Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a selection window after an arrival of a packet. The selection window may be selected based at least in part on a delay budget associated with the packet. The UE may determine, based at least in part on the selection window, a control exclusion zone value. The UE may perform, based at least in part on the control exclusion zone value, a resource selection associated with determining available resources for transmitting a set of transmissions associated with the 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 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: Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) establishes a radio resource control (RRC) connection for a communication session with a second UE, establishes a signaling radio bearer (SRB) for the communication session with the second UE on a first frequency band, sends, to the second UE over the SRB on the first frequency band, a first RRC message to establish a data radio bearer (DRB) for the communication session on a second frequency band, the first RRC message including one or more parameters for establishing the DRB on the second frequency band, and configures the DRB on the second frequency band based on the one or more parameters in the first RRC message and/or a device-to-device discovery procedure performed in the first frequency band.

Abstract: Aspects of the disclosure relate to mechanisms for code block segmentation in a wireless communication network (e.g., a sidelink network). In some examples, a wireless communication device may reserve resources across two or more slots on a carrier for transmission of a transport block. The wireless communication device may then select code block parameters for segmenting the transport block into a plurality of encoded code blocks such that each encoded code bock is fully contained within a single slot. In some examples, the code block parameters may include a number of encoded code blocks and a respective size of each of the encoded code blocks.

Abstract: Certain aspects of the present disclosure provide techniques for half-duplex handling with system-wide feedback resources. Embodiments include determining, for a first feedback resource corresponding to a first time period, that the wireless node has a scheduled feedback transmission and a scheduled feedback reception on shared frequency resources. Embodiments include selecting one of the scheduled feedback transmission or the scheduled feedback reception based on a rule. Embodiments include using the feedback resource to perform the selected one of the scheduled feedback transmission or the scheduled feedback reception.

Abstract: Aspects described herein relate to managing coexistence of multiple radio access technology (RAT) components in a device. Information related to an upcoming time period can be sent to a first radio access technology (RAT) component from a second RAT component. The first RAT component can select a resource to transmit a first RAT packet to minimize collision with the upcoming time period of the second RAT.

Abstract: Aspects described herein relate to transmitting a direct link synchronization signal for wireless communications. A user equipment (UE) may determine a synchronization signal priority level. The UE may determine a number of resources in a synchronization signal period on which to transmit a direct link synchronization signal block from the UE based on the synchronization signal priority level. The UE may transmit the direct link synchronization signal block on the number of resources.

Abstract: Methods, systems, computer-readable media, and apparatuses for vehicle emergency vehicle-to-anything (V2X) notification based on sensor fusion are presented. In some embodiments, a vehicle may receive an indication of an issue or impairment of the vehicle or an occupant of the vehicle, including the driver. Using information from sensors within the vehicle, an on-board processor may determine the nature of the impairment. Information about the nature of the impairment may then be transmitted, using V2X notification, to neighboring vehicles and/or an infrastructure entity (e.g., a base station, a roadside unit, a radio tower, and/or a central application server). The neighboring vehicles may then negotiate using V2X communication with the impaired vehicle and the other neighboring vehicles and/or be directed by the infrastructure entity to proceed using a negotiated course of action that accounts for the nature of the impairment in the impaired vehicle.

Abstract: Certain aspects of the present disclosure provide techniques for signaling frequency hopping information for data transmissions sent over a plurality of transmission time intervals. In some cases, a sequence may be selected and transmitted to indicate whether frequency hopping is used and/or additional information about how the frequency hopping will occur.

Abstract: Aspects of the disclosure relate to a distributed channel access mechanism using multiple access (MA) signatures for control transmissions. In one aspect, a transmitting device determines a MA signature for distinguishing a transmission of the transmitting device from another transmission of another transmitting device on a same frequency resource, transmits sidelink control information using the MA signature on a first set of frequency resources, the sidelink control information corresponding to first data information, transmits the first data information on the first set of frequency resources, and receives, from a receiving device, a response indicating whether reception of the first data information was successful. Other aspects, embodiments, and features are also claimed and described.
