<p>Methods for a position reference signal (PRS) transmission, data transmission and data reception are disclosed in the present invention. When a PRS and the data borne on a physical downlink control channel (PDCCH) need to be transmitted on a same physical resources, only the data borne on the PDCCH or the PRS is transmitted on the same physical resources; or, when the PRS and the data borne on the PDCCH are transmitted simultaneously on the same physical resources by a transmission end, the reception for the PRS or the data borne on the PDCCH is ignored by the reception end; or the transmission for the PRS or the data borne on the PDCCH is restricted so that the PRS and the data borne on a PDCCH are not transmitted on the same physical resources. Devices for a position reference signal (PRS) transmission, data transmission and data reception are disclosed accordingly in the present invention. The present invention solves the problem that the data borne on a PDCCH is in conflict with the PRS on the fourth OFDM symbol when the PDCCH is transmitted on the first four OFDM symbol in a sub-frame, and ensures the overall performance of a system.</p> |
