METHOD AND EQUIPMENT FOR MULTIPLE-INPUT MULTIPLE-OUTPUT (MIMO) CHANNELS INFORMATION FEEDBACK IN MULTIPLE CELLS |
摘要 |
<p>A mobile terminal is provided in the present invention, comprising: a channel state information feedback calculating unit configured to calculate a channel state information feedback between the mobile terminal and a serving cell of the mobile terminal and those between the mobile terminal and all cooperating cells; a channel quality information feedback calculating unit configured to calculate a channel quality information feedback for the serving cell of the mobile terminal; and a transmission unit configured to transmit the channel state information feedbacks and the channel quality information feedback to the serving cell. The present invention greatly improves the performance of a LTE-A system and greatly reduces feedback overhead. The present invention is a scalable feedback solution and may be flexibly applied to various coordinated multipoint transmission scenarios.</p> |
