技术领域Technical Field

本公开涉及无线通信技术领域，尤其涉及一种信息上报方法、装置、终端及网络侧设备。The present disclosure relates to the field of wireless communication technologies, and in particular to an information reporting method, apparatus, terminal, and network-side equipment.

背景技术Background Art

在相干联合传输(coherent joint transmission，CJT)传输中，若多个传输点(Transmission Reception Points，TRP)的时间不同步或存在互易性误差会导致多个TRP相干传输的性能下降。可以通过终端，例如用户设备(User Equipment，UE)上报频域相位差，网络侧根据相位差对发送进行预处理来消除同步误差或互易性误差。In coherent joint transmission (CJT), time asynchrony or reciprocity errors between multiple transmission reception points (TRPs) can degrade coherent transmission performance. This can be mitigated by having terminals, such as user equipment (UE), report frequency-domain phase differences. The network then pre-processes the transmission based on these phase differences to eliminate synchronization or reciprocity errors.

然而，在时间同步误差较大，或者互易性误差频域粒度较小时，会导致频域相位差的上报开销过大，如对于1600ns的时间同步误差，在15kHz子载波间隔的情况下，相位差的上报粒度需要在资源块(resource block，RB)量级才能满足传输需求，使得频域基向量长度过长，显著增加终端处理复杂度。However, when the time synchronization error is large or the frequency domain granularity of the reciprocity error is small, the reporting overhead of the frequency domain phase difference will be too large. For example, for a time synchronization error of 1600ns, with a subcarrier spacing of 15kHz, the reporting granularity of the phase difference needs to be at the resource block (RB) level to meet the transmission requirements, which makes the frequency domain basis vector length too long, significantly increasing the terminal processing complexity.

为了便于更加清晰地理解本公开各实施例，首先对一些相关的知识进行介绍。In order to facilitate a clearer understanding of the various embodiments of the present disclosure, some relevant knowledge is first introduced.

一、Rel-16频域压缩上报方法：1. Rel-16 frequency domain compression reporting method:

Rel-16的频域压缩码本的一个层可以表示为一个P×N3的预编码矩阵：
One layer of the Rel-16 frequency domain compression codebook can be represented as a P×N 3 precoding matrix:

预编码表达式中的W1，和Wf分别对应空域压缩、线性合并系数和频域压缩。W 1 in the precoding expression, and Wf correspond to spatial domain compression, linear merging coefficient, and frequency domain compression, respectively.

二、空域压缩：2. Airspace Compression

空域压缩通过W1实现，
Spatial compression is achieved through W 1 ,

其中是维度N1N2×1的正交DFT向量，L是选定的空域基向量个数。W1为多层、多极化方向共用的空域基向量集合。总的空域基向量数量是N1O1N2O2，其中O1和O2为两个维度方向(垂直和水平方向)的过采因子。in are orthogonal DFT vectors of dimension N 1 N 2 × 1, and L is the number of selected spatial basis vectors. W 1 is the set of spatial basis vectors shared by multiple layers and multiple polarizations. The total number of spatial basis vectors is N 1 O 1 N 2 O 2 , where O 1 and O 2 are the oversampling factors in two dimensions (vertical and horizontal).

三、频域压缩：3. Frequency domain compression:

频域压缩通过Wf实现，对于多层传输，同一层内所有波束共用相同的频域基向量，不同层使用不同的频域基向量。对于层υ，频域基向量可以表示为：
Frequency domain compression is achieved through Wf . For multi-layer transmission, all beams in the same layer share the same frequency domain basis vector, and different layers use different frequency domain basis vectors. For layer υ, the frequency domain basis vector can be expressed as:

其中，表示Mυ个N3×1的正交DFT向量，Mυ为频域基向量的个数，为从{0,1,…,N3-1}中选择出的基向量索引集合。in, represents MυN 3 ×1 orthogonal DFT vectors, where Mυ is the number of frequency domain basis vectors. is a set of basis vector indices selected from {0, 1, ..., N 3 -1}.

当N3≤19时，采用单步指示方法。终端在选定频域基向量、计算好相应的合并系数后，可以使用相位旋转矩阵(也即循环移位操作)对频域基向量矩阵进行预处理(相乘)，保证最强系数(见后面的合并系数相关描述)对应的基向量为第一个频域基向量(索引为0)，这样在指示基向量时，仅需指示其它合并系数对应的频域基向量，减少反馈开销，即从N3-1个频域基向量中选出Mυ-1个，表示频域基向量的个数，R表示每个子带对应的预编码指示(Precoding Matrix Indicator，PMI)个数，由高层参数配置，pυ表示层υ的频域基向量个数缩放因子，数值在协议中预先定义(取值为1/4或1/8)。表示从A个基向量中选择B个基向量的排列组合数量，表示上取整操作。由于各个子带使用相同的相位旋转矩阵，则相位旋转矩阵不会影响系统性能，终端也无需对相位旋转矩阵进行上报。When N 3 ≤ 19, a single-step indication method is used. After selecting the frequency domain basis vectors and calculating the corresponding combining coefficients, the terminal can use the phase rotation matrix (i.e., cyclic shift operation) to preprocess (multiply) the frequency domain basis vector matrix to ensure that the basis vector corresponding to the strongest coefficient (see the following description of combining coefficients) is the first frequency domain basis vector (index is 0). In this way, when indicating the basis vector, only the frequency domain basis vectors corresponding to other combining coefficients need to be indicated, reducing feedback overhead, that is, M υ -1 are selected from N 3 -1 frequency domain basis vectors. Represents the number of frequency domain basis vectors, R represents the number of precoding matrix indicators (PMIs) corresponding to each subband, which is configured by high-level parameters, and pυ represents the scaling factor of the number of frequency domain basis vectors of layer υ, the value of which is predefined in the protocol (1/4 or 1/8). Represents the number of permutations and combinations of selecting B basis vectors from A basis vectors, Since each subband uses the same phase rotation matrix, the phase rotation matrix will not affect the system performance, and the terminal does not need to report the phase rotation matrix.

当N3>19时，采用两步指示方式，首先由终端确定一个中间基向量集合，包含2Mυ个频域基向量，通过参数Minitial指示中间基向量集合的起始位置，即从Minitial开始的连续2Mυ个频域基向量作为中间基向量集合。然后终端从中间基向量集合中选出Mυ-1个反馈给网络侧。When N 3 > 19, a two-step indication method is used. First, the terminal determines an intermediate basis vector set consisting of 2M υ frequency-domain basis vectors. The parameter M initial indicates the starting position of the intermediate basis vector set. That is, the continuous 2M υ frequency-domain basis vectors starting from M initial serve as the intermediate basis vector set. The terminal then selects M υ -1 from the intermediate basis vector set and feeds them back to the network.

四、线性合并系数：4. Linear merging coefficient:

合并系数通过实现。每一层只需要上报幅值较大的部分系数，其余系数可以假设为0，这样可以进一步降低反馈开销。网络侧为终端配置可以上报的最大的非零系数个数取值，当秩指示(rank indication，RI)＝1时，最大非零系数个数当RI>1时，所有层的最大非零系数个数为2K0。其中，β取值由协议预先定义。Merge coefficient by Each layer only needs to report the coefficients with larger amplitudes, and the remaining coefficients can be assumed to be 0, which can further reduce the feedback overhead. The network side configures the maximum number of non-zero coefficients that can be reported by the terminal. When the rank indication (RI) = 1, the maximum number of non-zero coefficients When RI>1, the maximum number of non-zero coefficients in all layers is 2K 0 , where the value of β is predefined by the protocol.

当误差较大时，若按照相关的频域压缩方法，且保证上报量的上报精度，需要以更小的频域粒度上报，如每个RB都需要反馈一个上报量，会导致基向量长度过长，进而导致终端确定频域基向量和合并系数时的计算复杂度过高，反馈开销也随之增加。When the error is large, if the relevant frequency domain compression method is followed and the reporting accuracy of the reported amount is guaranteed, it is necessary to report with a smaller frequency domain granularity. For example, each RB needs to feedback a reported amount, which will cause the basis vector length to be too long, and in turn cause the terminal to have too high computational complexity when determining the frequency domain basis vector and the combining coefficient, and the feedback overhead will also increase accordingly.

本公开实施例根据相位差的上报特性(例如子载波i+1和子载波i的相位差的理论值为其中τ为误差引的影响，在频域上原本就是稀疏的或分段稀疏的)提出一种基于分段的压缩上报方法，以降低反馈开销。其它与相位差具有类似特性(如在频域上是稀疏的)的测量量或上报量(如时间差，频率差，相位偏移等)也可以采用本发明中的分段压缩方法进行上报。The embodiment of the present disclosure is based on the reporting characteristics of the phase difference (for example, the theoretical value of the phase difference between subcarrier i+1 and subcarrier i is Where τ is the effect of error, which is inherently sparse or piecewise sparse in the frequency domain. A segmented-based compressed reporting method is proposed to reduce feedback overhead. Other measured or reported quantities (such as time difference, frequency difference, phase offset, etc.) with similar characteristics to phase difference (e.g., sparse in the frequency domain) can also be reported using the segmented compression method of this invention.

确定方式3、网络侧设备指示的每两段频域资源内的目标RB组之间的频域间隔；Determination method 3: the frequency domain interval between target RB groups within each two frequency domain resource segments indicated by the network side device;

需要说明的是，目标RB组之间的频域间隔与目标粒度不同，可以是目标粒度的整数倍。It should be noted that the frequency domain interval between target RB groups is different from the target granularity and can be an integer multiple of the target granularity.

确定方式4、协议预先规定的针对每段频域资源内的第n个RB组进行上报。Determination method 4: reporting is performed on the nth RB group in each frequency domain resource segment as pre-specified by the protocol.

本公开实施例中，根据第一频域资源的尺寸和目标粒度，确定第一频域资源对应的频域基向量和合并系数。此处目标粒度小于或等于协议中预先规定的信道状态信息(Channel State Information，CSI)的上报粒度。In the disclosed embodiment, a frequency domain basis vector and a combining coefficient corresponding to the first frequency domain resource are determined based on the size of the first frequency domain resource and a target granularity. Here, the target granularity is less than or equal to a reporting granularity for Channel State Information (CSI) specified in a protocol.

步骤102、向网络侧设备上报所述频域基向量及所述合并系数。Step 102: Report the frequency domain basis vectors and the combining coefficients to a network-side device.

