摘要： Provided is a base wireless communication terminal. The base wireless communication terminal includes a transceiver and a processor. The processor is configured to transmit a mixed Physical Layer Protocol Data Unit (PPDU) including both data for a Long Range (LR) wireless communication terminal and data for a non-LR wireless communication terminal to the LR wireless communication terminal and the non-LR wireless communication terminal using the transceiver. The LR PPDU including only the data for the LR wireless communication terminal has a narrower bandwidth than a bandwidth of the non-LR PPDU including only the data for the non-LR wireless communication terminal.

摘要： Mechanisms may be used for aggregating acknowledgement (ACK), block ACK (BA) and/or short packets transmissions for multi-user (MU) wireless communication systems. Aggregation mechanisms may be used for uplink (UL) and/or downlink (DL) orthogonal frequency division multiple access (OFDMA), and/or UL/DL multiple-user multiple input multiple output (MU-MIMO) transmissions, for example. Multi-user short packets may be aggregated and/or simultaneously transmitted for DL, UL, or peer-to-peer (P2P) transmissions.

摘要： A communication device selects a frequency bandwidth via which a physical layer (PHY) protocol data unit (PPDU) will be transmitted in a vehicular communication network, and generates, the PPDU i) according to a downclocking ratio of 1/2, and ii) based on an orthogonal frequency division multiplexing (OFDM) numerology defined by an IEEE 802.11ac Standard. In response to the selected frequency bandwidth being 10 MHz, the PPDU is generated according to the downclocking ratio of 1/2 and based on the OFDM numerology defined by the IEEE 802.11ac Standard for 20 MHz PPDUs. In response to the selected frequency bandwidth being 20 MHz, the PPDU is generated according to the downclocking ratio of 1/2 and based on the OFDM numerology defined by the IEEE 802.11ac Standard for 40 MHz PPDUs.

摘要： A method for transmitting a physical layer protocol data unit (PPDU) and a device using the same are provided. The device receives a trigger frame for requesting a transmission of a high efficiency (HE) trigger-based (TB) PPDU and transmits the HE TB PPDU. A duration of the HE TB PPDU is calculated based on a duration of the trigger frame.

摘要： Techniques pertaining to preamble designs for next-generation wireless local area networks (WLANs) in 60 GHz band are described. A first apparatus communicates in a 60 GHz band wirelessly with a second apparatus by transmitting a first physical-layer protocol data unit (PPDU) to the second apparatus and/or receiving a second PPDU from the second apparatus. Each of the first PPDU and the second PPDU and a respective preamble thereof are either with or without at least partial backward compatibility with one or more preexisting PPDU formats and preambles.
