Abstract: The present invention relates to a wireless communication system and, specifically, to a method comprising the steps of: repeatedly transmitting a PUSCH; and repeatedly receiving the PDSCH in a DL duration immediately following after repeated transmission of the PDSCH, wherein when a terminal operates in an in-band mode, each PDSCH is received from an OFDM symbol subsequent to a k-th OFDM symbol in each corresponding time unit within the DL duration (k>1), and in the case where the terminal operates in a guard-band mode or a stand-alone mode, signal reception is skipped at a starting portion of the DL duration when the PDSCH is repeatedly received.

Abstract: A method and apparatus for performing transmission in a wireless communication system is provided. A narrowband internet-of-things (NB-IoT) user equipment (UE) transmits a physical uplink shared channel (PUSCH) to a network by using a first resource unit, and transmits an acknowledgement/non-acknowledgement (ACK/NACK) to the network by using a second resource unit. The first resource unit for PUSCH transmission consists of a first number of resource elements (REs) within a first tone in frequency domain and a first time interval in time domain. The second resource unit for ACK/NACK transmission also consists of a second number of REs within a second tone in frequency domain and a second time interval in time domain. The second number is smaller than the first number.

Abstract: According to one embodiment of the present specification, provided is a method for monitoring a downlink channel or a downlink signal by means of a wireless device. The method may comprise the steps of: receiving a power saving signal from a serving cell; and monitoring a subsequent downlink channel or downlink signal based on the reception of the power saving signal. The size of a transmission unit of the power saving signal may be determined based on setup information. The setup information may be received from the serving cell.

Abstract: This specification provides a method for performing early data transmission in a random access procedure in a wireless communication system.
More specifically, the method performed by a user equipment (UE) includes: receiving, from a base station, a control message including first information indicating whether selection for a second transport size (TBS) smaller than a first TBS for message 3 is permitted and second information for the first TBS; transmitting, to the base station, a request for the EDT by using message 1; receiving, from the base station, message 2 including a UL grant for the message 3; determining a repetition number for the message 3 based on the control message and the UL grant; and transmitting the message 3 to the base station by the repetition number.
Therefore, there is an effect that battery consumption of the UE can be reduced.

Abstract: One embodiment of the present invention provides a method for receiving a wake-up signal by a first UE in a wireless communication system, the method comprising the steps of: operating a wake-up receiver during a wake-up signal on-duration by the first UE; and receiving a wake-up signal transmitted by a second UE through the wake-up receiver and then receiving data, wherein information related to the wake-up signal on-duration is commonly signaled to the first UE, which receives the wake-up signal, and the second UE which transmits the wake-up signal. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, the BS or a network.

Abstract: The present disclosure relates to a method and device for receiving a paging signal in a radio resource control (RRC) connected mode. More specifically, the present disclosure relates to a method and a device therefor, the method comprising the steps of: receiving gap configuration information indicating a gap section in a search space; when a first search space related to a data signal in a specific time interval and a second search space related to the paging signal are configured in different narrowbands (NBs), monitoring the second search space in the specific time interval, wherein the first search space is not monitored in the specific time interval on the basis of the gap section; and when the first search space and the second search space are configured in one NB in the specific time interval, monitoring the first search space and the second search space in the specific time interval without applying the gap section.
