Abstract

A system and method is disclosed for providing concurrent data transmissions in a wireless communication network. The invention comprises a register unit within a base transceiver station that prepares data packets to be transmitted to mobile stations within a plurality of cell sectors. The register unit identifies the cell sector destination of each data packet in a first data call and sends the data packet to a buffer associated with the cell sector destination. The buffers store their respective data packets for each cell sector in a first subframe of a data frame. The buffers send their respective data packets within the first subframe to their respective antennas. The data packets for each cell sector are then concurrently transmitted during the first subframe. Data packets of a second data call are transmitted during the second and third subframe so that two data calls are concurrently transmitted.

Claims

1. For use in a wireless network, a base station comprising an antenna array capable of transmitting forward channel data into S sectors associated with said base station, wherein said base station

receives a plurality of data packets in a first data frame of a wireline connection,

associates a first one of said received data packets with a corresponding first one of said S sectors,

associates a second one of said received data packets with a corresponding second one of said S sectors, said first and second sectors being different ones of said S sectors, and

concurrently transmits said first and second data packets in said corresponding first and second sectors during a first subframe of a first forward channel data frame,

and wherein said first data frame of said wireline connection has a duration T, said first forward channel data frame has a duration T, and said first subframe has a duration less than T.

2. The base station as set forth in claim 1, wherein said base station is further capable of transmitting a first additional data packet associated with said first sector in said first sector during a period of said first forward channel data frame following said first subframe.

3. The base station as set forth in claim 2, wherein said base station is further capable of transmitting a second additional data packet associated with said second sector in said second sector during said period of said first forward channel data frame following said first subframe.

4. The base station as set forth in claim 3, wherein said base station transmits said first additional data packet and said second additional data packet sequentially.

5. The base station as set forth in claim 1, wherein said base station is further capable of transmitting a first additional data packet associated with said first sector in said first sector in a first dedicated time slot of said first forward channel data frame following said first subframe.

6. The base station as set forth in claim 5, wherein said base station is further capable of transmitting a second additional data packet associated with said second sector in said second sector in a second dedicated time slot of said first forward channel data frame following said first subframe.

7. The base station as set forth in claim 6, wherein said first dedicated time slot and said second dedicated time slot are sequential time slots.

8. A wireless network comprising a plurality of base stations capable of communicating with a plurality of mobile stations in a coverage area of said wireless network,

wherein a first one of said plurality of base stations comprises an antenna array capable of transmitting forward channel data into S sectors associated with said first base station, and

wherein said first base station

receives a plurality of data packets in a first data frame of a wireline connection,

associates a first one of said received data packets with a corresponding first one of said S sectors,

associates a second one of said received data packets with a corresponding second one of said S sectors, said first and second sectors being different ones of said S sectors, and

concurrently transmits said first and second data packets in said corresponding first and second sectors during a first subframe of a first forward channel data frame,

and wherein said first data frame of said wireline connection has a duration T, said first forward channel data frame has a duration T, and said first subframe has a duration less than T.

9. The wireless network as set forth in claim 8, wherein said first base station is further capable of transmitting a first additional data packet associated with said first sector in said first sector during a period of said first forward channel data frame following said first subframe.

10. The wireless network as set forth in claim 9, wherein said first base station is further capable of transmitting a second additional data packet associated with said second sector in said second sector during said period of said first forward channel data frame following said first subframe.

11. The wireless network as set forth in claim 10, wherein said first base station transmits said first additional data packet and said second additional data packet sequentially.

12. The wireless network as set forth in claim 11, wherein said first base station is further capable of transmitting a first additional data packet associated with said first sector in said first sector in a first dedicated time slot of said first forward channel data frame following said first subframe.

13. The wireless network as set forth in claim 12, wherein said first base station is further capable of transmitting a second additional data packet associated with said second sector in said second sector in a second dedicated time slot of said first forward channel data frame following said first subframe.

14. The wireless network as set forth in claim 13, wherein said first dedicated time slot and said second dedicated time slot are sequential time slots.

15. For use in a base station of a wireless network, a method of transmitting forward channel data into S sectors associated with the base station comprising the steps of:

receiving in the base station a plurality of data packets in a first data frame of a wireline connection;

associating a first one of the received data packets with a corresponding first one of the S sectors;

associating a second one of the received data packets with a corresponding second one of the S sectors, wherein the first and second sectors are different ones of the S sectors; and

transmitting concurrently the first and second data packets in the corresponding first and second sectors during a first subframe of a first forward channel data frame,

wherein the first data frame of the wireline connection has a duration T, the first forward channel data frame has a duration T, and the first subframe has a duration less than T.

16. The method as set forth in claim 15, further comprising the steps of:

transmitting a first additional data packet associated with the first sector in the first sector during a period of the first forward channel data frame following the first subframe; and

transmitting a second additional data packet associated with the second sector in the second sector during the period of the first forward channel data frame following the first subframe.

17. The method as set forth in claim 16, wherein the first additional data packet and the second additional data packet are transmitted sequentially.
