Preamble transmission counter for a beam failure recover of a wireless device
Abstract:
A wireless device starts a beam failure recovery (BFR) timer in response to initiating a contention-free random access procedure for a BFR. Based on expiry of the BFR timer, a first preamble employing a contention-based random access for the BFR is transmitted. In response to not receiving a response for the first preamble, a preamble transmission counter is incremented from a value of the preamble transmission counter of the contention-free random access procedure before the expiry of the BFR timer. A second preamble is transmitted in response to a value of the preamble transmission counter being equal to or less than a number.
