US 12,004,007 B2 · Mobile assisted enhancements to reduce radio resource control (RRC) signaling

Abstract

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).

Claims7

Dependent claims

A method to be performed by a User Equipment (UE), comprising:

receiving a Radio Resource Control (RRC) paging message from a base station that indicates a System Information (SI) modification for at least one On Demand SI;
in response to the RRC paging message, monitoring a broadcast channel for a given duration without initiating a Random Access Channel (RACH) procedure to obtain the at least one On Demand SI, wherein the given duration begins upon receiving the RRC paging message;
attempting to decode the at least one On Demand SI from the broadcast channel during the given duration;
and
if the On Demand SI is not successfully decoded during the given duration, initiating the RACH procedure with the base station to obtain the at least one On Demand SI.
