CPC H04W 72/21 (2023.01) [H04B 7/0626 (2013.01)] | 18 Claims |
1. A method for wireless communication, comprising:
receiving, by a terminal device, one or more reference signals from a base station;
determining, by the terminal device, channel state information by measuring the one or more reference signals;
generating, by the terminal device, a first bit sequence of uplink control information based on a first partial field of the channel state information, the first partial field carrying an indicator indicating a number of coefficients in a first matrix, wherein the first matrix is determined based on L vectors and M vectors; and
generating, by the terminal device, a second bit sequence of the uplink control information based on a second partial field of the channel state information, the second partial field carrying information that comprises (1) information indicating a bitmap that identifies positions of the coefficients in the first matrix, (2) information identifying a strongest coefficient in the first matrix, and (3) information indicating an amplitude and a phase of the coefficients in the first matrix,
wherein a first field of the second bit sequence that corresponds to the information identifying the strongest coefficient in the first matrix is positioned immediately before a second field of the second bit sequence that corresponds to the information indicating the amplitude and the phase of the coefficients, wherein, in the second field, information of the amplitude of the coefficients is followed by information of the phase of the coefficients; and
transmitting the uplink control information comprising the first bit sequence and the second bit sequence to the base station.
