Abstract: Methods, systems, and devices for wireless communications are described that may enable a user equipment (UE) to transmit sidelink data within an interference avoidance resource scheduling scheme. For example, a UE may determine to segment a data packet for transmission in a vehicle-to-everything (V2x) system (e.g., to ensure that each segment fits within one transmission time interval (TTI)). In some cases, a UE may identify a data packet for transmission, may determine that the size of the data packet exceeds a threshold size, may segment the data packet to ensure each segment fits within one TTI, and may transmit the data packet segments (e.g., to additional UEs), where said transmissions may be discontinuous. In some examples, a UE may determine to segment the data packet and then encode the data packet. Additionally or alternatively, the UE may determine to encode the data packet and then segment the data packet.

Abstract: Various aspects of the disclosure relate to the selection and use of modulation and coding scheme (MCS) values. For example, a first MCS table may be used for a first condition and a second MCS table used for a second condition. The disclosure relates in some aspects to inter-device signaling that indicates which MCS table is to be used for communication between the devices.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive a sidelink message via a sidelink transmission resource of a shared sidelink resource pool that is shared between a communications according to a first radio access technology (RAT) and communications according to a second RAT. The UE may map sidelink transmission resource occasions of the shared resource pool to a physical sidelink feedback channel (PSFCH) occasion and map subchannels of the sidelink transmission occasions to respective resources of the PSFCH occasion. The UE may transmit a sidelink feedback message corresponding to the sidelink message using a resource of the PSFCH occasion corresponding to a subchannel carrying sidelink control information of the sidelink message.

Abstract: In some aspects, a method of wireless communication includes performing a full reference signal receive power (RSRP) sweep for a first slot to determine a first resource exclusion RSRP threshold, and performing a resource reevaluation for a second slot based on the first resource exclusion RSRP threshold from the first slot. In some aspects, a method of wireless communication may include performing a full RSRP sweep for a first slot to determine a first resource exclusion RSRP threshold and performing the full RSRP sweep for a second slot that is a number of slots following the first slot to determine a second resource exclusion RSRP threshold. For each slot between the first slot and the second slot, the resource reevaluation may be performed based on the first resource exclusion RSRP threshold determined for the first slot.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a second user equipment, an indication of a time buffer threshold associated with providing sidelink hybrid automatic repeat request feedback on a physical sidelink feedback channel. The UE may receive, from the second user equipment, an indication of an agreement to use the time buffer threshold. The UE may transmit, to the second user equipment and based at least in part on the indication of the agreement, sidelink hybrid automatic repeat request feedback for a sidelink communication received from the second user equipment, the sidelink hybrid automatic repeat request feedback being transmitted on the physical sidelink feedback channel based at least in part on the time buffer threshold.

Abstract: Disclosed is a method for wireless communication. The method comprises: determining a first set of slots within a sidelink resource pool, determining a set of candidate single-slot resources, each candidate single-slot resource associated with a slot of the first set of slots, determining a second set of slots within the sidelink resource pool based on the first set of slots, wherein the first set of slots and the second set of slots do not overlap, monitoring for one or more transmissions comprising control information in each slot of the second set of slots, wherein the monitoring comprises using a receive beam, selectively excluding, based on the control information, one or more resources from the set of candidate single-slot resources, and transmitting a sidelink transmission in one or more remaining resources of the set of candidate single-slot resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a first quantity of physical sidelink feedback channel (PSFCH) transmissions to be transmitted in a slot fails to satisfy a condition that is based at least in part on a maximum quantity of PSFCH transmissions the UE can concurrently detect. The UE may identify, among the PSFCH transmissions to be transmitted in the slot, a subset of the PSFCH transmissions to be detected. For example, the subset of the PSFCH transmissions to be detected may include a second quantity of the PSFCH transmissions that satisfies the condition. Accordingly, the UE may monitor, during the slot, a PSFCH for the subset of the PSFCH transmissions. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more sidelink communications on a sidelink between the UE and another UE. The UE may transmit one or more hybrid automatic repeat request (HARQ) feedback communications, associated with the one or more sidelink communications, on the sidelink and in a HARQ feedback resource included in a multi-slot feedback reporting period. The HARQ feedback resource may include a set of negative acknowledgement (NACK) resources or the set of NACK resources and a set of acknowledgement (ACK) resources. Numerous other aspects are provided.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from another UE, a coordination message that includes resource information (e.g., a preference status) for communication resources. The UE receiving the coordination message may determine a status of one or more resources based on the resource information, an intended recipient of the coordination message (e.g., based on a destination identifier of the coordination message), or a communication connection associated with the one or more resources. The status may indicate that a respective resource of the one or more resources is available, reserved, preferred, or non-preferred, or some combination thereof. In some examples, the one or more resources may be for a sidelink connection or a unicast connection. The receiving UE may utilize the determined status to select one or more resources for a sidelink transmission.
