17 PAPR requirements of OFDMA forced the standard to use Single Carrier Frequency Division Multiple Access (SC-FDMA) for the uplink in order to conserve battery life on the mobile devices. OFDMA was also proposed for digital video broadcasting return channel terrestrial and several other broadband wireless standards, such as the IEEE 802.16 standard. OFDMA’s flexibility in allocating resources (such as subcarriers, power and modulation schemes) to users can be attributed to the resource allocation algorithms employed by the OFDMA system. Resource allocation in OFDMA systems is discussed in detail in section 4.0. Since resource allocation is of considerable importance in OFDMA systems, basics of radio resource allocation have been presented in section 3.0. Section 3.0 intends to help the readers of this report build some background on radio resource allocation, before they move onto reading the section on resource allocation in OFDMA systems. 3.0 BASICS OF RADIO RESOURCE ALLOCATION
