Description

Cell selection or reselection methods, information processing methods and devices

[0001] This disclosure claims priority to Chinese Patent Application No. 202410970248.4, filed with the Chinese Patent Office on July 19, 2024, entitled “Method for Cell Selection or Reselection, Information Processing Method and Apparatus”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a cell selection or reselection method, information processing method and apparatus. Background Technology

[0003] Even after considering terminal power-saving technologies in related fields, the terminal still has relatively high power consumption. Therefore, a low-power receiver with lower complexity is introduced to further reduce terminal power consumption. When the terminal operates in the Radio Resource Control (RRC) idle state or RRC inactive state using a low-power receiver, if the main receiver is still used to perform cell selection and reselection measurements, there will be problems of high latency and power consumption, and the energy-saving gain brought by introducing a low-power receiver cannot be maximized. However, if the measurement results are directly based on the low-power receiver, the reliability of Radio Resource Management (RRM) measurements and mobility quality may not be guaranteed. It can be seen that the related technical solutions cannot maximize the terminal's energy-saving gain while ensuring the accuracy of RRM measurement results and mobility quality. Summary of the Invention

[0099] The above-disclosed technical solution has at least the following beneficial effects:

[0100] In this embodiment, if the sum of the second difference obtained by the terminal based on the RRM measurement results of the main receiver and the RRM measurement results of the low-power receiver does not meet the cell selection conditions, and if the second difference is less than the first difference configured by the network-side equipment, then cell selection and / or reselection operations are performed using the low-power receiver. In this scheme, the sum of the second difference and the RRM measurement results of the low-power receiver is relatively close to the RRM measurement results of the main receiver. Since existing cell selection conditions are configured based on the RRM measurement results of the main receiver, determining whether cell selection conditions are met based on the sum of the second difference and the RRM measurement results of the low-power receiver has high reliability.

[0109] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0110] The terms “first,” “second,” etc., used in this disclosure and in the claims are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this disclosure described herein may be implemented, for example, in sequences other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0111] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship. In this disclosure, the term "multiple" refers to two or more objects, and other quantifiers are similar.

[0112] In this disclosure, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0113] Figure 1 shows a block diagram of a wireless communication system applicable to an embodiment of this disclosure. The wireless communication system includes a terminal device 11 and a network-side device (or network device) 12. The terminal device 11 can also be referred to as a terminal or user equipment (UE). It should be noted that the specific type of terminal 11 is not limited in this embodiment. The network-side device 12 can be a base station or a core network. It should be noted that this embodiment only uses a base station in an NR system as an example, but the specific type of base station is not limited.

[0114] In related technologies, the receiver of the terminal has a high implementation complexity. Currently, various terminal power-saving technologies have been considered, such as discontinuous reception (DRX), in which the terminal periodically turns the receiver on / off through discontinuous reception to achieve the purpose of power saving; and Paging Early Indication (PEI) technology, in which the terminal stops using the receiver to perform physical downlink control channel (PDCCH) or paging detection, and when the terminal needs to receive PDCCH or paging, the network indicates it through other signals to achieve the purpose of power saving.

[0115] After introducing a low-power receiver, the terminal can achieve further energy savings by only turning on the low-power receiver. However, when the terminal needs to perform cell selection / reselection measurements, it needs to turn on the main receiver again, which introduces latency and increased power consumption. Currently, the conditions for turning the low-power receiver on / off and the conditions for turning the main receiver on / off are configured by the base station. Since the base station does not have information about the performance of the terminal's low-power receiver, the conditions configured by the base station cannot maximize the terminal's energy-saving gains.

[0116] In addition, the conditions for turning the low-power receiver on / off, as well as the cooperation method and conditions between the low-power receiver and the main receiver, have a crucial impact on the energy-saving gain that the terminal can obtain. Currently, the scheme in which the base station configures the conditions on its own without any reference information cannot maximize the energy-saving gain of the terminal.

[0117] As shown in Figure 2, this embodiment of the present disclosure provides a cell selection or reselection method, executed by a terminal, the method including:

[0118] Step 201: Obtain first indication information, the first indication information is used to indicate a first difference in the network-side device configuration, the first difference is the maximum value of the difference between the Radio Resource Management (RRM) measurement result of the terminal's main receiver and the RRM measurement result of the terminal's low-power receiver.

