[0097] For ease of understanding, the following explains some aspects of the embodiments of this application:

[0098] 1. Channel State Information (CSI) Report

[0099] Typically, the CSI architecture can be divided into two parts: downlink CSI and uplink CSI. Downlink CSI architecture includes the downlink physical channel and downlink reference signal; uplink CSI architecture includes the uplink physical channel and uplink reference signal.

[0100] Typically, the downlink physical channel is used for data transmission, while the downlink reference signal is used for channel estimation to obtain downlink channel state information (CSI). Similarly, the uplink physical channel is used for uplink data transmission, while the uplink reference signal is used for channel estimation to obtain uplink channel state information (CSI).

[0101] In 5G systems, CSI is mainly used for adaptive beamforming and multiple input multiple output (MIMO) technologies to improve wireless transmission bandwidth and reliability.

[0102] Overall, the CSI architecture of 5G is a very important technology in 5G communication systems, playing a significant role in improving wireless transmission bandwidth, reliability, and interference coordination.

[0103] 1) CSI report content

[0104] Terminals typically determine CSI reports through higher-level signaling or default rules, which may include one of the following: 'none', 'cri-ri-pmi-cqi', 'cri-RI-i1', 'cri-RI-CQI', 'cri-RSRP', 'cri-SINR', 'tdcp', 'ssb-Index-RSRP', 'ssb-Index-SINR', or 'cri-RI-LI-PMI-CQI'.

[0105] If the terminal is configured with CSI-ReportConfig and the upper-level parameter reportQuantity is set to "none", then the terminal will not report anything for CSI-ReportConfig.

[0106] If the reportQuantity field in the higher-layer parameter CSI-ReportConfig is set to 'cri-RI-CQI', the terminal assumes that the precoding matrix indicator (PMI) is an identity matrix and only needs to report the CSI-RS Resource Indicator (CRI), Rank Indicator (RI), and Channel Quality Indicator (CQI), without needing to report the PMI.

[0107] For Type 2 CSI reports carried on the Physical Uplink Shared Channel (PUSCH), they are usually divided into two parts: CSI report part 1 and CSI report part 2. They are encoded independently, and the size of CSI report part 2 can be determined by CSI report part 1.

[0108] 2) CSI reporting

[0109] The current protocol supports sending a single CSI report to the network on a single uplink channel resource (Physical Uplink Control Channel (PUCCH) / Physical Uplink Shared Channel (PUSCH)), or sending multiple CSI reports to the network on a single uplink channel resource (PUCCH / PUSCH).

[0110] If the payload size of the CSI report is too large to be handled, the terminal may discard part of the CSI report or the entire CSI report, as agreed in the protocol.

[0111] In the case of a PUCCH associated with a CSI report, the PUCCH resource is selected from multiple PUCCH resources pre-configured by the network to carry the CSI report based on the uplink active bandwidth part (BWP) identifier (ID).

[0112] In the case of a PUSCH associated with a CSI report, the higher-layer signaling CSI report settings indicate multiple time slot offsets. The network uses DCI to indicate one of the time slot offsets for the terminal to determine the time domain location of the PUSCH, and further uses DCI to indicate the frequency domain location and other parameters of the PUSCH.

[0113] When multiple CSI reports are carried on a single PUCCH, the multiple CSI reports are typically mapped to a pre-configured PUCCH resource after a collision between the PUCCH resources carrying the CSI reports. When the pre-configured PUCCH resource cannot carry multiple CSI reports, the terminal may discard part of the content of some CSI reports or discard some CSI reports, according to the protocol.

[0114] When multiple CSI reports are carried on a single PUSCH, the network typically triggers multiple aperiodic CSI reports via Downlink Control Information (DCI). Each CSI report is configured with multiple slot offsets. The network indicates one of these slot offsets via DCI, and the terminal determines the PUSCH's location based on the maximum value of the associated slot offsets across the multiple CSI reports. Further, the frequency domain location and other parameters of the PUSCH are determined via DCI indication. When the pre-configured PUSCH resources are insufficient to carry multiple CSI reports, the terminal's behavior, according to the protocol, may involve discarding parts of some CSI reports or discarding all CSI reports altogether.

[0115] 2. Rate Splitting Multiple Access (RSMA)

[0116] The basic idea of ​​rate splitting is to split the messages sent to different receivers at the transmitter into two parts, called the dedicated part (dedicated data stream) and the common part (common data stream). Then, all the common parts are merged into a single unit and multiplexed using downlink non-orthogonal multiple access technology, namely Multiuser Superposition Transmission (MUST). This is achieved by designing a composite constellation and allocating constellation points and bits to different users. Next, similar to the multi-stream transmission of traditional Multi-User MIMO (MU-MIMO), the common data stream and multiple dedicated data streams are transmitted using different precoding and DMRS resources within the same time-frequency resources. At the receiver, each user, in addition to decoding its own dedicated data stream, also needs to decode the common data stream, and then merge its two parts into a complete data stream. It should be noted that the receiver may need to decode information sent to other users and perform interference removal when decoding the common data stream.

[0117] Data multiplexing is equivalent to the MUST technique when all data is transmitted using a public data stream. When all data uses a private data stream, data multiplexing is equivalent to the MU-MIMO method. Therefore, to a certain extent, RSMA is a combination of the MUST and MU-MIMO methods.

[0118] 3. Downlink Non-Orthogonal Multiple Access Technology

[0119] The main idea of ​​downlink non-orthogonal multiple access (NOMA) is to use superposition coding and successive interference cancellation (SIC) to carry information of multiple users on the same resource element (RE).

[0120] The following lists three overlay encoding methods: Cat 1, Cat 2, and Cat 3. Cat 1 and Cat 2 combine multiple sub-constellations into a composite constellation, while Cat 3 directly allocates different bits to different users based on a composite constellation.

[0121] Cat1: Different sub-constellations are superimposed with adaptive power ratios, and the mapping between points and bits in the composite constellation does not conform to the Gray mapping criterion. Figure 2aFor example, this is a composite constellation formed by superimposing two sub-constellations of size 4. The constellation point of the first sub-constellation is actually the center point of the clusters distributed across the four quadrants of the composite constellation. For instance, the four points located in the first quadrant, although with different specific values, all represent bit "00". The constellation point of the second sub-constellation is the constellation point of each cluster in the composite constellation. For instance, the last two bits of the first constellation point in each quadrant represent bit "10".

