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.

Most of the residents who have migrated to Wu Guo, Europe and other industrialized areas of the world have more than one product to choose from. -, a number of services for the electronics and computer industry, the number of smashing, helmets, _; 5,,, growth, the contribution to the increased demand for access to the Internet and spears . In the use of the package handheld personal digital assistant, the Internet-enabled action, the development of the device, especially the portable type, the system has caused a corresponding increase in the demand for wireless access.曰 Although the mobile phone and personal communication service networks are widely deployed, some systems are not intended to be used to carry streaming information. Rather, the burst mode digital communication protocol required for communication over the Internet is designed to efficiently support continuous similar signals. Also considered; the sound system is suitable for _ a communication channel bandwidth of about 3 kilohertz. However, for an effective Internet communication such as Internet Pan, a data rate of at least 56,000 bits per second is acceptable. 7 200824320 In addition, the nature of the circulation data stream itself is different from the nature of voice communication. The voice system requires a continuous multiplex link; that is, the user at one end of a connection is expected to be continuously transmitted to and received by the user at the other end of the link. However, accessing web pages via the Internet is generally very culinary. Typically, a remote client computer user specifies the address of a computer file such as on a network server. The request is then formatted into a fairly short message message, typically less than i 〇 〇 长度 bytes. Then, the other end of the link, such as at one of the network servers in the network, is requested with text, video, audio, or video material that can range from 1 kilobyte to millions of bytes. The information was shot in response. Due to the inherent nature of the latency of the Internet itself, users typically expect to delay at least a few seconds or more before the requested content begins to be delivered to the user. Then, once the content is delivered, the user can spend or wait a few seconds or even minutes to view or read the content of the page before the next page is downloaded. Furthermore, the voice network is built to support the use of high mobility, that is, 'the use of extremely long lengths to support the speed of the highway in the form of mobility' = mobile and personal communication services based on the word ^ Users of the network maintain links as they move along a highway at high speeds. However, the typical user of a laptop is quite static #, such as sitting in front of a table. Therefore, 'the action unit for wireless voice is the action unit: the important point of high-speed mobility is typically not needed to support data access. [2008] The improvement of some components of the existing wireless infrastructure is more Efficiently suited to wireless data is meaningful. The additional functionality of implementing new user levels for users with high data rates and low mobility should be backwards compatible with the functions currently used for users with low data rates and high mobility. This will allow the use of the same frequency allocation plan, base station antenna, construction site, and other aspects of the existing voice network infrastructure to provide new high-speed data services. It is particularly important to support the highest possible data rate on the reverse keyway of the network carrying data on the reverse keyway, for example from the remote unit to the base station. Consider existing digital operations such as Ιδ·95 code division multiple access ((10) Divisi〇n M_ple Aceess, CDMA) to specify the use of different horse sequences in the forward link direction to maintain the minimum interference between channels . It is clear that Lu Zhi, such as a system using orthogonal codes on the forward key, defines individual logical channels. However, the best practice of such a system requires that all such Mae time be aligned to a particular boundary so that it can receive three m-intersections. Therefore, the transmission system must be synchronized. = non-one in the forward link - a special consideration, because all from: in the same position, that is, in a base station transceiver enterprise, the current digital action is divided into the standard system is not - ^ The orthogonality between the channels in the reverse link direction is required. In general, the word 'synthesis synchronization originates from a plurality of delays located at different locations, 7G early and may be ^ ^ ^ ^ ^ ^ from the base station. Rather, these systems typically use a pseudo-random scalar garbled garbled with a transmission-difficulty-to-displacement to identify the individual reverse link 200824320 channel. However, the use of this garbled code excludes the possibility of transmission by different users that are orthogonal to one another. Accordingly, one embodiment of the present invention includes communication between components of a first group of users and a second group of users. A user of the first group of existing users who can receive a digital coded multiplexed mobile telephone system is encoded with a common first code code for a unique code phase offset transmitted to each user. It can be uniquely identified. The user of the second group of a high speed data service encodes the transmission using the same code and one of the code phase offsets of the code. However, each of the users of the 'second group' encodes its transmission with an additional code that is unique to each of the users of the group: group. This allows the transmissions of the users of the second group to be orthogonal to each other while still maintaining the overall appearance as a single user of the first group. The code assigned to the users of the first group can be a