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.-

Abstract: A data relay method includes receiving a relay request from a BS, and when the relay request is accepted, relaying data between the BS and at least one external terminal, or the data relay method includes determining relaying between a first terminal among a plurality of terminals, and other remaining terminals excluding the first terminal among the plurality of terminals, and relaying data between the first terminal and the other remaining terminals.
Abstract translation: 数据中继方法包括从BS接收中继请求，当接收到中继请求时，BS与至少一个外部终端之间的中继数据或数据中继方法包括：确定多个终端中的第一终端之间的中继 ，以及在多个终端之中除了第一终端之外的其他剩余终端，并且在第一终端和其他剩余终端之间中继数据。

Abstract: Disclosed are a base station and a channel access method performing a channel access in a unlicensed band. The channel access method includes: performing channel sensing at least once on a channel of the unlicensed band in a channel sensing period of a frame; and broadcasting a reservation signal for the channel when the channel is empty.

Abstract: A method and terminal for performing beamforming. The beamforming method of a terminal includes acquiring a beamforming signal, calculating a beamforming coefficient to correspond to locations of a transmitter and a receiver, based on the beamforming signal, acquiring sensor information of the terminal, estimating a channel parameter based on the sensor information, and determining a final beamforming coefficient based on the beamforming coefficient and the channel parameter.
