Optionally, the wireless communication terminal is at least one of a mobile phone (mobile phone), a wearable device, an internet of things device supporting Wi-Fi communication function, an automobile with WiFi communication function, a smart car, a tablet (Pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in unmanned (self-driving), a wireless terminal device in teleoperation (remote medical surgery), a wireless terminal device in smart grid (SMART GRID), a wireless terminal device in transportation security (transportation safety), a wireless terminal device in smart city (SMART CITY), a wireless terminal device in smart home (smart home), but is not limited thereto.

Alternatively, the station device may support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a, 802.11bf, and 802.11bn, and support the next generation 802.11 protocol, but is not limited thereto.
In some embodiments, the access point device may be an access point where the mobile terminal enters a wired network. The AP acts as a bridge connecting the wired network and the wireless network, and is mainly used to connect the wireless network clients together and then access the wireless network to the ethernet.

It may be understood that, the communication system described in the embodiments of the present disclosure is for more clearly describing the technical solutions of the embodiments of the present disclosure, and is not limited to the technical solutions provided in the embodiments of the present disclosure, and those skilled in the art can know that, with the evolution of the system architecture and the appearance of new service scenarios, the technical solutions provided in the embodiments of the present disclosure are applicable to similar technical problems.
The embodiments of the present disclosure described below may be applied to the communication system 100 shown in fig. 1, or a part of the main body, but are not limited thereto. The respective bodies shown in fig. 1 are examples, and the communication system may include all or part of the bodies in fig. 1, or may include other bodies than fig. 1, and the number and form of the respective bodies may be arbitrary, and the respective bodies may be physical or virtual, and the connection relationship between the respective bodies is examples, and the respective bodies may not be connected or may be connected, and the connection may be arbitrary, direct connection or indirect connection, or wired connection or wireless connection.
Embodiments of the present disclosure may be applied to wireless local area networks (Wireless Local Area Network, WLAN), such as those employing 802.11 family of protocols. In WLAN, basic service set (BSS, basic SERVICE SET) is a Basic component of WLAN. A BSS network is made up of station devices having some association within a particular coverage area. One scenario of association is where stations communicate directly with each other in an ad hoc network, which is known as an independent BSS (IBSS, INDEPENDENT BASIC SERVICE SET). Another more common scenario is that only one central station with a full-time managed BSS in a BSS network is called an access point device, while other stations in the BSS network than an AP are called terminals, also called non-AP STAs, the AP and non-AP STAs being collectively called STAs. There is no need to distinguish between AP and non-AP STAs when describing STAs. In the same BSS network, one STA cannot detect other STAs far away from the STA due to distance, transmission power, and the like, and the two STAs are hidden nodes of each other.
Fig. 2 is an interactive schematic diagram of a communication method shown in accordance with an embodiment of the present disclosure. As shown in fig. 2, the method includes:
Step 201, a station device determines a first radio frame, where the first radio frame is used for initially performing frame exchange with the access point device in a first channel and requesting the access point device to acknowledge the first radio frame, where the first channel is a Non-primary channel access-primary channel (NPCA PRIMARY channels; NPCA is Non-PRIMARY CHANNEL ACCESS, non-primary channel access).
In Wi-Fi communication, a device may determine that a channel is busy or idle through both physical carrier sensing and virtual carrier sensing, and consider a current channel to be idle if and only if both physical carrier and virtual carrier sensing indicate that the channel is idle. Wherein the virtual carrier sense, i.e. whether it is idle or not, is determined by a network allocation vector (Network Allocation Vector, NAV) maintained by the device.
Alternatively, the NAV may be understood as a timer that defines the duration that the current channel needs to be occupied. In data communication, a device occupying a channel informs other devices of the channel occupying time through a Duration field in a packet. Devices that do not acquire channel resources maintain or update their own NAV values by comparing the Duration field values in the received packets. When the NAV value is 0, the virtual carrier sense considers that the current channel is idle.
In some embodiments, when the device detects that the primary channel (PRIMARY CHANNEL) is busy, the primary channel is considered busy, the device fails to contend for the channel, and no frame exchange can be performed. Typically, the transmission within a BSS with an operating bandwidth greater than 20MHz, the transmission channel of the PPDU comprises a 20MHz Primary channel. When Primary channel is busy, the device cannot exchange frames on Secondary channel even if Secondary channel (Secondary Channel, also called as "non-Primary channel") is idle in BSS, thus limiting the effective utilization of spectrum and throughput to a certain extent and being unfavorable for low-delay service transmission.
