  • Publication number: 20220015068
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, techniques for improving semi-persistent scheduling performance, including in the context of cellular vehicle-to everything (CV2X) communications, are provided. For example, a method of wireless communication performed by a user equipment can include determining a first periodicity for transmitting safety messages, determining a second periodicity for transmitting the safety messages, wherein the second periodicity is different than the first periodicity, determining, based on a probabilistic determination process, whether to continue with the first periodicity or switch to the second periodicity, generating, based on the determination to continue with the first periodicity or switch to the second periodicity, the safety messages at the first periodicity or the second periodicity, and transmitting the safety messages at a same periodicity at which the safety messages were generated.

  • Publication number: 20210359782
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a control channel message encoded according to a first format that is associated with a different set of shared data channel parameters than a second format supported by the UE. The second format is a legacy format relative to the first format. The UE may further determine that the control channel message is encoded according to the first format based at least in part on comparing one or more bit values, of the control channel message, in bit positions corresponding to a set of bits defined by the second format, and one or more expected bit values defined by the first format. The UE may select one or more resources for transmission based at least in part on information included in the control channel message. Numerous other aspects are provided.

  • Patent number: 11140641
    Abstract: Aspects directed towards synchronizing out of coverage (OOC) vehicle-to-everything (V2X) communications are disclosed. In one example, a scheduled entity detects a loss of a synchronization signal associated with a V2X communication by detecting when a timing uncertainty value or error value is greater than a threshold value. Packet timing information is then received in response to the loss of the synchronization signal from at least one user equipment (UE) synchronized with the synchronization signal. The scheduled entity then maintains the V2X communication by performing a timing adjustment based on the packet timing information.
