Abstract

A method for data receiving at a base station is provided. The base station receives data using a first transmission resource in a first symbol of an uplink control channel from a first UE. The base station receives UL data or control information using a second transmission resource in a second symbol of the uplink control channel from a second UE as well. The first symbol and the second symbol have different numerologies at a same sub band.
