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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first sidelink signal indicating a set of resources that are reserved at the UE for sidelink communications. The UE may perform multiple listen-before-talk (LBT) procedures using respective consecutive slots of the set of resources. The UE may transmit another sidelink signal using a portion of the set of resources following the multiple LBT procedures. The UE may release a remaining portion of the set of resources after transmitting the second sidelink signal. Another UE may receive the first sidelink signal including the indication of the set of resources. The other UE may detect the remaining portion of the set of resources that may be available for the other UE to use for first sidelink communications based on overbooking at the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify that a sidelink communication is to be transmitted by the UE prior to a next sensing results sharing opportunity associated with a collaborative sensing schedule that is associated with resource selection for sidelink communications for a group of UEs that includes the UE. The UE may select resources for the sidelink communication. The UE may transmit the sidelink communication using the resources. Numerous other aspects are described.

Abstract: A first UE may select, based on a resource pool configuration for a sidelink communication, at least one of a first slot in time or a second slot in time of a plurality of slots. The plurality of slots may be associated with DMRS bundling. The first UE may configure, based on the DMRS bundling, at least one of one or more symbols in the first slot in time from a gap symbol to a non-gap symbol or one or more symbols in the second slot in time from an AGC symbol to a non-AGC symbol. The first UE may transmit, to a second UE, an indication of the configuration of the at least one of the one or more symbols in the first slot in time or the one or more symbols in the second slot in time.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a first wireless device may transmit, to a second wireless device, a first signal for probing an energy state of the second wireless device. The first wireless device may monitor for a second, backscattered signal indicating the energy state of the second wireless device and may transmit, to the second wireless device, an indication of resources for harvesting energy based on monitoring for the second, backscattered signal. The first wireless device may transmit, to the second wireless device and over the resources, a third signal distinct from the first signal and associated with harvesting energy.

Abstract: Methods, systems, and devices for sidelink configured grant skipping are described. In some examples, a first user equipment (UE) may receive, from a base station, an indication of periodic data resources for a plurality of sidelink data transmissions and an indication of negative scheduling request resources for the first UE to report a skipped sidelink data transmission associated with the plurality of sidelink data transmissions. In some examples, the first UE may transmit, to a second UE, an indication of the skipped sidelink data transmission and may transmit, to a base station, a negative scheduling request using the negative scheduling request resources, where the negative scheduling request may report the skipped data transmissions associated with the plurality of sidelink data transmissions.

Abstract: Base stations of neighbor cells can coordinate with each other in allocating grant-free uplink (GUL) resources for a device-to-device (D2D) connection or channel between user equipments (UEs) across the neighbor cells. The base stations coordinate to determine a condition conducive to D2D communication between the UEs. If the condition exists, the base stations coordinate to allocate network resources for D2D communication between the UEs, and establish a D2D connection between the UEs using the allocated network resources for D2D communication.
