Abstract

A method, an apparatus, and a computer-readable medium for delivering content to end user via shared broadcast are provided. The apparatus may be a UE that determines to acquire a MBMS service. The UE tunes to a frequency provided by a first MNO to which the UE is not a subscriber in order to receive the MBMS service via a carrier shared by the first MNO and at least one other MNO. The UE receives the MBMS service on the frequency via the carrier shared by the first MNO and the at least one other MNO. The shared carrier may have a common SFN timing with respect to the first MNO and the at least one other MNO. The shared carrier may include a shared MBMS SDL carrier. The shared carrier may include a standalone shared carrier for receiving the MBMS service and control information associated with the MBMS service.

Claims

1. A method of wireless communication of a user equipment (UE), comprising:

determining to acquire a Multimedia Broadcast Multicast Service (MBMS) service;

tuning to a frequency provided by a first mobile network operator (MNO) to which the UE is not a subscriber in order to receive the MBMS service via a carrier shared by the first MNO and at least one other MNO; and

receiving the MBMS service on the frequency via the carrier shared by the first MNO and the at least one other MNO.

2. The method of claim 1, wherein the shared carrier comprises at least one of an unlicensed carrier or a shared MBMS supplemental downlink (SDL) carrier.

3. The method of claim 2, further comprising receiving control information for the MBMS service through a primary cell (PCell) of the first MNO, wherein the MBMS service is received through a secondary cell (SCell) shared by the first MNO and the at least one other MNO.

4. The method of claim 2, comprising receiving information regarding the shared MBMS SDL carrier through an Internet Protocol (IP) connection, wherein the tuning and the receiving are based on the received information regarding the shared MBMS SDL carrier.

5. The method of claim 1, wherein the shared carrier comprises at least one of a standalone shared carrier or a shared MBMS supplemental downlink (SDL) carrier for receiving the MBMS service and control information associated with the MBMS service.

6. The method of claim 5, further comprising receiving a frame timing and a system information block (SIB) via the standalone shared carrier without having previously received a primary synchronization signal (PSS) and a second synchronization signal (SSS) via the standalone shared carrier.

7. The method of claim 1, further comprising receiving information associated with the MBMS service via limited unicast communication with the first MNO, wherein the MBMS service is received based on the received information.

8. The method of claim 1, wherein the shared carrier comprises a multicast-broadcast single-frequency network (MBSFN) implemented by the first MNO and the at least one other MNO.

9. A method of wireless communication, comprising:

provisioning a Multimedia Broadcast Multicast Service (MBMS) service on a frequency provided by a first mobile network operator (MNO) via a carrier shared by the first MNO and at least one other MNO;

providing control information for acquiring the MBMS service; and

providing the MBMS service on the frequency via the carrier shared by the first MNO and the at least one other MNO.

10. The method of claim 9, wherein the shared carrier comprises at least one of an unlicensed carrier or a shared MBMS supplemental downlink (SDL) carrier.

11. The method of claim 10, wherein the control information for acquiring the MBMS service is provided through a primary cell (PCell) of the first MNO, wherein the MBMS service is provided through a secondary cell (SCell) shared by the first MNO and the at least one other MNO.

12. The method of claim 9, wherein the shared carrier comprises at least one of a standalone shared carrier or a shared MBMS supplemental downlink (SDL) carrier for providing the MBMS service and the control information associated with the MBMS service.

13. The method of claim 12, wherein providing the control information comprises transmitting a frame timing and a system information block (SIB) via the standalone shared carrier without having previously transmitted a primary synchronization signal (PSS) and a second synchronization signal (SSS) via the standalone shared carrier.

14. The method of claim 9, wherein the provisioning the MBMS service comprises providing information associated with the MBMS service via limited unicast communication provided by the first MNO.

15. The method of claim 9, wherein the shared carrier comprises a multicast-broadcast single-frequency network (MBSFN) implemented by the first MNO and the at least one other MNO.

16. An apparatus for wireless communication, the apparatus being a user equipment (UE), comprising:

a memory; and

at least one processor coupled to the memory and configured to;

determine to acquire a Multimedia Broadcast Multicast Service (MBMS) service;

tune to a frequency provided by a first mobile network operator (MNO) to which the UE is not a subscriber in order to receive the MBMS service via a carrier shared by the first MNO and at least one other MNO; and

receive the MBMS service on the frequency via the carrier shared by the first MNO and the at least one other MNO.

17. The apparatus of claim 16, wherein the shared carrier comprises at least one of an unlicensed carrier or a shared MBMS supplemental downlink (SDL) carrier.

18. The apparatus of claim 17, wherein the at least one processor is further configured to receive control information for the MBMS service through a primary cell (PCell) of the first MNO, wherein the MBMS service is received through a secondary cell (SCell) shared by the first MNO and the at least one other MNO.

19. The apparatus of claim 17, wherein the at least one processor is further configured to receive information regarding the shared MBMS SDL carrier through an Internet Protocol (IP) connection, wherein the at least one processor is configured to tune and to receive based on the received information regarding the shared MBMS SDL carrier.

20. The apparatus of claim 16, wherein the shared carrier comprises at least one of a standalone shared carrier or a shared MBMS supplemental downlink (SDL) carrier for receiving the MBMS service and control information associated with the MBMS service.

21. The apparatus of claim 20, wherein the at least one processor is further configured to receive a frame timing and a system information block (SIB) via the standalone shared carrier without having previously received a primary synchronization signal (PSS) and a second synchronization signal (SSS) via the standalone shared carrier.

22. The apparatus of claim 16, wherein the at least one processor is further configured to receive information associated with the MBMS service via limited unicast communication with the first MNO, wherein the MBMS service is received based on the received information.

23. The apparatus of claim 16, wherein the shared carrier comprises a multicast-broadcast single-frequency network (MBSFN) implemented by the first MNO and the at least one other MNO.
