"First" and "second" do not restrict whether the "fields" they modify are in the same message, nor do they restrict the order of "first field" and "second field." Similarly, if the descriptive object is a "level," the ordinal numbers preceding "level" in "first level" and "second level" do not restrict the priority between "levels." Furthermore, the number of descriptive objects is not limited by ordinal numbers and can be one or more. For example, in "first device," the number of "devices" can be one or more. Furthermore, the objects modified by different prefixes can be the same or different. For example, if the object being described is "device", then "first device" and "second device" can be the same device or different devices, and their types can be the same or different. Similarly, if the object being described is "information", then "first information" and "second information" can be the same information or different information, and their content can be the same or different.

[0137] Figure 1 is a schematic diagram of the architecture of a communication system provided according to an embodiment of the present disclosure. As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.

[0138] In some embodiments, terminal 101 includes a main receiver (MR) and an LP-WUR.

[0139] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0140] In some embodiments, network device 102 may be an access network device.

[0141] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0142] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0143] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0144] In some embodiments, the communication system 100 described above may be a 4G communication system, a 5G communication system, or a 6G communication system. It should be noted that the communication system 100 may also be other communication systems, and this disclosure does not specifically limit them.

[0145] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0146] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or some of the main components in the communication system 100, but are not limited thereto. The main components shown in FIG1 are illustrative. The communication system 100 may include all or some of the main components in FIG1, or may include other main components other than those in FIG1. ​​The number and form of each main component are arbitrary. Each main component may be physical or virtual. The connection relationship between the main components is illustrative. The main components may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0147] 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), Future generation 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).

[0148] 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.

[0149] 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 sequences 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] Therefore, how to enable the terminal to quickly determine the cell to which it is camped is a technical problem that urgently needs to be solved.

[0154] Figure 2 is an interactive schematic diagram of the communication method provided according to an embodiment of the present disclosure. The communication method involved in this embodiment can be applied to a communication system 100. As shown in Figure 2, the communication method of this embodiment includes steps S201 to S204.

[0155] In step S201, network device 102 sends first information to terminal 101.

[0156] In some embodiments, network device 102 may send first information. In some embodiments, the first information may be sent by network device 102, but is not limited thereto, and may also be sent by other entities.

[0157] In some embodiments, terminal 101 may receive first information. In some embodiments, the first information may be received by terminal 101, but is not limited thereto, and may also be received by other entities.

[0158] In some embodiments, the first information may be used by the terminal 101 to perform a first operation. In some embodiments, the first information may be used to assist the terminal 101 in performing the first operation. In some embodiments, the first information may be used for the terminal 101 to consider in order to perform the first operation.

[0159] 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 first information may be used by terminal 101 to perform cell selection, cell reselection, or cell redirection.

[0160] In some embodiments, the first information may 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 first information may be used to assist the terminal 101 in performing a first operation when the first event is triggered. In some embodiments, the first information may be used to assist the terminal 101 in performing a first operation when the first event is triggered.

[0161] In some embodiments, the name of the first information is not limited, and it may be, for example, auxiliary information, reference information, etc.

[0162] 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.

[0163] In some embodiments, the first 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.

[0164] In some embodiments, the first information may include a cell identifier. This cell identifier may indicate a cell. In one example, the cell identifier in the first information may be a cell ID. For example, the cell identifier may indicate cell 1.

[0165] In some embodiments, the first 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.

[0166] In some embodiments, the cell list indicated by the first information may be a whitelist. In this case, cells in the cell list indicated by the first information may be used as the first cells for 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 may be used as the first cells for terminal 101 to perform the first operation.

[0167] In some embodiments, the cell list indicated by the first information may be a blacklist. In this case, cells in the cell list indicated by the first information cannot be used as the first cell for 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 the first cell for terminal 101 to perform the first operation.

[0168] In some embodiments, the first cell may be the target cell of the first operation. In other words, the first cell may be the cell where the terminal 101 camps after the first operation. For example, the first cell may be a cell determined through cell selection, cell reselection, or cell redirection.