[0119] The power consumption of the main receiver is greater than that of the low-power receiver.

[0120] As one implementation method, obtaining the first indication information includes obtaining the first indication information through system messages.

[0121] Step 202: If the sum of the RRM measurement result of the low-power receiver and the second difference does not meet the cell selection condition, and if the second difference is less than or equal to the first difference, then the low-power receiver is used to perform a cell selection or reselection operation.

[0122] The second difference is determined by the terminal based on the difference between the RRM measurement result of the primary receiver and the RRM measurement result of the low-power receiver. In some embodiments, the RRM measurement result is obtained by performing RRM measurements on the serving cell.

[0123] The cell selection criteria mentioned above can be cell selection S-conditions. The sum of the RRM measurement result of the low-power receiver and the second difference is close to the RRM measurement result of the first master receiver. Here, reusing the existing cell selection criteria and determining whether the cell selection criteria are met based on the sum of the RRM measurement result of the low-power receiver and the second difference has high reliability. If the second difference is less than the first difference, it indicates that the low-power receiver has high reliability. Therefore, in this case, performing cell selection and / or reselection operations based on the RRM measurement result of the low-power receiver has high reliability.

[0124] In some embodiments, performing cell selection or reselection operations using the low-power receiver includes performing candidate cell ranking and reselection operations based on RRM measurements from the low-power receiver.

[0125] In some embodiments of this disclosure, when both the main receiver and the low-power receiver are turned on, the terminal performs at least one RRM measurement based on the main receiver and the low-power receiver respectively. Based on the at least one RRM measurement of the main receiver, the RRM measurement result of the main receiver is obtained, and based on at least one RRM measurement of the low-power receiver, the RRM measurement of the low-power receiver is obtained. The second difference is obtained based on the difference between the two RRM measurement results, or the second difference is updated.

[0126] In some embodiments of this disclosure, after obtaining the difference between the RRM measurement result of the main receiver and the RRM measurement result of the low-power receiver, the second difference can be obtained by summing the difference with a preset offset value, or by averaging the multiple differences after obtaining multiple differences. The preset offset value can be a positive number, a negative number, or zero.

[0127] In some embodiments, the RRM measurement results are obtained based on at least one of the following:

[0128] Primary Synchronization Signal (PSS) or Secondary Synchronization Signal (SSS);

[0129] Low Power Synchronization Signal (LP-SS);

[0130] Channel State Information Reference Signal (CSI-RS).

[0131] In the above scheme, if the sum of the second difference obtained by the terminal based on the RRM measurement results of the main receiver and the RRM measurement results of the low-power receiver does not meet the cell selection conditions, and if the second difference is less than the first difference configured by the network-side equipment, then the low-power receiver is used to perform cell selection or reselection. In this scheme, the sum of the second difference and the RRM measurement results of the low-power receiver is relatively close to the RRM measurement results of the main receiver. Since the existing cell selection conditions are configured based on the RRM measurement results of the main receiver, determining whether the cell selection conditions are met based on the sum of the second difference and the RRM measurement results of the low-power receiver has high reliability. Furthermore, if the cell selection conditions are not met, and the second difference is less than the first difference, it indicates that the low-power receiver has high reliability. In this case, cell selection and / or reselection can be performed based on the RRM measurement results of the low-power receiver. Because the receiving power consumption of the low-power receiver is less than that of the main receiver, the energy-saving gain of the terminal can be maximized while ensuring the accuracy of the RRM measurement results and mobility quality.

[0132] In some embodiments, the method of this disclosure further includes:

[0133] If the sum of the RRM measurement result of the low-power receiver and the second difference does not meet the cell selection criteria, and if the second difference is greater than the first difference, then the main receiver is used to perform RRM measurement on the serving cell to obtain the target RRM measurement result.

[0134] If the target RRM measurement results do not meet the cell selection criteria, the main receiver is used to perform cell selection or reselection operations.

[0135] If the target RRM measurement result meets the cell selection criteria, the master receiver is used to fall back to the target state, which is the state of the master receiver before performing RRM measurement on the serving cell.

[0136] In some embodiments, the target state includes a closed state and a relaxed RRM measurement state.

