Abstract: Disclosed herein is a method for transmitting, by a terminal, a sounding reference signal (SRS). The terminal receives a grant for uplink multiple subframes from a base station. The terminal determines a first subframe for an SRS transmission of the terminal among the uplink multiple subframes on the basis of SRS transmission position information received from the base station. Further, the terminal transmits the SRS in the first subframe.

Abstract: An operating method of a communication node in a network supporting licensed and unlicensed bands is disclosed. An operation method of a base station comprises the steps of: transmitting a PDSCH to a UE in an unlicensed band; receiving an HARQ response to the PDSCH from the UE; and determining a size of a CW on the basis of a proportion of NACKs in HARQ responses. Therefore, a performance of a communication network can be improved.

Abstract: A method and an apparatus for transmitting and receiving a signal in a communication network are disclosed. A method for operating UE supporting an unlicensed band comprises the steps of: receiving from a base station DMTC-related information including DMTC cycle and DMTC offset; checking DMTC section to which DRS is transmitted based on the DMTC-related information; and receiving from the base station the DRS using sub-frames apart from a sub-frame corresponding to the DRS cycle within the DMTC section. As a result, the performance of a communication network can be improved.

Abstract: The present disclosure relate to a spectrum sensing method and a spectrum sensing device. The spectrum sensing method includes: (a) sampling a received signal: (b) calculating a first operation value relating to a strength of the received signal based on the sampled signal; (c) searching for a first frequency band having the largest correlation with an input signal based on the sampled signal; (d) calculating a first residual component signal by removing a signal component in the first frequency band from the received signal; (e) calculating a second operation value relating to a strength of the first residual component signal; and (f) determining whether the frequency band occupied in the received signal is present based on a relative value of the first operation value and the second operation value.
