Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may utilize priority levels associated with packets or transmissions to determine whether to transmit feedback for a received transmission. The UE may compare priority levels between a transmission subject to a feedback condition and a transmission scheduled to be received when the feedback is scheduled to be transmitted to determine whether to send the feedback. The UE may communicate with the transmitting device according to the comparison and the determining. The UE may determine signal conditions causing a NAK and determine to send the NAK based on the signal conditions.

Abstract: Improved communications, including indication of channel occupancy time-structure information (COT-SI) for NR-U sidelink (NR-U SL) operations is disclosed. A UE may establish a current channel occupancy time (COT) on a shared communication spectrum for UE transmissions in response to a successful listen before talk (LBT) procedure. The UE may then generates a COT structure information (COT-SI) message including at least a remaining duration of the current COT and a set of time and frequency resources of the current COT. The COT-SI message may be transmitted by the UE to one or more neighboring UEs via sidelink transmission. Once the COT-SI message is sent, the UE transmits the UE transmission within the set of time and frequency resource of the current COT.

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: Methods, systems, and devices for wireless communications are described. A first device may identify that a first set of transmission resources in a transmission time interval (TTI) has a higher priority at a second device than a second set of transmission resources in the TTI. The first device may identify that a message is to be transmitted from the first device to the second device via the TTI and process the message into a bit sequence based on the identification of the second set of transmission resources in the TTI, where the processing increases a likelihood that systematic bits of the message are received at the second device despite presence of the second set of transmission resources in the TTI. The first device may transmit the bit sequence to the second device via the TTI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may initiate a radio resource control (RRC) layer signaling procedure between the UE and a target UE, include an upper layer signaling message in an RRC message based in part on the RRC layer signaling procedure, and transmit the RRC message including the upper layer signaling message to the target UE. Alternatively, upper layer signaling messages may be transmitted separately before or after the RRC layer signaling procedure.

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 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: 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, and devices for wireless communication are described. A 5G device may decode a control channel transmission of a safety message in a vehicle-to-everything system during a first portion of a time period. The 5G device may identify, based at least in part on the decoding, a pool of resource blocks (RBs) that are available for the time period. The 5G device may select a subset of RBs from the available pool of RBs for a transmission during a second portion of the time period.
