TECHNICAL FIELD The present invention relates generally to communications, and more specifically, to power control servos. New improved methods and devices for non-servo base stations. Prior art wireless communication systems are widely used to provide various types of communication such as voice and data. These systems are based on code division multiple access (CDMA) and time division labor access. (TDMA), or some other multiplexing access technology. A CDMA system can provide certain advantages over other types of systems, including increased system capabilities. A CDMA system can be designed to support one or more CDMA standards, such as: 200402955 _ (2) Invention description sheet (1) UTIA / EIA-95-B Mobile Station-Base Station Compatibility Standard for Dual-Mode Wideband Spread Spectrum Cellular System "(IS-95 standard); (2) The association unit" 3rd Generation The standards provided by the Partnership Project "(3GPP) are implemented in a set of documents including document case numbers 3G TS 25.211, 3G TS 25.212, 3G TS 25.213, and 3G TS 25.214 (W-CDMA standard); (3) by Standards provided by the association unit "3rd Generation Partnership Project 2" (3GPP2), and in "TR-45.5 Physical Layer Standard for cdma2000 Spread Spectrum S "ystems" (IS-2000 standard) specific implementation; and (4) some other standards. In terms of the above-mentioned named standards, the available spectrum can be shared among many users at the same time, and technologies such as power control and soft handover can be used to maintain sufficient quality to support delay-sensitive servos such as speech. Data services are also available. More specifically, the system has been proposed to improve by using higher order modulations, very fast carrier-to-interference ratio (C / I) feedback from mobile stations, very fast scheduling, and service scheduling with looser latency requirements Data service capabilities. This example of a data-only communication system using these technologies is a high data rate (HDR) that complies with the TIA / EIA / IS-856 standard (IS-856 standard). In contrast to other standards named above, an IS-856 system uses the entire spectrum available in each unit in order to transmit data to a single user at a time, where users are based on link quality and, for example, undecided data. Other considerations to choose. In this regard, when the channel is good, the system will use a high percentage of time for data transmission with a high data rate ', thereby avoiding the resources delivered to support transmission at an insufficient data rate. The net effect is relatively high. 200402955 _ (3) Description of the title page data capacity, higher peak data rate, and higher average throughput. The system may incorporate support for delay sensitive data such as voice channels or data channels supported in the IS-2000 standard and packet data services such as described in the IS-856 standard. -This system is described in a proposal by LG Electronics, LSI Logic, Lucent Technologies, Nortel Networks, QUALCOMM incorporated, and Samsung to the 3rd Generation Partnership Project 2 (3GPP2). The proposal is described in detail in the following documents: On June 11, 2001, 3GPP2 was proposed as document number C50-2001061 1-009, "Updated Joint Physical Layer Proposal for lxEV-DV"; on August 20, 2001, 3GPP2 Proposed as Document Number C50-20010820-012 “Results of L3NQS Simulation Study”; and on August 20, 2001, 3GPP2 was proposed as Document Number C50-20010820-012 “System Simulation Results for the L3NQS Framework Proposal f0r cdma2”. 〇〇1XEV_DV ". For example, these and related documents resulting from the IS-2000 standard revision c including C.S0001.C are hereinafter referred to as the lxEV-DV proposal. For example, the system described in the lxEV-DV proposal usually includes four types of channels: load channels, dynamically changing IS-95 and IS-2000 channels, a forward packet data channel (F-PDCH), and some spare channels. The load channel assignments change very slowly and they will not change for several months. When there are major network construction changes ’they typically change. The dynamically changing 1§_95 and iS_20000 frequencies are configured on a per-call basis, or used for IS-95, or IS_20000 release and 0 to B packet servos. Typically, after loading the channel, the available base station power will be reserved ’and the specified dynamically changing channel is allocated to F-PDch 200402955 _ (4) Description of the title page’ to reserve data services. F-PDCH can be used for data services that are less sensitive to delays, while IS-2000 channels are used for more delay-sensitive services. F_PDCH similar to the IS_856 standard routing channel can be used to transmit data to users in each unit at the highest supported data rate at a time. In IS-856, when transmitting data to the mobile station, the entire power of the base station and the entire space of the Walsh function are available. However, in terms of the proposed ιχΕν-DV system, some base station power and some Walsh functions are allocated to load channels with existing IS-95 and cdma2000 services. After the power of the iS_95 and IS-2000 channels is allocated with the Walsh code, the supported data rate is mainly determined by the available power and the Walsh code. The data transmitted on the F-pDCH is spread using one or more Walsh codes. It is proposed in lxEV-DV that although many users can use the packet service in one unit, the base station can usually transmit to a mobile station on F_pDCH at a time. (Scheduled transmission by two or more users, and appropriate allocation of power and / or Walsh channels to each user, but also to two or more users). The mobile station is selected on the forward link transmission according to some scheduling algorithms. In terms of systems and systems similar to IS · 856 or 1XEV_DV, the schedule is based on channel quality feedback from the servo mobile station. For example, at is_856, the sales desk can evaluate the quality of the forward link and calculate the transmission rate that is expected to be suitable for the current situation.想要 The desired transmission rate from each mobile station is based on the base station. The scheduling algorithm can, for example, select a mobile station for transmission to support the high transmission rate. In order to use the shared communication channel more efficiently. As shown in another example, in terms of the -1XEV_DV system, each mobile station will perform a carrier-interference on the anti-t (5) (5) 200402955 invention description cable channel channel quality indicator channel, bit only rn A LCQICH ( C / I) evaluation is used as the channel quality evaluation value W .... ^ ^ Not suitable. Scheduling the nose is based on the quality of the channel and is used to determine the selection of the station to be used, the subscription station to be lost, and the appropriate transmission rate and transmission format.

