The embodiment of the disclosure provides a method for measuring neighbor cell RRM by utilizing LR.

Fig. 2a is an interactive schematic diagram illustrating a communication method according to an embodiment of the disclosure. As shown in fig. 2a, an embodiment of the present disclosure relates to a communication method, which includes:

In step S2101, the terminal 101 transmits capability information to the network device 102.

Alternatively, the capability information is used to indicate the capability of the terminal 101 to perform neighbor cell RRM measurements using LR.

Alternatively, the terminal 101 may synchronously report the ability to perform the neighbor cell RRM measurement using the LR when reporting the other terminal ability, or separately report the ability to perform the neighbor cell RRM measurement using the LR.

Optionally, the terminal 101 reporting capability information is in RRC connected state.

Optionally, LR includes at least two types: OOK LR and OFDM LR. The OOK LR supports energy detection of signals, such as envelope detection (Envelope Detection) of OOK symbols carrying LP WUS, where the link performance of the OOK LR is relatively poor. OFDM LR supports demodulation of modulated signals, such as detecting OFDM time-domain or frequency-domain sequences carried by OOK symbols of LP-WUS, thereby improving link performance.

Alternatively, the OFDM LR may detect PSS sequences or SSS sequences when the frequency at which the PSS or SSS is located is within the frequency band supported by the OFDM LR.

Alternatively, the LP SS may perform measurements as a reference signal for RRM measurements in addition to being available for synchronization. For OOK LR, OOK signals on the LP SS time domain may be detected; for OFDM LR, either the signal in the LP SS time domain can be detected or the information carried in the LP SS frequency domain can be OFDM demodulated.

Optionally, the LP SS is a cell-level common signal. The configuration or configuration information of the LP SS may be in units of cells (per-cells), i.e., each cell may configure the LP-SS separately. Or some cells are configured with LP SS, e.g., a certain cell is configured with LP SS, but the neighboring cells of that cell are not configured with LP SS. Wherein the power at which different cells are configured with LP SS may be different.

In some embodiments, step S2101 may be omitted, e.g., terminal 101 need not report the above capabilities, and performs the corresponding operations based on the indication of network device 102. The terminal 101 may ignore the relevant indication when the operation indicated by the network device 102 exceeds the capabilities of the terminal 101 itself.

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

In step S2102, the network device 102 transmits first instruction information to the terminal 101.

Alternatively, the first indication information is used to indicate whether the terminal 101 performs RRM measurement of the neighbor cell using LR.

In some embodiments, the network device 102 explicitly configures whether the terminal 101 performs RRM measurements of neighbor cells using LR using higher layer parameters.

Alternatively, the first indication information is sent by broadcast information or by terminal-specific signaling.

In an example, for a terminal 101 in an RRC idle state or an RRC inactive state, the network device 102 transmits the first indication information through a system information (System Information, SI) broadcast. For example, configuring a parameter in SI, which parameter, when corresponding to the first parameter value, instructs the terminal 101 to perform RRM measurement of the neighbor cell using LR, the terminal 101 may perform step S2105; when the parameter corresponds to the second parameter value, indicating that the terminal 101 cannot perform RRM measurement of the neighbor cell using LR, the terminal 101 may perform step S2106.

In another example, for the terminal 101 in the RRC connected state, the network device 102 transmits the first indication information through UE-specific RRC signaling. For example, configuring a parameter in the UE-specific RRC signaling, the parameter corresponding to the first parameter value, instructing the terminal 101 to perform RRM measurement of the neighbor cell using LR, the terminal 101 may perform step S2105; when the parameter corresponds to the second parameter value, indicating that the terminal 101 cannot perform RRM measurement of the neighbor cell using LR, the terminal 101 may perform step S2106.

Alternatively, when the network device 102 is not configured with the first indication information or the above-described parameters, indicating that the terminal 101 cannot perform RRM measurement of the neighbor cell using LR, the terminal 101 may perform step S2106.

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

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

In step S2103, the network apparatus 102 transmits second instruction information to the terminal 101.

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

Optionally, the reference signal comprises at least one of: LP-SS, PSS, SSS.

In an example, network device 102 may configure terminal 101 to perform RRM measurements of a neighbor cell based on an LP SS when the neighbor cell is configured with the LP SS and the LP SS can be measured by terminal 101 under the home cell through LR. If the neighboring cell is not configured with the LP SS, the network device 102 cannot configure the terminal 101 to perform RRM measurement of the neighboring cell based on the LP SS.

In this example, if the neighbor cell performs power boosting (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 under the own cell through the LR.

