Abstract  Abstract

Access request transmissions are effected in a wireless communications syst em by assigning each mobile unit a unique dedicated uplink resource. Specifically each mobile unit is assigned channel segments with distinct time slot indices and/or waveform indices where waveforms with distinct indices are orthogonal. A ba se station can identify the mobile that has made an access request from the dedicated uplink resource. Therefore no mobile identification number is needed in the uplink request message. Then the base station can transmit a request response message on a shared downlink resource that may include the identification number of the requesting mobile unit to acknowledge reception of the request. The mobile unit may transmit on a shared uplink resource an acknowledgment of reception of the downlink reques t response message.
