Problems solved by technology

In this case, the sporadic fading in the 10-30GHz frequency band is unavoidable and will inevitably affect the quality of communication services
[0011] Furthermore, as the communication users move or turn around, the channel quality of the service beam will also change, and even lead to occasional beam connection failures. When the number of beams is constant, the user is far away from the beam communication range, or the beam corner affects the link quality Or when the communication user moves, if the original service beam is still used for communication, the quality of communication service may not be guaranteed
In addition, considering that there is still a non-ideal backhaul between LTE MeNB and NR SeNB, the backhaul delay introduced may be tens or even hundreds of milliseconds, and overtime packets are also treated as packet loss or error packets, so it is reliable Sex ratio requirements also affect communication service quality just like delay
[0012] In summary, when users communicate through NR SeNB, high frequency fading or user movement may destroy the communication QoS

example 1

[0044] Taking the power wireless private network communication system on the 230 frequency band as an example, the wireless power private network communication system may be interfered by other systems or some unforeseen interference. When a user equipment terminal (UE) works on one carrier, if it is subjected to strong interference, the QoS of the UE may not be guaranteed. The UE needs to perform frequency hopping to hop the working frequency band to a frequency band with low or no interference. The QoS guarantee factor can provide a reference for the UE's frequency hopping scheme and improve the UE's QoS.

[0045]The base station periodically scans the available channel carriers, selects a suitable channel to access, and performs measurement configuration for the UE (it can be periodic measurement or event-triggered measurement); when the measurement result of the UE shows that its When the QoS cannot be guaranteed, the UE will feed back an enhanced QoS status report messag...

[0051] Taking the close interoperability between LTE and NR as an example, the LTE MeNB serves as the primary base station, and the NR SeNB serves as the secondary base station. It is assumed that the communication links between the UE and the LTE MeNB and the NR SeNB have been established, and initially, the quality of the links between the UE and the MeNB or SeNB is good. Therefore, the communication QoS under the two technologies can be guaranteed. However, when fading leads to sudden deterioration of the Signal to Interference plus Noise power Ratio (SINR) of the serving beam or user movement causes the service quality of the beam to degrade, the NR communication QoS cannot be guaranteed. Therefore, it is necessary to optimize the QoS guarantee mechanism to maintain the communication QoS.

[0052] In actual implementation, if one bit is used as the QoS guarantee bit to indicate the QoS guarantee coefficient, different situations can be indicated in the following different...

Abstract

The invention relates to a QoS guarantee method in a power wireless communication system. The method comprises the following steps: step S1: maintaining a communication connection between a user equipment terminal with a base station through a current active link; step S2: measuring the channel state of an available channel carrier through the user equipment terminal, and obtaining a QoS guaranteecoefficient of the current active link; step S3: when the QoS guarantee coefficient of the current active link is less than a preset QoS guarantee bit, sending an enhanced QoS state report message tothe base station through the user equipment terminal, wherein the enhanced QoS state report message comprises: the QoS guarantee coefficient of the current active link, and an alternative channel carrier ID; and step S4, determining an optimal frequency hopping scheme by the base station according to the channel quality of the current active link and the QoS guarantee coefficient of the current active link, so that the user equipment terminal performs frequency hopping. By adoption of the QoS guarantee method provided by the invention, the quality of service of the user equipment terminal inthe wireless communication system can be effectively guaranteed.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a QoS guarantee method in a power wireless communication system. Background technique [0002] At present, the interference of the 230MHz frequency band used by the power wireless communication system is various, such as the interference caused by the existing 230M digital radio station; the ultra-high transmission power of military communication causes strong interference; unforeseeable sudden interference, etc. (such as Jiaxing model aircraft) interference, etc.). The anti-jamming solutions for the 230MHz frequency band mainly include the following technologies: [0003] Frequency hopping: Uplink and downlink transmission supports inter-channel frequency hopping technology. For low-cost narrowband terminals with limited radio frequency bandwidth, support packet frequency hopping technology to reduce mutual interference between power wireless private netw...
