For user equipments (UEs) configured to handle multiple numerologies, different rules for mapping logical channels associated with different numerologies may be defined for data and non-data channels. Thus, when new data arrives at a UE for communication via a logical channel associated with a different numerology, the UE checks whether the mapping rules would allow multiplexing of the new numerology data onto an existing data channel. If no data channel has already been allocated or if an allocated data channel may not include data from the new numerology, then a mapping is followed for specifically requesting resources for communication of the new numerology data. The new mapping may trigger scheduling request or random access procedures specifically associated with the new numerology. ## Claims ### Claim 1 A method of wireless communication, comprising: obtaining data at a user equipment (UE) for uplink communications, wherein the data is identified for transmission on a first logical channel and first numerology;
