Abstract:
This disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for obtaining an uplink-downlink carrier frequency spacing. The method for obtaining an uplink-downlink carrier frequency spacing may include initiating, by user equipment (UE), a request in a first cell to access an NB-IoT, and receiving an indication message sent by a base station. The method may also include determining, by the UE according to the indication information, an uplink-downlink carrier frequency spacing corresponding to the first cell. Therefore, the base station can notify the UE of the uplink-downlink carrier frequency spacing corresponding to the first cell, so that the terminal obtains a correct uplink carrier frequency.

Claim (Index 6):
The method according to  claim 1 , wherein the determining, by the UE according to the indication information, the uplink-downlink carrier frequency spacing corresponding to the first cell comprises:\n when the UE determines that the indication information carries an uplink-downlink basic carrier frequency spacing corresponding to a frequency band used by the first cell, an index number corresponding to a first carrier frequency deviation in a first carrier frequency deviation set, and a difference between index numbers of uplink and downlink physical resource blocks used by the first cell, determining, by the UE, the first carrier frequency deviation according to the index number corresponding to the first carrier frequency deviation in the first carrier frequency deviation set; and calculating, by the UE, a sum of the first carrier frequency deviation, the uplink-downlink basic carrier frequency spacing, and a product of physical resource block bandwidth and the difference between the index numbers of the uplink and downlink physical resource blocks, to obtain the uplink-downlink carrier frequency spacing of the first cell, wherein the first carrier frequency deviation set comprises all possible carrier frequency deviations and index numbers corresponding to all the carrier frequency deviations, or comprises all possible in-band carrier frequency deviations and index numbers corresponding to all the in-band carrier frequency deviations.
