A COMMUNICATION SYSTEM AND METHOD OF ALLOCATING RESOURCE THEREFORE

摘要

This invention relates to system for allocating resource in a cellular communication system (200) having cell specific spreading codes. A interference processor (239) identifies taht a detrimental interference relationship exists between a first group of subscriber units (211, 215, 219). A code allocator (241) allocates a common spreading code to the first group of subscriber units (211, 215, 219) thereby creating a shared resource. A resource allocator (243) then allocates resource of the sahred resource between the subscriber units of the first group (211, 215, 219) and resource of the cell specific spreading code to the remaining subscriber units. joint detection is used for the subscriber units (211, 215, 219) of the first group of subscriber units whereby inter-cell interference is significantly reduced. The invention is applicable to a plurality of communication systems using cell separation spreading codes and in particular to UMTS TDD communication systems.
