具体实施方式
如前所述，目前3GPP下行系统采用CP-OFDM波形，即下行数据及参考信号是频域信号，其中用于CSI干扰测量的参考信号信息是频域参考信号，且数据需对进行速率匹配。具体而言，3GPP可以支持两种图案(pattern)。
参照图1，图1是现有技术中一种参考信号信息占据的RE的位置的示意图。
具体地，pattern1可以采用连续两个OFDM符号，每个符号占用的RE是一样的，且每个符号占用单个资源块(Resource block)的两个连续的RE(Resource element)；pattern2可以只占用1个OFDM符号，其占用单个资源块(Resource block)的4个连续的RE；且对于这两种pattern，其可以占用1个slot内14个OFDM符号中的任意1个符号。
如图1所示，pattern1可以占据第3个和第4个OFDM符号，且在每个OFDM符号上单个资源块(Resource block)占据第1个和第2个RE；pattern2可以占据第9个OFDM符号，在第9个OFDM符号上单个资源块(Resource block)占据第1个至第4个RE。对于这两种pattern，在每个资源块的RE位置是一样的。
本发明的发明人经过研究发现，在现有技术中，对于下行采用单载波波形的系统，如卫星系统，高频系统，目前尚未设计参考信号信息用于CSI的干扰测量，亟需一种参考信号信息的确定方法，填补这方面的空白。
在本发明实施例中，接收网络配置信息，所述网络配置信息至少包括参考信号信息的OFDM符号位置；根据所述参考信号信息的OFDM符号位置，确定所述参考信号信息。采用上述方案，根据所述参考信号信息的OFDM符号位置，确定所述参考信号信息，可以在采用单载波波形的系统中，实现对所述参考信号信息的确定。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
