Abstract
To perform wireless communications in a closed loop multiple input multiple output (MIMO) system a feedback data structure is communicated over a wireless channel between a first wireless node and a second wireless node where the feedback data structure contains indicators identifying coding to be applied by the second wireless node on signaling communicated between the second wireless node and the first wireless node where the information in the feedback data structure is based on wireless channel conditions detected at the first wireless node. The indicators identify different codings to be used for different corresponding bands in the wireless channel.

Claim
1. A method of wireless communications in a closed loop multiple input, multiple output (MIMO) system, comprising: communicating, over a wireless channel between a first wireless node and a second wireless node, a feedback data structure containing indicators identifying codings to be applied on signaling communicated between the second wireless node and the first wireless node, wherein the indicators in the feedback data structure are based on wireless channel conditions detected at the first wireless node, and wherein the indicators correspond to plural bands in the wireless channel.
2. The method of claim 1, wherein communicating the feedback data structure between the first and second wireless nodes comprises communicating the feedback data structure between a mobile station and a base station.
3. The method of claim 1, wherein communicating the feedback data structure containing the indicators comprises communicating the feedback data structure containing precoding matrix index (PMI) values for the corresponding bands.
4. The method of claim 3, further comprising: selecting, by the second wireless node, an entry of a codebook based on each of the PMI values, wherein the codebook contains a plurality of entries containing respective precoding matrices, wherein each precoding matrix is used to apply coding on signaling transmitted by the second wireless node to the first wireless node.
5. The method of claim 3, wherein the feedback data structure further contains a channel quality indicator and rank information, and wherein the method further comprises: selecting, by the second wireless node, a modulation and coding scheme based on the channel quality indicator; and selecting, by the second wireless node, a number of data streams based on the rank information..
6. The method of claim 1, further comprising: the second wireless node overriding coding recommended by the mobile station based on the indicators; and the second wireless node sending an indication of changed coding to the mobile station.
7. The method of claim 1, wherein communicating the feedback data structure comprises communicating WiMAX (Worldwide Interoperability for Microwave Access) feedback headers.
8. The method of claim 7, wherein communicating the WiMAX feedback headers comprises communicating a WiMAX feedback header of a first type and a WiMAX feedback header of a second type, wherein the WiMAX feedback header of the first type is transmitted every N frames, N greater than or equal to Nl (Nl > 1), and wherein the WiMAX feedback header of the second type is transmitted every Nl frame.
9. The method of claim 7, wherein the feedback headers include a feedback header of a first type and a feedback header of a second type, the feedback header of the first type containing: information identifying M best bands for transmitting data from the second wireless node to the first wireless node, where M is greater than one, channel quality indicators for the M best bands, and rank information for the M best bands
10. The method of claim 7, wherein the feedback header of the second type contains precoding matrix index (PMI) values for the M best bands, and wherein the feedback header of the second type is communicated more frequently than the feedback header of the first type
11. The method of claim 10, wherein the feedback header of the second type further contains values indicating differential channel quality indicators for the M best bands, wherein each differential channel quality indicator represents a difference in relation to the corresponding channel quality indictor in the feedback header of the first type
12. An article comprising at least one computer-readable storage medium containing instructions that when executed cause a first wireless node to: send, to the second wireless node, feedback information regarding coding to apply to signaling to be transmitted by the second wireless node, wherein the feedback information is sent in a feedback header under a first condition, the feedback header being provided with a data frame, and wherein the feedback information is sent in a control channel under a second condition
13. The article of claim 12, wherein the feedback header is of a first type, and wherein the instructions upon execution causing the first wireless node to further send: a feedback header of a second type to the second wireless node, wherein the feedback header of the first type is sent at the same frequency or more frequently than the feedback header of the second type
14. The article of claim 13, wherein the control channel is a channel quality indicator control channel (CQICH)
15. The article of claim 12, wherein the feedback information is sent in the feedback header in response to a first indication from the second wireless node, and wherein the feedback information is sent in the control channel in response to a second indication from the second wireless node
16. The article of claim 12, wherein the feedback information includes at least one precoding matrix index
17. The article of claim 16, wherein the feedback information further includes rank information and at least one channel quality indicator
18. The article of claim 16, wherein the feedback information includes multiple precoding matrix indices for respective bands of a wireless channel between the first wireless node and the second wireless node
19. The article of claim 18, wherein each of the bands includes a set of sub-carriers of different frequencies and a set of time slots.
20. A base station, comprising: a wireless interface to communicate over a wireless channel with a mobile station; a processor to: receive, over the wireless channel, a feedback data structure containing indicators identifying codings to be applied on signaling communicated between the base station and the mobile station, wherein the indicators in the feedback data structure are based on wireless channel conditions detected at the mobile station, and wherein the indicators correspond to plural bands in the wireless channel.
21. The base station of claim 20, wherein the plural bands comprise WiMAX (Worldwide Interoperability for Microwave Access) bands.
22. A mobile station, comprising: a wireless interface to communicate over a wireless channel with a base station; a processor to: send, over the wireless channel, a feedback data structure containing indicators identifying codings to be applied on signaling communicated between the base station and the mobile station, wherein the indicators in the feedback data structure are based on wireless channel conditions detected at the mobile station, and wherein the indicators correspond to plural bands in the wireless channel.
23. The mobile station of claim 22, wherein the plural bands comprise WiMAX (Worldwide Interoperability for Microwave Access) bands.']