[0169] In some embodiments, the frequency points in the blacklist of cells may be overloaded cells.

[0170] In some embodiments, the first 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 first information may indicate the center frequency and / or bandwidth of the frequency point. In one example, the frequency point information in the first information may indicate the index value of the frequency point.

[0171] In some embodiments, the first 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. It is understood that the frequency point indicated by the frequency point information having the highest priority means that in the first operation, the terminal 101 may preferentially measure and / or select the frequency point indicated by the frequency point information. For example, the terminal 101 may preferentially measure the signal strength and / or signal quality of the frequency point indicated by the frequency point information. For example, the terminal 101 may preferably select the cell on the frequency point indicated by the frequency point information as the first cell.

[0172] In some embodiments, the first 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.

[0173] In some embodiments, the first 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.

[0174] 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.

[0175] In some embodiments, the frequency list indicated by the first information may be a whitelist. In this case, the frequency points in the frequency list indicated by the first 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.

[0176] In some embodiments, the frequency list indicated by the first information may be a blacklist. In this case, the frequencies in the frequency list indicated by the first 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.

[0177] In some embodiments, the frequency points in the blacklist of frequency points may be frequency points that are overloaded.

[0178] 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.

[0179] In some embodiments, the first 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.

[0180] 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.

[0181] 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.

[0182] In some embodiments, the first information may be carried in at least one of the following: a system message or an RRC message.

[0183] In some embodiments, terminal 101 may receive a system message from network device 102, which may contain first information.

[0184] In some embodiments, the system message can be one of the following: a master information block (MIB) or a system information block (SIB). In one example, the system message can be an SIB4 message.

[0185] In some embodiments, the system message may further include cell configuration information. In some embodiments, where the first 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.

[0186] In some embodiments, terminal 101 may receive an RRC message from network device 102, the RRC message may contain first information.

[0187] In some embodiments, the RRC message may be an RRC release message.

[0188] In some embodiments, the first 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 first information from the network device 102 through the main receiver. In some embodiments, the terminal 101 may receive the first information under other circumstances, which are not specifically limited in this disclosure.

[0189] In step S202, network device 102 sends a paging message to terminal 101.

[0190] 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.

[0191] 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.

[0192] In some embodiments, a paging message can be used to paging terminal 101.

[0193] 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.

[0194] In some embodiments, a paging message can be used to page terminal 101 which is in an idle or inactive state. For example, the paging message can be a paging message. 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.

[0195] In some embodiments, step S202 may be omitted.

[0196] In step S203, terminal 101 determines that the first event has been triggered.

[0197] In some embodiments, terminal 101 may determine that a first event has been triggered.

[0198] In some embodiments, the first event may include: terminal 101 being paged by the network. In some embodiments, when terminal 101 is paged by the network, terminal 101 can determine that the first event has been triggered. In some embodiments, step S202 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.

[0199] 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.

[0200] 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.

[0201] 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.

[0202] 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.

[0203] In some embodiments, signal quality may be represented by at least one of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-interference-plus-noise ratio (SINR), and received signal strength indicator (RSSI).

[0204] In some embodiments, the first threshold may be pre-configured. In some embodiments, the first threshold may be set by network device 102.

[0205] In step S204, terminal 101 performs the first operation.

[0206] In some embodiments, upon determining that a first event has been triggered, terminal 101 may perform a first operation based on the first information. In some embodiments, terminal 101 may perform cell selection, cell reselection, or cell redirection based on the first information.

[0207] In some embodiments, the first information may include a cell identifier. For example, the first 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 first cell for the first operation. In some embodiments, the terminal 101 may determine the cell indicated by the cell identifier as the first cell for cell selection, cell reselection, or cell redirection. For example, if the cell identifier in the first information indicates cell 1, then the terminal 101 may determine cell 1 as the first cell.

[0208] In some embodiments, the first 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 first cell for the first operation. In some embodiments, the terminal 101 may determine a cell in the cell list as the first cell for cell selection, cell reselection, or cell redirection. For example, if the cell list in the first 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 first cell.

