Operating method of communication node in network supporting licensed and unlicensed bands
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.
