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 invention relates to a diversion plate of a solar water heater, in particular to a hot water diversion device capable of leading hot water in a heat collection pipe into a water storage tank for effective heat exchange. By the diversion plate, the problem of convection between hot water and cold water in the solar water heater is expected to be solved from sources, the hot water in an inner pipe of the heat collection pipe smoothly ascends along a sunny side, enters the water storage tank, rapidly floats along the diversion plate and exchanges heat with the cold water in a larger space, and the cold water in the water storage tank smoothly enters the heat collection pipe, descends along a shady side and fills the remaining space. The diversion plate consists of a connecting ring and a hot water channel; the hot water channel is a curved cambered surface axially extending along the connecting ring; the two side edges of the cambered surface hang down; the protruding direction of the cambered surface faces upwards; and the tail part of the cambered surface is bent upward and extends to a hot water area of the water storage tank. The diversion plate is installed on the ordinary solar water heater, and can improve the convection of water in the heat collection pipe and the water storage tank, increase the circulated speed of the water and improve the heat collection efficiency.

The invention discloses a time slot resource allocation method and device. The method comprises the following steps: a network side measures the signal receiving qualities of time slots used by a user terminal and calculates the quantity of the time slots the signal receiving qualities of which are higher than a set threshold; the network side calculates the size of a transmission block when a first time slot resource allocation mode is allocated to the user terminal according to the calculated quantity of the time slots the signal receiving qualities of which are higher than the set threshold; and the network side calculates the size of a transmission block when a second time slot resource allocation mode is allocated to the user terminal according to the quantity of all time slots used by the user terminal; and the network side selects a time slot resource allocation mode and a time slot resource corresponding to the time slot resource allocation mode according to the calculated sizes of the transmission blocks of the first time slot resource allocation mode and the second time slot resource allocation mode. By adopting the method and device disclosed by the invention, the wireless resource utilization ratio can be improved.

The invention discloses a method for reallocating resources. The method comprises the following steps that: a node base (NodeB) performs strong channel detection on user equipment (UE) and reports the obtained strong channel information of the UE to a radio network controller (RNC); and the RNC reallocates the resources for the UE according to the strong channel information of the UE reported by the NodeB. By the method, dedicated physical channel (DPCH) space division can be realized so as to improve carrier capacity and service quality; and a cell can be formed by performing path combination on a radio remote unit (RRU) with capacity of supporting different frequency bands.
