一种数据发送方法及装置制造方法及图纸

一种数据发送方法及装置，所述方法用于多载波通信系统中，该通信系统包括第一成员载波和第二成员载波，其中第一成员载波既用于终端的下行传输又用于该终端的上行传输，第二成员载波为用于该终端的下行传输的单下行成员载波，包括：第一基站确定第一成员载波在第二成员载波使用的天线上的天线权值，其中第一基站为第二成员载波所在的基站；当第一成员载波和该第二成员载波的信道相似度满足预设要求时，利用该天线权值对第二成员载波上的该终端的下行数据进行加权；向该终端发送加权的下行数据，这样，能够提高多载波场景中终端的解调信噪比和吞吐量。

A Data Transmission Method and Device

A data transmission method and device for a multi-carrier communication system comprising a first member carrier and a second member carrier, in which the first member carrier is used for both downlink transmission of the terminal and upstream transmission of the terminal, and the second member carrier is a single downlink member carrier for downlink transmission of the terminal, including: the first base station determines the first 10%. The antenna weight of the member carrier on the antenna used by the second member carrier, in which the first base station is the base station where the second member carrier is located; when the channel similarity of the first member carrier and the second member carrier meets the preset requirements, the antenna weight is used to weigh the downlink data of the terminal on the second member carrier; and the weighted downlink data is transmitted to the terminal, thus, It can improve the demodulation signal-to-noise ratio and throughput of terminals in multi-carrier scenarios.
