[0106] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Futuregeneration radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0107] To further reduce UE power consumption, a mechanism based on LP-WUR is being discussed in 3GPP Release 18 / R19 for 5G systems. In power-saving mode, the UE can put its main receiver into ultra-deep sleep and enable LP-WUR to listen for low-power wake-up signals (LP-WUS). When the UE detects an LP-WUS signal for itself via LP-WUR, it turns on its main receiver and performs normal transmission. This mechanism significantly reduces the power consumption of the main receiver, and since LP-WUR has very low power consumption, it further increases the UE's power-saving gains.

[0108] In some embodiments, the LP-WUR can support at least two types. One type of LP-WUR only supports envelope detection of on-off keying (OOK) symbols of the LP-WUS. An LP-WUR supporting envelope detection of OOK symbols can be called an OOK LR. The link performance of an OOK LR is relatively poor. Another type of LP-WUR can detect the time-domain or frequency-domain sequence of orthogonal frequency division multiplexing (OFDM) carried by the OOK symbols of the LP-WUS, thereby improving link performance. An LP-WUS supporting OFDM can be called an OFDM LR. In some embodiments, the OFDM LR can detect the primary synchronization signal (PSS) sequence / secondary synchronization signal (SSS) sequence in existing protocols. However, if the PSS / SSS is not in the frequency band supported by the OFDM LR, the OFDM LR cannot receive the PSS / SSS.

[0109] In some embodiments, for proper LP-WUS detection, the UE needs to obtain the time and frequency location of the base station transmitting the LP-WUS. The UE can obtain and maintain time and frequency synchronization by detecting synchronization signals. For example, when the main receiver is on, the UE obtains synchronization by detecting a synchronization signal block (SSB). For example, after the main receiver is off and the LP-WUS is on, the UE maintains synchronization using a low-power synchronization signal (LP-SS) specifically for LP-WUS (for LP-WUS that can perform OFDM signal detection, synchronization can also continue to be maintained via the SSB). In addition to being used for synchronization, the LP-SS can also serve as a reference signal for radio resource management (RRM) measurements.

[0110] In some embodiments, the base station can broadcast the frequency domain locations of the cell's LP-WUS and LP-SS to the terminal via system information. A UE in RRC idle state can obtain the configuration information (including frequency domain location, time domain location, power information, etc.) of its cell's LP-WUS / LP-SS by listening to system information. Thus, when the UE determines that it is entering a primary transceiver sleep state, the UE can use LP-WUS to listen to LP-SS / LP-WUS at the configured frequency / time domain locations.

[0111] In some embodiments, not all frequencies support LP-WUR in operator deployments. For example, only some carrier frequencies or frequency bands support LP-WUR in network deployments. However, operators want all LP-WUR-enabled UEs to prioritize camping on LP-WUR-enabled frequency bands, which can lead to excessive congestion on those bands. In one approach, LP-WUR-enabled UEs are initially prioritized for camping on LP-WUR-enabled frequency bands. Then, when a service needs to be initiated, the UE will perform a cell reselection to initiate the service as quickly as possible.

[0112] Therefore, determining whether a terminal is performing cell reselection is a technical problem that urgently needs to be solved.

[0113] Figure 2 This is an interactive schematic diagram of a communication method provided according to an embodiment of this disclosure. The communication method involved in this embodiment can be applied to a communication system 100. Figure 2 As shown, the communication method of this embodiment includes steps S201 to S206.

[0114] In step S201, network device 102 sends second information to terminal 101.

[0115] In some embodiments, network device 102 may send second information. In some embodiments, the second information may be sent by network device 102, but is not limited thereto, and may also be sent by other entities.

[0116] In some embodiments, terminal 101 may receive second information. In some embodiments, the second information may be received by terminal 101, but is not limited thereto, and may also be received by other entities.

[0117] In some embodiments, the second information may be used by terminal 101 to perform the first operation. In some embodiments, the second information may be used to assist terminal 101 in performing the first operation. In some embodiments, the second information may be used for terminal 101 to consider in order to perform the first operation.

