Abstract
Description
[0001] This application claims the priority of the Chinese patent application filed with the China Patent Office on April 2, 2021, with application number 202110363857.X and application name “A measurement reporting method and device”, the entire contents of which are incorporated by reference in this application. Technical Field
[0002] The present invention relates to the field of communication technology, and in particular to a measurement reporting method and device. Background Art
[0003] At present, when the network side equipment deploys multiple TRPs (T Ransmission Point, transmission points, and the terminal has multiple receiving antenna arrays (panels), the terminal can simultaneously receive signals from multiple TRPs, that is, it can simultaneously receive signals with multiple different QCL-TypeD (Quasi-Co-Location type D) parameters.
[0004] However, in the prior art, in both group-based beam reporting and non-group-based beam reporting, the terminal is not clear about which TRP the CSI-RS (Channel State Indication Reference Signal) in the CSI (Channel State Indication) measurement set comes from, so the reported 2 or up to 4 beams may be sent by the same TRP or different TRPs. For example, in a TRP transmission scenario, the beam reported by the terminal according to the maximum value of L1-RSRP (Layer-1 Reference Signal Receiveing Power) may be from the same TRP, that is, the measurement result is suitable for single TRP transmission, that is, it cannot provide valid measurement results for multi-TRP transmission.
[0005] It can be seen that the existing technology does not consider measurement reporting in multiple TRP and multi-panel scenarios, that is, a beam measurement reporting method in multiple TRP scenarios is urgently needed. Summary of the invention

[0144] Resources in different CSI-RS resource groups may be received simultaneously; or resources in the same CSI-RS resource group may be received simultaneously to determine a set of CSI-RS resource pairs that may be received simultaneously;
[0145] or,
[0146] Determine an association relationship between each QCL-TypeD parameter and a terminal receiving spatial domain filter; when receiving two CSI-RS resources, use different antenna arrays or antenna groups to simultaneously receive the two CSI-RS resources, and obtain an expected measurement result determined based on the QCL-TypeD parameters of the two CSI-RS resources and the association relationship, then determine that the two CSI-RS resources can be received simultaneously, so as to determine a set of CSI-RS resource pairs that can be received simultaneously;
[0147] or,
[0148] When the network side device configures the terminal to perform inter-group reporting or the terminal has not received the configuration of the network side device, it is determined to perform inter-group reporting, and the terminal selects specific CSI-RS resources that can be received simultaneously among the K CSI-RS resource groups; or, when the network side device configures the terminal to perform intra-group reporting, the terminal selects specific CSI-RS resources 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.
[0149] In a possible implementation manner, the processor further performs the following operations:
[0150] Determine a reporting format for the N groups of measurement reporting values, and report the N groups of measurement reporting values to the network side device using the reporting format.
[0151] In a possible implementation manner, the reporting format of the N groups of measurement reporting values is an intra-group difference format or an inter-group difference format.
[0152] In a possible implementation, the processor performs the following operations:
[0153] Determine that the second to wth measurement reported values included in each group of measurement reported values in the N groups of measurement reported values are all differences from the first measurement reported value in the group; wherein w is a positive integer not less than 2;
[0154] or,
[0155] Determine that a first group of measurement reported values among the N groups of measurement reported values is a measured L1-RSRP value or L1-SINR value; determine a difference between an r-th measurement reported value among the q-th group of measurement reported values excluding the first group of measurement reported values and an r-th measurement reported value among the first group of measurement reported values; and r is any value between 0 and w.

[0158] or,
[0159] Determine that the first measurement reported value in the first group of the N groups of measurement reported values is the measured L1-RSRP value or L1-SINR value, and the other measurement reported values except the first measurement reported value in the first group are the differences with the first measurement reported value in the first group of measurement reported values; wherein the r is any value from 0 to the w.
[0160] In a possible implementation, the processor performs the following operations:
[0161] The N groups of measurement reporting values are reported to the network side device in the reporting format through a physical uplink control channel PUCCH or a physical uplink shared channel PUSCH.
[0162] In a possible implementation, the processor performs the following operations:
[0163] When reporting the N groups of measurement reporting values, the preset T bits added in the uplink control information UCI indicate the position where a differential measurement value or a non-differential measurement value appears within a group, wherein T is determined based on the number of groups of measurement reporting values and the number of measurement reporting values in each group.
[0164] In a possible implementation, the processor performs the following operations:
[0165] When reporting the N groups of measurement reporting values, a preset number of bits added in the uplink control information UCI indicates the association between the measurement value and the CSI-RS resource group; or is used to indicate whether the corresponding CSI-RS resource groups are swapped in order.
[0166] In a possible implementation, the processor performs the following operations:
[0167] Determine the number of reporting bits for reporting each differential measurement value or each measurement value in the N groups of measurement values;
[0168] Based on the reporting bit number and a preset reporting rule, the N groups of measurement values are reported to the network side device.
[0169] According to a third aspect, a measurement reporting device is provided, the device comprising:
[0170] A first determining unit is used to determine, according to the configuration of the network side device, a quasi co-location type QCL-TypeD parameter of each channel state information reference signal CSI-RS group when used for measurement and a measurement set when used for measurement;
[0171] The second determining unit is used to measure the measurement set based on the QCL-Type D parameters to determine N groups of measurement reporting values; N is a positive integer not less than 1.
[0172] In a fourth aspect, the present invention implements a processor-readable storage medium, wherein the processor-readable storage medium stores a computer program, and the computer program is used to enable the processor to execute the method as described in any one of the first aspects.
[0173] In an embodiment of the present invention, the quasi-co-location type QCL-TypeD parameters and measurement set of each channel state indication reference signal CSI-RS group used for measurement can be determined according to the configuration of the network side device. For example, the network side device can configure a CSI resource set, and a CSI resource set includes K CSI-RS groups, each of the CSI-RS groups includes Z CSI-RS resources, and the CSI-RS resources in each CSI-RS group are configured with one or more QCL-TypeD parameters, so that the quasi-co-location type QCL-TypeD parameters of the CSI-RS group used for measurement and the measurement set to which the channel measurement and / or interference measurement belongs can be determined based on the configuration of the network side. Furthermore, the measurement set can be measured based on the QCL-TypeD parameters to determine N groups of measurement reporting values; N is a positive integer not less than 1. It can be seen that through the method provided in the embodiment of the present invention, the terminal can report N groups of measurement results when multiple TRPs are transmitted by the terminal, which helps the network side device to provide a suitable multi-TRP related transmission scheme for the terminal according to the measurement reporting value.

[0179] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the absence of conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other arbitrarily. In addition, although the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in an order different from that here.
[0180] In order to better understand this solution, some of the processes and nouns involved are explained below:
[0181] 1. Terminal equipment:
[0182] The terminal device involved in the embodiment of the present invention may be a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called a user equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs) and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, and a user device, but is not limited in the embodiments of the present invention.
[0183] 2. Network side equipment:
[0184] The network side device involved in the embodiment of the present invention may be a base station, which may include multiple cells providing services for the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network side device may be used to interchange received air frames with Internet Protocol (IP) packets, and serve as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network side device may also coordinate the attribute management of the air interface. For example, the network side device involved in the embodiment of the present invention may be a network side device (Base TransceiverStation, BTS) in the Global System for Mobile communications (Global System for Mobile communications, GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA), or a network side device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network side device (evolutional Node B, eNB or e-NodeB) in the long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (Home evolved Node B, HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., which is not limited in the embodiment 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 also be arranged geographically separately.
[0185] Specifically, the network side device and the terminal device can each use one or more antennas for multiple input multiple output (MIMO) transmission. MIMO transmission can be single user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or it can be diversity transmission, precoded transmission or beamforming transmission, etc.
[0186] 3. CSI reporting process:
[0187] In the existing protocol, the network side device can configure the CSI resource set (CSI Resource Setting, channel state information resource set) for the terminal, and its corresponding high-level parameters can be expressed as CSI-ResourceConfig; and the CSI reporting set (Reporting Setting), and its corresponding high-level parameters can be expressed as CSI-ReportConfig, for CSI measurement and reporting. Among them, each CSI reporting set is associated with up to 3 CSI resource sets, and a reporting quantity (report Quantity) is configured to indicate the content reported by the terminal. Specifically, the reported amount includes L1-RSRP (Layer-1 Reference Signal Received Power), which corresponds to the high-level parameter 'cri-RSRP' or 'ssb-Index-RSRP'; and, L1-SINR (Layer-1 Signal to Interference plus Noise Ratio), which corresponds to the high-level 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, CSI-RS resource indication), SSBRI (Synchronization Signal Block Resource Indicator, synchronization signal block resource indication), etc. or their combinations.
[0188] The terminal device can measure the CSI resource set associated with the CSI reporting set, and report according to the reporting amount configured in the CSI reporting set.
[0189] 4. Beam reporting:
[0190] L1-RSRP and L1-SINR are both reporting parameters for beam quality in the beam management process, and their reporting process adopts the CSI reporting process as described above.
[0191] Furthermore, the network side device can also configure the terminal to perform group based beam reporting and non-group based beam reporting. That is, the CSI reporting set configuration (CSI-ReportConfig) includes the parameter groupBasedBeamReporting. Specifically, the number of reported beams can be configured, that is, the parameter nrofReportedRS, and the number of reported beams is at most 4.
[0192] However, as mentioned above, the prior art does not consider measurement reporting in multiple TRP and multi-panel scenarios. For example, in the existing group-based beam reporting and non-group-based beam reporting, the terminal is not clear about which TRP the CSI-RS in the CSI measurement set comes from, so the reported 2 or up to 4 beams may be sent by the same TRP or different TRPs. For example, in a TRP transmission scenario, the beam reported by the terminal according to the maximum value of L1-RSRP may always come from the same TRP, which is a side result suitable for single TRP transmission, that is, it cannot provide valid measurement results for multi-TRP transmission.
