Description

Method and apparatus for radio resource management, RRM, measurements

Technical Field

The present application relates to the field of communications, and more particularly, to a method and apparatus for RRM measurement for radio resource management.

Background

Radio Resource Management (RRM) measurement is a measurement of communication quality of a periodic signal by a terminal, and for example, the content of the measurement may include at least one of received signal power (RSRP), received signal quality (RSRQ), or signal to interference plus noise ratio (SINR). In a conventional scheme, a terminal can measure the RSRP of a periodic signal to determine whether to increase the measurement period of RRM, and the number of measurement samples remains unchanged, so that the measurement power consumption of RSRP can be reduced.

However, in a New Radio (NR) system, since a coverage of a network device is relatively small, for example, ISD is 200, even though a terminal may still have good performance in a partial area of a coverage edge. The terminal may enter other cells at any time in these areas, and if the measurement period of the terminal is relatively long and the moving speed is relatively high, the measurement result obtained by RRM measurement cannot timely reflect the change, resulting in poor quality of received signals, which may cause a handover failure in the cell, thereby causing a relatively high power consumption overhead of the terminal. That is, in the conventional scheme, the terminal can only adjust the RRM measurement mode by increasing the RRM measurement period, and the adjustment of the RRM measurement mode still causes a large overhead for the terminal.

Disclosure of Invention

The application provides a method and a device for RRM measurement, which can reduce the power consumption overhead of a terminal.

In a first aspect, a method for RRM measurement for radio resource management is provided, the method comprising: the terminal performs RRM measurement to obtain a measurement result; the terminal receiving a measurement condition for RRM measurement from the network device; the terminal determining whether the measurement result satisfies a measurement condition of the RRM measurement; the terminal relaxes the RRM measurement if it is determined that the measurement result satisfies the measurement condition.

The network equipment determines a measurement condition of RRM measurement and informs the measurement condition to the terminal, and the terminal performs RRM measurement and determines whether the measurement condition is met according to a measurement result, thereby determining whether to relax the RRM measurement. That is to say, the terminal may flexibly adjust the RRM measurement mode according to the measurement condition configured by the network device, that is, the terminal performs the RRM measurement by using the appropriate RRM measurement mode, thereby helping to reduce the power consumption overhead of the terminal.

In some possible implementations, the measurement condition under which the terminal receives the RRM measurement from the network device includes: the terminal receives indication information indicating a measurement condition for the RRM measurement from the network device.

Specifically, the terminal may learn the measurement condition of the RRM measurement through indication information received from the network device, where the indication information may directly indicate the measurement condition of the RRM measurement or indirectly indicate the measurement condition of the RRM measurement, and signaling overhead may be saved compared to directly sending the measurement condition.

In some possible implementations, the method further includes: the terminal determines not to relax the RRM measurement if it is determined that the measurement result does not satisfy the measurement condition.

The terminal can flexibly adjust the measurement mode of the RRM measurement according to the measurement condition configured by the network device, namely the terminal does not relax the RRM measurement under the condition that the RRM measurement mode does not need to be adjusted, thereby being beneficial to reducing the power consumption overhead of the terminal.

In some possible implementations, the measurement condition includes an association of the measurement result with at least one of a channel quality threshold, a reference signal index, a synchronization signal block index, or a motion velocity threshold.

The measurement condition may include that the measurement result is associated with any one of a channel quality threshold, a reference signal index, a synchronization signal block index or a motion speed threshold, or is associated with multiple ones of the channel quality threshold, the reference signal index, the synchronization signal block index or the motion speed threshold, so that the measurement condition is more refined, the terminal can more accurately select a suitable RRM measurement mode, and the power consumption overhead of the terminal is further reduced.

In some possible implementations, the measurement condition includes: the magnitude relation of the measurement result and at least one channel quality threshold value, and/or the mapping relation of the measurement result and at least one reference signal index, and/or the mapping relation of the measurement result and at least one synchronous signal block index, and/or the magnitude relation of the measurement result and at least one motion speed threshold value.

