The new MP adjusts its power level in accordance with the allowed power setting information.

Description

Transmit and the received power control method in the network

Technical field

The netted system of the relevant wireless zone of the present invention.Particularly, the relevant signal-sending mechanism that may be implemented on mesh point (MP) with energize transmission (Tx) and the control of reception (Rx) power of the present invention.

Background technology

Fig. 1 shows exemplary wireless system basis construction, comprises one group of access point (AP) that also is called as base station (BS), and each is connected to the wiring network via being called as back haul link (backhaul link) person.This Radio Link system is present between access point and the user station (STAs).In some situations, directly connect given access point to the cost of wiring network system and make alternative more attractive, it is via its contiguous access point of wireless connections and connect access point indirectly to the wiring network.This is called as mesh architecture.Fig. 2 shows that comprising each can support control, manages and operate the simple mesh architecture of a plurality of mesh point of netted service.Mesh point can be and participates in special-purpose basic construction device (as mesh access points (MAP)) or the user's device (as the station) that mesh network is shaped and operates fully.Because it can be to comprise easy use and layout speed so use the advantage of netted basic construction by layout to each access point that wireless network needn't provide back haul link and interconnecting modules.

It is to satisfy the control requirement by control that the delivering power that one extremely important operation consideration is netted node is set.Wireless communication operation system is by FCC (and the adversary in other country) control now.Particularly, specific maximum transmission power setting is designated to minimize the unauthorized wireless equipment interference as the WLAN that is used for most of frequency bands.Moreover these control require to change with every control field (as the U.S., Europe, Japan) usually.(the typical control of the traditional WLAN of basic service sets (BSS) or stand-alone mode (independent basic service group (IBSS)) operation requires system to be summarized as follows (just netted operation is not proposed by this standard of both having deposited) with basic construct pattern.

Different control delivering power permissions during the main system of delivering power control (TPC) under the IEEE 802.11h of 5GHz band radio LAN assigns by European 5GHz frequency band are actuated, but also by the FCC in the different control power requirements of the U.S. at the requirement of 5GHz frequency band, comprise;

Low U-NII (5.25-5.35GHz, 4 channels) U.S. 40mW, European 200mW

Middle U-NII (5.35-5.45GHz, 4 channels) U.S. and European 200mW

(5.47-5.725GHz, 11 channels) only European 1000mW

Last U-NII (5.725-5.825GHz, 5 channels) is U.S. 800mW only

Can to allow delivering power be the Power Limitation information composition (IE) that the control maximum power value from be contained in the national information composition is captured to the maximum at any station in basic service sets or the independent basic service group.Country's control maximum power value (802.11d) is contained in beacon (BEACON) and probe response (PROBE RESPONSE) frame.Similarly, IEEE 802.11h puts into beacon and probe response frames with Power Limitation information composition.

Delivering power control system under the IEEE 802.11h adds the binding requirement (ASSOCIATION REQUESTS) (link and require (RE-ASSOCIATION REQUESTS)) that power-performance information composition to slave station is transferred into access point (or the station in the independent basic service group).This power-performance information composition is that transfer station sets index to the minimum and the maximum possible delivering power of receiving station.

If the scope that is shown in other station power-performance information composition in access point or the independent basic service group does not allow with present basic service sets control setting operation, the binding of being attempted of then standing will be refused by it.Access point is can change in the basic service sets that basic service sets can allow power setting authorities only to be arranged.In the independent basic service group, the station that begins this independent basic service group is to set the person that can allow the power setting, and other station of the propagate beacons frame that continues is to propagate this initial power to set required.

In the basic service sets example, this can allow power setting (skew in control in the national information composition and the Power Limitation information composition) to make change in the basic service sets life period.Scope control and interference reduce is clearly quoted to be used as one of this feature purpose in IEEE 802.11h.Yet, this set these change preferablely should not take place " too frequent ".