[0193] In view of this, the present invention provides a measurement reporting method, through which a beam measurement reporting method in a multi-TRP scenario can be implemented, so that the terminal can report the measurement results required for simultaneous transmission of multiple TRPs.
[0194] See also Figure 1 , Figure 1 The figure is a flowchart of a measurement reporting method in an embodiment of the present invention.
[0195] Step 101: According to the configuration of the network side device, determine the quasi co-location type QCL-TypeD parameters of each channel state information reference signal CSI-RS group used for measurement and the measurement set used for measurement.
[0196] In an embodiment of the present invention, the network side device may configure one CSI resource set for the terminal, or may configure two CSI resource sets for the terminal, so that the terminal may determine the quasi-co-site type QCL-TypeD parameters of each channel state indication reference signal CSI-RS group when used for measurement and the measurement set when used for measurement based on the configuration of the network side device.
[0197] It should be noted that, in all embodiments of the present invention, a CSI resource set (i.e., CSI resource setting) can be configured with multiple CSI-RS resource sets (i.e., CSI resource set), and each CSI-RS resource set is a CSI-RS resource group. Alternatively, a CSI resource set can be configured with a CSI-RS resource set, and a CSI-RS resource set is configured with multiple CSI-RS resource subsets, and each CSI-RS resource subset is a CSI-RS resource group; or, a CSI resource set can be configured with a CSI-RS resource set, and a CSI-RS resource set contains multiple CSI-RS resources, and multiple CSI-RS resources are implicitly divided into multiple CSI-RS resource groups through high-level signaling parameters or group indexes or physical cell IDs.
[0198] Moreover, for the convenience of description, the following text will take the CSI-RS resource group as an example for explanation. In the actual implementation process, the measurement reporting method provided by this solution can be expressed based on the aforementioned CSI resource set or CSI resource set, and the present invention does not limit this. In addition, it should be noted that in the embodiment of the present invention, the CSI-RS group can be understood as a CSI-RS resource group.
[0199] The CSI-RS resources in all embodiments of the present invention may also be replaced by SSB resources, that is, the CSI resource setting or CSI resource set includes a case where the resource is an SSB (Synchronization Signal Block).
[0200] In the embodiment of the invention, the terminal determines the measurement set used for measurement in each CSI-RS group according to the configuration of the network side device, which can be implemented in but not limited to any of the following ways:
[0201] Method 1:
[0202] In an exemplary embodiment, if a network-side device configures a CSI resource set, and the CSI resource set includes K CSI-RS groups; when measuring the layer 1 signal to interference plus noise ratio L1-SINR of the m-th CSI-RS group, it is determined that the m-th CSI-RS group is used for channel measurement, and other CSI-RS groups except the m-th 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 used for channel measurement and for interference measurement belong to the measurement set.
[0203] For example, if K is 4, if the L1-SINR of the second CSI-RS group is measured, it can be determined that the second CSI-RS group is used for channel measurement, and the CSI-RS groups among the four CSI-RS groups except the second CSI-RS group, namely the first CSI-RS group, the third CSI-RS group and the fourth CSI-RS group are used for interference measurement.
[0204] Method 2:
[0205] In an exemplary embodiment, if a network-side device configures a CSI resource set, and the CSI resource set includes K CSI-RS groups; when measuring the layer 1 reference signal received power L1-RSRP of the m-th CSI-RS group, it is determined that the m-th CSI-RS group is used for channel measurement. Wherein, m is any value from 0 to K; K is a positive integer not less than 1; the CSI-RS group used for channel measurement belongs to the measurement set.
[0206] Method 3:
[0207] In an exemplary embodiment, if a network-side device configures a CSI resource set, and the CSI resource set includes K CSI-RS groups; when measuring the layer 1 reference signal received power L1-SINR of the m-th CSI-RS group, it is determined that the m-th CSI-RS group is used for channel measurement and interference measurement;
[0208] Wherein, m is any value from 0 to K; K is a positive integer not less than 1; and the CSI-RS groups used for channel measurement and for interference measurement belong to the measurement set.
[0209] Method 4:
[0210] In an exemplary embodiment, if the network side device is configured with two CSI resource sets, and each CSI resource set includes K CSI-RS groups; determine that the K CSI-RS groups corresponding to the first CSI resource set of the two CSI resource sets are used for channel measurement, and determine that any one of the K CSI-RS groups corresponding to the second CSI resource set of the two CSI resource sets is used for interference measurement as the CSI-RS group corresponding to any one CSI-RS group in the first CSI resource set. Wherein, m is any value from 0 to K; K is a positive integer not less than 1, and the CSI-RS groups used for channel measurement and interference measurement belong to the measurement set.
[0211] Method 5:
[0212] In an exemplary embodiment, if the network side device is configured with two CSI resource sets, and each CSI resource set includes K CSI-RS groups; the mth CSI-RS group of the first CSI resource set of the two CSI resource sets is determined to be used for channel measurement, and the mth CSI-RS group corresponding to the second CSI resource set of the two CSI resource sets is determined to be the mth CSI-RS group in the first CSI resource set for interference measurement. Wherein, m is any value from 0 to K; K is a positive integer not less than 1, and the CSI-RS groups used for channel measurement and interference measurement belong to the measurement set.
[0213] Method 6:
[0214] In an exemplary embodiment, if the network side device is configured with two CSI resource sets, and each CSI resource set includes K CSI-RS groups; the first CSI-RS group of each CSI resource set is determined to be used for channel measurement, and the CSI-RS groups other than the first 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, and the CSI-RS groups used for channel measurement and for interference measurement belong to the measurement set.
[0215] It can be seen that in the embodiment of the present invention, the measurement set may include only the CSI-RS group for channel measurement, may include the CSI-RS group for interference measurement, or may include the CSI-RS group for channel measurement and interference measurement at the same time.
[0216] In an embodiment of the invention, the terminal determines, according to the configuration of the network side device, the quasi co-location type QCL-TypeD parameter of each channel state indication reference signal CSI-RS group when used for measurement, which may be implemented in but not limited to any of the following ways:
[0217] Method 1:
[0218] In an embodiment of the present invention, if a network-side device configures a CSI resource set, and it can be determined that a CSI resource set includes K CSI-RS groups, and the CSI-RS resources in each CSI-RS group are configured with one or more QCL-TypeD parameters, where K is a positive integer not less than 1, and Z is a positive integer not less than 1, then it can be determined that the first QCL-TypeD parameter configured for each CSI-RS resource is the QCL-TypeD 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 other than the first QCL-TypeD parameter are the QCL-TypeD parameters when the CSI-RS resource is used for interference measurement. That is to say, when measuring the CSI-RS resource, the terminal can assume the QCL of the CSI-RS resource to be the sum of all configured QCL-typeD parameters or the union of all QCL-typeD parameters.
[0219] Method 2:
[0220] In an exemplary embodiment, if a network-side device configures a CSI resource set, and a CSI resource set includes K CSI-RS groups, and each CSI-RS group includes Z CSI-RS resources, and the CSI-RS resources in each CSI-RS group are configured with a QCL-TypeD parameter; the QCL-TypeD parameter configured for each CSI-RS resource can be determined as the QCL-TypeD 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 parameter configured for the CSI-RS resources corresponding to other CSI-RS groups among the K CSI-RS groups except the group where the CSI-RS resource is located is used as the QCL-TypeD parameter when the CSI-RS resource is used for interference measurement.
[0221] Method 3:
[0222] In an exemplary embodiment, if a network-side device configures a CSI resource set, and a CSI resource set includes K CSI-RS groups, and each CSI-RS group includes Z CSI-RS resources, and the CSI-RS resources in each CSI-RS group are configured with a QCL-TypeD parameter; then when measuring the m-th CSI-RS group, the QCL-TypeD parameter of the p-th CSI-RS resource of the m-th CSI-RS group is the union of the QCL-TypeD parameter configured for the p-th CSI-RS resource and the QCL-TypeD parameter configured for the CSI-RS resource corresponding to the CSI-RS group other than the m-th CSI-RS group; P is any value between 0 and Z, and Z is a positive integer not less than 1.
[0223] It should be noted that, in this embodiment, the QCL-TypeD parameter of the pth CSI-RS resource of the mth CSI-RS group may be a parameter used for channel measurement or a parameter used for interference measurement, which is not limited in this embodiment.
[0224] Method 4:
[0225] In an exemplary embodiment, if a network-side device configures a CSI resource set, and a CSI resource set includes K CSI-RS groups, and each CSI-RS group includes Z CSI-RS resources, and the CSI-RS resources in each CSI-RS group are configured with a QCL-TypeD parameter; the QCL-TypeD parameter configured for the CSI-RS resource is used as the QCL-TypeD parameter of each CSI-RS resource; wherein m is any value from 0 to K; and K is a positive integer not less than 1.
[0226] It should be noted that, in this embodiment, the QCL-TypeD parameter configured for the CSI-RS resource may be a QCL-TypeD parameter used for channel measurement or a QCL-TypeD parameter used for interference measurement, which is not limited in this embodiment.
[0227] Method 5:
[0228] In an exemplary embodiment, if the network side device is configured with 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 the second CSI resource set, the QCL-typeD parameter of the corresponding CSI-RS resource in the mth CSI-RS group of the first CSI resource set is used as the QCL-TypeD parameter of the CSI-RS resource in the mth CSI-RS group of the second CSI resource set. Wherein, m is any value from 0 to K; K is a positive integer not less than 1.
