Claim:
1. A method of determining a synchronous cell, comprising: determining, by a network-side apparatus, an extension carrier to be configured for a user equipment; and determining, by the network-side apparatus, a synchronous cell to which the extension carrier to be synchronous upon determining that the extension carrier is a synchronous extension carrier; wherein before the network-side apparatus determines the synchronous cell to which the extension carrier to be synchronous, the method further comprises: determining, by the network-side apparatus, that the user equipment supports a synchronous extension carrier; wherein determining, by the network-side apparatus, that the user equipment supports a synchronous extension carrier comprises: determining, by the network-side apparatus, from capability information reported by the user equipment whether the user equipment supports an extension carrier and whether type of the extension carrier is a synchronous extension carrier or an asynchronous extension carrier.
