Reduced-Capability UE Access via 1 Rx/2 Rx Branch Selection

The patent segments the access barring indication into separate indications for 1 Rx branch use and 2 Rx branches use. The network entity can independently control access barring for each receiver branch configuration, allowing devices to selectively access based on their capabilities. This resolves the contradiction by enabling fine-grained control (improving reliability) while allowing devices to adapt their access mode (improving adaptability).

The patent introduces dynamic access determination where the UE evaluates multiple barring indications (for 1 Rx and 2 Rx) and selects the appropriate access mode based on current network conditions and device capabilities. The access barring status is not fixed but dynamically determined by comparing different configuration options, resolving the contradiction between network control and device flexibility.

The patent makes the access barring indication universal by designing it to serve multiple functions: it can indicate barring for 1 Rx devices, 2 Rx devices, or both simultaneously depending on the configuration. The same indication mechanism handles multiple device types, achieving precise control (improving measurement precision) without proportionally increasing signaling overhead.

The patent uses parameter changes within the existing barring indication structure to convey different meanings. By modifying parameters such as the presence/absence of specific flags or the combination of barring values, the system achieves precise differentiation between 1 Rx and 2 Rx device barring status without adding separate signaling channels, thus maintaining efficiency while improving precision.
