Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a receiving UE may receive an indication of a feedback mode for a set of sidelink or downlink transmissions, and the UE may operate in the indicated feedback mode for the set of sidelink or downlink transmissions. In some examples, the operating modes may include hybrid automatic repeat request (HARQ) feedback, negative acknowledgment only feedback, acknowledgement only feedback, or no feedback. In some examples, a default feedback mode may be configured, and the receiving UE may receive an indication to use a different feedback mode for a given set of sidelink or downlink transmissions. The receiving UE may revert to the default feedback mode after the set of sidelink or downlink transmissions. In some examples, different feedback modes may be associated with different sets of resource pools, semi-persistent scheduling indices, component carriers, or bandwidth parts.

Abstract: In an aspect, a UE measures interference from one or more neighbor base stations on a set of resources over a period of time, and determines an interference burst dynamic associated with the set of resources based on the measured interference over the period of time. The UE transmits an interference measurement report comprising an indication of the interference burst dynamic to a serving base station of the UE. The serving base station performs at least one action based in part upon the prediction.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a UE may determine a power control adjustment based on sidelink messages received from other UEs. The UE may transmit, to the other UEs, an indication of the power control adjustment to the other UEs. The other UEs may transmit additional sidelink messages in accordance with the power control adjustment, such that power levels of the additional sidelink message satisfy a threshold. A base station may indicate a power control adjustment to one or more UEs. For example, the base station may receive power control information associated with sidelink communications between a set of UEs. The base station may transmit an indication of a power adjustment parameter for a transmit power level for sidelink messages transmitted between two UEs of the set. The value of the power adjustment parameter may be based on the received power control information.

Abstract: Methods, systems, and devices for wireless communication are described. Devices may synchronize parameters associated with an encryption key to avoid a key mismatch. In a first example, a transmitter and a receiver may each update a respective parameter at each transmission occasion associated with semi-statically allocated resources, regardless of whether signaling is transmitted in the transmission occasion. In a second example, the transmitter and the receiver may each update the respective parameter based on a slot count, rather than at each transmission occasion. In a third example, the transmitter may indicate a value of a transmitter parameter to the receiver, for example in control signaling or in the signaling in each transmission occasion. In a fourth example, the receiver may be enabled to identify a skipped transmission occasion The receiver may be enabled with a feedback process to indicate the receiver recognized the associated transmission occasion was skipped.

Abstract: The base station may transmit, to a UE, a configuration of a set of secure RSs for each CC of a set of CCs and at least one RE, and instruct the UE to select a subset of CCs from a set of CCs. The base station and the UE may measure the set of secure RS across the at least one RE, and select the subset of CCs from the set of CCs based on the measurement. The base station and the UE may communicate with each other on the subset of CCs. The base station and the UE may communicate with each other on a first CC of the subset of CCs, and switch the CC from the first CC to a second CC of the subset of CCs to communicate with each other, based on a number of ACKs/NACKs transmitted or a pattern.

Abstract: Methods, systems, and devices for wireless communications are described for relaying communications from a source device to a destination device via one or more relay devices. Scheduled resource grants may be used to provide resources for the relayed communications, and may provide one or more associated relaying parameters for relayed communications. A source device and relay device may use parameters to determine a relaying priority for multiple communications that are to be relayed. Additionally or alternatively, scheduled resource grants may include energy harvesting (EH) parameters for communications that use the scheduled resources. The EH parameters may include, for example, time-switching energy harvesting parameters that configure a first subset of symbols for data and a second subset of symbols for EH, or power-splitting EH where power of a received signal is split between EH components and decoding components.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may generate statistical modeling of sensing outcomes (e.g., may identify one or more measurement statistics), and may transmit values that are quantized based on the one or more measurement statistics. Measurement statistics may include one or more of mean and variance of sensing results (e.g., channel quality measurements such as signal to interference ratio (SIR)), auto-correlation of measurements or measurement statistics over time, auto-covariance, or the like. In some examples, a UE may incorporate channel measurement statistics into a waveform (e.g., the coordination report) or otherwise compress the measurements. The UE may measure its own self-interference, and may indicate (e.g., in the coordination message) resource availability that reflects the measured self-interference. A receiving UE may use the coordination message to schedule subsequent sidelink communications (e.g., with the transmitting UE or with other UEs).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to communicating a first message with a base station in accordance with a first antenna configuration, a first set of resources, or both. The UE may transmit capability signaling indicating a capability of the UE to adjust the first antenna configuration, the first set of resources, or both, for channel reliability management. The UE may receive, based on the capability signaling, control signaling indicating one or more parameters for channel unreliability event detection associated with a downlink channel between the base station and the UE. The UE may then communicate a second message with the base station in accordance with a second antenna configuration, a second set of resources, or both, based at least in part on a channel unreliability event detected in accordance with the one or more parameters.

Abstract: Methods, systems, and devices for wireless communication are described. A first wireless device may establish a sidelink communications link with a second wireless device. The first wireless device may transmit, to the second wireless device, an indication of a capability to support a configuration for phase continuity between multiple physical channel transmissions of the sidelink communication link. The first wireless device may transmit one or more physical channel transmissions, which each may be associated with a set of one or more demodulation reference signals (DMRSs) to the second wireless device in accordance with the indicated configuration for phase continuity between the physical channel transmissions. The second wireless device may determine channel parameters associated with the one or more physical channel transmissions based on a joint channel estimation associated with the one or more sets of DMRSs.
