Embodiment Construction

[0183] figure 1 Shown is a device 100 for sending a message (eg user plane data packet) 101 over a wireless communication system. The device 100 may in particular be a UE, for example a UE used in a vehicle, or a vehicle. To send the message 101 , the device 100 is configured to select one of the assisted mode 102 , the ad-hoc mode 103 , and the combined assisted and ad-hoc mode 104 . The above-mentioned selection may also include specification of one or more resources related to the selected mode, such as a predefined resource block for the assisted mode. After the selection has been performed, the message 101 is sent via the selected mode. This selection may eg be an initial selection, ie the mode is selected for the first time (eg at start-up). The selection may also include, for example, changing the currently used mode to the newly selected mode.

[0184] In other words, the device 100 enables an initial selection of a communication mode (which may include session / co...

Abstract

The present invention relates to the field of mobile communication, in particular vehicle-to-anything (V2X) communication, and provides a device (100) for transmitting a message (101) over a wirelesscommunication system, in particular a UE, wherein the device (100) is configured to select one of an assisted mode (102), an ad-hoc mode (103), or a combined assisted and ad-hoc mode (104); and transmit the message (101) over the selected mode. To support bi-directional transmission, the present invention also provides a device (1500) for receiving a message (1501) over a wireless communication system, in particular a UE, wherein the device (1500) is configured to select one of an assisted mode (1502), an ad-hoc mode (1503), or a combined assisted and ad-hoc mode (1504); receive the message (1501) over the selected mode. The present invention also provides a management device (1700), in particular a network device, for supporting a device for transmitting and / or receiving a message over awireless communication system.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to vehicle-to-anything (V2X) communication. More specifically, the present invention provides devices that can select an assisted mode, an ad-hoc mode, or a combined assisted and ad-hoc mode for sending and / or receiving messages, particularly during V2X communication. Background technique [0002] With the advent of autonomous driving features, and especially with the widespread adoption of vehicles capable of supporting higher levels of automation, the need for synchronization and coordination between vehicles becomes increasingly necessary. Vehicles communicate directly with each other to extend their sensing range beyond the capabilities and range provided by their integrated sensors. Typical examples of V2X services are cooperative lane changing, cooperative collision avoidance, and platooning, where networked autonomous vehicles participate and the performance requi...
