Claim 10:
11. A device for accessing a sub-band, comprising:
a detecting circuitry configured to detect a synchronization signal and a broadcast channel in a basic sub-band to obtain a master information block carried by the broadcast channel, and camp on a cell according to the synchronization signal;
a decoding circuitry configured to decode 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, a Cyclic Prefix (CP) length and a frequency position; and
an accessing circuitry configured to access 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 the decoding circuitry comprises:
a broadcast channel decoding sub-circuitry configured to decode 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;
a common control channel decoding sub-circuitry configured to decode 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
a sub-band configuration determining sub-circuitry configured to decode 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.
