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.