[0137] Here, if the sum of the RRM measurement result of the low-power receiver and the second difference does not meet the cell selection condition, and the second difference is greater than the first difference, it indicates that the performance of the low-power receiver is not very high. In this case, the main receiver performs RRM measurement on the serving cell again to verify whether the cell selection condition is met. If the RRM measurement result of the main receiver meets the cell selection condition, the terminal continues to camp on the current cell, and the main receiver can return to the state before performing RRM measurement on the serving cell. For example, if the main receiver, which was previously in the off state, performed RRM measurement on the serving cell, the main receiver can be turned off again. This avoids the problem that the main receiver is always in the measurement state after being turned on due to the low performance of the low-power receiver, which is not conducive to energy saving.

[0138] In some embodiments, the method of this disclosure further includes:

[0139] Send the second difference, which is used by the network-side device to configure the first difference.

[0140] In this embodiment of the disclosure, the terminal reports a second difference so that the network-side device can configure or update the first difference by referring to the second difference.

[0141] Of course, in this embodiment of the disclosure, the network-side device may also configure the first difference in other ways, and this embodiment of the disclosure does not specifically limit this.

[0142] In some embodiments, the method of this disclosure further includes:

[0143] Obtain second indication information, the second indication information being used to indicate at least one of the following: the power-on condition of the main receiver; the power-off condition of the main receiver; the power-on condition of the low-power receiver; the power-off condition of the low-power receiver;

[0144] Based on the second instruction information, control the main receiver to turn on or off, and / or control the low-power receiver to turn on or off.

[0145] In some embodiments, obtaining the second indication information includes obtaining the second indication information through a system message.

[0146] In some embodiments, the terminal reports the performance information of the low-power receiver so that the network-side device can configure the second indication information based on the performance information of the low-power receiver, thereby ensuring the rationality of the configured conditions.

[0147] The aforementioned second instruction information enables flexible configuration of the on / off conditions of the main receiver and the low-power receiver, as well as the cooperation conditions between the main receiver and the low-power receiver, to further ensure the terminal's energy-saving gain.

[0148] In some embodiments, the activation conditions of the low-power receiver include at least one of the following:

[0149] The RRM measurement result of the main receiver is greater than or equal to the first threshold.

[0150] The shutdown condition of the low-power receiver includes the RRM measurement result of the low-power receiver being less than or equal to a second threshold, or the main receiver being in the on state and the RRM measurement result of the main receiver being less than or equal to a first threshold, wherein the second threshold is less than or equal to the first threshold.

[0151] The conditions for turning on the main receiver include the RRM measurement result of the low-power receiver being less than a third threshold.

[0152] The shutdown conditions of the main receiver include the low-power receiver being in the on state and the RRM measurement result of the low-power receiver being greater than or equal to the third threshold.

[0153] The first threshold, the second threshold, or the third threshold are configured by the network-side device or agreed upon by the protocol.

[0154] In this embodiment of the disclosure, when the RRM measurement result of the main receiver is greater than or equal to a first threshold, the low-power receiver is turned on. The low-power receiver monitors the low-power wake-up signal (LP-WUS) and / or performs RRM measurement. The main receiver can perform normal RRM measurement, relaxed RRM measurement, or be turned off.

[0155] In some embodiments of this disclosure, the measurement period of the relaxed RRM measurement is longer than that of the normal RRM measurement, the number of cells or carriers to be measured in the relaxed RRM measurement is less than that in the normal RRM measurement, and / or the number of samples in the relaxed RRM measurement is less than that in the normal RRM measurement.

[0156] In this embodiment of the disclosure, if the RRM measurement result of the low-power receiver is less than or equal to a second threshold, or if the RRM measurement result of the main receiver is less than or equal to a first threshold, the low-power receiver is turned off, and the main receiver performs normal RRM measurement.

[0157] If the RRM measurement result of the low-power receiver is less than the third threshold, the main receiver is turned on and performs a relaxed RRM measurement or a normal RRM measurement; if the RRM measurement result of the low-power receiver is greater than or equal to the third threshold, the main receiver is turned off.

[0158] In some embodiments, the second threshold is determined based on the difference between the first threshold and the first offset, wherein the first offset is greater than or equal to 0; for example, the second threshold is equal to the first threshold minus the first offset.

