Abstract
A method and apparatus of transmitting backhaul signals performed by a relay station in a wireless communication system is provided. A relay station performs scheduling with a base station in order to transmit the backhaul signals, and transmitting the backhaul signals to the base station using both resources for downlink transmission and resources for uplink transmission based on the scheduling.
Claims21
A method of transmitting backhaul signals performed by a relay station in a wireless communication system, the method comprising:
- receiving, from a base station, scheduling information about resources assigned to transmit backhaul signals;
- and
- transmitting the backhaul signals to the base station using both resources for downlink transmission and resources for uplink transmission simultaneously based on the scheduling information.
A method of transmitting backhaul signals performed by a base station in a wireless communication system, the method comprising:
- performing scheduling in order to transmit the backhaul signals;
- and
- transmitting the backhaul signals to at least one relay station using both resources for downlink transmission and resources for uplink transmission simultaneously based on the scheduling.
A relay station in a wireless communication system, the relay station comprising:
- a Radio Frequency (RF) unit configured to transmit and receive a radio signal;
- and
- a processor coupled to the RF unit and configured to receive from a base station, scheduling information about resources assigned to transmit backhaul signals and to transmit the backhaul signals to the base station using both resources for downlink transmission and resources for uplink transmission simultaneously based on the scheduling information.
A base station in a wireless communication system, the base station comprising:
- a Radio Frequency (RF) unit configured to transmit and receive a radio signal;
- and
- a processor coupled to the RF unit and configured to perform scheduling in order to transmit backhaul signals and to transmit the backhaul signals to at least one relay station using both resources for downlink transmission and resources for uplink transmission simultaneously based on the scheduling.
A method of receiving signals, the method performed by a wireless station and comprising:
- receiving, from a base station, a first Time Division Duplex (TDD) subframe configuration which indicates locations of at least one downlink subframe and at least one uplink subframe, wherein the first TDD subframe configuration is received at a predetermined period;
- receiving, from the base station, a second TDD subframe configuration which indicates new locations of at least one downlink subframe and at least one uplink subframe, wherein the second TDD subframe configuration is expressed as a bitmap;
- and
- after applying the second TDD subframe configuration, receiving, from the base station, the signals on a subframe,
- wherein when the second TDD subframe configuration is applied, the subframe is changed from an uplink subframe indicated by the first TDD subframe configuration to a downlink subframe, and
- wherein the subframe is configured in Multicast Broadcast Single Frequency Network (MBSFN) subframes.
A wireless station, comprising:
- a transceiver;
- and
- a processor coupled to the transceiver and configured to:
- receive, from a base station, a first Time Division Duplex (TDD) subframe configuration which indicates locations of at least one downlink subframe and at least one uplink subframe, wherein the first TDD subframe configuration is received at a predetermined period,
- receive, from the base station, a second TDD subframe configuration which indicates locations of at least one downlink subframe and at least one uplink subframe, wherein the second TDD subframe configuration is expressed as a bitmap, and
- after applying the second TDD subframe configuration, receive, from the base station, signals on a subframe,
- wherein when the second TDD subframe configuration is applied, the subframe is changed from an uplink subframe indicated by the first TDD subframe configuration to a downlink subframe, and
- wherein the subframe is configured in Multicast Broadcast Single Frequency Network (MBSFN) subframes.
