Information processing method, electronic equipment and terminal

Technical Field

The present invention relates to information processing technologies, and in particular, to an information processing method, an electronic device, and a terminal.

Background

In the institute of electrical and electronics engineers IEEE 802.11 new edition wireless communication protocol, the communication system bandwidth is extended to 80MHz, even 160 MHz; such a large system bandwidth enables a significant increase in the transmission rate of data. Electronic equipment such as a notebook computer, a mobile phone and the like supporting an old-version STA of an 802.11 communication protocol can only work in a bandwidth of 20MHz or 40 MHz. The new version of the workstation STA, which supports the new version of the 802.11 communication protocol, can operate in the bandwidth of 80MHz or 160 MHz.

When the AP sends downlink data to the old STA and the new STA simultaneously, taking the AP using a channel bandwidth of 80MHZ (megahertz) to perform data transmission with the two types of STAs as an example, the new STA can fully utilize the bandwidth resources; since the operating bandwidth of the legacy STA is small, for example, the operating bandwidth is 20MHZ, in the bandwidth of 80MHZ, a large bandwidth, for example, 80MHZ-20MHZ, 60MHZ, will be in an idle state. At present, when the AP adopts a transmission mode with a higher bandwidth, such as 80MHz or 160MHz, how to improve the bandwidth utilization rate when performing data transmission on the old-version STA becomes a problem to be solved urgently.

Detailed Description

In the related art, when the AP transmits data to the old STA by using a transmission method with a higher bandwidth, for example, using a bandwidth of 80MHz or 160MHz, since the operating bandwidth of the old STA is smaller, a larger part of the bandwidth will be in an idle state in the transmission bandwidth, and how to improve the bandwidth utilization ratio is one of the technical problems to be solved by the embodiment of the present invention. In addition, when the old version STA receives the downlink data sent by the AP, it returns an acknowledgement frame ACK to the AP on the corresponding channel to inform the STA that the downlink data sent by the AP has been successfully received. In the relevant standard, a scene that the AP simultaneously sends downlink data to the new STA and the old STA does not exist, so that the probability of successfully demodulating ACK by the AP is affected by the problem of how the new STA returns the ACK to the AP. That is to say, the embodiment of the present invention can improve the utilization rate of the frequency band resource, and can also improve the probability that the AP successfully demodulates the ACK of each STA. For the details provided by the present invention, reference should be made to the following description.

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described below are only for the purpose of illustrating and explaining the present invention, and are not to be construed as limiting the present invention.

In the following embodiments of the information processing method, the electronic device, and the terminal provided by the present invention, the first electronic device (electronic device) may be a base station, an AP, or the like; the first type of terminal and the second type of terminal (terminals) involved include but are not limited to: industrial control computers, personal computers, and the like, all types of computers, all-in-one computers, tablet computers, mobile phones, electronic readers, and the like. The preferred object of the first class terminal and the second class terminal in the embodiment of the invention is a mobile phone.

Method embodiment one

The first embodiment of the information processing method applied to the electronic device such as the access point provided by the invention can communicate with the first type terminal and the second type terminal through the first channel. Preferably, the first type terminal may be a legacy STA operable in a bandwidth of 20MHz or 40 MHz; the second class of terminals may be new versions of STAs that may operate at bandwidths of 80MHz or 160 MHz. Of course, this embodiment may also be applied to the case where the AP simultaneously transmits downlink data to at least two STAs operating in different bandwidths.

Fig. 1 is a schematic flow chart of an implementation of a first embodiment of an information processing method applied to an AP according to the present invention; as shown in fig. 1, the method includes:

step 101: determining a first sub-channel used for transmitting first data to a first type of terminal in the first channel;

here, when the AP wants to transmit downlink data to the old STA and the new STA simultaneously, the channel resources that the AP can carry are divided, for example, the channel resources are divided into a primary channel resource used when downlink data is transmitted to the old STA and a secondary channel resource used when downlink data is transmitted to the new STA. The main channel resource is the first sub-channel and is used when the AP transmits downlink data to an old STA. The channel resources at least comprise transmission bandwidth, carrier resources and the like; for the definition of the channel resources, reference is made to the related description of the 802.11 protocol, which is not specifically described here. Here, for example, regarding the division of the channel resources, taking an example that the AP performs downlink data transmission to the two types of STAs by using a channel bandwidth of 80MHZ, if the operating bandwidth of the old-version STA is 20MHZ, the bandwidth resource of 20MHZ is divided as a first sub-channel, and the remaining bandwidth resource of 80-20, that is, the bandwidth resource of 60MHZ is used as a second sub-channel.