[0122] Cat2: Different sub-constellations are superimposed with adaptive power ratios, and the mapping between points and bits in the composite constellation conforms to the Gray mapping criterion. Figure 2b For example, this is a composite constellation formed by superimposing two sub-constellations of size 4 using the composite Gray mapping criterion. And Figure 2a Similar, only the bit mapping rules are slightly different.

[0123] For Cat1 and Cat2, the composite constellation they transmit is derived from the superposition of sub-constellations, and the variable controlling how the sub-constellations are superimposed is the power ratio. For the two-user case, the transmission steps at the transmitting end are as follows: The transmitting end first determines the constellation point to be transmitted based on the information bits of the first user, and then multiplies that constellation point by the power ratio. Where α is the power ratio of the second user; then, the transmitter determines the constellation point to be transmitted based on the information bits of the second user, and then multiplies that constellation point by the power ratio. Finally, the two constellation points are vector-summed to obtain the final composite constellation point for transmission. At the receiving end, the first user only needs to determine which quadrant the constellation point is located in to obtain the required bits, while the second user needs to determine not only which quadrant the constellation point is in, but also its specific position within the quadrant. In other words, the first user only needs to demodulate 2 bits; while the second user actually needs to demodulate 4 bits and then take the last 2 bits.

[0124] Cat3: Directly partitions a constellation point that conforms to the Gray mapping rule into bits. For example... Figure 2c The entire constellation diagram conforms to the Gray mapping rule, and it is agreed that the first 2 bits are the bits of the first user and the last 2 bits are the bits of the second user.

[0125] As can be seen, the sub-constellations of Cat1 and Cat2 can be different, and the composite constellation formed by superposition may be irregular. Cat3 first defines a regular composite constellation and then divides the bits.

[0126] For downlink NOMA, fully utilizing the channel conditions of different users is key to improving overall spectral efficiency. For example, for users with poor channel conditions, such as those far from the transmitter, the resolution of constellation points is poor. They can only distinguish constellation points with large Euclidean distances, such as those in different quadrants, but cannot accurately determine constellation points within the same quadrant. On the other hand, for users with good channel conditions, such as those close to the transmitter, the resolution of constellation points is good, and they can make accurate decisions even for constellation points with small Euclidean distances. In this case, it is equivalent to being able to decode all the bits transmitted by the transmitter and then extract the bits of interest. In practical applications, directly determining composite constellation points to obtain all bits and then extracting a portion of the bits is a computationally complex method. A less complex method is SIC: first determine the sub-constellation points with large Euclidean distances (i.e., the constellation points transmitted to distant users), then remove these sub-constellation points from the received signal (vector difference), and then determine the sub-constellation points with smaller Euclidean distances.

[0127] The following description, in conjunction with the accompanying drawings, details the measurement report sending method, measurement report receiving method, apparatus, and related equipment provided in this application through some embodiments and application scenarios.

[0128] See Figure 3 , Figure 3 This is a flowchart of a measurement report sending method provided in an embodiment of this application, such as... Figure 3 As shown, the method for sending measurement reports includes the following steps:

[0129] Step 101: The first terminal performs measurements based on the first type of Channel State Information Reference Signal (CSI-RS) resources and the second type of CSI-RS resources to obtain the first measurement quantity;

[0130] Step 102: The first terminal generates a second measurement based on the first measurement, wherein the second measurement is generated under the interference assumption that the second type of CSI-RS resource is used as the first type of CSI-RS resource;

[0131] Step 103: The first terminal generates a Channel State Information (CSI) measurement report based on the second measurement quantity and sends the CSI measurement report to the network-side device.

[0132] The CSI-RS resource may include any reference signal. For example, the CSI-RS resource may include a Synchronization Signal and PBCH block (SSB), a Demodulation Reference Signal (DMRS), a Phase-tracking Reference Signal (PT-RS), or a Sounding Reference Signal (SRS), etc.

[0133] Optionally, the first type of CSI-RS resource is associated with a first data stream, and the second type of CSI-RS resource is associated with a second data stream corresponding to at least one terminal. The receiving object of the first data stream is the at least one terminal, and the receiving object of the second data stream is the corresponding terminal. The at least one terminal includes the first terminal.

[0134] The first data stream can be a public stream of RSMA, and the second data stream can be a private stream of RSMA.

[0135] The first type of CSI-RS resource can be associated with the public flow of RSMA, while the second type of CSI-RS resource can be associated with the private flow of RSMA.

[0136] In this context, the recipient of the second data stream for each of the at least one terminals is the corresponding terminal.

[0137] The process of generating a second measurement based on the first measurement may include: the first terminal making a measurement assumption based on the first measurement to obtain the second measurement.

[0138] Measurement assumptions refer to how to construct the target channel's measurement quantity (second measurement quantity) based on the measurement results (i.e., the first measurement quantity) on associated CSI-RS resources. The target channel refers to the channel that the first terminal assumes exists and needs to measure and report the second measurement quantity. For example, it may need to report the signal-to-noise and interference ratio (SINR), channel quality indicator (CQI), and RI of the assumed Physical downlink shared channel (PDSCH). In the target channel, there are two types of signals: the first type is the signal that all terminals need to demodulate; the second type is the signal that the first terminal needs to demodulate. To demodulate the second type of signal, the first terminal needs to perform interference removal on the first type of signal. For ease of understanding, the first type of signal can be considered as a common stream corresponding to RSMA, while the second type of signal can be considered as a private stream corresponding to RSMA, which is also the traditional MU-MIMO data stream.

[0139] In one implementation, the network-side device may instruct the first terminal, at least in one of the following ways, how to determine the associated CSI-RS resources (including first-type CSI-RS resources and second-type CSI-RS resources) used to calculate the measurement quantity of the target channel:

[0140] Network-side configuration of CSI-RS resources related to the target channel;

[0141] The network side configures the physical resources associated with the target channel, or implicitly informs the physical resources, such as agreeing on the latest CSI-RS resources x times before sending the CSI measurement report, etc.

