Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a cell selection or reselection method, apparatus, device, and readable storage medium. Background Technology

[0002] In existing cell selection or reselection mechanisms, terminals select or reselect cells based on the frequency priority deployed by the operator. However, the introduction of Low-Power Wake-Up Signal (LP-WUS), Low-Power Synchronization Signal (LP-SSB), Low-Power Wake-Up Receiver (LP-WUR), or Low-Power Receiver (LR) may present some challenges. Specifically, since the low-power receivers corresponding to LR, LP-WUS, LP-SS, or LP-WUR may not support all frequency bands, the terminal may camp on a frequency band that does not support LP-WUS, LP-SS, LP-WUR, or LR during cell selection or reselection. If the terminal camps on a band that does not support LP-WUS, LP-SS, LP-WUR, or LR, it will be unable to utilize these low-power functions, thus failing to achieve the expected power-saving gains.

[0057] It is worth noting that the technology described in this application is not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), or other systems, such as NTN systems, vehicle-to-everything (V2X), vehicle-to-everything (V2X), machine-type communications (MTC), the Internet of Things (IoT), machine-to-machine (M2M), or future mobile communication systems. As a possible application scenario, NTN systems may include satellite systems. Based on satellite altitude, i.e., satellite orbital altitude, satellites can be classified into highly elliptical orbit (HEO) satellites, geosynchronous orbit (GEO) satellites, medium Earth orbit (MEO) satellites, and low Earth orbit (LEO) satellites. In addition, NTN systems may also include non-terrestrial network-side equipment (or airborne network-side equipment) such as high-altitude platform station (HAPS) communication systems. The non-terrestrial network-side equipment involved in this application is not limited to the examples mentioned above.

[0058] To better understand the embodiments of this application, the following technical points will be introduced first:

[0059] 1) Regarding the selection and reselection of communities.

[0060] 1. Initial cell selection process.

[0061] The terminal scans all radio frequency (RF) channels one by one according to its capabilities (the scanning order is not specified in the protocol) to find a suitable New Radio (NR) cell. Within each scanned carrier frequency, the terminal only needs to search for the cell with the strongest signal quality. Once a suitable cell is found, the terminal selects that cell to camp on and stops the initial cell selection process; that is, unscanned RF channels are no longer needed.

[0062] The suitable cell must meet at least all of the following conditions:

[0063] - The signal quality of the cell meets the preset conditions; the signal quality includes at least one of the following: Reference Signal Receiving Power (RSRP) and Reference Signal Receiving Quality (RSRQ);

[0064] - The terminal can obtain the necessary system information, which includes at least the Master Information Block (MIB) and the System Information Block (SIB)1;

[0065] - The cellbar information element (IE) in the system information (which can be set to either barred or notbarred) is set to notbarred, meaning that the cell is not barred from attaching or accessing.

[0066] 2. Community re-selection process.

[0067] The terminal evaluates each frequency point in turn, starting from the highest priority frequency point, based on the frequency point priority provided by the network, to see if there is a suitable target cell for reselection. Only suitable cells can be used as target cells for reselection.

[0068] Different frequency points can be configured with the same or different frequency priorities.

[0069] Specifically:

[0070] When a terminal is camped on a serving cell, if there is a higher priority NR or LTE cell on a frequency point that satisfies the condition that the cell signal quality (Squal) > threshold Thresh for a certain period of time... X,HighQ ,or,

[0071] If a higher-priority NR or other Radio Access Technology (RAT) cell on a frequency band meets the signal quality (S) requirement of the currently serving cell for a given period of time... rxlev Threshold value Thresh X,HighP If the terminal has been camped on the current serving cell for more than one second, then it will initiate a reselection process to a cell on a higher priority NR or other RAT frequency point.

[0072] 2) Regarding signal quality measurement (S-measure).

[0073] In LTE and NR systems, the relevant protocols define the configurations related to idle and inactive state measurements, as well as the measurement triggering conditions for neighboring cells. The relevant protocols also define the measurement configurations and measurement reporting conditions for connected state measurements.

[0074] When determining whether to select a reselection target for a cell based on measurements of intra-frequency neighboring cells, if the serving cell satisfies S... rxlev >Same frequency measurement threshold (S) IntraSearchP and cell selection signal quality value (S) qual Inter-frequency measurement threshold (S) IntraSearchQ If the threshold is not met, the terminal will choose not to perform measurements of neighboring cells on the same frequency. Otherwise, if the threshold is lower than the threshold, measurements of neighboring cells on the same frequency will need to be performed.

