Description

201004170 VI. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a wireless area mesh system. In particular, the present invention relates to a signal transmitting mechanism that can be implemented at a mesh point (MP) to enable transmission (Τχ) and reception (operation) power control. [Prior Art] The brother 1 shows a typical wireless system infrastructure. The packet-group is also called the base station (BS) access point (ΑΡ). Each is called a backhaul link. Connected to the wiring network. The wireless link exists between the access point and the subscriber stations (STAs). In some scenarios, the cost of directly connecting a given access point to the wiring network makes the alternative more attractive by indirectly connecting the access point to the wiring network via wirelessly connecting its neighboring access points. This is called a mesh architecture. Figure 2 shows a simple mesh architecture with multiple mesh points that support the control, management, and operation of mesh services. The mesh point can be a dedicated infrastructure (such as a mesh access point (MAP)) or a user device (such as a station) that is fully involved in the shaping and operation of the mesh network. Because the wireless network does not have to provide bribe scales and interdependencies for each access point to be laid out, the advantages of the = mesh infrastructure are easy to use and layout speed. - Very, the transmission power setting to be considered for the operation of the system node is regulated to meet regulatory requirements. Today's wireless communication operations are regulated by the FCC (and its competitors in other countries). The system is that the maximum transmission setting is 曰疋, the most jest, such as unlicensed wireless interference in the wireless local area network for most frequency bands. Furthermore, these regulatory requirements typically change with each regulatory area (eg, US, Japan). The typical regulatory requirements for traditional wireless LANs operating in the basic construction model (Basic Service Group (BSS) 3 201004170 or Standalone Mode (Independent Basic Service Group (IBSS)) are summarized as follows (ie, mesh operations are not retained by this) The standard proposed. The transmission power control (TPC) under IEEE 802.11h in the 5 GHz band wireless local area network is mainly driven by the different regulatory transmission power grants in the European 5 GHz band assignment, but it is also regulated by different US power requirements. The FCC targets the 5GHz band and includes: Γ) • Low U-NII (5.25-5.35GHz, 4 channels) US 40mW, Europe

200mW

• Medium U-NII (5.35-5.45GHz, channel 4) US and Europe 200mW. (5.47-5.725GHz, channel 11) only Europe lOOOOmW • Upper U-NII (5.725-5.825GHz, channel 5) US 800mW only

The maximum allowable transmit power of any station in a basic service group or an independent basic service group is the power limit information component (IE) that is extracted from the regulated maximum power value included in the national information component. The nationally regulated maximum power value I (802.11 d) is included in the beacon (BEEACON) and probe response (PROBE RESPONSE) frames. Similarly, IEEE 802.11h puts the power-limiting information component into the beacon and probe response frames. The transmit power control under IEEE 802.11h adds the power performance information component to the ASSOCIATION REQUESTS (RE_ASSOCIATION REQUESTS) that the slave station transmits to the access point (or the station in the independent basic service group). . This power performance information component is an indicator of the minimum and maximum possible transmission power of the transmitting station to the receiving station. If the other station power is marked in the access point or in the independent basic service group 4 201004170 = The component k is not allowed to be set by the target service control. The access point is the only authority that can change iiiT" to allow for the identification of basic services. ^ In the basic service group, the station that starts the independent basic service group is set to two powers, and the other stations that follow the health message frame are required to transmit the initial power setting. . However, the setting of these changes may be changed during the life of the basic service group as compared to the basic power service's allowable power setting (10) offset in the official and power limiting information components of the transcoding component. The range control is like the interference reduction. It is considered to be one of the characteristics in ΙΕΕΕ 8〇2.11h. It should not happen “too frequent”.

