Problems solved by technology

But the main disadvantage of this method is to load data packets with different QoS requirements into one MAC PDU, and send the MAC PDU with the same transmission parameters at the physical layer
Transmit services in logical channels with different QoS requirements through the same transmission parameters, which makes it difficult to match services and resources

Embodiment Construction

[0155] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0156] See figure 1 , figure 1 It is a schematic diagram of an application scenario of a data packet transmission method provided by an embodiment of the present invention. Such as figure 1 As shown, the application scenario includes: a terminal device 101 and a base station 102 . Data transmission is performed between the terminal device 101 and the base station 102 in a wireless communication manner.

[0157] The above-mentioned terminal device 101, also called user equipment (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, and the like. Common terminals include, for example, mobile phones, tablet computers, notebook computers, palmtop computers, mobile internet devices (mobile internet devices, MIDs), wearable dev...

Abstract

The invention discloses a data packet transmission method. A terminal device receives uplink scheduling resource configuration information sent by a base station. The uplink scheduling resource configuration information includes information for indicating the uplink scheduling resource used by the terminal device and communication physical information for indicating the uplink scheduling resource. characteristic information; the terminal device determines the data transmission priority corresponding to each logical channel in the N logical channels; the terminal device transfers the data transmission priority corresponding to each logical channel in the N logical channels to the The data of the M logical channels is loaded into the MAC PDU; the terminal device sends the MAC PDU to the base station on the uplink scheduling resource according to the communication physical characteristics of the uplink scheduling resource. The embodiment of the invention also provides a device. By adopting the embodiment of the present invention, the data transmission of the logic channel with high priority is guaranteed, the waste of resources is avoided, and the maximum matching of resources and services is realized.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a data packet transmission method and equipment. Background technique [0002] In a traditional communication system, a single user has multiple different types of services at the same time, and these services require different quality of service (Quality of Service, QoS), such as delay and rate. Generally speaking, services with different QoS requirements will be divided into different logical channels, some logical channels have higher data transmission priority, and some logical channels have lower data transmission priority. If the round-robin scheduling method is used, the business service quality corresponding to the logical channel with high data transmission priority may be difficult to meet, and if the service demand corresponding to the logical channel with high data transmission priority is always given priority, low data transmission will occur The service requiremen...
