摘要:
A base station transmits first random access parameters, associated with beam failure recovery, and second random access parameters. The base station may receive, in response to a beam failure on a primary cell and based on the first random access parameters, a first random access preamble on a first BWP of the primary cell. The base station may receive, based on the second random access parameters and for consistent LBT failure recovery, a second random access preamble on a second BWP of the primary cell. Receiving the second random access preamble may be in response to stopping of a first random access process and switching of an active BWP of the primary cell from the first BWP to a second BWP. The stopping and the switching may be based on consistent LBT failure for the primary cell.
