Aperiodic SRS Triggering Offset for PDCCH Congestion Reduction

The patent applies dynamics by making the slot offset configurable and adaptable rather than fixed. The network can dynamically adjust the slot offset value based on current system conditions, traffic patterns, and resource availability. This allows the system to optimize between timing simplicity and triggering capacity by selecting appropriate offset values differentially for different SRS resource sets and transmission scenarios.

The patent implements parameter changes by introducing configurable slot offset parameters that can be modified through RRC signaling. Instead of a single fixed offset, multiple offset parameters can be defined and selected based on different SRS resource sets, transmission purposes, and network conditions. This parameter flexibility enables the system to resolve the contradiction by adjusting the offset parameter to balance control simplicity with triggering capacity.

The patent applies segmentation by dividing SRS resource sets into multiple groups, each with its own configured slot offset. This allows the network to segment the triggering of different UEs across multiple slots rather than concentrating all triggers in a single slot. By segmenting the SRS transmissions temporally through different offset configurations, the PDCCH overhead is distributed and reduced while maintaining overall transmission efficiency.

The patent implements periodic action by configuring different slot offsets that create periodic SRS transmission patterns across multiple slots. Instead of simultaneous triggering, UEs are triggered at periodic intervals determined by their respective slot offset configurations. This periodic distribution of triggers reduces instantaneous PDCCH overhead while maintaining efficient SRS transmission throughput over time.