[0142] The associated CSI-RS resources can be used for channel measurement and / or interference measurement. Channel measurement refers to assuming the associated CSI-RS resources as the signal of the target channel, and using its first measurement as the useful signal power for calculating the second measurement. Interference measurement refers to assuming the associated CSI-RS resources as the interference signal of the target channel, and using its first measurement as the interference signal power for the second measurement.

[0143] The CSI measurement report may include the second measurement.

[0144] It should be noted that RSMA is a novel multiple access technology primarily used for downlink transmission. It improves transmission efficiency by superimposing two types of data streams (a common stream and a private stream), achieving better transmission performance than simply using MUST and MU-MIMO. Specifically, the common stream is the data stream that all receiving devices need to demodulate and decode, while the private stream is the data stream transmitted for a specific receiving device. After decoding the common stream, the receiver performs interference removal and demodulates the private stream. By flexibly utilizing both data streams, the common stream can compensate for the performance loss of MU-MIMO when the transmitting CSI information is imperfect or the channel isolation of the receiving device is poor.

[0145] However, the flexibility of RSMA introduces greater complexity to network-side scheduling. For example, how to configure appropriate precoders and power allocation for public and private flows, and how to use the public flow to serve multiple users (e.g., the percentage of data each user receives in the public flow). Furthermore, the RSMA public flow contains multiple data streams destined for multiple receiving devices, and there is mutual interference between it and the private flow. These characteristics differ significantly from traditional data flows, making existing CSI measurement mechanisms incomplete.

[0146] It should be noted that the first type of CSI-RS resource and the second type of CSI-RS resource in this application embodiment can correspond to the two types of data streams of RSMA respectively, so that the measurement information reported by the first terminal is more in line with the actual transmission performance during scheduling, which facilitates the network-side equipment to perform transmission scheduling and can improve transmission performance.

[0147] This application proposes a reference signal configuration and measurement method suitable for RSMA. It designs corresponding CSI measurement report configuration and measurement methods for two types of RSMA data streams, defines relevant measurement assumptions for RSMA (especially the common RSMA stream), and establishes a method for reporting measurement reports. This application provides richer CSI measurement information to the network, reducing the complexity of RSMA scheduling. Furthermore, this measurement information better reflects the transmission performance during actual scheduling, improving transmission reliability.

[0148] In this embodiment, a first terminal performs measurements based on a first type of Channel State Information Reference Signal (CSI-RS) resource and a second type of CSI-RS resource to obtain a first measurement quantity. The first terminal generates a second measurement quantity based on the first measurement quantity, wherein the second measurement quantity is generated under the interference assumption that the second type of CSI-RS resource is used as the first type of CSI-RS resource. The first terminal generates a Channel State Information (CSI) measurement report based on the second measurement quantity and sends the CSI measurement report to the network-side device. In this way, the first terminal generates a second measurement quantity using the first measurement quantity from the two types of CSI-RS resources and reports the CSI measurement report generated from the second measurement quantity. The first terminal can provide the network-side device with relatively rich CSI measurement information, facilitating transmission scheduling by the network-side device and improving transmission performance.

[0149] Optionally, the method further includes:

[0150] The first terminal receives the first configuration information sent by the network-side device;

[0151] The first terminal performs measurements based on a first type of CSI-RS resource and a second type of CSI-RS resource, including: the first terminal performs measurements using the first type of CSI-RS resource and the second type of CSI-RS resource based on the first configuration information; and / or,

[0152] The first terminal generates a second measurement based on the first measurement, including: the first terminal generates a second measurement based on the first configuration information and the first measurement.

[0153] The first configuration information is not limited to being carried by CSI-ReportConfig or csi-ReportSubConfig, but can also be carried by other information elements (IE), system messages, RadioResource Control (RRC) configuration, Medium Access Control (MAC) control element (CE), or DCI.

[0154] In one embodiment, the first configuration information can be used to configure the first terminal to measure the channel state information (CSI) of the target channel, the target channel being used to transmit a first data stream and a second data stream corresponding to at least one terminal.

[0155] In one embodiment, the first configuration information can be used to configure the first terminal to perform measurements based on a first type of CSI-RS resource and a second type of CSI-RS resource.

[0156] In one embodiment, the first configuration information can be used to configure the first terminal to generate a second measurement based on the first measurement.

[0157] In one embodiment, the first configuration information can be used to configure the first terminal to perform measurements based on a first type of CSI-RS resource and a second type of CSI-RS resource to obtain a first measurement quantity, and to configure the first terminal to generate a second measurement quantity based on the first measurement quantity.

[0158] In this embodiment, the first terminal performs measurements using first type CSI-RS resources and second type CSI-RS resources based on the first configuration information, and / or the first terminal generates a second measurement quantity based on the first configuration information and the first measurement quantity, so that the first terminal can generate the second measurement quantity according to the configuration of the network-side device.

[0159] Optionally, the first terminal performs measurements using first-type CSI-RS resources and second-type CSI-RS resources based on the first configuration information, including:

[0160] The first terminal selects parameters from the first configuration information and generates one or more measurement configurations based on the selected parameters;

[0161] The first terminal performs measurements using first-type CSI-RS resources and second-type CSI-RS resources based on the one or more measurement configurations to obtain a first measurement quantity.

[0162] The first configuration information may include a parameter group, which includes a set of parameters. The network-side device configures a set of parameters to the first terminal. This set of parameters includes combinable measurement resources and other parameters. The first terminal selects appropriate resources from the indicated available measurement resources for measurement and reporting.

[0163] The network-side device can configure multiple Type I CSI-RS resources and Type II CSI-RS resources for the first terminal to choose from, as well as measurement parameter restrictions. The first terminal can select measurement resources and other parameters to form one or more measurement configurations. Such a measurement configuration corresponds to a set of RSMA transmission configurations recommended by the first terminal to the network-side device.

[0164] In this embodiment, the first terminal selects parameters from the first configuration information and generates one or more measurement configurations based on the selected parameters. The first terminal then performs measurements using first-type CSI-RS resources and second-type CSI-RS resources based on the one or more measurement configurations to obtain a first measurement quantity. This allows the first terminal to independently select measurement resources to construct measurement configurations, improving measurement flexibility.

