Cooperative communication in a cellular network (cooperative communications)

摘要

A method is provided for communications in a cellular network (1) comprising a plurality of mobile stations (MS1 to MS3) adapted for performing wireless communications with at least one base station (BS1, BS2) using a first transmission technology, the method comprising: forming a cooperating cluster (C) comprising two or more of the mobile stations (MS1, MS2), and performing short-range communications between the mobile stations (MS1, MS2) of the cooperating cluster (C) using a second transmission technology being different from the first transmission technology for improving, for at least one mobile station (MS1, MS2) of the cluster (C), the performance of the wireless communications with the base station (BS), preferably by using MIMO techniques for at least one of interference suppression and cancellation, in particular by using at least one of transmit precoding for uplink transmissions and receive antenna weighting for downlink reception. A mobile station (MS1, MS2) for forming a cooperating cluster (C), a cooperating cluster (C) comprising at least one such mobile station (MS1, MS2), and a cellular network (1) are also provided.
