[0069] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0070] like Figure 1 As shown in FIG, the beam optimization method in the 5G power scenario includes the following steps:

[0071] Step 1: Acquire communication information of all communication users within a preset range of the target base station, and calculate the achievable rate of the wireless channel corresponding to each communication user based on the communication information of each communication user;

[0073] Step 3: Iteratively solve the short packet beamforming optimization model corresponding to each of the communication users to obtain the short packet beamforming vector corresponding to each of the communication users.

[0074] The above method effectively reduces communication delay by transmitting short packets and constructs a short packet beamforming optimization model. The model aims to maximize the weighted sum of the achievable rates corresponding to all the communication users. By iteratively solving the short packet beamforming optimization model corresponding to each communication user, the short packet beamforming vector corresponding to each communication user is obtained. Signal transmission is performed based on the short packet beamforming vector, which can effectively increase the transmission rate in the power system, improve transmission reliability, and meet the user's low latency requirements.

[0075] by Figure 2 As an example, a 5G power scenario in the example is deployed, in which a base station connected to the 5G power network is deployed. The base station is equipped with a multi-antenna array unit with a total of N t Antennas are used, and M single-antenna users are distributed in the power wireless network. To meet the low-latency, high-reliability communication requirements of multiple users, the base station uses multiple antenna array units and spatial division multiple access technology to achieve frequency division multiplexing gain.

[0077] Collect the communication information of all communication users within the preset range of the target base station, that is, collect the needs, distribution, coordinates, antenna angles, etc. of M communication users.

[0078] Since space division multiple access technology is used, the base station will add a weight before each transmission signal, that is, the transmission signal can be expressed as where w m The weight added before transmitting the signal to the mth communication user, x m is the signal transmitted to the mth communication user.

[0079] Therefore, when considering using time division multiple access technology to serve users, the transmission link between the base station and the communication user is constructed. The wireless channel coefficient corresponding to each communication user can be calculated based on the communication information of each communication user. Based on the wireless channel coefficient corresponding to each communication user, the signal-to-interference-and-noise ratio of the wireless channel corresponding to each communication user can be further calculated.

In addition, Represents the noise term in the signal received by the mth communication user.

[0082] In order to eliminate interference between multiple users in communication, a short packet beamforming scheme is used here. The channel dispersion parameter corresponding to each communication user under short packet transmission can be calculated based on the signal-to-interference-and-noise ratio corresponding to each communication user.

[0085] In order to ensure the fairness of performance of all users in the 5G power scenario, user weights are introduced. According to the achievable rate corresponding to each communication user, a short packet beamforming optimization model corresponding to each communication user can be constructed.

[0086] The model uses the short packet beamforming optimization model to maximize the weighted sum of the achievable rates corresponding to all the communication users as the optimization goal, taking into account the base station transmission power constraint and the service quality requirement constraint provided by the base station to the communication users. The specific formula can be expressed as follows:

[0087] Objective function:

[0095] R m ≥Γ m

[0096] Among them, Γ m The threshold value required for the communication user rate.

[0097] The above model is iteratively solved to obtain the optimal short packet beamforming vector, that is, the short packet beamforming vector corresponding to each communication user. The specific process can be as follows:

[0098] S1) Using auxiliary variable t m and a semi-positive definite variable W under rank 1 constraint m , convert the weighted sum of the reachable rates corresponding to all communication users into the form of subtracting two concave functions, and obtain the optimized weighted sum R of the reachable rates corresponding to all the communication users sum ;

[0104] S2) for the function T m and contains W m The concave function f m (Wm ) to perform first-order Taylor expansion and use the successive iteration method to obtain the function T m and f m (W m ), respectively denoted as and

[0105] S3) The approximate function is brought into the corresponding short packet beamforming optimization model, and the corresponding short packet beamforming optimization model is solved by the interior point method iteration method to obtain the short packet beamforming matrix corresponding to the communication user, that is, the preferred short packet beamforming matrix The termination condition of the interior point iterative method is that the difference between the weighted sum of the achievable rates corresponding to the communication users output in two consecutive iterations is less than a threshold;

[0106] S4) Optimize the short packet beamforming matrix Perform singular value decomposition to obtain the short packet beamforming vector corresponding to the communication user, that is, the preferred short packet beamforming vector

[0107] The base station can perform signal transmission according to the obtained short packet beamforming vector.

[0108] The above method effectively reduces communication delay by transmitting short packets and constructs a short packet beamforming optimization model. The model aims to maximize the weighted sum of the achievable rates corresponding to all the communication users and takes the user communication quality as a constraint. It aims to maximize the system communication performance on the basis of meeting the user's bit error rate and transmission time requirements. In the process of designing short packet beamforming, iterative optimization is continuously performed according to the base station transmission power constraint and the service quality requirement constraint provided by the base station to the user to obtain the preferred short packet beamforming vector, so that signal transmission can be performed based on the preferred short packet beamforming vector.
