Title
(EN) MULTIPLEXING OF CONTROL INFORMATION AND DATA FOR WIRELESS COMMUNICATION
(FR) MULTIPLEXAGE DES INFORMATIONS DE COMMANDE ET DES DONNÉES POUR UNE COMMUNICATION SANS FIL
Abstract
(EN) Techniques for sending control information in a wireless communication system are described. A user equipment (UE) may be configured to periodically send control information (e.g., CQI information) and may receive an assignment of control resources for sending the control information. The UE may also receive an assignment (e.g., a dynamic assignment or a semi-persistent assignment) of data resources for sending data. The UE may send the control information (i) on the control resources if the control and data resources do not coincide in time or (ii) on a designated portion of the data resources if the control and data resources coincide in time. The UE may generate at least one SC-FDMA symbol with the control information sent on the control resources or the designated portion of the data resources. The UE can maintain a single-carrier waveform for each SC-FDMA symbol.
(FR) La présente invention concerne des techniques permettant d'envoyer des informations de commande dans un système de communication sans fil. Un équipement utilisateur (UE) peut être configuré pour envoyer périodiquement des informations de commande (des informations d'amélioration continue de la qualité, par exemple) et peut recevoir une affectation des ressources de commande pour envoyer les informations de commande. L'UE peut également recevoir une affectation (par exemple, une affectation dynamique ou une affectation semi-permanente) des ressources de données pour envoyer des données. L'UE peut envoyer les informations de commande (i) sur les ressources de commande si les ressources de commande et de données ne coïncident pas dans le temps ou (ii) sur une partie désignée des ressources de données si les ressources de commande et de données coïncident dans le temps. L'UE peut produire au moins un symbole SC-FDMA avec les informations de commande envoyées sur les ressources de commande ou sur la partie désignée des ressources de données. L'UE peut entretenir une forme d'onde à porteuse unique pour chaque symbole SC-FDMA.
