Description

Method and device for reporting beam measurement result

The application filing date is 2021, 8/6/202110904300.2, entitled priority of a method and apparatus for reporting beam measurement result.

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for reporting a beam measurement result.

Background

As the holding amount of terminals increases, the pressure of cells increases. When the load of the cell is exceeded, the network response may be slowed down, resulting in a poor usage experience for the user. Moreover, the cell is in an overload state for a long time, which may also cause hidden troubles. Therefore, cell switching can be performed to reduce load (offloading). In addition, the terminal also needs to perform cell handover frequently during the moving process.

How to find a suitable cell for handover for the terminal needs to be considered.

The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

Referring to fig. 2, a schematic flow chart of a method for reporting a beam measurement result is provided, where the method includes the following steps:

step 21: the network device sends the beam measurement configuration information to the terminal, and correspondingly, the terminal acquires the beam measurement configuration information sent by the network device.

The beam measurement configuration information is used for indicating the measurement resources of the first type cells and the measurement resources of the second type cells.

In one example, the beam measurement configuration information sets resource setting information for a resource.

It should be noted that the beam measurement configuration information includes report setting information and resource setting information configured by the network device.

The measurement resources are used for the terminal to perform beam measurements. The measurement resource may be a measurement resource corresponding to a synchronization signal and PBCH block (SSB) or a measurement resource corresponding to a channel state information-reference signal (CSI-RS).

Optionally, the first type cell is a current serving cell, and the second type cell is a neighboring cell of the current serving cell. The second type of cell is a plurality of cells.

Step 22: the terminal reports K wave beam measuring results, and correspondingly, the network equipment receives the K wave beam measuring results reported by the terminal.

The K beam measurement results are K beam measurement results selected from a first candidate beam measurement result corresponding to a first type cell and a second candidate beam measurement result corresponding to a second type cell, where K is an integer greater than or equal to 1, the first type cell is a current serving cell, and the second type cell is an adjacent cell to the current serving cell.

The first candidate beam measurement is: a first initial beam measurement result obtained by performing beam measurement on the measurement resources of the first type cell; the second candidate beam measurement result is: performing beam measurement on the measurement resources of the second type of cell to obtain a second initial beam measurement result, and processing the second initial beam measurement result to obtain a second beam measurement result; or,

the first candidate beam measurement result is: performing beam measurement on the measurement resources of the first type of cell to obtain a first initial beam measurement result, and processing the first initial beam measurement result to obtain a first beam measurement result; the second candidate beam measurement is: a second initial beam measurement result obtained by performing beam measurement on the measurement resources of the second type cell; or,

the first candidate beam measurement is: performing beam measurement on the measurement resources of the first type cell to obtain a first initial beam measurement result, and processing the first initial beam measurement result to obtain a first beam measurement result; the second candidate beam measurement is: and performing beam measurement on the measurement resources of the second type of cell to obtain a second initial beam measurement result, and processing the second initial beam measurement result to obtain a second beam measurement result. The first candidate beam measurement result may be a first beam measurement result obtained by processing the first initial beam measurement result, and the second candidate beam measurement result may be a second beam measurement result obtained by processing the second initial beam measurement result. As the initial beam measurements are processed, the likelihood that the processed second beam measurements will be selected is increased. In this way, the reported K beam measurement results may include beam measurement results of cells of different types at a high probability. Compared with the beam measurement result only comprising one type of cell, the method can enable the network equipment to select the switching cell for the terminal more flexibly and accurately so as to realize that the terminal finds a proper cell for switching.

The protocol may specify that multiple (e.g., K) beam measurements reported by the terminal are from heterogeneous cells. Or the network device may configure the terminal, and the multiple beam measurement results reported by the terminal come from different types of cells.

Of course, in a handover scenario, the reported multiple (e.g., K) beam measurement results may also be from only the second type cell (neighboring cell).

The sum of the number of first candidate beam measurements and the second candidate beam measurements is greater than or equal to K. Examples of K beam measurements selected from a first candidate beam measurement corresponding to a first type of cell and a second candidate beam measurement corresponding to a second type of cell are as follows:

example 1: the plurality of candidate beam measurements (including the first candidate beam measurement and the second candidate beam measurement) are sorted in descending order, and the top K candidate beam measurements are selected.

