A method and a system is provided for optimizing the throughput of a TCP flow from a TCP source to a TCP destination in a wireless network with the path of the flow encompassing a wireless link between a wireless transmitter and a wireless receiver. The throughput is optimized by using link-layer mechanisms at the wireless transmitter which are adaptive to the instantaneous TCP dynamics of the TCP flow. In particular, a cross-layer approach is disclosed which serves to tunnel information of TCP congestion control dynamics directly from the TCP based transport layer to the data link-layer which selects in response to these information modulation and / or coding schemas to transmit TCP segments via data link-layer blocks with improved TCP throughput.

An apparatus and method controls transmission power by a Base Station (BS) of a wireless communication system by considering a path loss between the BS and a terminal and interference affecting adjacent cells. A receiver receives information about interference from adjacent BSs and a terminal. A calculator calculates transmission power of the terminal using the information about interference received from the adjacent BSs and the terminal. The information about interference received from the adjacent BSs comprises Noise & Interference (NI) values, and the information about interference received from the terminal includes a path loss value.

The invention discloses a method, a device and a system for increasing the uplink rate. A base station sends measurement configuration information to user equipment through a first carrier so that the user equipment can use a configured uplink sub-frame to send an uplink measurement signal periodically, wherein the configured uplink sub-frame is included in an uplink sub-frame set which can be transmitted on a second carrier. When judging that the signal quality and / or signal intensity of the uplink measurement signal received within a predetermined time range are / is higher than a predetermined threshold, the base station sends carrier configuration information to the user equipment through the first carrier so the user equipment can configure the second carrier as an auxiliary carrier according to the carrier configuration information. The base station allocates uplink transmission resources on the first carrier and on the second carrier for the user equipment so the user equipment can use both the first carrier and the second carrier to carry out uplink transmission through corresponding configuration. Thus, the user's uplink rate is increased effectively, and the user's uplink rate experience is enhanced under the condition of low design complexity.

The present invention provides the energy conservation method of a pumping unit. According to the method, a frequency converter and an electric power measurement controller are arranged at the output end of the power supply switch circuit of a motor, a motor speed measurement controller is arranged between the motor and the power supply switch circuit of the motor to automatic track and control an intermitting power supply. The control mode is as follows: {1} when the counter balance of the pumping unit moves between C and D, the equivalent gravities at two sides of a beam equal are equivalent, the positive work of the motor is almost zero, then the electric power measurement controller controls the frequency converter to shut off the power supply of the motor and a pumping rod rises rapidly; {2} when the counter balance moves between A and B or near A under the inertia effect, the inertia consumption caused by gravitational potential energy becomes none gradually, the rotating speed of the motor slows down to the set speed, the speed measurement controller controls the converter to supply power to the motor again which drives the counter balance to re-rise to perform the next work cycle.