Can be used to change power setting even one of this problem is every beacon, ((for example person in packet-switched (PS) pattern) all listens attentively to every beacon frame at also non-all stations.Therefore, it is semi-static sensation that maximum transmission power changes, and it needs some at least target beacon to transmit number of times (TBTTs) (hundreds of millisecond) to make in the basic service sets all stations all be adopted new transmission power setting.

In the official, 802.11h delivering power control system need stand, and inspection can allow power setting when attempting access channel any time.Yet all manufacturers all are automatically updated into its medium access to control tough system open to suspicion from the up-to-date beacon frame that is received.This only takes place reasonable assumption occasionally, only takes place during linking or linking in the extreme example.

802.11h under delivering power control also introduce delivering power control requirements/report (REQUEST/REPORT) action action frame and match.This delivering power control requirements/report action action frame is occupiedly to be used for requiring the delivering power setting to reach link margin from another station.In the delivering power control report action action frame is to be used to transmit delivering power control report person by the report delivering power.By the link margin reported be delivering power control report action action frame when being received by the observed person of receiver.

Being contained in information composition in the delivering power control report action action frame also can be placed at first and proposed in the beacon and probe response of some specific question with the independent basic service group mode by expection.Yet the link margin territory in this example is meaningless and only is set at zero.These new 802.11h delivering power control relevant information compositions are to be found in example 1 frame (just it can be verified and link the station and transmits and receive).

For asking complete, the 802.11h delivering power control function system of 5GHz frequency band draws up amendment by 802.11k " same as before " be extended for 2.4GHz.

For layout and the new layout environments of employing easily easily, be to need netted equipment to adopt the device that allows delivering power to set.Except these control were considered, the accurate system in adaptability delivering power position height can be expected and kept high production and guarantee service quality position standard in the mesh network.

The accurate system that sets in the transmission of the participation node in the network and received power position influences aware communications and interference range greatly.The aware communications scope is that specific data rate can be kept distance point-to-point or the point-to-multipoint transmission.Can not just really be separated Code even the perception interference range is transmission itself, this transmission channel (or even adjacent channel) that still can disturb or demote is gone up other distance of transmitting from other node in the network.

Usually, minimum may the setting by delivering power in the given mesh point of keeping the data rate state of keeping given mesh link, be minimize with network in total channel of other node and the best mode that disturbs in abutting connection with channel.On the other hand, because setting directly influence, the maximum possible delivering power expects signal noise ratio known to the receiver, so this facilitates reportedly transmission rate of high net amount.This means mesh point and faces conflicting requirements and the hobby of representing according to the accurate setting of transmission and received power position of its use.Therefore, the accurate setting in the desirable delivering power position of particular mesh point is indivedual data rates (having the higher data rate that higher transmission power is set) and maximize displacement relation between whole network usefulness (the more spaces on the better performance of the less interference of tool and the same channel utilize again) on the maximization particular link.

The accurate system that sets in received power position of detecting door and minimum reception susceptibility as channel condition assessment (CCA) influences signal noise ratio observed in link budget and the receiver.The accurate carrier wave perception multiple access (CSMA) of setting also influence as 802.11 WLAN in received power position is access of failure channel or the conflict possibility in the base case.

Yet the interference level system of the different node of wireless mesh system institute perception extensively geography changes in time.This is because of dynamic radio environment in the network and transmission real-time time variation characteristic, as the load in every link or path, and the occupied channel time etc.

Therefore, during the thin name of mesh network dynamically the netted node of control transmit and the device system of received power position standard can expect network output and service quality are kept very high and be positioned at guaranteeing on the standard of position.Simultaneously, because must proposing the control requirement, impel based on wireless mesh network channel to change.

Though traditional WLAN (802.11a now, b, g, j, n) do not provide any delivering power that impels employing to begin at first to set, but WLAN medium access control (MAC) and physical layer (PHY) specification are done correction (802.11h) to satisfy the control requirement of European 5GHz frequency band operation.The control of IEEE 802.11h delivering power only makes the WLAN system in the 5GHz frequency band be able to during will entering the initial binding that accounts for and WLAN life period setting delivering power setting (basic construct pattern or simple and easy pattern (AdHoc)) to a certain degree.Yet 802.11h revises and does not propose particular demands and network restriction.This example is not simply expected.

