Abstract: Positioning of one or more user equipments (UEs) is performed using broadcast common sounding reference signals (SRS) resources for positioning. The common SRS that is broadcast by a UE is received and measured by one or more base stations and one or more other UEs. The other UEs may have known positions and may server as anchor nodes for positioning. The other UEs may have known positions and may serve as a positioning (anchor) node or may have unknown positions and may be jointly positioned with the target UE. During joint positioning, each of the other UEs may similarly broadcast a common set of SRS that is received and measured by the base stations and other UEs for positioning. An angular measurement of the SRS broadcast by one or more UEs may be measured and used to resolve mirror symmetry in positioning solutions.

Abstract: Some aspects described herein relate to transmitting, to a receiving user equipment (UE), an indication of a fixed size transport block size (TBS) used for a sidelink transmission, and transmitting, to the receiving UE and based at least in part on the fixed size TBS, the sidelink transmission over sidelink resources. Other aspects relate to the receiving UE receiving the indication and the sidelink transmission. Additional aspects relate to a base station for configuring the sidelink resources for fixed size TBS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine an estimated total amount of resources for one or more retransmissions of communications among the base station, a controller, and a device, the one or more retransmissions associated with one or more transmissions between at least two of the base station, the controller, or the device; and transmit, to at least one of the controller or the device, an indication of an allocation of resources based at least in part on the estimated total amount of resources for the one or more retransmissions. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for a wireless communication are described. A base station may control multiple parameters for sidelink communication configurations to be used by a user equipment (UE) for sidelink communications. The base station may determine the multiple parameters for sidelink communication configurations and configure multiple UEs for sidelink communication based on the determination. The multiple parameters may include a modulation and coding scheme, a redundancy version, a demodulation reference signal pattern or port, a transmit power control, a sidelink hybrid automatic repeat request (HARQ) indicator, a cast type, a HARQ process number, a receiver UE identifier, or any combination thereof. The indication may be included in downlink control information.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that the first UE is to receive a sidelink transmission from a second UE, the sidelink transmission comprising a sidelink control channel and a sidelink data channel. The first UE may receive, based at least in part on a first resource configuration for a sidelink feedback channel failing to satisfy a resource threshold associated with transmitting a feedback message, an indication of a second resource configuration from the second UE, the second resource configuration for transmitting the feedback message to the second UE for the sidelink transmission, the second resource configuration satisfying the resource threshold. The first UE may receive the sidelink transmission from the second UE. The first UE may transmit, to the second UE, the feedback message using the second resource configuration.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may belong to a group of UEs and may identify a channel sensing schedule for the group of UEs. The channel sensing schedule may include sensing windows and resource reservation windows corresponding to each UE of the group of UEs. The channel sensing schedule may establish a pattern for the sensing windows and resource reservation windows such that the UEs may take turns performing sensing and resource selection. During a sensing window associated with the UE, the UE may sense a set of resources of a sidelink communication link to identify candidate resources. The UE may transmit, to the other UEs of the group, a message indicating results of the sensing, such as an indication of resource reservations, candidate resources, or the like. The other UEs may identify and select candidate resources based on the message.
