Patent ID: 8531958

Claim:
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, wherein the indicators correspond to plural bands in the wireless channel, and wherein communicating the feedback data structure comprises communicating WiMAX (Worldwide Interoperability for Microwave Access) feedback headers, 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 NI (NI>1), and wherein the WiMAX feedback header of the second type is transmitted every NI frame.
