Abstract: 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 a 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.

Abstract: A method performed by a station that includes receiving information from a cell of a Public Land Mobile Network (PLMN), determining whether the information indicates the cell supports circuit switched fallback (CSFB) voice calls, when the CSFB voice calls are not supported, determining whether at least one packet switched voice property of the station satisfies a predetermined condition and attaching to the cell of the PLMN when the predetermined condition is satisfied. A further method performed by a station connected to a PLMN that includes identifying cells of the PLMN available for the station to camp on, determining whether the station is capable of executing packet switched calls, when the station is not capable of executing packet switched calls, determining whether the identified cells have a neighbor cell that supports CSFB voice calls and prioritizing the cells that are identified as having neighbor cells that support CSFB voice calls.

Abstract: A user equipment (UE), or other network component can operate to configure a plurality of new radio (NR) links of a E-UTRAN new radio (NR) dual connectivity (EN-DC) comprising a first radio access technologies (RAT) and a second, different RAT. A first link quality metric (LQM) evaluation of the first RAT is generated independently of generating a second LQM evaluation of the second RAT. A radio frequency (RF) interface, is configured to provide, to RF circuitry, data for a transmission of the first LQM evaluation and the second LQM evaluation based on a data split at a protocol layer so that a network component of base station can utilize the data to configure a data flow over the links based on link quality metrics provided.

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).

Abstract: A system and method for operation of a user equipment (UE) to determine a cellular network bottleneck in a downlink channel, and an apparatus for use in a UE for determining the same. A UE may determine a burst of network traffic from network traffic received from the cellular network during a series of transmission time intervals. The UE may analyze resource allocations to the UE during the burst to determine an extent to which the cellular network is busy. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the analysis of the resource allocations to the UE in the burst.
