Cooperative communication methods for a wireless communication network (100) and devices configured to perform such methods are disclosed herein. In a described embodiment, the network (100) includes a first communication device (102) and a second communication device (104), each of the communication devices (102,104) being associated with respective users and configured to communicate with a common base station (130). The cooperative communication method comprises the first communication device (102) transmitting a first message to the second communication device (104) for transmission to the base station (130) as a first routed message; and receiving a second message from the second communication device (104) for transmission to the base station (130) as a second routed message. In this way, the transmission is able to achieve diversity gains at the base station (130).
