Abstract

The invention relates to electronic equipment, a wireless communication method and a medium. The electronic equipment comprises a circuit, which is configured to execute the following operations of: obtaining a first channel state, wherein the first channel state at least comprises the channel state of a channel from a first device to a first antenna associated with the electronic equipment; and the first device and the electronic equipment perform wireless communication; and, obtaining a second channel state based on the first channel state, wherein the second channel state comprises the channel state of a channel from a second antenna associated with the electronic equipment to the first device.

Description

technical field [0001] The present disclosure generally relates to electronic devices, wireless communication methods and media, and more particularly, to signal processing techniques in duplex systems. Background technique [0002] Frequency Division Duplex (FDD) and Time Division Duplex (TDD) technologies are widely used in current wireless communication standards. In cellular communication, uplink and downlink transmissions work in different frequency bands in FDD mode, and work in different time slots in TDD mode to avoid interference between uplink and downlink transmissions. In the case of applying massive multiple-input multiple-output technology, the channel characteristics and signal processing technology under FDD / TDD are deeply studied by the academic and industrial circles. [0003] However, the FDD / TDD system uses orthogonal frequency / time resource blocks, which reduces resource block utilization and reduces system capacity. In order to further utilize frequen...
