A QoS parameter calculating unit(306) calculates a parameter for satisfying a current radio resource efficiency and QoS requirements of each user terminal path reflecting whether to re-use resources. A scheduling priority index calculating unit(304) calculates a scheduling priority index of each user terminal by using the current radio resource efficiency and the QoS parameter.

Abstract: An apparatus and a method for selecting a relay mode in a broadband wireless communication system using multi-hop relay are provided to improve a production yield and an outage performance of a system by using a proper relay mode according to a terminal distribution or a channel state. A base station requests channel state information with relay stations from a terminal(501), and checks whether a signal is received from the terminal(503). The base station checks channel state information between the relay stations and the terminal included in a reception signal(505). The base station estimates an interference strength and a signal strength by using the channel state information(507). The base station estimates CINRs(Carrier to Interference and Noise Ratios) of a simple relay mode and a cooperative relay mode(509), and determines a relay mode to provide a relay service by using the CINRs(511). The base station transmits resource allocation information including the relay mode to the relay stations and the terminal(513), and transmits data to the relay stations or the terminal according to the resource allocation information(515).

Abstract: A device for allocating resources to relay stations in a relay-type wireless communication system and a method therefore are provided to determine resource reuse patterns by using interference information measured in each relay station, thereby enabling efficient resource operation even when the relay stations are irregularly disposed. N relay stations measure mutual interference by exchanging beacon signals with other relay stations within a cell, and feed back the measured interference information to base stations. The base stations allocate resources for the N relay stations, so that the N relay stations reuse the resources by using the interference information fed back from each of the N relay stations. When at least one of the relay stations transmits the beacon signals by using uplink sounding channels, the rest of the relay stations receive the beacon signals.

The BS receives an uplink burst from the terminal 1 during the first section of the uplink sub frame. The BS receives the uplink burst from the RS during the second section. The RS transmits a preamble, control information, and a downlink burst successively to a terminal 2 connected by a relay link during the first section of the downlink sub frame. The RS receives control information, a downlink burst, and a post preamble from the BS during the second section successively. The RS receives the uplink burst from the terminal 2 during the first section of the uplink sub frame. The RS transmits the uplink burst received from the terminal 2 during the first section to the BS during the second section. An R-TTG(Relay TTG)(335) of a time protection area exists between the first section and second section of the downlink sub frame.

Abstract: An apparatus and a method for distributing radio resources in a multi-hop relay broadband wireless access communication system are provided to increase the transmission efficiency without a waste of resources of an overall system by evenly distributing radio resources to relay stations that re-use frequency resources by using two types of schedulers. A priority level of each transmission packet is determined so that channels can be evenly allocated to relay stations that use the same radio resources by using an inter-scheduling and intra-scheduling. The number of sub-channels required for transmitting packets is determined according to each priority level, and a temporary frame is generated to determine the number of sub-channels to be allocated to the relay stations that use the same radio resources. Packets included in the generated temporary frame are divided by link and allocated by sub-channel.
