AI Technical Summary

Technical Problem

It is difficult for existing wireless communication systems to effectively optimize the configuration of random access channels in the positioning-assisted new radio RACH procedures, resulting in low access efficiency and resource utilization of user equipment.

Method used

By using positioning status information (PSI) between user equipment and base stations, optimized RACH procedures dynamically select and configure, including two- or four-step CBRA or CFRA procedures, to accommodate the location and speed information of user equipment.

Benefits of technology

It achieves lower latency, higher throughput and resource savings, and improves the access efficiency of user equipment and the overall performance of the system.

Abstract

Various aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment may transmit to a base station an indication of a selected random access channel (RACH) procedure selected based at least in part on positioning state information (PSI) associated with a UE, wherein the PSI is based at least in part on one or more positioning measurements obtained by the UE; and receive from the base station a resource configuration for the selected RACH procedure. Numerous other aspects are provided.
