Title: SYSTEMS, METHODS AND DEVICES FOR REDUCING NETWORK CONFIGURATION SEARCHES BY MAPPING PHYSICAL CELL IDENTIFIERS TO NETWORK CONFIGURATION INFORMATION
Abstract:
Physical cell identifiers (PCIs) are mapped to network configuration information to reduce search time for user equipment (UE). For example, a UE can derive a PCI from a synchronization process with a radio access network (RAN) node. The UE can then use the PCI to retrieve network configuration information from storage (such as a subscriber information module (SIM) card). The network configuration information can be a network configuration or a set of values for network configuration. If the network configuration information is a network configuration, the UE can use the network configuration to decode a physical broadcast channel (PBCH). If the network configuration information is a set of values for network configuration, the UE can try unique combinations of the values until the UE can decode the PBCH.
