A radio network with many endpoints, such as many user terminals (UTs) accessing a constellation of many satellites, may experience self-interference due to reduced apparent angular separation between endpoints. For example, many UTs that are covered by a satellite's antenna gain pattern of an uplink may interfere with one another if those UTs use the same frequencies at the same time. The UTs may be geographically separated, but due to relative position between them and the satellite, they appear within the same gain pattern. Resource mapping is performed to allocate link resources to mitigate self-interference. A conflict graph is determined and used to allocate link resources, such as particular combinations of timeslot and frequency, to reduce or eliminate self-interference. The conflict graph may be determined using one or more analytical or heuristic techniques. Resource allocation may be performed for links such as satellite uplinks, satellite downlinks, or both.
