Abstract: A method for a network entity for controlling a communication between a first communication device and a second communication device including obtaining positions of communication devices and determining radiation boundary volumes in an environment of the communication devices based on the positions. Each radiation boundary volume includes a horizontal layer. A method including allocating the radiation boundary volume of radiation boundary volumes to the first communication device of communication devices to communicate with the second communication device of communication devices and transmitting information about the allocated radiation boundary volume to at least one of the first communication device and the second communication device.

Abstract: A method for a network entity for controlling a communication between a first communication device and a second communication device. The method includes receiving from the first communication device a space allocation non-compliance (SANC) message having information about a usage of a radiation boundary area by the second communication device, the radiation boundary area being assigned for usage by the first communication device. The method also includes determining an interference between communication signals of the first and second communication devices in the radiation boundary area and transmitting information about the determined interference to the second communication device.

Abstract: A method for a relaying system. The method for improving an awareness of the relaying system by user equipment includes encoding information about a relaying service in a vehicle-to-everything message and transmitting the vehicle-to-everything message to the user equipment to improve user equipment's awareness of the relaying system's relaying service.

Abstract: A method for a network entity. The method for controlling a communication between a first communication device and a second communication device includes obtaining positions of communication devices and determining radiation boundary areas in an environment of the communication devices. The method also includes allocating a radiation boundary area of the radiation boundary areas to the first communication device of the communication devices to communicate with the second communication device of the communication devices and transmitting information about the allocated radiation boundary area to the first communication device and/or the second communication device.

Abstract: A method for a relaying system for improving a handover list for user equipment connected to the relaying system which includes obtaining handover lists, obtaining a position of the relaying system, determining a handover list of the multiple handover lists based on the position of the relaying system, and transmitting the determined handover list to the user equipment.

Abstract: A method for user equipment connected to a cell for improving a handover list including obtaining information about communication devices in an environment and generating the handover list, transmitting the handover list to the cell and transmitting dynamic information about an own state to the cell, and receiving an improved handover list from the cell.

Abstract: A method for user equipment for improving a transmission efficiency on a radio channel including obtaining a predictive environmental model and predicting a channel dynamic of the radio channel based on the predictive environmental model, receiving a reference signal to measure a channel characteristic of the radio channel and calculating the channel dynamic of the radio channel based on the reference signal, and determining a deviation between the predicted channel dynamic and the calculated channel dynamic and adjusting a transmission parameter based on the deviation to improve the transmission efficiency on the radio channel.

Abstract: A method for user equipment to improve position information of one or more communication devices including obtaining map information about positions of the one or more communication devices, determining radio channel information about the one or more communication devices by analyzing a radio channel, and generating a node map having improved position information of the one or more communication devices using the map information and the radio channel information.

Abstract: A method for a communication device to adjust a processing gain of a radio communication with another communication device including transmitting a request for processing gain information to the other communication device, which allows the communication device to achieve a processing gain necessary for a service of the radio communication and receiving a processing gain response message including the processing gain information from the other communication device.
