Abstract

Disclosed is a radio (wireless) communication system providing a radio communication service and the terminal, and more particularly, to the method for receiving a MBMS service effectively by considering of time information related to a MBMS service transmission scheme.

Claims

1. A method of receiving a point-to-multipoint service in wireless communication system, the method comprising:

receiving time information related to a multi-cell transmission scheme for the point-to-multipoint service; and

performing a next operation according to the received time information.

2. The method of claim 1, wherein the next operation is performed by determining whether the point-to-multipoint service is provided using the multi-cell transmission scheme.

3. The method of claim 1, wherein the point-to-multipoint service is received based on the time information if the point-to-multipoint service is provided using the multi-cell transmission scheme.

4. The method of claim 1, wherein the multi-cell transmission scheme is MBSFN (MBMS Single Frequency Network).

5. The method of claim 1, wherein the time information indicates a specific time when to perform the multi-cell transmission scheme.

6. The method of claim 1, wherein the time information is received via a SIB (System Information Block).

7. The method of claim 1, wherein the time information is received through a BCH (Broadcast Channel) or a PDCCH (Physical Downlink Control Channel).

8. The method of claim 1, wherein the time information is related to TTI (Transmission Time Interval) information or frame information.

9. The method of claim 1, wherein the time information indicates at least one of a time pattern, a starting time, an ending time, or a time period that the multi-cell transmission scheme is performed.

10. A method of receiving a point-to-multipoint service in wireless communication system, the method comprising:

receiving time information related to a multi-cell transmission scheme for the point-to-multipoint service; and

performing a measurement process or a monitoring of a downlink channel with consideration of the received time information.

11. The method of claim 10, wherein the measurement process or the monitoring of the downlink channel is not performed at a time indicated by the received time information if a capability of corresponding terminal does not satisfy a certain condition.

12. The method of claim 11, wherein the capability of corresponding terminal is determined by whether or not the corresponding terminal is capable to receive a transmitted channel or a transmitted frame in the multi-cell transmission scheme.

13. The method of claim 12, wherein the multi-cell transmission scheme is MBSFN (MBMS Single Frequency Network).

14. The method of claim 10, wherein the point-to-multipoint service is a MBMS service.

15. A mobile terminal for receiving a point-to-multipoint service in a wireless communications system, the mobile terminal comprising:

a transceiver adapted to transmit or receive the point-to-multipoint service;

a memory adapted to store the transmitted or received point-to-multipoint service via the transceiver or from an external source; and

a processor cooperating with the transceiver and the memory and adapted to perform the steps of,

receiving time information related to a multi-cell transmission scheme for the point-to-multipoint service; and

performing a measurement process or a monitoring of a downlink channel with consideration of the received time information.