Step 102: determining a resource in the first channel different from the first sub-channel as a second sub-channel;

here, it is preferable that the channel resources used by the old-version STAs, such as primary channel resources, be allocated first, and the remaining channel resources be allocated to the new-version STAs. The second sub-channel is the remaining channel resource, and is also the aforementioned auxiliary channel resource, and is used when the AP transmits downlink data to the new STA.

Step 103: performing first modulation on the first data and the second data to obtain third data, wherein the second data is data transmitted to a second type of terminal, and data corresponding to different terminals in the third data has orthogonality;

here, the first modulation is Orthogonal Frequency Division Multiplexing (OFDM) modulation; the first data is downlink data which the AP wants to transmit to the old version STA; the second data is downlink data which the AP wants to transmit to the new STA. Before the AP simultaneously transmits downlink data to the two types of STAs, OFDM modulation needs to be performed on the first data and the second data to obtain data subjected to orthogonal modulation, that is, third data.

In this embodiment, the data transmitted to the two different STAs is kept in quadrature modulation by using the OFDM modulation technique. The first data and the second data are subjected to OFDM modulation by a method of performing serial-to-parallel conversion on the first data and the second data, performing Inverse Discrete Fourier Transform (IDFT), and inserting a symbol guard interval, and for a specific implementation process of OFDM modulation, reference is made to the related description, which is not repeated herein. In this embodiment, when performing OFDM modulation, the subcarrier resources used for modulating first data and the subcarrier resources used for modulating second data are orthogonal carriers, and it is ensured that the carrier spacing between the subcarriers used for modulating first data is the same as the carrier spacing between the subcarriers used for modulating second data, the period of performing IDFT on first data is the same as the period of performing IDFT on second data, and the symbol guard interval inserted for first data is the same as the symbol guard interval inserted for second data.

Step 104: carrying information corresponding to the first data in the third data on a first sub-channel and information corresponding to the second data on the second sub-channel;

here, the downlink data in the third data after OFDM modulation, which needs to be transmitted to the old STA, is carried on the channel resource allocated to the old STA, and the downlink data in the third data, which needs to be transmitted to the new STA, is carried on the channel resource allocated to the new STA.

Step 105: transmitting the third data in the first channel.

Here, the AP transmits the third data over the full frequency band; the downlink data transmitted to the old version STA is loaded on the first sub-channel, and the downlink data transmitted to the new version STA is loaded on the second sub-channel.

It should be known to those skilled in the art that, in the process of sending downlink data by the AP, the multiple access scheme adopted by the AP is an orthogonal frequency division multiple access OFDMA scheme, which can improve the frequency band utilization rate and avoid wasting frequency band resources.

Therefore, according to the scheme, the first sub-channel is allocated to the old version STA through allocation of the channel resources, the rest channel resources are used as the channel resources of the new version STA, orthogonal modulation is kept on the downlink data sent to the new version STA and the old version STA, the downlink data sent to different types of STAs are borne on the sub-channel resources allocated to the corresponding types of STAs, full-band transmission of the AP is achieved when the AP sends the downlink data to the two types of STAs at the same time, the problem of channel resource waste caused by small working bandwidth of the old version STA is solved, and the band utilization rate is effectively improved.

The first embodiment of the information processing method applied to the second type of terminal, such as a new version STA, provided by the invention, can communicate with the first electronic device, such as an AP.

Fig. 2 is a schematic flow chart illustrating an implementation of the information processing method applied to a second type of terminal, such as a new STA, according to the first embodiment of the present invention; as shown in fig. 2, the method includes:

step 201: receiving third data on the first channel;

here, the new STA receives the third data transmitted by the AP on the first channel.

Step 202: and demodulating information carried on a second sub-channel in the first channel, wherein the information is information corresponding to second data transmitted to the terminal by the first electronic equipment in third data to obtain second data.

Here, since the AP carries the downlink data transmitted to the new STA on the second sub-channel allocated to the new STA, when the new STA receives the third data, the AP demodulates the data carried on the second sub-channel to obtain the second data, which is the downlink data sent by the AP to the new STA.

According to the scheme, the new STA receives third data sent by the AP and demodulates the third data to obtain downlink data transmitted to the new STA by the AP.

