Some aspects of the disclosure provide for wireless communication systems in which scheduling information is transmitted to a scheduled entity to schedule transmission of uplink feedback control information by the scheduled entity. The feedback control information may be transmitted in short uplink control bursts or long uplink bursts. Selection between short uplink control bursts and long uplink bursts may be based on power headroom at the scheduled entity, interference in the short uplink control burst or the long uplink burst, loading of the short uplink control burst or the long uplink burst or processing capability of the scheduled entity.
