Abstract

A wireless telecommunication system and method including at least two transmit antennae and means for implementing a downlink switched sub-channels diversity scheme during transmission. The method includes splitting a total bandwidth allocated for transmission of a transmitted signal to individual sub-channels or groups of sub-channels; boosting each of the sub-channels or groups of sub-channels; and routing each of the sub-channels or groups of sub-channels to a different transmit antenna.

Claims (41)

1. A method for transmission over a wireless telecommunication system utilizing OFDM (Orthogonal Frequency Division Multiplexing) or SC-FDMA (Single-Carrier Frequency Division Multiple Access), and MIMO (Multiple In Multiple Out) antenna techniques, the method comprising:

splitting a total bandwidth allocated for transmission of a signal into a plurality of groups of sub-channels;

splitting a map message associated with the signal into a plurality of map message fragments, each of the plurality of map message fragments associated with one of the groups of sub-channels from the plurality of groups of sub-channels;

splitting the plurality of groups of sub-channels into a plurality of sub-bursts, wherein each sub-burst includes one of the map message fragments;

boosting each of sub-burst of the plurality of sub-bursts; and

routing each boosted sub-burst to a different transmit antenna.

2. The method according to claim 1 , wherein said boosting includes boosting each sub-burst of the plurality of sub-bursts by a factor which is an inverse of a ratio of an aggregate group bandwidth (BW) to the total available BW.

3. The method according to claim 2 , wherein said step of routing includes providing STC (Space-Time Coding) Matrix A and routing each of said sub-channels or groups of sub-channels to a different pair of transmit antennas.

4. The method according to claim 3 , further comprising SFBC (Space-Frequency Block Coding) for LTE.

5. The method according to claim 1 , wherein said routing includes providing Cyclic Delay Diversity and routing each sub-burst of the plurality of sub-bursts to a different transmit antenna.

6. The method according to claim 1 , wherein said sub-channels are LTE resource blocks (RBs) and said groups of sub-channels are groups of RBs.

7. The wireless telecommunication method according to claim 1 , wherein the map message comprises a transmission from a downlink PUSC (Partial Usage of Sub-channels) zone.

8. The wireless telecommunication method according to claim 1 , wherein the map message comprises a portion of a WiMAX preamble.

9. The wireless telecommunication method according to claim 1 , wherein the map message comprises a portion of an AMC (Adaptive Modulation and Coding) zone transmission.

10. The method according to claim 1 , wherein said step of routing includes providing STC (Space-Time Coding) Matrix A and routing each of said sub-channels or groups of sub-channels to a different pair of transmit antennas.

11. The method according to claim 10 , further comprising SFBC (Space-Frequency Block Coding) for LTE.

12. A wireless communication system utilizing OFDM (Orthogonal Frequency Division Multiplexing) or SC-FDMA (Single-Carrier Frequency Division Multiple Access), and MIMO (Multiple In Multiple Out) antenna techniques, the system comprising:

a transmitter including at least two transmit antennas;

split the plurality of groups of sub-channels into a plurality of sub-bursts, wherein each sub-burst includes one of the map message fragments; and

beam forming hardware in the transmitter configured to:

boost each sub-burst of the plurality of sub-bursts; and

route each boosted sub-burst to a different transmit antenna.

13. The wireless telecommunication system of claim 12 , wherein the map message comprises a transmission from a downlink PUSC (Partial Usage of Sub-channels) zone.

14. The wireless telecommunication system of claim 12 , wherein the map message comprises a portion of a WiMAX preamble.

15. The wireless telecommunication system of claim 12 , wherein the map message comprises a portion of an AMC (Adaptive Modulation and Coding) zone transmission.

16. An apparatus for transmitting over a wireless telecommunication system utilizing OFDM (Orthogonal Frequency Division Multiplexing) or SC-FDMA (Single-Carrier Frequency Division Multiple Access), and MIMO (Multiple In Multiple Out) antenna techniques, the apparatus comprising:

means for splitting a total bandwidth allocated for transmission of a signal into a plurality of groups of sub-channels;

means for splitting a map message associated with the signal into a plurality of map message fragments, each of the plurality of map message fragments associated with one of the groups of sub-channels from the plurality of groups of sub-channels; and
