Abstract
A method for hybrid automatic repeat request HARQ signalling in a communications system is disclosed. The method includes defining, in a communications apparatus, a link-independent HARQ entity for one link direction, wherein the defined entity includes a resource allocation for one or more of forward link and reverse link data, the resource allocation including at least one HARQ process having a process identification, each HARQ process having a unique HARQ identification, a data allocation having a predetermined timing offset with respect to the resource allocation, and a HARQ acknowledgement allocation having a predetermined timing offset with respect to the data allocation, wherein the timing offset of the HARQ acknowledgement with respect to the data allocation is determined in terms of time division duplexing TDD frames and independently of a forward link-reverse link ratio.
