INCREASING PILOT CARRIER ACTIVATION FOR CHANNEL AND INTERFERENCE ASSESSMENT Russian patent published in 2009 - IPC H04L27/26 

FIELD: communication facilities.

SUBSTANCE: invention concerns systems, devices and methods of dynamic resource assignment for selective boost of channel assessment property of a receiver in multiple access system with orthogonal frequency distribution (OFDMA). Wireless communication system can use configuration of common pilot channel in channel assessment at one or more receivers establishing communication with the system. Receiver establishing communication with the system can be unable to demodulate received data due to incorrect channel assessment. Receiver can send request for additional channel assessment resources to a system transmitter. Wireless communication system can provide additional resources of channel assessment by inclusion of dedicated pilot channels to one or more frequencies selected for the receiver symbols. If the receiver still cannot demodulate received data, wireless communication system can include additional increasing pilot channels to the receiver symbol.

EFFECT: enhanced reception accuracy.