For the old STA, the third data sent by the AP is received on the first channel, and the data carried on the first sub-channel is demodulated to obtain the first data, which is the downlink data sent by the AP to the new STA. For the foregoing procedure of receiving and demodulating data by the legacy STA, please refer to the 802.11 protocol, which is not described herein.

In the scheme, when the AP sends third data through the first channel, the old STA demodulates first data from the first sub-channel allocated to the old STA, and the new STA demodulates second data from the second sub-channel allocated to the new STA, that is, each STA demodulates downlink data sent by the AP on the sub-channel allocated to the new STA; the data acquisition of different types of STAs is facilitated.

Method embodiment two

The second method embodiment is based on the first method embodiment, and further describes the information processing method applied to the AP and the new STA.

Fig. 3 is a schematic flow chart of an implementation of a second embodiment of the information processing method applied to an AP according to the present invention; as shown in fig. 3, before the step 103 of performing the first modulation on the first data and the second data by the AP to obtain the third data, the method further includes:

step 103 a: detecting a first length of first data, and detecting a second length of second subdata corresponding to each second-class terminal in the second data, wherein the second data is data for transmitting at least one second-class terminal, and the second data comprises at least one second subdata;

in this embodiment, the number of old STAs with which the AP wants to communicate is usually one, and the number of new STAs may be at least one. The first data is payload data which is pre-sent to the old version STA by the AP; the second subdata is payload data which is pre-sent to each new version STA by the AP.

Before sending downlink data, the AP detects the length of data (first data) sent to the old version of STA and detects the length of data (second sub-data) sent to each new version of STA.

Step 103 b: judging whether the first length is equal to the second length;

here, the AP determines whether the length of data transmitted to the old version STA is equal to the length of data transmitted to each new version STA.

Step 103 c: when the first length is not equal to the second length, a first predetermined operation is performed to make the second length of the second sub-data equal to the first length.

Here, when the APs determine that they are not equal, a first predetermined operation, such as an add data operation or a truncate data operation, is performed to make the length of data transmitted to the old version STA equal to the length of data transmitted to each new version STA. When the length of the data sent to the old version STA is equal to the length of the data sent to each new version STA, the consistency of the downlink data sent by the AP to the two types of STAs is convenient to ensure, and the sending efficiency of the AP can be improved.

Further, step 103c is: when the second length is smaller than the first length, calculating a first difference value between the first length and the second length, adding third data of the first difference value at a first preset position of second subdata to obtain fourth data, and determining the fourth data as the second subdata; and when the second length is larger than the first length, intercepting the data with the first length at a second preset position in the second subdata to obtain fifth data, and determining the fifth data as the second subdata.

Here, for example, when the length of the second sub data sent to the new STA2 is smaller than the length of the first data sent to the old STA 1, a difference between the two lengths is calculated, for example, by 6 bits, 6 "0" s are added to the back of the second sub data, and the data to which the "0" s are added is taken as payload data that the AP wants to send to the new STA 2. When the length of the second subdata sent to the new version STA2 is greater than that of the first data sent to the old version STA 1, calculating the difference value of the two lengths, such as 3 bits, and intercepting the 1bit of the second subdata to the 4 th bit of the second subdata as the payload data which the AP wants to send to the new version STA 2; the last 3-bit data of the second subdata are deleted, so that the length of the payload data sent to the new version STA2 is equal to the length of the payload data sent to the old version STA 1. The payload data, i.e. the first data and the second data, is typically carried in a presentation layer protocol data unit data packet PPDU. In this embodiment, by adding or truncating the second sub-data sent to the new STA and making the second sub-data have the same length as the first sub-data sent to the old STA, consistency of sending downlink data to the two types of STAs by the AP can be ensured, and sending efficiency of the AP can be improved.

After the length of the second data transmitted to the new STA is subjected to the truncation or addition processing as described above, the second data to be transmitted to the new STA and the first data to be transmitted to the old STA are subjected to OFDM modulation, so that the first data and the second data are kept in orthogonal modulation. And then, carrying downlink data which needs to be transmitted to the old version STA in the third data after OFDM modulation on the channel resources allocated to the old version STA, carrying the downlink data which needs to be transmitted to the new version STA in the third data on the channel resources allocated to the new version STA, and sending the third data on the full frequency band by the AP. By allocating channel resources, such as allocating a first sub-channel to an old version STA and using the remaining channel resources as the channel resources of a new version STA, full-band transmission of the AP is realized when the AP simultaneously sends downlink data to the two types of STAs, the problem of channel resource waste caused by small working bandwidth of the old version STA is solved, and the utilization rate of the frequency band is effectively improved; meanwhile, the OFDM modulation mode is adopted, so that transmission interference between the first data and the second data can be avoided.