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

Alternatively, step S2103 may be omitted. The reference signal used for the RRM measurement is defined by the protocol, for example, and step S2103 may be omitted.

In some embodiments, the first indication information and the second indication information may be sent through the same signaling, e.g., 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 are respectively sent through different signaling.

Alternatively, the second indication information may be transmitted through broadcast information or dedicated signaling.

In some embodiments, the reception performance of OOK LR and OFDM LR are widely separated. The first indication information may indicate for one specific LR or indicate for two LR respectively.

In an example, the LR is an OOK LR supporting processing OOK signals or an OFDM LR supporting processing OFDM modulated signals. For example, the first indication information is used to indicate the terminal 101 of the OFDM LR, or the measurement indicated by the first indication information is performed by default by the terminal 101 of the OFDM LR. For the terminal 101 of OOK LR, neighbor cell RRM measurements based on the above-described reference signals may not be supported by default.

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

the terminal of OOK LR performs RRM measurement based on LP-SS;

The terminal of the OFDM LR performs the RRM measurement based on the LP-SS;

the terminal of the OFDM LR performs RRM measurement based on PSS or SSS.

In this example, the RRM measurement is an RRM measurement of a neighbor cell, such as a similar neighbor cell or a different frequency neighbor cell.

In this example, the network device 102 may indicate separately for different LR and reference signals. For example, if the neighboring cell is configured with LP-SS power enhancement, the neighboring cell and the own cell have more overlapping coverage areas on the network deployment, and when the OOK LR can measure the LP-SS of the neighboring cell, the network device 102 may configure the terminal 101 of the OOK LR to perform RRM measurement of the neighboring cell.

In this example, the frequencies supported by the OFDM LR include the frequency at which the PSS is located or the frequency at which the SSS is located. The frequencies supported by the OFDM LR of terminal 101 may be some frequencies defined by the protocol, which may be less due to the low cost low complexity nature of LR. The PSS or SSS may be on many frequencies defined by the protocol, and if the frequency of the PSS or SSS of the neighboring cell is not in a frequency range that can be supported by the OFDM LR, the OFDM LR cannot be used to perform the neighboring cell RRM measurement of the PSS or SSS.

In this example, when the terminal 101 is in the RRC idle state or inactive state, the first indication information is used to instruct the terminal of the OOK LR to perform the LP SS-based RRM measurement or the terminal of the OFDM LR to perform the LP SS-based RRM measurement. In connection with the foregoing description of the embodiments, the LP SS is a cell-level common signal, and if the terminal 101 in the RRC connected state is configured with the measurement based on the LP SS, the LP SS may not be on the active BWP of the terminal 101 in the connected state or have no overlap with the active BWP, and the terminal 101 in the connected state needs to switch between frequencies corresponding to the active BWP and the LP SS when listening, which increases the overhead of the terminal 101.

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

In step S2104, the network apparatus 102 transmits third instruction information to the terminal 101.

Optionally, the third indication information is used to indicate cell information of at least one neighbor cell measured by LR; wherein the cell information includes at least one of: cell identification, cell index and cell frequency point.

In an example, the network device 102 configures the terminal 101 to perform RRM measurement on a neighboring cell of a specific frequency point, for example, a cell of a high priority frequency point, using LR through the third indication information.

In some embodiments, the third indication information may be sent separately or 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.

Alternatively, the third indication information may be transmitted through broadcast information or dedicated signaling. When transmitting via broadcast information, the network device 102 may configure an LR of a certain type to perform RRM measurements on a certain neighbor cell, e.g., configure a terminal with an OFDM LR to perform RRM measurements on a certain neighbor cell or cells.

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

In step S2105, the terminal 101 performs RRM measurement of the neighbor cell by LR.

Alternatively, when the first indication information instructs the terminal 101 to perform RRM measurement using LR, the terminal 101 performs step S2105.

In an example, when the terminal 101 performs measurement through LR, MR may be in a sleep state to achieve MR power saving.

In another example, in the process of performing measurement by the terminal 101 through LR, relaxation measurement may be performed through MR, and this example may refer to the implementation of step S2206 in the embodiment of fig. 2b, which is not described herein.

In some embodiments, when the terminal 101 detects that a condition to turn on neighbor measurement is reached, neighbor measurement may be performed using LR, where using LR is more energy efficient than using MR.

Alternatively, the condition may be: the terminal 101 performs a serving cell or camping cell measurement where the measurement is below a threshold. For example, when the measurement result of the serving cell of the terminal 101 is lower than the first threshold, the same-frequency neighbor cell measurement is started; and when the measurement result of the serving cell is lower than a second threshold, starting the measurement of the inter-frequency neighbor cell.

