Problems solved by technology

[0009] On the one hand, according to the current discussion, the delay requirement of most V2V / V2I / V2P services is 100 milliseconds or even 20 milliseconds, and the resource allocation method of the existing uplink cellular and PC5 interface may not be able to meet the delay requirement. Especially for Scenario 3, the existing resource allocation method cannot meet the delay requirement
[0010] On the other hand, when using the PC5 interface for communication, due to the influence of half-duplex, if the sender and receiver use the same frequency band for communication, if the two send messages at the same subframe position, the two cannot receive each other's messages at the same time. message, resulting in missing messages from other terminals. Even if the retransmission scheme is adopted, this situation cannot be completely avoided. If the number of retransmissions is too large, it will bring excessive delay, which exceeds the delay requirement.

Embodiment 1

[0132] Such as figure 2 As shown, this embodiment provides a resource application method, the method includes:

[0133] Step S110: sending low-latency service information to the network control unit;

[0134] Step S120: Receive resource allocation information, the resource allocation information is formed by resource allocation by the network control unit based on the low-latency service information.

[0135] The execution subject that executes the resource application method described in this embodiment may be various user equipments, for example, various vehicle-mounted equipments.

[0136] In this embodiment, the low-latency service information may include various low-latency service-related information, which may be used to provide the network control unit with a basis for the latency of resource allocation. The low-delay service information may indicate the low-delay service, and the network control unit determines the delay requirement of the low-delay service; or the...

Embodiment 2

[0178] Such as image 3 As shown, this embodiment provides a resource allocation method, the method includes:

[0179] Step S210: receiving the low-latency service information sent by the user equipment;

[0180] Step S220: Perform resource allocation according to the low-latency service information;

[0181] Step S230: Based on the resource allocation result, send resource allocation information to the user equipment.

[0182] The method described in this embodiment is a method applied to a network control unit. In this embodiment, the network control unit may be a base station, a roadside unit, or a relay node, and other communication nodes capable of resource scheduling or allocation. . In this embodiment, the low-latency service may include the aforementioned V2X service.

[0183] When the received network control node responds to the resource request and allocates resources in this embodiment, it will perform resource allocation according to the low-latency service in...

Embodiment 3

[0225] Such as Figure 4 As shown, this embodiment provides a user equipment UE, and the user equipment includes:

[0226] The first sending unit 110 is configured to send low-latency service information to the network control unit;

[0227] The first receiving unit 120 is configured to receive resource allocation information, where the resource allocation information is formed by resource allocation performed by the network control unit based on the low-latency service information.

[0228] This embodiment provides a user equipment, and the user equipment may be various terminal equipment, for example, a vehicle-mounted terminal equipment.

[0229] Both the first sending unit 110 and the first receiving unit 120 correspond to communication interfaces. In this embodiment, the communication interface is usually a wireless interface. For example, mobile antennas for vehicle equipment, etc.

[0230] In this embodiment, when the user equipment requests resources, the first sen...
