Definitions
- the channel estimation accuracy can be obtained according to the number of clusters.
- a more advantageous method of reference signal formation can be selected. By performing switching control of such a reference signal formation method, the base station 200 can obtain the channel estimation accuracy indicated by the solid line in FIG.
- each cluster is treated as one band block.
- a band block consisting of a plurality of clusters may be treated in the same manner as the clusters described in the first embodiment. That is, when there are a plurality of band blocks consisting of a plurality of clusters, by dividing one basic code sequence into a length matched to each band block, a partial sequence for the number of band blocks is formed as a reference signal A second method of forming code sequences as many as the number of band blocks may be formed as a reference signal by adjusting the length of the basic code sequence as many as the number of band blocks according to each band block.
- the reference signal control unit 106 controls the reference signal generation unit 107 to switch the reference signal formation method.
- the base station 200 can obtain the channel estimation accuracy shown by the solid line in FIG.
- the present invention has been described taking hardware as an example, but the present invention can also be realized by software.
- the method of circuit integration is not limited to LSI's, and implementation using dedicated circuitry or general purpose processors is also possible.
- a programmable field programmable gate array FPGA
- a reconfigurable processor may be used which can reconfigure connection and setting of circuit cells in the LSI.

Abstract
Description
[端末の構成]
図9は、本発明の実施の形態1に係る端末100の構成を示すブロック図である。図9において、端末100は、受信RF部101と、復調部102と、復号部103と、リソース割当情報設定部104と、閾値設定部105と、参照信号制御部106と、参照信号生成部107と、符号化部108と、変調部109と、FFT(Fast Fourier Transform)部110と、マッピング部111と、IFFT(Inverse Fast Fourier Transform)部112と、送信RF部113とを有する。
図10は、本発明の実施の形態1に係る基地局200の構成を示すブロック図である。図10において、基地局200は、受信RF部201と、DFT(Discrete Fourier transform)部202と、デマッピング部203と、リソース割当情報設定部204と、閾値設定部205と、チャネル推定制御部206と、チャネル推定部207と、周波数領域等化部208と、IFFT部209と、復調部210と、復号部211と有する。
以上の構成を有する端末100の動作について説明する。
実施の形態2では、「クラスタ帯域幅」に基づいて、参照信号の形成方法を切り替える。すなわち、参照信号の形成方法は、切替閾値及びクラスタの数nに加えてn個のクラスタの合計帯域幅に基づいて切り替えられる。なお、本実施の形態に係る端末及び基地局の基本構成は、実施の形態1で説明された端末及び基地局の構成と同じである。従って、本実施の形態に係る端末及び基地局についても、図9及び図10を用いて説明する。
実施の形態2の端末100における参照信号制御部106は、リソース割当情報設定部104からクラスタに関する情報を受け取り、まず、「クラスタ帯域幅」を算出する。この「クラスタ帯域幅」は、1クラスタ当たりの平均帯域幅を意味し、n個のクラスタの合計帯域幅をクラスタ数nで除算することにより得られる。
また、実施の形態2の基地局200におけるチャネル推定制御部206は、チャネル推定部207におけるチャネル推定方法を、端末100の参照信号送信方法に応じたチャネル推定方法に切り替える。すなわち、チャネル推定制御部206は、リソース割当情報設定部204からクラスタに関する情報を受け取り、参照信号制御部106と同様に、まず、「クラスタ帯域幅」を算出する。
上記のように、端末100において、参照信号制御部106は、参照信号生成部107を制御して参照信号形成方法を切り替える。
上記した実施の形態1及び実施の形態2では、クラスタ数又はクラスタ帯域幅に応じて、端末100における参照信号の送信方法及び基地局200におけるチャネル推定方法の両方が切り替わる場合について説明した。しかしながら、基地局200におけるチャネル推定方法だけを切り替えても良い。すなわち、端末100における参照信号の送信方法は送信方法(a)又は送信方法(b)で固定として、クラスタ数又はクラスタ帯域幅に応じて基地局200におけるチャネル推定方法を切り替えても良い。こうすることでも、実施の形態1及び実施の形態2に近い効果が得られる。
