When describing the embodiments of the present application, some concepts used in the following description are explained first.

One: Multi-TRP transmission technology.

The protocol standardizes the multi-transmit/receive point/multi-antenna panel scenario. Multiple TRPs can be divided into ideal backhaul lines and non-ideal backhaul lines. When the backhaul is not ideal, ACK/NACK and CSI reports are fed back to each TRP respectively. It is usually applicable to multiple downlink control information (Downlink Control Information, DCI) scheduling, that is, each TRP sends its own physical downlink control channel (Physical downlink control channel, PDCCH), each PDCCH schedules its own physical downlink shared channel (Physical downlink shared channel, PDSCH), multiple control resource sets (Control resource set, CORESET) configured for the UE are associated with different RRC parameters and correspond to different TRPs. Multiple PDSCHs scheduled by multiple DCIs may not overlap, partially overlap, or completely overlap on time-frequency resources. On overlapping time-frequency resources, each TRP performs independent precoding according to its own channel, and the UE receives multi-layer data streams belonging to multiple PDSCHs in the manner of Non-Coherent Joint Transmission (NCJT).

In an ideal backhaul line, scheduling information and UE feedback information can be exchanged between multiple TRPs in real time. In addition to scheduling multiple PDSCHs through the above-mentioned multiple DCIs, a single DCI can also schedule PDSCHs, including the following transmission schemes:

Space Division Multiplexing (SDM): Different data layers of the same transport block (Transport Block, TB) come from NCJT transmission of different TRPs;

Frequency Division Multiplexing (FDM): Different frequency domain resources mapped by the same Redundancy Version (RV) of the same TB are sent from different TRPs or different RVs of the same TB are mapped to different frequency domain resources and sent from different TRPs ;

Time Division Multiplexing (TDM): Multiple repetitions of different RVs of the same TB come from different TRPs, such as repetitions within one slot, or repetitions of multiple slots.

At this time, the ACK/NACK feedback and CSI report can be fed back to any TRP.

Two: Multi-TRP CSI framework.

The CSI configuration resource framework in the multi-TRP scenario is as follows:

In a CSI report setting (CSI report setting) is a CSI report of multiple TRPs, the UE needs to measure the CSI reference signal (CSI Reference Signal, CSI-RS) from different TRPs, so in the CSI resource configuration associated with a CSI report setting ( CSI resource setting) contains S>1 CSI measurement resource set (CSI resource set), each CSI resource set corresponds to a different TRP, has a different quasi co-location (Quasi co-location, QCL).

3. UCI mapping.

(1) Beam reporting.

If the group-based beam reporting (group Based Beam Reporting) field is configured in the high-level parameter CSI Report Config (CSI Report Config), and the report quantity field is configured as "cri-rsrp" or "cri-sinr" or " ssbri-rsrp" or "ssbri-sinr", it indicates that the current CSI report is a beam report. And when the "group Based Beam Reporting" field is "enabled", the UE can only report a pair of beams: including two Channel Measurement Resource (Channel Measurement Resource, CMR) identifiers and their corresponding layer 1 reference signal received power (Layer 1Reference Signal Received Power, L1-RSRP)/Layer 1 Signal to Interference plus Noise Ratio (Layer 1Signal to Interference plus Noise Ratio, L1-SINR) value. Wherein, the CMR identifier includes: CSI Reference Signal Resource Indicator (CSI-RS Resource Indicator, CRI), SSB Resource Indicator (SS/PBCH Block Resource Indicator, SSBRI).

When the "group Based Beam Reporting" field is "disabled", the UE may report the CMR identifiers corresponding to the 4 beams and their corresponding L1-RSRP. When the number of reported beams is greater than 1, report the difference between the other L1-RSRP/L1-SINR values and the maximum value except the maximum value of L1-RSRP/L1-SINR.

Among them, the CRI or SSBRI in the beam report in the multiple transmission and reception point (Multiple Transmit receive point, MTRP) scenario is determined according to the number of reference signals (Reference Signal, RS) in its associated CSI measurement resource set.

(2) UCI mapping of beam reports.

The CSI report can be divided into two parts: the first part (part 1) and the second part (part 2). Among them, Part 1 is of fixed size, which can be configured by the network testing equipment through Radio Resource Control (RRC); Part 2 is of variable length, and the terminal can determine the information to be reported and transmitted according to the size of available uplink resources .

The beam reporting method provided by the embodiment of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.

As shown in Figure 2, this embodiment of the present application provides a beam reporting method, including:

Step 201, the terminal feeds back the channel state information CSI report including the relevant information of the N pairs of beams to the network side device according to the preset rules;

Wherein, the CSI report includes: a first part and a second part, the first part includes information about N1 pairs of beams in the N pairs of beams, N1 is less than or equal to N, and both N1 and N are positive integers; In the case where N1 is smaller than N, the second part includes information about N2 pairs of beams among the N pairs of beams, and the sum of N1 and N2 is equal to N.

In this embodiment, the preset rule may include a mapping rule for mapping information related to N pairs of beams in the CSI report, and may also include mapping the CSI report to available uplink resources for transmission and the available uplink resources cannot When carrying the relevant information of all beams, the priority rule and discarding rule when discarding the relevant information content of the beam. The N pairs of beams are beams that can be received by the terminal at the same time, and N is a positive integer, such as N=2, 4, and so on. The value of N may be configured by the network side device through RRC.

