In another possible design, the set of non-zero amplitude coefficients in the L sets of non-zero amplitude coefficients may also be a second time unit corresponding to the doppler domain, where a set of non-zero amplitude coefficients corresponding to a second time unit in the doppler domain is understood to be derived from the signal/channel information of the second time unit, and the value of L is equal to the number of second time units in the doppler domain. Accordingly, it can be understood that, since one second time unit corresponds to one doppler domain base vector, that is, one set of non-zero amplitude coefficients corresponds to one doppler domain base vector, and the value of L is equal to the number of doppler domain base vectors, the description of the first time unit and the second time unit is referred to the description of the foregoing embodiments, and will not be repeated herein.

In some alternative embodiments, one spatial codebook information may correspond to one reference signal resource set or one reference signal resource group or one reference signal resource, in other words, the one spatial codebook information may correspond to one first time unit in the time domain, and the value of M may be equal to the number of first time units in the time domain, that is, the value of M may be equal to the number of reference signal resource sets or reference signal resource groups or reference signal resources.

In some alternative embodiments, one frequency domain codebook information may correspond to one doppler domain base vector, in other words, one frequency domain codebook information may correspond to one second time unit of the doppler domain, and the value of N may be equal to the number of second time units on the doppler domain, that is, the value of N may be equal to the number of doppler domain base vectors. A second time unit in the doppler domain corresponds to a frequency domain codebook information, which is understood to be obtained according to the signal/channel information of the second time unit, and a second time unit corresponds to a doppler domain base vector, and accordingly, a frequency domain codebook information may also correspond to a doppler domain base vector.

In alternative embodiments, the value of N may also be equal to 1, for example, the frequency domain codebook information of all the second time units in the doppler domain is the same, i.e. all the second time units in the doppler domain share the same frequency domain codebook information. It is understood that the value of N may be other values, and the application is not limited.

Optionally, the value of the number N of the frequency codebook information in the embodiment of the present application may be smaller than or equal to the number of the reference signal resource sets or the number of the reference signal resource groups or the number of the reference signal resources. In some alternative embodiments, one frequency domain codebook information may correspond to one reference signal resource set or one reference signal resource group or one reference signal resource, in other words, the one frequency domain codebook information may correspond to one first time unit in the time domain, and the value of N may be equal to the number of first time units in the time domain, that is, the value of N may be equal to the number of reference signal resource sets or reference signal resource groups or reference signal resources. The frequency domain codebook information is obtained according to the reference signal resource set or the signal/channel information of the reference signal resource, and correspondingly, the frequency domain codebook information is obtained according to the signal/channel information of the first time unit in the time domain. In other alternative embodiments, the value of N may be equal to 1, for example, the frequency domain codebook information of all the first time units in the time domain is the same, that is, all the first time units in the time domain share the same frequency domain codebook information, in other words, all the reference signal resource sets or all the reference signal resource groups or all the spatial codebook information corresponding to the reference signal resources are the same.

The following illustrates the manner in which at least one of doppler domain information, M spatial codebook information, N frequency domain codebook information, and non-zero magnitude coefficient indicating information is carried in the second portion of the CSI report:

in a first alternative embodiment, the second portion includes first packet information (e.g., group 0), second packet information (e.g., group 1), and third packet information (e.g., group 2), where the first packet information includes at least one of doppler domain information, M spatial codebook information, N frequency domain codebook information, a strongest coefficient index, and a reference amplitude in a polarization direction different from the polarization direction in which the strongest coefficient index is located in each of L sets of non-zero amplitude coefficients; the second grouping information comprises at least one of the value of the non-zero amplitude coefficient of the highest priority in each group of non-zero amplitude coefficients in the L groups of non-zero amplitude coefficients, a first bit map corresponding to each group of non-zero amplitude coefficients in the L groups of non-zero amplitude coefficients and a reference amplitude in the polarization direction different from the polarization direction in which the strongest coefficient index is located in each group of non-zero amplitude coefficients in the L groups of non-zero amplitude coefficients; the third grouping information comprises the value of the non-zero amplitude coefficient with the lowest priority in each group of non-zero amplitude coefficients in the L groups of non-zero amplitude coefficients and a second bit map corresponding to each group of non-zero amplitude coefficients in the L groups of non-zero amplitude coefficients.

Wherein the first packet information has a higher priority than the second packet information, and the second packet information has a higher priority than the third packet information.

