On-demand system information delivery for extended coverage

摘要

Systems and methods for delivery of on-demand system information in a cellular communications network are disclosed. In some embodiments, a method of operation of a network node comprises transmitting, to a User Equipment (UE), minimum system information including a set of signal quality indication levels and corresponding random access parameter(s) and detecting a random access request from the UE that uses the random access parameter(s) configured for the signal quality indication level that corresponds to a signal quality level measured at the UE. The method further comprises deciding whether to deliver on-demand system information to the UE via a broadcast or dedicated signaling based on the signal quality level measured at the UE, broadcasting on-demand system information upon deciding to deliver on-demand system information via a broadcast, and delivering on-demand system information to the UE via dedicated signaling upon deciding to deliver on-demand system information via dedicated signaling.
