[0037] Embodiments of the present disclosure provide a communication method, a terminal, a network device, a system, and a storage medium.

[0038] In a first aspect, an embodiment of the present disclosure provides a communication method, executed by a terminal, the method comprising:

[0039] First indication information sent by a network device is received, where the first indication information is used to indicate whether the terminal uses a low power receiver LR to perform RRM measurement of a neighboring cell.

[0040] In the above embodiment, the terminal receives the first indication information to learn whether the network device configures the terminal to use the LR to perform RRM measurements of neighboring cells, so that the terminal can reasonably use the LR to perform allowed measurements based on the configuration of the network device, thereby saving energy consumption of the terminal.

[0041] In conjunction with the embodiments of the first aspect, in some embodiments, the method further includes:

[0042] receiving second indication information sent by the network device, where the second indication information is used to indicate a reference signal used for RRM measurement; or,

[0043] The reference signal used for RRM measurement is defined by the protocol;

[0044] The reference signal includes at least one of the following: a low power synchronization signal (LP-SS), a primary synchronization signal (PSS), and a secondary synchronization signal (SSS).

[0045] In the above embodiment, the terminal can obtain the reference signal used when performing neighbor cell measurement using LR through the instruction of the network device or protocol definition, so that the terminal can measure the reference signal at an appropriate time.

[0046] In combination with the embodiments of the first aspect, in some embodiments, the LR is an OOK LR that supports processing binary on-off keying (OOK) signals or an OFDM LR that supports processing orthogonal frequency division multiplexing (OFDM) modulated signals.

[0047] In the above embodiment, terminals of different LR types have different signal processing capabilities, and measurement is performed based on the corresponding reference signal based on the LR capability of the terminal.

[0048] In conjunction with the embodiments of the first aspect, in some embodiments, the first indication information is used to indicate at least one of the following information:

[0049] The OOK LR terminal performs LP-SS-based RRM measurements;

[0050] The OFDM LR terminal performs LP-SS-based RRM measurements;

[0052] In the above embodiment, the first indication information may indicate measurement modes of different LR terminals respectively, and the terminal of the corresponding LR may perform corresponding measurements based on its own LR.

[0053] In combination with the embodiments of the first aspect, in some embodiments, the frequency supported by OFDM LR includes the frequency where the PSS is located or the frequency where the SSS is located.

[0054] In the above embodiment, the PSS or SSS may be on multiple frequencies defined by the protocol, and the frequencies supported by the terminal OFDM LR include the frequencies where the PSS or SSS is located, so that the PSS or SSS can be detected for performing measurements based on the PSS or SSS.

[0055] In combination with the embodiments of the first aspect, in some embodiments, when the terminal is in a radio resource control (RRC) idle state or an inactive state, the first indication information is used to instruct the OOK LR terminal to perform LP-SS-based RRM measurement or the OFDM LR terminal to perform LP-SS-based RRM measurement.

[0056] In the above embodiment, the network device instructs the terminal in the RRC idle state or inactive state to perform LP-SS-based measurement through the LR through the first indication information; for example, if the terminal in the RRC connected state (connected) performs LP-SS-based measurement, the terminal may perform frequency domain switching between its own activated bandwidth part (Bandwidth Part, BWP) and the frequency of the LP-SS. For details, please refer to the description of the following embodiment.

[0062] The RRM measurement of the neighboring cell is performed through the primary receiver MR, wherein the first indication information indicates that the terminal cannot use the LR to perform the RRM measurement.

[0063] In the above embodiment, when the first instruction information instructs the terminal to use the LR to perform measurement, the terminal may perform measurement through the LR to improve the energy saving effect of the terminal.

[0064] In conjunction with the embodiments of the first aspect, in some embodiments, the method further includes:

[0065] Receive fourth indication information sent by the network device, where the fourth indication information is used to indicate whether the terminal uses the MR to perform the RRM measurement of the neighboring cell when using the LR to perform the RRM measurement of the neighboring cell.

The entities may be connected or disconnected, and the connection may be in any manner, which may be direct or indirect, and may be wired or wireless.

[0161] The embodiments of the present disclosure 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 (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (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 utilizing other communication processing methods, and next-generation systems based on and extending these. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0162] In the disclosed embodiment, if terminal 101 does not detect the corresponding LP WUS or the detected LP WUS indicates not to wake up the MR, terminal 101 can maintain the MR in a sleep state, such as an ultra-deep sleep state, thereby significantly reducing the MR's power consumption. Furthermore, the LP WUS has extremely low power consumption, which can achieve greater power savings.