One of the problems is that even if each beacon can be used to change the power setting, not all stations (such as those in the packet switching (PS) mode) listen to each beacon frame. Therefore, the maximum transmission power change is half. Static feeling, which requires at least a number of target beacon transmission times (TBTTs) (hundreds of milliseconds) to enable all stations in the basic service group to adopt the new transmission power setting. Lu Fang's '802.1 lh transmission power control system needs to stand at any time to try Check the allowable power setting when accessing the channel. However, all manufacturers have automatically updated the latest received beacon frame to its media access control tough system. It is reasonable to assume that this happens only occasionally, in extreme cases only This occurs during the connection or reconnection. The transmit power control under 802.1 lh also introduces the transmit power control request/report (REQUEST/REPORT) action frame pairing. This transmit power control request/report action frame is occupied to require transmit power. Set and the link tolerance from the other 5 stations. The reported transmit power in the transmit power control report action frame is used to transmit the transmit power control. The link tolerance is transmitted by the receiver when receiving the transfer control action. The information component included in the transmission power control report action frame can also be placed in the most reduced position. The unique domain of the _ formula proposes beacons and probe responses for certain special problems. _, the link tolerance domain in this example is meaningless and only mosquitoes are zero. These new 8G2 llh transmit power control related information components Was gambling by Wei _ 1 (also transmitted and received by Qianling County Linxun and unconnected stations). In order to complete the '5 GHz (4) 802.Uh transmission power control function is drafted by 802.11k, as it is, It has been expanded to 2 4 GHz. In order to cover the secrets of Wei Si, the mesh-type equipment adopts a device that allows transmission and setting. In addition to these financial resources, the adaptive transmission system can be highly converted to high-yield. The service quality level in the road. The transmission and reception power levels of the participating nodes in the mesh system greatly affect the age and interference. The perception of the wire is the transmission of the specific data rate to the point of riding or multi-point transmission. Broadcast range is even if the wheel is Verifying the cipher code, the transmission can still degrade the channel (or even proximity to other distances from other parts of the mesh system that are transmitting. One ''usually' maintains the given maintenance of the given mesh link: # The most expensive scale in the mesh point is sent to the god mosquito, which is the minimum tilt == 201004170 The best way for other nodes in the system to share the channel and adjacent channel interference. On the other hand, because the maximum possible transmission power setting directly affects the intended receiver Knowing the signal-to-noise ratio, this contributes to a high net data transfer rate. This means that the mesh point faces conflicting needs and preferences based on the transmit and receive power level settings used by it. Therefore, the ideal transfer of a particular mesh point The power level setting is to maximize the individual data rate on a particular link (higher data rate with higher transmit power setting) and maximize the performance of all mesh systems (with better performance with less interference and on the same channel) More space reuse) the replacement relationship between. For example, the CSA detection threshold and the minimum reception sensitivity of the received power level setting affect the link budget and the observed signal noise ratio in the receiver. The receive power level setting also affects the probability of failed channel access or collision in a carrier-aware multiple access (CSMA) based scheme such as the 8〇211 wireless local area network. However, the interference level perceived by different nodes of the wireless mesh system can be geographically timely and timely. Lin _ _ _ _ wireless environment and transmission of real-time time characteristics, such as the load per link or path, occupy channel time. Therefore, the device of the mesh network thin-skinned mask control network node transmission and receiving power = level is available for the network of secret output and service quality guarantee = very second and located at the level of insurance. At the same time, because the wireless mesh network must make regulatory requirements, it will cause channel changes. Although today's traditional wireless local area network (10) 2 does not provide any transmission power setting that is initially used, it corrects the wireless area network 7 201004170 media access control (MAC) and physical layer (ρΗγ) specifications (8). 〇 2iih) to meet regulatory requirements for European 5 GHz band operation. The 8 ziih transmit power control only allows the wireless local area network system in the 5 GHz band to enter the reduced connection and set the transmission power slave during the lifetime of the wireless area (Basic_Material) . However, the 802.11h fix does not address specific requirements and mesh system limitations. This case was not expected as early as possible. In particular, there is no device that ensures a selective transmission rate change for a particular link within the mesh system. Furthermore, only the maximum allowable transmit power setting can be transmitted. _ 'As important as the maximum allowable transmission god setting, the minimum power setting for the sister link establishment and the minimum axis access collision probability is also important. The variable transmit power setting improves the wireless efficiency of the mesh network, but existing technologies do not provide a means to achieve this. Furthermore, the transmission power control method must be expected to make the __ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The specific regulatory requirements for transmitting power control awareness.

