Abstract
Official abstract text for this publication.
Disclosed is a technique related to a method for controlling synchronization by correcting data transmission time or frequency offset, and to a station. According to the technique, a method for controlling the synchronization of a first terminal for data transmission/reception in a coordinated communication system comprises: a step of transmitting a first request frame and a second request frame containing transmission time information for each of a first response frame and a second response frame to a second terminal and to a third terminal, respectively; a step of receiving the first response frame and the second response frame from the second terminal and the third terminal; a step of estimating a first propagation delay time between the first terminal and the second terminal and a second propagation delay time between the first terminal and the third terminal, using the time of receiving the first response frame and the second response frame; and a step of transmitting, to the second terminal, a third request frame containing information on the delay time difference between the first propagation delay time and the second propagation delay time.
First claim
Opening claim text (preview).
The invention claimed is: 1. A synchronization control method of a first terminal for transmission and reception of data in a cooperative communication system, the synchronization control method comprising: transmitting, to a second terminal and a third terminal, a first request frame and a second request frame that include information regarding points in time when a first response frame and a second response frame are to be transmitted by the second terminal and the third termina…
