TW201206095A - Soft handoff of a CDMA reverse link - Google Patents

Abstract

Method and apparatus for base stations and subscriber units allows soft handoff of a CDMA reverse link utilizing an orthogonal channel structure. Subscriber units transmit an orthogonally coded signal over a reverse link to the base stations. A given base station provides timing control of the timing offset of the reverse link signal. Based on at least one criterion, an alignment controller determines that the given base station should hand off timing control to another base station, and a soft handoff process ensues. In response to a command or message for soft handoff of the subscriber unit from the given base station to another station, the subscriber unit makes a coarse timing adjustment to the timing of the coded signal. The subscriber unit may make fine timing adjustments based on feedback from the base station controlling timing. Multiple base stations may provide power control feedback to the subscriber unit.

Description

201206095 VI. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates generally to communication networks, and more particularly to soft handover operations for coded multiple access reverse links. [Prior Art] The form and demand of wireless communication services have grown unprecedentedly in the last two decades. Wireless voice communication services, including mobile phones, personal communication services (PCS) and class-like systems, now offer almost everywhere coverage. The infrastructure used for such networks has been established as the majority of residents in the United States, Europe, and other industrialized regions of the world with more than one ‘and multiple service providers to choose from. The continued growth in the electronics and computer industries is a contribution to the increased demand for access to the Internet and countless services and features offered. The use of computing devices including laptops, handheld personal digital assistants, Internet-enabled mobile phones and similar devices, especially portable types, has increased the demand for wireless data access. . Although mobile phones and personal communication service networks are widely deployed, these systems are not intended to be used to carry streaming information. Instead, these systems are designed to efficiently support continuous similar messages 201206095, compared to the burst mode digital communication protocol required for Internet communication. It is also considered that the voice communication system is suitable for a communication channel bandwidth of about 3 kilohertz. However, for Internet communications such as Internet Explorer, a data rate of at least 56,000 bits per second is acceptable. ' '' In addition, the nature of the flow of the poor stream itself is different from the nature of voice communication. The voice system requires a continuous multiplex connection; that is, the user of the ::link-end is expected to be able to continuously transmit the user at the other end and receive it by the user. Taking web pages - in general terms - is very straightforward. Typically, the user of a remote client computer has the address of a computer slot on a network server. : The ground is formatted as a fairly short data message, typically ί is less than 1 0 0 0 bytes. Then, the other end of the link, such as the network, responds with the requested data file. Due to the inherent nature of the delay of the Internet itself, the content of :: 4 begins to be transmitted to the user more in the break. Then, the content is transmitted / "delayed for at least a few seconds or 3 - the time before the page is downloaded: seconds: to view or read the contents of the page. The second or even a few minutes, :f 'Voice network is built to support the form of high mobility. "Use the length of ί long to support the speed of the highway, for voice-based actions and individuals. Communication 8 201206095 The user of the service network maintains a link when moving along a highway at high speed. However, the typical user of a laptop is quite static, such as sitting at a desk. Therefore, for wireless Voice Considerations The important point of action of the mobile unit on the high-speed mobility of the mobile unit is typically not required to support data access. [Summary] Improving some of the components of the existing hotline infrastructure to more efficiently fit wireless data It is meaningful. The additional work of implementing a new user level for users with high data rate 1 low mobility should be backwards and compatible with the functions currently used for low data rates and high mobility. This will allow Use the same frequency allocation plan, base station antenna, construction location, and other aspects of the existing voice network infrastructure to provide new High-speed data service. The reverse path of such a network carrying data on the reverse link supports the highest possible data rate, such as from the remote unit to the base station. Coca-Chan 1 τ to 芩If the responder is 1S_95 coded multiple access (Code DlvlsiGn chest sound - (10), cdm bit action is specified in a sequence of the forward chain to save, to maintain the channel door hang up using different code sequences 乍 颏The small interference between the two is clear. In a word, a system uses a gift such as i Luo Fufu, sound # father code on the forward link, which defines individual avoidance frequencies. However, so this is the case, ^ this The best operation of the system requires that all of the I1s are time-aligned to the -specific boundary so that the connection is positive. Therefore, the transmission must be synchronized. This is not a forward link. A special consideration, because 201206095 = some transmission systems originated from the same location, that is, in the location of a base station. However, the current digital code division multi-channel access standard system, no Attempt to use or need to be in the reverse link direction Orthogonality between 迢. In general, it is assumed that the synchronization origin = in: a plurality of remote units in the same position and the transmission system at different distances from the moon can be difficult. The ground system has this long pseudo with ^

