Physical Resource Configuration for Full-Duplex Interference Cancellation

The patent applies preliminary action by configuring dedicated physical resources in advance for unidirectional transmission signals and iterative convergence processes. The base station pre-allocates specific time-frequency resources for reference signals and cancellation operations before full-duplex communication begins, ensuring interference cancellation capability is established upfront rather than dynamically adjusted during operation.

The patent segments physical resources into distinct types: resources for unidirectional transmission signals, resources for iterative convergence, and resources for normal bidirectional communication. This segmentation allows each resource type to be optimized for its specific function while maintaining overall system flexibility through structured resource management.

The patent implements periodic action by allocating iterative convergence resources at specific intervals rather than continuously. The base station configures periodic reference signals and convergence opportunities that occur at predetermined times, allowing the system to reduce self-interference effectively while leaving other time-frequency resources available for normal data transmission, thus maintaining spectrum utilization efficiency.

The patent applies partial action by allocating only the minimum necessary resources for convergence and unidirectional transmission. Rather than dedicating extensive resources to interference cancellation, the system provides just enough specialized resources to achieve effective self-interference reduction, allowing the majority of spectrum resources to remain available for productive data communication.

The patent applies universality by designing reference signals that serve multiple functions simultaneously. The same reference signal structure is used for both channel estimation and iterative convergence of the analog cancellation circuit. This multi-functionality allows the system to optimize cancellation performance without adding separate dedicated signals, thereby avoiding increased device complexity.

The patent merges the functions of reference signals for channel estimation and convergence training into a unified resource configuration. By combining these functions into a single reference signal framework, the system achieves effective analog cancellation without the overhead of multiple separate signal structures, maintaining device simplicity while improving cancellation performance.
