Claim 6:
7. A method for accessing a sub-band, comprising:
detecting a synchronization signal and a broadcast channel in a basic sub-band to obtain a master information block carried by the broadcast channel, and camping on a cell according to the synchronization signal;
decoding the master information block carried by the broadcast channel to determine sub-band configuration of at least one non-basic sub-band, wherein the sub-band configuration comprises a sub-carrier spacing and a frequency position; and
accessing the at least one non-basic sub-band based on the sub-band configuration of the at least one non-basic sub-band, when data interaction through the at least one non-basic sub-band is required,
wherein decoding the master information block carried by the broadcast channel to determine sub-band configuration of at least one non-basic sub-band comprises: decoding the master information block carried by the broadcast channel to obtain configuration of a common control channel, wherein the configuration of the common control channel comprises a time-frequency resource position of the common control channel; decoding the common control channel based on the configuration of the common control channel to determine a system information block carried by the common control channel; and decoding the system information block carried by the common control channel to determine the sub-band configuration of the at least one non-basic sub-band.
