Abstract
Official abstract text for this publication.
The capacity of a cellular wireless system is increased by operation of base stations or base station sectors arranged to re-use radio resource elements that are used by neighboring base stations or base station sectors, in conjunction with operation of relay stations, which are similarly arranged to re-use radio resource elements used by neighboring relay stations, and where the radio resource elements re-used by the relay stations are different to those used by the base stations. The relay stations provide coverage, particularly in the areas at the boundaries between the areas of coverage of base stations that suffer from interference between signals transmitted from the respective base stations. In addition, the relay stations generally increase the average available carrier to interference ratio compared with a system in which base stations alone are deployed. The scheme for the allocation of radio resource elements ensures in particular that interference is avoided between signals transmitted from a base station and signals transmitted from a relay station in radio resource elements allocated to control data.
First claim
Opening claim text (preview).
The invention claimed is: 1. A cellular wireless network using orthogonal frequency division multiplexing (OFDM) comprising a plurality of base stations and a plurality of relay stations, the network being arranged to allocate radio resources within the network in accordance with a frame structure comprising first selected frequencies corresponding to a first sub-set of OFDM subcarriers and second selected frequencies corresponding to a second, different sub-set of OFDM subcarriers…
