A wireless device receives a first configured grant (CG) configuration, associated with a first CG index, comprising one or more parameters indicating to disable: monitoring for retransmissions corresponding to the first CG configuration; and starting a discontinuous reception (DRX) hybrid automatic repeat request (HARQ) round trip time (RTT) timer for a HARQ process associated with a transport block (TB) transmitted via a CG resource indicated by the first CG configuration. The wireless device receives a second CG configuration not associated with the first CG index. Based on the first CG configuration, the wireless device does not start a first DRX HARQ RTT timer for a first HARQ process, and based on the second CG configuration, the wireless device starts a second DRX HARQ RTT timer for a second HARQ process.

Handling on retransmission for extended reality

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.

Methods and apparatuses for determining a discontinuous reception (DRX) cycle

A method can include transmitting, by a wireless device, a capability message comprising a field indicating a time gap of the wireless device to complete a procedure of layer 1 or layer 2 triggered mobility (LTM). The method can also include receiving, in a time interval, a medium access control control element (MAC CE) indicating cell switch to a candidate cell of LTM. 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.

Timing advance for mobility

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.

A wireless device drops sounding reference signal (SRS) transmissions, in SRS resources linked for bandwidth aggregation, that conflict in time with a transmission or a reception scheduled by downlink control information (DCI). A time period between a last symbol of the DCI and a starting symbol of the SRS transmissions is equal to, or greater than, a number of symbols plus a guard period of the bandwidth aggregation.

Collision timeline for bandwidth aggregation

A wireless device receives a configured grant (CG) configuration indicating: a period of the CG configuration, and a number of consecutive slots for transmission occasions within the period. The wireless device transmits uplink data, via a transmission occasion of the transmission occasions. A hybrid automatic repeat request (HARQ) process index (ID) for transmission of the uplink data is based on: the number of consecutive slots for the transmission occasions within the period, and an offset for the transmission occasion of the transmission occasions within the period. The offset is based on an order of the transmission occasion among the transmission occasions within the period.
