Abstract

Embodiments of inventive concepts are provided wherein a plurality of mobile devices, such as, for example, a plurality of smartphones, may transmit information to a base station concurrently in time and co-frequency therebetween in order to increase spectral efficiency and/or channel throughput. Embodiments comprising pre-processing at the mobile devices and/or post-processing at the base station may be used to reduce interference. Inventive concepts of a base station transmitting to a plurality of mobile devices concurrently in time and co-frequency therebetween are also presented. Embodiments are presented comprising pre-processing at the base station and/or post-processing at the mobile devices to reduce interference.
