Abstract
Techniques discussed herein can facilitate beam failure recovery (BFR) for a Secondary Cell (SCell) or Primary SCell (PSCell). One example embodiment comprises an apparatus configured to be employed in a User Equipment (UE), comprising: one or more processors configured to: generate a Physical Random Access Channel (PRACH) associated with a beam failure recovery request (BFRQ); generate a Physical Uplink Shared Channel (PUSCH) message associated with the BFRQ, wherein the PUSCH message comprises at least one Medium Access Control (MAC) Control Element (CE) that comprises one or more of an index associated with a cell for which beam failure was detected or an index associated with a new beam; and process a Physical Downlink Shared Channel (PDSCH) as a random access response (RAR) associated with the PRACH and the PUSCH message.
