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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for transmitting band bitmap in wireless communication system","description":"A method for transmitting a band bitmap in a wireless communication system is provided.
