Abstract: According to an embodiment of the present the UE can be scheduled to simultaneously receive one or more PDSCHs and one or more UE-group common PDSCHs at a same slot. When the simultaneously reception exceeds the UE's simultaneous reception capability, the UE may prioritizes a PDSCH for random access procedure over remaining PDSCHs, determine priorities of the remaining PDSCHs based on priority information in each DCI, and receive ‘M’ PDSCHs including the PDSCH for random access and ‘M−1’ PDSCHs selected from the remaining PDSCHs, where ‘M’ related to the UE's simultaneous reception capability.

Abstract: A method and device for transmitting/receiving a signal in a wireless communication system, according to one embodiment of the present invention, transmits a PUCCH including UCI. With respect to a resource for transmitting the PUCCH, the PUCCH is determined to be associated with a first interlace, among the first interlace and a second interlace, on the basis that: (i) the first interlace, and the second interlace having a higher index than that of the first interlace are configured by means of information on the PUCCH resource; and (ii) the number of physical resource blocks (PRBs) for transmitting the UCI is equal to or less than the number of PRBs of the first interlace.

Abstract: The present disclosure provides a method for transmitting a physical uplink control channel (PUCCH) in a wireless communication system. Specifically, a UE maps a first sequence of first uplink control information (UCI) and a second sequence of second UCI to at least one OFDM symbol of the PUCCH, and transmits the first UCI and the second UCI to a base station through the PUCCH. In this case, the first sequence is sequentially mapped up to a symbol before a last symbol of the at least one OFDM symbol on a frequency axis and mapped at regular intervals of two or more REs (resource elements) in the last symbol. Also, the second sequence is sequentially mapped on the frequency axis between REs of the last symbol to which the first sequence is mapped.

Abstract: A method of transmitting, by a user equipment (UE), uplink control information (UCI) in a wireless communication system includes receiving, from a base station (BS), physical uplink control channel (PUCCH) resource information for the UCI. Further, the UCI is hybrid automatic repeat request (HARQ) feedback information of multiple downlink cells. The method also includes transmitting, to the BS, the UCI on a PUCCH resource. In addition, the PUCCH resource is mapped to multiple resource block (RB) pairs, the multiple RB pairs include RBs included in a first slot and RBs included in a second slot, the RBs included in the first slot are consecutive RBs to each other, and the RBs included in the second slot are consecutive RBs to each other.

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, methods for determining the time when the adjusted contention window size is applied, methods for distinguishing between a collision and a channel error, and devices for supporting the same. As an embodiment of the present invention, a method for adjusting a contention window size in a wireless access system supporting an unlicensed band may comprise the steps of: performing a channel access procedure; when it is determined through the performed channel access procedure that a serving cell (Scell) in the unlicensed band is in an idle state, transmitting a transmission burst including a downlink signal through the unlicensed band; receiving hybrid automatic repeat and request acknowledgment (HARQ-ACK) information corresponding to the transmission burst; and adjusting the CWS using the number of DTX states in the HARQ-ACK information when the transmission burst is scheduled in a self-carrier scheduling scheme.
