Abstract
An evolving-type resource structure supports high data rate services at high mobile speeds. The evolving-type resource structure is an efficient diversity-exploiting user resource structure for fast time-varying frequency-selective fading channel environments. In one example, an evolving-type resource structure takes advantages of both band-type and interleaved-type structures which exploit both multiuser diversity and frequency diversity in fast time-varying channels. The evolving-type resource structure is applicable to centralized, semi-distributed and distributed access schemes and may be used in both downlink (DL) and uplink (UL) transmissions in a cellular system.