The wafer level (4) is used to identify the individual reverse key frequency H, and the use of this garbled code eliminates the possibility of orthogonality with each other. Therefore, a first group of users of one embodiment of the present invention: package 3; a type of correspondent that supports the user's components:: group The user of the first group of users who have been used by the user is a common first code. Provided by one for each:::: = only - _ == _ one of the code phase offsets of the two and the: phase: the code and each of the users of the group", Transmission. However, the second code is transmitted, the additional code; in the first step, an additional code is used to encode a system as a unique-dip; the brother-group user is orthogonal to each other, and at the same time = the second is allowed The transmission of a short group of users - the user::, to maintain the overall appearance of the first group - 201206095 refers to S, to the users of the first group: the rate of capture or random code m The first co-author's horse is typically the individual component of the terminal that can be used as a 'group unique Π-group. The first group selects a longer pseudo-p嫉, although the error has a coded offset and is recognized as a column-only phase offset in a preferred embodiment for the second group of users. The two of the messages are indeed: The second is clear that 'a common Ma channel system is used as a synchronization, field to tie the encoding mechanism to a counter. For example, it is possible to maintain the correct timing of the transmission in the direction of the =1-th key direction and the transmission of the terminal of the group. In another embodiment, the __ is / is assigned to the specific time slot of the transmission: ::: dimension to be orthogonal .... ground, : two:::: two t in the first, the user's Transmission performance is the principle of the invention that allows for the design of traffic workers: the current code division multiple access system supports the soft handover operation of the orthogonal channel users on its reverse link to increase The resilience of reverse link channel connections in a variable RF environment. Because the orthogonal link system must be aligned in time, the temple: the orthogonality of the user to the next user, so the timing control loop from the second solid-base station is use. For the two base stations in the 201206095-reverse link direction, the orthogonality is not easy to achieve because the relative propagation time delay complicates the time alignment between the two base stations. Therefore, in order to use the orthogonal reverse link with soft handover operation, there is a primary reverse link base station that provides timing control and an auxiliary base station that can receive and receive in an asynchronous manner. The condition of the feature is defined as deciding when to re-specify the timing control from the base station to the auxiliary base station to allow for the change of the orthogonal link from the base station to the second base station of the 5th base. . When there is only one orthogonal base station, the signal level received at the second base station may be sufficient for reception. These signals can be used to provide for diversification. This is especially useful in high mobility systems. Although only #- single-base stations implement timing control (4), in a preferred embodiment, both implement power control. This is because, when the path loss of the non-orthogonal base station decreases as the user moves, the received power can become so strong that it begins to generate excessive interference and reduces the capacity of the auxiliary base station. Thus, when the signal level is suitable for reception at the secondary base station, a command or message is transmitted to the subscriber unit to reduce the power of the transmission. (d) These commands affect the received power at the orthogonal base station and the non-orthogonal base station. The re-designation of the timing control system from the primary base station to the secondary base station is appropriate. A typical condition can be, for example, when the 201206095 path loss for the non-orthogonal or auxiliary base station exceeds a certain margin, for example. The existing split multi-access system defines the reverse link channelization in a non-orthogonal manner. This system is 炅 又 又 又 又 又 ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ The orthogonal and non-positive-compatibility energy can be achieved by the use of the same for the same unfolding stone horses of the same drought, and ^ ^ ^ ^ . When these users: = ΐ: are reversed to some user signals; 2 - the displacement and can be based on the code shift and the orthogonal code, the system will not be more than the existing code division. Therefore, the two non-communication signals generate more dry dogs with an orthogonal main handover operation, which can be