Abstract: Some embodiments are directed to grouping electronic devices into contention groups to reduce uplink Orthogonal Frequency-Division Multiple Access (OFDMA) random access (OFDMA-RA) collisions. An access point may explicitly assign an electronic device to a contention group, or the electronic device may implicitly determine an assignment to the contention group. To explicitly assign a device to a contention group, the access point may randomly assign or assign based on a criteria of the electronic device. Examples of criteria include an association identifier (AID), a traffic type/quality of service (QoS) category, a power saving preference, and an association status. The electronic device may implicitly determine a contention group assignment based on the total number of contention groups. The electronic device may use the explicitly or implicitly assigned contention group number to determine whether the electronic device may contend for a given trigger frame random access (TF-R) frame.

Abstract: A communication device generates a physical layer (PHY) data unit that includes a PHY preamble and one or more PHY midambles. The communication generates the PHY preamble of the PHY data unit to include i) a signal field having a subfield that indicates that the PHY data unit includes one or more PHY midambles, ii) a short training field (STF) for automatic gain control (AGC) training and synchronization at a receiver, and iii) one or more long training fields (LTFs) for determining a channel estimate at the receiver. The communication generates a data payload of the PHY data unit having i) a set of orthogonal frequency division multiplexing (OFDM) symbols, and ii) one or more PHY midambles. Each of the one or more PHY midambles includes one or more LTFs for determining an updated channel estimate. The communication device transmits the PHY data unit via a wireless communication channel.

Abstract: Novel techniques for pooling the available transmit power of a beam across the subcarriers that are or that are scheduled to be in use (and not across all available subcarriers) are disclosed. The scheduled subcarriers may be located in the same or different carriers of a modulation transmitter modulation system, and the pooled transmit power may be allocated or distributed across the scheduled subcarriers of the beam. Modulation symbols or resource elements may be transmitted in accordance with allocated, per-subcarrier power budgets, thereby maximizing the SNIR of signals that are transmitted in the beam via the scheduled subcarriers. Additionally, the allocation of the pooled transmit power to various subcarriers may continuously and/or dynamically vary over time, e.g., based on traffic demands, interference characteristics, etc., as well as based on subsequent scheduling of subcarriers to transmit subsequent modulation symbols or resource elements.

Abstract: The invention generally relates to methods for analyzing stability of an active pharmaceutical agent. In certain aspects, the methods involve obtaining an active pharmaceutical agent, and distributing the active pharmaceutical agent into one or more microdroplets. The one or more microdroplets including the active pharmaceutical agent are then subjected to one or more conditions that force degradation of the active pharmaceutical agent in each of the one or more microdroplets. The one or more microdroplets are then analyzed to determine a ratio of the active pharmaceutical agent to that of a degradation product of the active pharmaceutical agent, thereby analyzing stability of an active pharmaceutical agent.
