Abstract

Methods and apparatus for assigning, identifying and controlling broadcast transmissions are disclosed. A broadcast flow is assigned to a broadcast logical channel of the physical resources of a wireless communication channel. A broadcast channel control message indicative of parameters of the broadcast logical channel is generated. Upon receipt, the broadcast channel control message is processed and used to accordingly process the received broadcast transmission.

Claims

1. A wireless communication device comprising:

a memory; and

a processor coupled with the memory, the processor configured to process a broadcast channel control message indicative of parameters of transmission parameters of at least one broadcast transmission to be received by the wireless communication device, wherein the processor is further configured to utilize information of the broadcast channel control message for processing the at least one broadcast transmission for one ultra-frame.

2. The wireless communication device of claim 1, wherein the ultra-frame comprises forty-eight super-frames.

3. The wireless communication device of claim 1, wherein the processor is configured to determine an error correction code used for the at least one broadcast transmission from the broadcast channel control message.

4. The wireless communication device of claim 1, wherein the processor is configured to determine a scrambling sequence used for the at least one broadcast transmission from the broadcast channel control message.

5. A method comprising:

processing a broadcast channel control message indicative of parameters of transmission parameters of at least one broadcast transmission to be received by a wireless communication device; and

processing the at least one broadcast transmission according to the parameters, wherein the processing the at least one broadcast transmission comprises processing using the parameters for one ultra-frame.

6. The method of claim 5, wherein the ultra-frame comprises forty-eight superframes.

7. The method of claim 5, wherein processing comprises processing using an error correction code in the broadcast channel control message.

8. The method of claim 5, wherein processing comprises processing using a scrambling sequence in the broadcast channel control message.

9. An apparatus comprising:

means for processing a broadcast channel control message indicative of parameters of transmission parameters of at least one broadcast transmission to be received by a wireless communication device; and

means for processing the at least one broadcast transmission according to the parameters, wherein the means for processing the at least one broadcast transmission comprises means for processing using the parameters for one ultra-frame.

10. A processor readable medium including instructions thereon that may be utilized by one or more processors, the instructions comprising:

instructions for processing a broadcast channel control message indicative of parameters of transmission parameters of at least one broadcast transmission to be received by a wireless communication device; and

instructions for processing the at least one broadcast transmission according to the parameters, wherein the instructions for processing the at least one broadcast transmission comprise instructions for processing using the parameters for one ultra-frame.
