摘要： Embodiments of the present invention disclose a transmit diversity method, a related device, and a system, which mainly includes: configuring two different antenna ports separately for different antennas in a network, so that the antennas can use transmit diversity based on the configured antenna ports. In one aspect, because two antenna ports are used in the network to perform transmit diversity, a diversity gain of multiple antennas is obtained; in another aspect, a cavity position caused by a completely identical precoding codebook used in the network is avoided, and therefore network communication performance is improved. In conclusion, the technical solutions according to the embodiments of the present invention efficiently use the transmit diversity of the multiple antennas to acquire the diversity gain, so as to improve network communication performance.

摘要翻译： 本发明实施例公开了一种发射分集方法，相关装置和系统，主要包括：为网络中的不同天线分别配置两个不同的天线端口，使得天线可以基于配置的天线端口使用发射分集 。 一方面，因为网络中使用两个天线端口来执行发射分集，所以可以获得多个天线的分集增益; 在另一方面，避免了由在网络中使用的完全相同的预编码码本导致的空腔位置，并且因此提高了网络通信性能。 综上所述，根据本发明实施例的技术方案有效利用多天线的发射分集来获取分集增益，从而提高网络通信性能。
