Patent ID: 8761116

Claim:
A method for transmitting a position reference signal, the method comprising: frequency domain positions for transmitting a position reference signal being n physical resource blocks, and the value of n being obtained according to signaling; time domain positions for transmitting the position reference signal being a remaining orthogonal frequency division multiplexing symbols in a subframe except for orthogonal frequency division multiplexing symbols for transmitting a physical downlink control channel and orthogonal frequency division multiplexing symbols for transmitting a cell-specific reference signal; and the position reference signal being transmitted according to the frequency domain position and the time domain position, wherein the physical resource blocks are n physical resource blocks which are discrete at equal intervals or n contiguous physical resource blocks; wherein the n physical resource blocks which are discrete at equal intervals are numbered with r, r+k, r+2×k, . . . , r+(n−1)×k respectively, wherein r represents the starting position of the n physical resource blocks which are discrete at equal intervals, and k represents an interval between two adjacent physical resource blocks; wherein the n contiguous physical resource blocks is n contiguous physical resource blocks starting from a low frequency, or n contiguous physical resource blocks with zero frequency as their center, or n contiguous physical resource blocks with high frequency as a cut-off, or n contiguous physical resource blocks obtained according to a notification of the signaling.