[0075] For inter-frequency and inter-RAT scenarios, when the priority is higher than the serving frequency and RAT, the terminal performs measurements of neighboring cells according to the measurement requirements defined in the relevant protocols. When the priority is equal to or lower than the serving frequency and RAT, the terminal performs measurements of neighboring cells when the serving cell satisfies Srxlev > inter-frequency measurement signal amplitude threshold (S...). nonIntraSearchP ), and S qual Different frequency measurement signal strength threshold (S) nonIntraSearchQ If the threshold is not met, the UE will choose not to perform the neighboring cell measurement; otherwise, if the threshold is not met, the neighboring cell measurement needs to be performed.

[0076] The aforementioned neighbor cell measurement threshold is optional to configure on the network side. When it is not configured, it is defined in the relevant protocol that when the measurement results of this cell fail to meet the S criterion multiple times consecutively, the measurement of neighbor cells will be triggered.

[0077] In connected mode, the terminal checks the measurement results (RSRP or RSRQ) of the special cell (SpCell) and the configured S-measure thresholds (s-MeasureConfig). If the measurement result is lower than the configured threshold, the terminal calculates and reports the measurement result according to the measurement configuration and measurement reporting configuration. Therefore, if the measurement result is higher than the threshold, no corresponding measurement or measurement reporting is required.

[0078] 3) Regarding LP-WUS technology.

[0079] LP-WUS is a low-power wake-up signal, received by a low-power receiver (LP WUR), used to wake up the main communication module, etc. For example, a terminal may contain two modules: the first is the main communication module, used for transmitting and receiving mobile communication data; the second is a low-power wake-up receiver module, used to receive the low-power wake-up signal and low-power beacon signal sent by the transmitter. The low-power wake-up signal is used to wake up the receiver's main communication module, and the low-power beacon signal provides time reference information and other information for receiving the low-power wake-up signal, and can also provide wake-up link management.

[0080] The first module remains in a powered-off state unless awakened by the second module, and does not send or receive data. When downlink data arrives, the second module detects a wake-up signal sent by the transmitter, and this wake-up signal contains information about the terminal. The second module then triggers the first module to switch from a powered-off state to a powered-on state, enabling data reception and transmission. The second module can be continuously or intermittently powered. When powered on, the second module can receive low-power wake-up signals and low-power beacon signals.

[0081] 4) Regarding low-power receivers.

[0082] A low-power receiver, also known as a low-power wake-up radio (LP-WUR) or near-zero power wake-up radio (AZP-WUR), operates on the principle that the receiver comprises a first module and a second module. The first module is the main communication module, used for transmitting and receiving mobile communication data. The second module is a low-power receiver module (also called a low-power wake-up receiver module), used to receive the wake-up signal. In power-saving mode, the terminal activates the low-power receiver module to listen for LP-WUR and disables the main communication module. When downlink data arrives, the network sends a wake-up signal to the terminal. After detecting the wake-up signal through the low-power receiver module, the terminal triggers the main communication module to turn on after a series of checks, while the low-power receiver module turns off. The low-power wake-up receiver module can be continuously or intermittently activated, and when activated, it can receive low-power wake-up signals.

[0083] 5) Regarding low-power wake-up signals.

[0084] To reduce receiving activity in standby mode and effectively shut down the RF and baseband modules, thereby significantly reducing power consumption during communication reception, this can be achieved by introducing a near-zero power receiver into the terminal's receiving module. This near-zero power receiver eliminates the need for complex signal detection (such as amplification, filtering, and quantization) in the RF module and signal processing in the baseband module, relying solely on passive matched filtering and low-power signal processing.

[0085] On the base station side, by triggering a wake-up signal on demand, the receiver with near-zero power can be activated to receive the activation notification, thereby triggering a series of processes within the terminal, such as turning on the radio frequency transceiver and baseband processing modules.

[0086] Such wake-up signals are usually simple on-off keying (OOK) signals, so that the receiver can learn about the wake-up notification through simple energy detection and subsequent possible sequence detection and recognition processes.

[0087] The terms "system" and "network" used in the embodiments of this application are often used interchangeably, and the described technologies can be used with respect to the systems and radio technologies mentioned above, as well as other systems and radio technologies. The following description describes a New Radio (NR) system for illustrative purposes, and the term NR is used in most of the following description; however, these technologies can also be applied to systems other than NR systems, such as 6th generation (6G) systems. th Generation 6G communication system.