[0118] In some embodiments, the first operation may include at least one of the following: cell selection, cell reselection, and cell redirection. In some embodiments, the second information may be used by terminal 101 to perform cell selection, cell reselection, or cell redirection.

[0119] In some embodiments, the second information can be used to assist the terminal 101 in performing a first operation under specific circumstances. In some embodiments, the specific circumstances may be the triggering of a first event. In some embodiments, the second information can be used to assist the terminal 101 in performing a first operation when the first event is triggered. In some embodiments, the second information can be used to assist the terminal 101 in performing a first operation when the first event is triggered.

[0120] In some embodiments, the name of the second information is not limited, and it may be, for example, auxiliary information, reference information, etc.

[0121] In some embodiments, the first event may include at least one of the following: the terminal 101 is paged by the network; the terminal 101 has uplink data to be sent; the signal quality detected by LP-WUR is lower than a first threshold.

[0122] In some embodiments, the second information may include at least one of the following: cell identifier, cell list, frequency point information, frequency point list, priority information, and frequency point characteristic information.

[0123] In some embodiments, the second information may include a cell identifier. This cell identifier may indicate a cell. In one example, the cell identifier in the second information may be a cell ID. For example, the cell identifier may indicate cell 1.

[0124] In some embodiments, the second information may include a list of cells. This list of cells may indicate at least one cell. In one example, the list of cells may include cell identifiers for at least one cell. For example, the list of cells may include cell 1, cell 2, cell 3, and cell 4.

[0125] In some embodiments, the cell list indicated by the second information may be a whitelist. In this case, the cells in the cell list indicated by the second information can be used as target cells for the terminal 101 to perform the first operation. For example, the cell list may include cell 1, cell 2, cell 3, and cell 4, then cell 1, cell 2, cell 3, and cell 4 can be used as target cells for the terminal 101 to perform the first operation.

[0126] In some embodiments, the cell list indicated by the second information may be a blacklist. In this case, cells in the cell list indicated by the second information cannot be used as target cells for the terminal 101 to perform the first operation. For example, the cell list may include cell 1, cell 2, cell 3, and cell 4, then cell 1, cell 2, cell 3, and cell 4 cannot be used as target cells for the terminal 101 to perform the first operation.

[0127] In some embodiments, the frequency points in the blacklist of cells may be overloaded cells.

[0128] In some embodiments, the second information may include frequency point information. This frequency point information may indicate a frequency point. For example, the frequency point information may indicate frequency point 1. In one example, the frequency point information in the second information may indicate the center frequency and / or bandwidth of the frequency point. In one example, the frequency point information in the second information may indicate the index value of the frequency point.

[0129] In some embodiments, the second information may include frequency point information and priority information. In some embodiments, the priority information may indicate that the frequency point indicated by the frequency point information has the highest priority. For example, the frequency point information may indicate frequency point 1. For example, the priority information may have a first value to indicate that frequency point 1 has the highest priority.

[0130] In some embodiments, the second information may include a frequency point list. This frequency point list may indicate at least one frequency point. For example, the frequency point list may include frequency point 1, frequency point 2, frequency point 3, and frequency point 4. In one example, the frequency point list may indicate the center frequency and / or bandwidth of at least one frequency point. In one example, the frequency point list may include the index value of at least one frequency point.

[0131] In some embodiments, the second information may include a frequency point list and priority information. In some embodiments, each frequency point in the frequency point list may have a priority. The priority of each frequency point may be indicated by priority information. In some embodiments, priority information may indicate the priority among the frequency points in the frequency point list. For example, the frequency point list may include frequency point 1, frequency point 2, frequency point 3, and frequency point 4, and the priority information indicates that frequency point 1 has a first priority, frequency point 2 has a second priority, frequency point 3 has a third priority, and frequency point 4 has a fourth priority. Here, the first priority indicates the highest priority, and the fourth priority indicates the lowest priority. In some embodiments, priority information may indicate the priority and sub-priority among the frequency points in the frequency point list. For example, the frequency point list may include frequency point 1, frequency point 2, frequency point 3, and frequency point 4, and the priority information indicates that frequency point 1 has a first priority, frequency point 2 has a first priority, frequency point 3 has a second priority, and frequency point 4 has a third priority, and also indicates that frequency point 1 has a first sub-priority, and frequency point 2 has a second sub-priority. Here, the first priority indicates the highest priority, and the fourth priority indicates the lowest priority; the first sub-priority is higher than the second sub-priority.

