[0001] The present application relates to the field of communication technology, and more specifically, to a method, terminal device and network device for wireless communication. Background Art

[0002] To reduce the power consumption of terminal devices, a wake-up receiver (WUR) is introduced to receive low-power wake-up signals, so that the terminal device can turn off the main receiver. However, according to the existing cell selection or cell reselection strategy, after cell selection or cell reselection, the cell where the terminal device resides may not support low-power wake-up signals. In this case, the terminal device cannot use the WUR in the cell where it resides and turns off the main receiver, resulting in the terminal device's power consumption still being high.

[0032] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0033] For ease of understanding, the communication process involved in the embodiments of the present application is introduced below.

[0034] Radio resource control (RRC) state and mobility management

[0035] Currently, the protocol defines three RRC states of terminal devices: RRC connected (RRC_connected) state, RRC idle (RRC-idle) state and RRC inactive (RRC-inactive) state.

[0036] The RRC connection state may refer to the state in which the terminal device is in when the RRC release is not performed after the random access process is completed. An RRC connection exists between the terminal device and a network device (e.g., an access network device). In the RRC connection state, the terminal device can transmit data with the network device, such as downlink data transmission and / or uplink data transmission. Alternatively, the terminal device can also transmit terminal device-specific data channels and / or control channels with the network device to transmit specific information or unicast information of the terminal device.

[0037] In the RRC connected state, the network device can determine the cell-level location information of the terminal device, that is, the network device can determine the cell to which the terminal device belongs. In the RRC connected state, after the terminal device moves, such as from one cell to another, the network device can control the terminal device to perform cell handover. Therefore, it can be seen that the mobility management of the terminal device in the RRC connected state may include cell handover. In addition, the mobility management of the terminal device in the RRC connected state can be controlled by the network device. Accordingly, the terminal device can switch to a designated cell according to the instructions issued by the network device.

[0038] The RRC idle state refers to the state of the terminal device when it is resident in a cell but is not performing random access. The terminal device usually enters the RRC idle state after being powered on or after RRC is released. In the RRC idle state, there is no RRC connection between the terminal device and the network device (such as the resident network device), the network device does not store the context of the terminal device, and no connection is established between the network device and the core network for the terminal device. If the terminal device needs to enter the RRC connected state from the RRC idle state, it is necessary to initiate the RRC connection establishment process.

[0039] In the RRC idle state, the core network (CN) can send a paging message to the terminal device, that is, the paging process can be triggered by the CN. Optionally, the paging area can also be configured by the CN. In some cases, for a terminal device in the RRC idle state, when the terminal device moves (for example, from one cell to another), the terminal device can initiate a cell reselection process. In other cases, for a terminal device in the RRC idle state, when the terminal device needs to access a cell, the terminal device can initiate a cell selection process. That is, the mobility management of the terminal device in the RRC idle state may include cell reselection and / or cell selection.

[0040] The RRC inactive state is defined to reduce air interface signaling, quickly restore wireless connections, and quickly resume data services. The RRC inactive state is a state between the connected and idle states. A terminal device previously entered the RRC connected state and then released the RRC connection with the network device, but the network device retained the terminal device's context. Furthermore, the connection established between the network device and the core network for the terminal device is not released. This means that the user plane and control plane bearers between the RAN and CN are still maintained, indicating a CN-NR connection.

[0041] In the RRC inactive state, the RAN can send a paging message to the terminal device, that is, the paging process can be triggered by the RAN. The RAN-based paging area is managed by the RAN, and the network equipment can know the location of the terminal device based on the RAN paging area level.

[0042] In some cases, for a terminal device in an RRC inactive state, when the terminal device moves (for example, from one cell to another), the terminal device may initiate a cell reselection process. In other cases, for a terminal device in an RRC inactive state, when the terminal device needs to access a cell, the terminal device may initiate a cell selection process. In other words, the mobility management of a terminal device in an RRC inactive state may include cell reselection and / or cell selection.

[0043] Cell selection, cell handover, and cell reselection can all be performed based on RRM measurement results. For example, when the RRM measurement result exceeds the RRM measurement threshold, the terminal device can perform cell selection, cell handover, or cell reselection. The following describes the cell selection and cell reselection processes.

[0044] Cell selection

[0045] Cell selection generally occurs after PLMN selection, allowing the terminal device to quickly select a cell (also known as a "target cell") with satisfactory signal quality within the selected PLMN for residency. In the embodiments of this application, the cell selection target may be referred to as a "candidate cell." Currently, cell selection can be divided into initial cell selection and stored information cell selection.

[0046] For initial cell selection, a terminal device typically has no prior information to help it identify a specific system frequency. Therefore, the terminal device must scan all frequency bands based on its capabilities to find a suitable cell to reside in. On each frequency, the terminal device only needs to search for the cell with the best signal quality. Once a suitable cell is found, the terminal device selects it and resides in it.

[0047] For stored information cell selection, the terminal device has stored information related to carrier frequencies during previous access processes. This information may also include some cell parameter information, for example, from previously received measurement control information or previously camped / detected cells. The terminal device will prioritize cells with relevant information for measurement. Once a suitable cell appears, the terminal device can select and camp on that cell. If none of the cells with stored information are suitable, the terminal device can also initiate an initial cell selection process.

