    Abstract: A method for setting up a mobile backhaul link, performed by a hub in a mobile backhaul system, may comprise: calculating a separation distance between the hub and a mobile backhaul terminal using GPS position information; selecting a beam width and a beam search scheme of at least one beam to be used for setting up the mobile backhaul link according to the separation distance; transmitting ID(s) of the at least one beam to the mobile backhaul terminal through the at least one beam having the beam width according to the beam search scheme; receiving the ID(s) of the at least one beam and a measurement result of the at least one beam from the mobile backhaul terminal; and selecting a first beam having a largest signal strength according to the measurement result, wherein the first beam is used for setting up the mobile backhaul link.

    Abstract: An operation method performed by an access point in a communication system may comprise: transmitting, to a first station, a first frame by using a third communication scheme, the first frame including information on an address of the first station, a first transmission time length, a first reception order, and a first communication scheme to be used for transmitting data to the first station, and information on a second transmission time length, a second reception order, and a second communication scheme to be used for transmitting second data to one or more second stations; receiving, from the first station, a first response frame for the first frame from the first station at a first reception time; and receiving, from the second station, a second response frame for the first frame at a second reception time.

    Abstract: A beam alignment method performed by a first communication node in a communication system may comprise: identifying a position of a first antenna of the first communication node; configuring a first coordinate system based on a physical position and direction of the first antenna, based on information on the position of the first antenna; identifying a position of a second antenna of a second communication node of the communication system; converting information on the position of the second antenna into coordinate information based on the first coordinate system; calculating direction change values of the first antenna based on the information on the position of the second antenna, which is converted based on the first coordinate system; changing a direction of the first antenna based on the direction change values of the first antenna; and updating a beam alignment state between the first and second antennas.
