摘要： Techniques discussed herein can reduce RRC signaling messages, and various aspects can employ one or more of these sets of techniques. A first set of techniques can be employed to reduce RACH (Random Access Channel) requests from an RRC Idle State SIM (Subscriber Identity Module) of a UE in DSDS (Dual SIM Dual Standby) mode. A second set of techniques can be employed to reduce the number of RACH attempts to obtain NotBroadcasted (e.g., On Demand) SI(s) (System Information(s)) by a UE in response to a page message indicating SI modification.

摘要： Techniques disclosed herein relate to reducing RRC signalling messages. Techniques can be employed to reduce the number of Random Access Channel (RACH) attempts to obtain NotBroadcasted (e.g., On Demand System Information(s) (SIs)) by a UE in response to a paging message indicating SI modification. The UE may monitor the Physical Broadcast Channel (PBCH) for a given duration in attempt to decode the On Demand SI(s) without initiating a RACH procedure. If the UE fails to decode the On Demand SI(s) within the given duration, the UE may initiate a RACH procedure to obtain the On Demand SI(s).
