Method and apparatus for handover in wireless communication system using beamforming

Abstract: An apparatus and a method for a handover in a communication system using beamforming are provided. The method includes the operations of receiving handover information from a serving base station, measuring, on the basis of beam scanning, a first reference signal transmitted from the serving base station and a second reference signal transmitted from a target base station, if the result of the measurement satisfies handover conditions, transmitting the result of the measurement to the serving base station, and receiving, on the basis of the handover information, a handover permission message from the target base station.

Apparatus and method for providing service in vehicle to everything communication system

Abstract: The present invention relates to a 5th-generation (5G) or pre-5G communication system provided to support a higher data transmission rate than 4th-generation (4G) communication system such as long term evolution (LTE). The method of, by a first device, providing service in a vehicle-to-everything (V2X) communication system includes: a step of transmitting a first message related to the service; a step of receiving a second message representing that the second device accesses an area related to the service from the second device; and a step of transmitting a third message confirming that the second device accesses the area to the second device.

Method and apparatus for handover in a wireless communication system using beam forming

Abstract: The present invention relates to a method for handover in a wireless communication system using beam forming including: a step of receiving information for handover from a serving base station; a step of measuring a first reference signal transmitted from the serving base station and a second reference signal transmitted from a target base station based on beam scanning; a step of transmitting a measurement result to the serving base station when the measurement result satisfies the handover condition; and a step of receiving a handover permission message from the target base station based on the information for handover.

Apparatus and method for transmitting data signals in wireless communication system

Abstract: The present invention relates to a pre-5G or 5G communication system to be provided for supporting higher data rates after a 4G communication system such as LTE. According to an embodiment of the present invention, a method for operating a terminal in a wireless communication system comprises the following steps of: receiving identification information of a band designated for a terminal; receiving resource allocation information on the band and a data signal generated in accordance with an orthogonal frequency division multiple access (OFDMA) technique; and demodulating or decoding the data signal in accordance with the resource allocation information.

Method and apparatus for transmitting and receiving between a station and a neighbor access point in communication system

Abstract: The present invention relates to a 5G or pre-5G communication system which will be provided to support a higher data tranfer rate after a 4G communication system, such as an LTE. A method in which a first apparatus manages resources in a wireless local area network (WLAN) system supporting multiple antennas according to the present invention comprises the steps of: determining the number of resource assignment request messages which are acceptable at a specific time; and transmitting data related to the number of acceptable resource assignment request messages. Each of the resource assignment request messages is acceptable when the first apparatus can assign resources to a second apparatus, which has transmitted the resource assignment request message, at the specific time point.

Method and apparatus for transmitting and receiving message in wireless communication system

Abstract: The present invention relates not only to a 4th-generation (4G) communication system such as long term evolution (LTE) but also to a 5th-generation (5G) or pre-5G communication system to be provided to support a higher data transmission rate. According to the present invention, in a wireless communication system using device to device (D2D) communication, a user equipment (UE) transmits, to a base station, a request message including information indicating that the UE will transmit, through a data channel, a discovery message transmitted in a discovery channel and information on the amount of data related to the discovery message, receives, from the base station, a control message including information on a resource allocated to transmit the discovery message and information indicating that the control message is a message required for the transmission of the discovery message, and transmits the discovery message to a target UE using the data channel on the basis of the control message.

Apparatus and method for operating wireless local area network system

Abstract: The present invention provides an operating method for a wireless local area network (WLAN) system and an apparatus therefor. The method according to the present invention comprises the steps of: when frames requested to be transmitted/being transmissible are determined to be used between a WLAN access point serving a terminal and a base station serving the terminal via a cellular network, the terminal setting a channel occupancy period on the basis of information on a first transmission opportunity section of the WLAN access point obtained from the base station, and monitoring a channel during the set channel occupancy period; and receiving the transmissible frame as a response to the frame requested to be transmitted from the WLAN access point, resetting the channel occupancy period on the basis of information on a second transmission opportunity section contained in the transmissible frame, and transmitting/receiving data to/from the WLAN access point during the reset channel occupancy period.