When the terminal reports the relevant information of the N pairs of beams, the relevant information of the N pairs of beams is mapped to the CSI report, and the CSI report is fed back to the network side device through the available uplink resources of the target, so as to realize the reporting of beam information of multiple TRPs . Specifically, the CSI report includes a first part (ie Part1) and a second part (ie Part2), and the relevant information of the N pairs of beams can be all mapped to Part1; or, part of it is mapped to Part1, and the rest is mapped to Part2, That is: N1 beam-related information is placed in Part1, N2 beam-related information is placed in Part2, N1+N2=N, because the size of Part2 is variable, it avoids a large UCI load when reporting multiple beam-related information at the same time , which can reduce UCI fixed bit overhead. The specific mapping distribution of the beam-related information may be determined according to the configuration of the network-side device or the terminal itself according to a predetermined rule.

Wherein, the target available uplink resource includes a physical uplink control channel (Physical Uplink Control Channel, PUCCH) or a physical uplink control channel (Physical Uplink Shared Channel, PUSCH).

When the uplink resources are insufficient or there is a resource conflict between the available uplink resources and other resource scheduling, that is, the available uplink resources cannot bear all the reported information, the content of the reported information may be discarded according to preset rules.

In this embodiment, the CSI report containing information about the N pairs of beams is divided into two parts. The first part includes the channel measurement resource indication and/or layer 1 measurement value of the N1 pair of beams, and may also include the arrangement order of the N1 pair of beams and the channel The corresponding relationship between the measurement resource indication and the channel measurement resource set; the second part includes the relevant information of the N2 pair of beams, the arrangement order of the N2 pair of beams, and the corresponding relationship between the channel measurement resource indication and the channel measurement resource set. After the CSI report is determined, the CSI report is mapped to the target available resource according to the priority rule and sent to the network side device.

In the embodiment of the present application, when the terminal reports beam-related information, it can put the related information of N pairs of beams in the CSI report according to the preset rules and report it, which realizes the flexible configuration of beam-related information reporting and can reduce the number of beam-related information carried. The fixed bit overhead of the UCI ensures the reliable reporting of beam-related information and effectively avoids the loss of high-priority beam information due to the large fixed load of UCI.

Wherein, the relevant information of the N1 pair of beams among the N pairs of beams is placed in Part1 of the CSI report, and the value of the N1 can be configured by the network side device through the radio resource control RRC; or, the value of the N1 is the terminal determined according to the first rule. The first rule can be configured for the network side device, or can be customized for the terminal.

Specifically, the first rule includes at least one of the following:

1) The relevant information of the beam pair with the highest measurement value of layer 1 is located in the first part; that is, the first rule indicates that the relevant information of the beam pair with the highest measurement value of layer 1 is located in Part1, that is, N1=1, and the terminal will use layer 1 The relevant information of a pair of beam pairs with the highest measurement value is mapped to the Part1, and when N is greater than N1, the relevant information of other beam pairs is placed in Part2.

2) Determine the value of N1 according to the proportion of N1 in N. Wherein, the proportion of N1 in N can be configured by the network side device, for example: 1:4, 1:2 and so on. One or more proportions of N1 in N can be configured, and when multiple proportions are included, the terminal can select a proportion to determine the value of N1 according to the measurement situation.

3) Determine the value of N1 according to the measured value of layer 1 and the first threshold. The first threshold may be configured by the network side device, and the first threshold is a threshold of a measurement value. The terminal may compare the layer 1 measurement value of each beam with the first threshold, for example, compare the values of beam pairs greater than the first threshold Relevant information is placed in Part1, and then the value of N1 is determined.

Wherein, the terminal may report the value of N1, and optionally, the first part further includes: the value of N1. Specifically, when the first rule is predefined for the terminal, the first part may include the value of N1.

In this embodiment, in order to ensure that the network-side device and the terminal have a consistent understanding of the mapping rules for beam-related information, the value of N1 may be set to Part1 when the first rule is predefined for the terminal; or, In the case that the first rule is predefined by the terminal and has not been negotiated with the network side device (that is, the network side device does not know the first rule), set the value of the N1 to the Part1; if the The first rule is predefined by the terminal, and the specific rules for determining the value of N1 have been negotiated with the network side device or notified to the network side device, then the value of N1 may not be mapped in the Part1; if the first rule is For network side device configuration, the value of N1 may not be mapped in Part1.

For example: the network side device configures the terminal: the relevant information of the beam pair with the highest measurement value of layer 1 is located in the first part; or, configures the proportion of N1 in N for the terminal, and configures only one proportion value, In the above situations, both the terminal and the network side device can know the specific rules for determining the value of N1, and there is no need to report the value of N1.

For example: the terminal defines the relevant information of the beam pair with the highest measured value in layer 1 in the first part; or the terminal defines the proportion of N1 in N, or the network side device configures multiple proportions for the terminal, but is determined by The terminal selects a ratio to determine the value of N1 according to the measurement situation; or the network-side device configures the first threshold, and the terminal determines the value of N1 based on the first threshold; in the above cases, the network-side device cannot directly determine N1 according to the preset rules value, the terminal can report the value of N1 in Part1.