common The chip rate or pseudo-random code. The code assigned to the user of the second group ^ can be a group-only orthogonal code group. The I component of the terminal can be a scrambled one with a longer pseudo selected. The code of the unique phase offset of the noise sequence is recognized. In a preferred embodiment, certain steps are taken to ensure that the correct operation of the communication between the two groups of users is also known as "the heart of the two." The system can be dedicated to '--the same y-channel. This system allows for the case where the encoding mechanism is maintained in the case of two 200824320 reverse link-side killing volumes The correct timing of the transmission of the terminals of the second group. In another embodiment, the users of the second group can be assigned to the last time slot of the last name, and thus 'by using time-sharing multiple accesses斟Again, the point is the user of the second group as a whole; the transmission of the user of the group is a single user. The principle of this month is allowed to be designed for vehicles. The code division multiple access system of Mobility 7 supports soft offline operation of both orthogonal channels on its reverse link 'to increase the reverse link channel link in a high variable RF environment Resilience. Because an orthogonal link must be aligned in time, Maintaining the orthogonality of the user to the next user, so the timing control loop from a single base = (4). For the reverse key ς pair; In other words, the orthogonality is not easy to achieve, because the phase-to-mid, broadcast-inter-delay makes the time alignment between the two base stations complicated. = This is to use the orthogonal reverse link with soft offline operation. A primary reverse link base station that provides timing control and an auxiliary base station that can receive transmissions in an asynchronous manner. The condition is defined to determine when to reassign from the primary base station to the The timing control of the auxiliary base station to allow for the change of the orthogonal link of the first base station = ^ two base stations is advantageous. When there is only one positive base and the base is wide, the signal received by the second base station is accurate. The bits can be sufficient to receive. These signals can be used to provide for diversification. This is especially useful in high mobility systems. ', 11 200824320 Although;,;, /, has a single base station implementation timing control In a better In the case of Bessie, both implement power control. This is because when the path loss of the non-orthogonal base cell decreases as the user moves, the received force rate can become so strong that it begins to generate. Excessive interference, minus 2 "capacity of the auxiliary base. Therefore, when the signal level is suitable for receiving at the auxiliary base station, the command or message is transmitted to the user. Although these commands affect the received power at the non-orthogonal base station, it is appropriate to re-specify the timing control from the base station to the auxiliary base station. The case of a business type can be 斟 兮 兮 ^ 为 对于 对于 对于 对于 对于 对于 对于 对于 对于 对于 对于 对于 对于 对于 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量 测量The ΐΐ 接 ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί Achieved by the primary and/or non-father reverse compatibility users. When this is used = common: the orthogonality of the same unfolding monument is the material; the second = signal is not possible for time alignment, but instead is shifted to the orthogonal code and is only geo-discriminate = unique displacement and can be coded according to the code The existing == number of the multi-channel access system does not compare to the existing interference. Therefore, as with today's ~4 non-father signal generating more dry-orthogonal primary base stations and soft offline operations, it can be implemented when the primary base station is heavy: the secondary base station. When an auxiliary base station comes in 4疋, the current timing system is reversed, and the reverse link timing control is offline. 12200824320 has already occurred, which may have a large delay and code phase offset. Using a conventional one-bit differential timing control loop may be too slow to quickly obtain the positive parent with the new base station when it is operating offline. Thus, when this offline operation occurs, an overall timing adjustment command or message can be used to quickly realign the reverse link, where the overall timing adjustment can be absolute or relative. In the case of the timing, the User# element is informed to implement a coarse timing adjustment, and in the case of the timing message, the subscriber unit automatically responds to the information in the timing message. The conditions for the offline operation of the timing control may be determined according to the conditions: one of the lt; one of the measured values of the alternative path is more than one of the thresholds; B' the 'month 2' - an alternative path The tears | the measured value exceeds a threshold relative to the specified period of the day; the target path is in the current selection of the road; or: the lower ^ is lower than - an absolute measurement Value 4. The candidate path system exceeds an absolute measurement value, wherein the measured value can be the following: or a. power; human eve 1 solid · b. signal to noise ratio; c · power variation value d. The relative value of the above measured values between the signals of the signal-to-noise ratio and the value of the two paths (ie, the 'positive' is not the parent's link). The power control (or signal-to-noise ratio control) of a quadrature material (RL) can be based on orthogonal (aligned) and non-orthogonal paths. When the signal-to-noise ratio of a non-orthogonal path meets the quality conditions listed above and the power control back (4) is active, the timing control of the subscriber unit can be newly assigned to the non-orthogonal path.

