AI Technical Summary

Technical Problem

Existing wireless communication methods fail to guarantee compliance with time constraints for round-trip time (RTT) and packet delay budgets (PDB) due to unpredictable radio resource availability, leading to interference and inefficiencies in applications like closed-loop control.

Method used

A method for selecting radio resources that ensures availability for both forward and reverse packet operations within defined time windows, using a first set of resources for forward packets and a second set for associated operations, ensuring sufficient resources are available within a time frame that meets operational constraints.

Benefits of technology

Guarantees compliance with time constraints for wireless communication, enhancing the reliability and efficiency of applications by ensuring timely reception and transmission of packets.

Abstract

The present invention relates to a method including: obtaining a first set of radio resources available for forward packet transmission from a first user equipment; obtaining a second set of radio resources available for performing operations related to forward packets; selecting a first radio resource having a first time from among the first set of radio resources, such that at least one second radio resource from the second set is included within a time window having a lower limit after the first time and an upper limit defined according to at least one of the forward packets; and transmitting the forward packet using the first radio resource by the first user equipment.
