摘要： A wireless device transmits a frame by determining a plurality of Resource Units (RUs) of the frame, providing pilots in a first RU of the frame at a first set of positions, providing pilots in a second RU of the frame at a second set of positions, and transmitting the frame. The first set of positions is different from the second set of positions. A wireless device receives a frame including an RU including pilots and processes the pilots. When an RU for the data symbol includes an odd-numbered lowest subcarrier, the pilots are included at a first set of positions in the resource unit. When the RU includes an even-numbered lowest subcarrier, the pilots are included at a second set of positions in the resource unit. The second set of positions is different from the first set of positions.

摘要： Systems, methods, and devices are provided for protecting a multiuser (MU) transmission between an access point and a plurality of wireless stations. The access point may transmit a frame that is addressed to multiple stations in a wireless network. Each of the stations addressed by the frame may respond with an identical clear-to-send frame. In some instances, the clear-to-send frames transmitted by each wireless station may utilize the same scrambling code utilized by the frame transmitted by the access point, use the same modulation and coding scheme, and/or occupy the same frequency bands such that the multiple clear-to-send frames are combined in the air and detected as a single frame by the access point. In some instances, the access point may thereafter transmit an uplink reference frame to trigger the wireless stations to transmit an uplink data request frame to the access point.

摘要： A wireless device initiates an Up-Link Trigger Based Multi-User communication by transmitting a trigger frame. The communication may be an Orthogonal Frequency Division Multiple Access communication. The trigger frame includes allocation information for resources of the communication, including Random Access (RA) allocation information. The trigger frame may also include a padding field after the allocation information. A length of the padding field is determined according to an amount of time needed for a station receiving the trigger frame to process the RA allocation information. The amount of time may correspond to a time between an end of a last RA allocation information and an end of a Physical layer Protocol Data Unit including the trigger frame. The amount of time may be determined according to a maximum processing time of stations associated with the wireless device, or may be determined according to a predetermined interval.

摘要： A multi-user uplink transmission is performed by analyzing, by a first wireless station, a spatial reuse field in a first frame, and generating, by the first wireless station, a second frame, wherein the second frame includes a spatial reuse field that is generated based on the spatial reuse field of the first frame. The first frame and the second frame are within the same transmission opportunity (TXOP) and the first frame is transmitted prior to the second frame during the TXOP.

摘要： A wireless device determines a Basic Service Set (BSS) associated with a wireless transmitter by receiving a first frame, determining an address of the first frame, receiving a second frame, and determining, using the address of the first frame, a property of the second frame. Determining the property of the second frame may include determining whether the second frame is intra-BSS frame or an inter-BSS frame. Determining the property of the second frame may be performed by comparing an address of the second frame with the address of the first frame, and the second frame determined to be an intra-BSS frame when the address of the first frame matches the address of the second frame, and determined to be an inter-BSS frame otherwise. The address of the first frame may be a transmitter address (TA).

摘要： A wireless devices communicates a transmission capability by determining a number of active transmits chains of the wireless device, determining a maximum number of space-time streams according to the number of active transmit chains, providing a frame with an indication of the maximum number of space-time streams, and transmitting the frame. The wireless devices may provide the indication of the maximum number of space-time streams in an Operating Mode field of High Efficiency Aggregate Control field of the frame. The maximum number of space-time streams may be a maximum number of space-time streams that may be used by the wireless device to respond to a Trigger frame.

摘要： The embodiments provide a method implemented by a network device in a wireless local area network (WLAN) to provide a deferred clear channel assessment (CCA) from a physical layer to an upper layer within the network device. The deferred CCA enables the upper layer to make a final decision on the state of a wireless medium. The method identifies at least one condition on a wireless medium where an upper layer decision is required to determine a state of the wireless medium, and passes on requisite data to the upper layer to enable a decision on the state of the wireless medium. The deferred CCA process supports more complex CCA processes that may rely on information available in an upper layer.

摘要： A transmitting device may perform mid-packet detection (MPD) in a wireless channel by receiving a signal from the wireless channel, detecting first symbols having a first symbol duration in the signal during a first detection window, and detecting second symbols having a second symbol duration in the signal during a second detection window. The first and second symbol durations, excluding CPs, may be 3.2 and 12.8 microseconds respectively. A transmitting device may perform MPD in a wireless channel by receiving a signal from the channel, performing an MPD of symbols in the signal, producing first and second comparison result by comparing an output of the MDP to respective first and second thresholds, and determine whether to transmit a frame using the first comparison result and the second comparison result.

摘要： An Access Point (AP) performs a Multi-User (MU) transmission by allocating a plurality of resources of an Up-Link (UL) MU transmission to a first plurality of stations, and by transmitting, using one or more 20 MHz channels, a Down-Link (DL) PHY Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU). The DL PPDU includes trigger information. The trigger information solicits the first plurality of stations to participate in the UL MU transmission using the allocated resources. All of the allocated resources may be in the one or more 20 MHz channels of the DL PPDU. The allocated resources may include at least one resource in each of the one or more 20 MHz channels of the DL PPDU.
