Abstract: A first UE may configure, during a COT, an initial transmission and one or more subsequent transmissions that follow the initial transmission. The one or more subsequent transmissions are configured to prevent a release of the COT. Based on the configuration, the first UE may transmit the initial transmission including an indication of the COT and a time period for transmitting the one or more subsequent transmissions. The first UE may subsequently transmit the one or more subsequent transmissions during the indicated time period. A second UE may receive the indication of the COT and the time period where the release of the COT is prevented. The second UE may prepare a packet for transmission during the time period where the release of the COT is prevented and transmit the packet during the COT following the time period where the release of the COT is prevented.

Abstract: A system includes storage compartments, each of the storage compartments being configured to store shipments and having a locking mechanism and a computing system that controls operations of the storage compartments. The computing system performs: receiving a request from a providing entity to reserve a portion of the storage compartments, obtaining identification information of a requesting entity requesting a shipment from the providing entity, generating a scannable code; transmitting the scannable code and the identification code of the requesting entity to the providing entity, determining a compartment of the storage compartments to be reserved to temporarily store the shipment, detecting a scan of the scannable code or an input of the identification code on a computing device at a terminal of a location of or adjacent to the reserved determined compartment, and in response to detecting the scan or the input of the identification code, opening the reserved determined compartment.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from another UE, a coordination message that includes resource information (e.g., a preference status) for communication resources. The UE receiving the coordination message may determine a status of one or more resources based on the resource information, an intended recipient of the coordination message (e.g., based on a destination identifier of the coordination message), or a communication connection associated with the one or more resources. The status may indicate that a respective resource of the one or more resources is available, reserved, preferred, or non-preferred, or some combination thereof. In some examples, the one or more resources may be for a sidelink connection or a unicast connection. The receiving UE may utilize the determined status to select one or more resources for a sidelink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish a unicast connection over a sidelink communications with a second UE. To establish the unicast connection over the sidelink, the first UE may transmit a request message (e.g., a first message) to the second UE, and the second UE may transmit a response message (e.g., a second message) to the first UE accepting the request. The unicast connection over the sidelink may then be established between the first UE and the second UE, and user data may then be transmitted over the sidelink on the established unicast connection. Additionally, the first UE may transmit a connection complete message (e.g., a third message) to the second UE indicating that the unicast connection has been established. The request message, the response message, and the connection complete message may be radio resource control (RRC) messages.

Abstract: Methods, systems, and devices for wireless communications are described. User equipments (UEs) may transmit sidelink control information (SCI) messages indicating reservations for upcoming sidelink transmissions in the same reserved resource. One of the UEs or another UE may detect a collision in the reserved resource based on the SCI messages.

A UE may transmit a collision indication in the calculated feedback channel resource. The UEs that transmitted the SCI messages may monitor the calculated feedback channel resource for a collision indication for the reserved resource.
