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 lth symbol includes: n1 pilots allocated per a predetermined pilot allocation scheme, the remaining LDRU (Psc-n1) data subcarriers renumbered in order, from 0 to LDRU (Psc-n1)-1, with logically contiguous renumbered subcarriers grouped into LDRU. Lpair,1 tone pairs and renumbered 0 to LDRU. Lpair,1-1, and logically contiguous formed tone pairs (i. Lpair,1; (i+1). Lpair,1-1) having a predetermined permutation formula applied to map into ith distributed LRUs, where i = 0, 1,Ç, LDRU-1. ^ EFFECT: high efficiency of using the frequency band. ^ 12 cl, 16 dwg |
