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 known predetermined 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: 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 (320), at a user equipment (120), a signal from a base station (130) in a frequency division multiplexed wireless system and mapping (330), in response to receiving the signal from the base station, a power control calibration region to an uplink symbol in a subframe to establish a mapped uplink symbol using predetermined criteria. The method can also include calibrating (350) a transmit power based on transmission in the calibration region and transmitting (360) data at the calibrated transmit power on at least one other symbol following the mapped uplink symbol.
