Abstract:
Techniques discussed herein can facilitate determination of spatial (and/or beam) assumption(s) for PDSCH (Physical Downlink Shared Channel) transmitted after a BFR (Beam Failure Recovery) request but before TCI (Transmission Configuration Information) reconfiguration. One example embodiment can be an apparatus configured to: generate a BFR request that indicates a new candidate beam; process a CORESET (Control Resource Set)-BFR of a set of configured CORESETs, wherein the CORESET-BFR comprises a response to the BFR request; determine a spatial assumption for a first PDSCH based on the BFR request, wherein the first PDSCH is scheduled by a first CORESET of the set of configured CORESETs, wherein the first CORESET is different than the CORESET-BFR, wherein the first PDSCH is scheduled before a TCI state is one of reconfigured, reactivated, or re-indicated; and process the first PDSCH based on the determined spatial assumption for the first PDSCH.