The order received the forward link data from a servo base station. As mentioned above, the reverse link feedback from the mobile station to the servo station can be used for forward link scheduling and transmission, and can also be used for servo base station power control. The soft handover of the systems listed above is not used for previous data transmission to the link. That is ... the mobile station will * receive the forward packet data channel, or F-PDCH, from the base station. However, @, a mobile station can soft hand over with one or more non-servo base stations and / or areas on the reverse link to provide the diversity of reverse link changes. Since the path loss characteristics of each path between a mobile station and multiple base stations are usually different, the servo base station power control mechanism used to transmit to the mobile station cannot fit the non-servo base station on the same mobile station. For system capacity optimization, it is desirable that the reverse link and forward link signaling between a mobile station and a non-servo base station be power controlled. However, maintaining a power control loop for each non-servo base station can use excessive resources on the reverse link. Therefore, power control of servo and non-servo base stations is required in the technology. SUMMARY OF THE INVENTION The specific embodiments disclosed herein are needed for power control of servo and non-servo base stations. In one aspect, the power control of a plurality of base stations is 200402955 (6) Description of the Invention The page can be combined 'to form a single command to control a plurality of base stations. In another aspect, the "0ff-up" rule is used to combine power control commands. In still another aspect, a channel quality indicator is used to power control a servo base station. Various other points are also raised. These perspectives have the advantage of providing efficient power control between the mobile station and the servo and non-servo base stations, thus avoiding excessive interference and increasing capacity.

The present invention can provide methods and system elements for implementing various viewpoints, specific embodiments, and features described in further detail below. 1 is a wireless communication system 100 designed to support one or more CDMA standards and / or designs (eg, W-CDMA standard, IS-95 standard, cdma2000 standard, HDR specification, lxEV-DV proposal). Illustration. In another embodiment, the system 100 can also be configured with any wireless standard or design other than a two CDMA system.

For simplicity, the system 100 shown includes base stations 104 interoperating with two mobile stations 106. The base station and its coverage area are often referred to as two "elements". In the IS-95 system, a unit can include one or more fields. In the CDMA regulations, each field and field of a base station The coverage area is called a unit. As used herein, the term "base station," can be used interchangeably with the term access point, or node B. The term "mobile station" can be used interchangeably with the user (UE), subscriber unit, user station, access terminal, remote terminal: other corresponding terms known in the art. The term "mobile a", including fixed Wireless applications. Each mobile station 106 can communicate with one (^ (possibly more)) on the forward link at any time. -11-200402955 Summary of the Invention ⑺ Base station 104 is based on the CDMA system implemented; and Communicate with one or more base stations on the reverse link, depending on whether the mobile station is in-soft handover. The forward link (ie, the downlink) is considered to be from the base station to the mobile station Transmission, and the reverse link (that is, the uplink) is considered-a transmission from the mobile station to the base station. For clarity, the example used to describe the invention is to use the base station as a signal initiator and act Stations are used as receivers and traps for these signals-that is, the signals on the uranium link. Those skilled in the art should understand that mobile stations and base stations can transmit information as described herein, and the point of view of the present invention It can also be used in these cases. The word "example" used herein means "use as an example, illustration, or illustration." The description of any specific embodiment "example" described herein does not necessarily constitute other specific embodiments Better or better. As described, a wireless communication system 100 can support multiple users sharing communication resources such as the IS_95 system at the same time, and can allocate the entire communication resources such as the IS_856 system to one user at a time, or allocate communication resources to allow two types A lxEV-DV system is a system example that separates communication resources between two types of access, and dynamically allocates and allocates according to user requirements. The following is how to configure communication resources for two types of access Brief background of different users accessing the system. Describe the power control that can be accessed by multiple users at the same time, such as IS_95 type channels. The transmission rate determination and scheduling are available for multiple users to share time, such as _IS ^ 856 The data part of the system or a lxEV-DV type system (ie F_pDCH). Note that "external loop" is a term used in the technology related to the two access types, but its meaning is different between the two texts. -12- ( 8) 200402955 Invention description The system capability of the performance page in, for example, the IS-95 CDMA system is partly determined by the interference produced by different users of the system for signal transmission back and forth. The characteristic of a typical CD · system is to encode and modulate the signal transmitted to and from a mobile station, so that the signal can be regarded as interference from other mobile stations. For example, on the forward key path, between -base station and -mobile station The quality of the channel is determined in part by interference from other users. To maintain the difficult and efficient level of communication with the mobile station, the transmission power dedicated to the mobile station must be sufficient to overcome the transmission to other mobile stations served by ill. Power, as well as the agricultural and agricultural reduction experienced on the channel. Therefore, 'to increase the capacity, the minimum power required to transmit each service operation port is desired. A typical CDMA system, when multiple mobile stations transmit to the base The normal power level at the time of the station is to receive multiple mobile station signals at the base station. For example, a reverse link power control system can manage the transmission power of the stations, so that signals from nearby mobile stations carry the mobile station. signal of. In addition to other advantages such as increased talk and pre-use ^ 1 m, reduced battery requirements, etc., when the road is to be effective, 'maintain the transmission power of each mobile station at the minimum power level required to maintain the desired level Standards to allow capacity optimization. Example = -95 A typical CDMA system capability is that interference from other users can be mitigated through the use of power control. Package maximum: Λ i θ The overall efficiency of the system of quality, data rate, and throughput is determined by the user station to be transmitted to maintain possible efficiency. . The result of this is that various power control technologies are in the technology. -13- 200402955 (9) ~~-Summary page of the invention A type of technology including closed-loop power batching can also be configured in the forward link. This is the closed loop power control to determine the target receive power level. = According to the two receiving errors, the error rate can be the target frame error at the desired error rate. When the target transmission power is updated at a low transmission rate, the 相 -phase rate control command occurs relatively frequently, such as = stop. These internal loop power transmission powers are soon suitable to achieve the desired level of u and make the text intrusive ^ 5 tiger and noise and interference ratio. As mentioned above, keeping the transmission and contention of each operation A, and keeping the transmission power of 向 m to the link at = quasi can reduce the interference of other users seen at each mobile station, and allow it to be reserved for other purposes.丁 [汉 ㈣Φ 甘 From transmission power.

In a system such as lxEV-DV, 苴 supports additional ㈣, and the heart's power can be used to increase the rotation amount of the 育 糸 breeding system. As described below, the external control circuit of the power control described above is different from the similarly labeled control circuit that uses only Beco channels.

