摘要：
A downlink subframe on a single downlink carrier supports physical layer acknowledgment signaling for multiple physical uplink shared channel (PUSCH) transmissions. The physical layer acknowledgement signaling may take the form of physical hybrid ARQ indicator channel (PHICH) signaling. A base unit reserves resource elements groups (REGs) for default PHICH signaling of default PUSCH transmissions. The base unit reserves control channel elements (CCEs) for physical downlink control channel (PDCCH) signaling. A CCE contains multiple interleaved REGs. The base unit takes any unreserved CCEs and maps those CCEs for physical layer acknowledgement signaling of additional PUSCH transmissions.