[0209] 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 first cell for cell selection, cell reselection, or cell redirection.

[0210] In some embodiments, the first 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 determined as the first cell for the first operation. In some embodiments, the terminal 101 may not determine any cell in the cell list as the first cell for cell selection, cell reselection, or cell redirection. For example, if the cell list in the first information may include cell 1, cell 2, cell 3, and cell 4, then the first cell determined by the terminal 101 is not any one of cell 1, cell 2, cell 3, or cell 4.

[0211] In some embodiments, the first information may include frequency point information. For example, the first 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 first 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 first cell.

[0212] In some embodiments, the frequency information indicated by the first information can be used for cell redirection. In this case, the first 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.

[0213] In some embodiments, the frequency information indicated by the first 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 first 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.

[0214] 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 first 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 first 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 first 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 at frequency point 1 is greater than the threshold, cell 1 at frequency point 1 can be determined as the first cell for reselection.

[0215] In some embodiments, the first 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, if the frequency point list in the first 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 first cell.

[0216] In some implementations, the first information may also include priority information. For example, the first 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 of frequency points.

[0217] 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 first 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 first 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 first 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, then that cell can be identified as the first 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, then that cell can be identified as the first 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, then that cell can be identified as the first 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, then that cell can be identified as the first cell for cell reselection.

[0218] In some embodiments, the frequency points in the frequency point list of the first information may only support the primary receiver. In this case, the terminal 101 can determine the first cell on these frequency points that only support the primary receiver.

[0219] In some embodiments, the frequency points in the frequency point list of the first information may support both the main receiver and LP-WUR. In this case, terminal 101 can determine the first cell on these frequency points that support both the main receiver and LP-WUR.

[0220] In some embodiments, the first information may include a frequency point list, and the 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, if the frequency point list in the first 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 the first cell.

[0221] In some embodiments, the first 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 determine the cells of frequency points 3 and 4 as the first cells. If there are no suitable cells for frequency points 3 and 4 (e.g., cells with signal quality greater than a threshold), terminal 101 may determine the cells of frequency points 1 and 2 as the first cells.

[0262] In the following, the technical solutions of the embodiments of this disclosure will be described by way of specific implementation.

[0263] In some embodiments, the network (i.e., network device) sends auxiliary information to assist the terminal in performing a first operation under specific circumstances.

[0264] In some embodiments, the first operation includes cell selection, reselection, or redirection.

[0265] In some embodiments, a specific triggering event (i.e., the first event) is triggered for the following reasons:

[0266] A network paging request was detected;

[0267] There is upstream data to be sent;

[0268] The first transceiver (i.e., LP-WUR) detects that the signal is below the threshold; the first transceiver is a low-power transceiver.

[0269] In some embodiments, the network notification terminal performs a first operation under specific circumstances, such as cell selection, cell reselection, or redirection to a specified cell list.

[0270] In some embodiments, a first operation may be instructed, such as instructing a specific cell to be reselected / redirected to; the terminal may then directly reselect / redirect to that cell.

[0271] In some embodiments, a specified list of cells may be indicated for cell reselection / cell redirection.

[0272] In some embodiments, a whitelist of cells can be indicated for cell reselection / cell redirection; here, because the network is aware of the cell load, the network can notify the terminal of a list of candidate cells to facilitate faster selection by the terminal.

[0273] In some embodiments, the terminal can compare the signal quality measured in the cell list and select the cell with the best signal quality as the target cell for cell reselection / cell redirection.

[0274] In some embodiments, a blacklist of cells can be specified for cell reselection. For example, if the network already knows which cells are overloaded, the terminal will avoid selecting blacklisted cells as target cells when performing the first operation.

[0275] In some embodiments, the network notifies the terminal to perform a first operation under specific circumstances, such as a list of frequency points for cell selection, cell reselection, or redirection.

[0276] In some embodiments, a first operation may be instructed, such as cell redirection to a band / frequency (preferred embodiment).

[0277] In some embodiments, the terminal will attempt to find a suitable cell on that frequency band / frequency.

