Abstract: 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).

Abstract: In wireless communications, an access point may transmit a first frame to one or more stations. In response to the first frame, the station(s) may transmit a respective second frame to the access point. The access point may generate a beamforming report based on the second frame(s) received by the access point from the station(s). The access point may transmit a third frame(s) that includes the beamforming report to the station(s). The station(s) may generate a respective beamforming matrix based at least on the third frame(s). Other methods, apparatus, and computer-readable media are also disclosed.

Abstract: In wireless communications, an access point may send a trigger frame to multiple stations. The trigger frame's payload may include a first content and a second content, where the first content is associated with a legacy signal field of an uplink frame, and the second content is associated with a non-legacy signal field of the uplink frame. In response to the trigger frame, one or more stations may generate the uplink frame(s) based on the trigger frame and transmit the uplink frame(s) to the access point. The uplink frame(s) may include a legacy signal field and a non-legacy signal field. The legacy field may include a length of the uplink frame(s) that is based on the first content. The non-legacy signal field may include a remaining transmission opportunity (TXOP) duration that is generated based on the second content. Other methods, apparatus, and computer-readable media are also disclosed.

Abstract: A wireless device receives a Multi-User Request-To-Send (MU-RTS) frame, descrambles first scrambled data in the MU-RTS frame using a first scrambling sequence, generates second scrambled data using a second scrambling sequence, and transmits a Clear-to-Send (CTS) frame including the second scrambled data in response to receiving the MU-RTS frame. The second scrambling sequence is an N-bit left cyclic shift of the first scrambling sequence. Another wireless device generates first scrambled data using a first scrambling sequence and transmits an MU-RTS frame including the first scrambled data. The wireless device receives a CTS frame transmitted in response to the MU-RTS frame, and descrambles second scrambled data in the CTS frame using a second scrambling sequence. The second scrambling sequence is an N-bit left cyclic shift of the first scrambling sequence. In either device, N may be 7, and lengths of the first and second scrambling sequences may be 127 bits.

Abstract: A wireless device receives a frame including a first Resource Unit (RU) allocation subfield including resource information for a first frequency area and indicating a first number of user fields in a first channel that correspond to the first frequency area, and a second RU allocation subfield including resource information for a second frequency area and indicating of a second number of user fields in a second channel that correspond to the second frequency area. When the first and second frequency areas are a same RU, the wireless device determines, using both the RU allocation subfields, a number of users allocated to the same RU. A wireless device generates and transmits a frame including first and second RU allocation subfields as described above. When the first and second frequency area are a same RU, both the RU allocation subfields indicates a number of users allocated to the same RU.

Abstract: In wireless communications, an access point may send a trigger frame to multiple stations. The trigger frame may include a carrier sense required subfield that can be set to a first state or a second state. The carrier sense required subfield indicates whether the stations are required to consider a status of carrier sensing in determining whether or not to respond to the trigger frame. A station that receives a trigger frame having the carrier sense required. subfield set to the first state may send a response at a predetermined time interval without performing a carrier sense operation. A station that receives a trigger frame having the carrier sense required subfield set to the second state may determine whether to send a response based on performing a carrier sense operation.

Abstract: In wireless communications for multi-users, an access point may generate a first frame for allocating resources to a plurality of stations. The first frame may contain an indication as to whether a station(s) is allocated at least one of a set of resource units (RUs) of a plurality of RUs, such as a center 26-tone RU. The set of resource units may be based on a channel bandwidth of the wireless communications. The indication may be contained in a common block field of signal fields, such as a common block field of high efficiency (HE) signal content channel(s) of an HE signal field. The station(s) may receive the first frame and determine whether the one of the set of RUs is allocated. The station(s) may transmit a second frame to the access point based on resource allocation information in the first frame. Other methods, apparatus, and computer-readable media are also disclosed.

Abstract: In wireless communications for multi-users, an access point may transmit a first trigger frame to one or more stations. The first trigger frame may be for scheduling a first uplink multi-user transmission and may indicate a plurality of resources for indicating existence of data to be sent to the access point. The station(s) may process the first trigger frame received from the access point. In response to the first trigger frame, the station(s) may generate and transmit a respective first uplink frame to the access point. In some cases, the first uplink frame(s) from the station(s) does not have a data field and does have a signal indicating existence of data to be sent from the station(s) to the access point. The signal may be sent using a resource(s) of the plurality of resources. Other methods, apparatus, and computer-readable media are also disclosed.

Abstract: 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.

Abstract: 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.