[0159] Alternatively, the third threshold is determined based on the sum of the first threshold and the second offset, where the second offset is greater than or equal to 0. The third threshold is greater than or equal to the first threshold.

[0160] It should be noted that, in the embodiments of this disclosure, the relaxed RRM measurement performed by the terminal using the main receiver can be a co-frequency measurement, inter-frequency measurement, and / or inter-system measurement of the serving cell and / or neighboring cells for purposes such as cell selection, cell reselection, and / or handover.

[0161] In some embodiments, the low-power receiver includes at least one of the following:

[0162] Type I receiver;

[0163] Type II receiver;

[0164] The first type of receiver is used to receive low power synchronization signal (LP-SS), and the second type of receiver is used to receive primary synchronization signal (PSS) and / or secondary synchronization signal (SSS).

[0165] In this embodiment, the network-side device can independently configure a first offset, a second offset, a second threshold, and / or a third threshold for two types of low-power receivers. That is, the first and second offsets received by the first and second types of receivers can be the same or different, and the second and third thresholds can be the same or different. The terminal calculates the corresponding conditions using the offsets or thresholds and performs the corresponding receiver management operations described above when the conditions are met.

[0166] In addition, when the first offset and the second threshold, or both the second offset and the third threshold are not configured, the terminal defaults to the first offset or the second offset being zero, and the second threshold or the third threshold being equal to the first threshold.

[0167] In some embodiments, the method of this disclosure further includes:

[0168] When the terminal is in Radio Resource Control (RRC) connected state, ignore the on and / or off conditions of the low-power receiver mentioned in the second indication information, use the main receiver to perform RRM measurement, use the low-power receiver to monitor the low-power wake-up signal LP-WUS, and determine whether to use the main receiver to receive the physical downlink control channel PDCCH based on the monitored LP-WUS.

[0169] In this embodiment of the disclosure, while the terminal controls the main receiver to perform RRM measurements, it also controls the main receiver to stop blindly detecting the PDCCH. Here, the main receiver determines whether to receive the PDCCH based on the LP-WUS detected by the low-power receiver, thus avoiding the main receiver from continuously monitoring the PDCCH and effectively reducing the power consumption of the main receiver.

[0170] In addition, the turning on of the receiver in the embodiments of this disclosure can also be described as the activation of the receiver, and the turning off of the receiver can also be described as the deactivation of the receiver.

[0171] In the above scheme, the terminal can use a low-power receiver to complete cell selection and / or reselection measurements when the main receiver is off. The scheme specifies the performance conditions that the low-power receiver must meet to ensure the reliability of RRM measurements and cell selection and reselection. Furthermore, this disclosure proposes that network-side equipment indicate the low-power receiver's on / off conditions and the main receiver's on / off / relaxation conditions via system messages. These conditions can be configured and / or updated by the base station after considering the performance status of the low-power receiver reported by the terminal within the reference cell. This disclosure also specifies the terminal behavior when the corresponding conditions are met, maximizing the terminal's energy-saving gain by introducing a low-power receiver and a low-power reference signal while ensuring the reliability of terminal RRM measurements and mobility quality.

[0172] As shown in Figure 3, this embodiment of the present disclosure also provides an information processing method, executed by a network-side device, the method comprising:

[0173] Step 301: Send first indication information, the first indication information is used to indicate a first difference in the network-side device configuration, the first difference is the maximum value of the difference between the Radio Resource Management (RRM) measurement result of the terminal's main receiver and the RRM measurement result of the terminal's low-power receiver.

[0174] In some embodiments, the receiving power consumption of the primary receiver is greater than that of the low-power receiver. In some embodiments, the RRM measurement result is obtained by performing an RRM measurement on the serving cell.

[0175] In some embodiments, the main receiver is the main receiver of the terminal, and the low-power receiver is the low-power receiver of the terminal.

[0176] As one implementation, sending the first indication information includes sending the first indication information via a system message.

