技术领域 FIELD

本申请总体涉及无线通信,更具体而言涉及确认和速率控制信道。 The present application relates generally to wireless communications, and more specifically to acknowledgment and rate control channels. 背景技术 Background technique

无线通信系统被广泛用于提供各种通信,诸如语音和数据。 Wireless communication systems are widely deployed to provide various types of communication such as voice and data. 典型的无线数据系统、或网络使多个用户能访问一个或多个共享资源。 A typical wireless data system, or network access to a plurality of users to one or more shared resources. 系统可用使用多种多址技术,诸如频分复用(FDM)、时分复用(TDM)、码分复用(CDM)和其它技术。 System may use a variety of multiple access techniques such as frequency division multiplexing (FDM), time division multiplexed (TDM), Code Division Multiplexing (CDM), and others.

示例性无线网络包括蜂窝式数据系统。 Exemplary wireless networks include cellular data systems. 以下是几个这样的例子:(1) "双模宽带扩频蜂窝系统的移动站一基站兼容性标准TIA/EIA-95-B" (IS-95标准)(2)由"第三代合作伙伴计划"(3GPP)机构提供的, 并包含在包括了第3GTS 25.211、 3GTS 25.212、 3GTS25,213和3GTS 25.214号文件的一组文件中的标准(W-CDMA标准),(3)由"第三代合作伙伴计划2" (3GPP2)机构提供的,并包含在"cdma2000扩频系统的物理层标准TR-45.5"的标准(IS-2000标准),(4)符合TIA/EIA/IS-856 标准(IS-856标准)的高数据速率(HDR)系统,和(5) IS-2000标准的修订版C,包括C.S0001C-C.S0006.C,并且相关文件(包括后来的修订版D提交)被称为lxEV-DV建议。 The following are several such examples: (1) "Dual-Mode Wideband Spread Spectrum Cellular System mobile station a Base Station Compatibility Standard TIA / EIA-95-B" (IS-95 standard) (2) by the cooperation "Third Generation partnership Project "(3GPP) provides a mechanism, comprising a first and included in the 3GTS 25.211, a group of files 3GTS 25.212, 3GTS25,213 3GTS 25.214 and number of the standard document (W-CDMA standard), (3)" on Three Generation partnership Project 2 "(3GPP2) agencies, and included in" physical layer standard for cdma2000 spread Spectrum systems TR-45.5 "standard (iS-2000 standard), (4) compliance with TIA / EIA / iS-856 standard (iS-856 standard) the high data rate (HDR) system, and (5) iS-2000 standard revision C, comprising C.S0001C-C.S0006.C, and related documents (including subsequent Revision D submission) is called lxEV-DV proposal.

在示例性系统中,IS-2000标准的修订KgD (目前正在研究中),移动台在反向链路上的发射由基站来控制。 In the exemplary system, IS-2000 Revision KGD standard (currently under investigation), the mobile station transmits on the reverse link is controlled by the base station. 基站可决定允许移动台发送的 The base station may decide to allow the mobile station transmitted

8最大速率或业务一导频比率(TPR)。 8 a maximum rate or traffic-pilot ratio (TPR). 当前建议的为两种控制机制:基于准许的控制机制和基于速率控制的控制机制。 The current recommendation is two control mechanisms: grant control mechanisms and control mechanisms based on rate control.

在基于准许的控制中,移动台向基站反馈关于移动台的发送能力、 数据缓冲器的大小、和服务质量(QoS)水平等的信息。 In the control based on the grant, the mobile station transmits feedback capability for the mobile station to the base station, the information of the data buffer size, and Quality of Service (QoS) level and the like. 基站监视来自多个基站的反馈并决定允许哪些移动台发送以及允许每个移动台的相应最大速率。 The base station monitors feedback from a plurality of base stations and a mobile station which determines the transmission permission and the corresponding maximum rate allowed for each mobile station. 这些决定通过准许消息传送给移动台。 These decisions to the mobile station via grant messages.

在基于速率控制的控制中,基站以受限制的范围调节移动台速率(即, 一个速率增加、无变化、和一个速率下降)。 Rate control based control, a base station in a limited range of adjusting the mobile station speed (i.e., a rate increase, no change, and a rate decrease). 调节命令通过使用简单的二进制速率控制比特或多值的指示符传送到移动台。 Control or adjustment command indicator bit value is transmitted to the mobile station by using a simple binary rate.

在移动台具有大量数据的全缓冲(foil buffer)的情形下,基于准许的技术和速率控制技术执行大致相同的操作。 The case having a large amount of data fully buffered (foil buffer) at the mobile station, based on the grant and rate control techniques perform substantially the same operation. 不计开销问题,在实际的流量模型的情况下准许方法可能能够更好地控制移动台。 Excluding the cost issue, grant method may be better able to control the mobile station in the case of actual flow model. 不计开销问题, 准许方法可能能够更好地控制不同的QoS流。 Excluding the cost issue, grant method may be better able to control different QoS streams. 两种类型的速率控制可以 Two types of rate control may

被区分开来,其包括给每个移动台单个比特的专用速率控制方法,和每扇区使用单个比特的公共速率控制。 It is distinguished, comprising a single bit to each mobile station dedicated rate control method, using a single bit per sector and a common rate control. 这两种方法的各种不同组合可能是 Various combinations of these two methods may be

将一速率控制比特分配给多个移动台。 The rate control bits are allocated to a plurality of mobile stations. 公共速率控制方法可能需要较少的开销。 Common rate control approach may require less overhead. 但是,当其与更专用的控制方案相比时可提供较少的对移动台的控制。 However, when it is compared with a more dedicated control scheme may provide less control over mobile stations. 在任意一个时刻当正在发送的移动台数目减小时,则公共速率控制方法和专用速率控制会变得彼此更相似一些。 At any one time when the number of the mobile station is transmitted is reduced, then the common rate control method and the dedicated rate control will become more similar to each other number.

基于准许的技术能够迅速地改变移动台的发射速率。 Grant based techniques can rapidly change the transmission rate of the mobile station. 然而如果存在连续的速率改变,仅仅基于准许的技术可能会遭受高开销的苦恼。 However, if there are changes at a continuous rate, based only on the licensed technology may suffer from high overhead distress. 类似地,纯粹的速率控制技术会在上升时期(ramp-uptimes)期间经受缓慢的上升时期和相等的或更高的开销。 Similarly, a pure rate control technique may be subjected to a slow rise times and equal or higher overhead during the rising period (ramp-uptimes).

这两种方法都不能既提供减小的开销又提供较大或快速的速率调整。 Both methods can not provide both reduced overhead and large or rapid rate to provide adjustment. 能够满足这种需要的方法的实例在于2004年2月17日提交的,题为"组合准许、确认、和速率控制命令"的第XX/XXX,XXX (第030525号代理文档)的美国专利申请中公开,该专利已被转让给本发明的受让人。 Examples of methods that can meet this need, 2004, filed February 17, entitled "The combination of grant, acknowledgment, and rate control command" of XX / XXX, XXX (Attorney Docket No. 030525), US Patent Application It is disclosed, which patent is assigned to the assignee of the present invention.

此外,还希望能在为控制信道上的相关命令维持令人满意的差错概率的同时,减小控制信道的数目。 In addition, we hope while maintaining a satisfactory probability of error for the associated commands on the control channel, reduce the number of control channels. 本领域内存在对以下系统的需求,这种系统提供了控制各个移动台以及移动台组的速率(或者对相应移动台的资源分配)的能力,而不会不当地增加信道计数。 This demand exists in the art for the system, such a system provides the ability to control the rate of mobile stations and each mobile station group (or the corresponding resource allocation of the mobile station), and will not count without increasing the local channel. 此外,还需要能够 In addition, the need to be able

9适应不同速率控制或确认命令的差错概率。 9 adapt to different error probability rate control or acknowledgment commands. 因此,本领域内存在对减小开销控制、发射的确认、和在必要时调节发射速率的能力的需要。 Thus, the memory required in the art to reduce overhead control acknowledgment, transmission, and the ability to adjust the transmission rate, if necessary.

发明内容 SUMMARY

本文公开的实施例解决了本领域内对扩展的确认/速率控制信道的需求。 Example embodiments disclosed herein addresses the art for an extended acknowledgment / rate control channel needs. 在一个实施方案中,确认命令和速率控制命令被组合起来以生成组合命令。 In one embodiment, the acknowledgment command and rate control command are combined to generate a combined command. 在另一个实施方案中,依照多个点的星座生成组合命令,其中每个点与由速率控制命令和确认命令组成的一对命令相对应。 In another embodiment, in accordance with a combination of a plurality of commands generated constellation points, where each point confirmation command and the control command consists of a command speed corresponds. 仍在另一个实施例中,该星座的各个点被设计成用来为各自的命令对提供期望的差错概率。 In still another embodiment, each of the points in the constellation are designed to provide the desired probability of error for the respective command. 仍在另一个实施方案中,公共速率控制命令与组合或专用速率控制命令一起发送。 In still another embodiment, the common rate control command or in combination with the dedicated transmission rate control command. 还提出了其它各种不同实施方案。 Also proposed other various embodiments. 这些实施方案具有减小开销同时向单个远程站和/或远程站组提供确认和速率控制的优点。 These embodiments have the advantage of reduced overhead while providing acknowledgment and rate control to single remote stations and / or the remote station group.

图1是可被设计成支持一个或多个CDMA标准和/或设计(例如, W-CDMA标准、IS-95标准、cdma2000标准、HDR规范、lxEV-DV系统)的无线通信系统100的图。 FIG 1 is may be designed to support one or more CDMA standards and / or designs (e.g., W-CDMA standard, IS-95 standard, cdma2000 standard, the HDR specification, lxEV-DV system) 100 of the wireless communication system of FIG. 在可选实施例中,系统100可附加地支持任意CDMA系统以外的无线标准或设计。 In an alternative embodiment, system 100 may additionally support wireless standard or design other than a CDMA system arbitrarily. 在示例性实施例中,系统100是lxEV-DV系统。 In an exemplary embodiment, the system 100 is a lxEV-DV system.

为了简明起见,图中只示出了系统100包括与两个移动台106通信的三个基站104。 For the sake of clarity, the figure shows only the system 100 includes a base station 106 and three mobile stations 104 communicating two. 基站和其覆盖区通常被整体称为"小区"。 The base station and its coverage area are commonly referred to as integral "cells." 在IS-95、 cdma2000或lxEV-DV系统中,例如,小区可包括一个或多个扇区。 In IS-95, cdma2000, or lxEV-DV systems, for example, a cell may include one or more sectors. 在W-CDMA规范中,基站的每个扇区和该扇区的覆盖区被称为小区。 In the W-CDMA specification, each sector of the base station and the sector coverage area is referred to as a cell. 如在此处使用,术语基站能够与术语接入点或节点B互换使用。 As used herein, the term base station can be used interchangeably with the terms access point or Node B interchanged. 术语移动台能够与术语用户设备(UE)、用户单元、用户站、接入终端、远程终端或其它本领域已知的相应术语互换使用。 The term mobile station to the term user equipment (the UE), subscriber unit, subscriber station, access terminal, remote terminal, or other corresponding terms known in the art interchangeably. 术语移动台包括了固定的无线应用。 The term mobile station includes a fixed wireless applications.

取决于正被实现的CDMA系统,每个移动台106可在任意给定时刻在前向链路上与一个(或者可能是多个)基站104通信,并可以依据移动台是否处于软切换而在反向链路上与一个或多个基站通信。 Depending on the CDMA system being implemented, each mobile station 106 may be at any given moment on the forward link with one (or possibly more) base stations 104 communicate, and may be based on whether the mobile station in soft handoff in communicate with one or more base stations on the reverse link. 前向链路(即,下行链路)指的是从基站到移动台的发射,而反向链路(即,上行链路)指的是从移动台到基站的发射。 The forward link (i.e., downlink) refers to a mobile station transmitted from the base station, and the reverse link (i.e., uplink) refers to the emission from the mobile station to the base station.

尽管此处描述的不同实施例意在提供用于支持反向链路发射的反向链路或前向链路信号,并且一些实施例可能非常适合反向链路发射的特性,但本领域的技术人员会理解到:移动台以及基站能够被配备成用来如此处所述的那样发射数据,并且本发明的各实施方案也能应用在那些情形中。 While various embodiments described herein are intended to provide support for the reverse link transmit reverse link or forward-link signals, and some embodiments may be well suited reverse link transmit characteristics, the present art in the art will appreciate that: a mobile station and a base station can be equipped to transmit data as used at the case, and various embodiments of the present invention can also be applied in those cases. 此处词语"示例性"仅仅表示"作为实例、例证、或起说明作用"。 Here the word "exemplary" is merely mean "as an example, instance, or illustrative purposes." 不必要把任意在此处被描述为"示例性"的实施例解释为比其它实施例更优选或更有益。 The optionally unnecessary described herein as "exemplary" embodiments be construed as preferred or advantageous over other embodiments.

lxEV-DV前向链路数据发射 LxEV-DV before transmitting to the data link

诸如lxEV-DV建议中描述的系统,系统100通常包括四类前向链路信道:开销信道、动态变化的IS-95和IS-2000信道、前向分组数据信道(F-PDCH)和一些备用信道。 System description proposed, such as lxEV-DV, the system 100 generally includes a first four forward link channel: overhead channels, dynamically varying IS-95 and IS-2000 channels, a forward packet data channel (F-PDCH), and some spare channel. 开销信道的分配变化地很慢;例如,它们可以数个月不发生变化。 Overhead channels allocated variably slowly; for example, they may not change for months. 典型地,它们在发生主网络配置的改变时才被改变。 Typically, they are changed only when the change occurs in the primary network configuration. 动态变化的IS-95和IS-2000信道在每次呼叫的基础上被分配,或者被用于IS-95或IS-2000版本OB的语音和分组业务。 Dynamic IS-95 and IS-2000 channels are allocated on a per call basis or are used for IS-95 or IS-2000 version OB voice and packet services. 典型地,在开销信道和动态变化的信道已经被指配之后剩余的可用基站功率被分配给F-PDCH,用于剩下的数据业务。 Typically, after the overhead channels and dynamically varying channels have been assigned the remaining available base station power is allocated to the F-PDCH, for remaining data services.

与IS-856标准中的业务信道相似的F-PDCH,被用于每次以能支持的最高速率向每个小区中的一个或多个用户发送数据。 And IS-856 standards are similar traffic channels F-PDCH, is used for each cell to transmit data to each of one or more users can be supported at the highest rate. 在IS-856中,当向移动台发射数据时,基站的整个功率和沃尔什函数的整个空间是可用的。 In IS-856, when transmitting data to a mobile station, and power throughout the entire space of Walsh functions are available to the base station. 然而,在lxEV-DV系统中, 一些基站功率和沃尔什函数的其中一些被分配给开销信道和现有的IS-95和cdma2000业务。 However, in lxEV-DV system, some base station power and some of the Walsh functions are allocated to overhead channels and existing IS-95 and cdma2000 services. 能够支持的数据速率主要取决于在用于开销信道、IS-95和IS-2000信道的功率和沃尔什代码已经被分配之后可用的功率和沃尔什代码。 Supports data rates depending on the power and Walsh codes for the overhead after the available channels, IS-95 and IS-2000 channels of power and a Walsh code has been assigned. 通过使用一个或多个沃尔什代码把F-PDCH上发送的数据扩展。 By using one or more Walsh codes to transmit data on the F-PDCH extended.

在lxEV-DV系统中,基站通常每次在F-PDCH上向一个移动台发射, 尽管一些用户可能正在使用小区内的分组业务。 In lxEV-DV system, each base station to a mobile station is usually transmitted on the F-PDCH, although some users may be using packet services in a cell. (也可以通过为两个用户调度发射并适当地为每个用户分配功率和沃尔什信道,来向两个用户发送。)基于一些调度算法为前向链路发射选择移动台。 (May transmit to two users by scheduling and appropriately distributing power and Walsh channels to each user to transmit to two users.) Scheduling algorithm based on some link transmission to the mobile station for the first selected.

在类似于IS-856或lxEV-DV的系统中,调度是部分地基于来自正在被服务的移动台的信道质量反馈进行的。 In similar to IS-856 or lxEV-DV system, scheduling is based in part on channel quality from the mobile stations being serviced in the feedback. 例如,在IS-856中,移动台估计前向链路的质量并计算预期能为当前条件保持的发射速率。 For example, in IS-856, the mobile station before the transmission rate is estimated and calculated is expected to maintain the quality of the link to the current conditions. 来自每个移动台的期望的速率被发射到基站。 Desired rate from each mobile station is transmitted to the base station. 调度算法可以,例如,选择支持相对较高的发射速率的发射的移动台,以便更有效地使用共享通信信道。 The scheduling algorithm may, for example, choose to support relatively high transmission rate transmitted by mobile stations in order to more efficiently use the shared communication channel. 作为另一个实例,在lxEV-DV系统中,每个移动台在反向链路质量指示信道(R-CQICH)上发射载波干扰比(C/I)的估计作为信道质量估计。 As another example, in lxEV-DV system, each mobile station in a reverse link channel quality indicator channel (R-CQICH) transmit the estimated carrier to interference ratio (C / I) estimate as the channel quality. 调度算法被用于确定用于发射的移动台,以及根据信道质量确定适当的速率和发射格式。 Scheduling algorithm is used to determine the mobile station transmits, and the appropriate rate and transmission format is determined according to channel quality.

如上所述,无线通信系统100可支持多个同时共享通信资源的用户, 诸如IS-95系统那样,可以偶尔将整个系统资源分配给一个用户,诸如IS-856系统那样,或者可以分摊系统资源以允许这两种类型的接入。 As described above, the wireless communication system 100 may support multiple users sharing the communication resource simultaneously, such as IS-95 system, the entire system can occasionally be a resource allocated to the user, such as IS-856 system, or may apportion system resources allow both types of access.

C/I测量是被用作信道估计的信道质量度量的实例,并且替代的信道质量度量可以在可选实施例中采用。 C / I measurement is used as a channel estimation channel quality metric examples, and alternate channel quality metrics can be employed in the embodiment in an alternative embodiment. C/I测量被传送到基站104中的发射子系统210,其实例将在以下参考图3做进一步详细说明。 C / I measurement is delivered to transmission subsystem 104, the base station 210, three examples of which are described in further detail below with reference to FIG.

发射子系统210通过反向链路传送C/I估计,在该反向链路上C/I估计将被传送到服务基站。 Transmit subsystem 210 via the reverse link transmitted C / I estimate over the reverse link C / I estimate to be transmitted to the serving base station. 注意的是,在本领域已知的软切换的情形中, 从移动台发射的反向链路信号可以被一个和多个并非服务基站的基站接收到,在此将这些基站称为非服务基站。 Note that, in the case of soft handover known in the art, the reverse link signal transmitted from a mobile station and a base station may be serving a plurality of base stations are not received, this will be referred to as non-serving base stations . 基站104中的接收子系统230 接收来自移动台106的C/I信息。 Receiving subsystem 230 receives the base station 104 in C / I information from mobile station 106.

基站104中的调度器(scheduler) 240用于确定是否应该以及怎样把数据发送到服务小区的覆盖区内的一个和多个移动台。 The base station scheduler 104 (scheduler) 240 for determining whether and how to transmit data to a serving cell coverage area and a plurality of mobile stations. 在本发明的范围 In the scope of the invention

内可以采用任意类型的调度算法。 Within any type of scheduling algorithm can be employed. 一个实例在1997年2月11日提交的题为"前向链路速率调度的方法和装置"的美国专利号08/798,951中公开,该专利被转让给本发明的申请人。 In one example, "Method and Apparatus front link rate scheduling" in U.S. Patent No., entitled, filed February 11, 1997, 08 / 798,951 disclosure, which patent is assigned to the assignee of the present invention.

在示例的lxEV-DV实施例中,当从某个移动台接收到的C/I测量指示数据能够以一定速率被发送时,为前向链路发射选择移动台。 In the example lxEV-DV embodiment, a mobile station is received from one to the C / I measurement instruction data can be transmitted at a certain rate, the mobile station is selected prior to transmission link. 就系统容量而论,选择能使得共享通信资源总是以其最大可支持的速率被利用的目标移动台是有益的。 On system capacity is concerned, selection enables shared communication resource is always its maximum rate that can be supported by the use of the target mobile station is beneficial. 这样,典型的被选的目标移动台可以是具有最大的报告的C/I的移动台。 Thus, the typical target mobile station selected may be the mobile station C / I has the greatest reported. 其它因素也可以被引入到调度决定中。 Other factors may also be incorporated in a scheduling decision. 例如, 可能已经对不同用户做出了服务保证的最小质量。 For example, it may have made a minimum guaranteed quality of service to different users. 可以是具有相对较低的报告的C/I的移动台被选择用来发射,以维持到那个用户的最小数据传递速率。 C may have a relatively lower reported / I of the mobile station selected to transmit, to maintain a minimum data transfer rate to that user. 可以是不具有最大的报告的C/I的移动台被选择用来发射, 以在^f有用户当中维持一定的公平性标准。 The mobile station C / I may not have a maximum number of reports is selected to emit, among the users to maintain certain fairness criteria ^ f.

在示例的lxEV-DV系统中,调度器240为那个发射确定哪个移动台来发送、以及数据速率、调制格式和功率水平。 In the example lxEV-DV system, scheduler 240 determines which mobile station transmitter that transmits, as well as the data rate, modulation format, and power level. 在可选实施例中,诸如IS-856系统中,例如,可支持的速率/调制格式决定可以在移动台处基于移动台处测量的信道质量做出,并且发送格式可以被发送到C/I测量场所中的服务基站。 In an alternative embodiment, such as IS-856 system, for example, a supportable rate / modulation format decision can be made at the mobile station based on channel quality measured at the mobile station, and transmission format may be transmitted to the C / I measuring the serving base station properties. 本领域的技术人员将认识到,在本发明的范围内可以采用对可支持速率、调制格式、功率水平等的多种组合。 Those skilled in the art will recognize that, within the scope of the present invention may be employed various combinations of supportable rates, modulation formats, power levels, etc. 此外,尽管在此处所述的不同实施例中,调度任务是在基站中执行的,但在可选实施例中,调度处理的一些部分和全部可以在移动台进行。 Furthermore, although in various embodiments described herein the scheduling tasks are performed in the base station, but in alternative embodiments, some portions and all of the scheduling process may be performed in the mobile station.

调度器240指引发射子系统250使用选定的速率、调制格式、功率水平等在前向链路上向选定的移动台发送。 Guidelines transmit scheduler 240 subsystem 250 using the selected rate, modulation format, power level, etc. sent forward to the selected mobile station on the forward link.

