Abstract

The invention discloses a beam optimization method and system based on a reconfigurable holographic metasurface. The method comprises the following steps: dividing transmitting direction angles and receiving direction angles of a base station and a user into different sectors; the base station transmits a signal to the user; taking the receiving and transmitting sector pair with the strongest user signal receiving power as a first optimal receiving and transmitting sector pair; the user transmits a signal to the base station; taking the receiving and transmitting sector pair with the strongest signal receiving power of the base station as a second optimal receiving and transmitting sector pair; determining an optimal transmit-receive sector pair of a downlink and an optimal transmit-receive sector pair of an uplink according to the first optimal transmit-receive sector pair and the second optimal transmit-receive sector pair; and dividing the optimal transmit-receive sector pair of the downlink and the optimal transmit-receive sector pair of the uplink into a plurality of beams, and determining an optimal transmit-receive beam pair. By adopting the method, the optimal beamforming scheme can be obtained, so that the total data rate of users of the system is maximized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a beam optimization method and system based on a reconfigurable holographic metasurface. Background technique [0002] To realize ubiquitous intelligent information networks, the upcoming sixth generation (6G) wireless communication imposes stringent requirements on antenna technologies, such as capacity enhancement and precise beam steering. While the widely used dish antennas and phased array antennas are both capable of achieving these goals, they both suffer from their own inherent deficiencies that seriously hinder their future development. Specifically, dish antennas require heavy and expensive beam steering machinery, while phased arrays are highly dependent on power amplifiers, consume a lot of power, have complex phase shifting circuits, and have many phase shifters, especially in high frequency bands. Therefore, more cost-effective antenna technologies are requi...
