Abstract: A wireless device receives one or more messages comprising one or more configuration parameters indicating a single frequency network (SFN) scheme for a control channel. The wireless device receives a medium access control control element (MAC CE) indicating activation of a set of two transmission configuration indicator (TCI) states for a control resource set (coreset) for the SFN scheme. Based on a downlink signal overlapping in at least one symbol with the coreset activated with the two TCI states, the wireless device receives the downlink signal using a first TCI state among the two TCI states. The first TCI state is selected based on an identifier of the first TCI state occurring first, in the MAC CE, among the identifiers of the two TCI states.

The uplink data is received based on a listen-before-talk procedure indicating a clear channel before the starting position. The uplink data is mapped to resource elements corresponding to the resource blocks based at least on the starting position and the ending symbol.

The wireless device starts the RAR window from a starting time based on the preamble transmission occasion, the first time offset, and a second time offset. The wireless device receives, during the RAR window, an RAR of the preamble transmission.
