    The conventional cellular architecture will remain an integral part of nextgeneration wireless systems, providing high-speed packet data services directly to mobile users and also backhaul service for local area networks. In this paper, we present several proposals addressing the challenges associated with the critical design issues for the next-generation cellular wireless physical layer. These proposals include an orthogonal frequency division multiplexed (OFDM) or multicarrier code division multiple access (MC-CDMA) air interface for wide channel bandwidths, considerations for resource allocation, multiple antenna techniques, a hybrid duplexing technique combining the benefits of time division and frequency division duplexing, and coordinated networks for reducing intercell interference and increasing overall spectral efficiency.
