Embodiment approach 1

[0084] refer to figure 1 , the radio communication system according to Embodiment 1 in which radio signals are relayed using the Relay technology will be described. figure 1 It is a diagram showing the configuration of the wireless communication system according to the first embodiment. In the wireless communication system according to Embodiment 1, a wireless communication relay station device (hereinafter referred to as a relay station) 300 is installed between a base station 100 and a wireless communication terminal device (User Equipment: UE, hereinafter referred to as a terminal) 500, and Communication between the base station 100 and the terminal 500 is performed. If the relay technology is used, the terminal 500 that cannot directly communicate with the base station 100 can also communicate via the relay station 300 .

[0085] In addition, the relay of the wireless communication system according to the present embodiment is a time division relay (TD relay), and its ...

Abstract

The placement of unused REGs is changed, thereby effectively using the transmission power. A wireless communication apparatus, which performs a wireless communication with a terminal apparatus via a relay station, comprises: an allocation unit that is operative to allocate a CCE to a plurality of REGs in such a manner that unused REGs to which the CCE, in which a control signal used for the relay station is placed, cannot be allocated are different between resource blocks having the plurality of REGs; and a transmission unit that is operative to transmit, based on the allocation performed by the allocation unit, the control signal, which is placed in the CCE allocated to the REGs, to the relay station.

Description

technical field [0001] The invention relates to a wireless communication device and a wireless communication method. Background technique [0002] In recent years, in the cellular mobile communication system, the transmission of not only voice data but also large-capacity data such as still image data and moving image data has become popular along with the multimediaization of information. In order to realize the transmission of large-capacity data, active research is being conducted on a technique for realizing a high transmission rate using a high-frequency wireless band. [0003] However, in the case of using a high-frequency wireless band, a high transmission rate can be expected at a short distance, but on the other hand, as the distance increases, the attenuation due to the transmission distance also increases. Therefore, when a mobile communication system using a high-frequency radio frequency band is actually used, the coverage area of ​​a radio communication base s...
