Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive, from a user equipment and at a physical layer entity of the base station, channel state information (CSI) that includes a CSI part 1 and a CSI part 2, the CSI part 1 having a length known to the base station and the CSI part 2 having a length that is based at least in part on a payload of the CSI part 1. The base station may decode, at the physical layer entity of the base station, a payload of the CSI part 2 based at least in part on a payload of the CSI part 1 and one or more parameters indicated by a medium access control (MAC) layer entity of the base station. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A distributed unit (DU) component/function of a base station may determine, for one or more radio units associated with the distributed unit, one or more sampling metrics associated with signal combining operations at the radio units. The DU may select, based at least in part on the one or more sampling metrics, a combining scheme to use for the signal combining operations. The DU may provide an indication of the selected combining scheme to at least one radio unit of the one or more radio units.

Abstract: A distributing unit (DU) signals a maximum IQ data bitwidth for downlink communication associated with a section identifier (ID) to a radio unit (RU). The DU signals a bitwidth parameter to the RU for the downlink communication per a physical resource block (PRB). The DU transmits and the RU receives the downlink communication based on at least one of the maximum IQ data bitwidth or the bitwidth parameter for the PRB. For uplink communications, the DU transmits a first indication of a maximum IQ data bitwidth to the RU in a C-plane message. The RU transmits a second indication of a bitwidth parameter for the uplink communication per a PRB. The RU transmits and the DU receives the uplink communication based on at least one of the maximum IQ data bitwidth or the bitwidth parameter for the PRB.
