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.

Abstract: Wireless communications systems and methods related to channel congestion estimations based on virtual collision metrics are provided. A user equipment (UE) may select a plurality of resources from a sidelink resource pool. The UE may request an evaluation of an availability of the plurality of resources and may receive an indication of the availability of the plurality of resources. The UE may further transmit, based on a virtual collision metric associated with the indication of the availability of the plurality of resources, a first sidelink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit a first sidelink control information (SCI) message associated with a sidelink transmission from the first UE, the first SCI message including a first indication of a set of resources reserved for retransmissions of the sidelink transmission at one or more retransmission occasions. The first UE may identify a second SCI message associated with the first SCI message, the second SCI message including one or more time domain resource allocation (TDRA) field values indicative of at least a first subset of the set of resources and a release of the at least first subset of the set of resources reserved for the retransmissions of the sidelink transmission, the release pertaining to at least one retransmission occasion of the one or more retransmission occasions. The first UE may then transmit fewer retransmissions of the sidelink transmission in accordance with the release.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a group of transmission reception points (TRPs) in a coordinated multi-point (CoMP) system. The UE may transmit information associated with measurements between the UE and a TRP of the group of TRPs. The UE may receive, based at least in part on transmitting the information associated with measurements between the UE and the TRP, an indication of resources for a first CoMP cluster of the CoMP system. The UE may communicate with the TRP via a resource pool of the TRP based at least in part on the indication of resources.

Abstract: A method is presented. The method includes organizing a scene as a number of bounding volumes in a hierarchical data structure. The method also includes generating a grid based on the hierarchical data structure. The method further includes mapping each node of the hierarchical data structure to at least one cell of the grid. The method additionally includes identifying a cell of the grid corresponding to an initial intersection location of a ray and the scene. The method still further includes determining a non-root node of the hierarchical data structure as a start node for traversing the hierarchical data structure based on the identified cell. The method also includes traversing the hierarchical data structure starting from the start node to identify a number a primitives intersected by the ray.

Abstract: A first apparatus may be configured to generate a scheduling request to request to transmit at least one of data or control information on a sidelink channel. The first apparatus may be further configured to transmit, to another UE, the scheduling request on resources of a channel configured to carry feedback responsive to transmissions on the sidelink channel. A second apparatus may be configured to monitor resources on a channel for transmissions from other UE, the channel being configured to carry feedback from the other UE responsive to transmissions on a sidelink channel. The second apparatus may be further configured to receive at least one scheduling request from at least one of the other UE on the resources of the channel configured to carry the feedback based on monitoring the resources on the channel.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may transmit a polling request to a receiving device in sidelink control information that is associated with a sidelink data transmission. The polling request may be included in a sidelink control information message or in a medium access control layer message. The receiving device may respond to the polling request with an indication of whether there is data available for transmission to the transmitting device at the receiving device. The transmitting device may determine whether to schedule reverse sidelink resources for the receiving device to transmit the available data based on the response to the polling request.

Abstract: Methods, systems, and devices for wireless communication are described. In a system with high reliability and low latency targets, base station control can be dynamically configured. In some systems, a semi-static split with a greater duration for communications between a controller and one or more associated sensor/actuators than a duration for communications between the controller and base station can be used. In some embodiments, an interrupt can be used to allow for base station control.

Abstract: Certain aspects of the present disclosure provide techniques for autonomous reference signal transmission configuration. Certain aspects provide a method of receiving a configuration message from the base station, wherein the configuration message comprises an indication of a set of candidate resources for transmitting the reference signal. Certain aspects provide a method of detecting a future downlink transmission from the base station, and other aspects provide a method of transmitting, in response to detecting the future downlink transmission, the reference signal utilizing a first resource of the set of candidate resources prior to receiving the future downlink transmission via a second resource in the set of candidate resources.
