Abstract: The present disclosure describes a method and apparatus for transmit power calibration in a frequency division multiplexed wireless system (100). The method may include receiving (315) an uplink scheduling grant at a user equipment (120), establishing (320) a desired power level based on at least the uplink scheduling grant, and setting (325) hardware power settings based on the desired power level. The method may also include transmitting (330) data in a first subframe at a first power level based on the hardware power settings, measuring (335) the first power level in the first subframe, and determining (340) a difference between the desired power level and the measured first power level. The method may additionally include modifying (345) the hardware power settings based on the difference and transmitting (350) at a second power level based on the modified hardware power settings in a next transmission corresponding to the transmission in the first subframe.

Abstract: A communication system (100), comprising a first communication unit (112) communicating (118) with a second communication unit (122), said first communication unit (112) transmitting to said second communication unit a preamble (516) prior to a message, wherein the preamble is a concatenation of signals, said second communication unit receives and decodes the preamble (516) and compares the received concatenated signals with know pre-determined concatenated signals to determine whether an error has occurred in said preamble (516) or said first message.This enables a system employing the FAUSCH concept to carry more information than a simple request for a channel. For example, it could include the data rate of the required channel. It also allows an extra degree of flexibility when designing the protocols. It allows forward error correction to be applied to the channel. Hence, the receiver can detect and correct some transmission errors.

Abstract translation: 一种通信系统（100），包括与第二通信单元（122）通信（118）的第一通信单元（112），所述第一通信单元（112）在消息之前向所述第二通信单元发送前导码（516） ，其中所述前同步码是信号的级联，所述第二通信单元接收并解码前导码（516），并将所接收的级联信号与已知预定的级联信号进行比较，以确定所述前同步码（516）或所述 第一消息。这使得采用FAUSCH概念的系统能够携带比针对信道的简单请求更多的信息。 例如，它可以包括所需通道的数据速率。 它还允许在设计协议时额外的灵活性。 它允许向通道应用前向纠错。 因此，接收机可以检测和纠正一些传输错误。
