    摘要: Provided are a method and apparatus for, in a video encoding and decoding procedure, selecting a candidate motion vector of a current block from a motion vector candidate list of the current block, determining a motion vector of the current block by performing a motion search based on the candidate motion vector, performing motion compensation by using the determined motion vector of the current block, and applying local luminance compensation to the current block based on whether the local luminance compensation is to be applied to the current block, wherein a cost function used for performing the motion search is determined based on whether the local luminance compensation is to be applied to the current block.

    摘要: In video encoding and decoding processes, in order to add a motion vector when the motion vector is insufficient in a motion vector prediction value candidate list of a current block, provided are method and apparatus for determining a base motion vector in a motion vector candidate list, determining the motion vector candidate list including an additional motion vector candidate determined based on the determined base motion vector and predetermined offset information, and determining a motion vector of the current block by using an additional motion vector candidate determined in the motion vector candidate list.

    摘要: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for a mobile access point P) in a Wireless environment may comprise the steps of: receiving, from a station, a message indicating that uplink traffic exists, through a proximity communication path; switching a hotspot from an idle mode to an active mode, in response to the received message, transmitting, to the station, a response message to the received message through the proximity communication path, in response to the switching to the active mode; and receiving, from the station, the uplink traffic through a path on the hotspot.
