Embodiment Construction

[0053] The embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0054] In the embodiment of the present application, a terminal, also referred to as User Equipment (UE), is a device that provides voice and / or data connectivity to users, for example, a handheld device with a wireless connection function, a vehicle-mounted device Wait. Common terminals include, for example: mobile phones, tablet computers, notebook computers, palmtop computers, mobile internet devices (mobile internet devices, MIDs), wearable devices, such as smart watches, smart bracelets, pedometers, and the like.

[0055] Network equipment is mainly responsible for providing wireless connections for terminals and ensuring reliable transmission of uplink and downlink data of terminals. The network equipment can be gNB (generation Node B) in the 5G system, it can be the base station (Base Transceiver Station) in the Global System of M...

Abstract

A data packet transmission method and device, wherein the method includes: the terminal acquires N running applications, where N is an integer greater than 0; if there is an application including low-latency services among the N applications, then Instructing the network device to schedule the data packet of the terminal to be transmitted in the authorized frequency band. When the terminal determines that there is an application program containing low-latency services among the running N application programs, it can instruct the network device to schedule the data packets of the terminal to be transmitted in the authorized frequency band, so as to realize the transmission of low-latency services through the authorized frequency band For data packets, since the resources in the licensed frequency band are uniformly scheduled by network equipment and are not used through competition, the transmission of data packets for low-latency services through the licensed frequency band can ensure the latency requirements of low-latency services , so as to solve the problem of high delay caused by transmitting data through unlicensed frequency bands.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a data packet transmission method and device. Background technique [0002] In a long term evolution (Long Term Evolution, LTE) system, an unlicensed frequency band may be used to transmit data through a licensed assisted access (Licensed Assisted Access, LAA) technology, thereby improving service throughput in the LTE system. Currently, unlicensed frequency bands mainly include: 2.4GHz-2.4835GHz, and 5.725GHz-5.850GHz. [0003] However, in the LTE system, before the terminal adopts LAA technology to use the channel of the unlicensed frequency band to transmit data, it needs to monitor whether other devices use the channel of the unlicensed frequency band to transmit data. If so, it needs to wait for a period of time before monitoring until It is determined that no other device uses the channel of the unlicensed frequency band to transmit data before...