"Negative material system", or "e.g. data only," for example, lxEV-DV, in a part, a control loop can be configured in a time-sharing manner to control the transmission from the base station to the mobile station. For clarity, the following discussion will describe each transmission to the mobile station. This is an example of different channels from the "simultaneous access system" to distinguish 'e.g. 1s · 95, or at or lxEV_D "system. The two annotations are in this order. Department', 200402955 0〇) I- I mmmw: First, for the sake of clarity, the term "only data" is distinguished from 1s_95 type voice or data channels-the frequency is: As mentioned above, it is obvious to use power control for simultaneous access; only data or data channels are described here; The type of shellfish includes voice (for example, voice over Internet Protocol, or ⑽p). -Any particular usefulness of a particular type of data is determined in part by throughput requirements, delay requirements, etc.孰 == m For various specific embodiments, the majority of any access type and selection is ′ to provide the desired level of delay, throughput, and service quality. Secondly, for example, the system-lean portion of the time-sharing communication resource described by wXEV_DV can simultaneously provide access to more than one user. In the case of Tong Zuo Resources, which provides time-sharing to communicate with a mobile station or user during a certain period of time, 孰 锋 士 # ir caution this technician can adapt to these paradigms to allow shooting and Exceeded—The action producer shared time to and from the transmission. -A typical data communication system includes a variety of different types—or multiple channels. More specifically, one or more data channels are commonly deployed. Although the in-band control signal is included on the -data channel, it is also common for one or more control channels configured. For example, in the __1xev_dv system, a forward packet data control channel (F_PDCCH) and a forward packet data channel PDCH) respectively define control and data transmission on the forward link. FIG. 2 illustrates an example of a mobile station 106 and a base station 104 constructed in a system 100 suitable for data communication. Base station 104 and mobile station 106 are displayed in front of one another: communicating with the reverse link. The mobile station 106 receives the direct link signal at the receiving subsystem 22o. The following base station that communicates with the forward data and control channel -15- 00 00200402955 Description of the title page HM is here regarded as the servo station of the mobile station 106. A receiving subsystem is described in further detail in Figure 3 below. A carrier-interference (C / I) evaluation is achieved when the mobile station-106 receives the forward link signal from the servo base station. A [a measurement is a channel quality metric used as a channel evaluation, and another channel quality degree-quantity is configured in another specific embodiment. The C / I measurement is passed to the transmission subsystem 21 at the base station HM, an example of which is described in further detail in FIG. 3 below. 0-The transmission subsystem 210 transmits the C / I evaluation on the reverse link, where the c / i _ Evaluation is passed to the servo base station. Note that in the well-known soft handover situation in the art, the reverse link signal transmitted from the mobile station is received by one or more base stations other than the servo base station, which is called a non-servo base station. The receiving subsystem 23 of the base station 104 receives C / I information from the mobile station 106. The scheduler 240 at the base station 104 is used to determine whether and how data is transmitted to one or more mobile stations in the area covered by the servo unit. Any type of scheduling algorithm can be configured within the scope of the invention. An example is disclosed in U.S. Patent Application No. 08 / 798,95 1 entitled "METHOD AND AND APPARATUS FOR FORWARD LINK RATE SCHEDULING55" filed on February 11, 1997, which has been assigned to the present invention. In the specific embodiment of lxEV-DV, when the C / I measurement indication received from the mobile station can be transmitted at a certain transmission rate, a mobile station may select for forward link transmission. From the perspective of system capability, select a target The mobile station is advantageous-'so that the shared communication resources can always be used at its maximum supported transmission rate. Therefore, the typical target mobile station selected can be the one with the best report -16- (12) 200402955 Invention Description Sheet C / J. Other factors can also be combined in a schedule decision. For example, the minimum servo guarantee quality has been provided ^ rr ^ a private h u users. With a fairly low report C / W lamp moving table can Select the transmission wheel to maintain a minimum data rate for the user. In the example of the IxEV-DV system, the scheduler 24 can determine the mobile station to be transmitted, the data rate, the modulation format, and the transmission power level. In another implementation such as the IS-856 system In the example, for example, a supported data rate / modulation format decision can be reached on the mobile station based on the channel quality measured on the mobile station, and the magic input format can be transmitted to the base station instead of the C / I measurement. The technician can confirm that the supported data rate, modulation format, power level, etc. can be configured in the scope of the present invention. In addition, although various specific embodiments are described herein, the scheduling work can be performed at the base station, In a specific embodiment, some or all of the scheduling processing may occur at the mobile station. The scheduler 240 may instruct the transmission subsystem 25 to transmit on the forward link using the selected data rate, modulation format, power level, etc. Give the selected action △ In the specific implementation hook, the control channel message or f-pdcch is transmitted with the data on the data channel or F-PDCH. The control channel $ I identifies the data receiving action on the F-PDCH And other useful communication parameters to identify useful during communication connection. When F-PDCCH indicates the target of mobile A 3 transmission, a mobile station should receive and demodulate data from it. The response on the link is the reception of data indicating the success or failure of transmission. The well-known retransmission technology b is commonly deployed in data communication systems. A mobile station can communicate with more than one base station, one of which is known-17 -(13) (13) 200402955 Invention description Soft page handover. Soft handover includes multiple areas from a base station (or a base transceiver subsystem (BTS)) known as soft handoffs, and from multiple areas In the soft handover, the base station area is stored in the active group of the mobile station. In the aspect of sharing communication resource systems at the same time, such as IS_95, IS.2000, and the corresponding part of the 1xEV_dv system, the mobile station can The combination of forward key signals transmitted in all areas of the f active group in the future. In a shell-only system, such as IS_856, or a corresponding part of the system, the mobile port receives a forward link = signal from a base station of the active group servo base station (as described in, for example, the C.s_.c standard Yes-the mobile station chooses the algorithm to be determined). Other forward link signals for the τ plane further detailing the example are also received from non-servo base stations. The reverse link signal from the mobile station is received at multiple base stations, and the quality of the reverse link is usually maintained at the base station of the active group. It is possible to make reverse link signals received on multiple base ports. In general, soft combination of reverse link signals from non-configured base stations will require very small delays = network communication bandwidth 'so the above example system cannot support it. In terms of retransmission, the reverse link signals received on multiple areas of a single BTS can be combined in / out of the network. Although any type of reverse link signal can be configured within the scope of the present invention, in the example system described above, 'reverse link power control can maintain quality, so that the reverse link frame can be Successfully decoded on a BTS (different variation). / In a simultaneous shared communication resource system, such as the lxEV-DV system of the corresponding parts of IS_95, IS_2OO00, 2 and each base that is handed over to a mobile station (that is, the active group in mobile ") The station can measure the reverse link of the mobile station. 