    Abstract: Disclosed herein is a mobile device including a communication section that performs communication with a controller which selectively transmits control signals to a plurality of mobile devices, and a data processing section that performs movement control of the own device. The data processing section confirms whether or not an own-device selection signal which indicates that the own device is selected as a control target device has been received from the controller and, upon confirming reception of the own-device selection signal, performs movement control to cause the own device to move in accordance with a selected-device identification track which indicates that the own device is selected as the control target device.

    Abstract: A method and device for feeding back downlink channel feedback information, and a method and device for user pairing. The method for feeding back downlink channel feedback information includes: calculating the multi-user channel quality indication error of a user, which error is used to reflect the difference in channel quality indication between the situation of multi-user multiple input multiple output transmission and the situation of single user multiple input multiple output transmission; adding the multi-user channel quality indication error into the downlink channel feedback information which includes a pre-coding matrix indication and a channel quality indication, and feeding the same back to a base station for scheduling. Therefore, the bit error rate of demodulation in the MIMO system can be reduced and the system performance can be improved.
