Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of parameters associated with a temporary bandwidth part (BWP) switch from a first BWP to a second BWP. The parameters may include a time duration for the temporary BWP switching procedure, a network antenna configuration for the second BWP, transmission parameters for communications scheduled in the second BWP, or a combination thereof. The UE may switch from the first BWP to the second BWP in accordance with the temporary BWP switching procedure and communicate with a network entity using the indicated parameters. For example, the UE may receive one or more downlink messages or transmit one or more uplink messages in accordance with the indicated parameters. Thereafter, the UE may switch from the second BWP to a third BWP in accordance with the temporary BWP switching procedure.

Abstract: Certain aspects of the present disclosure provide techniques for securing physical (PHY) layers in wireless communication. Certain aspects are directed to a method for wireless communication by a user equipment (UE). In some examples, the method includes obtaining a key and using the key during physical layer signal processing of a physical uplink control channel (PUCCH) transmission having more than one symbol to provide security for the PUCCH transmission.

Abstract: This disclosure provides systems, methods and apparatus including computer programs encoded on computer storage media, for a user equipment (UE) to determine and apply limits to physical downlink control channel (PDCCH) processing in a dual active protocol stack handover scenario. In one aspect, the UE utilizes a joint blind decode capability for both a source cell group and a target cell group to determine whether a total limit for PDCCH candidates to monitor or non-overlapped control channel elements (CCEs) to monitor is applicable. The UE may identify a per cell limit for each configured single transmit receive point (TRP) cell and each multiple TRP cell based on a sub-carrier spacing SCS of the cell and the determination. The UE may include an interface configured to obtain a PDCCH for a slot. The UE may perform blind decoding operations on CCEs up to the per cell monitoring limit for each cell.

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 to the UE to apply demodulation reference signal (DMRS) bundling to physical uplink shared channel (PUSCH) transmissions. The UE may maintain phase coherence across multiple PUSCH transmissions, to which the DMRS bundling is applied, to enable joint channel estimation across the multiple PUSCH transmissions. The UE may transmit, based at least in part on the configuration, uplink control information (UCI) that includes a coherence indication. The UE may multiplex the UCI with a PUSCH transmission of the multiple PUSCH transmissions to which the DMRS bundling is applied. The coherence indication may indicate whether the PUSCH transmission is coherent with one or more other PUSCH transmissions, of the multiple PUSCH transmissions, transmitted by the UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described, including techniques for utilizing implicit or explicit signaling to indicate a cancellation of demodulation reference signal (DMRS) bundling. A first user equipment (UE) may perform DMRS bundling across physical sidelink channels transmitted to a second UE to enable the second UE to perform joint channel estimation. In some examples, based on a detected change, either at the first UE or the second UE, the first UE may signal to the second UE that the DMRS bundling is canceled. In some examples, the detected change may be a resource allocation change, a physical channel configuration change, a change in a quasi-colocation (QCL) relationship at the first UE, or a change in a transmission configuration indicator (TCI) state at the first UE. Additionally or alternatively, the first UE or the second UE may request the cancellation based on detected changes.

Abstract: In an embodiment, a UE determines a timing for a serving cell, obtains a location of a non-serving cell, determines a location of the UE, and estimates a timing for the non-serving cell based at least in part on the timing for the serving cell, the location of the non-serving cell and the location of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A configuration for a reference signal used to determine a non-linear behavior of transmission components at a transmitting device may be determined. The configuration for the reference signal may be determined based on signaling transmitted by the transmitting device, signaling transmitted by a device that receives the reference signal, or both. Additionally, or alternatively, the configuration for the reference signal may be determined based on a configuration of other signals transmitted by the transmitting device prior to or concurrently with the transmission of the reference signal. The determined configuration may be used to generate and transmit the reference signal or to determine a configuration of a received reference signal. In both cases, a non-linear response of transmission components at the transmitting device may be determined based on the reference signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, a first control message indicating sets of transmission parameters associated with dynamic transmission parameter adaptation. The UE may receive a second control message including an indication to switch from communicating with the network entity in accordance with a first set of transmission parameters to communicating with the network entity in accordance with a second set of transmission parameters. The UE may communicate one or more messages with the network entity based on a switch, in response to the second control message, from the first set of transmission parameters to the second set of transmission parameters in accordance with a parameter switching timeline for the dynamic transmission parameter adaptation.