200402955 _ (14) The invention describes the pilot quality of the channel and sends out a power control command stream. In IS-95 or IS-2000 Rev. B, if either is specified, each stream will destroy the Forward Basic Principle Channel (F-FCH), or the Forward Exclusive Control Channel (F-DCCH). A mobile station's command stream is called by the mobile station's forward power control subchannel (F-PCSCH). The mobile station receives parallel command streams from all its active group members at each base station (if all are in the active group of the mobile station, the same command will be transmitted to the mobile station from a BTS multi-region) and decides whether to transmit a "Up" or "Down" commands. Therefore, the mobile station can use the "Or-of-downs" rule to modify the reverse link transmission power level, that is, if any "down" command is received, the transmission power level will decrease; otherwise, increase the transmission Power level. The F-PCSCH transmission power level is typically maintained at the level of the main F-FCH or F-DCCH carrying sub-channels. The main F-FCH or F_DCCH transmission power level at the base station is determined on the reverse power control sub-channel (R-PCSCH) through a feedback from the mobile station, which will occupy the reverse pilot frequency channel (R- PICH). Since the F-FCH or F-DCCH from each base station will form a single stream of the routing channel frame, the R-PCSCH can report the combined decoding results of these segments. The erasure of F-FCH or F-DCCH can determine the required Eb / Nt set point of the external loop, which is then driven by the internal loop command on R_PCSCH, so the base station can transmit F-FCH, F-DCCH on them , And F-PCSCH. Due to the potential difference in the reverse link path loss of each base station from a single mobile station during soft handover, some base stations in the active group cannot reliably receive R-PCSCH and cannot properly control F-FCH, F- DCCH, and F--19- (15) 200402955 invention description page == link power. The base stations need to realign the transmission levels among themselves, so the mobile station maintains different gains in the soft handover space. Otherwise ', due to the return from the mobile station & & n, ,, p, ... Bismuth, some forward link segments will reach less or even no routing signal energy. Since different base stations need the same reverse link set point or different mobile stations' transmission power with receiving quality, the power control commands from different base stations can be different and cannot be soft-combined on the milk. When a new member joins the active group (ie, there is no one-way soft handover, or one-way to two-way soft handover, etc.), the F-PCSCH transmission power will be increased along with its main data F_dcch. This may be because when the former has no space difference and load sharing, the latter has more space difference (^ 鲂 φH A, 』J 丨 (total Eb / Nt required for pregnancy) and less energy sharing with the load. ). In contrast, in a 1xEV_DV system, the forward common power control channel (F-CPCCH) can transmit the reverse link of the mobile station without the forward basic principle channel (f_fch) or the forward exclusive control channel (㈣ coffee). Power Control «P 7 In the earlier version of lxEV_DV proposal, it is assumed that the base station transmission power level of F_cpccH is determined by the reverse channel quality indicator channel (R-CQICH) received from the mobile station. Rna CH can use scheduling to reflect forward link channel quality measurements to determine the appropriate forward link transmission format and data rate. However, when the mobile station is in soft handover, R_CQICHR reports the forward link pilot signal in the servo base station area, so it cannot be used to directly control F_CPCCH from the non-servo base station. Various ways to solve this problem are discussed below. An example method is described below: Reverse Link Work -20- (16) (16) 200402955 Invention Description 缜 Page t-rate control 疋 is maintained by all active group members. The mobile station uses the aforementioned f down rule to change the reverse link transmission level. -Is used to power control the base station of the shrine. For example, described further below

Another rule of "Kup" is to use in the mobile station to generate a single power control feedback flow for all non-serving-serving base stations. Θ 疋 For example, a block diagram of a wireless communication device of mobile station 106 or base station J 04 / The block described in this example embodiment is usually a base station-or some of the components included in the mobile port 106. Those skilled in the art will be able to use it for any number of base stations or mobile stations. The embodiment shown in FIG. 3 is constructed.

The signal is received at the antenna 310 and passed to the receiver 32. Receiver 32Q 执 Performs according to one or more wireless system standards such as those listed above: The receiver 320 can perform a variety of different processes, such as radio frequency (RF) band conversion, amplification, analog / digital conversion, wave crossing, etc. . Various different techniques of reception are known in the art. Although a separate channel quality evaluator 335 is discussed in detail below, when the device is a mobile station or base σ day guard, the receiver 32 may be used to measure the channel quality of the forward or reverse link. The number from the receiver 320 is demodulated at the demodulator 325 according to one or more communication standards. In a specific embodiment, a demodulator capable of demodulating ΐχΕν_ DV # #u can be configured. In another specific embodiment, another standard may be supported, and the specific embodiment may support multiple communication modes. _ Demodulation II33G can perform various other functions required for receiving, equalizing, combining, de-interlacing, decoding, and receiving signals. (21) 200402955 (17) Description of the invention title page The same demodulation technology is known in the art. At a base station 1 Q4, the demodulator 325 is demodulated based on the reverse link. In a mobile station, the demodulator 325 is demodulated based on the forward link. The data and control channels described herein are examples of channels that can be received and demodulated in receiver 320 and demodulator 325. The demodulation of the forward data channel occurs in accordance with the transmission of the control channel described above. The Λ-decoder 3 3 0 receives the demodulated data on the forward or reverse link, and captures the signals or messages transmitted to the mobile station 106 or the base station 104. Flood information decoder 330 can decode a variety of different messages, where the message is used to set, maintain, and interrupt a system call (including voice or data connection). The message includes a channel quality indicator for demodulating the forward data channel. No, such as C / I measurements, power control messages, or control channel messages. Various other message types are known in the art and are specified in the various supported standards. The message is passed to the processor for subsequent processing. Although a discontinuous block is discussed for clarity, some or all of the functions of the decoder 330 may