Access is provided in a wireless communications system including at least one base station operative to communicate with one or more terminals over a forward control channel and a reverse control channel. A high-penetration channel reservation status is transmitted indicator from a base station in a plurality of slots assigned to a high-penetration forward control channel, such that the high-penetration channel reservation status indicator has a redundancy greater than that of a channel reservation status indicator transmitted over the forward control channel. Transmission of the high-penetration channel reservation status may be preceded by transmission of a high-penetration access request from a terminal in a plurality of slots assigned to a high-penetration reverse control channel, such that the high-penetration access request has a redundancy greater than that of an access request transmitted over the reverse control channel, and reception of the high-penetration access request at the base station. The high-penetration channel reservation status indicator may be transmitted responsive to receipt of the high-penetration access request. The channel reservation status information is coded according to an error correction code, preferably a combination of a convolutional code and a block code. According to another aspect, high-penetration hyperframe/superframe structures are utilized. Related base station and terminal apparatus are also discussed.
