Wang discloses determining a channel matrix based on measurements from a received reference signal but fails to explicitly recite the use of an antenna receiving the reference signal and therefore fails to disclose “deriving, by the processor, a channel response information observed by a receiving domain of the apparatus according to the reference signal;”. In a related field of endeavor, Li discloses: deriving, by the processor, a channel response information observed by a receiving domain of the apparatus according to the reference signal; (Li, [0318] discloses the generated first indication information is specific to each receive port, that is, channel information of the receive port is fed back.

For example, if the first indication information indicates two precoding submatrices; Li, [0245] discloses The precoding matrix indicator may indicate a precoding matrix or directly indicate a channel matrix. The precoding matrix may be, for example, a precoding matrix determined by the terminal device based on a channel matrix of each subband. The channel matrix may be determined by the terminal device through channel estimation; Li, [0290]-[0291] discloses reference signal, RS and precoded reference signal: The reference signal may also be referred to as a pilot, a reference sequence, or the like. In embodiments of this application, the reference signal may be a reference signal for channel measurement. For example, the reference signal may be a channel state information reference signal CSI-RS and discloses The precoded reference signal may be a reference signal obtained by precoding a reference signal. In embodiments of this application, the precoding may specifically include beamforming and/or phase rotation.

In this case, the first apparatus feeds back ports, frequency domain basis vectors, and angle-delay pair coefficients that can be used to determine a plurality of precoding submatrices; Li, [0265] discloses The port is a short name of an antenna port, and may be understood as a transmit antenna that can be identified by the receiving device or as a transmit antenna that can be spatially distinguished. One antenna port may be configured for each virtual antenna, each virtual antenna may be a weighted combination of a plurality of physical antennas, and each antenna port may correspond to one reference signal. Therefore, each antenna port may be referred to as a reference signal port, for example, a channel state information reference signal CSI-RS port or a sounding reference signal SRS port; Li, [0244] discloses Precoding technology: When a channel state is known, the network device may process a to-be-sent signal by using a precoding matrix that matches a channel resource, so that a precoded to-be-sent signal adapts to a channel, to reduce complexity of eliminating inter-channel impact by a receiving device. Therefore, after the to-be-sent signal is precoded, received signal quality for example, a signal to interference plus noise ratio signal to interference plus noise ratio, SINR is improved. Therefore, by using the precoding technology, a sending device and a plurality of receiving devices may perform transmission on a same time- frequency resource; Li, [0273] discloses a process in which the network device performs the spatial domain precoding on the reference signal is implemented inside the device; Li, [0281] discloses to distinguish different delays, the network may precode a reference signal based on each of L delay vectors; Li, [0479] discloses when the fifth indication information is determined based on the received precoded reference signals of the port groups, and the port groups include the plurality of port groups for example, three or more port groups, where the quantity may be a quantity of TRPs in a coordinating set, the fifth indication information includes information about the selected ports, frequency domain basis vectors, and angle-delay pair coefficients that are used to determine the plurality of precoding submatrices; Li, [0041] discloses Based on the foregoing solution, the first indication information jointly indicates basis vectors and linear combination coefficients that correspond to different port groups, so that signaling overheads for feeding back channel state information can be reduced. In addition, the different port groups may correspond to different quantities of basis vectors including spatial domain basis vectors and frequency domain basis vectors and different quantities of linear combination coefficients. Such non-uniform overhead allocation manner can improve overall feedback precision of the precoding matrix.

