A method of a transmitting terminal may include: determining a beam candidate set including two or more beams usable for sidelink communication with a receiving terminal from among a plurality of beams that can be beam-formed; determining a resource set for each beam within the beam candidate set through resource sensing, such that the resource set has candidate resources equal to or greater than a predetermined number of candidate resources; selecting a beam and a resource to be used for sidelink communication with the receiving terminal based on the beam candidate set and the resource set; and transmitting sidelink data to the receiving terminal using the selected beam and the selected resource.

Method and apparatus for selecting resources for beam-based sidelink communication and sidelink communication using the same

Various exemplary embodiments of the present invention relate to a base station apparatus including: an information receiving module which receives information used for scheduling from a plurality of terminals corresponding to the base station apparatus; and a scheduler which generates resource allocation information for one shared FA among a plurality of FAs which is available in the base station apparatus based on the received information and applies the generated resource allocation information to at least one other shared FA.

Method of sharing resource allocation information and base station apparatus therefor

The present invention relates to a data processing method and system for checking an interactive communication sequence (ICS) relating to a plurality of users in a communication record by using a variable time window, and checking an interactive communication sequence pattern (ICSP) that is a frequently generated interactive communication sequence from among the checked interactive communication sequences. The data processing method includes: (a) storing an inverse pair in a communication record in an interactive communication sequence set or a candidate set that is a set of inverse pairs that can be part of the interactive communication sequence; (b) generating an interactive communication sequence having a length other than 1 by combining interactive communication sequences included in the interactive communication sequence set; and (c) generating an interactive communication sequence having a length other than 1 by combining the inverse pair included in the candidate set and one of the interactive communication sequence included in the interactive communication sequence set of (a) and the interactive communication sequence generated in (b).

Method for processing data to check an interactive communication sequence and system thereof

The present invention relates to a harmonic-noise speech coder and coding algorithm of the mixed signal of voiced/unvoiced sound using harmonic model. The harmonic-noise speech coder comprises a noise spectral estimating means for coding the noise component by predicting the spectral by LPC analysis method after separating the noise, which is unvoiced sound component from the inputted LPC residual signal using cepstrum. And more improved speech quality can be obtained by analyzing noise effectively using the noise spectral model predicted through cepstrum-LPC analysis method of the mixed signal of voiced/unvoiced sound to the existing harmonic model and then coding the signal.

Harmonic-noise speech coding algorithm and coder using cepstrum analysis method

A time-separated speech coder that codes a transitional signal of voiced/unvoiced sound through harmonic speech coding, the coder including a transitional excitation signal analyzer/synthesizer for coding the transitional signal by extracting the harmonic model parameters of both transitional analyzers after detecting a transitional point and generating sinusoidal waveforms according to a variable transitional point separating both transitional analyzers. By the transitional point at which energy varies abruptly and the time-separated coding based on the transitional point, more improved speech quality than in the general harmonic speech coder can be obtained using the time-separated speech coder by increasing the representation capability of the transitional signal with large energy variation, after adapting it to the variable transitional point.
