The first embodiment,

The embodiment of the present invention provides a method for reporting Channel State Information (CSI), which is applied to a terminal device, and as shown in fig. 2, the method includes:

step 201: determining the number of beam information contained in CSI report according to at least one preset condition;

step 202: according to the determined quantity of the beam information, CSI is reported;

wherein the at least one preset condition comprises at least one of:

triggering DCI reported by the CSI;

the transmission parameters reported by the CSI;

and reporting the corresponding physical resources by the CSI.

The number of the beam information corresponding to the beam reported by the CSI may be the number of the beam information corresponding to a part of the beams in all the beams.

By adopting the scheme, the number of the information corresponding to the partial beams in all the beams which are only reported by the terminal equipment can be determined through the preset conditions.

The following is a detailed description of the scenarios of the aforementioned several preset conditions:

scene one,

When the at least one preset condition comprises Downlink Control Information (DCI) triggering the CSI to be reported,

the determining the number of beam information included in the CSI report includes one of:

determining the number of beam information contained in the CSI report according to the RNTI adopted for CRC scrambling of the DCI;

determining the number of beam information contained in the CSI report according to the DCI format of the DCI;

and determining the number of beam information contained in the CSI report according to the indication information contained in the DCI.

The DCI may be configured to trigger a periodic CSI report or a persistent CSI report; the aperiodic report is to trigger the terminal to carry out single CSI report through DCI; the persistent CSI reporting may be quasi-persistent reporting, where the quasi-persistent reporting is to trigger the terminal to perform periodic CSI reporting through DCI or MAC signaling until receiving a deactivation signaling.

Specifically, the number of beam information included in the CSI report is determined according to a Radio Network Temporary Identity (RNTI) used for CRC scrambling of the DCI.

For example, the number of beam information included in the CSI report is determined based on whether the DCI is scrambled by the first RNTI or the second RNTI; the first RNTI and the second RNTI correspond to different amounts of beam information. The first RNTI and the second RNTI may be SP-CSI RNTI and Cell Radio Network Temporary Identifier (C-RNTI), respectively.

Assuming that the first RNTI and the second RNTI can be SP-CSI RNTI and C-RNTI, respectively, DCI scrambled by CRC using SP-CSI RNTI and DCI scrambled by CRC using C-RNTI may be different in number. Since the SP-CSI RNTI is used for quasi-persistent CSI reporting and the C-RNTI is used for aperiodic CSI reporting, different CSI reporting modes can adopt different beam information quantities, and therefore reporting accuracy and overhead can be adjusted flexibly.

The number of beam information included in the CSI report is determined according to the DCI format of the DCI, for example, the number of beam information may be different between CSI report triggered by DCI format 0_0 and CSI report triggered by DCI format 0_ 1.

And determining the number of beam information contained in the CSI report according to the indication information contained in the DCI. The indication information included in the DCI is information content included in an information field of the DCI, for example, a certain field may be preset to be used for reporting the number of beam information included in the DCI.

Specifically, the indication information of the DCI may directly include the number of beam information. The number of beams dedicated to the beam information in the DCI may be directly indicated, for example, 2 bits for 4 beams.

Or, the number of beam information included in the CSI report may be determined according to other information fields in the DCI. For example, the CSI request information field in the DCI is used to indicate a currently used CSI reporting configuration from a plurality of CSI reporting configurations, and each CSI reporting configuration may include the number of beam information. And obtaining the reporting configuration of the target CSI through the information domain, and simultaneously obtaining the quantity of beam information.

Scene two,

When the at least one preset condition includes DCI triggering the CSI report, determining the number of beam information included in the CSI report according to the DCI triggering the CSI report and the number of beam information configured by a high-level signaling.

Here two sub-scenarios are involved:

sub-scenario 1,

Selecting a value from the number of at least one beam message configured by a higher layer signaling based on the DCI, and taking the selected value as the number of the beam messages contained in the CSI report.

For example, if the candidate value of the beam information amount configured by the higher layer signaling is {2, 4}, it may indicate, through bit information in the DCI, whether the amount of beam information in the current CSI report is 2 or 4.

For example, in the above example, 1 bit may be used to indicate that a few values are selected from the candidate values as the number of reported beam information.

Sub-scenario 2,

When the number of the at least one beam information configured by the higher layer signaling is only the number of one maximum beam information:

and selecting the number of beam information contained in the CSI report from 1 to the maximum number of beam information based on the number of the maximum beam information and the DCI.

