METHOD FOR ACQUIRING INFORMATION IN A COEXISTENCE SYSTEM, AND APPARATUS USING SAME

摘要

Provided is a method for reducing signaling and computation overhead which accompany optimum operating channel allocation. To this end, a method for receiving a measurement report according to one embodiment of the present invention comprises: a step in which an apparatus including a coexistence manager (CM) transmits, to a coexistence enabler (CE), a measurement request message for acquiring a measurement report from at least one device that uses a channel in a TV band; and a step in which the apparatus receives, from the coexistence enabler, a measurement response message containing the result of the measurement. The measurement request message includes a first element, wherein the first element indicates whether a primary detection, a detection of the device that uses the TV band (TVBD), and a channel load measurement is required. The measurement request message further includes a start frequency, an end frequency, a channel list, and/or a measurement time related to the measurement. The measurement report includes the result of the primary detection, the result of the detection of the device that uses the TV band (TVBD), and/or the result of the channel load measurement.
