    Abstract: A method by which a terminal transmits feedback information comprises the steps of: determining, in predetermined resource units for receiving the broadcast information in a broadcast resource region, whether broadcast information collides; selecting a first shared resource in a shared resource region corresponding to a first broadcast resource in which the conflict occurs in the broadcast resource region, on the basis of a pre-defined mapping rule of the broadcast resource region and the shared resource region; and transmitting, in the selected first shared resource, feedback information including information on the occurrence of the collision, wherein the broadcast resource region is a resource region, which is defined so as to transmit or receive the broadcast information, and the shared resource region can be determined as a resource region shared between a plurality of terminals. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

    Abstract: Provided are an operating method for an IAB node including a DU and an MT in a wireless communication system, and a device. The method receives first resource direction information about the DU and second resource direction information about the MT, wherein each of the first and second resource direction information indicates the direction of each resource as being downlink, uplink or flexible. The IAB node determines, for a certain resource from among the resources, whether the DU and the MT can operate at the same time on the basis of the direction indicated by the first resource direction information and the direction indicated by the second resource direction information.

    Abstract: A method for reporting channel state information (CSI) in a wireless communication system is disclosed. More specifically, the method performed by a user equipment (UE) includes receiving, from a base station, configuration information related to the channel state information, wherein the configuration information includes a number of a plurality of subbands allocated to the UE; measuring parameter values related to a channel state of one or more subbands of the plurality of subbands based on the configuration information; and reporting, to the base station, channel state information of the one or more subbands including the measured parameter values, wherein a number of the one or more subbands is determined based on a value of a rank indicator (RI).

    Abstract: Disclosed are a codebook-based signal transmission and reception method in a multi-antenna wireless communication system and an apparatus therefor. Specifically, a method for transmitting or receiving a signal on the basis of a codebook by a terminal in a 2-dimensional multi-antenna wireless communication system comprises the steps of: receiving a channel state information reference signal (CSI-RS) through a multi-antenna port from a base station; and reporting channel state information to the base station, wherein the channel state information may include a precoding matrix indicator (PMI) for indicating a precoding matrix, the PMI may include a first PMI for selecting a set of precoding matrixes from the codebook and a second PMI for selecting one precoding matrix from the set of precoding matrixes.
