Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a wireless data transmission method and apparatus, a storage medium, and an STA.
Background
In a conventional Institute of Electrical and Electronics Engineers (IEEE) 802.11 protocol, IEEE802.11, a system with only a single link is defined, for example, a Wireless Local Area Network (WLAN) protocol. As technology evolves, a synchronous multilink system transport is discussed in 802.11 be.
In the wireless data Transmission technology, Transmission Opportunity (TXOP) contention is an important content of wireless channel access, and is composed of an initial time and a maximum duration (TXOP limit). Specifically, the TXOP may be obtained through contention or allocation, and a station that obtains the TXOP may continuously use the channel to transmit multiple data frames within the TXOP limit time without re-contending for the channel.
In a single link system, due to adjacent channel interference, the usable bandwidth of a transmitting end or a receiving end is often limited due to the existence of interference, and in addition, the usable bandwidth between the transmitting end and the receiving end may also be different, so that various bandwidth combinations exist, and the transmission efficiency is low because a smaller bandwidth is often adopted to transmit data in order to meet the requirement of a smaller bandwidth party. For example, Primary20, Primary40, Primary80, or other bandwidths may be employed, respectively. Wherein, when the status of the Primary channel (for example, 20MHz channel) (for example, channel 1) is idle, and the status of the rest non-Primary channels is busy, "Primary 20" can be used, and the available bandwidth is 20 MHz. When the status of the Primary channel (e.g., 40MHz channel) (e.g., channels 1, 2) is idle and the status of the remaining non-Primary channels is busy, "Primary 40" can only be used, and the available bandwidth is 40 MHz. When the status of the Primary channel (e.g., 80MHz channel) (e.g., channels 1, 2, 3, and 4) is idle and the status of the remaining non-Primary channels is busy, "Primary 80" can only be used, and the available bandwidth is 80 MHz.
This problem is more serious in the case of a synchronous multilink system, and the problem of low transmission efficiency is more likely to occur. Specifically, in the synchronous multilink system, regardless of whether a wireless data transmission bandwidth parameter (for example, a latest wireless data transmission bandwidth) is large or small, a reciprocal value is randomly determined based on the same backoff window, and then reciprocal values are performed by using the same reciprocal reduction step, so that a smaller available bandwidth (for example, 20MHz) or a larger available bandwidth (for example, 80MHz) has a similar probability of being selected for transmitting wireless data, thereby causing a problem that the data transmission efficiency of the system is low when the smaller available bandwidth is used.

Detailed Description
As described above, in the single link system of the conventional wireless data transmission technology, in an interference environment, the available bandwidth of the transmitting end or the receiving end is often limited due to the existence of interference, and the available bandwidth between the transmitting end and the receiving end may also be different, so that there are various bandwidth combinations, and the transmission efficiency is low because the data is often transmitted with a smaller bandwidth in order to meet the requirement of the smaller bandwidth. For example, Primary20, Primary40, Primary80, or other bandwidths may be employed, respectively. Wherein, when the status of the Primary20 MHz channel (e.g., channel 1) is idle and the status of the other non-Primary channels is busy, "Primary 20" can be used only, and the available bandwidth is 20 MHz. When the status of the Primary40 MHz channel (e.g., channels 1, 2) is idle and the status of the remaining non-Primary channels is busy, only "Primary 40" can be used, and the available bandwidth is 40 MHz. When the status of the Primary80 MHz channels (e.g., channels 1, 2, 3, and 4) is idle and the status of the remaining non-Primary channels is busy, only "Primary 80" can be used, where the available bandwidth is 80 MHz.
The inventor of the present invention has found, through research, that in a synchronous multilink system in the prior art, since an actual reciprocal value is randomly determined based on the same backoff window no matter whether a wireless data transmission bandwidth parameter (for example, a latest wireless data transmission bandwidth) is large or small, a smaller available bandwidth (for example, 20MHz) or a larger available total bandwidth (for example, 80MHz) has a similar probability of being selected for transmitting wireless data, thereby causing a problem that when the smaller available bandwidth is used, the data transmission efficiency of the system is low.