For example, the maximum number of beam information configured by the higher layer signaling is L, that is, the number of beam information that can be reported by the terminal device is any one of 1 to L, and at this time, the number of beam information can be obtained by log2(L) (rounding up) bits in DCI, where the bits are used to indicate that the number of beam information of the beam information reported by the current CSI is one of 1, 2.

For example, if the number of the maximum beam information configured by the higher layer signaling is L-4 and the information indicated in the DCI is 10, the CSI may report the beam information corresponding to the 3 beams.

Scene three, when the at least one preset condition comprises the transmission parameter reported by the CSI,

determining the number of beam information contained in CSI report according to the time slot used by the CSI report;

determining the number of beam information contained in CSI report according to the current times of CSI report;

determining the number of beam information contained in CSI report according to whether the CSI report is transmitted with data multiplexing or not;

and determining the quantity of beam information contained in the CSI report according to a bearing channel of the CSI report.

The determining, according to the time slot used for CSI reporting, the number of beam information included in the CSI report may specifically be: calculating according to the index of the time slot used for reporting the CSI and the period of reporting the CSI to obtain the number of beam information; alternatively, the correspondence between the number of the time slots and the number of the beam information may be predefined between the network side and the terminal device.

For example, assuming that the index of the timeslot is S and the period of CSI reporting is T, the terminal may determine the number L of beam information to be used according to whether the result obtained by n ═ S/T (rounding-down) is an odd number or an even number, where L is 4 for an even number and L is 2 for an odd number.

Or, on the basis of the calculation of N, further determining the number L of used beam information according to k-N mod N, wherein if k is 0, L is 4, otherwise L is 2; where N may be a default integer value and mod is a modulo operation.

The determining, according to the current number of CSI reports, the number of beam information included in the CSI report includes:

if the current CSI report is the nth report, the number L of the beam information may be determined according to the value of n. Here, n and L are both positive numbers, and the correspondence relationship may be defined in advance by the network side and the terminal. Wherein, the CSI reporting is a periodic or quasi-persistent CSI reporting.

Further, the number L of beam information can be calculated according to a preset calculation formula, the current reporting times N and a preset numerical value N; for example, k ═ N mod N may be used to determine the number L of beam information used, for example, in the obtained result, k ═ 0 and L ═ 4, otherwise, L ═ 2 and N are given integer values.

The determining the number of beam information included in the CSI report according to whether the CSI report is multiplexed with data may include: if the CSI report and the data are multiplexed in the same Channel, for example, a Physical Uplink Shared Channel (PUSCH), the number of the beam information is a first number; if the CSI report and the data are multiplexed in different channels, namely CSI is independently transmitted, the number of the beam information is a second number; wherein the first number and the second number are both integers, and the first number is less than the second number.

The determining, according to the bearer channel reported by the CSI, the number of beam information included in the CSI report may be: assuming that there are two bearer channels, the amount of corresponding beam information is determined according to whether the CSI report is the first bearer signal or the second bearer channel.

For example, if the CSI report is carried by a Physical Uplink Control CHannel (PUCCH), the number of beam information is a third number; and if the CSI report is carried by a PUSCH, the number of the beam information is a fourth number, and the third number is less than the fourth number.

Scene four,

When the at least one preset condition includes a physical resource corresponding to the CSI report,

the determining the number of beam information included in the CSI report includes: according to one of the following physical resources corresponding to the CSI report: a sub-band, a Bandwidth Part (BWP, Bandwidth Part), and a time slot, and determining the number of beam information included in the CSI report.

And when the physical resource is a sub-band, the terminal determines the quantity of the beam information according to the sub-band corresponding to the CSI report. Specifically, for the amplitude information and the phase information that need to be reported for a subband, the number of the amplitude information and the phase information of the subband may be determined according to the subband corresponding to the current CSI.

For example, for a first configured subband or a best subband selected by the terminal, the amplitude and phase information of L beams may be reported; for other subbands, only the amplitude and phase information of the M beams may be reported, where M < L.

The first subband may be determined according to the number of the subband, for example, the first subband may be a first subband in 8 subbands identified as 0 to 7, that is, subband 0 is the first subband; alternatively, the first subband in a subband group may be, for example, there may be 16 subbands that are identified as 0-15 subbands, respectively, where the assigned group of subbands is 8-15, and then the first subband may be subband 8.

