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: 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first transmission, wherein the first transmission includes information identifying a window, and wherein the UE is to transmit at least part of a second transmission in the window; and transmit at least part of the second transmission in the window. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide synchronization techniques for user equipment (UEs) that may be otherwise unable to support sidelink communication a synchronized UE and may have also lost global navigation satellite system (GNSS) and/or Evolved Node Base Stations (eNBs) as a synchronization source. In such instance, the unsynchronized UE may utilize reference signals (RS) from the data packets received from other UEs to track the timing and perform autonomous timing adjustments based thereon for synchronized packet transmission or reception.

Abstract: An aspect of the present disclosure includes methods, systems, and computer-readable media for transmitting a first message including sidelink information and location information of a peer UE, receiving a second message including radio resource control information, transmitting a buffer status report, receiving a grant for one or more resources in response to the buffer status report after a successful peer UE search, and transmitting a vehicle-to-vehicle message to the peer UE via the one or more resources.

Abstract: Aspects of the disclosure relate to a method of operating a scheduled entity for wireless communication. In some aspects, the scheduled entity determines to modify a first quality of service (QoS) level for a data transmission from the first device to a second device, wherein the first device is configured to communicate with the second device through a direct wireless communication link, and wherein the first QoS level is requested by an application of the first device. The scheduled entity modifies the first QoS level to a second QoS level, wherein the direct wireless communication link is able to support the second QoS level and is unable to support the first QoS level. The scheduled entity transmits the data transmission based on the second QoS level.

Abstract: Various aspects related to frequency biasing to compensate for frequency variations caused by Doppler shift in V2V communication systems are described. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus, e.g., a UE, may be configured to determine a velocity of the apparatus, and determine a frequency biasing adjustment based on the determined velocity of the apparatus. The apparatus may be further configured to communicate with UE based on an adjusted carrier frequency determined based on a carrier frequency and the determined frequency biasing adjustment. In some configurations, a driving environment of the apparatus maybe considered, and the frequency biasing adjustment is determined further based on the determined driving environment.
