Abstract: A base station may cancel or delay (e.g., pre-empt) a transmission from a wireless device by sending a pre-emption indication to the wireless device. Based on receiving the pre-emption indication, the wireless device may cancel the transmission, store an indication associated with the cancelled transmission, and/or store the cancelled transmission in a data buffer. The base station may request transmission of the data unit (e.g., at a later time) by transmitting another indication.

Abstract: A wireless device and/or a base station may select one or more beams among multiple beams for transmission and/or reception of signals. At least one transmission control indicator (TCI) state of at least two TCI states may be used to receive a downlink signal based on a scheduling offset and the downlink signal overlapping in time with a physical downlink channel transmission.

Abstract: A wireless device comprises one or more processors and memory storing instructions. When executed by the one or more processors, the instructions cause the wireless device to receive, from a base station, a radio resource control (RRC) release message indicating that a signaling radio bearer (SRB) is configured for a small data transmission (SDT) procedure. In response to a signal message associated with the SRB being available, the instructions cause the wireless device to transmit the signal message, while in an RRC idle state or an RRC inactive state, based on a type of the signal message being allowed to use the SDT procedure.

The DCI also comprises a hybrid automatic repeat request (HARQ) process number.

The wireless device transmits a preamble. Based on the wireless device being of the first wireless device type, the wireless device monitors, via the first RA SS on the first initial BWP, a control channel for a response to the preamble. Then the wireless device receives the response on the first initial BWP.

Abstract: A wireless device receives one or more radio resource control messages. The one or more radio resource control messages comprise configuration parameters of semi-persistent channel state information (CSI) reports for transmission via a physical uplink shared channel (PUSCH) of a first cell in a timing advance group. A downlink control information (DCI) indicating activation of semi-persistent CSI is received via PUSCH resources of the PUSCH of the first cell. In response to a time alignment timer of the timing advance group expiring, first PUSCH resources of the PUSCH resources are cleared. The first PUSCH resources occur after the time alignment timer expires.

Abstract: A wireless device initiates a beam failure recovery procedure based on a beam failure of at least one beam of a cell. A radio link failure is determined based on a failure of the beam failure recovery procedure. A radio link failure report is transmitted. The radio link failure report comprises: a first field indicating that the failure of the beam failure recovery procedure is a cause of the radio link failure; and a second field indicating a random access resource for the beam failure recovery procedure.

Abstract: A wireless device receives configuration parameters indicating a linkage between a first search space (SS), of a scheduled cell, and a second SS, of a first bandwidth part (BWP) of a scheduling cell, and that a third SS, of the scheduled cell, is not linked to any SSs of a second BWP of the scheduling cell. In response to the linkage and the first BWP being active, the second SS is monitored for receiving a scheduling indication for the scheduled cell. The wireless device switches from the first BWP to the second BWP as an active BWP of the scheduling cell. In response to the switching and the third SS not being linked to the any SSs of the second BWP, the third SS is monitored for receiving DCI for the scheduled cell. The DCI is received via the third SS and for transmission on the scheduled cell.

Abstract: A wireless device receives indications of: a first scheduling request (SR) resource corresponding to first logical channel(s) having a first logical channel prioritization (LCP) mapping to first radio resources; and a second SR resource corresponding to second logical channel(s) having a second LCP mapping to second radio resources. A buffer status report (BSR) is triggered in response to data becoming available for the second logical channel(s). First uplink grant(s) indicating a first radio resource of the first radio resources is received. An SR for transmission of the BSR is triggered in response to the first radio resource not meeting the second LCP mapping configured for the second logical channel(s) that triggered the BSR. The SR is transmitted via the second SR resource selected based on the second logical channel(s) triggering the BSR. The BSR is transmitted via a second radio resource of the second radio resources.
