    摘要: A wireless device may receive configuration parameters of an unlicensed cell for uplink transmissions of data of logical channels. Each of the logical channels may be associated with a logical channel priority and a quality of service indicator. The wireless device may receive an uplink grant, for the unlicensed cell, indicating uplink resources and a type of listen-before-talk (LBT). The wireless device may allocate first uplink resources of the uplink resources for first data of a first logical channel, of the logical channels, with a first LBT priority number corresponding to a first quality of service indicator for the first logical channel. The wireless device may allocate remaining uplink resources of the uplink resources for second data of a second logical channel, of the logical channels, with a second LBT priority number lower than the first LBT priority number. The wireless device may perform an LBT procedure based on the type of LBT. The wireless device may transmit the first data and the second data via the uplink resources.

    摘要: A base station transmits, to a wireless device, a first physical downlink control channel (PDCCH) to initiate a random access procedure on an unlicensed cell. The base station, in response to a listen-before-talk (LBT) procedure indicating a clear channel for uplink transmission of a first preamble of the random access procedure, receives the first preamble via a random access channel (RACH) of the unlicensed cell and transmits a second PDCCH for a random access response (RAR). The base station, in response to the LBT procedure indicating an LBT failure, receives a second preamble based on a random access resource selection procedure, and does not transmit the second PDCCH for the RAR.

    摘要: A wireless device not in a radio resource control (RRC) connected state transmits, to a base station that bars a first access category, a first message for a small data transmission (SDT) procedure. The first message comprises an RRC request message and second uplink data associated with a second access category that is not barred. The wireless device not in the RRC connected state receives, from the base station, a second message indicating subsequent transmission associated with the SDT procedure. The wireless device not in the RRC connected state transmits, based on the receiving the second message indicating the subsequent transmission associated with the SDT procedure, a packet associated with the first access category.
