Abstract
A scheduling method in a wireless communication system using a relay station is provided. The method includes receiving scheduling information from the relay station, and performing scheduling by using the scheduling information, wherein a scheduling metric is determined for each mobile station or each connection when the scheduling is performed. Accordingly, scheduling can be effectively performed since a base station can recognize a state of a relay station.
Claims11
A scheduling method in a wireless communication system using a relay station, the method comprising:
- receiving scheduling information from the relay station;
- and
- performing scheduling by using the scheduling information,
- wherein a scheduling metric is determined for each connection between the relay station and a mobile station when the scheduling is performed, and
- wherein the scheduling information comprises:
- a downlink buffer size for each connection between the relay station and the mobile station, a channel state for each connection between the relay station and the mobile station, a downlink buffer depletion time for each connection between the relay station and the mobile station, a downlink buffer decrement rate for each connection between the relay station and the mobile station, and an urgency level indicating a degree of urgency of scheduling for downlink transmission for each connection between the relay station and the mobile station.
A scheduling information transmission method of a relay station in a wireless communication system, the method comprising:
- configuring scheduling information for a downlink transmission;
- and
- transmitting the scheduling information to a base station,
- wherein the scheduling information comprises a communication state between the relay station and a mobile station,
- wherein the communication state is indicated by an urgency level expressed in a bit-stream format to indicate a degree of urgency of scheduling for the downlink transmission for each connection between the relay station and the mobile station, and
- wherein:
- the urgency level is expressed with one bit,
- if the one bit is “1”, then the downlink transmission is more frequently performed, and
- if the one bit is “0”, then the downlink transmission is less frequently performed.
