    Abstract: The present invention relates to a method and terminal for detecting a physical hybrid-ARQ indicator channel (PHICH) in a wireless access system that supports enhanced inter-cell interference coordination. In particular, the method includes: determining whether the PHICH exists in only a 0th orthogonal frequency division multiplexing (OFDM) symbol if a subframe transmitted by a neighboring base station is an almost blanked subframe (ABS); determining whether a common reference signal (CRS) of the neighboring base station collides with a CRS of a serving base station if the PHICH exists outside of the 0th OFDM symbol; determining whether CRS power of the neighboring base station does not collide with the CRS of the serving base station; and determining whether an acknowledgement/negative-acknowledgement (ACK/Negative-ACK) is detected by replacing a symbol of the PHICH, overlapped with the CRS power of the neighboring base station is greater than the preset threshold.

    Abstract: A disclosure of the present specification provides a method for measuring an interference from a neighboring device. The method may performed by a device and comprise: measuring, by the device, an interference based on a reference signal from a neighboring device, which is served by a neighboring cell; and transmitting, by the device, a measurement report to a serving cell, the measurement report including a measured value of the interference. One or more steps of measuring the interference and transmitting the measurement report may be performed based on configuration information. The configuration information includes one or more of start information, end information, a timer or a threshold.

    Abstract: A disclosure of the present specification provides a user equipment (UE) supporting a Dual Connectivity (DC) with Evolved Universal Terrestrial Radio Access (E-UTRA) and New Radio (NR). The UE may include a transceiver configured with the DC and configured to transmit an uplink signal and receive a downlink signal; and a processor configured to control the transceiver. Wherein based on (i) that the E-UTRA includes at least E-UTRA operation band 41, (ii) that the NR includes at least NR operation band 41, and (iii) that a band to be protected is a first band, the transceiver may be configured with a predetermined maximum level of a spurious emission.
