Title:
無線通信された信号に適用される符号化を特定する情報を含むフィードバックデータ構造の通信
Document Type and Number:
Japanese Patent JP5433589
Kind Code:
B2
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.