[0165] Optionally, the first configuration information includes one or more parameter groups;

[0166] The parameter set includes at least one of the following:

[0167] Index of the parameter group;

[0168] Index of Category 1 CSI-RS resources;

[0169] Index of Category 2 CSI-RS resources;

[0170] Parameter configuration of at least one of the first type of CSI-RS resources and the second type of CSI-RS resources;

[0171] Power indication information of at least one of the first type CSI-RS resources and the second type CSI-RS resources;

[0172] Measurement bias values ​​for Category I CSI-RS resources;

[0173] Stream count limitation information of at least one of the first type of CSI-RS resources and the second type of CSI-RS resources, or, stream count limitation information of the data channel associated with at least one of the first type of CSI-RS resources and the second type of CSI-RS resources;

[0174] Interference measurement assumptions for Type I CSI-RS resources, or, limiting information on interference measurement assumptions for Type I CSI-RS resources;

[0175] Interference measurement assumptions for Type II CSI-RS resources, or, limiting information on interference measurement assumptions for Type II CSI-RS resources;

[0176] The relationship between Category 1 and Category 2 CSI-RS resources;

[0177] Priority information for parameter groups;

[0178] The percentage information corresponding to each terminal in at least one terminal is used to generate the second measurement.

[0179] The index of the first type of CSI-RS resource can be used to associate a specific CSI-RS resource, or a specific port of a specific CSI-RS resource. The index of the first type of CSI-RS resource may include at least one of the following:

[0180] CSI-RS Resource Index;

[0181] CSI-RS resource group index;

[0182] Index of CSI-RS resources within their respective resource groups.

[0183] The CSI-RS resource can be one or more. If there are multiple resources, the index of the first type of CSI-RS resource can be a set of CSI-RS resource indexes.

[0184] It should be noted that, for ease of description, different ports of the same CSI-RS resource can be considered as different, independently distinguishable CSI-RS resources. In practical applications, port indexes are needed to distinguish different ports belonging to the same CSI-RS resource, and the embodiments of this application can be simply extended to this situation.

[0185] It should be noted that if a CSI-RS resource contains multiple ports, the network-side device can also indicate the port index in the CSI-RS resource.

[0186] If there is a nested configuration of resource groups, such as a CSI-RS resource belonging to a resource group that also belongs to a higher-level resource group, then the index of the resource group to which the CSI-RS resource belongs can include the index of the higher-level resource group. For example, if CSI-RS resource 1 belongs to CSI-RS resource subset 1, and Resource subset 1 belongs to Resource set 1, then when locating CSI-RS resource 1, it is also necessary to combine the indexes of set 1 and subset 1.

[0187] It should be noted that the term "resource group" refers to any structure that can contain at least one CSI-RS resource, such as a CSI-RS Resource Set and / or a CSI-RS Resource Group, etc., and there are no restrictions here.

[0188] The index of the second type of CSI-RS resource is similar to that of the first type of CSI-RS resource, and will not be repeated here.

[0189] In addition, the first or second “Category” CSI-RS resources can also be regarded as CSI-RS resources belonging to different groups. The fundamental difference is that these two types of CSI-RS resources will apply different measurement assumptions to calculate the measurement quantity and generate the measurement report. Therefore, if the CSI-RS resources are not grouped, the same effect as classification can be achieved by explicitly indicating the measurement assumptions of the CSI-RS resources or by implicitly indicating them according to parameters strongly bound to the category.

[0190] Among them, the parameter configuration of at least one of the first type of CSI-RS resources and the second type of CSI-RS resources (or expressed as the first type of CSI-RS resources and / or the second type of CSI-RS resources) can be used to indicate the specific parameters of the CSI-RS resources (the first type of CSI-RS resources and / or the second type of CSI-RS resources), such as resource location, period, quasi-co-location (QCL) reference, number of ports, orthogonal cover codes (OCC) sequence, sequence generation related parameters (such as scrambling method, initial value of random sequence, etc.), etc.

[0191] The power indication information of at least one of the first type of CSI-RS resources and the second type of CSI-RS resources may include at least one of the following:

[0192] The power bias value of at least one of the first type CSI-RS resources and the second type CSI-RS resources can refer to the power bias value between at least one of the first type CSI-RS resources and the given signal / channel. For example, the power bias value can be the power bias value of at least one of the first type CSI-RS resources and the second type CSI-RS resources relative to the transmission power of the given signal / channel.

[0193] The power ratio, power difference, or absolute power value between Category I CSI-RS resources and Category II CSI-RS resources, or between CSI-RS resources belonging to the same category;

[0194] The total power of Category I CSI-RS resources and Category II CSI-RS resources, or resources belonging to the same Category II CSI-RS resources;

[0195] The power bias value when the first type of CSI-RS resource is used as the hypothetical interference of the second type of CSI-RS resource.

[0196] It should be noted that the power indication information mentioned above may be the power assumptions for CSI-RS resources used when generating CSI reports.

[0197] In addition, the power bias value of the first type of CSI-RS resource as the hypothetical interference of the second type of CSI-RS resource can be used to compensate for imperfect interference removal of the common flow.

[0198] It should be noted that the power-related indication values ​​in the above power indication information can be linear values ​​or dB values.

[0199] The measurement bias value of the first type of CSI-RS resource may include at least one of the following:

[0200] Correction terms for measurements such as Reference Signal Received Power (RSRP) or SINR, for example, the result of addition, subtraction, multiplication, or division of RSRP or SINR measurement results and bias values;

[0201] Correction terms for rate (or channel capacity, throughput), such as the results of addition, subtraction, multiplication, or division of rate measurement results and bias values;

[0202] Corrections to CQI, such as the results of addition, subtraction, multiplication, or division of CQI measurement results and bias values;

[0203] CQI and rate correction term 1, for example, mapping the CQI measurement result to rate (or channel capacity, throughput), the calculation result based on rate and bias value, and finally mapping to the corrected CQI;

[0204] CQI and rate correction terms 2, for example, rate (or channel capacity, throughput) correction terms correct the rate measurement results and then map them to the corrected CQI.

[0205] It should be noted that the above measurement bias value can be used to indicate how much rate in the common flow is given to the measuring terminal.

