摘要： A method for switching cells by a mobile equipment of a communication system. The mobile transmits a signal coded with a spreading code indicating the mobile's intent to switch cells and the coded information also identifies to which cell the mobile wants to switch. The coded information contains channel measurement adjustment information that is continuously transmitted to the cell which is currently serving the mobile. The flow of channel measurement adjustment information is therefore not disturbed by the application of the method of the present invention. Because the coded information identifies the target cell and indicates the mobile's intent to perform a cell switching procedure, the amount of processing done by the cells is significantly reduced thus increasing the likelihood of a successful switching procedure.

摘要： The present invention discloses an exhaust gas inlet structure of an exhaust gas recirculation (EGR) Cooler which includes a water shell, a gas inlet pipe, a bellow, an insulated pipe, an inlet chamber, a pre-cooling water chamber and a main board. The water shell is equipped with a water inlet pipe. Its main feature is the insulated pipe is placed within the bellow and connected with the gas inlet pipe at one end while the other end is suspended. The large-bore end of the inlet chamber is connected with the main board to form a gas inlet cavity while leaving a space to form a coolant channel between the joining part and the water shell. An external surface of a middle pipe body connects to the bellow to form a pre-cooling cavity connected to the coolant channel. The advantages of the present invention are as follow: newly-added pre-cooling water chamber reduces the wall temperature of the main board and the inlet chamber; newly-added supporting in the middle part of the insulated pipe improves the vibration-proof function of the insulated pipe; the special structure of the inlet chamber increases the ability of the axial displacement compensation. The above-mentioned improvement of the present invention significantly improves the reliability of the EGR cooler.

摘要： The present disclosure discloses a transmission power configuration method for a Demodulation Reference Signal (DMRS), and the method comprises: configuring the ratio between transmission power of a DMRS at each layer in a Resource Element (RE) and transmission power of data at a corresponding layer to be a constant value. Meanwhile, the present disclosure discloses a transmission power configuration apparatus for the DMRS. The present disclosure greatly improves the correct rate of data frame decoding, and improves decoding performance. The present disclosure enables the network side not need to notify a UE of the corresponding relationship between transmission power of DMRS at each layer and transmission power of data at the corresponding layer, which simplifies the overhead of the control signalling in the network side. As the corresponding relationship between transmission power of DMRS at each layer and transmission power of data at the corresponding layer is configured in the UE, the UE can implement channel estimation without waiting for the notification from the network side, which improves the channel estimation efficiency.

摘要： Methods and systems for femto-cell identification are disclosed herein. In one embodiment, a femto-cell base station is adapted to transmit with each broadcast a value which maps one-to-one to a different portion of a femto-cell identification. After the mobile station reports each broadcasted value to the serving non-femto-cell, the target femto-cell identification can be determined by combining multiple reports. In this manner, a fairly large identification space can be provided without significant increases in implementation complexity. In some embodiments, the system does not introduce issues with backward compatibility since standard cell identification procedures are preserved. In some embodiments, knowledge of the maximum number of femto-cells within a non-femto-cell is not required, thereby preventing ambiguous hand-in targets.

摘要： The present invention discloses a plate-fin structure EGR cooler with heat-insulation function includes shell. The two ends of the shell are equipped with an air inlet flange and a discharge chamber. A water inlet pipe and a water outlet pipe are set on the shell near the air inlet flange and the discharge chamber. A cooling core assembly, an air chamber and a bellow are set in the shell. The main board at one end of the cooling core assembly is connected to the shell and the discharge chamber and the main board at another end is connected to one end of the air chamber. The other end of the air chamber is connected to one end of the bellow. The other end of the bellow is connected to the shell and the air inlet flange. A heat-insulating pipe connected to the air inlet flange is set within the bellow. Since the main board at the other side of the cooling core assembly is flexibly connected to the shell via the air chamber and the bellow, the axial deformation generated in the flat pipe unit can be transferred to and absorbed by the bellow through the air chamber and thus the axial heat stress generated from the heat deformation of the flat pipe unit is eliminated.