The measurement condition may be a magnitude relationship with at least one channel quality threshold. The channel quality threshold may be one or more. For example, in the case where the channel quality threshold is one, the measurement condition may be greater than the first quality threshold, or less than the first quality threshold. I.e. above the first quality threshold no relaxation of RRM measurements is possible, and below the first quality threshold RRM measurements is possible. Or the RRM measurement relaxation may be performed if the RRM measurement is greater than the first quality threshold, and the RRM measurement relaxation may not be performed if the RRM measurement is less than the first quality threshold. For another example, in the case where the channel quality threshold is plural, the measurement condition may be greater than the first quality threshold and less than the second quality threshold. I.e. greater than the first quality threshold and less than the second quality threshold, the relaxation of RRM measurements is performed. And when the quality is smaller than the first quality threshold or larger than the second quality threshold, the RRM measurement is not relaxed. As another example, the measurement condition may be greater than a first quality threshold or less than a second quality threshold. I.e. greater than the first quality threshold and less than the second quality threshold, no relaxation of RRM measurements may be performed. The relaxation of RRM measurements may be performed either less than the first quality threshold or greater than the second quality threshold. That is to say, according to the embodiment of the application, the terminal can select a more appropriate RRM measurement mode according to the current channel quality, and power consumption overhead of the terminal is further reduced.

In some possible implementation manners, in the case of a connection state, the channel quality threshold is a preset threshold and a first offset value measured by a co-frequency cell; under the condition of the idle state, the channel quality threshold is a preset threshold and a second offset value measured by the adjacent cell.

The network equipment can set the measurement condition according to the preset quality threshold value, and power consumption overhead of determining parameters in the measurement condition is reduced.

In some possible implementations, the channel quality includes at least one of a received signal power, RSRP, a received signal quality, RSRQ, or a signal-to-interference-and-noise ratio, SINR.

The channel quality threshold may be selected by the network device from at least one of RSRP, RSRQ, or SINR, that is, the embodiment of the present application provides a way to set a quality threshold in a preset condition.

In some possible implementations, the terminal relaxing the RRM measurement in case it is determined that the measurement result satisfies the measurement condition includes: the terminal increases the period of the RRM measurement if it is determined that the measurement result satisfies the measurement condition; and/or the terminal reduces the number of measurement samples in case that the measurement result is determined to satisfy the measurement condition; and/or the terminal reduces the measurement number of the adjacent areas under the condition that the measurement result meets the measurement condition; and/or the terminal reducing the number of RRM measurement beams if it is determined that the measurement result satisfies the measurement condition.

The terminal may adjust the RRM measurement mode when it is determined that the measurement result satisfies the measurement condition, specifically, increase a period of the RRM measurement, reduce the number of measurement samples in the neighboring area, or reduce the number of RRM measurement beams. The embodiment of the application provides a plurality of measurement modes for adjusting the RRM measurement, and improves the flexibility for adjusting the RRM measurement.

Fig. 2 is a schematic flow chart of a method for RRM measurements according to an embodiment of the present application.

The network device determines a measurement condition for RRM measurements 201.

It should be noted that the measurement condition may be regarded as a specified measurement rule.

Optionally, the measurement condition comprises an association of the measurement result with at least one of a channel quality threshold, a reference signal index, a synchronization signal block index or a motion speed.

Specifically, the network device may configure the terminal with a measurement condition in which the measurement result is associated with at least one of a channel quality threshold, a reference signal index, a synchronization signal block index, or a motion speed threshold. That is, the terminal may take various reference factors into account to perform RRM measurement adjustment.

Optionally, the measurement condition may specifically include a magnitude relationship between a measurement result and at least one of the channel quality thresholds.

In particular, the measurement condition may be a magnitude relation of the measurement result to at least one channel quality threshold. The channel quality threshold may be one or more.

For example, in the case where the channel quality threshold is one, the measurement condition may be greater than the first quality threshold, or less than the first quality threshold. I.e. above the first quality threshold no relaxation of RRM measurements is possible, and below the first quality threshold RRM measurements is possible. Or the RRM measurement relaxation may be performed if the RRM measurement is greater than the first quality threshold, and the RRM measurement relaxation may not be performed if the RRM measurement is less than the first quality threshold.

