Problems solved by technology

[0004] For wireless communication transmission assisted by dynamic metasurface antennas, it is difficult to obtain instantaneous channel state information in most cases. In such cases, it is reasonable and feasible to use statistical channel state information to realize dynamic metasurface antenna-assisted system transmission in most cases
Most of the existing achievements are based on the assumption that the instantaneous channel state information is completely known, but there are few studies on transmission optimization using statistical channel state information

Abstract

The invention provides a large-scale MIMO uplink statistical transmission method assisted by a dynamic metasurface antenna. The dynamic metasurface antenna works at a base station side as a receiving antenna for uplink transmission, so that the transmission power consumption can be reduced, and the transmission performance is improved. In order to solve the problem that channel information of a current large-scale MIMO wireless transmission system is difficult to obtain, the invention proposes to optimize dynamic metasurface antenna assisted large-scale MIMO uplink transmission by using statistical channel state information, and the algorithm framework comprises methods of alternate optimization, certainty equivalence, Dinkelbach transformation and the like. According to the invention, large-scale MIMO uplink high-efficiency transmission assisted by the dynamic metasurface antenna based on statistical channel state information is realized with low complexity.

Description

technical field [0001] The invention belongs to the field of massive MIMO wireless communication, and in particular relates to a dynamic metasurface antenna-assisted massive MIMO uplink statistical transmission method. Background technique [0002] Future wireless communication tends to deploy a large number of antennas at base stations using energy-saving and environment-friendly technologies to a large extent. Dynamic metasurface antennas have the characteristics of low power consumption, small physical size, and low hardware cost, and are expected to realize energy-efficient large-scale antenna arrays in future communication networks. [0003] Dynamic metasurface antenna is a new design concept of aperture antenna. Its characteristic is that the physical properties (especially permittivity and permeability) of metamaterial units can be reconfigured according to the external environment, so it can exhibit a series of expected characteristic. Dynamic metasurface antennas ...
