Title:

マルチユーザ多入力多出力（ＭＵ−ＭＩＭＯ）のためのチャネル状態情報（ＣＳＩ）フィードバック・プロトコル

Document Type and Number:

Japanese Patent JP5607248

Kind Code:

B2

Abstract:

Certain aspects of the present disclosure provide techniques and apparatus for using channel state information (CSI) feedback for multiuser multiple-input multiple-output (MU-MIMO) transmission. For certain aspects, a method of wireless communications generally includes generating a training frame and transmitting the generated training frame. The training frame typically includes first information identifying a group of one or more apparatuses and second information indicating whether each of the apparatuses in the group is to determine at least one characteristic of a channel. For other aspects, a method of wireless communications generally includes receiving a request at an apparatus and transmitting, in response to the received request, a packet using frame aggregation, wherein two or more frames are transmitted in a single transmission using a single header.
