The present disclosure provides methods, components, devices, and systems for acknowledgement (ACK) processing associated with media access control (MAC) header verification, payload verification, or both. Some aspects are more particularly directed to a first wireless device announcing processing capabilities associated with performing MAC protocol data unit (MPDU) authentication, including MAC header authentication, payload authentication, or both. In some implementations, the processing capability may include a processing latency for performing authentication, a threshold number of MPDUs supporting authentication within a short inter-frame spacing (SIFS) time interval, or both. The first wireless device may send an indication of processing capability to the second wireless device. In some implementations, the second wireless device may transmit the MPDU to the first wireless device according to the processing capability. Additionally or alternatively, the first wireless device may transmit an ACK frame for the MPDU according to the processing capability.

The present disclosure relates to a method and device for retransmitting an initial control response in a wireless LAN system. A method performed by an electronic device operating as a first station (STA) in a wireless LAN network according to an embodiment of the present disclosure comprises the steps of: receiving an initial control frame (ICF) from a second STA; transmitting a first initial control response (ICR) to the second STA after a short inter frame space (SIFS) from a time point at which reception of the ICF is completed; and transmitting a second ICR corresponding to the first ICR to the second STA when a wireless medium (WM) is in an idle state until after a point coordination function inter frame space (PIFS) from a time point at which transmission of the first ICR is completed, and ICR retransmission is activated.

An apparatus configured to generate, for transmission, an initial control frame (ICF) for a transmission opportunity (TXOP) comprising a first duration and a second duration, wherein the first duration is set based on a time for a TXOP responder station to respond to the ICF with an initial control response (ICR) and a Short Interframe Space (SIFS), and wherein the second duration is set based on a time for data to be transmitted to the TXOP responder station, process, based on signaling received from the TXOP responder station, the ICR and generate, for transmission to the TXOP responder station, one or more data transmissions during the TXOP.

The invention relates to network allocation vector setting and updating during a transmit opportunity. An apparatus is configured to generate, for transmission, an initial control frame (ICF) for a transmit opportunity (TXOP), the initial control frame (ICF) including a first duration set based on a time required by a TXOP responder station to respond to the ICF with an initial control response (ICR) and a short inter-frame spacing (SIFS), and a second duration set based on a time required by the TXOP responder station to respond to the ICF with a short inter-frame spacing (SIFS). And wherein the second duration is set based on a time required to transmit data to the TXOP responder site; processing the ICR based on a signaling received from the TXOP responder station; and generating one or more data transmissions during the TXOP for transmission to the TXOP responder site.

The application discloses a method for measuring background noise of a communication channel, which comprises the following steps: switching a communication device from a first frequency point to a second frequency point in a short interframe interval after the communication device sends data, the first frequency point being a frequency point used by the communication device in an original transceiving process, and the second frequency point being a frequency point for which background noise is to be tested; opening a receiving channel of the communication device to sample signals; switching the frequency point of the communication device back to the first frequency point after the sampling is completed, and continuing the original transceiving process; and calculating the energy of the sampled signals as background noise. The application utilizes the characteristics of wireless communication to switch the frequency point of the communication device to the frequency point for which background noise is to be tested at a suitable time to collect background noise signals, the communication channel is in an idle state during the collection, and pure background noise can be easily detected, so that the reliability is high. Moreover, the method of the application completes the switching of the frequency and the collection of the signals in a short time, does not affect current communication, and is practical.
