Title (EN) COMMUNICATION DEVICE AND COMMUNICATION METHOD
(FR) DISPOSITIF DE COMMUNICATION ET PROCÉDÉ DE COMMUNICATION
(JA) 通信装置及び通信方法
Abstract:
(EN) The present invention provides a communication device that appropriately implements SR communication and MU communication. This communication device that operates as a base station is provided with: a determination unit for determining a communication status within a BSS thereof; and a control unit for controlling transmission and reception of a signal relating to terminal connection change to and from surrounding base stations in accordance with the communication status. The determination unit determines the presence of a small number of terminals that are not included in the distribution of an implementation status of spatial reuse communication or multiuser communication of all terminals under the command thereof, and transmits a signal requesting the small number of terminals to connect with the surrounding base stations or a signal inquiring of the surrounding base stations about the acceptance of the small number of terminals.
(FR) La présente invention concerne un dispositif de communication qui met en œuvre de manière appropriée une communication SR et une communication MU. Ce dispositif de communication qui fonctionne comme une station de base comprend : une unité de détermination conçue pour déterminer un état de communication dans un BSS associé ; et une unité de commande conçue pour commander la transmission et la réception d'un signal relatif à un changement de connexion de terminal à destination et en provenance de stations de base environnantes conformément à l'état de communication. L'unité de détermination détermine la présence d'un petit nombre de terminaux qui ne sont pas inclus dans la distribution d'un état de mise en œuvre de communication de réutilisation spatiale ou de communication multiutilisateur de tous les terminaux sous commande, et transmet un signal demandant au petit nombre de terminaux de se connecter aux stations de base environnantes ou un signal interrogeant les stations de base environnantes concernant l'acceptation du petit nombre de terminaux.
(JA) SR通信やMU通信を好適に実現する通信装置を提供する。 基地局として動作する通信装置は、自分のBSS内での通信状況を判定する判定部と、周辺の基地局との間で、前記通信状況に応じて、端末の接続変更に関する信号の送受信を制御する制御部を具備する。前記判定部は、配下の端末全体の空間再利用通信又はマルチユーザ通信の実施状況の分布から外れた少数の端末の存在を判定し、前記少数の端末に対して前記周辺の基地局への接続を要請する信号し、又は、前記周辺の基地局を少数の端末の受け入れを問い合わせる信号を送信する。