[0163] In the disclosed embodiment, to properly detect the LP-WUS, terminal 101 needs to obtain the time and frequency location of the LP-WUS transmission by network device 102. Terminal 101 can achieve time and frequency synchronization by detecting a synchronization signal. Optionally, the synchronization signal can be, for example, a Synchronization Signal Block (SSB) or an LP-SS.

[0164] The embodiments of the present disclosure provide a method for performing RRM measurement of neighboring cells using an LR.

[0165] Figure 2a is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2a, the embodiment of the present disclosure relates to a communication method, the method comprising:

[0166] Step S2101 : Terminal 101 sends capability information to network device 102 .

[0167] Optionally, the capability information is used to indicate the capability of the terminal 101 to use the LR to perform neighbor cell RRM measurements.

[0168] Optionally, the terminal 101 may synchronously report the capability of using the LR to perform neighboring cell RRM measurements when reporting other terminal capabilities, or report the capability of using the LR to perform neighboring cell RRM measurements separately.

[0169] Optionally, the terminal 101 may proactively report the above capabilities, or report based on instructions from the network device 102 .

[0170] Optionally, the terminal 101 that reports the capability information is in an RRC connected state.

[0171] In some embodiments, the capability includes at least one of the following:

[0172] First capability to perform LP-SS based neighbor cell RRM measurements via OOK LR;

[0173] A second capability to perform LP-SS based neighbor cell RRM measurements via OFDM LR;

[0174] The third capability is to perform neighbor cell RRM measurements based on PSS or SSS through OFDM LR.

[0175] Optionally, LR includes at least two types: OOK LR and OFDM LR. OOK LR supports signal energy detection, such as envelope detection of OOK symbols carrying LP-WUS. However, OOK LR has relatively poor link performance. OFDM LR supports demodulation of modulated signals, such as detecting the OFDM time-domain or frequency-domain sequence carried by OOK symbols of LP-WUS, thereby improving link performance.

[0176] Optionally, when the frequency of the PSS or SSS is within a frequency band supported by the OFDM LR, the OFDM LR may detect the PSS sequence or the SSS sequence.

[0177] Optionally, in addition to being used for synchronization, the LPSS can also serve as a reference signal for RRM measurements. For OOK LR, the OOK signal in the LPSS time domain can be detected. For OFDM LR, both the LPSS time domain signal and OFDM demodulation can be performed on the information carried in the LPSS frequency domain.

[0178] Optionally, the LPSS is a cell-level common signal. The LPSS configuration or configuration information can be per-cell, meaning each cell can be configured with an LPSS. Alternatively, some cells may be configured with an LPSS, such as a cell configured with an LPSS but its neighboring cells not. The power of the LPSS configured in different cells may vary.

[0179] In some embodiments, step S2101 may be omitted, for example, terminal 101 does not need to report the above capabilities and performs corresponding operations based on the instructions of network device 102. When the operation instructed by network device 102 exceeds the capabilities of terminal 101, terminal 101 may ignore the relevant instructions.

[0180] In some embodiments, the network device 102 may receive capability information of the terminal 101 to learn the measurement capability of the terminal 101 using LR, so as to configure relevant parameters for performing RRM measurement using LR for the terminal 101 in the RRC connected state.

[0181] Step S2102 , the network device 102 sends first indication information to the terminal 101 .

[0182] Optionally, the first indication information is used to indicate whether the terminal 101 uses LR to perform RRM measurement of neighboring cells.

[0183] In some embodiments, the network device 102 uses higher layer parameters to explicitly configure the terminal 101 whether to use the LR to perform RRM measurements of neighboring cells.

[0184] Optionally, the first indication information is sent via broadcast information or via terminal-specific signaling.

[0185] In one example, for a terminal 101 in an RRC idle state or an RRC inactive state, the network device 102 broadcasts first indication information via system information (SI). For example, a parameter is configured in the SI. When the parameter corresponds to a first parameter value, the terminal 101 is instructed to use the LR to perform RRM measurements of neighboring cells. The terminal 101 may perform step S2105. When the parameter corresponds to a second parameter value, the terminal 101 is instructed not to use the LR to perform RRM measurements of neighboring cells. The terminal 101 may perform step S2106.

