Claim:
1. A signal transmission method, comprising: acquiring, by a UE, resource position information, used for indicating the UE to transmit identification signal of the UE, from a network side; and determining, by the UE, a specific resource for transmitting the identification signal according to the resource position information, and transmitting the identification signal of the UE on the specific resource; wherein the method further comprises: acquiring, by the UE, parameter information used for indicating the UE to transmit the identification signal from the network side; wherein the transmitting, by the UE, the identification signal of the UE on the specific resource comprises: transmitting, by the UE, the identification signal of the UE on the specific resource according to the parameter information; wherein transmitting, by the UE, the identification signal of the UE on the specific resource according to the parameter information comprises: monitoring, by the UE, N consecutive identification signal sub-frames, wherein the N consecutive identification signal sub-frames are next N consecutive identification signal sub-frames beginning from the time of needing to transmit the identification signal, and N is a positive integer; and randomly selecting, by the UE, an identification signal resource to transmit its own identification signal if the N consecutive identification signal sub-frames are free; and/or selecting, by the UE, a resource to transmit its own identification signal according to an indication of the resource position information, beginning from time of needing to transmit the identification signal; and repeatedly transmitting, by the UE, the identification signal for N times in a specific time according to repetition parameters transmitted by the network side, after transmitting the identification signal for the first time, wherein the specific time and N are the repetition parameters.
