Title (EN) HYBRID CHANNEL STATE INFORMATION FEEDBACK METHOD, TERMINAL DEVICE AND BASE STATION
(FR) PROCÉDÉ DE RETOUR D'INFORMATIONS D'ÉTAT DE CANAL HYBRIDES, DISPOSITIF TERMINAL ET STATION DE BASE
(ZH) 一种混合信道状态信息反馈的方法、终端设备及基站
Abstract:
(EN) The embodiments of the present invention relate to a hybrid channel state information feedback method, a terminal device and a base station. The method comprises a terminal device reporting channel state information (CSI) to a base station, the CSI being reported in two stages, first stage reporting being based on the CSI when the number of beam forming channel state information reference signal (CSI-RS) resources is greater than 1, second stage reporting being based on the CSI when the number of beam forming CSI-RS resources is equal to 1, and the CSI reporting of the two stages occupying one CSI reporting process. In the embodiments of the present invention, by means of the hybrid CSI feedback method provided in the embodiments of the present invention, the reporting of hybrid CSI based on beam forming CSI-RS is realized, the overhead of the CSI reporting can be reduced, the accuracy of the CSI reporting is improved, and thus the cell throughput can be improved.
(FR) Les modes de réalisation de la présente invention concernent un procédé de retour d'informations d'état de canal hybrides, un dispositif terminal et une station de base. Au cours du procédé, un dispositif terminal rapporte des informations d'état de canal (CSI) à une station de base. Les CSI sont rapportées selon deux étages. Un rapport de premier étage est basé sur les CSI lorsque le nombre de ressources de signal de référence d'informations d'état de canal (CSI-RS) de formation de faisceau est supérieur à 1. Un rapport de second étage est basé sur les CSI lorsque le nombre de ressources de CSI-RS de formation de faisceau est égal à 1. Le rapport de CSI à deux étages couvre l'ensemble d'un processus de rapport de CSI. Le procédé de retour de CSI hybrides d'après les modes de réalisation de la présente invention permet d'effectuer le rapport de CSI hybrides sur la base d'un CSI-RS de formation de faisceau, de réduire le surdébit du rapport de CSI, d'accroître la précision du rapport de CSI et par conséquent d'améliorer le débit cellulaire.
(ZH) 本发明实施例涉及一种混合信道状态信息反馈的方法、终端设备及基站,该方法包括终端设备向基站上报信道状态信息CSI,所述CSI分两级进行上报,第一级上报基于波束赋形信道状态信息参考信号CSI-RS资源数大于1时的CSI,第二级上报基于波束赋形CSI-RS资源数等于1时的CSI,所述两级CSI上报占用一个CSI上报进程。本发明实施例提供的混合CSI反馈的方法,实现基于波束赋形CSI-RS的混合CSI的上报,可降低CSI上报开销,提高CSI上报精确性,进而可提高小区吞吐量。