be implemented at the processor 350. Alternatively, the second demodulator 325 can decode some information and send it directly to the processing unit 350 (for example, an ACK / NAK single-bit message or a power control increase / decrease command are examples). The quality evaluator 335 is connected to the receiver 32 and is used to make various power level evaluations using the procedures described herein, as well as a variety of other processes for communication, such as demodulation. At a mobile station 100, C / I measurement can be achieved. In addition, the measurement of any signal or channel used in the system can be measured in the channel quality evaluator 335 of a particular embodiment. The following -22- (18) 200402955 Invention description page ==: The power rate control channel is another example. In the -base station_ or the order gate 106, for example, the signal strength evaluation of the receiving clam-crawling power of the grave raft can be achieved. For the sake of discussion, the channel quality evaluator 335 is known to be just a discontinuous block. Usually this block is merged in another block, such as receive write 320 gas demodulator 325. Various types of signal strength assessments can be achieved, depending on the type of signal or system being evaluated. In general, any type of channel quality metric evaluation block may be substituted for the channel Gabe "level estimator 335 configuration within the scope of the present invention. At _base station 1 () 4, the channel quality evaluation is passed to the processor 350 to Using a schedule as described further below, or determining the reverse link quality m, can be used to determine whether to increase or decrease power control. "P" does not need to drive forward or reverse link power to the desired set point. As described above, the desired set point is determined using an external loop power control mechanism. &Quot; The signal is transmitted via the antenna 310. The transmission signal is formatted in the transmitter 37 according to, for example, one or more of the wireless system standards described above. Examples of components included in the transmitter 370 are amplifiers, filters, digital-to-analog (D / A) converters, radio frequency (RF) converters, etc. The transmitted data is provided to the transmitter 37 through the modulator 365 〇. Data and control channels are formatted for transmission according to various formats. The transmission data on the forward link data is based on a data rate and according to a 0/1 or other channel quality measurement. The modulation format indicated by the scheduling algorithm is formatted in the modulator 365. For example, a scheduler of the scheduler 240 is on the processor 35. Similarly, the transmitter 370 may be based on the scheduling algorithm. It is transmitted at a power level. Examples of components incorporated in the modulator 365 include various types of encoders, interleavers, expanders, and modulators of the 23-23200402955 Invention Sheet (19). Message The generator 360 can be used to prepare a variety of different types of messages as described herein. For example, 'C / I messages can be generated on a mobile station for transmission on the reverse link. Various different types of control messages can be on a base station 1 〇4 or action σ 106 is generated for transmission on the forward or reverse link, respectively. The data received and demodulated in the demodulator 325 are passed to the processor 35 used for voice or shell communication. And to various other components. Similarly, data is transmitted from the processor 350 to the modulator 365 and the transmitter 370. For example, various data applications can be used in the processor 350, or in the wireless communication device 104 or 106 ( Not shown in the figure ) Another processor included in the base. The base 1041 is connected to one or more external networks, such as the Internet (not shown in the figure) via other devices not shown in the figure. A mobile station 6 includes, for example, A laptop (not shown) an external device link. The processor 35G can be a general purpose microprocessor, a digital signal processor (DSP), or a special purpose processor. Processor 35 A performs some or all of the functions of receiver 32, demodulator 325, message decoder_, channel quality evaluator, message generator 360, modulator 365, or transmitter 37; and wireless communication devices Any other processing required. Processor features: purpose hardware connection 'to assist in these tasks (details are not in the picture brain or connected to the network, and can be performed on the back of the helmet _ t package ^, or on the processor 350 itself on Bo Er = 35. It is connected to the memory 355 and can be used to store materials: ", to order the different procedures and methods described here. Those skilled in the art-24- (20) (20) 200402955 Invention description can confirm The memory 355 may be composed of various types of one or more memory elements, and may be wholly or partially embedded in the processor 3 $ 0. As described above, in a data system of the example WixEV-DV, the reverse link routes channels It has a high probability of decoding in at least one of these base stations (variation of diversity), and the interference of all reverse links of the base station can be reduced. In addition, the guilty reception of CQICH is in the servo base station which is intended R-cqjch can provide fast forward link channel status update of BTS to efficiently operate F-PDCH. ^ Mobile station can not receive a F_CPCCH earlier from the servo BTS during soft handover, and if The mobile station and the BTS are in soft handover, and this single f_cpcch can be transmitted through more than the servo-only area. This F_cpccH 2 forward link transmission power can be transmitted via the r_cqich from the mobile station through / with external loop circuits Look up to decide (as above Another option for the external loop power control method). When the Tianyan mobile station is a soft handoff between multiple BTSs, there are multiple ways of reverse link power control design. It is close to the description below. ^ One method is from the servo The base station to the mobile station only use a single reverse link power control feedback. For example, when the mobile station is not in soft handover, it can be used. The advantage of this method is that no forward link power or capacity is derived from non-feedback by reference. The F-CPCCHs consumed by the base station. In other words, the non-feeding base station does not control the transmission power of the mobile station. Similarly, the mobile station does not need to measure the forward link measurement except for that. Not on the reverse link: feedback from additional base stations is reached. In addition, there is only one power commander for the mobile station. A major disadvantage of this method is that when imbalance exists between the forward and reverse links-25-200402955 (21), the capacity will be severely reduced. For example, sometimes the reverse link path loss from the mobile station to the non-servo base station will be less than the reverse link path loss from the mobile station to the servo base station When this happens and there is no device to reduce this interference, the non-servo base station has a high degree of interference from the mobile station. Another method is to use the time-division multiplexing R-PCSCH command flow to maintain the response from each active group member BTS. The feedback to the link power control is used for each non-servo BTS. This method can alleviate the forward / reverse link imbalance problem. However, since multiple reverse link feedback signals are time multiplexed, they can The supported data rate can be reduced or the reverse link data rate and interference must be increased. If the symbol is repeated, the transmission power must be maintained at the desired level of R_PCSCH to reach all active group member base stations, and the data rate can be further reduced. . An increase in data rate will require additional reverse link power, which reduces capacity.