For example, before the orthogonal path is reduced by (4), it needs to be reduced by the non-positive control power; the more or less may need to be the command of the more-(four) turn-force rate. The Sixth Fihh (four) - the longer period of the paragraph. The correct domain in the base station can be treated as a trampoline 1: 犬 The dog is treated like a negative method. Tianye Preface is composed of a base station and is orthogonal to the United States A; 5 system 4, the power control system is OKI Zhenghao base: M: and non-orthogonal base stations. The orthogonal and non-orthogonal bases When both stations are maintained, the package system or the message system must be along the forward route link::! The value of the command Hande H this user unit pass 14 200824320 transmitter. ^ The power control commands from each base station can be based on whether a quality measurement is achieved at each individual base station. The value of the mouth can be the bit error rate, the signal to noise ratio, the received T rate or the interference density Ec/l0. Assuming that the measured value is satisfied, a command to reduce the transmission power is transmitted. Because the access terminal receives commands from the two base stations, it usually receives the conflicting commands. v condition produces %, if a power reduction command is generated, the access terminal follows the power reduction command. This can be implemented using a mutex or (exchiSlve-0R) function; for example, an action to increase power is generated only if both bases are commanding to increase power. If there is a base station command to reduce power, then a power reduction action is generated from the access terminal. This is also the same for the number of bits 7 , where the smallest increase in power or the maximum amount of extinction is followed. [Embodiment] FIG. 1 is a block diagram of a code division multiple access communication system 1 . The code division multiple access communication system uses a signal coding mechanism, in which a A level of logical channel is assigned a unique long code with a different code phase offset, and a second level of logic frequency is used by each using a common code and a common code phase offset and a combination An additional encoding program for the unique orthogonal code of the channel is set. In the following detailed description of a specific embodiment, the communication system 1 2008 15 200824320 is described such that the shared channel resource consumption is - a wireless channel or a radio frequency channel. However, it should be understood that the techniques described herein can be applied to implement shared access to other forms of media, such as telephone connections, computer network connections, cable connections, and access to a demand-driven basis. Other physical media that are allowed under. #系统系统10 provides - the first group of users U 〇 and a first group of users 21Q wireless communication. The first group of users 110 is typically an existing user of a mobile telephone device, such as a wireless handset 1 1 3 - 1, 1 1 3 - 2 and/or placed in a vehicle In the mobile phone 1 1 3 _k. The first group of users 110 is primarily used in a voice mode network whereby its communication system is encoded as continuous communication. In a preferred embodiment, the transmissions of the users are forwarded by the subscriber unit 丄丄3 through the forward link 4 and the reverse link 5 〇 RF channels. The signals are managed at a central location comprising a base station antenna 181, a Base Transceiver Station (BTS) 120' base station controller (BaSe Stati(10) controller, BSC) 1 twenty three. Therefore, the user 1 1 of the first group is typically incorporated into the voice talks using the mobile subscriber unit 、3, the base transceiver station i 2 〇 and the base station controller 1 2 3 Connect to the phone via the public switched telephone network 1 2 4 . The forward link 4 used by the users of the first group can be coded according to well-known digital action standards, such as Telecommunication Industry 16 200824320.