[0177] In this embodiment of the present disclosure, the network-side device sends a first indication message so that if the sum of the second difference obtained by the terminal based on the RRM measurement results of the main receiver and the RRM measurement results of the low-power receiver and the RRM measurement results of the low-power receiver does not meet the cell selection conditions, and if the second difference is less than the first difference configured by the network-side device, then the terminal uses the low-power receiver to perform cell selection and / or reselection operations. In this scheme, the sum of the second difference and the RRM measurement result of the low-power receiver is close to the RRM measurement result of the main receiver. Since the existing cell selection conditions are configured based on the RRM measurement result of the main receiver, determining whether the cell selection conditions are met based on the sum of the second difference and the RRM measurement result of the low-power receiver has high reliability. Furthermore, if the cell selection conditions are not met, and the second difference is less than the first difference, it indicates that the low-power receiver has high reliability. In this case, cell selection and / or reselection can be performed based on the RRM measurement result of the low-power receiver. Since the receiving power consumption of the low-power receiver is less than that of the main receiver, the energy-saving gain of the terminal can be maximized while ensuring the accuracy of the RRM measurement results and mobility quality.

[0178] In some embodiments, the method of this disclosure further includes:

[0179] A second difference is obtained, which is determined by the terminal based on the difference between the RRM measurement result of the main receiver and the RRM measurement result of the low-power receiver;

[0180] Configure the first difference based on the second difference.

[0181] In this embodiment of the disclosure, the terminal reports a second difference so that the network-side device can configure or update the first difference by referring to the second difference.

[0182] Of course, in this embodiment of the disclosure, the network-side device may also configure the first difference in other ways, and this embodiment of the disclosure does not specifically limit this.

[0183] In some embodiments, the method of this disclosure further includes:

[0184] Send a second indication message, the second indication message being used to indicate at least one of the following: the power-on condition of the main receiver; the power-off condition of the main receiver; the power-on condition of the low-power receiver; the power-off condition of the low-power receiver.

[0185] In some embodiments, sending the second indication information includes sending the second indication information via a system message.

[0186] In some embodiments, the terminal reports the performance information of the low-power receiver so that the network-side device can configure the second indication information based on the performance information of the low-power receiver, thereby ensuring the rationality of the configured conditions.

[0187] The aforementioned second instruction information enables flexible configuration of the on / off conditions of the main receiver and the low-power receiver, as well as the cooperation conditions between the main receiver and the low-power receiver, to further ensure the terminal's energy-saving gain.

[0188] In some embodiments, the activation conditions of the low-power receiver include at least one of the following:

[0189] The RRM measurement result of the main receiver is greater than or equal to the first threshold.

[0190] The shutdown condition of the low-power receiver includes the RRM measurement result of the low-power receiver being less than or equal to a second threshold, or the main receiver being in the on state and the RRM measurement result of the main receiver being less than or equal to a first threshold, wherein the second threshold is less than or equal to the first threshold.

[0191] The conditions for turning on the main receiver include the RRM measurement result of the low-power receiver being less than a third threshold.

[0192] The shutdown conditions of the main receiver include the low-power receiver being in the on state and the RRM measurement result of the low-power receiver being greater than or equal to the third threshold.

[0193] The first threshold, the second threshold, or the third threshold are configured by the network-side device or agreed upon by the protocol.

[0194] In this embodiment of the disclosure, when the RRM measurement result of the main receiver is greater than or equal to a first threshold, the low-power receiver is turned on. The low-power receiver monitors the low-power wake-up signal (LP-WUS) and / or performs RRM measurement. The main receiver can perform normal RRM measurement, relaxed RRM measurement, or be turned off.

[0195] In some embodiments of this disclosure, the measurement period of the relaxed RRM measurement is longer than that of the normal RRM measurement, the number of cells or carriers to be measured in the relaxed RRM measurement is less than that in the normal RRM measurement, and / or the number of samples in the relaxed RRM measurement is less than that in the normal RRM measurement.

[0196] In this embodiment of the disclosure, if the RRM measurement result of the low-power receiver is less than or equal to a second threshold, or if the RRM measurement result of the main receiver is less than or equal to a first threshold, the low-power receiver is turned off, and the main receiver performs normal RRM measurement.

[0197] If the RRM measurement result of the low-power receiver is less than the third threshold, the main receiver is turned on and performs a relaxed RRM measurement or a normal RRM measurement; if the RRM measurement result of the low-power receiver is greater than or equal to the third threshold, the main receiver is turned off.

