Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a trigger indicating that the UE is to perform a global navigation satellite system (GNSS) acquisition process within a GNSS measurement gap, wherein a start time of the GNSS measurement gap is based at least in part on whether hybrid automatic repeat request (HARQ) feedback is enabled for a channel in which the trigger is received. The UE may perform the GNSS acquisition process within the GNSS measurement gap based at least in part on the trigger. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform measurements on one or more synchronization signals using a low power wake-up radio (WUR) of the UE. For example, the UE may receive first control information associated with a low power synchronization signal. In some examples, the first control information may include a periodicity of the low power synchronization signal and an indication of which measurements to perform on the low power synchronization signals. Based on the first control information, the UE may monitor, using the low power WUR, a resource occasion for the low power synchronization signal. Based on monitoring and receiving the low power synchronization signals, the UE may perform, using the low power WUR, the measurements of the low power synchronization signal. The UE may transmit a report including the measurements of the low power synchronization signal based on performing the measurements.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, via a first serving cell, a radio resource control (RRC) message including an indication to activate a second sewing cell. The UE may transmit, via the first sewing cell in response to the RRC message, an RRC response message acknowledging the RRC message.
The UE may identify, within an activation time interval following transmission of the RRC response message and based on the RRC message, a resource for a reference signal associated with time and frequency tracking for the second sewing cell. The UE may then monitor the resource for the reference signal

Abstract: Methods, systems, and devices for wireless communications are described, in which a communication device (e.g., a user equipment (UE), a network entity) may perform carrier aggregation, and cross-carrier scheduling provides that a first carrier may provide scheduling information for one or more other carriers, in which the one or more other carriers may have different discontinuous reception (DRX) configurations than the first carrier. One or more DRX-related timers of different DRX groups may be started or restarted based on a control information reception on the first carrier, or on a different carrier of a different DRX group. Additionally, or alternatively, control information transmissions on the first carrier may be provided based on one or more DRX-related timers that are associated with the first carrier, or that are associated with a carrier of another DRX group than the DRX group of the first carrier, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support dynamic uplink control channel grouping. For example, a user equipment (UE) may receive control signaling indicating multiple uplink control channel groups for the UE, where each uplink control channel group of the multiple uplink control channel groups is associated with a different set of uplink control channel resources. Additionally, the UE may select an uplink control channel group for a component carrier (CC) associated with the UE, where the uplink control channel group is selected in accordance with a detected trigger at the UE. Further, the UE may transmit uplink control information for the CC in accordance with the selected uplink control channel group.

Abstract: Systems, methods, and devices for secondary cell activation using temporary reference signals are provided. In one aspect, a method of wireless communication performed by a user equipment (UE), includes receiving, from a base station (BS) via a first cell, an activation command to activate a second cell different from the first cell, and receiving, from the BS via the second cell during an activation period, a first reference signal different from a synchronization signal block (SSB). The method further includes performing a measurement of the first reference signal, and operating in the second cell based on the measurement. In some aspects, using reference signals different from SSBs may reduce the delay associated with activating the secondary cell.
