Abstract
Abstract A method, access point device and a perpherical device provide low complexity dynamic persistence for random access in a wireless communication system. The peripheral device includes: A) a block assignment receiver, for receiving a block assignment having a source address which contains a contention address and a persistence level and identifying the contention address and reading the persistence level; B) a random number generator, coupled to the block assignment receiver, for generating a random number based on the persistence level; and C) a persistence based transmitter, coupled to the random number generator, for transmitting a payload burst containing a resource request based on the random number and the persistence level.