(For example, 802.11η supports 10/20/40MHZ bandwidth, while j〇2·1 lj supports 1 〇 or 20MHz bandwidth.) The number of bands and sub-bands that the mesh point can operate simultaneously (eg 2.4GHz, 5 GHz, 5 GHz) Low U-NII, 5 GHz U-ΝΠ)_ In Figure 3, the mesh point 1〇1 reports its divinity in an unsolicited manner such as the partial propagation/multicast type frame (4) Xie Xie to the power master station . In Figure 3B, the mesh point 1 reports its power performance information 3〇3 in response to the request of the response type frame in response to the power performance requirement (eg, the exchanged signal 3〇2 '303 can be the mesh point 1〇1) And the multi-point propagation request/response type frame type between the power master stations). Although the 3A&B diagram shows the power performance between the mesh point and the power master station, the bribe number can also be exchanged between the mesh point 101 and other nearby power stations. The first redundancy and the D ugly are similar to the signal transmission diagrams of the mesh performance point (9) and the mesh point 1〇2 shown in the 3A and B diagrams, which are replaced by the power performance information interference situation of the parent. According to the present invention, the request issued by the feeding (recording type) is reported to report the power performance information 3〇1, 303, which can be transmitted as: multi-cast, multicast, or communication management or control匡上上的机械分.

The 4A and B pictures of the Kangmu key show the main network point to know the allowable power setting:: Figure 'The network point is used to handle the communication period does not exceed the specific maximum: the definition of the slave.

In the 4A picture, the ^-point 101 is in the alpha music diagram, the power master station 101 is from the non-printing mode. The power master obtains its 401, such as partial propagation 1 to the requester, such as the requester, to allow the transfer to be set to m 403 in response to the power performance requirement (eg, the exchanged signal 402, 403 can be == power master) The point-to-multipoint request/response type signal Although the 4A&B picture shows the mesh point 101 and the power master station = the trousers setting signal is sent, but the money can also be sent to the brother to be replaced by the father. Point 101 and other adjacent power masters Between the stations, the first and fourth pictures are not similar to the power performance information interference situation exchanged between the mesh point 1 (1) and the mesh point point shown in Figure 4A & B. According to this (4), the request (request / report _ The scale request accepts the allowable force rate sigh bfL he's 403, can be transmitted as a mesh multi-cast, multi-point or _ management on the top of the box on the top of the shooting information component.

For example, the mesh management frame embodiment, the power setting information 401 in the mesh system '4G3 money transmission can be included as a bet bet or a mesh detection response frame (such as to send a bet and exchange in order to explore the presence or synchronization of the mesh network). Yes, the network point allows the power setting information 4〇1,4〇3 is the mesh link frame or the mesh verification frame (if the frame is 13 201004170 part and exchange with other mesh points). In addition - in the alternative, multi-hop allows for transpose _.

