Abstract
(EN) A method and apparatus are described for allocating resources for an enhanced physical hybrid automatic repeat request (HARQ) channel (E-PHICH). A subset of an enhanced physical downlink control channel (E-PDCCH) may be allocated for use by the E-PHICH. The E-PDCCH may be defined by at least one of enhanced resource element groups (eREGs) and enhanced control channel elements (eCCEs). Each eCCE may be formed by grouping a plurality of eREGs. Each eREG may contain at least one resource element (RE). Alternatively, a subset of eREGs may be allocated as E-PHICH resources. E-PDCCH physical resource block (PRB) pairs may be selected as a resource for the E-PHICH. An indication of the number of the eCCEs may be broadcast to a wireless transmit/receive unit (WTRU).
(FR) L'invention porte sur un procédé et un appareil d'attribution de ressources pour un canal indicateur de demande automatique de répétition hybride (HARQ) physique amélioré (E-PHICH). Un sous-ensemble d'un canal de commande de liaison descendante physique amélioré (E-PDCCH) peut être attribué pour être utilisé par l'E-PHICH. L'E-PDCCH peut être défini par des groupes d'éléments de ressource améliorés (eREG) et/ou des éléments de canal de commande améliorés (eCCE). Chaque eCCE peut être formé par groupement d'une pluralité d'eREG. Chaque eREG peut contenir au moins un élément de ressource (RE). Selon une variante, un sous-ensemble d'eREG peut être attribué en tant que ressources E-PHICH. Des paires de blocs de ressources physiques (PRB) E-PDCCH peuvent être sélectionnés en tant que ressource pour l'E-PHICH. Une indication du nombre des eCCE peut être diffusée à destination d'une unité d'émission/réception sans fil (WTRU).