The number K of beam measurement results reported by the terminal may be predefined by a protocol, or may be indicated to the terminal by the network device. For example, the network device may configure 1 reporting setting (reporting setting) to the terminal to notify the terminal of the number K of beam measurement results reported, where K is 4, 5, or 8, for example. The report setting (reporting setting) may be located in the beam measurement configuration information in step 21, or may be independent of the beam measurement configuration information in step 21.

Example 2: the first type of cell selects K1 beam measurements and the second type of cell selects K2 beam measurements, K1+ K2= K, K1 is an integer greater than or equal to 1 and K2 is an integer greater than or equal to 1. And sequencing the first candidate beam measurement results from large to small, and selecting the first K1 candidate beam measurement results. And sequencing the second candidate beam measurement results in a descending order, selecting the first K2 candidate beam measurement results, and introducing the specific selection process in the following way.

The number K1 of the beam measurement results of the first type cell and the number K2 of the beam measurement results of the second type cell, which are reported by the terminal, may be predefined by a protocol, or may be indicated to the terminal by the network device. For example, the network device may configure 1 reporting setting (report setting) to the terminal, so as to notify the terminal of the number K1 of beam measurement results of the first type of cell and the number K2 of beam measurement results of the second type of cell that are reported, where K1 is 1, 4, or 6, and K2 is 2, 3, or 4. The report setting (reporting setting) may be located in the beam measurement configuration information in step 21, or may be independent of the beam measurement configuration information in step 21.

The two methods can be used to obtain that the K wave beam measurement results reported by the terminal can come from one type of cell or from different types of cells. It may also be understood that at least one of the K beam measurements is from a second candidate beam measurement.

The beam measurements include at least one of: reference signal received power RSRP, or signal to interference plus noise ratio SINR, or differential reference signal received power RSRP, or differential signal to interference plus noise ratio SINR. For example, these beam measurements are layer 1 beam measurements, such as: layer 1-reference signal received power L1-RSRP; layer 1-signal to interference plus noise ratio L1-SINR; differential layer 1-reference signal received power L1-RSRP; differential layer 1-signal to interference plus noise ratio L1-SINR.

In an alternative example, the terminal may further indicate to the network device: an identifier { e.g., reference signal identifier (CRI) or Synchronization Signal Block Resource Indicator (SSBRI) } of the measurement Resource corresponding to each reported beam measurement result, that is, the network device is told that the K beam measurement results are measured based on which beam measurement Resource respectively.

The above describes initial beam measurements, which may be understood as measurements directly obtained from measurement resources. The processing of the initial beam measurement results is also described above, and the following is divided into two ways, which describe the processing of the initial beam measurement results.

Mode 1: performing an operation on the first beam measurement result and/or the second beam measurement result.

For example, processing the first initial beam measurement comprises:

respectively carrying out operation processing on each first initial beam measurement result and a parameter value;

for example, processing the second initial beam measurement includes:

and respectively carrying out operation processing on each second initial beam measurement result and the parameter value.

The parameter value may be referred to as an offset value.

The parameter values may include a calculated offset value used for the add/subtract calculation.

The parameters may also include a scaling factor that is used to perform the multiply/divide calculation.

The parameter values may also include calculating offset values and scaling factors.

The operation processing of each first initial beam measurement result and the parameter value includes one of the following:

subtracting the calculated offset values from the first initial beam measurements, respectively;

dividing the first initial beam measurements by a scaling factor, respectively.

The calculated offset value is within a first predetermined range [ -M, M ] dBm, where M is a value greater than zero. For example, M is an integer, e.g., M is 16 or 15 or 17.M may also be a fraction or fraction, with a quantization value of X bits, and granularity of YdB.

Generally, the quality of a beam of a current serving cell is better than that of a beam of a neighboring cell, and when a beam measurement result is Reference Signal Receiving Power (RSRP), the RSRP of the current serving cell is greater than that of the neighboring cell. In this way, the RSRP of the neighboring cell is less likely to be reported. Based on this, the RSRP of the current serving cell may be reduced to a small extent, so as to improve the probability of reporting the RSRP of the neighboring cell. In this case, the calculated offset value subtracted from the first initial beam measurement may be a value greater than 0. Alternatively, when the beam measurement is the Signal to Interference plus Noise Ratio (SINR), a scaling factor may be used to increase the probability of SINR reporting of neighboring cells. The same principle as the RSRP principle is not described again.

