Abstract:
A method and apparatus are provided for allocating code resources to ACK/NACK channel indexes, when UEs need ACK/NACK transmission in a wireless communication system in which a predetermined number of orthogonal cover Walsh codes is selected from among available orthogonal cover Walsh codes, at least one subset is formed, having the selected orthogonal cover Walsh codes arranged in an ascending order of cross interference, subsets are selected for use in first and second slots of a subframe, and the orthogonal cover Walsh codes of the subset selected for each slot and ZC sequence cyclic shift values are allocated to the ACK/NACK channel indexes.
Abstract:
An interleaving method in a mobile communication system is provided. The interleaving method includes encoding a plurality of bits to output encoded bits in a sequence, interleaving the encoded bits based on a modulation order to generate interleaved encoded bits comprising consecutive bits having a size based on the modulation order, the consecutive bits corresponding to consecutive bits of the encoded bits, scrambling the interleaved encoded bits with a scrambling code to generate scrambled bits, and modulating the scrambled bits based on the modulation order to output at least one symbol.
Abstract:
An electronic device according to various embodiments of the present invention may comprise: a body which is made of a conductive material and has both ends curvedly extending to be adjacent to each other so as to have a loop shape; a communication module arranged on the body; a feeding line which extends from the communication module and is arranged to cross a gap between both ends of the body; and at least one connection terminal for connecting the feeding line to the body, wherein the body can receive a feeding signal from the communication module through the feeding line, and transmit/receive a wireless signal. The above-mentioned electronic device can be implemented variously according to embodiments.
