DEVICE, SYSTEM AND METHOD OF INTERFACING BETWEEN A BASEBAND (BB) MODULE AND A RADIO-FREQUENCY (RF) MODULE OF A WIRELESS COMMUNICATION DEVICE
First Claim
1. A wireless communication device including a radio-frequency (RF) module connectable to a base-band (BB) module, the RF module including:
- at least one transmit antenna;
a plurality of receive antennas;
at least one uplink input connectable to the BB module to receive from the BB module uplink signals to be transmitted via the at least one transmit antenna;
a plurality of downlink outputs connectable to the BB module to provide the BB module with downlink signals corresponding to wireless signals received via the plurality of receive antennas; and
a control interface connectable to the BB module to receive from the BB module a filter-calibration control signal,wherein, responsive to the filter-calibration control signal, the RF module is to output via one or more of the plurality of downlink outputs one or more respective filtered calibration signals corresponding to a filter calibration signal received via the uplink input.

Abstract
Some demonstrative embodiments include interfacing between BB and RF modules of a wireless communication device. In some embodiments the RF module includes at least one transmit antenna; a plurality of receive antennas; at least one uplink input connectable to the BB module to receive from the BB module uplink signals to be transmitted via the at least one transmit antenna; a plurality of downlink outputs connectable to the BB module to provide the BB module with downlink signals corresponding to wireless signals received via the plurality of receive antennas; and a control interface connectable to the BB module to receive from the BB module a filter-calibration control signal. The RF module may output via one or more of the plurality of downlink outputs one or more respective filtered calibration signals corresponding to a filter calibration signal received via the uplink input. Other embodiments are described and claimed.
