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.

2. The method of claim 1, wherein said determining also includes:
estimating a channel matrix H of a wireless channel from the second wireless node to the first wireless node; and
determining the feedback data based at least in part on the channel matrix H.
3. The method of claim 1, wherein said selecting is based on a maximization of an objective value over at least a portion of the codebook.
4. The method of claim 1, wherein the feedback data identifies a recommended coding for signaling to be transmitted from the second wireless node to the first wireless node.
5. The method of claim 1, wherein the feedback data is transmitted over the wireless channel in a plurality of messages.
6. The method of claim 1, wherein, for each of the preferred subbands, the feedback data also includes a corresponding subband PMI.
7. The method of claim 1, wherein the second wireless node is configured to precode a transmission to the first wireless node based on at least the first PMI value.
8. The method of claim 1, wherein the feedback data is transmitted over the wireless channel in a plurality of messages, wherein a first of the messages includes a first rank value, wherein the first rank value corresponds to the column of the selected codebook entry, wherein a second of the messages includes the first PMI value.
9. A first wireless node for operating as part of a closed loop multiple-input multiple-output (MIMO) communication system including the first wireless node and a second wireless node, the first wireless node comprising:
an antenna system; and
circuitry coupled to the antenna system and configured to:
determine feedback data, wherein determining feedback data includes selecting an entry in a predefined codebook, wherein rows of the codebook correspond respectively to two or more values of PMI, wherein columns of the codebook correspond respectively to two or more rank values;
