Problems solved by technology

[0005] However, in the R12 release of Long Term Evolution (LTE) of the 3rd Generation Partnership Project (3GPP), only the broadcast communication mode is specified for D2D communication without providing support for priority
Therefore, it is currently impossible to meet the priority requirements of the application level in D2D communication at the access level

Embodiment Construction

[0035] The basic idea of ​​the embodiments of the present disclosure is to introduce a support mechanism for data packet priority at the access layer level of D2D communication, so as to use the data packet priority to support preferential transmission of data packets across different UEs. More specifically, based on the priority of data packets transmitted by all UEs on the D2D network, each D2D UE controls its ongoing and / or to-be-transmitted data packets, so that data can be realized on the entire D2D network. Priority transmission of packets, that is, transmission according to priority.

[0036] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] For ease of understanding, a typical scenario in a D2D communication network is first described here. In a typical scenario, multiple D2D...

Abstract

Embodiments of the present disclosure relate to a method and device for controlling data packet transmission in D2D communication. The method includes: the current user equipment acquires data packet priority information about other user equipment; and based on the data packet priority information, controls the data packet transmission of the current user equipment. According to the embodiments of the present disclosure, a support mechanism for data packet priority can be introduced at the access layer level of D2D communication, so that the data packet priority can be used to support the priority transmission of data packets across different UEs, thereby satisfying the priority of the application layer needs and facilitate the use of users.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of wireless communication, and more specifically relate to a method and device for controlling data packet transmission in Device-to-Device (Device-to-Device, D2D) communication. Background technique [0002] With the rapid popularization of smart terminals and the explosive growth of network communication capacity, the evolution requirements for the fifth generation (5G) wireless communication technology are more clear and urgent. [0003] In the evolution of 5G-oriented wireless communication technology, as a key candidate technology for 5G, D2D communication has the potential to improve system performance, improve user experience, and expand cellular communication applications, so it has attracted widespread attention. [0004] In the wide application of D2D communication (such as the scene where firefighters use walkie-talkie communication during their official duties), sometimes it is neces...
