Method and apparatus for uplink signal transmission based on codebook in a wireless communication system
A method for transmitting an uplink signal based on a codebook by a UE in a wireless communication system includes: receiving, from a base station, downlink control information (DCI) for determining a precoding matrix applied to transmission of the uplink signal; determining the precoding matrix applied to the transmission of the uplink signal from a codebook subset related to the transmission of the uplink signal based on the DCI; and transmitting, to the base station, the uplink signal based on the determined precoding matrix, I which based on that a difference between phase values applied to antenna ports for the transmission of the uplink signal is maintained in some antenna ports among all antenna port pairs, the codebook subset includes at least one specific precoding matrix applying different phase values to antenna ports included in all or some of the some antenna ports.
1. A method of transmitting a physical uplink shared channel (PUSCH) based on a codebook by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, downlink control information (DCI) for information related to a precoding matrix; and
transmitting, to the base station, the PUSCH based on the precoding matrix determined based on the DCI,
wherein based on that a codebook subset is based on a codebook subset parameter configured to partialAndNonCoherent, the codebook subset includes at least one specific precoding matrix comprising non zero values for all antenna ports,
wherein the at least one specific precoding matrix is related to rank 1 uplink transmission using 4 antenna ports,
wherein the codebook includes a first codebook for a rank 1 using 4 antenna ports,
wherein the first codebook is based on one of the following tables,

wherein the at least one specific precoding matrix is a precoding matrix whose the TPMI index is 12 to 15, among precoding matrices included in the first codebook, and
wherein the codebook subset further includes at least one precoding matrix (i) related to the rank 1 using the 4 antenna ports and (ii) including precoding matrices whose the TPMI index are 0 to 11, among the precoding matrices included in the first codebook.