[0124] 5) The terminal uses LP-WUS, LP-SS, LP-WUR, or LR, or the terminal meets the conditions for entering LP-WUS, LP-SS, LP-WUR, or LR;

[0125] 6) The terminal expects to use LP-WUS, LP-SS, LP-WUR, or LR, or the terminal expects to achieve power saving or has power saving requirements.

[0126] In one embodiment of this application, the first criterion includes at least one of the following: the S criterion for cell selection, and the R criterion for cell reselection;

[0127] The first method includes at least one of the following:

[0128] 1) Select a first target cell whose first value is higher than a first threshold, or do not select a second target cell whose first value is higher than a first threshold, wherein the first value includes: the index used to evaluate signal quality in the S criterion;

[0129] In this context, selecting the first target cell with a first value higher than the first threshold can be understood as prioritizing the selection of the first target cell with a first value higher than the first threshold, while not selecting the second target cell with a first value higher than the first threshold can be understood as prioritizing the selection of the second target cell with a first value higher than the first threshold.

[0130] The first value mentioned above can be the S value in the S criterion of the cell selection mechanism. For example, the S value can include at least one of the following: the signal quality of the current serving cell (e.g., S). rxlev ), cell selection quality value (e.g., S) qual ).

[0131] S-criterion formula: S rxlev >0, and S qual >0. That is, if the S-value of a cell is greater than 0, it indicates that the cell is a suitable cell, i.e., a suitable cell for dwelling. As one possible implementation, S... rxlev and S qual The calculation formula is as follows:

[0132] S rxlev =Q rxlevmeas -(Q rxlevmin +Q rxlevminoffset )-P compensation ;

[0133] in:

[0134] S rxlev : The calculated cell selection receive level value;

[0135] Q rxlevmeasThe received signal strength value measured by the terminal is the measured reference signal receiving power (RSRP).

[0138] S qual =Q qualmeas –(Q qualmin +Q qualminoffset );

[0139] Q qualmeas This represents the Reference Signal Receiver Quality (RSRQ) value of the measured cell;

[0140] Q qualmin This parameter represents the minimum received signal quality; that is, it represents the minimum received signal quality required for cell selection and is used to control the ease or difficulty of cell selection.

[0141] Q qualminoffset , which represents the minimum received signal quality offset value.

[0142] It should be noted that due to the evolution of communication protocol versions, the S criterion formula and S... rxlev and S qual The calculation formula may change for various reasons. The formula given here is merely an example and does not limit the formula itself. This application does not limit the parameters and criteria for cell selection.

[0143] 2) Select a first target cell whose second value is higher than the second threshold, or do not select a second target cell whose second value is higher than the second threshold, wherein the second value includes the index used to evaluate signal quality in the R criterion.

[0144] In this context, selecting the first target cell with a second value higher than the second threshold can be understood as prioritizing the selection of the first target cell with a second value higher than the second threshold, while not selecting the second target cell with a first value higher than the first threshold can be understood as prioritizing the selection of the second target cell with a second value higher than the second threshold.

[0145] The second value mentioned above can be the R value in the R criterion of the cell reselection mechanism. For example, the R value can include at least one of the following: the R value of the serving cell (e.g., R...). s ), the R value of neighboring cells (e.g., R) n ).

[0146] As one possible implementation, the calculation formula in the R criterion is as follows:

[0147] R s =Q meas,s +Q hyst R n =Q meas,n –Qoffset;

[0148] Where: R s The service area's ranking score, R. n The ranking value of the neighboring cells of the serving cell;

[0149] Q meas,s For the measurement of the received signal quality of the serving cell;

[0150] Q meas,n The measured value of the received signal quality in the neighboring cell;

[0151] Q hyst The re-election process for the community is delayed;

[0152] Qoffset is the difference in the received signal quality requirements between two cells.

[0153] It should be noted that due to the evolution of communication protocol versions, the R criterion formula and R... s and R n The calculation formula may change for various reasons. The formula given here is merely an example and does not impose any limitations on the formula itself. This application does not limit the parameters and criteria for cell reselection.