[0206] The stream count limit for at least one of the first type of CSI-RS resources and the second type of CSI-RS resources may include the number of layers that each type of resource can be used as a multi-stream transmission assumption, such as the maximum number of layers; or, a combination of the number of multi-stream transmission layers of the first type of CSI-RS resources that are allowed or prohibited, and the number of multi-stream transmission layers of the second type of CSI-RS resources, such as only allowing {1 layer of the first type and 2 layers of the second type}.

[0207] Among them, the interference measurement assumptions for the first type of CSI-RS resources are as follows:

[0208] When measuring the {X1,X2,...}th type I CSI-RS resource, the {Y1,Y2,...}th type I CSI-RS resource is used as interference. In this case, it is assumed that the common flow also has multiple layers; or

[0209] When measuring the {X1,X2,...}th type I CSI-RS resource, the {Y1,Y2,...}th type II CSI-RS resource is used as interference.

[0210] Among them, the interference measurement assumptions for the second type of CSI-RS resources (which can be considered as the interference assumptions for private stream MU-MIMO) are as follows:

[0211] When measuring the {X1,X2,...}th type II CSI-RS resource, use the {Y1,Y2,...}th type II CSI-RS resource as interference; or

[0212] When measuring the {X1,X2,...}th type II CSI-RS resource, the {Y1,Y2,...}th type I CSI-RS resource is used as interference.

[0213] The association between the first and second types of CSI-RS resources can be understood or replaced as a pairing relationship between CSI-RS resources. This pairing relationship can be used to interfere with the above-mentioned interference hypothesis. The pairing relationship between CSI-RS resources can be indicated for the following reasons:

[0214] Explicit pairing, for example, indicating that the {X1,X2,...}th type I CSI-RS resource and the {Y1,Y2,...}th type II CSI-RS resource are paired resources; or

[0215] Implicit pairings include, for example, a pre-agreed or configured mapping relationship between the indexes of the first type of CSI-RS resource or resource group and the indexes of the second type of CSI-RS resource or resource group; or a pre-agreed or configured mapping relationship between two subsets of the same resource set.

[0216] In one embodiment, the first configuration information includes multiple parameter groups, each parameter group including a set of parameters. The network-side device configures multiple sets of parameters to the first terminal, and each set of parameters includes a set of measurement resources and other parameters.

[0217] Each set of parameters can correspond to one RSMA transmission configuration. Specifically, each set of parameters includes at least the following:

[0218] The index of this set of parameters;

[0219] Category 1 CSI-RS Resource Index;

[0220] Index of Category 2 CSI-RS resources;

[0221] Parameter configuration for Category I CSI-RS resources and / or Category II CSI-RS resources;

[0222] Power indication of Category I CSI-RS resources and / or Category II CSI-RS resources;

[0223] Measurement bias values ​​for Category I CSI-RS resources;

[0224] Stream count limits for Category I CSI-RS resources and / or Category II CSI-RS resources;

[0225] Interference measurement assumptions for Category I CSI-RS resources;

[0226] Interference measurement assumptions for Category II CSI-RS resources;

[0227] Pairing relationships between CSI-RS resources.

[0228] In one embodiment, the first configuration information includes a parameter group, which includes a set of parameters. The network-side device configures a set of parameters to the first terminal. This set of parameters includes composable measurement resources and other parameters. The first terminal selects appropriate resources from the indicated available measurement resources for measurement and reporting.

[0229] The network-side equipment can be configured with multiple Type I and Type II CSI-RS resources for the first terminal to choose from, as well as measurement parameter restrictions. The first terminal selects the measurement resources and other parameters to form one or more sets of measurement configurations. Such a set of measurement configurations corresponds to a set of RSMA transmission configurations recommended by the first terminal to the network side. The set of parameters includes at least:

[0230] An index of a first-class CSI-RS resource; or, a collection containing all CSI-RS resource indexes, indicating which can be used as an index of a first-class CSI-RS resource;

[0231] An index of a second-class CSI-RS resource, or a collection of all CSI-RS resource indexes, indicating which indexes can be used as second-class CSI-RS resources;

[0232] The parameter configuration of the first type of CSI-RS resource and / or the second type of CSI-RS resource, or, indicating the parameter configuration of all CSI-RS resources, and indicating which CSI-RS resource can be used as the first type or the second type;

[0233] Power indication of Category I CSI-RS resources and / or Category II CSI-RS resources;

[0234] Measurement bias values ​​for Category I CSI-RS resources;

[0235] The number of streams of data channels associated with (or assumed to be) Category I CSI-RS resources and / or Category II CSI-RS resources, for example: within each category of resources, there can be combinations of CSI-RS resources that can be used for multi-stream transmission.

[0236] Interference measurement assumptions for Type I CSI-RS resources may be restricted, for example: when measuring the {X1,X2,...}th Type I CSI-RS resource, only the {Y1,Y2,...}th Type I CSI-RS resource may or may not be allowed as interference; or, when measuring the {X1,X2,...}th Type I CSI-RS resource, only the {Y1,Y2,...}th Type II CSI-RS resource may or may not be allowed as interference.

[0237] Interference measurement assumptions for Category II CSI-RS resources, such as: when measuring the {X1,X2,...}th Category II CSI-RS resource, only the {Y1,Y2,...}th Category II CSI-RS resource may or may not be allowed as interference; or, when measuring the {X1,X2,...}th Category II CSI-RS resource, only the {Y1,Y2,...}th Category I CSI-RS resource may or may not be allowed as interference.

[0238] Similarly, when it is necessary to indicate pairing relationships, the explicit or implicit pairing methods described above can also be used to indicate pairing relationships between CSI-RS resources.

[0239] In this embodiment, through the aforementioned first configuration information, the first terminal can perform measurements using first type CSI-RS resources and second type CSI-RS resources based on the first configuration information; and / or, the first terminal can generate a second measurement quantity based on the first configuration information and the first measurement quantity.

[0240] Optionally, the power indication information is used to indicate at least one of the following:

[0241] Power bias value of at least one of the first type CSI-RS resources and the second type CSI-RS resources;

[0242] The power ratio, power difference, and / or absolute power value between Category I CSI-RS resources and Category II CSI-RS resources;

[0243] The power ratio, power difference, and / or absolute power value between at least one of the first-class CSI-RS resources and the second-class CSI-RS resources of the same type;

[0244] Total power of Category I CSI-RS resources;

[0245] Total power of Category II CSI-RS resources;

[0246] Total power of Category I CSI-RS resources and Category II CSI-RS resources;

[0247] The power bias value when the first type of CSI-RS resource is used as the hypothetical interference of the second type of CSI-RS resource.

