In a first embodiment, Fig. 1 a and Fig. 1 b is seen also.Fig. 1 a is starting stage within a unit interval (being also referred to as to train (train) flow process), carries out adjusting the schematic diagram of through-put power in a terminal B of a terminal A and a segment distance of the being separated by mechanism by wireless network protocol (being such as 802.11) RTS/CTS.Fig. 1 b is the method flow diagram of the adjustment through-put power of the present invention first preferred embodiment.The mechanism of so-called RTS/CTS, namely be that this terminal A first sends RTS (Request to Send) Request Packet before data is transmitted, this terminal B is when receiving this RTS package, this terminal B can send CTS (Clear to Send) package, tell this terminal A to send data and tell that other wireless device during this period of time can not transmit any data, with collision free.
Before being described, first suppose that the multiple different through-put power that this terminal A is sent to this terminal B is divided into three grades (low transmission power grade L1, middle transmit power level L2, large transmission power grade L3).Certainly, other grade can be divided into, not be limited with Three Estate.
In a first embodiment, initially, when this terminal A is not yet familiar with the transmit power level needed for this terminal B, in step 200, in the starting stage (10ms) of this unit interval (1s), this terminal A transmits in regular turn according to multiple different transmit power level and detects the RTS package of package to this terminal B as one, until this terminal B produces the CTS package for responding this terminal A, that is, this terminal A will containing a target location (destination addresses by this communications protocol according to a low transmission power grade L1, this refers to this terminal B) a RTS package of control information (control information) be sent to this terminal B.Now, in step 210, this terminal B is for the receiving power M1 and be preset in a predetermined received power critical value M in this terminal B and carry out judging to determine whether produce from this terminal B the CTS package responding this terminal A of RTS package (through channel attenuation) of this low transmission power grade L1 from this terminal A.If terminal B does not receive the RTS package of this low transmission power grade L1, then surely not produce a CTS package of this terminal A of response.
When this terminal B because this receives power M1 and is no more than this predetermined received power critical value M, and do not produce this CTS package of this terminal A of response.After a scheduled unit time and this terminal A does not receive CTS package, get back in step 200, a RTS package, according to transmit power level L2 in of one-level larger than this low transmission power grade L1, is sent to this terminal B by this communications protocol by this terminal A.Now, in step 210, this terminal B receiving power M2 and this predetermined received power critical value M be preset in this terminal B and carry out judging to determine whether produce from this terminal B the CTS package responding this terminal A for the RTS package (through channel attenuation) from transmit power level L2 in this terminal A.
When this terminal B because receive power M2 corresponding to this of the RTS package of transmit power level L2 in this to be no more than this predetermined received power critical value M, and do not produce this CTS package of this terminal A of response.When after a scheduled unit time and this terminal A does not receive CTS package time, then return in step 200, a RTS package, according to a large transmission power grade L3 of one-level larger than power grade L2 defeated in this, is sent to this terminal B by this communications protocol by this terminal A.Now, in step 210, this terminal B is for the receiving power M3 and this predetermined received power critical value M be preset in this terminal B and carry out judging to determine whether produce from this terminal B the CTS package responding this terminal A of RTS package (through channel attenuation) of this high defeated power grade L3 from this terminal A.
When this terminal B because this receives power M3 and is more than or equal to this predetermined received power critical value M, and produce one the one CTS package of this terminal A of response.One CTS package is transferred into this terminal A by this communications protocol from this terminal B.Ground need be understood; the present invention utilizes IEEE802.11 to use the communication of RTS/CTS package; in transmitting to protect the safety of a data packet; this terminal A transmits a zero data (null data) by this communications protocol, and package is to this terminal B, and this terminal B can return an ACK package (acknowledge packet) to this terminal A after receiving zero data (null data) package.Under this situation, when after this terminal A receives this CTS package and after transmitting this zero data package, this terminal A transmits a detection package to this terminal B in regular turn according to multiple different through-put power again, that is, RTS package again according to a low transmission power grade L1, and is sent to this terminal B by this communications protocol by this terminal A.
One embodiment, this received power critical value M in this terminal B keeps certain.Another embodiment, this terminal B can along with the multiple different transmit power level of terminal A according to this received power critical value M in this terminal B, and the distance of distance between this terminal B and this terminal A and dynamically change the numerical values recited of this received power critical value M, describe based on aforementioned condition, to determine whether produce from this terminal B the CTS package responding this terminal A.
For this terminal B for the tool from this terminal A in this received power M2 of RTS package after channel attenuation of transmit power level L2 be one can received power grade (in other words, M2>=M), this terminal B produces a CTS package of this terminal A of response.Afterwards, this CTS package is transferred into this terminal A by this communications protocol from this terminal B.This terminal A just transmits a zero data (null data) package to this terminal B by this communications protocol after receiving this CTS package.
In starting stage within a unit interval, after the reception of this terminal A transmits this CTS package from this terminal B, step 200 (this terminal A transmits in regular turn according to multiple different through-put power and detects the RTS package of package to this terminal B as one) can be performed constantly, after performing step 200 to step 210, this terminal B judges according to this received power critical value M that this terminal B is predetermined again, to determine whether produce from this terminal B the CTS package responding this terminal A.
After the starting stage (10ms), perform step 220, add up these CTS packages to obtain a statistical value, see form 1.

