摘要： 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.

摘要： To perform wireless communications in a wireless network, at least two spatial beams are formed within a cell segment, where the at least two spatial beams are associated with different power levels. The at least two spatial beams are swept across the cell segment according to a sweep pattern. In some implementations, multiple antenna assemblies can be used, where each antenna assembly has plural antenna elements. A lower one of the antenna assemblies can be used to form high and lower power beams, and an upper one of the antenna assemblies can be used to communicate backhaul information, for example.
