Abstract: Provided are a method for reporting a power headroom and an apparatus using the same. The apparatus computes and reports a power headroom for a physical uplink shared channel (PUSCH) that is transmitted in a first transmission period of a first band having a first subcarrier interval. The power headroom is computed on the basis of at least one second transmission interval of a second band having a second subcarrier interval which overlaps with the first transmission interval.

Abstract: A method for transmitting channel state information (CSI) by a user equipment in a wireless communication system is discussed. The method includes receiving a transmission burst; measuring the CSI based on the transmission burst; and transmitting the measured CSI, wherein the transmission burst is received in at least a first time resource and a second time resource, wherein the first time resource is configured as a first number of orthogonal frequency divisional multiplexing (OFDM) symbols, wherein the second time resource is configured as a second number of OFDM symbols, wherein the first number is smaller than the second number, and wherein the first time resource is considered to be an invalid time resource for the CSI.

Abstract: A method for generating an SRS sequence by a terminal may comprise the steps of: calculating a first root value for generation of an SRS sequence of a first block among concatenated blocks configured for transmission of an SRS, using a terminal-specific SRS identifier; calculating a second root value for generation of an SRS sequence of a second block on the basis of the calculated first root value and a root offset value; and generating an SRS sequence for transmission of an SRS on the concatenated blocks by applying the first root value to the first block and applying the second root value to the second block.

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 invention provides a method for determining a modulation and coding scheme (MCS) to be applied to data in a wireless communication system, and a device therefor. Specifically, the method may comprise the steps of: reporting, to a base station, channel state information including a first measurement value related to a channel state between a terminal and the base station; receiving at least one downlink reference signal from the base station; calculating a second measurement value related to the channel state by using the received at least one downlink reference signal; when the second measurement values is equal to or smaller than a preconfigured threshold value in comparison with the first measurement value, transmitting, to the base station, a specific uplink signal requesting a change of an MCS designated to downlink data; and receiving the downlink data, to which the changed MCS has been applied, from the base station.

Abstract: Disclosed are a method for transmitting and receiving multicast/broadcast data in a wireless communication system, and an apparatus therefore. Specifically, a method by which a station transmits a reference signal for demodulating multicast/broadcast data in a wireless communication system comprises the steps of: mapping a first reference signal within a control channel region consisting of at least one symbol used for transmission of a control channel within a subframe; and mapping a second reference signal transmitted from multiple cells for demodulating a multicast/broadcast channel within a data channel region excluding the control channel region within at least one resource block which has been allocated for transmission of the multicast/broadcast channel which carries the multicast/broadcast data transmitted from the multiple cells within the subframe, wherein scheduling information for allocating at least one resource block where the multicast/broadcast channel is mapped may be transmitted in the control channel.
