Abstract: Payload transmission of multiple stations on a single resource unit may be performed. New and/or updated signaling may be introduced to enable a transmitter, e.g., an access point (AP), to include information/signaling in the preamble or in other frames. A receiver (e.g., a wireless station) that receives this information/signaling may accordingly determine in which RU it should decode to receive its allocated data or payload, allowing multiple receivers or STAs to share a single resource unit (RU). The new/updated signaling may include modified hybrid downlink multiuser signaling in Ultra High Reliability Signal (UHR-SIG), a group association identifier (gAID), a predefined special AID corresponding to an RU with use of a Bloom filter, multiple predefined special AIDs each corresponding to a non-overlapping group of wireless stations, and/or signaling announcing time sharing of single RUs.

Abstract: Multiuser (MU) Multi-TID (multi-traffic-identifier) transmission may be enabled in a resource unit (RU). To transmit an urgent payload as soon as possible, the urgent payload may be injected/included into the ongoing MU physical protocol data unit (MU PPDU), if possible. This may be accomplished by indicating to the latency-sensitive wireless station (STA) the ID of a companion (or buddy) station that has an assigned resource unit (RU) on which the STA may expect to receive the urgent payload, also referred to as the “overloaded RU.” Alternatively, an extra user field in the preamble of the MU PPDU may be used to indicate to the STA its station ID as well as the location of the overloaded RU. A receiver operating on an A-MPDU may select the RU it receives, and may identify (or determine) a wrong transmission based on the transmitter address.

Abstract: A method for preparing isophorone diisocyanate by (1) reacting isophorone with hydrogen cyanide in the presence of a catalyst to obtain isophorone nitrile; (2) reacting the isophorone nitrile obtained in step (1) with ammonia gas and hydrogen in the presence of a catalyst to obtain isophorone diamine; and (3) subjecting the isophorone diamine to a phosgenation reaction to obtain the isophorone diisocyanate, wherein the content of impurities containing a secondary amine group in the isophorone diamine that undergoes the phosgenation reaction in step (3) is ?0.5 wt.
