Channel state information reporting for random access procedures

Abstract:

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, from a base station, a downlink transmission in a radio frequency spectrum band and may identify reference resources in the downlink transmission for computing a channel state information (CSI) report. The UE may generate the CSI report based at least in part on the identified reference resources and transmit, in the radio frequency spectrum band, the CSI report in a random access request message to the base station. The base station may receive the request message and identify CSI associated with the band based at least in part on the CSI report included in the random access request message. The base station may transmit, to the UE, a random access response message based at least in part on the identified CSI in the radio frequency spectrum band.
