Abstract: One embodiment of the present specification provides a method by which user equipment (UE) transmits an uplink signal according to a spectrum emission mask (SEM). The method comprises a step of transmitting the uplink signal on a plurality of carriers when an RF unit of the UE is set to use inter-band carrier aggregation. Here, when the frequency range of a first SEM of a first carrier overlaps the frequency range of a second SEM of a second carrier, any one SEM allowing a higher power spectral density (PSD) can be selected and applied.

Abstract: One embodiment of the present specification discloses a receiving method. The receiving method comprises the steps of: cancelling interference caused by a cell-specific reference signal (CRS) of a neighboring cell from a bit string received from a serving cell; determining weight to be applied to the bit string; applying the determined weight to the bit string; and decoding the bit string to which the weight is applied. In the step of determining the weight, it is possible to determine the weight to be applied depending on whether or not CRSs collide with each other between the serving cell and the neighboring cell that causes the interference.

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 method, performed by a user equipment (UE), is provided for determining uplink transmission power. A radio frequency (RF) unit is configured to use for an uplink transmission a frequency range of 1980 MHz through 2010 MHz or 1920 MHz through 2010 MHz. The UE receives a value of an additional maximum power reduction (A-MPR) from a serving base station (BS) adjacent to a neighboring BS for serving another UE using for an uplink transmission a frequency range of 2010 MHz through 2025 MHz. An uplink signal is transmitted at an uplink transmission power calculated by using the value of the A-MPR. The value of the A-MPR is 11 dB or 15 dB.