[0198] In some embodiments, the second threshold is determined based on the difference between the first threshold and the first offset, wherein the first offset is greater than or equal to 0.

[0199] Alternatively, the third threshold is determined based on the sum of the first threshold and the second offset, where the second offset is greater than or equal to 0.

[0200] The method of this disclosure will be described in detail below with reference to the embodiments.

[0201] Example 1:

[0202] Assuming there are three terminals in the cell, each in either an RRC idle (RRC_IDLE) or RRC inactive (RRC_INACTIVE) state, and their primary receivers are either off or in deep sleep, the base station configures the first difference in the system message to be 3dB. When the sum of the measurement result based on the low-power receiver and the second difference obtained by the terminal measurement does not satisfy the cell selection condition S, this second difference can be represented by Δ. The corresponding behaviors of each terminal are shown in Table 1.

[0203] Table 1

[0204] For terminals 1 and 3, the terminals can use a low-power receiver to perform cell reselection measurements and perform subsequent sorting and reselection operations based on the measurement results from the low-power receiver. For terminal 2, the terminal needs to activate the master receiver to measure the serving cell and verify whether condition S is met based on the measurement results from the master receiver: if condition S is met, the terminal does not perform cell reselection measurements, and the master receiver can revert to the state before performing the serving cell measurement, which includes a relaxed measurement state and a closed state; if condition S is not met, the terminal uses the master receiver to perform cell reselection measurements and performs subsequent sorting and reselection operations.

[0205] Furthermore, terminal 2 can calculate, update, and store Δ based on the serving cell measurement results of the low-power receiver and the serving cell measurement results of the main receiver. The terminal can update Δ using an averaging or weighted averaging method.

[0206] It should be noted that when the terminal has no delta (Δ), such as when it is accessing the network for the first time, the terminal should use the main receiver to perform cell selection and reselection measurements.

[0207] Example 2:

[0208] Assume there are 15 terminals with low-power receiver capabilities in a cell, and these terminals are in any of the following RRC states, with each terminal having slightly different Δ information. Any of the aforementioned RRC states includes RRC_IDLE, RRC_INACTIVE, or RRC_CONNECTED. Terminal information is shown in Table 2.

[0209] Table 2

[0210] Assuming a terminal in the RRC_CONNECTED state has reported its own Δ, the base station can refer to the first indication information in the configuration system message based on the reported Δ. The base station can use methods such as averaging to perform corresponding configurations based on the reported Δ. The first indication information is an optional configuration; when the base station does not configure the first indication information, its default value can be 0 or it can be specified by the protocol.

[0211] For terminals 1 to 5, when the main receiver is in a powered-off or deep sleep state, and the sum of the low-power receiver and Δ does not satisfy the cell selection S condition, its behavior is the same as in Example 1, and will not be repeated here.

[0212] Example 3:

[0213] In this embodiment, the base station configures conditions in the system message to indicate whether the low-power receiver is turned on / off, and whether the main receiver is turned on / off. The relevant conditions are configured using an offset method. Taking RSRP measurement results based on LP-SS or SSB as an example, the relevant conditions in the system message are shown in Table 3:

[0214] Table 3

[0215] In Table 3 above, -80dBm is the first threshold, 15dB is the first offset, and 20dB is the second offset.

[0216] When the terminal in RRC_IDLE or RRC_INACTIVE mode has a measurement result based on the main receiver that is not less than the low-power receiver enable threshold, the terminal can enable the low-power receiver to perform LP-WUS monitoring and / or RRM measurement. The terminal can choose to disable the main receiver or use the main receiver to perform relaxed RRM measurement.

[0217] When the terminal's measurement result based on the low-power receiver is not less than -65dBm (equal to -80+15) and the main receiver is on, the terminal can turn off the main receiver to obtain the maximum energy-saving gain.

[0218] When the terminal's measurement result based on the low-power receiver is less than -65dBm (equal to -80+15) and the main receiver is off or in deep sleep, the terminal can turn on the main receiver, which can then perform relaxed or normal measurements.

[0219] When the terminal's measurement result based on the low-power receiver is not greater than -95dBm (equal to -80-15), the terminal should turn off the low-power receiver to allow the main receiver to return to normal operation.