Particularly, there is no the device existence of the selectivity delivering power change of guaranteeing particular link in the network.Moreover only maximum can allow the delivering power setting to be transmitted.Yet, can allow delivering power important as setting as maximum, guarantee link establishment and minimize the minimum power settings of channel access conflict probability also very important.

Variable delivering power is set can improve the wireless efficient of mesh network, but the technology of both having deposited does not provide the method for reaching this characteristic.Moreover the delivering power control method must be designed to make mesh network to be expired then similar operations in the specific control requirement of the 802.11h delivering power control perception of the WLAN now of intrinsic basic construction (in the basic service sets example) and simple and easy pattern (in independent basic service group example).

Summary of the invention

The transmission of the mesh point of a kind of control operation in the meshed wireless communication network of a plurality of mesh point and the method and the device of received power position standard.The power-performance information system of new mesh point is transferred at least one mesh point of both having deposited in this mesh network.This had both been deposited mesh point and can accept this new mesh point and be used as one of this mesh network member, and transmitted and be allowed to power setting information to this new mesh point.This new mesh point is allowed to power setting information according to this and adjusts its power level.

Principal and subordinate's situation system is illustrated in Fig. 4 A and B, is to obtain this information from main power main website from mesh point 101 wherein.Among Fig. 4 A, power main website 101 obtains it in non-request mode from this power main website to allow power setting information 401, as part propagation/multi-point diffusion type frame.Among Fig. 4 B, mesh point 1 obtains it in the request mode as the respond style frame and allows power setting information 403 with responding power performance requirement 402 (requiring/respond style picture format formula as the sensing multi-point diffusion that be can be by switching signal 402,403 between mesh point 101 and power main website).Though Fig. 4 A and B show the permission power setting signal between mesh point 101 and power main website and send that this signal sends and also can distribute situation to be exchanged between mesh point 101 and other vicinity power main website equally.Fig. 4 C and D show the power-performance information interference situation that is exchanged between mesh point 101 shown in similar Fig. 4 A and the B and the mesh point 102.

According to the present invention, request (requirement/Report Type) and non-request receive and allow power setting information 401,403, are can be transmitted to be used as netted multi-point diffusion, the informational content of formula pickaback of multi-point diffusion or propagation management or control frame upper top.Alternative is to allow power setting information 401,403 to be transmitted and be used as independent netted multi-point diffusion, multi-point diffusion or propagation management or control frame.

As netted management frames embodiment, permission power setting information 401,403 signals in the network send and can be included as netted beacon frame or netted probing response frame (as in order to excavate the signal transmit frame and the exchange of mesh network existence or synchronization such as timer value).Alternative is that it is netted binding frame or netted checking frame (exchanging with other mesh point in order to become the mesh network part as frame) that mesh point allows power setting information 401,403.During another substituted, it was that part is pointed to specific purposes and jumped according to every link or multi-hop and allow the power setting frame that bag allows power setting information.

Allow power setting information 401,403 can be alone or in combination anyly to be sent: all netted (effective) as all nodes in the network by signal at following; Specific mesh link or path (effective) as a networking shape node; Specific mesh node (wireless channel as all mesh point is effective); Specific mesh node wave point (as setting the every neighbours of every link and mesh point).

Allow power setting information 401,403 to be sent as absolute value by signal, the relative value relevant with some predetermined absolute value, or definitely reach relative value combination (can allow delivering power=control maximum-temporary transient skew) as maximum.

Turn to Fig. 5, distribute situation to do explanation, wherein there is no the difference that mesh point and mesh point 501 can receive from two or more mesh point that are shown as mesh point 502 and mesh point 503 and allow power setting information with reference now to mesh point 501.Do not have mesh point owing to distribute in the situation, so allow power setting information to other mesh point when setting its self-delivering power setting and sending it, when mesh point 502 and mesh point 503, mesh point 501 must determine it will use the power setting information that how to allow.Signalling procedure shown in Figure 5 can solve the situation how mesh point 501 decisions allow power setting information to use, and allows power setting information and solve to be received from mismatching of other mesh point.

At example shown in Figure 5, its oneself of mesh point 501 configurations allows power setting information A PSI_own, and receives the APSI_i that represents to be sent out from the permission power setting information of MP_i, pointer i=2 and 3.The APSI_i value can represent by vectorial APSI_vector further that its expression mesh point 501 is overall from the APSI_i value that other mesh point receives.

Allow power setting informational content example system to comprise the maximum delivering power that allows and set (MATPS).For simplicity, following method explanation only comprises the maximum delivering power set information composition that allows.When setting its self-delivering power setting and sending permission power setting information to other mesh point, what maximum is mesh point 501 must decide allow the delivering power setting to be used from one group of input MATPS_own504 and MATPS_vector value 505,506.This can reach by the determining function F that implements in the mesh point 501.

For example, suppose that mesh point 501 receives MATPS_vector, comprise two vector value and set 505,506:MATPS_1=20dBM from mesh point 502 and MATPS_1=10dBM from mesh point 503.Also suppose that the setting of the maximum permission of mesh point 501 oneselfs delivering power is configured to MATPS_own=10dBm.In the preferable enforcement, function F will (just min (10 from all its inputs, 20,15)=10dBM) the minimum maximum of decision allows the delivering power setting value, and mesh point 501 lies in and uses the maximum delivering power setting value that allows of computing when setting its delivering power, and it will send it and be used as the permission power setting message part that mesh point 501 is sent to other mesh point.So the maximum permission of the computing delivering power setting of representing with function F 507 is to be expressed as followsin:

MATPS_operational=F (MATPS_own, MATPS_vector equation (1)

＝min(MATPS_own，MATPS_vector)

Similarly, other computational calculation power is set and also can be used suitable function F to select.

In the alternate embodiment, mesh point 501 is that the maximum delivering power setting value that allows of computing that user's formula (1) is determined decides its delivering power, but mesh point 501 sends the maximum delivering power setting value that allows of oneself is used as permission power setting information to other mesh point, mesh point 502 and mesh point 503.

Fig. 6 shows that mesh point 601 enters the signal transmission figure that delivering power wherein is adjusted to satisfy the network 600 of control requirement.Though delivering power is set and adjusted is to do explanation with reference to mesh point 601, identical delivering power setting adjustment program also can be applied to each mesh point in the network 600.Similarly, delivering power can be at netted idea group Be Controlled.Network 600 comprises the mesh point 602-mesh point N that mesh point 601 is sought when entering the mouth.One or more mesh point, mesh point 602-mesh point N can be mesh point.Shown in the 3rd A-D figure, initially added 610 o'clock, mesh point 601 lies in when opening and transmits its delivering power performance information 611 to mesh point 602-mesh point N.As above-mentioned, the preferred mode system of transmission delivering power performance information is as combination or checking (combination or checking more again) frame part.Delivering power performance information 611 can regularly or with request or non-request mode be carried out.In step 612, mesh point 601 becomes the partial mesh system.Mesh point 601 receives the power setting information 613 that allows during lying in and excavating processing or add mesh network, and it is regularly or with non-request or request mode to be transmitted in the network by netted neighbours' mesh point 602-mesh point N.Allow power setting information system as above-mentioned 4A-D figure, to be exchanged.As above-mentioned, this preferred mode system that sends signal uses mesh frame or netted probing response frame.In step 614, mesh point 601 reads this and is received permission power setting information 613 and adjusts its delivering power setting.Mesh point 601 can maybe can not be approved it to other mesh point, and the delivering power of mesh point 602-mesh point N is set and adjusted.

