Control data for the communications traffic may be processed in response to the restricted TWT SP, with a TXOP ending at the beginning of a restricted TWT SP of a another link, in response to the restricted TWT SP being negotiated in a different link. Such an approach may be carried out where one of the wireless circuits has no STR configuration. A protected duration time for the TWT SP may be set to a time that is less than a duration of the TWT SP in response to the TWT SP being protected by a quiet element duration period.
