TRANSFER OF CONTROL SIGNAL ALONG RETURN COMMUNICATION LINE BY REQUEST Russian patent published in 2011 - IPC H04L25/02 

FIELD: information technologies.

SUBSTANCE: control signals are sent by request along a return communication line and are used to assess a channel and data transfer along a forward communication line. The basic station selects at least one terminal to send a control signal by request along the return communication line. Each selected terminal is a candidate to receive data transfer along the forward communication line. The basic station assigns to each selected terminal with the help of time-frequency distribution, which may be for a wideband control signal, a narrowband control signal or some other type of a control signal. The basic station receives and processes transfer of a control signal by request from each selected terminal and extracts assessment of the channel for the terminal on the basis of the received transfer of a control signal. The basic station may plan terminals to transfer data along the forward communication line on the basis of channel assessments for all selected terminals. The basic station may also process data (for instance, carry out generation of a beam or internal control) for transfer into each planned terminal on the basis of its channel assessment.

EFFECT: improved efficiency of using system resources by means of more efficient transfer of control signals.