[0048] During the cell selection process, the terminal device needs to measure the signal quality of candidate cells to determine whether they meet the residency criteria. In some implementations, the measurement criteria for cell selection can be called the S criterion. When the signal quality of a candidate cell meets the S criterion, it is selected as the resided cell.

[0049] Cell reselection

[0050] As described above, when a terminal device is in an idle or inactive state, it can continuously reselect a cell in order to reside in a cell with a higher priority or better signal quality (also known as a "target cell"). In some implementations, the network device can control the frequency on which the terminal device resides by setting the priority of different frequencies. Accordingly, after the terminal device selects an appropriate frequency based on the priority corresponding to the frequency, it can select a cell with better signal quality on that frequency to provide better service.

[0051] In the embodiments of the present application, the objects of cell reselection may be referred to as "candidate cells." In some implementations, candidate cells may include cells in a neighboring cell list. In other implementations, candidate cells may also include cells detected during the reselection process. Of course, in the embodiments of the present application, candidate cells may also include intra-frequency cells, inter-frequency cells, and cells on frequencies of different RATs, etc.

[0052] Generally, cell reselection can be categorized as intra-frequency cell reselection and inter-frequency cell reselection. Intra-frequency cell reselection can address wireless coverage issues, while inter-frequency cell reselection can be used for both wireless coverage issues and load balancing. The following describes intra-frequency cell reselection and inter-frequency cell reselection, respectively.

[0053] For intra-frequency cell reselection, intra-frequency cell reselection may include the following three steps.

[0054] Step 1: Determine whether to start the same-frequency measurement by comparing the parameters of the serving cell with the parameters broadcast by the system.

[0055] In some implementations, the serving cell parameter may include a cell selection reception value S rxlev , cell selection quality value S qual Among them, S rxlev With S qual The determination method can refer to the S criterion.

[0056] In some implementations, the parameters in the system broadcast include S intrasearchP and S intrasearchQ .

[0057] If S rxlev >S intrasearchP And S qual >S intrasearchQ , the terminal device can choose not to perform the same-frequency measurement; otherwise, the terminal device needs to perform the same-frequency measurement.

[0058] Step 2: Sort the candidate cells by quality using the R criterion and select the best cell.

[0059] In some implementations, the R criterion can be expressed as: s =Q meas,s +Q hyst –Qoffset temp ; and R n =Q meas,n -Qoffset–Qoffset temp Among them, R s Indicates the R value of the serving cell; R n Indicates the R value of the neighboring cell; Q hyst represents the lag value of the sorting criterion; Q meas RSRP value used for cell reselection; Qoffset represents the offset value; Qoffset temp Indicates a temporary offset value.

[0060] It should be noted that for intra-frequency reselection, when a valid inter-cell Qoffset,n is broadcasted in the system, Qoffset is equal to inter-cell Qoffset,n. If no valid inter-cell Qoffset,n is broadcasted in the system, Qoffset is equal to 0. For inter-frequency reselection, when a valid inter-cell Qoffset,n is broadcasted in the system, Qoffset is equal to the sum of inter-frequency Qoffsetfrequency and inter-cell Qoffset,n. If no valid inter-cell Qoffset,n is broadcasted in the system, Qoffset is equal to inter-frequency Qoffsetfrequency.

[0061] In addition, in the above R criterion, the "subscript s" represents the parameter corresponding to the serving cell, and the "subscript n" represents the parameter corresponding to the neighboring cell.

[0062] In some scenarios, the communication system (e.g., NR system) may support multi-beam operation. When performing cell reselection in multi-beam operation, in order to determine the best cell, the network device may configure an equivalent range (expressed as "rangToBestCell") through a system message. Accordingly, if the network device does not configure this parameter, the terminal device may reselect to the cell with the highest R ranking. Conversely, the terminal device will reselect to the cell with the highest R ranking. best -rangToBestCell,R best ] range and the number of cells with the largest number of beam qualities above the threshold (expressed by "absThreshSS-Consolidation"), among which R best Indicates the cell with the highest R value among the measured cells. If multiple cells meet this condition, the terminal device will reselect to the cell with the highest ranking. The reselected cell is considered to be the cell with the highest ranking.

[0063] In scenarios that support multi-beam operation, the terminal device needs to measure the beam. For example, the measurement of the corresponding beam can be completed by measuring the synchronization signal and physical broadcast channel block (SSB) or the channel state information-reference signal (CSI-RS). The measurement process is an energy-consuming process for the terminal device. In order to reduce the power consumption of the terminal device, the SSB-based measurement timing configuration is introduced, also known as the measurement timing configuration (SMTC). SMTC defines the duration and period that can be used to limit the terminal device's measurement of specific resources. That is to say, during the SMTC period, the terminal device can perform wireless resource management measurements on the configured SSB or CSI-RS.

[0064] It should be noted that SMTC can be configured with frequency band as the granularity. SMTC can be applied to the scenarios of intra-frequency cell reselection and / or inter-frequency cell reselection.

[0065] In some implementations, the following constraints may be met during cell ranking and reselection:

[0066] Constraint 1: The signal quality of the selected cell (e.g., new cell) must be better than that of the current cell in the ranking and last for a period of time. For example, the duration is greater than T reseleectionNR .