[0132] In some embodiments, at least one frequency point in the frequency point list may only support the main receiver. In some embodiments, each frequency point in the frequency point list may support the main receiver and not support LP-WUR. In this case, the main receiver of terminal 101 can operate on the frequency points in the frequency point list, and the LP-WUR of terminal 101 cannot operate on the frequency points in the frequency point list.

[0133] In some embodiments, the frequency list indicated by the second information may be a whitelist. In this case, the frequency points in the frequency list indicated by the second information may support the terminal 101 in performing the first operation. In some embodiments, the frequency points in the frequency list are used as target frequency points for the terminal 101 to perform the first operation. For example, the frequency list may include frequency point 1, frequency point 2, frequency point 3, and frequency point 4, then frequency point 1, frequency point 2, frequency point 3, and frequency point 4 may be used as target frequency points for the terminal 101 to perform the first operation.

[0134] In some embodiments, the frequency list indicated by the second information may be a blacklist. In this case, the frequencies in the frequency list indicated by the second information may not support the terminal 101 performing the first operation. In some embodiments, the frequencies in the frequency list cannot be used as target frequencies for the terminal 101 to perform the first operation. For example, if the frequency list may include frequency 1, frequency 2, frequency 3, and frequency 4, then frequency 1, frequency 2, frequency 3, and frequency 4 cannot be used as target frequencies for the terminal 101 to perform the first operation.

[0135] In some embodiments, the frequency points in the blacklist of frequency points may be frequency points that are overloaded.

[0136] It should be noted that a frequency point can be understood as a frequency range with a certain bandwidth. A frequency point can also be referred to as a frequency band, frequency range, etc., and this disclosure does not specifically limit it in this way.

[0137] In some embodiments, the second information may further include frequency point characteristic information. In some embodiments, the frequency point characteristic information may be used to indicate that each frequency point in the frequency point list supports LP-WUR and / or the main receiver. In some embodiments, the frequency point characteristic information may be used to determine the support capability of each frequency point for LP-WUR and the main receiver.

[0138] In some embodiments, frequency point characteristic information may indicate whether each frequency point supports a master receiver and / or LP-WUR. In some embodiments, frequency point characteristic information may indicate that a frequency point in the frequency point list supports both a master receiver and LP-WUR. In some embodiments, frequency point characteristic information may indicate that a frequency point in the frequency point list supports a master receiver but does not support LP-WUR. In some implementations, frequency point characteristic information may indicate this for each frequency point in the frequency point list, and different frequency points may have different levels of support for a master receiver and / or LP-WUR. For example, the frequency point list may include frequency point 1, frequency point 2, frequency point 3, and frequency point 4. In one case, frequency point characteristic information may indicate that frequency points 1 and 2 support both a master receiver and LP-WUR, and may indicate that frequency points 3 and 4 support only a master receiver. In one case, frequency point characteristic information may indicate that frequency points 1, 2, 3, and 4 all support both a master receiver and LP-WUR. In one case, frequency point characteristic information may indicate that frequency points 1, 2, 3, and 4 support only a master receiver.

[0139] In some embodiments, frequency point characteristic information can indicate the priority among frequency points with different support capabilities in the frequency point list. In some embodiments, in the frequency point list, the priority of a frequency point that only supports the main receiver can be higher than the priority of a frequency point that supports both the main receiver and LP-WUR. In other words, frequency point characteristic information can indicate that frequency points that only support the main receiver have high priority. For example, the frequency point list may include frequency point 1, frequency point 2, frequency point 3, and frequency point 4. Frequency points 1 and 2 support both the main receiver and LP-WUR, while frequency points 3 and 4 only support the main receiver; therefore, frequency points 3 and 4 can have high priority.

