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.

The cloud computing environments 375 can interface with the virtualized network function cloud 325 via APIs that expose functional capabilities of the VNEs 330, 332, 334, etc., to provide the flexible and expanded capabilities to the virtualized network function cloud 325. In particular, network workloads may have applications distributed across the virtualized network function cloud 325 and cloud computing environment 375 and in the commercial cloud, or might simply orchestrate workloads supported entirely in NFV infrastructure from these third party locations.

In at least some embodiments, the wireless access 120 includes a transceiver 380 adapted for full-duplex operation. The transceiver 380 may be adapted to implement one or more operations or instructions to support full-duplex operation. For example, the operations may operate the transceiver 380 to determine a self-interference channel response as a measure of a portion of transmitter output coupled to a receiver input. It is envisioned that the self-interference channel response spans multiple sub-bands of a predetermined mobile cellular frequency channel in which the wireless access 120 is permitted to operate. The operations further include identifying a first sub-band of the multiple sub-bands according to the self-interference channel response and adjusting a receiver level to increase receiver sensitivity, while restricting operation of the receiver to a substantially linear region.