[0229] For example, assuming that K is 4, the CSI-RS groups corresponding to the first CSI resource set are CSI-RS group A1, CSI-RS group A2, CSI-RS group A3 and CSI-RS group A4, and the CSI-RS groups corresponding to the second CSI resource set are CSI-RS group B1, CSI-RS group B2, CSI-RS group B3 and CSI-RS group B4. It can be determined that when measuring the CSI-RS group B3, the QCL-typeD parameters of CSI-RS group A3 will be used as its QCL-typeD parameters.
[0230] Method 6:
[0231] In an exemplary embodiment, if the network side device is configured with 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, the QCL-typeD parameters of the corresponding CSI-RS resources in the 1st CSI-RS group of each CSI resource set are used 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; and K is a positive integer not less than 1.
[0232] It should be noted that, in this embodiment, the QCL-typeD parameter of the CSI-RS resource corresponding to the first CSI-RS group of each CSI resource set can be used as the QCL-typeD parameter for channel measurement of the CSI-RS resource corresponding to the first CSI-RS group of each CSI resource set, and can also be used as the QCL-typeD parameter for interference measurement of the CSI-RS resource corresponding to the first CSI-RS group of each CSI resource set, which is not limited in this embodiment.
[0233] In an embodiment of the present invention, when the CSI-RS group is a CSI-RS grouping explicitly configured by a network side device, the corresponding CSI-RS resources are two CSI-RS resources having the same sequence value or relative index value or the same index value in two CSI resource set configurations.
[0234] In an embodiment of the present invention, when the CSI-RS group is a CSI-RS resource implicit group, the corresponding CSI-RS resources are two CSI-RS resources with the same order value after the CSI-RS resources in the two CSI-RS resource implicit groups are sorted from low to high according to the index value; wherein the CSI-RS resource implicit group is a CSI-RS resource determined by implicitly grouping based on the high-level parameters or group index or physical cell ID contained in each CSI-RS resource.
[0235] In the embodiment of the present invention, the mth CSI-RS group in the aforementioned implementation manner may be determined in any of the following ways, but not limited to:
[0236] (1) The mth CSI-RS group is determined based on the configuration order or index of the CSI resource sets in the CSI resource set from small to large.
[0237] (2) The mth CSI-RS group is determined based on the order of the index values of the CSI-RS resources from small to large.
[0238] (3) The mth CSI-RS group is determined based on the values of the high-layer parameter configuration associated with the CSI-RS resource in ascending order.
[0239] (4) The mth CSI-RS group is determined based on the order of the indices of the CSI-RS resource with the smallest index in each CSI-RS group from small to large.
[0240] It can be seen that in the embodiment of the present invention, multiple methods can be used to determine the mth CSI-RS group, and multiple implementation plans are provided, which enhances the feasibility of the solution provided by the present invention.
[0241] Step 102: Measure the measurement set based on the QCL-Type D parameters to determine N groups of measurement reporting values; N is a positive integer not less than 1.
[0242] In an embodiment of the present invention, CSI-RS resources can be received according to the determined QCL-TypeD parameters, and the layer 1 reference signal received power L1-RSRP or the layer 1 signal to interference plus noise ratio L1-SINR measurement value can be determined. Then, according to the L1-RSRP or L1-SINR, the CSI-RS resource indication CRI or the synchronization signal block resource indication SSBRI included in the N groups of measurement reporting values can be determined.
[0243] In the embodiment of the present invention, the L1-RSRP or L1-SINR measurement values of the K CSI-RS groups corresponding to the CSI-RS resources are sorted from high to low to determine the CRI or SSBRI included in the measurement report value of any group in the N groups.
[0244] For example, the first group of CRI / SSBRI reported corresponds to the CSI-RS resource with the maximum L1-RSRP or L1-SINR value in each CSI-RS group; the second group of CRI / SSBRI reported corresponds to the CSI-RS resource with the second largest L1-RSRP or L1-SINR value in each CSI-RS group, and so on, thereby determining the N groups of measurement values reported.
[0245] In the specific implementation process, the zth group of CRI / SSBRI reported by the terminal is the CSI-RS resource with the zth largest L1-RSRP value in each CSI-RS group. Among them, the value of z is any value from 0 to N. The terminal selects the beam with the largest L1-RSRP value, that is, (CSI-RS resource) from the K CSI-RS resource implicit groups or CSI resource sets as the first group of measurement reporting values). Then, the beam with the second largest L1-RSRP value, that is, CSI-RS resource, is selected from the K CSI-RS resource implicit groups or CSI resource sets as the second group of measurement results; and so on, until the beam (CSI-RS resource) with the Nth largest L1-RSRP value is selected from the K CSI-RS resource implicit groups or CSI resource sets as the Nth group of measurement results. The mth (k = 1, 2, ..., K)th measurement value of each group of measurement results comes from the mth (k = 1, 2, ..., K)th CSI-RS resource implicit group or CSI resource set. If a CSI-RS resource is associated with multiple CSI-RS resource implicit groups or CSI resource sets, for example, with the k1th and k2th CSI-RS resource implicit groups or CSI resource sets, the measurement result corresponding to the CSI-RS resource may appear at the k1th and k2th positions of each group of measurement results when reported. The reporting method in this method may also be called inter-group reporting.
[0246] In an embodiment of the present invention, the L1-RSRP or L1-SINR reporting values included in a single CSI-RS group corresponding to a CSI-RS resource may also be sorted, and based on the maximum L1-RSRP or L1-SINR value within each CSI-RS group, the CRI or SSBRI included in the measurement reporting values of any group in the N groups may be determined.
[0247] For example, the first group of CRI / SSBRI reported is the CSI-RS resource with the largest L1-RSRP or L1-SINR value in a CSI-RS group; the second group of CRI / SSBRI reported is the CSI-RS resource with the second largest L1-RSRP or L1-SINR value in a CSI-RS group, and so on, thereby determining the reported N groups of measurement reporting values.
[0248] It can be seen that in the disclosed embodiment, the CSI-RS resources corresponding to all the maximum L1-RSRP or L1-SINR values in the K groups can be used as a group of measurement reporting values, that is, the measurement reporting values are determined by using the inter-group reporting method; the CSI-RS resources corresponding to the maximum L1-RSRP or L1-SINR value in any group of the K groups can also be used as a group of measurement reporting values, that is, the measurement reporting values are determined by using the intra-group reporting method. Obviously, the embodiment of the present invention provides a specific implementation method of the intra-group reporting method and the inter-group reporting method, which enhances the feasibility of the solution.
[0249] In a specific implementation process, the reported z-th group of CRI / SSBRI is the CSI-RS resources with the top M L1-RSRP values in the z-th CSI-RS group. n belongs to any value in 0-N. For example, when N = K, the first group of reported values corresponds to the 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 with relatively large L1-SINR values in the CSI-RS group; the second group of reported values corresponds to the CRI / SSBRI corresponding to M CSI-RS resources with relatively large L1-SINR values in the second CSI-RS group configured on the network device side; and so on, until it is determined that the N-th group of reported values corresponds to the CRI / SSBRI corresponding to M CSI-RS resources with relatively large L1-SINR values in the N-th CSI-RS group configured on the network device side. When N < K, the terminal can also select N groups of reports with relatively large L1-RSRP values. For example, select N groups according to the maximum L1-SINR within the group, or select N groups according to the top M L1-RSRP in each group. The reporting method in this method can also be called in-group reporting. At this time, it is required that N <= K and M <= P. Where P is a positive integer not less than 1.
[0250] In the embodiment of the present invention, N groups of measurement report values can also be determined according to the indication information of the network side device; specifically, if it is determined that the indication information is that the terminal determines to report measurement values within the CSI-RS group, the N groups of measurement report values include the CRI or SSBRI included in each group of measurement report values determined based on the descending order of the L1-RSRP or L1-SINR report values included in the K CSI-RS groups corresponding to the CSI-RS resources.
[0251] Specifically, if the indication information is that the terminal determines to report measurement values between CSI-RS groups, the N groups of measurement report values include the CRI or SSBRI included in each group of measurement report values determined based on the sorting of the L1-RSRP or L1-SINR report values included in a single CSI-RS group corresponding to the CSI-RS resources and based on the maximum L1-RSRP or L1-SINR value within each CSI-RS group.
[0252] Optionally, when the network side device does not configure or instruct the terminal to perform in-group reporting or between-group reporting, the terminal defaults to between-group measurement value reporting, that is, reporting according to the foregoing. Optionally, the terminal can indicate whether this report is in-group reporting or between-group reporting when reporting.
[0253] In the embodiment of the present invention, the terminal may also first determine a CSI-RS resource pair that meets the condition, thereby determining N groups of measurement reporting 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 that meets the condition may be determined in the following manner but is not limited to:
[0254] Method A:
[0255] In an embodiment of the present invention, the terminal can determine, based on predefined rules, that resources in different CSI-RS resource groups can be received simultaneously; or, resources in the same CSI-RS resource group can be received simultaneously to determine a set of CSI-RS resource pairs that can be received simultaneously.
[0256] Method B:
[0257] In an embodiment of the present invention, the terminal can determine the association relationship between each QCL-TypeD parameter and the terminal receiving spatial domain filter; wherein the association relationship is determined by the terminal based on previous measurement results, and when receiving two CSI-RS resources, different antenna arrays or antenna groups are used to simultaneously receive the two CSI-RS resources, and the expected measurement results determined by the QCL-TypeD parameters and the association relationship based on the two CSI-RS resources are obtained, then it can be determined that the two CSI-RS resources can be received simultaneously, thereby determining a set of CSI-RS resource pairs that can be received simultaneously.
