摘要： The present invention proposes a receiver (1) and method for decoding data packets. A receiving unit (5) of the receiver (1) receives a data packet P1, which contains a MAC header. A soft decoder (3) of the receiver (1) decodes the data packet P1 to obtain soft values of the data packet P1, and an error checking module (2) of the receiver performs a cyclic redundancy check, CRC, on the data packet P1. If the CRC on the data packet P1 fails, a hard decoder (4) of the receiver (1) performs a first hard decision on the soft values of the data packet P1 corresponding to the MAC header of the data packet P1, and a controller (8) of the receiver (1) determines based on the result of the first hard decision, whether soft values of a previous transmission of the data packet P are stored in a memory (6) of the receiver (1), and combines said stored soft values with the soft values of the data packet P1 to obtain combined soft values. Finally, the error checking module (2) performs a CRC based on the combined soft values.
摘要翻译：本发明提出了一种用于对数据分组进行解码的接收机（1）和方法。接收机（1）的接收单元（5）接收包含MAC报头的数据分组P1。接收机（1）的软解码器（3）对数据分组P1进行解码以获得数据分组P1的软值，并且接收机的错误检查模块（2）在数据分组上执行循环冗余校验CRC P1。如果数据分组P1上的CRC失败，则接收机（1）的硬解码器（4）对与数据分组P1的MAC头对应的数据分组P1的软值执行第一硬判决，控制器接收机（1）的接收机（8）基于第一硬判决的结果确定数据分组P的先前发送的软值是否被存储在接收机（1）的存储器（6）中，并将所述存储软值与数据包P1的软值，以获得组合的软值。最后，错误检查模块（2）基于组合的软值执行CRC。

摘要： The invention relates to a mechanism that allows the simultaneous transmissions in different parts of the available spectrum of an OFDM system, e.g. WiFi. An access point can thereby enable simultaneous transmissions from/to multiple client stations on different parts of the spectrum. This is achieved by implementing OFDMA that is transparent to the communicating stations by using multiple station identifiers, each of which is associated to a different part of the available bandwidth/spectrum in order to support simultaneous transmissions on the different parts of the bandwidth/spectrum.
摘要翻译：本发明涉及允许在OFDM系统的可用频谱的不同部分中的同时传输的机制，例如，无线上网。因此，接入点可以在频谱的不同部分上实现与多个客户站的同时传输。这通过使用多个站标识符来实现对通信站透明的OFDMA来实现，每个站标识符与可用带宽/频谱的不同部分相关联，以便支持带宽/频谱的不同部分上的同时传输。
