    Abstract: A method and apparatus for transmitting and receiving a frame including a partial association ID (PAID) in a wireless LAN (WLAN) system are disclosed. A method for receiving a frame at a station (STA) from an access point (AP) of a wireless communication system including: determining whether a value of a partial association ID (Partial AID) of the frame is calculated on the basis of an association ID (AID) allocated to the STA by the AP and a basic service set ID (BSSID) of the AP; and decoding the frame, if the value of the partial AID of the frame is calculated on the basis of the AID allocated to the STA and the BSSID of the AP, wherein the AID is allocated such that the partial AID value calculated on the basis of the AID allocated to the STA and the BSSID of the AP is not identical to a first PAID value calculated by applying a modulo operation to a specific value obtained by converting values ranging from a 40th bit position to a 48th bit position from among 48 bit positions of the BSSID of the AP into a decimal number.

    Abstract: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method in which a terminal transmits control information in a wireless communication system, and to an apparatus for the method, wherein the method comprises the following steps: spreading a control information block corresponding to one single carrier frequency division multiplexing (SC-FDMA) symbol, such that the spread control information blocks correspond to a plurality of first SC-FDMA symbols; performing a discrete Fourier transform (DFT) precoding process on the spread control information blocks on an SC-FDMA symbol basis; transmitting, in the plurality of first SC-FDMA symbols in a subframe, the DFT precoded control information blocks; and transmitting, in a plurality of second SC-FDMA symbols in the subframe, a reference signal sequence, wherein an orthogonal code is applied to the plurality of second SC-FDMA symbols in a time domain.

    Abstract: The present invention relates to a wireless communication system, and more particularly, to a method and an apparatus for accessing a channel in a wireless LAN system. According to one embodiment of the present invention, a method for performing channel access by a station (STA) of a wireless communication system comprises: a step of receiving, from an access point (AP), information about the time window which does not allow channel access of a traffic indication map (TIM) mode STA; and a step of performing channel access based on the time window. In the event that the STA is a non-TIM mode STA, the channel access is performed in the time window. In the event that the STA is a TIM mode STA, the channel access is performed in the time interval indicated by the TIM, excluding the time window.

    Abstract: A method is described for receiving a downlink control information (DCI) from a base station (BS) by a user equipment (UE) in a wireless communication system. The method includes monitoring a plurality of physical downlink control channel (PDCCH) candidates having the same payload size in a common search space and a UE-specific search space on a primary cell to receive the DCI. The common search space and the UE-specific search space are overlapped. If the UE is configured with a carrier indicator field (CIF), the method further includes determining that only a PDCCH in the common search space is transmitted from among the plurality of PDCCH candidates.
