Abstract
Aspects of the disclosure relate to a wireless user equipment (UE) establishing and utilizing a reference timing for a carrier or cell with multiple transmission and reception points (TRPs). A UE may receive a downlink signal on each of a plurality of component carriers (CCs), and determine respective timing events (e.g., slot boundaries, subframe boundaries, etc.) corresponding to each of the plurality of CCs. The UE may then determine a reference time for a first CC of the plurality of CCs. This reference time corresponds to a function of two or more timing events corresponding to different TRPs utilizing the first CC. The UE then determines a relative timing difference between the plurality of CCs based on this determined reference time. Other aspects, embodiments, and features are also claimed and described, including determining and utilizing a reference time on an uplink CC.