在示例性实施例中,控制信道或F-PDCCH上的消息与数据信道或F-PDCH上的数据一起发送。 In an exemplary embodiment, data is transmitted together on the F-PDCH message on the data channel or control channel, or F-PDCCH. 控制信道能被用于识别移动台对F-PDCH 上的数据的接收,还能识别通信会话期间其它有用的通信参数。 The control channel can be used to identify the mobile station receives the data on the F-PDCH, but also identifying other communication parameters useful during the communication session. 移动台应该在F-PDCCH指示该移动台是发射的目标时接收和解调来自F-PDCH 的数据。 The mobile station should be in the F-PDCCH indicates that mobile station is to receive and demodulate data from the F-PDCH transmission target. 移动台在接收到这样的数据之后,利用指示发射的成功或失败的消息来在反向链路上做出响应。 After the mobile station receives such data, transmitted using the indicating success or failure message responds on the reverse link. 本领域内已知的重传技术被广泛用在数据通信系统中。 Known in the art retransmission techniques are widely used in data communication systems.

移动台可以与多于一个的基站通信, 一种已知的情况为软切换。 The mobile station may be more than one base station communicating with a known case of soft handover. soft

15(或一个基站收发子系统(BTS))的多个扇区,被已知为更软切换(softer handoff),以及多个基站的扇区。 15 (or one Base Transceiver Subsystem (the BTS)) a plurality of sectors, is known as softer handover (softer handoff), and a plurality of base station sectors. 软切换中的基站扇区通常被存储在移动台的活动集中。 Base station sectors in soft handoff are generally stored in a concentrated active mobile station. 在通信资源被同时共享的系统中,诸如IS-95、 IS-2000,或lxEV-DV系统的对应部分中,移动台可以组合从活动集的所有扇区发送的前向链路信号。 In the communication resources are simultaneously sharing system, such as IS-95, a corresponding portion of IS-2000, or lxEV-DV system, the mobile station may combine forward link signals transmitted from all sectors in the active set. 在诸如IS-856这样的纯数据(data-only)系统中,或在IxEV-DV系统的相应部分中,移动台接收来自活动集中的一个基站,服务基站(根据诸如C.S0002.C标准中所述的算法那样的移动台选择算法确定的)的前向链路信号。 IS-856, such as such pure data (data-only) system, or in the corresponding section IxEV-DV system, the mobile station receives a base station, a serving base station from the active set (in accordance with the standard, such as C.S0002.C before the mobile station selection algorithm as the algorithm determining) a signal to the link. 以下将进一步详细描述的其它前向链路信号也可以从非服务基站接收到。 Other prior to the following described in further detail can also be received from non-serving base station forward link signal.

来自移动台的反向链路信号可以在多个基站处接收到,并且通常为活动集中的基站维持反向链路的质量。 Reverse link signals from the mobile station may be received at multiple base stations, and the quality of the reverse link is generally maintained for the active base station set. 在多个基站处接收到的反向链路信号可以被组合起来。 The reverse link signals received at multiple base stations may be combined. 通常,软组合来自位置不同的基站的反向链路信号将需要相当大的网络通信带宽以及非常小的延迟,因此以上列出的示例性系统不支持这种组合。 In general, soft combining reverse link signals from different locations of base stations would require significant network communication bandwidth and very little delay, so the example systems listed above do not support this combination. 在更软切换中,在单个BTS中的多个扇区处接收到的反向链路信号能够被组合起来,而无需网络信令。 In softer handover, a plurality of sectors in a single BTS at the received reverse link signals can be combined without network signaling. 尽管在本发明的范围内可以采用任意类型的反向链路信号组合,但在上述的示例性系统中,反向链路功率控制维持质量以使反向链路帧能够在一个BTS (交换分集switching diversity)处被成功解码。 Although within the scope of the present invention, any type of reverse link signal combining may be employed, but in the exemplary system described above, reverse link power control is maintained so that the quality of a reverse link frames can be the BTS (switching diversity switching diversity) at the decoded successfully.

反向链路数据发射也可以在系统100中执行。 Reverse link data transmission may be performed in the system 100. 描述的接收和发射子系统210-230和250可以被用于在前向链路上发送控制信号,以指引反向链路上的数据发射。 Reception and transmission subsystems 210-230, and 250 as described may be used to send control signals to the front link, guidance data on the reverse link transmit. 移动台106也可以在反向链路上发送控制信息。 Mobile station 106 may transmit control information on the reverse link. 与一个或多个基站104通信的各个移动台106可以接入共享的通信资源(即,反向链路信道,其可以被可变地分配如在lxEV-DV中一样,或者可以被固定分配如在IS-856中一样),以适应各种接入控制和速率控制技术,其实例将在以下详细解释。 , Which may be variably allocated, as in lxEV-DV with each of the one or more mobile stations 106 may access the shared communication resource (i.e. the reverse link channel 104 communicates with a base, such as fixed or may be assigned as in the IS-856), to accommodate various access control and rate control techniques, examples of which will be explained in detail hereinafter. 调度器240可以被用于确定反向链路资源的分配。 The scheduler 240 may be assigned reverse link resources for determining. 以下将详细说明示例性的对反向链路数据通信的控制和数据信号。 It will be described in detail an exemplary control and data signals for reverse link data communication.

在一些情况下,反向链路容量是干扰受限的。 In some cases, reverse link capacity is interference limited. 基站依照各种不同移动台要求的服务质量(QoS)把可用的反向链路通信资源分配给移动台, 以有效地利用资源从而使吞吐量最大化。 The base station in accordance with a variety of different mobile stations required quality of service (QoS) of the available reverse link communication resources allocated to the mobile station, efficient use of resources to maximize throughput.

最大化对反向链路通信资源的利用包括几个因素。 Maximize the use of the reverse link communication resource involves several factors. 一个要考虑的因素是从各种不同移动台发射的被调度的反向链路的混合,其中每个移动台可以在任意给定时刻经受变化的信道质量。 Factor to consider is the mix of scheduled reverse link transmitted from a different mobile station, wherein the channel quality of each mobile station may be subject to change at any given time. 为了增加总的吞吐量(小区中所有移动台发射的总计数据),希望能在无论何时存在要发送的反向链路数据时,整个反向链路都能被全部使用。 To increase overall throughput (the total of all mobile stations transmit data in the cell), in the hope that whenever the presence of the reverse link data to be transmitted, the entire reverse link can be fully utilized. 为了填满可用的容量,移动台可以被准许能以它们可支持的最大速率接入,并且附加的移动台可以被准许直到达到容量为止。 To fill the available capacity, mobile stations may be granted access to them may be able to support the maximum rate, and additional mobile stations may be granted until capacity is reached so far. 基站在决定哪个移动台要调度时可以考虑的一个因素是,每个移动台能够支持的最大速率和每个移动台要发送的数据数量。 A factor when deciding which base station to the mobile station scheduling may be considered that the number of data each mobile station is capable of supporting the maximum rate each mobile station to be transmitted. 可以选择能够有更高的吞吐量的移动台,用来取代信道不支持该更高的吞吐量的可替换移动台。 You may be selected to have a higher throughput of the mobile station, to replace the channel does not support the higher throughput alternative mobile station.

另一个要考虑的因素是每个移动台要求的服务质量。 Another factor to consider is that each mobile station quality of service required. 尽管允许因为希望信道会改进而延迟对一个移动台的接入,而选择处境更好的移动台, 不是最理想的移动台可能需要被准许接入以满足最低服务质量保证。 Despite the hope that the channel will improve because of delayed access to a mobile station, and the choice situation better mobile station, the mobile station is not optimal may need to be granted access to meet minimum quality of service guarantees allowed. 这样,调度后的数据吞吐量可能不是绝对的最大值,而是考虑到信道条件、 可用的移动台发射功率、和服务需求后的最大值。 Thus, the data throughput scheduled may not be the absolute maximum, but taking into account the channel conditions, available mobile station transmit the maximum power, and service requirements. 对于任意配置,能减小选定的混合的信号噪声比是令人期望的。 For any configuration, can reduce the signal to noise ratio is selected mixed desirable.

以下描述了各种不同的调度机制,其用于允许移动台在反向链路上发送数据。 The following describes a variety of scheduling mechanisms for allowing the mobile station to transmit data on the reverse link. 一类反向链路发射包括移动台为了在反向链路上发射做出请求。 A class including a mobile station reverse link transmit on the reverse link to transmit a request is made. 基站做出是否能该请求提供资源的确定。 Whether the request can be made to determine the base station providing the resources. 准许可以被做出以允许该发射。 Pets can be made to allow the transmission. 移动台和基站之间的这种握手在反向链路数据能被发射以前引入延迟。 Such base stations between the mobile station and the reverse link data handshake can introduce a delay before transmitting. 对于某些种反向链路数据,该延迟可能是可接受的。 For some types of reverse link data, the delay may be acceptable. 其他类型可能会对延迟更为敏感,而以下详细说明了反向链路发射的可选技术,其用于减轻延迟。 Other types may be more sensitive to delay, and the following detailed description of the reverse link transmission alternative technique for mitigating delay.

此外,反向链路资源被消耗用于作出对发射的请求,而前向链路资源被消耗用于响应该请求,即发射一个准许。 In addition, reverse link resources are consumed for making a request for transmission, and the front link resources are consumed for the response to the request, i.e. transmit a grant. 当移动台的信道质量较低时,即低几何学或迅速衰减时,在前向链路上为到达移动台所需的功率可能会相对较高。 When the mobile station channel quality is low, i.e. low geometry or decay rapidly, as the forward link power required to reach the mobile station may be relatively high to. 以下详细说明了用于减少反向链路数据发射所需的请求和准许的数目或所需发射功率的各种技术。 Various techniques are detailed below to reduce the reverse link data transmission request and the required or desired number of permitted transmit power.

为了避免请求/准许握手引入的延迟,以及为了节约为支持它们所需的前向和反向链路资源,而支持自主的反向链路发射模式。 In order to avoid request / grant handshake delay introduced, to support and to conserve the forward and reverse link resources they need, and support autonomous reverse link transmission mode. 移动台可以以有限的速率在反向链路上发送数据,而不用作出请求或等待准许。 The mobile station may transmit data on the reverse link at a limited rate, without making a request or waiting for permission.

能够根据准许来修改或者自主地(无需准许的开销)修改正在发送的移动台的发射速率,也可能是可取的。 Autonomously or can be modified (without grant overhead) to modify transmission rate of the mobile station is transmitting, it may be desirable according to the grant. 为了完成这种功能,速率控制命令可以与自主的调度和基于请求/准许的调度一起被实现。 To accomplish this function, the rate control command and may customize the scheduling based on the request / grant scheduling is implemented together. 例如, 一组命令可包括增大、减小和维持不变发射的当前速率的命令。 For example, a set of commands may include increasing, decreasing, and maintaining constant emission current rate command. 这样的速率控制命令可以对每个移动台是单独可寻址的,或者可以对一组移动台是可寻址的。 Such rate control command for each mobile station can be individually addressable, or a group of mobile stations may be addressable. 以下将进一步详细说明各种示例性速率控制命令、信道、和信号。 It will be described in further detail various exemplary rate control commands, channels, and signals.

基站把一部分反向链路容量分配给一个或多个移动台。 The base station allocates a portion of the reverse link capacity to one or more mobile stations. 被准许接入的移动台被提供以最大的功率水平。 Mobile station is granted access is provided to the maximum power level. 在此处说明的示例性实施例中,通 In the exemplary embodiment illustrated herein, by

过利用业务导频(T/P)比率来分配反向链路资源。 Business by utilizing the pilot (T / P) ratio to allocate reverse link resources. 由于每个移动台的导频信号经由功率控制被自适应地控制,规定T/P比率指示在反向链路上发射数据能够使用的功率。 Since the pilot signal of each mobile station via the power control frequency is adaptively controlled, specified T / P ratio indicates the transmission power data can be used on the reverse link. 基站可以对一个或多个移动台作出特定准许, 指示特定于每个移动台的T/P值。 The base station may make specific to permit one or more mobile stations, indicating a specific mobile station to each T / P ratio. 基站还可以对已经请求过接入的剩余的移动台作出公共准许,指示允许那些剩余的移动台发射的最大T/P值。 The base station may also make a common grant to the remaining mobile station has requested an access, indicating a maximum T allowing those remaining mobile stations to transmit / P ratio. 自主的和调度的发射、单独的和公共准许、以及速率控制将在以下被详细说明。 Autonomous and scheduled transmission, individual and common grant, rate control, and will be described in detail below.

本领域内已知各种调度算法,并且更多的算法仍将被开发出来,这些算法能够用于依照某些因素来确定用于准许的各种特定和公共的T/P 值以及想得到的速率控制命令,其中这些因素包括:注册的移动台的数目、移动台自主发射的可能性、尚未回复的请求的数目和大小、预期的对准许的平均响应、和任意个其他因素。 Variety of scheduling algorithms known in the art, and still more algorithms are developed, these algorithms can be used to determine the various specific and common T / P values ​​for grants as well as the rate in accordance with certain factors conceivable control command, wherein the factors include: the number of registered mobile stations, the possibility of the mobile station autonomously transmitted, the number and size of the request have not responded, the average response to grants desired, and any number of other factors. 在一个实例中,基于服务质量的移动台的集合的可获得的吞吐量,作出选择。 In one example, based on a certain set of available quality of service of the mobile station, to make a choice. 在2003年8月28日提交的题为"SYSTEM AND METHOD FOR A TIME-SCALABLE PRIORITY-BASED SCHEDULER" In 2003, entitled, filed August 28 "SYSTEM AND METHOD FOR A TIME-SCALABLE PRIORITY-BASED SCHEDULER"

("用于时间可縮放的基于优先级的调度器的系统和方法")的待审的美国专利号10/651,810中公开了一种示例性调度技术,该专利被转让给本专利的受让人。 ( "System and method for priority-based scheduler for the temporal scalability"), copending U.S. Patent No. discloses an exemplary scheduling technique 10 / 651,810, which is assigned to the assignee of the present patent people. 附加参考包括题为"METHOD AND APPARATUS FOR REVERSE LINK RATE SCHEDULING"("用于反向链路速率调度的方法和装置")的美国专利号5,914,950,和题目也为"METHOD AND APPARATUS FOR REVERSE LINK RATE SCHEDULING "("用于反向链路速率调度的方法和装置")的美国专利号5,923,650,这两个专利都被转让给本专利的受让人。 Additional references include, entitled "METHOD AND APPARATUS FOR REVERSE LINK RATE SCHEDULING" ( "Method and apparatus for reverse link rate scheduling") U.S. Patent No. 5,914,950, and also entitled "METHOD AND APPARATUS FOR REVERSE LINK RATE SCHEDULING "(" method and apparatus for reverse link rate scheduling ") U.S. Patent No. 5,923,650, both patents are assigned to the assignee of the present patent.

移动台可以使用一个或多个子分组来发送数据的分组,其中每个子分组包含全部的分组信息(每个子分组不必要被完全相同地编码,因为各种编码或冗余可以在各个子分组中使用)。 The mobile station can use one or more sub packets transmitted data packet, wherein each subpacket comprises the entire packet information (each subpacket is unnecessary encoded identically, as various encoding or redundancy may be used in the respective sub-packet ). 可以利用重传技术来保证可靠的发射,例如自动重发请求(ARQ)。 Retransmission techniques may be utilized to ensure reliable transmission, for example Automatic Repeat reQuest (ARQ). 这样,如果第一个子分组被无差错地接收到(通过使用CRC,例如),则向移动台发送肯定性确认(ACK), 并且将不发送附加的子分组(回想到,每个子分组以一种形式或另一种形式包括完整的分组信息)。 Thus, if the first subpacket is received without error (through use of the CRC, for example), then transmits positive acknowledgment (ACK) to the mobile station, and will not send additional subpackets (recall that each subpacket to one form or another form comprises a complete packet information). 如果第一个子分组没被正确接收到,则向移动台发送否定确认信号(NAK),并且将发送第二个子分组。 If the first subpacket is not received correctly, the mobile station sends a negative acknowledgment signal (NAK), and sends the second subpackets. 基站能够组合两个子分组的能量并试着去解码。 The base station can combine the energy of the two subpackets and try to decode. 该处理可以被重复不确定次,尽管通常指定子分组的最大数目。 This process may be repeated uncertain times, although generally designated maximum number of subpackets. 在此处说明的示例性实施例中,最多可以发送四个子分组。 In the exemplary embodiment illustrated herein, up to four subpackets may be transmitted. 这样,由于附加的子分组被接收到,正确接收的可能性会增大。 Thus, due to the additional sub packet is received, it will increase the likelihood of correct reception. 以下具体说明的是用于组合ARQ响应、速率控制命令和准许的各种方式,这些方式能以可接受的开销水平对发射速率提供所期望水平的灵活性。 The following detailed description is for the combination of ARQ response, and rate control command permits a variety of ways which can be at an acceptable cost level of the desired level of flexibility to the transmission rate.

如刚刚描述的,在决定是使用自主传送以用低等待时间发送数据还是请求更高的数率传送并等待公共的或特定的准许中,移动台可以为等待时间权衡吞吐量。 As just described, in deciding whether to use autonomous transfer to transmit data or a request for a higher data rate transfer and waiting for a common or specific grant, a mobile station may trade-off throughput latency low latency. 此外,对于给定的T/P,移动台可以选择数据速率以适应等待时间或吞吐量。 In addition, for a given T / P, the mobile station may select a data rate to suit latency or throughput. 例如,具有相对较少的比特要发送的移动台可以决定,低等待时间是可取的。 For example, a mobile station with relatively few bits for transmission may decide that low latency is desirable. 对于可用的T/P (在此实例中可能为自主发射最大值,但也可能是特定的或公共的准许T/P),移动台可以选择这样的速率和调制格式,以使基站正确接收第一子分组的可能性较高。 For the available T / P (in this example the maximum emission may be independent, but may also be specific or common grant T / P), the mobile station may select a rate and modulation format, so that the base station correctly receiving the first the higher the possibility of a sub-packet. 尽管在必要时可以利用重传,也可能此移动台将能够在一个子分组中发送 Despite the availability of retransmission, when necessary, the mobile station may be capable of transmitting a sub-packet

它的数据比特。 Its data bits. 在此处说明的各种示例性实施例中,每个子分组在5ms 内发送。 In various exemplary embodiments described herein, each subpacket transmitted in the 5ms. 因此,在此实施例中,移动台可以进行立即自主发射,其可能在5ms的间隔之后在基站处被接收到。 Thus, in this embodiment, the mobile station can immediately transmit autonomously embodiment, which may be received at the base station after the interval of 5ms. 应注意的是,可替代地,移动台可以使用附加子分组的可用性来增加对于给定的T/P发送的数据数量。 It is noted that, alternatively, the mobile station may use the availability of additional subpackets to increase the amount of data for a given T / P transmitted. 所以,移动台可以选择自主传送以减小与请求和准许有关的等待时间, 并可以额外地为特定T/P权衡吞吐量,以最小化所需子分组的数目(从而减少等待时间)。 Therefore, the mobile station may select autonomous transfer to reduce latency associated with requests and grants, and may additionally be a particular T / P throughput tradeoff to minimize the required number of sub-packet (thereby reducing latency). 即使全数目的子分组被选择,对于相对较小的数据传送来说,自主传送也将比请求和准许的等待时间更少。 Even full subpacket is selected object, for relatively small data transfers, it can autonomously transmit latency than request and grant less. 本领域的技术人员将会认识到,随着要发送的数据数量的增长,请求发射多个分组,通过切换到请求和准许模式可以减小整个等待时间,因为请求和准许的性能损失将最终被多个分组的更高的数据速率带来的增加的吞吐量所抵消。 Those skilled in the art will recognize that, as the number of data to be transmitted increase, request to transmit multiple packets, the overall latency may be reduced by switching to a request and grant mode, performance loss because the request and grant will eventually be bringing a plurality of packets of a higher data rate increase in a certain offset. 以下将利用能与各种T/P分配关联的发射速率和格式的示例性集合进一步详细说明这个处理。 The following will use this process can be described in more detail with various T exemplary set of transmission rate and format / distribution associated with P.

反向链路数据发射 The reverse link data transmission

反向链路设计的一个目标是,只要存在反向链路数据要发送就把基站处的热噪声增加量(Rise-over-Thermal) (RoT)保持相对恒定。 A design goal of a reverse link, as long as the presence of reverse link data to be transmitted to increase the amount of thermal noise (Rise-over-Thermal) (RoT) at the base station relatively constant put in. 反向链路数据信道上的发射以三种不同模式来控制- Transmitting reverse link data channel is controlled in three different modes -

自主发射:这种情况用于要求低时延的业务。 Independent emission: This case requires a low delay. 移动台被允许以不超 The mobile station is not allowed to exceed

过某个发射速率的速率立即发射,该发射速率由服务基站(即,移动台把它的信道质量指示符传送到的那个基站)确定。 A transmission rate over the rate of emission immediately, by the serving base station of the transmission rate (i.e., the mobile station channel quality indicator that is transmitted to that base station) is determined. 服务基站也被称为调度基站或准许基站。 The serving base station is also called scheduling grant or base station. 对于自主发射的最大允许发射速率可以由服务基站动态地基于系统负载、拥塞等来进行信号通知。 The maximum allowed transmission rate for autonomous transmission may be dynamically based on system load, congestion, etc. signaled by the serving base station.

调度发射:移动台发送对其缓冲器大小、可用功率和可能存在的其他参数的估计。 Scheduled transmission: the mobile station sends an estimate of their buffer size, available power, and other parameters may be present. 基站确定何时允许移动台发射。 The base station determines when the mobile station allowed to transmit. 调度器的目标是限制同时发射的数目,这样就减小了移动台之间的干扰。 Target scheduler is to limit the number of simultaneously transmitted, thus reducing the interference between mobile stations. 调度器可以试着使小区之间的区域中的移动台以较低的速率发射以减小对相邻小区的干扰, Scheduler may try to cause a mobile station in a region between cells transmit at lower rates so as to reduce interference to neighboring cells,

并试着紧密地控制RoT以保护R-FCH上的语音质量、确认(R-ACKCH) 和R-CQICH上的DV反馈,以及系统的稳定性。 And try to protect the tightly control RoT to voice quality on R-FCH, confirm the stability of the DV feedback (R-ACKCH), and R-CQICH, and the system. 速率控制发射:无论移动台是被调度地(即,被准许地)发射还是自主发射,基站都可以通过速率控制命令调节发射速率。 Controlling transmission rate: whether the mobile station is scheduled (i.e., is permitted to) autonomous transmission, or transmit, the base station may adjust the transmission rate via rate control commands. 示例性速率控制命令包括增加、减小、或保持当前速率。 Exemplary rate control commands include increasing, reducing or holding the current rate. 可以包括附加的命令,用来规定如何实现速率改变(即,增加或减小的数量)。 It may include additional command for specifying how the change rate (i.e., increasing or decreasing the number). 速率控制命令可以是随机性的或是确定性的。 Rate control commands can be random or deterministic.

