Abstract: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) with concurrent sidelink and network link connections to operate the sidelink connection in accordance with a configured behavior associated with a bandwidth part (BWP) operation mode on the network link. The UE behavior may include, for example, no impact on sidelink activity when the network link is in a dormant or network energy saving (NES) mode, discontinuation of sidelink operation when the BWP is configured with a dormant or NES operation mode, or sidelink operation only in an identified sidelink mode when the BWP is configured with a dormant or NES operation mode. The sidelink operation mode based on NES mode of a network link BWP may be signaled to the UE on a per-BWP basis, or based on configuration and separate indication when a BWP is enabled.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may transmit first uplink reference signals in a first time slot. The mobile station may transmit an uplink communication with a frequency domain resource allocation different than a frequency domain resource allocation for the first uplink reference signals. The mobile station may determine a time gap between the transmitted uplink communication and second uplink reference signals to be transmitted in a second time slot and retune the mobile station during the time gap such that the second uplink reference signals maintain phase continuity with the first uplink reference signals. The mobile station may transmit the second uplink reference signals in the second time slot. The first time slot and the second time slot may be consecutive time slots for uplink reference signals. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A device may receive signaling including a channel state information (CSI) reporting configuration. The device may determine one or more resources of a physical uplink channel for aperiodic CSI reporting based on the CSI reporting configuration and transmit an aperiodic CSI report over the physical uplink channel based on the on the one or more resources. In some examples, the device may also determine a set of demodulation reference signal (DMRS) symbols associated with a hop of a set of hops in a time domain or a frequency domain, and coherently transmit, based on the determining, the set of DMRS symbols associated with the hop of the set of hops.

Abstract: Methods, systems, and devices for preconfigured reference signal resources for secret key extraction are described. In some examples, a user equipment (UE) may identify a set of resources reserved for a secret key derivation process including an exchange of reference signals between the UE and a first wireless device using the set of resources. As such, the UE may transmit a first reference signal to the first wireless device using the set of resources and may receive a second reference signal from the first wireless device in accordance with the secret key derivation process. The UE may estimate a communications channel between the UE and the first wireless device and may determine the secret key based on the communications channel in accordance with the secret key derivation process. Accordingly, the UE may communicate with a selected wireless device over the communications channel using wireless communications secured using the secret key.

Abstract: Wireless communications systems may support flexible waveform configuration for autonomous uplink transmissions. A base station may transmit broadcast signaling (e.g., a system information block (SIB)) indicating waveform configuration information for an autonomous uplink transmission by a user equipment (UE). In some cases, the broadcast signaling may include a waveform configuration field (WCF) that may indicate whether flexible waveforms for autonomous uplink are supported, may configure a waveform type, may indicate waveform configuration mapping rules, etc. As such, a UE may identify whether flexible waveform configuration for autonomous uplink is supported, and may determine waveform types for autonomous uplink transmissions based on waveform type configuration information from a base station (e.g., which may include an indication of whether flexible waveform configuration is supported, an indication of waveform type/scenario mapping rules, etc.), one or more LUTs, identified autonomous uplink scenarios, autonomous uplink transmission parameters, or some combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an initial physical uplink control channel (PUCCH) repetition, of a plurality of PUCCH repetitions, on a first component carrier of a plurality of component carrier for which PUCCH switching is enabled. The UE may select a second component carrier, of the plurality of component carriers for which PUCCH switching is enabled, that is to be used for transmitting a second PUCCH repetition of the plurality of PUCCH repetitions. The UE may transmit the second PUCCH repetition on the second component carrier. Numerous other aspects are provided.

Abstract: Aspects are provided which allow a UE configured with PUCCH repetitions to determine, in response to an indication from a base station to switch carriers for PUCCH transmissions, which CCs of a PUCCH group are configured for PUCCH repetitions, when CCs are configured for PUCCH repetitions, what resources in CCs are configured for PUCCH repetitions, and/or how to count PUCCH repetitions in configured CCs. For instance, the UE may receive a PUCCH configuration from a base station indicating PUCCH repetitions, receive an indication from the base station to switch between CCs in a PUCCH group for PUCCH transmissions, and determine at least one of the following configured by the base station: a subset of the CCs for the PUCCH repetitions, a time pattern of the CCs for the PUCCH repetitions, a resource allocation for each of the PUCCH repetitions, or a count for each of the PUCCH repetitions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling from a base station including a configuration for multiple transmission time intervals (TTIs) including uplink symbols, downlink symbols, flexible symbols, or a combination. The UE may receive a grant scheduling one or more repetitions of an uplink shared channel carrying an uplink random access message from the base station. The UE may determine available TTIs for the repetitions based on a pre-TTI evaluation of symbols according to a rule that defines types of symbols available for the uplink shared channel. The UE may transmit the repetitions on the available TTIs according to the rule.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a grant scheduling repetition-based system information block transmissions for the UE, the grant indicating a mapping configuration identifying time-frequency resources for a second repetition of a system information block transmission relative to a first repetition of the system information block transmission. The UE may receive, in a first subset bandwidth of a system bandwidth, the first repetition of the system information block transmission according to the grant. The UE may receive, in a second subset bandwidth of the system bandwidth, the second repetition of the system information block transmission according to the grant and based at least in part on the mapping configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may transmit a set of spatially multiplexed synchronization signals in a same symbol period. The set of spatially multiplexed synchronization signals may indicate a parameter, such as a cell identifier, for the network entity. The network entity may select a sequence for each synchronization signal of the set. A user equipment (UE) may monitor for the set of spatially multiplexed synchronization signals during the same symbol period. The UE may differentiate each synchronization signal based on a respective sequence used to transmit each synchronization signal. The UE may determine that the set of spatially multiplexed synchronization signals were transmitted by the network entity using multiple antenna ports. The UE may determine the parameter for the network entity based on receiving the set of spatially multiplexed synchronization signals.