Alternatively, for the cells of the high priority frequency point, the terminal 101 may always turn on measurement of the cell of the high priority frequency point, without judging the condition.

In step S2106, the terminal 101 performs RRM measurement of the neighbor cell by MR.

Alternatively, when the first indication information indicates that the terminal 101 cannot perform RRM measurement using LR, the terminal 101 performs step S2106.

In some embodiments, when the terminal 101 detects that a condition for starting neighbor cell measurement is reached, it is necessary to start MR for neighbor cell measurement. The measured conditions can be referred to the description of the embodiment in step S2105, and will not be described here.

Alternatively, steps S2106 and S2105 are juxtaposed steps, one of which may be performed by the terminal 101.

In some embodiments, the order between steps S2102-S2104 may be exchanged or performed synchronously, such as the network device 102 sending the first indication information, the second indication information, and the third indication information via a signaling.

In some embodiments, steps S2105 and S2106 are side-by-side, with terminal 101 performing one of them based on the first indication information.

In some embodiments, reference may be made to other alternative implementations described before or after the description corresponding to fig. 2 a.

Fig. 2b is an interactive schematic diagram illustrating a communication method according to an embodiment of the disclosure. As shown in fig. 2b, an embodiment of the present disclosure relates to a communication method, which includes:

In step S2201, the terminal 101 transmits capability information to the network device 102.

In some embodiments, the implementation of step S2201 may refer to an alternative implementation of step S2101, which is not described herein.

In step S2202, the network device 102 transmits first instruction information to the terminal 101.

In some embodiments, the implementation of step S2202 may refer to an alternative implementation of step S2102, which is not described herein.

In step S2203, the network device 102 transmits the second instruction information to the terminal 101.

In some embodiments, the implementation of step S2203 may refer to an alternative implementation of step S2103, which is not described herein.

In step S2204, the network device 102 transmits third instruction information to the terminal 101.

In some embodiments, the implementation of step S2204 may refer to an alternative implementation of step S2104, which is not described herein.

In step S2205, the network device 102 transmits fourth instruction information to the terminal 101.

Optionally, the fourth indication information is used to indicate whether the terminal performs RRM measurement of the neighbor cell using MR in performing RRM measurement of the neighbor cell using LR.

In some embodiments, the fourth indication information may be transmitted alone or through the same signaling as at least one of the first indication information, the second indication information, and the third indication information.

Alternatively, the fourth indication information may be transmitted through broadcast information or through terminal-specific signaling.

In some embodiments, the measurement period for performing RRM measurements of the neighbor cells by the MR is greater than the measurement period for performing RRM measurements of the neighbor cells by the LR. That is, in the process of LR performing neighbor cell measurement, neighbor cell measurement performed using MR is a relaxed measurement.

For example, the measurement period in which the MR performs RRM measurement is N times the measurement period in which the LR performs RRM measurement. Or the measurement period for which the MR performs RRM measurement accompanied when the LR performs RRM measurement is N times the measurement period for which the LR does not perform RRM measurement but the MR normally performs RRM measurement. Wherein N is greater than 1. Optionally, N is configured or protocol defined for the network device 102.

In some embodiments, when the fourth indication information indicates that the terminal 101 performs a relaxed neighbor cell RRM measurement using MR in the course of the LR measurement, the terminal 101 may perform step S2206 or step S2207.

In step S2206, the terminal 101 performs RRM measurement of the neighbor cell by MR during the RRM measurement of the neighbor cell by LR.

Alternatively, the measurement period in which the MR performs RRM measurement still satisfies the embodiment in step S2205. For example, the terminal 101 performs the RRM measurement with the MR with a measurement period N times longer than the measurement period of the RRM measurement with the LR, so that the energy saving effect of the MR can be maintained while improving the measurement accuracy.

Alternatively, the neighbor cell for which the above measurement is performed may be a same-frequency neighbor cell or a different-frequency neighbor cell.

In step S2207, the terminal 101 performs RRM measurement of the neighbor cell by the MR when the measurement result of the LR performing RRM measurement of the neighbor cell is lower than the threshold value.

Alternatively, the measurement result is, for example, at least one of: reference signal received Power (REFERENCE SIGNAL RECEIVED Power, RSRP), reference signal received Quality (REFERENCE SIGNAL RECEIVED Quality, RSRQ), signal-to-noise-and-interference ratio (Signal to Interference plus Noise Ratio, SINR), received signal strength Indication (RECEIVE SIGNAL STRENGTH Indication, RSSI).

