FIELD: radio engineering, communication.SUBSTANCE: group of inventions relates to means for flexible spectrum allocation in communication systems. Disclosed is a method for flexible allocation of a shared frequency spectrum to a plurality of users which comprises steps of assigning one or more clusters from a set of clusters of subcarriers identified by an identifier and associated with a sector to a user, wherein the set of clusters of subcarriers is allocated for channel sensitive scheduling (CSS), and wherein users of a first group are fixedly assigned clusters in a first group and channel quality does not change significantly over time; and assigning one or more other clusters from another set of clusters of subcarriers associated with a sector to another user, wherein the other set of clusters of subcarriers is allocated for frequency hopping (FH) scheduling and wherein users of a second group are assigned clusters in the second group and users of the second group can hop frequency within the assigned group of clusters.EFFECT: improved frequency diversity of interference in communication systems.36 cl, 3 dwg |