For another example, in the case where the channel quality threshold is plural, the measurement condition may be that the measurement result is greater than the first quality threshold and less than the second quality threshold. I.e. greater than the first quality threshold and less than the second quality threshold, the relaxation of RRM measurements is performed. And when the quality is smaller than the first quality threshold or larger than the second quality threshold, the RRM measurement is not relaxed.

As another example, the measurement condition may be that the measurement result is greater than a first quality threshold or less than a second quality threshold. I.e. greater than the first quality threshold and less than the second quality threshold, no relaxation of RRM measurements may be performed. The relaxation of RRM measurements may be performed either less than the first quality threshold or greater than the second quality threshold.

Optionally, the channel quality threshold may be determined by the network device according to at least one of RSRP, RSRQ, or SINR.

In particular, the channel quality threshold may be selected by the network device from at least one of RSRP, RSRQ, or SINR. The threshold may be based on measurements of one sample or K samples, and the value of K may be fixed. For example, the network device is agreed with the terminal or specified by the protocol, and may also be configured by the network device. K can take any value of 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15, 16.

The samples may be samples obtained by processing the physical layer reference signal, samples obtained by physical layer filtering, or samples obtained by high layer filtering (e.g., L3-filter).

Optionally, the quality threshold may be determined according to an intra-frequency cell measurement preset threshold (S-measure), or according to a neighbor measurement preset threshold (criterion S).

Specifically, in the case where the terminal is in an idle state (idle), the quality threshold may be determined by the network device according to a threshold of criterion S. In the case where the terminal is in the connected state, the quality threshold may be determined by the network device according to the threshold of the S-measure. That is, in a fixed scenario, a fixed value may be used as the quality threshold, and the network device is not required to specifically indicate the quality threshold, thereby reducing signaling overhead. For example, in the case of the terminal in the idle state, the quality threshold may be the Qrxlevmeas value + a first offset value (offset1), or the Qqualmeas value + a second offset value (offset 2).

The first offset value and the second offset value may be preset or configured by a network device, and the present application does not limit the values.

The meaning of criterion S is that when Srxlev >0AND Square >0, the terminal does not perform cell selection. Wherein Srxlev ═ Qrxlevmeas- (Qrxlevmin + Qrxlevminoffset) -Pcomnpensation-

Qoffset; squal ═ Qqualmeas- (Qqualmin + Qqualmin offset) -qoffsetemp. Wherein the parameter list is shown in the following table.

The s-MeasureConfig is an RSRP threshold value for the terminal to determine whether to perform non-serving cell measurement. The threshold may be an SSB-based RSRP or a CSI-RS-based RSRP.

The Qrxlevmeas value may be set to srxlev equal to 0, or may be set to squal equal to 0.

It is understood that the offset1 or the offset2 can be any one of 0,2,4,4.5,6,8,9,10,12,14,16,18,20,22,24,26,28, 30.

Alternatively, the measurement condition may be a mapping relationship of the measurement result and at least one reference signal index.

Specifically, the reference signal index may be 1 or more. For example, a portion of the reference signal indices may be used to indicate relaxation that RRM measurements may be made, and another portion of the reference signal indices may be used to indicate relaxation that RRM measurements may not be made. If only one reference signal index (e.g., a first reference signal index) is included in the measurement condition, in one scenario, the first reference signal index may indicate a relaxation for making RRM measurements; in another scenario, the first reference signal index may also indicate that no relaxation of RRM measurements may be possible.

Alternatively, the reference signal index may be a CSI-RS index, an SSB index, or a DMRS index, a power saving signal index, an index of a tracking signal, and other reference signal indexes.

Specifically, the CSI-RS index may specifically be a CSI-RS resource indication, and may also be an index of the CSI-RS resource indication.

It should be understood that the CSI-RS resource indication may be implemented by a CSI-RS resource index, or may be implemented in other manners, which is not limited in this application.

