Signal for a synchronized communication system operating in a shared spectrum frequency band
First Claim
1. A method for wireless communication at a user equipment (UE), comprising:
- entering a first power mode of the UE in a synchronized communication system operating in a shared spectrum frequency band;
performing, in a second power mode, discontinuous monitoring of a plurality of potential locations for a signal, wherein the second power mode is higher than the first power mode;
receiving the signal in one of the plurality of potential locations;
entering a third power mode, based at least in part on receiving the signal, to process a control resource set associated with a downlink transmission opportunity, wherein the third power mode is higher than the first power mode and the second power mode;
determining that a content of the downlink transmission opportunity will include content for the UE based at least in part on processing the control resource set; and
monitoring at least a portion of the downlink transmission opportunity based at least in part on determining that the content includes the content for the UE.

Abstract
Techniques are described herein for using a signal to wake up a user equipment (UE) that is in a low-power mode in a synchronized wireless communication system operating a shared radio frequency spectrum band. Once a base station wins a contention for a transmission opportunity in the shared radio frequency spectrum band, the base station may transmit a single signal before the transmission opportunity. After receiving the signal, the UE may begin monitoring for control information (e.g., control resource sets) associated with slots in the transmission opportunity. If the control information indicates that the content of the slot is for the UE, the UE may monitor the slot for its content.

14. A method for wireless communication at a base station, comprising:
-
identifying information to be transmitted to a user equipment (UE); identifying a transmission opportunity to transmit the information to the UE using a synchronized communication system operating in a shared spectrum frequency band; transmitting a signal when the UE is in a second power mode higher than a first power mode of the UE at one of a plurality of potential locations before the transmission opportunity as part of a listen-before-talk (LBT) procedure; and transmitting a downlink transmission burst when the UE is in a third power mode, the downlink transmission burst comprising one or more slots based at least in part on transmitting the signal, wherein the third power mode is higher than the first power mode and the second power mode. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. An apparatus for wireless communication at a user equipment (UE), comprising:
-
a processor; memory in electronic communication with the processor; and instructions stored in the memory and executable by the processor to cause the apparatus to; enter a first power mode of the UE in a synchronized communication system operating in a shared spectrum frequency band; perform, in a second power mode, discontinuous monitoring of a plurality of potential locations for a signal, wherein the second power mode is higher than the first power mode; receive the signal in one of the plurality of potential locations; enter a third power mode, based at least in part on receiving the signal, to process a control resource set associated with a downlink transmission opportunity, wherein the third power mode is higher than the first power mode and the second power mode; determine that a content of the downlink transmission opportunity will include content for the UE based at least in part on processing the control resource set; and monitor at least a portion of the downlink transmission opportunity based at least in part on determining that the content includes the content for the UE. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
