TRANSMITTER DIRECTED CODE DIVISION MULTIPLE ACCESS SYSTEM USING MULTI-USERS DIVERSITY TO MAXIMIZE THROUGHPUT WHILE EQUITABLY PROVIDING ACCESS TO USERS
PROBLEM TO BE SOLVED: To provide a code division multiple access system using multi-users diversity to maximize throughput while equitably providing access to users.;SOLUTION: The present invention utilizes uncorrelated variations over time in the condition of communication links between a common transmitter and several users. One scheduler metric (or scheduler metrics) represents the instantaneous quality of the communication link between each user and the transmitter with respect to the average quality of the link. Alternatively, the scheduler metric represents the instantaneous channel condition with respect to the average data throughput over that channel. The common transmitting station uses the scheduler metric to directly compare the desirability of granting each channel access with the desirability of granting each other channel access. The users with links that have the greatest scheduler metric are provided with access to the channels.;COPYRIGHT: (C)2015,JPO&INPIT
