Abstract
A method for transmitting a band bitmap in a wireless communication system is provided. The method includes selecting at least one selection band from a plurality of bands, the plurality of bands being distributed throughout a whole frequency band, grouping the plurality of bands into a plurality of band groups, setting a primary bitmap for each band group according to whether the selection band is included in each band group and setting a secondary bitmap for bands in each band group, and transmitting the primary bitmap and the secondary bitmap. Radio resources used to transmit a band bitmap can be reduced by decreasing the number of bits of the band bitmap.
Claims6
A method for transmitting a band bitmap in a wireless communication system, the method comprising:
- selecting at least one selection band from a plurality of bands, the plurality of bands being distributed throughout a whole frequency band;
- grouping the plurality of bands into a plurality of band groups;
- setting a primary bitmap for each of the plurality of band groups according to whether the at least one selection band is included in each of the plurality of band groups;
- setting a secondary bitmap only for at least one selection band group including the at least one selection band according to a position of the at least one selection band in the at least one selection band group;
- and
- transmitting the primary bitmap and the secondary bitmap.
