Aspects are provided which allow a first wireless device such as a UE or base station to prioritize beams which are simultaneously received from or transmitted to cells of different numerologies or which are asynchronous to each other. The device determines an overlap in time between a first signal from a first cell and a second signal from a second cell, where the second cell includes at least one of a different numerology than the first cell or an asynchronous timing relative to the first cell. The device applies a beam prioritization rule for selecting a beam associated with the first signal or the second signal carrying information in separate beams. The device transmits information to or receives information from a second wireless device based on the selected beam. Thus, simultaneous beam conflict resolution may be improved for cells having different numerologies or asynchronous timing.
