FIELD: communication facilities. ^ SUBSTANCE: invention relates to communication engineering and can be used for providing of signalling at pilot information transmission by upperlink in wireless communication systems. For this at multiplexing of subranges, M used subranges in system is divided for Q non-intersecting group of subranges. Each group of subranges can be assigned to separate terminal for pilot information transmission by upperlink. Multitude of terminals can implement transmission simultaneously at assigned to it subranges. Power of pilot - signal transmission can be scaled with increasing for receiving of the same energy of pilot - signal, even if it is used S, instead of M subranges for pilot -signal transmission in each terminal. Pilot - signals transmission from terminals is received, and for each terminal it is introduced channel evaluation, on the basis of pilot - signal, accepted in assigned subranges. Channel evaluation contains response for additional subranges, not introduced into assigned group. ^ EFFECT: effectiveness increase of pilot -signal transmission and signalling by upperlink in system OFDM. ^ 30 cl, 10 dwg |
