摘要： The present invention provides methods and apparatus for identifying the target mobile stations for data transmission in a wireless communication network. Two preambles with the first preamble being transmitted on one branch of the in-phase and quadrature signal and the second preamble, if transmitted, being transmitted on the other branch of the in-phase and quadrature signal, and the choice of which branch the first preamble is transmitted on collectively determines the MACIndex, which is the identity of the target mobile station in the system. The design of multiple MACIndex Extension Levels minimizes the performance impact due to the increased MACIndex numbers. Methods for detecting the secondary preamble by performing hypothesis testing are provided. An enhanced Multi-User Packet format that supports both the legacy MACIndex and the new expanded MACIndex in the same packet is described.
