1. Channel Information

In the present application, channel information can be used to characterize channel characteristics or features or channels. For example, the channel information may include at least one of the following: a channel matrix H, an equivalent channel matrix, a precoding matrix W (the precoding matrix W can be derived from the channel matrix H), a right singular vector V of the channel matrix H, an eigenvector of the square matrix H ^T H (the eigenvector of the matrix obtained by multiplying the conjugate transpose ^HT of the channel matrix by the channel matrix H), at least one vector associated with the channel matrix H (such as at least one vector of the channel matrix H under a certain deformation, etc.), time domain information of the channel, channel information in the delay-doppler domain, CSI, etc. In the present application, the terminal device obtains channel information by performing channel measurement on the downlink reference signal. Measurement can also be described as evaluation, detection or estimation, etc. Among them, the downlink reference signal may include but is not limited to a channel state information reference signal (CSI-RS), a synchronization signal and a physical broadcast channel block (SSB) or a physical broadcast channel demodulation reference signal (PBCH DMRS), etc.

In this application, CSI can be used to describe information related to channel quality. For example, CSI describes the propagation process of wireless signals between transmitters and receivers, including the effects of distance, scattering, fading, etc. on the signal. For downlink transmission, CSI can be used by terminal devices to feedback downlink channel quality to network devices so that network devices can perform resource scheduling, beam management, mobility management, etc. based on CSI. The CSI sent by the terminal device to the network device can be carried in the CSI report. For example, the CSI can be the CSI in the LTE or 5G NR system. It can also be the CSI including the type 1 codebook or the CSI of the type 2 codebook in the 5G NR system, or it can be periodic CSI, semi-continuous CSI, or non-periodic CSI.

The CSI of the Type 1 codebook may be, for example, the CSI of the R15 Type 1 codebook (R15 Type 1 codebook), the CSI of the R16 Type 1 codebook (R16 Type 1 codebook), the CSI of the R17 Type 1 codebook (R16 Type 1 codebook), or the CSI of the Type 1 codebook in a future protocol version.

The CSI of the type 2 codebook may be, for example, the CSI of the R15 type 2 codebook (R15 TypeII codebook), the CSI of the R16 type 2 codebook (R16 TypeII codebook), the CSI of the R17 type 2 codebook (R16 TypeII codebook), or the CSI of the type 2 codebook in a future protocol version, or the CSI of the type 2 codebook may be, for example, the CSI of the R15 enhanced type 2 codebook (R15 enhanced TypeII codebook), the CSI of the R16 enhanced type 2 codebook (R16 enhanced TypeII codebook), the CSI of the R17 enhanced type 2 codebook (R16 enhanced or, the CSI of the Type 2 codebook may be, for example, the CSI of the R15 further enhanced Type 2 codebook, the CSI of the R16 further enhanced Type 2 codebook, the CSI of the R17 further enhanced Type 2 codebook, or the CSI of the further enhanced Type 2 codebook in a future protocol version.

In a possible implementation, the specific process of determining the CSI of the type 1 codebook may be, for example: the terminal device matches the codebook specified by the protocol with the estimated channel, and selects the CSI of the type 1 codebook of the channel that best matches. The CSI of type 2 and its enhanced codebook is generally used for high-precision CSI feedback (also referred to as high-resolution CSI feedback), such as the terminal device processes the estimated channel to obtain the CSI of the high-precision codebook, such as quantization of amplitude and phase.

Exemplarily, the CSI may include at least one of the following: precoding matrix indicator (PMI), channel quality indicator (CQI), channel state information reference signal resource indicator (CSI-RS resource indicator, CRI), layer indicator (LI), synchronization signal block resource indicator index (SS/PBCH block resource indicator, SSBRI), rank indicator (RI), layer indicator (LI), layer 1 reference signal received power (L1-RSRP), layer 1 signal-to-noise and interference ratio (L1-SINR), received angle of arrival (angle of arival, AOA), angle of arrival spread (angle of arival spread, AAS), transmitted angle of departure (angle of departure, AOD), angle of departure spread (angle of departure spread, ADS), spatial correlation (spatial correlation).

2. CSI Report

In the present application, CSI report (CSI-Report) is used to report CSI. For example, CSI report may include at least one of L1-RSRP, L1-SINR, CSI-related information, etc. Among them, CSI-related information may include at least one of the following information: CRI, synchronization signal block resource indicator index (SS/PBCH block resource indicator, SSBRI), RI, PMI, CQI, LI, etc. CSI report can be transmitted through physical uplink control channel (physical uplink control channel, PUCCH) or physical uplink shared channel (physical uplink shared channel, PUSCH).

In a communication scenario, network equipment needs to obtain CSI to overcome some path losses during channel transmission. Generally speaking, network equipment can obtain CSI through CSI reports. However, if AI technology is introduced at the CSI level, there is currently no specific solution for what the CSI report specifically contains. In order to solve this problem, please refer to Figure 2, which is a flow chart of a channel state information report determination method provided in an embodiment of the present application.