[0140] In some embodiments, the second information may be carried in at least one of the following: a system message or an RRC message.

[0141] In some embodiments, terminal 101 may receive a system message from network device 102, which may contain second information.

[0143] In some embodiments, the system message may further include cell configuration information. In some embodiments, where the second information includes a cell identifier or a cell list, the cell configuration information may include configuration information for one or more cells indicated by the cell identifier or cell list. In some embodiments, the cell configuration information may include random access channel (RACH) configuration. The RACH configuration can be used by terminal 101 to perform random access.

[0144] In some embodiments, terminal 101 may receive an RRC message from network device 102, which may contain second information.

[0145] In some embodiments, the RRC message may be an RRC release message.

[0146] In some embodiments, the second information may be received before the terminal 101 enters a deep sleep state. In some embodiments, when the main receiver of the terminal 101 is working, the terminal 101 can receive the second information from the network device 102 through the main receiver.

[0150] In some embodiments, the first information can be used to indicate a condition for executing the first operation. This condition can be used to determine whether terminal 101 executes the first operation or not. In one example, this condition can be used to further determine whether terminal 101 executes the first operation or not when a first event is triggered.

[0151] In some embodiments, the first information may be used by terminal 101 to determine whether to perform a first operation. In some embodiments, the first information may be used by terminal 101 to determine whether to perform cell selection, cell reselection, or cell redirection. In some embodiments, the first information may be used to instruct terminal 101 to perform the first operation or to keep in the current cell.

[0152] In some embodiments, the first information may indicate at least one of the following: if the first event is triggered, the terminal 101 performs the first operation; if the first event is triggered, the terminal 101 does not perform the first operation.

[0153] In some embodiments, network device 102 may determine that the cell or frequency band currently in which terminal 101 is located is not in a congested state. In this case, network device 102 may send first information to terminal 101 to instruct terminal 101 to perform a first operation when a first event is triggered.

[0154] In some embodiments, network device 102 may determine that the cell or frequency band currently in which terminal 101 is located is in a congested state. In this case, network device 102 may send first information to terminal 101 to indicate that terminal 101 will not perform the first operation if the first event is triggered.

[0155] In some embodiments, the first operation may include at least one of the following: performing cell selection via the master receiver, performing cell reselection via the master receiver, and performing cell redirection via the master receiver.

[0156] In some embodiments, the first information may be carried in at least one of the following: LP-WUS, paging message, or system message.

[0157] In some embodiments, the first information may be carried in the LP-WUS. In some embodiments, network device 102 may send the LP-WUS to terminal 101, and terminal 101 may receive the LP-WUS via the LP-WUS. The LP-WUS carries the first information.

[0158] In some embodiments, the first information may be carried in the paging message. In some embodiments, network device 102 may send a paging message to terminal 101, and terminal 101 may receive the paging message through a master receiver. The paging message carries the first information. In some embodiments, the paging message carrying the first information may be downlink control information for paging. In some embodiments, the paging message carrying the first information may be a paging message containing identification information of terminal 101.

[0159] In some embodiments, the first information may be carried in a system message. In some embodiments, terminal 101 may receive a system message from network device 102, which may contain the first information. In some embodiments, the system message may be one of the following: a master information block (MIB) or a system information block (SIB).

[0160] In some embodiments, the first information and the second information can be sent to the terminal 101 simultaneously by the network device 102. For example, the network device 102 can send a system message to the terminal 101, which may contain the first information and the second information. In other words, steps S201 and S202 can be executed simultaneously. In some embodiments, the first information and the second information can be sent to the terminal 101 separately by the network device 102. For example, the network device 102 can send the first information to the terminal 101 first, and then send the second information to the terminal 101. In other words, step S202 can be executed first, and then step S201 can be executed. For example, the network device 102 can send the second information to the terminal 101 first, and then send the first information to the terminal 101. In other words, step S201 can be executed first, and then step S202 can be executed.

