摘要： The transmission of a reference signal, such as a CSI-RS, is enabled while maintaining a power saving effect when performing inter-cell cooperative transmission/reception or the like in a plurality of cells. In order to realize inter-cell cooperative transmission/reception, a CSI-RS which is used for estimating the state of a spatial propagation path of a communication line is generated by a CSI-RS generation unit, and the CSI-RS is disposed in a predetermined subframe by a disposition unit and transmitted. At this time, when a frame has ten subframes #0 to 49, the CSI-RS is disposed in the subframes #4 and #9, which are subframes excluding the subframes #0 and #5 incapable of transmitting a CSI-RS and are subframes other than subframes capable of acting as MBSFN subframes when discontinuous communication (Extended Cell DTX) is performed so as to achieve power saving, and transmitted.

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.

摘要： The signaling amount in selecting a plurality of beams is reduced in pre-coding to thereby enhance the throughput. To select a plurality of beams when the pre-coding is applied, when notification of a beam number is provided in a feedback signal from a user equipment 102 as a reception station to a radio base station 101 as a transmission station, a superior beam number having a high quality rank with small time variation is bound up and fixed for a predetermined time period and notification of only a inferior beam number is provided within the time period. For example, to select three beams from six beams, first, notification of the superior two beam numbers (beam numbers ‘b’ and ‘c’) is provided and the superior beam numbers are fixed for a predetermined time period and then notification of only the inferior one beam number (beam number ‘e’) is provided within the predetermined time period for reducing the signaling amount for providing beam number notification.