在此描述的各个实施例包含了一个或多个被设计成用来改善无线通信系统的反向链路的吞吐量、容量和整个系统性能的特征。 In each of the embodiments described herein contain one or more embodiments are designed to improve wireless communication system according to the reverse link throughput, capacity, and overall system performance characteristics. 仅仅为了说明性目的,描述了lxEV-DV系统中的数据部分,特别是对增强型反向补充信道(R-ESCH)上的各个移动台的发射的优化。 For illustrative purposes only, the data portion is described lxEV-DV system, in particular to optimize each mobile station transmitted on the supplemental channel (R-ESCH) for enhanced reverse. 此章节中详细说明了在一个或多个示例性实施例中使用的各种前向和反向链路信道。 This section details the various forward and reverse link channels used in one or more exemplary embodiments. 这些信道通常是通信系统中使用的信道的子集。 These channels are generally a subset of the channels used in a communication system.

图4说明了用于反向链路数据通信的数据和控制信号的示例性实施例。 FIG 4 illustrates an exemplary embodiment of data and control signals for reverse link data communication. 移动台106被显示正在通过各种信道进行通信,每个信道都连接到一个或多个基站104A-104C。 The mobile station 106 is shown is communicating over various channels, each channel connected to one or more base stations 104A-104C. 基站104A被标记为调度基站。 The base station 104A is labeled as the scheduling base station. 其它基站104B和104C是移动台106的活动集的一部分。 Other base stations 104B and 104C are part of the active set of mobile station 106. 显示有四种类型的反向链路信号和四种类型的前向链路信号。 Forward link signal is displayed four types of reverse link signals and four types of the former. 它们将在以下被描述。 They will be described below.

R-REQCH R-REQCH

反向请求信道(R-REQCH)被移动台用于向调度基站请求数据的反向链路发射。 A reverse request channel (R-REQCH) is a mobile station for the reverse link scheduling request to the base station to transmit data. 在示例性实施例中,这些请求是对在R-ESCH上发射的请求(将在以下做进一步详细说明)。 In an exemplary embodiment, the request is a request transmitted on the R-ESCH (will be further explained in detail below). 在示例性实施例中,R-REQCH上的请求包括移动台能够支持的T/P比率、根据正在发生改变的信道条件的变量、和缓冲器大小(即,等待发射的数据的数量)。 In an exemplary embodiment, a request on the R-REQCH includes a mobile station capable of supporting the T / P ratio, variable according to the channel condition changes taking place, and the buffer size (i.e., number of wait data transmitted). 该请求可以为等待发射的数据指定服务质量(QoS)。 The request may specify the quality of service (QoS) of data waiting for transmission. 要注意的是,移动台可以具有为移动台指定的单个QoS水平,或者可替换地,为不同类型的服务选项指定的不同的QoS水平。 It is noted that, the mobile station may have a single QoS level specified for the mobile station, or alternatively, designated for different types of service options different QoS levels. 高层协议可以为各种数据服务指示QoS、或所期望的其它参数(诸如等待时间或是吞吐量要求)。 Layer protocols may indicate various data services QoS, or other desired parameters (such as latency or throughput requirements). 在可替换实施例中,与其他反向链路信号结合使用的反向专用控制信道(R-DCCH),诸如反向基础信道(R-FCH)(例如用于语音服务),可被用于传送接入请求。 In the reverse dedicated control channel (R-DCCH) an alternative embodiment, in conjunction with other reverse link signals, such as a reverse fundamental channel (R-FCH) (used for voice services, for example), may be used transmit an access request. 通常, 接入请求可能被描述为包括逻辑信道,即,反向调度请求信道(R-SRCH), 其可以被映射到诸如R-DCCH这样的任意现存的物理信道上。 In general, access requests may be described as comprising a logical channel, i.e., reverse scheduling request channel (R-SRCH), which may be mapped to any such existing R-DCCH, such as physical channels. 示例性实施例能向后兼容诸如IS-2000版本C这样的现存的CDMA系统,而R-REQCH是能在没有R-FCH或R-DCCH的情况下采用的物理信道。 Exemplary embodiments backward compatible such as IS-2000 Revision C of such existing CDMA system, the R-REQCH is a physical channel can be employed in the absence of R-FCH or s R-DCCH case. 为了清楚起见,R-REQCH被用于描述此处实施例描述中的接入请求信道, 尽管本领域的技术人员将很容易把该原则扩展到任意类型的接入请求系统中,无论接入请求信道是逻辑的还是物理的。 For clarity, R-REQCH is used to describe the embodiments described in the access request channel in embodiment herein, although those skilled in the art will readily extend the principles to any type of access request system, whether the access request channel is logical or physical. R-REQCH可以是断开的, 直到请求被需要时才被选通,这样就减小了干扰并节约了系统容量。 R-REQCH may be turned off until a request is needed, by the gate, thus reducing interference and conserve system capacity.

在示例性实施例中,R-REQCH具有12个输入比特,这些比特包括以下比特:用于指定移动台能够支持的最大RE/SCH T/P比率的4个比特,用于指定移动台的缓冲器中的数据数量的4个比特,和用于指定QoS 的4个比特。 In an exemplary embodiment, R-REQCH has 12 input bits that include the following bits: four bits for designating the mobile station can support a maximum RE / SCH T / P ratio for the mobile station to specify the buffer an amount of data of 4 bits, and for 4 bits to specify the QoS. 本领域的技术人员会认识到,在可选实施例中可以包含任意数目的比特和其他各种字段。 Those skilled in the art will recognize that in alternative embodiments may include any number of bits and various other fields.

F-GCH F-GCH

前向准许信道(F-GCH)从调度基站发射到移动台。 Before transmitting to grant channel (F-GCH) from the scheduling base station to the mobile station. F-GCH可以包括多条信道。 F-GCH may include a plurality of channels. 在示例性实施例中,采用公共F-GCH来作出公共准许,而一条或多条单独F-GCH信道被利用用于作出单独准许。 In an exemplary embodiment, a common F-GCH employed to make a common grant, and one or more individual F-GCH channels are utilized to make individual grant. 由调度基站响应一个或多个来自一个或多个移动台的在它们各自的R-REQCH上的请求作出准许。 A response by the scheduling base station or a plurality of mobile stations from one or more requests on their respective R-REQCH to the grant. 准许信道可以被标注为GCHX,其中下标x标识信道编号。 Grant channel may be marked as GCHX, where the subscript x identifies the channel number. 信道编号O可以被用于指示公共准许信道。 O channel number may be used to indicate the common grant channel. 如果N个单独信道被采用,则下标x可以在1到N的范围内变化。 If N individual channels are employed, the subscript x may vary within the range 1 to N.

可以对一个或多个移动台作出单独准许,其中每个单独准许允许标识的移动台以指定的T/P比率或更低的比率在R-ESCH上发射。 Individual grant may be made to one or more mobile stations, wherein each individual grant allows the mobile station to identify the T / P ratio or below the specified ratio transmitted on R-ESCH. 在前向链路上作出准许自然将引入使用若干前向链路容量的开销。 To permit the forward link will naturally introduced into the overhead of using a plurality of forward link capacity. 这里详细说明了用于减轻与准许有关的开销的各种选项,根据此处的原则,其他选项对本领域的技术人员来说也将会很明显。 Here a detailed description of the various options for mitigating the overhead associated with the grant, according to the principle here, other options also will be apparent to those skilled in the art.

一个需要考虑的事项是各移动台将处于不同情况中,每个移动台经历变化的信道质量。 A considerations that each mobile station in different situations, each mobile station subjected to the channel quality changes. 这样,例如,具有较好的前向和反向链路信道的高几何性的移动台可能需要较低的功率用于准许信号,并且可能能够利用髙数据速率,因此对于单独准许是可取的。 Thus, for example, having a good forward and reverse link channel high geometry mobile station may require a lower power for grant signal, and may be able to use data rate Gao, so to permit the individual is desirable. 低几何性的移动台,或者正经历较快衰落的移动台,可能需要明显更多的功率用于可靠地接收单独准许。 Low geometry mobile station, or is undergoing rapid fading mobile station, may require significantly more power to receive individual grant reliably. 这样的移动台对于单独准许来说就可能不是最好的候选。 Such a mobile station is allowed for individual might not be the best candidate. 用于这种 For this

25移动台的公共准许,将在以下进行详细说明,可以较少地耗费前向链路开销。 Public permitted mobile station 25 will be described in detail below, before the link can be less cost-consuming.

在示例性实施例中,许多条单独F-GCH信道被用于在特定时刻提供相应数目的单独准许。 In an exemplary embodiment, a number of pieces of individual F-GCH channels are used to provide a corresponding number of individual grant at a particular time. 各F-GCH信道被码分复用。 Each F-GCH channels are code division multiplexed. 这就便于能以到达特定预期移动台所需的功率水平发射每个准许的能量。 This can facilitate the particular intended to reach a desired transmitting power level of each mobile station permitted energy. 在可选实施例中, 单个的单独准许信道可以被采用,同时许多个单独准许被时间复用。 In an alternative embodiment, a single individual grant channel may be employed, while a plurality of time multiplexed individual grant. 为了改变时间复用的单独F-GCH上的每个准许的功率,可能会引入额外的复杂度。 In order to change the power of each grant on a time multiplexed individual F-GCH used, may introduce additional complexity. 在本发明的范围内可以采用任意的信令技术用于传送公共的或单独的准许。 Within the scope of the present invention may employ any of the signaling techniques for communicating common or individual grant.

在一些实施例中,考虑到同一时刻的相对较大数目的单独准许,采用相对较大数目的单独准许信道(即,F-GCH)。 In some embodiments, considering the relatively large number of individual grant the same time, the use of a relatively large number of individual grant channels (i.e., F-GCH). 在这种情况下,可能会希望能限制每个移动台必须监视的单独准许信道的数目。 In this case the number, it may be desirable to limit each individual mobile station must monitor the grant channel. 在一个示例性实施例中,定义了单独准许信道的总数目的各种子集。 In one exemplary embodiment, a single object defines various subsets of the total number of grant channels. 每个移动台被分配给单独准许信道的一个子集来监视。 Each mobile station is assigned a subset of individual grant channels to monitor. 这使得移动台能减小处理的复杂 This enables the mobile station can reduce the complexity of the process

度并相应的减少了功率消耗。 2 and accordingly reduces power consumption. 由于调度基站可能不能够随意分配单独准许的集合(例如不能够对单组中的成员作出所有的单独准许,因为通过设计那些成员不监视一条或多条单独准许信道),所以要权衡调度的灵活性。 Since the scheduling base station may not be able to arbitrarily assign individual grant set (e.g. not able to make all of the individual permit single member of a group, because they do not monitor one or more by designing those members of the individual grant channels), so to weigh the flexible scheduling of sex. 注意的是这种灵活性的降低并不一定会造成容量的损失。 Note that this flexibility does not necessarily reduce the loss of capacity. 为了说明, 考虑包括四个单独准许信道的实例。 To illustrate, consider the grant channel comprises four separate instances. 偶数编号的移动台可以被分配来监视前两个准许信道,而奇数编号的可以被分配来监视后两个准许信道。 The even numbered mobile stations may be assigned to monitor the front two grant channels, and the odd numbered two may be assigned to monitor the grant channel. 在另一个实例中,子集可以重叠,使得偶数的移动台监视前三个准许信道,而奇数的移动台监视后三个准许信道。 In another example, the subsets may overlap, such that the even before the mobile station monitors three grant channels, and the odd mobile station monitors three grant channels. 很清楚调度基站不能随意地分配来自任意一个组(偶数的或奇数的〉中的四个移动台。这些实例仅仅是说明性的。在本发明的范围内可以采用带有任意子集配置的任何数目的信道。 Clearly scheduling base station can not arbitrarily assign four mobile stations> from any of a group (even or odd. These examples are merely illustrative. Within the scope of the present invention with any subset of any configuration may be employed number of channels.

已经作出请求的但没有接收到单独准许的其余的移动台,可以被允许在使用公共准许的R-ESCH上发送,该公共准许指定了每个其余的移动台必须坚持的最大T/P比率。 But has not received the requesting mobile station to the remaining individual grant, it may be allowed to transmit on the R-ESCH using a common grant, which specifies each of the remaining common grant mobile stations must adhere to the maximum T / P ratio. 公共F-GCH也被称为前向公共准许信道(F-CGCH)。 Common F-GCH may also be referred to as forward common grant channel (F-CGCH). 移动台监视一条或多条单独准许信道(或其子集)以及公共F-GCH。 Mobile station monitors the one or more individual grant channels (or a subset thereof), and a common F-GCH. 除非被给予单独准许,否则在公共准许被发布时移动台才可以发射。 Unless permission is given alone, or the mobile station may transmit only when the public is allowed to publish. 公共准许指示了其余的移动台(公共准许移动台)可以以一定类型的QoS发射数据的最大T/P比率。 Common grant indicates the remaining mobile stations (the common grant mobile stations) may transmit a maximum T / P ratio data of a certain type of QoS.

在示例性实施例中,每个公共准许在许多子分组发射间隔内是有效地。 In an exemplary embodiment, each common grant in a number of sub-packet emission interval is effective. 一旦接收公共准许,已经发送请求但没有得到单独准许的移动台可以开始在后续发射间隔内发射一个或多个编码器分组。 Upon receiving a common grant, a transmission request but it has not permitted the individual mobile station can begin transmitting the one or more encoder packets within the subsequent transmission intervals. 准许信息可以被重复多次。 Grant information may be repeated multiple times. 这就允许能以比起单独准许来说减小的功率水平发送公共准许。 This allows the common grant to be able to send than a single permit for reduced power level. 每个移动台可以组合来自多个发射的能量以可靠地解码公共准许。 Each mobile station may combine the energy from multiple transmit in order to reliably decode the common grant. 因此,可以为低几何性的移动台选择公共准许,例如,在就前向链路容量方面单独准许被认为太浪费的情况下。 Thus, a common grant may be selected for the low geometry mobile station, for example, before it is considered a waste permit the case to the individual link capacity. 然而,公共准许仍需要开销, 以下详细描述了用于减少这种开销的各种技术。 However, the public still need to grant overhead, the following detailed description of the various techniques for reducing this overhead.

F-GCH被基站发送到该基站为新的R-ESCH分组的发射调度的每个移动台。 F-GCH is transmitted to the base station for each mobile station transmits the scheduling base station a new R-ESCH packet. 它还可以在编码器分组的发射和重传期间被发送,以促使移动台在拥塞控制变成必要时,修改编码器分组的后续子分组的发射的T/P 比率。 When it can be transmitted during transmission encoder packet and the retransmission, the mobile station to cause congestion control becomes necessary, modify the subsequent sub-packet transmission encoder packet of the T / P ratio.

在示例性实施例中,公共准许包括12个比特,这12个比特包括3 比特类型字段用于指定下面九个比特的格式。 In an exemplary embodiment, the common grant consists of 12 bits, 12 bits which includes 3-bit type field to specify the format of the following nine bits. 剩余的比特为如在类型字段中指定的那样的三个等级的移动台指示最大允许的T/P比率,其中用3 比特表示每个等级的最大可允许的T/P比率。 The remaining bits indicate the maximum allowed T / P ratio is as specified in the type field of the mobile station such as three levels, wherein each level represents the maximum allowable T / P ratio of 3 bits. 移动台等级可以是基于QoS 请求的,或是基于其他标准的。 The mobile station may be based on the QoS level request, or based on other criteria. 其他各种公共准许格式可以被预想到, 并且对于本领域的普通技术人员来说将会很明显。 Various other common grant formats can be envisioned, and will be apparent to those of ordinary skill in the art.

在示例性实施例中,单独准许包括12个比特,这12比特包括:11 比特用于为正被准许发射的移动台指定移动ID和最大允许T/P比率,或者用于明确地用信号通知移动台改变其最大允许T/P比率,包括将最大允许T/P比率设成0 (即,告知移动台不用发射R-ESCH)。 In an exemplary embodiment, individual grant comprises 12 bits, 12 bits which include: 11 bits for specifying a mobile ID and maximum allowed T / P ratio is being transmitted permitted mobile station, or to explicitly signal the the mobile station to change its maximum allowed T / P ratio, including the maximum allowed T / P ratio is set to 0 (i.e., telling the mobile station not transmit R-ESCH). 这些比特为特定移动台指定了移动ID (192个值中的一个)和最大允许T/P (10个值中的一个)。 These bits specify the Mobile ID (a 192 values) and the maximum allowed T / P (a 10 values) for the specific mobile station. 在可选实施例中,1个长准许比特可以为特定的移动台被设定。 In an alternative embodiment, a permission of the bits may be set to a specific mobile station. 当长准许比特被设置成1时,移动台被准许允许在ARQ信道上发射相对较大的固定的、预定数目(该数目能够用信令更新)个分组。 When the permission bit is set to 1 when the mobile station is allowed to transmit a relatively large permitted, in a fixed predetermined number of ARQ channels (this number can be updated with signaling) packets. 如果长准许比特被设置成零,则移动台被准许发射一个分组。 If the permission bit is set to zero, the mobile station is granted to transmit one packet. 移动台可以被告知用零T/P比率规定来断开它的R-ESCH发射,并且如果长准许比特是关(off)状态或者如果在更长的时间段内长准许比特是开(on),则这可以被用于信号通知移动台断开它为了单个分组的单个子分组发射的在R-ESCH上的发射。 The mobile station may be informed by the zero T / P ratio predetermined to disconnect its R-ESCH emission, and if the permission bit is off (off) state or if the permission is a bit longer period of time in the open (on) , then this can be notified to the mobile station a signal transmitted disconnect it on the R-ESCH for a single subpacket individual packets transmitted.

在一个示例性实施例中,移动台只监视源自服务基站的F-GCH。 In one exemplary embodiment, the mobile station only monitors the F-GCH from the serving base station. 如果移动台接收到F-GCH消息,那么移动台遵循F-GCH消息中的速率信息并忽略速率控制比特。 If the mobile station receives F-GCH message, then the mobile station follows the rate information in the F-GCH message and ignores the rate control bits. 一种可选方案是移动台可使用以下原则,该原则为:如果来自不是服务基站的基站的任意速率控制指示符指示速率减小(即,RATE—DECREASE命令,将在以下做详细说明),那么即使F-GCH 指示增加速率移动台也将减小其速率。 An alternative embodiment is the mobile station can use the following principles, the principle: If any rate from the base station than the service base station control indicator indicates a reduced rate (i.e., RATE-DECREASE command, will be described in detail below), even if the F-GCH indicates an increase rate of the mobile station will decrease its rate.

在可选实施例中,移动台可以监视来自所有基站或来自移动台的活动集中的基站的子集的F-GCH。 In an alternative embodiment, the mobile station can monitor the base stations or from a subset of all active mobile stations from the centralized base station F-GCH. 高层信令通过越区切换指示消息或其他消息向移动台指示监视哪条F-GCH以及如何以信道分配组合它们。 Layer signaling or other handover indication message indicating handover messages to the mobile station monitors which of the F-GCH channel allocation and how to combine them. 注意的是,来自不同基站的F-GCH的子集可以被迸行软组合。 Note that a subset of F-GCH from different base stations may be soft-combined into line. 移动台会被通知到这种可能性。 The mobile station will be notified of this possibility. 在对来自不同基站的F-GCH进行了可能的软组合之后,在任意一个时刻仍可能存在多条F-GCH。 After the F-GCH from different base stations may be made of soft combining, there may still be multiple F-GCH at any one time. 然后移动台可以把其发射速率确定为最低的准许速率(或其他某种规则)。 The mobile station can determine its transmission rate as the lowest granted rate (or some other rule).

R-PICH R-PICH

反向导频信道(R-PICH)被从移动台发射到活动集中的基站。 Reverse pilot channel (R-PICH) is transmitted to the base station from the active set of the mobile station. 为了在反向链路功率控制中使用,可以在一个或多个基站处测量R-PICH中的功率。 For use in reverse link power control, the R-PICH may be measured at the power of one or more base stations. 如本领域内已知的那样,导频信号可以被用于提供幅度和相位测量,以用于相干解调中。 As is known in the art, pilot signals may be used to provide amplitude and phase measurements for use in coherent demodulation. 如上所述,移动台可用的发射功率的数量(无论是受调度基站限制还是受移动台的功率放大器的内在限制的限制)在导频信道、单条业务信道或多条业务信道、和多条控制信道当中进行分摊。 As described above, the number of mobile stations available transmit power (whether the scheduled Node B limits or internal restrictions by the power amplifier of the mobile station). In the pilot channel, a single traffic channel or a plurality of traffic channels, and a plurality of control apportioned among the channels. 对于较高数据速率和调制格式,可能需要附加的导频功率。 For higher data rates and modulation formats may require additional pilot power. 为了简化用于功率控制的R-PICH的使用和避免与所需导频功率的瞬时改变有关的其中一些问题,附加信道可以被分配来用作补充或辅助信道。 To simplify the use of R-PICH for power control, and to avoid instantaneous changes required pilot power, wherein some of the problems related to the additional channel may be allocated for use as a supplemental or secondary channel. 尽管, 通常,如在此公开的那样,导频信号通过使用数据序列被发送,承载信号的信息还可以被用来在生成解调的参考信息时使用。 Although, in general, as disclosed herein, a pilot signal is transmitted by using the data sequence, the information bearing signal may also be used to generate the reference information used when demodulated. 在示例性实施例中,R-RICH被用来传送附加导频功率需求。 In an exemplary embodiment, R-RICH is used to carry the additional pilot power requirements.

R-RICH R-RICH

反向速率指示符信道(R-RICH)被移动台用来指示反向业务信道, Reverse rate indicator channel (R-RICH) is used by the mobile station indicating reverse traffic channel,

28R-ESCH上的发射格式。 Transmission format on the 28R-ESCH. 此信道移动台也可以被替代地称为反向分组数据控制信道(R-PDCCH)。 This channel of the mobile station may alternatively be referred to as a reverse packet data control channel (R-PDCCH).