[0186] In another example, for the terminal 101 in the RRC connected state, the network device 102 sends the first indication information through UE-specific RRC signaling. For example, a parameter is configured in the UE-specific RRC signaling. When the parameter corresponds to a first parameter value, the terminal 101 is instructed to use the LR to perform RRM measurements of neighboring cells. The terminal 101 can perform step S2105. When the parameter corresponds to a second parameter value, the terminal 101 is instructed not to use the LR to perform RRM measurements of neighboring cells. The terminal 101 can perform step S2106.

[0187] Optionally, when the network device 102 is not configured with the first indication information or the above parameters, it indicates that the terminal 101 cannot use the LR to perform RRM measurement of the neighboring cell, and the terminal 101 can execute step S2106.

[0188] Optionally, the neighboring cell is a same-frequency neighboring cell or a different-frequency neighboring cell of the terminal serving cell.

[0189] In some embodiments, the terminal 101 receives the first indication information.

[0190] Step S2103 , the network device 102 sends second indication information to the terminal 101 .

[0191] Optionally, the second indication information is used to indicate a reference signal used for RRM measurement.

[0192] Optionally, the reference signal includes at least one of the following: LP-SS, PSS, SSS.

[0193] In one example, when a neighboring cell is configured with an LP SS and the LP SS can be measured by terminal 101 in the current cell through LR, network device 102 can configure terminal 101 to perform RRM measurements of the neighboring cell based on the LP SS. If the neighboring cell is not configured with an LP SS, network device 102 cannot configure terminal 101 to perform RRM measurements of the neighboring cell based on the LP SS.

[0194] In this example, if the neighboring cell performs power boosting, or the terminal 101 has an OFDM LR, it can be considered that the LP SS can be measured by the terminal 101 in the current cell through the LR.

[0195] Optionally, the network device 102 may learn about the situation of neighboring cells through an interface between base stations or a network node such as a network control center, so as to perform reasonable configuration.

[0196] Optionally, step S2103 may be omitted. For example, if the reference signal used for RRM measurement is defined by a protocol, step S2103 may be omitted.

[0197] In some embodiments, the first indication information and the second indication information may be sent through the same signaling, such as the first indication information and the second indication information are different parameters in the same signaling; or, the first indication information and the second indication information may be sent separately through different signaling.

[0198] Optionally, the second indication information may be sent via broadcast information or dedicated signaling.

[0199] In some embodiments, there is a large difference in reception performance between OOK LR and OFDM LR. The first indication information may indicate a specific LR, or indicate both LRs separately.

[0200] In one example, the LR is an OOK LR that supports processing OOK signals or an OFDM LR that supports processing OFDM modulated signals. For example, the first indication information is used to instruct terminal 101 of the OFDM LR, or the measurement indicated by the first indication information is performed by terminal 101 of the OFDM LR by default. For terminal 101 of the OOK LR, neighboring cell RRM measurements based on the aforementioned reference signal may be not supported by default.

[0201] In another example, the first indication information is used to indicate at least one of the following information:

[0202] The OOK LR terminal performs LP-SS-based RRM measurements;

[0203] The OFDM LR terminal performs LP-SS-based RRM measurements;

[0204] The OFDM LR terminal performs RRM measurements based on the PSS or SSS.

[0205] In this example, the RRM measurement is an RRM measurement of a neighboring cell, such as a same-frequency neighboring cell or an inter-frequency neighboring cell.

[0206] In this example, network device 102 can provide separate instructions for different LRs and reference signals. For example, if a neighboring cell is configured with LP-SS power boost, and the neighboring cell and the current cell have a large overlapping coverage area in network deployment, and the LP-SS of the neighboring cell can be measured using OOK LR, network device 102 can configure terminal 101 using OOK LR to perform RRM measurements on the neighboring cell.

[0207] In this example, the frequencies supported by OFDM LR include the frequencies where the PSS or SSS resides. The frequencies supported by OFDM LR on terminal 101 may be some frequencies defined by the protocol. Due to the low-cost and low-complexity nature of LR, the supported frequencies may be relatively few. The PSS or SSS can be on many frequencies defined by the protocol. If the frequency of the PSS or SSS of a neighboring cell is not within the frequency range supported by OFDM LR, OFDM LR cannot be used to perform neighboring cell RRM measurements of the PSS or SSS.

