TDD Frame Structure Extended Transmission Overlap

The patent introduces dynamic frame structures that allow nodes to switch between different transmission-reception patterns. Nodes can dynamically adjust their frame configurations to enable simultaneous reception of reference signals from multiple nodes during specific time periods, while maintaining half-duplex operation during other periods. This dynamic adaptation resolves the contradiction by allowing mobility support functionality to emerge when needed without permanently compromising half-duplex constraints.

The patent extends communication beyond the traditional single time dimension by introducing extended reception parts that overlap with transmission parts of other nodes. This creates additional temporal dimensions where nodes can receive signals from multiple sources simultaneously. By adding this dimensional flexibility to the frame structure, nodes gain the ability to perform cross-node signaling and receive reference signals while maintaining overall TDD half-duplex operation.

The patent introduces extended reception parts in the frame structure that are positioned to overlap with transmission parts of other nodes. This preliminary structural arrangement ensures that when nodes need to communicate, the temporal window is already prepared and extended, allowing them to capture signaling opportunities without waiting for traditional switching points. This preliminary action eliminates communication time losses while maintaining half-duplex integrity.

The patent modifies frame structure parameters including extending reception parts, adjusting guard periods, and reconfiguring subframe allocations. These parameter changes create flexible frame configurations where the communication time window is expanded. By changing these temporal parameters dynamically, the system achieves both improved productivity through efficient resource allocation and extended communication windows without violating half-duplex constraints.

The patent segments the frame structure into distinct functional parts: default transmission parts, default reception parts, and extended reception parts. Each segment has a specific purpose and timing configuration. This segmentation allows nodes to manage complexity by treating each segment independently while benefiting from their coordinated interaction. The extended reception part is introduced as a separate segment that overlaps with other nodes' transmission parts, enabling cross-node signaling without redesigning the entire frame structure.

The patent designs the extended frame structure to serve multiple functions: it enables cross-node signaling, provides additional time windows for resource allocation, supports mobility measurements, and maintains half-duplex operation. By creating a multi-functional frame structure, the system achieves high adaptability for various communication scenarios without proportionally increasing complexity. The same extended structure handles multiple communication needs simultaneously, reducing the overall complexity burden.