In a second alternative embodiment, the second portion includes common group information (e.g., group 0) and a plurality of grouping information (e.g., group 1, group 2, group 3 …, etc.). The common group information comprises at least one of Doppler domain information, M pieces of space domain codebook information and N pieces of frequency domain codebook information. The plurality of grouping information includes at least one of N frequency domain codebook information and non-zero magnitude coefficient indicating information. It is appreciated that in this embodiment, N frequency domain codebook information may be carried in common group information or in grouping information. Wherein the priority of the common group information is greater than the priority of the plurality of packet information.

In one possible implementation, the plurality of packet information may be divided into L sets of packet information. Alternatively, one set of packet information may correspond to one set of reference signal resources or one reference signal resource. Wherein, a grouping information set corresponds to a reference signal resource set or a reference signal resource group or a reference signal resource, it is understood that the information carried by each grouping information in the grouping information set may be determined according to the signal/channel information carried on the reference signal resource set or the reference signal resource group or the reference signal resource. Since a reference signal resource set or a reference signal resource group or a reference signal resource corresponds to a first time unit in the time domain, a packet information set also corresponds to a first time unit in the time domain, and a packet information set corresponds to a first time unit is understood as that the information carried by each packet information in the packet information set is determined according to the signal/channel information of the first time unit. Alternatively, a set of packet information may correspond to a doppler domain base vector, and a set of packet information corresponds to a doppler domain base vector may be understood as information carried by each packet information in the set of packet information is determined according to signal/channel information of a second time unit corresponding to the doppler domain base vector. Of course, since one doppler domain base vector corresponds to one second time unit, one set of packet information also corresponds to one second time unit.

Alternatively, the number of packet information included in each packet information set may not be limited, for example, 2 packet information, 3 packet information, or other number of packet information may be included in each packet information set, or the like. The following exemplifies that each set of packet information includes 3 pieces of packet information.

For example, each set of packet information may include first packet information, second packet information, and third packet information. Optionally, the information carried by the first packet information, the second packet information and the third packet information in the same packet information set corresponds to the same reference signal resource set or the same reference signal resource group or the same reference signal resource, and the information carried by the first packet information, the second packet information and the third packet information in the same packet information set may also be understood to correspond to the same first time unit, where the understanding about the correspondence between the packet information set and the reference signal resource set or the reference signal resource group or the reference signal resource or the first time unit may be referred to the description of the foregoing embodiments and is not repeated herein. Optionally, the information carried by the first packet information, the second packet information, and the third packet information in the same packet information set may correspond to the same doppler domain base vector, and the information carried by the first packet information, the second packet information, and the third packet information in the same packet information set may also be understood as corresponding to the same second time unit. The understanding of the correspondence between the packet information set and the doppler domain base vector or the second time unit may refer to the description of the foregoing embodiments, and will not be repeated herein.

The first grouping information may include at least one of one frequency domain codebook information of the N frequency domain codebook information, a strongest coefficient index of a set of non-zero magnitude coefficients of the L sets of non-zero magnitude coefficients, and a reference magnitude in a polarization direction different from a polarization direction in which the strongest coefficient index is located of the set of non-zero magnitude coefficients of the L sets of non-zero magnitude coefficients. The second grouping information includes at least one of a reference amplitude value in a polarization direction different from a polarization direction in which the strongest coefficient index is located in each of the L sets of non-zero amplitude coefficients, a value of a non-zero amplitude coefficient of a highest priority among a set of non-zero amplitude coefficients in the L sets of non-zero amplitude coefficients, and a first bit map corresponding to the set of non-zero amplitude coefficients. The third grouping information comprises at least one of the value of the non-zero amplitude coefficient with the lowest priority in one group of non-zero amplitude coefficients in the L groups of non-zero amplitude coefficients and a second bit map corresponding to the one group of non-zero amplitude coefficients. It will be appreciated that the "set of non-zero magnitude coefficients" referred to in the first, second and third grouping information in the same grouping information set are the same set of non-zero magnitude coefficients.

In one possible design, the first packet information has a priority greater than the second packet information, and the second packet information has a priority greater than the third packet information.

