Description

Measurement reporting method and device

The present application claims priority of chinese patent application with application number 202110363857.X, filed by the chinese patent office on 04/02/2021, entitled "a measurement reporting method and apparatus", which is incorporated herein by reference in its entirety.

Technical Field

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

Background

Currently, when a network side device deploys multiple TRPs (TRansmission points) and a terminal has multiple receiving antenna arrays (panels), the terminal may receive signals of the multiple TRPs at the same time, that is, may receive signals having multiple different QCL-type D (Quasi-Co-Location type D) parameters at the same time.

However, in the prior art, neither group-based beam reporting nor group-based beam reporting is clear to a terminal from which TRP a CSI-RS (Channel State Indication Reference Signal) in a CSI (Channel State information) measurement set is coming, and thus 2 or at most 4 beams reported may be sent by the same TRP or different TRPs. For example, in a TRP transmission scenario, beams reported by a terminal according to the maximum L1-RSRP (Layer-1 Reference Signal receiving Power) may be from the same TRP, that is, measurement results suitable for single TRP transmission, that is, effective measurement results cannot be provided for multiple TRP transmissions.

As can be seen, in the prior art, no consideration is given to measurement reporting in a multi-TRP multi-panel scenario, that is, a method for reporting beam measurement in a multi-TRP scenario is urgently needed.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The embodiments and features of the embodiments of the present invention may be arbitrarily combined with each other without conflict. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

For a better understanding of the present solution, some of the processes and terms involved are described below:

1. the terminal equipment:

the terminal device according to the embodiments of the present invention may be a device providing voice and/or data connectivity to a user, a handheld device having a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the names of the terminal devices may be different, for example, in a 5G system, the terminal device may be called a User Equipment (UE). A wireless terminal device, which may be a mobile terminal device such as a mobile phone (or called a "cellular" phone) and a computer having a mobile terminal device, for example, a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device, may communicate with one or more Core Networks (CNs) via a Radio Access Network (RAN), and may exchange languages and/or data with the RAN. Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, session Initiation Protocol (SIP) phones, wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). The wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an access point (access point), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), and a user device (user device), which are not limited in the embodiments of the present invention.

2. The network side equipment:

the network side device related to the embodiment of the present invention may be a base station, and the base station may include a plurality of cells for providing services for the terminal. A base station may also be referred to as an access point, or a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or by other names, depending on the particular application. The network-side device may be configured to exchange the received air frame with an Internet Protocol (IP) packet as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network side device may also coordinate attribute management for the air interface. For example, the network side device according to the embodiment of the present invention may be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) or a Code Division Multiple Access (CDMA), may be a network side device (NodeB) in a Wideband Code Division Multiple Access (WCDMA), may be a evolved Node B (eNB or e-NodeB) in a Long Term Evolution (LTE) System, may be a 5G Base Station (gNB) in a 5G network architecture (next generation System), may be a Home evolved Node B (Home evolved Node B, heNB), a relay Node (relay Node), a Home Base Station (femto), a pico Base Station (pico) and the like, and is not limited in the embodiments of the present invention. In some network structures, the network side device may include a Centralized Unit (CU) node and a Distributed Unit (DU) node, and the centralized unit and the distributed unit may be geographically separated.

Specifically, one or more antennas may be used between the network-side device and the terminal device to perform Multiple-Input Multiple-Output (MIMO) transmission, where the MIMO transmission may be Single User MIMO (SU-MIMO) or Multi-User MIMO (MU-MIMO). The MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or may be diversity transmission, precoding transmission, beamforming transmission, or the like, depending on the form and number of root antenna combinations.

3. And the CSI reporting process comprises the following steps:

in the existing protocol, a network side device may configure a CSI Resource set (CSI Resource Setting, a set of channel state information resources) for a terminal, and a corresponding higher-level parameter of the CSI Resource set may be represented as CSI-ResourceConfig; and a CSI Reporting set (Reporting Setting), wherein the corresponding high-level parameters can be expressed as CSI-Reporting configuration for measuring and Reporting the CSI. Each CSI reporting set is associated with at most 3 CSI resource sets, and one report Quantity (report Quantity) is configured to indicate content reported by the terminal. Specifically, the reported quantity comprises L1-RSRP (Layer-1 Reference Signal receiving Power), which corresponds to a high-level parameter of 'cri-RSRP' or 'ssb-Index-RSRP'; and, L1-SINR (Layer-1 Signal to Interference plus Noise Ratio, layer 1 Signal to Interference plus Noise Ratio), which corresponds to the higher Layer parameter 'cri-SINR' or 'ssb-Index-SINR'); and CQI (Channel Quality Indication), PMI (Precoding Matrix Indicator), RI (Rank Indication), CRI (CSI reference Signal Resource Indication), SSBRI (Synchronization Signal Block Resource Indication), etc., or a combination thereof.

The terminal device may measure the CSI resource set associated with the CSI report set, and report the CSI resource set according to the report amount configured in the CSI report set.

4. And (3) beam reporting:

the L1-RSRP and the L1-SINR are reporting parameters aiming at the beam quality in the beam management process, and the CSI reporting process is adopted in the reporting process.

Further, the network side device may further configure the terminal to perform group-based beam reporting (group-based beam reporting) and non-group-based beam reporting (non-group-based beam reporting). That is, the CSI reporting set configuration (CSI-report configuration) includes a parameter groupbasedbeamrreporting, specifically, the number of reported beams is configurable, that is, the parameter nrofReportedRS, and the number of reported beams is at most 4.

However, as described above, in the prior art, no consideration is given to measurement reporting in a scenario with multiple TRPs and multiple panels. For example, in existing group-based beam reporting and non-group-based beam reporting, the terminal is not aware of which TRP the CSI-RS in the CSI measurement set is from, and thus 2 or at most 4 beams reported may be transmitted by the same TRP, or different TRPs. For example, in a TRP transmission scenario, a beam reported by a terminal according to the maximum L1-RSRP may always be from the same TRP, that is, a side result when a single TRP is transmitted is suitable, that is, an effective measurement result cannot be provided for multiple TRP transmissions.

In view of this, the present invention provides a measurement reporting method, by which a beam measurement reporting method in a multi-TRP scenario can be implemented, so that a terminal can report a measurement result that is beneficial for simultaneous transmission of multiple TRPs.

Referring to fig. 1, fig. 1 is a flowchart illustrating a measurement reporting method according to an embodiment of the present invention.

Step 101: and according to the configuration of the network side equipment, determining quasi co-location type QCL-TypeD parameters of each CSI-RS group when the CSI-RS group is used for measurement and a measurement set when the CSI-RS group is used for measurement.

In the embodiment of the present invention, the network side device may configure one CSI resource set for the terminal, or configure two CSI resource sets for the terminal, so that the terminal may determine, based on the configuration of the network side device, a quasi co-located type QCL-type parameter used for measurement and a measurement set used for measurement of each CSI-RS set.

It should be noted that, in all embodiments of the present invention, a CSI resource set (i.e., CSI resource setting) may configure a plurality of CSI-RS resource sets (i.e., CSI resource sets), where each CSI-RS resource set is a CSI-RS resource set. Or one CSI-RS resource set can be configured, one CSI-RS resource set is configured with a plurality of CSI-RS resource subsets, and each CSI-RS resource subset is one CSI-RS resource set; or, one CSI-RS resource set may configure one CSI-RS resource set, where one CSI-RS resource set includes multiple CSI-RS resources, and the multiple CSI-RS resources are implicitly divided into multiple CSI-RS resource sets by a higher layer signaling parameter or a group index or a physical cell ID.

For convenience of description, the CSI-RS resource group is hereinafter described as an example. In an actual implementation process, the measurement reporting method provided by the present solution may be expressed based on the CSI resource set or the CSI resource set, which is not limited in the present invention. In addition, it should be noted that, in the embodiment of the present invention, the CSI-RS group may be understood as a CSI-RS resource group.

The CSI-RS resources in all embodiments of the present invention may also be replaced by SSB resources, that is, CSI resource setting or CSI resource set includes a case where the resource is SSB (Synchronization Signal Block).

In the embodiment of the present invention, the terminal determines, according to the configuration of the network side device, a measurement set used for measurement in each CSI-RS group, and may adopt, but is not limited to, any of the following manners:

mode 1:

in an exemplary embodiment, if a network side device configures one CSI resource set, and one CSI resource set includes K CSI-RS groups; when measuring the layer 1 signal-to-interference-plus-noise ratio L1-SINR of the mth CSI-RS group, determining that the mth CSI-RS group is used for channel measurement and other CSI-RS groups except the mth CSI-RS group are used for interference measurement. Wherein m is any value from 0 to K; k is a positive integer not less than 1; the CSI-RS groups for channel measurements and for interference measurements belong to a measurement set.

