TECHNIQUES FOR FULL-DUPLEX OPERATION ON SIDELINK AND DOWNLINK IN WIRELESS COMMUNICATIONS SYSTEMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240107603 titled 'TECHNIQUES FOR FULL-DUPLEX OPERATION ON SIDELINK AND DOWNLINK IN WIRELESS COMMUNICATIONS SYSTEMS

Simplified Explanation

The patent application describes methods, systems, and devices for wireless communications that allow a first user equipment (UE) to establish a communication link with a base station and a sidelink communication link with a second UE using different transmission reception points associated with the first UE. The first UE can perform interference measurements between downlink communications received on the communication link and sidelink communications transmitted on the sidelink communication link. Based on these measurements, the first UE can determine if it can perform full-duplex operations on both links and transmit an indication of its capability to the base station. Additionally, the second UE can perform measurements of interference from downlink signals on the sidelink communication link to inform the decision to use full-duplex communications at the first UE.

• First UE establishes communication link with base station and sidelink communication link with second UE using different transmission reception points.
• First UE performs interference measurements between downlink and sidelink communications to determine full-duplex capability.
• Second UE performs interference measurements on sidelink communication link to inform decision on full-duplex communications.

Original Abstract Submitted

methods, systems, and devices for wireless communications are described. generally, the described techniques provide for a first user equipment (ue) to establish a communication link with a base station and a sidelink communication link with a second ue using different transmission reception points associated with the first ue. the first ue may perform an interference measurement between downlink communications received on the communication link and sidelink communications transmitted on the sidelink communication link. the first ue may determine whether it is able to perform full-duplex operations on the communication link and the sidelink communication link based on the interference measurement and may transmit an indication of the capability of the first ue to the base station. in some examples, the second ue may perform measurements of interference from downlink signals on the sidelink communication link, where the measurements may inform the determination to use full-duplex communications at the first ue.
