摘要： A method for stably operating an FDR mode by a terminal in a wireless communication system supporting the full-duplex radio (FDR) mode comprises the steps of: if a residual self-interference signal is changed to a predetermined threshold or higher in a terminal, transmitting information about the changed residual self-interference signal to a base station; and receiving from the base station a downlink signal on the basis of a modulation and coding scheme (MCS) level that corresponds to the information about the changed residual self-interference signal.

摘要： Provided is a node unit which is branch-connected to another communication node via a transport medium, the node unit comprising: a delay measurement unit which transmits a test signal for measuring a delay to an adjacent node unit of the branch-connected upper stage via the transport medium and detects a loopback signal to which the test signal is looped back via the adjacent node unit of the upper stage, thereby measuring an upper stage transmission delay between the adjacent node unit of the upper stage and the node unit; a delay summation unit which, when an adjacent node unit of the branch-connected lower stage exists, receives a lower stage transmission delay transmitted from the adjacent node unit of the lower stage, and calculates a summed transmission delay by summing the upper stage transmission delay and the lower stage transmission delay; and a control unit which transmits the summed transmission delay to the adjacent node unit of the upper stage.

摘要： A radio frequency (RF) circuitry includes a device that taps a transmission line and picks up some of electromagnetic signals traveling in both directions. The RF circuitry includes a first detector, a second detector, a third detector, and a processor. The first detector measures a power of a first portion of the tapped electromagnetic signal travelling in one direction. The second detector measures a power of a first portion of the tapped electromagnetic signal travelling in the other direction. The third detector measures a power of a combined signal which includes a second portion of the tapped electromagnetic signal travelling in the one direction and a second portion of the tapped electromagnetic signal travelling in the other direction. The processor determines, based on outputs from the detectors, a relative magnitude and a relative phase of the electromagnetic signals.

摘要： A method of determining reserved tones to be used for reduction of a peak to average power ratio (PAPR) of a signal includes: randomly selecting carrier indices for the reserved tones and generating a kernel signal based on the randomly selected carrier indices; calculating a comparison reference average value of the kernel signal, comparing the calculated comparison reference average value with a prestored comparison reference average value, and preliminarily determining carrier indices of the reserved tones based on the comparison; randomly re-arranging an order of the preliminarily determined carrier indices of the reserved tones; and calculating the comparison reference average value while changing each of the re-arranged indices of the reserved tones, and finally determining carrier indices for which the calculated comparison reference average value becomes the smallest value as carrier indices of the reserved tones.

摘要： A method and a base station for phase compensation in beamforming in a multi-antenna Time Division Duplex (TDD) communication network. In a first transmission mode, the base station estimates a first phase shift between a first antenna port and a reference antenna port in uplink based on a measurement of a first Sounding Reference Signal (SRS). Then the base station estimates in the first transmission mode a second phase shift between the first antenna port and the reference antenna port in downlink based on a Channel State Information (CSI) feedback from a User Equipment (UE), and calculates a parameter indicative of a difference between the first phase shift and the second phase shift.