For example, if K is 4, when L1-SINR of the 2 nd CSI-RS group is measured, it may be determined that the 2 nd CSI-RS group is used for channel measurement, and CSI-RS groups other than the 2 nd CSI-RS group, that is, the 1 st CSI-RS group, the 3 rd CSI-RS group, and the 4 th CSI-RS group, of the 4 CSI-RS groups are used for interference measurement.

Wherein m is any value from 0 to K; k is a positive integer not less than 1, and CSI-RS groups used for channel measurement and interference measurement belong to a measurement set.

Mode 6:

in an exemplary embodiment, if the network side device configures two CSI resource sets, and each CSI resource set includes K CSI-RS groups; and determining the first CSI-RS group of each CSI resource set to be used for channel measurement, and using the CSI-RS groups except the first CSI-RS group for interference measurement. Wherein m is any value from 0 to K; k is a positive integer not less than 1, and CSI-RS groups used for channel measurement and interference measurement belong to a measurement set.

It can be seen that, in the embodiment of the present invention, the measurement set may include only CSI-RS sets for channel measurement, may also include CSI-RS sets for interference measurement, and may also include CSI-RS sets for channel measurement and for interference measurement at the same time.

In the embodiment of the present invention, the terminal determines, according to the configuration of the network side device, a quasi co-located type QCL-type parameter when each channel state indication reference signal CSI-RS group is used for measurement, and may adopt, but is not limited to, any of the following manners:

mode 1:

in the embodiment of the invention, if a piece of CSI-RS resource set is configured by a network side device, and it can be determined that the CSI-RS resource set includes K CSI-RS groups, and one or more QCL-type parameters are configured for a CSI-RS resource in each CSI-RS group, where K is a positive integer not less than 1, and Z is a positive integer not less than 1, a first QCL-type parameter configured for each CSI-RS resource can be determined, and the first QCL-type parameter is a QCL-type parameter when the CSI-RS group of the CSI-RS resource or the CSI-RS resource is used for channel measurement; and the QCL-TypeD parameters except the first QCL-TypeD parameter are QCL-TypeD parameters when the CSI-RS resources are used for interference measurement. That is, the terminal may assume the QCL of the CSI-RS resource as the sum of all the configured QCL-typeD parameters or the union of all the QCL-typeD parameters when measuring the CSI-RS resource.

in an exemplary embodiment, if the network side device configures one CSI resource set, and one CSI resource set includes K CSI-RS groups, and each CSI-RS group includes Z CSI-RS resources, and the CSI-RS resource in each CSI-RS group configures one QCL-type parameter; the QCL-type parameter configured for each CSI-RS resource can be determined as the QCL-type parameter when the CSI-RS resource or the CSI-RS group where the CSI-RS resource is located is used for channel measurement; and the QCL-TypeD parameters configured by the CSI-RS resources corresponding to the other CSI-RS groups except the group where the CSI-RS resource is located in the K CSI-RS groups are used as QCL-TypeD parameters when the CSI-RS resources are used for interference measurement.

Mode 3:

in an exemplary embodiment, if a network side device configures one CSI resource set, and one CSI resource set includes K CSI-RS groups, and each CSI-RS group includes Z CSI-RS resources, and the CSI-RS resource in each CSI-RS group configures one QCL-type parameter; when the mth CSI-RS group is measured, configuring a union of the QCL-Typed parameters of the pth CSI-RS resource of the mth CSI-RS group and the QCL-Typed parameters configured by the CSI-RS resources corresponding to the CSI-RS groups except the mth CSI-RS group for the pth CSI-RS resource; p is any value between 0 and Z, and Z is a positive integer not less than 1.

It should be noted that, in this embodiment, the QCL-type parameter of the p-th CSI-RS resource of the m-th CSI-RS group may be a parameter used for channel measurement or a parameter used for interference measurement, and is not limited in this embodiment.

Mode 4:

It should be noted that, in this embodiment, the QCL-type parameter configured for the CSI-RS resource may be a QCL-type parameter used for channel measurement or a QCL-type parameter used for interference measurement, which is not limited in this embodiment.

Mode 5:

Wherein m is any value from 0 to K; k is a positive integer not less than 1.

For example, assuming that K is 4, the CSI-RS groups corresponding to the first CSI resource set are the CSI-RS group A1, the CSI-RS group A2, the CSI-RS group A3, and the CSI-RS group A4, respectively, and the CSI-RS groups corresponding to the second CSI resource set are the CSI-RS group B1, the CSI-RS group B2, the CSI-RS group B3, and the CSI-RS group B4, respectively, it may be determined that, when the second CSI-RS group B3 is measured, the QCL-typeD parameter of the CSI-RS group A3 is used as the QCL-typeD parameter thereof.

Mode 6:

in an exemplary embodiment, if the network side device configures two CSI resource sets, and each CSI resource set includes K CSI-RS groups; when measuring the CSI-RS resources in the mth CSI-RS group of each CSI resource set, taking the QCL-typeD parameters of the corresponding CSI-RS resources in the 1 st CSI-RS group of each CSI resource set as the QCL-typeD parameters of the CSI-RS resources in the mth CSI-RS group; wherein m is any value from 0 to K; k is a positive integer not less than 1.

It should be noted that, in this embodiment, the QCL-type parameter of the CSI-RS resource corresponding to the 1 st CSI-RS group of each CSI resource set may be used as the QCL-type parameter for channel measurement of the CSI-RS resource corresponding to the 1 st CSI-RS group of each CSI resource set, or may be used as the QCL-type parameter for interference measurement of the CSI-RS resource corresponding to the 1 st CSI-RS group of each CSI resource set, which is not limited in this embodiment.

In the embodiment of the invention, when the CSI-RS group is a CSI-RS group explicitly configured by the network side equipment, the corresponding CSI-RS resource is 2 CSI-RS resources with the same sequence value or relative index value or the same index value in the two CSI resource set configurations.

In the embodiment of the invention, when the CSI-RS group is the CSI-RS resource implicit group, the corresponding CSI-RS resources are 2 CSI-RS resources with the same sequence value after the CSI-RS resources in the two CSI-RS resource implicit groups are sequenced from low to high according to the index values; wherein the CSI-RS resource implicit group is a CSI-RS resource implicitly grouped and determined based on a higher layer parameter or a group index or a physical cell ID contained in each CSI-RS resource.

In the embodiment of the present invention, the mth CSI-RS set in the foregoing embodiment may be determined by, but is not limited to, any of the following manners:

(1) And the mth CSI-RS group is determined from small to large based on the configuration sequence or the index of the CSI resource set in the CSI resource set.

(2) And the mth CSI-RS group is determined according to the order of the index values of the CSI-RS resources from small to large.

(3) And determining the mth CSI-RS group from small to large according to the sequence of the configuration values of the high-level parameters related to the CSI-RS resources.

(4) And the mth CSI-RS group is determined according to the order of the indexes of the CSI-RS resources with the smallest indexes in each CSI-RS group from small to large.

It can be seen that, in the embodiment of the present invention, the mth CSI-RS group may be determined in various ways, which provides various embodiments and enhances the implementability of the scheme provided by the present invention.

Step 102: measuring the measurement set based on the QCL-TypeD parameter, and determining N groups of measurement report values; n is a positive integer not less than 1.

In the embodiment of the invention, the CSI-RS resource can be received according to the determined QCL-type parameter, the measured value of the layer 1 reference signal received power L1-RSRP or the layer 1 signal-to-interference-plus-noise ratio L1-SINR is determined, and then the CSI-RS resource indication CRI or the synchronous signal block resource indication SSBRI contained in the N groups of measurement report values is determined according to the L1-RSRP or the L1-SINR.

In the embodiment of the invention, the high-to-low ranking is carried out according to the L1-RSRP or L1-SINR measurement values of K CSI-RS groups corresponding to the CSI-RS resources, and the CRI or the SSBRI contained in any measurement report value in the N groups is determined.

For example, the reported 1 st group of CRI/SSBRI corresponds to the CSI-RS resource with the maximum L1-RSRP or L1-SINR value in each CSI-RS group; and the reported CRI/SSBRI of the 2 nd group is the CSI-RS resource with the second largest L1-RSRP or L1-SINR value in each CSI-RS group, and the like, so that the reported N groups of measurement values are determined.

In a specific implementation process, the z-th group CRI/SSBRI reported by the terminal is a CSI-RS resource with the largest z-size L1-RSRP value in each CSI-RS group. And the value of z is any value from 0 to N, and the terminal selects a wave beam with the maximum L1-RSRP value from the implicit group or the set of K CSI-RS resources respectively as a1 st group measurement report value (CSI-RS resource). Then, respectively selecting beams with the second largest L1-RSRP values, namely CSI-RS resources from the K CSI-RS resource implicit groups or CSI resource sets as 2 nd group measurement results; and the rest is repeated until the Nth beam (CSI-RS resource) with the L1-RSRP value is selected from the K CSI-RS resource implicit groups or the CSI resource sets respectively to serve as the Nth group measurement result. The m (K =1,2, …, K) th measurement value of each set of measurements is from the m (K =1,2, …, K) th CSI-RS resource implicit group or CSI resource set. If one CSI-RS resource is associated with multiple implicit CSI-RS resource groups or CSI resource sets, for example, the kth CSI-RS resource implicit group or CSI resource set and the kth CSI-RS resource implicit group or CSI resource set, the measurement result corresponding to the CSI-RS resource may appear at the kth 1 and kth 2 positions of each group of measurement results when reporting. The reporting method in the method can also be called reporting among groups.

