Abstract: A method is provided for managing a wireless network traffic by comprising designating a first resource block of a first base station for access by a random access channel (RACH). The method additionally comprises designating a first plurality of random access subframes associated with the first resource block for access by a user-over-control plane message, and receiving a random access signal at the first base station over a subframe from an endpoint. The random access signal is received on the RACH using a wireless network and is attempting to access one of the first plurality of designated random access subframes. Further, the method comprises determining if the random access signal is a user-over-control plane message, and processing the random access signal on the one of the first plurality of designated random access subframes.

Abstract: A method may include detecting a synchronization signal from a base station. The method may further include determining a synchronization detection probability based on the detection of the synchronization signal. The method may further include estimating a coverage deficit range based on the synchronization detection probability. The method may further include transmitting coverage deficit signaling configured to indicate the coverage deficit range estimated based on the synchronization detection probability.