每当移动台在发射子分组时,R-RICH就可以被发射。 Whenever the mobile station transmitted sub-packet, R-RICH may be transmitted. 当移动台在R-ESCH上是空闲时,R-RICH也可以带着零速率指示被发射。 When the mobile station is idle on R-ESCH, R-RICH may also be transmitted with zero-rate indication. 零速率R-RICH帧的发射(指示R-ESCH没有正被发射的R-RICH)帮助移动台检测到移动台是空闲的,为移动台维持反向链路功率控制,和其他功能。 Transmitting (indicating R-ESCH is not being transmitted R-RICH) zero-rate R-RICH frames help the mobile station detects that the mobile station is idle, maintain reverse link power control for the mobile station, and other functions.

R-RICH帧的开始时间是对准当前R-ESCH发射的开始时间的时刻。 Start time of R-RICH frame is time aligned with the start of the current R-ESCH transmission timing. R-RICH的帧持续时间可以与相应R-ESCH发射的帧持续时间相同,或比相应R-ESCH发射的帧持续时间短。 Short frame duration of R-RICH frame duration may be transmitted to the corresponding R-ESCH same or emission than the corresponding R-ESCH frame duration. R-RICH输送并传送R-ESCH发射的发射格式,诸如有效负荷、子分组ID和ARQ实例序列编号(AI一SN) 比特和用于差错检测的CRC。 R-RICH transmission format and transmits conveyance R-ESCH transmission, such as payload, subpacket ID and ARQ instance SEQ ID NO (AI a SN) bits and CRC for error detection. 示例性AI一SN是每次在特定ARQ上发射新分组时都翻转(flip)的比特,又是被称为"色比特"("colorbit")。 Exemplary AI SN is at a flip (Flip) emitted each time a new packet on a particular ARQ bits, and is known as "color bit" ( "colorbit"). 这可以被用于异步ARQ,在异步ARQ中在分组的子分组发射之间没有固定定时。 This may be used for asynchronous ARQ, there is no fixed timing between the asynchronous packet transmitted ARQ sub-packet. 色比特可以用于防止接收器把同一个ARQ信道上的一个分组的子分组与相邻分组的子分组组合在一起。 Color bit may be used to prevent the receiver from a sub-packet of the same packet and adjacent to one ARQ packet channel subpackets together. R-RICH还可以运送附加信息。 R-RICH may also transport the additional information.

R-ESCH R-ESCH

在此处所述的示例性实施例中,增强型反向补充信道(R-ESCH)被用作反向链路业务数据信道。 In the exemplary embodiment described herein, the Enhanced Reverse Supplemental Channel (R-ESCH) is used as the reverse link traffic data channel. 为R-ESCH可以釆用任意数目个发射速率和调制格式。 For the R-ESCH may preclude the use of any number of transmission rate and modulation format. 在示例性实施例中,R-ESCH具有以下特性:支持物理层重传。 In an exemplary embodiment, R-ESCH has the following properties: Physical layer retransmissions support. 对于第一码为1/4速率码(Rate 1/4 code)时的重传,重传使用1/4 速率码并且能量组合被使用。 For the first retransmission when the code rate 1/4 code (Rate 1/4 code) for the retransmission 1/4 rate code and energy combining is used. 对于第一码为速率比1/4大的码时的重传, 增量冗余被利用。 For the first retransmission when larger code than the 1/4 code rate, incremental redundancy is utilized. 基础代码是1/5速率码。 Code rate 1/5 base code. 可选的,还可以为所有情况使用增量冗余。 Optionally, you can also use incremental redundancy in all cases.

为自主和调度用户支持混合自动重复请求(HARQ),这两种用户都可以接入R-ESCH。 Autonomous and scheduled users to support hybrid automatic repeat request (HARQ), both users can access the R-ESCH.

可以用重传之间的固定定时支持多个ARQ信道同步操作:同一个分组的连续子分组之间可以允许固定数目个子分组。 Timing can support multiple ARQ channels with a fixed synchronization between retransmissions: a fixed number of sub-packets can allow between consecutive sub-packets of same packet. 也允许交错发射。 Also it allows interleaving emission. 作为实例,对于5ms的帧,能够用子分组之间的3个子分组延迟支持4信道ARQ。 As an example, for 5ms frames, it is possible delay between subpackets with 3 subpacket supports 4 channel ARQ.

表1列出了增强型反向补充信道的示例性数据速率。 Table 1 lists example data rates of the reverse enhanced supplemental channel. 5ms的子分组大小被描述,并且伴随的信道已被设计成适应这种选择。 5ms subpacket size is described, and the accompanying channels have been designed to accommodate such selection. 对于本领域的技术人员很明显的是也可以选择其他子分组大小。 Those skilled in the art it is obvious that sub-packet can also choose other sizes. 并不为这些信道调节 Not adjusted for these channels

导频参考水平,g卩,基站具有把给定操作点作为目标来选择T/P的灵活性。 The pilot reference level, g Jie, the base station has the flexibility to select a given operating point T / P as a target. 这个最大T/P值被在前向准许信道上进行信号通知。 This maximum T / P value is signaled to the first grant channel. 当超出发射功率时移动台可以选择较低的T/P,以让HARQ满足需要的QoS。 When the transmission power exceeds the mobile station can choose a lower T / P, to allow HARQ meet the required QoS. 层3信令消息也可以通过R-ESCH发射,允许系统不用R-FCH和/或R-DCCH 操作。 Layer 3 signaling messages may also be emitted through the R-ESCH, allowing the system without R-FCH and / or R-DCCH operation.

在示例性实施例中,turbo编码被用于所有速率。 In an exemplary embodiment, turbo coding is used for all rates. 对R=l/4编码, 使用与当前的cdma2000反向链路类似的交织器(interleaver)。 For R = l / 4 coding, using a similar current cdma2000 reverse link interleaver (interleaver). 对RI/5的编码,使用与cdma2000前向分组数据信道类似的交织器。 Similar to interleaver before coding RI / 5, and using the cdma2000 packet data channel.

据采用此处的原则,任意数目的速率、格式、子分组重复内容、子分组持续时间等等的组合对本领域的技术人员来说都会很明显。 According to the principles employed here, any number of rates, formats, subpacket repetition content, composition of subpacket duration, etc. will be apparent to those skilled in the art. 可替换的 Replaceable

F-CPCCH F-CPCCH

当不存在F-FCH和F-DCCH时或者当存在F-FCH和F-DCCH但这两种信道不是对用户专用的时,前向公共功率控制信道(F-CPCCH)可以用于对各种反向链路信道进行功率控制。 When there is no F-FCH and F-DCCH or F-FCH, when present, and F-DCCH but the two channels are not dedicated to a user, a forward common power control channel (F-CPCCH) may be used for various The reverse link power control channel. 在信道分配方面,移动台被分配到反向链路功率控制信道。 In the channel allocation, the mobile station is assigned to a reverse link power control channel. F-CPCCH可以包含许多个功率控制子信道。 F-CPCCH may contain a number of power control subchannels.

F-CPCCH可传送称为公共拥塞控制子信道(F-OLCH)的功率控制子信道。 F-CPCCH may be referred to as a common transmit power congestion control subchannel (F-OLCH) control subchannel. 尽管能够使用其他速率,示例性拥塞控制子信道典型地速率为100bps。 While it is possible to use other rates, exemplary congestion control subchannel is typically rate is 100bps. 在此称为忙碌比特的单个比特(为了可靠性其可以被重复)向处于自主发射模式、或是处于公共准许模式、或者处于这两种模式中的移动台指示是增加还是减小它们的速率。 Referred to herein as a single bit busy bit (which may be repeated for reliability) to transmit in autonomous mode, or in the common grant mode, or in the mobile station indicates that two modes is increasing or decreasing their rates . 在可选实施例中,单独准许模式也可以对该比特有反应。 In an alternative embodiment, individual grant modes may be responsive to the bits. 可以以响应F-OLCH的发射类型的任意组合采用各种实施例。 Emission type may be any combination of the F-OLCH response to various embodiments. 这能够以随机的方式或是确定的方式进行。 This can be done in a random manner or a deterministic manner.

在一个实施例中,把忙碌比特设置成'0'表示响应该忙碌比特的移动台应该减小它们的发射速率。 In one embodiment, the busy bit is set to '0' in response to the mobile station busy bit should decrease their transmission rate. 将忙碌比特设置成表示发射速率的相应增加。 The busy bit set to indicate a corresponding increase in transmission rate. 无数种其他信令方案可以被采用,这对于本领域的技术人员将会很明显,并且以下会详细说明各种可选实例。 Myriad other signaling schemes may be employed, it will be apparent to those skilled in the art, and the following will explain in detail the various alternative examples.

在信道分配期间,移动台被分配到这些特定的功率控制信道。 During channel assignment, the mobile station is assigned to these special power control channels. 功率控制信道可以控制系统中的所有移动台,或者可替换地,移动台的变化的子集可由一个或多个功率控制信道所控制。 Power control channel may control all mobile stations in the system, or alternatively, varying subsets of the mobile stations by one or more power control channels controlled. 注意的是,对这种用于拥塞控制的特定信道的利用仅仅是一个实例。 Note that use of this particular channel for congestion control is merely one example.

F-ACKCH F-ACKCH

前向确认信道,或是F-ACKCH可以由基站用来确认R-ESCH的正确接收,并且还能够用于扩展现存的准许。 Forward Acknowledgment Channel, or F-ACKCH may be used by the base station acknowledges the correct receipt of the R-ESCH, and can also be extended for existing grant. F-ACKCH上的确认(ACK) 指示子分组的正确接收。 Acknowledgment (ACK) on the F-ACKCH indicates correct reception of a subpacket. 由移动台对那个子分组的附加发射是不必要的。 Additional emitted by the mobile station for that subpacket is unnecessary. F-ACKCH上的否定性确认(NAK)允许移动台发射另一个子分组,这受每个分组的子分组的最大允许数目所限制。 Negative acknowledgment (NAK) on the F-ACKCH allows the mobile station transmits another sub-packet, by which the maximum allowable number of sub-packets per packet is limited.

在此处详细说明的实施例中,F-ACKCH被用于提供对接收子分组的肯定或否定的确认,以及是否将发布速率控制命令的指示(将在以下关于F-RCCH信道进行描述)。 In the embodiments herein detailed in, F-ACKCH is used to provide confirmation of the received subpacket positive or negative, and whether a rate control command to issue instructions (to be on F-RCCH channel will be described).

图5是说明3个值的F-ACKCH的示例性实施例。 FIG 5 is an exemplary embodiment of the F-ACKCH three values. 此示例性F-ACKCH 包括单个指示符,该指示符被从一个或多个基站发射到移动台,用于指示来自移动台的R-ESCH上的发射是否已经被各自的基站正确接收到。 This example F-ACKCH comprises a single indicator that is transmitted from one or more base stations to the mobile station, for indicating on the R-ESCH transmitting from the mobile station has already been correctly received by a respective base. 在示例性实施例中,F-ACKCH指示符被活动集中的每个基站发射。 In an exemplary embodiment, each base station F-ACKCH indicator is set active transmitter. 可替换地,F-ACKCH可以被活动集的指定子集发射。 Alternatively, F-ACKCH may be set to transmit the specified sub-active set. 发送F-ACKCH的基站的集合可以被称为F-ACKCH活动集。 Sending the F-ACKCH may be referred to as a set of base stations F-ACKCH Active Set. F-ACKCH活动集可以由层3 (L3 ) 信令通过信号通知给移动台,并且可以在信道分配期间、在切换指示消息(HDM)中、或通过本领域内已知的其他技术被指定。 F-ACKCH Active Set may be formed of layer (L3) signaling 3 signaled to the mobile station, and may during channel assignment, in a Handoff Direction Message (a HDM), or in designated by other techniques known in the art.

例如,F-ACKCH可以是具有以下值的3种状态的信道:NAK, ACK一RC和ACK—STOP。 For example, F-ACKCH may be a 3-state channel with the following values: NAK, ACK and a RC ACK-STOP. NAK指示来自移动台的分组不得不被重传(然而,如果最后的子分组已经被发送,则移动台可能需要使用任何的可用技术,诸如请求/准许、速率控制或是自主发射来重新发送分组)。 NAK indicates that the packet from the mobile station has to be retransmitted (however, if the last subpacket has been sent, the mobile station may need to use any available technique, such as request / grant, rate control, or autonomous transmission packet to re-transmit ). 如果NAK对应于分组的最后一个子分组,则移动台可能需要监视对应的F-RCCH上的速率控制指示符(以下将进一步详细说明)。 If the NAK corresponds to last subpacket of a packet, the mobile station may need to monitor the rate of the corresponding F-RCCH indicator control (described in further detail below).

ACK—RC指示不再需要重传来自移动台的分组,并且移动台应该监视对应F-RCCH上的速率控制指示符。 ACK-RC indicating no need for a retransmission packet from the mobile station and the mobile station should monitor the rate corresponding to the F-RCCH indicator control. ACK—STOP也指示不在需要重传。 ACK-STOP also indicates not need to be retransmitted. 但是,在这种情况下,移动台应该为下一次发射回到自主模式,除非移动台在F-GCH上接收到准许消息(如以上详细说明的那样)。 However, in this case, the mobile station should transmit back to the next autonomous mode (As described in detail above) unless the mobile station receives a grant on F-GCH message.

L3信令可以指示移动台是否要软组合来自其活动集中的不同基站的F-ACKCH指示符。 L3 signaling may indicate whether the mobile station is to soft-combining F-ACKCH indicators from different base stations in its active set. 这可能与依照IS-2000的修订本C操纵功率控制比特等效。 This may be equivalent to the control bits in accordance with IS-2000 Revision C of the actuating power is present. 例如,可能存在根据信道分配发送的指示符比方说ACK—COMB—IND或是处于切换消息中的指示符,其会指示移动台是否要组合来自不同基站的F-ACKCH指示符。 For example, there may be for example a channel assignment indicator according to said transmitted ACK-COMB-IND message in handoff or an indicator, which indicates whether the mobile station will be combined F-ACKCH indicators from different base stations. 可以采用各种技术来发射F-ACKCH,以下将给出其实例。 Various techniques may be employed to transmit F-ACKCH, examples of which will be given below. 一些实例包括分离的TDM信道、 TDM/CDM信道或一些其他格式。 Some examples include a separate TDM channel, TDM / CDM channel, or some other format.

在此实例中,根据分组是否被确认,存在两类根据监视F-ACK信道获得的结果。 In this example, according to whether the packet was confirmed, the presence of the monitoring results obtained by the two types of F-ACK channels. 如果NAK被接收到,则可有多种选项。 If NAK is received, you can have several options. 移动台可以发送附加的子分组直到巳经发送完最大数目的子分组。 The mobile station may send additional subpackets until the maximum number has already started sending the sub-packets. (在示例性实施例中,使用相同的发射格式发送子分组,无论该子分组是通过自主发射还是准许发射启动的,以及无论该分组是否属于速率控制修订版。在可选实施例中可以通过使用此处公幵的任意技术来改变子分组发射格式)。 (In an exemplary embodiment, the same transmission sub-packet transmission format, regardless of whether the sub-packet is emitted by the autonomous transmission, or allowed to start, and regardless of whether the packet belongs to a rate control revision. In an alternative embodiment by using any technique well-Jian here to change the subpacket transmission format). 在最后一个子分组的NAK之后,移动台或者可以采取与对应的速率控制命令相关的行动(监视F-RCCH),根据以前的准许或速率控制命令停止发射(即, 如果需要的话恢复到自主发射),或者可以响应新接收到的准许。 After the last subpacket NAK, the mobile station or may take the corresponding rate control command related actions (monitoring F-RCCH), a control command according to the previous grant or rate stops transmitting (i.e., if desired, be restored to independent emission ), or it may respond to a new received grant.

如果ACK被接收到,其可能对应于速率控制命令或是对应停止的指示。 If the ACK is received, which may correspond to a rate control command or an indication to stop corresponds. 如果指示速率控制,则速率控制信道(F-RCCH)被监视和跟随。 If the indicated rate control, the rate control channel (F-RCCH) is monitored and followed. 如果结果是要停止,那么移动台不跟随F-RCCH上的速率控制指示符并恢复到自主模式(以最多为分配的最大自主速率发射)。 If the outcome is to stop, then the mobile station does not follow the rate control on the F-RCCH indicator and revert to autonomous mode (up to the maximum autonomous rate allocated emission). 如果在接收到ACK一STOP的同时接收到显式准许(explicit grant),那么移动台遵从显式准许中的命令。 If an explicit grant is received (explicit grant) while receiving an ACK STOP, then the mobile station to comply with the explicit grant commands.

例如,首先考虑单个活动集成员或是来自全部扇区的指示符是相同的情况(并且因此由ACK—COMB—IND来指示)。 For example, first consider a single Active Set member or indicators from all sectors are the same situation (and therefore indicated by the ACK-COMB-IND). 在这种情况下存在单个合成指示符。 There is a single synthetic indicator in this case. 当移动台接收到NAK时(指示符不被发送),那么移动台(在适当时刻)重传下一个子分组。 When the mobile station receives a NAK (indicator not transmitted), then the mobile station (at the appropriate time) the next sub-packet retransmission. 如果移动台没有接收到最后一个子分组的ACK,那么移动台继续进行下一个分组(错误分组可以根据正在遵从的重传算法被重传)。 If the mobile station does not receive an ACK last subpacket, then the mobile station proceeds a packet (packet error may be retransmitted according to the retransmission algorithm is being complied with). 然而,移动台将其当作速率控制指示(即, 监视速率控制信道)。 However, as the mobile station to the rate control indication (i.e. monitors the rate control channel).

在此实例中,基本原则为如下这样(适用于单个活动集成员和多个不同的F-ACKCH活动集成员)。 In this example, the basic principle in the following manner (for single Active Set member and a plurality of different F-ACKCH Active Set members). 如果任意指示符是ACK一STOP或是ACK—RC,则结果是ACK 。 If any indicator is an ACK STOP or ACK-RC, the result is an ACK. 如果没有指示符是ACK—STOP或是ACK_RC, If no indicator is ACK-STOP or ACK_RC,

33则结果是NAK。 33 is a result NAK. 那么,关于速率控制,如果任意指示符是ACK一STOP, 则移动台将停止(即,恢复到自主模式,或者若有准许的话则响应准许)。 Then, on the rate control, if any indicator is an ACK the STOP, the mobile station will stop (i.e. revert to autonomous mode, or if the response is permitted if permitted). 如果没有指示符是ACK一STOP并且至少一个指示符是ACK_RC,则解码相应基站的速率控制信道(F-RCCH)上的指示符。 If no indicator is an ACK STOP and at least one indicator is ACK_RC, decode the indicator channel rate corresponding base station on the (F-RCCH). 如果最后一个子分组已经被发射并且所有指示符是NAK的话,则解码所有基站的速率控制信道(F-RCCH)上的指示符。 If the last subpacket has been transmitted, and all indicators are NAK, then decoding rate control channels of all base stations on the indicator (F-RCCH). 以下将联系对F-RCCH的描述进一步详细说明这些情景中响应速率控制命令。 The following description will contact the F-RCCH in further detail these scenarios response rate control command.

ACK一RC命令,其与速率控制信道相组合,可以被当作一类称为ACK且继续命令的命令。 A command ACK RC, which is combined with the rate control channel, may be used as a class of commands referred to as ACK and continue commands. 移动台可以继续依照各种可以被发布的速率控制命令,来继续发射后续的分组(以下详细说明各实例)。 The mobile station may continue in accordance with the various rate control commands may be issued to continue to transmit the subsequent packet (described in detail below for each example). ACK且继续命令允许基站确认对分组的成功接收,同时,允许移动台通过使用能导致成功接收分组的准许(服从根据速率控制命令可能得到的修订本〉来发射。这就节省了新准许的开销。 Continue command allows the base station and the ACK acknowledge successful reception of the packet, while allowing the mobile station by using the successfully received packet can result grant (subject to revision control commands may obtained according to the rate> transmitted. This saves the overhead of a new grant .

在图5中说明的F-ACKCH的实施例中,ACK_STOP符号的肯定值、 NAK的NULL符号、和ACK一RC符号的否定值被使用。 Example F-ACKCH is illustrated in FIG. 5, the negative value of positives ACK_STOP symbol, a NULL symbol NAK and ACK RC symbol a is used. F-ACKCH上的开关键控(即,不发送NAK)给予了基站(尤其是非调度基站) 一种在发送ACK的代价(所需功率)太高时则不发送ACK的选择权。 Off keying on F-ACKCH (i.e., not sending NAK) to give the base stations (especially non-scheduling base stations) A consideration transmitting an ACK (required power) is not too high the option ACK transmission. 这就提供给基站一种在前向链路容量和反向链路容量之间的折衷选择,因为正确接受到的没有被ACK确认过的分组将可能在稍后的时刻触发重传。 This provides a base station for a trade-off between the forward link capacity and reverse link capacity, because the correct acknowledgment is not received over the ACK packet will likely trigger a retransmission at a later time.

在本发明的范围内可以采用多种发送F-ACKCH的技术。 Within the scope of the present invention may be transmitted using a variety of techniques F-ACKCH. 每个移动台的单独信号可以被组合到公共信道内。 Separate signal for each mobile station may be combined into a common channel. 例如,多个移动台的确认响应可以被进行时间复用。 For example, acknowledgment may be a plurality of mobile stations are time-multiplexed. 在示例性实施例中,在一条F-ACKCH上最多能够支持96个移动台ID。 In an exemplary embodiment, it can support up to 96 mobile station ID on one F-ACKCH. 可以利用附加的F-ACKCH来支持附加的移动台ID。 Additional may be utilized to support additional F-ACKCH mobile station ID.

另一个实例是将多个移动台的多个确认信号映射到正交函数集合上。 Another example is to map a plurality of acknowledgment signals to the plurality of mobile stations orthogonal function set. Hadamard编码器是用于映射到正交函数集合的编码器的一个实例。 Hadamard Encoder is one example of an encoder for mapping to a set of orthogonal functions. 其它各种技术也可以采用。 Various other techniques may also be employed. 例如,沃尔什码(Walshcode)和其它类似的纠错码可用来编码这些信息比特。 For example, Walsh code (Walshcode) and other similar error correcting code may be used to encode the information bits. 如果独立的每条子信道具有独立的信道增益,则可以以不同的功率水平发射到不同用户。 If independent each subchannel has an independent channel gain, may be transmitted to different users at different power levels. 示例性F-ACKCH 为每个用户传送一个专用的三值的标记。 An exemplary F-ACKCH transmission for each user a dedicated three-valued flag. 每个用户监视来自其活动集中的所有基站的F-ACKCH (或者,可选的,信令可以定义减小的活动集以减少复杂度)。 Each user monitors the F-ACKCH from all base stations in its Active Set (or, alternatively, signaling may define a reduced active set to reduce complexity).

