1. A wireless communications system comprising:
a base station; and
a user equipment;
wherein:
the base station and the user equipment are configured to transmit and receive wireless communications via a bidirectional wireless link including a downlink signal, an uplink signal, and a plurality of narrowband spread spectrum reference signals; and
the user equipment is configured to:
receive the plurality of narrowband spread spectrum reference signals;
estimate a signal strength by combining the plurality of narrowband spread spectrum reference signals over multiple symbols;
estimate a propagation channel excess pathloss of the downlink signal based on the signal strength;
encode the propagation channel excess pathloss to a quantized deficit value by using a single binary digit; and
communicate the quantized deficit value to the base station.
