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: One disclosure of the present specification provides a channel estimation method of a user equipment (UE). The method comprising: acquiring a first channel estimate based on a first reference signal allocated to a first resource element of a subframe received from a base station; and removing a second reference signal from a second resource element of the subframe when an additional reference signal is not required, and decoding a data channel multiplexed in the second resource element using a result of channel estimation of an entire channel performed based on the first channel estimate. The second reference signal and the data channel may be multiplexed in the second resource element.

Abstract: A disclosure of the present specification provides a method for performing measurements. The method may performed by a user equipment (UE) comprise: performing, by the UE, measurements; based on that (i) the measurements are for measuring a cross link interference (CLI) and (ii) that the measurements are performed on a sounding reference signal (SRS) from a neighboring UE in a neighboring cell, adjusting a time error between a downlink reference timing in a serving cell and a SRS arrival timing from the neighboring UE. The adjustment is performed based on offset.

Abstract: Provided is a method for transmitting and receiving a signal by a terminal supporting dual-connectivity between evolved universal terrestrial radio access (E-UTRA) and new radio (NR). In the method, when the E-UTRA uses at least one of E-UTRA operating bands 1, 3, 5, and 7, when the NR uses one of NR operating bands n77, n78, and n79, when an uplink center frequency of a first operating band among the E-UTRA operating bands and the NR operating bands is a first value, and when a downlink center frequency of the first operating band is a second value, a predetermined maximum sensitivity degradation (MSD) is applied to reference sensitivity used for reception of the downlink signal.

Abstract: One disclosure of the present specification provides a method for simultaneously transmitting, by user equipment (UE), a cellular uplink signal and a proximity service (ProSe) signal. The method may comprise a step of determining the total transmission power PCMAX of the cellular uplink signal and the ProSe signal. Here, the total transmission power PCMAX may satisfy PCMAX_L≤PCMAX≤PCMAX_H. At this time, PCMAX_L may be a lower limit value and PCMAX_H may be an upper limit value. The cellular uplink signal is transmitted in a subframe n, the ProSe signal is transmitted in a subframe m, and subframe n may be considered as a reference subframe if subframe n and subframe m are time asynchronous.

Abstract: One disclosure of the present specification provides a method for performing measurement based on discovery signals. The method may comprise the steps of: receiving, from cells, discovery signals based on cell-specific reference signals (CRSs); and performing measurement based on the CRS-based discovery signals for a predetermined measurement period. If a measurement bandwidth is six resource blocks (RBs), the predetermined measurement period can be determined by 5*the measurement occasion periodicity of the discovery signals. If the measurement bandwidth is 25 resource blocks (RBs), the predetermined measurement period can be determined by 3*the measurement occasion periodicity of the discovery signals. Also, the discovery signals can be received for a discovery signal occasion duration defined by N consecutive subframes.

Abstract: A disclosure of the present specification provides a method for performing measurement in a wireless device having a plurality of radio frequency (RF) chains for supporting aggregation of multiple carriers. The method may comprise the steps of: receiving, from a base station, information including measurement configuration (MeasConfig) information that includes a measurement gap (MG) for performing inter-frequency measurement; when the number of the received measurement gaps is one, determining, among the multiple carriers, a carrier corresponding to the RF chain to which the one measurement gap is to be applied; and transmitting, to the base station, a measurement report including the result of performing inter-frequency measurement by applying the measurement gap to the RF chain for the determined carrier. When the number of the received measurement gaps is one, the measurement report may include an indication of the carrier to which the measurement gap has been applied.
