摘要： A method and apparatus for deriving an intra-prediction mode are disclosed. At least one embodiment of the present disclosure provides a method of deriving an intra-prediction mode, including (i) obtaining, based on reference line information indicating any one of a plurality of reference lines, most probable mode (MPM) information indicating whether an intra-prediction mode of a current block is included in an MPM list lacking a planar mode, (ii) determining, based on the reference line information and the MPM information, planar information indicating whether the intra-prediction mode of the current block is the planar mode, and (iii) deriving the intra-prediction mode of the current block by using the planar information.

摘要： A wireless communication terminal is disclosed. The wireless communication terminal includes a transceiver configured to transmit/receive a wireless signal; and a processor configured to control an operation of the wireless communication terminal. The transceiver transmits a training signal to a base wireless communication terminal based on a sub-frequency band allocated from the base wireless communication terminal, and transmits data to the base wireless communication terminal through the sub-frequency band allocated from the base wireless communication terminal. The training signal is used, by the base wireless communication terminal, for receiving the data from the wireless communication terminal.
