Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of resource candidates in a sidelink communication system based at least in part on a set of resource assignments for a group of other UEs in the sidelink communication system. The UE may transmit a first part of a physical sidelink control channel (PSCCH) transmission. The UE may transmit a second part of the PSCCH transmission related to the first part of the PSCCH transmission to indicate a resource candidate, of the set of resource candidates, for a transmission associated with medium access control (MAC) protocol data units (PDUs) of a particular packet. 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 determine a plurality of ratios of free resources in a historical time window using respective control exclusion parameters corresponding to the plurality of ratios of free resources. The UE may determine a particular control exclusion parameter based at least in part on a ratio of free resources, of the plurality of ratios of free resources, satisfying a threshold. The UE may select a resource for a future transmission based at least in part on the particular control exclusion parameter. The UE may reserve the selected resource. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may encapsulate, into a link layer sidelink management message, upper layer signaling for managing a direct communication connection with a second UE. The first UE may transmit, to the second UE, the link layer sidelink management message including the upper layer signaling. The second UE may selectively transmit, to the first UE, a link layer sidelink response message based at least in part on a content of the upper layer signaling in the link layer sidelink management message. 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 a sidelink communication on a sidelink between the UE and another UE. The UE may transmit, on the sidelink, one or more feedback communications associated with the sidelink communication in a reporting period having a configurable periodicity and/or being configured to occupy an entire bandwidth of a resource pool configured for the sidelink. Numerous other aspects are provided.

Abstract: Disclosed are techniques for using ranging signals to determine a position of a pedestrian user equipment (P-UE). In an aspect, a UE receives a plurality of ranging signals transmitted by one or more UEs, measures one or more properties of each of the plurality of ranging signals, and calculates an estimate of the position of the P-UE based on the one or more properties of each of the plurality of ranging signals. In an aspect, the P-UE transmits a plurality of ranging signals, receives a first message and a second message from first and second vehicle UEs (V-UEs), the first and second messages including first and second estimated positions of the P-UE and associated first and second confidences, and calculates an estimate of the position of the P-UE based on the first estimated position, the first confidence, the second estimated position, the second confidence, or a combination thereof.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication include re-coding a first coded packet into a second coded packet, wherein the second coded packet includes less coded bits and has a higher modulation order than the first packet, generating one or more redundant versions of the second packet, and transmitting the second packet and the one or more redundant versions of the second packet at different times to a receiving user equipment.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication by a user equipment (UE) includes transmitting a packet on a first resource, determining one or more repetition resources on which to send one or more redundancy versions of the packet, wherein the one or more repetition resources are at a time subsequent to the first resource, transmitting repetition resource information identifying the one or more repetition resources to one or more neighboring UEs, and transmitting the one or more redundancy versions of the packet on respective ones of the one or more repetition resources.

Abstract: The present disclosure relates to methods and devices for group communication which may include a first UE and a set of UEs. In one aspect, the first UE may receive from each UE of the set of UEs a PDU including a header that includes a QoS level for the UE. The first UE can also determine a supported QoS level for the first UE. In another aspect, the first UE can set a transmission QoS level for the first UE to be a lowest QoS level of the determined supported QoS level and the QoS level from each UE of the set of UEs. In a further aspect, the first UE can transmit by multicast to the set of UEs a PDU based on the set transmission QoS level.

Abstract: Aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a peer-to-peer (P2P) communication is to be relayed based at least in part on a location of the UE and a range requirement associated with the P2P communication; and transmit the P2P communication, wherein the P2P communication includes an indication of whether the P2P communication is to be relayed. In some aspects, a UE may receive the P2P communication; determine whether to relay the P2P communication based at least in part on the indication and at least one of: a location of the UE, or a UE identifier, included in the P2P communication, that identifies the UE and is associated with a request for the UE to relay the P2P communication; and selectively relay the P2P communication based at least in part on determining whether to relay the P2P communication.
