Hybrid Automatic Repeat Request Process Mapping Rule
A method is provided for associating initial transmissions and retransmissions. The method includes determining a HARQ process ID for the initial transmission based upon a system frame number, a subframe number, a period associated with the initial transmission and/or a number of reserved HARQ process IDs. The method further includes associating the initial transmission with a retransmission based upon the HARQ process ID.
1 . A system, comprising:
a component configured to determine a HARQ process ID for an initial transmission based upon a system frame number.
2 . The system of claim 1 , wherein the system is a user agent.
3 . The system of claim 1 , wherein the system is an access device.
4 . The system of claim 1 , wherein the component is further configured to determine the HARQ process ID also based on a subframe number.
5 . The system of claim 4 , wherein the component is further configured to determine the HARQ process ID also based on a reserved number of HARQ Process IDs.
6 . The system of claim 5 , wherein the component is further configured to determine the HARQ process ID also based on a period.
7 . The system of claim 1 , wherein the initial transmission is associated with a semi-persistently scheduled resource.
8 . The system of claim 1 , wherein the initial transmission does not have a corresponding physical downlink control channel notification containing a HARQ process ID.
9 . A system, comprising:
a component configured to determine a HARQ process ID for an initial transmission based upon a subframe number, a system frame number, a number of reserved HARQ process IDs and a period associated with the initial transmission.
10 . The system of claim 9 , wherein the component determines the HARQ process ID for the initial transmission based on the following equation:
floor((i*10+j)/p)mod M, where
i=system frame number, j=subframe number, p=period, and M=number of reserved HARQ process IDs.
11 . The system of claim 9 , wherein the number of reserved HARQ process IDs and the period associated with the initial transmission are provided via radio resource control signaling.
12 . A method for associating initial transmissions and retransmissions, comprising:
determining a HARQ process ID for the initial transmission based upon a system frame number; and
associating the initial transmission with the HARQ process ID.
13 . The method of claim 12 , wherein determining further comprises basing the HARQ process ID on a subframe number.
14 . The method of claim 13 , wherein determining further comprises basing the HARQ process ID on a reserved number of HARQ process IDs.
15 . The method of claim 14 , wherein determining further comprises basing the HARQ process ID on a period.
16 . The method of claim 15 , wherein the initial transmission does not have a corresponding physical downlink control channel notification containing a HARQ process ID.
17 . A method for associating initial transmissions and retransmissions, comprising:
determining a HARQ process ID for the initial transmission based upon a subframe number; and
associating the initial transmission with the HARQ process ID.
18 . The method of claim 17 , wherein determining further comprises basing the HARQ process ID on a system frame number.
19 . The method of claim 18 , wherein determining further comprises basing the HARQ process ID on a reserved number of HARQ process IDs.
20 . The method of claim 19 , wherein determining further comprises basing the HARQ process ID on a period.
21 . The method of claim 20 , wherein the initial transmission does not have a corresponding physical downlink control channel notification containing a HARQ process ID.
22 . A method of associating initial transmissions and retransmissions comprising:
determining a HARQ process ID for the initial transmission based upon a system frame number, a subframe number, a number of reserved HARQ process IDs, and a period; and
associating the initial transmission with the HARQ process ID.
23 . The method of claim 22 , wherein determining is based on the following equation:
floor((i*10+j)/p)mod M, where
i=system frame number, j=subframe number, p=period, and M=number of reserved HARQ process IDs.
24 . The method of claim 22 , wherein the number of reserved HARQ process IDs and the period are provided via radio resource control signaling.
25 . A method for deriving a HARQ ID associated with a configured transmission comprising:
determining the HARQ ID based upon the following equation:
floor((SFN*10+subframe number)/(period of the configured scheduling))/mod(number of reserved HARQ Process IDs).
26 . The method of claim 25 , wherein the number of reserved HARQ process IDs and the period of the configured scheduling are provided via radio resource control signaling.
27 . The method of claims 25 , wherein the configured transmission is associated with a semi-persistently or configured resource.
28 . The method of claims 25 , wherein the configured transmission does not have a corresponding physical downlink control channel notification containing a HARQ process ID.