[0161] In some embodiments, step S202 may be executed, and the first information may be displayed and indicated by the network device 102. In some embodiments, step S202 may not be executed, and the first information may be implicitly indicated or may be agreed upon by a protocol.

[0162] In some embodiments, the first information can be implicitly indicated by the second information. In some embodiments, if step S201 is executed, then terminal 101 can obtain the second information. In this case, sending the second information can instruct network device 102 to want terminal 101 to perform the first operation. In some embodiments, if step S201 is not executed, then terminal 101 may not obtain the second information. In this case, not sending the second information can instruct network device 102 not to want terminal 101 to perform the first operation, i.e., to remain in the current cell.

[0163] In some embodiments, step S202 may not be performed. In some embodiments, terminal 101 may not have obtained the first information.

[0164] In step S203, network device 102 sends a paging message to terminal 101.

[0165] In some embodiments, network device 102 may send a paging message. In some embodiments, the paging message may be sent by network device 102, but is not limited to this, and may also be sent by other entities.

[0166] In some embodiments, terminal 101 may receive paging messages. In some embodiments, paging messages may be received by terminal 101, but are not limited thereto, and may also be received by other entities.

[0167] In some embodiments, a paging message can be used to paging terminal 101.

[0168] In some embodiments, a paging message can be used to wake up terminal 101 from a deep sleep state. For example, the paging message can be LP-WUS. In some embodiments, in a deep sleep state, the main receiver of terminal 101 is not working, and the LP-WUS of terminal 101 is working. Terminal 101 can receive LP-WUS from network device 102 via LP-WUS.

[0169] In some embodiments, a paging message can be used to page terminal 101 which is in an idle or inactive state. In some embodiments, in the idle or inactive state, the master receiver of terminal 101 is active, and the LP-WUR of terminal 101 may or may not be active. Terminal 101 can receive the paging message from network device 102 through the master receiver.

In some embodiments, step S203 can be executed, and then terminal 101 can receive a paging message. In this case, terminal 101 can determine that the first event has been triggered.

[0174] In some embodiments, the first event may include: the terminal 101 having uplink data to be sent. In some embodiments, when the terminal 101 has uplink data to be sent, the terminal 101 may determine that the first event has been triggered.

[0175] In some embodiments, the first event may include: the signal quality detected by LP-WUR is lower than a first threshold. In some embodiments, if terminal 101 detects that the signal quality of a signal is lower than the first threshold via LP-WUR, terminal 101 may determine that the first event has been triggered.

[0176] In some embodiments, during deep sleep, terminal 101 can detect and measure the signal via LP-WUR. If the signal quality is below a first threshold, terminal 101 can determine that a first event has been triggered.

[0177] In some embodiments, the signal detected by terminal 101 via LP-WUR may include LP-SS. In some embodiments, LP-SS may be used for RRM measurement. In one example, terminal 101 may detect LP-SS via LP-WUR and perform RRM measurement based on LP-SS to obtain signal quality. It is understood that terminal 101 may also detect other signals via LP-WUR, and this disclosure does not specifically limit the scope of such detection.

In some embodiments, if the signal quality detected by LP-WUR is lower than the first threshold, the terminal 101 may determine, based on the first information, not to perform the first operation.

[0190] In some embodiments, the first information may indicate that, in the event of a first event being triggered, terminal 101 will not perform the first operation. In some embodiments, in the event of a first event being triggered, terminal 101 may determine, based on the first information, not to perform the first operation. For example, terminal 101 may determine not to perform the first operation through the main receiver.

[0191] In some embodiments, according to the agreement, when terminal 101 is paged by the network, terminal 101 may determine to perform a first operation.

[0192] In some embodiments, according to the protocol, if terminal 101 has uplink data to be sent, terminal 101 may determine to perform the first operation;

[0193] In some embodiments, according to the agreement, if the signal quality detected by LP-WUR is lower than a first threshold, terminal 101 may determine to perform a first operation.

[0195] In step S206, terminal 101 performs the first operation.

[0196] In some embodiments, if it is determined that the first operation will be performed, the terminal 101 may perform the first operation.

