Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to Wi-Fi systems including frame extensions in transmission frames. Lengths of frame extensions may be determined based on transmission bandwidths and transmission data rates of the frames. Lengths of frame extensions may also be determined based on an amount of useful data in a final symbol of the frame. An access point (AP) may determine frame extension lengths for use in transmitting to stations (STAs) based on reception capabilities of the STAs. An AP may determine frame extension lengths for STAs to use in transmitting frames.

Abstract: Systems and methods for wireless communications are disclosed. More particularly, aspects generally relate to techniques for indicating a minimum and maximum channel bandwidth in a frame (e.g., short frame). One or more bits in the frame, for example a management frame, may indicate both minimum and maximum bandwidths for communicating in the network. According to aspects, a wireless terminal may determine the minimum and maximum bandwidths for communicating in the network based on a mapping of different values of the one or more bits to combinations of minimum and maximum bandwidths. While any field in the frame may indicate the minimum and maximum bandwidth, according to aspects, the Basic Service Set (BSS) bandwidth (BW) field may be used for the indication.

Abstract: Methods, systems, and devices are described for managing wireless communications in a machine-to-machine (M2M) wireless Wide Area Network (WAN). A packet is decoded and demodulated by an M2M device that is received during a time slot of a physical layer forward link frame in the M2M wireless WAN. The packet is transmitted by a base station. The M2M device enters a sleep state before a physical layer acknowledgment (ACK) message is transmitted to the base station to indicate receipt of the packet.

Abstract: This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to short training field (STF) designs and signaling that support distributed transmissions. A transmitting device that transmits data on a distributed resource unit (dRU) may transmit an STF sequence over a spreading bandwidth of the dRU according to an existing STF tone plan. Each STA allocated a dRU for transmission in a trigger-based (TB) physical layer convergence protocol (PLCP) protocol data unit (PPDU) maps its STF sequence to one or more spatial streams and may apply one or more global cyclic shift delays (CSDs) to the STF sequence mapped to the one or more spatial streams, respectively. As such, different global CSDs may be assigned to different STAs so that each STA transmits its STF sequence with different amounts of delay.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for priority access on a shared wireless channel. A priority station (STA), an access point (AP), or a network operator may activate a priority access service. The priority access service provides priority access to authorize priority STAs by allowing them to use more aggressive contention parameters for contention-based access of the wireless channel as compared to other STAs. In some implementations, non-priority STAs may be configured with weakened contention parameters to increase or ensure the likelihood that a priority STA will win contention for access to the wireless channel.

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 packet designs and numerologies that support wireless communications on carrier frequencies above 7 GHz. In some aspects, a wireless communication device may up-clock a physical layer (PHY) convergence protocol (PLCP) protocol data unit (PPDU) for transmission on carrier frequencies above 7 GHz, where the PPDU conforms to an existing PPDU format associated with carrier frequencies below 7 GHz. As used herein, the term “up-clocking” refers to increasing the frequency of a clock signal used to convert the PPDU between the frequency domain and the time domain. In some aspects, the up-clocking may result in a subcarrier spacing (SCS) greater than or equal to 1.2 MHz, where the SCS represents a spacing between the subcarriers on which a PHY preamble of the PPDU is modulated.
