Abstract:
1. A method for improving network access through multi-stage signaling comprising: receiving by a remote unit signaling from a network node, wherein the signaling indicates a set of spreading channel codes; selecting by the remote unit a first spreading channel code from the set of spreading channel codes based on a channel quality between the remote unit and the network node; transmitting by the remote unit an initial access signal using the first spreading channel code; receiving, by the remote unit from the network node, a forward link assignment for a forward link referencing one of the spreading channel codes from the set of spreading channel codes; receiving data from the network node via the forward link; transmitting by the remote unit a subsequent access signal using a second spreading channel code in order to trigger the establishment of a private link associated with the forward link; and performing at least one of authentication signaling and power control signaling via the private link.
