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.

Abstract: A method of reducing transmission power. The method according to one embodiment includes calculating a maximum power reduction (MPR) on a maximum output power for transmission with non-contiguous resource allocation in a single component carrier; and transmitting a signal. The MPR is calculated differently depending on a ratio A which is a ratio of a number of simultaneously transmitted resource blocks in a channel bandwidth (NRB_alloc) to a number of aggregated resource blocks in a fully allocated aggregated channel bandwidth (NRB_agg). The MPR is calculated using a first equation when the ratio A is greater than 0 and less than or equal to 0.33. The MPR is calculated using a second equation when the ratio A is greater than 0.33 and less than or equal to 0.77. The MPR is calculated using a third equation when the ratio A is greater than 0.77 and less than or equal to 1.

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.
