MULTI-SUBCARRIER SYSTEM WITH MULTIPLE NUMEROLOGIES

Abstract:

A method of operating a user equipment comprises addressing multi-subcarrier system resources using multiple different numerologies available within a single carrier, the multiple different numerologies comprising a first numerology having resource blocks (RBs) with a first bandwidth and a first subcarrier spacing, .DELTA.f1, and a second numerology having RBs with a second bandwidth and a second subcarrier spacing, .DELTA.f2, which is different from .DELTA.f1, wherein the first numerology is aligned in the frequency domain relative to a frequency reference, Fref, according to m*.DELTA.f1+Fref and the second numerology is aligned in the frequency domain relative to the frequency reference, Fref, according to n*.DELTA.f2+Fref, where m and n are integers. The method further comprises transmitting and/or receiving information within the single carrier according to the at least one of the multiple different numerologies.