In addition, the foregoing subband with the best quality may be determined according to indexes such as a transmission rate, a CQI, or an SINR, for example, the subband with the highest transmission rate, or the subband with the highest CQI, or the subband may also be determined according to a load size of the subband, and the like, and this embodiment is not exhaustive.

When the physical resource is a bandwidth part (BWP), for the beam information that needs to be reported for the BWP, the number of the beam information of the BWP may be determined according to the BWP corresponding to the current CSI report. For example, the number of beam information may be determined according to the index of BWP. Wherein, the network side may pre-configure a corresponding amount of beam information for each BWP.

When the physical resource is a time slot, the number of beam information of the time slot may be determined according to the time slot corresponding to the current CSI for the beam information that needs to be reported for the time slot. For example, CSI0 is the CSI for slot 0 and CSI1 is the CSI for slot 1, then CSI0 and CSI1 may have different amounts of beam information. The time slot corresponding to the CSI may be a time slot for measuring the CSI, or a time slot in which a CSI reference resource of the CSI is located.

In this embodiment, the beam information includes at least one of the following: beam vector, bandwidth amplitude information, subband amplitude information, phase information.

Wherein the beam vector can be expressed as

m1 and m2 correspond to the two horizontal and vertical dimensions of the beam, respectively, and i can represent the identification or number of the beam; the wideband amplitude information may be expressed as

Amplitude coefficients over the entire bandwidth corresponding to layer i and beam i; the subband amplitude information may be expressed as

Amplitude coefficients on each subband corresponding to layer l and beam i; the phase information can be expressed as

And

and

corresponding to the phases in the two polarization directions, respectively, to layer i and beam i.

The reporting of the CSI according to the determined number of the beam information includes:

and determining the beam information in a preset codebook based on the preset codebook according to the number of the determined beam information, and reporting the beam information.

The preset codebook can be a type II codebook; correspondingly, according to the number L of the determined beam information, the beam information in the codebook is determined based on the type II codebook, and the beam information is reported. For example, beam vectors, broadband amplitude information and phase information corresponding to L beams in the plurality of beams are determined, and the beam information is reported.

With respect to the aforementioned type II codebook, the highest two-layer transmission can be supported, wherein the codebooks for layers (Rank)1 and Rank2 are as follows:

in the case of Rank1, the Rank,

in the case of Rank2, the Rank,

wherein the content of the first and second substances,

in the above-mentioned formula, the first and second,

is a normalization coefficient;

the value of the number L of beam information is the same as the number of beam information in the embodiment;

the corresponding beam i is a two-dimensional DFT beam vector, and m1 and m2 respectively correspond to two horizontal and vertical dimensions of the beam; 1, 2 respectively corresponds to codebook vectors of two layers;

the codebook vector for each layer consists of two parts:

and

codebook vectors corresponding to two polarization directions respectively;

and

amplitude coefficients corresponding to the wideband and subband, respectively, corresponding to layer 1 and beam i;

and

corresponding to the phases in the two polarization directions, respectively, corresponding to layer 1 and beam i; the number of phases available may be 4 for Quadrature Phase Shift Keying (QPSK), or 8 for 8 Phase Shift Keying (PSK).

It should be noted that, when the CSI including the beam information corresponding to the multiple beams is reported in this embodiment, the specific information types included in the beam information reported by each beam are the same, for example, the beam vector, the bandwidth amplitude, and the phase information are all reported; or setting to report the beam vector, the broadband amplitude information, the sub-band amplitude information and the phase information. Specifically, the type of the reported information may be configured by the network side according to the actual situation, and is not exhaustive in this embodiment.

The CSI here includes at least one of CRI, RI, PMI, and CQI.

By adopting the scheme, the number of the beam information contained in the CSI report of the terminal equipment can be determined according to the preset condition; therefore, when the terminal equipment reports the CSI, the number of the beam information contained in the CSI can be flexibly adjusted, and the problems that the CSI is reported according to the number of the beam information configured by the high-level signaling of the network side all the time, the cost of the feedback signaling is overlarge, and a large amount of uplink resources are occupied can be solved.

Example II,

An embodiment of the present invention provides a CSI reporting method, which is applied to a network device, and as shown in fig. 3, the method includes:

step 301: determining the number of beam information contained in CSI report of the terminal equipment;

step 302: and receiving the CSI report of the terminal equipment according to the determined quantity of the beam information.

