Abstract:
One embodiment of the present specification relates to a method for reducing transmission power. The method for reducing transmission power can comprise the steps of: determining whether set carrier aggregation (CA) corresponds to intra-band non-contiguous CA when the CA is set; determining transmission power by applying maximum power reduction (MPR) when the set CA corresponds to intra-band non-contiguous CA; and reducing power by applying additional MPR to the determined transmission power in order to protect adjacent bands when non-contiguous carriers belong to a specific band.
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 of providing, by a UE served in a small-scale cell, information about surrounding UEs in a wireless communication system in which a macro cell and the small-scale cell coexist. The method can include the steps of: carrying out a handover from the macro cell to the small-scale cell; after completion of the handover, overhearing a signal transmitted by the UE; measuring signal intensities of the surrounding UEs; and, if the signal intensities meet predefined conditions, delivering information about the surrounding UEs to the small-scale cell.
Abstract:
A method of reducing transmission power. The method is performed by a user equipment and includes calculating a maximum power reduction (MPR) on maximum output power for transmission with non-contiguous resource allocation in a single component carrier; and transmitting a signal based on the MPR. The MPR is determined according to the following equation: MPR=CEIL {MA, 0.5}, the CEIL being a function of rounding up by 0.5. The MA is determined according to the following equations: MA=(8.0−10.12*A) when 0

Disclosed in the present invention are a method for estimating an almost blank subframe (ABS) zone in a wireless access system in which a macro cell and a pico cell coexist, and an apparatus for same. More specifically, the present invention comprises the steps of measuring reference signal received power (RSRP) by using a cell-specific reference signal which is inserted into a subframe of the macro cell, and determining whether the format of the subframe is a multicast broadcast single frequency network (MBSFN) ABS by comparing an RSRP measurement value from a zeroth orthogonal frequency division multiplexing (OFDM) symbol of the subframe, and an RSRP measurement value from a symbol that is not the zeroth OFDM symbol.

One embodiment disclosed in the present specification provides a method for a vehicle to everything (V2X) communication, comprising: determining position of at least one frequency for at least one synchronization signal block (SSB), wherein the position of the at least one frequency is determined based on a channel raster for new radio (NR) V2X, wherein the channel raster for the NR V2X is determined based on a first frequency shift of −5 kHz or 5 kHz.
Abstract:
Provided in one embodiment of the present specification is a method for switching a bandwidth part (BWP) for sidelink communication. The method can comprise the steps of: receiving information about a bandwidth part (BWP) switching timing from a base station; and switching a BWP on the basis of the information about the BWP switching timing. The information about the BWP switching timing can include information about the point of time at which the BWP switching should be started after the information has been received. The information about the BWP switching timing can be received through downlink control information (DCI) or a radio resource control (RRC) signal.
