Abstract: A communication system (100) that includes a base unit (101) and a subscriber unit (e.g., 103) employs a method (400) and apparatus (101) for mitigating interference (135) therein. The base unit (101) receives an uplink communication signal from the subscriber unit (103) at an uplink frequency and conveys a downlink communication signal to the subscriber unit (103) at a downlink frequency. Upon receiving (403) an uplink communication signal from the subscriber unit (103), the base unit (101) determines (405) a quality metric for the uplink frequency. When the quality metric is below a quality threshold (407), the base unit (101) and the subscriber unit (103) transfer (415) the communication signal to an alternate uplink frequency, while the downlink frequency remains unchanged.

Abstract translation: 包括基站单元（101）和用户单元（例如，103）的通信系统（100）采用减轻其中的干扰（135）的方法（400）和装置（101）。 基站装置（101）以上行频率从用户单元（103）接收上行通信信号，并以下行链路频率向用户单元（103）传送下行通信信号。 在从用户单元（103）接收（403）上行链路通信信号时，基本单元（101）确定（405）上行链路频率的质量度量。 当质量度量低于质量阈值（407）时，基站单元（101）和用户单元（103）将通信信号传送（415）到备用上行链路频率，而下行链路频率保持不变。
