Abstract:
The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and an apparatus in which a terminal receives downlink data in a wireless communication system. The method comprises: a step of receiving a control channel signal including resource allocation information through a specific time domain of a subframe having a plurality of time domains; and a step of receiving the downlink data through the downlink data channel resource domain scheduled by the resource allocation information within said specific time domain. In cases where the downlink data channel resource domain is overlapped with a common search space, the downlink data is received through the residual resource domain except the portion overlapped with the common search space from among the downlink data channel resource domain.

A wireless communication system is disclosed. A method for transmitting uplink control information in a wireless communication system supporting carrier aggregation and operating in TDD includes: generating a first HARQ-ACK (hybrid automatic repeat request—acknowledgement) set for a first cell using a value M; generating a second HARQ-ACK set for a second cell using the value M; and transmitting a bit value corresponding to a third HARQ-ACK set including the first HARQ-ACK set and the second HARQ-ACK set in an uplink subframe n, wherein M=max(M1, M2), max(M1, M2) representing a value being equal to or larger than not smaller between M1 and M2, wherein M1 corresponds to the number of downlink subframes corresponding to the uplink subframe n in the first cell, and M2 corresponds to the number of downlink subframes corresponding to the uplink subframe n in the second cell, wherein the first cell and the second cell have different UL-DL configurations.
Abstract:

Abstract:
A method by which a terminal transmits an uplink signal in an unlicensed band, and an apparatus using same are provided. The method receives, from a base station, channel occupancy information through a PDCCH and transmits the uplink signal to the base station through a configured grant uplink access (CUL) type physical uplink shared channel (PUSCH) on the basis of the channel occupancy information. The channel occupancy information indicates which sub-band of a CUL band including a plurality of sub-bands enables the terminal to transmit the CUL type PUSCH within a channel occupancy time (COT) acquired by the base station through a channel access procedure.
Abstract:
Provided are a method by which a terminal monitors a downlink control channel in a wireless communication system, and a device. The method receives a configuration message that notifies of a monitoring occasion for detecting a wake up signal and, if first control channel monitoring for detecting the wake up signal is not required in the at least one monitoring occasion, monitors a second control channel in the next DRX-on section.
Abstract:
The present specification discloses a DRX operation method performed, by a terminal in which a PCell and a SCell are configured, in a wireless communication system. The DRX operation method comprises: receiving DRX configuration information from a base station; monitoring a PDCCH on the PCell based on the DRX configuration information; receiving dormant BWP configuration information from the base station, wherein the dormant BWP configuration information is information about a downlink BWP used as a dormant BWP on the SCell, from among at least one downlink BWP configured for the terminal; receiving, from the base station, DCI for notifying activation of the dormant BWP; and stopping monitoring a second PDCCH in the dormant BWP on the SCell, wherein a BWP inactivity timer is not used based on the activation of the dormant BWP, and the BWP inactivity timer may be a timer for transition to a default BWP.
Abstract:

Abstract:
A UE may: receive a configuration regarding a physical downlink control channel (PDCCH) monitoring occasion (MO) for UL CI reception; receive scheduling information for UL transmission; and perform or skip UL CI monitoring for the UL transmission in the PDCCH MO on the basis of the configuration and the scheduling information. Performing or skipping the UL CI monitoring for the UL transmission in the PDCCH MO may comprise: performing the UL CI monitoring for the UL transmission in the PDCCH MO on the basis of the fact that the UL transmission and a reference resource region that may be instructed by a UL CI received in the PDCCH MO overlap at least in terms of time; and skipping the UL CI monitoring for the UL transmission in the PDCCH MO on the basis of the fact that the reference resource region and the UL transmission do not overlap in terms of time.