The e-monthly devices 2 1 2 are typically laptop computers 2 丄 2 - 1, hand-held units 2 ^ b ‘Internet-enabled mobile phones or a number of assistant-type computing devices. Each of the computer devices 2丄2 is connected to an individual user access unit 2丄4 via a suitable line connection such as a link in the form of an Ethernet. A user access unit 214 is connected to the computer device 2 1 2 coupled thereto through the base station processor 2 2 , the internet gateway 2 18 200824320 2 2 and the internet 2 p 4 μ The network file server is crying 0. In the reverse link direction -23 1 2 toward the feeding device 2 3 一 电 电 电 耻 置 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 Until the user picks up the user, the 214 is framed and coded by the appropriate wireless link and the frame is framed (that is, the frame is wired). Then, the appropriate antenna? Fi Wan 9 1 〇D work..., the line data packet is transmitted through the 2, 8 and one of the RF channels containing the reverse link 50. At the central base, the phase of the test is to be tested. At the base location, the base station processor 2-0 picks up the radio link and frames it and reformats the packet in the form of an internet protocol' and forwards it through the internet channel 2 2 2 The packet. Then the packet is routed to its final destination by any number and/or any form of network such as the Internet 2 2 4 Transmission Control Protocol/Internet Protocol, so that 1^ a 0 0 routing, such as the network file server ^ 〇〇 ° data can also be in a forward chain The direction of the path 4 is transmitted by the network slot server 203 to the computer devices 2 丄 2. In this example, an internet protocol packet originating from the file server 2 3 〇 The network gateway 2 2 2 is moved through the Internet gateway 2 2 4 to reach the base station processor 2 2 0. Then, the appropriate radio protocol frame and coding system is added to the Internet. The packet is transmitted. Then, the packet is moved through the antenna 2 16 and 2 1 8 to the intended recipient = the access unit 2 1 4 the received user access unit 2 丄 4 decodes the benefit line The packet is formatted and the packet is forwarded to the intended computer device 2i2 that implements the Internet Protocol layer 19 200824320. Therefore, 'a given thunderstorm 孽 Ί 〇 电 2 2 2 2 2 2 The file server 203 is considered to be a user system at the end of the duplex connection of the network network at the j咏, and the construction of the road coordination layer.

From the point of view of the user of the second group, 'the reverse link 50 is a radio channel containing exactly many different forms of logic and/or entity' including an access channel 2 5彳Α ^ Z b 1, a plurality of circulation data channels 2 5 2 — t, and _ maintenance channels 5 3 2 5 2 -1, · · · The reverse link access channel 2 51 is the user access unit 2 4 〇 used to send a message to the base station processor 2 2 Q to request that the flow channel to grant them. Then, the designated circulation data channel 2 52 is carried by the user access unit 214 to the base station processor 220. It should be appreciated that a given Internet Protocol layer link can actually have more than one tradable data channel assigned to it 2 2 2 . In addition, a maintenance channel 2 5 3 can carry information such as synchronization and power control to provide a real circulation data channel through the reverse link 5 Q. 2 Similarly, the second group The user of the group has a forward link 4 〇 'The forward link 4 包含 contains one communication channel 2 4 workers, plural, 2 4 2 — t, and maintenance, storage / 1 〇 / eight , flat hard Siam 2 4 3. The transmitting channel 2 4 system is used by the base station processor 2 2 to not only notify the user access unit 21 4 to the two-way stream 20 200824320 data channel 2 4 2 - 1 data channel 2 5 2 system has been The user access unit 2 l 4 is also assigned, and the user access unit 214 is also notified of the assigned circulation data channel 2 5 2 in the reverse link direction. Then, the circulation 2 4 2 - t on the forward link 4 is used to carry the information information by the base station processor 220 to the user to receive the military 2 1 4 . In addition, the maintenance channel 2 4 3 carries the synchronization and power control information to the user access unit 2 1 4 on the forward link 4 谤. It should be understood that there are typically more than one circulation data channel than the transmission channel 2 4 1 or maintenance, channel 2 4 3 . In the preferred embodiment, the logical forward link channels 2 4 i , 2 2 ' 2 4 3 ' 2 5 丄, 2 5 2 and 2 5 3 are designated by pseudo-random channel: a pseudo-random Noise channel code. Therefore, a so-called sub-matrix access system, system, in which a plurality of coded ^ : = = : the same RF channel. This logical or code channel can also be determined. In the early stage, the Z 1 4 is divided or the signal