Channel state information reporting for random access procedures

A method for wireless communication, comprising:

• receiving, from a user equipment (UE) at a base station, a random access request message of a first step of a shortened random access procedure in a radio frequency spectrum band, the random access request message comprising a channel state information (CSI) report and a request for a grant of resources for communications between the base station and the UE;
• identifying CSI associated with the radio frequency spectrum band based at least in part on the CSI report;
• and
• transmitting, to the UE in accordance with the random access request message, a random access response message of a second step of the shortened random access procedure based at least in part on the identified CSI in the radio frequency spectrum band.

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a base station at a user equipment (UE), a downlink transmission in a radio frequency spectrum band;
• identify reference resources in the downlink transmission for computing a channel state information (CSI) report;
• generate the CSI report based at least in part on the identified reference resources;
• transmit, from the UE to the base station in the radio frequency spectrum band, a random access request message of a first step of a shortened random access procedure, the random access request message comprising the CSI report and a request for a grant of resource for communication between the base station and the UE, and
• receive, in accordance with the random access request message, a random access response message of a second step of the shortened random access procedure, the random access response message based at least in part on the CSI report.

• receive, from a user equipment (UE) at a base station, a random access request message of a first step of a shortened random access procedure in a radio frequency spectrum band, the random access request message comprising a channel state information (CR) report and a request for a grant of resources for communications between the base station and the UE;
• identify CSI associated with the radio frequency spectrum band based at least in part on the CSI report;
• and
• transmit, to the UE in accordance with the random access request message, a random access response message of the shortened random access procedure based at least in part on the identified CSI in the radio frequency spectrum band.
