Base station equipment and baseband signal processing module

A baseband equipment comprising:

• a radio frequency signal processing module which performs a radio frequency signal process;
• and
• a baseband signal processing module in communication with said radio frequency signal processing module, the baseband signal processing module comprising:
• a first interface which is configured to be connected to said radio frequency panel,
• a second interface and a third interface which are configured to be connected to different baseband signal processing modules, and
• a control module which transmits signals that have been processed with a baseband signal process performed by the control module to, and receives signals which are processed with the baseband signal process performed by the control module from, at least one of the radio frequency signal processing module via the first interface and one of said different baseband signal processing modules via the second interface, and which relays, via the third interface, signals, out of signal transmitted and received via the first interface or the second interface, which are to be processed with the baseband signal process performed by another of said different baseband signal processing modules.

A downlink signal processing method of a baseband signal processing module, the method comprising:

• receiving, at the baseband signal processing module, a first signal from a first external baseband signal processing module;
• receiving, at the baseband signal processing module, a second signal from inner-circuits of the baseband signal processing module;
• selecting and combining the first signal received from the first external baseband signal processing module and said second signal received from the inner-circuits of the baseband signal processing module;
• converting a format of said combined signal to provide a converted signal;
• multiplexing said converted signal together with a control signal;
• and
• transmitting said multiplexed signal.

A uplink signal processing method of a baseband signal processing module, the method comprising:

• receiving, at the baseband signal processing module, a first signal from an external baseband signal processing module;
• receiving, at the baseband signal processing module, a second signal from a radio frequency signal processing module;
• selecting and combining the first signal received from said external baseband signal processing module and the second signal received from said radio frequency signal processing module;
• converting a format of said combined signal to provide a converted signal;
• multiplexing said converted signal together with a control signal;
• and
• transmitting said multiplexed signal.
