Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE determines a sidelink resource configuration for a slot, wherein the sidelink resource configuration includes a first set of resources carrying a first PSSCH in a first mini-slot of the slot, a second set of resources carrying a second PSSCH in a second mini-slot of the slot, and a third set of resources carrying a PSFCH associated with one or more PSSCHs of one or more preceding slots. The UE may communicate data over at least a portion of the slot in accordance with the sidelink resource configuration. In some designs, a sidelink management device (e.g., the UE, another UE, or a network component) may transmit the sidelink resource configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a first control resource pool associated with sidelink control signaling during a first sensing window and monitor a portion of a second resource pool associated with sidelink data signaling during a second sensing window. The UE may perform joint resource selection on the first resource pool and the second resource pool based on the monitoring during the first and second sensing windows. The UE may transmit a sidelink control information message including resource indication fields to reserve the selected sidelink control channel resources and selected sidelink shared channel resources. The UE may transmit the sidelink data message on one or more of the reserved sidelink shared channel resources.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing and reporting reference signal received power (RSRP) measurements. In particular, the techniques described herein may allow a user equipment (UE) to efficiently identify reference signals on which to perform RSRP measurements (e.g., based on signaling from a base station), identify when to report RSRP measurements (e.g., aperiodically, periodically, or semi-persistently), and identify a channel on which to report RSRP measurements (e.g., a sidelink channel or an uplink channel). In addition, the techniques described herein may also allow a UE to efficiently identify open loop parameters to use to determine an appropriate transmit power for transmitting to another UE over a sidelink.

Abstract: Methods, systems, and devices for wireless communications at a device are described. The device may receive an indication of a configuration that schedules semi-persistently scheduled resources for transmissions from the first device. The device may also receive an indication of a set of resources available to the first device for requesting a set of the semi-persistently scheduled resources configured for the first device. The device may transmit a message over the set of resources to request the set of semi-persistently scheduled resources.

Abstract: Methods, systems, and devices for wireless communications are described for improving sidelink communication reliability. In some examples, a user equipment (UE) may map allocated sidelink resources from a logical domain to a physical domain, where the mapped resources may include greater frequency diversity in the physical domain. A frequency range of a sidelink control channel or of a sidelink data channel may be greater in the physical domain than in the logical domain after the mapping. In some examples, sidelink communications may be associated with an aggregation factor that represents a number of repetitions of a sidelink communication. In this example, a UE may repeat a sidelink communication within a contention-based resource pool a number of times before receiving feedback in order to increase communication reliability. A first UE may communicate a sidelink communication with a second UE using a resource mapping or repetitions of the sidelink communication.

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. Numerous other aspects are provided.

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 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. Described techniques provide for signaling for configuring energy scheduling requests or communications scheduling requests from a semi-passive user equipment (UE) to the network. A semi-passive UE may transmit a message indicating a UE class type to a serving network entity (e.g., indicating that the UE is a semi-passive UE). 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.
