CODEBOOK DESIGN FOR 8TX UE WITH FOUR COHERENT ANTENNA GROUPS

Document Type and Number:

WIPO Patent Application WO/2024/074024

Kind Code:

A1

Abstract:

Methods and apparatuses for 8TX UE with four coherent antenna groups are disclosed. In one embodiment, a UE comprises a transceiver; and a processor coupled to the transceiver, wherein the processor is configured to receive, via the transceiver, a control message scheduling a PUSCH transmission with transmission rank N to be transmitted by eight antenna ports in four coherent antenna groups, wherein, the control message includes a TPMI that indicates a 8TX precoding matrix used by the four coherent antenna groups, and wherein, N is any of 1 to 8; and transmit, via the transceiver, the scheduled PUSCH transmission according to the control message.
