Abstract:
1. An apparatus for granting data rates to users in a radio network, comprising: a scheduler arranged to grant data rates to users present within a first cell of said radio network; an origin determination unit arranged to determine whether a new user in the first cell originates from an cell that is adjacent to the first cell, and an interference determination unit arranged to (a) provide a measure of a total interference level within the cell, said total interference level being a sum of a first interference part related to interference from users within the cell and a second interference part related to interference from users outside the cell and (b) determine a first relation between a set maximum interference value and the measured total interference level, wherein the apparatus is configured such that, if the origin determination unit has determined that the new user originates from a cell adjacent to the first cell, then: (i) the interference determination unit adjusts the determined first relation to produce a second relation, and (ii) the scheduler grants data rate to the new user based on the second relation.
