Abstract: A resource allocation method includes: determining a resource block allocation field in downlink control information, where in response to a value indicated by five least significant bits of the resource block allocation field is greater than 20, the resource block allocation field indicates a quantity of resource block groups allocated to a terminal device and an index of a starting resource block group allocated to the terminal device. The method can be applied to the Internet of Things, such as MTC, IoT, LTE-M, M2M, etc.

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.

Abstract: A resource allocation method includes: determining a resource block allocation field in downlink control information, where when a value indicated by five least significant bits of the resource block allocation field is less than or equal to 20, the five least significant bits of the resource block allocation field indicate a resource that is allocated within an indicated narrowband by using an uplink resource allocation type 0; or when a value indicated by five least significant bits of the resource block allocation field is greater than 20, the resource block allocation field indicates a quantity of resource block groups allocated to a terminal device and an index of a starting resource block group allocated to the terminal device. The method provided in this embodiment improves the coverage capability of the network. The method can be applied to the Internet of Things, such as MTC, IoT, LTE-M, M2M, etc.

Abstract: Embodiments of the disclosure provide a carrier selection method and device for multicarrier, to implement that an optimal carrier combination is obtained by searching. The method includes: acquiring an absolute radio frequency channel number ARFCN that is of each carrier of N carriers allocated to a receiving end and in each frame of a radio block, where N is a positive integer, and N≧2; respectively selecting, from the N carriers, a different carrier as an anchor carrier, and searching within a search range of the anchor carrier according to the ARFCN of each carrier in each frame of the radio block and a maximum carrier frequency spacing supported by the receiving end, to determine a carrier set of the anchor carrier; and selecting, from the carrier sets of anchor carriers of the N carriers, at least one carrier set as a carrier selection result.
