A wireless communication device includes a channel state information (CSI) estimation circuit and a transmitter (TX) circuit. The CSI estimation circuit performs CSI estimation for generating CSI data. The TX circuit transmits a first frame at a specific physical layer (PHY) data rate to another wireless communication device. The first frame carries the CSI data. The specific PHY data rate is higher than a basic PHY data rate for normal acknowledgement (ACK) frame transmission.

Wireless communication device using higher physical layer data rate for channel state information transmission and associated wireless communication method

The present invention provides an electronic device including a first antenna, a second antenna and a wireless communication chip. The wireless communication chip is configured to control the first antenna to broadcast a packet, control the second antenna to receive the packet broadcasted from the first antenna, and determine channel state information according to the packet received by the second antenna.

A wireless communication calibration system has a radio chipset, an analog circuit set, and a calibration path. The radio chipset has a transmitter and a receiver. The analog circuit set is external to the radio chipset and coupled to the transmitter, and receives an output signal of the transmitter and generates a transmission signal according to the output signal. The calibration path is external to the radio chipset and coupled to the analog circuit set, and guides an input signal to the receiver, wherein the input signal is derived from the transmission signal, and a first delay is calculated after the input signal is received by the receiver.