In the embodiment of the invention, the L1-RSRP or L1-SINR reported values included in a single CSI-RS group corresponding to the CSI-RS resource can be ranked, and the CRI or the SSBRI contained in any one of the N groups of measurement reported values is determined based on the maximum L1-RSRP or L1-SINR value in each CSI-RS group.

For example, the reported 1 st group CRI/SSBRI is a CSI-RS resource with the maximum L1-RSRP or L1-SINR value in a certain CSI-RS group; and the reported 2 nd group CRI/SSBRI is a CSI-RS resource with a second largest L1-RSRP or L1-SINR value in a certain CSI-RS group, and the rest is done in sequence, so that the reported N groups of measurement report values are determined.

As can be seen, in the embodiment of the present disclosure, CSI-RS resources corresponding to all maximum L1-RSRP or L1-SINR values in the K groups may be used as a group of measurement report values, that is, the measurement report values are determined by using an inter-group reporting mode; the CSI-RS resource corresponding to the maximum L1-RSRP or L1-SINR value in any one of the K groups may also be used as a group of measurement report values, that is, the measurement report values are determined in an intra-group reporting manner. Obviously, the embodiment of the present invention provides specific implementation manners of an intra-group reporting manner and an inter-group reporting manner, thereby enhancing the implementability of the scheme.

In a specific implementation process, the reported CRI/SSBRI of the z-th group is a CSI-RS resource having a first M-th larger L1-RSRP value in the z-th CSI-RS group, N belongs to any value of 0-N, for example, when N = K, the first group report value corresponds to a first CSI-RS resource implicit group or CSI resource set configured on the network device side, that is, the CRI/SSBRI corresponding to M CSI-RS resources having a larger L1-SINR value in the CSI-RS group; the second group of report values correspond to CRI/SSBRI corresponding to M CSI-RS resources with larger L1-SINR values in a second CSI-RS group configured at the network equipment side; and repeating the steps until the CRI/SSBRI corresponding to M CSI-RS resources with larger L1-SINR values in the Nth CSI-RS group configured by the network equipment side and corresponding to the Nth group report value is determined. When N is less than K, the terminal can also select N groups with relatively large L1-RSRP values to report. For example, the N groups are selected according to the largest L1-SINR ordering in the group, or the N groups are selected according to the Mth largest L1-RSRP ordering in each group. The reporting method in the method can also be called reporting in a group. In this case, N < = K and M < = P need to be calculated. Wherein P is a positive integer not less than 1.

In the embodiment of the invention, N groups of measurement report values can be determined according to the indication information of the network side equipment; specifically, if it is determined that the indication information indicates that the terminal determines to report the measurement value in the CSI-RS group, the N groups of measurement report values include CRI or SSBRI included in each group of measurement report values determined based on sorting of L1-RSRP or L1-SINR report values included in K CSI-RS groups corresponding to the CSI-RS resource from high to low.

Specifically, if the indication information indicates that the terminal determines to report the measurement value among the CSI-RS groups, the N groups of measurement report values include L1-RSRP or L1-SINR report values that are included in a single CSI-RS group corresponding to the CSI-RS resource and are sorted, and the CRI or SSBRI included in each group of measurement report values that is determined is based on the maximum L1-RSRP or L1-SINR value in each CSI-RS group.

Optionally, when the network side device does not configure or instruct the terminal to perform intra-group reporting or inter-group reporting, the terminal reports by default using the inter-group measurement value, that is, reports according to the foregoing. Optionally, the terminal may indicate that the reporting is performed as intra-group reporting or inter-group reporting when reporting.

In the embodiment of the invention, the terminal can also determine the CSI-RS resource pair meeting the condition firstly, so as to determine N groups of measurement report values in the determined CSI-RS resource pair. Optionally, this step may also be performed before step 101. In the embodiment of the present invention, the CSI-RS resource pair satisfying the condition may be determined in, but not limited to, the following manners:

mode A:

in the embodiment of the present invention, the terminal may determine, according to a predefined rule, that resources in different CSI-RS resource groups may be received simultaneously; alternatively, resources within the same set of CSI-RS resources may be received simultaneously to determine a set of pairs of CSI-RS resources that may be received simultaneously.

Mode B:

in the embodiment of the invention, the terminal can determine the incidence relation between each QCL-TypeD parameter and the terminal receiving spatial filter; wherein the association relationship is determined by the terminal based on the previous measurement result, and when 2 CSI-RS resources are simultaneously received using different antenna arrays or antenna groups and an expected measurement result determined based on the QCL-type parameter of the two CSI-RS resources and the association relationship is obtained when the two CSI-RS resources are received, it may be determined that the two CSI-RS resources may be simultaneously received, and thus, a set of pairs of CSI-RS resources that may be simultaneously received may be determined.

Mode C:

in the embodiment of the invention, when the network side equipment configures the terminal to perform the inter-group report or the terminal does not receive the configuration of the network side equipment, the inter-group report is determined, and the terminal selects specific CSI-RS resources which can be received simultaneously among K CSI-RS resource groups respectively; or, when the network side device configures the terminal for reporting in the group, the terminal selects a specific CSI-RS resource that can be received simultaneously in each CSI-RS resource group to determine a set of CSI-RS resource pairs that can be received simultaneously.

For example, assume that a first implicit CSI-RS resource group or CSI-RS resource set includes beams, i.e., CSI-RS resources) is [ a1, a2, …, a4]; the second implicit set of CSI-RS resources or set of CSI resources contains beams (CSI-RS resources) of [ b1, b2, …, b4].

If the terminal determines to perform the inter-group reporting, it is determined according to the terminal implementation or the configuration of the network side device that the inter-group beam pairs that can be received at the same time are: [ a1, b1], [ a1, b2], [ a2, b1], [ a3, b3], [ a3, b4], [ a4, b2] and [ a4, b4]. Specifically, if it is determined according to a predefined rule that any two inter-group beam pairs can be received simultaneously, that is, at most 4 × 4=16 beam pairs. In addition, it can also be considered that [ ai, bj ] and [ bj, ai ] are different beam pairs, and then the value of the beam pair that the terminal can simultaneously receive at this time is 2 times of the above-determined value.

If the terminal determines to perform the intra-group reporting, it is determined that the pair of intra-group beams that can be simultaneously received is [ a1, a3], [ a1, a4], [ a2, a3], [ a2, a4], [ a3, a4], [ a4, a1], [ b1, b4] and [ b2, b4] according to the implementation of the terminal or the configuration of the network side device. If it is determined according to predefined rules that any 2 intra-group beam pairs can be received simultaneously, or that any 2 intra-group beam pairs cannot be received simultaneously, i.e. 0 pairs. Further, [ ai, aj ] and [ aj, ai ] may also be considered as different beam pairs, [ bi, bj ] and [ bj, bi ] as different beam pairs.

In the embodiment of the present invention, after determining the set of CSI-RS resource pairs that can be received simultaneously, a beam pair, that is, a CSI-RS resource pair, included in the report may be determined based on the set of CSI-RS resource pairs that can be received simultaneously, so that N groups or N pairs of reported beam pairs are not completely the same.

In one possible implementation, the terminal may determine a CSI-RS resource of an s-th layer 1 reference signal received power L1-RSRP in the set of CSI-RS resource pairs that may be simultaneously received as a first measurement report value of an s-th set of measurement report values; and determining the CSI-RS resource of the s-th L1-RSRP in the set of the CSI-RS resource pairs which can be simultaneously received with the first CSI-RS resource as the second measurement report value in the s-th group of measurement report values.

Specifically, the first measurement report value and the second measurement report value in each s-th group in the set of CSI-RS resource pairs that can be received simultaneously may be used as N groups of measurement report values; wherein s is a sequence number determined based on the value size of L1-RSRP.

In a specific implementation process, a sequence number determined for the value of L1-RSRP may be used, where the value of L1-RSRP may be a CSI-RS resource of L1-RSRP values on CSI-RS resources in all CSI-RS resource implicit groups or CSI-RS resource sets, or may be limited to a L1-RSRP value on a CSI-RS resource in a first CSI-RS resource implicit group or CSI-RS resource set, which is not limited in the embodiment of the present invention. Specifically, the sequence number with the largest value of L1-RSRP may be determined as 1, the sequence number with the second largest value of L1-RSRP may be determined as 2, and so on, the sequence number corresponding to the value of L1-RSRP may be determined.

