Rejected – The overhead of signaling unassigned AIDs to the STAs in the RAW with a new information element is large. For example, to signal just 5 AIDs, there needs to be at least 5x13bits for unknown gain. Moreover, considering unassigned AIDs within the RAW Group increases the complexity at a STA, which defeats the purpose of implicit slot allocation scheme. The unassigned AIDs can be avoided by utilizing the AID reassignment so that the RAW Group does not have unassigned AIDs.
