Abstract
There is provided a communication system, comprising a network infrastructure comprising: a transmitter configured to transmit signaling information to user terminals, the signaling information being related to the allocation of the plurality of sub-carriers at a common frequency band used for data transmission between the multiple user terminals and a network infrastructure; a processor configured to divide the common frequency band into two suppression bands at the edge zones of the common frequency band and to provide a safe band between the two suppression bands, the two suppression bands including sub-carriers having a predetermined amount of decreased channel estimation accuracy compared with the other sub-carriers of the common frequency band; and a processor configured to allocate signaling information, related to the allocation of at least one sub-carrier to a user terminal having an expected signal to interference-plus-noise ratio at a predetermined level, to at least one sub-carrier included in the safe band.