It can be seen that, when s is 1, the first set of measurement report values is the CSI-RS resource corresponding to the maximum value of L1-RSRP. That is, the terminal determines that the first CSI-RS resource of the first set of measurement report values is the beam with the largest L1-RSRP in the set of CSI-RS resource pairs that can be received simultaneously, the second CSI-RS resource is the beam with the largest L1-RSRP in the CSI-RS that can be received simultaneously with the first CSI-RS resource, and deletes the CSI-RS resource pair in the set of CSI-RS resource pairs that can be received simultaneously after determining the first set of measurement report values. Specifically, when determining the second set of measurement report values, the method used is the same as the method used for determining the first set of measurement report values, but the second set of measurement report values determined and reported by the first set of CSI-RS resource pairs, which are updated later and can be received at the same time, is deleted, and so on, so that the measurement report values can be determined.

In a possible implementation manner, sequential values determined from high to low corresponding to the sum of L1-RSRPs of two CSI-RSs in one CSI-RS resource pair in the set of CSI-RS resource pairs that can be received simultaneously can also be determined. Then determining each group of measurement reported values corresponding to the sequence values one by one according to the sequence values, and determining N groups of measurement reported values based on the measurement reported values corresponding to all CSI-RS resource pairs; wherein T is a positive integer less than N. Specifically, the terminal selects a CSI-RS resource pair with the largest sum of L1-RSRPs of 2 CSI-RSs in one CSI-RS resource pair as a first group of measurement report values in a set S (S is a CSI-RS resource pair satisfying a condition), selects a CSI-RS resource pair with a second largest sum of L1-RSRPs of 2 CSI-RSs in one CSI-RS resource pair as a second group of measurement report values in the set S, and so on until N groups of measurement report pairs are selected.

It can be seen that, in the embodiment of the present invention, in order to reduce the feedback overhead, when the determined CSI resource pair is [ bj, ai ], the CSI resource pair may also be adjusted to [ ai, bj ] during actual reporting. That is, the first CSI-RS resource is from a CSI resource set with a smaller CSI-RS resource implicit group index value or higher layer parameter value, or with a smaller CSI resource set index.

That is to say, it can be ensured that N CSI-RS resource pairs, i.e., measurement report values, reported by the terminal are not completely the same, so that more beam information can be provided in one report, and the feedback overhead is reduced.

In the embodiment of the present invention, after the N groups of measurement report values are determined, a difference value corresponding to the N groups of measurement values may be determined according to the N groups of measurement report values, a report format of the N groups of measurement report values is determined based on the difference value, and the N groups of measurement report values are reported to the network side device by using the report format.

In the embodiment of the present invention, after N groups of measurement report values are determined, a difference value corresponding to the N groups of measurement values may be determined, and a report format of the N groups of measurement report values is determined to be an intra-group difference format or an inter-group difference format according to the difference value.

In the embodiment of the present invention, the following may be adopted, but not limited to, to determine the difference corresponding to the N sets of measurement values:

mode 1:

in an exemplary embodiment, 2 nd to w th measurement report values included in each of the N sets of measurement report values are determined to be differences from a first measurement report value in the set, and w is a positive integer not less than 2.

Mode 2:

in an exemplary embodiment, a first group of measurement report values in the N groups of measurement report values are determined to be L1-RSRP values or L1-SINR values obtained through measurement; a difference between an r-th measurement report value of the measurement report values in the q-th group other than the first group of measurement report values and an r-th measurement report value of the first group of measurement report values; r is any value from 0 to w.

Mode 3:

in an exemplary embodiment, a first measurement report value in a first group of the N groups of measurement report values is determined to be a measured L1-RSRP value or L1-SINR value, a measurement report value in the first group except the first measurement report value, and a difference value between the measurement report value in the first group except the first measurement report value and the first measurement report value in the first group; wherein r is any value from 0 to w.

Mode 4:

in an exemplary embodiment, a first measurement report value in a first group of the N groups of measurement report values is determined to be a measured L1-RSRP value or L1-SINR value, and other measurement report values except the first measurement report value in the first group are determined to be a difference value with the first measurement report value in the first group of measurement report values; wherein r is any value from 0 to w.

In the embodiment of the present invention, the N sets of measurement report values may be reported to the network side device in an intra-group differential report format or an inter-group report format through a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH).

In a specific implementation process, it is assumed that the measurement report values reported by the terminal are 4 groups, and each group includes 2 measurement values, that is, 8L 1-RSRP values reported by the terminal are RSRP #1, RSRP #2, RSRP #3, RSRP #4, RSRP #5, RSRP #6, RSRP #7, and RSRP #8, respectively; similarly, in the L1-SINR report, the 8 report values are SINR #1, SINR #2, SINR #3, SINR #4, SINR #5, SINR #6, SINR #7, SINR #8, respectively.

Specifically, in the differential reporting, one or more (for example, the largest one or more) measurement values are directly reported, that is, the one or more measurement values are directly reported, and may be called non-differential measurement values, while other measurement values except the non-differential measurement values are differentially reported, and may be called differential measurement values. Specifically, the directly reported measurement value is quantized by using a bit, and the differential measurement value is quantized by using b bit. For example a =7,b =4.

However, in one reporting, if the position where the directly reported measurement value, i.e. the non-differential measurement value, and the differentially reported measurement value, i.e. the differential measurement value, appear is not fixed, the base station will not be able to correctly interpret each measurement value.

For example, assuming that RSRP #1 is quantized by 7 bits, other RSRPs are quantized by 4 bits, and CRI/SSBRI have 32 bits in total, the terminal reports 67 bits in one report, and the base station may determine that the first 32 bits represent CRI/SSBRI after receiving UCI (uplink control information) reported by the terminal, for example, each CRI/SSBRI has 4 bits, 8 CRI/SSBRI in total, RSRP #1,40-43 bits corresponding to RSRP #2, …, and so on. If the measured value of the RSRP #2 is the largest in a certain report, and the report mode of direct report is adopted, and the other measured values adopt the mode of differential report, the base station still receives 67 bits, the interpretation is performed according to the method of Rel-15, that is, the first 32 bits represent CRI/SSBRI, the 33 th to 39 th bits correspond to RSRP #1,40-43 bits correspond to RSRP #2, … and the like, so that the RSRP #1 and RSRP #2 are interpreted wrongly.

Based on the foregoing problems, in the embodiment of the present invention, when reporting N sets of measurement report values to a network side device in a differential reporting manner, for example, in an intra-group differential reporting format or an inter-group reporting format, the N sets of measurement values are reported to the network side device, and a corresponding design is provided for the reporting manner, so that a base station can correctly interpret uplink control information, and further accurately obtain the N sets of measurement report values.

In the embodiment of the present invention, differential reporting may be performed in the following manner, but is not limited to:

mode 1:

in the embodiment of the invention, when the reporting format is intra-group difference and N groups of measurement reporting values are reported, a preset T bit added in uplink control information UCI indicates the position of a non-difference measurement value in one group; the non-differential measurement is used to characterize a maximum measurement within a group.

Optionally, if it is determined that the reporting format is intra-group difference, it is determined that the measured values outside the ith measured value of each of the N groups of measurement reporting values are all differentiated from the ith measured value in the group, and i is a positive integer greater than or equal to 1.

Specifically, M measurement values in each of N sets of measurement report values respectively correspond to K CSI-RS resource sets, and when M = K, the M measurement values in each set correspond to the K CSI-RS resource sets one by one.

In the embodiment of the present invention, when reporting N groups of measurement report values, a preset T bit that can be added to UCI indicates a position where a non-differential measurement value in one group appears.

Specifically, T of the preset T bit is determined based on the following formula:

wherein N is used for representing the number of groups of measurement reported values, M is used for representing the number of measurement reported values in each group,

operators for characterizing the ceiling operation.

For example, when N =4,m =2, T may be determined to be 4, i.e., 4 bits are added to the uplink control information, each bit indicating a position where a non-differential measurement value within one group occurs. For example, 1 and 0 indicate that a non-differential measurement appears on the 1 st or 2 nd measurement within the group, respectively. For another example, when N =4,m =4, T may be determined to be 8, that is, 8 bits are added to the uplink control information, and each 2 bits corresponds to an occurrence position of a non-differential measurement value in one group, that is, one code point (00,01,10 or 11) corresponds to one occurrence position.

In this embodiment of the present invention, the position of the increased T bit may be after, before, or before the CRI/SSBRI and/or the L1-RSRP/L1-SINR, or before or after the CRI reported by each group, or before or after the L1-RSRP/L1-SINR reported by each group, which is not limited in this embodiment of the present invention.