[0067] Constraint 2: If the terminal device is in a non-normal mobile state, it is necessary to consider the parameter T reseleectionNR With Q hyst to zoom in or out.

[0068] Constraint 3: The terminal device stays in the source cell for more than 1 second.

[0069] Step 3: Determine whether the optimal cell is a suitable cell according to the suitable cell criteria.

[0070] During inter-frequency cell reselection, network devices can achieve load balancing across different frequencies by setting reasonable priority parameters. Inter-frequency cell reselection mainly includes the following three operations.

[0071] Operation 1, measurement.

[0072] For other frequencies whose priority is higher than the current frequency indicated by the system information, the terminal device needs to perform measurements on them. For other frequencies whose priority is equal to or lower than the current frequency indicated by the system information, the terminal device performs the following measurement criteria:

[0073] If the serving cell's S rxlev >S intraSearchP And S qual >S intraSearchQ , the terminal device can choose not to perform the same-frequency measurement; on the contrary, the terminal device needs to start the same-frequency measurement.

[0074] If the serving cell's S rxlev >S nonintraSearchP And S qual >S nonintraSearchQ , the terminal device may choose not to perform inter-frequency measurement or inter-RAT measurement; on the contrary, the terminal device needs to start inter-frequency measurement or inter-RAT measurement.

[0075] Operation 2: Priority processing.

[0076] The terminal device can obtain the frequency priority information (e.g., public priority) through the broadcast message of the network device (e.g., system information), or obtain the frequency priority information (e.g., dedicated priority) through dedicated signaling (e.g., RRC release message), or inherit it from other RATs when performing inter-RAT cell (re)selection.

[0077] In some implementations, if a dedicated priority is provided, the terminal device may ignore all public priorities. If the system information does not provide the priority information of the cell where the terminal device is currently camped, the terminal device may set the priority of the frequency point where the cell is located to the lowest.

[0078] In some implementations, the terminal device may perform cell reselection according to a priority strategy only among the frequencies that appear in the system information and have priority (try to select frequencies with higher priority).

[0079] Operation 3, cell reselection criteria.

[0080] The cell reselection criteria can be divided into the following three categories according to the frequency priority: cell reselection for high-priority frequencies, cell reselection for frequencies of equal priority, and cell reselection for low-priority frequencies. These three situations are described below.

[0081] Case 1: Reselection of a cell with a high priority frequency.

[0082] The terminal device has resided in the current cell for more than 1s. Cell reselection to a cell on a high-priority frequency can meet the signal quality of the cell above the threshold and last for more than the specified time. At this time, the terminal device can reselect the cell.

[0083] Case 2: Reselection of cells with the same priority frequency.

[0084] For cell reselection at frequencies with the same priority, the terminal device can perform R sorting on the cells at frequencies with the same priority based on the R criteria described above, and then select the appropriate cell to camp on. For details, please refer to the above description.

[0085] Case 3: Reselection of a cell with a low priority frequency.

[0086] In some implementations, after a terminal device resides in the current cell for more than 1 second, if no cell on a high-priority frequency or an equal-priority frequency meets the requirements, and the signal quality of the current cell is lower than a threshold, if the signal quality of a cell on a low-priority frequency is higher than the threshold and lasts for a certain period of time, the terminal device can reselect the cell.

[0087] It should be noted that in the cell reselection process described above, the embodiments of the present application do not limit the calculation method of the cell signal quality. In some implementations, if the system message broadcasts the parameter N and the threshold, the cell signal quality can be determined based on the signal quality corresponding to the N best beams that meet the threshold. For example, it can be the linear average of the signal qualities corresponding to the N best beams. In other implementations, if the system message does not broadcast the parameter N and the threshold, the cell signal quality can also be the best signal quality corresponding to the beam in the cell, where N is a positive integer.

[0088] Wake-up receiver (WUR)

[0089] In order to meet the energy-saving needs of terminal devices, the R18 standard plans to introduce WUR (also known as ultra-low power WUR "ultra-low power WUR, LP-WUR") to receive energy-saving signals (also known as "wake-up signal (WUS)", "ultra-low power wake-up signal (ultra-low power WUS, LP-WUS)", low-power wake-up signal, etc.). WUR has the characteristics of extremely low cost, extremely low complexity and extremely low power consumption, and it mainly receives energy-saving signals based on envelope detection. Therefore, the energy-saving signal received by WUR is different from the modulation method, waveform, etc. of the signal based on PDCCH carried by the existing R16 and R17 standards. The energy-saving signal is mainly an envelope signal that ASK modulates the carrier signal. In some implementations, the demodulation of the envelope signal can be completed based on the energy provided by the wireless radio frequency signal to drive the low-power circuit, and the terminal device does not need to be powered, so the WUR can be passive. In other implementations, WUR can also be powered by the terminal device. Regardless of the power supply method, WUR greatly reduces power consumption compared to traditional receivers of terminal devices. For example, WUR can achieve power consumption of less than 1 milliwatt (mW), which is much lower than the power consumption of tens to hundreds of mW of traditional receivers.

[0090] Currently, the WUR can be combined with a terminal device as an additional module of the terminal device's receiver. Of course, the WUR can also be used as a module of a terminal device alone, for example, to implement a wake-up function.

