Abstract

The invention provides a method for establishing a backhaul network and communication and a communication device, and the method can comprise the steps that a first communication device receives first indication information, the first indication information is used for determining a working mode and / or working configuration information of the first communication device in the backhaul network, the first communication device comprises a first antenna array, and the first antenna array is used for receiving the working mode and / or working configuration information of the first communication device in the backhaul network; the first antenna array is an electromagnetic metasurface antenna array; the first communication device establishes the backhaul network according to the first indication information. According to the method provided by the embodiment of the invention, a method for establishing a backhaul network is provided by utilizing the electromagnetic metasurface antenna array, so that a flexible and high-performance D-MIMO transmission scheme is realized.

Description

technical field [0001] The present application relates to the communication field, and more specifically, relates to a method and a communication device for establishing a backhaul network and communication. Background technique [0002] In order to improve communication efficiency, a massive multiple-input multiple-output (MIMO) antenna system is introduced into a fifth generation (5th Generation, 5G) communication system. Further, in order to enable all users within the coverage of the cell or users moving within the cell to have better user experience performance, the transmission architecture based on centralized massive MIMO will evolve into distributed MIMO (distributed, MIMO, D-MIMO) system structure. However, the fixed backhaul network and wireless backhaul network proposed by the current 5G system have large delay and jitter and low transmission efficiency, respectively, and it is difficult to achieve flexible and high-performance D-MIMO transmission.