In the embodiment of the invention, an original backoff window is determined; based on the original backoff window, randomly determining a reciprocal initial value, and performing reciprocal by adopting the reciprocal initial value; at each reciprocal time interval, if the state of the primary channel is idle, determining the available total bandwidth, and determining the reciprocal reduction step size at the reciprocal time interval according to the available total bandwidth; according to the reciprocal reduction step length, obtaining an updated reciprocal value at each reciprocal time interval; and when the updated reciprocal value is less than or equal to zero and the control right of the TXOP is obtained, adopting the TXOP to send the wireless data. By adopting the scheme, the upper limit value of the actual backoff window can be adjusted by setting the window upper limit offset of the original backoff window, so that when the actual reciprocal value is randomly determined based on the actual backoff window, different wireless data transmission bandwidth parameters with different window upper limit offsets are set in an opportunity, and after the actual reciprocal value is randomly determined based on the actual backoff window, the probability that a larger available total bandwidth (such as 80MHz) is selected is favorably improved, so that the data transmission efficiency of a system is improved by adopting higher bandwidth transmission in an opportunity.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a flowchart of a wireless data transmission method according to an embodiment of the present invention. The wireless data transmission method may be used for a Station (Station, STA), and may include steps S11 to S15:
step S11: determining an original backoff window;
step S12: based on the original backoff window, randomly determining a reciprocal initial value, and performing reciprocal by adopting the reciprocal initial value;
step S13: at each reciprocal time interval, if the state of the primary channel is idle, determining the available total bandwidth, and determining the reciprocal reduction step size at the reciprocal time interval according to the available total bandwidth;
step S14: according to the reciprocal reduction step length, obtaining an updated reciprocal value at each reciprocal time interval;
step S15: and when the updated reciprocal value is less than or equal to zero and the control right of the TXOP is obtained, adopting the TXOP to send the wireless data.
In a specific implementation of step S11, an original backoff window (back of window) may be determined in an appropriate manner.
In one prior art, the step of obtaining control of the TXOP via TXOP contention by the STA may include: the reciprocal initial value is randomly determined from the backoff window. In the embodiment of the present application, the original backoff window may be determined by using a backoff window determination method in the prior art.
In a specific implementation of step S12, a reciprocal initial value may be randomly determined based on the original backoff window by a reciprocal method in the prior art, and reciprocal is performed by using the reciprocal initial value.
In a specific implementation of step S13, at each reciprocal time interval (back off interval), when the status of the primary channel (e.g., 20MHz) is idle, the available total bandwidth is determined, and the reciprocal reduction step size at the reciprocal time interval is determined according to the available total bandwidth.
Wherein the Available Total Bandwidth (ATBW) is used to indicate an Available Total Bandwidth that may be used when the STA sends data after the countdown interval if the STA sends data after the countdown interval. Specifically, if the wireless data transmission method is used for single-link data transmission, the available total bandwidth may be regarded as an available bandwidth of one link, for example, an available bandwidth of the single link; if the wireless data transmission method is used for multi-link data transmission, the available total bandwidth can be regarded as the sum of the available bandwidths of the plurality of links.
Further, the step of determining a reciprocal decrease step size at the reciprocal time interval based on the total available bandwidth may comprise: the larger the total bandwidth available, the larger the reciprocal reduction step size at the reciprocal time interval may be.
In the embodiment of the invention, the larger available total bandwidth has larger reciprocal reduction step length, so that the reciprocal times are easier to be reciprocal to zero by adopting fewer reciprocal times, namely when a plurality of STAs with different transmission bandwidths compete for the channel, the probability that the STA with the larger available total bandwidth (such as 80MHz) successfully competes for the channel is improved, and the system has higher opportunity to adopt higher bandwidth transmission so as to improve the data transmission efficiency of the system.
Still further, the reciprocal decrease step size may be linear with the total available bandwidth.
In the embodiment of the present invention, by setting the reciprocal reduction step size to have a linear relationship with the total available bandwidth, the probability that a larger total available bandwidth (e.g., 80MHz) is selected can be uniformly increased, so that the data transmission efficiency of the system is improved, and the data transmission stability of the system is maintained.
Further, the reciprocal reduction step size may be selected from integer and non-integer values.
Specifically, in the prior art, the reciprocal decrease step size is fixed to 1, but in the embodiment of the present invention, the reciprocal decrease step size may be set to a value other than 1, that is, may include a non-integer.
Still further, the reciprocal decrease step size may be selected from: 0.1 to 5.
