Abstract: Mechanisms for reduction of channel state information (CSI) feedback overhead are disclosed for full dimensional multiple input, multiple output (FD-MIMO) systems with large dimension antenna ports. In one aspect, rank-dependent CSI antenna port measurements are used in order to limit the number of antenna ports for high rank CSI reporting. Another aspect allows a user equipment (UE) to select subband feedback for aperiodic CSI porting on an uplink shared channel when the UE is to report subband quality and precoding indicators. Another aspect provides for on-demand CSI feedback that dynamically configures CSI feedback parameters. To reduce the signaling overhead, the multiple parameter sets may be pre-configured with different values for dynamic reporting parameters.

Aspects of the disclosure relate to a UE configured to transmit a message to a serving BS, the message including a request for timeline relaxation for transmission of a subsequent message, the message and the subsequent message being associated with a random access procedure. The UE may receive a response message associated with the random access procedure and indicating one or more timing offsets corresponding to the timeline relaxation. The UE may transmit the subsequent message to the serving BS based on the one or more timing offsets indicated by the serving BS. The subsequent message acknowledges the response message.
