Methods and systems for adapting cellular downlink channels operating in the presence of non-stationary interference

A cellular base station, the cellular base station comprising:

• a communication interface configured to receive, from a user equipment (UE) radio, channel state information (CSI) for a cellular downlink channel between the cellular base station and the UE;
• an outer loop link adaptation module configured to determine, using one or more processors, a signal to interference and noise ratio (SINR) offset for the cellular downlink channel based upon (i) the CSI and (ii) a target block error rate (BLER);
• and
• a target BLER determination module configured to, using the one or more processors:
• detect a variance of the SINR offset for the cellular downlink channel that represents a presence of non-stationary interference, wherein the non-stationary interference is caused by one or more bursty, frequency-hopping transmissions from a plurality of devices operating within a vicinity of the UE and the one or more bursty, frequency-hopping transmissions occur in a frequency band used for the cellular downlink channel, and
• modify the target BLER based upon the variance of the SINR offset for the cellular downlink channel such that the cellular downlink channel adapts to the presence of the non-stationary interference.

A non-transitory, computer-readable storage medium storing instructions that, when executed by one or more processors, cause a cellular base station to:

• receive, from a user equipment (UE) radio, channel state information (CSI) for a cellular downlink channel between the cellular base station and the UE;
• determine a signal to interference and noise ratio (SINR) offset for the cellular downlink channel based upon (i) the CSI and (ii) a target block error rate (BLER);
• detect a variance of the SINR offset for the cellular downlink channel that represents a presence of non-stationary interference, wherein the non-stationary interference is caused by one or more bursty, frequency-hopping transmissions from a plurality of devices operating within a vicinity of the UE and the one or more bursty, frequency-hopping transmissions occur in a frequency band used for the cellular downlink channel;
• and
• modify the target BLER based upon the variance of the SINR offset for the cellular downlink channel such that the cellular downlink channel adapts to the presence of the non-stationary interference.
