Abstract: Apparatus, and an associated method, for facilitating closed-loop power control in a radio communication system, such as upon reverse links defined in a CDMA2000, cellular communication system. Rate indications are modulated by a modulator upon a control channel carrier signal to form a modulated data segment. Then, the modulated data segment is repeated a selected number of times to form a concatenated sequence of modulated data segments. The modulated data segments are of sub-frame lengths and the concatenated sequences of a frame length. When the concatenated sequence is communicated and delivered to a communication station, the information contained in a sub-frame portion can be used to improve power control operations upon the reception of the sub-frame rather than waiting for an entire frame of information to be delivered to the communication station.