Alternatively, the measurement condition may specifically be a mapping relationship between the measurement result and at least one synchronization signal block index. For example, if the SSB index indicates that the signal is an index of a cell edge, the terminal may not perform the relaxation of the RRM measurement. Therefore, the terminal is prevented from carrying out the relaxation of RRM measurement at the edge of the cell, and the cell switching of the terminal is influenced, so that the performance of the terminal is reduced. That is to say, the embodiment of the application improves the performance of the terminal.

Alternatively, the network device may configure the reference signal index through a bitmap (bitmap).

Specifically, the bitmap may have a mapping relationship with the reference signal index. The bitmap may be mapped based on a single reference signal index or based on a set of reference signals. For example, the number of reference signals is 8, and 8 bits are used to map the reference signal indexes of the 8 reference signals.

It should be noted that, in the case that the bitmap is mapped based on a single reference signal index, each bit in the bitmap may have a mapping relationship with the single reference signal index, or different values of all bits in the bitmap respectively have a mapping relationship with the single reference signal index.

It should be further noted that a value "0" of the bit indicates that the RRM measurement can be relaxed, and a value "1" of the bit indicates that the RRM measurement cannot be relaxed. For example, using index2, index3, and index6 to denote reference signal index (index) of 00110010, no relaxation of RRM measurements may be made.

Alternatively, the measurement condition may specifically be a mapping relationship between the measurement result and at least one synchronization signal block index.

Specifically, the index of the synchronization signal block may be 1 or more, a part of the synchronization signal block indexes may be used to indicate relaxation in which RRM measurement may be performed, and another part of the synchronization signal block indexes may be used to indicate relaxation in which RRM measurement may not be performed.

Alternatively, the network device may configure the synchronization signal block index through a bitmap (bitmap).

Specifically, the bitmap may have a mapping relationship with the synchronization signal block index. The bitmap may be mapped based on which sync block or based on groups of sync blocks. For example, 16 SSBs are divided into 4 groups of 4 SSBs, so that 8 bits are needed to indicate whether RRM measurements are to be made.

It should be noted that, in the case that the bitmap is mapped based on a single synchronization signal block index, each bit in the bitmap may have a mapping relationship with the single synchronization signal block index, or different values of all bits in the bitmap respectively have a mapping relationship with the synchronization signal block index. For example, 0000 corresponds to SSB 0and 0001 corresponds to SSB 1.

Alternatively, the measurement condition may be a magnitude relationship of the measurement result to at least one motion speed threshold.

Specifically, the movement speed may refer to a movement speed of the terminal, and may also refer to a movement speed of the network device.

Alternatively, the measurement condition may be a magnitude relationship with at least one motion speed threshold and at least one quality threshold.

Specifically, when the movement speed of the terminal is less than or equal to V1, the terminal performs the relaxation of the RRM measurements according to the quality threshold 1 and/or offset 1; when the speed of the terminal is greater than V1 and less than or equal to V2, the terminal performs the relaxation of RRM measurement according to quality threshold 2 and/or offset 2; when the speed of the terminal is greater than V2 or equal to or less than V3, the terminal performs the relaxation of RRM measurements according to the quality threshold 3 and/or the offset interval 3; when the velocity of the terminal is greater than V3, the terminal cannot make the relaxation of the RRM measurement.

It should be noted that the movement speed threshold may be one or more. For example, the motion speed threshold is 2, i.e., V1 and V3.

It should be understood that the velocity response of the terminal may be a doppler shift, the number of cells that have passed through a certain period of time, the number of SSBs that have passed through a certain period of time, or the velocity response may be determined according to the location of the terminal. The speed of the terminal can be indicated by the network equipment, or the terminal can be determined according to the motion state of the terminal. The terminal can also report its speed to the network device.

It is also understood that the value of V1 may be any one of 1,2,3,4,5,6,7,8,9,10 km/h. The value of V1 may be configured by the network device or fixed (specified by the protocol or agreed by the network device and the terminal); the value of V2 may be any one of 10,15, 20, 25, 30,35,40,45,50,55,60 km/h. The value of V2 may be configured by the network device or fixed (specified by the protocol or agreed by the network device and the terminal); the value of V3 may be any one of 60,70, 80, 90,100,110,120 km/h. The value of V3 may be configured by the network device or fixed (specified by the protocol or agreed by the network device and the terminal).

