Abstract

In a method for scheduling resources, the method includes receiving a first control channel in a first subframe (426) as a part of wireless communication between a user equipment (102) and a network equipment (110) using a first type of radio access technology wherein the first control channel (408) includes a first scheduling grant for scheduling resources in a second subframe (424) using a second type of radio access technology. The method also includes receiving a second control channel in the first subframe using the first type of radio access technology wherein the second control channel includes a second scheduling grant for the scheduling resources in the first subframe using the first type of radio access technology.

Claims

1. A method comprising:

receiving a first control channel in a first subframe as a part of wireless communication between a user equipment and a network equipment using a first type of radio access technology wherein the first control channel includes a first scheduling grant for scheduling resources in a second subframe using a second type of radio access technology;

receiving a second control channel in the first subframe using the first type of radio access technology wherein the second control channel includes a second scheduling grant for the scheduling resources in the first subframe using the first type of radio access technology;

receiving a third control channel in the second subframe wherein the third control channel is configured according to the first scheduling grant.

2. The method of claim 1 wherein the grant includes a radio access technology indicator function.

3. The method of claim 1 wherein the first type of radio access technology is an HSPA radio technology and the second type of radio access technology is a long term evolution radio technology.

4. The method of claim 1 wherein the first type of radio access technology is a long term evolution radio technology and the second type of radio access technology is a HSPA radio technology.

5. An apparatus comprising:

a transceiver for receiving a first control channel in a first subframe using a first type of radio access technology wherein the first control channel includes a first scheduling grant for scheduling resources in a second subframe using a second type of radio access technology, for receiving a second control channel in the first subframe using the first type of radio access technology wherein the second control channel includes a second scheduling grant for scheduling resources in the first subframe using the first type of radio access technology, and for receiving a third control channel in the second subframe wherein the third control channel is configured according to the first scheduling grant;

a processor coupled to the transceiver wherein the processor is configured to process the first scheduling grant and the second scheduling grant to detect resource allocation for a second type of radio access technology and a first type of radio access technology.

6. The apparatus of claim 5 wherein the grant includes a radio access technology indicator function.

7. The apparatus of claim 5 wherein the first type of radio access technology is an HSPA radio technology and the second type of radio access technology is a long term evolution radio technology.

8. The apparatus of claim 5 wherein the first type of radio access technology is a long term evolution radio technology and the second type of radio access technology is a HSPA radio technology.
