Robust position determination in communication systems

A remote radio head, comprising:

• an antenna configured to exchange radio frequency signals over wireless channels to communicate with at least one user equipment (UE);
• an analog front end coupled to the antenna;
• a communications interface configured to exchange data with a central office;
• a position determination unit further comprising:
• a satellite positioning system (SPS) receiver configured to generate position values of the remote radio head based on signals received from a satellite positioning system;
• and
• a supplemental positioning unit configured to generate additional position values of the remote radio head;
• a memory configured to store instructions;
• and
• at least one processor, coupled to the analog front end, the communications interface and the memory, wherein the at least one processor is configured to execute the instructions stored in the memory to:
• determine whether an error of at least one of the position values exceeds a threshold,
• store a last position value from position values having an error within the threshold, in response to determining that the error of at least one of the position values exceeds the threshold, and
• calculate an updated position value of the remote radio head based on at least one of the additional position values.
