Abstract: A wireless device receives a radio resource control (RRC) message comprising configuration parameters for uplink resources associated with a small data transmission (SDT) procedure of the wireless device. The wireless device transmits, to a base station central unit (BS-CU) via the uplink resources of a base station distributed unit (BS-DU), an RRC resume request message for the SDT procedure, and uplink data associated with the SDT procedure. The wireless device receives, from the BS-CU to via the BS-DU, an RRC release message after the BS-CU receives a message indicating inactivity notification and completion of the SDT procedure.

Abstract: A wireless device receives parameters, including a first discontinuous reception (DRX) configuration associated with unicast transmissions in a cell and a second DRX configuration associated with multicast and broadcast services (MBS) in the cell. The wireless device may also receive a power saving (PS) indication indicating not to start a DRX on duration timer. The PS indication may be applied for the first DRX configuration; and it may not be applied for the second DRX configuration. The wireless device may further skip monitoring, in a first DRX on duration of the first DRX configuration, first physical downlink control channels (PDCCHs) for the unicast transmissions based on receiving the PS indication. The wireless device may also monitor, in a second DRX on duration of the second DRX configuration and while skipping monitoring the first PDCCHs in the first DRX on duration, second PDCCHs for the MBS.

Abstract: A method may include receiving, by a wireless device via a physical downlink shared channel (PDSCH), first downlink signals based on a first reference signal (RS) associated with a preamble for a random-access procedure. The method may also include receiving, by the wireless device, downlink control information (DCI) indicating a transmission configuration indicator (TCI) state applicable to downlink channel receptions. The method may further include, in response to application of the TCI state to the downlink channel receptions, the wireless device receiving second downlink signals via the PDSCH based on the TCI state.

Abstract: A base station transmits, to a wireless device, first reference signals, of a bandwidth part of a cell in a non-power-saving state, from which a first radio link quality is monitored by the wireless device to detect a first synchronization status for the cell. A downlink control information is transmitted that indicates the cell transitioning from the non-power-saving state to a power saving state. Based on the downlink control information, the base station transmits second reference signals, of the bandwidth part of the cell in the power saving state, from which a second radio link quality is monitored by the wireless device to detect a second synchronization status for the cell.

Abstract: A wireless device receives radio resource control message(s) comprising configuration parameters of a cell. The configuration parameters comprise a first configuration of a first sounding reference signal of the cell in a first power state, and a second configuration of a second sounding reference signal of the cell in a second power state. A first command indicating transition of the cell into the first power state is received. In response to the first command, the first sounding reference signal is transmitted via the cell. A second command indicating transition of the cell into the second power state is received. In response to the second command, the second sounding reference signal is transmitting via the cell.

Abstract: Wireless communications may use one or more devices for transmission and/or reception that may lead to potentially harmful exposure. One or more safety measures may be used for wireless communication devices, such as maximum power exposure (MPE) reporting and/or related operations. An MPE report may use a power headroom report (PHR) to include an uplink transmission power reduction value associated with an MPE threshold.

Abstract: A wireless device may receive a first radio resource control (RRC) reconfiguration message triggering a first active bandwidth part (BWP) switching to a first BWP of a first cell. The wireless device may receive a second RRC reconfiguration message triggering a second active BWP switching to a second BWP of a second cell. The second active BWP switching may at least partially overlap in time with the first active BWP switching. Based on the overlapping, the wireless device may communicate using the second BWP in a first slot after a time duration. The time duration may be determined based on a duration of the first active BWP switching.