在一些实施例中，终端根据第一频域资源的尺寸，确定第一频域资源对应的频域基向量和合并系数之后，向网络侧设备上报频域基向量及所述合并系数。网络侧设备接收到终端上报的第一频域资源对应的频域基向量和合并系数之后，根据第一频域资源对应的频域基向量和合并系数，对下行发送进行预处理，以消除时间同步误差或互易性误差。In some embodiments, after determining the frequency domain basis vectors and combining coefficients corresponding to the first frequency domain resource based on the size of the first frequency domain resource, the terminal reports the frequency domain basis vectors and the combining coefficients to a network-side device. After receiving the frequency domain basis vectors and combining coefficients corresponding to the first frequency domain resource reported by the terminal, the network-side device preprocesses the downlink transmission based on the frequency domain basis vectors and combining coefficients corresponding to the first frequency domain resource to eliminate time synchronization errors or reciprocity errors.

本公开实施例提供的信息上报方法中，通过使用频域资源分段的方法，第一频域资源为测量带宽内一段或多段频域资源，首先根据第一频域资源的尺寸，确定第一频域资源对应的频域基向量和合并系数，然后对第一频域资源(即分段频域资源)对应的频域基向量及合并系数进行上报，由于第一频域资源是测量带宽内一段或多段频域资源，而不是测量带宽整体，因而可以缩短频域基向量的长度，进而能够减小终端反馈开销，降低终端处理复杂度。In the information reporting method provided by the embodiment of the present disclosure, by using the frequency domain resource segmentation method, the first frequency domain resource is one or more frequency domain resources within the measurement bandwidth. First, according to the size of the first frequency domain resource, the frequency domain basis vector and the merging coefficient corresponding to the first frequency domain resource are determined, and then the frequency domain basis vector and the merging coefficient corresponding to the first frequency domain resource (i.e., the segmented frequency domain resource) are reported. Since the first frequency domain resource is one or more frequency domain resources within the measurement bandwidth, rather than the entire measurement bandwidth, the length of the frequency domain basis vector can be shortened, thereby reducing the terminal feedback overhead and the terminal processing complexity.

在一些实施例中，第一频域资源是通过对测量带宽内的频域资源进行分段后得到的，分段方法包括以下至少一项：In some embodiments, the first frequency domain resource is obtained by segmenting the frequency domain resources within the measurement bandwidth, and the segmentation method includes at least one of the following:

分段方法1、基于网络侧配置的分段方法：Segmentation method 1: Segmentation method based on network configuration:

网络侧将分段数量以及每段的起始RB或起始RB组指示给终端；The network side indicates the number of segments and the starting RB or starting RB group of each segment to the terminal;

或者网络侧将第一频域资源指示给终端，由终端确定其它分段的频域资源，例如将第一频域资源的起始RB索引和持续RB数指示给终端，或者将第一频域资源的起始RB组索引和持续RB组数指示给终端，或者将第一频域资源的起始第一子带编号和持续的第一子带数量指示给终端，或者将第一频域资源的起始第二子带编号和持续的第二子带数量指示给终端，或者以RB或RB组或第一子带或第二子带为粒度通过比特映射的方式指示终端。第一子带是对应目标粒度的子带，第二子带是对应CSI上报粒度的子带。Alternatively, the network side indicates the first frequency domain resource to the terminal, and the terminal determines the frequency domain resources of other segments, for example, indicating the starting RB index and the number of consecutive RBs of the first frequency domain resource to the terminal, or indicating the starting RB group index and the number of consecutive RB groups of the first frequency domain resource to the terminal, or indicating the starting first subband number and the number of consecutive first subbands of the first frequency domain resource to the terminal, or indicating the starting second subband number and the number of consecutive second subbands of the first frequency domain resource to the terminal, or indicating the terminal through bit mapping with RB or RB group or first subband or second subband as the granularity. The first subband is the subband corresponding to the target granularity, and the second subband is the subband corresponding to the CSI reporting granularity.

终端在确定第一频域资源后，确定其它分段的方法包括以下至少一种：After determining the first frequency domain resource, the terminal determines other segments in a method including at least one of the following:

1)根据第一频域资源的RB数或RB组数或第一子带数或第二子带数确定其它分段的持续RB数或RB组数或第一子带数或第二子带数；1) Determine the number of continuous RBs or RB groups or the number of first subbands or the number of second subbands in other segments according to the number of RBs or RB groups or the number of first subbands or the number of second subbands in the first frequency domain resource;

2)根据第一频域资源的RB数或RB组数或第一子带数或第二子带数确定分段数；2) Determine the number of segments according to the number of RBs or RB groups or the number of first subbands or the number of second subbands of the first frequency domain resource;

3)根据第一频域资源的RB数或RB组数或第一子带数或第二子带数确定其它分段的起始RB索引或起始RB组索引或起始第一子带索引或起始第二子带索引。3) Determine the starting RB index or starting RB group index or starting first subband index or starting second subband index of other segments according to the number of RBs or the number of RB groups or the number of first subbands or the number of second subbands of the first frequency domain resource.

分段方法2、基于预定义规则的分段方法：Segmentation method 2: Segmentation method based on predefined rules:

第一频域资源和其它频域资源均由终端根据预定义的规则确定，如协议中预先规定分段数量和/或每段包含的RB数或RB组数或第一子带数或第二子带数，分段方法和第一子带划分方法类似；终端根据预定义的每段包含的RB数或RB组数或第一子带数或第二子带数，或者分段数量，确定每段对应的频域资源。The first frequency domain resources and other frequency domain resources are determined by the terminal according to predefined rules. For example, the number of segments and/or the number of RBs or RB groups or the first subband number or the second subband number contained in each segment are pre-specified in the protocol. The segmentation method is similar to the first subband division method; the terminal determines the frequency domain resources corresponding to each segment based on the predefined number of RBs or RB groups or the first subband number or the second subband number contained in each segment, or the number of segments.

分段方法3、终端确定的分段方法：Segmentation method 3, segmentation method determined by the terminal:

终端根据第一粒度或目标粒度确定第一频域资源的RB数或RB组数或第一子带数或第二子带数，然后将第一频域资源的起始RB索引或起始RB组索引或起始第一子带索引或起始第二子带索引指示给网络侧。终端将分段数量或第一频域资源包含的RB数或RB组数或第一子带数或第二子带数指示给网络侧。The terminal determines the number of RBs, RB groups, first subbands, or second subbands of the first frequency domain resource based on the first granularity or the target granularity, and then indicates the starting RB index, starting RB group index, starting first subband index, or starting second subband index of the first frequency domain resource to the network side. The terminal indicates the number of segments, the number of RBs, RB groups, first subbands, or second subbands included in the first frequency domain resource to the network side.

本公开实施例中第一频域资源可以包括以下至少一项：In the embodiment of the present disclosure, the first frequency domain resource may include at least one of the following:

1)信道质量指示(Channel Quality Indicator，CQI)质量大于第一阈值的一个或多个子带。1) One or more subbands whose channel quality indicator (CQI) quality is greater than a first threshold.

例如，这里的子带是对应第一粒度或目标粒度的子带。For example, the sub-band here is a sub-band corresponding to the first granularity or the target granularity.

2)信干噪比(Signal to Interference Noise Ratio，SINR)质量大于第二阈值的一个或多个子带；2) one or more subbands whose signal-to-interference-noise ratio (SINR) quality is greater than a second threshold;

3)所述终端选定的一个或多个子带、或多个RB或多个RB组；3) one or more subbands, or multiple RBs, or multiple RB groups selected by the terminal;

4)带宽中间的一个或多个子带、或多个RB或多个RB组；4) One or more subbands, or multiple RBs, or multiple RB groups in the middle of the bandwidth;

6)网络侧配置的多个子带索引、或多个RB或多个RB组。6) Multiple subband indices, or multiple RBs, or multiple RB groups configured on the network side.

本公开实施例提供的信息上报方法中，终端根据测量带宽内的一个或多个频域资源和第一粒度或目标粒度确定第一上报量(如相位差)，第一上报量对应的频域基向量和合并系数并进行上报，其中目标粒度小于等于第一粒度，其中第一粒度为协议中预先规定的CSI上报粒度，用于第一上报量以外其他上报量的上报粒度。In the information reporting method provided by the embodiment of the present disclosure, the terminal determines a first reporting quantity (such as a phase difference) based on one or more frequency domain resources within the measurement bandwidth and a first granularity or a target granularity, and reports the frequency domain basis vector and the combining coefficient corresponding to the first reporting quantity, wherein the target granularity is less than or equal to the first granularity, wherein the first granularity is a CSI reporting granularity pre-specified in the protocol, and is used for reporting granularity of other reporting quantities other than the first reporting quantity.

具体地，本公开实施例提供的信息上报方法为一种分段的相位差压缩上报方法，终端对一个或多个频域资源(第一频域资源)对应的上报量进行压缩上报，或者对每个频域资源段内的部分RB或RB组的上报量进行压缩上报。对于其它未上报第一上报量的频域资源，终端上报其与上报量的第二上报量(如相位偏移)，网络侧根据终端的上报确定整个频域资源(第三频域资源)对应的预处理因子并进行下行发送预处理。Specifically, the information reporting method provided by the embodiment of the present disclosure is a segmented phase difference compression reporting method, in which the terminal compresses and reports the reporting amount corresponding to one or more frequency domain resources (first frequency domain resources), or compresses and reports the reporting amount of some RBs or RB groups within each frequency domain resource segment. For other frequency domain resources that do not report the first reporting amount, the terminal reports a second reporting amount (such as a phase offset) that is different from the reported amount. The network side determines the preprocessing factor corresponding to the entire frequency domain resource (third frequency domain resource) based on the terminal's report and performs downlink transmission preprocessing.

上述步骤102中向网络侧设备上报所述频域基向量及所述合并系数的实现方式包括：基于所述目标粒度，向所述网络侧设备上报所述频域基向量及所述合并系数。由于目标粒度小于或等于协议中预先规定的CSI上报粒度，能够提高反馈精度。The implementation method of reporting the frequency domain basis vectors and the combining coefficients to the network-side device in step 102 includes: reporting the frequency domain basis vectors and the combining coefficients to the network-side device based on the target granularity. Since the target granularity is less than or equal to the CSI reporting granularity predefined in the protocol, feedback accuracy can be improved.

终端在第一频域资源内根据目标粒度进行第一上报量压缩上报，其中目标粒度与CSI上报(相关协议中)的子带尺寸(第一粒度)不同。基向量长度确定方法：基向量长度由第一频域资源的尺寸和目标粒度确定。合并系数确定方法与相关技术一致。The terminal compresses and reports the first reporting amount within the first frequency domain resource according to the target granularity, where the target granularity is different from the subband size (first granularity) of the CSI reporting (in the relevant protocol). Basis vector length determination method: The basis vector length is determined by the size of the first frequency domain resource and the target granularity. The method for determining the combining coefficient is consistent with the relevant technology.

在一些实施例中，终端上报其它频域资源的起始RB或RB组(或者目标粒度对应的起始RB组)与终端上报的第一频域资源的起始RB(或起始RB组)之间的相位偏移(第二上报量，用于其它资源的下行发送预处理)。在一些实施例中，终端上报一个或多个第一频域资源的索引。In some embodiments, the terminal reports a phase offset (a second reporting amount, used for downlink transmission preprocessing of other resources) between the starting RB or RB group of other frequency domain resources (or the starting RB group corresponding to the target granularity) and the starting RB (or starting RB group) of the first frequency domain resource reported by the terminal. In some embodiments, the terminal reports the indexes of one or more first frequency domain resources.

在一些实施例中，目标粒度的确定方法可以包括以下至少一项：In some embodiments, a method for determining the target particle size may include at least one of the following:

Option 1：终端根据测量值的相关性确定目标粒度，如根据测量值组成的向量的内积，或者测量值变化值确定相关性；Option 1: The terminal determines the target granularity based on the correlation of the measured values, such as the inner product of the vector composed of the measured values or the change value of the measured values.

Option 2：终端可以根据测量的时延差以及预定义的规则(协议中规定时延差与目标粒度的对应关系)的数值确定目标粒度；Option 2: The terminal can determine the target granularity based on the measured delay difference and the value of a predefined rule (the corresponding relationship between delay difference and target granularity specified in the protocol);

Option 3：终端根据网络侧的配置或预定义的规则确定目标粒度。Option 3: The terminal determines the target granularity based on the network configuration or predefined rules.

在一些实施例中，第一频域资源可以是以下至少一种：In some embodiments, the first frequency domain resource may be at least one of the following:

1)CQI质量(或SINR质量)最好的一个或多个第一子带(例如需要通过CJT码本反馈来衡量)或终端选定的一个或多个第一子带或多个RB或多个RB组；1) One or more first subbands with the best CQI quality (or SINR quality) (e.g., measured by CJT codebook feedback) or one or more first subbands or multiple RBs or multiple RB groups selected by the terminal;

2)带宽中间的一个或多个第一子带、或多个RB或多个RB组；2) one or more first subbands, or multiple RBs, or multiple RB groups in the middle of the bandwidth;

3)具有最大长度的子带(如，不是最后一个子带)、或多个RB或多个RB组；3) a subband with the maximum length (e.g., not the last subband), or multiple RBs or multiple RB groups;

4)网络侧配置的多个子带索引或多个RB或多个RB组。4) Multiple subband indices or multiple RBs or multiple RB groups configured on the network side.

在一些实施例中，终端上报第一频域资源对应的相位差。在进行上报时，按照目标粒度对上报进行上量报(上报量包含基向量，合并系数等)，网络侧在获得终端的上报后，使用这组上报量对终端的第三频域资源对应的传输进行发送相位调整。其中第三频域资源可以是终端的整个传输带宽，第三频域资源的带宽大于第一频域资源(即上报对应的资源)，或第三频域资源包含的RB数大于第一频域资源对应的RB数。In some embodiments, the terminal reports the phase difference corresponding to the first frequency domain resource. When reporting, the report is reported according to the target granularity (the reported amount includes basis vectors, combining coefficients, etc.). After obtaining the report from the terminal, the network side uses this set of reported amounts to adjust the transmission phase corresponding to the third frequency domain resource of the terminal. The third frequency domain resource can be the entire transmission bandwidth of the terminal, the bandwidth of the third frequency domain resource is greater than the first frequency domain resource (i.e., the resource corresponding to the report), or the number of RBs included in the third frequency domain resource is greater than the number of RBs corresponding to the first frequency domain resource.

其中，第一子带为当前协议定义的子带，也即其它CSI反馈(如基于Type I码本、Type II码本、CJT码本等的PMI上报，RI上报，CQI上报等)时使用的子带。终端针对每个子带上报一个PMI、CQI等。子带的尺寸(即包含的PRB个数)由协议预先规定，如表1所示。例如，当BWP对应的PRB个数为145-275PRB时，子带size可以被配置为16个PRB或32个PRB，即16个PRB或32个PRB对应相同的预编码矩阵。子带的尺寸也可以被称为CSI上报的粒度，在本公开中，CSI上报的粒度也被称为第一粒度。Among them, the first subband is the subband defined by the current protocol, that is, the subband used for other CSI feedback (such as PMI reporting, RI reporting, CQI reporting, etc. based on Type I codebook, Type II codebook, CJT codebook, etc.). The terminal reports a PMI, CQI, etc. for each subband. The size of the subband (that is, the number of PRBs contained) is pre-defined by the protocol, as shown in Table 1. For example, when the number of PRBs corresponding to the BWP is 145-275 PRBs, the subband size can be configured as 16 PRBs or 32 PRBs, that is, 16 PRBs or 32 PRBs correspond to the same precoding matrix. The size of the subband can also be referred to as the granularity of the CSI report. In this disclosure, the granularity of the CSI report is also referred to as the first granularity.

表1：可以配置的子带尺寸
Table 1: Configurable subband sizes

相位差以压缩的方式进行上报，对应的上报粒度为目标粒度，如包含K个PRB。数值K可以由网络侧配置或者终端上报，其中第一子带尺寸可以是K的整数倍。如除相位差外的CSI上报的子带大小是32个PRB，而相位差的上报粒度K可以是4个PRB或2个PRB等。以目标粒度上报的上报量(第一上报量，相位差)是为了解决系统中的时间不同步或用于消除互易性误差，进而提升PDSCH传输性能，因此第一上报量的上报与PDSCH传输对应的CQI，PMI，RI等的上报是同时进行的，因此需要对不同上报量的上报粒度进行区分。The phase difference is reported in a compressed manner, and the corresponding reporting granularity is the target granularity, such as K PRBs. The value K can be configured by the network side or reported by the terminal, where the first subband size can be an integer multiple of K. For example, the subband size of the CSI report excluding the phase difference is 32 PRBs, and the reporting granularity K of the phase difference can be 4 PRBs or 2 PRBs, etc. The reporting amount (first reporting amount, phase difference) reported at the target granularity is to solve the time asynchrony in the system or to eliminate reciprocity errors, thereby improving the PDSCH transmission performance. Therefore, the reporting of the first reporting amount is carried out simultaneously with the reporting of CQI, PMI, RI, etc. corresponding to the PDSCH transmission. Therefore, it is necessary to distinguish the reporting granularity of different reporting amounts.

例如，当BWP内具有200个PRB(对应第三频域资源)时，终端可以上报72个PRB(对应第一频域资源)对应的相位差。在对72个PRB进行相位差上报时，终端可以测得至多72个PRB对应的相位差，终端对至多72个相位差进行压缩上报。For example, when there are 200 PRBs in the BWP (corresponding to the third frequency domain resource), the terminal can report the phase difference corresponding to 72 PRBs (corresponding to the first frequency domain resource). When reporting the phase difference for 72 PRBs, the terminal can measure the phase difference corresponding to up to 72 PRBs, and the terminal compresses and reports up to 72 phase differences.

在一些实施例中，具体的压缩上报过程可以包括：In some embodiments, the specific compression reporting process may include:

Step 1：终端对第一频域资源对应的测量资源进行测量，获得相位差，所述相位差用于反映时间同步误差或互易性误差。Step 1: The terminal measures the measurement resource corresponding to the first frequency domain resource to obtain a phase difference, which is used to reflect the time synchronization error or reciprocity error.

例如第一频域资源对应的测量资源为CSI-RS资源、TRS资源或SSB资源等。For example, the measurement resource corresponding to the first frequency domain resource is a CSI-RS resource, a TRS resource, or an SSB resource.

当进行时间误差测量时，终端可以根据网络侧配置的参考定时(如其中一个测量资源的QCL-Type A参数，即类型A参数，包括多普勒频域、多普勒扩展、平均时延和时延扩展参数)进行接收，测量每2个频域单元(每个频域单元对应一个或多个RB，或一个或多个子载波)间的相位差。以2个RB的相位差为例，假设有4个TRP，每个TRP对应一个测量资源或一个测量资源端口，终端根据测量TRP i对应的2个RB测量到的频域信道信息分别为和(假设终端使用一根接收天线进行测量，和均为标量)，则TRP i处相邻2个RB的相位差为或其中angle(·)为取相位操作。假如相邻2个RB的相位分别是和则相位差可以是 When performing time error measurement, the terminal can receive according to the reference timing configured by the network side (such as the QCL-Type A parameters of one of the measurement resources, that is, the Type A parameters, including Doppler frequency domain, Doppler spread, average delay and delay spread parameters), and measure the phase difference between each two frequency domain units (each frequency domain unit corresponds to one or more RBs, or one or more subcarriers). Taking the phase difference of 2 RBs as an example, assuming that there are 4 TRPs, each TRP corresponds to a measurement resource or a measurement resource port, the frequency domain channel information measured by the terminal based on the 2 RBs corresponding to the measurement TRP i is respectively and (Assuming the terminal uses one receiving antenna for measurement, and are all scalars), then the phase difference between two adjacent RBs at TRP i is or Where angle(·) is the phase operation. If the phases of two adjacent RBs are and Then the phase difference can be

又或者，针对每个频域单元，终端测量多个TRP(测量资源或测量资源端口)之间频域信道的相位差，如TRP i和TRP j在一个RB的频域信道信息分别为和(假设终端使用一根接收天线进行测量，和均为标量)，则TRP i和TRP j的相位差为或其中angle(·)为取相位操作。假如2个TRP的相位分别是和则相位差可以是 Alternatively, for each frequency domain unit, the terminal measures the phase difference of the frequency domain channel between multiple TRPs (measurement resources or measurement resource ports), such as the frequency domain channel information of TRP i and TRP j in one RB are respectively and (Assuming the terminal uses one receiving antenna for measurement, and are all scalars), then the phase difference between TRP i and TRP j is or Where angle(·) is the phase operation. If the phases of the two TRPs are and Then the phase difference can be

当进行互易性误差测量时，仍然以4个TRP为例，每个TRP对应一个测量资源或一个测量资源端口，终端在每个频域单元上测量2个TRP对应的测量资源的频域信道间的相位差，例如TRP 1和TRP 2的频域信道信息分别为H1和H2(假设终端使用一根接收天线进行测量，H1和H2均为标量)，表示则相位差为angle(H1/H2)或angle(H2/H1)；假如相邻2个RB的相位分别是和则相位差可以是 When performing reciprocity error measurement, we still take 4 TRPs as an example. Each TRP corresponds to a measurement resource or a measurement resource port. The terminal measures the phase difference between the frequency domain channels of the measurement resources corresponding to the two TRPs in each frequency domain unit. For example, the frequency domain channel information of TRP 1 and TRP 2 are H 1 and H 2 respectively (assuming that the terminal uses one receiving antenna for measurement, H 1 and H 2 are both scalars), and the phase difference is angle(H 1 /H 2 ) or angle(H 2 /H 1 ); if the phases of two adjacent RBs are respectively and Then the phase difference can be

此外，本公开中的方法对其它上报量的压缩上报也是适用的，其它上报量可以是频率差、时延差、自相关系数等。In addition, the method disclosed in the present invention is also applicable to the compressed reporting of other reported quantities, which may be frequency difference, delay difference, autocorrelation coefficient, etc.

