Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration associated with artificial noise assisted physical layer security for at least one of an uplink channel or a sidelink channel. The UE may receive an indication of a power allocation parameter associated with a power allocation between a data signal and an artificial noise signal. The UE may transmit, via the uplink channel or the sidelink channel, at least one of the data signal or the artificial noise signal with the power allocation between the data signal and the artificial noise signal based at least in part on the power allocation parameter. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information indicating that demodulation reference signal (DMRS) time domain bundling is enabled. The UE may determine a time domain bundling configuration based at least in part on the information indicating that the DMRS time domain bundling is enabled. Accordingly, in some aspects, the UE may perform channel estimation based at least in part on DMRSs received in different physical downlink control channel monitoring occasions based at least in part on the time domain bundling configuration. 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 receive a channel state information (CSI) report configuration indicating a time-domain reference signal bundling configuration assumption for CSI reporting in accordance with the CSI report configuration; and transmit a CSI report based at least in part on the time-domain reference signal bundling configuration assumption.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node and prior to transmission of a radio resource control (RRC) connection request message, a phase tracking reference signal (PTRS) indication that indicates a presence of a PTRS. The UE may transmit the RRC connection request message comprising the PTRS based at least in part on the PTRS indication. Numerous other aspects are described.

Abstract: Aspects relate to wireless communication including the provision of the ability of a user equipment (UE) to indicate the capability of the UE for demodulation reference signal (DMRS) bundling and/or joint channel estimation (JCE). In aspects, the capability indication includes using at least a physical random access channel (PRACH) to indicate the capability of a UE for repeated transmission of the physical uplink shared channel (PUSCH) carrying a connection message, and counting of available slots that are used for the repeated transmission of the physical channel. Additionally, the UE may be configured to indicate the capability for JCE through a demodulation reference signal (DMRS) configuration or a DMRS port.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that an uplink demodulation reference signal (DMRS) bundling operation associated with a physical channel has started. The UE may change an activity state of a reception operation associated with periodic downlink communications based at least in part on determining that the uplink DMRS bundling operation has started. Numerous other aspects are described.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication. The apparatus applies a processing timeline for multiplexing uplink control information (UCI) in at least one slot of a multiple slot physical uplink shared channel (PUSCH) transmission. The apparatus transmits the multiple slot PUSCH transmission with multiplexed UCI based on the processing timeline being satisfied.

Abstract: Aspects of the present disclosure includes methods for transmitting to a source base station associated with a source master cell group (MCG), a physical uplink control channel (PUCCH) repetition in each of one or more slots of the source MCG during a dual active protocol stack (DAPS)-based handover of the UE from the source MCG to a target MCG. The method includes transmitting, to a target base station associated with the target MCG, an uplink transmission in one or more slots to the target base station during the DAPS-based handover. The method includes canceling at least one PUCCH repetition associated with the source MCG, the canceled at least one PUCCH repetition overlapping in time with the uplink transmission to the target MCG. The method further includes performing a counting of PUCCH repetitions based, at least in part, on the cancelation of the at least one PUCCH repetition.

Abstract: Certain aspects of the present disclosure provide techniques for mapping time domain positions for a demodulation reference signal (DMRS). A method that may be performed by a user equipment (UE) includes identifying time domain positions for a DMRS to be transmitted with a transport block (TB) sent across multiple slots and transmitting the TB across the multiple slots with the DMRS in the time domain positions.
