Method and apparatus to facilitate support for multi-radio coexistence

Abstract

A method of wireless communication by user equipment (UE) identifies a coexistence issue corresponding to a set of communication resources of the UE. The UE transmits, to a base station, an indication of the coexistence issue. The UE receives, from the base station, a communication parameter for selectively scheduling a measurement gap pattern. The UE communicates in accordance with the measurement gap pattern to mitigate the coexistence issue.