implemented. It is necessary to base the base hall and the non-orthogonal auxiliary base station. The main base station of Shida, Hai, is re-established by an auxiliary base station and the jujube... The current order of the Taipa is the handover system ρ έ _, ', Ρ The reverse link timing control keeps the π system already occurring) and the code phase offset. Use a value: a large delay loop of U may be too r, one bit of differential transmission is controlled by the new base station: _^ and when it is known, it cannot be quickly born, a her sculpture " Hey. Therefore, when the handover operation is re-targeted at the fast-tracking location, the "goer message system can be used as a loop, where the overall timing is adjusted to , , , or opposite. In the case of the 9 201206095 5 Xuan user unit is told to implement a rough timing adjustment of the timing item and the information in the sequence message. The early detection system automatically responds to the conditions for the timing control handover operation - Depending on the conditions: According to at least the upper seven. The measured value of the alternative path exceeds a threshold for the period; 疋, the measured value in the two path exceeds the current period relative to the current road. A threshold value; or: the previously selected path is reduced to less than an absolute measurement. 4. The candidate path system exceeds an absolute measurement value, where the 'f meta-measurement value can be the following one or more : a. power; b. signal to noise ratio; c. power variation value; d. signal to noise ratio variation value or e. two paths (ie, orthogonal link and non-orthogonal chain Relative ratio of the above measured values between the roads - Orthogonal link (RL) power control (or signal-to-noise ratio control) can be based on orthogonal (aligned) and non-orthogonal paths. When a non-orthogonal path signal is mismatched The analog system meets the items listed above. = Quality condition When a power control loop is active, the timing control of the user cover 7G can be redesignated to be associated with the non-12 201206095 orthogonal path. The power control loop, if one is not -: message or report 'the command can be the minimum of the noise ratio for each :: path. The path is tracked, and - one requires power and the other The system is as good as two two; the second is the force; the force is ordered to decrease. This system is also applicable to the sexual father, in which the output of the user unit is at all power measurements. It is only necessary to increase the information. It is necessary to increase the offset value between the non-orthogonal path of a base station and the command from the orthogonal path. For example, , visit τ six __, /, have a relative After the reduction of the diameter control power, the calculation is ignored and the other knives become y, and the command system that is not more or less power may be maintained for two periods. Orthogonal region 2:: or a similar method as described above. The domain system can be used as a time series orthogonal system by a base station = orthogonal base station and non-orthogonal base station:: work; Second: When the two stations are maintained, the packet is transmitted to the subscriber unit transmitter. The S-way link is powered by the parent base station: whether the A-input is in each individual Base station 1:; j: order can be based on the achievement. The quality measurement can be two; 2 value is L error rate, signal pair 13 201206095 miscellaneous, than 'received power or interference density Ec /lo. Assuming that the f-value is satisfied, then a command to reduce the transmission power is transmitted =. Since the pick-up terminal receives commands from the two base stations, it will usually receive conflicting commands. When this occurs, the command is followed by the command to reduce power if a low power command is issued. This can be implemented using a mutually exclusive or (exclusive-OR) function; for example, only when both bases 1 command to increase power, an action to increase power is generated. If a base station command is to reduce power, then a power reduction action is generated from the access terminal. This is also the same for the command, where the smallest of the power plus I or the dare to destroy a small amount is followed. A 2: is a code division multi-channel access communication system 10:: code division multi-channel access communication system 10 system use - system in the organization, a first level of correction, broken buckle 疋A unique long code with a different code phase offset, and the second level of logical channel is used by using a 妓:: code phase offset and a combination of one for each frequency; additional encoding of the unique orthogonal code The program is set. In the following detailed description of an embodiment, the system is taught to make the shared (four) system: channel or radio frequency channel.

