Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a master node (MN) may receive a message indicating that a user equipment (UE) has determined that a condition for a conditional primary secondary cell (PSCell) change has been satisfied for a candidate target PSCell. The candidate target PSCell may be one of a set of candidate target PSCells associated with the UE in a conditional PSCell change configuration provided by a base station. The MN may transmit, to a source secondary node, a confirmation message associated with the conditional PSCell change. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive discontinuous reception (DRX) configuration information identifying a slot or sub-slot granularity for transitioning from a non-monitoring state to a monitoring state, wherein the information identifies, for each slot or sub-slot, whether to operate in the non-monitoring state or the monitoring state; and transition from the non-monitoring state, wherein the user equipment (UE) is not performing monitoring, to the monitoring state, wherein the UE is performing monitoring, in accordance with the DRX configuration information. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for multi-universal subscriber identification module (USIM) and dual connectivity operation. A method that may be performed by a user equipment (UE) includes establishing a first access link, associated with a first subscriber identification module (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; identifying at least one time division multiplexing (TDM) pattern indicating a set of time periods during which to use the third access link; and tuning to the third access link for communicating using the second SIM during at least one time period of the set of time periods indicated in the TDM pattern.

Abstract: Wireless communications systems and methods relate to an automatic transmission scheme for a de-prioritized protocol data unit (PDU) when the originally assigned configured grant for the PDU is de-prioritized due to channel conflicts. Specifically, a user equipment may obtain a PDU for transmission over a first configured grant physical uplink shared channel (PUSCH) instance. The UE may then detect de-prioritization information that the first configured grant PUSCH instance is de-prioritized due to channel overlapping, and then automatically transmit the PDU originally associated with the first configured grant PUSCH instance over a second configured grant PUSCH instance.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for encrypting paging information transmitted to a user equipment (UE) in a paging message. In one aspect, a base station (BS) encrypts paging information and transmits a paging message to one of a UE or another BS for transmission to the UE. The paging message includes the encrypted paging information. A UE receives the paging message from a BS including the encrypted paging information. The UE decrypts the encrypted paging information to identify paging information, and determines whether to communicate with the BS based on the paging information. The paging information may be encrypted and the encrypted paging information decrypted based on information configured or obtained during at least one of a registration procedure or a radio access network (RAN)-based Notification Area Update (RNAU). Confidentiality of paging information in paging messages may thereby be improved.

Abstract: Certain aspects of the present disclosure provide techniques for handling a radio link failure timer in the presence of a conditional handover command. A method that may be performed by a user equipment (UE) includes receiving, from a serving cell, a conditional handover command for handing over the UE to a target neighbor cell, wherein the conditional handover command includes one or more triggering conditions for executing a handover to a candidate target cell; monitoring one or more first signals from the candidate target cell for the one or more triggering conditions; and performing one of: stopping a timer based on performing a conditional handover to the target candidate cell; or detecting a timer has expired while monitoring the one or more first signals from the candidate target cell for the one or more triggering conditions.

Abstract: Aspects of the present disclosure describe scrambling of information for wireless communications to prevent deciphering or altering by unintended recipients. An example method may include generating, by a first device, a scrambling key based on at least one of a freshness parameter or a private key. The private key is known by the first device and a second device. The method also includes scrambling a payload based on the scrambling key at a physical layer. A packet includes the payload for wireless transmission from the first device to the second device via a shared channel.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a number of bits to be used in an indication of at least one of a listen-before-talk (LBT) category or a channel access priority class to be used for uplink communications. The UE may receive the indication of at least one of the LBT category or the channel access priority class to be used for a transmission starting point associated with one or more uplink communications, wherein the indication includes the number of bits indicated in the configuration. The UE may perform an LBT procedure for an uplink communication, of the one or more uplink communications, transmitted at the transmission starting point, according to the LBT category or the channel access priority class. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a random access channel (RACH) procedure using a first beam associated with a base station (BS). The UE may transmit, to the BS and during the RACH procedure, an uplink control information (UCI) communication that indexes into a resource set of beams to indicate one or more second beams associated with the BS. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may provide, to a source base station (BS) and prior to a handover of the UE from the source BS to a target BS, information that identifies a set of transition capabilities of the UE. The UE may receive, from the source BS, a handover command or reconfiguration message after providing the information to the source BS. The UE may communicate, using a subset of the transition capabilities, with the target BS prior to the release. Numerous other aspects are provided.
