Apparatus and method for beam locking in wireless communication system

An apparatus for a user station in a wireless communication system, the apparatus comprising:nat least one motion recognition sensor configured to measure at least one physical value indicating at least one of a movement and a motion of the user station; anda processor configured tondetermine a direction of a beam used by the user station,set a first direction, which is an absolute direction of the beam, as a reference direction, andif the absolute direction of the beam is changed from the first direction to a second direction, due to movement or motion of the user station, while a relative direction of the beam is maintained, adjust the relative direction of the beam to substantially align the absolute direction of the beam with the first direction, based on a difference between a first physical value corresponding to the first direction and a second physical value corresponding to the second direction.

A method for performing beam locking in a wireless communication system, the method comprising the steps of:ndetermining a direction of a beam used by a user station;setting a first direction, which is an absolute direction of the beam, as a reference direction; andif the absolute direction of the beam is changed from the first direction to a second direction, due to a movement or a motion of the user station, while a relative direction of the beam is maintained, adjusting the relative direction of the beam to substantially align the absolute direction of the beam with the first direction, based on a difference between a first physical value corresponding to the first direction and a second physical value corresponding to the second direction.

An apparatus for a user station in a wireless communication system, the apparatus comprising:nat least one motion recognition sensor configured to measure at least one physical value indicating at least one of a movement and a motion of the user station;a transceiver configured to transmit a control message to a base station, wherein the control message comprises information about the at least one motion recognition sensor and information indicating whether the user station supports beam locking; anda processor configured to adjust a relative direction of a beam to substantially align an absolute direction of the beam with a direction to the base station, if the movement or the motion of the user station is detected.

A method for operating a user station in a wireless communication system, the method comprising:ntransmitting a control message to a base station, wherein the control message comprises information about at least one motion recognition sensor for estimating the first physical value and the second physical value and information indicating whether the user station supports beam locking;detecting a movement or a motion of the user station by using the at least one motion recognition sensor; andadjusting a relative direction of a beam to substantially align an absolute direction of the beam with a direction to the base station.

An article of manufacture for performing beam locking in a wireless communication system, comprising a non-transitory computer readable medium containing one or more programs, which when executed implement the steps of:ndetermining a direction of a beam used by a user station;setting a first direction, which is an absolute direction of the beam, as a reference direction; andif the direction of the beam is changed from the first direction to a second direction, due to a movement or a motion of the user station, while a relative direction of the beam is maintained, adjusting the relative direction of the beam to substantially align the absolute direction of the beam with the first direction, based on a difference between a first physical value corresponding to the first direction and a second physical value corresponding to the second direction.
