Abstract

This paper proposes an efficient bandwidth request method for a non-real-time polling service and best effort service in the IEEE 802.16 system. The proposed method produces a bandwidth request code to indicate the channel quality and the necessary number of slots. The base station allocates uplink bandwidth depending on the bandwidth request code. Thus, the proposed method can omit the transmission procedure of the bandwidth request message. The performance analysis results show that the proposed method can reduce the delay for the uplink data transmission.
