摘要： A method of generating packets for transmission in a wireless communication system. The method comprises generating a data packet and generating a null data packet. Generating the data packet includes generating a data packet signal (SIG) field including a first data packet SIG subfield indicating a first physical layer (PHY) parameter to a receiving device. Generating the data packet also includes generating a data field. Furthermore, generating the null data packet includes generating a null data packet SIG field. The null data packet SIG field includes a first null data packet SIG subfield indicating a second PHY parameter to a receiving device. The data packet SIG field excludes any SIG subfield indicating the second PHY parameter to a receiving device, and (ii) the null data packet SIG field excludes any SIG subfield indicating the first PHY parameter to a receiving device.

摘要： An access point, AP, device determines a set of basic service set identifiers, BSSIDs. Each BSSID includes a same group of most significant bits (MSBs) and a different group ofnleast significant bits, LSBs. The AP device assigns respective BSSIDs from the set of BSSIDs to multiple virtual APs, and designates one of the assigned BSSIDs as a reference BSSID that corresponds to a transmitter address, TA (510) for frames intended for client stations associated with more than one virtual AP. The AP device generates and transmits a management frame (500) that includes i) a header with a TA field set to one of the assigned BSSIDs (510), and ii) a frame body with a plurality of fields that includes a) a first field (568) set to n, and b) a second field (570) set to the n LSBs of the reference BSSID. The TA field, the first field, and the second field in the management frame indicate the reference BSSID to a client station that receives the management frame.

摘要： A first communication device configured is for communication with one or more second communication devices over a communication channel. The first communication device generates a first bandwidth indication of a first bandwidth of a first channel segment of the communication channel, and generates a second bandwidth indication, separate from the first bandwidth indication, of a second bandwidth of a second channel segment of the communication channel. The first channel segment does not overlap in frequency with the second channel segment. The first communication device generates one or more media access control protocol (MAC) data units to include the first bandwidth indication and the second bandwidth indication, and transmits the one or more MAC data units to the one or more second communication devices to indicate the first bandwidth of the first channel segment and the second bandwidth of the second channel segment to the one or more second communication devices.

摘要： A first communication device transmits a first packet that includes a wakeup request packet configured to prompt a wakeup radio at a second communication device to prompt a network interface device of the second communication device to transition from a low power state to an active state. The first communication device measures a delay period after an end of transmission of the first packet. The delay period corresponds to a time required for the network interface device of the second communication device to transition from the low power state to the active state. After at least the delay period, the first communication device transmits the second packet.

摘要： Systems, apparatuses and methods described herein provide a method for padding a signal extension of orthogonal frequency-division multiplexing (OFDM) symbols. A transceiver may obtain a plurality of data symbols for transmission, and determine that a number of information bits for a last symbol of the plurality of data symbols is not an integer value. A special padding rule may be applied to add padding bits to the last symbol. A number of coded bits for the last symbol may be determined when the number of information bits for the last symbol has changed, and the plurality of data symbols for data transmission may be encoded based on the determined number of coded bits for the last symbol.