[0258] Method C:
[0259] In an embodiment of the present invention, when the network side device configures the terminal to perform inter-group reporting or the terminal has not received the configuration of the network side device, it is determined to perform inter-group reporting, and the terminal selects specific CSI-RS resources that can be received simultaneously among the K CSI-RS resource groups; or, when the network side device configures the terminal to perform intra-group reporting, the terminal selects specific CSI-RS resources 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.
[0260] For example, assume that the beams (i.e., CSI-RS resources) included in the first CSI-RS resource implicit group or CSI resource set are [a1, a2, …, a4]; the beams (CSI-RS resources) included in the second CSI-RS resource implicit group or CSI resource set are [b1, b2, …, b4].
[0261] If the terminal determines to perform inter-group reporting, the inter-group beam pairs that can be received simultaneously are determined according to the terminal implementation or the configuration of the network-side device: [a1,b1], [a1,b2], [a2,b1], [a3,b3], [a3,b4], [a4,b2], [a4,b4]. Specifically, if it can be determined according to the predefined rules 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. At this time, the value of the beam pairs that the terminal can receive simultaneously is twice the value determined above.
[0262] If the terminal determines to report within the group, then the intra-group beam pairs that can be received simultaneously are [a1, a3], [a1, a4], [a2, a3], [a2, a4], [a3, a4], [a4, a1], [b1, b4] and [b2, b4] according to the terminal implementation or the configuration of the network side device. If it can be determined according to the predefined rules that any two intra-group beam pairs can be received simultaneously, or it is determined that any two intra-group beam pairs cannot be received simultaneously, that is, 0 pairs. In addition, [ai, aj] and [aj, ai] can also be considered as different beam pairs, and [bi, bj] and [bj, bi] can be considered as different beam pairs.
[0263] In an embodiment of the present invention, after determining a set of CSI-RS resource pairs that can be received simultaneously, the beam pairs included in the report, i.e., the CSI-RS resource pairs, can be determined based on the set of CSI-RS resource pairs that can be received simultaneously, so that the reported N groups or N pairs of beam pairs are not exactly the same.
[0264] In a possible implementation, the terminal may determine the CSI-RS resource of the sth layer 1 reference signal received power L1-RSRP in the set of CSI-RS resource pairs that can be received simultaneously as the first measurement reporting value in the sth group of measurement reporting values; and determine the CSI-RS resource of the sth L1-RSRP in the set of CSI-RS resource pairs that can be received simultaneously with the first CSI-RS resource as the second measurement reporting value in the sth group of measurement reporting values.
[0265] Specifically, the first measurement report value and the second measurement report value in each sth group in a set of CSI-RS resource pairs that can be received simultaneously can be used as N groups of measurement report values; wherein s is a sequential number determined based on the value of L1-RSRP.
[0266] In a specific implementation process, the sequence number can be determined for the value of L1-RSRP, wherein the value of L1-RSRP can be a CSI-RS resource of the L1-RSRP value on the CSI-RS resources in all CSI-RS resource implicit groups or CSI resource sets, or it can be limited to the L1-RSRP value on the CSI-RS resources in the first CSI-RS resource implicit group or CSI resource set, which is not limited in the embodiment of the present invention. Specifically, the sequence number with the largest L1-RSRP value can be determined as 1, the sequence number with the second largest L1-RSRP value can be determined as 2, and so on, to determine the sequence number corresponding to the L1-RSRP value.
[0267] It can be seen that when s is 1, the first group of measurement reporting values is the CSI-RS resource corresponding to the maximum L1-RSRP value. That is to say, the terminal determines that the first CSI-RS resource of the first group of measurement reporting values is the beam with the maximum L1-RSRP in the set of CSI-RS resource pairs that can be received simultaneously, and the second CSI-RS resource is the beam with the maximum L1-RSRP in the CSI-RS that can be received by the terminal simultaneously with the first CSI-RS resource. After determining the first group of measurement reporting values, the CSI-RS resource pair is deleted from the set of CSI-RS resource pairs that can be received simultaneously. Specifically, when determining the second group of measurement reporting values, the method used is the same as that for determining the first group of measurement reporting values, but the second group of reported measurement values determined by the set of CSI-RS resource pairs that can be received simultaneously is deleted after the first group of CSI-RS resource pairs are updated, and so on, so that the reported measurement values can be determined.
[0268] In a possible implementation manner, the sequence value determined from high to low by the sum of the L1-RSRP of two CSI-RSs in a CSI-RS resource pair in a set of CSI-RS resource pairs that can be received simultaneously may also be determined. Then, according to the sequence value, each group of measurement reporting values corresponding to the sequence value is determined, and based on the measurement reporting values corresponding to all CSI-RS resource pairs, N groups of measurement reporting values are determined; wherein T is a positive integer less than N. Specifically, the terminal selects a CSI-RS resource pair in a set S (S is a CSI-RS resource pair that meets the conditions) with the largest sum of the L1-RSRP of two CSI-RSs in a CSI-RS resource pair as the first group of measurement reporting values, selects a CSI-RS resource pair in a CSI-RS resource pair in S with the second largest sum of the L1-RSRP of two CSI-RSs as the second group of measurement reporting values, and so on, until N groups of measurement reporting pairs are selected.
[0269] 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], it can also be adjusted to [ai, bj] during actual reporting. That is, the first CSI-RS resource comes from a CSI resource set with a smaller CSI-RS resource implicit group index value or a higher layer parameter value, or a smaller CSI resource set index.
[0270] In other words, it can be ensured that the N CSI-RS resource pairs reported by the terminal, ie, the measurement reporting values, are not completely the same, so that more beam information can be provided in one report, thereby reducing feedback overhead.
[0271] In an embodiment of the present invention, after determining N groups of measurement reporting values, the difference corresponding to the N groups of measurement values can be determined based on the N groups of measurement reporting values, and the reporting format of the N groups of measurement reporting values can be determined based on the difference, and the N groups of measurement reporting values can be reported to the network side device using the reporting format.
[0272] In the embodiment of the present invention, after determining N groups of measurement reporting values, the differences corresponding to the N groups of measurement values may be determined, and the reporting format of the N groups of measurement reporting values may be determined to be an intra-group difference format or an inter-group difference format according to the differences.
[0273] In the embodiment of the present invention, the difference values corresponding to the N groups of measurement values may be determined by, but not limited to, the following method:
[0274] Method 1:
[0275] In an exemplary embodiment, it is determined that the second to wth measurement reported values included in each group of measurement reported values in N groups of measurement reported values are all differences from the first measurement reported value in the group, and w is a positive integer not less than 2.
[0276] Method 2:
[0277] In an exemplary embodiment, the first group of measurement reported values in N groups of measurement reported values is determined to be the measured L1-RSRP value or L1-SINR value; the difference between the rth measurement reported value of the measurement reported values in the qth group excluding the first group of measurement reported values and the rth measurement reported value in the first group of measurement reported values; r is any value from 0 to w.
[0278] Method 3:
[0279] In an exemplary embodiment, the first measurement reported value in the first group of N groups of measurement reported values is determined to be the measured L1-RSRP value or L1-SINR value, the measurement reported values in the first group except the first measurement reported value, and the measurement reported values other than the first group are determined to be the difference between the first measurement reported value and the first measurement reported value of the first group of measurement reported values; wherein r is any value from 0 to w.
[0280] Method 4:
[0281] In an exemplary embodiment, the first measurement reported value in the first group of N groups of measurement reported values is determined to be the measured L1-RSRP value or L1-SINR value, and the other measurement reported values except the first measurement reported value in the first group are determined to be the difference between the first measurement reported value in the first group of measurement reported values; wherein r is any value from 0 to w.
[0282] In the embodiment of the present invention, N groups of measurement reporting values may be reported to the network side device in an intra-group differential reporting format or an inter-group reporting format via PUCCH (physical uplink control channel) or PUSCH (physical uplink shared channel).
[0283] In the specific implementation process, it is assumed that the measurement reporting values reported by the terminal are 4 groups, and each group includes 2 measurement values, that is, the 8 L1-RSRP values reported by the terminal are RSRP#1, RSRP#2, RSRP#3, RSRP#4, RSRP#5, RSRP#6, RSRP#7, and RSRP#8; similarly, in the L1-SINR reporting, the 8 reported values are SINR#1, SINR#2, SINR#3, SINR#4, SINR#5, SINR#6, SINR#7, and SINR#8.
[0284] Specifically, in differential reporting, one or more (e.g., the largest one or more) measurement values are directly reported, that is, the one or more measurement values are directly reported, and the measurement value can be called a non-differential measurement value, and other measurement values other than the non-differential measurement value are differentially reported, and the measurement value can be called a differential measurement value. Specifically, the directly reported measurement value is quantized using a bits, and the differential measurement value is quantized using b bits. For example, a=7, b=4.
[0285] However, in one report, if the positions of the directly reported measurement values, ie, non-differential measurement values, and the differentially reported measurement values, ie, differential measurement values, are not fixed, the base station will not be able to correctly interpret the respective measurement values.
