    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, base stations and user equipments may use a hybrid operation mode to allocate resources in a cellular vehicle-to-everything communication system. For example, a user equipment (e.g., a vehicle) in the system may receive, from a base station, an indication that the user equipment belongs to at least one group of user equipments for group-level resource allocation, receive, from the base station, an allocation of resources including a pool of resources assigned to the at least one group of user equipments, and reserve a subset of resources of the pool of resources for communication to at least one other user equipment. This communication may be an example of a vehicle-to-everything communication over a sidelink communication channel.

    Abstract: Described are methods for interference detection and management in a millimeter wave communications system. A V2X communications system may support interference management procedures that comprise scheduling a system wide training interval in a transmission timeslot, suspending traffic transmissions on a link in the communications system during the training interval to perform training on the link, and resuming traffic transmissions on the link if interference is not detected during the training interval. Interference management procedures may also include receiving at a node, unique parameters transmitted from another node in a communication system during a discovery stage, determining whether interference will occur at the node based on the received unique parameters, and suspending transmissions to and from the node if it is determined interference will occur at the node..

    Abstract: A user equipment (UE) may communicate with one or more other UEs using multiple transmissions in a device-to-device (D2D) communications deployment. A number of UEs may be configured with D2D resources, and a transmitting UE may identify available D2D resources from the configured resources. The transmitting UE may identify a resource for a first transmission of a D2D transmission from the available D2D resources, and may identify a second resource for a second transmission of the D2D transmission. The second transmission may be a blind HARQ transmission that may be transmitted to enhance the likelihood that one or more receiving UEs successfully receive the transmission. In some examples, the second resource may be identified based on other available resources within an predetermined time window around the first transmission.

The UE may be further configured to select, in response to identifying that the recent sensing history information is unavailable, a resource selection procedure based on configuration information obtained from a network entity. In various configurations, the UE may select a resource for a V2V transmission based on the resource selection procedure selected based on the configuration information.

    Abstract: Improvements may be made for the Channel Busy Ratio, CBR, based congestion control considering different technologies, types of radio resources, and priorities of different packets. The apparatus may be a User Equipment, UE. The UE determines an energy-based channel busy ratio (CBR) based on a number of probes on a set of radio resources having respective energy levels greater than an energy threshold. The UE performs congestion control based on the energy-based CBR by adjusting at least one transmission parameter of one or more transmission parameters or transmission power of the UE based on the energy-based CBR.The adjusting may be carried out taking into account a usage limit, or CBR limit. In addition, the UE may detect that a second technology different from a first technology is also using the channel, and in addition consider a decode-based CBR for the purpose.