[0248] Optionally, the first terminal generates a second measurement based on the first configuration information and the first measurement, including at least one of the following:

[0249] The first terminal corrects the first measurement based on the power indication information in the first configuration information, and obtains the second measurement based on the corrected first measurement.

[0250] The first terminal corrects the first measurement based on the measurement bias value in the first configuration information, and obtains the second measurement based on the corrected first measurement.

[0251] The first terminal generates a second measurement quantity using the first measurement quantity based on the stream count limit information in the first configuration information;

[0252] The first terminal generates a second measurement quantity using the first measurement quantity based on the association relationship between the first type of CSI-RS resources and the second type of CSI-RS resources in the first configuration information.

[0253] Wherein, the correction of the first measurement quantity by the first terminal based on the power indication information in the first configuration information may include at least one of the following:

[0254] (1) Power adjustment based on general (universal) power indication is mainly used to correct deviations in the first measurement caused by the transmitter using different transmission power when transmitting different CSI-RS resources. For example:

[0255] When the transmitter sends the first type of CSI-RS resource, the energy per resource element (EPRE) used is X dBm, while when sending the second type of CSI-RS resource, the EPRE used is Y dBm. At this time, by indicating the difference between X and Y (XY), such as Z, the first terminal can measure the received power (dBm) of the first type of CSI-RS resource as -Z, or the received power (dBm) of the second type of CSI-RS resource as +Z, so as to unify the assumed transmission power of the two CSI-RS resources to the same transmission power.

[0256] Alternatively, the transmitter can use the transmission power of other channels or signals (such as PDSCH, SSB, etc.) of a specified non-CSI-RS resource as a reference to unify the assumed transmission power of different CSI-RS resources. In this case, the difference between the EPRE of the CSI-RS resource and the EPRE of the reference channel or signal, such as Z, can be used. If the difference for the first type of CSI-RS resource is Z1 and the difference for the second type of CSI-RS resource is Z2, then the assumed transmission power of the two CSI-RS resources can be unified to the same transmission power by subtracting Z1 from the received power (dBm) of the first type of CSI-RS resource and subtracting Z2 from the received power (dBm) of the second type of CSI-RS resource. Z1 can be considered as the power bias value of the first type of CSI-RS resource, and Z2 can be considered as the power bias value of the second type of CSI-RS resource.

[0257] It is easy to understand that the above difference can also be reversed, such as the difference between Y and X. In that case, a sign needs to be added when adjusting, such as the received power (dBm) + Z for the first type of CSI-RS resource; and so on.

[0258] It's easy to understand that, in addition to EPRE, it can also be other power-related indicators, such as total transmit power, transmit power per symbol, transmit power per RB, etc.

[0259] It's easy to understand that, in addition to dBm and dB, other power-related units can also be used, such as W, mW, J / s, etc., and their specific values ​​can be linear or non-linear (such as dB).

[0260] (2) Power adjustment based on the power indication of a specific target channel is mainly used to correct the discrepancy between the assumed transmission power of the transmitter on the target channel and the transmission power of the CSI-RS resource (or the transmission power corrected by (1) above), which leads to a deviation in the first measurement, for example:

[0261] On the target channel, the total EPR (total power) of the first type of signal is X dBm, the total EPR of the second type of signal is Y dBm, and the EPR of the k-th sub-signal of the first type of signal is Xk dBm, and the EPR of the k-th sub-signal of the second type of signal is Yk dBm; while the EPR of the CSI-RS resources transmitted by the transmitting end is C dBm. At this point, by indicating the difference between Xk, Yk, and C, such as ZXk and ZYk, the first terminal can adjust the received power of each CSI-RS resource during measurement. For example, the received power (dBm) of the CSI-RS resource corresponding to the k-th sub-signal of the first type of signal can be set to ZXk, so that the assumed transmission power of the CSI-RS resource has the same transmission power as the corresponding signal on the target channel.

[0262] The first type of signal is the signal that all terminals need to demodulate; the second type of signal is the signal that the first terminal needs to demodulate. To demodulate the second type of signal, the first terminal needs to remove interference from the first type of signal. For ease of understanding, the first type of signal can be regarded as the common stream corresponding to RSMA, while the second type of signal can be regarded as the private stream corresponding to RSMA, which is also the traditional MU-MIMO data stream.

[0263] It is easy to understand that the above difference can also be reversed, such as the difference between C and ZXk. In that case, a sign needs to be added when adjusting, such as the received power (dBm) of the CSI-RS resource of the kth sub-signal of the first type of signal + ZXk; and so on.

[0264] It is easy to understand that the power difference mentioned above can also be indicated by other values, such as the absolute difference in power, the difference in nonlinear power (such as dBm), etc.

[0265] Alternatively, the received power of each CSI-RS resource can be adjusted by indicating the total EPRE power difference (including ratio, absolute difference, etc.) between different signal classes, and / or the power difference between different sub-signals within each signal class, as well as the total power of the target channel. For example, if the ratio of the total power of the first signal to the total power of the second signal is R, and the total transmit power of the target channel is P (mW), then the total power of the first signal is P*R / (R+1), in mW. Furthermore, given the power difference between different sub-signals within the first signal class, the transmit power of each sub-signal can also be calculated. The above powers are assumed transmit powers of each sub-signal of the target channel. Based on the difference between these assumed transmit powers and the actual transmit power of the CSI-RS resources, the received power of the corresponding CSI-RS resources can be adjusted.

[0266] It is easy to understand that, in addition to EPRE, it can also be other power-related indication values, such as total transmit power, transmit power per symbol, transmit power per RB, etc.

[0267] It's easy to understand that, in addition to dBm and dB, other power-related units can also be used, such as W, mW, J / s, etc., and their specific values ​​can be linear or non-linear (such as dB).

