    • A first method comprises determining a condition of a buffer in a transmitter; using the condition, determining information corresponding to the condition; and communicating the information to a receiver. A second method is disclosed comprising receiving first information corresponding to a condition of a buffer in a transmitter; determining channel state information for a channel from the transmitter to the receiver; using the first information and the determined channel state information, determining second information; and communicating the second information to the transmitter. The second information and the condition of the buffer may be used by the transmitter to determine at least one transmission parameter, e.g., one or both of transmission rate and transmission power for a signal from the transmitter to the receiver. A desired delay constraint for packet traffic over the channel may be achieved.
    • 第一方法包括确定发射机中的缓冲器的状况; 使用该条件,确定与条件相对应的信息; 并将信息传送到接收器。 公开了一种第二种方法,包括:接收与发送器中的缓冲器的条件相对应的第一信息; 确定从发射机到接收机的信道的信道状态信息; 使用所述第一信息和所确定的信道状态信息,确定第二信息; 以及将所述第二信息传送到所述发射机。 发送器可以使用第二信息和缓冲器的条件来确定至少一个传输参数,例如,用于从发射机到接收机的信号的传输速率和传输功率中的一个或两个。 可以实现在信道上的分组业务的期望的延迟约束。