[0220] Example 4:

[0221] In this embodiment, the base station configures first indication information in the system message to indicate whether the low-power receiver is turned on or off, as well as conditions for turning the main receiver on or off. The relevant conditions are configured using thresholds, and the relevant conditions in the system message are shown in Table 4.

[0222] Table 4

[0223] In Table 3 above, -80dBm is the first threshold, -95dBm is the second threshold, and -65dBm is the third threshold.

[0224] When the terminal measurement result meets the corresponding threshold, the behavior is the same as in Embodiment 3, and will not be repeated here. In another embodiment, for different conditions, the base station can use a configuration method that combines offset value and threshold, but for the same condition, the base station only uses one configuration method, but the terminal's behavior is independent of the configuration method. That is, when the terminal's measurement result meets the relevant conditions, its behavior is the same as in Embodiment 3.

[0225] Furthermore, when a certain condition is the same as the low-power receiver enable threshold condition (i.e., the first threshold), the base station can choose not to configure the threshold and / or offset for that condition. The terminal should default to the condition being the same as the first threshold, and the terminal behavior is the same as in Embodiment 3. For example, when the low-power receiver disable threshold (i.e., the third threshold) and the low-power receiver enable threshold are the same, the signaling content of the above system message can be as shown in Table 5:

[0226] Table 5

[0227] To maximize the energy-saving gains of the terminal, the base station can refer to the Δ information reported by the terminal when configuring relevant conditions. The way the terminal reports the Δ information and the way the base station uses the Δ information are the same as in Example 2, and will not be repeated here.

[0228] Example 5:

[0229] The difference between Example 5 and Example 3 or Example 4 is that the terminal is in the RRC_CONNECTED state. At this time, when the conditions for the main receiver to be turned off and / or turned on are met, the terminal should ignore the conditions. As shown in Figure 4, the main receiver of the terminal in the RRC_CONNECTED state should not be turned off or in a deep sleep state, and should perform relaxed or normal RRM measurement. However, the main receiver should stop detecting the PDCCH channel, use a low-power receiver to monitor LP-WUS, and decide whether to use the main receiver to receive PDCCH based on the content of LP-WUS.

[0230] In the scheme of this embodiment, the base station instructs the terminal through system messages that it can perform cell selection and / or reselection based on the low-power receiver. When the performance of the terminal's low-power receiver meets the conditions, the terminal can use the low-power receiver to complete cell selection and reselection measurements while the main receiver is in sleep mode, thereby maximizing the terminal's energy-saving gain while ensuring RRM measurement and mobility quality.

[0231] In addition, terminals within the cell can report the performance status of low-power receivers. Based on the reported performance statistics, the base station configures and instructs the activation / deactivation conditions of the low-power receiver and the on / off / relaxation conditions of the main receiver through system messages, ensuring the rationality of the configured conditions. The scheme also specifies the terminal behavior when the corresponding conditions are met, maximizing the terminal energy-saving gain from introducing low-power receivers and low-power reference signals while ensuring network configuration flexibility and terminal RRM measurement and mobility quality.

[0232] As shown in Figure 5, this embodiment of the present disclosure provides a cell selection or reselection device applied to a terminal, including a memory 520, a transceiver 500, and a processor 510.

[0235] If the sum of the RRM measurement result of the low-power receiver and the second difference does not meet the cell selection criteria, and if the second difference is less than or equal to the first difference, then the low-power receiver is used to perform cell selection or reselection operations.

[0236] The second difference is determined by the terminal based on the difference between the RRM measurement results of the main receiver and the RRM measurement results of the low-power receiver.

[0237] In Figure 5, the bus architecture can include any number of interconnected buses and bridges, specifically linking various circuits of one or more processors represented by processor 510 and memory represented by memory 520.

[0242] If the sum of the RRM measurement result of the low-power receiver and the second difference does not meet the cell selection criteria, and if the second difference is greater than the first difference, then the main receiver is used to perform RRM measurement on the serving cell to obtain the target RRM measurement result.

[0243] If the target RRM measurement results do not meet the cell selection criteria, the main receiver is used to perform cell selection or reselection operations.

[0244] If the target RRM measurement result meets the cell selection conditions, the master receiver is controlled to fall back to the target state, which is the state of the master receiver before performing RRM measurement on the serving cell.
