Methods and systems for enhancement of codebook based uplink or physical uplink shared channel transmission

A method for performing a physical uplink shared channel (PUSCH) operation using a plurality of transmitters including at least eight transmitters, comprising:

• determining, by a user equipment (UE) a coherency mode of the PUSCH operation;
• transmitting, from the UE to a network device, a UE capability corresponding to the coherency mode of the PUSCH operation;
• transmitting, from the UE to the network device, an indication corresponding to an antenna architecture of the UE;
• determining an uplink (UL) transmit precoding matrix indicator (TPMI) codebook for the PUSCH operation in accordance with the coherency mode and a UE capability corresponding to the antenna architecture of the UE;
• and
• in accordance with the determining of the UL TPMI codebook, transmitting, from the UE to the network device, an indication corresponding to the determined UL TPMI codebook.

A network device, comprising:

• a transceiver;
• and
• a processor configured to:
• receive, via the transceiver and from a user equipment (UE),
• a UE capability corresponding to a coherency mode of a codebook based physical uplink shared channel (PUSCH) operation using a plurality of transmitters and a single-panel or a multi-panel antenna architecture of the UE;
• and
• an antenna architecture of the UE in accordance with the UE capability corresponding to the coherency mode of a PUSCH operation and the codebook based PUSCH operation;
• and
• in accordance with the UE capability corresponding to the antenna architecture, configure or update, an uplink (UL) transmit precoding matrix indicator (TPMI) codebook for the PUSCH operation using a radio resource control (RRC) signaling.