[0091] Figure 2 is a schematic diagram of a terminal device carrying a WUR. Referring to Figure 2, the terminal device 200 may include a main receiver 210 and a WUR220. In order to save power consumption of the terminal device 200, the terminal device 200 may be configured to be in a sleep state (for example, when the terminal device is in a DRX sleep period), or in other words, the main receiver 210 of the terminal device may be in a sleep state (see Figure 2(a)). At this time, the terminal device 200 may utilize the WUR 220 to receive energy-saving signals. In some cases, if the terminal device 200 needs to wake up the main receiver 210, the network device may send a wake-up signal, and accordingly, the terminal device may monitor the WUS through the WUR220. When the WUR220 monitors the WUS, it may wake up the main receiver 210 (see Figure 2(b)). Otherwise, the main receiver 210 of the terminal device may be in a sleep state.

[0092] In some implementations, the WUR monitoring the WUS may include: the WUR monitoring one WUS, or the WUR monitoring multiple WUSs.

[0093] In other implementations, the above-mentioned WUR waking up the main receiver may include: the WUR sending a WUS to the main receiver, the WUS is used to wake up the main receiver, or the WUR sending a wake-up indication information to the main receiver, the wake-up indication information is used to wake up the main receiver.

[0094] To facilitate differentiation, the following describes the differences between the WUR and the main receiver in terms of modulation method, modulation waveform, transmission rate, supported bandwidth range, bit rate, etc.

[0095] From the perspective of the modulation methods supported by the two, the complexity of the modulation method supported by WUR is lower than the complexity of the modulation method supported by the main receiver. In some implementations, the modulation methods supported by WUR may include one or more of the following modulation methods: amplitude shift keying (ASK), phase shift keying (PSK), frequency shift keying (FSK), etc. Correspondingly, the modulation methods supported by the main receiver may include one or more of the following modulation methods: quadrature phase shift keying (QPSK), quadrature amplitude modulation (QAM), orthogonal frequency division multiplexing (OFDM), etc. Of course, in other implementations, the main receiver may also support at least one of the modulation methods of ASK, PSK, and FSK. The embodiments of the present application do not specifically limit this.

[0096] Judging from the modulation waveforms supported by the two, the complexity of the modulation waveform supported by WUR is lower than the complexity of the modulation waveform supported by the main receiver, or in other words, the modulation waveform supported by WUR is simpler than the modulation waveform supported by the main receiver. For example, the modulation waveform supported by WUR may include one or more of the following modulation waveforms: the waveform corresponding to the ASK signal, the waveform corresponding to the PSK signal, and the waveform corresponding to the FSK signal. Correspondingly, the modulation waveform supported by the main receiver may include one or more of the following modulation waveforms: the waveform corresponding to the QPSK signal, the waveform corresponding to the QAM signal, and the waveform corresponding to the OFDM signal. Of course, in some embodiments, the modulation waveform supported by the main receiver may also include waveforms corresponding to one or more signals of ASK, PSK, and FSK.

[0097] Judging from the transmission rates supported by the two, the transmission rate supported by WUR is lower than the transmission rate supported by the main receiver. For example, the transmission rate supported by WUR is less than the first rate threshold, and the value of the first rate threshold can be in the range of 1Kbps to 1Mbps, wherein the value of the first rate threshold can be 1Kbps, 128Kbps, 515Kbps or 1Mbps, etc. Correspondingly, the transmission rate supported by the main receiver can be greater than the first rate threshold. For example, the transmission rate supported by the main receiver can be greater than 10Kbps, 100Kbps, 1000Kbps, 1Gbps, etc.

[0098] From the perspective of the bandwidth ranges supported by the two, the bandwidth range supported by the WUR is smaller than the bandwidth range supported by the primary receiver, or in other words, the bandwidth supported by the WUR is narrower than the bandwidth supported by the primary receiver. For example, the bandwidth supported by the WUR can be less than or equal to the first bandwidth threshold, and the value of the first bandwidth threshold can be in the range of 1KB to 1MB, wherein the value of the first bandwidth threshold can be 1KB, 128KB, 515KB or 1MB, etc. Correspondingly, the bandwidth supported by the primary receiver can be greater than the first bandwidth threshold, for example, the bandwidth supported by the primary receiver can be greater than 10KB, 100KB, 1000KB, 1GB, etc.

[0099] Judging from the bitrates supported by both, the bitrate supported by the WUR is lower than the bitrate supported by the primary receiver. For example, the bitrate supported by the WUR is less than or equal to the first bitrate threshold, which can be between 0.3 and 0.6. For example, the first bitrate threshold can be 0.3, 0.5, or 0.6. Correspondingly, the bitrate supported by the primary receiver can be greater than the first bitrate threshold. For example, the bitrate supported by the primary receiver can be greater than 0.7, 0.8, 0.9, or close to 1.

[0100] As mentioned above, to reduce power consumption in terminal devices, WUR is introduced to receive LP-WUS, allowing the terminal device to turn off its primary receiver. However, according to existing cell selection or reselection strategies, after cell selection or reselection, the cell where the terminal device resides may not support LP-WUS. In this case, the terminal device cannot use WUR in the cell it is residing in and turns off its primary receiver, resulting in continued high power consumption.

