Abstract:
1. A method of controlling transmission resources in a macro transmitting node for a hierarchical radio communication network, in which transmission resources are organized in a temporal succession on a carrier, the method comprising: the macro transmitting node transmitting normal transmission resources and reduced transmission resources according to a pattern such that the reduced transmission resources occur at varying predictable times in the temporal succession; wherein the pattern is a first pattern of the normal and reduced transmission resources during a first time period; the first pattern having a first length; wherein the pattern is a second pattern of the normal and reduced transmission resources in a second time period immediately subsequent to the first time period, the second pattern being a cyclic shift in time of the first pattern by an amount other than an integer multiple of the first length; wherein the first time period and the second time period have respective lengths that are at least twice the first length such that the first and second patterns are repeated during the first and second time periods, respectively; wherein transmission activity of reduced transmission resources is reduced with respect to transmission activity of normal transmission resources.
