How can I use the WLAN waveform generator to generate the packets for the transmission through the channel which has been extracted from CSI values?
Pay attention CSI values shows the complex of the h for every subcarrier. I have extracted CSI values from a CSI tool, and now I want to check the validity of the CSI by passing some packets through the channel and evaluating the PER. can you please somebody help me with the answer?

Three things you should make clear:
  1. The signal producted by wlanWaveformGenerator is the BASEBAND signal.
  2. The "channel" you talk about, or more specific, the center frequency (CF) of a given Wi-Fi Channel (say 5200 MHz for Channel 40 with HT20 mode) is a passband parameter.
  3. Assume you have access to a USRP, then you should first tune the USPR's CF to 5200MHz with 20MHz sampling rate, and then transmit the baseband signal.
The whole story is irrelavant to Wi-Fi NIC-based CSI tool, neither Intel 5300 based or QCA9300 based.
