RADIO COMMUNICATION SYSTEM
First Claim
1. A radio communication system having a communication channel comprising:
- a primary station having a plurality of antennas;
a secondary station having at least one antenna; and
a plurality of paths between the primary station and the secondary station, the primary station further comprising means for transmitting substantially simultaneously a plurality of data packets to the secondary station, each data packet being transmitted via a different subset of the plurality of paths, andthe secondary station further comprising means for receiving the plurality of data packets, for determining whether each data packet is received correctly, for notifying the primary station whether each data packet is received correctly, and for sending the primary station an indication of a number of simultaneous data streams that the secondary station is capable of receiving or processing.

Abstract
A radio communication system comprises a communication channel for the transmission of data packets from a primary station having a plurality of antennas to a secondary station having at least one antenna. The channel comprises a plurality of paths, and the primary station transmits a plurality of packets substantially simultaneously. Each of the plurality of packets is transmitted via a different subset of the plurality of paths, for example by arranging for each packet to be transmitted via a different antenna or antenna beam.
The secondary station receives the plurality of data packets, determines whether each packet is received correctly and signals this determination (typically as an acknowledgement or a negative acknowledgement to the primary station for each of the plurality of packets. The signalling may be by any convenient means, for example transmitting each acknowledgement or negative acknowledgement via a different subset of available uplink paths.
