Abstract:
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).