All (such as the network _ oblique all axis link or path _ node is valid); Node

The wireless channel with difficulty is effective); the wireless interface of the mesh node (such as each link and each neighbor of the mesh point can be set). Allowing the power setting information to tear, 4G3 can be signaled as an absolute value, combined with some predetermined absolute value of the dragon's side, or a combination of the sum of the values (such as maximum allowable transmission power = control maximum temporary offset). Turning to Figure 5, the assignment context is now described with reference to the mesh point 5〇1, where there is no mesh point and the mesh point 5()1 can be received from the displayed mesh point 502 and the mesh point 5〇3 The difference in two or more mesh points allows power setting information. Since there is no mesh point in the distribution context, when setting its self-transmitting power setting and transmitting its allowed power setting information to other mesh points, mesh point 502 and mesh point 503, the mesh point 501 must decide that it will use How to allow power setting information. The signal transmitting program shown in Fig. 5 can solve the problem that the mesh point 501 determines the allowable power setting information to be used, and solves the mismatch allowable power setting information received from other mesh points. For the example shown in Fig. 5, the mesh point 501 is configured with the self-allowed power setting information APSI_own, and receives the APSI_i indicating the allowable power setting information transmitted from the MP_i, the indicators i = 2 and 3. The APSI_i value can be further represented by a vector APSIjvector, which represents the population of APSI_i values received by the mesh point 501 from other mesh 201004170 points. The Allow Power Set Information component example contains the Maximum Allowable Transfer Power Setting (MATPS). For the sake of simplicity, the following method description contains only the maximum allowable transmit power setting information component. When setting its self-transmitting power setting and transmitting the allowed power setting information to other mesh points, the mesh point 501 must determine from a set of input MATPS__own 504 and MATPS_vector values 505, 506 what maximum allowed transmit power setting will be used. This can be achieved by implementing the decision function F in the mesh point 501. For example, assume that mesh point 501 receives MATPS_vector, including a two-way value setting 505, 506: MATPS - 1 = 20dBM from mesh point 502 and MATPS_l = 10dBM from mesh point 503. It is also assumed that the mesh point 501 self maximum allowable transmission power setting is configured as MATPS_own = 10 dBm. In a preferred implementation, the function f will determine the minimum maximum allowable transmit power setting from all its inputs (i.e., min(l 〇, 20 ' 15) = l 〇 dBM), while the mesh point 501 is set to set its transmit power. The maximum allowable transmit power setpoint is calculated using the operation, and it will send it as the mesh point 5〇1 to the allowable power setting information portion of the other mesh points. Thus, the maximum allowable transmit power setting 507 represented by the function F can be expressed as follows: MATPS_operational = F(MATPS_own, MATPS_vector) Equation (1) = min(MATPS_own, MATPS vector) Similarly, other operational power Settings can also be selected using the appropriate function F. In an alternative embodiment, the mesh point 501 is determined by the equation (1). 15 201004170 = to = I am the most 疋 讯 讯 至 to his eight mesh point, the mesh point 5 〇 2 and the mesh point.

The 疋 疋 相 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Likewise, the transmit power can be controlled for a subset of mesh points. The mesh system 600 includes a mesh point 6〇2' mesh point n when the mesh point 601 looks for an entrance. One or more mesh points 'mesh point 602 - mesh point N may be a mesh point. As shown in Fig. 38, the 'initial addition 610' mesh point 601 transmits its transmission power performance information 611 to the mesh point 6〇2' mesh point N when it is turned on. As mentioned above, the transmission power (4) is compared with the financial thread as a part of the joint certificate (recombination or re-verification). Transmit power performance information 611 can be performed periodically or in a request or unsolicited manner. At step 612, the mesh point 601 becomes a partial mesh system. The mesh point 601 is for receiving the allowed power setting information 613 during the excavation process or joining the mesh network, which is transmitted by the mesh neighbor mesh point 6〇2_ the mesh point N periodically or in an unsolicited or requested manner. In the mesh system. The allowable power setting information is exchanged as in the above 4A_D diagram. The preferred way of transmitting the signal as described above is to use a mesh frame or a mesh detection response frame. At step 614, the mesh point 601 reads the received allowable power setting information 613 and adjusts its transmit power setting. The mesh point 6〇1 may or may not recognize its transmission power setting adjustment for other mesh points 'mesh point 602-mesh point N. 16 201004170 The mesh point 601 can transmit its self-allowed power setting information 6i5 to the mesh point N.

According to the invention, the selection process is networked to the selected master station. The preferred power master selection and reselection procedure includes a private and eve: a) the first mesh point in the mesh system automatically becomes the power master. b) When opening, the point is determined by its neighbors - whether it is the power master: = 彳 峨 峨 is used as part of the establishment procedure (such as the test broadcast or exclusive to the county _. # power ^ station can be preset (that is The mesh life is fixed or limited (that is, the predetermined time or specific time depends on the specific situation, the power master selection procedure is restarted).

