Abstract: The present specification provides a method for receiving data through interference cancellation. The method can comprise the steps of: receiving a transmission signal transmitted by a DMRS-based transmission method; detecting, from the transmission signal, a DMRS-based transmission parameter for an interference cell having caused interference in the transmission signal; estimating an interference channel for the interference cell on the basis of the detected DMRS-based transmission parameter; generating an interference signal for the interference cell on the basis of the estimated interference channel; and cancelling the generated interference signal from the transmission signal so as to restore data transmitted by a serving cell.

Abstract: A disclosure of the present specification provides a method for receiving a sidelink synchronisation signal (SLSS) for proximity service (ProSe). The method may comprise the steps of: receiving an SLSS from a neighbouring ProSe UE; and measuring a reference signal received power (RSRP) of the SLSS during a pre-determined measurement period. The measurement step can be executed assuming that the SLSS transmission from the neighbouring ProSe UE during the measurement period is not abandoned more than once. The measurement period can be extended if the SLSS transmission from the neighbouring ProSe UE is abandoned more than once.

Abstract: According to one embodiment of the present specification, a user terminal is provided. The user terminal can comprise: a tunable antenna capable of adjusting a band; a diplexer connected to the tunable antenna to synthesize and separate sub-carriers; one or more antenna switches connected to the diplexer to synthesize and separate low-band sub-carriers and middle-band and high-band sub-carriers; and a sub-carrier processing unit connected to the one or more antenna switches to synthesize and separate a plurality of low-band sub-carriers, a plurality of middle-band sub-carriers and a plurality of high-band sub-carriers. A low-noise amplifier can be connected to the sub-carrier processing unit in order to prevent an increase in a reception sensitivity loss and a noise index occurring on a reception path of the diplexer, the one or more antenna switches and the sub-carrier processing unit.

Abstract: One embodiment of the present specification provides a method for resource allocation by a serving cell base station, for supporting interference removal. The resource allocation method may comprise the steps of: determining whether or not UE has an interference removal function; and if the UE has the interference removal function, allocating resource blocks (RB) to the UE through a negotiation with an interfering cell with respect to the allocation of the resource blocks (RB). Herein the resource blocks (RB) of the interfering cell, which are co-located with the resource blocks (RB) according to the negotiation, may be allocated to another UE by the interfering cell without being divided.