Once a link is established, the battery: The user system can then transfer the data to the file 5 and receive the data from the file server 2 3 个. The circulation data channel 2 5 2 - the dimension is thin, the back chain is 5 3 ° The channel access channel 2 5 1 is used by the household access order 兀 2 4 0 to transmit a message to the base station to process the crying 9 Ο η ” ” to request the circulation data channel to grant them and then the designated The circulation data channel 2 5 2 is carried by the 22 early 214 carrying data to the base station processor.

S 19 201206095 道 2 5 2. In addition, a maintenance channel 2 5 3 can carry, for example, synchronization and power control messages to further provide information transmission via the reverse link 50. Similarly, the user of the second group has a forward link 40, and the forward link 4 includes a signaling channel 24.1 'a plurality of circulation data channels 2 4 2 — 1, · · , 2 4 2 —t' and maintain channel 2 4 3. The transmitting channel 2 4 1 is used by the ground station processor 220 to not only notify the user to access the single unit 2 1 4 forward link circulation data channel 2 5 2 system has been allocated, "Xuan user" The access unit 2 1 4 also notifies the user that the access unit 2 1 4 has the assigned circulation data channel 2 5 2 in the reverse link direction. Then, the circulation data channel 2^2 1, . . . , 2 2 2 ~ t on the forward link 4 is used to process the data from the base to the user 2 to carry the information to the user. In addition, the maintenance channel 2 4 3 is connected to the forward link 4, and the base station processor 220 carries the synchronization and power control to the user access unit 2 . It should be understood that the typical system/ is more than the communication channel 2 4 1 or the maintenance channel 2 4 3 is more than the circulation channel 2 4 1 . In the preferred embodiment, the logical forward channel channels 24, 242, 2 4 3, 25 1, 5 2 and 2 5 3 are assigned a pseudo-random noise class by each pseudo-random channel. Dao Shi - 么', k Ma Therefore, the 糸 system is a so-called sub-: 夕路取取 system, in which 'multiple coded channels can use the same RF channel. The logical or code channel can also be entered in a user's access unit 2 i 4 of a plurality of activities. The sequence of the scale signal processing operations is typically implemented 'to encode the logical channels 51, 52 and 53 of the respective reverse link 50. In the direction of the reverse link, the transmitter is the user access unit 2 1 4, and the receiver processes the crying 2 2 为 for the base station. The preferred embodiment of the present invention is for a digital operation such as a multi-channel operation of a system operating according to the is_95b standard. The existing user of the system also appears on the reverse link 5 Implemented in the environment. In a system of the IS_95B standard, the reverse key == sigma access frequency signal is identified by specifying a non-orthogonal pseudo-random noise code. Referring now to Figure 2, the channel sequence for use in the first group will be described in more detail. The first = group of users includes, for example, digitally coded multiple access mobile power; the user of the system' encodes the signal according to the criteria described above. Thus, the individual channel is identified by modulating the input = speech signal with a pseudo-random noise code sequence of: mother-channel. To be clear, the channel encoding program takes an input digital signal that represents the circumstance: acupoint Q and 込 贝 ^ 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 一个 ^ ^ ^ ^ ^ ^ Path to - the multiplier 3 〇 6 - q (four) ugly for the random noise generator 3 Ο 5 series to provide a short use for the purpose of the spread spectrum (in this case, - 2 15

S 21 201206095 — 1 or 3 2 7 6 7 bits. The length of the sparse code is typically used with the first group " code. 'This' is the same channel as the short channel. A logic of 10 0 is multiplied by a variable step by the (q) signal by the two signal paths, the last extra long pseudo-random code. This is caused by long code crying to: (1) and 3 0 8 — and 308 — and long code multipliers. The long code is used to uniquely:::: every - (four) long-length horse on the reverse link 50, for example, only every 2 4 2 -f :; The short-cut wafer capture rate is applied, for example; the bit system is applied to the short-code modulation program to convert the mother-single bit, so that the progressive spread spectrum system does not occur. Two other: the user is identified by applying the pseudo random random phase offset to each user. It should be understood that the use of the first group of two == other synchronization steps. Specifically, and therefore need not be designed to be asynchronous. Figure 3 is a more detailed diagram of a frequency programming program for the user 2 work of the second group. The second group of 2 cases is a wireless data user that includes a binary signal according to a data transmission optimization format. The individual channels are identifiable by a pseudo-random noise to modify the input signal to identify that the pseudo-random noise code is the same code sequence as the user 1 1 用于 for the 201206095 first group. . However, as can be appreciated below, the channels in the second group 21 are uniquely identified by a particular orthogonal code such as a Walsh code. Day: It is true that the channel coding procedure for the user of the second group uses an input digital signal 4 〇 2, and is applied by one to generate 11405, the Walsh code generator 413 and The long code produces many of the codes generated by the 4 0 7 . As a first step, a quadrature modulator 4 〇4 provides an in-phase (!) and quadrature (q) signal path to a first pair:: state 4 0 6 -1 and 4 〇6-q . The short pseudo-random noise code generator 4 0 5 series provides a short code. In this example, is a short pseudo-random display of each of the channels in use? Purpose 2 1 5 length code. Therefore, the short code system is the same as that used for the first group 1 1 A · code. A second step in the procedure is to apply an orthogonal gamma such as that produced by the sigma generator 4 13 . This is done by multipliers 412-i and 412-q applying orthogonal codes to each of the in-phase and positive-parent signal paths. The orthogonal code assigned to each logical frequency is different and uniquely identifies such a channel. Among the four final steps of the program, a second pseudo-slave code is applied to the (1) & (q) signal path. Therefore, the =2 code generator 4 Q 7 transfers the long code to an individual synchronizing multiplication: 1 0 8 —i and the orthogonal multiplier 4 〇 8 —q. The long code system does not recognize each of the second group 2 10 . Ming 201206095 It is true that the code system can be used for the same group of users in the first group that use it to identify the group. For example, it is known in the same way as a short code wafer rate code such that a bit of the long code is applied to each bit rotated by the code side program. In this way, the user in the second group 210 presents the first-to-one user of the first group. However, in the case where the user of the second:: 21〇 has been assigned a unique orthogonal Walsh code, the user of the second group 2 1 can be recognized by one. When the preferred embodiment is implemented on a reverse link 5, additional information must be provided to maintain orthogonality between different users of the second group 210. It is expressly stated that a dimension & channel 2 4 3 system is thus included in the forward link 4 〇. The dimension, or "heartbeat" channel, provides synchronization information and/or other timing signals such that the remote units 2i 4 can properly synchronize their transmissions. This maintenance channel can be divided by time slots. For more details on the formatting of the forward link maintenance channel 2 4 3, the application can be referred to in the application for the maintenance link of the active/alternate request channel in February 2nd.

