Title:
SYSTEMS, METHODS, AND APPARATUSES FOR ENABLING MULTIPLE TIMING ADVANCES FOR MULTIPLE TRANSMISSION RECEPTION POINTS IN WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2024/060217
Kind Code:
A8
Abstract:
Systems, methods, and apparatuses for enabling multiple timing advances (TAs) for multiple transmission reception points (TRPs) are disclosed herein. In embodiments, a UE may perform timing advance group (TAG) association for different uplink (UL) transmissions for mTRP use, where a pair of inter-frequency TAGs respectively corresponding to a pair of TRPs is used by the UE for determining TAs for UL transmissions to each TRP. In embodiments, a UE performs downlink (DL) reference timing determinations for two TAs for mTRP use, with such determinations being based on one or more aspects of one or more active transmission configuration indicators (TCI) usable for UL at the UE. In embodiments, a LIE handles cases of overlapped UL transmissions on two respective UL panels due to the use of two TAs corresponding to a pair of TRPs. Network behavior and signaling corresponding to these aspects is also discussed.
