Abstract: As one of energy saving mechanisms for a new radio access technology (NR), a power saving state may be defined according to the present invention. More specifically, a user equipment (UE) enters an active state, monitors a first radio frequency (RF) bandwidth for the active state, enters the power saving state, and monitors a second RF bandwidth, which is restricted to M MHz within the first RF bandwidth, for the power saving state.

Abstract: A method and apparatus for allocating resources for a machine type communication user equipment (MTC UE) in a wireless communication system is provided. A base station indicates a transport block size (TBS) directly, adapts a code rate according to repetition numbers across multiple subframes in a MTC physical downlink shared channel (M-PDSCH) for the MTC UE, and allocates resources for the M-PDSCH by using the indicated transport block size and the adapted code rate. The TBS may be determined based on a modulation and coding scheme (MCS) only.

Abstract: According to one discourse of the present specification, a method for receiving information by a machine type communication (MTC) device is provided. The method of receiving the information may comprise the steps of: monitoring cell-specific control information within a common search space; and monitoring MTC device-specific control information within a UE-specific search space. Here, a resource region in which the common search space (CSS) is located and a resource region in which the UE-specific search space (USS) is located may be configured not to overlap each other.

Abstract: A method for receiving a signal by a terminal in a wireless communication system according to an embodiment of the present invention can comprise a step for determining REGs, which are to be assumed that the same precoding is used, among REGs comprised in a control resource set on the basis of information relating to precoder granularity, and thus monitoring a control channel candidate Particularly, if a part of resource blocks overlaps another resource region and particular resource blocks in the resource blocks are no longer contiguous due to the overlapping, the terminal can comprise an assumption that the same precoding is used with respect to the REGs comprised in the particular resource blocks even if the information relating to the precoder granularity corresponds to first configuration.
