AI Technical Summary

Technical Problem

In uplink transmission of extended reality (XR) service data, the allocation of multiple Configured Grants (CGs) leads to waste of radio resources due to varying data volumes, as existing methods fail to accurately determine which CGs are needed for transmission, resulting in inefficient resource utilization.

Method used

A method and apparatus for determining CGs that involve a user equipment (UE) and network-side device to obtain and analyze the data volume of CG clusters, allowing for the identification of CGs that need to be used and those that can be recovered based on the data volume and uplink transmission capacity, thereby optimizing resource allocation.

Benefits of technology

This approach enables accurate and timely recovery of unused CGs, reducing resource waste and enhancing communication efficiency by ensuring only necessary CGs are utilized, thus optimizing resource allocation and improving overall communication performance.

Abstract

This application discloses a method, apparatus, UE, network-side device, and medium for determining a configured grant CG, and belongs to the technical field of communications. The method for determining a configured grant CG according to an embodiment of this application includes: a step in which a user device UE obtains the amount of data to be transmitted by a CG cluster; and a step in which the UE determines at least one of the CGs that need to be used and the CGs that do not need to be used based on the amount of data to be transmitted and the uplink transmission capacity provided by each CG in the above CG cluster.
