AI Technical Summary

Technical Problem

Existing sidelink communication methods in wireless communication networks face challenges with high signaling load and latency in radio resource allocation, particularly in subnetworks that require autonomy from the parent network.

Method used

The implementation of specific message exchanges using existing control channels for sidelink communication, including downlink and uplink control information, scheduling requests, and user device support information, to enhance radio resource allocation efficiency and reduce signaling complexity and latency within subnetworks.

Benefits of technology

This approach reduces signaling load and latency in sidelink communication by optimizing resource allocation processes within subnetworks, ensuring efficient and timely communication even in the absence of direct connection to the parent network.

Abstract

Devices and methods for allocating radio resources for sidelink communication in a subnet (106) of the wireless communication network (100), the method comprising: - Receiving a message (3) containing information about the radio resources allocated to the subnetwork (106) and an indication that the radio resource allocation is intended for the subnetwork (106), - Detecting the clue, allocating radio resources to at least one user device (104) in the subnetwork (106), and - Sending a message (4) that includes the radio resources allocated to the at least one user device (104).
