    • PROBLEM TO BE SOLVED: To solve such a problem that a random access channel is intended to encompass a wider range of functionalities than in previous or current cellular networks, thus an expected load is increased, so that a more efficient random access method is needed.SOLUTION: A random access signal comprises a random access preamble signal selected from a set of random access preamble signals constructed by cyclically shifting selected root CAZAC sequences. The random access signal has a length of one or more transmission sub-frames, the length of the included random access preamble sequence is extended with the signal to provide excellent signal detection performance in larger cells and in higher interference environments. The random access signal includes a wide-band pilot signal facilitating base station estimation of up-link frequency response in some situations.

    • PROBLEM TO BE SOLVED: To adjust ultra high-speed bi-directional data transmissions between a central unit and a plurality of remote units, through distinct twisted pair transmission lines that share a binder.
      SOLUTION: Specifically, periodic synchronized uplink and downlink communication periods are provided so as not to overlap with each other. The uplink and downlink communication periods for all of the wires that share the binder are synchronized. With this arrangement, all of the ultra high-speed transmissions within the same binder are synchronized, and time division duplexed such that downlink communications are not transmitted when overlapping with the transmission of uplink communication. In some embodiments, quiet periods are provided to separate the uplink and downlink communication periods. The invention described may be used, in conjunction with a wide variety of modulation schemes, including both multi-carrier and single carrier transmission schemes. It is compatible with the existing systems and has particular advantages for ultra high-performance systems.

    • PROBLEM TO BE SOLVED: To provide a slurry for polishing which has less of the conventional defects and is improved which is used for chemical mechanical polishing (CMP) to be used for manufacturing a semiconductor integrated circuit, and to provide a polishing method using the same. SOLUTION: The slurry for polishing has a composition which uses colloidal silica instead of the conventional aerosol silica for the material of an abrasive, and uses a corrosion inhibitor while not using an oxidant which has been conventionally used. For wafer interconnection fabrication, a damask inlay method is employed. In the polishing method, a damask inlay structure and a polishing pad are prepared. The slurry is applied on the interface between the structure and the pad, and polishing is performed by a chemical mechanical polishing apparatus using the polishing parameters of the apparatus to remove at least part of a metal layer.
