Abstract

In accordance with an example embodiment of the present invention, a method is disclosed that comprises receiving a first signaling message from a transmitting station indicating a burst reception timing on a broadcast receiving channel; sending a second signaling message to a coupled base station including the burst reception timing; receiving a resource allocation message from the coupled base station; and allocating a time slot for a transmitting channel based at least in part on the resource allocation message in such a way that transmitting data on the allocated transmitting channel during the allocated time slot does not interfere with receiving data on the broadcast receiving channel.

Claims

1. A method, comprising:

receiving a first signaling message from a transmitting station indicating a burst reception timing on a broadcast receiving channel;

sending a second signaling message to a coupled base station including the burst reception timing;

receiving a resource allocation message from the coupled base station; and

allocating a time slot for a transmitting channel based at least in part on the resource allocation message in such a way that transmitting data on the allocated transmitting channel during the allocated time slot does not interfere with receiving data on the broadcast receiving channel.

2. The method of claim 1, wherein the allocated time slot for the transmitting channel does not overlap time slot in the burst reception timing for the broadcast receiving channel.

3. The method of claim 1, further comprising:

determining an acceptable interference level of transmitting data on the transmitting channel for the broadcast receiving channel during the burst reception timing in terms of a data redundancy rate;

sending the acceptable interference level to the coupled base station; and

allocating the transmitting channel in such a way that the interference of transmitting data on the transmitting channel for the broadcast receiving channel is within the acceptable interference level.

4. The method of claim 3, wherein determining the acceptable interference level comprises considering at least one of a modulation scheme, an interleaving scheme, a coding scheme and a reception power level of the broadcast receiving channel and determining the data redundancy rate in terms of the redundancy data as a percentage of total transmission data.

5. The method of claim 4, wherein allocating the transmitting channel comprises allocating a time slot for the transmitting channel that partially overlaps a time slot in the burst reception timing for the broadcast receiving channel in such a way that the interference of transmitting data during the time slot for the transmitting channel to the broadcast receiving channel is within the acceptable interference level.

6. The method of claim 5, wherein the burst reception timing comprises at least one time slot for burst reception indicated by at least one of a burst reception start time, a burst reception duration, and a burst reception interval.

7. The method of claim 6, wherein receiving the first signaling message further comprises receiving a synchronization time advance that comprises at least one of a radio frequency (RF) part frequency synthesis stabilization, orthogonal frequency-division multiplexing (OFDM) demodulator synchronization loop stabilization, gain control stabilization, and channel estimation filter buffer filling.

8. The method of claim 1, further comprising

sending data on the allocated transmitting channel and receiving broadcast burst transmission at the same time.

9. An apparatus, comprising:

a broadcast receiver configured to;

receive a first signaling message from a transmitting station indicating a burst reception timing on a broadcast receiving channel; and

receive a broadcast burst transmission;

a transceiver configured to;

transmit to a coupled base station a second signaling message including the burst reception timing; and

receive a resource allocation message from the coupled base station; and

an interworking module configured to;

allocate a time slot for a transmitting channel according to the resource allocation message from the coupled base station in such a way that transmitting data on the transmitting channel during the allocated time slot does not interfere with receiving data on the broadcast receiving channel.

10. The apparatus of claim 9, wherein the interworking module is further configured:

to determine an acceptable interference level of transmitting data on the transmitting channel for the broadcast receiving channel in terms of a data redundancy rate; and

to send the acceptable interference level to the coupled base station.

11. The apparatus of claim 10, wherein the interworking module is further configured to allocate the time slot for the transmitting channel according to the resource allocation message in such a way that the interference of transmitting data on the transmitting channel during the allocated time slot to the broadcast receiving channel is within the acceptable interference level.

12. The apparatus of claim 9, wherein the apparatus is one of a LTE user equipment (UE), a WiMax UE, and a 4^th generation wireless UE.

13. The apparatus of claim 9, wherein the broadcast receiver is configured to receive TV broadcast signals in compliance with one of a MediaFLO transmission standard and a DVB-H transmission standard.

14. The apparatus of claim 9, wherein the apparatus is configured to transmit data on the allocated transmitting channel and to receive broadcast burst transmission at a same time.

15. An apparatus, comprising:

a transceiver configured

to receive a signaling message from a user equipment (UE) indicating a burst reception timing on a broadcast receiving channel of the UE; and

a scheduler configured

to allocate a time slot for a transmitting channel of the UE in such a way that transmitting data by the UE on the allocated transmitting channel during the allocated time slot does not interfere with receiving data by the UE on the broadcast receiving channel.

16. The apparatus of claim 15, wherein the signaling message from the UE further indicates an acceptable interference level in terms of a redundancy data rate.

17. The apparatus of claim 16, wherein the scheduler is further configured to allocate the time slot for the transmitting channel of the UE in such a way that the interference from transmitting data on the allocated transmitting channel during the time slot to the broadcast receiving channel of the UE is within the acceptable interference level.

18. The apparatus of claim 15, wherein the apparatus is one of a LTE eNB, eNB-Adanced, and a generic 4^th generation (4G) base station.

19. The apparatus of claim 15, wherein the transceiver is further configured:

to receive data transmitted on the allocated transmitting channel from the UE; and

to transmit data to the UE at same time.

20. The apparatus of claim 17, wherein the apparatus is coupled with one of a MediaFLO mobile TV transmitting station and a DVB-H mobile TV transmitting station.
