Abstract: Various aspects to reduce interferences in presence of a reconfigurable intelligent surface (RIS) are provided. In an aspect, a first device perform a first transmission using a first set of beams of the first device in response to an activated RIS for serving a second device to facilitate communication between the first device and the second device not being present. The first device may further perform a second transmission using a second set of beams of the first device in response to the activated RIS being present, the second set of beams being a subset of the first set of beams that excludes one or more beams of the first set of beams.

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, an indication that a plurality of physical downlink shared channel (PDSCH) communications are associated for purposes of demodulation reference signal bundling. The UE may determine whether a phase continuity is to be maintained for the plurality of PDSCH communications based at least in part on respective quasi-co-location assumptions for the plurality of PDSCH communications. The UE may process the plurality of PDSCH communications based at least in part on whether the phase continuity is to be maintained Numerous other aspects are provided.

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: Disclosed are techniques for wireless communication. In an aspect, BS determines a channel state information (CSI) report field priority-based security scheme, and transmits CSI report field priority-based security scheme to UE. UE determines bit availability in CI (e.g., UCI or SCI or MAC CE) for transmission of a CSI report. UE configures, based on the CSI report field priority-based security scheme and the CI bit availability, the CSI report with first field(s) (e.g., secured with key) being secured via a key and second field(s) being unsecured (e.g., not secured with any key or secured with weaker key below strength threshold). UE transmits the CSI report to BS.

Abstract: Techniques for indicating system information block or paging waveforms for future communications may include a user equipment (UE) configured to identify a waveform configuration of a downlink (DL) signal including system information to be received from a base station during a random access channel (RACH) procedure in response to an indication of the waveform configuration of the DL signal. The UE may also be configured to receive, from the base station, the system information in response to the waveform configuration of the DL signal being identified.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure one or more transmission parameters to maintain a channel consistency for a transmission channel. The UE may transmit, via the transmission channel, a set of multiple communications using the one or more transmission parameters. 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 a preemption indication indicating that resources of at least one shared channel communication among one or more shared channel communications of a shared channel are to be preempted, where the one or more shared channel communications are to be time-domain reference signal (RS) bundled based at least in part on an RS associated with the shared channel. The UE may selectively perform time-domain RS bundling of the one or more shared channel communications based at least in part on the preemption indication. Numerous other aspects are provided.

Abstract: Aspects are provided which allow a first device to secure transmission of polar encoded control information by encoding at least a portion of frozen bits and/or information bits with a shared key with a second device before these bits are encoded by a polar encoder. The first device determines whether to encode at least one of a plurality of frozen bits or a plurality of information bits using the shared key. Based on the determination, the first device encodes the frozen bits and/or the information bits, and sends the encoded frozen bits and/or the encoded information bits to the second device. Since the receiving device has the shared key, the receiving device may successfully decode the control information, while an eavesdropper who receives the encoded bits may fail to decode the control information due to lack of knowledge of the shared key.

Abstract: Wireless positioning accuracy of a user equipment (UE) is impacted by locations of the transmit/receive points (TRPs) and UE for wireless positioning. To improve the accuracy of estimated locations, a geometric dilution of precision (GDOP) may be determined for different groups of candidate TRPs, with the GDOP indicating a potential positioning error associated with the group of candidate TRPs. A UE may determine GDOPs for different combinations of candidate TRPs. One or more devices of a wireless network (e.g., a location server and/or a UE for positioning) may select or exclude one or more candidate TRPs from being used for wireless positioning of a UE based on the determined GDOPs. Exclusion or selection of candidate TRPs for wireless positioning may also be based on quality measurements of PRSs (such as an RSRP or SNR) or a time duration associated with measuring the PRSs from the candidate TRPs to be selected.

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, one or more downlink reference signals. The UE may transmit, to the base station, a random access channel (RACH) message associated with a RACH procedure using a first RACH configuration that is associated with repetitions or a second RACH configuration that is not associated with repetitions based at least in part on whether a measurement of the one or more downlink reference signals satisfies a measurement threshold, wherein a selection of a RACH configuration is evaluated by the UE prior to a transmission of an initial message associated with the RACH procedure. Numerous other aspects are described.