[0197] In some embodiments, upon determining that a first event has been triggered, terminal 101 may perform a first operation based on second information. In some embodiments, terminal 101 may perform cell selection, cell reselection, or cell redirection based on the second information.

[0198] In some embodiments, the second information may include a cell identifier. For example, the second information may indicate a cell for cell selection, cell reselection, or cell redirection via the cell identifier. In this case, the cell indicated by the cell identifier is determined as the target cell of the first operation. In some embodiments, the terminal 101 may determine the cell indicated by the cell identifier as the target cell for cell selection, cell reselection, or cell redirection. For example, if the cell identifier in the second information indicates cell 1, then the terminal 101 may determine cell 1 as the target cell.

[0199] In some embodiments, the second information may include a cell list, and this cell list may be a whitelist. In this case, at least one cell in the cell list is determined as the target cell for the first operation. In some embodiments, the terminal 101 may determine one cell in the cell list as the target cell for cell selection, cell reselection, or cell redirection. For example, if the cell list in the second information may include cell 1, cell 2, cell 3, and cell 4, then the terminal 101 may determine one of cell 1, cell 2, cell 3, and cell 4 as the target cell.

[0200] In some embodiments, terminal 101 may compare the signal quality measured in at least one cell in the cell list and determine the cell with the best signal quality as the target cell for cell selection, cell reselection, or cell redirection.

[0201] In some embodiments, the second information may include a cell list, and this cell list may be a blacklist. In this case, at least one cell in the cell list cannot be identified as the target cell of the first operation. In some embodiments, the terminal 101 may not identify any cell in the cell list as the target cell for cell selection, cell reselection, or cell redirection. For example, if the cell list in the second information may include cell 1, cell 2, cell 3, and cell 4, then the target cell identified by the terminal 101 is not any one of cell 1, cell 2, cell 3, or cell 4.

[0202] In some embodiments, the second information may include frequency point information. For example, the second information may indicate a frequency point for cell selection, cell reselection, or cell redirection. In this case, the frequency point indicated by the frequency point information is determined as the target frequency point for the first operation. In some embodiments, the terminal 101 may determine the frequency point indicated by the frequency point information as the target frequency point for cell selection, cell reselection, or cell redirection. Then, the terminal 101 may determine a suitable cell on the target frequency point as the target cell. For example, if the frequency point information indicates frequency point 1, then the terminal 101 may determine frequency point 1 as the target frequency point and determine the cell on frequency point 1 as the target cell.

[0203] In some embodiments, the frequency information indicated by the second information can be used for cell redirection. In this case, the target cell can be a cell on the target frequency that satisfies the S-criterion. In some embodiments, the S-criterion can be used to determine whether a cell is suitable for terminal 101 to camp on.

[0204] In some embodiments, the frequency information indicated by the second information can be used for cell reselection. In some embodiments, the terminal 101 can determine, according to a protocol, that the frequency indicated by the frequency information has the highest priority. In some embodiments, the second information may further include priority information. The terminal 101 can determine, according to the priority information, that the frequency indicated by the frequency information has the highest priority.

[0205] In some embodiments, terminal 101 can perform frequency point measurements and sort them according to priority based on cell reselection criteria, and determine the cell with the best signal quality as the target cell for cell reselection. In some embodiments, terminal 101 can perform measurements of high-priority frequency points first, followed by measurements of low-priority frequency points. If a cell with signal quality higher than a threshold exists among the high-priority frequency points, terminal 101 can determine that cell as the target cell for cell reselection. In one example, terminal 101 can determine that the frequency point indicated by the frequency point information has the highest priority. Then, if the signal quality of a cell on that frequency point is greater than the threshold, terminal 101 can determine that cell as the target cell. For example, the frequency point information can indicate frequency point 1, and terminal 101 determines that frequency point 1 has the highest priority. Then, if the signal quality of cell 1 on frequency point 1 is greater than the threshold, cell 1 on frequency point 1 can be determined as the target cell for reselection.