processing is selected as the sequel. The sequence of the 乍 is typically implemented, and the reverse link 5 〇 button is used to encode the individual channel 5 i, In the direction of 5 2 and 5, the error is crying / d is in the reverse chain, the zero V state is the user access unit 2, and the receiver is the base station processor 2 2 〇 - 2 For example, an existing user of a digital system such as a digitized action Christine's, 糸, and a first coded multidirectional link 50 on the basis of the preferred implementation of the method 5 is also present in the Anti-reverse link code division: Know. In the S'95B standard system, the channel access signal is identified by specifying the non-orthogonal pseudo-code with the 200824320 machine noise code. See Ming Ming > 2, the channel coding program for the user 1 1 0 of the first group is described in more detail. The first group user 匕 3 exemplifies the δ digital code division multiplexed mobile phone system. The user encodes the signal according to the IS_95B standard described above. Therefore, the channel is used by - for each channel. The sequence of the noise code and (4) the digitized voice signal of the input and the input are recognized. Specifically, the channel programming program takes the digital signal 3 η 9 — plus 0 2 — representing the transmitted information. The quadrature modulator 3 0 4 provides an identical and orthogonal (q) signal path to the pair of multipliers 3 0 6-1 and 3 ::1. A short pseudo-random code generator 3 0 5 Series provides - short for the purpose of the spread spectrum (in this case, a 2 "one or = 6_=) long ... ^ ', '1 〇 each of the same logical channel code. One ice brother-code modulation step is achieved by multiplying the two signal paths by -°. 3 〇 7 and long code multipliers 3 0 8 — i and 3 〇 5^^. W-only recognizes the reverse keyway. For example, the parent is a user. The Changma can be a very long code, / for example, only once every 2 4 2 _ code wafer rate gentleman. The long code is applied to the short output w/r ^ ', for example, a bit of the long code is applied to each output by the short code modulation program. 70 further spread the frequency system Individual users are identified by applying a different phase of the pseudo random random code to the 22 200824320 phase offset to each user. 2 Knowing 疋' For the user 1 10 of the first group, it is not necessary to catch: other synchronization steps. Specifically, the transmissions on the reverse link 50 are designed to be non-synchronous and therefore completely orthogonal. And Figure 3 is a more detailed diagram of the channel coding procedure for the user of the group: 2 1 .

However, as can be appreciated below, the channels in the second group 2 1 are only derived from a particular orthogonal pin such as a Walsh code. Specifically, the channel coding procedure for the user of the second group is to use a round-robin digital signal 4 0 2, and apply a short code generator 4 0 5, a Walsh code. A plurality of codes generated by the generator 4 1 3 and the long code generator 4 〇7. As a first step, a quadrature modulator 4 〇 4 provides an in-phase (1) and quadrature (q) signal path to a first-to-first multipliers 4 0 6 -i and 4 ◦ 6 -q. The short pseudo-random random code generator 4 〇 5 provides a short burst. In this example, it is a 2 1 5 length code for the purpose of the spread spectrum. Therefore, the short code is the same as the short pseudo random code used for each of the channels in the first group of work. The second step in the procedure is to apply an orthogonal code such as that produced by the Walsh 23 200824320 code generator 4 1 3 . This family is completed by multiplication crying $12 i and 4 1 2 — q applying orthogonal codes to each in-phase and six-one parent 5 tiger paths. The orthogonal code assigned to each logical channel is different and uniquely identifies such a channel. Among the final steps of the procedures, a second pseudo-random noise long code is applied to the (i) and (q) signal paths. Therefore, the long code is generated by the system to transfer the long code to the individual in-phase multipliers 4 〇 8~i and the positive parent multiplication 4 〇 8 — q. The long code uniquely identifies each of the users of the second group 2 1 0 . Specifically, the code system can be one of the same long codes used in the first group of users α χ 唯一 that uniquely identify the first group. Thus, for example, t, is applied in the same manner as a short code wafer rate code such that one bit of the long code is applied to each bit output by the short code modulation program. In this way, all the users in the second group 2 1 Q present the -single of the first group 1 1 0 - the existing user 'however, in the use of the second group 210 In the case where a unique orthogonal Walsh code has been assigned, the user of the second group 2 1 can be uniquely identified. 