“…A fundamentally different spectrum reuse scheme is required for more efficient packet data transmission. Studies [1], [9] showed that for high-capacity packet-switched networks, it is preferable to have all cells share the entire spectral resources, i.e., .

Fueled by the explosive growth of the Internet, applications are demanding higher data rates and better services. Given the scarcity of radio resources, higher network capacities need to be achieved through more efficient use of the available bandwidth. Current cellular networks utilize frequency planning schemes that are optimized for circuit-switched applications, and thus is inherently problematic for future wireless packet networks with bursty, high peak-rate traffics. Random access schemes such as the ALOHA are seen as better solutions for packet networks. However, co-channel interference may significantly reduce the network throughput when the multicell load is heavy.In this paper, we propose a distributed rate adaptive packet access (DRAPA) scheme to combine the advantages of rate adaptation (in circuit-switched networks) and random access (in packet-switched networks). In particular, DRAPA allows terminal stations to transmit packets in random access fashion in the presence of brusty interference from neighboring cells. The packet code rate is adjusted according to interference level so that the retransmisson is controlled at an acceptable level. The DRAPA scheme subsumes two traditional schemes as the extreme cases, and has superior performance over the traditional schemes in terms of throughput and stability.

“…For bursty users that send short packets to a satellite transponder, spread Aloha (see the arti- cle by Abramson in this issue) has been proposed as a spread spectrum variant of the classical random access protocol in which all users employ a common spreading sequence. Following the trend in cellular telephony, the benefits of increased frequency reuse will be realized in wireless packet-switched random access communication [10] as soon as effective methods to combat bursty multi-user interference become a reality. An intriguing alternative which may eventually become practical, and even legal, for short-range communication between static terminals is ultrawideband impulse radio [11].…”
