摘要
FIELD: telecommunications.;SUBSTANCE: invention relates to telecommunications and can be used in systems with multiple subcarriers using several numerology. Method of operating a wireless communication device or a radio access node comprises addressing system resources with multiple subcarriers using at least one of several different numerologies available within one carrier, wherein several different numerologies contain first numerology, having resource blocks with first bandwidth and first separation between subcarriers Δf1, and second numerology having RB with second pass band and second separation between subcarriers Δf2, which differs from Δf1, wherein the first numerology is aligned in the frequency domain relative to the reference frequency Fref according to the expression m*Δf1+Fref, and second numerology is aligned in frequency domain relative to reference frequency Fref according to expression n*Δf2+Fref, where m and n are integers. Method further comprises transmitting and / or receiving information within one carrier according to at least one of several different numerology.;EFFECT: reduced inter-cell interference.;26 cl, 18 dwg
