Method for transmitting service data for various radio access technologies via common public radio interface |
摘要 |
<p>A method for transmitting radio service data for various Radio Access Technologies (RATs) via a Common Public Radio Interface (CPRI) Radio Equipment control (REC)-Radio Equipment (RE) interface is disclosed, thereby radio service data for different RATs can be transmitted via the CPRI REC-RE interface. The method includes: arranging IQ data of M RAT periods in N CPRI basic frames for transmission according to a common multiple relationship between a CPRI basic frame period and an RAT period, such that the service data rate matches the CPRI rate so as to implement frame synchronization; packing the IQ data of the M RAT periods in service data containers of the N CPRI basic frames as evenly as possible, wherein various packing patterns may be designed according to the demand of service, etc. such that the IQ data are transmitted in a rate as even as possible after mapping into the containers; transmitting the IQ data for the different RATs over a CPRI REC-RE interface by dividing IQ data areas corresponding to different REs and different RATs in the CPRI basic frame IQ containers over the same CPRI REC-RE interface.</p> |
