Abstract
There is disclosed a system and method wherein signals generated by a mobile station and received at multiple base transceiver stations, are combined utilizing signal processing techniques. Signals received at non-target Base station transceivers are directed, by each non-target BTS, to a target BTS where a combiner is utilized to assemble the received signals (bits) into a packet, or frame, and to determine if an error condition exists. The error condition of the frame or packet determines whether to utilize BTS power control circuitry to notify the mobile station to adjust the mobile station transmit power up or down.
Claims20
For use in a wireless network, a distributed architecture for the reception of signals transmitted from one or more mobile stations, comprising:
- a plurality of base transceiver stations for receiving said signals;
- a Code Division Multiple Access (CDMA) detector in each said base transceiver station;
- and
- a combiner in each said base transceiver station for combining a first signal received by a target Base transceiver station with signals transmitted to said target base transceiver station by said plurality of base transceiver stations.
A wireless office network, comprising:
- a mobile switching center;
- a plurality of Base Stations each comprising a base station controller and at least one base transceiver station;
- a backhaul network for connecting said mobile switching center with each said Base Station Subsystem;
- and
- a distributed architecture for the reception of signals transmitted from one or more mobile stations, comprising:
- a plurality of base transceiver stations for receiving said signals;
- a Code Division Multiple Access (CDMA) detector in each of said plurality of base transceiver stations;
- and
- a combiner in each said base transceiver station for combining a first signal received by a target base transceiver station with signals transmitted to said target base transceiver station by said plurality of said non- target base transceiver stations.
For use in a wireless network, a method for receiving signals transmitted from one or more mobile stations, comprising the steps of:
- detecting a baseband signal from a mobile station at a plurality of base transceiver stations, one station being a target base transceiver station;
- producing a symbol based on a detector output determined from said baseband signal received at each non-target base transceiver station;
- combining said non-target base transceiver station symbols with said target base transceiver station symbol;
- and
- sending a power adjustment signal to said mobile station.
