Resource allocation method based on terminal reference signal detection, base station, terminal

Abstract

The present invention provides a resource allocation method based on terminal reference signal detection, a base station, and a terminal. In the present invention, the base station notifies the terminal to report the availability of service frequency points when the service arrives; the base station can schedule frequency points according to available and idle conditions, Combined with the required bandwidth of the terminal, determine the range of frequency points reported by the terminal, and notify the terminal to report the availability of service frequency points; the base station receives the reported results and judges according to the availability of frequency points. If the used frequency point does not exceed the specified threshold, the corresponding terminal is allowed to be scheduled to the channel corresponding to the continuous frequency point. Wherein, the present invention utilizes the terminal to analyze the downlink reference signal issued by the base station to determine the availability of the frequency point. The invention can avoid unsuccessful resource scheduling or low service transmission efficiency caused by interference, ensure terminal transmission quality, improve spectrum resource usage efficiency, and effectively save air interface resources.

Description

technical field [0001] The invention belongs to the technical field of interference coordination, and more specifically relates to a resource allocation method based on terminal reference signal detection, a base station, and a terminal. Background technique [0002] With the rapid development of wireless communication technologies, more and more industry applications also use wireless communication systems for service transmission. However, for wireless systems used in different industries, the interference on wireless channels is more complex, and the interference perceived by base stations and terminals is not exactly the same, which will cause asymmetrical wireless two-way link environments. In order to ensure the reliability of the communication interaction between the base station and the terminal under the cellular system, it is necessary that there is no interference within the respective sending and receiving ranges of the sending and receiving parties.

Problems solved by technology

However, the frequency environment in the application is relatively complex, and electromagnetic interference will cause the asymmetry of the wireless two-way link environment

Only based on the detection results of the uplink channel as the scheduling basis, it cannot correctly reflect the actual situation of the downlink channel. Scheduling the terminal may lead to unsuccessful service scheduling or poor service transmission effect after successful scheduling, and inefficient use of air interface resources.
