Problems solved by technology

In the vehicle-to-everything (V2X) scenario, multiple V2X services are provided under channels that vary greatly, so the required quality of service (QoS, quality of service) cannot be achieved
Mobile communication systems cannot provide acceptable performance due to varying scenarios of high / low mobility, high / low Doppler, small / large delay spread, and various business requirements for latency and reliability requirements

Embodiment Construction

[0091] In the following Detailed Description, reference is made to the accompanying drawings, which form a part hereof, and which show by way of illustration certain aspects in which the disclosure may be practiced. It is to be understood that other aspects may be utilized and structural or logical changes may be made without departing from the scope of the present disclosure. Accordingly, the following detailed description should not be viewed in a limiting sense, and the scope of the present disclosure is defined by the appended claims.

[0092] It should be understood that explanations made in connection with a described method may also apply to a corresponding device or system configured to perform the method, and vice versa. For example, if certain method steps are described, a corresponding device may include units for performing the described method steps, even if such units are not explicitly described or shown in the figures. Furthermore, it should be understood that...

Abstract

The disclosure relates to a mobile communication device (1000), comprising: a receiver (1001), configured to receive a radio signal (1002) over a radio channel, the radio signal (1002) comprising a predetermined pilot preamble; and a processor (1003), configured to determine mobility information (1004), in particular a Doppler and / or a Delay Spread, based on the pilot preamble, wherein the processor (1003) is further configured to signal the mobility information (1004) to a second communication device (1100). The disclosure further relates to a base station (1100), comprising: a receiver (1101), configured to receive mobility information (1004), in particular a Doppler and / or a Delay Spread, signaled by a mobile communication device; and a processor (1103), configured to select a numerology (301, 302, 303, 304) based on the mobility information (1004) and to generate a radio signal (1104) for transmission to the communication device (1000) based on the numerology (301, 302, 303, 304).

Description

technical field [0001] The present disclosure relates to a communication technology based on an adaptive parameter set, and in particular to a mobile communication device that sends mobility information to a second communication device through a signal, and selects a parameter set suitable for transmission of a wireless signal based on the signaled mobility information base station. In particular, the present invention relates to a system and method for supporting an adaptive parameter set in a 5G enhanced vehicle-to-everything (5G-eV2x) scenario. Background technique [0002] In the 5G mobile communication system, multiple slices and services can be provided. In a vehicle-to-everything (V2X) scenario, multiple V2X services are provided on channels with large variations, so the required quality of service (QoS, quality of service) cannot be achieved. Due to varying scenarios of high / low mobility, high / low Doppler, small / large delay spread, and various business requirements...