For example, when N =4,m =2, the bit of the increased T appears before CRI/SSBRI and/or L1-RSRP, the format reported is referred to table 1:

TABLE 1

Where numbers #1 and #2 are the first group, #3 and #4 are the second group, #5 and #6 are the third group, and #7 and #8 are the fourth group, each bit indicating where the differential measurement values within one group occur. For example, if the differential measurement value occurrence position is indicated as 0110, then the second measurement value in the first group, the first measurement value in the second group, the first measurement value in the third group, and the second measurement value in the fourth group can be determined as differential measurement values, i.e., corresponding to RSRP #2, RSRP #3, RSRP #5, RSRP #8.

Mode 2:

in the embodiment of the present invention, when reporting N groups of measurement report values, a preset T bit added in uplink control information UCI indicates a position where a differential measurement value in a group appears, where T is determined correspondingly based on the number of groups of measurement report values and the number of measurement report values in each group.

Optionally, when determining that the j-th measurement value (except the i-th group) of each of the N groups of measurement report values is different from the j-th measurement value of the i-th group, wherein j =1,2, …, M; i =1,2, …, N.

In embodiments of the present invention, T may be determined based on the following formula: .

operators for characterizing the ceiling operation.

Similar to the method in the mode 1, increase

The bit indicates where the differential measurement occurred, and the added bit may occur after CRI/SSBRI and/or L1-RSRP/L1-SINR. For example, when N =2,m =2, it may be determined that the first preset number is 2, that is, 2 bits are added, and the two bits respectively represent which group the 1 st measurement value and the 2 nd measurement value are differentiated for. Further, when it is determined that 2 bits are added, and if one bit of the 2 bits is 0 and the other bit is 1, the bit of 0 indicates that a difference is made for the first group, and the bit of 1 indicates that a difference is made for the second group; when the 2 bits are all 0, it means that the first measured value of each group is differentiated with respect to the first measured value of the first group, and the 2 nd measured value of each group is differentiated with respect to the 2 nd measured value of the first group.

For another example, when N =4, m =2, it may be determined that the first preset number is 4, that is, 4 bits are added, and the bits also represent groups for which the 1 st and 2 nd measured values are differentiated respectively, for example, the differential position of one measured value is represented by every 2 bits. If 4 bits are 0110, respectively, it may be determined that 01 indicates that the first measurement is differentiated for group 2 and 10 indicates that the second measurement is differentiated for group 3.

Mode 3:

in the embodiment of the invention, when the report format is the difference between groups, when N groups of measurement report values are reported, T bits added in uplink control information UCI indicate the position of the difference measurement value; the differential measurements are used to characterize the measurements within a group except for the largest measurement.

Specifically, the inter-group difference is that the measured values except the first measured value of the first group and the measured values except the first group are all differentiated from the 1 st measured value of the first group. And the difference mode between groups can be further expanded as follows: the measurements other than the first measurement of the first group, and the measurements other than the first group, are each differentiated from the 2 nd measurement of the first group.

For example, if T is 1, it indicates that the 2 nd measurement value for the first group is differentiated when the bit is 0, and indicates that the 1 st measurement value for the first group is differentiated when the bit is 1.

It should be noted that, in the implementation of the above mode 1, mode 2, and mode 3, each set of measurement report values and CSI-RS resource groups have a fixed association relationship, that is, when L1-RSRP reports, a plurality of L1-RSRP values are always arranged in a fixed order, for example, when N =4, m =2, RSRP #1, RSRP #2, RSRP #3, RSRP #4, RSRP #5, RSRP #6, RSRP #7, and RSRP #8 respectively correspond to 1,2,1,2,1,2,1,2 CSI-RS resource groups, and similarly, CRI/SSBRI or L1-SINR is also arranged in a fixed order.

Mode 4:

in the embodiment of the invention, when the reporting format is intra-group difference or inter-group difference, and when reporting N groups of measurement reporting values, a preset number of bits added in uplink control information UCI indicate the association relationship between the measurement values and the CSI-RS resource group; or, the indication unit is used for indicating whether the corresponding CSI-RS resource groups are permuted.

For example, the predetermined number of bits may be determined based on the manner of determining T bits, for example, when N =4, m =2, then the second predetermined number may be determined to be 8, and specifically, the association relationship between each measurement value or CRI/SSBRI and 2 CSI-RS resource groups (e.g., CSI resource sets) may be indicated in a bit mapping (bitmap) manner, such as 0 for a first CSI-RS resource group and 1 for a second CSI-RS resource group. For example, for intra-group difference, 01100110 indicates that 8 reported measurement values respectively correspond to the 1 st, 2 nd, 1 st, 2 nd, and 1 st CSI-RS resource groups.

Still taking N =4,m =2 as an example, when intra-group differentiation is employed, 1 bit may be employed per group to indicate whether the measurement values of the group are permuted, such as '1' indicating the order is permuted and '0' indicating the order is not permuted. For example, originally, each set of 2 measurement values respectively corresponds to a first CSI-RS resource set and a second CSI-RS resource set, if the swapping order is indicated, it indicates that the first measurement value is the second CSI-RS resource set at present, and the second measurement value corresponds to the first CSI-RS resource set. In this case, the L1-RSRP or L1-SINR within the group are always arranged in descending order.

Specifically, for the inter-group difference, 1 bit can also be used to indicate whether the 2 measurement values of the first group are in order-switched, and the method is similar to the intra-group difference, and since the other groups are the differential measurement values for one measurement value of the first group, no order switching is needed, so that this way, no order switching situation needs to be indicated for the other groups.

In an actual implementation process, please refer to table 2, where table 2 shows a UCI overhead comparison of multiple reporting methods, where K denotes the number of CSI-RS resources or SSB resources in each CSI-RS resource group, and one CSI-RS resource group may be one CSI resource set.

TABLE 2

As can be seen from table 2, after reporting based on a group beam in a multi-TRP scenario is supported, a UCI load is significantly increased compared to that in the prior art, and therefore, the embodiment of the present invention further provides a scheme for reducing an uplink control information load.

In the embodiment of the present invention, it may be determined that each differential measurement value or the reporting bit number of each measurement value in the N sets of measurement values is reported, and then the N sets of measurement values may be reported to the network side device based on the reporting bit number and the preset reporting rule.

Optionally, saving L1-RSRP or L1-SINR overhead may be considered to reduce UCI load. Illustratively, each differential measurement value is reported with lower overhead, that is, the current 4 bits can be reduced to 0,1,2 or 3 bits, that is, the number of reporting bits for reporting each differential measurement value in the N sets of measurement values can be 0,1,2 or 3 bits. Specifically, the number of reporting bits for reporting each differential measurement value in the N sets of measurement values is reduced to several bits, which may be predefined in a protocol, configured by a high-level signaling, or determined by a terminal, which is not limited in the embodiment of the present invention.

Illustratively, the differential measurement values are reported by using 0 bit, that is, only the direct measurement values are reported when reporting, and the differential measurement values are not reported, that is, the number of reported bits of each differential measurement value in the N sets of measurement values is reduced to 0 bit. That is, when N =4,m =2, when intra-group differencing is adopted, one beam (a beam reported in a differencing manner) in each group reports only the CRI/SSBRI, and does not report the corresponding L1-RSRP or L1-SINR.

Illustratively, the differential measurement values are reported using 1 bit. That is, only the direct measurement value is reported during reporting, and the differential measurement value is only reported for 1 measurement value, that is, the number of reported bits of each differential measurement value in the N sets of measurement values is reduced to 1 bit. When the intra-group difference is adopted, each group of beams (CRI/SSBRI) from 2 to M, or the beams with the values of L1-RSRP or L1-SINR from 2 to M are larger, the corresponding L1-RSRP or L1-SINR is reported by using a coarser granularity (such as 1 bit), if the difference between the second beam and the first beam is within XdB, the second beam is 1, otherwise, the difference is 0; the reverse is also possible, for example, with a gap of XdB, a second beam of 0, and otherwise 1.

Thus, compared with the prior differential reporting mode, the measurement value corresponding to each differential beam can reduce 3-bit overhead. In addition, X may be a predefined value in the protocol, such as 8dB, or may be a value configured by RRC signaling, which is not limited in the embodiment of the present invention.

Illustratively, the differential measurement values are reported by 2 or 3 bits, that is, the number of reported bits for reporting each differential measurement value in the N sets of measurement values is reduced to 2 or 3 bits. At this point Y difference values, or threshold values, may be configured or predefined, and if the difference measurement falls into which interval the corresponding value is reported.

For example, the reporting bit number of each differential measurement value in the N sets of measurement values is 2, 2 difference values are defined as Y1 and Y2, see table 3, and table 3 is a reporting value determined by the reporting bit number of each differential measurement value in the N sets of measurement values being 2.

TABLE 3

For another example, the reporting bit number of each differential measurement value in the N sets of measurement values is still 2 bits, and 3 differential measurement values are defined as Y1, Y2, and Y3, referring to table 4, where table 4 is a report value determined corresponding to the reporting bit number of each differential measurement value in the N sets of measurement values being reported being 3.

