摘要:
A wireless device may receive one or more radio resource control (RRC) messages. The RRC messages may indicate a first transmission and reception point (TRP) of a cell, a second TRP of the cell, and one or more first beam failure recovery parameters indicating one or more first reference signals for first TRP. The wireless device may determine a first beam failure of the first TRP based on the one or more first reference signals indicated by the one or more first beam failure recovery parameters. The wireless device may transmit an uplink signal via the second TRP of the cell indicating a link recovery request for the first TRP. The wireless device may receive an uplink grant for uplink data. The wireless device may transmit the uplink data indicating a candidate beam of the first TRP.
