Claim
1. A multiple input multiple output (MIMO) system comprising:
a receiver having at least one receive antenna, wherein the receiver is configured to:
analyze one or more channel conditions of a communication with a transmitter having a plurality of transmit antennas;
based on the one or more channel conditions, select a spatial-multiplexing (SM) format for transmission in the communication and one or more transmission layers for use in the transmission, wherein the SM format is a selection of one of the defined subset of available formats; and
generate, for transmission to the transmitter, feedback information specifying the selected SM format and a number of selected transmission layers, wherein the number of selected transmission layers is included in a rank indication in the feedback information.
2. The system of claim 1, wherein the receiver is configured to:
based on one or more channel conditions, select a space time transmit diversity (STTD) format for the transmission and a grouping of the plurality of antennas for use in the transmission; and
generate, for transmission to the transmitter, feedback information specifying the selected STTD format and the grouping of the plurality of antennas.
3. The system of claim 1, wherein the transmitter comprises four antennas.
4. The system of claim 1, wherein the transmission layers are layer based water-filling is employed to provide additional gain to the system.
5. The system of claim 1, wherein the feedback information specifies beam-forming information usable by the transmitter.
6. The system of claim 1, wherein more power is transmitted to the transmission layer having better channel conditions.
7. A method for transmitting comprising:
analyzing, by a receiver, one or more channel conditions of a communication with a transmitter having a plurality of transmit antennas;
based on the one or more channel conditions, selecting, by the receiver, a spatial-multiplexing (SM) format for transmission in the communication and one or more transmission layers for use in the transmission, wherein the SM format is a selection of one of the defined subset of available formats; and
generating, by the receiver, for transmission to the transmitter, feedback information specifying the selected SM format and a number of selected transmission layers, wherein the number of selected transmission layers is included in a rank indication in the feedback information.
8. The method of claim 7, wherein,
based on one or more channel conditions, selecting, by the receiver, a space time transmit diversity (STTD) format for the transmission and a grouping of the plurality of antennas for use in the transmission; and
generating, by the receiver, for transmission to the transmitter, feedback information specifying the selected STTD format and the grouping of the plurality of antennas.
9. The method of claim 7, wherein layer based water-filling is employed to provide additional gain to the transmitter.
10. The method of claim 7, wherein the transmitter comprises four antennas.
11. The method of claim 7, wherein the feedback information specifies beam-forming information usable by the transmitter.
12. The method of claim 7, wherein more power is transmitted to the transmission layer having better channel conditions.
13. A non-transitory computer-readable storage medium with an executable program stored thereon, wherein the program instructs a processor to perform operations comprising:
analyzing one or more channel conditions of a communication with a transmitter having a plurality of transmit antennas;
based on the one or more channel conditions, selecting a spatial-multiplexing (SM) format for transmission in the communication and one or more transmission layers for use in the transmission, wherein the SM format is a selection of one of the defined subset of available formats; and
generating, for transmission to the transmitter, feedback information specifying the selected SM format and a number of selected transmission layers, wherein the number of selected transmission layers is included in a rank indication in the feedback information.
14. The non-transitory computer-readable storage medium of claim 13, wherein the operations further comprise:
based on one or more channel conditions, selecting a space time transmit diversity (STTD) format for the transmission and a grouping of the plurality of antennas for use in the transmission; and
generating, for transmission to the transmitter, feedback information specifying the selected STTD format and the grouping of the plurality of antennas.
15. The non-transitory computer-readable storage medium of claim 13, wherein layer based water-filling is employed to provide additional gain to the transmitter.
16. The non-transitory computer-readable storage medium of claim 13, wherein the transmitter comprises four antennas.
17. The non-transitory computer-readable storage medium of claim 13, wherein the feedback information specifies beam-forming information usable by the transmitter.
