摘要： Provided is a communication system for a multi-cell cooperative communication. A serving base station and at least one neighboring base station may communicate with at least one terminal through mutual cooperation. Each of the serving base station and the at least one neighboring base station may shift a phase of at least one element among elements included in a precoding matrix, using a phase shift matrix, and precode at least one data symbol. A terminal may feed back preferred phase shift matrix information to the serving base station, so that the serving base station and the at least one neighboring base station may adaptively determine a phase shift matrix. The terminal may calculate the phase shift matrix with small calculation amounts. The serving base station, the at least one neighboring base station, and the terminal may pre-store a plurality of candidate matrices with respect to the phase shift matrix.

摘要： Disclosed is a method for depositing a tungsten silicide layer on a wafer coated with a polysilicon layer in a CVD process chamber. A surface of the polysilicon layer is pre-treated by introducing a hydrogen compound gas including any elements among group III elements or group V elements of the periodic table into the CVD process chamber. The tungsten silicide layer is deposited on the polysilicon layer by introducing a silane source gas and a tungsten source gas into the CVD process chamber. Since the surface of the polysilicon layer is pre-treated using the hydrogen compound gas before the tungsten silicide layer is deposited on the polysilicon layer, void generation is prevented on an interfacial surface between the tungsten silicide layer and the polysilicon layer.

摘要： Disclosed is a method for controlling uplink transmit power in a mobile communication system. A mobile communication includes a first base station and a second base station which are located in two mutually adjacent cells, respectively, at least one base station of the first and second base stations which generate a subframe offset of transmit power (SOTP), and transmits a subframe offset of transmit power generated by at least one base station of the first and second base stations to at least one terminal which belongs to a corresponding cell. Accordingly, it is possible to reduce signaling times for transmit power control, and to accurately control transmit power.
