  • Interference mitigation in a wireless communication system
    Patent number: 7855948
    Abstract: By virtue of one embodiment of the present invention, dynamic signal to noise ratio measurements made on received signals are used to identify degraded segments of a channel. The degraded segments are then no longer used for transmitting payload data. In the context of an orthogonal frequency division multiplexing (OFDM) communication system, degraded OFDM subchannels, as determined on a real-time basis, are not used to transmit payload data. In an OFDM network where access is shared in the time domain among multiple transmitters and a single allocable time slot includes an integer number of OFDM bursts, the medium access control layer adjusts packet length, and therefore the amount of data to be included in a given slot, in response to the fluctuating number of available subchannels.
    Type: Grant
