CA 2668575

Systems and methodologies are described that facilitate communicating reverse link control information over OFDMA control channel (s) and CDMA control channel (s). Dedicated OFDMA control channel resources can be assigned to mobile device (s). Control information related to one or more logical control channels can be generated by a mobile device (204). Further, a physical control channel type (e.g., OFDMA control channel or a CDMA control channel) can be selected (214) for sending the control information via the reverse link. For example, control information associated with periodic, logical control channels can be multiplexed (216) and sent over the OFDMA control channel (e.g., utilizing the dedicated OFDMA control channel resources) while control information related to non-periodic, logical control channels can be transmitted over the CDMA control channel.

Les systèmes et méthodologies décrits facilitent la communication d'informations de commande de liaison inverse sur un (ou des) canal(ux) de commande OFDMA et CDMA. Les ressources dédiées du canal de commande OFDMA peuvent être affectées à un (ou des) terminal(ux) mobile(s). Des informations de commande associées à un ou plusieurs canaux de commande logiques peuvent être générées par un dispositif mobile. En outre, le type du canal de commande physique (ex. canal de commande OFDMA ou CDMA) peut être sélectionné pour l'envoi des informations de commande via la liaison inverse. Par exemple, les informations de commande associées à des canaux de commande logiques périodiques peuvent être multiplexées et envoyées sur le canal de commande OFDMA (par exemple, en utilisant les ressources dédiées du canal de commande OFDMA), alors que les informations de commande associées à des canaux de commande logiques non périodiques peuvent être transmises sur le canal de commande CDMA.