TABLE 4

For another example, reporting the number of reported bits of each differential measurement value in the N sets of measurement values is 3 bits, and it can be defined that at most 7 difference values (or thresholds) are Y1, Y2, Y3, Y4, Y5, Y6, and Y7, respectively, referring to table 5, where table 5 is a reported value determined corresponding to the number of reported bits of each differential measurement value in the N sets of measurement values being 3.

TABLE 5

Optionally, reducing the overhead of CRI/SSBRI may also be considered to reduce the load of UCI. For example, when the gap of 2 beams is greater than ZdB, only the first CRI is reported, otherwise, 2 CRIs are reported. Z may be a predefined value in the protocol, such as 8dB, or may be a value configured by RRC signaling, which is not limited in the embodiment of the present invention. When the difference is too large, it indicates that the quality of the beams reported in the difference form is poor, and the service cannot be provided for the terminal, so that the corresponding CRI/SSBRI may not be reported. Similarly, the corresponding L1-RSRP or L1-SINR may not be reported.

For the convenience of understanding of the technical solutions reported in the measurement, several possible ways are listed below to describe the technical solutions reported in the measurement, and it should be understood that the following examples are only illustrative and do not limit the embodiments of the present invention, and other ways may be adopted in the specific implementation process besides the ways listed below, which are not exhaustive herein.

The first embodiment is as follows:

in this embodiment, if the network side device configures one CSI resource set for the terminal, and the CSI resource set includes a plurality of CSI resource sets, each CSI-RS resource set includes a plurality of CSI-RS resource groups, and each CSI resource set corresponds to 1 TRP. That is to say, the first embodiment takes one CSI reporting setting, that is, one CSI reporting set and one CSI resource set as an example for explanation.

In one possible implementation, the CSI resource set may include a plurality of CSI-RS resources, each CSI-RS resource includes, when configured, an upper layer parameter related to its corresponding TRP, for example, the CSI-RS resource includes an upper layer parameter coresetpoilndex, or a group index, or other upper layer parameters, or a physical cell index (physical cell ID).

It should be noted that the high-level parameter has at most K values, that is, the CSI-RS resources are implicitly divided into K groups, and each group includes P CSI-RS resources. For example, the value of K is, for example, 2, representing 2 TRPs. At this time, the K implicit sets of CSI-RS resources may be included in one CSI resource set. Under the implicit grouping, two or more TRP-related higher-layer parameters are configured in one CSI-RS resource, for example, 2 group indexes are configured, or 2 or more values of one higher-layer parameter are included, for example, the CORESETPoolIndex values are 0 and 1. That is, such a representation may indicate that one CSI-RS resource is associated with 2 or more TRPs, e.g., both TRP1 and TRP2 transmit reference signals on this CSI-RS resource. Optionally, 2 or more QCL-type parameters may be configured for this CSI-RS resource.

In addition, it should be noted that, in all embodiments of the present invention, it may be assumed that the number of CSI-RS resources per group is equal, which is only for convenience of description, that is, the method in the present invention may also be extended to a case where the number of CSI-RS resources per group is not equal.

In the embodiment of the present invention, if the network side device configures the terminal to perform L1-RSRP measurement reporting, the terminal may determine the measurement reporting behavior of the terminal according to the following method:

step a: the terminal determines QCL-TypeD parameters on each CSI-RS resource according to the configuration of network side equipment, receives the CSI-RS according to the determined QCL-TypeD parameters, and measures and determines the receiving power of each CSI-RS to determine the value of L1-RSRP.

In the embodiment of the invention, when measuring the L1-RSRP value corresponding to each CSI-RS resource, the terminal can use each CSI-RS resource group for channel measurement, so that the CSI-RS resource can be received directly according to the QCL-type parameter configured for each CSI-RS resource in the CSI-RS group for channel measurement in advance by the network side equipment, and the receiving power of each CSI-RS can be measured and determined to determine the L1-RSRP value.

In this embodiment of the present invention, the CSI resource sets further include explicit groupings of other CSI-RSs, where a specific display grouping is, for example, that one CSI resource set explicitly configures 2 CSI resource sets, or that one CSI resource set includes 2 CSI resource subsets (i.e., resource subsets), or that one CSI resource set includes 2 CSI resource subsets (i.e., CSI resource subsets), and so on, which is not limited in this embodiment of the present invention.

In this embodiment, when measuring the L1-RSRP value corresponding to each CSI-RS resource, the terminal uses each CSI-RS resource implicit group or CSI resource set for channel measurement.

Step b: and the terminal determines the CRI or the SSBRI contained in the N groups of measurement report values.

In the embodiment of the present invention, after the terminal determines the L1-RSRP value, the CRI or SSBRI included in the N sets of measurement report values may be determined based on the L1-RSRP value.

Specifically, the mode for determining the measurement report value may refer to the inter-group report mode and the intra-group report mode described in step 102 to determine the measurement report value, which is not described herein again.

In a specific implementation process, if one CSI-RS resource is associated with multiple CSI-RS resource implicit groups or CSI resource sets, for example, the 1 st and 2 nd CSI-RS resource implicit groups or CSI resource sets, the measurement results corresponding to the CSI-RS resource may appear at the 1 st and 2 nd positions of each group of measurement results when reporting.

Step c: and the terminal determines the L1-RSRP measurement value corresponding to the CRI or the SSBRI in the N groups of measurement report values.

In the embodiment of the invention, after determining which beams (CRI or SSBRI) corresponding to the L1-RSRP need to be reported through the steps a and b, the measured values are quantitatively reported. Wherein, part of the measured values adopt a direct quantization reporting mode, and the other measured values adopt differential quantization with other unquantized measured values to report.

It can be determined from the reported N groups of measured values that the measured values from 2 nd to w th in each group are all the differences from the first measured value in the group, where w is a positive integer not less than 2.

In a possible implementation manner, in the reported N groups of measurement values, a first group of measurement report values in the N groups of measurement report values is determined to be a measured L1-RSRP value or L1-SINR value; a difference between an r-th reported value of the qth set of measured reported values, excluding the first set of measured reported values, and an r-th measured reported value of the first set of measured reported values. It can be seen that if the inter-group reporting method is adopted, it can be understood that a difference is performed between multiple beams reported by each TRP.

In a possible implementation manner, in the N groups of reported measured values, it is determined that a first measurement report value in a first group of the N groups of measurement report values is a measured L1-RSRP value or L1-SINR value, a reported value of the first group except the first measurement report value, and a reported value except the first group is a difference value from a1 st reported value of the first group of measurement report values; wherein r is any value from 0 to w.

In a possible implementation manner, a first measurement report value in a first group of the N groups of measurement report values is determined to be a measured L1-RSRP value or L1-SINR value, and other report values except the first measurement report value in the first group are determined to be a difference value with a1 st measurement report value of the first group of measurement report values; wherein r is any value from 0 to w.

Step d: and the terminal reports the L1-RSRP measurement value corresponding to the CRI or the SSBRI in the N groups of measurement report values to the network side equipment through the PUCCH or PUSCH.

It should be noted that, in the embodiment of the present invention, if the network side device configures the terminal to perform L1-SINR measurement reporting, the L1-RSPR in all the steps above may be replaced with L1-SINR.

Example two:

in this embodiment, the configuration of the CSI reporting set and the CSI resource set is the same as that in embodiment 1, that is, the network side device configures 1 CSI reporting set for the terminal, where the CSI reporting set corresponds to 1 CSI resource set. The CSI resource set comprises K CSI resource sets, namely K CSI-RS groups, each CSI resource set comprises P CSI-RS resources, each CSI resource set corresponds to 1 TRP, namely the channel or the interference sent by the corresponding TRP or used for the terminal to measure the corresponding TRP. Or, the CSI resource set includes K × P CSI-RS resources, each CSI-RS resource has one TRP-related higher-level parameter when configured, for example, the CSI-RS resource includes a higher-level parameter coresetpoilndex, or a group index, or other higher-level parameters, and the value of the higher-level parameter has at most K values, that is, the CSI-RS resources are implicitly divided into K groups, and each group of P CSI-RS resources. A typical value for K is, for example, 2, representing 2 TRPs. Under the implicit grouping, two or more TRP-related higher-layer parameters are configured in one CSI-RS resource, for example, 2 group indexes are configured, or 2 or more values of one higher-layer parameter are included, for example, the CORESETPoolIndex values are 0 and 1. In this case, one CSI-RS resource and 2 or more TRP associations are indicated, e.g., both TRP1 and TRP2 transmit reference signals on this CSI-RS resource. Optionally, 2 or more QCL-type parameters may be configured for this CSI-RS resource.