在各实施例中,两条信道的每条都由128码片的沃尔什覆盖序列(Walsh cover s叫uence)进行覆盖。 In various embodiments, the 128-chip Walsh by each of the two channels covering sequence (Walsh cover s call uence) covered. 一条信道在I信道上发射,而另一条在Q信道上发射。 A channel I transmitted on a channel, and the other transmitted Q channel. F-ACKCH的另一个实施例使用单个128码片的沃尔什覆盖序列来同时支持最多为192个的移动台。 Another Walsh Example F-ACKCH uses a single 128-chip cover sequence to support up to 192 mobile stations. 示例性实施例为每个三值标记使用10ms的持续时间。 An exemplary embodiment for each of the three embodiments the use value of the flag duration of 10ms.

回顾一下,当移动台有需要使用R-ESCH发送的分组时,其可以在R-REQCH上请求。 Recall that when the mobile station has need to use the R-ESCH packet transmission, it may request on the R-REQCH. 基站可以通过使用F-GCH用准许来响应。 The base station may respond with by using the F-GCH grant. 但是,这种操作可能会有些花费太高。 However, this operation may be a little too expensive. 为了减少前向链路开销,F-ACKCH可以发送ACK一RC标记,该标记通过调度基站(或者是当支持来自多个基站的软切换准许时的其它设备)以较低的代价扩展了现存的准许(服从速率控制)。 In order to reduce the front, F-ACKCH may send the ACK RC flag to a link cost, the marking by scheduling base station (or other devices when soft handover is supported when permission from multiple base stations) to lower the cost of the existing expanded grant (subject to rate control). 这种方法被用于单独准许和公共准许。 This method is used to separate and the common grant permission. ACK^RC根据准许基站(或基站)被使用,并且扩展了对相同的ARQ信道(服从速率控制)上的一个或多个编码器分组的当前准许。 The ACK ^ RC permits a base station (or base station) is used, and extends the current grant for the same ARQ channel (subject to rate control) one or more encoder packet.

注意的是,如图4所示,并不是活动集中的每个基站都被要求向回发送F-ACKCH的。 Note that, as shown in FIG. 4, not every base station in the active set are required to send back the F-ACKCH. 正在软切换中发送F-ACKCH的基站的集合可以是活动集的子集。 The base station transmitting the F-ACKCH in soft handoff are set may be a subset of the active set. 在2003年6月30日提交的题为"Code Division Multiplexing Commands On a Code Division Multiplexed Channel "("码分复用信道上的码分复用命令")的共同待审的美国专利申请号10/611,333 中公开了用于发射F-ACKCH的示例性技术,该专利被转让给本发明的受让人。 In 2003, entitled, filed June 30 "Code Division Multiplexing Commands On a Code Division Multiplexed Channel" ( "code division multiplexing code division multiplexing command channel") co-pending US Patent Application No. 10 / 611,333 discloses an exemplary technique for transmitting the F-ACKCH, which patent is assigned to the assignee of the present invention.

F-RCCH F-RCCH

前向速率控制信道(F-RCCH)被从一个或多个基站发射到移动台, 以信号通知下一次发射的速率调整。 Before the rate control channel (F-RCCH) is transmitted from one or more base stations to the mobile station to transmit a signaling rate in the adjustment. 移动台可以被指配来监视来自F-ACKCH活动集的或是来自F-ACKCH活动集的子集的每个成员的指示符。 The mobile station may be assigned to monitor the indicator from every member, or F-ACKCH Active Set is a subset of the F-ACKCH from the active set. 为了清楚起见,发送由移动台监视的F-RCCH的基站的集合被称为F-RCCH活动集。 For clarity, the set of F-RCCH transmitted by the mobile station monitors the base station is referred to as F-RCCH Active Set. F-RCCH活动集可以由层3 (L3)信令进行信号通知, 层3信令可以在信道分配期间,在切换指示消息(HDM)中指定,或者通过任意的本领域技术人员已知的其它各种方式来指定。 F-RCCH Active Set may be performed by layer (L3) signaling 3 signaling, Layer 3 signaling during channel assignment may, in a handover indication message (a HDM) is specified, present or by any other known to those of skill a variety of ways to specify.

图6说明了示例性F-RCCH。 FIG 6 illustrates an exemplary F-RCCH. 该F-RCCH是具有以下值的3种状态信道:RATE—HOLD,指示移动台能够以仅仅与当前分组的速率相同的速率发射下一个分组;RATE一INCREASE,指示移动台能够确定地或是随机地相对于当前分组的发射速率增加发射下一个分组的最大速率;和RATE—DECREASE,指示移动台能够确定地或是随机地相对于当前分组的发射速率减小发射下一个分组的最大速率。 The F-RCCH is having the value of three states channel: RATE-HOLD, indicating the mobile station can transmit the next packet to only the rate of the current packet at the same rate; the RATE an INCREASE, indicating the mobile station can determine to or random increasing the relative emission maximum rate at which a packet transmission rate for a current packet; and rATE-dECREASE, indicating the mobile station can be determined randomly or with respect to the maximum transmission rate of the rate of the current packet transmitting one packet is reduced.

L3信令可以指示移动台是否要组合来自不同基站的速率控制指示符。 L3 signaling may indicate whether the mobile station from different base stations to be combined rate control indicator. 这与利用IS-2000修订版C中的功率控制比特所做出的相似。 This bit made using similar to IS-2000 Revision C power control. 这样, 将存在基于信道分配发送的并且位于切换消息中的指示符,例如RATE一COMB一IND,其将指示移动台是否要软组合来自不同基站的F-RCCH比特。 Thus, there will be based on the channel allocation message transmitted switch and an indicator located, for example, a RATE COMB IND one, which would indicate whether the mobile station is to soft-combining F-RCCH bits from different base stations. 本领域技术人员将认识到,存在许多用于发射诸如F-RCCH,包括分离的TDM信道、组合的TDM/CDM信道的信道的格式, 或其它格式。 Format skilled in the art will recognize that there are many TDM / CDM channels for transmitting such as F-RCCH, including separate TDM channels, combined channels, or other formats.

在各实施例中,可以存在各种速率控制配置。 In various embodiments, various rate control configurations may exist. 例如,所有移动台可以由每个扇区的单一指示符来控制。 For example, all mobile stations may be controlled by a single indicator per sector. 可替换地,每个移动台可由专用于每个移动台的每扇区的独立的指示符所控制。 Alternatively, each mobile station may be dedicated to each mobile station separate indicator per sector controlled. 或者,移动台的组可以由它们自身分配的指示符来控制。 Alternatively, the group of mobile stations may be controlled by their own assigned indicator. 这样的配置使得具有相同的最大QoS等级的移动台被分配相同的指示符。 Such a configuration so as to have the same maximum QoS class of the mobile station is assigned the same indicator. 例如,唯一的流被指定为"尽力服务" 的所有移动台可以由一个分配的指示符控制,这样就容许减少用于这些尽力服务的流的负荷。 For example, only stream is designated "best effort" to all mobile stations may be assigned by a control indicator, thus allowing to reduce the load for these best effort streams.

此外,信令可以用于配置移动台,使得移动台只注意来自服务基站或来自F-RCCH活动集中的所有基站的F-RCCH指示符。 In addition, signaling may be used to configure a mobile station so that the mobile station only from the serving base station or from a note that F-RCCH indicator F-RCCH all active set base stations. 要注意的是, 如果移动台只监视来自服务基站的指示符并且RATE_COMB—IND指定来自多个基站的指示符是相同的,那么移动台可以在做出决定前组合与服务基站相同的组中的所有指示符。 It is noted that, if the mobile station is only monitoring the indicator from the serving base station and RATE_COMB-IND specific indicator from multiple base stations are the same, then the mobile station may be combined with a base station serving the same group before making a decision All indicator. 在任意时刻具有使用的不同的速率控制指示符的基站的集合会被称为F-RCCH当前集合。 Set at any time with the use of different rate control indicator of the base station will be referred to the current set of F-RCCH. 这样,如果移动台被配置成使得移动台仅仅注意来自服务基站的F-RCCH指示符,那么F-RCCH当前集合的大小为1。 Thus, if the mobile station is configured such that only the mobile station Note F-RCCH indicator from the serving base station, then the size of the F-RCCH is a current collection.

可以预想到,F-RCCH的使用规则可以由基站来调节。 It is envisioned, F-RCCH usage rule may be adjusted by the base station. 以下是对于具有单个成员的F-RCCH当前集合的移动台的规则的示例性集合。 The following rules for the F-RCCH mobile station having a single member of the current collection of exemplary set. 如果RATE—HOLD被接收到,移动台不改变其速率。 If a RATE-HOLD is received, the mobile station does not change its rate. 如果接收到RATE—INCREASE,则移动台将其速率增加一(即, 一个速率水平、以上在表l中详细说明的实例)。 If the received RATE-INCREASE, a mobile station increases its rate (i.e. one rate level, more detailed in Table l in the example). 如果接收到RATE—DECREASE,则移动台把其速率减少一。 If the received RATE-DECREASE, the mobile station to which a reduced rate. 注意的是,移动台仅仅在环境指示时才监视这些指示符(即,作为ACK处理结果的行为,以下将进一步详细说明的,其指示速率控制是激活的)。 Note that, the mobile station monitors these indicators only when just environment indicator (i.e., ACK behavior as a result of the processing, described in further detail below, indicating rate control is active).

以下是对于具有多个F-RCCH当前集合成员的移动台的规则的示例性集合。 The following are the rules for a mobile station having a plurality of current collection member F-RCCH exemplary set. 把速率增加/减小1个速率的简单规则被修改。 The rate of increase / decrease rate of a simple rule is modified. 如果接收到任何ACK一STOP,则移动台恢复到自主速率。 If no ACK is received a STOP, the mobile station returns to autonomous rates. 否则,如果任何指示符是RATE—DECREASE,移动台把其速率减小一次。 Otherwise, if any indicator is a RATE-DECREASE, the mobile station decreases its rate once. 如果没有指示符是RATE—DECREASE,并且至少一个基站具有指示RATE_HOLD的速率控制(作为ACK处理的结果)的行为,那么移动台维持相同的速率。 If no indicator is a RATE-DECREASE, and at least one base station with an indication RATE_HOLD rate control (as a result of the ACK process) behavior, then the mobile station maintains the same rate. 如果没有指示符是RATE—DECREASE ,没有基站指示速率控制和RATE_HOLD ,并且至少一个基站具有速率控制的行为和RATE—INCREASE的指示;那么移动台把其速率加一。 If no indicator is a RATE-DECREASE, no base station indicates rate control and RATE_HOLD, and at least one base station with an indication of RATE-INCREASE behavior and rate control; then the mobile station to its rate plus one.

示例性组合准许、ARO和速率控制命令的实施例 Exemplary embodiments allow combination, ARO, and rate control commands

为了概括一些以上介绍的实施方案,移动台可以被授权进行自主发射,这尽管可能在吞吐量上受到限制,但便于具有低时延。 To summarize some of the embodiments described above, the mobile station may be authorized to transmit autonomously, although it may be limited in throughput, low latency but facilitates. 在这样的情况下,移动台可以发射而无需对最大R-ESCH的T/P比率(即T/PMaxauto) In this case, the mobile station may transmit without a T / P ratio of the maximum R-ESCH (i.e. T / PMaxauto)

的请求,该T/PM^,to可以由基站通过信令来设置和调节。 Request, the T / PM ^, to be set and adjusted by the base station through signaling.

可以在一个或多个调度基站处确定调度,并且可以通过在F-GCH上以相对较高的速率发射的准许来分配反向链路容量。 Scheduling may be determined at one or more scheduling base station, and may allocate the reverse link capacity by permitting the F-GCH at a relatively high rate of transmission. 此外,速率控制命令可被用于以较低的开销修改以前准许的发射或自主发射,这样就调整了对反向链路容量的分配。 In addition, the rate control command may be used to modify the emission with low overhead previous grant or autonomous emission, thus adjusting the allocation of reverse link capacity. 因此调度可被用于紧密地控制反向链路负荷, 并且这样就保护了语音质量(R-FCH)、 DV反馈(R-CQICH)和DV确认(R-ACKCH)。 The scheduler can be used to tightly control the reverse link load and thus protect voice quality (R-FCH), DV feedback (R-CQICH) and DV acknowledgment (R-ACKCH).

单独准许使得能对移动台的发射进行详细控制。 It enables individual permit detailed control of the transmitting mobile station. 可以基于几何性和QoS选择移动台,以使吞吐量最大化同时又维持所需的服务水平。 QoS can be based on the geometry and choose the mobile station, in order to maximize throughput while maintaining required service levels. 公共准许便于高效的通知,尤其是对于低几何性的移动台来说。 Public permitted facilitate efficient notification, especially for low geometry mobile station it is.

与F-RCCH信道组合起来的F-ACKCH信道有效地实现"ACK且继续"命令,其以较低的代价扩展了现存准许。 In combination with the F-RCCH channel up F-ACKCH channel effectively implement "ACK and continue" command, which is a low cost extended existing grant. (如上所述,该继续过程可以被速率控制,并且在以下被进一步详细说明)。 (As described above, the process may be continued controlled rate, and is described in further detail below). 这些原则对单独准许和公共准许都有效。 These principles are valid for individual and public grant permission. 在2003年8月21日提交的题为"Scheduled and Autonomous Transmission and Acknowledgement"("被调度的禾口自主发射和确认")的同时待审的美国专利申请号10/646,955中公开了用于在诸如lxEV-DV反向链路的共享资源上调度、准许、和发射的各种实施例和技术,其中该专利被转让给本发明的受让人,并且在此引入该专利作为参考。 While "Scheduled and Autonomous Transmission and Acknowledgement" ( "the scheduled launch of Hekou and independent confirmation"), entitled August 21, 2003 filed pending US Patent Application No. 10 / 646,955 discloses for Examples and various techniques such as lxEV-DV scheduling shared resources on the reverse link, grant, and transmission embodiment in which the patent is assigned to the assignee of the present invention, and which patent is incorporated herein by reference.

图7说明了示例性方法700, 一个或多个基站可以利用该方法响应来自一个或多个移动台的请求和发射来分配容量。 FIG 7 illustrates an exemplary method 700, one or more base stations may utilize the method and the response to a request from one or more transmitting mobile stations allocated capacity. 注意的是,所示的方框顺序仅仅是一个实例,并且各方框的顺序可以被互换并且可以与其它未示出的方框组合起来,这些都不会脱离本发明的范围。 Note that the order of blocks shown is merely one example, and the order of the various blocks may be interchanged and may be combined with other blocks, not shown, which are not departing from the scope of the invention. 该处理在方框710 处开始。 The process begins at block 710. 基站接收任何可能是由一个或多个移动台发射的发射请求。 Any base station receives the transmission request may be transmitted by one or more mobile stations. 由于方法700可以被循环不定次,所以可能会有可能还没被准许过的在先请求也被接收到,这些请求可以与新请求组合起来以根据请求估计发射的需求数量。 Since the method 700 may be variable cycle times it may not be possible it had been previously granted request is also received, these requests may be combined with new requests it needs to transmit the request of the estimated quantity.

在方框720中, 一个或多个移动台可以发射各子分组,这些子分组被基站接收到。 In block 720, one or more mobile stations may transmit the sub-packets are sub-packets received by the base station. 这些被发射的子分组可以是根据以前的准许发射的(可能会由以前的速率控制命令修改过)或是自主地发射的(也可能由以前的速率控制命令修改过)。 These sub-packets are transmitted may be transmitted according to the previous permission (which may be controlled by the previous rate command modified) or autonomously transmitted (control commands may also be modified from the previous rate). 自主发射的数目、被注册的移动台的数目、和/或其它因素可以被用于估计对自主发射的需求数量。 The number of autonomous transmission, the number of registered mobile stations, and / or other factors may be used to estimate the amount of demand for autonomous transmission.

在方框730中,基站解码任何接收到的子分组,可选地与各自以前接收到的子分组软组合起来,以确定分组是否被无误地接受到。 In block 730, the base station decodes any received sub packets, optionally in combination with a respective previously received subpackets soft combined to determine whether the packet is received without error. 这些确定将被用于向各自的发射移动台发送肯定的或是否定的确认。 These will be used to determine definitely transmitted to respective transmit a negative acknowledgment or the mobile station. 回想到, HARQ可以被用于R-ESCH上的分组发射。 Recall, HARQ packet can be used to transmit on the R-ESCH. 也就是,分组可以被最多发射一定数目次直到它被至少一个基站正确接收到。 That is, the packet may be transmitted up to certain number of directory until it is correctly received at least one base station. 在每个帧边界处,每个基站解码R-RICH帧并确定R-ESCH上的发射格式。 In each frame boundary, each base station decodes R-RICH frame and determines the transmit format on the R-ESCH. 基站还可以通过使用当前的R-RICH帧和以前的R-RICH帧来做出这个决定。 The base station may also be used to make this decision by using the current R-RICH frame and previous R-RICH frames. 可选的, 基站还可以通过利用从反向次要导频信道(R-SPICH)和/或R-ESCH提取的其它信息来做出决定。 Alternatively, the base station can be from, and / or other information extracted from R-ESCH reverse secondary pilot channel (R-SPICH) use to make decisions. 利用该决定出的发射格式,基站试着通过使用以前接收到的子分组在适当时候解码R-ESCH上的分组。 The use of the decided transmission format, by using the base station tried packets previously received subpackets at the appropriate time to decode the R-ESCH.

在方框740中,基站执行调度。 In block 740, the base station performs scheduling. 可以采用任意的调度技术。 Any scheduling techniques may be employed. 为了执行调度从而分配共享资源(在此实例中为反向链路容量),基站可以根据请求、预期的自主发射、对当前信道调节的估计、和/或其它各种参数来给发射需求乘以一个系数。 In order to perform scheduling so as to distribute the shared resource (in this example the reverse link capacity), the base station may request, transmitting autonomous expected, estimates of current channel adjustment, and / or various other parameters to be multiplied by the emission requirements a factor. 调度可以为各个移动台采取各种形式。 Scheduling may take various forms for the various mobile stations. 各实例包括做出准许(根据请求分配、增加以前的准许或是减小以前的准许), 生成用于增加、减小或维持以前的准许速率或自主发射的速率控制命令, 或者忽视请求(将移动台转换成自主发射)。 Examples include making each grant (allocating according to a request, increasing a previous grant or reducing a previous grant), generating a increase, decrease, or maintain the rate of the previous grant or autonomous transmission rate control commands, or ignoring a request (the converted into an autonomous mobile station transmit).

在步骤750中,基站为每个移动台处理接收到的发射。 In step 750, the base station transmitting the received process for each mobile station. 这可以包括, 除了其它功能以外,确认接收到的子分组,并有条件地生成响应发射请求的准许。 This may include, among other functions, acknowledging receipt of subpackets, and conditionally generating a grant in response to a request to transmit. 图8说明了生成准许、确认和速率控制命令的示例性方法750。 8 illustrates generation grant, acknowledgment, and an exemplary method 750 of rate control command. 其适合用于图7中说明的示例性方法700中,并且可以改造成利用其它方法使用,这对本领域的普通技术人员来说将会很明显。 An exemplary method which is suitable for 700 illustrated in FIG. 7, and may be engineered to use with other methods, it will be apparent to one of ordinary skill in the art. 如上所述,在每次经过方法700期间,方法750可以为每个活动的移动台进行循环。 As described above, each pass during the method 700, the method 750 may cycle to each active mobile station.

在判断框805中,如果当前正被处理的移动台的子分组还没有被接收到,则前进至方框810。 In decision block 805, if the sub-packets for the mobile station currently being processed has not been received, the process proceeds to block 810. 不需要有确认,并且不会发布速率控制命令。 There is no need to confirm, and does not publish the rate control command. F-ACKCH和F-RCCH都不需要被发射,并且这两个符号都可以被DTX (不发射)。 F-ACKCH and F-RCCH need not be transmitted, and both symbols may be the DTX (no emission). 在判断框815中,如果已经接收到请求,则前进至判断框820。 In decision block 815, if the request has been received, the process proceeds to decision block 820. 否则该处理可以停止。 Otherwise, the process can be stopped.

在判断框820,如果在调度期间已经为这个移动台确定准许,则前进至方框825来在适当的F-GCH上发射准许。 In decision block 820, if a grant has been determined for this mobile station during scheduling, proceed to block 825 to transmit the grant on the appropriate F-GCH. 然后该处理可以停止。 Then, the process can be stopped. 移动台可以在下一个适当的帧期间依照这个准许发射(以下将参考图10—12 详细说明定时实例)。 The mobile station may next frame period in accordance with the appropriate permitted transmission (hereinafter described in detail with reference to FIGS. 10-12 timing instances).

返回到判断框805,如果来自移动台的子分组被接收到,则前进至判断框830。 Returning to decision block 805, if the sub-packet from the mobile station is received, the process proceeds to decision block 830. (注意的是,可能是子分组和请求被接收到,在这种情况下可以为移动台执行出自判断框805的两条分支,为了清楚起见未显示细节)。 (Note that it may be sub-packet and the request is received, in which case the two arms can be performed by decision block 805 for a mobile station, details not shown for clarity).

在判断框830中,如果接收到的子分组被正确解码,则将生成ACK。 In decision block 830, if the received subpacket was decoded correctly, the ACK will be generated. 前进至判断框835。 Proceeds to decision block 835. 如果期望有速率控制(包括速率保持,即"继续"), 则前进至方框845。 If rate control is desired (including a rate hold, i.e. "Continue"), proceed to block 845. 如果不期望有速率控制,则前进至方框840。 If no rate control is desired, proceed to block 840. 在方框840中,在F-ACKCH上发射ACK-STOP。 In block 840, the transmit ACK-STOP on F-ACKCH. F-RCCH不需要被发射,即, 可能产生了DTX。 F-RCCH need not be transmitted, i.e., may have a DTX. 如果此时没有生成准许,移动台将被转移到自主发射(或者必须停止,如果自主发射不可能或者不被采用的话)。 If permission is not generated at this time, the mobile station will be transferred to autonomous transmission (or must stop, if autonomous emission possible or not used). 可替代地, 可以不顾停止命令而发布新准许。 Alternatively, you can ignore the stop command and issued new permits. 如上所述,前进至判断框820以处理这个决定。 As described above, proceeds to decision block 820 to process this decision. 在方框845中,速率控制被指示。 In block 845, rate control was indicated. 同样的,将在F-ACKCH上发射ACK_RC。 Similarly, ACK_RC will transmit on F-ACKCH. 前进至判断框850。 Proceeds to decision block 850. 如果希望增加,则在F-RCCH上发射RATEJNCREASE。 If you want to increase, the transmitter RATEJNCREASE on F-RCCH. 然后该处理可以停止。 Then, the process can be stopped. 如果不希望增加,则前进至判断框860。 If you do not want to increase, then proceeds to decision block 860. 在判断框860中,如果希望减小,则在F-RCCH上发射RATE—DECREASE。 In decision block 860, if desired to reduce, the emission RATE-DECREASE on the F-RCCH. 然后该处理可停止。 Then the process may stop. 否则,在F-RCCH上发射RATE一HOLD。 Otherwise, transmit a RATE HOLD on the F-RCCH. 在此实例中,由DTX指示保持状态。 In this example, indicated by a DTX state remains. 然后该处理可停止。 Then the process may stop.

