Abstract:
The present application discloses a method for enabling a terminal to report CQI (Channel Quality Indicator) in a wireless communications system. Specifically, the method includes the steps of: receiving the setup information concerning at least one CSI (Channel Status Information Process) through an upper layer; receiving CSI-RS (Channel Status Information-Reference Signal) contained in the setup information from a base station; calculating the CQI by using the CSI-RS under the assumption that the CRS (Cell specific RS) resource contained in a given resource for calculating the CQI is not mapped with data; and reporting the calculated CQI to the base station, wherein the setup information contains the information of the CRS resource.

A method for receiving a radio signal by a receiver including a 2-dimensional antenna array which consists of a plurality of antenna elements in a wireless communication system includes: dividing the plurality of antenna elements into a plurality of groups; determining a group-specific reception beam for each of the plurality of groups; applying the group-specific reception beam to a channel corresponding to each of the plurality of groups to acquire virtual channels respectively corresponding to the plurality of groups; and estimating channels respectively corresponding to the plurality of groups based on reference signals received through the virtual channels.
Abstract:
Disclosed is a video camera, including a body, a camera module installed in the body, and a stand located under the body to support, the stand including a leg bracket coupled to the body, a first leg rotatably coupled to the leg bracket through a first hinge, and a second leg rotatably coupled to an end portion of the first leg through a second hinge, wherein an angle and height of the body are adjustable by adjusting angles of the first and second hinges. Accordingly, the video camera can be installed not only on a floor, but also on a monitor or a wall, thereby being easily installed in various places.
Abstract:
Disclosed herein are a method and a device for transmitting an uplink channel in a wireless communication system. According to the present disclosure, a UE transmits to a base station information associated with uplink transmission supported by the UE and the UE information includes a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive from the base station uplink transmission information including a TPMI for transmitting an uplink channel and transmit to the base station the uplink channel based on the uplink transmission information, and the uplink channel may be transmitted through full transmission power configured by the base station based on a case where the TPMI is included in the subset.
Abstract:
A method for transmitting a physical uplink shred channel (PUSCH) by a terminal in a wireless communication system according to an embodiment of the present specification comprises the steps of: receiving downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH); and transmitting the physical uplink shared channel (PUSCH) on the basis of the DCI. The format of the DCI is DCI format 0_0. On the basis that spatial relation RS information for transmission of the physical uplink shared channel (PUSCH) is not configured, the physical uplink shared channel (PUSCH) is transmitted on the basis of spatial relation quasi-colocation (QCL) RS information of a predefined control resource set (CORESET).
Abstract:
A method in which a UE transmits an uplink signal, based on a codebook, in a wireless communication system includes: receiving downlink control information (DCI) for determining a precoding matrix, which is applied to transmission of the uplink signal, from a base station; determining a precoding matrix that is applied to transmission of the uplink signal from a codebook subset related to transmission of the uplink signal, based on the DCI; and transmitting the uplink signal to the base station, based on the determined precoding matrix, in which, based on that differences of phase values applied to antenna ports for transmitting the uplink signal are changed in all pairs of antenna ports, the codebook subset includes at least one specific precoding matrix for full power transmission.

Abstract:
Disclosed is a method for transmitting an uplink signal in a wireless communication system according to an embodiment of the present disclosure performed by a User Equipment (UE) includes receiving configuration information in relation to transmission power of an uplink signal, determining the transmission power based on the configuration information, and transmitting the uplink signal based on the determined transmission power.
Abstract:
A method for transmitting, by a terminal, an uplink signal in a wireless communication system, according to one embodiment of the present specification, comprises the steps of: receiving an upper layer message related to setting of resource groups for a plurality of panels; receiving a lower layer message related to whether the resource groups are activated; and transmitting an uplink signal on the basis of the lower layer message. The uplink signal is transmitted on the basis of an activated resource group from among the resource groups.