[0154] In one embodiment of this application, when the number of first target cells with a first value higher than a first threshold is multiple (i.e., the number of first target cells satisfying the S criterion is multiple), or the number of first target cells with a second value higher than a second threshold is multiple (i.e., the number of first target cells satisfying the R criterion is multiple), the first method further includes at least one of the following: a third method, a fourth method, a fifth method, and a sixth method;

[0155] in,

[0156] 1) The third method refers to selecting the candidate first target cell with the largest first value from multiple candidate first target cells as the first target cell, wherein the multiple candidate first target cells satisfy the S criterion, or reselecting the candidate first target cell with the largest second value from multiple candidate first target cells as the first target cell, wherein the multiple candidate first target cells satisfy the R criterion;

[0157] 2) The fourth method refers to selecting or reselecting one or more first target cells from M candidate first target cells. The one or more first target cells are the cells with the most first beams among the M candidate first target cells. The M candidate first target cells are determined based on a first condition, which includes at least one of the following: during cell selection, the difference between the first value of the candidate first target cell and the first value of the first cell is less than a third threshold, and the first cell is the cell with the largest first value among all candidate first target cells; during cell reselection, the difference between the second value of the candidate first target cell and the second value of the second cell is within a fourth threshold, and the second cell is the cell with the largest second value among all candidate first target cells; M is greater than or equal to 1, and the measurement result of the first beam is higher than a fifth threshold, wherein the M candidate first target cells satisfy the S criterion or the R criterion; optionally, the first cell may be the same as or different from the second cell.

[0158] For example, in one embodiment, the terminal detects N candidate first target cells. The first target cell with the largest first value among the N candidate first target cells is compared with the first values ​​of the other candidate first target cells. Among the M candidate first target cells whose difference is less than a third threshold, the candidate first target cell with the most first beams is selected as the first target cell. Specifically, if the number of candidate first target cells with a difference less than the third threshold is less than M, all candidate first target cells with a difference less than the third threshold are selected; if the number of candidate first target cells with a difference less than the third threshold is more than M, any M candidate first target cells with a difference less than the third threshold or the M candidate first target cells with the smallest difference, i.e., the M candidate first target cells sorted downwards from the largest first value, are selected.

[0159] Optionally, if there are multiple first target cells determined in the fourth method, the first target cell with the largest first value is selected from the multiple first target cells, or the first target cell with the largest second value is reselected from the multiple first target cells.

[0160] 3) The fifth method refers to using the fourth method if the third or fourth threshold has been configured, or using the third method if the third or fourth threshold has not been configured.

[0161] 4) The sixth method refers to arbitrarily selecting or reselecting one candidate first target cell from multiple candidate first target cells as the first target cell.

[0162] In one embodiment of this application, selecting a first target cell with a first value higher than a first threshold includes selecting a first target cell with a first value higher than a first threshold when a second condition is met.

[0163] The second condition includes at least one of the following:

[0164] 1) There is no suitable cell on the first frequency point of the terminal, the priority of the first frequency point is higher than the frequency point priority of the local cell, or the priority of the first frequency point is the same as the frequency point priority of the local cell.

[0165] 2) The first target cell and this cell are neighboring cells;

[0166] 3) The frequency priority of the first target cell is the same as that of the frequency of this cell, or the frequency priority of the first target cell is lower than that of the frequency of this cell.

[0167] In one embodiment of this application, the method further includes:

[0168] The terminal determines at least one of the following through a seventh method: a first value of the second target cell, and a second value of the second target cell;

[0169] The seventh method includes at least one of the following:

[0170] 1) When determining the first value of the second target cell, the first value of the second target cell is reduced by a first offset (e.g., the first offset is expressed as Qoffset). temp express);

[0171] For example, the first value of the second target cell = the S value of the second target cell - the first offset, wherein the S value of the second target cell can be the S value of the second target cell determined based on existing S criteria, such as S... rxlev S qual .

[0172] Optionally, the S of the second target cell rxlev The calculation formula is as follows:

[0173] Q rxlevmeas -(Q rxlevmin +Q rxlevminoffset )-P compensation -Qoffset temp .

[0174] Optionally, the S of the second target cell qual The calculation formula is as follows:

[0175] S qual =Q qualmeas –(Q qualmin +Q qualminoffset -Qoffset temp When using the S criterion for cell selection, by reducing the first value of the second target cell by a first offset, the second target cell can be ranked lower because the first value of the second target cell is reduced by a first offset relative to the S value of the second target cell determined based on the existing S criterion.