Similarly, the position for the antennas can thus be the same. This allows the user of the second group to be set up and by the existing user. 1 1 〇 The equipment used and the location where the body is built. This greatly simplifies the configuration of the wireless infrastructure used by the users of the new group, for example, the new location and the new antenna location. Department.

When the long codes are in phase, the unique and identified codes of the reverse link signals are orthogonal to each other. The long code in the road signal is in phase with the long code of the other reverse link signals of the other access terminals 2 i 3 in the same mutually orthogonal reverse link group (ie, temporally aligned) Then, the base station processor program 7 ends in step 730. If the long code in the reverse link signal is in the same mutual offset group as the other If the terminal 2 has different length codes of the reverse link signal, the base station processor program 700 is maintained to step 7 2 〇', wherein the overall timing offset is determined by the orthogonal timing control. The device 5 is implemented as described above with reference to Figure 5. »Xuan base $ handler program 7 〇〇 proceeds to step 7 2 5 'In this step' the base station processor 2 2 A command or message form transmits the overall timing offset to the access termination 2 1 3.

The power level offset is transmitted to the access terminal 2 1 3 in the forward link. If the power level adjustment is not performed in the south, the reference is made. The first base station: the traitor program 8 〇〇 and the second base station processor program 8 〇 2: the individual program system proceeds to step 8 work 8, where one off = yes, the timing control soft handover operation should The decision to be initialized is only ^. The sequence control system can be initialized according to a set of the following conditions: ' (a) the measured value of the alternative path More than one threshold for a pre-specified period; (b) a measurement of an alternate path for a specified period exceeding a threshold relative to the current path; 36 201206095 (C) currently selected The path system drops below an absolute value and (d) the candidate path system exceeds an absolute measurement, wherein the diagnostic measurement can be one or more of the following: (a) power; (b) signal pair Noise ratio; (0 power variation value; (d) the variance value of the noise ratio; or (e) the relative ratio power of the two paths. If the initialization of the timing control handover operation has been initiated, the base station processor 220 updates the base station processor and the base station controller 丄23. The access terminal j 2 1 3 can also be informed of the timing control handover operation. If the timing control system has not been softly handed over, then the programs 8 8 and 8 〇 2 are carried out to step 8 2 4, in step 8 2 4, 10,000 - another base station processor 2 2 〇, base After the controller is connected, the terminal 213 will control the timing of the reverse link signal = the command or message is transmitted to the base station processor 22 and the decision to accept the timing control is implemented. If the base 糸 is released or accepts responsibility for timing control, then the 0 and 802 lines proceed to step 830 to determine the operating parameters of Li Tong; otherwise, the programs δ 〇〇 and 8 〇 2 = step 8 〇 3 Receiving I from the access terminal 2 to the I message. The program executed by the terminal 2 1 3 is connected to the terminal 38 3, and the program is received in step 839; First, if the feedback is not received, the feedback is as follows: The feedback is as follows: In the embodiment, if the feedback is received, then 庠: 3: 3 9 Temple to be fed back. False θ, j ° Hai proceed to step 8 4 2 to determine if a rough timing adjustment command or message has been received. The coarse timing adjustment is implemented in step 845 if a coarse timing adjustment command or message has been received. The library understands that 'this coarse timing adjustment can be an absolute or relative measurement, as described above. In step 848, the access terminal 2 1 3 