Abstract: The present disclosure is related to a long training field (LTF) sequence for 320 MHz band transmission in a wireless local area network system. The main features comprise the steps of: generating a physical protocol data unit (PPDU); and transmitting the PPDU through a 320 MHz band, wherein the PPDU includes an LTF signal and the LTF signal is generated on the basis of an LTF sequence for the 320 MHz band. Therefore, the proposed LTF has improved effects such as increased bandwidth, an improved PHY layer protocol data unit (PPDU) structure, an improved sequence, and use of a hybrid automatic repeat request (HARQ) technique.

Abstract: A base station transmits a radio resource control (RRC) message indicating that a wireless device starts a time alignment timer of a timing advance group (TAG) in response to the RRC message. The base station starts the time alignment timer of the TAG before transmitting an initial medium access control (MAC) timing advance command (TAC) for the TAG and after transmitting the RRC message.

Abstract: Proposed are a method and a device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The PPDU includes a legacy preamble and first and second signal fields. The legacy preamble and the first and second signal fields are generated on the basis of a first phase rotation value. When the broadband corresponds to a 320 MHz band, the first phase rotation value is [1 −1 j j 1 1 j −j j −j −1 −1 −j −j 1 −1].

Abstract: A guard period for switching between uplink and downlink subframes is created by shortening a downlink subframe, i.e., by not transmitting during one or more symbol intervals at the end of the subframe. A grant message includes signaling indicating when a shortened subframe is being transmitted. An example method is implemented in a receiving node configured to receive data from a transmitting node in subframes having a predetermined number of symbol intervals. In an LTE system, this receiving node may be a UE, and the subframes are downlink subframes. This example method includes determining that a received subframe is to be shortened, relative to the predetermined number of symbol intervals and, in response to this determination, disregarding a last part of the received subframe by disregarding one or more symbols at the end of the received subframe when processing the received subframe.

Abstract: Methods and apparatus are described. A station includes a transceiver and a processor, which receive a trigger frame for an uplink (UL) transmission. The trigger frame includes an indication of resource units (RUs) for random access in an upcoming UL high efficiency trigger based packet data convergence protocol data unit and an indication that the trigger frame is a poll for a buffer status report of the STA. The processor and the transceiver transmit a buffer status of the STA using a selected one of the indicated RUs.
