Multi-Link Reconfiguration Using Link Capability Compatibility Checks

The patent applies preliminary action by performing compatibility authentication before completing the multi-link reconfiguration. The first MLD determines whether link capability of requested links is compatible with link common capability and whether operational requirements are compatible before actually adding or removing affiliated APs/STAs. This preliminary check prevents incompatibility issues from arising during the reconfiguration process.

The compatibility authentication is performed as a preliminary action before the actual reconfiguration, but the patent optimizes this process by only conducting the authentication when necessary (e.g., when adding new links or changing operational parameters). The first MLD determines compatibility based on pre-existing link common capability and operational information, avoiding redundant checks and minimizing time overhead.

The patent applies universality by establishing a unified link common capability and link common operation framework that applies to all links within the multi-link device. The first MLD uses a standardized determination process that works consistently across different link types and configurations. This universal approach simplifies coordination by providing a single set of rules and methods rather than requiring link-specific coordination logic.
