Uplink Inter-site Carrier Aggregation Data Threshold

The patent dynamically changes the parameter of resource request transmission by selecting different target base stations (primary cell vs. secondary cell) based on the data amount to be transmitted. When data amount is below a threshold, requests are sent to the secondary cell; otherwise, they are sent to the primary cell. This parameter change optimizes power distribution and reduces interference while maintaining adequate transmission bandwidth.

The patent introduces a threshold parameter for data amount that dynamically determines the target base station for resource requests. This parameter change ensures that when data amount is small (below threshold), requests are directed to the secondary cell for optimized efficiency, while when data amount is large (above threshold), requests are directed to the primary cell to ensure sufficient power availability.

The patent simplifies the carrier aggregation complexity by introducing a straightforward decision parameter (data amount threshold) that determines resource request routing. This parameter-based approach avoids complex coordination mechanisms while maintaining the bandwidth benefits of carrier aggregation, as the UE autonomously decides whether to send requests to primary or secondary cell based on buffer status.