Mesh point 601 can transmit its oneself and allow power setting information 615 to mesh point 602-mesh point N.Similarly, mesh point 601 can receive the delivering power setting changing from the mesh point 602-mesh point N that its delivering power setting changing is touched.It is the power setting that can support to adjust network that some selections and complementary signal send extension (Fig. 6 does not show).For example, mesh point 601 can require the relevant power setting from its mesh point neighbours mesh point 602-mesh point N, and the perceptual signal noise is the link margin value when, the measurement of busy time of perception jamming power and channel.

According to the present invention, option program system is used for negotiating by mesh point and selection power main website.Preferable power main website select and again option program system comprise one or more following persons:

A) first mesh point that belongs in the network becomes the power main website automatically.

Mesh point when b) opening determines whether one of its neighbours are the power main website.System of power main website can receive the L2 or the L3 that are used as part establishing program (as checking, netted beacon receives, function exchange etc.) by mesh point and propagate, and multi-point diffusion or special signal are sent identification.

C) the power main website can be by default (just the netted life-span is for fixing) or binding hours (just special time scheduled volume or dependence particular case take place, and option program system of power main website is restarted).

D) in the favourable enforcement, power main website system is consistent with mesh portal, and mesh portal identifier thereby point to the power main website automatically.

E) mesh point that adjacent web is put maximum links becomes this power main website.

F) mesh point is drawn lots by random number and is decided this power main website.

G) mesh point determines that from mesh portal or specific predetermined mesh point this power main website is the number of hops function.

H) any above combination.

Fig. 7 shows the signal transmission figure that discerns netted power main website according to above-mentioned preferred embodiment.The power main website requires informational content system to be included as by indicating needs to select mesh point to the adjacent web point, the propagation/multi-point diffusion/single-point transmitting signal transmit frame part in the signal 711 that the mesh point 701 of mesh point 702-mesh point N is transmitted via network.This informational content system comprises initiation mesh point address and other parameter, as the time-out value, and selection criterion, the default identifier of proposition mesh point, response address etc.The power main website response message of the propagation/multi-point diffusion in the signal 712/single-point transmitting signal transmit frame partly is via comprising from the adjacent web point, and the network of the selection criterion of mesh point 702-mesh point N response is transmitted.Comparison program 713 lies in the mesh point 701 by initial, wherein from the selection criterion response 712 of different adjacent web points ₁712 _NBe evaluated.It serve as basic the decision that the power main website selects system what mesh point to satisfy the requirement that selected selection criterion pattern represents (drawing lots or similar as the highest random number) with.Mesh point 701 can be propagated it power main website is selected network to the signal 713 at last.

Alternatively be, mesh point 701 can be used as mesh portal, and network is set all delivering powers controls set, and is required to propagate these delivering powers controls and is set to other network mesh point and add mesh point subsequently.

Exchanged between the mesh point or the signal between mesh point and the power main website sends and information is a preferable layer L2 (as medium access control layer) signal transmit frame or the informational content of being implemented as with said method.So, it is the interior processor entity of each mesh point that entity is implemented, as mesh point 101, and mesh point 102 and Fig. 3 A-D, the mesh point shown in Fig. 4 A-D; Mesh point 501 shown in Fig. 5, mesh point 502 and mesh point 503; Mesh point 601 shown in Fig. 6, mesh point 602-mesh point N; And the mesh point 701 shown in Fig. 7, mesh point 702-mesh point N.For example, processor can comprise layer L2 hardware or the software in medium access control or the station administration entity (SME).For example, layer L2 software can be the operation in the mesh point and keeps (Q﹠amp; M) routine part or its combination.Alternative is that signal sends system and is implemented as layer L3 or above signal transmission package or informational content (as being added into Internet protocol packet or transmission control protocol (TCP)/Internet protocol packet etc.).So, entity is implemented to comprise layer a L3 hardware or a software, as Internet protocol or Simple Network Management Protocol (SNMP) entity.Another substitutes and comprises layer L2 and L3 signal transmission combination.
