Frequency band allocation method and transmission device

摘要

Disclosed is a frequency band allocation method which reduces PAPR (peak to average power ratio) when performing a single carrier transmission in the uplink line of an LTE+ (LTE Advanced) system in a system using both of an LTE (Long Term Evolution) system and the LTE+ system. In the frequency band allocation method, a UL band for the LTE is arranged adjacently in a lower frequency band than the UL band for the LTE+. With this arrangement, it is possible to prevent division of the band for the LTE+ by the uplink line control channel (such as PUCCH) transmitted by an LTE mobile station and to allocate a wide band continuously with the LTE+ mobile station. Especially when the LTE+ mobile station performs a single carrier transmission with the uplink line, the PAPR can be reduced since it is possible to allocate a band continuous with the single carrier signal.
