Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may encode a sequence associated with an acknowledgement status using a symmetric key. The symmetric key may be determined using channel reciprocity at a physical layer or may be determined using a higher layer of the UE. Accordingly, the UE may transmit the sequence associated with the acknowledgement status. Numerous other aspects are described.

Abstract: Aspects of the present disclosure are directed to techniques for enhancing security of wireless communications; specifically, physical (PHY) level communications. In some examples, the disclosure is directed to a user equipment (UE) configured to receive, from a base station, a configuration including a key extraction mode. In certain aspects, the UE may transmit a sounding reference signal (SRS) to the base station. In certain aspects, the UE may receive a signal from the base station in response to the SRS, wherein, in response to the key extraction mode, the signal is precoded based on a key. In certain aspects, the UE may extract the key from the signal.

Abstract: Aspects are provided which allow a base station to provide CSI report configurations and a UE to provide CSI reports in response to such configurations which account for a power savings mode of the base station. While in the power savings mode, the base station may deactivate one or more of its antenna panels or sub-panels to reduce energy expenditure, for example, while performing dynamic antenna port adaptation. To account for this antenna port deactivation, the base station may send a CSI report configuration to a UE including one or more measurement resource sets associated with the power savings mode. The UE may obtain the CSI report configuration and send a CSI report to the base station in response to a CSI measurement in the one or more measurement resource sets.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with periodic uplink grants that provide a number of repetitions and a redundancy version (RV) sequence for the repetitions. Prior to the start of an uplink grant period, the UE may determine a set of slots that are available for uplink transmissions in the uplink grant period. Based on the set of slots, the UE may determine a corresponding RV for repetitions of the uplink communication associated with each slot. The slots with uplink transmissions within the uplink grant period may be non-contiguous. Repetitions of an uplink communication may be configured to be transmitted across multiple uplink grant periods, which may be triggered based on a threshold value associated with the repetitions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and network entity may perform physical uplink control channel (PUCCH) resource adaptation in order for the network entity to reduce power consumption. For example, the UE may receive first control signaling indicating a first set of PUCCH resource occasions and a second set of PUCCH resource occasions, and transmit one or more uplink messages via the first set of PUCCH resource occasions. In some examples, the UE and the network entity may switch between operating using the first set of PUCCH resource occasions to operating using the second set of PUCCH resource occasions based on second control signaling indicating for the UE to switch between sets of PUCCH resource occasions. In some examples, the second control signaling may indicate for the UE to skip one or more uplink messages or PUCCH resource occasions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a reference signal or channel conveying a paging indicator. The UE may determine, based on the paging indicator, whether to monitor a paging control channel including a scheduling grant for a paging shared channel communication. The UE may estimate time or frequency information for receiving the paging control channel based at least in part on a result of the determining, and receiving the paging control channel containing based at least in part on the result of the determining and the estimated time or frequency information, or skipping monitoring the paging control channel based at least in part on the result of the determining. 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 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.
