[0002] Under the unlicensed spectrum in the 5G NR (New Radio, new air interface) system, the base station can support simultaneous transmission of multiple bandwidth parts (Bandwidth Part, bandwidth part), but for the terminal, it can only determine the bandwidth of the multiple bandwidth parts. A portion of the bandwidth that is activated for data transmission with the base station
[0003] If the terminal is activated on a bandwidth part whose frequency value is in the middle among multiple bandwidth parts, but this bandwidth part is occupied by other terminals at this time, for example figure 1 As shown, the terminal would like to transmit data through other bandwidth parts, and in related technologies, the terminal side cannot know other available bandwidth parts

The present disclosure provides a method and device for configuring a bandwidth part, wherein the method includes: determining first target indication information; the first target indication information is used to indicate whether each bandwidth part in the plurality of bandwidth parts is available ; Simultaneously sending the multiple bandwidth parts and the first target indication information to a terminal that supports simultaneous reception of the multiple bandwidth parts. In the present disclosure, the terminal can determine whether each bandwidth part is available based on the target indication information, which lowers the requirements for radio frequency indicators on the base station side, and can determine whether each bandwidth part in multiple bandwidth parts is available on the terminal side, satisfying multiple High-efficiency communication requirements in the bandwidth part.
Description
technical field [0001] The present disclosure relates to the field of communications, and in particular to a method and device for configuring bandwidth parts. Background technique [0002] Under the unlicensed spectrum in the 5G NR (New Radio, new air interface) system, the base station can support simultaneous transmission of multiple bandwidth parts (Bandwidth Part, bandwidth part), but for the terminal, it can only determine the bandwidth of the multiple bandwidth parts. A bandwidth part that is activated, so that data transmission with the base station is performed through the bandwidth part. [0003] If the terminal is activated on a bandwidth part whose frequency value is in the middle among multiple bandwidth parts, but this bandwidth part is occupied by other terminals at this time, for example figure 1 As shown, the terminal may wish to transmit data through other bandwidth parts, and in related technologies, the terminal side cannot know other available bandwidth...
