Abstract
Apparatuses, methods, and systems are disclosed for determining a TPMI for a codebook set. One method includes receiving information indicating a transmission capability of a remote unit. The method includes determining a transmit precoding matrix indication based on a rank and a codebook corresponding to the transmission capability and the rank, wherein the transmit precoding matrix indication corresponding to a rank of one includes a maximum of five bits, the transmit precoding matrix indication corresponding to a rank of two includes a maximum of four bits, and the transmit precoding matrix indication corresponding to a rank of three includes a maximum of three bits. The method includes transmitting the transmit precoding matrix indication to the remote unit.
