Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for sidelink feedback power control. The UE may transmit a sidelink feedback transmission, in accordance with the configuration, using a transmit power that is based at least in part on at least one of: a quantity of resource blocks (RBs) associated with the sidelink feedback transmission, a quantity of symbols associated with the sidelink feedback transmission, a sidelink pathloss value, or a size of the sidelink feedback transmission.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may transmit feedback signaling for received sidelink messages to both the base station and the transmitting UE. The receiving UE may multicast a feedback message to both the base station and the transmitting UE on a physical uplink control channel (PUCCH) or on a physical sidelink feedback channel (PSFCH). The base station may configure the receiving UE with resources, the transmitting UE may allocate resources to the receiving UE, or the base station may actively monitor for the feedback message. In some examples, the receiving UE may operate in a dual connectivity mode, and may transmit the feedback message to both the base station and the transmitting UE on both the PUCCH and the PSFCH.

Abstract: Methods, systems, and devices for wireless communications are described. A first device, which may be a user equipment (UE), may transmit a sidelink control information SCI) message (e.g., an SCI-1 message) on a physical sidelink control channel (PSCCH) to a group of devices. The SCI may message may reserve a set of sidelink resources for a sidelink communication between the first device and a second device of the group of devices. The first device may receive an acknowledgment (ACK) message on a physical sidelink feedback channel (PSFCH) from the second device. Based on receiving the ACK message, the first device may release the set of sidelink resources and may transmit a release message (e.g., a physical sidelink release channel (PSRCH) message) on a PSRCH that includes an indication of the released set of sidelink resources.

A first UE may receive, from a second UE such as a PLC, sidelink control information scheduling a first transmission to be transmitted by the first UE to the second UE on a first set of resources in a dedicated resource pool for sidelink control signaling. The first UE may receive an indication that a second transmission is scheduled to be transmitted by the first UE on a second set of resources which at least partially overlaps in time with the first set of resources. The first UE may transmit at least one of the first transmission or the second transmission in accordance with a conflict resolution rule based on the second set of resources at least partially overlapping with the first set of resources.

Abstract: Methods, systems, and devices for wireless communications are described to support half-duplex-aware resource selection in sidelink. A physical (PHY) layer at a user equipment (UE) may report available resources to a medium access control (MAC) layer excluding some resources on which the UE is scheduled to receive or other UEs are scheduled to transmit. Specifically, the PHY layer may exclude resources on which the UE is scheduled to receive from a set of resources available for a sidelink transmission from the UE. Similarly, the PHY layer at the UE may exclude resources on which other UEs are scheduled to transmit from a set of resources available for a sidelink transmission to those UEs. A MAC layer at the UE may indicate to the PHY layer (e.g., directly or indirectly) the resources to be excluded when reporting available resources.

The receiving UE may receive a configuration of multiple resource pools for sidelink communications. The transmitting UE may transmit at least two repetitions of a sidelink control information (SCI) on at least two of the multiple resource pools. Each repetition of the SCI includes a reservation for a physical sidelink shared channel (PSSCH) on a respective resource pool. The receiving UE may perform soft combining on the at least two repetitions of the SCI to determine resources for the PSSCH. The receiving UE may decoding the PSSCH based on the SCI, for example, by combining multiple repetitions of the PSSCH on the reservations indicated by the SCI.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may transmit to a network entity a first signal requesting a modification of allocated resources for sidelink transmission, sidelink reception, or both based on multiple transport blocks (TBs) for communication for the UE. The UE may receive, from the network entity, a downlink control information (DCI) signal granting one or more resources to the UE for sidelink communications based on the first signal. In some cases, the DCI signal may dynamically or periodically grant one or more resources for sidelink transmission, one or more resources for sidelink reception, or both for the UE. The UE may use the granted resources to communicate multiple TBs with one or more other UEs based on the DCI signal. For example, a single DCI message may allocate resources for sidelink communication of multiple TBs.

Abstract: Aspects of the present disclosure provide techniques that help reducing transmission overhead related to sidelink control information (SCI). For example, when a transmitter UE has established a sidelink communication with a receiver UE, the transmitter UE may schedule with at least one semi-persistent scheduling (SPS) process at a first time interval. The transmitter UE may sense whether a resource is available for transmissions to the receiver UE based on decoding an SCI, such as an SCI 0-1 message. The SCI is transmitted at a second time interval that is greater than the first time interval. For example, the second time interval may be a multiple of the first time interval of the at least one SPS process. The second time interval may be flexible and may be increased to reduce the number of SCI messages transmitted in certain time periods in order to reduce communication overhead.

Abstract: Methods, systems, and devices for wireless communications are described. Described techniques provide for signaling for configuring energy scheduling requests or communications scheduling requests from a semi-passive user equipment (UE) to the network.

The network entity may transmit control signaling indicating a configuration for the UE to transmit energy scheduling requests or communications scheduling requests. The UE may transmit an energy scheduling request or communications scheduling request in accordance with the configuration. In response to an energy scheduling request, the network entity may indicate a resource for an energy transfer signal, and the UE may monitor for and receive an energy transfer signal in the indicated resource. In response to a communications scheduling request, the network entity may indicate a resource for a data transmission.

Abstract: Positioning of one or more user equipments (UEs) is performed using broadcast common sounding reference signals (SRS) resources for positioning. The common SRS that is broadcast by a UE is received and measured by one or more base stations and one or more other UEs. The other UEs may have known positions and may server as anchor nodes for positioning. The other UEs may have known positions and may serve as a positioning (anchor) node or may have unknown positions and may be jointly positioned with the target UE. During joint positioning, each of the other UEs may similarly broadcast a common set of SRS that is received and measured by the base stations and other UEs for positioning. An angular measurement of the SRS broadcast by one or more UEs may be measured and used to resolve minor symmetry in positioning solutions.
