Autonomous transmission configuration updating

Abstract:

Methods, systems, and devices for wireless communications are described that allow secondary cell (SCell) beam failure recovery using a primary cell (PCell). A user equipment (UE) may transmit, via the PCell, an indication of a beam failure of the SCell in a scheduling request (SR) or in a dedicated SR message. After receiving the indication, the base station may request a report from the UE or alternatively, may monitor a set of resources for a report without transmitting a request to the UE. The report may be transmitted via the PCell and may include an indication of a selected beam to use for subsequent communications on the SCell. Based on the report, the base station may modify its transmission configuration for the SCell and communicate with the UE via the selected beam.
