Abstract: 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.

Abstract: Provided is a wireless communication terminal that communicates wirelessly. The wireless communication terminal includes a transceiver, and a processor. The processor is configured to receive an Aggregate-MAC Protocol Data Unit (A-MPDU) from an originator using the transceiver, and when receiving all MPDUs included in the A-MPDU, transmit to the originator a block ACK (BA) frame signaling that all MPDUs included in the A-MPDU are received without a bitmap indicating whether each MPDU included in the A-MPDU is received.

Abstract: Disclosed is a wireless communication terminal. The wireless communication terminal includes a transceiver transmitting/receiving a wireless signal; and a processor controlling an operation of the wireless communication terminal. The transceiver receives a first frame including information on a manner for accessing, by a plurality of wireless communication terminals including the wireless communication terminal, a base wireless communication terminal. The processor acquires a manner for accessing the base wireless communication terminal on a basis of the first frame. The transceiver accesses the base communication terminal on a basis of the manner for accessing the base wireless communication terminal. The base wireless communication terminal is any one communication terminal different from the plurality of wireless communication terminals.

Abstract: A wireless communication terminal communicating wirelessly with a base wireless communication terminal and unassociated with the base wireless communication terminal is disclosed. The wireless communication terminal includes: a transceiver; and a processor configured to receive, by using the transceiver, a multi-station Block ACK frame which indicates whether at least one of MAC frames transmitted from at least one of wireless communication terminals is received by using a first field of the multi-station Block ACK frame for indicating an association identifier corresponding to an association of each of the at least one of wireless communication terminals and the base wireless communication terminal, from the base wireless communication terminal, and determine whether a MAC frame transmitted from the wireless communication terminal is received by the base wireless communication terminal based on whether a second field of the multi-station Block ACK frame includes a MAC address of the wireless communication terminal.
