Method for transmitting a signal for a location-based service in a wireless communication system, and apparatus for same

摘要

The present invention relates to a wireless communication system. Particularly, in configuring a location estimation subframe for determining the location of a terminal in a wireless communication system, the present invention involves replacing a portion of repeating patterns of a channel estimation pilot in the location estimation subframe with a location estimation pilot. In this way, the present invention is capable of transmitting a location estimation reference signal for a location-based service to the terminal while minimizing influences on an existing wireless frame structure.

主权项

1. A method for transmitting, by a base station, a location measurement pilot for location based services in a wireless communication system, the method comprising:
transmitting a channel estimation pilot according to a predefined pilot pattern for the channel estimation pilot in a subframe other than a location measurement subframe configured for transmission of the location measurement pilot, and transmitting the location measurement pilot and the channel estimation pilot in the location measurement subframe; and wherein the location measurement pilot is transmitted instead of the channel estimation pilot at a part of the predefined pilot pattern on at least one frequency resource unit in the location measurement subframe, and wherein the location measurement subframe is other than a subframe with a superframe header which is transmitted at a first subframe of each superframe which includes four frames each of which includes a plurality of subframes.
