Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) sense sidelink transmissions to determine a set of resources that may be reserved by one or more other UEs. The set of resources may include a first subset of resources associated with a first radio access technology (RAT) and a second subset of resources associated with a second, different RAT. The first UE may transmit a message to a second UE indicating resource information for transmissions by the second UE, and the resource information may indicate that the first subset of resources is associated with the first RAT and that the second subset of resources is associated with the second RAT. Additionally, or alternatively, the first UE may transmit an indication of collisions between resources reserved for transmissions associated with the first RAT and resources reserved for transmissions associated with the second RAT.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving user equipment (UE) may broadcast messages containing inter-UE cooperation (IUC) information using multiple beams. The IUC information transmitted on each beam may be different for each beam of the receiving UE. For example, each IUC information may contain different preferred resources or non-preferred resources for the receiving UE to receive a transmission from a transmitting UE. The transmitting UE may receive a message containing IUC information from one of the beams of the receiving UE and transmit a signal using resources based on the IUC information contained in the received message. In some examples, the transmitting UE may transmit a channel busy ratio (CBR) request to a receiving UE. The CBR request may specify a transmission configuration indicator (TCI) state, spatial relation, spatial domain filter, or beam according to which the receiving UE is to measure the CBR.

Abstract: Methods, systems, and devices for wireless communications are described. An example method for wireless communication at a first user equipment (UE) may include receiving at least a first sidelink transmission from a second UE, wherein at least a second sidelink transmission from a third UE is scheduled contemporaneously with at least the first sidelink transmission from the second UE. The method may also include transmitting an indication in a transmission occasion to at least one of the second UE or the third UE based at least in part on a prioritization of information for the transmission occasion, wherein the indication indicates that at least the first sidelink transmission from the second UE is scheduled contemporaneously with at least the second sidelink transmission from at least the third UE.

Abstract: Certain aspects of the present disclosure provide techniques for flexible resource reservations in sidelink communications. An example method that may be executed by a first user equipment (UE) includes determining, for sidelink communications with a second UE, one or more first resource reservations and one or more second resource reservations. The second resource reservations may have a different frequency resource allocation than the first resource reservations. The method also includes transmitting, to the second UE, control information having an indication of the first resource reservations and the second resource reservations. The method further includes communicating with the second UE based on the first resource reservations and the second resource reservations.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support multiple-transmission and reception point (multi-TRP) based positioning. In some aspects, a method includes transmitting, by a first user equipment (UE) including a first set of transmission and reception points (TRPs), a first request for a first sidelink (SL) positioning session. The first request indicates a multi-TRP positioning session is enabled. The method also includes receiving, from a second UE including a second set of TRPs, a first response based on the first request. The first response indicates a number of TRPs of the second set of TRPs available for the first SL positioning session. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A device (such as a first user equipment (UE)) may communicate control signaling indicating a resource allocation for a sidelink channel. The first UE may receive, from a second UE, a first resource map. The first resource map may indicate a first sidelink transmission scheduled within a first time and frequency resource of the resource allocation, a first priority level of the first resource map, and a parameter threshold used to generate the first resource map. In some cases, the first UE may communicate a second sidelink transmission within the resource allocation for the sidelink channel based on the first resource map.

Abstract: Methods, systems, and devices for encoding and decoding are described. To encode a vector, an encoder allocates information bits of the vector to channel instances of a channel that are separated into groups. The groups may vary in size and allocation of the information bits is based on a base sequence of a given length. During decoding, a decoder assigns different bit types to channels instances by dividing a codeword into a plurality of groups and assigning bit types to channel instances of the plurality of groups using the base sequence.

Abstract: A method of wireless communication performed by a sensing user equipment (UE) includes identifying available resources during a sensing window. The method also includes receiving a request to share the available resources with a transmitter UE. The method further includes determining the sensing UE satisfies a sharing condition. The method still further includes sharing the available resources with the transmitter UE based on satisfying the sharing condition.