In the embodiment of the present invention, the reciprocal reduction step is selected from integer and non-integer values, and compared with the prior art that only a fixed integer value can be selected, by adopting the scheme of the embodiment of the present invention, the data transmission efficiency of the system can be improved, and at the same time, the data transmission flexibility of the system can be improved.
Referring to fig. 2, fig. 2 is a schematic diagram of a relationship between an available total bandwidth and a reciprocal reduction step size according to an embodiment of the present invention.
Specifically, the reciprocal reduction step size and the available total bandwidth satisfy one or more of: if the total available bandwidth is 20MHz, the reciprocal decrease step size is 0.5; if the available total bandwidth is 40MHz, the reciprocal decrease step size is 1; if the total available bandwidth is 60MHz, the reciprocal decrease step size is 1.5; if the total available bandwidth is 80MHz, the reciprocal reduction step size is 2.
It should be noted that other suitable values of the reciprocal decrement step may also be adopted, and in the embodiment of the present invention, specific values of the reciprocal decrement step are not limited. For example, in another specific application, if the total available bandwidth is 20MHz, the reciprocal reduction step size is 0.4; if the total available bandwidth is 40MHz, the reciprocal decrease step size is 0.8; if the total available bandwidth is 60MHz, the reciprocal decrease step size is 1.2; if the total available bandwidth is 80MHz, the reciprocal reduction step size is 1.6; in yet another specific application, if the total available bandwidth is 20MHz, the reciprocal reduction step size is 1; if the total available bandwidth is 40MHz, the reciprocal decrease step size is 2; if the total available bandwidth is 60MHz, the reciprocal decrease step size is 3; if the total available bandwidth is 80MHz, the reciprocal reduction step size is 4.
With continued reference to fig. 1, in an implementation of step S14, an updated reciprocal value may be obtained at each reciprocal time interval based on the reciprocal decrement step.
Further, the step of obtaining an updated reciprocal value at each reciprocal time interval according to the reciprocal decrement step of the reciprocal time interval may include: at each countdown interval, subtracting the reciprocal value obtained at the countdown interval from the reciprocal value obtained at the previous countdown interval by the step size to obtain an updated reciprocal value.
Specifically, at each reciprocal time interval, when the state of the primary channel (e.g., 20MHz) is idle, the reciprocal value is calculated to successively subtract the current reciprocal reduction step size to obtain an updated reciprocal value.
It will be appreciated that at each reciprocal time interval, the reciprocal decrement step is determined in accordance with the current total bandwidth available.
In a specific implementation of step S15, when the updated reciprocal value is equal to or less than zero and the control right of the TXOP is obtained, the wireless data is transmitted using the TXOP.
In an embodiment of the present invention, when the updated reciprocal value is equal to or less than zero, a control right of the TXOP is immediately obtained, and the wireless data is sent using the TXOP.
It is understood that when the updated reciprocal value is zero and control of the TXOP is obtained, the wireless data may be transmitted using the TXOP in accordance with an appropriate conventional manner.
It should be noted that, in the embodiment of the present invention, since the reciprocal reduction step may be a non-integer or an integer greater than 1, the updated reciprocal value may be smaller than zero.
In a specific implementation manner of the embodiment of the present invention, if the available total bandwidth is 20MHz, the reciprocal reduction step size is 0.5; if the available total bandwidth is 40MHz, the reciprocal decrease step size is 1; it may thus happen that after a certain update the reciprocal value is 0.5, and in the next reciprocal time interval, if the status of the primary channel is idle and it is determined that the total bandwidth available is 40MHz, the reciprocal is decreased by a step size of 1, resulting in-0.5, i.e. less than zero.
In the embodiment of the present invention, the reciprocal reduction step length at the reciprocal time interval is determined according to the available total bandwidth, and then the reciprocal reduction step length at the reciprocal time interval is obtained, so as to obtain an updated reciprocal value at each reciprocal time interval, thereby giving an opportunity to use different reciprocal reduction step lengths.
Further, the wireless data transmission method may further include: and if the updated reciprocal value is less than zero, recording the updated reciprocal value as 0.
In the embodiment of the present invention, if the updated reciprocal value is less than zero, the updated reciprocal value is recorded as 0, so that a true negative number can be avoided.