其中，第一频域资源可以是以下至少一种：The first frequency domain resource may be at least one of the following:

CQI质量(或SINR质量)最好的一个或多个第一子带(例如需要通过CJT码本反馈来衡量)或终端选定的一个或多个第一子带或多个RB或多个RB组；One or more first subbands with the best CQI quality (or SINR quality) (for example, measured by CJT codebook feedback) or one or more first subbands or multiple RBs or multiple RB groups selected by the terminal;

带宽中间的一个或多个第一子带、或多个RB或多个RB组；One or more first subbands, or multiple RBs, or multiple RB groups in the middle of the bandwidth;

具有最大长度的子带(如，不是最后一个子带)、或多个RB或多个RB组；The subband with the maximum length (e.g., not the last subband), or multiple RBs or multiple RB groups;

网络侧配置的多个子带索引或多个RB或多个RB组。Multiple subband indices or multiple RBs or multiple RB groups configured on the network side.

Step 2：终端获取目标粒度，确定基向量长度。Step 2: The terminal obtains the target granularity and determines the length of the basis vector.

在一些实施例中，目标粒度的确定方法包括以下至少一项：In some embodiments, the method for determining the target particle size includes at least one of the following:

方法一：终端可以根据step 1中测量的相位差的相关性确定目标粒度。假设step 1中终端计算每个RB的相位差，如果多个RB(如T个)的测量值组成的向量的内积、也即相关性大于某个门限值，则终端确定多个RB可以联合进行相位差上报，则目标粒度可以为T个RB，或大于T个RB。如果T个RB的测量值组成的向量的内积小于某个门限值，则终端确定目标粒度小于T个RB。又或者，终端根据多个RB内的测量值的相位变化确定相关性，如果T个RB内第一个测量值(对应较低的RB索引或子载波编号)和最后一个测量值(对应较高的RB索引或子载波编号)之间的相位变化超过某个门限值，则认为二者不相关，目标粒度小于T个RB；如果T个RB内第一个测量值和最后一个测量值之间的相位变化小于某个门限值，则认为二者相关，目标粒度可以大于或等于T个RB。Method 1: The terminal can determine the target granularity based on the correlation of the phase differences measured in step 1. Assuming that in step 1, the terminal calculates the phase difference for each RB. If the inner product of the vectors composed of the measured values for multiple RBs (e.g., T), i.e., the correlation, is greater than a threshold, the terminal determines that the multiple RBs can be jointly reported for phase difference reporting. The target granularity can be T RBs or greater. If the inner product of the vectors composed of the measured values for T RBs is less than a threshold, the terminal determines that the target granularity is less than T RBs. Alternatively, the terminal can determine the correlation based on the phase variation of the measured values within multiple RBs. If the phase variation between the first measured value (corresponding to a lower RB index or subcarrier number) and the last measured value (corresponding to a higher RB index or subcarrier number) within T RBs exceeds a threshold, the two values are considered uncorrelated, and the target granularity is less than T RBs. If the phase variation between the first and last measured values within T RBs is less than a threshold, the two values are considered correlated, and the target granularity can be greater than or equal to T RBs.

方法二：终端可以根据测量的时延差的数值确定目标粒度。例如，终端根据2个测量资源确定2个TRP间的时延差为τ，则可以进一步根据的τ取值确定目标粒度，如根据表2确定。如τ值越小，目标粒度可以稍大，τ值越大，则目标粒度越小。表3给出了一个示例。Method 2: The terminal can determine the target granularity based on the measured delay difference. For example, if the terminal determines the delay difference between two TRPs as τ based on two measurement resources, the terminal can further determine the target granularity based on the value of τ, as shown in Table 2. For smaller τ values, the target granularity can be slightly larger; for larger τ values, the target granularity is smaller. Table 3 provides an example.

表2
Table 2

表3
Table 3

方法三：终端根据网络侧的配置或预定义的规则确定目标粒度。如目标粒度通过高层参数配置给终端，又或者，当网络侧配置终端进行时间误差或互易性误差测量上报时，终端确定目标粒度为T个RB。Method 3: The terminal determines the target granularity based on network configuration or predefined rules. For example, if the target granularity is configured for the terminal via high-layer parameters, or if the network configures the terminal to measure and report time error or reciprocity error, the terminal determines the target granularity to be T RBs.

在方法一和方法二中，当根据多个TRP(测量资源)确定的目标粒度不同时，终端将多个TRP对应的粒度最小值作为目标粒度，以保证所有TRP的测量量均能被准确地压缩和上报。In method one and method two, when the target granularity determined based on multiple TRPs (measurement resources) is different, the terminal uses the minimum granularity corresponding to multiple TRPs as the target granularity to ensure that the measurement quantities of all TRPs can be accurately compressed and reported.

基向量长度确定方法：基向量长度由第一频域资源和目标粒度决定。如第一频域资源包含P1个RB，目标粒度包含T个RB，则基向量的长度可以是P1/T。Method for determining the length of the basis vector: The length of the basis vector is determined by the first frequency domain resource and the target granularity. For example, if the first frequency domain resource includes P1 RBs and the target granularity includes T RBs, the length of the basis vector can be P1 /T.

在一些实施例中，基向量长度还和每个子带上报的上报量个数有关。假设一个子带上报P个上报量，P由高层参数配置或根据预定义的规则确定)，则基向量的长度为第一频域资源内需要上报的上报量个数，如PP1/T。In some embodiments, the length of the basis vector is also related to the number of reported quantities reported in each subband. Assuming that a subband reports P reported quantities, where P is configured by a higher-layer parameter or determined according to a predefined rule, the length of the basis vector is the number of reported quantities that need to be reported in the first frequency domain resource, such as PP 1 /T.

Step 3：终端根据第一频域资源的尺寸，确定第一频域资源对应的频域基向量和合并系数Step 3: The terminal determines the frequency domain basis vector and combining coefficient corresponding to the first frequency domain resource based on the size of the first frequency domain resource.

Step 4：终端向网络侧设备上报所述频域基向量及所述合并系数。Step 4: The terminal reports the frequency domain basis vector and the combining coefficient to the network side device.

在一些实施例中，终端上报第三频域资源内其它子带或频域资源(除第一频域资源外的资源)的起始RB(或者起始RB组)与终端上报的第一频域资源的起始RB(或起始RB组)之间的相位偏移。该相位偏移用于第三频域资源的相位预处理。In some embodiments, the terminal reports a phase offset between the starting RB (or starting RB group) of other subbands or frequency domain resources (resources other than the first frequency domain resources) within the third frequency domain resource and the starting RB (or starting RB group) of the first frequency domain resource reported by the terminal. This phase offset is used for phase preprocessing of the third frequency domain resource.

图3是本公开实施例提供的将一段连续的频域资源对应上报量进行压缩上报的示意图之一，如图3所示，网格部分表示第一频域资源，终端仅上报第一频域资源对应的相位差，在网络侧进行预补偿时，首先根据第一频域资源的相位差推算出其它资源的相位差。假设各段相位差的稀疏特性一致，根据时延差和相位差的对应关系，相同时延差引起的各个子载波的相位为其中为子载波k的频率，τ为对应的时延。根据公式可以看到，第三频域资源的其它资源与终端上报的第一频域资源的相位(差)是存在相位偏移的。终端可以在压缩前根据测量的相位(差)确定各段(每段对应一个或多个子带，或一个或多个RB或RB组)与上报的第一频域资源的起始位置的相位差(偏移)。其中，每个相位偏移可以以4比特进行量化。在确定第一频域资源后，终端确定其它频域资源段包含的RB数与第一频域资源相同，或小于第一频域资源的RB数(如最后一段资源的RB数小于第一频域资源的RB数，其它段资源的RB数等于第一频域资源的RB数)。FIG3 is one of the schematic diagrams of compressing and reporting the reporting amount corresponding to a continuous frequency domain resource provided by the embodiment of the present disclosure. As shown in FIG3, the grid portion represents the first frequency domain resource. The terminal only reports the phase difference corresponding to the first frequency domain resource. When pre-compensation is performed on the network side, the phase difference of other resources is first calculated based on the phase difference of the first frequency domain resource. Assuming that the sparse characteristics of the phase difference of each segment are consistent, according to the corresponding relationship between the delay difference and the phase difference, the phase of each subcarrier caused by the same delay difference is Wherein is the frequency of subcarrier k, and τ is the corresponding delay. According to the formula, it can be seen that there is a phase offset between the phase (difference) of other resources of the third frequency domain resources and the first frequency domain resources reported by the terminal. The terminal can determine the phase difference (offset) between each segment (each segment corresponds to one or more subbands, or one or more RBs or RB groups) and the starting position of the reported first frequency domain resource based on the measured phase (difference) before compression. Among them, each phase offset can be quantized with 4 bits. After determining the first frequency domain resource, the terminal determines that the number of RBs contained in other frequency domain resource segments is the same as that of the first frequency domain resource, or is less than the number of RBs of the first frequency domain resource (such as the number of RBs of the last segment of resources is less than the number of RBs of the first frequency domain resource, and the number of RBs of other segment resources is equal to the number of RBs of the first frequency domain resource).

以上分段方法由网络侧预先配置，或者终端根据预定义规则确定，或者由终端确定分段方法并上报给网络侧。The above segmentation methods are pre-configured by the network side, or determined by the terminal according to predefined rules, or determined by the terminal and reported to the network side.

一、基于网络侧配置的分段方法。1. Segmentation method based on network side configuration.

例如，网络侧配置分段时，将第三频域资源(测量资源对应的频域资源)分为O段，如网络侧将O的数值，以及每段的起始RB指示给终端。For example, when the network side configures segmentation, the third frequency domain resource (the frequency domain resource corresponding to the measurement resource) is divided into O segments, and the network side indicates the value of O and the starting RB of each segment to the terminal.

