Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for partial bandwidth feedback based on punctured sounding. Punctured sounding is used by a transmitting device that omits portions of a channel bandwidth based on a puncturing pattern. The puncturing pattern may be based on an exclusion bandwidth zone to avoid transmissions on portions of channels that may interfere with an incumbent system transmission. The puncturing pattern may be indicated in a null data packet announcement (NDPA) to inform the receiving device that a subsequent NDP will be punctured. The receiving device may determine the feedback by measuring the portions of the NDP that are not punctured. Beamforming may be enhanced by using punctured sounding between two beamforming endpoints.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for multiplexing clients in a wireless communication network. In one aspect, a wireless station (STA) receives a preamble including a first wireless local area network (WLAN) signaling field from an access point (AP). The first WLAN signaling field includes first and second indications of first and second channel bandwidths. The first channel bandwidth includes a first set of subchannels and used by the AP to communicate with a first set of stations. The second channel bandwidth may include the first set of subchannels and a second set of subchannels and used by the AP to communicate with a second set of stations. The STA may identify a location of at least one second WLAN signaling field for the STA based on the first and second indications of the first and second channel bandwidths.

Abstract: Methods and apparatuses are disclosed for communicating over a wireless communication network. One such apparatus can include a memory that stores instructions and a processor coupled with the memory. The processor and the memory can be configured to identify a transmission mode for a transmission of a signal; select a tone plan for transmission of the signal within a 320 MHz total channel bandwidth or a 240 MHz total channel bandwidth, where the tone plan includes a 256 point tone plan, 512 point tone plan, 1024 point tone plane, 2048 point tone plan, 4096 point tone plan, or some combination thereof, and where the tone plan is selected based at least in part on the transmission mode; generate the signal according to the tone plan; and transmit the signal over the 320 MHz total channel bandwidth or over the 240 MHz total channel bandwidth.

Abstract: Techniques are described for wireless communication. A method for wireless communication at an access point may include identifying a number of stations to receive data from the access point, and generating a downlink frame to transmit the data to the identified number of stations. The downlink frame may include a first signaling field (e.g., a wireless local area network (WLAN) signaling field) directed to the identified number of stations. The first signaling field may include a first segment and a second segment. The first segment may include information common to each of the identified number of stations. The second segment may include at least one information block. Each information block may be separately encoded for each of the identified number of stations. The method may also include transmitting the downlink frame to the identified number of stations.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may use wireless local area network (WLAN) signaling fields in a multiple user transmission preamble to communicate with a number of stations greater than a threshold. For example, the AP may determine that the number of stations is greater than the threshold and generate a compression indicator and an indication of the number of stations to include in a first signaling field. The AP may then generate a spatial configuration indicator in a second signaling field based on the number of stations and transmit the first and second signaling fields in a preamble of the multiple user transmission. Upon receiving the preamble, a station may identify the compression indicator and number of stations, and the spatial configuration indicator in the first and second signaling fields, and decode the multiple user transmission using a determined spatial decoding scheme.