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 2i. It is clear that a maintenance channel 2 4 3 is therefore included in the forward link 40. The maintenance or "heartbeat" channel provides synchronization information and/or other timing signals such that the remote units 2 1 4 can properly synchronize their transmissions. This maintenance channel can be divided by time slots. For more details on the format of the 200824320 format of the forward link maintenance channel 2 4 3, you can refer to the application in the application on February 1st, the name of "Use Activity. / Alternate Request Channel" U.S. Patent Application Serial No. 09/775,305, the entire disclosure of which is incorporated herein by reference. It will be appreciated that certain infrastructures may thus be shared by the user 2 1 of the second group and the user 丄 1Q of the first group. For example, although the antennas 2 i8 are shown as being separated, the earth in the figure can also be a shared antenna on the antenna. Similarly, the locations for the antennas can thus be ancestral. This allows the user 21 of the second group to share the location that has been established and established by the device and entity used by the existing user 11 . This greatly simplifies the configuration of the wireless infrastructure for the user 21Q of the second group, for example, the new location and the new antenna location need not be established. The brother 4 is a network diagram similar to the first one. In the wireless network, a first base station processor 220-1 and a second base processor 2 2 0-2 (collectively referred to as 2 2 0) provide access to the royal network (such as the Internet) Or a public switched telephone network) for accessing the terminal 213 - 2 " one 2, .. , and the handheld unit 1 Ί q ύ d base table.. a 1'113-2 and 113-3 .

Figure 7 is a flow chart of a soft offline method of transcoding multiple access reverse orthogonal links in accordance with the present invention. In this example, 'Xiao first base station ^ is executed - the mth 〇 〇, and the end of the acquisition = 213 is executed - a second program 735. After the start of step 7 〇5 in the base station processor program=700, the base station processor program 7 0 Q wants to receive one of the access terminals m 32 200824320 in step 7 1Q. Reverse link signal. In step 7404 after the start of the access terminal program 735, the access terminal 2丄3 transmits a connection terminal with other access terminals 2 丄3 on a reverse link channel in step 754. The reverse link signal having the same orthogonal code with the same reverse link signal. The base hall processor program 7 receives the reverse link signal in step 71 and continues to step 7 i 5. In step 715, the base-to-processing private system 7 determines whether to identify the long code system of the access terminal 2丄3 belonging to one orthogonal reverse link group in the reverse link signal. It is in phase with the long code of the other access terminals 2 i 3 of the same terminal strip, as shown in Figures 2 and 3. The long codes, rather than the unique, specific and orthogonal code codes such as Walsh codes, are aligned with the base station processor program 7 〇 %. When the long codes are in phase, the unique and used codes of the reverse link signals are orthogonal to each other. If the long code in the reverse link signal is the long code of the other reverse link = number of the other access terminals 213 in the same mutually orthogonal reverse link group (ie, 'time If the alignment is on, the base station processing benefit program 7 GQ system ends in step 7 3 Q. If the long code in the reverse link signal is different from the other long-link base stations of the other reverse link signals in the same mutually orthogonal reverse link group. Processing the crying chain 7 n , 私 private sequence 7 持续 continues to step 7 2 0, wherein the overall timing is biased by Jiang, the soil is determined by the orthogonal timing controller 5 1 ' See the description in Figure 5. The base station processor program 7 proceeds to step 25, in which the base station processor 2 2 transmits the overall timing offset to the access in the form of a command or message 33 200824320 In the terminal 2 7 5 , the receiving terminal program 7 3 5 ° receives the whole in the step, and adjusts the timing of the reverse link signal. The pick-up terminal program ends in step 735, and the base station processor program 35 is bundled in step 703. The 8A and 8B diagrams are flowcharts when the first base station processor 2 2 and the second base station processor 2 2 0-2 interact with the access terminal 2丄3 = 1. The first base station processor 2 2 is a program 8 00 that controls the timing of the reverse link of the access terminal 2 i 3 . The second base station processor 22 is executed by a program that does not control the processing of the timing of the reverse link of the terminal 2 1 3 . The access terminal 2 1 3 executes