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

Abstract

The invention provides a resource allocation method based on terminal reference signal detection, a base station, and a terminal. The method is characterized in that when a business arrives, the base station notifies the terminal to carry out business frequency point availability reporting; according to the situation of available and idle schedulable frequency points, and considering a required bandwidth of the terminal, the base station determines a frequency point range to be reported by the terminal, and notifies the terminal to carry out the business frequency point availability reporting; after receiving a reporting result, the base station carries out judgment according to the frequency point availability; and if continuous frequency points do not include unavailable frequency points or the number of the unavailable frequency points does not reach a designated threshold, the corresponding terminal is allowed to be scheduled to channels corresponding to the continuous frequency points; and the terminal analyzes a downlink reference signal sent by the base station for determination of the frequency point availability. The method, the base station and the terminal provided by the invention has the advantages that unsuccessful resource allocation or low business transmission efficiency caused by interference is avoided, so that the transmission quality of the terminal is guaranteed, the spectrum resource utilization efficiency is improved, and radio resources are effectively saved.

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.