[0208] In this example, when terminal 101 is in the RRC idle or inactive state, the first indication information is used to instruct an OOK LR terminal to perform RRM measurements based on the LP SS, or an OFDM LR terminal to perform RRM measurements based on the LP SS. As described in the preceding embodiments, the LP SS is a cell-level common signal. If measurements based on the LP SS are configured for terminal 101 in the RRC connected state, the LP SS may not be on the active BWP of terminal 101 in the connected state, or may not overlap with the active BWP. Therefore, when monitoring, terminal 101 in the connected state needs to switch between the frequencies corresponding to the active BWP and the LP SS, increasing the overhead of terminal 101.

[0209] In some embodiments, the terminal 101 receives the second indication information.

[0210] Step S2104 : The network device 102 sends third indication information to the terminal 101 .

[0211] Optionally, the third indication information is used to indicate cell information of at least one neighboring cell measured by the LR; wherein the cell information includes at least one of the following: a cell identifier, a cell index, and a cell frequency.

[0212] In an example, the network device 102 configures the terminal 101 to use the LR to perform RRM measurement on a neighboring cell of a specific frequency through the third indication information. For example, the neighboring cell of the specific frequency is a cell of a high-priority frequency.

[0213] In some embodiments, the third indication information may be sent separately, or sent through the same signaling as the first indication information and / or the second indication information, or the first indication information, the second indication information and the third indication information may be different parameters in the same signaling.

[0214] Optionally, the third indication information may be sent via broadcast information or dedicated signaling. When sent via broadcast information, the network device 102 may configure a certain type of LR to perform RRM measurements on a certain neighboring cell, for example, configuring a terminal with OFDM LR to perform RRM measurements on one or more neighboring cells.

[0215] In some embodiments, the terminal 101 receives the third indication information.

[0216] Step S2105: Terminal 101 performs RRM measurement of neighboring cells through LR.

[0217] Optionally, when the first indication information instructs the terminal 101 to use LR to perform RRM measurement, the terminal 101 executes step S2105.

[0218] In one example, when the terminal 101 performs measurement through the LR, the MR may be in a sleep state to achieve MR energy saving.

[0219] In another example, during the process of performing measurement through LR, the terminal 101 may perform relaxation measurement through MR. For this example, reference may be made to the implementation of step S2206 in the embodiment of FIG. 2 b , which will not be described in detail here.

[0220] In some embodiments, when the terminal 101 detects that a condition for starting neighbor cell measurement is met, the LR may be used to perform neighbor cell measurement, where using the LR is more energy-efficient than using the MR.

[0221] Optionally, the condition may be that: the terminal 101 performs measurement on the serving cell or the resident cell, and the measurement value is lower than a threshold. For example, when the measurement result of the serving cell of the terminal 101 is lower than a first threshold, the same-frequency neighbor cell measurement is initiated; when the measurement result of the serving cell is lower than a second threshold, the inter-frequency neighbor cell measurement is initiated.

[0222] Optionally, for cells with high priority frequencies, the terminal 101 may always enable measurement of cells with high priority frequencies without any judgment conditions.

[0223] Step S2106: Terminal 101 performs RRM measurement of neighboring cells through MR.

[0224] Optionally, when the first indication information indicates that the terminal 101 cannot use the LR to perform RRM measurement, the terminal 101 executes step S2106.

[0225] In some embodiments, when the terminal 101 detects that the condition for starting neighbor cell measurement is met, it is necessary to start MR to measure the neighbor cell. The measurement conditions can be found in the description of the embodiment in step S2105 and will not be repeated here.

[0226] Optionally, steps S2106 and S2105 are parallel steps, and terminal 101 can execute one of them.

[0237] In some embodiments, step S2101 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0238] In some embodiments, the order of steps S2102 to S2104 can be exchanged or performed synchronously, such as the network device 102 sends the first indication information, the second indication information, and the third indication information through one signaling.

[0239] In some embodiments, steps S2105 and S2106 are performed in parallel, and the terminal 101 executes one of them based on the first indication information.

[0240] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2 a .

[0241] Figure 2b is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2b, the embodiment of the present disclosure relates to a communication method, the method comprising:

[0242] Step S2201 : Terminal 101 sends capability information to network device 102 .

[0243] In some embodiments, the implementation of step S2201 can refer to the optional implementation of step S2101 and will not be repeated here.

[0244] Step S2202 , the network device 102 sends first indication information to the terminal 101 .

[0245] In some embodiments, the implementation of step S2202 can refer to the optional implementation of step S2102 and will not be repeated here.

[0246] Step S2203 , the network device 102 sends second indication information to the terminal 101 .

[0247] In some embodiments, the implementation of step S2203 can refer to the optional implementation of step S2103 and will not be repeated here.