[0176] 2) When determining the second value of the second target cell, the second value of the second target cell is reduced by a second offset (e.g., the second offset is expressed as Qoffset). temp ).

[0177] For example, the second value of the second target cell = the R value of the second target cell - the second offset, wherein the R value of the second target cell can be the R value of the second target cell determined based on existing R criteria, such as R... s R n .

[0178] Optionally, the R of the second target cell s The calculation formula is as follows:

[0179] R s =Q meas,s +Q hyst -Qoffset temp .

[0180] Optionally, the R of the second target cell n The calculation formula is as follows:

[0181] R n =Q meas,n –Qoffset-Qoffset temp .

[0182] When using the R criterion for cell reselection, the second value of the second target cell is reduced by a second offset. Since the second value of the second target cell is reduced by a second offset relative to the R value of the second target cell determined based on the existing R criterion, the ranking of the second target cell can be lower.

[0183] In one embodiment of this application, the method further includes:

[0184] The terminal determines at least one of the following through an eighth method: a first value of the candidate first target cell, and a second value of the candidate first target cell;

[0185] The eighth method includes at least one of the following:

[0186] 1) When determining the first value of the candidate first target cell, the first value of the candidate first target cell is increased by a third offset (e.g., the third offset is expressed as Qoffset). temp );

[0187] For example, the first value of the candidate first target cell = the S value of the first target cell + the third offset, wherein the S value of the first target cell can be the S value of the first target cell determined based on existing S criteria.

[0188] Optionally, the S of the candidate first target cell rxlev The calculation formula is as follows:

[0189] Q rxlevmeas -(Q rxlevmin +Q rxlevminoffset )-P compensation +Qoffset temp .

[0190] Optionally, the S of the candidate first target cell qual The calculation formula is as follows:

[0191] S qual =Q qualmeas –(Q qualmin +Q qualminoffset )+Qoffset temp .

[0192] When using the S criterion for cell selection, by adding a third offset to the first value of the candidate first target cell, the candidate first target cell can be ranked higher because the first value of the first target cell is increased by the third offset relative to the S value of the candidate second target cell determined based on the existing S criterion.

[0193] 2) When determining the second value of the candidate first target cell, the second value of the candidate first target cell is increased by a fourth offset (e.g., the fourth offset is expressed as Qoffset). temp );

[0194] For example, the second value of the candidate first target cell is equal to the R value of the first target cell plus a fourth offset, wherein the R value of the first target cell can be the R value of the first target cell determined based on existing R criteria.

[0195] Optionally, the R of the candidate first target cell s The calculation formula is as follows:

[0196] R s =Q meas,s +Q hyst +Qoffset temp .

[0197] Optionally, the R of the candidate first target cell n The calculation formula is as follows:

[0198] R n =Q meas,n –Qoffset+Qoffset temp .

[0199] When using the R criterion for cell reselection, by adding a fourth offset to the second value of the candidate first target cell, the candidate first target cell can be ranked higher because the second value of the first target cell is increased by a fourth offset relative to the R value of the candidate first target cell determined based on the existing R criterion.

[0200] 3) Determine the first value of the candidate first target cell based on the first parameter corresponding to the candidate first target cell, wherein the first parameter corresponding to the candidate first target cell is configured independently of the first parameters corresponding to other cells;

[0201] Optionally, the first parameter is a parameter used to determine the first value, such as a parameter used to calculate the S value in the S criterion in the cell selection mechanism. The value of the first parameter corresponding to the candidate first target cell may be the same as or different from the value of the first parameter corresponding to other cells.

[0202] 4) Determine the second value of the candidate first target cell based on the second parameter corresponding to the candidate first target cell. The second parameter corresponding to the candidate first target cell is configured independently of the second parameter corresponding to other cells.

[0203] Optionally, the second parameter is a parameter used to determine the second value, such as a parameter used to calculate the R value in the R criterion in the cell reselection mechanism. The value of the second parameter corresponding to the candidate first target cell may be the same as or different from the value of the second parameter corresponding to other cells.

[0204] In one embodiment of this application, the maximum value of the first parameter corresponding to the first target cell is less than the maximum value of the first parameter corresponding to other cells; thus, by using different first parameters, the first target cell can more easily satisfy the S criterion, or the second target cell can be made more difficult to satisfy the S criterion.

