Systems and methodologies are described that facilitate allocation of uplink acknowledgement (ACK) resources for a wireless communication system. Various aspects described herein facilitate explicit creation and transmission of a bundled assignment of downlink communication resources and uplink resources for ACK transmission, thereby facilitating overhead-efficient ACK allocation for users that can communicate pursuant to a persistent resource assignment without requiring scheduling information from an associated control channel. Additionally, indexing schemes for uplink ACK resources are provided herein to facilitate ACK allocation for systems in which both scheduled and persistent users can communicate at a common transmission time interval (TTI).

L'invention concerne des systèmes et des procédés qui facilitent une attribution de ressources d'accusé de réception (ACK) en liaison montante pour un système de communication sans fil. Divers aspects décrits ici facilitent une création et une transmission explicites d'une allocation groupée de ressources de communication en liaison descendante et de ressources en liaison montante pour une transmission d'ACK, facilitant ainsi une attribution d'ACK économique pour des utilisateurs qui peuvent communiquer conformément à une affectation de ressources persistante sans avoir besoin d'informations de programmation provenant d'un canal de contrôle associé. En outre, des schémas d'indexation pour des ressources d'ACK en liaison montant sont fournis ici pour faciliter une attribution d'ACK pour des systèmes dans lesquels des utilisateurs programmés et persistants peuvent communiquer à un intervalle de temps de transmission (TTI) commun.