The terminal can determine whether to report the value of N1 based on the above situation, and when it needs to report the value of N1, it can indicate by adding an indication field in Part1. Specifically, the first part includes a first indication field, and the first indication field indicates the value of N1. In this embodiment, a first indication field for indicating the value of N1 may be added to the first part, where the length of the first indication field may be log ₂ N bits.

Optionally, the terminal may also indicate the manner of determining the value of N1 in the first part. Specifically, the first part includes a second indication field, and the second indication field indicates how to determine the value of N1; or, the first indication field used to indicate the value of N1 in the first part indicates the Describe the way to determine the value of N1. Optionally, the terminal may directly indicate the determination method of the value of N1 through the first part, and may also use the indication field to implicitly indicate the determination method of the value of N1, for example: the second indication field or The first indication field is "0", indicating that the value of N1 is configured by the network side device through RRC, and the second indication field or the first indication field is "1", indicating that the value of N1 is The terminal is determined according to the first rule.

In this embodiment, the terminal may report the determining manner of the value of N1 through the first part. Specifically, a second indication field for indicating the manner of determining the value of N1 may be added in Part1, or the first indication field indicating the value of N1 may be multiplexed.

Wherein, when the terminal reports the relevant information of the N pairs of beams, the relevant information of the beams includes at least one of channel measurement resource indication and layer 1 measurement value. The channel measurement resource indication may include: CRI or SSBRI; the layer 1 measurement value may include: L1-RSRP or L1-SINR.

The manner in which the terminal reports the channel measurement resource indication and the layer 1 measurement value is respectively described below through specific embodiments.

As an optional embodiment, for Part1, information about the N1 pair of beams among the N pairs of beams is included, for example: the Part1 includes the channel measurement resource indication of the N1 pair of beams, and/or the layer 1 measurement of the N1 pair of beams value. The first part is also used to indicate the first correspondence between the channel measurement resource indications of the N1 pair of beams and the channel measurement resource set; wherein, the channel measurement resource indications of the N1 pair of beams are arranged according to the second rule. In this embodiment, the channel measurement resource indications of each pair of beams in the N1 pair of beams respectively correspond to different sets of channel measurement resources.

Wherein, the indication manner of the first corresponding relationship in the first part and the second rule of channel measurement resource indication arrangement may include but not limited to the following:

method one:

The first part indicates the first corresponding relationship between the channel measurement resource indication of the N1 pair of beams and the channel measurement resource set, which may include:

A first bit (may be log ₂ M) is added to the indication field of each channel measurement resource indication in the first part, and the first bit is used to indicate the correspondence between the channel measurement resource indication and the channel measurement resource set . That is, the extended channel measurement resource indication field is used to indicate the first correspondence.

Wherein, the second rule includes: the first channel measurement resource indication is arranged at the top of all channel measurement resource indications, and the first channel measurement resource indication is that the channel measurement resource with the highest measurement value in layer 1 is in the channel measurement resource to which it belongs. The index of the collection. The value of M may be the number of channel measurement resource sets configured by the network side device, and one channel measurement resource set corresponds to one TRP.

For example, the channel measurement resource indication is CRI or SSBRI, and the first corresponding relationship is indicated by extending the CRI/SSBRI indication field.

Assuming that the number of reported beam pairs configured by the network side device is N=2, and the UE judges the number of beam pairs reported in part 1 as N1=2 according to the measurement results, that is, all information related to the N pairs of beams is placed in part 1 for transmission , the structure schematic diagram of the CSI report including beam related information is shown in Fig. 3a and Fig. 3b. If the value of N1 is configured by RRC or determined by a preset rule and the network side device knows the value of N1, there is no need to report it, that is, the N1 part in Figure 3a is ignored.

As shown in Figure 3a and Figure 3b, the number of channel measurement resource sets (CMR sets) is 2, that is, the number of TRPs is 2, by extending the CRI/SSBRI indication field (CRI is used as an example in Figure 3a and Figure 3b), add 1 The bit indicates the CMR set corresponding to the CRI/SSBRI, for example, "0" indicates CMR set#0, that is, TRP#0, and "1" indicates CMR set#1, that is, TRP#1. The CRI ranked first is determined according to the corresponding layer 1 measurement value, CRI#1 with the largest layer 1 measurement value is ranked first, and the rest of the CRIs are arranged according to the preset beam pairing assumption. For example, in Figure 3a, front and rear pairing is performed according to the order of arrangement, that is, (CRI#1, CRI#2) is a beam pair that can be received by the UE, and is recorded as beam pair 1 (ie beam pair#1), (CRI#3, CRI #4) is another beam pair, denoted as beam pair 2 (beam pair #2); Figure 3b is the grouping of CRI in units of TRP, and the CRI at the same position in the two groups is the beam that can be received by the UE at the same time Yes, such as (CRI#1, CRI#3), (CRI#2, CRI#4). The permutation of SSBRI is the same as that of CRI, and will not be repeated here.

Optionally, for the value and sorting of the layer 1 measurement value, other measurement values except the largest layer 1 measurement value (ie, the first layer 1 measurement value) are differentially compared with the largest layer 1 measurement value The results are reported, and the order of layer 1 measurement values corresponds to the order of CRI/SSBRI. In Figure 3a and Figure 3b, the measured value of layer 1 is L1-RSRP, RSRP#1 is the largest measured value of layer 1, RSRP#2 and RSRP#1 are differentially mapped (ie Differential RSRP#2), RSRP#3 and RSRP#4 are similar . The L1-SINR is the same as it, and will not be repeated here.