After determining the feedback mode based on the preset rule, the network device (i.e. reads on to the network side) may restore a precoding matrix based on the feedback mode and the PMI; Wang, [0156] discloses The terminal device may determine the PMI based on the ideal precoding matrix of each subband. In this embodiment of this application, the precoding matrix of each subband may be determined based on R groups of space-frequency information corresponding to R transmission layers. Each group of space-frequency information in the R groups of space-frequency information (i.e. reads on and the preferred domain) may include space domain information, frequency domain information, and a coefficient (i.e. reads on based on the linear combination coefficient representation); Wang, [0360] discloses Because different change rules in frequency domain are described by using a plurality of frequency domain basis vectors, a relationship between the subbands is fully used, and change rules on all subbands may be described by using a relatively small quantity of frequency domain basis vectors according to frequency domain continuity, to compress feedback overheads. Compared with a conventional technology manner of per-subband feedbacks, feedback overheads caused by subband feedbacks can be greatly reduced, and approximation precision by using the type II codebook can also be ensured; Wang, [0240] discloses The terminal device may determine the PMI based on the foregoing determined space-frequency matrix, or may determine the PMI based on the P×L space domain column vectors at the r.sup.th transmission layer that are determined in operation ii, the K frequency domain basis vectors at the r.sup.th transmission layer that are determined in operation iv, and the P×L×K weighting coefficients that are determined in operation v; Wang, [0365] discloses It should be noted that the precoding matrix indication method provided above is particularly applicable to a case in which there are a large quantity of subbands and the subbands are continuous. In this method, a correlation between the subbands can be fully used, and feedback overheads can be compressed, thereby reducing huge overheads caused by a plurality of subband feedbacks). Wang discloses determining a channel matrix based on measurements from a received reference signal but fails to explicitly recite the use of an antenna receiving the reference signal and therefore fails to disclose “deriving a channel response information observed by a receiving domain of the apparatus according to the reference signal;”. In a related field of endeavor, Li discloses: deriving a channel response information observed by a receiving domain of the apparatus according to the reference signal; (Li, [0318] discloses the generated first indication information is specific to each receive port, that is, channel information of the receive port is fed back. The first apparatus (i.e. rads on of the apparatus) receives reference signals (i.e. reads on according to the reference signal) sent by at least two TRPs where one TRP corresponds to one port group, and sorts and rearranges information about channels used by the at least two TRPs to send the reference signals, to generate the first indication information (i.e. reads on deriving a channel response information observed) specific to each receive port (i.e. reads on by a receiving domain). For example, if the first indication information indicates two precoding submatrices; Li, [0245] discloses The precoding matrix indicator may indicate a precoding matrix or directly indicate a channel matrix. The precoding matrix may be, for example, a precoding matrix determined by the terminal device based on a channel matrix of each subband. The channel matrix may be determined by the terminal device through channel estimation; Li, [0290]-[0291] discloses reference signal, RS and precoded reference signal: The reference signal may also be referred to as a pilot, a reference sequence, or the like. In embodiments of this application, the reference signal may be a reference signal for channel measurement. For example, the reference signal may be a channel state information reference signal CSI-RS and discloses The precoded reference signal may be a reference signal obtained by precoding a reference signal. In embodiments of this application, the precoding may specifically include beamforming and/or phase rotation. The beamforming may be implemented, for example, by precoding a reference signal based on one or more angle vectors. The phase rotation may be implemented, for example, by precoding a reference signal based on one or more delay vectors; Li, [0459] discloses The first apparatus may receive the precoded reference signals of the plurality of for example, three or more, where the quantity may be a quantity of stations for joint transmission port groups. In this case, the first apparatus feeds back ports, frequency domain basis vectors, and angle-delay pair coefficients that can be used to determine a plurality of precoding submatrices; Li, [0265] discloses The port is a short name of an antenna port, and may be understood as a transmit antenna that can be identified by the receiving device or as a transmit antenna that can be spatially distinguished. One antenna port may be configured for each virtual antenna, each virtual antenna may be a weighted combination of a plurality of physical antennas, and each antenna port may correspond to one reference signal. Therefore, each antenna port may be referred to as a reference signal port, for example, a channel state information reference signal CSI-RS port or a sounding reference signal SRS port; Li, [0244] discloses Precoding technology: When a channel state is known, the network device may process a to-be-sent signal by using a precoding matrix that matches a channel resource, so that a precoded to-be-sent signal adapts to a channel, to reduce complexity of eliminating inter-channel impact by a receiving device. Therefore, after the to-be-sent signal is precoded, received signal quality for example, a signal to interference plus noise ratio signal to interference plus noise ratio, SINR is improved. Therefore, by using the precoding technology, a sending device and a plurality of receiving devices may perform transmission on a same time-frequency resource; Li, [0273] discloses a process in which the network device performs the spatial domain precoding on the reference signal is implemented inside the device; Li, [0281] discloses to distinguish different delays, the network may precode a reference signal based on each of L delay vectors; Li, [0479] discloses when the fifth indication information is determined based on the received precoded reference signals of the port groups, and the port groups include the plurality of port groups for example, three or more port groups, where the quantity may be a quantity of TRPs in a coordinating set, the fifth indication information includes information about the selected ports, frequency domain basis vectors, and angle-delay pair coefficients that are used to determine the plurality of precoding submatrices; Li, [0041] discloses Based on the foregoing solution, the first indication information jointly indicates basis vectors and linear combination coefficients that correspond to different port groups, so that signaling overheads for feeding back channel state information can be reduced. In addition, the different port groups may correspond to different quantities of basis vectors including spatial domain basis vectors and frequency domain basis vectors and different quantities of linear combination coefficients. Such non-uniform overhead allocation manner can improve overall feedback precision of the precoding matrix.
