Method and apparatus for user equipment receiving MBMS service processing semi-permanent scheduling from MBSFN subframe in wireless communication system
First Claim
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;
receiving a downlink assignment to receive a physical downlink shared channel (PDSCH) for a first transmission time interval (TTI); and
when the terminal is configured with a transmission mode 9 and a subframe corresponding to a second TTI is the MBSFN subframe based on the configuration information;
receiving a physical multicast channel (PMCH) in the subframe if the second TTI is different from the first TTI, andreceiving the PDSCH in the subframe based on the downlink assignment if the second TTI corresponds to the first TTI.

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.
