Patent ID: 8265683

Claim:
A method for transmitting a message in a wireless communication system comprising: establishing a random chip level backoff, at a wireless device, based on a number of chips (C) per interval and a random interval selected from a number of intervals (R); determining an access cycle duration (ACD) level random backoff; transmitting the message at a time designated by the chip level random backoff and ACD level random backoff; wherein determining the ACD level random backoff comprises: determining a backoff interval based on channel load of an access channel; determining a random backoff time, wherein the backoff interval defines a range from which the random backoff time is selected; delaying the transmission of an initial transmission message for the random backoff time, wherein the message is an access probe; and wherein determining a backoff interval further comprises: setting D as equal to N/R, wherein N is an estimated number of access terminals attempting to access the access channel and D is used to establish the backoff interval as access cycles.
