Abstract
A method and apparatus are disclosed for efficient hybrid automatic repeat request (HARQ) process utilization for semi-persistent and dynamic data transmissions, wherein a reserved HARQ process identification (ID) can be reused. A subset of a plurality of HARQ process IDs is reserved to use for a semi-persistent allocation, and data is transmitted based on the semi-persistent allocation. A dynamic allocation is received via a physical downlink control channel (PDCCH). At least one of the reserved HARQ process IDs is selectively used for transmitting data based on the dynamic allocation.
