2 results about "Vehicle to everything" patented technology

A communication method and apparatus are applied to the field of vehicle to everything (V2X) or the like. The method includes: determining a first slot in a resource selection window, where the first slot is used to transmit a first reference signal, the resource selection window includes at least one slot, and the first slot is an unreserved slot, or the first slot is a slot reserved for transmitting a second reference signal; and sending first indication information, where the first indication information indicates the first slot. According to the foregoing method, a flexible method for determining a reference signal resource is implemented through sensing and resource selection, and the first slot determined in the resource selection window is an unreserved slot or a slot reserved for transmitting the second reference signal. Therefore, a same slot is not shared with a resource for data transmission, so that sending of the first reference signal in the first slot does not interfere with data transmission in the first slot, thereby ensuring reliability of data transmission.

Embodiments herein relate e.g. to a method performed by a vehicle to everything, V2X, wireless device (10) for handling a service in a wireless communication network. The V2X wireless device (10) receives from a network node (13) an announcement message comprising data relating to a group of wireless devices; and transmits to the network node a response to the received announcement message for registering to the group of wireless devices .
