ABSTRACT
This chapter focuses on the development of scheduling and radio resource allocation that can be used for the IEEE 802.16j-based wireless relay networks. The considered cooperative diversity schemes are cooperative transmit diversity, cooperative receive diversity and cooperative selection diversity. The chapter analyses a fully adaptive cooperative diversity scheme which selects the best transmission scheme among various cooperative diversity schemes and the w/o relay scheme. For the emerging IEEE 802.16j-based wireless networks, it provides a performance evaluation of various cooperative diversity schemes in a multi-user environment. The chapter identifies the beneficial cooperative diversity scheme in terms of spectral efficiency and complexity for low mobility users. Scheduling of the users in multi-hop cellular networks needs modifications on conventional scheduling algorithms designed for the w/o relay networks. From the system-level throughput point of view, the cooperative selection diversity can perform as well as more complex cooperative diversity schemes which require coherent signal combining at the destination.
