Claim of US Patent No. 9,603,135

1. A method for transmitting a Position Reference Signal (PRS), comprising:
a network side configuring at least one of a Channel State Information Reference Signal (CSI-RS), a transmission Physical
Downlink Shared Channel (PDSCH) and a Relay backhaul link according to the configuration condition of a PRS, or the network
side configuring the PRS according to the configuration condition of at least one of the CSI-RS, the transmission PDSCH and
the Relay backhaul link; and

the network side transmitting to a receiving side the configuration information of the PRS and the configuration information
of at least one of the corresponding CSI-RS, the transmission PDSCH and the Relay backhaul link;

wherein the method further comprises: when a CP of the subframe 0 is configured as a Normal CP and the PRS is configured to transmit only on the MBSFN subframe by the network side, the subframe
for transmitting the PRS is not configured to transmit the PDSCH; wherein when the CP of the subframe 0 is configured as a Normal CP and the PRS is configured to transmit only on the MBSFN subframe by the network side, the receiving
side does not expect to receive the PDSCH on the subframe which transmits the PRS when receiving the channels or signals of
the network side;

wherein the network side semi-statically configures the period and subframe bias of the PRS, and notifies the relative configuration
of the PRS to the receiving side via the broadcast channel, and then the network side configures the OFDM CPs of all the PRS
subframes according to the CP configuration type of the subframe 0.
