Having suitably configured operation of the transmitter module 241 according to the selected sub-band and operation of the receiver module 242 in view of the self-interference related to the DL RF signal 249a, the mobile cellular communications transceiver 240 may initiate and/or maintain full-duplex operation.
FIG. 2H depicts an illustrative embodiment of a sub-band selection process 270 for in-band frequency duplex operation in accordance with various aspects described herein. According to the illustrative sub-band selection process 270, an in-band, self-interference channel is determined at 271. The self-interference channel may be determined according to any of the various techniques disclosed herein, such as performing a measurement that measures a portion of a transmitted signal coupled to the receiver. Other examples include, without limitation, obtaining an indication of the self-interference channel from a similarly configured system, and/or from a previous measurement and/or from an estimation.
