Cross-carrier reference signal scheduling offset and threshold determination

A method of wireless communication performed by a user equipment (UE), comprising:

• receiving, from a wireless communication device and via a first carrier, an indication of an offset for scheduling a reference signal on a second carrier, that indicates a duration between downlink control information (DCI), that schedules the reference signal, and the reference signal,
• the offset being based on a scheduling offset threshold indicating a minimum duration for the UE to switch to a different beam;
• determining a first numerology of the first carrier and a second numerology of the second carrier;
• and
• determining a time offset for the reference signal based at least in part on the offset and at least one of the first numerology, the second numerology, or both the first numerology and the second numerology.

A base station for wireless communication, comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• receive, from a user equipment (UE), an indication of multiple scheduling offset thresholds corresponding to multiple numerologies, that indicates, for a corresponding numerology, a minimum duration between downlink control information (DCI) and a reference signal associated with the DCI;
• determine a first numerology of a first carrier of the UE and a second numerology of a second carrier of the UE;
• determine a scheduling offset threshold, of the multiple scheduling offset thresholds, based at least in part on the first numerology, the second numerology, or both the first numerology and the second numerology,
• the scheduling offset threshold indicating the minimum duration for the UE to switch to a different beam;
• and
• schedule a reference signal, with a scheduled offset between the DCI and the reference signal, for the UE based at least in part on the scheduling offset threshold.
