Method and apparatus for adjusting signal transmission starting point of terminal in wireless network

摘要

Disclosed is a method for adjusting a transmission time point of at least one second terminal in a wireless network by a first terminal. In the method for adjusting a transmission time point of a terminal, a transmission time point of the second terminal is set, a first frame including information regarding the transmission time point is transmitted to the second terminal, a first response frame transmitted according to the transmission time point from the second terminal is received, and the transmission time point is adjusted according to an arrival time of the first response frame.

主权项

1. A first terminal performing cooperative communicate with a relay and a second terminal comprising:
a processor configured to: transmit a first request frame to the relay; transmit a second request frame to the second terminal; receive a first response frame from the relay at first time corresponding to the first request frame; receive a second response frame from the second terminal at second time different from the first time corresponding to the second request frame; adjust transmitting time point of the relay using a time difference between an estimated arrival time and an actual arrival time for the first response frame and the second response frame; and retransmit the first request frame to the relay based on the adjusted transmitting time point.