或者，网络侧将第一频域资源指示给终端，由终端确定其它分段的频域资源，例如将第一频域资源的起始RB和持续RB数，或者第一频域资源的起始第一子带编号和持续的第一子带数量指示给终端，或者以RB或第一子带为粒度通过比特映射的方式指示终端，终端在确定第一频域资源后，确定其它分段的方法包括以下至少一种：Alternatively, the network side indicates the first frequency domain resource to the terminal, and the terminal determines the frequency domain resources of other segments, for example, the starting RB and the number of continuous RBs of the first frequency domain resource, or the starting first subband number and the number of continuous first subbands of the first frequency domain resource are indicated to the terminal, or the terminal is indicated by bit mapping with RB or first subband as the granularity. After determining the first frequency domain resource, the terminal determines the method for determining other segments including at least one of the following:

1)根据第一频域资源的RB数或第一子带数确定其它分段的持续RB数或第一子带数，如其它分段的RB数或第一子带数小于等于第一频域资源的RB数或第一子带数；又例如，除最后一段为，其它分别包含的RB数或第一子带数等于第一频域资源的RB数或第一子带数，最后一段包含的RB数或第一子带数小于第一频域资源的RB数或第一子带数。1) Determine the number of continuous RBs or first subbands of other segments based on the number of RBs or the first subband of the first frequency domain resources, such as the number of RBs or the first subband of other segments is less than or equal to the number of RBs or the first subband of the first frequency domain resources; for example, except for the last segment, the number of RBs or the first subband of the other segments is equal to the number of RBs or the first subband of the first frequency domain resources, and the number of RBs or the first subband of the last segment is less than the number of RBs or the first subband of the first frequency domain resources.

2)根据第一频域资源的RB数或第一子带数确定分段数O，例如， 其中O1和O2分别为第一频域资源包含的RB数或第一子带数，和第三频域资源包含的RB数或第一子带数，为上取整操作。2) Determine the number of segments O according to the number of RBs or the number of first subbands of the first frequency domain resource, for example, Wherein O1 and O2 are respectively the number of RBs or the number of first subbands included in the first frequency domain resource and the number of RBs or the number of first subbands included in the third frequency domain resource. This is a rounding operation.

3)根据第一频域资源的RB数或第一子带数O2确定其它分段的起始RB索引或起始第一子带索引，如其它分段的起始RB索引或起始第一子带索引为tO2，其中t为非负整数或正整数。3) Determine the starting RB index or the starting first subband index of other segments according to the RB number or the first subband number O2 of the first frequency domain resource, for example, the starting RB index or the starting first subband index of other segments is tO2 , where t is a non-negative integer or a positive integer.

基于预定义规则的分段方法：Segmentation methods based on predefined rules:

在本公开中，第一频域资源和其它频域资源均由终端根据预定义的规则确定，如协议中预先规定分段数量O和/或每段包含的RB数或第一子带数，例如分段方法和第一子带划分方法类似，见表4和表5。In the present disclosure, the first frequency domain resources and other frequency domain resources are determined by the terminal according to predefined rules, such as the number of segments O and/or the number of RBs or the number of first subbands contained in each segment pre-specified in the protocol. For example, the segmentation method is similar to the first subband division method, see Table 4 and Table 5.

表4第三频域资源尺寸对应的每段包含的RB数或第一子带数
Table 4 Number of RBs or first subbands contained in each segment corresponding to the third frequency domain resource size

表5第三频域资源尺寸对应的分段数

Table 5 Number of segments corresponding to the third frequency domain resource size

终端根据预定义的每段包含的RB数或第一子带数，或者分段数，确定每个段对应的频域资源。The terminal determines the frequency domain resources corresponding to each segment according to the predefined number of RBs or the number of first subbands contained in each segment, or the number of segments.

二、终端确定的分段方法。2. Terminal-determined segmentation method.

在本公开方法中，终端根据目标粒度确定第一频域资源的RB数或第一子带数，然后将第一频域资源的起始RB索引或起始第一子带索引指示给网络侧，在一些实施例中，终端将分段数O或第一频域资源包含的RB数或第一子带数指示给网络侧。网络侧可以采用与“基于网络侧配置的分段方法”中类似的方法确定其它频域资源(分段)的起始RB索引或起始第一子带索引、以及包含的RB数或第一子带数。如目标粒度较小时，表示终端会上报较多的相位差，为了降低基向量的长度和反馈开销，终端可以将分段数确定的多一些，仅对一段频域资源(即第一频域资源)进行上报。相应地，当目标粒度较大时，表示终端会上报较少的相位差，为了保证反馈精度，终端可以将分段数确定的多一些，仍然对一段频域资源(即第一频域资源)进行上报。In the disclosed method, the terminal determines the number of RBs or the first subband of a first frequency domain resource based on a target granularity, and then indicates the starting RB index or the starting first subband index of the first frequency domain resource to the network. In some embodiments, the terminal indicates the segment number 0 or the number of RBs or the first subband number included in the first frequency domain resource to the network. The network can use a method similar to the "Segmentation Method Based on Network Configuration" to determine the starting RB index or the starting first subband index, as well as the number of RBs or the first subband number included, for other frequency domain resources (segments). If the target granularity is small, the terminal will report more phase differences. To reduce the length of the basis vectors and feedback overhead, the terminal can determine a larger number of segments and report only for a segment of the frequency domain resource (i.e., the first frequency domain resource). Correspondingly, if the target granularity is large, the terminal will report less phase differences. To ensure feedback accuracy, the terminal can determine a larger number of segments and still report for a segment of the frequency domain resource (i.e., the first frequency domain resource).

三、网络侧预处理方法。3. Network side preprocessing method.

网络侧根据终端的频域压缩上报，恢复出第一频域资源上未压缩的相位差，如根据目标粒度、基向量长度等确定第一频域资源内的多个相位差。假设目标粒度为2个RB，则每个相位差对应2个RB的资源。The network side recovers the uncompressed phase difference on the first frequency domain resource based on the terminal's frequency domain compression report. For example, multiple phase differences within the first frequency domain resource are determined based on the target granularity, basis vector length, etc. Assuming the target granularity is 2 RBs, each phase difference corresponds to 2 RBs of resources.

网络侧对第一频域资源对应的下行传输(如PDSCH传输，或其它参考信号传输)，使用终端恢复的未压缩的相位差进行预处理(与发送信号相乘后发送，实际上，这种操作也可以看作对预编码矩阵进行了预处理，即使用未压缩的相位差与预编码矩阵相乘，形成新的发送预编码矩阵)。The network side preprocesses the downlink transmission corresponding to the first frequency domain resource (such as PDSCH transmission, or other reference signal transmission) using the uncompressed phase difference recovered by the terminal (multiplied with the transmit signal and then sent. In fact, this operation can also be regarded as preprocessing the precoding matrix, that is, using the uncompressed phase difference to multiply the precoding matrix to form a new transmit precoding matrix).

对于其它分段，使用恢复的未压缩的相位差和终端上报的相位偏移进行预处理，例如，网络侧确定其它分段的每个相位差为第一频域资源对应的未压缩的每个相位差分别乘以相位偏移；对于最后一个分段，根据第一频域资源的前N个恢复出的相位差和相位偏移确定相位差。For other segments, the recovered uncompressed phase difference and the phase offset reported by the terminal are used for preprocessing. For example, the network side determines that each phase difference of the other segments is each uncompressed phase difference corresponding to the first frequency domain resource multiplied by the phase offset; for the last segment, the phase difference is determined based on the first N recovered phase differences and phase offsets of the first frequency domain resources.

具体实施例二、终端将多段频域资源对应的相位差分别进行压缩上报。Specific embodiment 2: The terminal compresses and reports the phase differences corresponding to multiple frequency domain resources respectively.

Option 1：各频域资源采用相同的FD基，且不同频域资源的合并系数独立上报。Option 1: Each frequency domain resource uses the same FD basis, and the merging coefficients of different frequency domain resources are reported independently.

各段最强系数数值上报方法：最强系数和其它非零系数采用不同的方法进行量化，例如，其它非零系数沿用相关的量化方法进行量化(最大幅度小于1)，最强系数在区间[1,a]内对最强系数的数值量化，如a的值为1.5,2,4,10等，由协议预先定义或网络侧配置。Method for reporting the numerical value of the strongest coefficient in each segment: The strongest coefficient and other non-zero coefficients are quantized using different methods. For example, other non-zero coefficients are quantized using related quantization methods (maximum amplitude is less than 1). The strongest coefficient is quantized within the interval [1, a]. For example, the value of a is 1.5, 2, 4, 10, etc., which is pre-defined by the protocol or configured on the network side.

在一些实施例中，终端上报各段频域资源的频域基向量集合的相位偏移值(用于各个频域资源段的频域基向量集合偏移不同，但是通过上报相同的频域基向量集合以降低开销)。In some embodiments, the terminal reports the phase offset value of the frequency domain basis vector set of each frequency domain resource segment (the frequency domain basis vector set offsets for each frequency domain resource segment are different, but the same frequency domain basis vector set is reported to reduce overhead).

相位偏移值可以是相位旋转矩阵中频域基向量循环移位的数值The phase offset value can be the value of the cyclic shift of the frequency domain basis vector in the phase rotation matrix

Option 2：各频域资源采用相同的FD基，且不同频域资源的合并系数联合上报。Option 2: Each frequency domain resource uses the same FD basis, and the merging coefficients of different frequency domain resources are reported jointly.

各段最强系数数值联合上报方法包括：The joint reporting method for the strongest coefficient values of each segment includes:

终端使用所有段中幅值最大的系数进行归一化，幅值最大的系数无需上报，其它各段的最强系数均可以使用相关的幅值量化方法进行量化上报(即幅值小于1)。The terminal uses the coefficient with the largest amplitude among all segments for normalization. The coefficient with the largest amplitude does not need to be reported. The strongest coefficients of other segments can be quantized and reported using the relevant amplitude quantization method (i.e., the amplitude is less than 1).

或者，终端使用所有段中幅值最小的系数进行归一化，各个频域资源段的最强系数在区间[1,a]内量化。Alternatively, the terminal uses the coefficient with the smallest amplitude in all segments for normalization, and the strongest coefficient of each frequency domain resource segment is quantized within the interval [1, a].

Option 3：各频域资源采用不同的FD基，且不同频域资源的合并系数独立上报。Option 3: Each frequency domain resource uses a different FD basis, and the merging coefficients of different frequency domain resources are reported independently.

合并系数的上报方法与option 1是相同的。The reporting method of the merger coefficient is the same as option 1.

Option 4：各频域资源采用不同的FD基，且不同频域资源的合并系数联合上报。Option 4: Each frequency domain resource uses a different FD basis, and the merging coefficients of different frequency domain resources are reported jointly.

