    • The present invention relates to a method of validating the authenticity of a ticket comprising a unique ticket identifier generated at an issuing terminal in accordance with a confidential algorithm. The unique ticket identifier comprises ticket verification information combined with extraneous information. The method comprises the steps of: receiving one or more identification variable values expressed with respect to a first coordinate measurement domain, the one or more identification variable values enabling the location of the ticket verification information within the unique ticket identifier to be determined; using a coordinate transform function configured to map coordinate values from the first coordinate measurement domain to a second coordinate measurement domain to calculate one or more values of the one or more received identification variable values with respect to the second coordinate measurement domain; extracting the verification information from the unique ticket identifier on the basis of the calculated identification variable values; and verifying the authenticity of the ticket on the basis of the extracted verification information. The invention also relates to a terminal for issuing a ticket comprising a unique ticket identifier and a terminal for verifying the authenticity of a ticket comprising a unique ticket identifier in accordance with the afore described method.
    • 本发明涉及一种验证票据的真实性的方法,该方法包括根据机密算法在发行终端产生的唯一票据标识符。 唯一的机票标识符包括与无关信息相结合的票证验证信息。 该方法包括以下步骤:接收关于第一坐标测量域表示的一个或多个识别变量值,使得能够确定唯一票标识符内的票证验证信息的位置的一个或多个识别变量值; 使用坐标变换函数,被配置为将坐标值从第一坐标测量域映射到第二坐标测量域,以计算相对于第二坐标测量域的一个或多个接收的识别变量值的一个或多个值; 基于所计算的识别变量值,从唯一的票标识符提取验证信息; 以及基于提取的验证信息来验证机票的真实性。 本发明还涉及一种用于发行票据的终端,该终端包括独特的票证标识符和用于根据前述方法验证包含唯一票据标识符的票证的真实性的终端。

    • A method in a mobile communication terminal (24) includes receiving a Multi-User Multiple-Input Multiple-Output (MU-MIMO) signal, which includes at least a precoded transmission that is addressed to the terminal and which includes one or more Demodulation Reference Signals (DM-RS). Control information, which indicates one or more scrambling sequences and one or more orthogonalization sequences used in producing the DM-RS, is received in the mobile communication terminal. The control information is provided in a format that does not permit signaling of every possible scrambling sequence and orthogonalization sequence selection. The control information is interpreted in the mobile communication terminal so as to identify the scrambling sequences and orthogonalization sequences used in producing the DM-RS, and the DM-RS are demodulated using the identified scrambling sequences and orthogonalization sequences.
    • 移动通信终端(24)中的方法包括:接收多用户多输入多输出(MU-MIMO)信号,所述多用户多输入多输出(MU-MIMO)信号至少包括寻址到终端的预编码传输,并且包括一个或多个解调参考 信号(DM-RS)。 在移动通信终端中接收控制信息,该信息指示在生成DM-RS中使用的一个或多个加扰序列和一个或多个正交化序列。 以不允许每个可能的扰频序列和正交化序列选择的信令的格式提供控制信息。 在移动通信终端中解释控制信息,以识别在制作DM-RS中使用的加扰序列和正交化序列,并且使用所识别的加扰序列和正交序列解调DM-RS。
