Patent ID: 7443823

Claim:
A method for a wireless transmit/receive unit (WTRU) to conduct wireless communications with a plurality of other WTRUs that implements a process for advertising available wireless communication data rates to the other WTRUs where the other WTRUs include a first type of WTRU capable of communicating at data rates in a first defined set of rates and a second type of WTRU capable of communicating at data rates in a second defined set of rates that include first type data rates that are useable by both the first and second types of WTRUs and second type data rates that are useable by the second type of WTRUs, but not the first type WTRUs, the method comprising: determining a number m of the first type of WTRUs and a number n of the second type of WTRUs wirelessly communicating with the rate advertising WTRU; determining a quality of a radio link between the rate advertising WTRU and the first and second types of WTRUs with which it is communicating; and advertising support of the second defined set of data rates when m=0 or when the determined radio link quality lies at a desired level and n=0.
