Abstract

The present specification discloses a transmission/reception method for a machine type communication (MTC) apparatus. The transmission/reception method for the MTC apparatus may comprise the steps of: receiving, by the MTC apparatus, setting information about a multicast-broadcast single-frequency network (MBSFN) subframe from a base station; receiving, by the MTC apparatus, downlink data for the MTC apparatus, on a data region of the MBSFN subframe; and receiving, by the MTC apparatus, a cell-specific reference signal (CRS) only on a portion of the resource blocks (RBs) in the whole system bandwidth of the data region in the MBSFN subframe. Here, the CRS received only on the portion of RBs may be transmitted while electric power is increased by means of the base station.

Claims10

Dependent claims

A method for receiving a signal of a first physical downlink shared channel (PDSCH), the method performed by a wireless device and comprising:

receiving first information specifying a plurality of subframes used for the wireless device;
receiving second information specifying at least one multimedia broadcast multicast service single frequency network (MBSFN) subframe;
determining multiple downlink subframes, to receive the signal of the first PDSCH, based on the plurality of subframes specified in the first information,
wherein the multiple downlink subframes include at least one MBSFN subframe specified by the second information;
receiving the signal of the first PDSCH which is repeated over the determined multiple downlink subframes;
and
if the signal of the first PDSCH includes a first system information block (SIB), determining that a signal of a second PDSCH including a data other than the first SIB is not transmitted in the determined multiple downlink subframes,
wherein the first SIB is dedicated for the wireless device and different from a SIB for a user equipment (UE) used by a user.
