Abstract
Operating a UE device having a single radio configured to communicate using a first and second RAT. The UE may begin operating in a connected discontinuous reception (CDRX) mode of the first RAT, where the CDRX mode comprises an on duration timer and an inactivity timer. The method may determine that the single radio of the UE is being used for a second RAT during the CDRX mode. The UE may operate at least one of a CDRX on duration timer or an inactivity timer of the first RAT while the single radio of the UE is being used for the second RAT. While the single radio of the UE is being used for the second RAT, the at least one of the CDRX on duration timer or the inactivity timer may operate even though no communication or monitoring is performed on the first RAT.
Claims20
An apparatus, comprising:
- a processor, wherein the processor is configured to operate with a first radio of a user equipment (UE), wherein the first radio is configured to perform communication using a first radio access technology (RAT) and a second RAT, wherein the processor and the first radio are configured to:
- operate in a connected discontinuous reception (CDRX) mode of the first RAT, wherein the CDRX mode comprises an on duration timer and an inactivity timer;
- determine that the first radio of the UE is being used for the second RAT instead of the first RAT during the CDRX mode;
- operate at least one of a CDRX on duration timer or an inactivity timer of the first RAT while the first radio of the UE is being used for the second RAT, wherein, while the first radio of the UE is being used for the second RAT, the at least one of the CDRX on duration timer or the inactivity timer operates even though no communication or monitoring is performed by the first radio on the first RAT.
An apparatus, comprising:
- a processor, wherein the processor is configured to operate with a first radio of a user equipment (UE), wherein the first radio is configured to perform communication using a first radio access technology (RAT) and a second RAT, wherein the processor and the first radio are configured to:
- begin operating according to the first RAT during an on period of a connected discontinuous reception (CDRX) mode of the first RAT;
- determine that the first radio is being used for tune-away operations of a second RAT;
- start a CDRX on duration timer of the first RAT, wherein the CDRX on duration timer is started even though no monitoring is performed on the first RAT;
- start a CDRX inactivity timer in response to expiration of the CDRX on duration timer, wherein each of the CDRX on duration timer and the inactivity timer of the first RAT operate while the first radio is used for the tune-away operations of the second RAT.
A user equipment device (UE), comprising:
- a first radio, wherein the first radio is configured to perform communication using a first radio access technology (RAT) and a second RAT and maintain a connection to both the first RAT and the second RAT;
- and
- one or more processors coupled to the first radio, wherein the one or more processors and the first radio are configured to:
- begin operating according to the first RAT during an on period of a connected discontinuous reception (CDRX) mode of the first RAT;
- determine that the first radio is being used for tune-away operations of a second RAT;
- start a CDRX on duration timer of the first RAT, wherein the CDRX on duration timer is started even though no monitoring is performed on the first RAT.
