摘要： Disclosed herein is a method performed by an access point (AP) in a wireless network to transmit low latency data. The method includes wirelessly receiving a data frame from a first station (STA) during a transmission opportunity (TXOP) of the first STA, responsive to determining that the AP has low latency data to transmit, wirelessly transmitting a block acknowledgement (BA) frame that acknowledges the data frame to the first STA, wherein the BA frame includes an indication that the AP has low latency data to transmit so the first STA should hold its transmission, and wirelessly transmitting a low latency data frame to a second STA following the transmission of the BA frame.

摘要： A method for determining a number of symbols in a data field of a physical layer (PHY) protocol data unit (PPDU) is described. The method includes determining, by a wireless transmitting device, whether aggregation is to be applied to the PPDU; determining, by the wireless transmitting device, whether a PSDU length indication of the data field for the PPDU is greater than zero; selecting, by the wireless transmitting device, a first value in response to determining that (1) aggregation is not to be applied to the PPDU and (2) the PSDU length indication for the PPDU is greater than zero; and calculating, by the wireless transmitting device, the number of symbols in the data field of the PPDU based on the first value, wherein the first value is the PSDU length indication, wherein the first value is provided in a transmission vector (TXVECTOR).

摘要： A voltage-to-current converter circuit comprises an amplifier, a resistor, first and second feedback circuits, and an output circuit. The amplifier is configured to receive a differential input voltage signal. The resistor is coupled between first and second nodes of the amplifier. The first feedback circuit is coupled to a third node of the amplifier, provides feedback to the first and second nodes when the value of the input voltage signal is in a first range, and is turned off otherwise. The second feedback circuit is coupled to a fourth node of the amplifier, provides feedback to the first and second nodes when the value of the input voltage signal is in a second range different from the first range, and is turned off otherwise. The output circuit produces a differential current output signal having a value according to the value of the input voltage signal.

摘要： A wireless communication device in a wireless system may generate a High Efficiency Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (HE PPDU) frame including (i) an Orthogonal Frequency Division Multiplexing (OFDM) symbol including padding bits and (ii) an extension having a non-zero signal strength, and transmit the HE PPDU frame. A High Efficiency signal (HE-SIG) field of the transmitted HE PPDU frame may include an indication for a duration of the extension to avoid ambiguity of the extension. A communication device in a wireless system may receive an HE PPDU frame including (i) an OFDM symbol including padding bits, and (ii) an extension having a non-zero signal strength, and transmit an Acknowledgement frame a predetermined inter-frame space after an end of the HE PPDU frame. An HE-SIG field of the received HE PPDU may include an indication for duration of the extension to avoid ambiguity of the extension.

摘要： To receive data in data field of a PHY Protocol Data Unit (PPDU), wherein the data field includes mid-ambles, a number of mid-ambles and a number of data symbols included in the data field is determined. The number of mid-ambles is determined according to information in an HE-SIG-A field of the PPDU, information in an L-SIG field of the PPDU, and one or more predetermined values prescribed by a standard. The number of data symbols may be determined using the number of the mid-ambles, and the data received according to the number of mid-ambles and the number of data symbols.
