Abstract: A first base station distributed unit (BS-DU) receives, from a base station central unit (BS-CU), a first power value for uplink transmission of a wireless device to the first BS-DU. The first BS-DU receives, from the BS-CU, a third power value for uplink transmission of the wireless device to the first BS-DU, wherein the third power value is based on a second power value for uplink transmission of the wireless device to a second BS-DU. The first BS-DU transmits, to the BS-CU, a response confirming addition of the second BS-DU for the wireless device.

Abstract: A method may include sending, by a wireless device to an access and mobility management function (AMF) via a first cell, a first registration request message requesting a network slice. The method may also include receiving, by the wireless device from the AMF, a first registration accept message. The message may include a network slice selection assistance information (NSSAI) indicating the network slice and may also include an indication that the network slice is rejected in a tracking area of a registration area. The method may further include, upon a cell change to a second cell, sending, by the wireless device to the AMF via the second cell and based on the indication, a second registration request message requesting the network slice. The method may additionally include receiving, by the wireless device from the AMF, a second registration accept message accepting the network slice.

Abstract: A wireless device comprising switches to a first downlink bandwidth part (BWP) as an active BWP during a discontinuous reception (DRX) active time. The wireless device, in response to switching to the first downlink BWP, starts a BWP inactivity timer of the first downlink BWP. The wireless device transmits a packet via a transmission interval of periodic resources indicated by a configured grant. The wireless device restarts the BWP inactivity timer at a time based on the transmission interval. The wireless device, in response to an expiration of the BWP inactivity timer, switches to a second downlink BWP as the active BWP during the DRX active time. The wireless device receives a DCI via a physical downlink control channel (PDCCH) of the second downlink BWP.

The wireless device restarts the first inactivity timer for the first BWP of the first cell, in response to communicating a transport block via a configured grant resource of the second cell.

Abstract: A wireless device may be configured to perform a method. The method may include receiving, by the wireless device, configuration parameters indicating duration values for skipping physical downlink control channel (PDCCH) monitoring on a bandwidth part (BWP).

The method may further include receiving a downlink control information (DCI) indicating skipping PDCCH monitoring on the BWP for a time duration based on a duration value of the duration values. The method may additionally include skipping monitoring the PDCCH on the BWP for the time duration based on the DCI.

The base station may send a control message to control a transmission in a communication network. A wireless device may cancel a transmission (e.g., based on a pre-emption indication), determine a transmission power for a transmission (e.g., based on a power control message), and/or determine a retransmission of a message (e.g., based on a repetition indication).

Abstract: A wireless device increments a beam failure instance counter based on a first beam failure instance indication for one or more first reference signals (RSs) for beam failure detection. The wireless device receives a medium access control control element (MAC CE) indicating one or more second RSs for beam failure detection. The wireless device resets the beam failure instance counter in response to receiving the MAC CE. The wireless device increments the beam failure instance counter based on a second beam failure instance indication for the one or more second RSs. The wireless device based on the beam failure instance counter being equal to or greater than a first value, triggers a beam failure recovery for the one or more second RSs.

Abstract: A base station may receive, from a wireless device, uplink data via a first configured grant resource of a first cell of a plurality of cells. The base station may determine a second cell from the plurality of cells to transition from a dormant state to a non-dormant state. The determining may be based on the second cell being configured with a control resource set for receiving uplink grants for retransmission of the uplink data. In response to the receiving, the base station may transition the second cell from the dormant state to the non-dormant state. The base station may transmit, to the wireless device via the second cell, an uplink grant indicating a radio resource. The base station may receive, from the wireless device via the radio resource, a retransmission of the uplink data.
