CONGESTION CONTROL FOR POWER SAVINGS IN USER EQUIPMENT FOR DIRECT LINK COMMUNICATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18166810 titled 'CONGESTION CONTROL FOR POWER SAVINGS IN USER EQUIPMENT FOR DIRECT LINK COMMUNICATIONS
Simplified Explanation
The abstract describes a method, apparatus, and computer-readable medium for wireless communication between two user equipment (UE) devices over a sidelink. The first UE device identifies a configuration for discontinuous reception (DRX) for direct link communications with the second UE device. It determines a channel busy ratio (CBR) based on multiple CBR measurement occasions within a specific time window before a direct link transmission. Based on the CBR, the first UE device decides whether to perform congestion control on the direct link transmission. The first UE device then performs the direct link transmission while adhering to a channel occupancy ratio limit.

Original Abstract Submitted
Example implementations include a method, apparatus and computer-readable medium of wireless communication over a sidelink between a first user equipment (UE) and a second UE. The first UE may identify a configuration for discontinuous reception (DRX) for direct link communications with a second UE. The first UE may determine a channel busy ratio (CBR) based on a plurality of CBR measurement occasions within a time window prior to a direct link transmission based on the configuration for DRX. The first UE may determine whether to perform a congestion control on the direct link transmission based on the CBR. The first UE may perform a direct link transmission subject to a channel occupancy ratio limit.