The operation processing of each second initial beam measurement result and the parameter value includes one of the following:

adding the calculated offset values to the second initial beam measurements, respectively;

multiplying the second initial beam measurements by the scaling factors, respectively.

The scaling factor is within a second predetermined range [ a, b ], wherein b is greater than a and a is greater than zero. For example, b is an integer or fraction or decimal. For example b is 3, or 4 or 5.

Generally, the quality of the beam of the current serving cell is better than that of the beam of the neighboring cell, and when the beam measurement result is RSRP, the RSRP of the current serving cell is greater than that of the neighboring cell. Thus, the RSRP of the neighboring cell is less likely to be reported. Based on this, the RSRP of the neighboring cell can be increased to a greater extent, so as to improve the probability of reporting the RSRP of the neighboring cell. In this case, the calculated offset value added to the second initial beam measurement may be a value greater than 0. Or, when the beam measurement result is SINR, the scaling factor may be used to improve the probability of SINR reporting of the neighboring cell. The same principle as the RSRP principle is not described again.

In one example, the network device sends the indicated parameter value to the terminal, and accordingly, the terminal receives the parameter value indicated by the network device. The parameter value can be pre-defined by a protocol, so that the parameter value does not need to be sent to a terminal by network equipment, and signaling resources can be saved. Of course, the network device may also indicate the parameter value to the terminal, and accordingly, the terminal receives the parameter value indicated by the network device, and the current communication requirement may be better met through the indication of the network device.

The indication may be sent directly or implicitly. The network device may directly send the parameter value to the terminal, or the network device may implicitly notify the terminal through the indication information. For example, the network device and the terminal store different corresponding relationships between parameter values and index values, and the terminal is notified by the index values corresponding to the parameter values. For example, if there are 4 parameter values, the index values are 0, 1, 2, and 3, and these four values need to be distinguished by at least 2 bits. When the network device sends an index value of 3 (which is indicated by 11, for example, and occupies 2 bits) to the terminal, it indicates that the 4 th parameter value is adopted. Signaling may be saved by means of an index value.

The network device may indicate the parameter value to the terminal through a high-layer signaling, or a Downlink Control Information (DCI), or a Medium Access Control (MAC) signaling.

The number of the parameter values may be 1, or may be multiple, and when the number of the parameter values is multiple, the parameter values corresponding to at least two cells are different. For example, the first type of cells may correspond to the same parameter value, the second type of cells may correspond to the same parameter value, and different types of cells may correspond to different parameter values. As another example, different parameter values may be associated with each cell. For another example, one or more cells may correspond to the same parameter value, and another one or more cells may correspond to the same parameter value.

Several examples are presented below:

Mode 2: and screening the initial beam measurement results of the plurality of second-type cells.

In this embodiment 2, the first candidate beam measurement result is: and performing beam measurement on the measurement resources of the first type cell to obtain a first initial beam measurement result, or performing beam measurement on the measurement resources of the first type cell to obtain a first initial beam measurement result, and then processing the first initial beam measurement result to obtain a first beam measurement result. The process of processing the first initial beam measurement result may refer to the above, and is not repeated.

The second candidate beam measurement result corresponding to the second type of cell includes: and performing beam measurement on the measurement resources of the second type of cell to obtain a second initial beam measurement result, and processing the second initial beam measurement result to obtain a second beam measurement result.

In one example, the second beam measurement is: and selecting a target second-class cell from a plurality of second-class cells according to the second initial beam measurement result, and taking a beam measurement result obtained by performing beam measurement on the measurement resource of the target second-class cell as a second beam measurement result.

Alternatively, the minimum value of the preset range may be greater than or equal to the preset beam measurement value.

For example, example 5: an adjacent cell is selected first, and then initial beam measurement results of the adjacent cells are selected.

The base station configures 1 resource setting, which contains 5 resource sets, wherein the first resource set is associated with the first type of cell (current serving cell) and comprises 8 measurement resources { CSI-RS #1, CSI-RS #2, \ 8230;, CSI-RS #8 }.

