Wireless communications wherein modulation schemes for dominant interfering devices are selected to both use real symbols or complex symbols

摘要

A wireless network wherein access points (AP)/base stations and mobile terminals select modulation schemes such that a wanted signal and a dominant interfering signal both use real valued modulation or both use complex valued modulation. Matching modulation types may improve interference rejection capabilities (IRC). The communications may be between APs and terminal devices (uplink/downlink) or may be between terminal devices (D2D). A mobile terminal may determine the type of interference that it is subjected to (real/complex) and may then request that an AP use the same type of modulation for communication 40. The AP may then make a determination 42 about whether to use real/complex valued modulation and communicate 46 on that basis. Access points/cells may also advise each other of modulation schemes to be employed and thereby co-ordinate the selection of modulation schemes to achieve all real/complex signals and interference. Selection of modulation schemes may also involve path loss information and signal to interference and noise ratios (SINR).
