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: One disclosure of the present specification provides a method for performing a proximity service (ProSe). The method may be performed by a user equipment (UE) and comprise: performing, by the UE configured with a primary cell (Pcell) and a secondary cell (Scell), a switching between the ProSe and a cellular service with at least one of the Pcell and the Scell; transceiving a ProSe discovery signal with at least one or more adjacent UEs after performing a switching from the cellular service to the ProSe service; and transceiving a signal with the at least one of the Pcell and the Scell after performing a switching from the ProSe service to the cellular service. Here, the UE is allowed an interruption of up to one subframe that is N subframes before and after an uplink (UL) subframe configured for transmitting the ProSe discovery signal.

Abstract: According to one embodiment of the present invention, provided is a wireless equipment for transmitting an uplink signal through a reduced transmission resource block (RB) in a wireless communication system. The wireless equipment can comprise: a processor; and a radio frequency (RF) unit for transmitting an uplink signal under control of the processor. When the RF unit is set to a predetermined channel bandwidth and a predetermined frequency range and must satisfy a predetermined maximum allowed value of spurious radiation to protect another frequency range, the uplink signal can be transmitted according to a predetermined maximum number of RBs instead of a total number of RBs for the predetermined channel bandwidth.

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.

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.
