Abstract: Provided is a method for performing measurement by a user equipment (UE). The method may include receiving, by the UE, configuration information on a measurement gap. The UE may be configured with a dual connectivity (DC) to an evolved universal terrestrial radio access (E-UTRA) cell and a new radio access technology (NR) cell. The configuration information on the measurement gap may include a measurement gap length (MGL). The MGL may include one of 3 ms, 4 ms and 6 ms. The method may include determining a total number of slots to be interrupted during the MGL, and performing the measurement during the MGL. The total number of slots to be interrupted may be determined based on a subcarrier spacing (SCS) of the NR cell and the MGL.

Abstract: One embodiment of the present invention provides a method for a wireless device determining transmission power. The method may comprise the steps of: when asynchronous dual transmissions for vehicle-to-everything (V2X) and a cellular uplink are set, and when a subframe p for cellular uplink transmission and a subframe q for V2X transmission mutually overlap, determining whether the subframe p for cellular uplink transmission precedes the subframe q for V2X transmission; and on the basis of the decision, determining a reference subframe from among the subframe p and the subframe q. Here, the reference subframe may be used for determining the lower limit of a transmission power.

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.