Method 2:

A third indication field is added to the first part, and the third indication field is used to indicate: the first channel measurement resource indicates a first channel measurement resource set corresponding to the first channel measurement resource.

Wherein, the second rule includes: the first channel measurement resource indication is arranged at the top of all channel measurement resource indications, and other channel measurement resource indications except the first channel measurement resource indication are arranged according to the third rule; The first channel measurement resource indication is an index of a channel measurement resource with the highest layer 1 measurement value.

The third rule may include: taking the channel measurement resource indications associated with the same channel measurement resource set as a group and arranging them consecutively in units of the channel measurement resource set. That is, the channel measurement resource indications are arranged in units of channel measurement resource sets, and the channel measurement resource indications associated with the same channel measurement resource set are regarded as a group, and can be arranged continuously according to the predetermined rules of the network. The channel measurement resources at the same position in different groups The channel measurement resource corresponding to the resource indication can be simultaneously received by the UE.

Wherein, the channel measurement resource indication associated with the same channel measurement resource set as a set of continuous arrangement rules may be as follows: according to the layer 1 measurement value or the sum of beam pair measurement values in the measurement resource set 1, in descending order Sort the channel measurement resource indications in the channel measurement resource set 1, and sort the channel measurement resource indications in the remaining channel measurement resource sets according to the rule that the channel measurement resources corresponding to the channel measurement resource indications at the same position in different groups can be simultaneously received by the UE .

The third rule may also be: arranging all channel measurement resource indications according to beam pairs. That is, the channel measurement resource indications are arranged in the form of beam pairs. For example: the first channel measurement resource indication and the second channel measurement resource indication constitute a pair of beams that can be simultaneously received by the UE; the third channel measurement resource indication and the fourth channel measurement resource indication constitute a pair of beams that can be simultaneously received by the UE Yes, and the third channel measurement resource indication corresponds to the same channel measurement resource set as the first channel measurement resource indication, the fourth channel measurement resource indication corresponds to the same channel measurement resource set as the second channel measurement resource indication, and so on.

In this embodiment, a third indication field is added to the first part to indicate the first channel measurement resource set corresponding to the first channel measurement resource indication, and all channels can be determined according to the second rule and the third rule The arrangement sequence of the measurement resource indication and the channel measurement resource set determines the corresponding relationship between each channel measurement resource indication and the channel measurement resource set.

For example: a field is added to indicate the first channel measurement resource set to which the first channel measurement resource indication belongs.

Assume that the number of reported beam pairs configured by the network side device is N=2, and the UE judges that the number of beam pairs reported in part 1 is N1=2 according to the measurement results, that is, all beam related information is placed in part 1 for transmission, including beam A schematic diagram of the structure of the CSI report of relevant information can be shown in Figure 4a. If the value of N1 is configured by RRC or determined by a preset rule and the network side device knows the value of N1, there is no need to report it, that is, the N1 part in Figure 4a and Figure 4b is ignored. In this embodiment, the arrangement order of channel measurement resource indications is described in the following two cases.

(1) Arranging in units of beam pairs.

As shown in Figure 4a, the terminal places the channel measurement resource indication information of the first beam pair that includes the first channel measurement resource indication before the remaining channel measurement resource indications, and arranges the CRI information in the first beam pair according to network predefined rules For example, the first channel measurement resource (CRI#1) is ranked first in the channel measurement resource indication information of the first beam pair (beam pair#1). The corresponding relationship between the CRI and the channel measurement resource set in the first beam pair is indicated by a newly added indication field. For example, when the number of channel measurement resource sets (CMR sets) is 2, the newly added indicator field only needs 1 bit to indicate the corresponding relationship between CRI and CMR sets in the first beam pair, when the indicator field is 0 , indicating the first CRI in the first beam pair, that is, CRI#1, corresponding to CMR set (set) #0, and CRI#2 corresponding to CMR set#1; when the indication field is 1, the above situation is reversed, that is, The first CRI in the first beam pair, that is, CRI#2, corresponds to CMR set#1. The correspondence between CRI and CSI measurement resource sets in the remaining beam pairs is consistent with that in the first beam pair, that is, CRI#3 and CRI#1 correspond to the same CMR set, and CRI#4 and CRI#2 correspond to another CMR set. SSBRI is in the same order as CRI. The values and sorting of the measured values of layer 1 are the same as those shown in Fig. 3a and Fig. 3b in the first method above.

(2) Arranging in units of channel measurement resource sets.