Figure 4 illustrates a specific embodiment of a system that uses a first reverse link power control flow to control the servo base station and a second reverse link power control to control a non-servo base station. The mobile station 106 receives a forward link power control flow F_cpccH from each of the active group base stations 104A-104C. In this example, each of the base stations 104a-104C, and then the bS3 includes two areas, respectively, area 2 and area 2, respectively. In this example, the active group includes areas 41OA, 1_2, 41〇B, 1_2, and 410C. Since the mobile station and the multiple base stations (soft) and one or more base stations (softer) are in soft delivery, this is the example of so-called soft_softer delivery. Each active group area can transmit an F_CPCCH to the mobile station 106. The F-CPCCH in the single base two area transmits the same information on the mobile station for combination.的 The reverse link at a base station can be a combined area, so a normal power -26- 200402955 _ (22) Description of the title page Control command flow can be configured in this way. The mobile station 106 provides reverse link power control feedback from each active group member BTS. R-CQICH is used for servo base stations. An opposite power control sub-channel (R-PCSCH) command stream is used to control the non-servo base station. As previously mentioned, each member area in the active group of the mobile station is an F-CPCCH that transmits reverse link power control. Since the non-servo base station cannot infer from the R-CQICH about the forward link condition or the information received by the F-CPCCH at the mobile station, the mobile station can transmit R-PCSCH other than R-CQICH. When the R-CQICH can be used by the servo base station to determine the transmission power level of the F-CPCCH, the R-PCSCH can be used exclusively to carry the F-CPCCH feedback from the non-servo base station. Note that there is only one reverse link power control bit stream from each BTS to the mobile station through all its areas. Likewise, there is no need to provide additional power control feedback from the serving BTS non-servo area F-CPCCH. As shown in the figure, the reverse link reception in the area BTS can be implemented through all areas. Note that Area 2 of BS3 410C, 2 is not in the active group in this example, but R-PCSCH can still be received if needed. FIG. 5 is a flowchart of a specific embodiment of a method for performing reverse link power control. Processing starts at steps 5-10, where each base station in the active group can measure the received reverse link pilot from the mobile station. Go to step 520. In step 520, each area may transmit the F-CPCCH and a power control command generated in response to the measured pilot power. Note that any power control program can be configured to determine power control commands, examples of which are provided above. In another specific embodiment, a signal other than the reverse link pilot may be used for power control. Perform step Midea A. In step 530, the mobile station may receive the power 54540 from the region σ. To control this, execute soft combination. Perform step `` 〇 / Step 540 '' to move the station to change the reverse key transmission power according to the command twns from each base station. Then, the process will stop. This process is typically repeated during each power control group— = 6 describes the timing sequence of reverse link power control. Corresponds to the specific implementation of the system shown in Figure 4 and the implementation example, and the detailed steps of Figure 5 are rounded in the oval using the corresponding step number. It is described in the heart. The reverse link pilot is received at each base ㈣ "BS3. The power control group is labeled G1 + 2 and other base ports. The reverse link pilot can be measured during pcGi as described in step 51." As described in step 52G, each region may then transmit power control commands for the corresponding pilot measurement during its PCGi + 1 on its relative F-CPCCH. As described in step 530, the 'mobile station may send commands from each base station Soft combination. In this example, it is said that the △ ^ JT mobile station can soft combine F_CPCCH from area 丨 and area 2 from BSi, and the soft combination of CPCCH from area i and area 2 from the call. The mobile station can then For example, "~ of-down" s ”rule to determine whether to increase or decrease the transmission power. In this example, the combined command from BS々BS ^ is OR calculated with the command received on the F-CPCCH from the area w. As shown in the figure, the transmission The power is therefore adjusted during PCGi + 2. As described in Figure 5 above, these steps are described in detail in Figure 6 for a cycle, but the process can be repeated every time since the best forward link usually indicates the best reverse link, " 〇r_〇f_

Down "rule can provide proper r_cqich reception on the servo base station. When forward link / reverse link imbalance occurs, that is, the servo base station-28-200402955 _ (24) Invention description If the link is smaller than the reverse link of one of these non-servo base stations, the servo base station can detect the insufficient R-PICH or R-CQICH level as part of its reverse link power control operation. Then, the servo The base station can use F-PDCH or F-CACH to stimulate an R_CQICH repetition feature without more reverse link limit loss. This repetition technique is well known in the technology. Figure 7 depicts a method of forward link power control The flowchart of the specific embodiment. The process starts at step 7100. At step 7100, the mobile station can measure the power of each F-CPCCH from the active group member. In a specific embodiment, the servo base station can be based on the forward direction. The power of the link channel quality control is shown in R-CQICH; thus, F-CPCCH only needs to be measured at the non-servo base station. This is shown in step 720. In another specific embodiment, the power of the servo base station Control can be based on servo The measurement of the base station F-CPCCH is performed. Note that steps 710 and 720 can be performed in any order, or performed in parallel. Step 730 is performed. In step 730, the R-CQICH is transmitted to the servo base station to indicate the front of the servo base station. The measurement quality to the link. R-CQICH can be used for power control. An example is to perform a table lookup as described above. Perform step 7 40. In step 740, a power control command is determined by each non-servo base station. In this example, "Increase" or "Decrease" commands can be generated for each. If there are multiple non-servo base stations in the active group, the mobile station can apply an "Or-of-up" rule 1J to Generate a single command. That is, if any F-CPCCH measurement causes an "increase" command, the power control command will "increase", otherwise the command will be "decrease". As described in Figure 4 above, one or more non-servo base stations The power control command is transmitted on a single R-PCSCH, and the power control -29- (25) (25) 200402955 Invention Description The pagination command can be received by all non-servo base stations. The non-servo base stations can reflect the R-PCSCH Adjust F_ CPCCH (and any other forward link channels as needed). This technology allows non-servo base stations to transmit at a lower level than would be the case with feedback mechanisms. Note that depending on the individual of the non-servo base stations The other logic of the order decision to be transmitted may be used instead of the "0r-of_up" logic. In a specific embodiment, the mobile station may reject signals from non-servo base stations that are deemed insufficient. For example, if a Rake receiver, a limited number of pointers can be used to lock and track non-servo base stations. A common technique is to assign the pointer to the strongest forward link path. In this case, the rake receiver is locked to the most important active group member. "〇r_〇f_ 叩, the rule can be modified to include only non-servo base stations with a predetermined quality level, or a predetermined number of" best, base stations. " These may correspond to the members of the active group with the highest pilot Ec / 10. In addition, as described in Figure 5 above, the reverse link power control rules of "〇r_〇fd〇wns," are essentially limited to the same part of the active group. Since the mobile station considers it too weak, the active group can use