Abstract: Embodiments described herein provides a system for detecting data received in a low power low rate (LPMR) data frame format. The system includes a receiver and control circuitry. The receiver is configured to receive a data frame comprising an LPLR preamble portion and an LPLR data portion following the LPLR preamble portion. The LPLR preamble portion and the LPLR data portion occupy a bandwidth that is less than an allowed bandwidth. The control circuitry is configured to determine a mode of the data frame based on whether the data frame has an additional portion, and detect data field in the LPLR preamble portion from the data frame based on the mode of the data frame.

The feedback indication field is generated to include a first value that indicates the MPDU delimiter includes the feedback content field rather than an MPDU length field corresponding to a second value of the feedback indication field. The feedback content field is generated to include feedback information such as acknowledgement information regarding a communication frame previously transmitted by a second communication device, or control, management, and/or status information regarding the first communication device that was previously requested by the second communication device. The first communication device then transmits a packet that includes the MPDU delimiter to the second communication device.

Abstract: A communication device generates a first data unit that spans a first bandwidth, and transmits the first data unit during a transmit opportunity (TXOP) to at least one other communication device. The communication device subsequently determines, based on respective values of TXOP duration fields included in respective physical layer (PHY) preambles of one or more data units previously transmitted during the TXOP, whether a second bandwidth of a second data unit to be transmitted by the communication device during the TXOP can be greater than the first bandwidth of the first data unit. In response to determining that the second bandwidth of the second data unit can be greater than the first bandwidth of the first data unit, the communication device generates the second data unit to span the second bandwidth greater than the first bandwidth, and transmits the second data unit during the TXOP.

Abstract: A system includes a host and a display. The host includes a programmable logic device (PIP), a baseboard management controller (BMC) and a switch. The PLD performs a power-on procedure based on a power-on sequence code, generates variable character information in the power-on procedure, and fills the variable character information into a variable field in a preset log text file to result in an updated log text file. When it is determined that the power-on procedure is not normally completed, the PLD controls the switch to switch to a debug mode, and transmits a video signal containing debug information corresponding to the updated log text file to the switch so that the video signal is outputted to the display.
