    Abstract: One general aspect of the present disclosure includes a device configured to operate in a wireless system. The device including: a transceiver configured with a plurality of E-UTRA operating bands; and a processor operably connectable to the transceiver. The processer may be configured to: control the transceiver to transmit an uplink signal via at least two bands among the plurality of E-UTRA operating bands; and control the transceiver to receive a downlink signal via three bands among the plurality of E-UTRA operating bands, wherein pre-configured MSD value is applied to a reference sensitivity for receiving the downlink signal based on the E-UTRA operating band 2.

    Abstract: A disclosure of the present specification provides a method for performing measurement by a wireless communication device. The method may comprise the steps of: receiving a synchronization signal (SS)/physical broadcast channel (PBCH) block (SSB) from a serving cell in a first period by using a first number of reception beams; performing measurement on the basis of the received SSB; and receiving downlink data from the serving cell in a second period by using a second number of reception beams, wherein the first period and the second period are included in an SS-based measurement timing configuration (SMTC) window duration, and the downlink data is considered not to be transmitted during a third period in which the number of the reception beams is changed from the first number to the second number or is changed from the second number to the first number.

    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: 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.
