ALTERNATION OF OFDMA CONTROL CHANNELS Russian patent published in 2010 - IPC H04W74/08 

FIELD: information technologies.

SUBSTANCE: invention relates to device and method for alternation of transfers in control channels with arbitrary access of multiple access wireless communication system with orthogonal frequency separation of signals (OFDMA). Device of wireless communication may alternate transfers between multiple servicing sectors. Device of wireless communication may alternate transfers using number of alternations equal to number of separate control channels, along which transfer is planned. In other version of invention, device of wireless communication breaks multiple planned transfers of control channels into two or more sets, and may alternate these sets. In another version of invention device of wireless communication may reserve the first alternation for transfer of control channels for communication with servicing sector and may implement time multiplexing of other transfers in control channels by the second alternation.

EFFECT: wireless communication device that executes transfer along separate control channels of OFDMA to multiple servicing sectors may operate under conditions of communication line limitation.
