摘要： The present invention discloses methods for sending positioning reference signals (PRSs), for sending data and for receiving data. When PRSs and data carried by a physical downlink control channel (PDCCH) are required to be sent on a same physical resource, only the data carried by the PDCCH or the PRSs are sent on the same physical resource; or, when a sending end sends the PRSs and the data carried by the PDCCH on the same physical resource at the same time, a receiving end is made to ignore the received PRSs or the data carried by the PDCCH; or, the sending of the PRSs or the data carried by the PDCCH is limited so that they will not be sent on the same physical resource. The present invention also discloses devices for sending positioning reference signals, for sending data and receiving data. The present invention has solved the problem that the data carried by the PDCCH are in conflict with the PRSs over the fourth OFDM symbol when the PDCCH is sent over the first four OFDM symbols in the subframe, thereby ensuring the overall performance of the system.
摘要翻译：本发明公开了用于发送定位参考信号（PRS）的方法，用于发送数据和接收数据。当物理下行链路控制信道（PDCCH）携带的PRS和数据需要在相同的物理资源上发送时，只有在同一物理资源上才发送由PDCCH或PRS携带的数据; 或者当发送端同时在同一物理资源上发送该PRS和该PDCCH所携带的数据时，使接收端忽略接收到的PRS或PDCCH携带的数据; 或者，PRS的发送或PDCCH所携带的数据被限制，使得它们不会被发送在相同的物理资源上。本发明还公开了用于发送定位参考信号的装置，用于发送数据和接收数据。本发明解决了当通过子帧中的前四个OFDM符号发送PDCCH时，PDCCH携带的数据与第四个OFDM符号上的PRS冲突的问题，从而确保了系统的整体性能。
