Radio communication system
First Claim
1. A radio communication system comprising a primary station having at least two antennas and at least two secondary stations each having at least one antenna, wherein the primary station comprises means for transmitting respective communication channels between the primary station and first and second secondary stations from respective mutually exclusive subsets of the primary station'"'"'s antennas, wherein the first and second secondary stations are in the coverage area of the primary station antennas in both subsets, wherein the respective channels are distinguished solely by the respective subsets of antennas, and wherein the first and second secondary stations each comprise means for estimating from the received signals the subset of signals comprising its respective communication channel.

Abstract
A radio communication system comprises a primary station (100) and at least two secondary stations (110a, 110b), each of which comprises at least one antenna (108, 118). The primary station is arranged to transmit respective communication channels to each of the secondary stations from respective mutually exclusive subsets of its antennas (108). The communication channels are defined solely by the respective subsets of antennas (108), and each secondary station has means (414) for extracting from the received signals the subset comprising its respective communication channel.

- 1. A radio communication system comprising a primary station having at least two antennas and at least two secondary stations each having at least one antenna, wherein the primary station comprises means for transmitting respective communication channels between the primary station and first and second secondary stations from respective mutually exclusive subsets of the primary station'"'"'s antennas, wherein the first and second secondary stations are in the coverage area of the primary station antennas in both subsets, wherein the respective channels are distinguished solely by the respective subsets of antennas, and wherein the first and second secondary stations each comprise means for estimating from the received signals the subset of signals comprising its respective communication channel.
- 4. A primary station having at least two antennas for use in a radio communication system having at least two secondary stations, wherein means are provided for transmitting respective communication channels between the primary station and first and second secondary stations from respective mutually exclusive subsets of the primary station'"'"'s antennas, wherein the first and second secondary stations are in the coverage area of the primary station antennas in both subsets, and wherein the respective channels are distinguished solely by the respective subsets of antennas.
- 7. A secondary station having at least one antenna for use in a radio communication system having respective communication channels between a primary station having at least two antennas, the secondary station and a further secondary station, wherein the communication channels are transmitted from respective mutually exclusive subsets of the primary station'"'"'s antennas, wherein the secondary station and the further secondary station are in the coverage area of the primary station antennas in both subsets, wherein the respective channels are distinguished solely by the respective subsets of antennas, and wherein means are provided for estimating from the received signals the subset of signals comprising the secondary station'"'"'s respective communication channel.
