Threshold-Based Cell Measurement to Reduce Terminal Power Consumption

The patent segments the set of all cells on a frequency into multiple subsets, each associated with different SSB frequencies. The terminal device performs measurement on cells in different subsets at different times based on SSB detection results, rather than measuring all cells simultaneously. This segmentation reduces the number of cells measured at any given time, thereby reducing power consumption while maintaining overall measurement completeness.

The terminal device first detects SSB frequencies and identifies candidate cells before performing detailed cell measurements. By preliminarily filtering cells based on SSB detection results, the device determines which cells need to be measured in subsequent steps, avoiding unnecessary measurements and reducing power consumption.

The patent divides the cell measurement process into multiple stages and frequency groups. Cells are segmented into different measurement sets based on their association with specific SSB frequencies. The terminal device measures cells in an ordered manner across different frequency groups rather than simultaneously measuring all cells, reducing resource waste while maintaining mobility management accuracy through comprehensive eventual coverage.

The terminal device performs cell measurements periodically across different frequency groups and SSB associations. Rather than continuous real-time measurement of all cells, the device cycles through different frequency groups and measurement sets in a periodic manner, reducing resource consumption while ensuring all cells are measured within a measurement cycle for accurate mobility management decisions.
