摘要
Certain aspects of the present disclosure relate to adapting transmitter configuration for efficient concurrent primary user detection through adaptive self-interference cancellation. A wireless transmitting device may schedule a transmission in a shared spectrum. The device may scan at least a portion of the shared spectrum during the transmission to receive a signal. Interference caused by the transmission may he cancelled from the received signal using self-interference cancellation circuitry. The device may determine whether the received signal indicates usage by a primary user of the shared spectrum. In an aspect, the transmission may be a SISO transmission. In another aspect, carrier aggregation may be used for the transmission and a potential carrier may be subject to primary user detection. The device may determine a self-interference cancellation complexity for a combination of carriers including the potential carrier, and may select one or more carriers for aggregation based on the self-interference cancellation complexity.
