Embodiment 1

[0060] This embodiment provides a virtual MIMO communication method, please refer to figure 1 , the method includes:

[0061] S101. Obtain channel estimates of multiple user terminals communicating with a base station.

[0062] The so-called channel estimation is a process of estimating model parameters of an assumed channel model from received data. Acquiring channel estimates is generally done through pilots.

[0063] S102. Select a predetermined number of user terminals from each user terminal according to the channel estimation value of each user terminal and a preset condition.

[0064] In this embodiment, since the communication is performed based on the MIMO technology, at least two user terminals are selected, that is to say, the predetermined number is greater than or equal to two. As for how to determine how many user terminals need to be selected, this needs to be determined according to the first parameter of the base station currently demodulating the received ...

Abstract

The present invention provides a virtual multiple-input multiple-output communication method, device and system, which can consider the situation of each user terminal in real time by acquiring the current channel estimation of each user terminal. In this case, a predetermined number of user terminals are selected according to preset conditions to virtualize a MIMO user terminal, and the MIMO user terminal communicates with the base station according to the MIMO technology. This pairing selection strategy is based on real-time channel estimation, takes into account the current situation of each user terminal, and can improve the communication effect between the base station and the virtual MIMO user terminal.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a virtual multiple-input multiple-output communication method, device and system. Background technique [0002] MIMO (Multiple-Input Multiple-Output) technology refers to setting multiple transmitting antennas and receiving antennas at the transmitting end and receiving end respectively, so that signals are transmitted and received through multiple antennas at the transmitting end and receiving end, thereby improving communication quality. MIMO can make full use of space resources and realize multiple transmission and multiple reception through multiple antennas. It can double the system channel capacity without increasing spectrum resources and antenna transmission power. It is the core technology of next-generation communication. Although MIMO technology has significant advantages in system capacity and spectrum utilization, it is unrealistic to configure multipl...