The resources configured for the adjacent cell 1 comprise { CSI-RS #9, CSI-RS #10, CSI-RS #11 and CSI-RS #12}, the resources configured for the adjacent cell 2 comprise { CSI-RS #13, CSI-RS #14, CSI-RS #15 and CSI-RS #16}, the resources configured for the adjacent cell 3 comprise { CSI-RS #17, CSI-RS #18, CSI-RS #19 and CSI-RS #20}, and the resources configured for the adjacent cell 4 comprise { CSI-RS #21, CSI-RS #22, CSI-RS #23 and CSI-RS #24}. The base station configures the terminal to report 8 beam measurement results, wherein 4 of the beam measurement results come from the first type of cells, and the remaining 4 beam measurement results come from the second type of cells. The terminal firstly measures the resources { CSI-RS #1, CSI-RS #2, \ 8230;, CSI-RS #8} of the first type cell and sorts the obtained initial beam measurement results to obtain a set S1: { L1-RSRP _meas,s1 ，L1-RSRP _meas,s3 ，L1-RSRP _meas,s4 ，L1-RSRP _meas,s2 ，L1-RSRP _meas,s5 ，L1-RSRP _meas,s6 ，L1-RSRP _meas,s7 ，L1-RSRP _meas,s8 }。

When selecting 4 beams from the neighboring cells, the terminal adopts a method of selecting a target neighboring cell (i.e., a target second-type cell) first and then selecting beams in the target neighboring cell. Such as:

step 1: first selecting target adjacent cell

a. The terminal measures the L1-R obtained by 4 adjacent cellsThe SRP value is respectively connected with the preset beam measurement value L1-RSRP _{abs_threshold} Comparing and comparing more than L1-RSRP _{abs_threshold} And the number of the L1-RSRP values is sorted from large to small according to the cell. As illustrated in fig. 3, the order of arrangement is: cell _n3 ,Cell _n4 ,Cell _n1 /Cell _n2 。

b. Greater than L1-RSRP selected in a _{abs_threshold} For each adjacent cell, the number of L1-RSRPs falling within the range of RangeToBestL1-RSRP is compared, and cell sorting is performed in descending order. As shown in fig. 4, the arrangement order is: cell _n4 /Cell _n2 ,Cell _n1 /Cell _n3 。

c. Combining a and b, selecting the optimal adjacent Cell (i.e. the target second type Cell), for example, the optimal adjacent Cell is Cell at this time _n4 。

Step 2: and (3) the terminal sorts the L1-RSRP measurement values of the target adjacent cells selected in the step (1) from large to small, and selects 4 from large to small for reporting. Combining the terminal pair for Cell described in c _n4 And reporting 4L 1-RSRP values from large to small. The final 8L 1-RSRP values reported by the terminal are the first 4 bits { L1-RSRP in the S1 set _meas,s1 ，L1-RSRP _meas,s3 ，L1-RSRP _meas,s4 ，L1-RSRP _meas,s2 } and Cell _n4 Middle 4L 1-RSRP values from large to small.

As shown in fig. 7, an embodiment of the present application further provides a method for reporting a beam measurement result, where the method is executed by a terminal, and the method includes:

step 701, obtaining beam measurement configuration information sent by a network device, where the beam measurement configuration information is used to indicate measurement resources of a cell.

It should be noted that, the beam measurement configuration information may set resource setting information for the resource. The beam measurement configuration information includes report setting information and resource setting information configured by the network device.

It should be further noted that the measurement resource is used for the terminal to perform beam measurement, and the measurement resource may be a measurement resource corresponding to an SSB or a measurement resource corresponding to a CSI-RS.

Step 702, sending first information to the network device, where the first information carries second information and a beam measurement result corresponding to a target cell; the target cell is determined according to the second information; the second information includes: measurement information and/or an identification of the measurement resource.

In this way, the terminal may report the first information to the network device, so that the network device may obtain measurement information (for example, several target cells, which target cells are, which transmission points TRP are, etc.) corresponding to the beam measurement results reported by the terminal, and the beam measurement results are obtained based on which beam measurement resources are measured, respectively.

In this embodiment, the beam measurement result reported by the terminal may include beam measurement results of cells of different types, for example, the beam measurement result of the current serving cell may be included, and the beam measurement result of a cell adjacent to the current serving cell may also be included. Therefore, compared with the beam measurement result only comprising one type of cell, the network device can select the handover cell for the terminal more flexibly and accurately, so as to realize that the terminal finds a proper cell for handover.

In an alternative example, the terminal may indicate (i.e., inform the network device) to the network device, through the identifier of the measurement resource corresponding to each reported beam measurement result, on which beam measurement resource the beam measurement result is measured respectively. Optionally, the identifying of the measurement resource comprises: the reference signal identification CRI and/or the synchronization signal block resource indication SSBRI.

