Abstract:
A disclosure of the present specification provides a method for transmitting an uplink signal by a user equipment. The method may comprise the steps of: receiving a network signal for restricting a transmission power, wherein, when an uplink signal is transmitted through an uplink carrier wave in an uplink band that partially overlaps a mobile satellite service (MSS) band, the network signal is received in the case in which the uplink signal may provide interference to a personal handyphone system (PHS) band; determining a transmission power by applying additional maximum power reduction (A-MPR) on the basis of the received network signal; and transmitting the uplink signal through the uplink carrier wave according to the determined transmission power.

The present disclosure provides a method of measuring a small cell based on a discovery signal. The method may include the step of receiving a discovery signal measurement timing configuration (DMTC) for a neighboring small cell. In this step, the DMTC may include DMTC periodicity information and information on a discovery signal occasion section. The information on the discovery signal occasion section may indicate one or more sub-frames in which the discovery signal occurs. The method may include the step of measuring the neighboring small cell for a measurement gap in the case where the neighboring small cell operates at a frequency that is different from a serving cell.

Abstract:
A method and a base station for transmitting information for cell measurements, and a method and a user equipment for performing cell measurements are discussed. The method for transmitting information for cell measurements according to an embodiment includes transmitting, by the base station, information indicating a first time domain measurement resource restriction pattern for measurements of a first cell. The first time domain measurement resource restriction pattern indicates which subframe among subframes corresponding to the first time domain measurement resource restriction pattern is used for the measurements of the first cell. The first time domain measurement resource restriction pattern is configured such that a subset of non-almost blank subframes in an almost blank subframe pattern configured in the first cell is used for the measurements of the first cell. The almost blank subframe pattern indicates which subframes are configured as almost blank subframes or as the non-almost blank subframes.
