METHOD AND APPARATUS FOR INDICATING UPLINK-DOWNLINK CARRIER FREQUENCY SPACING, AND METHOD AND APPARATUS FOR OBTAINING UPLINK-DOWNLINK CARRIER FREQUENCY SPACING
First Claim
1. A method for obtaining an uplink-downlink carrier frequency spacing, wherein the method is applied to an Narrowband Internet of Things (NB-IoT) system, and comprises:
- initiating, by a terminal device (UE), a request in a first cell to access an NB-IoT, and receiving an indication message sent by a base station, wherein the indication message is used to indicate an uplink-downlink carrier frequency spacing corresponding to the first cell; and
determining, by the UE according to the indication information, the uplink-downlink carrier frequency spacing corresponding to the first cell.

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.
