Abstract: A computer-implemented method for operating in a reduced power mode (RPM) of a user equipment (UE) in communications with a base station pursusant to a normal power mode (NPM). The NPM is characterized by one or more normal-power parameters comprising a normal sampling frequency and a normal signal bandwidth.

Upon expiry of the duration of the RPM by the UE, the UE powers up into the NPM by resuming to the sampling frequency of the NPM and the signal bandwidth of the NPM.

Abstract: Aspects of the present disclosure are directed to wireless communications based on a restricted TWT SP and buffer status. As may be implemented in accordance with one or more embodiments, frames are transmitted based on a restricted TWT SP and buffer status for communications between wireless circuits. 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.
