Abstract
A communication circuit in a wireless communications system (WCS) is provided. The WCS employs self-interference cancellation (SIC) circuitry to suppress an interference signal(s) associated with an uplink communications signal(s) in a target uplink band(s). A communication circuit is employed to provide more accurate temporal and phase estimates about interference signal(s) in the target uplink band(s). The communication circuit utilizes an anchor downlink signal, which can be any of the downlink communications signals communicated in the WCS, to help determine an optimal phase shift for uplink communications signal(s) in the target uplink band(s). Accordingly, the SIC circuitry can suppress the interference signal(s) in the target uplink band(s) based on the optimal phase shift. By determining the optimal phase shift in the target uplink band(s), it is possible to achieve accurate temporal and phase synchronization in the SIC circuitry, thus helping to achieve higher and more stable interference suppression in the WCS.