its own program 8 3 3 . The program 8 3 3 is capable of receiving the inverse town's adjustment for the reverse link signal in a coarse amount and a small amount, and based on the power level feedback received by the base station processor 220. Adjust the power level. The receiving terminal 2 1 3 transmits the signal received by the first base station processor 2 2 0-1 and the second base station processor 2 2 (2). In this example, it is assumed that the first base station processor 2 2 0-1 has been previously selected by the access terminal 2丄3 to control the timing of the reverse link signal. Therefore, the first base station processor 2 2 0_1 receives the reverse link positive parent signal from the access terminal 2 1 3 (step 803), and the reverse link orthogonal signal systems Other reverse link signals that share the same reverse link channel are aligned with other reverse 34 200824320 link signals from other access terminal terminals 21 that use the same reverse link channel. In step 8 〇 6 _, the first base station processor 2 2 〇 - 1 determines whether the signal sequence originated by the terminal 2 i 3 is a Q-order condition or standard. If the signal does not comply with the timing condition, or the program 8 Q(4) decides to feed back to the access terminal 2 1 3 to make the signal and the overall timing of the alignment with other signals using the same code. In step 8 3 9 'feedback is received by the receiving terminal 2 1 3. If the signal conforms to the timing condition or standard, then the program 8 proceeds to step 8 0 9 'where the program 8 0 It is necessary to determine whether or not one of them is in the order of Tian Wei. If necessary, the program 8 is transmitted to the access terminal 2 i 3 which is a fine timing offset and which one is in the procedure 8 3 3 in the step 8 3 9 by the receiving terminal 2丄3 received. If no fine timing offset is required, then the program 8 进行 进行 proceeds to step 8 1 5 . In step 815, the first base station processor 2 2 determines whether the power level of the signal transmitted by the access terminal 2 i 3 should be adjusted. Similarly, in step 5, the second base station: the device 2 2 0-2 also determines whether it should cause a power level adjustment of the access terminal 21 3 . In either case, the power level offset is transmitted to the access terminal 2丄3 in the forward link. If the power level adjustment is not required, the first base station processor program 800 and the second base station processor program 8〇2 are referred to, and the individual program proceeds to step 8 1 8, wherein the item is related to Whether the timing (4) soft offline operation should be initiated is determined.

If the timing control is soft offline, then the programs 8 〇 8 and 8 〇 2 are proceeded to step 24, step 824, 'every other base station processor, base station controller! 2 3 or the receiving terminal 2丄3 will control the timing of the reverse link signal to transmit a command or message to the base station processor 220, and the decision to release or accept the timing_ is implemented. If the base station processor is responsible for releasing or accepting timing control, then the programs 800 and 802 proceed to step 83 to update the system's operating parameters ''otherwise, the programs δ 〇〇 and 8 〇 2 The process proceeds from 36 200824320 to step 8 0 3 to receive the signal from the access terminal 2 . The program 833 executed by the access terminal 2! 3 receives the feedback in step 839 and processes the feedback as described below. First, if no feedback is received, in this embodiment, the program 8 3 3 loops back to step 8 3 q Φ 笙炷 g ^ y, waiting for feedback. If the feedback is received, the process proceeds to step 8 4 2 ' to determine if a coarse timing adjustment π or the heart has been received. If the _ rough timing adjustment command or the message system has been received, the coarse timing adjustment is implemented in step 8 4 5, the coarse timing adjustment may be an absolute or relative measurement, as described above. . In step 8 4 8 , the access terminal 2 i 3 determines whether or not _ a sequel, a timing falsification command, or a message system has been received. If a subtle timing adjustment command or message has been received, a fine timing adjustment is performed in step 8 $1. It should be understood that this subtle timing adjusts the blood content - a differential command or message. In this fine timing adjustment ^: The program 8 3 3 determines whether a power level adjustment command or Γ ^ has been received. If a power level adjustment command or message ', a breaks the reception, then in step 8 5 7 , the access adjusts the power level.丄d after adjusting for timing or power, in step 860, = 833 is more (four) the operating parameters of the receiving end 213 are first parameterized, and the program is repeated in step 839, ' or the base Feedback from the church processor 220.
