Abstract: Methods, systems, and devices for wireless communications are described herein. A transmitting device (e.g., a user equipment (UE), a network entity) may generate a low-density parity-check code according to a base graph, which may be defined by variable nodes and check nodes. The base graph may support second degree variable nodes in the information nodes of the base graph and a larger quantity of second degree nodes associated with higher significance bits than with lower significance bits. Higher significance levels (e.g., bits) may correspond to higher channel reliabilities. The base graph may be a universal base graph or may include additional rules specific to probabilistic shaping. In some examples, an interleaver may be defined to map the base graph to symbols. In some cases, the UE may report its capability to support one or more interleavers, or the network entity may configure the UE with an interleaver.

Abstract: Methods, systems, and devices for wireless communications are described. User equipment (UE) may communicate sidelink coordination messages to indicate potential interference and select sidelink resources. For example, a first UE may transmit a sidelink coordination message to a second UE that includes a set of identifiers associated with a set of UEs. The second UE may select a first set of sidelink resources for a first sidelink communication with the first UE based on a reference signal received power (RSRP) of the sidelink coordination message and a reservation of a second set of sidelink resources for a second sidelink communication between the first UE and third UE of the set of UEs. For example, the second UE may determine the reservation, select the first set to be non-overlapping a time domain with the second set based on the RSRP, and perform the second sidelink communication with the first UE.

Abstract: A user equipment (UE) can transmit first radio access information indicating a first ratio of first sidelink devices configured to use a first radio access technology (RAT) to second sidelink devices configured to use a second RAT. The UE can receive second radio access information from one or more sidelink devices of at least one of the first sidelink devices or the second sidelink devices. Each second radio access information indicates a respective second ratio of the first sidelink devices configured to use the first RAT to the second sidelink devices configured to use the second RAT. The UE can select a resource pool frame structure based on the first ratio and each of the respective second ratios, and the resource pool frame structure is configured to partition a resource pool between the first RAT and the second RAT for sidelink communication in a sidelink network.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) determines a comb offset for a sidelink positioning reference signal (SL-PRS), transmits an indication of the comb offset to a second UE, and transmits the SL-PRS in accordance with the comb offset. The second UE receives the SL-PRS in accordance with the comb offset.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may identify a set of time and frequency resources reserved by one or more second UEs for one of sidelink transmissions by the one or more second UEs to the first UE or to one or more third UEs (e.g., type A), or sidelink transmissions by the first UE to one or more third UEs (e.g., type B), and may select a first indicator and a second indicator for the reservation. The first indicator of a time resource and the second indicator of a frequency resource may be associated with the identified set of time and frequency resources for the reservation. The UE may transmit a coordination message that includes the first indicator and the second indicator, and includes an indication that the message is associated with type A or type B reservations.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless communication device engages in a sidelink positioning session with at least one other wireless communication device, and transmits, during the sidelink positioning session, one or more sidelink positioning reference signal (SL-PRS) resources on a subset of resources of a shared sidelink resource pool, wherein the subset of resources is allocated within the shared sidelink resource pool for the sidelink positioning session based on one or more criteria.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more signals associated with a sidelink channel to perform sensing of the sidelink channel. The UE may transmit a control signal associated with a first radio access technology (RAT) to reserve a set of resources associated with a resource pool for the sidelink channel based at least in part on the sensing of the sidelink channel, wherein at least one of the set of resources or the resource pool is associated with a second RAT. The UE may transmit, using one or more resources from the set of resources, a first sidelink message, wherein the first sidelink message is associated with the second RAT. Numerous other aspects are described.

Abstract: A first user equipment (UE) receives sidelink resource reservation information over sidelink from one or more UEs. The first UE transmits inter-UE coordination information in a sidelink transmission based on a probability threshold being met. A wireless device may receive one or more of a status of a UE, a capability of the UE, or a report. The wireless device may configure the UE with a probability threshold for transmission of inter-UE coordination information in a sidelink transmission.

Abstract: A first UE and at least one second UE are disclosed. The first UE may identify one or more resources that are suitable for a subsequent transmission from at least one second UE. The first UE may transmit to the at least one second UE, an inter-UE coordination message and at least one data transmission. The inter-UE coordination message may be transmitted at a same time as the at least one data transmission. The inter-UE coordination message may include an indication of the one or more resources that are suitable for the subsequent transmission from the at least one second UE. In one configuration, the inter-UE coordination message may be piggybacked with the at least one data transmission. The at least one second UE may transmit the subsequent transmission via the one or more resources, or may reselect the one or more resources based on the inter-UE coordination message.

Abstract: Certain aspects of the present disclosure provide techniques for device-to-device sidelink collision indication (s) based on distance-based conditions. An example method performed by a user equipment (UE) generally includes receiving resource reservation information indicating reservations of resources by at least a second UE and a third UE; and transmitting a collision indication to at least one of the second UE or the third UE when the resource reservation information indicates colliding transmissions and at least one distance-based condition is met.
