Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for maintaining simultaneous connection with a network in dual-active protocol stack (DAPS) handover (HO), such as, for example, in packet data convergence protocol (PDCP) duplication applications that require a user equipment (UE) to maintain up to four simultaneous connections with the network, such as in an multi-radio access transfer (RAT) dual connectivity (MR-DC) to MR-DC HO. In some embodiments, the UE is configured during various phases of a DAPS HO. In some other embodiments, the UE may be configured for multi-TRP operations.

Abstract: Certain aspects of the present disclosure are directed to a method for wireless communication. The method generally includes receiving at least one first packet of a sequence of packets from a source cell, the at least one first packet being dependent on at least one second packet of the sequence of packets for decoding, performing a handover from the source cell to a target cell, determining that the at least one second packet of the sequence of packets was not received from the source cell, generating a message requesting a retransmission from the target cell for the at least one first packet and the at least one second packet based on the determination, and transmitting the message to the target cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless serving node may determine mobility history information associated with the wireless serving node, wherein the mobility history information is associated with a relative mobility between the wireless serving node and one or more reported cells; and transmit, to a child node of the wireless serving node, the mobility history information associated with the wireless serving node. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques communicating in a wireless network. In one embodiment, a method includes monitoring for a paging downlink control channel comprising downlink control information, wherein the downlink control information comprises a first short message; processing the first short message; determining if the control information further comprises scheduling information; processing the scheduling information if the downlink control information comprises scheduling information and the UE is not in a connected state; and ignoring the scheduling information if the downlink control information comprises scheduling information and the UE is in a connected state.

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.
