Cyclic Redundancy Check False Alarm Mitigation

A method, comprising:

• determining, by a system comprising at least one processor, that a cyclic redundancy check passes for data received on a channel established via a broadband cellular communications network;
• based on the determining that the cyclic redundancy check passes for the data, decoding, by the system, a payload of the data to produce a transmitted signal;
• determining, by the system, a metric of signal quality for the channel based on reference symbols of the transmitted signal, and at least some data symbols reconstructed from a data payload of the transmitted signal that passes for the cyclic redundancy check;
• evaluating, by the system, the metric of signal quality with respect to a signal quality criterion, to produce a signal quality evaluation result;
• and
• where the signal quality evaluation result indicates that the metric of signal quality is less than the signal quality criterion, classifying, by the system, the data as a discontinuous transmission.

A non-transitory computer-readable medium comprising instructions that, in response to execution, cause a system comprising at least one processor to perform operations, comprising:

• based on an error-detection code passing for data received on a channel of broadband cellular communications, decoding a payload of the data to produce a transmitted signal;
• determining a metric of signal quality for the channel based on at least a portion of a data payload of the transmitted signal;
• comparing the metric of signal quality to a threshold value determined with reference to a signal quality criterion, to produce a signal quality result;
• and
• in response to the signal quality result indicating that the metric of signal quality is greater than or equal to the threshold value, determining that the data is valid.
