  • Patent number: 11122612
    Abstract: A wireless device receives RRC message(s) comprising: parameter(s) indicating whether a configured periodic grant of a first type can be used for transmission of data of a first logical channel; a timing offset and a symbol number identifying a resource of an uplink grant of the configured periodic grant of the type; and a first periodicity of the configured periodic grant. The first periodicity indicates a time interval between two subsequent resources of the configured periodic grant. The configured periodic grant is activated in response to receiving the RRC message(s). The data of the logical channel is multiplexed onto transport block(s) for transmission via the resource in response to the parameter(s) indicating that the configured periodic grant can be used by the logical channel. The transport block(s) are transmitted via the resource of the configured periodic grant.

  • Patent number: 11122642
    Abstract: A wireless device transmits one or more preambles in response to initiating a beam failure recovery. The wireless device determines a failure of the beam failure recovery based on a number of transmissions of the one or more preambles exceeding a first number. The wireless device determines a radio link failure in response to the failure of the beam failure recovery. The wireless device starts, based on the radio link failure, a radio resource control (RRC) connection re-establishment procedure with a radio link failure report indicating the failure of the beam failure recovery is a cause of the radio link failure.
