1. A method for mobile communication, comprising:
- arranging a plurality of access points in a wireless local area network (WLAN) to communicate on a common frequency channel with a mobile station;
receiving at one or more of the access points an uplink signal transmitted over the WLAN by the mobile station on the common frequency channel;
arbitrating among the access points receiving the uplink signal so as to select one of the access points to respond to the uplink signal; and
transmitting a response from the selected one of the access points to the mobile station.

Abstract
A method for mobile communication includes arranging a plurality of access points in a wireless local area network (WLAN) to communicate on a common frequency channel with a mobile station. Upon receiving at one or more of the access points an uplink signal transmitted over the WLAN by the mobile station on the common frequency channel, the access points receiving the uplink signal arbitrate among themselves so as to select one of the access points to respond to the uplink signal. A response is then transmitted from the selected one of the access points to the mobile station.

13. A system for mobile communication, comprising:
-
a communication medium; and
a plurality of access points interconnected by the medium and arranged in a wireless local area network (WLAN) to communicate on a common frequency channel with a mobile station, the access points being adapted, upon receiving at one or more of the access points an uplink signal transmitted over the WLAN by the mobile station on the common frequency channel, to arbitrate among the access points receiving the uplink signal by sending messages over the medium so as to select one of the access points to respond to the uplink signal, and to transmit a response from the selected one of the access points to the mobile station. - View Dependent Claims (14, 15, 16, 24)

25. Access point apparatus for deployment in a wireless local area network (WLAN) as one of a plurality of access points for mobile communication, the apparatus comprising:
-
a radio transceiver, which is configured to communicate on a predetermined frequency channel with a mobile station; and
a message processor, which is adapted, when the transceiver receives an uplink signal transmitted over the WLAN by the mobile station on the predetermined frequency channel, to carry out an arbitration protocol together with others of the access points receiving the uplink signal so as to select one of the access points to respond to the uplink signal, and to control the transceiver so that the transceiver returns a response to the mobile station subject to the arbitration protocol. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33)
