Abstract:
(EN) A wireless communication device (100, 400) comprises: a modulation unit (130, 430) which modulates data that is disposed in a first resource region constituting a wireless signal and transmitted; a spread modulation unit (140, 440) which uses a code to subject data that is disposed in a second resource region provided in the first resource region and transmitted to spread modulation; a mapping unit (150, 470) which maps the data modulated by the modulation unit (130, 430) to the first resource region, and maps the data subjected to spread modulation by the spread modulation unit (140, 440) to the second resource region; and a wireless transmission unit (100c, 400c) which transmits a signal obtained by mapping by the mapping unit (150, 470).
(FR) L'invention concerne un dispositif de communication sans fil (100, 400) comprenant : une unité de modulation (130, 430) qui module des données disposées dans une première zone de ressource constituant un signal sans fil et transmises ; une unité de modulation d'étalement (140, 440) qui utilise un code afin de soumettre des données disposées dans une seconde zone de ressource située dans la première zone de ressource et transmises à une modulation d'étalement ; une unité de mappage (150, 470) qui mappe les données modulées par l'unité de modulation (130, 430) à la première zone de ressource, et mappe les données soumises à une modulation d'étalement par l'unité de modulation d'étalement (140, 440) à la seconde zone de ressource ; et une unité de transmission sans fil (100c, 400c) qui transmet un signal obtenu par mappage par l'unité de mappage (150, 470).
(JA) 無線通信装置(100、400)は、無線信号を構成する第1のリソース領域に配置されて送信されるデータを変調する変調部(130、430)と、前記第1のリソース領域内に設けられた第2のリソース領域に配置されて送信されるデータをコードを用いて拡散変調する拡散変調部(140、440)と、前記変調部(130、430)によって変調されたデータを前記第1のリソース領域にマッピングするとともに、前記拡散変調部(140、440)によって拡散変調されたデータを前記第2のリソース領域にマッピングするマッピング部(150、470)と、前記マッピング部(150、470)によるマッピングにより得られた信号を送信する無線送信部(100c、400c)とを有する。
