<p>Embodiments of the present invention provide a method, a device, and a system for selecting a relay type. The method includes: selecting, by a relay node, a Un interface frequency band with an optimal signal according to frequency bands supported on a Un interface; and determining, by the relay node, a relay type according to the selected Un interface frequency band and a configured Uu interface frequency band, and sending indication information to a DeNB, where the indication information includes the selected Un interface frequency band and the relay type. In the method, the device, and the system for selecting a relay type according to the embodiments of the present invention, an RN selects a frequency band with an optimal signal according to frequency bands supported on a Un interface and then determines a relay type; and a DeNB may switch the relay type determined by the RN, so that the relay type is adaptively selected according to quality and an interference condition of each of the frequency bands supported on the Un interface, thereby reducing an operating cost for configuring the RN and improving configuration efficiency.</p> |