[0205] In another embodiment of this application, the maximum value of the second parameter corresponding to the first target cell is less than the maximum value of the second parameter corresponding to other cells. This allows the use of different second parameters to make it easier for the first target cell to satisfy the R criterion, or to make it more difficult for the second target cell to satisfy the R criterion.

[0206] In one embodiment of this application, the method further includes:

[0207] The terminal receives first information, which indicates at least one of the following:

[0212] It is understood that this application does not limit the specific values ​​of the first offset, second offset, third offset, and fourth offset mentioned above.

[0213] 5) The first parameter;

[0214] Optionally, the first parameter is a parameter used to determine the first value, such as a parameter used to calculate the S value in the S criterion in the cell selection mechanism, such as signal quality and a threshold, where signal quality includes at least one of Reference Signal Receiving Power (RSRP) and Reference Signal Receiving Quality (RSRQ).

[0215] 6) The second parameter;

[0216] Optionally, the second parameter is a parameter used to determine the second value, such as parameters used to calculate the R value in the R criterion in the cell reselection mechanism, for example, the cell selection signal quality, the signal quality of the current serving cell, and a threshold value.

[0217] 7) Enable or activate the seventh method;

[0218] 8) Enable or activate the eighth method.

[0219] Optionally, the first information is also used to indicate at least one of the following: 9) disable or deactivate the seventh method, 10) disable or deactivate the eighth method.

[0220] Understandably, the initial information can be sent to the terminal either explicitly or implicitly.

[0221] For example, the first information may be carried by at least one of the following: broadcast messages (such as system information), paging messages, early indication (PEI) messages, and dedicated radio resource control (RRC) messages.

[0222] Optionally, the advance indication message includes, but is not limited to, at least one of the following: wake-up signal, LP-WUS, LR, and paging early indication (PEI).

[0223] Optionally, RRC-specific messages may include, but are not limited to, at least one of the following: RRC reconfiguration message, RRC configuration message, RRC release message, and RRC suspend message.

[0224] For example, the first information can be implicitly sent to the terminal by sending any one of the methods described in 1) to 6) above. Optionally, the first information is a first offset or a second offset. After the terminal receives the first offset or the second offset, the terminal can determine the first value or the second value of the second target cell through the seventh method, and perform cell selection or reselection according to the first method.

[0225] In one embodiment of this application, the measurement quantity corresponding to the first parameter or the second parameter includes at least one of the following:

[0226] 1) The main receiver measures the reference signal;

[0228] 3) Orthogonal Frequency Division Multiplexing (OFDM) low-power receivers measure reference signals, low-power synchronization signals, or overlaid OFDM sequences.

[0229] For example, the reference signal includes, but is not limited to, at least one of the following: Synchronization Signal and PBCH block (SSB), Channel State Information-Reference Signal (CSI-RS), Tracking Reference Signal (TRS), and Demodulation Reference Signal (DMRS).

[0230] In one embodiment of this application, the method further includes:

[0231] The terminal receives second information, which indicates at least one of the following: the first target frequency point, and the second target frequency point.

[0232] In one embodiment, the second information is used to indicate at least one of the following: 1) the operating frequency of LP-WUS or LR or LP-SS or LR or the frequency supporting a first frequency (e.g., frequency F1); 2) the operating frequency of RRM measurement or cell selection or cell reselection or MR or the frequency supporting a second frequency (e.g., frequency F2).

[0233] In this application, by configuring a first target frequency or a second target frequency, the terminal can perform measurements according to the configured frequency. In this way, when the terminal performs cell selection or reselection, the terminal camps on cells of different frequency points or camps on cells of multiple frequency points based on the measurement results of the configured frequency points. This enables the terminal to use LP-WUS, LP-WUR, LP-SS, or LR in more scenarios and at more times to achieve the purpose of saving power.

[0234] Understandably, the second message can be sent to the terminal either explicitly or implicitly.

[0235] For example, the second information is carried by at least one of the following: broadcast message (such as system information), paging message, advance indication message, RRC dedicated message, where the RRC dedicated message may be an RRC reconfiguration message, an RRC configuration message, an RRC release message, or an RRC suspension message.

[0236] For example, the second information can be implicitly sent to the terminal by sending either the first target frequency or the second target frequency. Optionally, if the second information is the first target frequency or the second target frequency, then after the terminal receives the first target frequency or the second target frequency, the terminal can perform cell selection or reselection using the second method.