In the embodiment, the L1-SINR reported by the terminal uses each CSI-RS resource implicit group or CSI resource set for channel measurement and interference measurement. I.e. one implicit set of CSI-RS resources or CSI resource set, may be used for both channel measurements and interference measurements. The interference situation measured at this time is the set of interferences experienced by the terminal, i.e. all interferences. The present embodiment presents a measurement method of measuring a specific interference (e.g., inter-cell or inter-TRP interference). It should be noted that, in the embodiment of the present invention, one CSI-RS resource implicit group or CSI resource set is simply referred to as one CSI-RS group.

Referring to fig. 2, fig. 2 illustrates an example in which a CSI-RS group 1 and a CSI-RS group 2 are respectively associated with a TRP1 and a TRP2, that is, the TRP1 transmits a reference signal on a CSI-RS resource in the CSI-RS group 1, and the TRP2 transmits a signal on a CSI-RS resource in the CSI-RS group 2.

In a specific implementation process, the TRP1 may generate interference on the terminal to receive a signal on the TRP2 while transmitting a reference signal on the CSI-RS resource in the CSI-RS group 1, and similarly, the TRP2 may generate interference on the terminal to receive a signal on the TRP1 while transmitting a reference signal on the CSI-RS resource in the CSI-RS group 2. Therefore, when performing L1-SINR measurement, the terminal can perform channel measurement of TRP1 and interference measurement of TRP2 according to CSI-RS group 1; and performing channel measurement of the TRP2 and interference measurement of the TRP1 according to the CSI-RS group 2.

In this embodiment, the specific measurement reporting method includes:

step f: and the terminal determines a QCL-TypeD parameter on each CSI-RS resource according to the configuration of the network side equipment, receives the CSI-RS according to the determined QCL-TypeD parameter, and measures and determines the receiving power of each CSI-RS so as to determine the value of L1-SINR.

Specifically, the L1-SINR value may be determined in, but not limited to, the following two ways:

the first method is as follows:

in this embodiment, taking K =2 as an example, the network side device configures 2 QCL-type parameters for each CSI-RS resource in the CSI-RS group 1 and the CSI-RS group 2, where a first QCL-type parameter is assumed to represent a QCL of the CSI-RS resource when used for channel measurement, and a second QCL-type parameter is assumed to represent a QCL of the CSI-RS resource when used for interference measurement.

In a specific implementation process, the terminal may use the CSI-RS set 1 for channel measurement and the CSI-RS set 2 for interference measurement, where the interference of the TRP2 on the TRP1 may be measured. Specifically, it is assumed that the number of CSI-RS resources in CSI-RS group 1 and the number of CSI-RS resources in CSI-RS group 2 are equal.

It should be noted that, in all embodiments of the present invention, the CSI-RS resource includes NZP (Non-zero Power CSI-RS resource and SSB (Synchronization Signal Block).

In a specific implementation process, for one CSI-RS resource in the CSI-RS group 1, during measurement, the terminal may use a first QCL-type configured by the network side device on the CSI-RS resource to receive and measure the CSI-RS resource as a channel measurement value (for example, labeled as M1) of a TRP corresponding to the first CSI-RS group. Meanwhile, the second QCL-type parameter configured by the network side device may be used to receive and measure the CSI-RS resource as an interference measurement value (e.g., labeled as M2) of the TRP corresponding to the second CSI-RS group.

In a specific implementation process, the same or similar manner is adopted for one corresponding CSI-RS resource in the CSI-RS group 2, that is, the CSI-RS resource corresponding to the measured CSI-RS resource in the CSI-RS group 1. During measurement, the terminal receives and measures the CSI-RS resource as a channel measurement value (for example, marked as M3) of the TRP corresponding to the second CSI-RS group by using the first QCL-type configured by the network side device on the CSI-RS resource. Meanwhile, the second QCL-type parameter configured by the network side device is used to receive and measure the CSI-RS resource as an interference measurement value (for example, mark M4) of the TRP corresponding to the first CSI-RS group.

In this embodiment, when the terminal measures the L1-SINR value on the TRP corresponding to the first CSI-RS group, using the measured values M1 and M4, in order to determine the interference situation more accurately based on M4, it may be assumed that the QCL-type parameters when measuring the channel and measuring the interference are the same, that is, the second QCL-type parameter of the CSI-RS in the CSI-RS group 2 and the first QCL-type parameter of the CSI-RS corresponding to the CSI-RS in the CSI-RS group 1 are configured to be the same value.

Specifically, in the same manner, when the terminal measures the L1-SINR value on the TRP corresponding to the second CSI-RS group, using the measured values M3 and M2, in order to determine the interference situation more accurately based on M2, it may be assumed that the QCL-type parameters of the measured channel and the measured interference are the same, that is, the second QCL-type parameter of one CSI-RS in the CSI-RS group 1 and the first QCL-type parameter of the corresponding CSI-RS in the CSI-RS group 2 are configured to be the same value.

It should be noted that, in all embodiments of the present invention, when performing L1-SINR measurement, if a CSI-RS group is a CSI resource set or an explicitly configured CSI-RS group, a corresponding CSI-RS resource refers to 2 CSI-RS resources having the same sequence value in 2 CSI resource set configurations. For example, the 4 th CSI-RS resource configured in the first CSI-RS resource set and the 4 th CSI-RS resource configured in the second CSI-RS resource set correspond. Specifically, if the CSI-RS group is an implicit CSI-RS resource group, the corresponding CSI-RS resources refer to 2 CSI-RS resources having the same sequence value after the CSI-RS resources in the 2 implicit groups are sorted from low to high according to the index value. The 2 CSI-RS resource implicit groups refer to 2 CSI-RS resource implicit groups in the same CSI resource set, or 2 CSI-RS resource implicit groups in different CSI resource sets.

The second method comprises the following steps:

also taking K =2 as an example, the network side device configures 1 QCL-type parameter for each CSI-RS resource in the CSI-RS group 1 and the CSI-RS group 2, and when measuring each CSI-RS resource, the terminal uses the QCL-type parameter configured by the network side device to perform channel measurement, and uses one predefined QCL-type parameter to perform interference measurement.

In this embodiment, the terminal may use the CSI-RS group 1 for channel measurement and the CSI-RS group 2 for interference measurement, so that the interference of the TRP2 on the TRP1 may be measured. Specifically, it is assumed that the number of CSI-RS resources in CSI-RS group 1 and the number of CSI-RS resources in CSI-RS group 2 are equal.

In this embodiment, for one CSI-RS resource in the CSI-RS group 1, during measurement, the terminal uses the QCL-type configured by the network device on the resource to receive and measure the CSI-RS resource, as one channel measurement value (for example, marked as M1) of the TRP corresponding to the first CSI-RS group. At the same time, the QCL-type parameter of the corresponding CSI-RS resource configuration in CSI-RS group 2 is used to receive a measurement of the CSI-RS resource as an interference measurement value (e.g., labeled M2) of the TRP corresponding to the second CSI-RS group.

Specifically, in the same manner, the CSI-RS resources corresponding to the CSI-RS resources measured in the CSI-RS group 1 are targeted to the corresponding CSI-RS resources in the CSI-RS group 2. During measurement, the terminal receives and measures the CSI-RS resource as a channel measurement value (for example, marked as M3) of the TRP corresponding to the second CSI-RS group by using the QCL-type configured by the network side device on the resource. At the same time, the QCL-type parameter of the corresponding CSI-RS resource configuration in CSI-RS group 1 is used to receive and measure the CSI-RS resource as an interference measurement value (e.g., labeled M4) of the TRP corresponding to the first CSI-RS group.

Specifically, when the terminal is measuring the L1-SINR value on the TRP corresponding to the CSI-RS group 1, the L1-SINR value is jointly determined by using the measured values M1 and M4. And when the terminal measures the L1-SINR value on the TRP corresponding to the CSI-RS group 2, the L1-SINR value is jointly determined by using the measured values M3 and M2.

In this embodiment, the network side device may further configure or indicate some assumptions or restrictions of the terminal during measurement, for example, receive 2 CSI-RS resource implicit groups or CSI resource sets or CSI-RS resources using the same or different fronts panel; or receiving 2 implicit sets of CSI-RS resources or CSI-RS resources using the same or different spatial reception filters; or instruct the terminal to perform the superposition processing or the interference processing on the CSI-RS group 2 when measuring the CSI-RS group 1, and similarly, instruct the terminal to perform the superposition processing or the interference processing on the CSI-RS group 1 when measuring the CSI-RS group 2.

Under the condition that the network side equipment is configured or not configured with the assumptions or the limitations, the terminal can report the measurement assumptions or the limitations simultaneously when reporting the measurement result.

Step g: and the terminal determines the CRI or the SSBRI contained in the N groups of measurement report values.

In this embodiment, the terminal determines the CRI or SSBRI included in the reported N groups of measurement values according to the method in step b in the first embodiment, which is not described herein again.

