METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING UPLINK CONTROL CHANNELS IN CELLULAR COMMUNICATION SYSTEMS

摘要

Disclose the transceiver apparatus and method of the ACK/naekeu in a mobile radio communications system. Method can be mapped to cyclic shift value and orthogonal walsh covering to include in ACK/NACK channel indexs cyclic shift value coding be, for sending the sequence of processing, for receiving the ACK/NACK information of the data from base station, to the mapping relations of base portion, the covering of the step of orthogonal walsh of the cyclic shift value and walsh codes and orthogonal lid, the cyclic shift value of acquisition and acquisition that are wherein mapped by using ACK/NACK channel indexs and acquisition is encoded, because terminal is the following steps are included: ACK/NACK information of the transmission for received data. Mapping relations, the orthogonal lid walsh codes of first covering third of the cover orthogonal Walsh code and orthogonal Walsh code, two ACK/NACK channel indexs of the cyclic shift value transmission of the even number of cyclic shift value are used for each figure, second orthogonal code is a Walsh lid, one cyclic shift value suitable for being mapped to odd number is transmitted using a cyclic shift value of the ACK/NACK on channel index, first orthogonal code is a Walsh lid [+1+1+1+1], second orthogonal code is a Walsh lid [+1-1+1-1], the orthogonal lid Walsh code [+1-1-1+1] of third is. ;SC-FDMA, ACK/NACK, Zadoff- Zhu, orthogonal lid, Walsh
