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.

Abstract: This disclosure provides systems, methods and apparatuses for channel load-based cell reselection procedures. In one aspect, a user equipment (UE) may identify a channel load and may perform a cell reselection procedure based on the channel load. For example, the UE may perform an intra-frequency cell reselection procedure, an inter-frequency cell reselection procedure, or an inter-radio access technology (RAT) cell reselection procedure.

Abstract: This disclosure provides systems, methods and apparatus for determining a target base station timing advance value between a user equipment (UE) and target base station in connection with a random access channel (RACH)-less handover procedure. In one aspect, the UE may determine the target base station's timing advance based at least in part on a timing difference between the target base station and the source base station and based at least in part on a timing offset associated with an uplink and a downlink of the UE. In some aspects, the target base station may determine the timing advance using an uplink reference signal of the UE. In some aspects, the UE may report a timing difference between the target base station and the source base station, and the source cell may determine a timing advance based at least in part on the timing difference.
