A METHOD FOR DESIGNING MINI RESOURCE UNIT AND TRANSMISSION FOR A DISTRIBUTED RESOURCE UNIT IN CONSIDERATION OF SPACE FREQUENCY BLOCK CODE

摘要

between the mobile station and the base station in the wireless communications to a method and apparatus for the public. The method includes exchanging a physical resource unit (Physical Resource Unit, PRU) between the base station and the mobile communication terminal. The PRU includes a plurality of OFDMA symbols. L-th OFDMA symbol of each PRU is included in the n _l of pilots allocated in accordance with a predetermined pilot allocation scheme, L remaining in the l-th OFDMA symbol _DRU (P _sc -n _l ) of data subcarriers from 0 L _DRU (P _sc -n _l ) - 1 Li and Numbering (renumber) in order to logically consecutive renumbering sub-carriers L _DRU L _{pair, l} are grouped into pairs 0 to L _DRU L _{pair, l} and re-numbering to -1, logically contiguous formed tone-pairs (i L _{pair, l} ; (i + 1) L _{pair, l} -1) are subject to the permutation formula predetermined for each pair of the i-th distributed LRU (distributed LRU) maps to, wherein i = 0,1, ..., L _{and DRU} -1, L _DRU represents the number of the DRU, P _sc represents the number of sub-carriers in the PRU, L _{pair, l} = (P _sc - n _l ) it is / 2. ; distributed resource unit
