Sub-band selection at cellular base station for non-overlapped or partially overlapped full duplex operation
摘要
說明書
In at least some embodiments, the access point 122 includes a transceiver 181 adapted for full-duplex operation. The transceiver may be adapted to implement one or more operations or instructions 180 to support full-duplex operation. For example, the operations may operate the transceiver 181 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 access point 122 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.
In at least some embodiments, the transceiver 181 may be in further communication with another system, such as a backend server 182 adapted to support full-duplex operation. The backend server 182 may include storage adapted to store one or more of previously obtained self-interference channel responses, previously obtained receiver level adjustments, and the like for one or more operational frequency bands and/or sub-bands. In at least some embodiments, the backend server 182 may provide a machine learning function adapted to support, e.g., predict, one or more of the self-interference channel response and/or the receiver level setting.
