Compressed system information for link budget limited UEs in a radio access network

Abstract:

Techniques are disclosed relating to broadcasting and receiving system information in a radio access network (RAN). In one embodiment, a base station includes at least one antenna, at least one radio, configured to perform cellular communication using a radio access technology (RAT), and one or more processors coupled to the radio. In this embodiment, the base station is configured to broadcast first system information blocks (SIBs) encoded using a first coding rate and a first identifier. In this embodiment, the base station is also configured to broadcast second SIBs encoded using a second coding rate that is lower than the first coding rate and a second identifier. In this embodiment, the second SIBs include only a portion of the information included in the first SIBs and the second SIBs are usable by user equipment devices (UEs) having a limited link budget to determine access parameters for the base station.