As shown in Figure 4b, the terminal groups the reported beam-related information in units of channel measurement resource sets, and the CRIs in the same position in the group can be received by the terminal at the same time, such as (CRI#1, CRI#3), (CRI #2, CRI #4). For the arrangement order, the terminal puts the measurement resource indication information (such as CRI#1, CRI#2) of the CMR set containing the first channel measurement resource indication into the resource indication information (such as CRI#3, CRI# 4) before. In the first channel measurement resource set, the terminal arranges the order of the CRIs according to network predefined rules, for example, the first channel measurement resource indicator (CRI#1) is ranked first among the channel measurement resource indicators in the first channel measurement resource set. The identifier of the first channel measurement resource set is indicated by a newly added indication field. For example, when the number of channel measurement resource sets is 2, the newly added field only needs 1 bit to indicate the identifier of the first channel measurement resource set, and when the indication field is 0, it means that the first channel measurement resource set corresponds to CMR set#0, that is, all CRIs in the first channel measurement resource set correspond to CMR set#0; and all other CRIs correspond to CMR set#1. The above situation is reversed when the indicator field is 1. SSBRI and CRI are arranged in the same order. The values and sorting of the measured values of layer 1 are the same as the first method above, and will not be repeated here.

Method 3:

A fourth indication field is added to the first part, and the fourth indication field is used to indicate: the position indicated by the first channel measurement resource;

Wherein, the second rule includes: taking the channel measurement resource indications associated with the same channel measurement resource set as a group, and continuously arranging them in units of channel measurement resource sets, and the first channel measurement resource indication is arranged at the first A channel measurement resource indicates the top of the corresponding channel measurement resource set, and channel measurement resource indicators of different groups are arranged in a predetermined order; the first channel measurement resource indicator is the index of the channel measurement resource with the highest measurement value in layer 1.

In this embodiment, a fourth indication field is newly added in Part1 to indicate the position indicated by the first channel measurement resource with the highest measurement value of layer 1 . According to the channel measurement resource sets associated with each channel measurement resource indication, arrange the channel measurement resource indications associated with the same channel measurement resource set as a group of continuous arrangements, and arrange the first channel measurement resource indication in its corresponding channel measurement resource set before the rest of the channel measurement resources are indicated. The channel measurement resource indications of different groups are arranged in a predetermined order, and the channel measurement resources corresponding to the channel measurement resource indications at the same position in different groups can be received by UEs at the same time.

Wherein, the channel measurement resource indicators associated with the same channel measurement resource set are used as a set of continuous arrangement specific rules such as the second method, which will not be repeated here.

For example, assuming that there are two sets of channel measurement resources, the related information of 4 pairs of beams is reported, that is, each set includes 4 indications of channel measurement resources. Taking the channel measurement resource indication as CRI as an example, the predetermined sequence of CRIs in different groups is: the 4 CRIs of channel measurement resource set 1 are arranged first, and the 4 CRIs of channel measurement resource set 2 are arranged last.

In this case, the fourth indication field only needs 1 bit to indicate the position indicated by the first channel measurement resource. If the indication field is 0, it may indicate that the first channel measurement resource indication is at the top of channel measurement resource set 1, that is, at the top of all channel measurement resource indications; if the indication field is 1, it may indicate that the first channel measurement resource indication is at the channel measurement resource The first bit of set 2 is the fifth bit of all channel measurement resource indications. The channel measurement resource indications in the remaining channel measurement resource sets may be sorted according to the rule that the channel measurement resources corresponding to the channel measurement resource indications at the same position in different groups can be simultaneously received by the UE.

Method 4:

The first part indicates the first corresponding relationship between the channel measurement resource indication of the N1 pair of beams and the channel measurement resource set, which may include: using the channel measurement resource to indicate the arrangement position in the beam pair, and indicating the relationship between the channel measurement resource indication and the channel measurement resource set. The resource indicates the corresponding channel measurement resource set;

Wherein, the second rule includes: the channel measurement resource indications are arranged according to beam pairs, and the first beam pair is arranged first, and the channel measurement resource indications in each beam pair are arranged according to the fourth rule. The first beam pair is a beam pair including a first channel measurement resource indication, and the first channel measurement resource indication is an index of a channel measurement resource with the highest layer 1 measurement value.

The fourth rule may include: channel measurement resource indications associated with the same channel measurement resource set are located at the same position of different beam pairs.

In this embodiment, all channel measurement resource indications to be reported are arranged in the form of beam pairs and the first beam pair is arranged first, and the channel measurement resource indications in each beam pair can be arranged according to the fourth rule, for example, in The channel measurement resource indications at the same position in each beam pair correspond to the same channel measurement resource set. Wherein, the first beam pair is arranged at the first place, and the arrangement order of the remaining beam pairs except the first beam can be determined according to network pre-definition, for example: it can be based on the maximum layer 1 measurement value or layer 1 measurement value in each beam pair The sum of the values is sorted backwards in descending order.

Optionally, the method further includes: adding a fifth indication field to the first part, where the fifth indication field is used to indicate: the position of the first channel measurement resource indication in the first beam pair. In this embodiment, a fifth indication field may be added in Part1, which is used to indicate the position of the first channel measurement resource indication in the first beam pair.

For example: a field is added to indicate the position of the first channel measurement resource indication in the beam pair to which it belongs.

When the number of beam pairs reported by the network-side device is configured to be N=2, and the UE judges the number of beam pairs reported in part 1 to be N1=2 according to the measurement results, that is, all beam-related information is placed in part 1 for transmission, including beam A schematic structural diagram of a CSI report of related information can be shown in Figure 5a and Figure 5b. If the value of N1 is configured by RRC or determined by a preset rule and the network side device knows the value of N1, there is no need to report it, that is, part N1 in Figure 5a is ignored.

