Title:
通信チャネルの伝送速度変更のための方法および装置
Document Type and Number:
Japanese Patent JP4485732
Kind Code:
B2
Abstract:
A method of accessing a system utilizing multiple data rates. The method includes determining a desired transmission data rate and setting a current data transmission rate to the desired transmission data rate if the desired rate is less than a maximum transmission rate. The current data transmission rate is set to the maximum transmission rate with a probability equal to a transmission probability if the desired transmission rate exceeds or is equal to the maximum transmission rate. Also described is a multiple access communication system including a base station which uses an indication of system loading to determine a transmission probability and a maximum transmission rate for the system and broadcasts the transmission probability and the maximum transmission rate to a plurality of remote units. A remote unit transmits data to the base station at the maximum transmission rate with the transmission probability. A multiple access communication system may include a receiver for receiving a maximum transmission rate and a transmission probability produced by a base unit, a process for determining a desired transmission data rate, a process for setting a current data transmission rate equal to the desired transmission data rate if the desired rate is less than a maximum transmission rate, and a process for setting the current data transmission rate to the maximum transmission rate with a probability equal to the transmission probability if the desired transmission rate exceeds or is equal to the maximum transmission rate. A transmitter transmits data to the base unit at the current data transmission rate.