[0268] (3) Power adjustment based on power indications with specific interference assumptions, mainly to reflect the interference between different signals in the target channel, for example:

[0269] On the target channel, the receiver first detects the first type of signal, then performs interference removal on it, and then receives the second type of signal. Ideally, the first type of signal should not interfere with the second type of signal. However, due to imperfect factors, the first type of signal will still cause some interference to the second type of signal, such as a Z% energy leakage. Therefore, when measuring and calculating the interference of the second type of signal in the target channel, the received EPRE*Z% of the CSI-RS resource associated with the first type of signal can be used as the interference signal EPRE of the second type of signal.

[0270] Furthermore, the power of signals of the first type or the second type can also be adjusted using appropriate power adjustment methods.

[0271] It is easy to understand that the receiving power of the CSI-RS resources mentioned above can be the power modified by (1) and (2) above;

[0272] It's easy to understand that, in addition to EPRE, it can also be other power-related indicators, such as total transmit power, transmit power per symbol, transmit power per RB, etc.

[0273] It's easy to understand that, in addition to dBm and dB, other power-related units can also be used, such as W, mW, J / s, etc., and their specific values ​​can be linear or non-linear (such as dB).

[0274] The association between the first type of CSI-RS resources and the second type of CSI-RS resources in the first configuration information can refer to the relationship between associated CSI-RS resources under different assumptions. Multiple first-type signals and multiple second-type signals can exist on the target channel. Each signal can be a useful signal or an interference signal on the target channel, for example:

[0275] When it is assumed that the first sub-signal or sub-signal set in the first type of signal is a useful signal, the first type of signal or sub-signal set, or the second type of signal or sub-signal set, can be regarded as interference;

[0276] When the first sub-signal or sub-signal set in the second type of signal is assumed to be a useful signal, the first type of signal or sub-signal set, or the second type of signal or sub-signal set, can be regarded as interference.

[0277] The interference relationship between signals in the target channel determines how to use the first measurement of associated CSI-RS resources. For example, when signal X in the target channel acts as interference to signal Y, when calculating the SINR of signal X, its useful signal power is the RSRP of the CSI-RS resources associated with signal X, while the interference signal power is the RSRP of the CSI-RS resources associated with signal Y.

[0278] The interference relationship between signals in the target channel can be obtained through at least one of the following methods:

[0279] Based on the aforementioned pairing relationship of CSI-RS resources, and the relationship between the signals in the target channel and the associated CSI-RS resources;

[0280] Pre-configured;

[0281] First terminal selection, for example:

[0282] Given a signal and its associated CSI-RS resources, the first terminal selects at least one of the other available CSI-RS resources as an interference signal for that signal;

[0283] Optionally, the aforementioned interference measurement assumptions can be applied as constraints.

[0284] The stream count limit refers to the maximum stream count limit for each type of signal in the target channel, as well as the stream count limit when two types of signals are combined. The stream count limit refers to the number of signals that can be combined into mutually interfering signals in the target channel. For example, when the maximum is 2 layers, then for a given signal (or associated CSI-RS resource), at most one signal (or associated CSI-RS resource) can serve as its interfering signal. Through the stream count limit, the first terminal can understand the limitations of combining the first measurement quantity to obtain the second measurement quantity.

[0285] The first terminal can correct the first measurement based on the measurement bias value in the first configuration information. Taking rate-related correction as an example, it is mainly used to correct the data proportion of the first terminal in the first type of signal in the target channel, for example:

[0286] In the first type of signal, the amount of data occupied by the first terminal is X%. Therefore, when calculating the rate-related measurement, it needs to be multiplied by X%. For example, when the first measurement is Y kbps, the corrected value is Y*X%kbps.

[0287] Alternatively, if the first measurement is CQI, it can be converted into rate, and then the corrected rate can be obtained by following the operation in the previous step, and then converted back into CQI;

[0288] Alternatively, when the first measurement is CQI, the CQI can be corrected according to the pre-configured bias value to obtain the corrected CQI;

[0289] It is easy to understand that the above operations can also be extended to other rate-related measurements.

[0290] The second measurement may include a modified first measurement, or it may be modified again based on multiple modified first measurements, such as by performing addition, subtraction, multiplication or division operations on multiple modified first measurements to obtain the second measurement.

[0291] It should be noted that corrections can be made based on the calculation result of at least one first measurement, including corrections to the results of addition, subtraction, multiplication, or division of the corrected first measurement, such as the rate of the common flow multiplied by a percentage, and calculations of the calculation results of multiple first measurements, such as the rate of the common flow plus the rate of the private flow.

[0292] In this embodiment, the first terminal generates a second measurement quantity based on the first configuration information and the first measurement quantity. This enables the construction of a target channel measurement quantity (second measurement quantity) based on the measurement results (i.e., the first measurement quantity) on the associated CSI-RS resources. This makes the measurement information reported by the first terminal more consistent with the actual transmission performance during scheduling, which facilitates transmission scheduling by network-side equipment and can further improve transmission performance.

[0293] Optionally, the method further includes:

[0303] In one embodiment, the first configuration information includes multiple parameter groups, each parameter group including a set of parameters. The network-side device configures multiple sets of parameters to the first terminal. Based on the configured multiple sets of parameters, the network-side device can also indicate the reported measurement quantity to the first terminal, specifically including at least one of the following:

[0304] The number of parameter groups that can be reported;

[0305] And the parameter group index corresponding to the reported measurement;

[0306] Based on the measurements of the first type of CSI-RS resource in each set of parameters, such as CQI, RI, PMI and / or Layer Indicator (LI) corresponding to at least one first type of CSI-RS resource;

[0308] In each set of parameters, the measurement quantities based on the first and second types of CSI-RS resources, such as the RI, rate sum of the two types of CSI-RS resources, or the CQI corresponding to the rate sum, or the joint PMI based on the two types of CSI-RS, correspond to the second measurement quantity in Embodiment 2.

[0309] If the number of parameter groups configured for measurement is greater than the number of parameter groups that can be reported, the first terminal can be instructed on how to select parameter groups, such as selecting the optimal one based on the second measurement quantity.

[0310] In one embodiment, the first configuration information includes a parameter group, which comprises a set of parameters. The network-side device configures a set of parameters to the first terminal. This set of parameters includes composable measurement resources and other parameters. The network-side device can also indicate the reported measurement quantities to the first terminal, specifically including at least one of the following:

[0324] In one implementation, the first terminal can generate a second measurement based on a first measurement corresponding to the first type of CSI-RS resource and the proportion information corresponding to at least one terminal. For example, the first measurement corresponding to the first type of CSI-RS resource may include the rate of the common flow.