[0206] In some embodiments, the second information may include a frequency point list, and this frequency point list may be a whitelist. In this case, at least one frequency point in the frequency point list is determined as the target frequency point of the first operation. In some embodiments, the terminal 101 may determine the cell with the best signal quality among the cells of at least one frequency point in the frequency point list as the target frequency point for cell selection, cell reselection, or cell redirection. For example, the frequency point list in the second information may include frequency point 1, frequency point 2, frequency point 3, and frequency point 4, then the terminal 101 may determine the cell with the best signal quality among the cells of frequency point 1, frequency point 2, frequency point 3, and frequency point 4 as the target cell.

[0207] In some implementations, the second information may also include priority information. For example, the second information may include a list of frequency points and priority information. In some embodiments, the priority information may indicate the priority of each frequency point in the list.

[0208] In some embodiments, terminal 101 can perform frequency point measurements and sort them according to the priority of each frequency point in the frequency point list based on cell reselection criteria, and determine the cell with the best signal quality as the target cell for cell reselection. In some embodiments, terminal 101 can perform measurements of high-priority frequency points first, followed by measurements of low-priority frequency points. If there is a cell with signal quality higher than a threshold among the high-priority frequency points, terminal 101 can determine that cell as the target cell for cell reselection. In one example, terminal 101 can determine that the frequency point indicated by the frequency point information has the highest priority. Then, if the signal quality of a cell on that frequency point is greater than the threshold, terminal 101 can determine that cell as the target cell. For example, the frequency point list may include frequency point 1, frequency point 2, frequency point 3, and frequency point 4, and the priority information indicates that frequency point 1 has a first priority, frequency point 2 has a first priority, frequency point 3 has a second priority, and frequency point 4 has a third priority. Terminal 101 can first perform detection and measurement for frequency point 1. If a cell with signal quality greater than the threshold exists at frequency point 1, that cell can be identified as the target cell for cell reselection; otherwise, terminal 101 can perform detection and measurement for frequency point 2. If a cell with signal quality greater than the threshold exists at frequency point 2, that cell can be identified as the target cell for cell reselection; otherwise, terminal 101 can perform detection and measurement for frequency point 3. If a cell with signal quality greater than the threshold exists at frequency point 3, that cell can be identified as the target cell for cell reselection; otherwise, terminal 101 can perform detection and measurement for frequency point 4. If a cell with signal quality greater than the threshold exists at frequency point 4, that cell can be identified as the target cell for cell reselection.

[0209] In some embodiments, the frequency points in the frequency point list of the second information may only support the primary receiver. In this case, the terminal 101 can determine the target cell on these frequency points that only support the primary receiver.

[0210] In some embodiments, the frequency points in the frequency point list of the second information may support both the main receiver and LP-WUR. In this case, terminal 101 can determine the target cell on these frequency points that support both the main receiver and LP-WUR.

[0211] In some embodiments, the second information may include a frequency point list, and this frequency point list may be a blacklist. In this case, at least one frequency point in the frequency point list is not determined as the target frequency point of the first operation. For example, the frequency point list in the second information may include frequency point 1, frequency point 2, frequency point 3, and frequency point 4, then the terminal 101 may not determine the cells of frequency points 1, 2, 3, and 4 as target cells.

[0212] In some embodiments, the second information may include frequency point characteristic information. The frequency point characteristic information may indicate whether each frequency point supports a master receiver and / or LP-WUR, and indicate the priority among the frequency points. For example, the frequency point list may include frequency point 1, frequency point 2, frequency point 3, and frequency point 4. The frequency point characteristic information may indicate that frequency points 1 and 2 support both a master receiver and LP-WUR, and may indicate that frequency points 3 and 4 support only a master receiver. The frequency point characteristic information may also indicate that frequency points 3 and 4 have high priority. Terminal 101 may preferentially identify the cells of frequency points 3 and 4 as target cells. If there are no suitable cells at frequency points 3 and 4 (e.g., cells with signal quality greater than a threshold), terminal 101 may identify the cells of frequency points 1 and 2 as target cells.

