Conflict Handling in a Device Configured to Operate According to Multiple Cellular Communication Protocols

A wireless user equipment (UE) device, the UE comprising:

• a radio, comprising one or more antennas configured for wireless communication;
• a processing element operably coupled to the radio;
• wherein the radio and the processing element are configured to:
• operate the radio according to either of a first radio access technology (RAT) or a second RAT;
• determine that scheduled wakeup times in discontinuous reception (DRX) modes of operation for the first and second RAT conflict at a first time;
• operate the radio according to the first RAT during the first time;
• and
• determine a next wakeup time for the second RAT based at least in part on a most recent signal strength measurement of a serving cell according to the second RAT.

A non-transitory computer accessible memory medium, comprising program instructions that, when executed at a wireless user equipment (UE) device, cause the UE to:

• operate in a discontinuous reception (DRX) mode according to both a first RAT and a second RAT using a shared radio, wherein DRX according to the first RAT has a first DRX cycle and DRX according to the second RAT has a second DRX cycle;
• determine that a first wakeup time according to the first DRX cycle conflicts with a second wakeup time according to the second DRX cycle;
• operate the radio according to the first RAT during the first wakeup time, wherein the second RAT does not operate the radio during the second wakeup time based on determining that the first wakeup time conflicts with the second wakeup time;
• and
• select a next wakeup time for the second RAT based on determining that the first wakeup time conflicts with the second wakeup time,
• wherein a time substantially immediately after the first wakeup time is selected under one or more of a first set of conditions,
• wherein a next scheduled wakeup time according to the second DRX cycle is selected under one or more of a second set of conditions.
