INSERTING VIRTUAL CARRIER IN CONVENTIONAL OFDM HOST CARRIER IN COMMUNICATIONS SYSTEM
摘要
A method of allocating transmission resources in an OFDM wireless telecommunication system arranged to communicate data using a plurality of OFDM sub- carriers. The method comprises allocating transmission resources provided by a first group of the plurality of OFDM sub-carriers within a first frequency band to terminals of a first type; allocating transmission resources provided by a second group of the plurality of OFDM sub- carriers within a second frequency band to terminals of a second type, the second group being smaller than the first group and the second frequency band being selected from within the first frequency band; transmitting control information comprising resource allocation information for terminals of the first type over a first bandwidth corresponding to the combined first and second groups of OFDM sub-carriers; and then transmitting control information comprising resource allocation information for terminals of the second type over a second bandwidth corresponding to the second group of OFDM sub-carriers.
