Abstract
A communication system comprises a set of user equipments which are arranged to simultaneously transmit a signal over an air interface to a base station. Each of the transmitted signals comprises a data stream encoded by a space time block code and transmitted on multiple antennas. Specifically, an Alamouti code may be used. The base station generates a received data stream for each of the set of user equipments by joint space time block code decoding of the signals from the set of user equipments. The invention may provide improved performance and increased capacity and may in particular provide efficient multi user operation for a system using space time block codes. The user equipments may be scheduled in response to cross interference metrics reflecting a cross interference between simultaneously transmitting user equipments.
