Apparatus and methods for a multi-panel UE to convey a blackout period

Abstract:

There may be a gap between the time a beam pair link (BPL) impacted by a beam failure (BF) event is deactivated and the time a replacement BPL is activated and becomes fully functional at a UE. The gap may be called a blackout period. A base station may not know the blackout period and may continue transmitting to the UE on the impacted BPL during the blackout period. This may result in a transmission failure. Disclosed herein are apparatus and methods for determining a blackout period associated with a beam failure (BF) event and communicating a blackout indication to a base station, the blackout indication including the blackout period.
