Abstract
An apparatus for wireless communication may allocate resources for multicarrier wireless communication. The apparatus may be enabled for cross-carrier signaling and semi-persistent scheduling on at least one carrier. Semi-persistent scheduling may be enabled by deriving a resource, such as a PHICH resource, for uplink HARQ operation using at least part of a demodulation reference signal field. The resource may be chose to reduce PHICH collision and may be based on a starting physical block of uplink data transmission. Cross-carrier signaling may be enabled by an information field, such as a carrier indicator field in the PDCCH, not enabled when cross-carrier signaling is not enabled.
