AI Technical Summary

Technical Problem

The existing wireless communication systems have problems inefficient in determining feedback timing capabilities and resource authorization. Especially in 5G communication technology, the feedback forwarding timing capabilities between user equipment (UE) and base stations are difficult to accurately determine, resulting in resources. Improper allocation will affect the quality of communication.

Method used

Receive and process feedback timing from the receiver UE in side link communication through user equipment (UE) to determine the feedback forwarding timing capability and generate uplink resource authorization based on this capability to ensure effective resource allocation and communication scheduling .

Benefits of technology

It improves the efficiency of the determination of feedback timing capabilities and resource authorization in wireless communication systems, optimizes resource allocation, and improves communication quality and performance, especially in 5G technology to support a variety of usage scenarios and applications.

Abstract

Some aspects described herein relate to determining, by a transmitter UE in sidelink communication with a receiver user equipment (UE), a feedback forwarding timing capability based at least in part on a first timing for receiving and processing feedback from the receiver UE, and receiving at least an uplink resource grant from an access point for sending feedback for at least one of the sidelink communication or the downlink communication based on the feedback forwarding timing capability. Other aspects relate to determining, by a transmitter UE in sidelink communication with a receiver UE, a timing capability for the receiver UE to perform at least one of the following: receiving the sidelink communication from the transmitter UE, or reporting feedback for the sidelink communication to the transmitter UE.
