System and method for distributed antenna wireless communications
First Claim
1. A method implemented within a wireless transmission system comprised of a plurality of wireless client devices, a base station, and a plurality of distributed transceiver devices communicatively coupled to the base station comprising:
- simultaneously transmitting pre-coded radio signals from the plurality of distributed transceiver devices, the pre-coding creating deliberate radio frequency interference comprising a controlled constructive and destructive interference of RF waveforms so as to enable data reception upon each receiving antenna and resulting in a simultaneous plurality of non-interfering channels within a common frequency between the plurality of distributed transceiver devices and the plurality of wireless client devices.

Abstract
A system and method are described for distributed antenna wireless communications. For example, a method implemented within a wireless transmission system comprised of a plurality of wireless client devices and a plurality of distributed antennas is described comprising: computing channel state information (CSI) for wireless communication channels between the plurality of base distributed antennas and the wireless client devices; computing precoding weights from the channel state information; precoding data using the precoding weights prior to wireless transmission from the plurality of distributed antennas to the wireless client devices; and wirelessly transmitting the precoded data from the distributed antennas to each of the wireless client devices, wherein the precoding causes radio frequency interference between the plurality of base stations but simultaneously generating a plurality of non-interfering radio frequency user channels between the plurality of distributed antennas and the plurality of wireless client devices.

18. A wireless transmission system comprising:
-
a plurality of wireless client devices; one or more base transceiver stations (BTSs); a plurality of distributed transceiver devices communicatively coupled to the BTSs over a base station network (BSN), wherein the BTSs precode data streams for simultaneous transmission from each of the distributed transceiver devices to the plurality of wireless client devices, the precoding creating deliberate radio frequency interference comprising a controlled constructive and destructive interference of RF waveforms so as to enable data reception upon each receiving antenna and resulting in a simultaneous plurality of non-interfering channels within a common frequency between the plurality of distributed transceiver devices and the plurality of wireless client devices. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
