Abstract:
User equipment (UE) operation in a single frequency network (SFN). The UE may receive one or more transmission configuration indication (TCI) states corresponding to one or more downlink resources, receive a demodulated reference signal (DMRS) wherein the DMRS is quasi co-located (QCLed) with one or more channel state information reference signal (CSI-RS) from multiple cells of a SFN and quasi co-location (QCL) information is included in the one or more TCI and determine a time and frequency offset corresponding to each of the multiple cells based on the CSI-RS.