Step h: and the terminal determines the L1-RSRP measurement value corresponding to the CRI or the SSBRI in the N groups of measurement report values.

In this embodiment, the terminal determines the measurement value according to the manner of determining the difference in step c in the first embodiment, specifically, the L1-RSRP in step c in the first embodiment may be replaced by L1-SINR for processing, which is not described herein again.

Step i: and the terminal reports the L1-RSRP measurement value corresponding to the CRI or the SSBRI in the N groups of measurement report values to the network side equipment through the PUCCH or PUSCH.

Example three:

in this embodiment, a measurement reporting implementation process in which a network side device configures one reporting set for a terminal, and one reporting set corresponds to two CSI resource sets, and a reported measurement value is L1-SINR is described as an example.

In this embodiment, a network side device configures 1 CSI reporting set for a terminal, where the CSI reporting set corresponds to 2 CSI resource sets, and each CSI resource set includes K CSI-RS groups (explicit groups or implicit groups) and is only used for reporting L1-SINR.

In this embodiment, a first CSI-RS group (e.g., labeled as CSI-RS group 1) in the first CSI resource set is used for channel measurement of one TRP (e.g., labeled as TRP 1), and a second CSI-RS group (e.g., labeled as CSI-RS group 2) is used for channel measurement of another TRP (e.g., labeled as TRP 2). And a first CSI-RS group (e.g., labeled as CSI-RS group 1) in the second set of CSI resources is used for interference measurement of TRP1, and a second CSI-RS group (e.g., labeled as CSI-RS group 2) is used for interference measurement of TRP 2. For measuring inter-TRP interference, it may be assumed that the first and second CSI-RS groups in the second CSI resource set are the second and first CSI-RS groups in the first CSI resource set g, respectively.

In this embodiment, the method for reporting measurement specifically includes:

step m: and the terminal determines a QCL-TypeD parameter on each CSI-RS resource according to the configuration of the network side equipment, receives the CSI-RS according to the determined QCL-TypeD parameter, and measures and determines the receiving power of each CSI-RS so as to determine the L1-SINR value.

In this embodiment, for one CSI-RS resource in the CSI-RS group 1 in the first CSI resource set, during measurement, the terminal uses the QCL-type configured by the network side device on the CSI-RS resource to receive and measure the CSI-RS resource, as one channel measurement value (for example, marked as N1) of the TRP corresponding to the CSI-RS1 group in the first CSI resource set. Specifically, for a corresponding CSI-RS resource in the CSI-RS group 1 in the second CSI resource set, during measurement, the terminal receives and measures the CSI-RS resource by using the QCL-type configured by the network side device on the resource or using the QCL-type parameter of the corresponding CSI-RS resource in the CSI-RS group 1 in the first CSI resource set, as an interference measurement value (for example, marked as N2) of the TRP corresponding to the CSI-RS group 1 in the first CSI resource set;

in this embodiment, for one CSI-RS resource in the CSI-RS group 2 in the first CSI resource set, during measurement, the terminal uses the QCL-type configured by the network side device on the CSI-RS resource to receive and measure the CSI-RS resource, as one channel measurement value (for example, marked as N3) of the TRP corresponding to the CSI-RS2 group in the second CSI resource set. Specifically, for the corresponding CSI-RS resource in the CSI-RS group 2 in the second CSI resource set, during measurement, the terminal receives and measures the CSI-RS resource by using the QCL-type configured by the network side device on the resource or by using the QCL-type parameter of the corresponding CSI-RS resource in the CSI-RS group 2 in the first CSI resource set, as an interference measurement value (for example, marked as N4) of the TRP corresponding to the CSI-RS group 2 in the first CSI resource set.

In the embodiment, when the terminal measures the L1-SINR values on the TRPs corresponding to the CSI-RS group 1 in the first CSI resource set and the second CSI resource set, the L1-SINR values are jointly determined by using the measured values N1 and N2. Specifically, when the terminal measures the L1-SINR values on the TRPs corresponding to the CSI-RS group 2 in the first CSI resource set and the second CSI resource set, the L1-SINR values are jointly determined by using the measured values N3 and N4.

Step n: and the terminal determines the CRI or the SSBRI contained in the N groups of measurement report values.

Step p: and the terminal determines the reporting formats corresponding to the N groups of measurement reporting values.

Step q: and the terminal reports the L1-RSRP measurement value corresponding to the CRI or the SSBRI in the N groups of measurement report values to the network side equipment through the PUCCH or PUSCH.

Example four:

in this embodiment, another implementation process of measurement reporting in which a network side device configures one reporting set for a terminal, and one reporting set corresponds to two CSI resource sets, and a reported measurement value is L1-SINR is described as an example.

In this embodiment, a network side device configures 1 CSI reporting set for a terminal, where the CSI reporting set corresponds to 2 CSI resource sets, and each CSI resource set includes K CSI-RS groups (explicit groups or implicit groups) (described below with K =2 as an example).

In the present embodiment, the CSI-RS set 1 in the first CSI resource set is used for channel measurement of one TRP (e.g. labeled as TRP 1), and the CSI-RS set 2 is used for interference measurement of TRP 1; the CSI-RS set 1 in the second set of CSI resources is used for channel measurement of another TRP (e.g. labeled TRP 2) and the CSI-RS set 2 is used for interference measurement of TRP 2. For measuring the inter-TRP interference, it may also be assumed that the CSI-RS group 2 of the first CSI resource set is the same as the CSI-RS group 1 of the second CSI resource set, and the CSI-RS group 2 of the second CSI resource set is the same as the CSI-RS group 1 of the first CSI resource set.

Specifically, the measurement reporting method in this embodiment is as follows:

step w: and the terminal determines a QCL-TypeD parameter on each CSI-RS resource according to the configuration of the network side equipment, receives the CSI-RS according to the determined QCL-TypeD parameter, and measures and determines the receiving power of each CSI-RS so as to determine the L1-SINR value.

In this embodiment, for one CSI-RS resource in the CSI-RS group 1 in the first CSI resource set, during measurement, the terminal uses the QCL-type configured by the network side device on the CSI-RS resource to receive and measure the CSI-RS resource, as one channel measurement value (for example, marked as P1) of the TRP corresponding to the CSI-RS1 group in the first CSI resource set. Specifically, for a corresponding CSI-RS resource in the CSI-RS group 2 in the first CSI resource set, during measurement, the terminal receives and measures the CSI-RS resource as an interference measurement value (for example, labeled as P2) of the TRP corresponding to the CSI-RS group 1 in the first CSI resource set, using the QCL-type configured by the network side device on the CSI-RS resource or using the QCL-type parameter of the corresponding CSI-RS resource in the CSI-RS group 1 in the first CSI resource set.

In this embodiment, for one CSI-RS resource in the CSI-RS group 1 in the second CSI resource set, during measurement, the terminal uses the QCL-type configured by the network side device on the CSI-RS resource to receive and measure the CSI-RS resource, as one channel measurement value (for example, labeled as P3) of the TRP corresponding to the CSI-RS group of the second CSI resource set. Specifically, for a corresponding CSI-RS resource in the CSI-RS group 2 in the second CSI resource set, during measurement, the terminal receives and measures the CSI-RS resource as an interference measurement value (for example, labeled as P4) of the TRP corresponding to the CSI-RS group 1 in the second CSI resource set, using the QCL-type configured by the network side device on the CSI-RS resource or using the QCL-type parameter of the corresponding CSI-RS resource in the CSI-RS group 1 in the second CSI resource set.

In the embodiment, when the terminal measures the L1-SINR values on the TRPs corresponding to the CSI-RS group 1 and the CSI-RS group 2 in the first CSI resource set, the L1-SINR values are jointly determined by using the measured values P1 and P2. And when the terminal measures the L1-SINR values on TRPs corresponding to the CSI-RS group 1 and the CSI-RS group 2 in the second CSI resource set, the L1-SINR values are jointly determined by using the measurement values P3 and P4.

Step x: and the terminal determines the CRI or the SSBRI contained in the N groups of measurement report values.

In this embodiment, the terminal determines the CRI or the SSBRI included in the reported N groups of measurement values according to the method in step b in the first embodiment, which is not described herein again.

And y: and the terminal determines the reporting formats corresponding to the N groups of measurement reporting values.

Step z: and the terminal reports the L1-RSRP measurement value corresponding to the CRI or the SSBRI in the N groups of measurement report values to the network side equipment through the PUCCH or PUSCH.

It should be noted that, in a specific implementation process, there may be 2 reporting sets, and each reporting set corresponds to one CSI resource set for measurement reporting; the number of the reporting sets can be 2, and each reporting set corresponds to two CSI resource sets for measurement reporting; of course, the number of reporting sets may also be 2, the 1 st reporting set in the 2 reporting sets corresponds to 1 CSI resource set, and the 2 nd reporting set in the 2 reporting sets corresponds to 2 CSI resource sets for measurement reporting.