[0213] In some embodiments, terminal 101 may determine not to perform the first operation. In this case, step S206 may not be performed, and terminal 101 may remain in the current cell.

[0214] The communication method of this embodiment can be implemented through steps S201 to S206.

[0259] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0260] In the following, the technical solutions of the embodiments of this disclosure will be described by way of specific implementation.

[0261] In some embodiments, the network (i.e., network device) sends auxiliary information to assist the terminal or the protocol in determining whether to perform a first operation under specific circumstances.

[0262] In some embodiments, the first operation is cell selection, reselection, or redirection.

[0263] In some embodiments, a specific triggering event (i.e., the first event) is triggered for the following reasons: a network paging is detected; there is uplink data to be sent; a first transceiver detects that the signal is below a threshold, wherein the first transceiver is a low-power transceiver.

[0264] In some embodiments, the terminal will turn on the master transceiver under the above-mentioned triggering event.

[0265] In some embodiments, after a terminal is triggered under certain circumstances, it may continue to remain in the original cell or perform the first operation, such as cell reselection, which may be agreed upon by the protocol.

[0266] In some embodiments, the protocol stipulates that terminals supporting LR (i.e., LP-WUR) will perform the first operation of MR (i.e., master receiver) under the above triggering scenario.

[0267] In some embodiments, the protocol stipulates that a first operation is triggered if a paging is detected. This allows a paging response to be initiated in the target cell of the first operation as quickly as possible, avoiding overload on the original cell.

[0268] In some embodiments, the protocol stipulates that a first operation is triggered if there is uplink data transmission. This allows a paging response to be initiated in the target cell of the first operation as quickly as possible, avoiding overload on the original cell.

[0269] In some embodiments, the protocol stipulates that if the first transceiver detects a signal below a threshold, the first operation need not be triggered.

[0270] In some embodiments, whether a terminal continues to remain in the original cell or undergoes cell reselection after a specific condition is triggered can be indicated by the network.

[0271] In some embodiments, the network instructs terminals that support LR to perform cell reselection for MR under specific triggering scenarios (at which time, the cell or frequency band is already in a congested state).

[0272] In some embodiments, the network instructs terminals that support LR not to perform cell reselection for MR under specific triggering scenarios (at which time, the cell or frequency band is not in a congested state).

[0273] In some embodiments, after a specific condition is triggered, the terminal can be notified of whether to continue in the original cell or to perform a cell reselection network indication in the following manner.

[0274] In some embodiments, a display indication message is used.

[0275] In some embodiments, the indication may be in the wake-up signal LP-WUS.

[0276] In some embodiments, the indication may be in a paging message (including paging DCI and paging messages carrying the UE ID).

[0277] In some embodiments, the instruction may be in a system message.

[0278] In some embodiments, implicit indication messages are used.

[0279] In some embodiments, if the information for the network-assisted terminal to perform the first operation is not sent, it means that the network wants the UE to remain in the original cell (i.e., the original cell is not congested).

[0280] In some embodiments, if the information for the network-assisted terminal to perform the first operation is sent, it means that the network wants the UE to perform cell reselection (i.e., the original cell was congested).

[0281] In some embodiments, information that the network assists the terminal in performing a first operation (i.e., second information), such as frequency point information indicating that the network instructs the terminal to enable MR and perform redirection after a specific event is triggered, is used by the network to implicitly indicate whether it wants the terminal to continue to stay in the original cell or to perform the first operation, such as cell reselection.

[0282] In some embodiments, the terminal behavior is as follows: if the terminal determines that a first operation needs to be performed, then after enabling MR, the first operation is performed, that is, the service is initiated in the target cell of the first operation to avoid overloading the original cell.

[0283] If the terminal determines that the first operation is not required, then after enabling MR, it will continue to remain in the original cell.

[0284] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, this disclosure proposes an apparatus including units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed, including units or modules for implementing the steps performed by the network device in any of the above methods.

[0285] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0286] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a central processing unit, microprocessor, graphics processing unit (GPU) (which can be understood as a type of microprocessor), or digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device, such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc.
