Abstract
Apparatuses and methods for uplink (UL) codebook design are provided. A method performed by a user equipment (UE) is provided. The method includes receiving a configuration about an uplink (UL) codebook (C) for N=8 antenna ports partitioned into Ngroups; receiving an indication indicating a transmit precoding matrix indicator (TPMI) for transmission of a physical uplink shared channel (PUSCH); and transmitting the PUSCH based on the indicated TPMI. The TPMI indicates a precoding matrix (W) from the UL codebook (C) and the precoding matrix (W) is based on up to K submatrices. Each of the K submatrices is a full-coherent (FC) precoding matrix for antenna ports and is associated with one of the Ngroups, K∈{1, . . . , N} and N∈{2, 4}.