[0278] In some embodiments, a cell whose signal quality exceeds a threshold, such as satisfying the S criterion, can be selected. In one embodiment, the terminal may not distinguish the priority level of the network notification band / frequency.

[0279] In some embodiments, a first operation may be instructed, such as a frequency band (preferred embodiment). Here, the terminal can select a suitable cell only on that frequency band, accelerating cell selection or reselection.

[0280] In some embodiments, the frequency band / frequency may be agreed upon by the protocol or indicated by the network as having the highest priority.

[0281] In some embodiments, the terminal may initiate measurement for the frequency band / frequency according to existing cell reselection criteria, i.e., according to priority level, and select the cell with the best signal quality as the target cell for the first operation after sorting according to priority level.

[0282] In some embodiments, if the cell signal of a high-priority frequency point in the network notification is higher than a threshold, it can be used as the target cell for the first operation.

[0283] In some embodiments, a first operation may be instructed, such as cell reselection of a frequency band / frequency list.

[0284] In some embodiments, without distinguishing priority levels, the terminal can select the cell with the strongest signal quality in these frequency bands / frequency bands as the first operation, such as reselecting the target cell.

[0285] In some embodiments, a first operation may be instructed, such as a frequency band / frequency list for cell reselection; the priority level of each frequency band may also be indicated.

[0286] In some embodiments, the priority level includes a priority level and a sub-priority level.

[0287] In some embodiments, the terminal may initiate measurement for the frequency band / frequency according to existing cell reselection criteria, i.e., according to priority level, and select the cell with the best signal quality as the target cell for the first operation after sorting according to priority level.

[0288] In some embodiments, if the cell signal of a high-priority frequency point in the network notification is higher than a threshold, it can be used as the target cell for the first operation.

[0289] In some embodiments, a first operation may be instructed to be performed, such as a list of frequency bands / frequency bands for cell reselection, wherein the frequency bands / frequency bands / frequency bands / frequency bands that only support MR (i.e., master receiver) and do not include frequency bands / frequency bands / frequency bands that support LR (i.e., LP-WUR).

[0290] In some embodiments, a first operation may be instructed, such as a blacklist of frequency bands for cell reselection. For example, if the network already knows which frequency bands are overloaded, the terminal will avoid selecting blacklisted frequency bands as target frequency bands when performing the first operation.

[0291] In some embodiments, the network notification terminal triggers a first operation under specific circumstances, such as the characteristics of cell / frequency point selection / reselection.

[0292] In some embodiments, a first operation may be instructed, such as a list of frequency bands / frequency bands for cell reselection; wherein for each frequency band / frequency band, the network indicates whether MR and / or LR are supported in that frequency band / frequency band.

[0293] In some embodiments, the network may also indicate the priority level of frequency points; for example, frequency bands / frequency bands that support MR are given high priority (because at this time it is desirable for the terminal to preferably select frequency bands / frequency bands that only support MR).

[0294] In some embodiments, the notification message is SIB4.

[0295] In some embodiments, auxiliary information for the network-notified terminal is communicated to the terminal in the following manner.

[0296] In some embodiments, the terminal is notified in a system message. In some embodiments, the terminal may be notified in a system message to perform a first operation after the MR is woken up, such as a frequency point for cell reselection, to speed up camping.

[0297] In some embodiments, the first operation can be appended to the system message, such as cell reselection configuration information, like RACH configuration. This can speed up the terminal's first operation process.

[0298] In some embodiments, the terminal is notified in a dedicated message.

[0299] In some embodiments, the terminal may be instructed to provide the above information in the RRC release message, such as instructing the terminal to perform a first operation, such as cell selection / reselection of a frequency band / frequency, wherein the frequency band / frequency is a frequency band / frequency that only supports MR; the terminal will attempt to find a suitable cell on that frequency band / frequency.

[0300] In some embodiments, the terminal may be instructed to provide the above information in the RRC release message, such as instructing the terminal to perform a first operation, such as selecting / reselecting a frequency band / frequency that supports LR; the terminal will attempt to find a suitable cell on that frequency band / frequency.

[0301] 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.

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.
