Abstract

本发明提出了一种天线相关上行反馈方法，包括：基站向用户设备通知针对指定的天线进行指定形式的上行信息反馈；用户设备针对所述指定的天线向基站进行所述指定形式的上行信息反馈。根据本发明，基站可以通过调度，减少携带较少信息量的天线反馈信息的发送次数和/或所占用资源，增加携带较多信息量的天线反馈信息的发送次数和/或所占用资源；有效地节省了上行反馈开销，同时可以确保性能的损失在可接受的范围以内。另外，考虑到和3GPP LTE Release 8系统的兼容性，本发明可以有效地解决3GPP LTE Release 8系统中上行反馈资源短缺的问题，所述资源包括侦听参考符号(SRS)、物理上行控制信道(PUCCH)等。
