In this paper, we consider resource allocation in the the fourth generation
(4G) cellular uplink. Our focus is on 4G cellular systems that conform to the
3GPP LTE standard and its enhancements, which are expected to be the
predominant 4G cellular systems. In order to cater to an ever-increasing user
traffic, the 4G uplink allows for precoded multi-stream (precoded MIMO)
transmission from each scheduled user and also allows multi-user (MU)
scheduling wherein multiple users can be assigned the same time-frequency
resource.
