Multi-Link BA Bitmap Timing for Accurate Frame Reception

The patent segments the receiving status determination process by introducing a time delay threshold parameter. The bitmap in the BA frame is segmented in functionality: bits corresponding to data frames transmitted before the threshold time indicate actual receiving status, while bits for frames transmitted at or after the threshold time indicate unspecified status. This segmentation allows the same bitmap structure to convey different types of information based on timing, resolving the contradiction between compact representation and accurate status determination.

The patent introduces a time delay threshold parameter that changes the interpretation of bitmap bits based on transmission timing. By varying the time parameter (comparing frame transmission time against the threshold), the system dynamically determines whether a bitmap bit represents confirmed receiving status or unspecified status. This parameter-based differentiation enables accurate multi-link status determination without increasing bitmap complexity.