[0286] For example, assuming that RSRP#1 is quantized using 7 bits, other RSRPs are quantized using 4 bits, and CRI / SSBRI is 32 bits in total, the terminal reports 67 bits in one report. After receiving the UCI (uplink control information) reported by the terminal, the base station can determine that the first 32 bits represent CRI / SSBRI. For example, each CRI / SSBRI is 4 bits, for a total of 8 CRI / SSBRIs, the 33rd to 39th bits correspond to RSRP#1, the 40th to 43rd bits correspond to RSRP#2, and so on. If the measured value of RSRP#2 is the largest in a certain report and it is reported directly, while other measured values are reported differentially, the base station still receives 67 bits and interprets them according to the Rel-15 method, that is, it is considered that the first 32 bits represent CRI / SSBRI, the 33rd to 39th bits correspond to RSRP#1, the 40th to 43rd bits correspond to RSRP#2, and so on. This method leads to incorrect interpretation of RSRP#1 and RSRP#2.
[0287] Based on the aforementioned problems, in an embodiment of the present invention, when N groups of measurement reporting values are reported 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, N groups of measurement values are reported to a network side device, and a corresponding design is provided for the reporting method, so that the base station can correctly interpret the uplink control information, and thereby accurately obtain N groups of measurement reporting values.
[0288] In the embodiment of the present invention, differential reporting may be performed in the following manners, but not limited to:
[0289] Method 1:
[0290] In an embodiment of the present invention, when the reporting format is intra-group differential, when reporting N groups of measurement reporting values, the preset T bits added in the uplink control information UCI indicate the position where a non-differential measurement value appears within the group; the non-differential measurement value is used to represent the maximum measurement value within a group.
[0291] Optionally, if the reporting format is determined to be intra-group difference, that is, the measurement values other than the i-th measurement value in each group of N groups of measurement reporting values are all differentiated from the i-th measurement value in the group, where i is a positive integer greater than or equal to 1.
[0292] Specifically, the M measurement values in each group of the N groups of measurement reporting values correspond to K CSI-RS resource groups respectively. When M=K, the M measurement values in each group correspond to the K CSI-RS resource groups one by one.
[0293] In the embodiment of the present invention, when reporting N groups of measurement reporting values, a preset T bit may be added in the uplink control information UCI to indicate a position where a non-differential measurement value appears within a group.
[0294] Specifically, T of the preset T bits is determined based on the following formula:
[0295]
[0296] Wherein, N is used to represent the number of groups of measurement report values, and M is used to represent the number of measurement report values in each group. Operator used to represent a ceiling operation.
[0297] For example, when N=4 and M=2, T can be determined to be 4, that is, 4 bits are added to the uplink control information, and each bit indicates the position where the non-differential measurement value appears in a group. For example, 1 and 0 respectively indicate that the non-differential measurement value appears on the first or second measurement value in the group. For another example, when N=4 and M=4, T can be determined to be 8, that is, 8 bits are added to the uplink control information, and every 2 bits correspond to the position where the non-differential measurement value appears in a group, that is, one code point (00, 01, 10 or 11) corresponds to one position.
[0298] In an embodiment of the present invention, the position of the added T bit may be after or before CRI / SSBRI and / or L1-RSRP / L1-SINR, or may appear before or after each group of reported CRI, or may appear before or after each group of reported L1-RSRP / L1-SINR, and the embodiment of the present invention is not limited thereto.
[0299] For example, the added bit of T appears before CRI / SSBRI and / or L1-RSRP. When N=4 and M=2, the reporting format is shown in Table 1:
[0300]
[0301] Table 1
[0302] Among them, numbers #1 and #2 are the first group, #3 and #4 are the second group, #5 and #6 are the third group, #7 and #8 are the fourth group, and each bit indicates the position where the differential measurement value appears in a group. For example, if the differential measurement value appearance position indication is 0110, it can be determined that 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 are differential measurement values, that is, corresponding to RSRP#2, RSRP#3, RSRP#5, RSRP#8.
[0303] Method 2:
[0304] In an embodiment of the present invention, when reporting N groups of measurement reporting values, a preset T bit added in the uplink control information UCI indicates the position where a differential measurement value appears within a group, wherein T is determined based on the number of groups of measurement reporting values and the number of measurement reporting values in each group.
[0305] Optionally, when determining the jth measurement value of each group of N groups of measurement reporting values (except the i-th group) and the jth measurement value of the i-th group, where j=1, 2, ..., M; i=1, 2, ..., N.
[0306] In the embodiment of the present invention, T may be determined based on the following formula:.
[0307]
[0308] Wherein, N is used to represent the number of groups of measurement report values, and M is used to represent the number of measurement report values in each group. Operator used to represent a ceiling operation.
[0309] Similar to the method in method 1, add The bit indicates the position where the differential measurement value appears, and the added bit can appear after CRI / SSBRI and / or L1-RSRP / L1-SINR. For example, when N=2 and M=2, it can be determined that the first preset number is 2, that is, 2 bits are added, and the two bits respectively represent which group the first measurement value and the second measurement value are differentially calculated for. Further, when it is determined that 2 bits are added, and if one of the 2 bits is 0 and the other bit is 1, then the bit 0 indicates that the difference is calculated for the first group, and the bit 1 indicates that the difference is calculated for the second group; when the 2 bits are both 0, it means that the first measurement value of each group is differentially calculated for the first measurement value of the first group, and the second measurement value of each group is differentially calculated for the second measurement value of the first group.
[0310] For another example, when N=4 and M=2, it can be determined that the first preset number is 4, that is, 4 bits are added, and the bits also represent which group the first and second measurement values are differentially compared with, for example, every 2 bits represent the differential position of a measurement value. If the 4 bits are 0110, it can be determined that 01 represents that the first measurement value is differentially compared with the second group, and 10 represents that the second measurement value is differentially compared with the third group.
[0311] Method 3:
[0312] In the embodiment of the present invention, when the reporting format is inter-group difference, when reporting N groups of measurement reporting values, the T bits added in the uplink control information UCI indicate the position where the differential measurement value appears; the differential measurement value is used to characterize the measurement value in a group except the maximum measurement value.
[0313] Specifically, the inter-group difference is that the measured values other than the first measured value of the first group and the measured values other than the first group are all differentiated from the first measured value of the first group. And, the inter-group difference method can be further expanded to: the measured values other than the first measured value of the first group and the measured values other than the first group are all differentiated from the second measured value of the first group.
[0314] For example, if T is 1, then when the bit is 0, it indicates that the second measurement value of the first group is differentiated, and when the bit is 1, it indicates that the first measurement value of the first group is differentiated.
[0315] It should be noted that in the implementation of the above-mentioned methods 1, 2 and 3, each group of measurement reporting values and the CSI-RS resource group have a fixed association relationship, that is, when L1-RSRP is reported, multiple L1-RSRP values are always arranged in a fixed order. For example, when N=4 and M=2 mentioned above, RSRP#1, RSRP#2, RSRP#3, RSRP#4, RSRP#5, RSRP#6, RSRP#7, and RSRP#8 correspond to the 1st, 2nd, 1st, 2nd, 1st, 2nd, 1st, 2nd CSI-RS resource groups respectively. Similarly, CRI / SSBRI or L1-SINR values are always arranged in a fixed order.
[0316] Method 4:
[0317] In the present embodiment, when the reporting format is intra-group difference or inter-group difference, when reporting N groups of measurement reporting values, a preset number of bits added in the uplink control information UCI indicates the association between the measurement value and the CSI-RS resource group; or, is used to indicate whether the corresponding CSI-RS resource groups are swapped in order.
[0318] Exemplarily, the preset number of bits can be determined based on the method of determining T bits. For example, when N=4 and M=2, the second preset number can be determined to be 8. Specifically, the association between each measurement value or CRI / SSBRI and two CSI-RS resource groups (such as CSI resource sets) can be indicated in a bitmap manner, such as 0 represents the first CSI-RS resource group and 1 represents the second CSI-RS resource group. For example, for intra-group differentials, 01100110 indicates that the 8 reported measurement values correspond to the 1st, 2nd, 2nd, 1st, 1st, 2nd, 2nd, and 1st CSI-RS resource groups, respectively.
[0319] Still taking N=4, M=2 as an example, when intra-group differential is used, 1 bit can be used per group to indicate whether the measurement values of the group are changed in order, such as '1' indicates the order is changed, and '0' indicates that the order is not changed. For example, originally each group of 2 measurement values corresponds to the first and second CSI-RS resource groups, respectively. If the order is changed, it means that the current first measurement value is the second CSI-RS resource group, and the second measurement value corresponds to the first CSI-RS resource group. In this case, the L1-RSRP or L1-SINR in the group is always arranged in order from large to small.
[0320] Specifically, for inter-group differences, 1 bit can also be used to indicate whether the order of the two measurement values of the first group is swapped. The method is similar to the intra-group difference. Since the other groups are all differential measurement values for one measurement value of the first group, there is no need to swap the order. Therefore, this method does not need to indicate the order swap for other groups.
[0321] In the actual implementation process, please refer to Table 2, which shows the UCI overhead comparison of various reporting methods, where K represents the number of CSI-RS resources or SSB resources in each CSI-RS resource group, and a CSI-RS resource group can be a CSI resource set.
[0322]
[0323] Table 2
[0324] It can be seen from Table 2 that after supporting group-based beam reporting in a multi-TRP scenario, the UCI load increases significantly compared to the prior art. Therefore, an embodiment of the present invention also provides a solution for reducing the uplink control information load.
[0325] In the embodiment of the present invention, the number of reporting bits for each differential measurement value or each measurement value in the N groups of measurement values may be determined, and then the N groups of measurement values may be reported to the network side device based on the number of reporting bits and a preset reporting rule.
