Method, device and computer readable medium for uplink control information transmission
Embodiments of the present disclosure relate to methods, devices and computer readable media for Uplink Control Information (UCI) transmission. In example embodiments, a method for communication includes determining, at a terminal device, a first part of a first codebook and a second part of a second codebook, the first part and the second part indicating presence or absence of gains for a plurality of pairs of spatial domain (SD) basis and frequency domain (FD) basis, the first codebook and the second codebook being used for different transmission layers between the terminal device and a network device; determining a bit sequence based on the first part and the second part, each bit in the bit sequence corresponding to one of the plurality of pairs of SD basis and FD basis; and transmitting, to the network device, uplink control information including the bit sequence.
1. A method performed by a terminal device, the method comprising:
determining a Channel State Information (CSI) report based on a codebook with a first number of frequency domain (FD) basis vectors; and
transmitting the CSI report on physical uplink shared channel (PUSCH),
wherein the CSI report omits a portion of CSI based on indices of the FD basis vectors, and the CSI report indicates a starting point and the starting point is limited to a configured range,
wherein a coefficient amplitude associated with the indices of the FD basis vectors is restricted to be smaller than a configured maximum amplitude.
2. The method of claim 1 , wherein the portion of CSI is omitted based on order of the indices of the FD basis vectors.
3. A terminal device comprising:
a processor configured to cause the terminal device to:
determine a Channel State Information (CSI) report based on a codebook with a first number of frequency domain (FD) basis vectors; and
transmit the CSI report on physical uplink shared channel (PUSCH),
wherein the CSI report omits a portion of CSI based on indices of the FD basis vectors, and the CSI report indicates a starting point and the starting point is limited to a configured range,
wherein a coefficient amplitude associated with the indices of the FD basis vectors is restricted to be smaller than a configured maximum amplitude.
4. The terminal device of claim 3 , wherein the portion of CSI is omitted based on order of the indices of the FD basis vectors.