[0101] Therefore, an embodiment of the present application provides a wireless communication method in which a terminal device can receive first information associated with an LP-WUS, which is used to select a camping cell during cell selection or cell reselection. This helps increase the likelihood that the terminal device will camp on a cell that supports LP-WUS, thereby reducing power consumption of the terminal device. The wireless communication method of an embodiment of the present application is described below with reference to FIG3 .

[0102] FIG3 is a flow chart of a wireless communication method according to an embodiment of the present application. The method shown in FIG3 includes step S310.

[0103] In step S310, the network device sends first information to the terminal device.

[0104] In some implementations, the first information is used for cell reselection or cell selection. In other words, the terminal device may perform cell selection or cell reselection based on the first information.

[0105] In some implementations, the first information may be associated with LP-WUS, or in other words, the first information may be related to LP-WUS. For example, the first information may be used to indicate whether LP-WUS is supported, where whether LP-WUS is supported may include, for example, whether LP-WUS sending is supported. Alternatively, the first information may be associated with LP-WUS functionality. For example, the first information may be used to indicate whether LP-WUS functionality is supported, where whether LP-WUS sending is supported may include, for example, whether LP-WUS support is supported.

[0106] In some implementations, the first information may be carried in a system message, for example, in SIB1. For another example, the first information may be carried in SIB3, or in SIB4. Of course, in the embodiments of the present application, the first information may also be dedicated information. This embodiment of the present application is not limited thereto.

[0107] In some implementations, the terminal device may be a terminal device that supports LP-WUS, for example, the terminal device shown in Figure 2. Of course, in the embodiment of the present application, the terminal device may also be a terminal device that does not support LP-WUS, and the embodiment of the present application is not limited to this.

[0108] As described above, for a terminal device in an idle state or an inactive state, a suitable cell can be selected for camping through cell selection and / or cell reselection. Therefore, in the embodiment of the present application, the terminal device may be a terminal device in an idle state or an inactive state.

[0109] In the embodiment of the present application, the object to which the first information is directed is not limited. In some implementations, the first information may include information for a cell, or the first information may include cell-level information, or the first information may include information corresponding to a cell (e.g., a first cell). The cell may include a co-frequency cell and / or an inter-frequency cell. The co-frequency cell may be understood as a co-frequency cell of the serving cell. The inter-frequency cell may be understood as an inter-frequency cell of the serving cell.

[0110] In other implementations, the first information may include information about a frequency, or in other words, the first information may include frequency-level information, or in other words, the first information may include information corresponding to a frequency (e.g., a first frequency), where the frequency may include a co-frequency frequency and / or an inter-frequency frequency. The co-frequency frequency may be understood as a co-frequency frequency of the serving cell. The inter-frequency frequency may be understood as a inter-frequency frequency of the serving cell.

[0111] The following description will be made by taking the example that the first information includes cell-level information or frequency-level information.

[0112] The first information includes cell-level information

[0113] In some implementations, the information corresponding to the first cell may be used to indicate whether the first cell supports LP-WUS, or the information corresponding to the first cell may be used to indicate whether the first cell supports LP-WUS functionality.

[0114] In an embodiment of the present application, the information corresponding to the first cell is introduced during the cell selection or cell reselection process, which helps the terminal device select a cell that supports LP-WUS as the target cell based on the information corresponding to the first cell. In this way, the terminal device can receive the paging signal in the target cell with a low-power receiver to reduce the power consumption of the terminal device.

[0115] In some implementations, the information corresponding to the first cell can be presented in the form of a list. In some implementations, if the first cell is a cell that supports LP-WUS, the first cell can be included in the list. That is to say, the cells included in the list are cells that support LP-WUS. Therefore, the list can also be called a "white list". As described above, the first cell can be an intra-frequency cell, or in other words, the cells in the list are intra-frequency cells. Accordingly, the white list can also be called an "intra-frequency cell white list list", which can be represented by "intraFreqWhiteCellListLP-WUS". Of course, the first cell can also be an inter-frequency cell, or in other words, the cells in the list are inter-frequency cells. Accordingly, the white list can also be called an "inter-frequency cell white list list", which can be represented by "inerFreqWhiteCellListLP-WUS".

[0116] In other implementations, if the first cell is a cell that does not support LP-WUS, then the first cell may be included in the list, that is, the cells in the list are cells that do not support LP-WUS. Therefore, the list can also be called a "black list". As described above, the first cell can be an intra-frequency cell, or in other words, the cells in the list are intra-frequency cells. Accordingly, the blacklist can also be called an "intra-frequency cell blacklist list", which can be represented by "intraFreqBlackCellListLP-WUS". Of course, the first cell can also be an inter-frequency cell, or in other words, the cells in the list are inter-frequency cells. Accordingly, the blacklist can also be called an "inter-frequency cell blacklist list", which can be represented by "inerFreqBlackCellListLP-WUS".

[0117] Typically, the SIB3 of the system message can be used for intra-frequency cell reselection and may include intra-frequency cell (e.g., intra-frequency neighbor cell) information. Therefore, in an embodiment of the present application, information corresponding to the intra-frequency cell (e.g., intra-frequency cell whitelist and / or intra-frequency cell blacklist) may be carried in the SIB3.