As shown in Figure 5a and Figure 5b, all CRIs are reported in the form of beam pairs, and the ordering of CRIs in each beam pair and the corresponding relationship with the CMR set are performed according to network preset rules. For example, the CRIs (CRI#1, CRI#3) associated with CMR set#0 are all in the first position of the CRI sequence in the beam pair, and the CRIs (CRI#2, CRI#4) associated with CMR set#1 are all in the beam pair Second position of the CRI sequence. In the beam pair arrangement, the terminal arranges the first beam pair information (CRI) including the first channel measurement resource indication at the top of all the beam pair information. Since the network side device can obtain other layer 1 measurement values only after knowing the maximum layer 1 measurement value, the terminal needs to inform the network side device of the CRI corresponding to the maximum layer 1 measurement value. Therefore, the network side device can be notified of the position of the first channel measurement resource indication in the first beam pair through the newly added indication field, so as to obtain the maximum layer 1 measurement value. As shown in Figure 5a, when the newly added indication field indication (Indication) is "0", the first channel measurement resource indication is CRI#1, and the maximum layer 1 measurement value is RSRP#1; as shown in Figure 5b, when When the newly added indication field indication (Indication) is "1", the first channel measurement resource indication is CRI#2, and the maximum layer 1 measurement value is RSRP#2. SSBRI is in the same order as CRI. The values and sorting of the measured values of layer 1 are the same as the first method above, and will not be repeated here.

The above-mentioned embodiments are all explained by reporting the related information of N pairs of beams in Part1. The implementation process of reporting the related information of N1 pair of beams in Part1 and the related information of N2 pair of beams in Part2 will be described below through specific embodiments.

Assume that N=3, N1=2, and N2=1, that is, the relevant information of two pairs of beams is reported in Part 1, and the relevant information of the other pair of beams is reported in Part 2. If the value of N1 is configured by RRC or determined by a preset rule and the network side device knows the value of N1, there is no need to report it, that is, the N1 part in Figure 6a and Figure 6b is ignored.

As shown in Figure 6a and Figure 6b, all CRIs are placed in Part 1 and Part 2 in the form of beam pairs for reporting, and the ordering of CRIs in each beam pair and their correspondence with CMR sets follow the network preset rules conduct. For example, the CRIs (CRI#1, CRI#3, CRI#5) associated with CMR set#0 are all at the top of the CRI sequence in the beam pair, and the CRIs associated with CMR set#1 (CRI#2, CRI#4, CRI# #6) are both in the second position of the CRI sequence in the beam pair. In the beam pair arrangement of Part 1, the terminal arranges the first beam pair information (CRI) including the first channel measurement resource indication at the top of all beam pair information. Since the network side device can obtain other layer 1 measurement values only after knowing the maximum layer 1 measurement value, the terminal needs to inform the network side device of the CRI corresponding to the maximum layer 1 measurement value. Therefore, the network side can be notified of the position of the first channel measurement resource indication in the first beam pair through the newly added indication field in Part 1, so as to obtain the maximum layer 1 measurement value. As shown in Figure 6a, when the newly added indication field indication (Indication) is "0", the first channel measurement resource indication is CRI#1, and the maximum layer 1 measurement value is RSRP#1; as shown in Figure 6b, when When the newly added indication field is "1", the first channel measurement resource indication is CRI#2, and the maximum measurement value is RSRP#2. SSBRI is in the same order as CRI. For the value selection and sorting of layer 1 measurement values in Part 1, it is the same as the above method 1, and will not be described here. The arrangement of CRI in Part 2 is consistent with that in Part 1, and the measured values of layer 1 are reported according to the difference value from the largest measured value of layer 1.

As another optional embodiment, for Part1, information related to an N1 pair of beams among the N pairs of beams is included, specifically: the first part includes layer 1 measurement values of the N1 pair of beams.

Specifically, the mapping of the N1 to the layer 1 measurement value of the beam in the first part may include one of the following:

Mode 1: Quantize the first layer 1 measurement value corresponding to the first channel measurement resource indication and place it in the first part; other channel measurement resource indications except the first channel measurement resource indication correspond to the layer 1 measurement value, The difference with the measured value of the first layer 1 is quantized and placed in the first part. That is: the first layer 1 measurement value corresponding to the first channel measurement resource indication is directly quantized and mapped to Part1, and the remaining layer 1 measurement values are differentiated from the first layer 1 measurement value and then quantized and mapped to Part1. Wherein, the specific arrangement sequence of the layer 1 measurement values corresponding to each channel measurement resource indication may correspond to the arrangement order of the channel measurement resource indication to which it belongs.

Method 2: Quantize all layer 1 measurement values in the first beam pair that includes the first channel measurement resource indication and place them in the first part; the layer 1 measurement values of other beam pairs except the first beam The layer 1 measurement value difference corresponding to the target channel measurement resource indication in the first beam pair is quantized and placed in the first part; the target channel measurement resource indication is: associated with the channel measurement resource indications in the other beam pairs Channel measurement resource indications of the same channel measurement resource set. That is: all layer 1 measurement values in the first beam pair including the first channel measurement resource indication are quantized and mapped to Part1, and the layer 1 measurement values of other beam pairs except the first beam are associated with the first beam pair The layer 1 measurement values of the same channel measurement resource set are differentiated and then quantized and mapped to Part1.