Other members, so limiting the “〇 卜 〇f-up” rule to some active group members should not increase the f_ CPCCH bit error rate. Note that usually the weakest reception will determine whether to send an “increase,” or "Reduce, order; therefore, the meta error rate can be kept the lowest among all f-cpcchs. In addition, specific examples can be configured to reduce excessive transmission power that is not the weakest F-CPCCH. For example, the F-CPCCH transmission level can be lower than The better-positioned non-servo base stations are restricted, and their forward link path loss to the mobile station is not the largest. • 30-(26) (26) 200402955 The description of the invention is shown in the separate example. A base station may enable a mobile station to transmit a pilot strength measurement message (PSMM), which is similar to the message in which the forward key pilot quality measured on the mobile station is reported to the base station. From this message, the mobile station ’s Between active group members The forward link path difference can be evaluated. Each non-servo base σ can adjust the transmission level according to its path loss difference related to the maximum forward link path loss. Therefore, it has a better forward link path than the worst. Bit loss: The transmission level from the start of the non-servo base can be reduced by △, where △ is the difference between the path loss of the base station and the path loss of the worst base station (in the active group or a part of it) as described above. When receiving the first or subsequent PSMM, the base station controller (BSC) or other system components can also determine these △ values for various non-servo base stations to be used. An example of this other method is as follows ... Reported from PSMM or other mobile stations, a base station can determine the forward link pilot Ec / i0 value on mobile stations with BS1, BS2, and 883 of -9 dB, -13 dB, and -13 dB, respectively. For this As an example, assume that BS1 is a servo base station. The path loss difference between the worst forward link base station (BS3) is 3 dB. The F-CPCCH reported to BS2 is transmitted to the mobile station's starting transmission level. Then close below the worst base station (B S;) is about 3 dB. So, since the mobile station can measure a similarly received F-CPCCh from or BS3, the unnecessary transmission power from f CPCCH can be eliminated. In another specific embodiment, with the PSMM's Whether it is used or not, each non-servo base station can compete for the relative path loss with the worst base station by measuring the reverse link pilots of other channels. This can be _ part;

Reverse link power control mechanism. Since there is only one transmission from action A Μ σ -31-(27) (27) 200402955 Invention Description The page level and reverse link path loss are likely to be correlated with the forward link path loss, and the base station can find The path loss from the worst base station is poor. The Δ value of the same group can be determined and used. The example of this alternative method is as described above. From the reverse link measurement, the base station can determine the reverse links where BS !, BS2, and BS3 are -21 dB, -22 dB, and _24 dB, respectively. Pilot Ee / (100 + N0) value. In this example, suppose BS! Is a servo base station. The path loss difference between the worst forward link base station ⑺ ^ is 3 dB. The F-CPCCH to the mobile station starts the transmission level and then is about 3 dB below the worst base station (BSs). In this way, since the mobile station can measure the similarly received f_Cpcch from BS2 or BS3, the unnecessary transmission power of F-CPCCH from BS2 can be eliminated. This is referred to the flowchart of FIG. 7. Processing decision block 75 °. In decision block 75 °, '. If the R-PCSCH will repeat, step 760 is performed, and the "0r-0f-up" command is repeated on r_PCSCH for a predetermined number of cycles N. If not, processing will stop. As shown in Figure 5, the process can be repeated for each power control group. The repeating feature of steps 750 and 760 is selective. It may be useful if duplication is necessary to reach all non-servo base stations, where such non-servo base stations may have varying reverse link path losses. Repeating to increase the signal-to-noise ratio is allowed without a corresponding increase in _ transmission power. It may be the case when the reverse link can benefit from duplicates and the forward link _ is also possible. In this case, F-CPCCH can also be repeated. This selectivity is described in further detail in Figure 10 below. As mentioned above, the R_CQICH of the servo base station can also be repeated (not shown in Figure 7), and the corresponding repetition of the servo base station F · CCHCH may be required. This selection is further described in the ητ face Figure 1 () -32- 200402955 (28) Invention description title page Detailed description. FIG. 8 illustrates an example timing diagram of forward key power control. This example is a specific embodiment of the system corresponding to FIG. 4, and the steps detailed in FIG. 7 are described in an oval using the corresponding step numbers. F-CPCCH is transmitted from each active group area. In this example, F-CPCCH is transmitted from areas 1 and 2 of base stations BSj and BS2 and area 1 of base station BS3. The power control group is labeled PCGi, PCGi + 1, PCGi + 2 and so on. During PCGi + 1, the mobile station may measure the forward link pilot and / or F-CPCCHS as described in steps 710 and 720. During PCGi + 2, the mobile station may transmit the R-PCSCH as described in step 740. As described in step 760, it can be repeated as needed. The mobile station also transmits the R-CQICH as described in step 730. These steps are described in detail in Figure 8 in one cycle, but the process can be repeated for each PCG as described in Figure 7 above. In this example, the non-servo base station can reflect the R-CQICH and adjust its forward link transmission power at PCGi + 3. Non-servo base stations can adjust their transmission power based on the R-PCSCH that subsequently receives the R-PCSCH including any repetitive symbols. As mentioned above, in some examples, it is desirable to repeat the R-CQICH with a sufficient signal-to-noise ratio at a particular transmission level. FIG. 9 is a flowchart of a specific embodiment for configuring R-CQICH repetition. Processing starts at step 910, where the servo base station receives R-CQICH in 1 to N time slots, where N is the number of repetitions. If N > 1, the received symbols can be combined. Go to step 920. In step 920, the transmission power level of the servo base station F-CPCCH is set in response to the R-CQICH. Each unique command on the F-CPCCH is transmitted during 1 to N time slots according to the repetition of the R-CQICH. This repetition in R-33-200402955_ (29) Invention Description Continued CQICH and F-CPCCH allow a sufficiently low bit error rate without increasing the transmission power of any channel beyond a desired threshold. In a similar manner, it is desirable in some examples to repeat the R-PCSCH to maintain a sufficient signal-to-noise ratio for a particular transmission level. FIG. 10 is a flowchart of a specific embodiment for configuring R-PCSCH repetition. Processing starts at step 1010, where the servo base station receives the R-PCSCH in 1 to N time slots, where N is the number of repetitions. When N > 1, the symbols can be combined. Go to step 1020. In step 1020, the transmission power level of each non-servo base station F-CPCCH is set in response to the R-PCSCH. Each unique command on the F-CPCCH is transmitted based on the repetition of the R-PCSOH during 1 to N time slots. This repetition allows a sufficiently low bit error rate on R-PCSCH and F-CPCCH without increasing the transmission power of any channel beyond a desired threshold. As described above, in some specific embodiments, when a mobile station is in soft handover, the reverse link power control command from each base station is carried on the relative F-CPCCH channel, but the power control flow is Shipped on F-CPCCH channels with different data rates. For example, among the active group members, there is a serving base station and one or more non-serving base stations. These power control commands can be transmitted via a servo base station at a higher data rate (eg 800 Hz), while power control commands transmitted via a non-servo base station can be repeated one or more times, so they have a lower data Rate (for example, 