Title:
無線通信ネットワークにおいてアンテナ選択信号を生成する方法およびシステム
Document Type and Number:
Japanese Patent JP2010510692
Kind Code:
A
Abstract:
A method and system generating signal to select a subset of antennas from a set of antennas to transmit user data in a wireless communication system. User data are transmitted during a first transmission time intervals (TTI) using a first subset of antennas. Pilot tones are transmitted during a second TTI using a second subset of antennas. Corresponding channels are estimated for the first subset of antennas and the second subset of antennas from the user data and the pilot tones. Then, based on the estimating, an optimal subset of antenna is selected from the first subset of antennas and the second subset of antennas to transmit the user data during a sequent TTI, and in which the selecting is performed adaptively.
