Abstract: One disclosure in the present specification presents a method for a wireless device to receive a paging message. The method may comprise: a step of deciding a wake up signal occasion (WUSO) window for attempting to receive a wake up signal (WUS); and a step of monitoring a downlink control channel during a paging window so as to attempt to receive a paging message, if the WUS is received within the decided WUSO window. Here, the WUSO window may be decided according to a duration size and offset.

Abstract: The present disclosure provides a method and apparatus for transmitting and receiving a signal in a wireless communication system. When a user equipment (UE) is configured with M resources within one periodicity based on a semi-persistent scheduling (SPS) configuration, a base station may configure N resources actually available to the UE in downlink control information (DCI). The UE may select some of the N resources to receive data. Accordingly, resources may be flexibly allocated to a plurality of UEs without delay due to data jitter.

Abstract: According to an embodiment of the present invention a UE may receive a first system information block (SIB) including a system information (SI) request-related configuration including a physical random access channel configuration; transmit a random access (RA) preamble for an SI request based on the PRACH configuration; and receive, in response to the RA preamble, a second SIB different from the first SIB, wherein the SI request-related configuration may include first information related only to a first type UE with reduced capability to support a smaller bandwidth than a second type UE, and second information common for the first type UE and the second type UE, and the UE may be the first type UE and may perform the RA preamble transmission by determining an RA association period and an RA occasion based on both of the first information and the second information in the SI request-related configuration.

Abstract: The present specification discloses an invention relating to a method for transmitting an MTC physical downlink control channel (MPDCCH) by a base station in a wireless communication system supporting machine type communication (MTC). According to the present invention, a base station transmits, to a terminal, configuration information related to the transmission of an MPDCCH and maps the MPDCCH onto multiple resource elements (REs) of at least one first symbol constituting a first slot of a special subframe. The special subframe is a subframe in which, among symbols constituting the subframe, the number of symbols for data transmission is smaller than or equal to a predetermined number. The base station transmits the MPDCCH to the terminal over the multiple resource elements, wherein the mapping step is performed by copying at least one second symbol of a second slot adjacent to the first slot onto the at least one first symbol.
