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

摘要

FIELD: information technology.;SUBSTANCE: method and for wireless communication between a mobile communication terminal and a base station includes a step for exchanging a physical resource unit (PRU) between the base station and the mobile communication terminal, the PRU having a plurality of OFDMA symbols. Each l^th symbol includes: n₁ pilots allocated per a predetermined pilot allocation scheme, the remaining L_DRU (P_sc-n₁) data subcarriers renumbered in order, from 0 to L_DRU (P_sc-n₁)-1, with logically contiguous renumbered subcarriers grouped into L_DRU. L_pair,1 tone pairs and renumbered 0 to L_DRU. L_pair,1-1, and logically contiguous formed tone pairs (i. L_pair,1; (i+1). L_pair,1-1) having a predetermined permutation formula applied to map into ith distributed LRUs, where i = 0, 1,…, L_DRU-1.;EFFECT: high efficiency of using the frequency band.;12 cl, 16 dwg
