INSERTING VIRTUAL CARRIER IN CONVENTIONAL OFDM HOST CARRIER IN COMMUNICATIONS SYSTEM |
摘要 |
A base station communicating data to/from plural mobile terminals over plural OFDM sub-carriers within a coverage area. The base station allocates transmission resources provided by a first group of the plural OFDM sub-carriers within a first frequency band to mobile terminals of a first type and allocates transmission resources provided by a second group of the plural 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 selected from within the first frequency band. The base station transmits control information including 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 transmits control information including resource allocation information for terminals of the second type over a second bandwidth corresponding to the second group of OFDM sub-carriers. |