频域基向量集合的上报方法与option 3相同，合并系数的上报方法与option 2相同。The reporting method for the frequency domain basis vector set is the same as option 3, and the reporting method for the merging coefficient is the same as option 2.

在一些实施例中，为了保证反馈精度，终端将每段频域资源对应的相位差分别压缩后进行上报，图4是本公开实施例提供的将多段连续的频域资源对应的上报量分别进行压缩上报的示意图，如图4所示，其中频域资源分段的方法和实施例一是相同的。由于每段分别压缩，采用的基向量长度较短，相比整个测量资源联合进行压缩上报的方案，终端的处理复杂度大大降低。In some embodiments, to ensure feedback accuracy, the terminal compresses the phase difference corresponding to each frequency domain resource segment before reporting. Figure 4 is a schematic diagram of separately compressing and reporting the reported quantities corresponding to multiple consecutive frequency domain resources, as provided in an embodiment of the present disclosure. As shown in Figure 4, the method for segmenting frequency domain resources is the same as in Example 1. Because each segment is compressed separately, the length of the basis vector used is shorter, significantly reducing the processing complexity of the terminal compared to a solution that compresses and reports all measurement resources together.

在一些实施例中，可以采用以下至少一种方法进行压缩上报：In some embodiments, at least one of the following methods may be used for compression reporting:

Option 1：各频域资源采用相同的FD基，每个频域资源段的合并系数不同，且不同频域资源的合并系数独立上报。Option 1: Each frequency domain resource uses the same FD basis, the merging coefficient of each frequency domain resource segment is different, and the merging coefficients of different frequency domain resources are reported independently.

在相关技术中，由于整个频域资源整体进行压缩上报(即不分段)，终端无需上报合并系数中的最强系数(其幅度预定义为1)，仅需上报其在多个非零系数中的位置。在基于分段的上报中，各段虽然独立上报合并系数，但是假设各段的合并系数中的最强系数都是1是不合理的，因此，每个频域资源都需要分别上报最强系数的幅值和位置。In related technologies, since the entire frequency domain resource is reported in a compressed form (i.e., not segmented), the terminal does not need to report the strongest coefficient among the combined coefficients (whose amplitude is predefined as 1), and only needs to report its position among multiple non-zero coefficients. In segment-based reporting, although each segment reports the combined coefficient independently, it is unreasonable to assume that the strongest coefficient among the combined coefficients of each segment is 1. Therefore, the amplitude and position of the strongest coefficient need to be reported separately for each frequency domain resource.

在本方法中，每个上报量可以采用单层(数据流)传输，因此每段频域资源只上报一个最强系数的幅值和位置。In this method, each reported quantity can be transmitted using a single layer (data stream), so each frequency domain resource only reports the amplitude and position of one strongest coefficient.

一种上报量的上报顺序可以是：适用于所有频域资源的频域基向量上报、第一个频域资源的合并系数、第二个频域资源的合并系数、…、最后一个频域资源的合并系数。A reporting order of a reporting quantity may be: reporting of frequency domain basis vectors applicable to all frequency domain resources, combining coefficients of the first frequency domain resource, combining coefficients of the second frequency domain resource, ..., combining coefficients of the last frequency domain resource.

其中基向量长度确定方法和实施例一一致，基向量个数可以由高层信令配置，当基向量的长度为U1、基向量个数为U2时，可以使用比特，其中表示从U1个频域基向量中选出U2个频域基向量时的组合数量。如果最后一个频域资源的RB数或RB组数或第一子带数过少(如小于协议中预先定义的数值)，也可以不上报合并系数，或者以不压缩的方式上报，如终端反馈每个目标粒度对应的上报量(如相位差)，多个目标粒度对应的上报量之间不进行压缩时上报。The method for determining the length of the basis vector is consistent with that in the first embodiment. The number of basis vectors can be configured by high-layer signaling. When the length of the basis vector is U 1 and the number of basis vectors is U 2 , bits, of which Indicates the number of combinations when selecting U2 frequency domain basis vectors from U1 frequency domain basis vectors. If the number of RBs, RB groups, or first subbands of the last frequency domain resource is too small (e.g., less than the value predefined in the protocol), the merging coefficient may not be reported or may be reported in an uncompressed manner. For example, if the terminal feeds back the reported quantity (e.g., phase difference) corresponding to each target granularity, the reported quantities corresponding to multiple target granularities are not compressed.

其中合并系数的上报至少包括非零系数数值上报以及非零系数位置(即指示非零系数对应的频域基向量或空域基向量)上报，还包括最强系数数值和最强系数位置上报。The reporting of the combined coefficients includes at least reporting of non-zero coefficient values and non-zero coefficient positions (i.e., frequency domain basis vectors or spatial domain basis vectors corresponding to the non-zero coefficients), and also includes reporting of the strongest coefficient value and the strongest coefficient position.

在进行最强系数数值上报时，最强系数和其它非零系数采用不同的方法进行量化，例如，其它非零系数沿用相关的量化方法进行量化，即每个非零系数的最大幅值为1，由于最强系数数值会比其它非零数值大，因此，可以在区间[1,a]内对最强系数的数值量化，如a的值为1.5,2,4,10等，由协议预先定义或网络侧配置。When reporting the strongest coefficient value, the strongest coefficient and other non-zero coefficients are quantized using different methods. For example, other non-zero coefficients are quantized using related quantization methods, that is, the maximum amplitude of each non-zero coefficient is 1. Since the strongest coefficient value is larger than other non-zero values, the strongest coefficient value can be quantized within the interval [1, a], such as the value of a is 1.5, 2, 4, 10, etc., which is pre-defined by the protocol or configured on the network side.

每段频域资源的最强系数的位置上报和相关技术一致，终端分别上报该段频域资源的最强系数对应的空域基向量和/或频域基向量。The position reporting of the strongest coefficient of each segment of frequency domain resources is consistent with the related technology, and the terminal reports the spatial domain basis vector and/or frequency domain basis vector corresponding to the strongest coefficient of the segment of frequency domain resources respectively.

在有些情况下，各个频域资源选择的基向量可能是相同的，但是最强系数对应的频域基向量不同，在这种情况下，可以令终端额外上报各个频域资源的相位偏移值，以保证各个频域资源的基向量(包括顺序)相同，降低反馈开销。其中相位偏移值指的是相关技术中的相位旋转矩阵(也即循环移位操作)对应的指示，例如，第二个频域资源段相对第一个频域资源段的频域基向量集合向左循环移位了1次，则相位偏移值可以用-1表示，当第三个频域资源段相对第一个频域资源段的频域基向量集合向右循环移位了4次，则相位偏移值可以用+4表示；反过来也是可以的，例如向左循环移位使用正值表示，向右循环移位用负值表示。In some cases, the basis vectors selected for each frequency domain resource may be the same, but the frequency domain basis vectors corresponding to the strongest coefficients are different. In this case, the terminal can be made to additionally report the phase offset value of each frequency domain resource to ensure that the basis vectors (including the order) of each frequency domain resource are the same, thereby reducing feedback overhead. The phase offset value refers to the indication corresponding to the phase rotation matrix (i.e., the cyclic shift operation) in the relevant technology. For example, the second frequency domain resource segment is cyclically shifted to the left by 1 time relative to the frequency domain basis vector set of the first frequency domain resource segment, and the phase offset value can be represented by -1. When the third frequency domain resource segment is cyclically shifted to the right by 4 times relative to the frequency domain basis vector set of the first frequency domain resource segment, the phase offset value can be represented by +4. The reverse is also possible, for example, a positive value is used to represent a left cyclic shift, and a negative value is used to represent a right cyclic shift.

可以令第n个频域资源段为参考，其它频域资源段确定其频域基向量集合与第n个频域资源段相比偏移了几位，n的数值可以由协议预先规定或网络侧配置，或终端指示给网络侧，例如终端可以选择参考频域资源段，令其它频域资源与参考频域资源的频域基向量集合的偏移值均为正值，或者均为负值，即免去偏移数值的正负号上报，在这种情况下，参考频域资源段的索引是无需上报的，网络侧只需根据各频域资源段的相位偏移值即可恢复出各个频域资源的频域基向量集合。The nth frequency domain resource segment can be used as a reference, and other frequency domain resource segments determine how many bits their frequency domain basis vector sets are offset from the nth frequency domain resource segment. The value of n can be pre-specified by the protocol or configured on the network side, or indicated to the network side by the terminal. For example, the terminal can select the reference frequency domain resource segment, so that the offset values of the frequency domain basis vector sets of other frequency domain resources and the reference frequency domain resources are all positive values, or all negative values, that is, the reporting of the positive and negative signs of the offset values is eliminated. In this case, the index of the reference frequency domain resource segment does not need to be reported, and the network side only needs to restore the frequency domain basis vector set of each frequency domain resource based on the phase offset value of each frequency domain resource segment.

Option 2：各频域资源采用相同的FD基，每个频域资源段的合并系数不同，且不同频域资源的合并系数联合上报。Option 2: Each frequency domain resource uses the same FD basis, the merging coefficient of each frequency domain resource segment is different, and the merging coefficients of different frequency domain resources are reported jointly.

其中上报量的上报顺序和方法一是类似的。在进行合并系数上报时，终端可以对各个频域资源段的非零系数联合处理，如使用所有段中幅值最大的系数进行归一化，以使得各个频域资源段的最强合并系数均能小于等于1。在这种情况下，各段的最强系数均可以使用相关的幅值量化方法进行量化上报。关于所有段中幅值最大的系数，终端可以上报数值1对应的幅值索引(如3比特量化时对应索引7，4比特量化时对应索引15)，也可以不上报幅值索引，但是上报幅值最大的最强系数对应的频域资源段的索引。The reporting order of the reported quantities is similar to that of method 1. When reporting the combined coefficients, the terminal can jointly process the non-zero coefficients of each frequency domain resource segment, such as using the coefficient with the largest amplitude in all segments for normalization, so that the strongest combined coefficient of each frequency domain resource segment can be less than or equal to 1. In this case, the strongest coefficient of each segment can be quantized and reported using the relevant amplitude quantization method. Regarding the coefficient with the largest amplitude in all segments, the terminal can report the amplitude index corresponding to the value 1 (such as index 7 for 3-bit quantization and index 15 for 4-bit quantization), or it may not report the amplitude index, but report the index of the frequency domain resource segment corresponding to the strongest coefficient with the largest amplitude.

