摘要： The present invention relates to a method for transmitting an aggregate MPDU and a response frame thereto and a wireless communication terminal using the same, and more particularly, to a wireless communication method and a wireless communication terminal for setting various formats of the aggregate MPDU and the response frame thereto and performing an efficient data communication by using the same. To this end, provided are a wireless communication terminal including: a processor; and a communication unit, wherein the processor receives an aggregate MPDU (A-MPDU) consisting of one or more MAC protocol data units (MPDUs), determines a format of a response frame for the received A-MPDU, and
transmits a response frame of the determined format, wherein the format of the response frame for the A-MPDU is determined based on at least one of the number of traffic IDs (TIDs) soliciting an immediate response in MPDU(s) successfully received in the A-MPDU and MPDU delimiter information of the A-MPDU and a wireless communication method using the same.-

摘要： A video signal processing method comprises the steps of: receiving information for prediction of a current block; determining whether or not a merge mode is applied to the current block on the basis of the information for prediction; when a merge mode is applied to the current block, obtaining a first syntax element indicating whether or not a combined prediction is applied to the current block, wherein the combined prediction indicates a prediction mode that combines inter-prediction and intra-prediction; generating an inter-prediction block and an intra-prediction block of the current block when the first syntax element indicates that the combined prediction is applied to the current block; and generating a combined prediction block of the current block by weighted-summing the inter-prediction block and the intra-prediction block.