Method 3: Determine the second layer 1 measurement value in every n beam pairs according to the first predefined rule, quantize the second layer 1 measurement value and place it in the first part; divide the n beam pairs Differences between the measured values of the other layers 1 other than the measured values of the second layer 1 and the measured values of the second layer 1 are quantized and placed in the first part, N1>n≥1. The first predefined rule is, for example: the largest layer 1 measurement value in every 2 pairs of beams is determined as the second layer 1 measurement value, for example: a total of 4 pairs of beam pairs are reported related information, wherein every 2 pairs of beams determine A second layer 1 measurement value (which can be the largest measurement value), quantize the second layer 1 measurement value and directly map to Part1, and the remaining layer 1 measurement values can be quantized and mapped to Part1. Optionally, the second layer 1 measurement value may indicate a corresponding first layer 1 measurement value for the first channel measurement resource, that is, the measurement value is the largest.

Method 4: Determine the third layer 1 measurement value in every n beam pairs according to the second predefined rule, and quantify the difference between the third layer 1 measurement value and the first layer 1 measurement value corresponding to the first channel measurement resource indication After being placed in the first part; the remaining layer 1 measured values in the n beam pairs except the third layer 1 measured value and the third layer 1 measured value are quantized and placed in the first part, N1>n≥1. The second predefined rule is for example: the layer 1 measurement value in every 2 pairs of beams is determined from the largest to the smallest layer 1 measurement value in the second place as the third layer 1 measurement value, for example: a total of 4 pairs of beams are reported The relevant information of the beam pair, wherein a third layer 1 measurement value is determined in every 2 pairs of beams, and the difference between the third layer 1 measurement value and the first layer 1 measurement value corresponding to the first channel measurement resource indication is quantized and mapped to Part1, The other layer 1 measurement values may be quantified and mapped to Part1 after being differentiated from the third layer 1 measurement value. Optionally, the measured value of the third layer 1 may be the same as or different from the measured value of the second layer 1 . The measured value of the third layer 1 is smaller than the measured value of the first layer 1, for example: the measured value of the third layer 1 may be the measured value of the layer 1 ranked second in order of measured values.

It should be pointed out that, in the above several manners, the first channel measurement resource indication is the index of the channel measurement resource with the highest measurement value of layer 1; the order of arrangement of the measurement values of layer 1 in the first part is the same as 1 Corresponds to the arrangement sequence indicated by the channel measurement resource to which the measurement value belongs.

The above describes the mapping method of the relevant information of the N1 pair of beams in Part1 through the embodiment. When N1 is smaller than N, the relevant information of the N2 pair of beams other than the N1 pair of beams is mapped in Part2. The following is described through specific embodiments.

As an optional embodiment, the second part may include related information of the N2 pair of beams, such as a channel measurement resource indication of the N2 pair of beams, and/or a layer 1 measurement value of the N2 pair of beams. The second part is also used to indicate the second corresponding relationship between the channel measurement resource indication of the N2 pair of beams and the channel measurement resource set;

Wherein, the indication manner of the second correspondence in the second part may be the same as the indication manner of the first correspondence in the first part; the first correspondence is: the channel measurement of the N1 pair of beams The corresponding relationship between the resource indication and the channel measurement resource set.

In this embodiment, the indication manner of the second correspondence in Part2 is the same as the indication manner of the first correspondence in Part1. For example: extend the measurement resource indication field of Part2 to indicate the second correspondence; or add an indication field in Part2 to indicate that the channel measurement resource with the highest measurement value of layer 1 indicates the corresponding channel measurement resource set; or, in Part2 The newly added indication field indicates the position of the channel resource measurement indication with the highest measurement value at layer 1; or, the channel measurement resource set corresponding to the channel measurement resource indication is indicated through the arrangement position of the channel measurement resource indication in the beam pair. The arrangement rule and mapping manner of each channel measurement resource indication and channel measurement resource set are the same as the mapping of the first correspondence in the Part1, and will not be repeated here.

As an optional embodiment, the second part includes the relevant information of the N2 pair of beams may be: the second part includes the layer 1 measurement value of the N2 pair of beams;

Wherein, the mapping manner of the layer 1 measurement value of the N2 pair of beams in the second part may include one of the following:

(1) The mapping manner of the layer 1 measurement value of the N2 pair of beams in the second part is the same as the mapping manner of the layer 1 measurement value of the N1 pair of beams in the first part. That is, the mapping method of the layer 1 measurement value of N2 to the beam in Part2 is the same as the mapping method of the layer 1 measurement value of N1 to the beam in Part1, and details are not described here.

(2) According to the third predefined rule, the fourth layer 1 measurement value is determined in the N2 pair of beams, and the fourth layer 1 measurement value is quantized and placed in the second part, and the N2 pair of beams except Differences between the measured values of other layers 1 other than the measured values of layer 1 and the measured values of layer 1 are quantized and placed in the second part. The fourth layer 1 measurement may be the layer 1 measurement with the highest measurement. The third predefined rule is, for example: determining that the layer 1 measurement value with the largest measurement value in the N2 pair of beams is the fourth layer 1 measurement value.