[0118] The following takes the same-frequency cell whitelist list and the same-frequency cell blacklist list as examples to illustrate the SIB3 implementation method in the embodiment of the present application. Referring to the SIB3 code shown below, it can be seen that the parameters that can be carried in SIB3 include one or more of the following: same-frequency neighbor list (expressed by "intraFreqNeighCellList" and "intraFreqNeighCellList-v1610"); same-frequency blacklist neighbor list (expressed by "intraFreqBlackCellList"); delayed non-critical extension (expressed by "lateNonCriticalExtension"); same-frequency whitelist neighbor list (expressed by "intraFreqWhiteCellList-r16"); same-frequency adjacent CAG cell list (expressed by "intraFreqCAG-CellList-r16"); same-frequency cell blacklist list (intraFreqBlackCellListLP-WUS) and same-frequency cell whitelist list (intraFreqWhiteCellListLP-WUS). That is to say, the intra-frequency cell blacklist (intraFreqBlackCellListLP-WUS) and the intra-frequency cell whitelist (intraFreqWhiteCellListLP-WUS) may be carried in SIB3.

[0119]

[0120]

[0121] It should be noted that there are many ways to implement the information corresponding to the cell in SIB3, for example, directly adding a whitelist and / or a blacklist in SIB3 as described above. Of course, since SIB3 carries information about the same-frequency cell, in the embodiment of the present application, the information corresponding to the cell can also be directly added to the information about the same-frequency cell already included in SIB3 to indicate whether the cell supports LP-WUS.

[0122] In addition, SIB3 in the embodiment of the present application may also carry other parameters in addition to the above parameters, which is not limited in the embodiment of the present application.

[0123] Typically, SIB4 of the system message can be used for inter-frequency cell reselection and may include information about inter-frequency cells (e.g., inter-frequency neighboring cells). Therefore, in an embodiment of the present application, information about the corresponding inter-frequency cells (e.g., an inter-frequency cell whitelist and / or an inter-frequency cell blacklist) may be carried in SIB4.

[0124] The following takes the inter-frequency cell whitelist list and the inter-frequency cell blacklist list as examples to illustrate the implementation method of SIB4 in the embodiment of the present application. Referring to the SIB4 code shown below, it can be seen that the parameters that can be carried in SIB4 include one or more of the following: inter-frequency carrier frequency list (expressed by "interFreqCarrierFreqList" and "interFreqCarrierFreqList-v1610"); delayed non-critical extension (expressed by "lateNonCriticalExtension"). Inter-frequency carrier frequency information (expressed by "InterFreqCarrierFreqInfo"). Cell reselection priority (expressed as "cellReselectionPriority"); SUL cell reselection priority (expressed as "cellReselectionSubPriority"); cell reselection offset-Q (expressed as "q-OffsetFreq"); inter-frequency neighbor cell list (expressed as "interFreqNeighCellList"); inter-frequency blacklist neighbor cell list (expressed as "interFreqBlackCellList"); inter-frequency cell blacklist list (interFreqBlackCellListLP-WUS), and inter-frequency cell whitelist list (interFreqWhiteCellListLP-WUS)

[0125] The above-mentioned inter-frequency carrier frequency information may include one or more of the following: downlink carrier frequency (expressed by "dl-CarrierFreq"); frequency band list (expressed by "frequencyBandList"); supplementary uplink (SUL) frequency band list (expressed by "frequencyBandListSUL"); number of SSBs (expressed by "nrofSS-BlocksToAverage"); threshold (expressed by "absThreshSS-BlocksConsolidation"); SMTC configuration (expressed by "smtc"); SSB subcarrier spacing (expressed by "ssbSubcarrierSpacing"); SSB measurement (expressed by "ssb-ToMeasure"); parameter used to indicate the SSB index calculation method (expressed by "deriveSSB-IndexFromCell"); received signal strength indication of SS (received signal strength The following items are used for the measurement of the following signals: Signal Indicator (RSSI) measurement (expressed as "ss-RSSI-Measurement"); minimum cell access level (expressed as "q-RxLevMin"); minimum SUL cell access level (expressed as "q-RxLevMinSUL"); minimum cell access quality (expressed as "q-QualMin"); maximum terminal transmit power (expressed as "p-Max"); cell reselection time delay (expressed as "t-ReselectionNR"); cell reselection speed factor (expressed as "threshX-LowP"); cell reselection-signal quality threshold (expressed as "threshX-Q"); low priority reselection threshold (expressed as "t-ReselectionNR-SF"); cell reselection speed factor (expressed as "t-ReselectionNR-SF").

[0126] That is to say, in the embodiment of the present application, the inter-frequency cell blacklist (interFreqBlackCellListLP-WUS) and the inter-frequency cell whitelist (interFreqWhiteCellListLP-WUS) can be directly added to SIB4.

[0127]

[0128]

[0129]

[0130] An embodiment of the present application also provides an implementation method of SIB4. It should be noted that the parameters contained in SIB4 are similar to the parameters contained in SIB4 introduced above. For the sake of brevity, the following mainly introduces the carrying method of the inter-frequency cell blacklist and the inter-frequency cell whitelist.

