Problems solved by technology

In Rel-15, evolved V2x (eV2x) has expanded to low-latency services. The current minimum value of T2 is 20, which means that the service delay standard that the current system can support is 20ms. For low-latency services, it may require The delay is 10ms or even 5ms, which requires reducing the value of T2, which may lead to a smaller interval from T1 to T2, resulting in fewer selectable resources, or even unable to select available resources

Embodiment Construction

[0065] In order to understand the characteristics and technical contents of the embodiments of the present application in more detail, the implementation of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present application.

[0066] In order to facilitate understanding of the technical solutions of the embodiments of the present application, Mode 3 and Mode 4 are respectively explained below.

[0067] Mode 3: if figure 1 As shown, the transmission resource of the vehicle terminal is allocated by the base station (such as the evolved base station (eNB, evolved NodeB) in LTE). Grant resource control message; then, the vehicle-mounted terminal sends data on the SL according to the resources allocated by the base station. In mode 3, the base station can allocate resources for a single trans...

Abstract

A method and a device for a terminal to select a resource, and a computer storage medium, said method comprising: a physical layer of a terminal performing resource monitoring in a monitoring window,and performing, in a selection window, resource selection on the basis of the monitoring result according to at least one T2 value, the time range corresponding to the selection window being [n+T1, n+T2], n being the current moment, T2 being greater than T1; and the physical layer of the terminal sending a resource selection result to an MAC layer.

Description

technical field [0001] The present application relates to the Internet of Vehicles technology in the field of mobile communication, and in particular to a method and device for selecting resources by a terminal, and a computer storage medium. Background technique [0002] The Internet of Vehicles system adopts the long-term evolution (LTE, Long Term Evolution)-device-to-device (D2D, Device to Device) sidelink (SL, Sidelink) transmission technology, and the communication data in the traditional LTE system is received through the base station or The transmission method is different. The IoV system adopts the terminal-to-terminal direct communication method, so it has higher spectral efficiency and lower transmission delay. [0003] In 3GPP Rel-14, the vehicle networking technology (V2X, Vehicle-to-Everything) is standardized, and two transmission modes are defined: Mode 3 and Mode 4. In mode 3, the transmission resource of the terminal is allocated by the base station. In mo...