[0326] Optionally, it is possible to consider saving L1-RSRP or L1-SINR overhead to reduce the UCI load. Exemplarily, each differential measurement value uses a lower overhead when reporting, that is, the existing 4 bits can be reduced to 0, 1, 2 or 3 bits, that is, the number of reporting bits for each differential measurement value in the N groups of measurement values can be 0, 1, 2 or 3 bits. Specifically, the number of reporting bits for each differential measurement value in the N groups of measurement values can be reduced to a few bits, which can be pre-specified in the protocol, or configured by high-level signaling, or determined by the terminal itself, and is not limited in the embodiments of the present invention.
[0327] Exemplarily, the differential measurement value is reported using 0 bits, that is, only the direct measurement value is reported when reporting, and the differential measurement value is not reported, that is, the number of reporting bits for each differential measurement value in the N groups of measurement values is reduced to 0 bits. That is, when N=4 and M=2, when intra-group differential is used, one beam in each group (the beam reported in differential form) only reports CRI / SSBRI, and does not report the corresponding L1-RSRP or L1-SINR.
[0328] Exemplarily, the differential measurement value is reported using 1 bit. That is to say, only the direct measurement value is reported when reporting, and only 1 measurement value is reported as the differential measurement value, that is, the number of reporting bits for each differential measurement value in the N groups of measurement values is reduced to 1 bit. When intra-group differential is used, the 2nd to Mth beams (CRI / SSBRI) of each group, or the L1-RSRP or L1-SINR with the second largest to the Mth largest beam, the corresponding L1-RSRP or L1-SINR is reported with 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 it is 0; the reverse is also possible, for example, if the difference is within XdB, the second beam is 0, otherwise it is 1.
[0329] In this way, compared with the previous differential reporting method, the measurement value corresponding to each differential beam can reduce 3 bits of overhead. In addition, X can be a value predefined in the protocol, such as 8dB, or a value configured by RRC signaling, which is not limited in the embodiment of the present invention.
[0330] Exemplarily, the differential measurement value is reported using 2 or 3 bits, that is, the number of reporting bits for each differential measurement value in the N groups of measurement values is reduced to 2 or 3 bits. At this time, Y differential values or threshold values can be configured or predefined, and if the differential measurement value falls within a certain interval, the corresponding value is reported.
[0331] For example, the number of reporting bits for each differential measurement value in N groups of measurement values is 2, and the two differential values are defined as Y1 and Y2. Refer to Table 3, which shows the reporting values determined corresponding to the number of reporting bits for each differential measurement value in N groups of measurement values being 2.
[0332]
[0333] Table 3
[0334] For another example, the reporting bit number of each differential measurement value in the N groups of measurement values is still 2 bits, and the three differential values are defined as Y1, Y2 and Y3. Refer to Table 4, which shows the reporting value determined corresponding to the reporting bit number of 3 for each differential measurement value in the N groups of measurement values.

[0337] For example, the reporting bit number of each differential measurement value in the reported N groups of measurement values is 3 bits, and up to 7 difference values (or thresholds) can be defined, namely Y1, Y2, Y3, Y4, Y5, Y6, and Y7. Refer to Table 5, which shows the reporting values corresponding to the reporting bit number of 3 for each differential measurement value in the reported N groups of measurement values.

[0340] Optionally, it is also possible to consider reducing the overhead of CRI / SSBRI to reduce the load of UCI. For example, when the gap between the two beams is greater than ZdB, only the first CRI is reported, otherwise two CRIs are reported. Z can be a value pre-defined in the protocol, such as 8dB, or it can be a value configured by RRC signaling, which is not limited in the embodiments of the present invention. When the gap is too large, it means that the quality of the beam reported in differential form is poor and cannot provide services to the terminal, so the corresponding CRI / SSBRI may not be reported. Similarly, the corresponding L1-RSRP or L1-SINR may not be reported.
[0341] In order to facilitate understanding by those skilled in the art, several possible methods are listed below to illustrate the technical solution of measurement reporting. It should be understood that the following examples are only illustrative descriptions and do not constitute a limitation on the embodiments of the present invention. In addition to the methods listed below, other methods may be used in the specific implementation process, which are not exhaustive in this article.
[0342] Embodiment 1:
[0343] In this embodiment, if the network side device configures a CSI resource set for the terminal, and the CSI resource set includes multiple CSI resource sets, each CSI-RS resource set includes multiple CSI-RS resource groups, and each CSI resource set corresponds to 1 TRP. That is to say, the first embodiment takes a CSI reporting setting, i.e., a CSI reporting set and a CSI resource set as an example for explanation.
[0344] In one possible implementation, a CSI resource set may include multiple CSI-RS resources, and each CSI-RS resource includes high-level parameters related to its corresponding TRP during configuration. For example, the CSI-RS resource includes a high-level parameter CORESETPoolIndex, or a group index, or other high-level parameters, or a physical cell index (physical cellID).
[0345] It should be noted that there are at most K values for this high-level parameter, that is, the CSI-RS resources are implicitly divided into K groups, each group has P CSI-RS resources. For example, the value of K is 2, which means 2 TRPs. At this time, K implicit groups of CSI-RS resources can be included in one CSI resource set. Under this implicit grouping, it also supports configuring two or more TRP-related high-level parameters in one CSI-RS resource, such as configuring 2 group indexes, or including 2 or more values of a high-level parameter, such as the parameter CORESETPoolIndex takes values 0 and 1. That is, this way of expression can indicate that a CSI-RS resource is associated with 2 or more TRPs, for example, TRP1 and TRP2 both send reference signals on this CSI-RS resource. Optionally, 2 or more QCL-TypeD parameters can be configured for this CSI-RS resource.
[0346] In addition, it should be noted that in all embodiments of the present invention, it can be assumed that the number of CSI-RS resources in each group is equal. This assumption is only for the convenience of description. That is, the method in the present invention can also be extended to the situation where the number of CSI-RS resources in each group is not equal.
[0347] In an 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:
[0348] Step a: The terminal determines the QCL-TypeD parameters on each CSI-RS resource according to the network-side device configuration, receives the CSI-RS according to the determined QCL-TypeD parameters, and measures and determines the received power of each CSI-RS to determine the L1-RSRP value.
[0349] In an embodiment of the present 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 resources can be directly received according to the QCL-TypeD parameters pre-configured by the network side device for each CSI-RS resource in the CSI-RS group used for channel measurement, so that the receiving power of each CSI-RS can be measured and determined to determine the L1-RSRP value.
[0350] In the embodiment of the present invention, the CSI resource set also includes explicit grouping of other CSI-RS. For example, a CSI resource set explicitly configures two CSI resource sets, or a CSI resource set includes two CSI resource subsets (i.e., resource subsets), or a CSI resource set includes two CSI resource subsets (i.e., CSI resourcesubsets), etc., which are not limited in the embodiment of the present invention.
[0351] 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.
[0352] Step b: The terminal determines the CRI or SSBRI included in the N groups of measurement reporting values.
[0353] In the embodiment of the present invention, after the terminal determines the L1-RSRP value, it can determine the CRI or SSBRI included in the N groups of measurement reporting values based on the L1-RSRP value.
[0354] Specifically, the method for determining the measurement report value may refer to the inter-group reporting method and the intra-group reporting method described in step 102 to determine the measurement report value, which will not be described in detail here.
[0355] In a specific implementation process, if a CSI-RS resource is associated with multiple CSI-RS resource implicit groups or CSI resource sets, for example, associated with the first and second CSI-RS resource implicit groups or CSI resource sets, then the measurement results corresponding to the CSI-RS resource may appear at the first and second positions of each group of measurement results when reported.
[0356] Step c: The terminal determines the L1-RSRP measurement value corresponding to the CRI or SSBRI in the N groups of measurement reporting values.
[0357] In the embodiment of the present invention, after determining which beams (CRI or SSBRI) corresponding to L1-RSRP need to be reported through step a and step b, the measured values are quantized and reported. Some of the measured values are reported in a direct quantization manner, and other measured values are reported in a differential quantization manner from other unquantized measured values.
[0358] It can be determined from the reported N groups of measurement values that the second to wth measurement values in each group are all differences from the first measurement value in the group, where w is a positive integer not less than 2.
[0359] In a possible implementation, among the N groups of measured values reported, the first group of measured reported values in the N groups of measured reported values is determined to be the measured L1-RSRP value or L1-SINR value; the difference between the rth reported value of the qth group of measured reported values excluding the first group of measured reported values and the rth measured reported value of the first group of measured reported values. It can be seen that if the inter-group reporting method is adopted, it can be understood as performing a difference between multiple beams reported in each TRP.
[0360] In a possible implementation, among the N groups of measured values reported, the first measured reported value in the first group of the N groups of measured reported values is determined to be the measured L1-RSRP value or L1-SINR value, the reported values of the first group except the first measured value, and the reported values other than the first group are the difference between the first reported value and the first reported value of the first group of measured reported values; wherein r is any value from 0 to w.
[0361] In a possible implementation, the first measurement reported value in the first group of N groups of measurement reported values is determined to be the measured L1-RSRP value or L1-SINR value, and the other reported values except the first measurement reported value in the first group are determined to be the difference between the first measurement reported value and the first measurement reported value of the first group of measurement reported values; wherein r is any value from 0 to w.
[0362] Step d: The terminal reports the L1-RSRP measurement value corresponding to the CRI or SSBRI in the N groups of measurement reporting values to the network side device through PUCCH or PUSCH.
[0363] 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 and reporting, the L1-RSPR in all the above steps can be replaced by L1-SINR.
