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.
A method comprising:
A transmitter comprising a buffer storing packets, a circuit that determines a condition of the buffer, a reception portion that receives information from a receiver, and a circuit using the condition and the information to determine at least one transmission parameter, wherein the determinations of the condition and the at least one transmission parameter are performed to achieve a desired delay constraint for packet traffic over a channel from the transmitter to the receiver.
A transmitter comprising:
A signal bearing medium tangibly embodying a program of machine-readable instructions executable by a processing apparatus to perform operations comprising:
A method comprising:
A method comprising:
A receiver comprising a reception portion, a channel estimator, and a circuit, the reception portion receiving first information from a transmitter, the first information corresponding to a condition of a buffer of the transmitter, the channel estimator determining channel state information for a channel from the transmitter to the receiver, the circuit determining second information using the first information and channel state information, the determination of the second information performed so that a desired delay constraint for packet traffic over the channel is achieved.
The receiver of claim 36, further comprising a transmission portion that communicates the second information to the transmitter.
A receiver comprising:
A method comprising:
A signal bearing medium tangibly embodying a program of machine-readable instructions executable by a processing apparatus to perform operations comprising:
A method comprising:
