Abstract:
1. A method of controlling the allocation of hybrid automatic repeat request (HARQ) resources during a semi-persistent scheduling session, the method comprising: reserving a subset of a plurality of HARQ process identifications (IDs) for a semi-persistent scheduling; determining a HARQ process ID for a downlink (DL) transmission associated with an allocation of a semi-persistent resource based at least in part on a system frame number (SFN) associated with the DL transmission, wherein the HARQ process ID is one of the subset of the plurality of HARQ process IDs reserved for semi-persistent scheduling and the HARQ process ID is determined without an identity of any HARQ process ID being included in an activation message for the semi-persistent resource; and receiving a subsequent allocation that includes the HARQ process ID via a physical downlink control channel (PDCCH), wherein the subsequent allocation is not for a transmission or retransmission associated with the semi-persistent resource.