[0325] In this embodiment, the first terminal generates a second measurement based on the first measurement and the proportion information corresponding to at least one terminal. It can take into account the proportion information of the terminals to make measurement assumptions, so that the measurement information reported by the first terminal is more in line with the actual transmission performance during scheduling, which facilitates the network-side equipment to perform transmission scheduling and can further improve the transmission performance.

[0342] The first terminal can obtain K sets of CSI measurement reports, where K is the number of CSI measurement reports that the first terminal can report, corresponding to K sets of parameters.

[0343] In one implementation, the first configuration information includes multiple parameter groups, each parameter group including a set of parameters. The network-side device configures multiple sets of parameters to the first terminal. The first terminal reports according to the index of the K sets of parameters, including at least one of the following:

For example, the RI or rate sum of the first type of CSI-RS resource and the second type of CSI-RS resource, or the CQI corresponding to the rate sum, or the joint PMI based on the two types of CSI-RS, etc.

[0349] In one implementation, the first configuration information includes a parameter group, which comprises a set of parameters. The network-side device configures a set of parameters to the first terminal. This set of parameters includes composable measurement resources and other parameters.

[0356] It should be noted that the K sets of CSI measurement reports corresponding to the K sets of parameters can be carried independently by K uplink control information (UCI) or PUSCH (excluding other uplink channels), or at least partially or completely multiplexed into one UCI or PUSCH.

[0357] In this embodiment, the first terminal sends at least one CSI measurement report to the network-side device. Each CSI measurement report corresponds to a parameter group. The measurement information reported by the first terminal is more consistent with the actual transmission performance during scheduling, which facilitates the network-side device to perform transmission scheduling and can further improve transmission performance.

[0358] Optionally, the first terminal sends the CSI measurement report to the network-side device, including at least one of the following:

[0359] The first terminal sends a portion of the generated CSI measurement reports from the multiple CSI measurement reports to the network-side device according to the priority of the CSI measurement reports;

[0360] The first terminal sends a portion of the measurements in the generated CSI measurement report to the network-side device according to the priority of the measurements.

[0361] It should be noted that if multiple generated CSI measurement reports (such as K groups of CSI measurement reports) cannot be transmitted completely due to resource conflicts, uplink / downlink conflicts, or other reasons, some CSI measurement reports can be retained or discarded according to at least one of the following methods:

[0362] (1) Based on the implicitly defined priority, retain the high-priority measurement reports, such as:

[0363] Sort the measurements in the K groups of CSI measurement reports and retain some reports, for example, prioritize the reports with higher CQI scores; or

[0364] Priority is determined based on the index of the measurement report; for example, a smaller index indicates higher or lower priority.

[0365] (2) Based on the explicitly indicated priority, retain the high-priority measurement reports, such as:

[0366] When configuring measurement parameters, the network-side device simultaneously indicates the priority of each group of parameters. The first terminal then retains the measurement reports with higher priority based on the priority.

[0367] In addition, the first terminal may retain or discard some measurements in the CSI measurement report in at least one of the following ways:

[0368] (1) Based on the implicitly determined priority, retain the high-priority measurements, such as:

[0369] Measurement metrics can be divided into multiple parts. For example, PMI can be divided into wideband PMI and subband PMI, with wideband PMI having a higher priority than subband PMI by default; or

[0370] The priority of Category 1 CSI-RS resources is higher or lower than that of Category 2 CSI-RS resources by default.

[0371] (2) Based on the explicit priority indication, retain the high-priority measurement quantities, such as:

[0372] When configuring measurement parameters, the network-side device simultaneously indicates the priority of each measurement quantity in each group of parameters. The first terminal then retains the measurement quantity with higher priority based on the priority.

[0373] In this embodiment, the first terminal sends a portion of the generated CSI measurement reports from the multiple CSI measurement reports to the network-side device according to the priority of the CSI measurement reports; or, the first terminal sends a portion of the generated CSI measurement reports to the network-side device according to the priority of the measurement quantities, which can reduce reporting overhead.

[0374] Optionally, the generated CSI measurement report includes a first CSI measurement report and a second CSI measurement report;

[0375] The first terminal sends the CSI measurement report to the network-side device, including at least one of the following:

[0376] The first terminal sends the first CSI measurement report and the differential information of the second CSI measurement report relative to the first CSI measurement report to the network-side device;

[0377] The first terminal sends the first CSI measurement report to the network-side device, and the second CSI measurement report contains different measurement quantities compared to the first CSI measurement report.

[0378] In one implementation, the first CSI measurement report can be the i-th group of measurement reports. Based on the i-th group of measurement reports, the measurement reports subsequently reported by the first terminal are the difference values ​​relative to the i-th group of measurement reports. i can be 1, or it can be a configured or agreed value.

[0379] In one implementation, for CSI measurement reports with multiple identical values, the i-th group of measurement reports can be used as a reference, only the values ​​of the i-th group of measurement reports can be reported, and the measurement report index of the shared value can be indicated, while the shared value is not reported on these CSI measurement reports.

[0380] It should be understood that when multiple CSI measurement reports are carried by multiple UCIs or PUSCHs, the above method can also be used to reduce overhead, but it is necessary to indicate the associated UCI or PUSCH index, such as the UCI or PUSCH index where the baseline CSI measurement report is located.

[0381] In this embodiment, the first terminal sends the first CSI measurement report and differential information of the second CSI measurement report relative to the first CSI measurement report to the network-side device; or, the first terminal sends the first CSI measurement report to the network-side device, and the second CSI measurement report contains different measurement quantities relative to the first CSI measurement report. In this way, the first terminal can report multiple sets of CSI measurement reports using differential or shared parameters to reduce reporting overhead.

[0382] This application proposes a reference signal configuration and measurement method suitable for RSMA. It designs corresponding CSI measurement report configuration and measurement methods for the two types of data streams in RSMA, defines relevant measurement assumptions, and defines the reporting method for measurement reports. This application provides richer CSI measurement information to the network, reducing the complexity of RSMA scheduling. Furthermore, this measurement information better reflects the transmission performance during actual scheduling, improving transmission reliability.