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

The method according to the embodiments of the present disclosure may include at least one of step S2201 to step S2207, such as the method includes step S2202.

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

In some embodiments, the sequence between steps S2202-S2205 may be exchanged or performed synchronously, such as the network device 102 sending the first indication information, the second indication information, the third indication information, and the fourth indication information via one signaling, or the network device 102 sending the four indication information via different signaling, respectively.

In some embodiments, steps S2206 and S2207 are side-by-side, one of which may be performed by terminal 101.

In some embodiments, reference may be made to other alternative implementations described before or after the description corresponding to fig. 2 b.

In some embodiments, reference may be made to other alternative implementations described before or after the description corresponding to fig. 4 c.

The method of the embodiment of the disclosure can solve the problem of how to use the LP WUR to make the neighbor cell RRM measurement. To facilitate an understanding of the disclosed embodiments, the following list of examples:

Example one:

Whether the base station configuration uses LR for the first signal based neighbor cell RRM measurement, e.g., using a higher layer parameter display configuration.

Alternatively, if the base station is not configured or not configured to use the first signal to make neighbor RRM measurements, then when the UE detects that a condition for turning on neighbor measurements is reached, it is necessary to start MR to make neighbor measurements. If it is configured that neighbor cell measurements can be made with the first signal, then LR can be used for neighbor cell measurements when the UE detects that conditions for turning on neighbor cell measurements are reached. The use of LR is somewhat more energy efficient than the use of MR.

Alternatively, the first signal may be a LP-SS, PSS, or SSS.

Alternatively, if the neighbor cell has an LP-SS and can be measured by the LR of the UE of the own cell, the base station may configure to use the LR for the LP-SS based neighbor cell measurement and if the neighbor cell does not have an LP-SS, may not configure to use the LP-SS for the neighbor cell RRM measurement.

Alternatively, the neighbor cell measurements may be co-frequency neighbor cell RRM measurements and inter-frequency neighbor cell RMM measurements.

Alternatively, the measurement is performed by default by the terminal of the OFDM LR, considering that there is a large gap in reception performance between OOK LR and OFDM LR. For OOK LR terminals, it is default that it does not support neighbor cell measurements based on the first signal.

Alternatively, a broadcast information configuration (for RRC idle or inactive UEs) or a UE specific signaling configuration (for RRC connected UEs) may be used.

Example two:

based on example one, the base station may respectively configure whether the following RRM measurements can be made:

a) Using OOK LR for LP-SS based neighbor cell measurements (same frequency/different frequency neighbor cell measurements), wherein:

If the neighbor cell has the LP-SS power enhancement, the neighbor cell and the neighbor cell have more overlapping coverage areas on network deployment, and the LP-SS of the neighbor cell can be measured even if the OOK LR is used, the OOK LR can be used for RRM measurement of the neighbor cell. The base station can know the situation of the neighbor cells through interfaces among the base stations or network nodes such as a network control center and the like, so that reasonable configuration is performed.

B) Using OFDM LR to make LP-SS based neighbor cell measurement (same-frequency or different-frequency neighbor cell measurement);

c) Using OFDM LR for PSS or SSS based neighbor cell RRM measurements (co-frequency or inter-frequency neighbor cell measurements), wherein:

The frequencies supported by OFDM LR may be some frequencies defined by the protocol, and the frequencies supported by LR may be relatively few in view of the low cost and low complexity characteristics of LR. But PSS or SSS may be on many frequencies in existing protocols. It is possible that the frequency at which the PSS/SSS of the neighbor cell is located is not a frequency range that can be supported by the OFDM LR, in which case the OFDM LR cannot be used for neighbor cell RRM measurements of PSS or SSS.

Alternatively, a) to c) are applicable to the RRC idle, inactive state or RRC connected. Of these, a) and b) are preferably applied in the RRC idle or inactive state.

Example three:

based on example one, the base station may also be configured to initiate MR relaxed neighbor cell RRM measurements while using LR for first signal based neighbor cell measurements.

A) The MR relaxed neighbor cell RRM measurement may be that the MR performs neighbor cell measurement with a larger measurement period (for example, N times of the LR measurement LP-SS period), and may be further subdivided into co-frequency neighbor cell measurement and inter-frequency neighbor cell measurement. For example:

i. MR makes a relaxed measurement while LR makes neighbor cell measurements;

ii. When the LR measurement is below a certain threshold, the MR makes a relaxed measurement.
