Detecting multiple input multiple output (MIMO) communications comprising: transmitting from a network device, such as a base station (12), to a communications device, such as a mobile terminal (10), a first control signal indicating a number of data streams (carried on control channels) which the communications device may utilise to transmit data; detecting discontinuous transmission on control channels indicated by the control channels, and thereby determining on which control channels the communications device is currently communicating. |