For the old STA, the third data sent by the AP is received on the first channel, and the data carried on the first sub-channel is demodulated to obtain the first data, which is the downlink data sent by the AP to the new STA. And feeds back an ACK frame to the AP for a predetermined time period, such as a predetermined Short Interframe Space (SIFS), to inform the AP that it has successfully received the first data sent by the AP. For the foregoing processing procedure of the legacy STA, please refer to the 802.11 protocol, which is not described herein.

Correspondingly, for an AP, the AP receives a first signal, where the first signal is a feedback signal for the first data sent by a first class of terminals; and when the first preset time is over, sending a first message to a preset second type terminal so that the preset second type terminal sends a feedback signal aiming at the second data to the first electronic equipment such as the AP. The first signal is an ACK frame fed back by the old STA. After receiving the ACK frame fed back by the old STA, the AP sends a first message, such as a BAR message, to a designated new STA, such as the new STA numbered 1, after a predetermined time, such as SIFS, is finished, so as to ask for the ACK frame to the new STA numbered 1.

Fig. 4 is a schematic flow chart illustrating an implementation of a second embodiment of the information processing method applied to a second type of terminal, such as a new STA, according to the present invention; as shown in fig. 4, after the new STA parses out the second data sent to it by the AP, the method further includes:

step 203: detecting whether a first message is received or not, and generating a first detection result, wherein the first message is sent by first electronic equipment;

here, a new STA, for example, the new STA numbered 1, demodulates the downlink data sent to it by the AP, and then detects whether a BAR message is received.

Step 204: and when the first detection result is characterized in that the first message is received, sending a second signal to the first electronic device, wherein the second signal is a feedback signal of the terminal aiming at second data sent by the first electronic device.

Here, when the new STA version number 1 detects that the BAR message has been received, it feeds back an ACK frame to the AP to inform the AP of successfully receiving the downlink data sent by the AP.

Since the AP knows the number of new and old STAs communicating with the AP and also knows the SIFS time value, it can estimate in advance the time information of feeding back ACK frames from the transmission of downlink data to all STAs, and configure the time information in the Duration information of the downlink data and transmit the information. Therefore, after other devices in the network, such as other APs or STAs, analyze the time information, the channel is not accessed in the time period, and the bandwidth resource is not shared with the AP, so that the working efficiency of the AP can be improved.

According to the scheme, for the downlink data sent by the AP to the old STA and the new STA, after the old STA feeds back the ACK frame, the new STA feeds back the ACK frame. The orderly feedback of the new and old versions of the STA realizes the orderly reception of the ACK frame by the AP, thereby improving the probability of successfully demodulating the ACK frame by the AP.

Apparatus embodiment one

According to the first embodiment of the electronic device, such as the access point AP, the AP can communicate with the first class terminal and the second class terminal through the first channel. Preferably, the first type terminal may be a legacy STA operable in a bandwidth of 20MHz or 40 MHz; the second class of terminals may be new versions of STAs that may operate at bandwidths of 80MHz or 160 MHz. Of course, this embodiment may also be applied to the case where the AP simultaneously transmits downlink data to at least two STAs operating in different bandwidths.

Fig. 5 is a schematic structural diagram of a first embodiment of an AP provided in the present invention; as shown in fig. 5, the AP includes: a first determining unit 501, a second determining unit 502, a first modulating unit 503, a first carrying unit 504 and a first sending unit 505; wherein,

a first determining unit 501, configured to determine a first sub-channel in the first channel for transmitting first data to a first class of terminals;

here, when the AP, specifically the first transmitting unit 505, wants to transmit downlink data to the old STA and the new STA simultaneously, the first determining unit 501 divides the channel resources that the AP can carry, such as a primary channel resource used when downlink data is transmitted to the old STA and a secondary channel resource used when downlink data is transmitted to the new STA. The main channel resource is the first sub-channel and is used when the AP transmits downlink data to an old STA. The channel resources at least comprise transmission bandwidth, carrier resources and the like; for the definition of the channel resources, reference is made to the related description of the 802.11 protocol, which is not specifically described here. Here, for example, regarding the division of the channel resources, taking an example that the AP performs downlink data transmission to the two types of STAs by using a channel bandwidth of 80MHZ, if the operating bandwidth of the old-version STA is 20MHZ, the bandwidth resource of 20MHZ is divided as a first sub-channel, and the remaining bandwidth resource of 80-20, that is, the bandwidth resource of 60MHZ is used as a second sub-channel.