The primary station is a jump number function. 17 201004170 h) Any combination of the above. Figure 7 is a diagram showing the signal transmission of the mesh power master station in accordance with the preferred embodiment described above. The power master requires that the information component be included in the signal 711 transmitted by the mesh system via the mesh system by indicating that the mesh point is selected to the adjacent mesh point, and the mesh point 701 of the mesh point 7〇2_ mesh point N is transmitted. Propagation/multicast/unicast signal transmission frame part. This information component contains the originating mesh point address and other parameters, such as the pause value, selection criteria, the default identifier of the mesh point, the response address, and so on. The power master station response information portion of the signal transmission 712 propagation/multicast/single-point transmission signal frame is transmitted via a selection criterion containing a selection criterion from the neighboring mesh point, the mesh point 7〇2_the mesh point N. The system is transmitted. The comparison program 713 is initiated in the mesh point 7 () 1 where the selection criteria response 712 from the different adjacent mesh points is evaluated. The choice of the power line is based on the choice of the type of choice, and the type of representation (such as the highest random number lottery or similar) is determined. The mesh point 7〇1 can propagate its mesh system that was last selected into the signal 713 for the power master. j substitution is 'mesh point 7 (1) can be regarded as a mesh entrance, and the mesh system hits #疋户f has a transmission power control setting' and then the added network point is to be broadcasted and not transferred to the god butterfly set to other Secret network points. The method of the scholarship is exchanged between the mesh points or the mesh point and the power main station. The developed and information system is preferably implemented as a layer L2 (such as the media access control layer) Qian Wei Bri or: New Zealand The mesh point shown in the 4A-D diagram, the net 18 shown in Fig. 5 201004170, the point 501 'the mesh point 502 and the mesh point 5〇3; the mesh point 601 shown in Fig. 6 , the mesh point 6〇2_the mesh point N; and the mesh point 7〇1 'the mesh point 702_the mesh point N shown in FIG. For example, the processor may include layer L2 hardware or software in a media access control or station management entity (SME). For example, the layer L2 software can be the operation and maintenance (Q&M) routine portion of the mesh point or its group. Alternatively, the signaling system is implemented as a layer L3 or above signaling packet or information component (e.g., added to an internet protocol packet or transmission control protocol (tcp)/internet protocol packet, etc.). As such, the entity implementation can include layer L3 hardware or software, such as an Internet Protocol or Simple Network Management Protocol (SNMP) entity. Another alternative includes layer L2 and L3 signaling combinations. All signal transmission messages and information exchanged as described above can be directed to the chain, , and . (such as mesh point-mesh point signal transmission frame) or multi-hop frame signal transmission (for example, the mesh point transmits the message to another mesh point via the intermediate transfer network point). Furthermore, signal transmission can occur between the mesh point in the wiring backhaul and another node. All of the above methods can accept or be complementary to the configuration settings in each mesh point, and can provide statistics and feedback to the internal mesh or external network monitoring and control entities that can be moved to the mesh point operating characteristics (if used) The remote Ting administrator network monitors the dumping. These configuration slaves and reportable volumes can be initiated or reported from each (group) mesh point by the following format or combination: a) The physical layer, the media access control or the database in the station management entity can be advantageous The ground is implemented (but not limited to) as a Management Information Base (Mffis) type; b) Sends a message between Layer 2 Media Access Control or Station Management Entity that is advantageously implemented as an Application Programming Interface (AH) to the above agreement Real 19 201004170

C) The primitives are exchanged between the station management entity, the media access control, the physical layer and other agreed entities in the implementation of the mesh point. The above configuration settings that can be used by an external management entity on a mesh point (or group of mesh points) can include any of the following: a) allowable transmission, reception, and channel condition evaluation value settings and ranges; b) allowable Mode settings (such as na, b, g, j, n, etc.);
