METHOD AND DEVICE FOR TRANSMITTING/RECEIVING POSITIONING REFERENCE SIGNAL IN HETEROGENEOUS COMMUNICATION SYSTEM

摘要

The present invention relates to a method and a device for transmitting/receiving a positioning reference signal (PRS) in a wireless communication system, in particular, a heterogeneous communication system. In the heterogeneous communication system having one or more macrocells and one or more non-macrocells located inside each of the macrocells, the non-macrocells or the macrocells transmit the PRS by forming and transmitting respective PRS patterns in a time-frequency resource space area that does not duplicate a time-frequency resource space where corresponding macrocells or corresponding non-macrocells transmit the PRS. The present invention can be used to minimize the influence of interference between base stations of different forms in the heterogeneous communication environment, and promote enhancement of accuracy in measuring the position of a user equipment.
