COORDINATED CHANNEL ACCESS TECHNIQUES FOR SIDELINK COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17824660 titled 'COORDINATED CHANNEL ACCESS TECHNIQUES FOR SIDELINK COMMUNICATIONS

Simplified Explanation

- This patent application describes methods, systems, and devices for wireless communications in sidelink communications. - Sidelink communications refer to direct communication between user equipment (UE) devices without going through a base station. - The innovation focuses on establishing a connection via sidelink and agreeing on transmission directions and a traffic pattern for a sidelink channel. - In this system, a transmitting UE has higher priority in channel access than a receiving UE. - Two or more UEs can agree on a resource pattern for a set of sidelink resources, where a first UE has higher priority than a second UE for a first subset of resources. - The first UE is given higher priority in the first subset of resources through adjustments to channel access procedures, access thresholds, channel access priority classes, contention window adjustments, or combinations thereof. - Layer one signaling is used to reconfigure channel access priority and the traffic pattern between UEs.

Original Abstract Submitted

Methods, systems, and devices for wireless communications are described that provide for user equipment (UE) in sidelink communications to agree on transmission directions and a traffic pattern for a sidelink channel, where a transmitting UE has higher priority in channel access than a receiving UE. When establishing a connection via sidelink, two or more UEs may agree on a resource pattern for a set of sidelink resources where a first UE has higher priority than a second UE for a first subset of resources. The first UE may be given higher priority in the first subset of resources through adjustments to a channel access procedure for requesting channel access, adjustments to one or more access thresholds or channel access priority classes, contention window adjustments, or any combinations thereof. Layer one signaling may be used to reconfigure channel access priority and the traffic pattern between UEs.
