摘要： A transmitter directed, distributed receiver using multi-user diversity provided by the distribution of the receiver. Advantage is taken of the uncorrelated variations over time in the condition of communication links between a common transmitter and several users. The greater the variation in the quality of a particular link over time, the greater the increase in total system throughput provided. An scheduler metric (or scheduler metric) 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 access to the channels.

摘要： A transmitter directed, distributed receiver using path diversity provided by the distribution of the receiver. Advantage is taken of the uncorrelated variations over time in the condition of channels between a common transmitter and several users. The greater the variation in the channel condition of a particular channel over time, the greater the increase in total system throughput provided. An access metric represents the instantaneous channel condition of the communication system between each user and the transmitter with respect to the average channel condition of each channel. Alternatively, the access metric represents the instantaneous channel condition with respect to the average data throughput over that channel. The common transmitting station uses the access metric to directly compare the desirability of granting each channel access with the desirability of granting each other channel access. The user that has the greatest access metric is provided access to the channel.

摘要： Adaptive delay management means and method for allocating resources having different Quality of Service (QoS) requirements. A Forward Link (FL) scheduler prepares transmission instances by treating pending data queues according to a priority class, such as Best Effort (BE) and Expedited Forwarding (EF). Data bits from multiple queues are stuffed into a transmission instance. Various metrics are used to generate a set of candidates for transmission and then select and build a next transmission instance from the set of candidates.
