Happy Bit Uplink Control Signaling for Dynamic Resource Scheduling

The patent extracts the Happy Bit transmission to only those specific occasions when the UE actually needs additional resources. Instead of transmitting control information on every uplink transmission, the UE sets and transmits the Happy Bit only when buffer status indicates need for more resources, thereby reducing unnecessary control information overhead while maintaining accurate resource need determination.

The patent applies partial action by transmitting control information with Happy Bit only partially - specifically when the UE's buffer status threshold is exceeded. This selective transmission approach avoids the excessive action of sending control information on every transmission, optimizing the balance between resource allocation accuracy and control overhead.

The patent implements a feedback mechanism where the UE sends the Happy Bit to the Node B, which then adjusts scheduling decisions based on this feedback. The Node B monitors incoming Happy Bits from multiple UEs and dynamically modifies resource allocation accordingly, enabling flexible scheduling while keeping the decision-making process relatively simple through this clear feedback signal.

The UE autonomously determines when it needs additional resources by evaluating its own buffer status against predefined thresholds, and self-initiates the Happy Bit transmission only when needed. This self-service approach reduces the scheduling complexity at the Node B, as the UE independently makes initial resource need assessments rather than requiring complex Node B-side analysis.

The patent implements dynamic adaptation of transmission parameters based on available resources. The UE adjusts its data transmission rate dynamically - transmitting at higher speeds when the Happy Bit indicates sufficient resources are available, and reducing transmission rate or deferring transmission when resources are constrained, thereby optimizing the balance between transmission speed and power consumption.

The patent changes the transmission parameter (data rate) based on the Happy Bit status and available resources. When resources are abundant, the UE increases transmission power and data rate to achieve faster transmission. When resources are limited, the UE reduces transmission parameters to conserve power, dynamically adapting to resource availability conditions.
