AI Technical Summary

Technical Problem

In wireless communication systems, how to efficiently manage the Configuration Grant Timer (CGT) during random access to reduce latency and improve resource utilization efficiency, especially in performance-critical applications.

Method used

By receiving the Configuration Grant (CG) configuration associated with the Hybrid Automatic Repeat Request (HARQ) process, sending the Random Access (RA) preamble, receiving the Random Access Response (RAR), and starting the CG timer associated with the HARQ process upon receiving the RAR, the uplink grant management is optimized by sending and retransmitting MSG3 based on the state of the CG timer.

Benefits of technology

Without interrupting UE transmission, uplink licensing for PUSCH transmission and PDCCH scheduling addressed to temporary C-RNTI was implemented, improving the resource utilization efficiency and latency management of the wireless communication system.

Abstract

The present disclosure relates to a method of performing an operation for a user equipment (UE) in a wireless communication system. Specifically, the method comprises the steps of: receiving a configuration authorization (CG) configuration associated with a hybrid automatic repeat request (HARQ) process; transmitting a random access (RA) preamble; receiving a random access response (RAR) including a dynamic uplink grant associated with the HARQ process in response to the RA preamble, where a CG timer associated with the HARQ process is started upon receiving the RAR; in response to the RAR, transmitting the MSG3 on a dynamic uplink grant associated with the HARQ process; and retransmitting the MSG3 on a retransmission uplink grant on the basis that a CG timer related to the HARQ process is running and the retransmission uplink grant associated with the HARQ process is received on a physical downlink control channel (PDCCH) addressed with a temporary cell-radio network temporary identifier (TC-RNTI).
