Abstract
An apparatus and method for interference mitigation comprising determining if an unscheduled service transmission frequency is in a predefined frequency range; determining if an unscheduled service transmission power is less than a predefined power threshold; and performing one or both of the following: a) erase the baseband signal when an unscheduled service transmission is ON and stop the channel estimation process when the unscheduled service transmission is ON; b) initiate a smart channel information report.
Claims59
A method for interference mitigation comprising:
- determining whether a frequency of an unscheduled service transmission signal is within a predefined frequency range;
- determining whether a power level of the unscheduled service transmission signal satisfies a predefined power threshold;
- and
- in response to a determination that the frequency is within the predefined frequency range and a determination that the power level does not satisfy the predefined power threshold, performing one or both of the following:
- erasing a baseband signal associated with a scheduled service reception signal during a time period when an unscheduled service transmission is on, wherein the unscheduled service transmission signal interferes with the baseband signal;
- and
- initiating a smart channel information report, wherein initiating the smart channel information report includes reporting information to an access node that helps the access node avoid packet transmission in a timeslot that corresponds to a potential collision between a portion of the unscheduled service transmission signal and a portion of the scheduled service reception signal.
