Apparatus and method for fast access in a wireless communication system

摘要

Systems and methodologies are described that facilitate a fast access in a wireless communication system, such as OFDMA. According to various aspects, the system and methods are described for generating an access probe comprising an access signature having quality of service information and transmitting the access probe on a random access channel. Also, the system and methods of receiving an access probe, the access probe comprising quality of service information, generating an access grant in response to the receive access probe, addressing the access grant using information from the access probe, and transmitting the access grant.

主权项

1. A method of fast access in a wireless communication system, the method comprising:
generating an access probe preamble which comprises an access signature that facilitates selection of bandwidth resources and modulation and coding for one or more messages, wherein the access probe preamble indicates downlink information that enables power control of an access grant message sent on the downlink in response to the access probe preamble; transmitting the access probe preamble on a random access channel; and retransmitting the access probe preamble at higher power if an access grant is not received within a predetermined time period.
