Abstract
A method, a device, and a system for duplex communications. Uplink and downlink frequencies are allocated in an orthogonal manner such that at one time instant a certain carrier frequency is used for uplink (downlink) transmission and at some other time instant for downlink (uplink) transmission. Correspondingly, at said one time instant a second carrier frequency is used for downlink (uplink) transmission and at said some other time instant optionally for uplink (downlink) transmission.
