receiver of the terminal of the type cannot be awakened, resulting in waste of network resources. In addition, if the DU sends the wake-up signal in the cell, it will awaken other terminals of the same type as the paged terminal (the cell supports the other terminals of the type to monitor the wake-up signal), which will unnecessarily awaken the other terminals of the type, increase the false alarm probability of the other terminals of the type, and reduce the energy saving gain. That is, based on the above scheme, network resources can be saved, and resource waste can be avoided. In addition, the false alarm probability of part of the terminals can be reduced, and the energy saving gain of the part of the terminals can be increased.

[0485] All the related contents of the steps involved in the above method embodiments can be referred to the function description of the corresponding functional modules, which will not be repeated here.

[0486] In the present application, the communication apparatus 190 can be in the form of an integrated manner to present various functional modules. The "module" here can refer to a specific application-specific integrated circuit (ASIC), a circuit, a processor and a memory executing one or more software or firmware programs, an integrated logic circuit, and / or other devices that can provide the above functions.

[0487] In some embodiments, when the communication apparatus 190 in FIG. 19 is a chip or a chip system, the functions / implementation processes of the transceiver module 1902 can be implemented through the input / output interface (or the communication interface) of the chip or the chip system, and the functions / implementation processes of the processing module 1901 can be implemented through the processor (or the processing circuit) of the chip or the chip system.

[0488] Since the communication apparatus 190 provided by the present embodiment can execute the above method, the technical effects that can be obtained thereby can be referred to the above method embodiments, which will not be repeated here.

[0489] As one possible product form, the terminal or RAN node described in embodiments of the application can be implemented using one or more field programmable gate arrays (FPGAs), programmable logic devices (PLDs), controllers, state machines, gated logic, discrete hardware components, any other suitable circuitry, or any combination thereof capable of implementing the various functions described throughout this application.

[0490] As another possible product form, the terminal or RAN node described in embodiments of the application can be implemented by a general bus architecture. For ease of illustration, refer to FIG. 20, which is a structural diagram of a communication apparatus 200 provided in embodiments of the application, the communication apparatus 200 including a processor 2001 and a transceiver 2002. The communication apparatus 200 can be a terminal, or a chip or chip system therein; or the communication apparatus 200 can be a RAN node, or a chip or chip system or module therein. FIG. 20 only shows the main components of the communication apparatus 200. In addition to the processor 2001 and the transceiver 2002, the communication apparatus can further include a memory 2003, a power module, and an input / output device (not shown in FIG. 20).

[0491] Optionally, the processor 2001 is mainly used for processing communication protocols and communication data, and controlling the entire communication apparatus, executing software programs, processing data of the software programs, so as to implement the methods provided in the method embodiments described above. The memory 2003 is mainly used for storing software programs and data. The transceiver 2002 can include radio frequency circuitry and an antenna, the radio frequency circuitry being mainly used for conversion between baseband signals and radio frequency signals, and processing of the radio frequency signals. The radio frequency circuitry can include, for example, an MR and an LP-WUR. The antenna is mainly used for transceiving radio frequency signals in the form of electromagnetic waves. The input / output device, such as a touch screen, a display screen, a keyboard, etc., is mainly used for receiving data input by a user and outputting data to the user.

[0492] Optionally, the processor 2001, the transceiver 2002, and the memory 2003 can be connected through a communication bus.

[0493] When the communication device is powered on, the processor 2001 can read the software program in the memory 2003, execute the instructions of the software program, and process the data of the software program. When data needs to be transmitted wirelessly, the processor 2001 performs baseband processing on the data to be transmitted, and outputs the baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal, and transmits the radio frequency signal in the form of electromagnetic waves through the antenna. When data is transmitted to the communication device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 2001. The processor 2001 converts the baseband signal into data and processes the data.
