Problems solved by technology

The uplink and downlink guard intervals of traditional wireless frames are determined by the coverage distance of the cell. When the length of the wireless frame is greatly reduced, assuming that the cell coverage distance remains unchanged, if the traditional method continues to be used, the proportion of the guard interval overhead will increase significantly. Will seriously affect system performance and user experience

Abstract

The invention provides a method and a device for setting protection interval, and a base station. The method comprises the following steps: acquiring one or more of transmission delay, time advance and distance of a plurality of terminals connected to a base station relative to the base station; clustering the terminals according to one or more of the transmission delay, time advance and distance to get at least one cluster, wherein each cluster includes at least one terminal; and setting the configuration information of the protection interval of a scheduling sub frame corresponding to each cluster according to the longest transmission delay or the maximum time advance or the greatest distance corresponding to the terminals in each cluster. According to the method, the base station clusters the terminals according to the transmission delay, time advance and distance of the terminals relative to the base station. The length of protection interval can be configured flexibly. The system cost and the risk of inter-station interference in the system are reduced. The round-trip delay is reduced. The user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and base station for setting a guard interval. Background technique [0002] RTT (Round Trip Time, round-trip delay) is an important performance index to measure the quality of mobile communication services. RTT is the time from when the sender sends data to when the sender receives an acknowledgment from the receiver. Here, after receiving the data, the receiving end processes and parses it and then sends an acknowledgment immediately. [0003] Existing mobile communication is mainly communication between people. With the miniaturization and intelligence of hardware devices, the future 5G mobile communication will be more of a high-speed connection application between "people and things" and "things and things". Such as real-time cloud computing, augmented reality, virtual reality, online games, telemedicine, intelligent transportation,...