In the processing of the present embodiment, the following two methods may be included: after the network side determines the number of beam information reported by the CSI of the terminal equipment, the network side indicates the number of the beam information to the terminal equipment by triggering the DCI reported by the CSI of the terminal equipment; and the network side determines the number of beam information contained in the CSI report according to the transmission parameters reported by the terminal equipment CSI or the physical resources corresponding to the CSI report, and waits for receiving the CSI report of the terminal equipment based on the determined number. Specifically, the method comprises the following steps:

the method 1,

After determining the number of beam information included in the CSI report of the terminal device, the method further includes:

and indicating the number of beam information contained in the CSI report to the terminal equipment by triggering the DCI reported by the CSI.

The indication of the number of beam information contained in the CSI report to the terminal device is used to enable the terminal device to perform CSI report according to the number of beam information.

The indicating, to the terminal device, the number of beam information included in the CSI report by triggering the DCI for the CSI report includes one of:

indicating the number of beam information contained in the CSI report by the terminal equipment through a Radio Network Temporary Identifier (RNTI) adopted for carrying out CRC scrambling on the DCI;

indicating the number of beam information contained in the CSI report by the terminal equipment through the DCI format of the DCI;

indicating the number of beam information contained in the CSI report by the terminal equipment through indication information contained in the DCI;

and indicating the number of beam information contained in the CSI report by the terminal equipment through the DCI triggering the CSI report and the number of beam information configured through high-level signaling.

The DCI may be configured to trigger a periodic CSI report or a persistent CSI report; the aperiodic report is to trigger the terminal to carry out single CSI report through DCI; the persistent CSI reporting may be quasi-persistent reporting, where the quasi-persistent reporting is triggering the terminal to perform periodic CSI reporting through DCI or Media Access Control (MAC) signaling until receiving a deactivation signaling.

Specifically, the number of beam information included in the CSI report performed by the terminal device is indicated by the RNTI used for CRC scrambling of the DCI.

For example, the terminal device may determine, based on the first RNTI or the second RNTI used for CRC scrambling in the DCI, the number of beam information included in the CSI report; the first RNTI and the second RNTI correspond to different amounts of beam information. The first RNTI and the second RNTI may be SP-CSI RNTI and Cell Radio Network Temporary Identifier (C-RNTI), respectively.

The DCI format of the DCI indicates the number of beam information included in the CSI report performed by the terminal device, for example, the number of beam information may be different between CSI report triggered by DCI format 0_0 and CSI report triggered by DCI format 0_ 1.

And the number of beam information contained in the CSI report of the terminal equipment is indicated through the indication information contained in the DCI. The indication information included in the DCI is information content included in an information field of the DCI, for example, a certain field may be preset to be used for reporting the number of beam information included in the DCI.

Or, the terminal device may also determine the number of beam information according to other information fields in the DCI. For example, the CSI request information field in the DCI is used to indicate a currently used CSI reporting configuration from a plurality of CSI reporting configurations, and each CSI reporting configuration may include the number of beam information. And obtaining the reporting configuration of the target CSI through the information domain, and simultaneously obtaining the quantity of beam information.

And the number of the beam information contained in the CSI report of the terminal equipment is indicated by the DCI triggering the CSI report and the number of the beam information configured by the high-level signaling. Accordingly, the method can be used for solving the problems that,

two seed scenarios can be involved: a beam of maximum beam information

Sub-scenario 1,

Correspondingly, the terminal equipment selects a value from the number of at least one beam message configured by the high-level signaling based on the DCI, and the selected value is used as the number of the beam messages contained in the CSI report.

Sub-scenario 2,

The number of the at least one beam information configured by the higher layer signaling is only the number of one maximum beam information.

The terminal device may select the number of beam information included in the CSI report from 1 to the number of the maximum beam information based on the number of the maximum beam information and the DCI.

Mode 2,

The determining the number of beam information included in the CSI report of the terminal device includes:

determining the number of beam information contained in the CSI report according to the transmission parameters of the CSI report of the terminal equipment or the physical resources corresponding to the CSI report.

In this way, after the network side determines the number of beam information included in the CSI report performed by the terminal device, the CSI report of the terminal device is received according to the determined number.

The determining, according to a transmission parameter of CSI report of a terminal device or a physical resource corresponding to the CSI report, a number of beam information included in the CSI report includes one of:
