Dynamic configuration of measurement gaps
Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a serving base station via higher layer signaling, a plurality of measurement gap configurations, receives, from the serving base station via lower layer signaling, an activation of a first measurement gap configuration of the plurality of measurement gap configurations, and performs one or more measurements of one or more non-serving base stations during measurement gaps specified by the first measurement gap configuration. Other techniques related to dynamic configuration of measurement gap configurations are also disclosed.