(3) According to the fourth predefined rule, determine the fifth layer 1 measurement value in the N2 pair of beams, the fifth layer 1 measurement value indicates the first layer corresponding to the first channel resource in the first part After the differential quantization of the 1 measured value is placed in the second part, the remaining layer 1 measured values in the N2 pair of beams except the fifth layer 1 measured value and the fifth layer 1 measured value are placed after the differential quantization of the fifth layer 1 measured value the second part. The fourth predefined rule is for example: the measured value of the fifth layer 1 is smaller than the measured value of the first layer 1, and the measured value of the first layer 1 is the measured value of the layer 1 with the largest measured value, then the fifth The layer 1 measurement value can be the second layer 1 measurement value arranged in descending order of measurement values, the difference between the fifth layer 1 measurement value and the first layer 1 measurement value is quantified and mapped to Part2, and the remaining layer 1 measurement values After the difference with the measured value of the fifth layer 1, it is quantized and mapped to Part2.

Optionally, when the terminal sends a CSI report containing information about N pairs of beams to the network side device according to a preset rule, the information in the CSI report can be made available to the target according to the priority rule and the discarding rule uplink resource and send it to the network side device. That is, the preset rule includes the priority rule and the discarding rule.

In this embodiment, after the terminal generates the CSI report according to the relevant information of the N pairs of beams, according to the size of the available uplink resource, when the target available uplink resource carrying the CSI report cannot carry all the information of the target Part in the CSI report, according to The priority rule and the corresponding discarding rule discard part of the information content, so as to determine the content of the actually reported CSI report. Specifically, the priority rules include at least one of the following:

1) The priority of the related information of the beams in the beam pair is determined according to the ranking of the layer 1 measurement values, wherein the priority of the beam related information with the higher layer 1 measurement value is higher. Wherein, the priority of the related information of each beam inside the beam pair can be sorted according to the measured value of layer 1 from high to low, and the priority of the related information with high measured value of layer 1 is high.

2) The priorities of the related information of the beam pairs contained in the first part and the priorities of the related information of the beam pairs contained in the second part are respectively determined according to the arrangement of the measured values of layer 1, wherein the measured values of layer 1 are higher The priority of the related information of the beam pair is high. That is: the priorities of Part1 and the related information of each beam pair inside Part1 are arranged in descending order of the measurement values of layer 1, and the priority of the measurement values is higher.

3) The priority of the beam-related information included in the first part is higher than the priority of the beam-related information in the second part.

4) The priority among beam-related information included in the first part of different CSI reports is determined according to the fifth predefined rule; the fifth predefined rule is, for example, a priority calculation formula configured by the network side device.

5) The priority among beam-related information contained in the second part in different CSI reports is determined according to the sixth predefined rule. The sixth predefined rule is, for example: the network side device configures a priority calculation formula.

Optionally, the discarding rule may include one of the following:

a) Discard relevant information of all beams contained in the target part;

b) according to the priority of the beam pair in the target part, discard the relevant information of the beam pair with low priority in units of beam pairs;

c) according to the priorities of the beams contained in the beam pairs in the target part, discarding beam-related information with low priority in the beam pairs in units of beams;

Wherein, the target portion includes the first portion and/or the second portion.

It should be noted that, in the case that the target part includes the first part, the discarding rule further includes: discarding relevant information of all beams included in the second part. That is: if the information in Part1 needs to be discarded, all the information in Part2 also needs to be discarded.

It should be noted that the predefined rules in the embodiment of the present application can be configured by the network-side device, or can be determined by the terminal according to the reporting requirements of beam-related information. The content of the rules is not limited here.

In this embodiment, the CSI report containing information about the N pairs of beams is divided into two parts. The first part includes the channel measurement resource indication and/or layer 1 measurement value of the N1 pair of beams, and may also include the arrangement order of the N1 pair of beams and the channel The corresponding relationship between the measurement resource indication and the channel measurement resource set; the second part includes the relevant information of the N2 pair of beams, the arrangement order of the N2 pair of beams, and the corresponding relationship between the channel measurement resource indication and the channel measurement resource set. After the CSI report is determined, the CSI report is mapped to the target uplink available resource according to the priority rule and sent to the network side device. A variety of ways are designed to indicate the reporting channel measurement resource indication and its corresponding layer 1 measurement value, the corresponding relationship between the channel measurement resource indication and the TRP (that is, the corresponding relationship between the channel measurement resource indication and the channel measurement resource set), so that the network side device according to The CSI report can know the TRP corresponding to the reported beam-related information, avoiding wrong scheduling of network-side devices. This embodiment determines the priority and discarding rules of beam-related information, which can reduce UCI fixed bit overhead and improve terminal scheduling flexibility.

In the embodiment of the present application, when the terminal reports beam-related information, it can put the related information of N pairs of beams in the CSI report according to the preset rules and report it, which realizes the flexible configuration of beam-related information reporting and can reduce the number of beam-related information carried. The fixed bit overhead of the UCI ensures the reliable reporting of beam-related information and effectively avoids the loss of high-priority beam information caused by a large UCI fixed load.

It should be noted that, the beam reporting method provided in the embodiment of the present application may be executed by a beam reporting device, or a control module in the beam reporting device for executing the beam reporting method. In the embodiment of the present application, the method for reporting the beam performed by the device for reporting the beam is used as an example to describe the device for reporting the beam provided in the embodiment of the present application.
