Embodiment Construction

[0033] Step 1: Predict the location coordinates of the user at the next moment, and obtain the number of users in the target cell

[0034] (11) The position coordinate l of each user at the current moment t t (x t ,y t ) as the input feature of the LSTM network, collect all user coordinates every 5 minutes, take the time step as n, then the input of the LSTM network is l t (x t-n ,y t-n )... l t (x t ,y t ), the output is l t+1 (x t+1 ,y t+1 ), then the input of the LSTM network is l t (x t-20 ,y t-20 )... l t (x t ,y t ), the output is l t+1 (x t+1 ,y t+1 ). Train the LSTM network with enough historical location records of users. Since the training process of the LSTM network is an existing mature process, it will not be repeated here. Train the LSTM network with enough historical location records of users;

[0035] (12) When predicting, input the position coordinates of each user in the past n moments, in this embodiment, input the position coordinates ...

Abstract

The invention provides a base station antenna dynamic switching method based on user behavior prediction. The method comprises the steps: for the movement rule and the flow use rule of the user, respectively predicting the position coordinate information and flow consumption information of the user in the next time period; judging the number of users in the target cell in the next time period canbe judged according to the coordinate information of the users; estimating the data rate demand of the user in the next time period according to the predicted flow consumption information of the user.In order to improve the accuracy of flow prediction, users are clustered according to the historical use conditions of the flow, and a prediction model is trained for each type of users. According tothe method, the number of the antennas to be started by the base station at the next moment is predicted according to the predicted number of the users in the target cell and the rate requirements ofthe users, so the energy consumption of the base station is reduced under the condition of ensuring the user requirements.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for dynamically switching base station antennas based on user behavior prediction. Background technique [0002] In massive MIMO systems, hundreds of antennas are installed at the base station to increase system capacity. Conventional massive MIMO networks are designed for maximum throughput, so turning on all antennas wastes a lot of energy when the base station is located in a cell with little traffic load. If the number of enabled antennas can be dynamically adjusted according to the load in the cell, the purpose of energy saving can be achieved. Most of the current schemes for dynamically adjusting base station antennas only consider the number of future users in the cell, without considering the needs of users. Contents of the invention [0003] Purpose of the invention: In order to solve the above problems, the present invention provides a method for dynam...
