Timing Advance Indication for a Beam During Handover

A wireless device comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
• receive a radio resource control (RRC) message indicating a handover to a cell, the RRC message indicating:
• a first timing advance of a first beam of the cell;
• and
• a second timing advance of a second beam of the cell;
• select, as a selected beam of the cell, one of the first beam or the second beam;
• and
• transmit, via the selected beam, transport blocks using one of the first timing advance or the second timing advance corresponding to the selected beam.

A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to:

• receive a radio resource control (RRC) message indicating a handover to a cell, the RRC message indicating:
• a first timing advance of a first beam of the cell;
• and
• a second timing advance of a second beam of the cell;
• select, as a selected beam of the cell, one of the first beam or the second beam;
• and
• transmit, via the selected beam, transport blocks using one of the first timing advance or the second timing advance corresponding to the selected beam.