[0131] As can be seen from the SIB4 code shown below, SIB4 includes an inter-frequency carrier frequency list (represented by "interFreqCarrierFreqList-v17xy"). Accordingly, the inter-frequency carrier frequency list can carry an inter-frequency cell blacklist list (interFreqBlackCellListLP-WUS) and an inter-frequency cell whitelist list (interFreqWhiteCellListLP-WUS). That is to say, in an embodiment of the present application, a new parameter can be added to SIB4 to carry an inter-frequency cell blacklist list (interFreqBlackCellListLP-WUS) and an inter-frequency cell whitelist list (interFreqWhiteCellListLP-WUS).

[0132]

[0133] It should be noted that in the embodiment of the present application, SIB4 can also carry other parameters in addition to the above parameters, and the embodiment of the present application does not limit this.

[0134] The above introduces the information corresponding to the first cell in the embodiment of the present application, and the following introduces the usage of the information corresponding to the first cell in the embodiment of the present application.

[0135] In some implementations, if the first cell does not support the low-power wake-up signal, the first cell does not belong to the candidate cell in cell selection / cell reselection, or in other words, the terminal device does not consider the first cell as a candidate cell.

[0136] The fact that the first cell is not a candidate cell can be understood as excluding the first cell during cell reselection or cell selection, or in other words, the terminal device does not measure the first cell. Of course, in the embodiment of the present application, the terminal device may also measure the first cell, but does not select the first cell as a candidate cell.

[0137] Of course, in an embodiment of the present application, if the first cell does not support low-power wake-up signals, the first cell may also be a candidate cell. However, the priority of the first cell may be lower than other cells in the candidate cells that support low-power wake-up signals to increase the probability that the terminal device selects other cells that support low-power wake-up signals.

[0138] In other implementations, if the first cell supports low power wake-up signals, the first cell belongs to the candidate cells in cell selection / cell reselection, and the priority of the first cell is higher than other cells in the candidate cells that do not support low power wake-up signals.

[0139] The above-mentioned first cell belonging to a candidate cell can be understood as taking the first cell as a candidate cell during the cell reselection or cell selection process, or in other words, the terminal device measures the first cell.

[0140] In some implementations, in order to increase the probability that the terminal device selects a cell that supports LP-WUS as the target cell after the cell selection or cell reselection process, the terminal device may give priority to selecting a cell that supports LP-WUS as the target cell during the cell selection or cell reselection process.

[0141] For example, in the cell reselection process described above, the terminal device can sort the candidate cells according to the R criterion. Accordingly, when selecting the target cell, the terminal device can select the cell with the highest sorting position (for example, the corresponding R is the largest) and supporting LP-WUS as the target cell.

[0142] For example, in the cell reselection process introduced above, the terminal device can sort the cells in the whitelist according to the R criterion. Accordingly, when selecting the target cell, the terminal device can use the cell with the highest ranking position in the whitelist (for example, the corresponding R is the largest) as the target cell.

[0143] The first information includes frequency level information

[0144] In some implementations, the information corresponding to the first frequency may be used to indicate whether the first frequency supports LP-WUS, or the information corresponding to the first frequency may be used to indicate whether the first frequency supports LP-WUS functionality.

[0145] In an embodiment of the present application, whether the first frequency supports LP-WUS is indicated by information corresponding to the first frequency. That is, whether LP-WUS is supported is indicated at the frequency granularity. Compared with the solution of indicating whether LP-WUS is supported at the cell granularity, this helps to reduce the transmission overhead of the first information.

[0146] In some implementations, the communication protocol specifies that SIB3 can be used to carry information about intra-frequency cells. Therefore, to minimize changes to the communication protocol, if the first frequency is an intra-frequency cell, the information corresponding to the first frequency can be carried in SIB3. For example, a new parameter can be added to SIB3 to carry information corresponding to the first frequency.

[0147] In other implementations, the communication protocol stipulates that SIB4 can be used to carry information of inter-frequency cells. Therefore, in order to reduce changes to the communication protocol, if the first frequency point is an inter-frequency point, the information corresponding to the first frequency point can be carried in SIB4.

[0148] For example, referring to the code corresponding to SIB4 above, the information corresponding to each inter-frequency point can be carried in the inter-frequency point list (represented by "interFreqCarrierFreqList") to indicate whether the inter-frequency point supports LP-WUS. Of course, in the embodiment of the present application, dedicated information can also be directly added to SIB4 to indicate the information corresponding to the inter-frequency point. The embodiment of the present application does not specifically limit the manner in which the information corresponding to the first frequency point is carried in SIB4.

[0149] The above describes the information corresponding to the first frequency point in the embodiment of the present application. The following describes how to use the information corresponding to the first frequency point in the embodiment of the present application. In the embodiment of the present application, the information corresponding to the first frequency point can affect the cell reselection or cell selection process at the granularity of the cell in the first frequency point, or it can affect the cell reselection or cell selection process at the granularity of the frequency point. The following describes the above two situations respectively.

[0150] In some implementations, if the first frequency does not support the low-power wake-up signal, the first frequency does not belong to the candidate cell in cell selection / cell reselection, or in other words, the terminal device does not consider the cell in the first frequency as a candidate cell.

[0151] The fact that the cell in the first frequency band is not a candidate cell can be understood as excluding the first frequency band during the cell reselection or cell selection process, or in other words, the terminal device does not measure the cell in the first frequency band. Of course, in the embodiment of the present application, the terminal device may also measure the cell in the first frequency band, but does not select the cell in the first frequency band as a candidate cell.

