Problems solved by technology

For a transceiver system that integrates a large-scale antenna array, traditional digital baseband processing, such as precoding, requires a large number of baseband signal processing links. In a massive MIMO system, each transmit antenna is connected to a radio frequency link due to high hardware costs. not feasible

Abstract

The invention discloses transmission device and method for energy efficiency multi-mode hybrid beam formation in a wireless communication system. The method is that an emission device with adaptive transmission and beam formation capacity is provided; the baseband beam is formed in a digital domain by multi-space-time stream mapping; the radio frequency beam is formed at an analog domain radio frequency end by phase control; the wireless data transmission rate can be increased through hybrid beam formation multi-stream transmission at the digital domain and the analog domain; the beam can be formed at the digital domain and the analog domain under a multi-stream condition; in case of full stream, the space-time stream and radio frequency links are respectively correspondingly transmitted by the traditional mode; in case of unfilled stream, some radio frequency links can be closed, and all the phase-controlled emission antenna arrays can be used for performing full-domain phase control; therefore, the array antenna gain is utilized to the maximum while the baseband link energy consumption is saved, and as a result, the energy saving and multi-mode compatibility advantages are achieved.
