Abstract:
The present invention relates to a wireless communication system. According to one embodiment of the present invention, a method for transmitting, by a terminal, channel state inµformation (CSI) in a wireless communication system comprises the steps of: subsampling a code book for four antenna ports; and feeding back the CSI on the basis of the subsampled code book, wherein the CSI includes a rank indicator (RI) reported together with a precoding type indicator (PTI), and if the RI is greater than 2, the PTI is set to one.
Abstract:
A method for transmitting a scheduling request (SR) by a terminal in a wireless communication system according to one embodiment of the present specification comprises: a step for receiving setting information related to an SR; and a step for transmitting at least one SR on the basis of the setting information. On the basis of the at least one SR overlapping with a different type of uplink control information (UCI), a UCI bit in which a specific field related to the at least one SR and the different type of UCI are combined is transmitted. On the basis of the at least one SR being related to beam failure recovery (BFR), the specific field indicates the beam failure recovery.

A method for transmitting and receiving HARQ-ACK information in a wireless communication system and a device therefor are disclosed. Specifically, a method of transmitting, by a user equipment (UE), HARQ-ACK information in a wireless communication system, the method comprising receiving configuration information related to a plurality of control resource sets; receiving first downlink control information (DCI) based on the first control resource set and second DCI based on the second control resource set via a physical downlink control channel (PDCCH); and transmitting the HARQ-ACK information based on the determined PUCCH resource, wherein an order of the first DCI and the second DCI is determined based on (i) an index of a monitoring occasion related to the PDCCH, (ii) a cell index, and (iii) an index of each control resource set pool, wherein the PUCCH resource is determined based on a last DCI among the first DCI and the second DCI.
Abstract:
A self-assembly apparatus and method of the present invention for semiconductor light-emitting devices can separate semiconductor light-emitting devices attached to each other by vibrating a fluid during self-assembly to thereby prevent mis-assembly and, for smooth assembly of the semiconductor light emitting devices, generate a flow of the fluid along the movement direction of a magnet. The self-assembly apparatus comprises: a chamber in which a plurality of semiconductor light-emitting devices comprising a magnetic substance and a fluid are accommodated; a transfer unit for transferring, to an assembly location, a substrate on which the semiconductor light-emitting devices are to be assembled; a magnet spaced apart from the chamber to apply a magnetic force to the semiconductor light-emitting devices; a location control unit for controlling a location of the magnet; and a vibration generation unit for generating vibration in the fluid to thereby separate the semiconductor light-emitting devices from each other.
