Abstract: Certain aspects of the present disclosure provide methods and apparatus for uplink (UL) multiuser multiple-input, multiple-output (MU-MIMO) transmissions in a High Efficiency WLAN (HEW) system. One example method generally includes generating a packet having a preamble portion and transmitting the packet. The preamble portion typically includes a long training field (LTF); a first signal (SIG) field subsequent to the LTF; one or more other LTFs located subsequent to the first SIG field; and at least one second SIG field, wherein all SIG fields in the preamble portion, other than the first SIG field, are subsequent to the one or more other LTFs. Another example method generally includes receiving, from an apparatus, a packet having a preamble portion comprising tone-interleaved LTFs; and performing frequency offset adjustment on the packet based on the tone-interleaved LTFs.

Abstract: Methods, systems, and devices are described for managing wireless communications in a machine-to-machine (M2M) wireless Wide Area Network (WAN). An event is detected that indicates a condition of a forward link in the M2M wireless WAN. A data rate is selected to transmit an acknowledgment (ACK) message. The selection of the data rate is based at least in part on the detected event that indicates the condition of the forward link. The ACK message is transmitted on the forward link in the M2M wireless WAN according to the selected data rate.

Abstract: In some implementations, a method may comprise determining capabilities of UWB initiator and responder devices related to at least one UWB session. The method may also comprise determining a gap duration based at least in part on the capabilities of the UWB initiator and responder devices for performing RF retuning during the at least one UWB session. The method may also comprise sending a configuration to the UWB initiator and/or responder devices, wherein the configuration is indicative of: a first period of time in the at least one UWB session during which a first portion of the UWB RF signals is transmitted using a first carrier frequency, a gap of at least the determined gap duration following the first period of time, and a second period of time, following the gap, during which a second portion of the UWB RF signals is transmitted using a second carrier frequency.

Abstract: This disclosure provides methods, components, devices and systems for 480 and 640 megahertz (MHz) transmission in Wi-Fi. Some aspects more specifically relate to inclusion of a bandwidth field and a bandwidth extension field in a preamble of a physical layer protocol data unit (PPDU) that jointly indicate that the channel bandwidth of the PPDU is a contiguous 480 MHz channel bandwidth or a 640 MHz channel bandwidth. In some aspects, parameters of the PPDU may be defined based on the PPDU occupying a 480 MHz or 640 MHz bandwidth. For example, the parameters may include tone plans, allowed puncturing patterns, signaling of the puncturing plans, signaling of the resource unit allocation, a short training field, a long training field, pilot signal sequences, phase shifts, a segment parser, and/or a spectral mask.

Abstract: This disclosure provides methods, devices and systems for increasing carrier frequencies for wireless communications in wireless local area networks (WLANs). Some implementations more specifically relate to BSS discovery and association techniques that support wireless communications on carrier frequencies above 7 GHz. In some aspects, an access point (AP) may communicate using beamforming on a wireless communication link operating at a carrier frequency above 7 GHZ (the “directional link”) while offloading the BSS discovery and association procedures needed to support such communications onto a wireless communication link operating at a carrier frequency below 7 GHZ (the “anchor link”). In some implementations, the AP may perform a beamforming training operation with a STA over the directional link upon associating with the STA over the anchor link. In such implementations, the AP may communicate with the STA over the directional link using a beam derived from the beamforming training operation.

Abstract: Methods and systems for amplitude shaping encoding and indicating boundaries in bitstreams are described. A transmitting device may insert, into a bitstream to indicate a boundary, a sequence of amplitude bits unassociated with patterns of bit values in a lookup table used for the encoding. A transmitting device may monitor a length of the amplitude bits in a bitstream during the encoding and stop the encoding on information bits at an end of a current data unit responsive to the length reaching a threshold. A transmitting device may monitor the length of the information bits and, for each data unit, determine whether a boundary is reached. Responsive to determining that a boundary is reached, the transmitting device may not include, before the boundary, amplitude bits generated based on the information bits in the data unit, and add padding bits after a last amplitude bit before the boundary.
