%X In this paper, we begin with some existing technologies improving capability of BWA system, analyzing some resolvents of overcoming communication defects, and finally summarize that the key of improving the capacity of BWA system is to enhance the utilization ratio of existing bandwidth and the tolerance to the frame error of wireless channel. And then, we adopt the resolvents that centralized and dynamic allocation strategy in uplink to enhance the utilization ratio of bandwidth, and MR-ARQ and multi-rate retransmission strategy to enhance the tolerance to SNR.