here, it is preferable that the first determination unit 501 allocates the channel resource used by the old-version STA, for example, the primary channel resource, first, and the second determination unit 502 determines that the remaining channel resource can be allocated to the new-version STA. The second sub-channel is the remaining channel resource, and is also the aforementioned auxiliary channel resource, and is used when the AP transmits downlink data to the new STA.

A first modulation unit 503, configured to perform first modulation on the first data and second data to obtain third data, where the second data is data transmitted to a second class of terminals, and data corresponding to different terminals in the third data has orthogonality;

here, the first modulation is Orthogonal Frequency Division Multiplexing (OFDM) modulation; the first data is downlink data which the AP wants to transmit to the old version STA; the second data is downlink data which the AP wants to transmit to the new STA. Before the AP, specifically the first sending unit 505, simultaneously transmits downlink data to the two types of STAs, the first modulating unit 503 is required to perform OFDM modulation on the first data and the second data, so as to obtain data after orthogonal modulation, that is, third data.

In this embodiment, the first modulation unit 503 keeps the data transmitted to the two different STAs in quadrature modulation by using the OFDM modulation technique. The first modulation unit 503 performs OFDM modulation on the first data and the second data by performing serial-to-parallel conversion on the first data and the second data, performing Inverse Discrete Fourier Transform (IDFT), and inserting a symbol guard interval, and please refer to the related description for the specific implementation process of OFDM modulation, which is not described herein again. In this embodiment, when performing OFDM modulation, the subcarrier resources used for modulating first data and the subcarrier resources used for modulating second data are orthogonal carriers, and it is ensured that the carrier spacing between the subcarriers used for modulating first data is the same as the carrier spacing between the subcarriers used for modulating second data, the period of performing IDFT on first data is the same as the period of performing IDFT on second data, and the symbol guard interval inserted for first data is the same as the symbol guard interval inserted for second data.

here, the AP, specifically, the first bearer unit 504 bearers downlink data, which needs to be transmitted to the old STA, in the third data after OFDM modulation on the channel resource allocated to the old STA, and bearers downlink data, which needs to be transmitted to the new STA, in the third data on the channel resource allocated to the new STA.

According to the first embodiment of the second type of terminal, provided by the invention, such as the new STA, the new STA can communicate with the first electronic device, such as the AP.

The first data is payload data which is pre-sent to the old version STA by the AP; the second subdata is payload data which is pre-sent to each new version STA by the AP. Before the AP, specifically the first sending unit 505 sends downlink data, the first detecting unit 506 detects the length of data (first data) sent to the old STA and detects the length of data (second sub-data) sent to each new STA. The AP, specifically, the first detection unit 506, determines whether the length of the data sent to the old version STA is equal to the length of the data sent to each new version STA. When the APs are determined to be unequal, the first detecting unit 506 performs a first predetermined operation, such as an add data operation or a truncate data operation, to make the length of data transmitted to the old version STA equal to the length of data transmitted to each new version STA. When the length of the data sent to the old version STA is equal to the length of the data sent to each new version STA, the consistency of the downlink data sent by the AP to the two types of STAs is convenient to ensure, and the sending efficiency of the AP can be improved.

Further, the AP, specifically the first detecting unit 506 is further configured to calculate a first difference between the first length and the second length when the second length is smaller than the first length, add third data, which is the first difference, to a first predetermined position of the second sub-data to obtain fourth data, and determine that the fourth data is the second sub-data; and when the second length is larger than the first length, intercepting the data with the first length at a second preset position in the second subdata to obtain fifth data, and determining the fifth data as the second subdata.

