Abstract: An operating method of a receiver includes detecting a signal received from a transmitter at a plurality of sub-bands constituting the frequency band, determining first frequency offsets for the signal at reception sub-bands at which the signal has been detected among the plurality of sub-bands, and determining second frequency offsets by calibrating carrier frequency offsets based on a distance of each of the reception sub-bands from a center frequency of the frequency band.

Abstract: According to one embodiment of the present disclosure, a communication method of an AP using multiple antennas can be provided, comprising the steps of: setting two or more transmission descriptors including unit transmission information in which antenna combination information and transmission rate information are defined; transmitting a packet using one of the set transmission descriptors; receiving information indicating whether the transmitted packet is a success or not; and collecting the information indicating whether the transmitted packet is a success or not for a predetermined period to reset the transmission descriptors. In addition, an apparatus using the method can be provided.

Abstract: The present disclosure relates to a 5G or pre-5G communication system to be provided in order to support higher data rates after a 4G communication system, such as an LTE system. A method for receiving buffer status information by an access point in a wireless communication system is provided. In the method, a contention sub-slot and a dedicated sub-slot are determined for each station connected to the access point, a data trigger action frame is generated based on a first element including allocation information on the dedicated sub-slot to be used by a related station in a buffer status report (BSR) phase where each of the stations transmits buffer status information to the access point, the generated data trigger action frame is broadcasted to the stations, and a BSR frame transmitted based on the data trigger action frame is received from each of the stations.

Abstract: A station (STA) that communicates with an access point (AP) in a Wireless Local Area Network (WLAN) system includes a transceiver configured to support transmission and reception of signals within at least a first bandwidth and to receive a first physical layer protocol data unit (PPDU) conforming to a second bandwidth greater than the first bandwidth, and processing circuitry configured to support a wider bandwidth than the first bandwidth by obtaining a second PPDU allocated to the STA within the first bandwidth from the first PPDU. The processing circuitry is configured to control the transceiver to transmit, to the AP, performance information indicating first modulation and coding schemes (MCSs) supportable in the wider bandwidth according to a capability of the STA, among a plurality of candidate MCSs.

Abstract: A 5th generation (5G) or a pre-5G communication system to support a higher data transmission rate than a system after a 4th generation (4G) communication system such as long-term evolution (LTE) is provided. A method of determining a carrier sense threshold by one source terminal in a wireless communication system is provided. The method includes identifying whether one or more interferer terminals and one or more destination terminals exist for one source terminal, and if the terminals exist, determining a carrier sense threshold of each of the one or more interferer terminals and the one or more destination terminals based on an interference intensity received from the one or more destination terminals and a feedback link margin.
