在通信系统中标识发往用户的信息的方法以及通信系统
摘要：
本发明涉及在一个通信系统中用以标识发往用户的信息的方法，还涉及一个通信系统，该通信系统包括至少一部发射机(120)以及至少一部接收机(UE)，在该通信系统中，发射机被安排在共享信道(312)上发送具有训练序列(300)的数据分组(330A到330D)，在该信道上，有两部或多部接收机被安排为接收所述数据分组，并且接收机被安排根据训练序列来产生信道估计。通信系统被安排为向待发往不同的接收机或接收机组的数据分组提供不同的训练序列，接收机被安排为将信道估计值跟用以衡量信道质量的阈值进行比较，当信道估计值超过阈值时，接收机被安排为对数据分组进行进一步的处理，而当信道估计值低于阈值时，接收机被安排为忽略该数据分组。
摘要（英）：

The invention relates to a method of identifying information addressed to a user in a communication system, and to a communication system comprising at least one transmitter (120) and at least one receiver (UE), in which communication system the transmitter is arranged to transmit on a shared channel (312) data packets (330A to 330D) provided with a training sequence (300), on which channel two or more receivers are arranged to receive said data packets, and the receiver is arranged to generate a channel estimate on the basis of the training sequence. The communication system is arranged to provide the data packets addressed to different receivers or receiver groups with different training sequences, the receiver is arranged to identify and further process the data packets addressed to the receiver and whose training sequence the receiver identifies, and the receiver is arranged to ignore the data packets whose training sequence the receiver does not identify.