此外，还可以使用所有段中幅值最小的系数进行归一化，以使得各个频域资源段中除了最强系数外，其它非零系数均在数值1以内，这样可以保证其它非零系数得到充分的量化(相比使用所有段中幅值最大的系数量化的方案，其它非零系数的数值更大，精度更高)；而各个频域资源段的最强系数使用其它的方法量化，如和Option 1一致，使用大于1的数值量化，如在[1,a]范围内量化。In addition, the coefficient with the smallest amplitude in all segments can be used for normalization, so that in each frequency domain resource segment, except for the strongest coefficient, the other non-zero coefficients are all within the value of 1. This can ensure that the other non-zero coefficients are fully quantized (compared with the scheme of quantizing the coefficient with the largest amplitude in all segments, the values of other non-zero coefficients are larger and the accuracy is higher); and the strongest coefficient of each frequency domain resource segment is quantized using other methods, such as consistent with Option 1, using a numerical quantization greater than 1, such as quantization within the range of [1, a].

Option 3：各频域资源采用不同的FD基，每个频域资源段的合并系数也不同，且不同频域资源的合并系数独立上报。Option 3: Each frequency domain resource uses a different FD basis, and the merging coefficient of each frequency domain resource segment is also different, and the merging coefficients of different frequency domain resources are reported independently.

在这种方法中，终端需要上报各段频域资源对应的频域基向量集合，上报量的上报顺序可以是：一个频域资源的频域基向量集合、第二个频域资源的频域基向量集合、…、最后一个频域资源的频域基向量集合、第一个频域资源的合并系数、第二个频域资源的合并系数、…、最后一个频域资源的合并系数。In this method, the terminal needs to report the frequency domain basis vector set corresponding to each segment of frequency domain resources, and the reporting order of the reported quantity can be: the frequency domain basis vector set of one frequency domain resource, the frequency domain basis vector set of the second frequency domain resource,..., the frequency domain basis vector set of the last frequency domain resource, the merging coefficient of the first frequency domain resource, the merging coefficient of the second frequency domain resource,..., the merging coefficient of the last frequency domain resource.

合并系数的上报方法与Option 1是相同的。The reporting method of the merger coefficient is the same as Option 1.

Option 4：各频域资源采用不同的FD基，每个频域资源段的合并系数也不同，且不同频域资源的合并系数联合上报；Option 4: Each frequency domain resource uses a different FD basis, and the merging coefficients of each frequency domain resource segment are also different. The merging coefficients of different frequency domain resources are reported jointly.

在本方法中，频域基向量集合的上报方法与Option 3相同，合并系数的上报方法与Option 2相同。In this method, the reporting method of the frequency domain basis vector set is the same as Option 3, and the reporting method of the merging coefficient is the same as Option 2.

在一些实施例中，网络侧预处理方法包括：In some embodiments, the network-side preprocessing method includes:

网络侧根据终端的频域压缩上报，恢复每个频域资源段上未压缩的相位差，如根据目标粒度、基向量长度等确定每个频域资源内的多个相位差。假设目标粒度为2个RB，则每个相位差对应2个RB的资源；The network side recovers the uncompressed phase difference on each frequency domain resource segment based on the frequency domain compression report of the terminal. For example, multiple phase differences within each frequency domain resource are determined based on the target granularity, basis vector length, etc. Assuming the target granularity is 2 RBs, each phase difference corresponds to 2 RBs of resources.

网络侧对每个域资源对应的下行传输(如PDSCH传输，或其它参考信号传输)，使用终端恢复的未压缩的相位差进行预处理(与发送信号相乘后发送，实际上，这种操作也可以看作对预编码矩阵进行了预处理，即使用未压缩的相位差与预编码矩阵相乘，形成新的发送预编码矩阵)。The network side pre-processes the downlink transmission corresponding to each domain resource (such as PDSCH transmission or other reference signal transmission) using the uncompressed phase difference recovered by the terminal (multiplied with the transmit signal and then sent. In fact, this operation can also be regarded as pre-processing the precoding matrix, that is, using the uncompressed phase difference to multiply the precoding matrix to form a new transmit precoding matrix).

当不同TRP均采用分段上报时，在同一个频域分段内不同TRP对应的上报量可以采用以下至少一种方法进行上报：When different TRPs are reported in segments, the reported quantities corresponding to different TRPs in the same frequency domain segment can be reported using at least one of the following methods:

Option 1：各TRP(测量资源)对应的上报量采用相同的FD基，且不同TRP(测量资源)的合并系数独立上报。Option 1: The reported quantities corresponding to each TRP (measurement resource) use the same FD basis, and the merging coefficients of different TRPs (measurement resources) are reported independently.

Option 2：各TRP(测量资源)对应的上报量采用相同的FD基，且不同TRP(测量资源)的合并系数联合上报。Option 2: The reported quantity corresponding to each TRP (measurement resource) uses the same FD basis, and the merging coefficients of different TRPs (measurement resources) are reported jointly.

Option 3：各TRP(测量资源)对应的上报量采用不同的FD基，且不同TRP(测量资源)的合并系数独立上报。Option 3: The reported quantity corresponding to each TRP (measurement resource) uses a different FD basis, and the merging coefficients of different TRPs (measurement resources) are reported independently.

Option 4：各TRP(测量资源)对应的上报量采用不同的FD基，且不同TRP(测量资源)的合并系数联合上报。Option 4: The reported quantity corresponding to each TRP (measurement resource) uses a different FD basis, and the merging coefficients of different TRPs (measurement resources) are reported jointly.

具体实施例三、终端对多段频域资源中的多个目标RB或目标RB组进行相位差压缩上报。Specific embodiment three: The terminal compresses and reports the phase difference of multiple target RBs or target RB groups in multiple frequency domain resources.

通过间隔地选择一些频域资源进行上报量压缩上报。网络侧或终端选定的目标RB或目标RB组的指示方法包括以下至少一项：The method for indicating the target RB or target RB group selected by the network side or the terminal includes at least one of the following:

1)指示起始RB或RB组的索引(相对于测量带宽起始RB的偏移，或者相对于CRB的偏移)；1) Indicates the index of the starting RB or RB group (the offset relative to the starting RB of the measurement bandwidth, or the offset relative to the CRB);

2)指示RB或RB组间隔(与目标粒度不同，可以是目标粒度的整数倍)；2) Indicates the RB or RB group interval (different from the target granularity, which can be an integer multiple of the target granularity);

3)终端会上报一个相位差适用的RB或RB组(如目标粒度)。3) The terminal reports an RB or RB group to which the phase difference applies (eg, target granularity).

其中上报量对应的频域资源可以是网络侧配置的或协议预先规定的。The frequency domain resources corresponding to the reported amount may be configured on the network side or pre-specified by the protocol.

网络侧配置终端针对每个频域资源段内的第n个RB组进行上报。The network side configures the terminal to report on the nth RB group in each frequency domain resource segment.

网络侧配置上报的RB组相关信息为以下至少一种：The RB group information reported by the network side is at least one of the following:

起始RB或RB组的索引(相对于测量带宽起始RB的索引，或者相对于CRB的索引)；Index of the starting RB or RB group (relative to the index of the starting RB of the measurement bandwidth, or relative to the index of the CRB);

每2个频域资源段选中的目标RB组之间的频域间隔(即RB数，与目标粒度不同，可以是目标粒度的整数倍)；The frequency domain spacing between target RB groups selected for every two frequency domain resource segments (i.e., the number of RBs, which is different from the target granularity and can be an integer multiple of the target granularity);

或者协议中预先规定令终端针对每个频域资源段内的第n个RB组进行上报。Alternatively, the protocol predetermines that the terminal should report on the nth RB group in each frequency domain resource segment.

在一些实施例中，终端上报其它RB组与选中的目标RB组之间的相位偏移包括以下至少一种：In some embodiments, the terminal reports the phase offset between the other RB groups and the selected target RB group, including at least one of the following:

每个RB组与选中的目标RB组之间的相位偏移；The phase offset between each RB group and the selected target RB group;

相邻的RB组与选中的目标RB组之间的相位偏移，假设任意两个RB组之间的偏移值都相同，降低反馈开销。The phase offset between adjacent RB groups and the selected target RB group is assumed to be the same between any two RB groups, reducing feedback overhead.

在本实施例中，分段方法和实施例一和实施例二是一致的，终端在每个频域资源段内选择一个RB或RB组进行相位差压缩上报，其中一个RB组可以是目标粒度对应的RB数，即每个频域资源段上报一个相位差，也可以是多个目标粒度对应的RB数，即每个频域资源段上报多个相位差。In this embodiment, the segmentation method is consistent with that of Embodiment 1 and Embodiment 2. The terminal selects an RB or an RB group in each frequency domain resource segment for phase difference compression reporting. One RB group can be the number of RBs corresponding to the target granularity, that is, one phase difference is reported in each frequency domain resource segment, or it can be the number of RBs corresponding to multiple target granularities, that is, multiple phase differences are reported in each frequency domain resource segment.

图5是本公开实施例提供的间隔地选择一些频域资源进行上报量压缩上报的示意图之一，如图5所示，网格部分表示选定的RB或RB组，即进行上报量上报的RB或RB组。其中上报量对应的频域资源(即图5中的网格部分)可以是协议预先规定的，如网络侧指示终端针对每个频域资源段内的第一个RB组进行上报(此时目标粒度即为一个RB组)，或者协议中预先规定令终端针对每个频域资源段内的第一个RB组进行上报。FIG5 is a schematic diagram of one embodiment of the present disclosure for selecting frequency domain resources at intervals for compressed reporting of reported quantities. As shown in FIG5 , the grid portion represents the selected RB or RB group, i.e., the RB or RB group for which the reported quantity is reported. The frequency domain resources corresponding to the reported quantity (i.e., the grid portion in FIG5 ) may be pre-specified by the protocol, such as the network side instructing the terminal to report on the first RB group within each frequency domain resource segment (in which case the target granularity is one RB group), or the protocol pre-specifies that the terminal reports on the first RB group within each frequency domain resource segment.

又例如，当网络侧配置上报的RB组时，可以配置以下至少一种信息：起始RB或RB组的索引(相对于测量带宽起始RB的索引，或者相对于CRB的索引)，即图3中的第一个橙色段对应的RB组；或者，每2个频域资源段选中的目标RB组之间的频域间隔(即RB数，与目标粒度不同，可以是目标粒度的整数倍)。For another example, when the network side configures the reported RB group, at least one of the following information can be configured: the index of the starting RB or RB group (relative to the index of the starting RB of the measurement bandwidth, or relative to the index of the CRB), that is, the RB group corresponding to the first orange segment in Figure 3; or, the frequency domain interval between the target RB groups selected for every two frequency domain resource segments (that is, the number of RBs, which is different from the target granularity and can be an integer multiple of the target granularity).

