Techniques and apparatuses for using different timing advance values for different numerologies

A method of wireless communication performed by a base station, comprising:

• determining a numerology to be used to calculate a timing offset to be applied to adjust a timing of an uplink transmission;
• determining a timing value for calculating the timing offset based at least in part on the numerology, wherein different timing values are determined for different numerologies;
• and
• transmitting a timing advance (TA) command that includes the timing value,
• wherein the timing value includes a first set of bits used to calculate an unadjusted timing offset using a first granularity and a second set of bits used to calculate the timing offset by adjusting the unadjusted timing offset using a second granularity that is finer than the first granularity.

A user equipment (UE) for wireless communication, comprising:

• memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• receive a timing advance (TA) command that includes a timing value for calculating a timing offset to be applied to adjust a timing of an uplink transmission,
• wherein the timing value includes a first set of bits used to calculate an unadjusted timing offset using a first granularity and a second set of bits used to calculate the timing offset by adjusting the unadjusted timing offset using a second granularity that is finer than the first granularity;
• determine a numerology to be used to calculate the timing offset from the timing value;
• calculate the timing offset using the timing value and the numerology, wherein the timing value corresponds to different timing offsets for different numerologies;
• and
• send the uplink transmission according to the timing offset.