In a second embodiment, Fig. 2 a and Fig. 2 b is referred to.Wherein Fig. 2 a is within a unit interval, carries out adjusting the schematic diagram of through-put power in a terminal A and the terminal B of a segment distance of the being separated by mechanism by wireless network protocol (being such as 802.11) RTS/CTS.Fig. 2 b is the method flow diagram of the adjustment through-put power of the present invention second preferred embodiment.
Initially, when this terminal A is not yet familiar with the transmit power level needed for this terminal B, in step 300, be in this current unit interval (being such as 1s), this terminal A transmits as detecting a RTS package of package to this terminal B according to multiple different through-put power in regular turn, that is this RTS package, according to a low transmission power grade L1, is sent to this terminal B by this terminal A.Now, in the step 310, this terminal B for the RTS package of this low transmission power grade L1 from this terminal A through received power M1 (the i.e. M1=L1-P of channel attenuation, wherein, P is the power of channel attenuation) be preset in a predetermined received power M in this terminal B and judge, to determine the CTS package whether producing this terminal A of response from this terminal B.
Ground is known by institute, and this terminal B because this receives power M1 and is no more than this predetermined received power M, and does not produce this CTS package of this terminal A of response.After a scheduled unit time and this terminal A does not receive CTS package, get back in step 300, a RTS package, according to transmit power level L2 in of one-level larger than this low transmission power grade L1, is sent to this terminal B by this communications protocol by this terminal A.
Now, in the step 310, this terminal B receives power M2 for one of the RTS package (through channel attenuation) from power grade L2 defeated in this terminal A and judges with this predetermined received power M be preset in this terminal B, to determine whether produce from this terminal B the CTS package responding this terminal A.
IEEE 802.11 is utilized to the communication of RTS/CTS package, in transmitting to protect the safety of a data packet, this terminal A transmits a data packet (data packet) to this terminal B to carry out the transmission of data by this communications protocol.In the third embodiment, can in conjunction with the first embodiment and the second embodiment.Namely add up these CTS package results in this unit interval (1s) in a second embodiment, to determine the through-put power of next unit interval.
Such as: after this current unit interval (1s), add up these CTS packages to obtain a statistical value, see form 2.
Form 2
| Low transmission power grade L1 | Middle transmit power level L2 | Large transmission power grade L3 |
| CTS package: 50 times | CTS package: 1000 times | CTS package: 1500 times |
Perform step 330, judge whether this statistical value is greater than a threshold value, to determine that this terminal A is sent to the multiple different transmit power level of this terminal B within next unit interval (1s).
Such as: this terminal A is analyzed according to the CTS package statistics number in form 2 after this current unit interval, that is the transmit power level corresponding to CTS package of too low number of times is no longer that in next unit interval, this terminal A of training transmits the transmit power level needed for RTS package.In other words, temporarily do not use comparatively can not through-put power.For form 2, due to the number of times of the CTS package of L1 too low (number of times far below other), then do not use L1 in the next unit interval.
Refer to Fig. 3 a, it is the method schematic diagram of the adjustment through-put power of the present invention the 4th preferred embodiment.As shown in Figure 3 a, this terminal A transmits a data packet to this terminal B according to the transmission information form (as shown in Figure 3 b) comprising many group transmission informations, this terminal B determines the response package (confirming that package (acknowledge packet) is for typical example with) whether producing this terminal A of response from this terminal B according to a specific transmission information, the foundation of the selection this data packet being sent to this terminal B as this terminal A preferably transmit power level and transmission rate.
Under WLAN environment, this terminal A and this terminal B carry out Message Transmission by the communications protocol meeting the Institute of Electrical and Electronics Engineers (IEEE) (IEEE) IEEE802.11 wireless network standards.These transmission rate grades in this form meet IEEE802.11 standard, IEEE802.11a standard, IEEE802.11b standard, IEEE802.11g standard, IEEE802.11i standard or IEEE802.11n standard, and these transmission informations in this form adjust according to " automatic rate adjustment (auto-rate fall back) ".
See also Fig. 3 b and Fig. 3 c (this figure is the method flow diagram of the adjustment through-put power of the present invention the 4th preferred embodiment), in step 400, within a current unit interval (2 μ s), this terminal A carries out a data packet transmission according to the transmission information form (as Fig. 3 b) comprising many group transmission informations to this terminal B, wherein often organizes transmission information and comprises a through-put power and a transmission rate.
From this transmission information form, a data packet, with the high transmission speeds in a TRY#1 index and a low transmission power, is sent to this terminal B by this communications protocol by this terminal A.
In step 410, judge at a specific transmission information, whether this terminal B produces response package (in other words, whether this terminal A receives the response package from this terminal B) of this terminal A of response.If after a scheduled time and this terminal A do not receive from this terminal B produce response this terminal A one response package time, then terminal A is according to through-put power in the high transmission speeds and in a TRY#2 index of this form, by this communications protocol, one data packet is sent to this terminal B.So far, if the transmission information in this TRY#2 index is the transmission information of a reception for this terminal B, then by one, this terminal B confirms that package ACK is sent to this terminal A by this communications protocol.Then, this terminal A comes back to step 400.
Ground need be explained, can remain fixing due to this specific transmission information critical value be preset in this terminal B or along with distance between this terminal B and this terminal A or closely and dynamically can change numerical values recited, therefore when this terminal A receive transmit from this terminal B one confirm package ACK after, this terminal A can re-execute step 400 to rapid 410 until after this current unit interval terminates.
