Abstract
Embodiments of the present disclosure relate to compressed channel state information transfer. According to embodiments of the present disclosure, the radio unit at the base station receives signals from the terminal device. The radio unit (RU) compresses the signal based on the weights of beams and transmits the compressed signal to the baseband unit (BBU) at the base station. The baseband unit reconstructs the channel based on the compressed signal and the coefficients. In this way, the amount of information conveyed across the RU-BBU interface is reduced, and the accuracy of channel estimation is improved. Further, the sounding reference signal (SRS) channel can be obtained at the BBU with reduced number of SRS transmissions.