返回到判断框830,如果接受到的子分组没被正确解码,则将生成NAK。 Returning to decision block 830, if the received subpacket was not decoded correctly, NAK will be generated. 前进至方框875以在F-ACKCH上发射NAK。 Proceeds to block 875 to transmit on F-ACKCH NAK. 在此实例中,NAK 由DTX指示。 In this example, NAK is indicated by a DTX. 前进至判断框880以判断接收到的子分组是否是最后一个子分组(即,已经达到子分组重传的最大数目)。 Proceeds to decision block 880 to determine whether a received subpacket is the last subpacket (i.e. the maximum number of subpacket retransmissions has been reached). 如果不是,在此实例中, 移动台可以根据以前的发射格式重传。 If not, in this example, the mobile station may retransmit according to the previous transmission format. DTX可以在F-RCCH上发射,如方框895中指示的一样。 DTX may be transmitted on F-RCCH, as indicated in block 895 of the same. (在这种情况下可选实施例可以执行可选的信令, 其实例将在以下被描述。)然后该处理可停止。 (In this case, alternative embodiments may perform alternative signaling, examples of which will be described below.) Then the process may stop.

如果接受到的并且被响应NAK的子分组是最后一个子分组,则从判断框880前进至判断框885以确定是否希望进行速率控制(包括保持)。 If the response is received and is the last subpacket NAK to a subpacket, proceeds from decision block 880 to decision block 885 to determine if the desired rate control (including retention). 这是用低幵销扩展以前的准许或自主发射(若有的话,包括以前的速率控制)的示例性技术。 This is a low pin extended Jian previous grant or autonomous transmission (if any, including previous rate control) of the exemplary technique. 如果不期望进行速率控制,则为F-RCCH生成DTX。 If no rate control is desired, for the F-RCCH generation DTX. 在此实例中,移动台将发射下一个子分组。 In this example, the mobile station will transmit the next subpacket. 与判断框835相类似,如果没有为移动台生成新的准许,则该移动台将被转移到自主发射(如果可能的话)。 And decision block 835 is similar, if a new grant is not generated for the mobile station, the mobile station will be transferred to autonomous transmission (if possible). 可替换地,可以生成新的准许,其将为移动台指示可用的发射。 Alternatively, a new grant may be generated, the mobile station will transmit an indication of its available. 如上所述,前进至判断框820以执行这种判断。 As described above, proceeds to decision block 820 to perform this determination.

在判断框885中,如果期望进行速率控制,则前进至判断框850。 In decision block 885, if rate control is desired, proceed to decision block 850. 如上所述,可以为F-RCCH上的发射生成增加、减小、或保持。 As described above, can be increased to emit generated on F-RCCH, reduced, or maintained. 然后该处理可停止。 Then the process may stop.

概括而言,如果分组被正确接收到,则基站可以发送肯定确认并可以有条件地向移动台发送速率控制消息。 In summary, if a packet is received correctly, the base station may send positive acknowledgment and conditionally control message to the mobile station transmission rate.

基站可以(在F-ACKCH上)发送ACK—STOP以用信号通知分组已经被传递并且移动台为下一次发射恢复到自主模式。 The base station may (on F-ACKCH) to transmit ACK-STOP has signaled packet is transmitted and the mobile station to recover for the next transmit autonomous mode. 如果需要的话,基站还可以发送新的准许。 If desired, the base station may also send a new grant. 为了下一次发射,移动台可以最多以准许的速率发射。 In order to transmit next, the mobile station may transmit up to the granted rate. 在任意一种情况下,F-RCCH上发射DrX。 In either case, the transmit DrX F-RCCH. 在一个实施例中, 只有服务(或准许)基站可以生成准许。 In one embodiment, only a serving (or grant) the base station may generate a grant. 在可选实施例中,一个或多个种选项的细节将在以下详细说明)。 In an alternative embodiment, The details of one or more kinds of options will be described in detail below).

基站可以(在F-ACKCH上)发送ACK—RC和(在F-RCCH上)发送RATE_HOLD,以用信号通知分组被传递并且移动台可发送下一个分组的最大速率与当前分组的发送速率相同。 The base station may (on F-ACKCH) transmits ACK-RC and the transmission (on F-RCCH) RATE_HOLD, to be transmitted to signal packet and the mobile station may transmit a packet of the maximum rate and transmission rate of the current packet is the same.

基站可以(在F-ACKCH上)发送ACK—RC和(在F-RCCH上)发送RATE—INCREASE,以用信号通知分组被传送并且移动台可以相对当前分组的发送速率增加下一个分组发射的最大速率。 Maximum base station may (on F-ACKCH) transmits ACK-RC and the transmission (on F-RCCH) RATE-INCREASE, it is transmitted in a packet is signaled and the mobile station can be relative to the current transmission rate of packets increasing the packet transmission rate. 移动台可以遵循基站和移动台都知道的某些规则来增加速率。 The mobile station may follow certain rules base station and mobile station to know the rate of increase. 该增加可以是确定的或是随机的。 This increase may be determined or random. 本领域的技术人员将认识到无数种用于增加速率的规则。 Those skilled in the art will recognize myriad rules for increasing the rate.

基站可以(在F-ACKCH上)发送ACK—RC和(在F-RCCH上)发送RATE—DECREASE,以用信号通知分组被传送并且移动台应该相对当前分组的发送速率减小下一个子分组发射的最大速率。 The base station may (on F-ACKCH) and transmits ACK-RC transmission (on F-RCCH) RATE-DECREASE, it is transmitted to signal the mobile station and the packet transmission rate of the current packet should be relatively reduced emission next subpacket the maximum rate. 移动台可以遵循基站和移动台都知道的某些规则来减小速率。 The mobile station may follow certain rules base and mobile stations are aware of the reduced rate. 该减小可以是确定的或是随机的。 The reduction may be random or determined. 本领域的技术人员将认识到无数种用于减小速率的规则。 Those skilled in the art will recognize myriad rules for decreasing a rate.

如果分组没有成功地被基站接收到,并且分组可以被进一步重传(即,不是最后一个子分组),则基站在F-ACKCH上发送NAK。 If the packet is not successfully received by the base station, and the packet may be further retransmitted (i.e., not the last subpacket), the base station sends a NAK on F-ACKCH. 注意的是在此实例中F-RCCH上发送DTX。 Note that the DTX transmission on the F-RCCH in this example.

如果不能对分组进行进一步重传(即,最后一个子分组),则以下是基站可以采取的可能的行动。 If the group can not be further retransmitted (ie, last subpacket), the following are possible actions the base station may take. 基站可以同时发送NAK (在F-ACKCH上) 和在F-GCH上的准许消息,以用信号通知移动台分组没被传送并且移动台可以为下一次发射最大以准许速率发射。 The base station can send NAK (on F-ACKCH) and a grant message on the F-GCH to inform the mobile station using the packet signal is not transmitted and the mobile station may transmit the next to permit a maximum rate transmission. 在这种情况下F-RCCH上发射DTX。 In this case, F-RCCH emission DTX. 在一个实施例中,只有服务(或准许)基站可以生成准许。 In one embodiment, only a serving (or grant) the base station may generate a grant. 在可选实施例中, 一个或多个基站可以生成准许(处理这种选择的细节将在以下详细说明)。 In an alternative embodiment, the one or more base stations may generate a grant (details of this selection process is described in detail below).

基站也可以(在F-ACKCH上)发送NAK和(在F-RCCH上)发送RATE—HOLD,以用信号通知分组没被传递并且移动台可发送下一个分 The base station may (on F-ACKCH) and sends a NAK (on F-RCCH) transmits RATE-HOLD, not to signal the packet is transmitted and the mobile station may transmit the next sub-

组的最大速率与当前分组的发送速率相同。 Maximum rate set with the same transmission rate of the current packet.

基站也可以(在F-ACKCH上)发送NAK和(在F-RCCH上)发送RATE—INCREASE,以用信号通知分组没被传送并且移动台可以相对当前分组的发送速率增加下一个子分组发射的最大速率。 The base station may transmit (on F-ACKCH) NAK and (on F-RCCH) transmits RATE-INCREASE, to signal that the packet has not been transmitted and the mobile station may be relatively lower to increase the current packet transmission rate a subpacket transmitted The maximum rate. 移动台可以遵循基站和移动台都知道的某些规则来增加速率。 The mobile station may follow certain rules base station and mobile station to know the rate of increase. 该增加可以是确定的或是基站也可以(在F-ACKCH上)发送NAK和(在F-RCCH上)发送RATE—DECREASE,以用信号通知分组没被传送并且移动台应该相对当前分组的发送速率减小下一个子分组发射的最大速率。 This increase may be a base station or may be determined (on F-ACKCH) and a transmission sends a NAK (on F-RCCH) RATE-DECREASE, not being transmitted to the packet and to signal the mobile station relative to the current packet should be transmitted a sub-packet is reduced at a rate of maximum rate transmission. 移动台可以遵循基站和移动台都知道的某些规则来减小速率。 The mobile station may follow certain rules base and mobile stations are aware of the reduced rate. 该减小可以是确定的或是随机的。 The reduction may be random or determined.

在可选实施例中(图8中未显示其细节),可以生成NAK且停止的代替品。 In an alternative embodiment (details not shown in FIG. 8), generates a NAK and stop may substitute. 例如,在以上情景中,不能把对应NAK的F-RCCH上的DTX 与"NAK且保持"区别开来。 For example, in the above scenario, a DTX not the corresponding F-RCCH and the NAK "NAK and hold" distinguished. 如果希望有一条用于强制停止(或者用于转换到自主发射)的命令,基站也可以在最后一个子分组之前使用NAK 和速率控制来指示,关于最后一个子分组的速率保持(或是增加、或是减小)是要表示停止。 If there is a wish for forcibly stopping (for conversion to customize or emission) of the command, the base station may also use NAK and rate control is indicated prior to the last subpacket, subpacket rate on a final holding (or increase, or decreasing) is intended to mean stop. 例如,在这种特殊情况下,任意一种速率控制命令(即,RATEJNCREASE, RATE—DECREASE,或RATE—HOLD)可以被指配来表示停止。 For example, in this particular case, any of a rate control command (i.e., RATEJNCREASE, RATE-DECREASE, or RATE-HOLD) may be assigned to indicate stop. 移动台将知道最后一个子分组何时被发送,因此能够随后解析速率控制命令。 The mobile station will know when the last subpacket was transmitted, then it is possible to parse the rate control commands. 当基站知道:如果在NAK出现的情况下紧随最后的子分组发射之后是停止,则选定的速率控制命令可以与前一个子分组的NAK—起被发布。 When the base station knows: if immediately after the last subpacket NAK occurs in the case of emission is stopped, the selected rate control command may be a previous sub-packet is issued from NAK-. 接收到与(不是最后一个)子分组的NAK 在一起的被标识的速率控制命令的移动台将知道,关于最后的子分组的NAK (和RATE—HOLD,例如)将意味着任何以前的准许会被废除,并且移动台必须恢复到自主发射。 And a NAK is received (not the last) sub-packet with a rate control command is identified mobile station will know, NAK (and RATE-HOLD, for example) on the final subpacket would mean that any previous grant would It was abolished, and the mobile station must revert to autonomous transmission. 但仍旧可能会有与最后的子分组NAK — 起发送的但不用于此目的的速率控制命令(即,RATEJNCREASE或RATE—DECREASE)。 But still may be the last subpacket NAK - but not used for this purpose since the rate control command is transmitted (i.e., RATEJNCREASE or RATE-DECREASE). 可选方案是发送具有零(或者降低的)速率的准许连同最后的NAK,尽管这将需要附加的开销。 Alternative is transmitted with a zero (or lowered) rate along with the final grant NAK, although this would require additional overhead. 本领域的技术人员将很容易根据"NAK且停止"的可能性与其它可能性权衡这些可选方案。 Those skilled in the art will readily according to the possibility of "NAK and stop" with other possibilities tradeoff these alternatives. 然后可以基于各种事件的可能性优化所需开销。 Then based on the likelihood of various events required to optimize costs.

图9说明了移动台用于监视和响应准许、确认和速率控制命令的示例性方法卯0。 FIG 9 illustrates a mobile station to monitor and respond to grant, acknowledgment and rate control method for an exemplary command d 0. 这种方法适合在一个或多个移动台中采用,如上所述,这些移动台用于与方法700中采用的一个或多个基站联合使用,以及与其它基站实施例联合使用。 This method is suitable for one or more mobile stations in use, as described above, one or more base stations and mobile stations for use in the method 700 used in combination, and in combination with other embodiment of the base station embodiments. 该处理开始于方框910。 The process begins at block 910. 移动台监视F-GCH、 F-ACKCH和F-RCCH。 The mobile station monitors the F-GCH, F-ACKCH and F-RCCH. 注意的是,在不同实施例中,如上所述,移动台可以监视这些信道中的一条或多条。 Note that, in various embodiments, as described above, the mobile station may monitor one or more of these channels. 例如,可能存在多条准许信道,而且每个移动台可以监视它们当中的一条或多条。 For example, there may be multiple grant channels, and each mobile station may monitor one or more of them. 还要注意到的是,这些信道中的每条可以从一个基站接收到,或者在移动台处于软切换时可以从多于一个的基站接收到。 Also note that each of these channels may be received from a base station, or when the mobile station is in soft handoff may be received from the base station to more than one. 信道可以合并指向多个移动台的消息或命令,这样移动台可以提取专门指向它的消息或命令。 The combined channel may be directed to a plurality of mobile stations or command message, the mobile station may extract such special messages or commands directed to it.

也可以采用其它原则来允许移动台有条件地监视其中一条或多条控 Other principles may also be employed to allow a mobile station to conditionally monitor one or more control wherein

制信道。 System channel. 例如,如上所述,当ACKJSTOP被发布时,F-RCCH可以不被发射。 For example, as described above, when ACKJSTOP is released, F-RCCH may not be transmitted. 注意,在这种情况下,当ACK_STOP被接收到时,移动台无需监视F-RCCH。 Note that, in this case, when the ACK_STOP is received, the mobile station need not monitor the F-RCCH. 可以规定一条规则,即只有在移动台已经发送过准许消息和/或速率控制命令可以被响应的请求时,移动台才寻找准许消息和/或速率控制命令。 When a predetermined rule may be that only a grant message has been transmitted through and / or rate control command may be in response to a request at the mobile station, the mobile station shall find grant messages and / or rate control command.

在图9的以下描述中,假定移动台以前已经发送子分组,而预期有对于该子分组的确认(包括潜在准许或速率控制命令)响应。 In the following description of FIG. 9, assume that the mobile station has previously transmitted sub-packet, but is expected to confirm that the sub-packet (including potential grant or rate control commands) response. 如果请求以前没有被准许过,则移动台可以仍旧为了响应以前发送的请求的准许而进行监视。 If the request had not been previously granted, the mobile station may still be granted in response to a request sent by the previous monitoring. 本领域的技术人员将会很容易把方法900改造成能够解决这种情形。 Those skilled in the art will readily transformed into the method 900 can solve this situation. 为了讨论清楚起见,这些和其它潜在的移动台处理功能块已被省略。 For clarity of discussion, these and other potential mobile station processing blocks have been omitted.

自判断框915处开始,F-ACKCH的处理开始。 Starts from decision block 915, the process F-ACKCH begins. 移动台提取所有它监视的F-ACKCH信道上的信息。 The mobile station extracts the information it is monitoring all the F-ACKCH channel. 回想到,在移动台和其F-ACKCH活动集的每个成员之间可能存在F-ACKCH。 Recall that there may be the F-ACKCH between the mobile station and every member of its F-ACKCH Active Set. F-ACKCH命令的其中一些可以象通过L3信令规定的那样被软组合。 F-ACKCH commands some of which may be soft-combined, as specified via L3 signaling like. 如果移动台接收到至少一个肯定确认,ACK一RC或是ACK_STOP (在F-ACKCH上),则当前分组已经被正确接收到,并且不需要发射附加的子分组。 If the mobile station receives at least one positive acknowledgment, the ACK an RC or ACK_STOP (on F-ACKCH), the current packet has been received correctly, and additional subpackets need to transmit. 对于下一个分组的发射允许的速率,如果有的话,则需要被确定。 For the next packet transmit rate allowed, if any, need to be determined.

在判断框915中,如果ACI^STOP已经被接收到,则移动台会了解到,以前发射的子分组已经被正确接收到,并且速率控制命令无需被解码。 In decision block 915, if the ACI ^ STOP have been received, the mobile station will be informed that previously transmitted subpacket has been received correctly, and the rate control commands need not be decoded.

在判断框920中,移动台确定是否已经在F-GCH上接收到准许。 In decision block 920, the mobile station determines whether it has received the grant on F-GCH. 如果是的话,则移动台根据准许发射下一个分组,如方框930中指示的那样。 If so, the mobile station transmitting a packet according to the grant, as indicated in block 930. 在一个实施例中,只有一个准许基站做出准许。 In one embodiment, the base station is only permitted to make a grant. 如果从基站接收到ACK一STOP和准许消息,则移动台以等于或低于准许速率的任意速率在相同的ARQ信道上发射新的分组。 If an ACK is received from the base station and a STOP grant message, the mobile station at any rate equal to or lower than the permitted rate of transmitted new packet on the same ARQ channel.

在可选实施例中,多于一个的基站可以发送准许。 In an alternative embodiment, more than one base station may send grant. 如果基站协调该准许,并且发送相同的消息,则移动台可以软组合那些准许。 If the base stations coordinate the grant, and send the same message, the mobile station may soft combine those permitted. 可以采用各种规则来处理不同准许被接收到的情况。 Can employ various rules for different handling of the grant is received. 一个实例是让移动台以接收到的准许中指示的最低速率发射,从而避免在对应于各自的准许基站的小区中的过多干扰(包括无对应准许的ACB^STOP,指示发射应该恢复到自主模式)。 One example is to make the mobile station at the lowest rate indicated in a received grant emission, so as to avoid excessive interference in the cell corresponding to the respective base stations in the grant (including without a corresponding grant ACB ^ STOP, indicating emission should be restored to customize mode). 其它各种可选方案对本领域的技术人员来说也将会很明显。 Various other alternatives will also be obvious to those skilled in the art. 如果在判断框920中没有接收到准许,则移动台必需返回到自主速率,如方框925中所示。 If no grant is received at decision block 920, the mobile station should return to autonomous rate, as shown in block 925. 然后该处理可以停止。 Then, the process can be stopped.

返回到判断框915,如果ACK一STOP没有被接收到,前进至判断框940。 Returning to decision block 915, if an ACK STOP is not received, the process proceeds to decision block 940. 如果ACK一RC被接收到,移动台监视从其接收到肯定确认的基站的对应F-RCCH,如果存在该F-RCCH的话。 If a RC ACK is received, the mobile station monitors received a positive acknowledgment from the base station corresponding to the F-RCCH, if there is, then the F-RCCH. 注意的是,由于F-RCCH 活动集是F-ACKCH活动集的子集,所有在基站和移动台之间可能不存在F-RCCH。 Note that, due to the F-RCCH Active Set is a subset of the F-ACKCH Active Set, all the F-RCCH may not exist between a base station and a mobile station. 还要注意的是,当移动台接受到来自多个基站的F-ACKCH 时,相应消息可能是冲突的。 Also note that, when the mobile station receives F-ACKCH from multiple base stations, the corresponding messages may be in conflict. 例如,可能接收到一个或多个ACK—STOP 命令,可能接收到一个或多个ACK一RC命令,可能接收到一个或多个准许,或是以上情况的任意组合。 For example, one or more may receive ACK-STOP command, may receive an ACK or a plurality of RC command, may receive a grant or more, or any combination of the above. 本领域的技术人员会认识到各种用来实现以适应任意可能情况的规则。 Those skilled in the art will recognize various rules for implementing to accommodate any possible situation. 例如,移动台可以确定最低的可能的发射容许(其可以从没有被准许的ACK^STOP、带有减小的ACK一RC、或带有较低值的准许当中选取)并可以相应地发射。 For example, the mobile station may determine the lowest possible emission permit (which can not be permitted from the ACK ^ STOP, with a decrease of the RC ACK, or with a lower value which permits selection) and transmit correspondingly. 这与己知为"减少模式的或(OR-of-Downs)"规则的技术类似。 This is known as a technology similar to the "reduction mode, or (OR-of-Downs)" rule. 这样的技术可以被用于严格避免与相邻小区的过多干扰。 Such techniques may be used to strictly avoid excessive interference with neighbor cells. 或者, 一个或多个基站可以具有分配给它们的优先权,使得一个或多个基站可以具有胜过其它基站的能力(或许会有附加条件)。 Alternatively, one or more base stations may have a priority assigned to them, such that one or more base stations may have the ability (there may be additional conditions) over other base stations. 例如,调度(或准许)基站可能比软切换中的其它基站更有一部分优先权。 For example, a scheduling (or grant) the base station may be more than a portion of the soft handover in priority to other base stations. 其它规则也可以被预期到。 Other rules can also be expected. (回想到, 一个或多个NAK也可以被接收到,但移动台无需重发。但是,在需要时,移动台可以以类似的方式合并来自正在发NAK的基站的速率控制命令或准许)。 (Recall that one or more of the NAK may also be received, but the mobile station need not retransmit. However, when necessary, the mobile station may send NAK are combined rate from the base station in a similar manner to permit or control commands). 为了简化此处的讨论,当说明移动台确定ACK—STOP、 ACK—RC、 NAK 或是准许是否被接收到时,其可以是把想要的规则集合应用到一些接收到的命令上的结果,或者结果是被标识的命令。 To simplify the discussion herein, when the mobile station determines described ACK-STOP, ACK-RC, NAK, or grant is received whether, which may be desired to set the rules to the results of some of the received command, or the result is the command identified.

