Application time for non-serving cell reference signal update

A network entity for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to:
• transmit, to a UE, an indication of an update associated with a non-serving cell reference signal of a non-serving cell;
• select an application time duration from a first application time duration and a second application time duration based at least in part on receiving the indication of the update, the first application time duration being selected based at least in part on a determination that the non-serving cell reference signal has been tracked by the UE and the second application time duration being selected based at least in part on a determination that the non-serving cell reference signal has not been tracked by the UE, resulting in a selected application time duration;
• apply the update associated with the non-serving cell reference signal after the selected application time duration;
• receive, from the UE, a UE capability report indicating at least one of a first duration value associated with a tracked non-serving cell reference signal or a second duration value associated with a non-tracked non-serving cell reference signal;
• and
• determine at least one of the first application time duration or the second application time duration based at least in part on the at least one of the first duration value or the second duration value.

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

• receiving, from a network entity, an indication of an update associated with a non-serving cell reference signal of a non-serving cell, wherein the indication includes an indication to use the non-serving cell reference signal as a path loss reference signal for an uplink channel, and wherein a determination of whether the non-serving cell reference signal has been tracked by the UE is based at least in part on a determination of whether the non-serving cell reference signal has been configured as a path loss reference signal for the UE;
• selecting an application time duration from a first application time duration and a second application time duration based at least in part on receiving the indication of the update, the first application time duration being selected based at least in part on a determination that the non-serving cell reference signal has been tracked by the UE and the second application time duration being selected based at least in part on a determination that the non-serving cell reference signal has not been tracked by the UE, resulting in a selected application time duration;
• and
• applying the update associated with the non-serving cell reference signal after the selected application time duration, wherein applying the update associated with the non-serving cell reference signal comprises:
• transmitting, after the selected application time duration, an uplink communication on the uplink channel using a transmission power determined from a path loss estimation based at least in part on measurements of the non-serving cell reference signal.

• and
• determining at least one of the first application time duration or the second application time duration based at least in part on the at least one of the first duration value or the second duration value.
