Semi-Persistent Scheduling Resource Allocation for Varying Packet Sizes

The patent implements dynamic resource allocation by allowing the UE to send scheduling requests when the pre-configured SPS resource is insufficient for the current packet size. The network then dynamically adjusts the resource allocation based on actual traffic needs, transforming the static SPS mechanism into a hybrid dynamic-semi-static system that adapts to varying packet sizes while maintaining the efficiency benefits of SPS for periodic traffic

The patent changes the resource allocation parameters dynamically by introducing scheduling requests that trigger network responses with adjusted resource configurations. When traffic volume exceeds the pre-configured SPS resource capacity, the system modifies resource parameters (such as resource blocks, time slots) through scheduling requests and grants, enabling adaptation to varying packet sizes while preserving SPS efficiency for normal periodic traffic

The patent implements a self-service mechanism where the UE autonomously monitors its own buffer status and determines when additional resources are needed by comparing available SPS resources with pending data volume. The UE then autonomously sends scheduling requests without network intervention, and the network only intervenes when resource adjustment is actually needed, reducing overall system complexity while maintaining high data transmission capability

The patent establishes a feedback loop where the UE reports scheduling requests based on its buffer status, and the network responds with resource allocation adjustments. This feedback mechanism enables the system to adapt to varying packet sizes efficiently while keeping complexity localized - the UE handles monitoring and request generation, while the network handles resource management decisions, distributing complexity rather than centralizing it

The patent applies partial action by implementing scheduling requests only when necessary - specifically when the UE determines that the pre-configured SPS resource cannot accommodate the available data for transmission. Instead of continuously signaling or using full dynamic scheduling for all transmissions, the system uses scheduling requests partially and only when resource insufficiency occurs, reducing signaling overhead while maintaining resource accommodation flexibility

The patent leverages the periodic nature of SPS traffic patterns by configuring scheduling requests to be triggered periodically based on buffer status checks at each SPS transmission opportunity. Rather than using continuous or on-demand signaling for every possible resource adjustment, the system uses periodic buffer status reporting aligned with SPS intervals, reducing signaling overhead by exploiting the inherent periodicity of the traffic pattern
