    Abstract: Métodos e equipamento terminal para transmitir informações de controle de uplink e recebê-las em estação de base terminal. Quando uma pluralidade de terminais compartilha os mesmos recursos num sistema de comunicações sem fio e quando controlam informações tais como informações de recebimento/confirmação negativa (ack/nak) ou são transmitidas informações de programação, é exigido realizar eficientemente um método de multiplexação de divisão de código (cdm) para distinguir a pluralidade determinais. Em particular, é necessário desenvolver um método pelo qual possa ser selecionada e usada uma seqúéneia de códigos de cdm de acordo com cada condição de célula. É proporcionado um método deformação de um sinal num sistema de comunicações sem fio em que uma pluralidade de terminais comumente compartilha recursos de frequência e de tempo. O método inclui as operações de recebimento de informações de condição numa célula; selecionar uma de uma pluralidade de seqúências ortogonais de domínio de tempo tendo comprimentos diferentes, de acordo com as informações de condição; e alocar a seqüência ortogonal de domínio de tempo selecionada para um bloco de símbolos de sinal de controle.

    Abstract: When a plurality of terminals share the same resources in a wireless communication system, and when control information such as acknowledgement/negative acknowledgement (ACK/NAK) information or scheduling information is transmitted, a method of efficiently performing code division multiplexing (CDM) is required to distinguish the plurality of terminals. In particular, it is necessary to develop a method by which a code sequence of CDM can be selected and used according to each cell condition. Provided is a method of forming a signal in a wireless communication system in which a plurality of terminals commonly share frequency and time resources. The method includes the operations of receiving condition information in a cell; selecting one of a plurality of time domain orthogonal sequences having different lengths, according to the condition information; and allocating the selected time domain orthogonal sequence to a control signal symbol block.

    Abstract: Provided is method of forming a signal in a wireless communication system in which a plurality of terminals commonly use a resource in the time domain and the frequency domain. The method includes multiplying a signal to be transmitted by a frequency domain orthogonal code symbol corresponding to a first cyclic shift index in a first slot to be transmitted to a base station, wherein the multiplying is performed by a first terminal and a second terminal; and multiplying information to be transmitted by a frequency domain orthogonal code symbol corresponding to a second cyclic index that is different from the first cyclic index of the first slot to be transmitted to the base station, in a second slot, wherein the multiplying is performed by the first terminal and the second terminal.
