Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a message indicating that a base station supports allocating resources for sidelink communications using a first radio access technology (RAT) and a second RAT that is different from the first RAT. The UE may transmit a sidelink information message to the base station using the first RAT that indicates that sidelink communications are to be performed using either the second RAT or both the first RAT and the second RAT. The UE may receive a configuration message from the base station that comprises an identifier for the sidelink communications and an indication of available sidelink resources. The UE may transmit, based at least in part on the configuration message, a request for resources within the available sidelink resources, the request indicating the identifier and a buffer status report (BSR).

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE), e.g., such as a pedestrian UE (PUE), may detect, during a first transmission period of a discontinuous transmission cycle, a transmission over a sidelink channel from a second UE that is located within a threshold distance from the first UE, the first UE associated with a first identifier. The first UE may determine, based at least in part on the transmission, a second identifier associated with the second UE, the second identifier being different from the first identifier. The first UE may use, based at least in part on the second UE being within the threshold distance, the first identifier and the second identifier during one or more subsequent transmission periods of the discontinuous transmission cycle.

Abstract: A method or apparatus for wireless communication at a wireless device. The wireless device transmits or receives an indication of support for using a set of remaining physical resource blocks (PRBs) in a resource pool including one or more sub-channels having an equal number of PRBs and the set of remaining PRBs that are not in the one or more sub-channels having the equal number of PRBs. The wireless device transmits or receives sidelink communication in the set of remaining PRBs.

Abstract: Techniques and apparatus for zone-based soft resource partitioning for high reliability high range communications (HRHRC) are described. A first wireless device determines, based at least in part on a location of the first wireless device and a type of traffic associated with the first wireless device, whether to use a first set of resources or a second set of resources for communications between the first wireless device and a second wireless device. The first wireless device communicates with the second wireless device on the first or second sets of resources, in accordance with the determination. The communications involve the type of traffic.

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: Wireless communication systems and methods related to sidelink communications are provided. A first user equipment (UE) determines a discontinuous operation configuration that indicates an on-duration period for a sidelink communication and a cycle of discontinuous operation. The first UE communicates with at least one other UE during the on-duration period indicated by the discontinuous operation configuration. The first UE uses a base configuration and an on-duration parameter, an offset parameter, and a cycle parameter to determine a discontinuous operation configuration for the first UE.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive situational information for a second wireless device over a first communication link between the first wireless device and the second wireless device and situational information for a third wireless device over a second communication link between the first wireless device and the third wireless device. The first wireless device may transmit message with guidance information to the second wireless device on behalf of the third wireless device and based on the second wireless device and the third wireless device having an event likelihood above a threshold. The event likelihood may be based on the situational information for the second wireless device and the situational information for the third wireless device.

Abstract: Aspects described herein relate to transmitting, to at least one base station, at least one indication of a capability to simultaneously transmit using two different radio access technology (RAT) sidelinks over respective frequency bands. An indication of resources, corresponding to a first RAT sidelink of the two different RAT sidelinks, to exclude in assigning first resources, corresponding to a first RAT sidelink of the two different RAT sidelinks, can also be transmitted to the at least one base station or a second base station. One or more resource grants assigning at least one of the first resources for transmitting using the first RAT sidelink of the two different RAT sidelinks or second resources for transmitting using the second RAT sidelink of the two different RAT sidelinks can be received from the at least one base station or the second base station.

Abstract: Improvements may be made for an apparatus performing congestion control considering different technologies, types of radio resources, and priorities of different packets. The apparatus may be a UE. The UE determines a channel busy ratio (CBR). The UE determines one or more channel resource utilization limits based on the CBR, where each channel resource utilization limit of the one or more channel resource utilization limits corresponds to a respective packet priority. The one or more channel resource utilization limits are also a function of a CBR limit. The UE controls transmission of a plurality of packets based on the one or more channel resource utilization limits, and each packet of the plurality of packets has a respective packet priority.
