Problems solved by technology
However, there are currently no 3GPP standards addressing MIMO in the sidelink
[0014] Regarding the selection of antennas for use in MIMO communication, most conventional solutions for massive MIMO require knowledge of the channel, which is a disadvantage for vehicular communication due to mobility
Other solutions for antenna selection / pairing for MIMO device-to-device (D2D) systems rely on multipath channel state information (not suitable for high-mobility environments), and the complexity of the above solutions varies with antenna and D2D grows in volume

Embodiment Construction
[0113] figure 1 A mobile device 100 including more than one antenna 101 according to an embodiment of the application is shown. The mobile device 100 is configured to communicate wirelessly, eg, with a network device 110 and / or another mobile device 100 (which may have the same capabilities as the device 100). The mobile device 100 may be, for example, a UE and / or provided at a vehicle. In the latter case, the mobile device 100 can perform wireless communication (V2V) with another mobile device 100 provided at another vehicle. Generally, the mobile device 100 can be used for V2X communication.
[0114] According to the present application, the mobile device 100 is configured to send the capability information 102 to the network device 110 and / or the aforementioned another mobile device 100 . The capability information 102 includes at least an indication 103 of the capability of the mobile device 100 to communicate using the plurality of antennas 101 , and at least one ante...

The present application respectively provides a mobile device and a network device for wireless communication, specifically V2X communication. Mobile devices include more than one antenna. The mobile device is used to send capability information to the network device and / or another mobile device. The capability information includes an indication of the capability of the mobile device to communicate using a plurality of antennas, and includes antenna characteristics of at least one of the plurality of antennas. The network device is configured to receive capability information from the mobile device and determine a set of antennas to be used by the mobile device to communicate with another mobile device based on the received capability information. The network device is then used to send information about the set of antennas to the mobile device. Alternatively, mobile devices may exchange capability and characteristic information with each other to allow for a distributed selection of the best set of antennas to use.
Description
technical field [0001] The present application relates respectively to mobile devices and network devices for wireless communication. Thus, the mobile device is used to communicate with another mobile device, specifically using multiple antennas, and the network device is used to select the multiple antennas used for such communication between the mobile devices. The mobile device and network device of the present application are particularly suitable for vehicle-to-everything (V2X) communication, such as vehicle-to-vehicle (V2V), vehicle-to-infrastructure, and / or vehicle-to-pedestrian communication . Background technique [0002] With the advent of autonomous driving capabilities, vehicles will be connected and vehicles will communicate to exchange sensor data and planned trajectories. Autonomous driving sets stringent performance requirements (latency, reliability, capacity) for 5G communication systems. For example, an end-to-end latency of less than 10 ms and a reliab...
