A user equipment (UE) receives first configuration information for one or more numerology sets, each numerology set including one or more numerologies. The UE receives second configuration information for one or more logical channels, each logical channel mapped to one or more numerologies. The UE receives a first uplink (UL) grant for new transmission, the first UL grant including information indicating a numerology set associated with the first UL grant. The UE generates a MAC PDU. The UE performs a new transmission of the MAC PDU using the first UL grant. The MAC PDU contains data from a logical channel of which every numerology belongs to the numerology set.