[0237] In one embodiment of this application, the method further includes:

[0238] The terminal determines at least one of the following based on the second information;

[0239] 1) Listen for low-power wake-up signals or low-power synchronization signals or use a low-power receiver on the first target frequency.

[0240] 2) Perform measurements at the first target frequency point;

[0241] Optionally, measurements at the first target frequency (e.g., the first frequency point) include at least one of the following: measuring at least one of LP-SS, SSB, and other reference signals at the first target frequency point. Optionally, further, measurements are performed at the first target frequency point via at least one of the main receiver (MR) and LR.

Optionally, further, at least one of SSB and other reference signals is measured at the second target frequency point.

[0244] 4) Select or reselect cells based on the measurement results at the first target frequency point;

[0245] In other words, the measurement results used in cell selection or reselection are the measurement results at the first target frequency (e.g., the first frequency).

[0246] Optionally, cell selection or reselection is performed based on the measurement results at the first target frequency, including one of the following: cell selection or reselection is performed based on the measurement results at the first target frequency and the first criterion; cell selection or reselection is performed based on the measurement results at the first target frequency and the first criterion, and the cell camped on the first target frequency is selected.

[0247] 5) Select or reselect cells based on the measurement results at the second target frequency point;

[0248] In other words, the measurement results used in cell selection or reselection are the measurement results on the second target frequency (e.g., the second frequency).

[0249] Optionally, cell selection or reselection is performed based on the measurement results at the second target frequency, including one of the following: cell selection or reselection is performed based on the measurement results at the second target frequency and the first criterion; cell selection or reselection is performed based on the measurement results at the second target frequency and the first criterion, and the cell camped on the second target frequency is selected.

[0252] In one implementation, the terminal can determine whether to select or reselect a cell based on the measurement results at the first target frequency or the second target frequency, according to the second information.

[0253] That is, the measurement results used in cell selection or reselection are the measurement results on the first target frequency (e.g., the first frequency point) or the measurement results on the second target frequency (e.g., the second frequency point).

[0254] For example, cell selection may be performed only if the measurement results on both the first target frequency (e.g., the first frequency point) and the second target frequency (e.g., the second frequency point) meet the cell selection criteria, or cell reselection may be performed only if the measurement results on both the first target frequency (e.g., the first frequency point) and the second target frequency (e.g., the second frequency point) meet the cell reselection criteria. Furthermore, the terminal camps on a cell on either the first target frequency or the second target frequency.

[0255] Alternatively, cell selection is performed if either the measurement results on the first target frequency (e.g., the first frequency point) or the second target frequency (e.g., the second frequency point) meet the cell selection criteria; or cell reselection is performed if either the measurement results on the first target frequency (e.g., the first frequency point) or the second target frequency (e.g., the second frequency point) meet the cell reselection criteria. The terminal then camps on a cell on a frequency point that meets the cell selection or reselection criteria.

[0281] 1) Enable or activate the first method, or disable or deactivate the first method;

[0282] 2) Enable or activate the second method, or disable or deactivate the second method.

[0283] For example, the third information may be carried by at least one of the following: broadcast message (such as system information), paging message, advance indication message, or RRC-specific message. The RRC-specific message may be an RRC reconfiguration message, an RRC configuration message, an RRC release message, or an RRC suspend message.

[0284] In another embodiment of this application, the terminal determines at least one of the following: enabling or activating the first mode, or disabling or deactivating the first mode; enabling or activating the second mode, or disabling or deactivating the second mode, including:

[0293] 4) Measure the first target frequency or the cell on the first target frequency using the main receiver.

[0294] In scenarios where LR and MR are deployed on different frequency points, this embodiment can achieve cross-frequency deployment by measuring the frequency point corresponding to LR through MR. This enables the terminal to use LP-WUS, LP-WUR, LP-SS, or LR in more scenarios and at more times to achieve power saving.

Specifically, when performing cell selection or reselection according to the first method, the terminal can prioritize selecting or reselecting to a first target cell related to the first characteristic or the first configuration, instead of selecting or reselecting to a second target cell. This strategy allows the terminal to effectively utilize LP-WUS, LP-WUR, LP-SS, or LR in more scenarios and for more time, thereby significantly improving power saving gains.

This strategy allows the terminal to effectively utilize LP-WUS, LP-WUR, LP-SS, or LR in more scenarios and for more time, thereby significantly improving power saving gains.
