Abstract
Access to a variable rate multiple access system is controlled based upon a current loading. The current loading level is used to determine a transmission rate set point. The transmission rate set point may include a maximum transmission rate and a transmission probability. The transmission rate set point is passed to the remote unit which may access the system. A remote unit with data to send determines a desired transmission data rate. If the desire transmission data rate is equal to or greater than the maximum transmission data rate, the remote unit transmits at the maximum transmission data rate with a probability equal to the transmission probability.
Claims6
A method of accessing a wireless communication system comprising:
- determining a desired transmission data rate;
- setting a current data transmission rate to a maximum transmission rate with a probability equal to a transmission probability if said desired transmission data rate exceeds or is equal to said maximum transmission rate;
- and
- transmitting data to a base station at said current data transmission rate.
A remote unit for wireless communication comprising:
- a receiver for receiving a maximum transmission rate and a transmission probability transmitted by a base station;
- a rate determination process unit for determining a desired transmission data rate;
- the rate determination process unit for setting a current data transmission rate to said maximum transmission rate with a probability equal to said transmission probability if said desired transmission data rate exceeds or is equal to said maximum transmission rate;
- and
- a transmitter for transmitting data to said base station at said current data transmission rate.
