摘要

Aspects of the subject disclosure may include, for example, determining a self-interference channel response of a transceiver of a mobile base station having a transmitter and a receiver. The self-interference channel response spans multiple sub-bands of a predetermined mobile cellular frequency channel. A first sub-band of the multiple sub-bands is identified according to the self-interference channel response and, an estimate is determined, at the receiver, of a first coupled transmit power level of the transmitter when operating within the first sub-band. A receiver sensitivity is adjusted according to the first coupled transmit power level to obtain an adjustment adapted to increase receiver sensitivity, while restricting operation of the receiver to a substantially linear region. The adjustment allows a transmission within the first sub-band and a reception within a second sub-band of the plurality of sub-bands to occur simultaneously at the mobile base station. Other embodiments are disclosed.

說明書

A self-interference channel 248 is illustrated as a line drawn between the transmit antenna 243a and the receiver antenna 243b. The self-interference channel 248 corresponds to a coupling of a transmitted RF signal, e.g., a downlink (DL) RF signal 249a into a front end of the receiver module 242. According to the self-interference channel 248, a portion of the DL RF signal 249a may couple into a front end of the receiver module 242 in combination with an uplink (UL) RF signal 249b, also present at the front end of the receiver module 242. The actual coupling mechanisms that give rise to the self-interference channel 248 may include one or more of antenna-to-antenna coupling, cable-to-cable coupling, internal device coupling, reflections from environmental objects, and so on.