In some embodiments, under a Non-Primary channel access (Non-PRIMARY CHANNEL ACCESS, NPCA) mechanism, when the Wi-Fi device senses that the Primary channel is busy due to OBSS traffic communication, the Wi-Fi device may switch to the Non-Primary channel and perform channel contention access on the Non-Primary channel, and after successfully contending for the channel, may perform frame exchange within the Non-Primary channel. Therefore, the channel access or frequency utilization efficiency in the broadband system is further improved, and the transmission efficiency is improved.
In some embodiments, under the NPCA mechanism, after the NPCA device (i.e., the device supporting NPCA handover) switches from the Primary channel to the target channel (i.e., NPCA PRIMARY channels), the channel contention may be engaged by way of EDCA (Enhanced Distributed CHANNEL ACCESS ), and under the NPCA PRIMARY channel, the EDCA parameters engaged in the channel contention are the same as the BSS Primary channel parameters.
In some embodiments, under the NPCA mechanism, after a device successfully contends for a channel at NPCA PRIMARY channels, a frame exchange between its associated devices needs to be initiated over an initial control frame (Initial Control Frame, ICF). Alternatively, the initial control frame may be transmitted at a rate of 6 megabits per second (Mb/s), 12Mb/s, or 4Mb/s, and the PPDU carried by the initial control frame may be a non-HT PPDU or a non-HT duplicate PPDU.
In some embodiments, under the NPCA mechanism, the AP acts as a transmission opportunity holder (TXOP holder) on the NPCA PRIMARY channel, and may use a BSRP Trigger frame or a MU-RTS TRIGGER frame (Multi-User Request to SEND TRIGGER, multi-User Request transmission Trigger) as an initial control frame to initialize frame exchange with the STA.
In some embodiments, under the NPCA mechanism, a non-AP STA may use a BSRP GI3 frame as an initial control frame at NPCA PRIMARY channels as a TXOP holder to initiate frame exchanges with the AP.
In some embodiments, the BSRP GI3 frame is a variant of the BSRP Trigger frame. Optionally, an ultra-high reliability variant general information field (UHR variant Common Info field; UHR: ultra High Reliability, ultra-high reliability) may be carried in the BSRP Trigger frame, and UHR variant Common Info field may include a GI And HE/UHR Long training field type field (GI And HE/UHR-LTF TYPE FIELD, HE: HIGH EFFICIENCY, high efficiency; LTF: long TRAINING FIELD, long training field) And/or a transmission opportunity Sharing Mode field (TXS Mode field; TXS: TXOP Sharing; TXOP: transition opportunity). Optionally, the BSRP GI3 frame is a modified frame formed in the case that GIAnd HE in the BSRP Trigger frame is set to parameter value 3.
In some embodiments, under the NPCA mechanism, assuming that the STA uses the BSRP GI3 frame as an initial control frame, it initially exchanges operations with the AP in the frame under NPCA PRIMARY channels, at this time, the AP may need to respond to the BSRP GI3 frame in the form of a non-HT (duplicate) PPDU, but no relevant signaling currently defines how the AP responds to the BSRP GI3 frame.
In some embodiments, the station apparatus may determine the first radio frame after switching to NPCA PRIMARY channels and after successfully contending for the channels through the EDCA mechanism, and send the first radio frame to an AP associated therewith to initiate a frame exchange with the AP.
Alternatively, the first wireless frame may include, but is not limited to, a BSRP GI3 frame.
Alternatively, a first radio frame may be used to initially exchange frames with the access point device on a first channel and request the access point device to respond to the first radio frame with a non-HT (duplicate) PPDU. That is, the information that the access point device acknowledges the first radio frame is transmitted to the station device in a format of a non-HT (duplicate) PPDU.
Optionally, in BSRP GI3 frames, with GIAnd HE/UHR-LTF TYPE FIELD set to parameter value 3, the first radio frame may be used to initially exchange frames with the access point device on the first channel and request the access point device to respond to the first radio frame with a non-HT (duplicate) PPDU.
Optionally, in some embodiments, the receive address (RECEIVE ADDRESS, RA) field in the first radio frame may carry target receiver address information, which may include address information of the access point device.
Alternatively, the address information of the AP may include, but is not limited to, MAC (MEDIA ACCESS Control, medium access layer) address information of the AP. Alternatively, in the case where an AP is affiliated with an AP MLD, the address information of the AP may include, but is not limited to, MAC address information of the AP MLD to which the AP is affiliated.
Optionally, in some embodiments, address information of the station device may also be included in the first wireless frame.
Alternatively, the address information of the STA may include, but is not limited to, MAC (MEDIA ACCESS Control, medium access layer) address information of the STA.
