Abstract:
There is provided a method for transmitting, by a transmitter, a signal through an unlicensed band channel. The transmitter transmits an initial signal through the unlicensed band channel to preoccupy the unlicensed band channel when the unlicensed band channel is in an idle status. The transmitter includes a first partial subframe transmitted after the initial signal in a frame burst depending to transmission timing of the initial signal. Further, the transmitter transmits the frame burst through the unlicensed band channel.
Abstract:
An apparatus for receiving a signal through an unlicensed band includes: a processor, a memory, and a radio frequency unit, wherein the processor executes a program stored in the memory to perform: receiving a secondary synchronization signal (SSS) in at least one remaining subframe except a subframe 0 or a subframe 5 of a plurality of subframes included in a discovery signal measurement timing configuration (DMTC), and detecting the SSS by using a subframe number of the subframe 0 or the subframe 5.
Abstract:
A method and apparatus of receiving system information of an SeNB, including configuring connection to an MeNB and receiving a RRC Connection Reconfiguration message including the system information of a cell included in a SCG controlled by the SeNB, and a method of sharing frame offset between a MCG controlled by an MeNB and an SCG controlled by an SeNB connected to the MeNB through non-ideal backhaul, including measuring system frame number (SFN) and subframe number (SN) of a cell included in the SCG and sharing the frame offset, which is determined based on the SFN and the SN, with the MeNB or the SeNB are provided.
Abstract:
A communication method of a terminal that may have dual connectivity to a first base station and a second base station is provided. The terminal receives a first Radio Resource Control (RRC) message from the first base station only through a first interface between the first base station and the terminal. The terminal transmits a second RRC message to the first base station only through the first interface.
Abstract:
Provided is an encoding apparatus for integrally encoding and decoding a speech signal and a audio signal, and may include: an input signal analyzer to analyze a characteristic of an input signal; a stereo encoder to down mix the input signal to a mono signal when the input signal is a stereo signal, and to extract stereo sound image information; a frequency band expander to expand a frequency band of the input signal; a sampling rate converter to convert a sampling rate; a speech signal encoder to encode the input signal using a speech encoding module when the input signal is a speech characteristics signal; a audio signal encoder to encode the input signal using a audio encoding module when the input signal is a audio characteristic signal; and a bitstream generator to generate a bitstream.
Abstract:
Provided is a method for transmitting, by a transmitter, a first data having periodicity through a channel of an unlicensed band:The transmitter adjusts at least one of transmission timing of the first data and clear channel assessment (CCA) timing for the channel to occupy the channel. The transmitter determines whether the channel may be occupied by performing a CCA on the channel at the CCA timing. The transmitter transmits the first data through the channel at the transmission timing of the first data, when it is determined that the channel may be occupied.