In one possible design, the first grouping information may include at least one of one frequency domain codebook information of the N frequency domain codebook information, a reference amplitude value in a polarization direction different from a polarization direction in which the strongest coefficient index is located in each of the L sets of non-zero amplitude coefficients, a strongest coefficient index of a set of non-zero amplitude coefficients of the L sets of non-zero amplitude coefficients, a value of a non-zero amplitude coefficient of a highest priority of the set of non-zero amplitude coefficients, and a first bit map corresponding to the set of non-zero amplitude coefficients. The second grouping information comprises at least one of the value of the non-zero amplitude coefficient with the lowest priority in one group of non-zero amplitude coefficients in the L groups of non-zero amplitude coefficients and a second bit map corresponding to the one group of non-zero amplitude coefficients. It can be understood that the strongest coefficient index may be placed in the second packet information, which is not limited by the present application, and the packet information bearing manner may be applicable to a packet information set including two packet information or three packet information, or may be applicable to a packet information set including other packet information, which is not limited by the present application.

It will be appreciated that 3 pieces of grouping information may be included in each grouping information set, L grouping information sets include 3*L pieces of grouping information in total, the 3*L pieces of grouping information may be sequentially numbered, for example, group 1, group 2, group 3, group 4 … group 3*L, wherein group 1, group 2 and group 3 may be the same grouping information set, group 4, group 5 and group 6 may be another grouping information set, and so on. In each grouping information set, the first grouping information, the second grouping information and the third grouping information can be sequentially arranged from small to large according to the index value of the group, and certainly, the dividing mode is only used as an example, and the first grouping information, the second grouping information and the third grouping information can be not distinguished according to the index value of the group.

For example, if the value of N is greater than 1, i.e., the CSI report includes a plurality of frequency domain codebook information, the common group information may include M spatial codebook information and doppler domain information, and the first group information in each of the L group information sets includes one frequency domain codebook information of the N frequency domain codebook information, it may be understood that the frequency domain codebook information included in the first group information in different group information sets may be different or the same. Optionally, the first grouping information in each grouping information set further includes a strongest coefficient index of a group of non-zero magnitude coefficients in the L groups of non-zero magnitude coefficients, which may be specifically referred to the description in the foregoing embodiment and will not be repeated herein.

For example, if the value of N is equal to 1 and the value of M is greater than 1, i.e., the CSI includes 1 frequency domain codebook information and a plurality of spatial codebook information, the common group information may include M spatial codebook information and doppler domain information. The frequency domain codebook information is included in the first packet information in one of the L packet information sets, and optionally, the frequency domain codebook information may not be included in the first packet information in the remaining L-1 packet information sets. It is appreciated that in some embodiments, the frequency domain codebook information may also be included in the first packet information in the remaining L-1 packet information sets, and illustratively, the first packet information in a portion of the remaining L-1 packet information sets includes the frequency domain codebook information. Optionally, the first grouping information in each grouping information set includes a strongest coefficient index of a group of non-zero magnitude coefficients in the L groups of non-zero magnitude coefficients, which may be specifically referred to the description in the foregoing embodiment and will not be repeated herein.

For example, if the value of N is equal to 1 and the value of M is greater than 1, i.e., the CSI includes 1 frequency domain codebook information and a plurality of spatial codebook information, the common group information may include at least one of M spatial codebook information, doppler domain information, and frequency domain codebook information. Optionally, the frequency domain codebook information is included in the first packet information in one of the L sets of packet information. Optionally, the first packet information in the remaining L-1 packet information sets does not include frequency domain codebook information. It is appreciated that in some embodiments, the frequency domain codebook information may also be included in the first packet information in the remaining L-1 packet information sets, and illustratively, the first packet information in a portion of the remaining L-1 packet information sets includes the frequency domain codebook information. Optionally, the first grouping information in each grouping information set includes a strongest coefficient index of a group of non-zero magnitude coefficients in the L groups of non-zero magnitude coefficients, which may be specifically referred to the description in the foregoing embodiment and will not be repeated herein.

For example, if the value of N is equal to 1 and the value of M is equal to 1, i.e., the CSI includes 1 frequency domain codebook information and 1 spatial codebook information, the common group information may include at least one of the spatial codebook information, the frequency domain codebook information, and the doppler domain information. The first grouping information in each grouping information set includes a strongest coefficient index of a set of non-zero magnitude coefficients in the L sets of non-zero magnitude coefficients.

For example, if the value of N is equal to 1 and the value of M is equal to 1 or greater than 1, i.e., the CSI includes 1 frequency domain codebook information and one or more spatial codebook information, the common group information may include at least one of the one or more spatial codebook information, the doppler domain information, and the frequency domain codebook information. Two pieces of packet information may be included in each of the L sets of packet information, for example, a first packet information and a second packet information may be included in each set of packet information.
