Abstract

A method for communicating between a network and a dual receiver UE includes receiving first signaling from a first network node at a first frequency, and receiving second signaling via a PtM control channel from a second network node at a second frequency. The method further includes receiving a request from the second network node at the second frequency, such that the request is carried on the PtM control channel, and transmitting to the first network node a response to the request from the second network node. An alternative method includes receiving communications from a first network node, and identifying that the first network node lacks uplink capabilities. This method may further include identifying that the first network node provides a MBMS service, and receiving the MBMS service from the first network node despite the identification of the lack of uplink capabilities.

Claims

1. A method of receiving a multimedia broadcast/multicast (MBMS) service in a mobile communication system, said mobile communication system including a network having at least one cell, a first user equipment (UE) and a second UE, said method comprising:

receiving, in said second UE, a first indicator from said network;

identifying, by said second UE, that a specific cell of said at least one cell lacks uplink capabilities based on said received first indicator, wherein said first indicator indicates an operation of said specific cell providing only MBMS service; and

receiving, in said second UE, the MBMS service from said specific cell.

2. The method according to claim 1, wherein said first indicator is received through a broadcast control channel (BCCH) that is a logical channel located between a radio link control (RLC) layer and a medium access control (MAC) layer.

3. The method according to claim 1, wherein said MBMS service is received in said second UE on an MBMS only frequency.

4. The method according to claim 1, wherein said second UE is capable of selecting said specific cell using said first indictor to receive said MBMS service while said first UE is not capable of selecting said specific cell due to said first UE'"'"'s inability to identify said specific cell.

5. The method according to claim 1, further comprising:

receiving, in said second UE, a second indicator from said network, wherein said second indicator indicates that said second UE is permitted to receive said MBMS service, and said receiving of said MBMS service is performed in response to said receiving of said second indicator.

6. The method according to claim 1, further comprising:

receiving, in said second UE, system information from another cell of said at least one cell, wherein said system information indicates that said other cell has both uplink and downlink capabilities.

7. The method according to claim 6, further comprising:

receiving, in said second UE, frequency information from said other cell, said frequency information indicating a transmission frequency of said specific cell.

8. The method according to claim 1, further comprising:

receiving, in said second UE, a list of at least one different cell which transmits at a frequency different than said specific cell and which provides cell coverage which overlaps at least a portion of cell coverage provided by said specific cell.

9. A method of providing a multimedia broadcast/multicast service (MBMS) service in a mobile communication system, said mobile communication system including a network having at least one cell and at least one user equipment (UE), said method comprising:

transmitting a first indicator from said network to said at least one user equipment, wherein said first indicator indicates that a specific cell of said at least one cell lacks uplink capabilities, wherein said first indicator is used to indicate an operation of said specific cell providing only MBMS service; and

providing the MBMS service to said at least one UE.

10. The method according to claim 9, wherein said first indicator is transmitted through a broadcast control channel (BCCH) that is a logical channel located between a radio link control (RLC) layer and a medium access control (MAC) layer.

11. The method according to claim 9, wherein said MBMS service is provided to said at least one UE on an MBMS only frequency.

12. The method according to claim 9, further comprising:

transmitting a second indicator from said specific cell to said at least one UE, wherein said second indicator indicates that said at least one UE is permitted to receive said MBMS service.

13. The method according to claim 9, wherein said at least one UE comprises a first UE and a second UE, and said second UE is capable of selecting said specific cell using said first indicator to receive said MBMS service while said first UE is not capable of selecting said specific cell due to said first UE'"'"'s inability to identify said specific cell.

14. The method according to claim 9, further comprising:

transmitting frequency information to said at least one UE from another cell of said at least one cell, said frequency information indicating a transmission frequency of said specific cell.

15. The method according to claim 9, further comprising:

transmitting a list of at least one different cell which transmits at a frequency different than said specific cell and which provides cell coverage which overlaps at least a portion of cell coverage provided by said specific cell.

16. The method according to claim 9, further comprising:

transmitting at least one identity from said specific cell to said at least one UE, wherein said at least one identity identifies another cell of said at least one cell.

17. The method according to claim 16, wherein said specific cell and said other cell are managed by a single base station.

18. The method according to claim 16, wherein said specific cell and said other cell are separately managed by distinct base stations.
