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: In an aspect, an O-DU transmits a C-Plane message including a section description that specifies common PRB information associated with a plurality of RSs, the section description comprising a set of RS-specific section description extensions that each specify a PRB offset and a modulation scaling factor for a respective RS among the plurality of RSs. The O-RU processes the C-Plane message with modulation compression in accordance with the set of RS-specific section description extensions. In another aspect, a first O-RAN unit (e.g., O-DU or O-RU) transmits a message to a second O-RAN unit (e.g., O-RU or O-DU) associated with combining across symbols at an O-RU.