400 Hz or 200 Hz). In general, each F-CPCCH channel can be transmitted at a data rate. The "Or-of_downs" rule can be modified to account for f-CPCCH channels with different data rates. -34-200402955 Invention description title page (30) Figure 11 illustrates an example of the power control command and F-CPCCH channel system. In this example, the active group size is 3. The power control bits from the servo base station arrive at a data rate of 800 Hz, and the reverse link (RL) power control bits from the two non-servo base stations (non-servo base station 2) are at a data rate of 200 Hz Arrivals. The power control group (pCG) period is labeled n, n + 1, n + 2, and so on. The F_cpcCH from the servo base station is transmitted once per PCG, and each transmission contains a unique value. The mobile station can capture RL power control commands Cn,, c⑴, etc. during continuous PCGs. The F-CPCCH of the non-serving base stations 1 and 2 are also transmitted during each PCG. However, in this example, a value is transmitted in 4 consecutive power control groups. The mobile station can combine the received F_cpcCH values in 4 PCG cycles, and transmit the RL power control command once per PCGs. This allows transmission at a lower data rate; thus, the forward link capability is preserved. The non-servo base station 1 can generate RL power control commands Bn + 3, Bn + 7, and so on. The non-serving base station 2 can generate RL power control commands Dn + 3, Dn + 7, Dn + U, and so on. For example, during power control groups n, n + 1, n + 2, and n + 3, iW-CPCCH symbols from non-feeding base stations can carry the same power control symbol, and the RL power control command Bn + 3 is at PCGn + Capture on the end of 3. In the prior art CDMA system, the power control of different base stations: the decision to reach the mobile station at the same data rate and the order of the output power of one coffee can be determined. That is, if any power control command is reduced by two, it will reduce its transmission power. Only when all the power is controlled ^ 疋 ~ added time 'will the mobile station increase its transmission power. Based on the above-35- (31) (31) 200402955 invention description, the description of the rl power control command is provided. Ci, Bj, and Dk 'mobile stations generated at different frequencies must decide how to adjust its transmission power through response. . When the power control command arrives at a different data rate, the prior art "0. f_ as side ', the rules cannot be applied directly. Various specific embodiments to solve this will be described below. Three-general solutions can be provided as follows : Consider the temple clothing base station, consider the non-civil clothing base station; and the balance between the temple clothing and the non-feeding base station. Please familiarize the technician with these principles to reflect the multiple data rate power control command flow. Various solutions for transmission power control. First, consider the specific embodiment of the servo base station. In this example, the command from the servo base station is used to adjust the power during each session. The command is from-or more During a pcG generated by the non-servo base station, the feeding service and the non-servo base station command are combined with the aforementioned “〇 卜”. ^. _ "Rule. ^ For example, for ^, η + 1, η + 2, η + 4, η + 5, η + 6, η + 8, .... Cl is used to adjust between corresponding PCG ^ RL power. For two n + 7, n + 11, ..., 'Ci, Bi, and Di are combined among the other corresponding GUs using "0r_of_d0wns". When the rl power is affected by the servo base station ratio When the non-feeding base station has more control, this method considers how to serve the base station. Those skilled in the art can clearly understand that the solution just described is just a fan. Any number of base stations can be supported using the power control command flow, and Each stream can be of any data rate. Secondly, consider the specific embodiment of the non-servo base station. As described above, in this example, "all the commands of the servo base station are by using the" 〇r_〇f_ downs "command and Combined with recently received non-feeding base station orders. For example, for h + 3, n + 4, and n + 5, 〇 丨 is the core of the mind. Satoshi, rule -36-200402955 Description of the invention The title page (32) is combined with Bn + 3 and Dn + 3, respectively, to adjust the rl power of the corresponding pCGs. This method considers non-servo base stations when RL power is more controlled by non-servo base stations than by servo base stations. Those skilled in the art can clearly understand that the solution just described is just an example. Any number of base stations can be supported by using power control command streams, and each stream can be at any data rate. Second, consider a number of specific embodiments in which transmission power is controlled in a balanced manner between servo and non-servo base stations. Since commands from servo base stations often arrive more than commands from non-servo base stations, they can be processed differently in order to maintain some balance between servo and non-servo base stations in controlling RL power. Specifically, when the RL power is adjusted in the order from a non-servo base station, the power adjustment may be greater than if the adjustment is based only on commands from the servo base station. A first balanced specific embodiment uses a method similar to the first example, which considers that the aforementioned Serving Base Station only receives commands from the servo base station: during the CGs, the feeding base station command can be used to determine the transmission power Whether f should increase or decrease. However, the step of increasing or decreasing the power change is large, and 帛 -parameters are proportional to ST to achieve. From feed and non-feed bases. During the arrival of the PCGs, the commands from the servo and non-feeding base stations can be combined (using the “0r_〇f_d〇Wns” rule to open) into a combined command. The increase or decrease decision can be achieved by using "0r_〇f_d〇wns," a rule on the Serving Base Station Command and Combination Order. When the combined command is in opposition to the feeding base station command, the power can be compared with the number of H Proportionally, = or decrease steps to adjust. When the combined command is different from the verbal command, the power can be increased or decreased in proportion to the third parameter -37- 200402955 (33) I Invented Describes the cable sheet with few steps to adjust.

In the example of FIG. 11, due to the relevant frequency of the command stream, the second parameter can be set to 4 * ST, and the third parameter can be set to 3 * ST. This example can be extended to power control command streams at any data rate. In general, when the data rate between the servo base station data rate and one or more non-servo base stations is K (K21), the second parameter can be set to K * ST, and the third parameter can be set to ( K-1) * ST. A second balanced embodiment also uses a method similar to the first example, which considers the aforementioned servo base station. As mentioned before, during the PCGs only receiving commands from the servo base station, the servo base station command is used to determine whether the transmission power should be increased or decreased. Moreover, the step of increasing or decreasing the power change is achieved in proportion to a first parameter ST. During PCGs arriving from servo and non-servo base station commands, non-servo base station commands can be combined (using the "Or-of-downs" rule) to form a combined command. The increase or decrease can be achieved by using the "〇r_〇f_ downs" rule on the servo base station commands and combined commands. In this example, the combined command and servo base station command are a weighted combination to form a metric M. The power is adjusted using an increase or decrease step size that is proportional to a second parameter, as calculated by 乂 ^ 丁.

As shown in Fig. 11, by using the relative frequency of the command stream, the metric M can be calculated as follows. A + 1 is a designation increase command, and a-1 is a designation decrease command (those skilled in the art can confirm that these values are just examples). The combined command ("Or-of-downs" of the non-serving base station) is multiplied by 4 and added to the sum of the four previous commands from the servo base station to form the metric M.
