    Abstract: Provided is a method for transmitting paging information in a cellular system. An object of the method is transmitting paging information which can improve applicability of a limited radio resource by variably and flexibly setting up and mapping a transport channel and a physical channel in order to transmit information notifying start of downlink information from a base station to a terminal in a cellular system for packet transmission. The method includes the steps of: forming a paging channel (PCH) in a transport channel corresponding to generation of paging information; setting a paging indication channel (PICH) based on the paging information and forming the paging indication channel in a radio resource of a physical layer; and allocating the paging channel to the radio resource of the physical layer.

    Abstract: A convergence network based on an identifier and a communication method using the same are provided. The convergence network based on the identifier includes an underlying network including a plurality of communication entities and an access router configured to separate IDs and locators of the communication entities; at least one domain network configured in an overlay form using the access router, and configured to have a different identifier based on a communication type or a service type; and a global name server GNS configured to register an identifier for identifying each of a communication entities and a domain network. The communication entities communicate over the at least one domain network using the identifier.

    Abstract: An operation method of a transmitting node in a communication system may comprise:
    generating 2N initial transmission bits by encoding N information bits to be transmitted to a receiving node of the communication system in a polar coding scheme; transmitting, to the receiving node, an initial transmission signal generated by modulating the 2N initial transmission bits; receiving, from the receiving node, a signal indicating that the initial transmission signal is not normally received; interleaving the N information bits through an interleaver to generate N interleaved bits; generating 2N first retransmission bits by encoding the N interleaved bits in the polar coding scheme; and transmitting, to the receiving node, a first retransmission signal generated by modulating the 2N first retransmission bits.

    Abstract: A method for converting source data to a channel-modulated signal having a plurality of pairs of in-phase (I) and quadrature-phase (Q) data in a mobile station, wherein the mobile station uses at least one channel, includes the steps of: a) encoding the source data to generate at least one data part and a control part; b) generating at least one spreading code to be allocated to the channel, wherein each spreading code is selected on the basis of a data rate of the data part and the control part and spreading codes are selected so that two consecutive pairs of the I and Q data are correspondent to two points located on same point or symmetrical with respect to a zero point on a phase domain; and c) spreading the control part and the data part by using the spreading code, to thereby generate the channel-modulated signal.