如果ACK—RC已经被接收到,则前进至判断框945以开始确定应该遵循哪种类型的速率控制命令。 If the ACK-RC has been received, the process proceeds to decision block 945 to begin determining what type of rate control command should be followed. 如果指示增加,则前进至方框950。 If the indication is increased, the process proceeds to block 950. 下一次发射可以是以自当前速率增加的速率在相同的ARQ信道上发射的。 It may be in the next emission rate from the current rate of increase in the emission of same ARQ channel. 然后,该处理可以停止。 Then, the process can be stopped. 此外,该增加可以是确定的或是随机的。 Furthermore, the increase may be determined or random. 同样, RATE—INCREASE可能不一定导致即时的速率增加,但会在将来增加移动台的发射速率(即,可能在移动台处使用信用式算法(credit-like algorithm)),或者RATE—INCREASE可能导致增加生成的多个速率。 Similarly, RATE-INCREASE may not necessarily result in immediate rate increase but would increase the transmission rate of the mobile station in the future (ie, may use credit-type algorithm at the mobile station (credit-like algorithm)), or may cause RATE-INCREASE increase the rate of generation of the plurality. 在示例性信用算法中,移动台维护内部"平衡/信用"参数。 In an example credit algorithm, a mobile station maintains an internal "balance / credit" parameter. 每当它接收到RATE—INCREASE但不能增加其速率时(因为它耗尽了功率或者耗尽了数据),移动台增加该参数。 When whenever it receives RATE-INCREASE but can not increase its rate (because it ran out of power or data depletion), the mobile station increases the parameter. 当功率或数据变得对移动台可用时,其可以使用在选择数据速率中的存储的"信用/平衡"。 When power or data becomes available for the mobile station, which can be used to select the data rate stored "credit / balance." 各种增加速率的方式对本领域的技术人员来说将会很明显。 A variety of ways to increase the rate will be apparent to those skilled in the art.

如果在判断框945中没有指示增加,则前进至判断框955以确定是否指示减少。 If at decision block 945 does not indicate an increased, the process proceeds to decision block 955 to determine whether to indicate reduced. 如果指示减少,则前进至方框960。 If the indication is reduced, the process proceeds to block 960. 下一次发射可以以自当前速率减小的速率在相同的ARQ信道上发射。 The next transmission may be reduced at the rate from the current rate of transmission on the same ARQ channel. 然后该处理可以停止。 Then, the process can be stopped. 此外,该减小可以是确定的或是随机的。 Furthermore, the reduction may be random or determined. 同样,RATE—INCREASE可能不一定导致即时速率减小但将会在将来减小来自移动台的发射速率(即, 在移动台处使用信用式算法),或者RATE—DECREASE可能导致减小生成的多个速率。 Similarly, RATE-INCREASE may not necessarily result in immediate rate decrease but would decrease the transmission rate from the mobile station in the future (i.e., at the mobile station using the formula credit algorithm), or a RATE-DECREASE may result in a reduction in the generated multi- a rate. 当示例性信用算法被用在RATE—DECREASE的上下文中时,当移动台得到RATE一DECREASE但由于某些原因(例如,有紧急的数据需要被发送)不能遵循该命令时,其得到否定信用,并且在某种意义上该否定信用需要在稍后被偿还。 When the exemplary credit algorithm is used in the RATE-DECREASE context, when a mobile station to obtain a RATE DECREASE but for some reason (e.g. urgent data that needs to be sent) when the command is not follow that a negative credit, and in a sense, the negative credit needs to be repaid later. 减小速率的各种方式对本领域的技术人员来说将会很明显。 Various ways to reduce the rate will be apparent to those skilled in the art.

如果增加和减小都没有被指示,则RATE—HOLD已被接收到。 If increases and decreases have not been indicated, the RATE-HOLD has been received. 如方框965中所示的那样,移动台可以以与当前分组速率相等的最大速率发送下一个分组。 As shown in block 965, such as, the mobile station may transmit at a maximum rate equal to the rate of the current packet a packet. 然后该处理可以停止。 Then, the process can be stopped.

返回到判断框940,如果没有一种ACK已被识别,则NAK将被确定已经被接收到。 Returning to decision block 940, if none of ACK has been identified, the NAK will be determined to have been received. 在判断框970,如果分组仍然可能被重传(即,当前子分组不是最后的子分组),则移动台在相同的ARQ信道上重传该子分组, 同时子分组ID加一,如方框980中说明的那样。 In decision block 970, if the packet may still be retransmitted (i.e., the current sub-packet is not the last subpacket), the mobile station retransmits the subpacket on the same ARQ channel, while the subpacket ID incremented, as indicated by block 980, as described.

在判断框970中,如果当前分组是最后的子分组,则移动台已用光分组的重传。 In decision block 970, if the current packet was the last subpacket, the mobile station has run out of retransmissions of packets. 前进至判断框975以确定是否已经接收到准许(以如上所述的那样与方框920相似的方式)。 Proceeds to decision block 975 to determine whether a grant has been received (block 920 as similar to the manner described above). 如果准许消息被指定给移动台(如上所述,无论是来自单个基站还是来自多于一个的基站),移动台可以以等于或低于准许速率的速率在相同的ARQ信道上发送新分组。 If a grant message is designated to the mobile station (as described above, whether from a single base station or from more than one base station), the mobile station may be equal to or lower than the permitted rate of a new packet transmission rate at the same ARQ channel. 如上所述, 前进至方框930。 As described above, proceeds to block 930.

在判断框975中,如果还没有接收到准许,则移动台可以监视F-RCCH活动集,获得速率控制命令,并决定可在相同的ARQ信道上发送下一个分组时使用的最大速率。 In decision block 975, if a grant has not been received, the mobile station may monitor the F-RCCH Active Set, obtain rate control commands, and decide the maximum rate may be used when a packet transmitted at the same ARQ channel. 当多于一个的速率控制命令被接收到时对速率的选择可以按上述那样做出。 Selection rate may be made as described above, when more than one rate control command is received. 前进至判断框945并按上述那样继续进行。 Proceeds to decision block 945 to proceed as described above and press.

其它各种技术也可以被移动台的示例性实施例所采用。 Various other techniques may also be employed in an exemplary embodiment of a mobile station. 移动台可以监视分组檫除的数目(B卩,在最后的子分组之后没有肯定性确认)。 The mobile station may monitor the number of packets in addition to the Sassafras (B Jie, no positive acknowledgment after the last subpacket). 可以通过计算连续的分组擦除的数目或通过计算窗口内(即,滑动窗口)被擦除的分组的数目来做出测量。 Made may be measured by counting the number of consecutive packets or by erasing window (i.e. a sliding window) the number of erased packets calculated. 如果移动台认识到过多的分组已被擦除, 则可以减小其发射速率,即使速率控制命令指示另一个命令(即, RATE—HOLD或RATE一INCREASE)。 If the mobile station to recognize that excessive packets have been erased, it may reduce its transmit rate even if the rate control commands indicate another command (i.e., RATE-HOLD, or a RATE INCREASE).

在一个实施例中,准许消息可以具有比速率控制比特更高的优先权。 In one embodiment, a grant message may have higher bit rate than the control priority. 可选的,可以用与速率控制比特相同的优先级来对待准许消息。 Alternatively, the rate control may be used with the same priority bits to treat grant message. 在这样的情况下,速率决定可以被修改。 In such a case, rate determination may be modified. 例如,如果没有准许消息被指定给移动台,则使用"减小模式的或"规则或相似的规则根据所有速率控制命令(RATE—INCREASE 、 RATE—HOLD 、 RATE—DECREASE和ACK—STOP)确定下一次发射的速率。 For example, if no grant message is designated to the mobile station, use the "reduction mode or" rule or rules similar to the control command (RATE-INCREASE, RATE-HOLD, RATE-DECREASE, and ACK-STOP) from all the lower rate determining the rate for a single shot. 当准许也被接收到时,下一次发射的速率可以通过使用"减小模式的或"规则或类似的规则根据所有速率控制命令(RATE一INCREASE、 RATE—HOLD、 RATE—DECREASE和ACK—STOP)来确定,其结果将被与准许速率和选择的较小速率相比较。 When the grant is also received, a rate of the next transmission by using the "reduction mode or" rule or the like according to the control rule all rate command (RATE an INCREASE, RATE-HOLD, RATE-DECREASE, and ACK-STOP) determined, the results will be compared with the allowed rate and the smaller rate chosen.

可以采用信令来配置移动台,使得移动台仅仅监视来自服务基站或来自F-RCCH活动集中的所有基站的F-RCCH指示符。 Signaling may be used to configure a mobile station so that the mobile station monitors only from the serving base station or the F-RCCH indicator from the F-RCCH all active set base stations. 例如,当RATE—COMB—IND可能指定来自多个基站的速率控制命令是相同的,移动台可以在做出决定之前组合被标识的组中的所有指示符。 For example, when RATE-COMB-IND may be specified rate control commands from multiple base stations are the same, the mobile station may combine all indicators in the identified group before making a decision. 在任意时刻使用的不同指示符的数目可以被指示为F-RCCH当前集合的大小。 The number of different indicators for use at any time may be indicated as the size of the F-RCCH current collection. 在一个实例中,移动台可以被配置成仅仅监视来自服务基站的那个F-RCCH 指示符,在该情况下F-RCCH当前集合的大小是1 。 In one example, the mobile station may be configured to monitor only the F-RCCH indicator from the serving base station, in which case the magnitude of the current collection is an F-RCCH.

46此外,如上所述,可以采用各种规则来响应F-RCCH上的命令调节速率。 46 Further, as described above, you may respond to commands on the F-RCCH adjustment rate using various rules. 这些规则的任意条可以由来自基站的信令调节。 Article of any of these rules may be adjusted by signaling from the base station. 在一个实例中, 可以存在一个用于确定移动台是否增加或减小其速率以及增加或减小了多少速率的概率和步长的集合。 In one example, there may be a means for determining whether the mobile station increases or decreases its rate, and increases or decreases the probability of the number of steps and rate set. 这些概率和可能的速率步长可以在必要时,通过信令来更新。 These probabilities and possible rate step sizes may, if necessary, updated through signaling.

如上所述,方法卯0可以被改造成包括各种为基站采用的方法750 的可选方案。 As described above, the method d 0 may be modified to include a variety of alternative methods used by the base station 750. 例如,在一个实施例中,由于在F-RCCH上的DTX与NAK 一起指示速率保持,NAK且停止命令没有被明确的定义。 For example, in one embodiment, since the NAK and DTX on F-RCCH along with a rate indication remains, NAK and stop command is not explicitly defined. 在可选实施例中,对应上述对方法750的可替代技术当中的任意一种,NAK且停止功能可以被采用。 In an alternative embodiment, any of the above method corresponding to 750 among the alternative technologies, NAK and stop functionality may be employed. 同样,如以上提到的关于方法750那样,在示例性实施例中,基于速率改变的速率控制或准许被在分组边界处执行。 Similarly, with respect to the method 750 As mentioned above, in an exemplary embodiment, the rate of change of the rate control or grant based on the packet boundary is performed. 预期所述的方法可以被修改成也合并内部子分组的速率改变。 The contemplated method may be modified to also incorporate the internal subpacket rate changes.

根据此处的原则,对于本领域的技术人员将会很清楚的是,在此所述的任意过程和特征可以以各种方式被组合。 The principle here, those skilled in the art will be clear that in this process and any of the features may be combined in various ways. 例如,移动台可以仅仅被主要的基站通过准许来控制,但不由其它基站通过速率控制比特来控制。 For example, the mobile station may only be controlled by the primary base station permitted, but not by other base stations controlled by the rate control bits. 可替代地,移动台可以通过来自所有基站的、或来自其活动集中的基站的子集的准许被控制。 Alternatively, the mobile station can, from a base station or a subset of its active set of base stations from all grant is controlled. 一些F-GCH可以被软组合。 Some F-GCH may be soft-combined. 移动台操作的模式可以在信道分配期间通过L3信令建立,或是在分组数据呼叫期间通过其它消息来建立。 Mode mobile station operation may be established by L3 signaling during channel assignment or via other messages established during a packet data call.

作为另一个实例,如果分组被正确接收到,则主要基站可以发送ACK一STOP或是ACK—RC。 As another example, if a packet is received correctly, the primary base station may send an ACK STOP or ACK-RC. 可以不使用速率控制命令,因此ACK_RC 可以被用于表示对于这种模式的"ACK且继续"。 Rate control command may not be used, thus ACK_RC may be used to represent this pattern "ACK and continue." 在这种上下文中,"ACK 且继续"指示移动台可以以与正在被确认的分组相同的速率发送新的分组。 In this context, "ACK and continue" indicates that the mobile station may transmit a new packet with the packet being acknowledged at the same rate. 如以前那样,如果ACK_STOP被发送,基站可以在指定到MS的F-GCH上发送越级准许(oveniding grant)。 As such, if ACK_STOP is sent, the base station may transmit on the specified leapfrog grant to the MS before F-GCH (oveniding grant). 在此实例中,除非相应的准许与NAK—起被发送,否则NAK将指示"NAK且停止"。 In this example, unless appropriate permits and NAK- from being sent, or NAK will indicate "NAK and stop." 在这种情况中,非主要基站也发送ACK^STOP或ACK^RC,其中ACK_RC并不伴随以速率控制命令,并且指示"ACK且继续"。 In this case, the non-primary base stations also send ACK ^ STOP or ACK ^ RC, where ACK_RC is not accompanied by a rate control command, and indicates "ACK and continue."

在另一种示例性特殊模式中,该模式合并了所述特征的子集,移动台仅仅可以通过速率控制比特(来自其F-RCCH活动集中的基站)被控制。 In another example special mode, incorporating a subset of the pattern of the feature, the mobile station can only be controlled by the bit rate (the base station from which the F-RCCH Active Set) is controlled. 这种模式可以在信道分配期间通过L3信令被建立或者在分组数据呼叫期间通过其它消息被建立。 This model can be established or during a packet data call is established through other messages via L3 signaling during channel assignment. 在这种模式中,如果分组没被成功接收到, In this mode, if the packet is not successfully received,

则基站发送NAK。 The base station transmits NAK. 当分组被正确接收到时,基站把F-RCCH (RATE_H OLD、 RATE—INCREASE、或RATE—DECREASE)连同ACK—STOP或是ACK—RC —起发送。 When a packet is received correctly, the base station the F-RCCH (RATE_H OLD, RATE-INCREASE, or RATE-DECREASE) together with the ACK-STOP or ACK-RC - starting transmission. 在最后一个子分组之后的NAK附带有F-RCCH (RATE一HOLD、 RATE—INCREASE、或RATE—DECREASE)。 In NAK after the last subpacket included with F-RCCH (RATE a HOLD, RATE-INCREASE, or RATE-DECREASE).

图10—12显示了说明的对在此所述的各种信道的定时的例子。 Figures 10-12 show an example of the timing of the various herein described channel. 这些实例并不代表任何对帧长度的特定选择,只是说明了对准许、ACK和速率控制(RC)指示符的相对定时。 These examples do not represent any specific choice of frame length, but illustrate the grant of, ACK, and rate control (RC) relative to the timing indicator. ACK指示符、RC指示符、和准许在相同的时间间隔期间发生,使得移动台为了下一个分组发射的应用在大致相同的时刻接收ACK、 RC和准许信息。 ACK indicator, the RC indicator, and the grant during the same time interval occurs, so that a mobile station for the next application receives the ACK packet transmitted at substantially the same time, RC and grant information. 在这些实例中,除了移动台接收到准许时或者所有子分组已经被发送时之外,移动台不需监视RC 指示符(如在以上示例性实施例中描述的那样)。 In these examples, in addition to or when all subpackets have been transmitted to the mobile station receives a grant, the mobile station need not monitor the RC indicator (as described in the above exemplary embodiment). 移动台监视分配给它的ACK比特或是分配给对于特定ARQ序列的RC指示符的ACK比特。 Mobile station monitors the ACK bit assigned to it, or assigned to a particular ARQ sequence for a RC indicator ACK bits. 例如,如果存在四个ARQ序列,并且移动台在所有ARQ序列上发送,那么移动台监视每个帧的ACK指示符和对每个帧的RC指示符(如果可用的话)的ACK指示符。 For example, if there are four ARQ sequences are present, and the mobile station transmits on all ARQ sequences, then the mobile station monitors the ACK indicator every frame and to the RC indicator ACK indicator (if available) for each frame. 在各次发射之间引入空帧,以为基站或移动台(如果可用的话),对请求、子分组发射、准许、确认和速率控制命令的接收和解码预留出时间。 Is introduced between each transmit a null frame, that base station or mobile station (if available), a request, transmit the sub-packet, grant, acknowledgment and rate control receiving and decoding the reserved time command.

注意的是,这些定时图并不是穷举的,而是仅仅用于说明上述的各方面。 Note that these timing charts are not exhaustive, but merely to illustrate various aspects described above. 本领域的技术人员将会认识到无数种序列的组合。 Those skilled in the art will recognize myriad combinations of sequences.

图10说明了对带有组合确认和速率控制信道的示例性实施例的定时。 Figure 10 illustrates the timing of an exemplary embodiment with a combined acknowledgment and rate control channels. 移动台在R-REQCH上发送发射请求。 The mobile station sends a request to transmit on the R-REQCH. 基站随后响应该请求在F-GCH 上发送准许。 The base station then transmits a response to the request grant on F-GCH. 然后移动台通过利用依照准许的参数来发送第一个子分组。 Then the mobile station by using a first sub-packet is transmitted in accordance with the permitted parameters. 如子分组发射的失败所指示的那样,在基站处子分组没有被正确解码。 The sub-packet transmission as indicated by the failure, is not decoded correctly at a base station sub-packet. 基站一起发送F-ACKCH上的ACK/NAK发射和F-RCCH上的速率控制命令。 The base station transmits the ACK together with the F-ACKCH / NAK transmission and the F-RCCH rate control command. 在此实例中,NAK被发送,并且F-RCCH上发射DTX。 In this example, NAK is transmitted, and transmit DTX on F-RCCH. 移动台接收NAK并重发第二子分组作为响应。 The mobile station receives the NAK and retransmits the second subpacket in response. 这次,基站正确地解码第二子分组,并再次一起发送F-ACKCH上的ACK/NAK发射和F-RCCH上的速率控制命令。 This time, the base station correctly decodes the second subpacket, and sends an ACK on the F-ACKCH along with re / NAK transmission and the F-RCCH rate control command. 在此实例中,没有发送附加的准许。 In this example, no additional grant transmitted. ACK—RC被发送,并且速率控制命令被发布(如根据期望的调度确定的那样,其可以指示增加、减小或保持)。 ACK-RC is transmitted, and the rate control command is issued (as determined in accordance with the scheduling as desired, which may indicate an increase, decrease, or remain). 然后,移动台通过利用与准许相关的、在必要时被下一个分组的第一子分组。 Then, by using the mobile station associated with the permit, when necessary, the first sub-packet is the next packet.

图11说明了对具有组合的确认和速率控制信道连同新准许的示例性实施例的定时。 Figure 11 illustrates the timing of acknowledgment and rate control channels having a composition along with an exemplary embodiment of a new grant. 请求、准许、子分组发射(没有被正确解码的)和NAK 被发送,与以上图10描述的第一组八个帧一样。 Request, grant, subpacket transmission (not decoded correctly) and NAK are transmitted the same as the first eight frames described above with FIG. 10. 在此实例中,第二个子分组发射也被正确接收到并被正确解码。 In this example, the second transmit subpackets also correctly received and decoded correctly. 但是,基站发送ACK一STOP, 而不是发送ACK一RC。 However, the base station transmits an ACK the STOP, rather than sending an ACK RC. 如果没有伴随ACK—STOP的准许,则移动台将恢复成自主发射。 If not accompanied by ACK-STOP grant, the mobile station would revert to autonomous transmission. 而新的准许被发送。 The new grant is transmitted. 移动台不需为这个帧监视F-RCCH。 The mobile station need not monitor the F-RCCH for this frame. 然后,移动台依照该新的准许发送下一个分组的第一子分组。 Then, the mobile station in accordance with the first sub permission by transmitting a new packet to packet.

图12说明了对具有组合的确认和速率控制信道但没有准许的示例性实施例的定时。 FIG 12 illustrates the timing of the exemplary embodiment has a combined acknowledgment and rate control channels, but not permitted to. 此实例与图10相同,除了没有准许被发送以响应原始的移动台请求之外。 This example of FIG. 10 are the same, except that no grant is sent in response to a mobile station other than the original request. 这样,第一分组的第一子分组发射被以自主速率发送。 Thus, the first subpacket transmission of the first packet is transmitted at a rate independent. 再一次,这个子分组在基站处被不正确地解码。 Again, this subpacket is decoded incorrectly at the base station. 第二个子分组被再一次正确解码,并且ACK—RC与速率控制命令一起被发送。 The second subpacket is again decoded correctly, and ACK-RC and rate control command is transmitted together. 然后,移动台以可能被调整的速率发送下一个分组。 Then, the mobile station may be adjusted to lower a transmission rate of packet. 这个实例说明了仅仅使用速率控制命令而没有任何准许地任意地改变移动台速率的可能性。 This example illustrates the use of the rate control commands only, without any possibility of the permitted mobile station rate arbitrarily changed.

注意的是,在可替换实施例中,基站可以使用利用自主发射的速率控制,其中自主发射可以带有或者不带有先前请求。 Note that, in an alternative embodiment, the base station may use the autonomous rate transmitted using a control, wherein the autonomous transmission may, with or without a previous request. 减少可以被用于缓解拥塞,并且当存在额外的容量时增加可以被授予,即使BS可能不知道数据请求,因为该请求没被发送。 Reduction may be used to relieve congestion, and when there is an additional increase in capacity can be granted, even though the BS may not know the data request because the request is not sent.

图13说明了包括专用速率控制信号和公共速率控制信号的系统100 的示例性实施例。 FIG 13 illustrates an exemplary embodiment includes a dedicated rate control signal and a common rate control signal 100. 专用速率控制信道(F-DRCCH)被从基站104发送到移动台106。 Dedicated rate control channel (F-DRCCH) is transmitted from the base station 104 to the mobile station 106. 如上所述,F-DRCCH实际上以与F-ACKCH和F-RCCH相同的方式,与前向确认信道(F-ACKCH) —起用于提供确认、继续准许和执行速率控制。 As described above, F-DRCCH fact with the F-ACKCH and F-RCCH in the same manner, with the forward acknowledgment channel (F-ACKCH) - for providing confirmation from, and allowed to continue to perform rate control. 基站可以向多个移动台当中的每一个发送专用速率控制信道。 The base station may send a dedicated control channel to each of mobile stations among a plurality of rates. 在此实例中,基站还发送公共速率控制信道(F-CRCCH)。 In this example, the base station also transmits a common rate control channel (F-CRCCH). 公共速率控制信道可以被用于同时控制一组移动台的速率。 Common rate control channel may be used to control a rate of the mobile station set.