[0152] Of course, in an embodiment of the present application, if the first frequency point does not support low-power wake-up signals, the cells in the first frequency point may also be candidate cells. However, the priority of the cells in the first frequency point may be lower than other cells in the candidate cells that support low-power wake-up signals, so as to increase the probability that the terminal device selects other cells that support low-power wake-up signals.

[0153] In other implementations, if the first frequency point supports low-power wake-up signals, the cells in the first frequency point belong to candidate cells in cell selection / cell reselection, and the priority of the cells in the first frequency point is higher than other cells in the candidate cells that do not support low-power wake-up signals.

[0154] The cell in the first frequency point mentioned above being a candidate cell can be understood as taking the cell in the first frequency point as a candidate cell during cell reselection or cell selection, or in other words, the terminal device measures the cell in the first frequency point.

[0155] The above describes how the information corresponding to the first frequency point affects the cell reselection or cell selection process at the granularity of the cell in the first frequency point. The following describes how the information corresponding to the first frequency point affects the cell reselection or cell selection process at the granularity of the frequency point.

[0156] In some scenarios, such as the cell reselection process described above, the network device can indicate the priority corresponding to the frequency (i.e., the "cell reselection priority" mentioned above) to the terminal device through a system message, so that the terminal device can select an appropriate frequency based on the cell reselection priority. Therefore, in order to increase the probability of the terminal device selecting a frequency that supports LP-WUS, the cell reselection priority can be determined based on the first information.

[0157] In some implementations, if the first information is used to indicate that the first frequency supports the low power wake-up signal, the cell reselection priority corresponding to the first frequency is the highest priority.

[0158] In an embodiment of the present application, setting the cell reselection priority corresponding to the first frequency point to the highest priority helps to increase the probability of the terminal device staying at the first frequency point, thereby increasing the opportunity to use the LP-WUS signal and helping to reduce the power consumption of the terminal device.

[0159] In some other implementations, if the first information is used to indicate that the first frequency does not support the low power wake-up signal, the cell reselection priority corresponding to the first frequency is the lowest priority.

[0160] In an embodiment of the present application, the cell reselection priority corresponding to the first frequency point is set to the lowest priority, which helps to reduce the time for the terminal to measure or discover the cell supporting LP-WUS, and increases the chance of the terminal device reselecting to the cell supporting LP-WUS, thereby reducing the power consumption of the terminal device.

[0161] In some implementations, the cell reselection priority may be determined by the terminal device. That is, the cell reselection priority corresponding to the first frequency may be determined by the terminal device. For example, after the network device configures the reselection priority corresponding to the first frequency, the terminal device may adjust the cell reselection priority for the first frequency based on the cell reselection priority configured by the network device and according to the first information, where the adjustment includes increasing and / or decreasing the priority.

[0162] For example, if the first information indicates that the first frequency point supports the LP-WUS point, the terminal device can configure the cell reselection priority of the first frequency point to the highest priority. For example, if the frequency point where the serving cell is located (i.e., the first frequency point) supports LP-WUS, the terminal device can adjust the cell reselection priority corresponding to the frequency point where the serving cell is located to the highest priority.

[0163] For another example, if the first information indicates that the first frequency does not support LP-WUS, the terminal device may configure the cell reselection priority of the first frequency to be the lowest priority. For example, if the frequency of the serving cell (i.e., the first frequency) does not support LP-WUS, the terminal device may adjust the cell reselection priority corresponding to the frequency of the serving cell to the lowest priority.

[0164] Of course, in an embodiment of the present application, the cell reselection priority can be determined by the network device, that is, the cell reselection priority corresponding to the first frequency point can be determined by the network device, and then the network device indicates the determined cell reselection priority to the terminal device. For example, if the first information indicates that the first frequency point supports LP-WUS, the network device can adjust the cell reselection priority corresponding to the first frequency point to the highest priority, and then the network device can indicate to the terminal device that the cell reselection priority corresponding to the first frequency point is the highest priority. For another example, if the first information indicates that the first frequency point does not support LP-WUS, the network device can adjust the cell reselection priority corresponding to the first frequency point to the lowest priority, and then the network device can indicate to the terminal device that the cell reselection priority corresponding to the first frequency point is the lowest priority.

[0165] It should be noted that the above description uses cell-level information and frequency-level first information as examples. In an embodiment of the present application, the cell-level information and the frequency-level first information can be used separately or in combination. For example, the first information can indicate that when the first frequency supports LP-WUS, it indicates which cell in the first frequency supports LP-WUS. For another example, the first information can indicate that when the first frequency does not support LP-WUS, it indicates which cell in the first frequency does not support LP-WUS. For another example, the first information can indicate that when the first frequency supports LP-WUS, it indicates which cell in the first frequency does not support LP-WUS. For another example, the first information can indicate that when the first frequency does not support LP-WUS, it indicates which cell in the first frequency does not support LP-WUS. For another example, the first information can indicate that when the first frequency does not support LP-WUS, it indicates which cell in the first frequency supports LP-WUS.

The device embodiment of the present application is described in detail below in conjunction with Figures 4 to 6 . It should be understood that the description of the method embodiment corresponds to the description of the device embodiment. Therefore, for parts not described in detail, reference can be made to the above method embodiment.
