Embodiment Construction

[0054] The present invention is described in further detail below in conjunction with accompanying drawing:

[0055] see figure 1 , when the UAV needs to send the collected information flow back to the UAV control and management center through the TD-LTE public network or private network, the MAC layer is oriented to the QoS guarantee of various information flows on the small civilian UAV Uplink scheduling methods such as figure 2 As shown, the method consists of the information flow generation module, classification mapping module, scheduling module, and channel state detection module at the UAV communication terminal, as well as the wireless resource configuration module, channel state detection module, and information flow recovery module at the eNodeB. Cooperative implementation under the control of this signaling mainly includes the following steps:

[0056] 1) Information flow classification mapping:

[0057] The information flow generation module at the UAV communi...

Abstract

The present invention discloses a UAV uplink scheduling method based on TD‑LTE technology oriented to QoS guarantee of information flow: an information flow generation module, a classification mapping module, a scheduling module and a channel state detection module at the UAV communication terminal , and the wireless resource configuration module, the channel state detection module and the information flow recovery module at the eNodeB are cooperatively implemented under the control of various signaling. The present invention adopts the 4G communication network TD-LTE, and proposes a UAV information flow classification mapping method and scheduling algorithm, which can provide differentiated transmission services for various types of information sent back to the control management center by the UAV during flight , to provide an effective link guarantee for the reliable flight of UAVs and the acquisition of high-quality collection information.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and relates to a scheduling method, in particular to a small civil unmanned aerial vehicle uplink scheduling method based on TD-LTE technology and oriented to multiple stream QoS guarantees. Background technique [0002] Small civilian UAVs are simple in structure, small in size, and low in cost; their flight and maintenance costs are low, and they are not afraid of harsh environments; they are flexible in use, easy to carry, and do not require special airports and large ground equipment. It will gain a huge application market in the fields of natural disaster prevention and treatment, urban and rural construction and planning, scientific observation, public security and frontier defense. [0003] As one of the important subsystems, the UAV communication system is the key for the UAV to communicate with the control management center in real time, to feed back flight status and in...
