Title (EN) RADIO TERMINAL APPARATUS AND METHOD THEREFOR
(FR) APPAREIL TERMINAL RADIO ET PROCÉDÉ POUR CELUI-CI
(JA) 無線端末装置及びその方法
Abstract:
(EN) Radio terminals (1A, 1B, 1C) each receive a broadcast/multicast signal (220) from a cellular communication network (10). The representative terminal (1A) receives response messages from the nearby radio terminals (1B, 1C) via D2D communications (231, 232). Each response message is generated on the basis of the reception of the broadcast/multicast signal (220) by the respective nearby radio terminals (1B, 1C). The representative terminal (1A) generates a representative response message and transmits the representative response message to the cellular communication network (10) or to another node (7) via an uplink transmission (240). In this way, it is possible to contribute to greater efficiency of transmission of response messages, for example, related to a broadcast/multicast service, by radio terminals.
(FR) Selon l'invention, des terminaux radios (1A, 1B, 1C) reçoivent chacun un signal de diffusion/multidiffusion (220) provenant d'un réseau de communication cellulaire (10). Le terminal représentatif (1A) reçoit des messages de réponse provenant des terminaux radios proches (1B, 1C) par communications D2D (231, 232). Chaque message de réponse est produit en fonction de la réception du signal de diffusion/multidiffusion (220) par les terminaux radios proches respectifs (1B, 1C). Le terminal représentatif (1A) produit un message de réponse représentatif et transmet le message de réponse représentatif au réseau de communication cellulaire (10) ou à un autre nœud (7) par une transmission de liaison montante (240). De cette manière, il est possible de contribuer à une plus grande efficacité de transmission de messages de réponse, par exemple, associés à un service de diffusion/multidiffusion, par des terminaux radios.
(JA) 各無線端末(1A、1B、1C)は、ブロードキャスト/マルチキャスト信号(220)をセルラー通信ネットワーク(10)から受信する。代表端末(1A)は、近隣無線端末(1B、1C)から応答メッセージをD2D通信(231、232)を介して受信する。各応答メッセージは、各近隣無線端末(1B、1C)によるブロードキャスト/マルチキャスト信号(220)の受信に基づいて生成される。代表端末(1A)は、代表応答メッセージを生成し、これをセルラー通信ネットワーク(10)又は他のノード(7)にアップリンク送信(240)を介して送信する。これにより、例えば、ブロードキャスト/マルチキャスト・サービスに関する応答メッセージの無線端末による送信の効率化に寄与できる。
