Abstract: PURPOSE: An uplink resource allocation method in a wireless communication system is provided to reduce the time consumed in a resource allocating process for transmitting data in an uplink. CONSTITUTION: A UE(User Equipment) constitutes a first message in order to include a preamble. The UE constitutes a first message to adaptively include more resource request information according to the communications state with a BS(Base Station). The UE transmits the first message to the BS(S300). The communications state is determined by considering the information from a group, including channel quality information, with the BS, location information, and downlink receiving signal level information.

Abstract: PURPOSE: A method for preventing collision of tag is provided to recognize a plurality of tag information simultaneously using at least more than two preambles. CONSTITUTION: A reader(100) transmits a new order message to a tag(200). The new order message includes a partial success command and ID information of tags succeeding in reception. The tag analyzes the order message. If the partial success command is included in the command message, the tag extracts ID information of the tag which successfully gets a tag. If the extracted tag ID information is same with the tag ID information, the tag transmits a response message to the reader.

Abstract translation: 目的：提供一种防止标签碰撞的方法，用至少两个以上的前同步码同时识别多个标签信息。 构成：读取器（100）向标签（200）发送新的订单消息。 新的订单消息包括部分成功命令和接收中的标签的ID信息。 标签分析订单消息。 如果命令消息中包含部分成功命令，则标签提取成功获取标签的标签的ID信息。 如果提取的标签ID信息与标签ID信息相同，则标签向读取器发送响应消息。

Abstract: PURPOSE: A method for controlling an uplink access in a wireless communication system is provided to change an access probability sequence, thereby reducing probability between terminals. CONSTITUTION: A terminal generates an access probability sequence(S100). The terminal transmits data based on access probability in the access probability sequence(S200). When the terminal transmits the data within a time slot, the terminal receives a successful result for the data transmission from the base station(S300). The terminal controls access probability used for the data transmission according to the successful result(S400).
