A method for transmitting a control signal, performed by a wireless device. The method according to one embodiment includes allocating resource elements (REs) for a control channel; and transmitting the control signal through the Res. Each RE in the REs for the control channel is associated with one out of two antenna ports. The two antenna ports are included in a plurality of antenna ports used for transmitting demodulation reference signals (DM RS).

The present invention relates to a wireless communication system. More specifically, a repeater operation method and apparatus are disclosed. A method for supporting a repeater by a base station in a wireless communication system according to an embodiment of the present invention may include the steps of: determining whether a relay communication about a target user equipment (UE) is required; and transmitting the repeater activation message to one or more repeater candidates. The activation message may include one or more parameters among an activation cycle, location, or a signal strength threshold for the one or more repeater candidates. A repeater satisfying the condition given by the one or more parameters from among the one or more repeater candidates can be activated as a repeater for the target UE.

A method comprises a preprocessing step consisting, in the gateway station, in pre-segmenting the data as a function of the carrier frequency which is dedicated to them on the downlink DL, in reassembling and in encapsulating the pre-segmented data in successive basic frames DL BB-Frames, that can be transmitted over the downlink, each basic frame DL BB-Frame of the downlink being encapsulated by addition of a specific transport header DL BB-TH on the downlink and a data field, and a step consisting, in the gateway station, in incorporating the different basic frames DL BB-Frames of the downlink in the data field of the different basic frames UL BB-Frames of the uplink.

Methods and apparatuses are disclosed for maritime communication. According to an embodiment, a network comprises a first server and a first base station at a first maritime vessel, and one or more second servers and one or more second base stations at one or more respective second maritime vessels. In response to a trigger event indicating that interference between at least two base stations of the first base station and the one or more second base stations is serious, the first server obtains a contribution value of the first base station to the network determined by the second server. The first server determines whether the first base station needs power reduction or power off based at least on the obtained contribution value. When determining that the first base station needs power reduction or power off, the first server sends an instruction for power reduction or power off to the first base station.
