摘要:
Systems, apparatuses, and methods are described for wireless communications. A base station may send, to a wireless device, one or more configuration parameters of a primary cell and a secondary cell. The one or more configuration parameters may comprise: a first preamble for a first beam failure recovery (BFR) procedure of the primary cell, a second preamble for a second BFR procedure of the secondary cell and a time-frequency resource associated with the primary cell. The wireless device may send the first preamble via the time-frequency resource associated with the primary cell to perform the first BFR procedure. The wireless device may send the second preamble via the time-frequency resource associated with the primary cell to perform the second BFR.
