SYSTEMS AND METHODS FOR MAPPING VIRTUAL RADIO INSTANCES INTO PHYSICAL VOLUMES OF COHERENCE IN DISTRIBUTED ANTENNA WIRELESS SYSTEMS

摘要

Systems and methods are described for mapping Virtual Radio Instances (VRIs) into physical volumes of coherencein a Multiple Antenna System (MAS) with Multi-User (MU) transmissions (“MU-MAS”). These mapping methods enable communications through simultaneous non-interfering data streams in the same frequency band between the MU-MAS and multiple users, within their own volume of coherence. As the users move, their VRIs follow their respective volumes of coherence via teleportation to adjacent MU-MAS networks, thereby eliminating the need for handoffs as in conventional cellular systems and unnecessary control data overhead.

1. A multiuser-multiple antenna system (“MU-MAS”) comprising of:
a first plurality of waveforms; one or more processing units precoding the first plurality of waveforms into a second plurality of waveforms that are concurrently transmitted at the same carrier frequency; wherein the second plurality of waveforms combine in a plurality of volumes in space such that in each one of the plurality of volumes in space one of the first plurality of waveforms can be demodulated by one of a plurality of user devices;