[0248] Step S2204 : The network device 102 sends third indication information to the terminal 101 .

[0249] In some embodiments, the implementation of step S2204 can refer to the optional implementation of step S2104 and will not be repeated here.

[0250] Step S2205 : The network device 102 sends fourth indication information to the terminal 101 .

[0251] Optionally, the fourth indication information is used to indicate whether the terminal uses the MR to perform the RRM measurement of the neighboring cell when using the LR to perform the RRM measurement of the neighboring cell.

[0252] In some embodiments, the fourth indication information may be sent separately, or sent through the same signaling as at least one of the first indication information, the second indication information, and the third indication information.

[0253] Optionally, the fourth indication information may be sent via broadcast information or via terminal-specific signaling.

[0254] In some embodiments, the measurement period of the neighbor cell RRM measurement performed by the MR is greater than the measurement period of the neighbor cell RRM measurement performed by the LR. That is, during the process of the LR performing the neighbor cell measurement, the neighbor cell measurement performed by the MR is a relaxed measurement.

[0255] For example, the measurement period during which the MR performs RRM measurements is N times the measurement period during which the LR performs RRM measurements. Alternatively, the measurement period during which the MR performs RRM measurements when the LR performs RRM measurements is N times the measurement period during which the MR performs RRM measurements normally without performing RRM measurements. N is greater than 1. Optionally, N is configured by the network device 102 or defined by a protocol.

[0256] In some embodiments, when the fourth indication information instructs the terminal 101 to use the MR to perform relaxed neighbor cell RRM measurement during the LR measurement process, the terminal 101 may perform step S2206 or step S2207.

[0257] Step S2206: The terminal 101 performs RRM measurement of the neighboring cell through the MR during the period when the terminal 101 performs RRM measurement of the neighboring cell through the LR.

[0258] Optionally, the measurement period of the MR performing RRM measurement still satisfies the implementation in step S2205. For example, the measurement period of the terminal 101 performing RRM measurement using the MR is N times the measurement period of the LR performing RRM measurement, thereby improving measurement accuracy while still maintaining the energy saving effect of the MR.

[0259] Optionally, the neighboring cell targeted by the above measurement may be an intra-frequency neighboring cell or an inter-frequency neighboring cell.

[0260] In step S2207, when the measurement result of the RRM measurement of the neighboring cell performed by the LR is lower than the threshold, the terminal 101 performs the RRM measurement of the neighboring cell through the MR.

[0261] Optionally, the measurement result is, for example, 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 indication (RSSI).

[0262] Optionally, the measurement accuracy of MR is higher than that of LR, especially in a low signal-to-noise ratio scenario, so the terminal 101 may use the measurement result of MR to correct the measurement result of LR to improve the accuracy of the measurement result.

[0263] The method involved in the embodiment of the present disclosure may include at least one of steps S2201 to S2207, such as the method including step S2202.

[0264] In some embodiments, step S2201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0265] In some embodiments, the order of steps S2202 to S2205 can be exchanged or executed synchronously, such as the network device 102 sends the first indication information, the second indication information, the third indication information and the fourth indication information through one signaling, or the network device 102 sends the four indication information respectively through different signaling.

[0266] In some embodiments, steps S2206 and S2207 are performed in parallel, and the terminal 101 may execute one of them.

[0267] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2 b .

[0302] In some embodiments, the LR is an OOK LR supporting processing of binary on-off keying (OOK) signals or an OFDM LR supporting processing of orthogonal frequency division multiplexing (OFDM) modulated signals.

[0381] The method of the embodiment of the present disclosure can solve the problem of how to use LP WUR to perform neighboring cell RRM measurement. To facilitate understanding of the embodiment of the present disclosure, some examples are listed below:

[0382] Example 1:

[0383] The base station configures whether to use the LR to perform the neighboring cell RRM measurement based on the first signal, for example, by using a high-layer parameter explicit configuration.

[0384] Optionally, if the base station is not configured to use the first signal for neighboring cell RRM measurements, then when the UE detects that the conditions for enabling neighboring cell measurements are met, it is necessary to enable MR to perform neighboring cell measurements. If the first signal is configured for neighboring cell measurements, then when the UE detects that the conditions for enabling neighboring cell measurements are met, it can use LR to perform neighboring cell measurements. Using LR is more energy-efficient than using MR.

[0385] Optionally, the first signal may be LP-SS, PSS or SSS.

