The embodiments of the present invention relate to a data transmission method and apparatus and a switching device. The method comprises: a CPRI switching device receives an uplink MAC frame sent by a wireless backhaul device, wherein the wireless backhaul device obtains the uplink MAC frame by converting an uplink wireless MAC frame sent by a second BTS after receiving same; and the CPRI switching device bears the uplink MAC frame on a CPRI and sends the borne uplink MAC frame to a first BTS for the first BTS to forward the uplink MAC frame to a transmission network. The data transmission method and apparatus, and the switching device provided in the embodiments of the present invention reduce the difficulty of wiring in an indoor coverage scenario. |
