More Information
Summary:A method for transmitting data in a radiofrequency (RF) communication system, includes at least one piece of equipment, referred to as the BBU, configured to generate I/Q samples from data to be sent, and to extract a payload from I/Q samples, a plurality of pieces of equipment, referred to as RRH, configured to generate and transmit an RF analogue signal on the basis of I/Q samples, and to generate I/Q samples from a received RF signal, digital communication links between BBU and RRH, each BBU being configured to transmit/receive data through one of the RRH, the I/Q samples exchange being organized in the form of sample packets marked by a sequence identifier, BBU and RRH implementing a mechanism for acknowledgement of the exchanged packets, and to change RRH depending on the state of the acknowledgements. The communication system and equipment implementing the method are also provided.
