Abstract: Disclosed is a method for transmitting and receiving a channel state information (CSI)-reference signal (RS) in a wireless communication system.
Specifically, the method performed by a base station may include: configuring control information indicating that an antenna port for all CSI-RS resources included in a CSI-RS resource set is same, wherein the CSI-RS resource set is used for tracking at least one of a time or a frequency; transmitting the configured control information to a user equipment (UE); and transmitting the CSI-RS to the UE through all the CSI-RS resources.
In doing so, the UE is capable of performing time/frequency tracking more precisely.

Abstract: The present disclosure provides a method for reporting channel state information (CSI) in a wireless communication system. Specifically, a method for reporting, by a user equipment (UE), channel state information (CSI) in a wireless communication system includes: receiving, from a base station, control information related to a configuration of a channel state information reference signal (CSI-RS) resource, wherein the control information includes CDM type information representing a type of code division multiplexing (CDM) applied to the CSI-RS resource; receiving, from the base station, an X-port CSI-RS on one or more component CSI-RS resource element (RE) patterns; and reporting, to the base station, the CSI based on the received X-port CSI-RS. Accordingly, the present disclosure can flexibly provide CSI-RS resource locations.

Abstract: In the present invention, a part of a first demodulation reference signal sequence generated on the basis of a basic subcarrier interval (hereinafter, a first subcarrier interval) is used for a second subcarrier interval which is K times the first subcarrier interval. Values selected one for every K from among values constituting the first demodulation reference signal sequence may be used as values constituting a second demodulation reference signal sequence for the second subcarrier interval.

Abstract: The present invention provides a method for a terminal and a base station including multiple TRPs to transmit/receive signals, and a device therefor. More particularly, the present invention provides a method whereby, if one or more base stations are present, and multiple TRPs are present in each of the base stations, a TRP for signal transmission/reception by a terminal and a base station is selected by using an uplink signal transmitted by the terminal, and a signal is transmitted/received based on the TRP. The present invention also provides a device for the method.

Abstract: Disclosed are a method for transmitting and receiving channel state information in a wireless communication system and an apparatus therefor. Specifically, a method for transmitting, by a terminal, channel state information (CSI) in a wireless communication system comprises the steps of: receiving a CSI process setting from a base station; and reporting, to the base station, CSI corresponding to a CSI process set by the CSI process setting, wherein when the CSI process is set to a beamformed CSI-reference signal (CSI-RS) type, and the CSI process is associated with a single CSI-RS resource, a codebook used for deriving the CSI may be indicated by the CSI process setting.

Abstract: The disclosure of the present invention proposes a method for connecting to a base station. The method may be performed by a user equipment (UE) and comprise: receiving information on a UE-specific bandwidth of a first cell. Here, the UE-specific bandwidth of the first cell is variable based on a bandwidth of a second cell using long term evaluation (LTE) radio access technology (RAT). The information on the UE-specific bandwidth may indicate a bandwidth between a bandwidth between a minimum bandwidth and a maximum bandwidth.

Abstract: Disclosed are methods for transmission and reception of downlink control information between a base station and a terminal, and devices for supporting same. Disclosed more particularly are: methods whereby a base station transmits downlink control information by means of an analogue beam independently determined for every one or more symbols (e.g., a unit of one or more symbols) and, in response to the base station, a terminal receives, by means of a serving beam of the terminal, the downlink control information transmitted by means of the analogue beam, which corresponds to the serving beam; and devices for supporting same.

Abstract: A method for transmitting and receiving a Reference Signal in a wireless communication system performed by a UE is disclosed. According to the present invention, a UE receives, from a base station, Downlink Control Information and receives a Demodulation Reference Signal (DMRS) through a plurality of antenna ports based on the Downlink Control Information and downlink data.
The UE demodulates the downlink data based on the DMRS, and the downlink data is received in a same symbol as the DMRS or in different symbols with each other based on a number of symbols related to the downlink data.

Abstract: The present invention discloses a method of transmitting an SSS (secondary synchronization signal), which is transmitted by a base station, in a wireless communication system. The method includes the steps of determining a first shift based on a first and a second cell identifiers for identifying a cell, and determining a second shift index based on the first cell identifier and transmitting the SSS using a first sequence which is generated based on the first shift index and a second sequence which is generated based on the second shift index. In this case, the first shift index can be determined as K times a value determined based on the first and second cell identifiers, where K is an integer equal to or greater than 3.
