Abstract: A wireless device receives a layer 1 or layer 2 triggered mobility (LTM) cell switch command. The LTM cell switch command comprises a configuration index indicating a cell for an LTM procedure and does not comprise a timing adjustment value for a primary timing advance group (PTAG) of the cell. In response to receiving the LTM cell switch command with no timing adjustment value, the wireless device starts a time alignment timer associated with the PTAG after measuring a timing advance of the cell.

Abstract: A wireless device receives one or more radio resource configuration (RRC) messages comprising one or more configuration parameters comprising a first configuration parameter and first measurement configuration parameters indicating one or more positioning measurement gaps. In response to the first configuration parameter being enabled, the wireless device determines to trigger a positioning measurement gap activation or deactivation request. Based on the one or more RRC messages comprising the first configuration parameter, the wireless device determines to trigger the positioning measurement gap activation or deactivation request using an uplink medium access control (MAC) control element (CE). The wireless device transmits the uplink MAC CE for activating or deactivating a positioning measurement gap of the one or more positioning measurement gaps.

Abstract: A wireless device receives a radio resource control (RRC) message comprising a configured grant (CG) configuration indicating a plurality of CGs. The CG configuration comprises an unused CG occasion uplink control information (UCI) configuration that comprises a parameter used to determine a size of a bitmap of an unused CG occasion UCI. Based on the CG configuration comprising the unused CG occasion UCI configuration, the wireless device determines that a first CG, of the plurality of CGs, is to be unused for a physical uplink shared channel (PUSCH) transmission. The wireless device transmits the unused CG occasion UCI using a second CG of the plurality of CGs. The unused CG occasion UCI comprises the bitmap with the size and the bitmap indicates that the first CG is to be unused for the PUSCH transmission.

The UE capability message indicates a first capability indicating whether the wireless device supports a non-terrestrial network (NTN) access. The UE capability message indicates a second capability indicating whether the wireless device supports a multiple transport block (TB) scheduling in uplink or downlink. The UE capability messages indicates a third capability indicating whether the wireless device supports a hybrid automatic repeat request (HARQ) mode B, for multiple TBs, and corresponding logical channel prioritization (LPC) restriction for uplink transmission of multiple TBs. The wireless device receives, from the base station via the NTN access, one or more configuration parameters. The one or more configuration parameters indicate uplink multiple TB scheduling and one or more uplink HARQ processes with the HARQ mode B.

Abstract: A wireless device receives a configuration parameter indicating a threshold value used for a delay status reporting, DSR, for a logical channel group, LCG. The wireless device triggers, for a logical channel within the LCG, the DSR based on a shortest remaining time, among one or more remaining times of one or more data units buffered for the logical channel, being less than the threshold value, wherein each of the one or more remaining times indicates when to discard a respective data unit of the one or more data units. The wireless device cancels the triggered DSR in response to at least one or more conditions.

Abstract: A method can include receiving, by a wireless device, one or more discontinuous reception (DRX) configuration parameters indicating: a first DRX cycle; a DRX slot offset; and a DRX on-duration timer. The method can also include determining, for starting the DRX on-duration timer, a DRX cycle. The DRX cycle can be the first DRX cycle, based on the one or more DRX configuration parameters not indicating the second DRX cycle with the non-integer value. Alternatively, the DRX cycle can be the second DRX cycle, based on the one or more DRX configuration parameters indicating the second DRX cycle with the non-integer value. A parameter of the one or more DRX configuration parameters can indicate the non-integer value of the second DRX cycle. The method can further include starting, after the DRX slot offset from a subframe determined based on the DRX cycle, the DRX on-duration timer.

Abstract: A wireless device may start a scheduling request (SR) prohibit timer based on transmitting an SR for a transport block. The wireless device may receive, while the SR prohibit timer is running, downlink control information (DCI) indicating an uplink resource for the transport block. The wireless device may start a time window, with a duration based on a delay of a non-terrestrial network, in response to: expiration of the SR prohibit timer; the uplink resource occurring, in time, after the expiration of the SR prohibit timer; and the SR being pending. The wireless device may refrain from retransmitting the SR during the time window. The wireless device may stop the time window in response to transmitting, via the uplink resource, the transport block.

Abstract: One or more parameters may be used to configure wireless communications between a wireless device and a base station. Configuration parameters may indicate SRS resources for sounding reference signal (SRS) bandwidth aggregation of component carriers. A capability message may indicate wireless device transmission and/or reception capability for one or more bands during a guard period of SRS bandwidth aggregation. At least some component carriers may lack an uplink channel and downlink transmission may not be received during the guard period, for example, based on the capability message indicating simultaneous transmission and reception is not supported for one or more bands.

The method can further include transmitting, via the candidate cell and a time resource, an uplink transmission, wherein the time resource is after the time gap plus an offset from the time interval.

Abstract: A wireless device may communicate with a base station using transmission occasions. A number of transmission occasions for a transmission/reception may be indicated by a field and/or by an absence of a field in a message that schedules transmission/reception. For example, two physical downlink shared channel transmission occasions may be used, for scheduled transmission/reception, based on a value in a transmission configuration indicator selection field and/or based on an absence of such a field in a message.

A virtual bandwidth part for positioning frequency hopping may be used when frequency hopping takes place outside an active bandwidth part. The transmission power may be based on the virtual bandwidth part.

Abstract: A wireless device may change from communicating with a first node to communicating with a second node, for example, based on a switch or a handover. A wireless device that receives an indication for a switch (e.g., to a satellite or wireless communication device) and an indication for a handover may determine which to perform based on a time indicated for the switch. For example, the handover may be initiated after receiving an indication to perform the switch if the handover is initiated before the time for the switch.