[0386] Optionally, if the neighboring cell has LP-SS and can be measured by the LR of the UE in this cell, the base station can be configured to use LR for LP-SS-based neighboring cell measurements. If the neighboring cell does not have LP-SS, LP-SS cannot be configured for neighboring cell RRM measurements.

[0387] Optionally, the neighbor cell measurement may be an intra-frequency neighbor cell RRM measurement or an inter-frequency neighbor cell RMM measurement.

[0388] Optionally, considering the large difference in reception performance between OOK LR and OFDM LR, the measurement is performed by the OFDM LR terminal by default. For the OOK LR terminal, it is defaulted that it does not support neighbor cell measurement based on the first signal.

[0389] Optionally, broadcast information configuration (for RRC idle or inactive UE) or UE specific signaling configuration (for RRC connected UE) can be used.

[0390] Example 2:

[0391] Based on Example 1, the base station can configure whether to perform the following RRM measurements:

[0392] a) Use OOK LR for LP-SS-based neighbor cell measurement (same-frequency / inter-frequency neighbor cell measurement), where:

[0393] If a neighboring cell has LP-SS power boosting and the neighboring cell overlaps significantly with the local cell in network deployment, the neighboring cell's LP-SS can be measured even with OOK LR. In this case, OOK LR can be used for RRM measurements of the neighboring cell. The base station can monitor the neighboring cell's status through inter-base station interfaces or network nodes such as the network control center, allowing for appropriate configuration.

[0394] b) Use OFDM LR to perform LP-SS-based neighbor cell measurements (same-frequency or different-frequency neighbor cell measurements);

[0395] c) Use OFDM LR to perform neighboring cell RRM measurements based on PSS or SSS (same-frequency or different-frequency neighboring cell measurements), where:

[0396] The frequencies supported by OFDM LR may be those defined by the protocol. Given LR's low cost and low complexity, the supported frequencies may be relatively limited. However, the PSS or SSS can be located on many frequencies in existing protocols. It is possible that the PSS / SSS of a neighboring cell may not be located in the frequency range supported by OFDM LR. In this case, OFDM LR cannot be used to perform neighboring cell RRM measurements of the PSS or SSS.

[0397] Optionally, a) to c) are applicable to RRC idle, inactive, or RRC connected states, wherein a) and b) are preferably applied to RRC idle or inactive states.

[0398] Example 3:

[0399] Based on Example 1, the base station may further configure whether to start the MR to perform relaxed neighboring cell RRM measurement while using the LR to perform neighboring cell measurement based on the first signal.

[0400] a) The MR performs relaxed neighboring cell RRM measurement, which can be performed by the MR with a larger measurement period (for example, N times the LR measurement LP-SS period), and can be further divided into intra-frequency neighboring cell measurement and inter-frequency neighboring cell measurement. For example:

[0401] i. While the LR is performing neighbor cell measurements, the MR performs relaxed measurements;

[0402] ii. When the LR measurement result is lower than a certain threshold, MR performs a relaxed measurement.

[0403] Optionally, the measurement accuracy of MR is higher than that of LR (especially in the case of low signal-to-noise ratio), and the measurement result of MR can be used to make some corrections to the measurement result of LR.

[0404] Example 4:

[0405] Based on Example 1, the base station configures the terminal whether to use LR to perform RRM measurement on one or more neighboring cells (or neighboring cells of a specific frequency), for example, the neighboring cell is a cell of a high-priority frequency.

[0406] Optionally, the configuration may be UE-specific or broadcast. In the case of broadcast, a certain type of LR may be configured to perform RRM measurements on a certain neighboring cell. For example, an OFDM LR may be configured to perform RRM measurements on one or more neighboring cells.

[0407] Example 5:

[0408] Based on Example 1, define UE capabilities: UE capabilities for using LR to perform neighboring cell RRM measurements. This includes:

[0409] The ability to use OOK LR for LP-SS-based neighbor cell measurements;

[0410] Ability to use OFDM LR to perform LP-SS-based neighbor cell measurements;

[0411] The ability to use OFDM LR to perform neighboring cell RRM measurements based on PSS or SSS.

[0412] Optionally, the neighbor cell measurement in the capability includes same-frequency neighbor cell measurement or different-frequency neighbor cell measurement.

[0413] Optionally, the UE may also report the capability and the type of its own LR to the base station, so that the base station can configure relevant parameters for the UE to perform RRM measurement using the LR in the RRC connected state.
