Abstract: A base station (101) will instruct relay stations (102) to periodically skip transmissions of their control information when control messaging by all relay stations exceeds a predetermined threshold (e.g., 50% of radio resource capacity). The base station determines the relay stations to skip by periodically ranking the relay stations and skipping control messages for relay stations having a lowest rank.

Abstract translation: 当所有中继站的控制消息传送超过预定阈值（例如，无线资源容量的50％）时，基站（101）将指示中继站（102）周期性地跳过其控制信息的传输。 基站通过周期性地对中继站进行排序来确定要跳过的中继站，并且跳过具有最低等级的中继站的控制消息。

Abstract: At least one operating condition is determined for a first mobile subscriber station (104) that is operating in an orthogonal frequency division multiple access (OFDMA) network. The first mobile subscriber station (104) is handed off from a base station (102) to a relay station (110). Based upon the at least one operating condition, at least one sub-channel is subsequently assigned from a plurality of sub-channels of a frequency band to the first mobile subscriber station (104) in order to provide an assigned sub-channel resource to the first mobile subscriber station (104). The assigned sub-channel resource can potentially be any of the plurality of sub-channels of the frequency band.

Abstract: A method and apparatus for relaying data within a multi-hop communication system (200) is provided herein. During operation, all preamble (301, 305) and broadcast (303, 307) information for relaying nodes (201) and for the base station (204) is placed during a beginning portion (315) of a frame (300) prior to any data transmission (511, 609). By placing preamble/broadcast portions in the beginning of the frame, the data transmission portions of the frame can be allowed to vary in time, yet synchronization will be allowed between all nodes in the system.