Here, for example, when the length of the second sub-data sent to the new STA2 is smaller than the length of the first data sent to the old STA 1, the AP, specifically, the first detection unit 506 calculates a difference between the two lengths, for example, a difference of 6 bits, adds 6 "0" s to the back of the second sub-data, and takes the data to which the "0" is added as payload data that the AP wants to send to the new STA 2. When the length of the second subdata sent to the new version STA2 is greater than the length of the first data sent to the old version STA 1, the AP, specifically, the first detection unit 506 calculates the difference between the two lengths, for example, the difference is 3 bits, and intercepts the 1bit of the second subdata to the 4 th bit of the second subdata as payload data which the AP wants to send to the new version STA 2; the last 3-bit data of the second subdata are deleted, so that the length of the payload data sent to the new version STA2 is equal to the length of the payload data sent to the old version STA 1. The payload data, i.e. the first data and the second data, is typically carried in a presentation layer protocol data unit data packet PPDU. In this embodiment, by adding or truncating the second sub-data sent to the new STA and making the second sub-data have the same length as the first sub-data sent to the old STA, consistency of sending downlink data to the two types of STAs by the AP can be ensured, and sending efficiency of the AP can be improved.

After the AP, specifically the first detecting unit 506, performs the truncation or addition processing on the length of the second data sent to the new STA, as described above, the AP, specifically the first modulating unit 503, performs OFDM modulation on the second data to be sent to the new STA and the first data to be sent to the old STA, so that the first data and the second data are kept in orthogonal modulation. The AP, specifically, the first bearer unit 504 further bearers downlink data, which needs to be transmitted to the old-version STA, in the third data after OFDM modulation on the channel resource allocated to the old-version STA, bearers downlink data, which needs to be transmitted to the new-version STA, in the third data on the channel resource allocated to the new-version STA, and the AP, specifically, the first transmission unit 505 transmits the third data over the full frequency band. By allocating channel resources, such as allocating a first sub-channel to an old version STA and using the remaining channel resources as the channel resources of a new version STA, full-band transmission of the AP is realized when the AP simultaneously sends downlink data to the two types of STAs, the problem of channel resource waste caused by sending the downlink data to the old version STA is solved, and the utilization rate of the frequency band is effectively improved; meanwhile, the OFDM modulation mode is adopted, so that transmission interference between the first data and the second data can be avoided.

Correspondingly, for the AP, as shown in fig. 7, the AP further includes a first receiving unit 507 and a second transmitting unit 508; wherein,

a first receiving unit 507, configured to receive a first signal, where the first signal is a feedback signal for the first data sent by a first class terminal;

a second sending unit 508, configured to send a first message to a predetermined second class of terminals when the first predetermined time is over, so that the predetermined second class of terminals sends a feedback signal for the second data to an electronic device, such as an AP.

The first signal is an ACK frame fed back by the old STA. After the AP, specifically the first receiving unit 507 receives the ACK frame fed back by the old STA, when a predetermined time such as SIFS is over, the second sending unit 508 sends a first message such as a BAR message to a designated new STA, for example, a new STA numbered 1, to ask for the ACK frame from the new STA numbered 1.

Fig. 8 is a schematic structural diagram illustrating a second embodiment of a new STA version according to the present invention; as shown in fig. 8, the new version STA further includes: a first detection unit 603 and a first transmission unit 604; wherein,

a first detecting unit 603, configured to detect whether a first message is received and generate a first detection result, where the first message is sent by an electronic device;

here, a new STA, for example, a new STA numbered 1, specifically, the first detecting unit 603 detects whether a BAR message is received after the first demodulating unit 602 demodulates the downlink data sent to it by the AP.

A first sending unit 604, configured to send a second signal to the electronic device when the first detection result generated by the first detecting unit 603 indicates that the first message is received, where the second signal is a feedback signal of second data sent by the terminal for the electronic device.

Here, when the new STA version number 1, specifically the first detection unit 603, detects that the BAR message has been received, the first transmission unit 604 feeds back an ACK frame to the AP to inform the AP that it successfully receives the downlink data that the AP transmits it.

Since the AP knows the number of the new and old STAs communicating with the AP and also knows the SIFS time value, the AP, specifically, the first estimating unit (not shown in fig. 5 and 7) may estimate in advance the time information of feeding back the ACK frame from the downlink data transmission to all STAs, and the first configuring unit (not shown in fig. 5 and 7) configures the information in the Duration information of the downlink data and transmits the Duration information. Therefore, after other devices in the network, such as other APs or STAs, analyze the time information, the channel is not accessed in the time period, and the bandwidth resource is not shared with the AP, so that the working efficiency of the AP can be improved.