As an optional embodiment, the measurement information comprises at least one of:

(one) the number of the target cells.

I.e. the terminal may indicate to the network device the number of cells that need to be reported with beam measurements.

(II) cell indication information of the target cell; the cell indication information includes at least one of a physical cell identity, PCI, an indication signal, and bitmap information.

That is, the terminal may indicate to the network device which cells the beam measurement result report needs to be performed specifically.

(III) first indication information of a transmission point TRP of the target cell.

Here, the first indication information is used to indicate a transmission point TRP of the target cell.

(IV) the number of first measurements; the first measurement result is an absolute value of the beam measurement results.

Generally, the measurement results of the target cell may be ranked in descending order, and the measurement result ranked first may be reported as an absolute value, and the measurement result ranked second and later may be reported after being differed from the absolute value.

(V) the number of differential measurements; the difference measurement result is a difference value in the beam measurement result.

As another alternative embodiment, the beam measurement result includes at least one of: L1-RSRP; L1-SINR; a difference L1-RSRP; the difference L1-SINR. Here, the above-described process is exemplified as follows:

In addition, the base station configures 1 resource setting (resource setting) including two resource sets (resource sets), wherein the first resource set is associated with the first type of cell (for example, denoted by PCI 1) and includes 2 measurement resources { CSI-RS #1, CSI-RS #2 }; the second resource set is associated with the second type of cell (e.g., denoted by PCI 2) and includes 2 measurement resources { CSI-RS #3, CSI-RS # 4}. The terminal measures the measurement resources of the first type of cell according to the configuration of the base station to obtain 2 beam measurement results, which are respectively: CRI1+ L1-RSRPs1, CRI2+ L1-RSRPs2; the terminal measures measurement resources { CSI-RS #3, CSI-RS #4} of the second type cell according to the configuration of the base station, and obtains 2 beam measurement results, which are respectively: L1-RSRPs3, L1-RSRPs4. The measurement results of the terminal on the first type of cells are obtained by arranging the measurement results from large to small: CRI2+ L1-RSRPs2, CRI1+ L1-RSRPs1; the measurement results of the terminal on the second type of cells are obtained by arranging the measurement results from large to small: CRI3+ L1-RSRPs3, CRI4+ L1-RSRPs4.

In this embodiment, when reporting the measurement result, the terminal may report the measurement result in the form of two parts of content (for example, part1 and Part2 respectively):

for example, part1 reported by the terminal is 2, that is, cell information of a reported target cell (that is, a cell that needs to report a beam measurement result) is 2, which indicates that there are 2 target cells; the reported Part2 Part may include: CRI2+ L1-RSRPs2 (7 bit), CRI1+ (L1-RSRPs 1-L1-RSRPs 2) (4 bit), CRI3+ L1-RSRPs3 (7 bit), CRI4+ (L1-RSRPs 4-L1-RSRPs 3) (4 bit). Wherein, L1-RSRPs2 and L1-RSRPs3 are absolute values, and L1-RSRPs1-L1-RSRPs2 and L1-RSRPs4-L1-RSRPs3 are differential values.

For another example, the reported Part2 Part may also include: (00) + CRI2+ L1-RSRPs2 (7 bit), (00) + CRI1+ (L1-RSRPs 1-L1-RSRPs 2) (4 bit), (01) + CRI3+ L1-RSRPs3 (7 bit), (01) + CRI4+ (L1-RSRPs 4-L1-RSRPs 3) (4 bit). Where "00" is used to indicate cell PCI1 and "01" is used to indicate cell PCI2.

For another example, the Part1 reported by the terminal is (1100), where "1100" is cell information of the target cell, and is specifically used to indicate a bitmap (i.e., a bitmap) of the target cell (i.e., a cell that needs to report the beam measurement result); the reported Part2 Part may include: CRI2+ L1-RSRPs2 (7 bit), CRI1+ (L1-RSRPs 1-L1-RSRPs 2) (4 bit), CRI3+ L1-RSRPs3 (7 bit), CRI4+ (L1-RSRPs 4-L1-RSRPs 3) (4 bit).

In the embodiment of the invention, the beam measurement results reported by the terminal can comprise the beam measurement results of different types of cells, and compared with the beam measurement results only comprising one type of cells, the beam measurement results can enable the network equipment to select the switching cells for the terminal more flexibly and accurately so as to realize that the terminal finds the proper cells for switching.