[0364] Embodiment 2:
[0365] 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, and this CSI reporting set corresponds to 1 CSI resource set. The CSI resource set includes K CSI resource sets, that is, CSI resource sets, that is, K CSI-RS groups, each CSI resource set includes P CSI-RS resources, and each CSI resource set corresponds to 1 TRP, that is, issued by the corresponding TRP or used by the terminal to measure the channel or interference of the corresponding TRP. Alternatively, the CSI resource set includes K*P CSI-RS resources, and each CSI-RS resource has a TRP-related high-level parameter during configuration, for example, the CSI-RS resource includes a high-level parameter CORESETPoolIndex, or a group index, or other high-level parameters, and the value of this high-level parameter is at most K, that is, the CSI-RS resources are implicitly divided into K groups, each group of P CSI-RS resources. A typical value of K is, for example, 2, indicating 2 TRPs. Under this implicit grouping, it is also supported to configure two or more TRP-related high-level parameters in one CSI-RS resource, such as configuring two group indexes, or including two or more values of a high-level parameter, such as the parameter CORESETPoolIndex with values of 0 and 1. In this case, it means that one CSI-RS resource is associated with two or more TRPs, for example, TRP1 and TRP2 both send reference signals on this CSI-RS resource. Optionally, two or more QCL-TypeD parameters can be configured for this CSI-RS resource.
[0366] In an embodiment, the L1-SINR reported by the terminal uses each implicit group of CSI-RS resources or CSI resource set for channel measurement and interference measurement. That is, an implicit group of CSI-RS resources or a CSI resource set is used for both channel measurement and interference measurement. At this time, the interference situation measured is a set of interferences experienced by the terminal, that is, all interferences. This embodiment provides a measurement method for measuring specific interference (such as interference between cells or between TRPs). It should be noted that in an embodiment of the present invention, an implicit group of CSI-RS resources or a CSI resource set is referred to as a CSI-RS group.
[0367] Please see attached Figure 2 , Figure 2 For example, CSI-RS group 1 and CSI-RS group 2 are associated with TRP1 and TRP2 respectively, that is, TRP1 sends a reference signal on the CSI-RS resources in CSI-RS group 1, and TRP2 sends a signal on the CSI-RS resources in CSI-RS group 2.
[0368] In a specific implementation process, when TRP1 sends a reference signal on the CSI-RS resource in CSI-RS group 1, it will interfere with the terminal receiving the signal on TRP2. Similarly, when TRP2 sends a reference signal on the CSI-RS resource in CSI-RS group 2, it will interfere with the terminal receiving the signal on TRP1. 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 perform channel measurement of TRP2 and interference measurement of TRP1 according to CSI-RS group 2.
[0369] In this embodiment, the specific measurement reporting method is:
[0370] Step f: The terminal determines the QCL-TypeD parameters on each CSI-RS resource according to the network side device configuration, receives the CSI-RS according to the determined QCL-TypeD parameters, and measures and determines the received power of each CSI-RS to determine the L1-SINR value.
[0371] Specifically, the L1-SINR value may be determined in the following two ways, but not limited to:
[0372] Method 1:
[0373] In this embodiment, taking K=2 as an example, the network side device configures two QCL-TypeD parameters for each CSI-RS resource in CSI-RS group 1 and CSI-RS group 2. It is assumed that the first QCL-TypeD parameter represents the QCL of the CSI-RS resource when used for channel measurement, and it is assumed that the second QCL-TypeD parameter represents the QCL of the CSI-RS resource when used for interference measurement.
[0374] In a specific implementation process, the terminal may use CSI-RS group 1 for channel measurement and CSI-RS group 2 for interference measurement, and the interference of TRP2 on TRP1 may be measured. Specifically, it is assumed that the number of CSI-RS resources in CSI-RS group 1 is equal to the number of CSI-RS resources in CSI-RS group 2.
[0375] It should be noted that in all embodiments of the present invention, CSI-RS resources include NZP (Non-zero Power CSI-RS resources and SSB (Synchronization Signal Block).
[0376] In a specific implementation process, for a CSI-RS resource in CSI-RS group 1, during measurement, the terminal can use the first QCL-TypeD configured by the network-side device on the CSI-RS resource to receive and measure the CSI-RS resource as a channel measurement value of the TRP corresponding to the first CSI-RS group (for example, marked as M1). At the same time, the second QCL-TypeD parameter configured by the network-side device can be used to receive and measure the CSI-RS resource as an interference measurement value of the TRP corresponding to the second CSI-RS group (for example, marked as M2).
[0377] In the specific implementation process, the same or similar method is used for a corresponding CSI-RS resource in CSI-RS group 2, that is, a CSI-RS resource corresponding to the measured CSI-RS resource in CSI-RS group 1. During measurement, the terminal uses the first QCL-TypeD configured by the network-side device on the CSI-RS resource to receive and measure the CSI-RS resource as a channel measurement value of the TRP corresponding to the second CSI-RS group (for example, marked as M3). At the same time, the second QCL-TypeD parameter configured by the network-side device is used to receive and measure the CSI-RS resource as an interference measurement value of the TRP corresponding to the first CSI-RS group (for example, marked as M4).
[0378] In this embodiment, when the terminal measures the L1-SINR value on the TRP corresponding to the first CSI-RS group, the measurement values M1 and M4 are used. In order to more accurately determine the interference situation based on M4, it can be assumed that the QCL-TypeD parameters when measuring the channel and measuring the interference are the same, that is, the second QCL-TypeD parameter of the CSI-RS in CSI-RS group 2 and the first QCL-TypeD parameter of the corresponding CSI-RS in CSI-RS group 1 are configured to the same value.
[0379] Specifically, in the same way, when the terminal measures the L1-SINR value on the TRP corresponding to the second CSI-RS group, the measurement values M3 and M2 are used. In order to more accurately determine the interference situation based on M2, it can be assumed that the QCL-TypeD parameters when measuring the channel and measuring the interference are the same, that is, the second QCL-TypeD parameter of a CSI-RS in CSI-RS group 1 and the first QCL-TypeD parameter of the corresponding CSI-RS in CSI-RS group 2 are configured to the same value.
[0380] It should be noted that, in all embodiments of the present invention, when performing L1-SINR measurement, if the CSI-RS group is a CSI resource set or an explicitly configured CSI-RS group, the corresponding CSI-RS resource refers to the two CSI-RS resources with the same sequence value in the two CSI resource set configurations. For example, the 4th CSI-RS resource configured in the first CSI-RS resource set and the 4th CSI-RS resource configured in the second CSI-RS resource set are corresponding. Specifically, if the CSI-RS group is a CSI-RS resource implicit group, the corresponding CSI-RS resource refers to the two CSI-RS resources with the same sequence value after the CSI-RS resources in the two implicit groups are sorted from low to high according to the index value. The two CSI-RS resource implicit groups refer to two CSI-RS resource implicit groups in the same CSI resource set, and can also be two CSI-RS resource implicit groups in different CSI resource sets.
[0381] Method 2:
[0382] Also taking K=2 as an example, the network side device configures one QCL-TypeD parameter for each CSI-RS resource in CSI-RS group 1 and CSI-RS group 2. When measuring each CSI-RS resource, the terminal uses the QCL-TypeD parameter configured by the network side device for channel measurement, and uses a predefined QCL-TypeD parameter for interference measurement.
[0383] In this embodiment, the terminal may use CSI-RS group 1 for channel measurement and CSI-RS group 2 for interference measurement, and then the interference of TRP2 on TRP1 may be measured. Specifically, it is assumed that the number of CSI-RS resources in CSI-RS group 1 is equal to the number of CSI-RS resources in CSI-RS group 2.
[0384] In this embodiment, for a CSI-RS resource in CSI-RS group 1, during measurement, the terminal uses the QCL-TypeD configured by the network-side device on the resource to receive and measure the CSI-RS resource as a channel measurement value (e.g., marked as M1) of the TRP corresponding to the first CSI-RS group. At the same time, the QCL-TypeD parameter configured for the CSI-RS resource corresponding to CSI-RS group 2 is used to receive and measure the CSI-RS resource as an interference measurement value (e.g., marked as M2) of the TRP corresponding to the second CSI-RS group.
[0385] Specifically, the same method is used for the corresponding CSI-RS resource in CSI-RS group 2, that is, the CSI-RS resource corresponding to the measured CSI-RS resource in CSI-RS group 1. During measurement, the terminal uses the QCL-TypeD configured by the network-side device on the resource to receive and measure the CSI-RS resource as a channel measurement value of the TRP corresponding to the second CSI-RS group (for example, marked as M3). At the same time, the QCL-TypeD parameter configured for the corresponding CSI-RS resource in CSI-RS group 1 is used to receive and measure the CSI-RS resource as an interference measurement value of the TRP corresponding to the first CSI-RS group (for example, marked as M4).
[0386] Specifically, when the terminal measures the L1-SINR value on the TRP corresponding to CSI-RS group 1, the measurement values M1 and M4 are used to jointly determine the L1-SINR value. And, when the terminal measures the L1-SINR value on the TRP corresponding to CSI-RS group 2, the measurement values M3 and M2 are used to jointly determine the L1-SINR value.
[0387] In this embodiment, the network side device may also configure or instruct the terminal on some assumptions or restrictions during measurement, such as using the same or different array panels to receive two implicit groups of CSI-RS resources or CSI resource sets or CSI-RS resources; or using the same or different spatial reception filters to receive two implicit groups of CSI-RS resources or CSI resource sets or CSI-RS resources; or instructing the terminal to perform superposition processing or interference processing on CSI-RS group 2 when measuring CSI-RS group 1. Similarly, the terminal may be instructed to perform superposition processing or interference processing on CSI-RS group 1 when measuring CSI-RS group 2.
[0388] In the case where the network side device is configured or not configured with the above assumptions or restrictions, the terminal may also report the above measurement assumptions or restrictions while reporting the measurement results.
