    摘要: The present invention relates to a method for up-sampling/down-sampling data of a video block in a scalable video data encoding/decoding. The up-sampling method according to the present invention obtains a 2N×2N enlarged block by computing a converting matrix to data of a given N×N video block. The converting block has matrix elements leading data of the video block to resultant data that could be obtained by a converting process that applies DCT to the data, pads some zeros to coefficients, and applies IDCT to the coefficients including the padded zeros. The down-sampling method according to the present invention obtains an N×N reduced block by computing a converting block to a given 2N×2N video block. The converting block for reducing has matrix elements leading data of the 2N×2N video block to resultant data that could be obtained by a converting process that applies DCT to the data, removes some coefficients from transformed coefficients, and applies IDCT to the remaining coefficients.

    摘要: A method of transmitting data from a user terminal to a base station using a hybrid automatic repeat request (HARQ) scheme with a plurality of redundancy versions of said data, each of the redundancy versions (RV) indicating a transmission start position of a data block in a circular buffer is disclosed. For each retransmission, the redundancy version to be used by considering the previously used redundancy version and a predetermined sequence is determined. Within one sequence, at least two redundancy versions following each other have non consecutive start positions.
