Abstract: The present invention relates to a wireless access system that supports an unlicensed band, and provides various methods for adjusting a contention window size and devices for supporting the same. As an embodiment of the present invention, a method for adjusting a contention window size (CWS) in a wireless access system supporting an unlicensed band may comprise the steps of: performing a channel access procedure; when, as a result of performing the channel access procedure, it is determined that a serving cell (Scell) in the unlicensed band is in an idle state, transmitting a transmission burst including a downlink signal; receiving HARQ-ACK information corresponding to the transmission burst; and adjusting the CWS on the basis of the HARQ-ACK information corresponding to the first subframe of the transmission burst.

Abstract: A method for receiving a signal by an apparatus in a wireless communication system is discussed. The method includes receiving, in a first time resource within a second time resource configured as 14 number of symbols, a physical channel carrying downlink control information within resource element groups (REGs), and receiving a physical downlink shared channel based on the downlink control information. Further, the REGs are indexed starting from a symbol included in the first time resource, and a starting boundary of the first time resource is determined independently from a starting boundary of the second time resource.

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: A disclosure of the present specification provides a random access method for an unlicensed band. The method comprises the steps of: transmitting, by a user equipment (UE), a random access preamble in a first cell of the unlicensed band; and receiving, by the UE, a random access response in a second cell, wherein the second cell may be a first cell, a cell of the unlicensed band, included in a cell group to which the first cell belongs, or a cell of the unlicensed band, included in a timing advance group (TAG) within the cell group, to which the first cell belongs.

Abstract: According to an embodiment of the present invention, a user equipment (UE) may receive one or more physical downlink control channels (PDCCHs) each carrying downlink control information (DCI) including a field indicating a transmitting configuration index (TCI) state, and receive, based the one or more PDCCHs, one or more of a plurality of physical downlink shared channels (PDSCHs), wherein the plurality of PDSCHs may carry a same transport block (TB) in a plurality of TCI states, respectively, and the UE can determine, for each TCI state, whether a hybrid automatic repeat request (HARQ) operation is enabled or disabled, and transmits HARQ-acknowledgement (ACK) information for the same TB through a physical uplink control channel (PUCCH) associated with an HARQ operation-enabled TCI state.

Abstract: Disclosed are a method for mutually transmitting or receiving a downlink signal by a terminal and a base station in a wireless communication system and a device for supporting the same. More particularly, disclosed are a method for transmitting or receiving a signal and a device for supporting the same, in which when a subcarrier interval rapidly changes in a continuous time area, such as a multi-media broadcast multicast service single frequency network (MBSFN), a receiver can more reliably receive a signal (for example: a data signal) transmitted in a resource area where the subcarrier interval has rapidly changed.

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.