Alternatively, the measurement condition may be a magnitude relation with at least one quality threshold and a mapping relation with at least one synchronization signal block index.

Specifically, different synchronization signal blocks may correspond to different thresholds, and the network device may configure different thresholds according to the SSB index. For example, the relaxation threshold of SSB0 is Th1, and the relaxation threshold of SSB1 is Th 2. The indices of the SSBs at the same threshold may be a set, and the index set of SSBs at the high threshold may include the index sets of SSBs at the low threshold, e.g., Th1> Th2, whose reference signal index sets are set1 and set2, respectively.

Alternatively, the measurement condition may be a magnitude relation with at least one motion speed threshold and a mapping relation with at least one reference signal index.

Specifically, when the velocity of the terminal is less than or equal to V1, the terminal may perform relaxation of RRM measurement when performing RRM measurement on the reference signals in reference signal index set 1. When the velocity of the terminal is greater than V1 and less than or equal to V2, the terminal may perform the relaxation of the RRM measurement when performing the RRM measurement on the reference signals in the reference signal index set 2. When the velocity of the terminal is greater than V2 or equal to or less than V3, the relaxation of the RRM measurement may be performed when the reference signals in the terminal reference signal index set 3 perform the RRM measurement. When the velocity of the terminal is greater than V3, the terminal cannot make the relaxation of the RRM measurement.

It should be noted that the set1, the set2, and the set 3 of the reference signals may be determined and configured to the terminal by the network device. Or the set of reference signals may be configured by the terminal itself, and the terminal may also transmit the configured information to the network device. Set1, set2, and set 3 may contain all or part of the reference signal index. The sets 1,2 and 3 may overlap.

It should be further noted that, when configuring the set of reference signals, the network device may also use a difference method for configuration, for example, the set2 includes all the sets 3, the network device may configure the set 3 first, and when configuring the set2, only the remaining portions except 3 in the set2 are configured, so as to reduce the overhead of configuration.

For example, there are 8 SSBs for a cell, where SSB #1,3,4,6,7 is set2 and SSB #6,7 is set 3. The network device may also choose a portion from a large set to be configured as a small set, thereby saving overhead. The first configuration method is that the field configured in the configuration set 3 is 00000011, and in the configuration set2, the field configured is 011100; the second configuration method is that the configuration set2 is 01011011, and then the configuration set 3 is 00011. The network device may also increase or decrease the speed level, and the corresponding aggregation level, in the configuration.

Alternatively, the network device may determine the measurement condition according to the velocity of the terminal, the threshold of the terminal measurement signal, and the location of the SSB where the terminal is located.

202, the terminal performs RRM measurement to obtain a measurement result.

Specifically, the terminal measures the periodic signal, specifically, measures the channel quality, and measures whether the reference signal is received. Accordingly, the measurement result obtained by the measurement signal may be a channel quality size, an index of the received reference signal, or a motion speed of the terminal obtained from the measurement signal.

The network device sends 203 the measurement conditions for the RRM measurement to the terminal. Accordingly, the terminal receives the measurement condition of the RRM measurement from the network device.

It should be noted that, in this embodiment, the order of step 202 or step 203 is not limited.

It should be further noted that the measurement condition obtained by the terminal device may be pre-agreed with the network device, or specified by a protocol, or may also be pre-configured by the network device, so that the embodiment does not need to perform step 201 and step 203.

Alternatively, the network device may transmit indication information to the terminal, where the indication information indicates the measurement condition of the RRM measurement.

Alternatively, the indication information may be carried in any one of a Physical Broadcast Channel (PBCH), Remaining Minimum System Information (RMSI), a System Information Block (SIB) 1, an SIB2, an SIB3, a media access control element (MAC-CE), Downlink Control Information (DCI), Radio Resource Control (RRC), and system information.

The terminal determines 204 whether the measurement result satisfies the measurement condition for the RRM measurement.

The terminal relaxes the RRM measurement in case it is determined that the measurement result satisfies the measurement condition 205.

