An encoding method and apparatus for a DCH (Dedicated Channel) encoder and a DSCH (Downlink Shared Channel) encoder in a transmitter for a mobile communication system including the DCH encoder for encoding k bits among 10 input TFCI (Transport Format Combination Indicator) bits and the DSCH encoder for encoding remaining (10−k) bits among the input TFCI bits. The method comprises generating, by the DCH encoder, a first coded bit stream by encoding the k input bits into 32 bits, and outputting a (3 k+1)-bit stream by puncturing the first coded bit stream according to a specific mask pattern corresponding to the k value; and generating, by the DSCH encoder, a second coded bit stream by encoding the (10−k) input bits into 32 bits, and outputting a {3*(10−k)+1}-bit stream by puncturing the second coded bit stream according to a specific mask pattern corresponding to the (10−k) value.

Provided may be a method of fabricating nanowires and a method of fabricating a transistor having the same. The method may include: forming a template layer on a substrate, the template layer having a first lateral surface and a second lateral surface facing the first surface; forming pores in the template layer, the pores disposed between the first lateral surface and the second lateral surface in the template layer and having first apertures in the first lateral surface; forming a single-crystalline material layer contacting the first apertures disposed in the first lateral surface of the template layer; forming second apertures connecting pores disposed in the second lateral surface; supplying gaseous crystal growth materials through the second apertures; and forming crystalline nanowires in the pores by crystal growth from the single-crystalline material layer. The nanowires may be made of crystalline materials, e.g., Si or SiGe, and may be formed parallel to the substrate. Higher quality nanowires, whose orientation may be controlled, may be formed. A higher quality transistor may be formed on the substrate by applying a method of fabricating the nanowires.

An apparatus and method for providing subscriber information in a mobile communication system are provided. A database stores registered information containing subscriber information, a scope of persons to view the subscriber information, and an open level for the subscriber information. A wait time information management server stores the subscriber information in the database. Upon request for a call from a calling terminal, the wait time information management server searches for the subscriber information in the database and provides the searched subscriber information according to the open level to an MSC. The MSC sends wait time information based on the subscriber information received from the wait time information management server to the calling terminal.
