Method and wireless device for performing uplink transmission timing control

A wireless device comprising processing circuitry and memory, the memory containing instructions executable by the processing circuitry whereby the wireless device is configured to:

• obtain a window of time for bundling for a set of uplink transmissions on a bandwidth part, wherein the bundling is for keeping power consistency and phase continuity, wherein the bundling is demodulation reference signal (DMRS) bundling;
• make a determination of whether or not to apply a timing advance adjustment within the window of time, wherein the timing advance adjustment comprises an adjustment to a transmission timing of an uplink transmission in the set of uplink transmissions, wherein the determination is:
• a determination to apply the timing advance adjustment within the window of time if the timing advance adjustment is indicated by a received timing advance command;
• and
• a determination to not apply the timing advance adjustment within the window of time if the timing advance adjustment is due to a detected error in downlink timing;
• and
• transmit the uplink transmission on the bandwidth part during the window of time using a transmission timing which is in accordance with the determination.
