Abstract: Wireless communications are described for controlling a transmission. A base station may cancel, delay, and/or request a retransmission of a message. 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.

The second access node receives, from the first access node, a message requesting a handover of a wireless device to the first cell.

Abstract: A wireless device receives one or more configuration parameters indicating a physical uplink shared channel (PUSCH) resource for transmission of a message A (MsgA) payload of a contention-free two-step random-access procedure. The wireless device receives, from a radio resource control (RRC) layer of the wireless device, a request to reset a medium access control (MAC) layer of the wireless device. In response to the request and based on the configuration parameter indicating the PUSCH resource, the PUSCH resource for the MsgA transmission of the contention-free two-step random-access procedure is cleared.

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.

Abstract: A method includes transmitting, by a wireless device and via a serving cell with a first physical cell index (PCI), a first power headroom report (PHR) of the serving cell and a second PHR of a non-serving cell with a second PCI. The first PHR of the serving cell is determined based on a first pathloss reference signal. The second PHR of the non-serving cell with the second PCI is different from the first PCI of the serving cell. The second PHR of the non-serving cell with the second PCI is determined based on a second pathloss reference signal.

Abstract: A wireless device receives a radio resource control message comprising a first sounding reference signal (SRS) resource set identifier of a first SRS resource set of a serving cell and a second SRS resource set identifier of a second SRS resource set of the serving cell. The wireless device transmits a power headroom report (PHR) medium access control control element (MAC CE) comprising a first field indicating a first power headroom value associated with the first SRS resource set and a second field indicating a second power headroom value associated with the second SRS resource set. The order of the first field and the second field in the PHR MAC CE is based on an ascending order of the first SRS resource set identifier and the second SRS resource set identifier.

Abstract: A wireless device selects a first resource for transmission of a sidelink data. The wireless device triggers, in response to determining a channel occupancy time (COT) duration, resource selection for the transmission.