Specifically, the network device determines a measurement condition for RRM measurement and informs the terminal of the measurement condition, and the terminal performs the RRM measurement and determines whether the measurement condition is satisfied according to a measurement result, thereby determining whether to relax the RRM measurement. That is to say, the terminal may flexibly adjust the RRM measurement mode according to the measurement condition configured by the network device, that is, the terminal performs the RRM measurement by using the appropriate RRM measurement mode, thereby helping to reduce the power consumption overhead of the terminal.

Optionally, the terminal does not relax the RRM measurement if the measurement condition is not satisfied.

Specifically, in general, a terminal has a fixed RRM measurement period, and the terminal may initially perform RRM measurement based on the RRM measurement period. In case the terminal satisfies the measurement condition, the RRM measurement period is adjusted. And in the case that the measurement condition is not met, performing RRM measurement by using the fixed RRM measurement period.

Optionally, the relaxing of the RRM measurement may specifically be to increase a period of the RRM measurement, or decrease a number of measurement samples, or decrease a number of measurements of the neighboring region, or decrease a number of RRM measurement beams, or decrease a number of measurements of the neighboring frequency. That is to say, the terminal can reasonably adjust the measurement mode of RRM measurement, thereby saving the power consumption overhead of the terminal.

It should be noted that the neighboring area may be a neighboring cell. The adjacent frequency refers to adjacent frequency points, and the frequency point may specifically be a frequency point of a reference signal.

Alternatively, the relaxation of RRM measurements by the terminal may be determined from the aforementioned offset.

In particular, the terminal may be relaxed differently for different offset values or different quality thresholds, thereby increasing the flexibility of RRM measurement and further saving the overhead of the terminal. For example, when the terminal measures a reference signal with a measurement value Y, the threshold (quality threshold or motion speed threshold) of the preset condition configured by the network device is X. If Y is larger than X by a factor of Z, the terminal may double the RRM measurement period. Wherein Z may be any one of 1,2,3,4,5,6,7,8, 10 dB.

For example, if Z is 3dB, the measurement period is doubled, which is proportional. If X is-120 dBm, the RRM measurement period can be doubled when Y has a value of-117 dBm. The period of RRM measurement may be increased by one time, or the number of samples of the RRM period may be reduced by half or reduced by 1, or the number of beams of the RRM measurement may be reduced by half, which is not limited in this application.

Optionally, after step 205, the terminal may further send feedback information to the network device after performing the relaxation of the RRM measurement, where the feedback information is used to indicate a relaxation parameter.

It should be noted that, after receiving the feedback information, the network device may also perform cell handover on the terminal, or trigger a cell handover procedure.

For example, the feedback information may indicate the number of samples used for filtering, the number of measurement samples decreased, and the number of times the measurement period is increased.

Optionally, the terminal may perform cell handover after step 205, or trigger a cell handover procedure.

Therefore, in the method for RRM measurement in the embodiment of the present application, the network device determines a measurement condition for RRM measurement, and notifies the terminal of the measurement condition, and the terminal performs RRM measurement and determines whether the measurement condition is satisfied according to a measurement result, and further determines whether to relax the RRM measurement. That is to say, the terminal may flexibly adjust the RRM measurement mode according to the measurement condition configured by the network device, that is, the terminal performs the RRM measurement by using the appropriate RRM measurement mode, thereby helping to reduce the power consumption overhead of the terminal.

The terminal measures the channel quality to obtain a channel quality measurement result, and determines whether the measurement condition is met according to the channel quality measurement result, so as to determine whether to relax the RRM measurement. That is to say, the terminal may flexibly adjust the RRM measurement mode according to the measurement condition configured by the network device, that is, the terminal performs the RRM measurement by using the appropriate RRM measurement mode, thereby helping to reduce the power consumption overhead of the terminal.

The terminal measures the reference signal to obtain a signal measurement result, and determines whether the measurement condition is met according to the channel quality measurement result, so as to determine whether to relax the RRM measurement. That is to say, the terminal may flexibly adjust the RRM measurement mode according to the measurement condition configured by the network device, that is, the terminal performs the RRM measurement by using the appropriate RRM measurement mode, thereby helping to reduce the power consumption overhead of the terminal.
