Abstract: Certain aspects of the present disclosure provide techniques for multi-universal subscriber identification module (USIM) and dual connectivity operation. A method performed by a user equipment (UE) includes establishing a first access link, associated with a first SIM of the UE, for communicating with a first base station; establishing a second access link, associated with the first SIM of the UE, for communicating with a second base station; establishing a third access link associated with a second SIM of the UE; determining a need for reduced capability on the second access link to communicate on the third access link; transmitting an indication of the need for the reduced capability to the second base station; and communicating on the third access link using the second SIM simultaneously with communicating on the second access link using the first SIM, wherein communicating on the second access link is at the reduced capability.

Abstract: This disclosure provides systems, methods and apparatuses, including computer programs encoded on computer storage media, for uplink switching for enhanced mobility. In some aspects, this disclosure provides techniques for potentially reducing or eliminating service interruptions experienced during a handover from a source cell to a target cell. Additionally, this disclosure provides techniques for potentially simplifying or improving uplink communications while a UE is connected to both the source cell and the target cell during the handover. This disclosure further provides techniques for potentially reducing UE power consumption or improving uplink resource utilization during a handover from a source cell to a target cell while a UE is connected to both the source cell and the target cell during the handover.

Abstract: Aspects described herein provide designs to reduce the probability of persistent PF/PO conflicts of different subscriptions for a multi-SIM/USIM UE. A base station may be configured to determine a first conflict avoidance PO based on one or more modified parameters associated with the first conflict avoidance PO. The base station may be further configured to transmit a first paging message in the first conflict avoidance PO in a first DRX cycle. A UE may be configured to receive the one or more modified parameters in SIB. The UE may be configured to determine the first conflict avoidance PO based on the one or more modified parameters. The UE may be further configured to receive the first paging message in the first conflict avoidance PO in the first DRX cycle.

Abstract: This disclosure provides systems, methods and apparatus, and computer programs encoded on computer storage media, for managing paging monitoring by a wireless device. In one aspect, the wireless device may receive a serving cell signal from a cell. The wireless device may determine a delay time based on the serving cell signal. The wireless device may monitor for the paging signal during the determined delay time. The wireless device may stop the monitoring for the paging signal upon or after expiration of the determined delay time. In some aspects, the wireless device may receive an indication of multiple paging signal monitoring occasions from the cell, which may include an indication of a number of synchronization signal blocks (SSBs) to be transmitted from the cell and a number of physical downlink control channel (PDCCH) monitoring occasions per SSB in a paging occasion.

Abstract: Certain aspects of the present disclosure provide techniques for high priority data scheduling in uplink bursts. Aspects provide a method that may be performed by a user equipment (UE). The method generally includes receiving one or more uplink grants scheduling a plurality of transmission occasions for the UE. The method generally includes performing a listen-before-talk (LBT) procedure to attempt to acquire a channel for transmitting in at least one of the plurality of transmission occasions. The method generally includes determining one or more of the plurality of transmission occasions to transmit data based, at least in part, on the LBT procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network device may determine that a ping-pong condition is satisfied with regard to a Long Term Evolution (LTE) radio access technology (RAT) and a New Radio (NR) RAT. The network device may configure a dual connectivity mode for the UE based at least in part on the ping-pong condition being satisfied. The network device may cause the UE to deprioritize the NR RAT based at least in part on the ping-pong condition being satisfied. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication. A user equipment (UE) may acquire a triggering synchronization signal block (SSB), which enables the UE to monitor for a floating Type-2 physical downlink control channel (PDCCH) and to determine a subset of paging occasions (POs) to monitor. Or, the UE may monitor for a fixed Type-2 PDCCH, where the UE does not require a triggering signal to monitors POs. In another aspect, the UE may monitor for a paging transmission during a monitoring period. The UE may determine the monitoring period based on received signaling. The UE may receive the signaling, during the monitoring period, indicating that the monitoring period is to be ended before a scheduled end of the monitoring period. In this way, the UE may support a continuity requirement associated with downlink reference signaling (DRS) and may support reception of paging in a shared channel.

Abstract: Wireless communications systems and methods related to DL control message monitoring are provided. A first wireless communication device monitors for a downlink control message from a base station during a first monitoring duration. Additionally, the first wireless communication device monitors for a network activity indication signal from the base station during the first monitoring duration. The first wireless communication device detects the network activity indication signal based on the monitoring of the network activity indication signal. The first wireless communication device switches from the first monitoring duration to a second monitoring duration for the monitoring of the downlink control message in response to detecting the network activity indication signal.
