Abstract

A user equipment (UE) may monitor a channel for wireless communication associated with a first radio access technology (RAT) during one or more of a first active duration or a first inactive duration. The UE may operate in a first power mode during the first inactive duration. The UE may monitor the channel for wireless communication associated with a second RAT during one or more of a second active duration or a second inactive duration. The UE may operate during the second inactive duration in one or more of the first power mode or a second power. The UE may operate according to the first mode or the second mode based on the monitoring of the channel associated with the first RAT and the second RAT.

First claim

What is claimed is:

1. A method for wireless communication at a device, comprising:
receiving first wireless communications associated with a first radio access technology during one or more of a first active duration associated with a first power mode or a first inactive duration associated with a second power mode that consumes less power than the first power mode; and
receiving second wireless communications associated with a second radio access technology during one or more of a second active duration associated with the first power mode or a second inactive duration associated with the second power mode, the device operating in a third power mode different from the second power mode during at least a portion of the second inactive duration when the first active duration associated with the first radio access technology overlaps with the second active duration associated with the second radio access technology, wherein the device switches from the first power mode to the third power mode without reconfiguring one or more radio frequency front-end switches shared between the first radio access technology and the second radio access technology.

2. The method of claim 1 , wherein the device includes a radio transceiver chain for one or more of receiving or transmitting wireless communications associated with one or more of the first radio access technology or the second radio access technology.

3. The method of claim 2 , further comprising:
operating the radio transceiver chain associated with the device in the first power mode during the first inactive duration based at least in part on monitoring for the first wireless communications associated with the first radio access technology during one or more of the first active duration or the first inactive duration.

4. The method of claim 3 , wherein receiving the first wireless communications associated with the first radio access technology comprises:
enabling the radio transceiver chain to monitor for the first wireless communications associated with the first radio access technology during the first active duration based at least in part on a timer;
activating the timer based at least in part on enabling the radio transceiver chain to monitor for the second wireless communications associated with the first radio access technology during the first active duration; and
disabling the radio transceiver chain from monitoring for the first wireless communications associated with the first radio access technology by switching the radio transceiver chain to operate in the first power mode during the first inactive duration based at least in part on the timer expiring.

5. The method of claim 3 , further comprising:
operating the radio transceiver chain associated with the device in one or more of the first power mode or the second power mode during the second inactive duration based at least in part on monitoring of for the second wireless communications associated with the second radio access technology during one or more of the second active duration or the second inactive duration.

6. The method of claim 5 , wherein receiving the second wireless communications associated with the second radio access technology comprises:
enabling the radio transceiver chain to monitor for the second wireless communications associated with the second radio access technology during the second active duration based at least in part on a timer;
activating the timer based at least in part on enabling the radio transceiver chain to monitor for the second wireless communications associated with the second radio access technology during the second active duration; and
disabling the radio transceiver chain from monitoring for the second wireless communications associated with the second radio access technology by switching the radio transceiver chain to operate in the first power mode or the second power mode during the second inactive duration based at least in part on the timer expiring.

7. The method of claim 6 , further comprising:
switching the radio transceiver chain to operate in the first power mode during the second inactive duration based at least in part on an absence of an overlap between the first inactive duration and one or more of an ending portion of the second active duration or a beginning portion of a third active duration following the second active duration.

8. The method of claim 6 , further comprising:
switching the radio transceiver chain to operate in the second power mode during the second inactive duration based at least in part on the first inactive duration overlapping with one or more of an ending portion of the second active duration or a beginning portion of a third active duration following the second active duration.

9. The method of claim 2 , further comprising:
receiving control signaling indicating a configuration for the device, the configuration indicating one or more of the first active duration, the first inactive duration, the second active duration, the second inactive duration, or a third active duration following the second active duration,
wherein operating the radio transceiver chain in one or more of the first power mode or the second power mode is based at least in part on the configuration.

10. The method of claim 1 , further comprising:
adjusting the second active duration based at least in part on a portion of the first active duration overlapping with a portion of the second active duration.

11. The method of claim 10 , further comprising:
determining one or more of a beginning of the first active duration or a beginning of the second active duration based at least in part on scheduling information; and
adjusting the beginning of the second active duration to occur before the beginning of the first active duration based at least in part on determining that the portion of the first active duration overlaps with the portion of the second active duration.

12. The method of claim 10 , further comprising:
determining one or more of an ending of the first active duration or an ending of the second active duration based at least in part on scheduling information; and
adjusting the ending of the second active duration to occur after the ending of the first active duration based at least in part on determining that the portion of the first active duration overlaps with the portion of the second active duration.

13. The method of claim 1 , further comprising:
allocating, based at least in part on a configuration, a first set of antennas associated with the device to monitor for the first wireless communications associated with the first radio access technology during one or more of the first active duration or the first inactive duration; and
allocating, based at least in part on the configuration, a second set of antennas associated with the device to monitor for the second wireless communications associated with the second radio access technology during one or more of the second active duration or the second inactive duration.

14. The method of claim 13 , wherein the first set of antennas are nonoverlapping with the second set of antennas.

15. The method of claim 13 , further comprising:
reallocating one or more of the first set of antennas or the second set of antennas based at least in part on one or more of the first active duration or the second active duration.

16. The method of claim 1 , further comprising:
managing one or more memory registers associated with the device for one or more of the first radio access technology and the second radio access technology, the one or more memory registers co
