Abstract
A method of transmitting a signal from a base station to a user equipment in a multi-node system comprises down-link-transmitting a signal at a first zone of a radio frame by using centralized antennas (CAs); and downlink-transmitting a signal at a second zone used for a backhaul link of a relay in the radio frame by using distributed nodes, wherein the first zone and the second zone are multiplexed by time division.
Claims11
A method of transmitting a signal to a user equipment in a wireless communication system supporting distributed antenna system (DAS), the method performed by a base station and comprising:
- transmitting a first signal through a first zone of a radio frame using centralized antennas (CAs);
- transmitting a second signal through a second zone used for a backhaul link of a relay station in the radio frame using distributed antennas (DAs);
- and
- broadcasting system information through the first zone, wherein the system information indicates that the wireless communication system can use the relay station and perform communication at the second zone using the DAS instead of the relay station,
- wherein the first zone and the second zone are multiplexed by time division.
A method of receiving a signal from a base station in a wireless communication system supporting a distributed antenna system (DAS), the method performed by a user equipment and comprising:
- receiving a first signal through a first zone of a radio frame using centralized antennas (CAs);
- receiving a second signal through a second zone used for a backhaul link of a relay station in the radio frame using distributed antennas (DAs);
- and
- receiving system information through the first zone, wherein the system information indicates that the wireless communication system can use the relay station and perform communication at the second zone using the DAS instead of the relay station,
- wherein the first zone and the second zone are multiplexed by time division.
A base station for transmitting a signal in a wireless communication system supporting a distributed antenna system (DAS), the base station comprising:
- an antenna module including a plurality of centralized antennas (CAs) and a plurality of distributed antennas (DAs);
- a transmitting module for transmitting a signal;
- and
- a processor which is configured to:
- multiplex a radio frame into a first zone and a second zone used for a backhaul link of a relay station through time-division,
- transmit a first signal at the first zone through the CAs, and
- transmit a second signal at the second zone using the distributed antennas (DAs);
- and
- broadcast system information through the first zone, wherein the system information indicates that the wireless communication system can use the relay station and perform communication at the second zone using the DAS instead of the relay station.
A user equipment for receiving a signal from a base station in a wireless communication system supporting a distributed antenna system (DAS), the user equipment comprising:
- a receiving module;
- a transmitting module;
- and
- a processor which is configured to:
- receive a first signal through a first zone of a radio frame using centralized antennas (CAs);
- receive a second signal through a second zone used for a backhaul link of a relay station in the radio frame using distributed antennas (DAs);
- and
- receive system information through the first zone, wherein the system information indicates that the wireless communication system can use the relay station and perform communication at the second zone using the DAS instead of the relay station,
- wherein the first zone and the second zone are multiplexed by time division.
