Abstract:
1. A method of a relay node transmitting data, the method comprising: transmitting, by a Relay Node (RN) via a second time zone, an access link channel measurement reference signal to a relay node user equipment; receiving, by the RN via the second time zone, access link channel information about the access link channel measurement reference signal from the relay node user equipment; generating, by the RN via a first time zone, scheduling information about an access link based on the access link channel information; receiving, by the RN via the first time zone, a backhaul link channel measurement reference signal from a base station; transmitting, by the RN via the first time zone, backhaul link channel information, obtained by measuring the backhaul link channel measurement reference signal, and scheduling information about the access link to the base station; receiving, by the RN via the first time zone, data to be relayed to the relay node user equipment from the base station; and transmitting, by the RN via the second time zone, the data to the relay node user equipment based on the scheduling information about the access link.
