Embodiment Construction

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below.

[0020] An embodiment of the present invention provides a scheduling method based on channel information feedback. The scheduling method is implemented by a scheduling system composed of a base station and multiple terminals. The embodiment will not be explained too much, and the current technical manual can be referred to.

[0021] Take the unilateral side of the base station as the execution subject, such as figure 1 shown, including:

[0022] S101. The base station configures a channel state information reference signal, and broadcasts the configuration result to the outside.

[0023] The configuration result includes a channel state information reference signal port, a channel state information reference signal picture and a channel state information reference signal period.

[0024] S103. Receive a fe...

Abstract

The invention provides a scheduling method based on channel information feedback. The scheduling method comprises the steps that a base station configures a channel state information reference signaland externally broadcasts a configuration result; feedback signals published by various terminals are received, wherein each feedback signal comprises a terminal identifier and a precoded matrixe selected by the terminal, and the precoded matrixe comprises a first precoded matrix or a second precoded matrix; and the base station conducts user scheduling according to the acquired precoded matrixes,wherein a target scheduling user is selected, and a scheduling signal is sent to a target terminal corresponding to the target scheduling user, and the scheduling signal comprises a demodulation reference signal and a physical downlink line sharing channel signal. According to the scheduling method, the terminal conducts different feedback on the basis of different scheduling signals, usage of single feedback scheduling based on CSI-RS measurement channel information in the prior art is avoided, and the scheduling load of a system can be reduced; and in addition, the scheduling process is encrypted, and therefore the security is significantly improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a scheduling method based on channel information feedback. Background technique [0002] In 3GPP, users usually measure and feed back channel information based on CSI-RS. Obviously, as the number of antennas increases, the scheduling overhead of the system will increase significantly. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a scheduling method based on channel information feedback. [0004] The present invention is realized by following technical scheme: [0005] A scheduling method based on channel information feedback, comprising: [0006] The base station configures the channel state information reference signal, and broadcasts the configuration result to the outside; [0007] receiving a feedback signal issued by each terminal, where the feedback signal includes a terminal identifier and a precoding matri...
