Abstract: A cell transmits synchronization signal blocks (SSB) to a user equipment (UE) for the UE to synchronize with the cell. The cell configures a discovery reference signal (DRS) window for synchronization signal block (SSB) transmission to a user equipment (UE), determines that a channel in an unlicensed spectrum is not occupied and transmits multiple SSBs to the UE in response to determining that the channel in the unlicensed spectrum is not occupied.

Abstract: A user equipment (UE) is connected to a wireless network and operates in a carrier aggregation (CA) state that includes a first connection to a primary cell and a second connection to a secondary cell. The UE determines a beam failure has occurred for one of the first connection or the second connection and initiates a beam failure recovery (BFR) operation. The BFR operation includes transmitting, to the primary cell, a BFR Medium Access Control (MAC) Control Element (CE).
