Abstract
A mechanism to help facilitate uplink communication from multiple user equipment devices (UEs) to a base station on shared air interface resources, i.e., with the multiple UEs transmitting to the base station on the same subcarriers and at the same time as each other. The mechanism makes use of successive interference cancellation (SIC) and non-orthogonal coding to help distinguish and separate the UEs' transmissions from each other and thus to help the base station separately process each UE's transmission even though the UEs transmit to the base station on the same air interface resources as each other.
