1. A primary station comprising:
- a plurality of antennas configured to communicate over a plurality of paths between the primary station and a secondary station;
at least one processing circuit configured to;
receive a first message from the secondary station indicating a number of simultaneous data streams that the secondary station is capable of receiving or processing;
subsequent to receiving the first message, transmit a plurality of data packets substantially simultaneously to the secondary station such that each data packet is transmitted via a different subset of the plurality of paths; and
receive a second message including a positive acknowledgment (ACK) for each of the plurality of data packets that are received correctly and a negative acknowledgment (NACK) for each of the plurality of data packets that are not received correctly, wherein the second message utilizes a same uplink channel for transmission of each positive acknowledgment (ACK) or negative acknowledgment (NACK) that are received in response to the plurality of data packets that are transmitted substantially simultaneously, and wherein the second message includes one of an ACK or a NACK for individually indicating the status of each of the plurality of data packets.

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. The secondary station receives the plurality of data packets, determines whether each packet is received correctly and signals this determination as an acknowledgement or a negative acknowledgement to the primary station for each of the plurality of packets.

10. A secondary station comprising:
-
at least one antenna configured to communicate over a plurality of paths between the secondary station and a primary station; at least one processing circuit configured to; transmit, via the at least one antenna, a first message to the primary station indicating a number of simultaneous data streams that the secondary station is capable of receiving or processing; subsequent to transmitting the first message, receive, via the at least one antenna, a plurality of data packets that were transmitted substantially simultaneously by the primary station; determine whether each data packet is received correctly; transmit, via the at least one antenna, a second message to the primary station including a positive acknowledgment (ACK) for each of the plurality of data packets that are received correctly and a negative acknowledgment (NACK) for each of the plurality of data packets that are not received correctly, wherein the second message utilizes the same uplink channel for transmission of each positive acknowledgment (ACK) or negative acknowledgment (NACK) that are transmitted in response to the plurality of data packets that were transmitted by the primary station substantially simultaneously, and wherein the second message includes one of an ACK or a NACK for individually indicating the status of each of the plurality of data packets. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