determines whether a subtle timing adjustment command or message has been received. If a subtle timing adjustment command or message has been received, fine timing adjustments are implemented in (4) 8 5 1 . It should be understood that the fine timing adjustment is typically a differential command or message. In the fine timing adjustment S, the program determines whether a power level adjustment command or a message system has been received. If a power level adjustment command or message has been received, then in the step 855, the access terminal 2 1 3 adjusts the power level. After adjusting for timing or power, the operating parameters of the access terminal 2 1 3 are updated in step 8 6 0. After updating the system parameters, the program 803 repeats in step 829 to wait for feedback from one or more base station processors 2 2 . 8 38 201206095 Figures 9a and 9B are flowcharts of procedures 9 〇〇 and 902 executed by the base station processor 2 2 2 and the access terminal 2 1 3, respectively, for adjustment by the access terminal 2 1 3 The power level of the reverse link signal transmitted. Referring to the program 9 Q Q executed by the base station processor 2 2, the program 9 ◦ 0 starts at step 9. In step 11, the base station processor 220 determines whether the access terminal 2 1 3 changes the power level of the reverse link signal in the step 9 work. If the road signal is in the right position, then only the person and the user are sent to the access terminal 2 1 3 in the form of a command or message. The base station processor 2 ends in step 915 in the program 900. To22〇# From the access terminal 213, the step feedback is in step 93, and the second step is to step 骡qu. Then the program 9 2 0 is subscribed to the main 4 9 3 5 in step 9 3 5 The base station processor 2 2 requests one: No all base systems are implemented. If all the base stations _ 卞 determine the power level to increase, _ program 92 (; H 〇 2 seeking a 0: in the humiliation 9 4 〇, the receiving terminal 2H two steps 9 4 minimum increase feedback - Xi 13 series Add one bit. If not all bases; I: increase the power level of the link signal, then in step 9 4 5 and ask for a power ground processor 2 2 Whether any basis is implemented. If at least the force 〒 + bit is reduced - the power level is reduced, when listed in Q = 2 2 〇 is requesting the illusion in step 950, the access terminal 2 39 1 201206095 1 3 reduces the power level as much as a minimum reduction feedback. The program 9 2 0 ends at step 9.5, or can = loop back only to step 9 3 0, waiting to receive a power level Bit feedback. Although the power control of the orthogonal and non-orthogonal base stations is maintained, commands or measured values can be transmitted to the subscriber base transmitter via a forward link (ie, the access terminal 2 3) The power control command from each base station processor 22 can Depending on whether a signal quality measurement is achieved at an individual base station processor 220. The signal quality measurement can be a bit error rate, signal-to-noise ratio than 'received power or Interference density Ec/丨〇. Assuming that the measured value is satisfied, a command to reduce the transmission power is transmitted. Because the receiving terminal 2 1 3 receives the crying 2 2 0 from the two base stations. The command, usually the system will receive the conflicting command. ^ When this happens, if a command to reduce power is generated, then the terminal 2 1 3 follows the command to reduce the power. This system can use a mutual exclusion or ( Exclusive_0R) is implemented as a function, for example, only when two base station processors 2 2 command to increase power, an action to increase power is generated. If there is a base station processor 2 2 0 system The command reduces power, and a power reduction action is generated. This is the same for a plurality of bits, where the minimum increase in power or the maximum amount is 201206095 Although the present invention has been shown in the drawings; 较佳 the preferred embodiment of the invention, '", '' ", the person who knows the skill of the art should understand that When you are a straight girl, you can't keep up.
