US 6,549,772 B1 · Multiple antenna cellular network

Abstract

A multiple antenna cellular network communicates with a mobile station over a plurality of antennas. The antennas are arranged in a plurality of positions to customize a cell or cells. A transceiver is coupled to the antennas and configured to receive inbound information from the mobile station and transmit outbound information to the mobile station. A processor is coupled to the transceiver and configured to decode the inbound information and to encode the outbound information to communicate with the mobile station. In another embodiment, the transmit signal power is continuously modified to move interference nulls to improve quality so that a fixed location user can receive a high quality signal. Exemplary embodiments are provided for use with the Global Systems for Mobile Communication (GSM) protocol and can be applied to other digital technologies.

Dependent claims

A multiple antenna cellular network for communicating with a mobile station within a cell, comprising:

a plurality of antennas positioned to produce the cell;
a transceiver coupled to said antennas and configured to receive inbound information from said mobile station and transmit outbound information to said mobile station, said transceiver including a plurality of remote transceivers each coupled to said antennas and a local transceiver coupled to a processor and coupled to said remote transceivers, wherein a control word containing address information and configuration information for individual remote transceivers is transmitted between the local transceiver and the remote transceivers such that the local transceiver uses the control word to individually configure said each remote transceiver to vary outbound information output power to move nulls in the cell;
said processor coupled to said transceiver and configured to decode said inbound information and to encode said outbound information to communicate with said mobile station.

A method of communicating with a mobile station in a cell using a multiple antenna cellular network having a plurality of antennas positioned to produce the cell, a plurality of remote transceivers coupled to said antennas and configured to receive inbound information from said mobile station and transmit outbound information to said mobile station, a local transceiver coupled to said remote transceivers and to a processor configured to decode said inbound information and to encode said outbound information to communicate with said mobile station, said method comprising the steps of:

transmitting a control word containing address information and configuration information for individual remote transceivers between the local transceiver and the remote transceivers;
individually configuring said each remote transceiver using said control word to vary outbound information output power to move nulls in the cell;
simultaneously transmitting outbound information by each remote transceivers;
and
receiving inbound information by at least one remote transceiver.