[0389] Step g: The terminal determines the CRI or SSBRI included in the N groups of measurement reporting values.
[0390] 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 will not be described in detail here.
[0391] Step h: The terminal determines the L1-RSRP measurement value corresponding to the CRI or SSBRI in the N groups of measurement reporting values.
[0392] In this embodiment, the terminal determines the measurement value according to the method of determining the difference in step c in embodiment one. Specifically, the L1-RSRP in step c in embodiment one may be replaced with L1-SINR for processing, which will not be repeated here.
[0393] Step i: The terminal reports the L1-RSRP measurement value corresponding to the CRI or SSBRI in the N groups of measurement reporting values to the network side device through PUCCH or PUSCH.
[0394] Embodiment three:
[0395] In this embodiment, a network side device configures a reporting set for a terminal, and one reporting set corresponds to two CSI resource sets, and the reported measurement value is L1-SINR measurement reporting implementation process as an example for description.
[0396] In this embodiment, the network side device configures one CSI reporting set for the terminal. This CSI reporting set corresponds to two CSI resource sets. Each CSI resource set includes K CSI-RS groups (explicit groups or implicit groups) and is only used for reporting L1-SINR.
[0397] In this embodiment, the first CSI-RS group in the first CSI resource set (e.g., marked as CSI-RS group 1) is used for channel measurement of one TRP (e.g., marked as TRP1), and the second CSI-RS group (e.g., marked as CSI-RS group 2) is used for channel measurement of another TRP (e.g., marked as TRP2). Also, the first CSI-RS group in the second CSI resource set (e.g., marked as CSI-RS group 1) is used for interference measurement of TRP1, and the second CSI-RS group (e.g., marked as CSI-RS group 2) is used for interference measurement of TRP2. In order to measure inter-TRP interference, it can 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.
[0398] In this embodiment, the measurement reporting method is specifically as follows:
[0399] Step m: The terminal determines the QCL-TypeD parameters on each CSI-RS resource according to the network side device configuration, receives the CSI-RS according to the determined QCL-TypeD parameters, and measures and determines the received power of each CSI-RS to determine the L1-SINR value.
[0400] In this embodiment, for a CSI-RS resource in CSI-RS group 1 in the first CSI resource set, during measurement, the terminal uses the QCL-TypeD 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, marked as N1) of the TRP corresponding to the CSI-RS1 group in the first CSI resource set. Specifically, for the corresponding CSI-RS resource in CSI-RS group 1 in the second CSI resource set, during measurement, the terminal uses the QCL-TypeD configured by the network-side device on the resource or uses the QCL-TypeD parameter of the corresponding CSI-RS resource in CSI-RS group 1 in the first CSI resource set to receive and measure the CSI-RS resource 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;
[0401] In this embodiment, for a CSI-RS resource in CSI-RS group 2 in the first CSI resource set, during measurement, the terminal uses the QCL-TypeD 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, 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 CSI-RS group 2 in the second CSI resource set, during measurement, the terminal uses the QCL-TypeD configured by the network-side device on the resource or uses the QCL-TypeD parameter of the corresponding CSI-RS resource in CSI-RS group 2 in the first CSI resource set to receive and measure the CSI-RS resource 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.
[0402] In this embodiment, when the terminal measures the L1-SINR value on the TRP corresponding to the CSI-RS group 1 in the first CSI resource set and the second CSI resource set, the L1-SINR value is jointly determined using the measurement values N1 and N2. Specifically, when the terminal measures the L1-SINR value on the TRP corresponding to the CSI-RS group 2 in the first CSI resource set and the second CSI resource set, the L1-SINR value is jointly determined using the measurement values N3 and N4.
[0403] In this embodiment, the network side device may also configure or instruct the terminal on some assumptions or restrictions during measurement, such as using the same or different array panels to receive two implicit groups of CSI-RS resources or CSI resource sets or CSI-RS resources; or using the same or different spatial reception filters to receive two implicit groups of CSI-RS resources or CSI resource sets or CSI-RS resources; or instructing the terminal to perform superposition processing or interference processing on CSI-RS group 2 when measuring CSI-RS group 1. Similarly, the terminal may be instructed to perform superposition processing or interference processing on CSI-RS group 1 when measuring CSI-RS group 2.
[0404] In the case where the network side device is configured or not configured with the above assumptions or restrictions, the terminal may also report the above measurement assumptions or restrictions while reporting the measurement results.
[0405] Step n: The terminal determines the CRI or SSBRI included in the N groups of measurement reporting values.
[0406] 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 will not be described in detail here.
[0407] Step p: The terminal determines the reporting format corresponding to N groups of measurement reporting values.
[0408] In this embodiment, the terminal determines the measurement value according to the method of determining the difference in step c in embodiment one. Specifically, the L1-RSRP in step c in embodiment one may be replaced with L1-SINR for processing, which will not be repeated here.
[0409] Step q: The terminal reports the L1-RSRP measurement value corresponding to the CRI or SSBRI in the N groups of measurement reporting values to the network side device through PUCCH or PUSCH.
[0410] Embodiment 4:
[0411] In this embodiment, another implementation process of measurement reporting in which a network side device configures a reporting set for a terminal, one reporting set corresponds to two CSI resource sets, and the reported measurement value is L1-SINR is described as an example.
[0412] In this embodiment, the network side device configures one CSI reporting set for the terminal, and this CSI reporting set corresponds to two CSI resource sets, each of which includes K (K=2 is used as an example hereinafter) CSI-RS groups (explicit groups or implicit groups).
[0413] In this embodiment, CSI-RS group 1 in the first CSI resource set is used for channel measurement of one TRP (e.g., marked as TRP1), and CSI-RS group 2 is used for interference measurement of TRP1; CSI-RS group 1 in the second CSI resource set is used for channel measurement of another TRP (e.g., marked as TRP2), and CSI-RS group 2 is used for interference measurement of TRP2. In order to measure the interference between TRPs, it can also be assumed that CSI-RS group 2 of the first CSI resource set is the same as CSI-RS group 1 of the second CSI resource set, and CSI-RS group 2 of the second CSI resource set is the same as CSI-RS group 1 of the first CSI resource set.
[0414] Specifically, the measurement reporting method in this embodiment is:
[0415] Step w: The terminal determines the QCL-TypeD parameters on each CSI-RS resource according to the network side device configuration, receives the CSI-RS according to the determined QCL-TypeD parameters, and measures and determines the received power of each CSI-RS to determine the L1-SINR value.
[0416] In this embodiment, for a CSI-RS resource in CSI-RS group 1 in the first CSI resource set, during measurement, the terminal uses the QCL-TypeD 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, marked as P1) of the TRP corresponding to the first CSI resource set CSI-RS1 group. Specifically, for the corresponding CSI-RS resource in CSI-RS group 2 in the first CSI resource set, during measurement, the terminal uses the QCL-TypeD configured by the network side device on the CSI-RS resource or uses the QCL-TypeD parameter of the corresponding CSI-RS resource in CSI-RS group 1 in the first CSI resource set to receive and measure the CSI-RS resource as an interference measurement value (for example, marked as P2) of the TRP corresponding to the first CSI resource set CSI-RS group 1.
[0417] In this embodiment, for a CSI-RS resource in CSI-RS group 1 in the second CSI resource set, during measurement, the terminal uses the QCL-TypeD configured by the network side device on the CSI-RS resource to receive and measure the CSI-RS resource as a channel measurement value of the TRP corresponding to the second CSI resource set CSI-RS1 group (for example, marked as P3). Specifically, for the corresponding CSI-RS resource in CSI-RS group 2 in the second CSI resource set, during measurement, the terminal uses the QCL-TypeD configured by the network side device on the CSI-RS resource or uses the QCL-TypeD parameter of the corresponding CSI-RS resource in CSI-RS group 1 in the second CSI resource set to receive and measure the CSI-RS resource as an interference measurement value of the TRP corresponding to the second CSI resource set CSI-RS group 1 (for example, marked as P4).
[0418] In this embodiment, when the terminal measures the L1-SINR value on the TRP corresponding to CSI-RS group 1 and CSI-RS group 2 in the first CSI resource set, the L1-SINR value is jointly determined using the measurement values P1 and P2. When the terminal measures the L1-SINR value on the TRP corresponding to CSI-RS group 1 and CSI-RS group 2 in the second CSI resource set, the L1-SINR value is jointly determined using the measurement values P3 and P4.
[0419] Step x: The terminal determines the CRI or SSBRI included in the N groups of measurement reporting values.
[0420] 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 will not be described in detail here.
[0421] Step y: The terminal determines the reporting format corresponding to N groups of measurement reporting values.
[0422] In this embodiment, the terminal determines the measurement value according to the method of determining the difference in step c in embodiment one. Specifically, the L1-RSRP in step c in embodiment one may be replaced with L1-SINR for processing, which will not be repeated here.
[0423] Step z: The terminal reports the L1-RSRP measurement value corresponding to the CRI or SSBRI in the N groups of measurement reporting values to the network side device through PUCCH or PUSCH.
[0424] It should be noted that, in the specific implementation process, there may be 2 reporting sets, and each reporting set corresponds to one CSI resource set for measurement reporting; there may also be 2 reporting sets, and each reporting set corresponds to two CSI resource sets for measurement reporting; of course, there may also be 2 reporting sets, the first reporting set of the 2 reporting sets corresponds to 1 CSI resource set, and the second reporting set of the 2 reporting sets corresponds to 2 CSI resource sets for measurement reporting, which is not limited in the embodiments of the present invention.
