Disclosed are methods, systems, apparatus, and computer programs for configuring a UE to operate within an unlicensed spectrum. In one aspect, a method includes receiving from a radio access network (RAN) a first uplink scheduling grant; determining, based on the first uplink scheduling grant, that an uplink communications grant has not been received for a first uplink subframe of an uplink burst, wherein the uplink burst comprises an ordered plurality of uplink subframes; determining that the first uplink scheduling grant schedules communication in a second uplink subframe of the uplink burst; and performing, in response to the determination, a mitigating action to avoid a communication error with the RAN. |
