Claim 0:
1. A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:
receiving a radio resource control (RRC) message, the RRC message including configuration information that indicates one or more uplink hybrid automatic repeat request (HARQ) process identifications (IDs) for use with an uplink semi-persistent resource;
receiving a first physical downlink control channel (PDCCH) transmission, the first PDCCH transmission activating the uplink semi-persistent resource for use by the WTRU;
determining a first uplink HARQ process ID for a first uplink transmission using the uplink semi-persistent resource, wherein the first uplink HARQ process ID is one of the one or more uplink HARQ process IDs configured for use with the uplink semi-persistent resource, and the first uplink HARQ process ID is determined based at least in part on a system frame number (SFN) associated with the first uplink transmission; and
receiving a second PDCCH transmission, the second PDCCH transmission comprising a dynamic uplink allocation associated with the first uplink HARQ process ID.