终端在进行压缩上报时，所有频域资源段内选中的目标RB组联合进行压缩上报，压缩和上报方法和相关技术一致。When the terminal performs compression reporting, the target RB groups selected in all frequency domain resource segments are jointly compressed and reported. The compression and reporting methods are consistent with related technologies.

假设每个频域资源内选定一个目标粒度对应的RB组进行上报，且多段频域资源选定的RB组间隔是相同的，其它未进行上报的RB组与选中的目标RB组的频域特性可以是一致的，但是由于各个频域资源段的起始RB不同，绝对相位差是不同的。为了网络侧进行预处理，终端还需要上报其它RB或RB组(未选中RB或RB组)与选定的目标RB或RB组之间的相位偏移。以第一个频域资源段为例，选中的目标RB组(网格部分)与其它RB组之间的相位偏移如图6所示，图6是本公开实施例提供的上报未选中RB或RB组与选定的RB或RB组之间的相位偏移的示意图。Assuming that an RB group corresponding to a target granularity is selected in each frequency domain resource for reporting, and the intervals between RB groups selected for multiple frequency domain resources are the same, the frequency domain characteristics of other RB groups that are not reported may be consistent with those of the selected target RB group, but due to the different starting RBs of each frequency domain resource segment, the absolute phase difference is different. In order to perform preprocessing on the network side, the terminal also needs to report the phase offset between other RBs or RB groups (unselected RBs or RB groups) and the selected target RBs or RB groups. Taking the first frequency domain resource segment as an example, the phase offset between the selected target RB group (grid part) and other RB groups is shown in Figure 6, which is a schematic diagram of reporting the phase offset between the unselected RBs or RB groups and the selected RBs or RB groups provided in an embodiment of the present disclosure.

在这种方法中，终端上报的相位偏移包括以下至少一种：In this method, the phase offset reported by the terminal includes at least one of the following:

每个RB组与选中的目标RB组之间的相位偏移；The phase offset between each RB group and the selected target RB group;

相邻的RB组与选中的目标RB组之间的相位偏移，假设任意两个RB组之间的偏移值都相同，降低反馈开销。The phase offset between adjacent RB groups and the selected target RB group is assumed to be the same between any two RB groups, reducing feedback overhead.

网络侧预处理方法包括：Network-side preprocessing methods include:

网络侧根据终端的频域压缩上报，恢复出选中的目标RB组对应的未压缩的相位差，如根据目标粒度、基向量长度等确定多个相位差；The network side recovers the uncompressed phase difference corresponding to the selected target RB group based on the frequency domain compression report of the terminal, such as determining multiple phase differences based on the target granularity, basis vector length, etc.

网络侧对上报的RB组对应的下行传输(如PDSCH传输，或其它参考信号传输)，使用终端恢复的未压缩的相位差进行预处理(与发送信号相乘后发送，实际上，这种操作也可以看作对预编码矩阵进行了预处理，即使用未压缩的相位差与预编码矩阵相乘，形成新的发送预编码矩阵)；The network side pre-processes the downlink transmission (such as PDSCH transmission or other reference signal transmission) corresponding to the reported RB group using the uncompressed phase difference recovered by the terminal (multiplied with the transmit signal before transmission. In fact, this operation can also be regarded as pre-processing the precoding matrix, that is, multiplying the uncompressed phase difference with the precoding matrix to form a new transmit precoding matrix).

对于其它RB组，使用恢复的未压缩的相位差和终端上报的相位偏移进行预处理，例如，网络侧确定图6中斜线部分对应的频域资源(RB组)中的每个相位差为网格部分对应的频域资源(RB组)中的每个相位差乘以相位偏移1。For other RB groups, the recovered uncompressed phase difference and the phase offset reported by the terminal are used for preprocessing. For example, the network side determines that each phase difference in the frequency domain resources (RB group) corresponding to the oblique part in Figure 6 is each phase difference in the frequency domain resources (RB group) corresponding to the grid part multiplied by the phase offset 1.

具体实施例四、组合方案。Specific embodiment 4, combination solution.

可以考虑具体实施例一至具体实施例三中多个压缩上报方法的结合方案，例如，终端可以按照实施例三中的方法上报选定的不连续RB组内对应上报量，在上报相位偏移时，还可以对一个频域资源段内的多个上报量(相位偏移)进行压缩上报(与实施例一中的方法类似，只是上报量的物理含义不同，实施例一中的上报量可以是相位差)，如图7所示，图7是本公开实施例提供的间隔地选择一些频域资源进行上报量压缩上报的示意图之二。A combination of multiple compressed reporting methods in specific embodiments one to specific embodiments three may be considered. For example, the terminal may report the corresponding reporting amount in the selected discontinuous RB group according to the method in embodiment three. When reporting the phase offset, multiple reporting amounts (phase offsets) in a frequency domain resource segment may also be compressed and reported (similar to the method in embodiment one, except that the physical meaning of the reporting amount is different. The reporting amount in embodiment one may be a phase difference), as shown in FIG7 . FIG7 is the second schematic diagram of the intermittent selection of some frequency domain resources for compressed reporting of the reporting amount provided in the embodiment of the present disclosure.

又例如，终端可以按照实施例一中的方法上报第一频域资源对应的上报量，此外对各个相位偏移进行压缩上报(与实施例三中的方法类似，只是上报量的物理含义不同，实施例三中的上报量可以是相位差)，如图8所示，图8是本公开实施例提供的将一段连续的频域资源对应上报量进行压缩上报的示意图之二。For another example, the terminal can report the reporting amount corresponding to the first frequency domain resource according to the method in Example 1, and in addition compress and report each phase offset (similar to the method in Example 3, except that the physical meaning of the reporting amount is different, and the reporting amount in Example 3 can be a phase difference), as shown in Figure 8. Figure 8 is the second schematic diagram of compressing and reporting the reporting amount corresponding to a continuous frequency domain resource provided by an embodiment of the present disclosure.

在进行多种方法联合上报时，不同压缩上报方法(如图7中的第一上报量(相位差)上报，和第二上报量(相位偏移)上报)的频域基向量集合可能是相同的，也可能是不同的，可以采用和实施例二类似的方法上报，具体如下：When multiple methods are jointly reported, the frequency domain basis vector sets of different compressed reporting methods (such as the first reporting amount (phase difference) reporting and the second reporting amount (phase offset) reporting in Figure 7) may be the same or different, and a method similar to that of Example 2 may be used for reporting, as follows:

Option 1：第一上报量和第二上报量，上报相同的频域基向量，但合并系数不同，且不同上报量的合并系数独立上报；Option 1: The first and second reported quantities report the same frequency domain basis vectors, but different merging coefficients, and the merging coefficients of different reported quantities are reported independently;

Option 2：第一上报量和第二上报量，上报相同的频域基向量，但合并系数不同，且不同上报量的合并系数联合上报；Option 2: The first and second reported quantities report the same frequency domain basis vectors, but different merging coefficients, and the merging coefficients of different reported quantities are reported jointly;

Option 3：第一上报量和第二上报量，上报不同的频域基向量，且合并系数不同，且不同上报量的合并系数独立上报；Option 3: The first and second reported quantities report different frequency domain basis vectors and different merging coefficients, and the merging coefficients of different reported quantities are reported independently;

Option 4：第一上报量和第二上报量，上报不同的频域基向量，且合并系数不同，且不同上报量的合并系数联合上报。Option 4: The first reported quantity and the second reported quantity report different frequency domain basis vectors, and have different merging coefficients, and the merging coefficients of different reported quantities are reported jointly.

本公开实施例提供的信息上报方法中，通过终端使用目标粒度进行第一上报量上报，终端使用分段方法进行频域压缩上报，终端可以使用更短的频域基向量进行压缩上报，减小反馈的开销和/或终端处理复杂度。In the information reporting method provided by the embodiment of the present disclosure, the terminal uses the target granularity to report the first reporting amount, and the terminal uses a segmented method to perform frequency domain compression reporting. The terminal can use a shorter frequency domain basis vector for compression reporting, thereby reducing feedback overhead and/or terminal processing complexity.

具体实施例五、针对不同测量资源压缩上报。Specific embodiment 5: Compress and report different measurement resources.

具体地，多TRP联合频域压缩上报。在进行CJT传输时，除了使用具体实施例一至具体实施例四中多个压缩上报方法外，终端还需要考虑多个TRP的相位差上报，具体上报方法如下：Specifically, multiple TRPs are reported in frequency domain compression. When performing CJT transmission, in addition to using multiple compression reporting methods in specific embodiments 1 to 4, the terminal also needs to consider the phase difference reporting of multiple TRPs. The specific reporting method is as follows:

方法一：在每个RB或RB组或第一子带或第二子带内，终端测量每个测量资源(TRP)和参考测量资源(参考TRP)之间的相位差，每个TRP对应的相位差均使用具体实施例一至具体实施例四中的方法进行上报。Method 1: Within each RB or RB group or the first subband or the second subband, the terminal measures the phase difference between each measurement resource (TRP) and the reference measurement resource (reference TRP), and the phase difference corresponding to each TRP is reported using the methods in specific embodiments 1 to 4.

方法二：在每个RB或RB组或第一子带或第二子带内，终端测量每个测量资源(TRP)的不同RB之间的相位差，每个TRP对应的相位差均使用具体实施例一至具体实施例四中的方法进行上报。Method 2: Within each RB or RB group or the first subband or the second subband, the terminal measures the phase difference between different RBs of each measurement resource (TRP), and the phase difference corresponding to each TRP is reported using the methods in specific embodiments one to four.

本公开实施例提供的信息上报装置，通过使用频域资源分段的方法，第一频域资源为测量带宽内一段或多段频域资源，首先根据第一频域资源的尺寸，确定第一频域资源对应的频域基向量和合并系数，然后对第一频域资源(即分段频域资源)对应的频域基向量及合并系数进行上报，由于第一频域资源是测量带宽内一段或多段频域资源，而不是测量带宽整体，因而可以缩短频域基向量的长度，进而能够减小终端反馈开销，降低终端处理复杂度。The information reporting device provided by the embodiment of the present disclosure uses a frequency domain resource segmentation method. The first frequency domain resource is one or more frequency domain resources within the measurement bandwidth.

Then, the frequency domain basis vectors and merging coefficients corresponding to the first frequency domain resource (i.e., the segmented frequency domain resource) are reported. Since the first frequency domain resource is one or more frequency domain resources within the measurement bandwidth, rather than the entire measurement bandwidth, the length of the frequency domain basis vectors can be shortened, thereby reducing the terminal feedback overhead and the terminal processing complexity.
