TRANSMISSION METHOD AND DEVICE FOR FREQUENCY DOMAIN Russian patent published in 2014 - IPC H04B7/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention discloses a central baseband processing unit (CBPU), containing a switching module and at least one baseband unit (BBU), and additionally - a resource display module. The latter is configured to restore resource blocks for baseband signals of an upperlink frequency domain, obtained via FFT, and to demultiplex each user's signals from the corresponding subcarriers. The switching module is configured to transmit each user's signals to the corresponding BBU, whereas the BBU is configured to process the received user's signals. Accordingly, the invention implementation versions also disclose RRU and transmission method in a frequency domain.

EFFECT: transmission efficiency improvement for a C-RAN system.
