Preferably, the beacon frame carries a first time-frequency resource for the access point device and the target station device to establish an initial communication connection in the other frequency band, where the first time-frequency resource is located in a non-contention period, and the first time-frequency resource includes a time resource and a frequency resource.

It can be understood that, specifically, the first time-frequency resource may be carried in a beacon frame broadcast in a target frequency band, so that a target station device that has listened to the beacon frame establishes an initial communication connection with an access point device using the first time-frequency resource located in a non-contention period (CFP) in another frequency band different from the target frequency band, to further reduce a probability of a channel contention conflict occurring during establishment of the initial communication connection between the access point device and the station device, and to prevent a station device that does not support the next-generation wireless simulation technique of ieee802.11ax from interfering with communication of the station device that supports the next-generation wireless simulation technique of ieee802.11ax in the time period to establish the initial connection between the station device and the access point device.

Moreover, the station device, which does not support the next generation wireless simulation technology of ieee802.11ax, generally knows the lengths of the contention period CP and the non-contention period CFP by parsing the information elements of the contention period CP and the non-contention period CFP, respectively; however, the station apparatus supporting the ieee802.11ax next generation wireless simulation technology knows the length of the non-contention period CFP by parsing the information element of the non-contention period CFP, and also knows the allocated time-frequency resources only for the purpose of initial communication connection between the station apparatus and the access point apparatus by parsing the information element for allocating the time-frequency resources.

In this embodiment, when a station device supporting the ieee802.11ax next generation wireless fidelity technology listens to and receives a beacon frame generated by an access point device broadcasting in a target frequency band selected by the access point device, parses the beacon frame to establish an initial communication connection with the access point device, thereby further implementing data transmission between the access point device and the station device, and considering that the ieee802.11ax next generation wireless fidelity technology requires higher throughput than the existing wireless fidelity technology, for a station device supporting the ieee802.11ax next generation wireless fidelity technology and listening to the beacon frame, specifically, according to the beacon frame, establishes an initial communication connection with the access point device in another frequency band different from the target frequency band, so as to effectively reduce the probability of channel contention conflict occurring during establishment of the initial communication connection between the station device and the access point device, that is, to distinguish from a station device not supporting the ieee802.11ax next generation wireless fidelity technology, that is, it is not necessary to establish an initial communication connection with the access point device in a contention channel manner according to the beacon frame in the target frequency band, so that the technical scheme can achieve the purpose of improving the system throughput, and can improve the spectrum utilization efficiency, thereby saving more power for the device.

Further, step 404 in the foregoing embodiment may be specifically implemented as the flow steps described in fig. 7, including:

step 4042, analyzing and acquiring the first time-frequency resource carried in the beacon frame, where the first time-frequency resource is located in a non-contention period, and the first time-frequency resource includes a time resource and a frequency resource.

Step 4044, an initial connection frame is transmitted to the access point device using the first time/frequency resource in the other frequency band.

Step 4046, receiving a connection response frame corresponding to the initial connection frame, where the connection response frame is sent by the access point device using the first time-frequency resource, where the connection response frame carries a second time-frequency resource used for performing initial communication connection verification.

Step 4048, the station device and the access point device establish an initial communication connection using the second time-frequency resource.

In this embodiment, specifically, the station device and the access point device respectively use the first time-frequency resource in the non-contention period (CFP) carried in the beacon frame to perform transmission of an initial connection frame and a connection response frame in another frequency band different from the target frequency band, so as to reduce the probability of channel collision during the process of establishing an initial communication connection between the station device and the access point device and prevent the station device that does not support the next-generation wireless simulation technique of ieee802.11ax from establishing an initial connection between the station device and the access point device, where the station device does not support the next-generation wireless simulation technique of ieee802.11ax in communication interference during this time period and supports the next-generation wireless simulation technique of ieee802.1ax; further, in order to avoid the occurrence of a contention mechanism in the process of establishing the initial communication connection between the two, the station device performs connection verification of the access point device by analyzing and acquiring the second time-frequency resource contained in the connection response frame received by using the first time-frequency resource, so as to verify the identity validity.

Wherein, the initial connection frame is an association request frame; and further, in order to ensure that the station device and the access point device can establish communication and connection smoothly, acquiring and recording the BSSID or MAC address of the access point device in the process of analyzing the beacon frame to acquire the first time-frequency resource, so as to establish correct connection with the matched access point device according to the BSSID or MAC address.

In this embodiment, the frequency resources included in the first time-frequency resources acquired by analyzing the beacon frame are a plurality of small resource blocks obtained by dividing the corresponding communication bandwidth in another frequency band different from the target frequency band of the beacon frame broadcast by the access point device, and each resource block has a corresponding number, for example, the communication bandwidth of 20MHz can be divided into 5 sub-bandwidths of 4MHz (i.e. 5 small resource blocks) which are respectively numbered as 0, 1, 2, 3 and 4, further, the number of OFDM sub-carriers included in each sub-bandwidth can be 10, so that the target station device supporting ieee802.11ax can randomly select the number of the resource block and listen to the beacon frame, and further transmit the initial connection frame using the resource block corresponding to the selected number, for example, randomly select number 2, and transmit the initial connection frame using the sub-band width of 4MHz corresponding to number 2, the purpose of sending the initial connection frame can be achieved by only using a part of the whole frequency resources, so that the purpose of improving the utilization efficiency of the frequency spectrum is achieved.
