Abstract

The present invention relates to a method and an apparatus for a user equipment receiving MBMS service processing a semi-permanent scheduling from an MBSFN subframe. A method for a user equipment receiving the multimedia broadcast multicast service (MBMS) processing a downlink scheduling in a mobile communication system of the present invention comprises: a detection step of detecting the occurrence of the downlink scheduling in a random transmission time interval; a decision step of deciding whether to process the downlink scheduling, depending on whether the user equipment is set to a transmission mode 9 or whether the transmission time interval belongs to a multimedia broadcast multicast service single frequency network (MBSFN) subframe; and a processing step of processing or disregarding the downlink scheduling based on the result of the decision.

Claims

1. A method by a terminal in a mobile communication system, the method comprising:

receiving configuration information for a multimedia broadcast/multicast service frequency network (MBSFN) subframe;

configuring a downlink scheduling for a certain transmission time interval (TTI); and

if the terminal is configured with a transmission mode 9 and a subframe corresponding to the TTI is the MBSFN subframe based on the configuration information, processing the subframe based on the downlink scheduling for the TTI.

2. The method of claim 1, further comprising:

identifying whether a measurement gap is not configured in the TTI.

3. The method of claim 2, wherein the processing of the subframe based on the downlink scheduling comprises:

if the measurement gap is not configured in the TTI, processing the downlink scheduling for the TTI.

4. The method of claim 1, further comprising:

if the subframe corresponding to the TTI is not the MBSFN subframe, process the subframe based on the downlink scheduling for the TTI.

5. The method of claim 1, wherein the downlink scheduling is configured through an activated semi-persistent scheduling.

6. The method of claim 1, wherein the configuration information comprises an MBSFN subframe configuration list included in the system information block type 2.

7. The method of claim 6, wherein the MBSFN subframe is indicated by the MBSFN subframe configuration list.

8. A terminal in a mobile communication system, the terminal comprising:

a transceiver configured to transmit and receive signals to and from a base station; and

a controller configured to;

control the transceiver to receive configuration information for a multimedia broadcast/multicast service frequency network (MBSFN) subframe,

configure a downlink scheduling for a certain transmission time interval (TTI), and

if the terminal is configured with a transmission mode 9 and a subframe corresponding to the TTI is the MBSFN subframe based on the configuration information, process the subframe based on the downlink scheduling for the TTI.

9. The terminal of claim 8, wherein the controller is further configured to identify whether a measurement gap is not configured in the TTI.

10. The terminal of claim 9, wherein the controller is further configured to, if the measurement gap is not configured in the TTI, process the subframe based on the downlink scheduling for the TTI.

11. The terminal of claim 10, wherein the controller is further configured to, if the subframe corresponding to the TTI is not the MBSFN subframe, process the subframe based on the downlink scheduling for the TTI.

12. The terminal of claim 8, wherein the downlink scheduling is configured through an activated semi-persistent scheduling.

13. The terminal of claim 8, wherein the configuration information comprises an MBSFN subframe configuration list included in the system information block type 2.

14. The terminal of claim 13, wherein the MBSFN subframe is indicated by the MBSFN subframe configuration list.
