Abstract:
In a coordinated multipoint system, geographically distributed base transceiver stations employ overlapping coverage areas in a Radio Access Network (RAN) to serve multiple User Equipments (UEs). A fronthaul network communicatively couples the base transceiver stations to a central processor. The central processor comprises a cooperative multiple-input, multiple-output (MIMO) processor configured to select multiple antennas residing on multiple ones of the base transceiver stations to serve each of the UEs; compute baseband pre-coding weights for signals to be transmitted by the antennas, the baseband pre-coding weights computed from RAN channel state information between the antennas and the UEs; and coordinate transmissions of pre-coded signals from the antennas to exploit multipath in the RAN to coherently combine at each of the UEs. Since each UE can be provided with its own localized coherence zone, this enables the UEs to concurrently employ the same frequency spectrum.