图14说明了包括前向扩展确认信道(F-EACKCH)的系统100的实施例。 FIG 14 illustrates an embodiment of the system includes a forward extended acknowledgment channel (F-EACKCH) 100. F-EACKCH可以取代确认信道(即,上述的F-ACKCH)和速率控制信道(即,F-RCCH)。 F-EACKCH may be substituted with an acknowledgment channel (i.e., the above-described F-ACKCH) and a rate control channel (i.e., F-RCCH). 这两种信道的功能可以以与本发明各实施方案一致的方式被组合到一条信道中。 The two channel functions can be combined into one channel in various embodiments consistent with the present invention. F-EACKCH被从一个或多个基站104发送到一个或多个移动台106。 F-EACKCH is transmitted from one or more base stations 104 to one or more mobile station 106. 如上所述,并且按照以下将进一步详细说明的那样,f-crcch可以与f-eackch—起被发送。 As described above, according to the above and will be described in further detail, f-crcch from the f-eackch- can be transmitted. 然而,公共速率控制信道和扩展确认信道的概念不同,所有这二者不需要被组合(因此如图14中所示的,有代表f-crcch的虚线)。 However, different concepts of common rate control channel and extended acknowledgment channel, all of which need not be a combination of both (and therefore shown in Figure 14, there is the dashed line represents the f-crcch).

例如,f-ackch可以包括依照两比特数据模式(具有四种状态)的命令。 For example, f-ackch may include a command in accordance with the two-bit data pattern (having four states) of. ack且继续信息可以与数据速率增加的命令组合起来,作为第一状态。 ack and continue information may be combined with a command to increase the data rate, as the first state. ack且继续信息可以与数据速率减小的命令组合起来,作为第二状态。 ack and continue information may be combined with a reduced data rate command as a second state. ack且停止可以是第三状态,并且nak为第四状态。 ack and stop may be the third state and the fourth state nak. 这四种状态可以用根据公众已知技术的i和q调制格式星座来代表。 These four states can be represented in accordance with the publicly known art and i q modulation format constellations.

图15说明了适合f-eackch上使用的示例性星座。 FIG 15 illustrates an exemplary constellation suitable for use in the f-eackch. 如本领域已知的那样,可以使用正交调幅(qam)技术来利用这样的星座。 As is known in the art, may be used quadrature amplitude modulation (QAM) constellation with such techniques. 在可选实施例中,如所示那样,可以利用任意两个信号来将命令映射在两个维度上。 In an alternative embodiment, as, any two signals may be utilized to map commands in two dimensions in FIG.

在此实例中,七个点被分配给各个命令。 In this example, seven points are assigned to various commands. 空发射(o,o)点被分配给nak一hold。 Empty emission (o, o) point is assigned to a nak hold. 这可能是最有可能被发送的命令,因此这样分配可以保存发射功率和容量。 This is probably the most likely transmitted command, and therefore transmission power can be saved so that distribution and capacity. 被分配到圆周上的点的其它各个命令,如所示那样, 包括ack—increase 、 ack—hold 、 ack—decrease 、 nck—decrease、 nckjncrease和ack—stop。 Other commands are assigned to each point on the circumference, as shown, including ack-increase, ack-hold, ack-decrease, nck-decrease, nckjncrease and ack-stop. 这些命令中的每一个可以被作为单个qam调制符号发送。 Each of these commands may be sent as a single qam modulation symbols. 每个命令对应于在f-ackch 和f-rcch信道的模拟集合上发送的一对命令。 Each command corresponds to a pair of commands sent on an analog set f-ackch and f-rcch channel. ackjncrease指示: 以前的子分组被正确解码,并且将来的子分组可以以增加的速率发送。 ackjncrease indicated: previous subpacket was decoded correctly, and future subpackets may be sent at an increased rate. ack一hold指示,以前的子分组被正确解码,并且将来的子分组可以以现在的速率发送。 ack a hold indication, the previous subpacket was decoded correctly, and future subpackets may be sent at the current rate. ack_decrease指示:以前的子分组被正确解码, 并且将来的子分组可以被发送,尽管要以减小的速率发送。 ack_decrease indicated: previous subpacket was decoded correctly, and future subpackets may be sent, although at a reduced rate to be transmitted. ack—stop 指示:以前的子分组被正确解码,但任意以前的准许和/或速率控制命令被废除。 ack-stop indication: previous subpacket was decoded correctly, but any previous grant, and / or rate control commands are abolished. 移动台仅仅可以被转移到自主模式(如果可用的话)。 The mobile station may only be transferred to the autonomous mode (if available).

nakjncrease指示子分组没被正确解码。 nakjncrease indicating sub-packet has not been decoded correctly. 将来的发射应该以较高的速率(举例来说可能是由于容量限制放松)传送。 Future emission should be at a higher rate (for example, due to capacity restrictions may be relaxed) transmission. 在一个实施例中, 速率控制命令在最终的子分组发射之后被传送。 In one embodiment, the rate control command is transmitted after the final subpacket transmission. 可选实施方案便于在任意时刻具有nak的速率控制发射。 Alternative embodiment facilitates nak rate at any moment with the emission control. 以相似的方式,nak一decrease 指示:以前的子分组没有被正确解码,并且将来的发射必须以减小的速 In a similar manner, a decrease NAK indication: previous subpacket was not decoded correctly, and future emissions must be reduced in order to speed

50率进行。 50 rate. NAK一HOLD指示:以前的子分组没有被正确解码,并且将来的发射可以以现在的速率进行。 Indicating a NAK HOLD: previous subpacket was not decoded correctly, and future transmission may be made at the present rate.

在图15的实例中没有采用NAK一STOP命令,但本领域的技术人员会认识到,可以引入这样的命令(或其它命令)。 A NAK STOP command is not used in the example of FIG. 15, those skilled in the art will recognize that the introduction of such command (or other commands). 并且,用于编码NAK—STOP (以上详细说明的)的各种可选方案也可以与F-EACKCH — 起使用。 Also, various alternatives for encoding NAK-STOP (detailed above) may be the F-EACKCH - used together.

本领域的技术人员将认识到,通过合并命令的任意集合(或者其组合)可以采用许多种星座,如此处详细说明的那样。 Those skilled in the art will recognize that many types can be employed by any constellation set (or combinations thereof) were combined command, so that the detailed description. 星座可以被设计成对各种命令、命令集合或命令类型提供各种保护水平(g卩,正确接收的可能性)。 Constellation may be designed to various commands, or command types set of commands to provide various protection levels (g Jie, the possibility of correct reception).

图16说明了适于在F-EACKCH上使用的可选星座。 16 illustrates an alternate constellation suitable for use on the F-EACKCH. 此实例说明了对NAK命令的速率控制的迁移。 This example illustrates the migration rate NAK command control. 各种ACK命令包括ACK—HOLD、 ACK一INCREASE、 ACK一DECREASE和ACK—STOP。 Various ACK commands include ACK-HOLD, ACK a INCREASE, ACK DECREASE, and an ACK-STOP. 为了以上所述的原因,空命令(0,0)被分配给NAK。 For the reasons above, the null command (0,0) is assigned to NAK. 此外,可以看到NAK和任意的ACK命令之间的距离是相等的,并且能够被设置成任何值,以提供希望的对于NAK的差错概率。 Further, distance between a NAK and any ACK command is equal, and can be set to any value to provide the desired probability of error for the NAK.

各种不同星座可以被设计成具有期望特性的命令集合组。 Various constellations may be designed having desired properties set command group. 例如,NAK 命令可以被分配到相对地靠拢在一起的点,ACK命令可以被分配到相对地靠拢在一起的点,并且这两组可能被分隔以相对较大的距离。 For example, NAK commands may be allocated points relatively close together, the ACK commands may be allocated points relatively close together to, and these two groups may be separated by a relatively large distance. 通过哪种方式,尽管把一组中一种类型的命令误认为该组中另一个命令的可能性增加,但弄错组类型的可能性被相关减小。 By the way, although the type of a group command mistaken for another group in order to increase the likelihood, but the possibility of being mistaken associated group type is reduced. 因而,ACK很少有可能被误识别为NAK,反之亦然。 Accordingly, ACK less likely to be misidentified as a NAK, and vice versa. 如果减小、增加或保持被误识别,那么随后的速率控制命令可以被用来补偿。 If you decrease, increase or maintain misidentified, then a subsequent rate control command may be used to compensate. (注意的是,增加的指示在减小或保持被发送时,例如,可能会增加对系统中的其它信道的干扰)。 (Note that, while an increase indicates decrease, or remain to be transmitted, for example, may increase the interference to other channels in the system).

图17说明了适合在F-EACCH上采用的三维示例性星座。 17 illustrates an exemplary three-dimensional constellation suitable for use in the F-EACCH. 可以通过使用任意三个用来表示每个轴上的幅度的信号形成三维星座。 Three-dimensional constellation may be formed by using any three signals to indicate the magnitude of each axis. 或者,单个信号可以被时间复用,以传送在第一时间段内的一个或多个维度的信息,跟随一个或多个第二维度中的一个或多个附加维度的信息。 Alternatively, a single signal may be time multiplexed to transmit information in one or more dimensions in a first time period, following one or more additional dimension information of the one or more second dimensions. 本领域的技术人员会认识到这可以被扩展到任意多个维数。 Those skilled in the art will recognize that this can be extended to any number of dimensions. 在一个实例中, QAM信号和BPSK信号可以被同时发送。 In one example, QAM signal and a BPSK signal may be transmitted simultaneously. QAM信号可以传送x和y轴信息,而BPSK信号传送z轴信息。 QAM signals may be transmitted information x and y axes, while the BPSK signal transmitted z axis information. 星座生成技术在本领域内是众所周知的。 Constellation generation techniques are well known in the art.

图17的实例进一步说明了将ACK命令分组以与NAK命令分开的概念。 Example 17 further illustrates the concept of an ACK and a NAK command packet to separate. 注意的是,ACK—STOP、 ACK_DECREASE、 ACK—HOLD和ACKJNCREASE之间的相对距离小于任何ACK命令和NAK命令(在此实例中,包括NAK一HOLD、 NAKJNCREASE和NAK-DECREASE) 之间的距离。 Note that the relative distance between the ACK-STOP, ACK_DECREASE, ACK-HOLD and ACKJNCREASE less than the ACK command and any NAK command (in this example, comprises a NAK HOLD, NAKJNCREASE and NAK-DECREASE) distance between. 这样,比起速率命令,移动台很少可能会误解释确认命令。 In this way, compared to the rate of command, the mobile station is less likely to be misinterpreted confirmation command. 本领域的技术人员会应用此处的原理以形成包括任意命令集合的星座, 同时为命令平均地进行保护设置,或者以任意想要的方式进行保护分配。 Those skilled in the art will apply the teachings herein to form constellations comprising any set of commands, and a command set equally protected, protected or dispensed in any desired manner.

图18说明了方法750的实施例,用于处理在基站处接收到的发射, 包括适合如上所述的进程750采用的确认和速率控制。 FIG 18 illustrates an embodiment of a method 750 for processing the received transmit at a base station, including acknowledgment and rate process 750 as described above for use in the control. 回想到,在进程750之前,基站已经接收到以前的请求(若有的话),做出任何想要的准许,接收准许和自主发射,并执行包括了这些和其它因素的调度。 Recall that, prior to process 750, the base station has received previous requests (if any), any permission you want to make, and receiving grant autonomous launch and implementation of these and other factors, including scheduling.

进程750的这个实施例开始于方框1810。 This embodiment process 750 begins at block 1810. 基站依照以前执行的调度做出可应用的任意想要的准许。 The base station makes any desired granted in accordance with the applicable schedule previously performed. 在方框1820中,生成ACK或NAK命令以确认以前的发射。 In block 1820, generates ACK or NAK acknowledgment of previously transmitted command. 确认命令可以与用于扩展以前的准许的命令组合起来或者伴随该命令,或者可以与用于速率控制现存准许(包括自主发射的速率控制)的命令组合起来或者伴随该命令。 Confirmation command may be used in combination with the previous grant or command extensions accompanying the command, or may be used to rate control existing grant (including rate control of autonomous transmission) or a combination of a command accompanying the command. 在此描述的任何技术可以被用于方框1820的信令,包括分离的速率控制和确认信号以及组合的确认速率控制信号。 In any of the techniques described herein may be used for the signaling of block 1820, including separate rate control and acknowledgment signals as well as the combined acknowledgment rate control signal.

在方框1830中,ACK—STOP命令可以被发送,以指示移动台应该从以前的准许模式恢复到自主模式。 In block 1830, ACK-STOP command may be sent to indicate that the mobile station should resume mode from a previous grant to autonomous mode. 在此实例中,ACK—STOP也用于指引移动台从监视专用速率控信道(即,F-DRCCH)切换到监视公共速率控制信号(g卩,F-CRCCH)。 In this example, ACK-STOP is also used to direct the mobile station to switch from monitoring a dedicated rate control channel (i.e., F-DRCCH) to monitor a common rate control signal (g Jie, F-CRCCH). 在可选实施例中,其它命令可以被选择用来指示从专用速率控制信道到公共速率控制信道监视的转移。 In an alternative embodiment, other commands may be selected from a dedicated control channel used to indicate the rate of transfer to the common rate control channel monitoring. 用于此目的的特定命令可以被定义。 Specific command for this purpose may be defined. 该特定命令还可以通过使用星座上的一个或多个点被并入到组合信道上,或者其可以通过信令被传送。 The specific command may also be incorporated by using a plurality of points on a constellation, or to a combination of the channel, or it may be transmitted through signaling. 在方框1840 中, 一个或多个基站为隨后的自主发射提供确认。 In block 1840, one or more base stations provide acknowledgment for subsequent autonomous transmissions. 在方框1850中,公共速率控制于是被用于修改监视公共速率控制信道的一个或多个移动台的速率。 In block 1850, common rate control is then used to modify the rate of one or more mobile stations monitoring the common rate control channel. 然后该处理可以停止。 Then, the process can be stopped.

图19说明了用于响应公共和专用速率控制的方法1900的实施例。 19 illustrates an embodiment of a method for responding to common and dedicated rate control 1900. 可以在响应采用公共和专用速率控制组合的基站的移动台中釆用方法1900,如以上有关图7和18所述的那样。 Movement may be employed in response to a combination of common and dedicated rate control station preclude the use of a base station The method, as in claim 7 and about 181,900 as described above in FIG. 该处理开始于判断框1910。 The process begins at decision block 1910. 在此实例中,专用速率控制与准许一起被提供。 In this example, dedicated rate control is provided along with a grant. 不在准许控制下操作的移动台将监视公共速率控制信道。 The mobile station is not permitted to operate under the control of the common rate control channel monitoring. 在可选实施例中,在准许控制下操作的移动台也可以被命令来遵循公共速率控制信号,或者没被准许的移动台可以被分配专用速率控制信道。 In alternative embodiments, mobile stations operating under the control permission may be commanded to follow the common rate control signal, or is not permitted mobile station may be assigned a dedicated rate control channel. 这些可选方案没有在图19中说明,但根据此处的原理,本领域的技术人员将会通过使用各种信令技术而很容易地采用这样的实施例以及其修改。 These alternatives are not illustrated in FIG. 19, but according to the teachings herein, those skilled in the art will readily be employed such embodiments and modifications thereof using various signaling techniques. 在判断框1910中,如果移动台在以前准许的控制下操作,则前进至方框1940。 In decision block 1910, if the mobile station operates under the control of the previous grant, proceed to block 1940.

在方框1940中,移动台监视准许信道(g卩,F-GCH),确认和速率控制信道(如上所述,其可以是F-ACKCH和F-DRCCH,或组合的F-EACKCH)。 In block 1940, the mobile station monitors the grant channel (g Jie, F-GCH), acknowledgment, and rate control channel (as described above, which may be the F-ACKCH and F-DRCCH, or a combined F-EACKCH). 在方框1945中,如果ACK一STOP命令被接收到,则前进至方框1950。 In block 1945, if an ACK STOP command is received, the process proceeds to block 1950. 在此实施例中,如方框1950中所示的那样,ACK—STOP 被用于指定到自主发射的复原。 In this embodiment, as shown in block 1950, ACK-STOP is used to designate the emission of autonomous recovery. 如以下将进一步详细说明的那样, ACK—STOP也指示从监视专用速率控制信道转换到监视公共速率控制信道。 As will be explained in further detail, ACK-STOP also indicates transition from monitoring the dedicated rate control channel to monitoring the common rate control channel. 在可选实施例中,非ACI^STOP的命令可以被用于指示从专用速率控制信道监视到公共速率控制信道监视的切换,并且该命令不需要与用于恢复到自主发射的命令相同。 In an alternative embodiment, the non-ACI ^ STOP commands may be used to indicate from a dedicated rate control channel to monitoring the common rate control channel monitoring switch, and the command need not revert to autonomous transmission command for the same. 在方框1950之后,该处理可以停止。 After block 1950, the process may stop. 在示例性实施例中,当必要时,方法1卯0将被反复重复。 In an exemplary embodiment, when necessary, 0 to 1 d is repeated again.

在判断框1945中,如果ACK—STOP没被接收到,则前进至方框1955。 In decision block 1945, if the ACK-STOP is not received, the process proceeds to block 1955. 在方框1955中,移动台可以根据可能被接收到的ACK/NAK、速率控制、 和/或准许信道命令来发射。 In block 1955, the mobile station may be received according to ACK / NAK, rate control, and / or grant channel commands transmitted. 然后用于当前反复的处理可以停止。 Then repeated for the current process can be stopped.

返回到判断框1910,如果移动台当前没有在以前的准许的控制下操作,则前进至判断框1915。 Returning to decision block 1910, if the mobile station is not currently operating under a previous grant control, the process proceeds to decision block 1915. 在判断框1915中,如果在准许信道上接收到准许,则前进方框1920并根据接收到的准许发射,其后该处理可以停止。 In decision block 1915, if a grant is received in the channel grant, the process proceeds in block 1920 and transmit according to the received grant, after which the process may stop. 注意的是,在此实例中,如上所述,准许被用于指示移动台将监视专用速率控制信道。 Note that, in this example, as described above, permit the mobile station is used to indicate the dedicated rate control channel monitoring. 因此,在随后的对方法1900的重复中,这个移动台将从方框1910前进至方框1940,如上所述。 Thus, in a subsequent iteration of method 1900, this mobile station proceeds from block 1910 to block 1940, as described above. 在可选实施例中,可以采用可选 In an alternative embodiment, it may be used alternatively

技术来信号通知到专用速率控制监视的切换。 Technical signaled to the dedicated rate control monitoring switch.

在判断框1915中,如果准许没有被接收到,则移动台监视公共速率控制信道,如在判断框1925中显示的那样。 In decision block 1915, if grant is not received, the mobile station monitors the common rate control channel, as shown at decision block 1925. 如果公共速率控制命令被发布,则前进至方法1930。 If a common rate control command is issued, then the method advances to 1930. 移动台依照公共速率控制命令调整速率并可以 The mobile station in accordance with the common rate control command to adjust the speed and can

53接着以修改过的速率自主发射。 53 followed by the modified transmit rate independent. 然后该处理可以停止。 Then, the process can be stopped.

如果,在判断框1925中,公共速率控制命令没有被接收到,则前进至方框1935。 If, at decision block 1925, common rate control command is not received, the process proceeds to block 1935. 移动台可以接着以当前速率自主发射。 The mobile station may then transmit autonomously at the current rate. 然后该处理可以停止。 Then, the process can be stopped.

图20说明了方法750的可选实施例,该方法用于处理接收到的发射, 包括了如上所述适合与进程750 —样的使用的确认和速率控制。 FIG 20 illustrates a method 750 of the alternative embodiment, the method for transmitting and receiving process to include a process as described above for the 750 - identifying and controlling the rate of sample used. 此实施例说明了为组合确认和速率控制而对扩展确认信道(F-EACKCH)的使用。 This example illustrates the combination acknowledgment and rate control and extended acknowledgment channel used (F-EACKCH) a. 回想到,在进程750之前,基站已经接收到以前的请求(如果有的话),做出任意希望的准许,接收到准许和自主发射,并执行包括了这些和其它因素的调度。 Recall that, prior to process 750, the base station has received previous requests (if any), and make any desired permit, receiving the grant and autonomous launch and implementation of these and other factors, including scheduling.

进程750的这个实施例开始于方框2005。 This embodiment process 750 begins at block 2005. 基站依照以前执行的调度如可应用的那样做出任意希望的准许,该过程在方框2010中予以说明。 The base station as to make any desired scheduling grant in accordance with the previously executed application may, be the process described in block 2010. 在判断框2015中,响应以前接收到的发射确定ACK或NAK。 In decision block 2015, in response to the previously received transmission is determined ACK or NAK. ACK或NAK将被与速率控制组合起来以提供组合的F-EACKCH,以下将详细说明。 ACK or NAK will be combined with rate control to provide a combined F-EACKCH, described in detail below.

如果ACK要被传送,则前进至判断框2020。 If the ACK to be transmitted, the process proceeds to decision block 2020. 如果包括维持当前速率(即,ACK且继续)的速率控制被目标移动台所期望(如在以前步骤中执行的任意调度中确定的那样),则前进至判断框2030。 If the current comprising maintaining rate (i.e., the ACK and continue) rate control is desired target mobile station (as in any scheduling performed as determined in the previous step), then proceeds to decision block 2030. 在判断框2030 中,如果期望增加,前进至方框2035并在F-EACKCH上发送ACK一INCREASE。 In decision block 2030, if an increase is desirable, proceed to block 2035 and send an ACK INCREASE on the F-EACKCH. 然后该处理可以停止。 Then, the process can be stopped. 如果不期望增加,则在判断框2040中确定减少是否被期望。 If the increase is not desired, then decision block 2040 determines whether the desired reduced. 如果是,则前进至方框2045以在F-EACKCH上发送ACK—DECREASE。 If so, the process proceeds to block 2045 to transmit the ACK-DECREASE on the F-EACKCH. 然后该处理可以停止。 Then, the process can be stopped. 如果增加和减少都不被期望,则保持是合乎需要的。 If none are expected to increase and decrease, it is desirable to maintain. 前进至方框2050以在F-EACKCH上发送ACK_HOLD。 Proceeds to block 2050 to transmit on the F-EACKCH ACK_HOLD. 然后该处理可以停止。 Then, the process can be stopped. 注意的是,带有速率控制的这三个ACK命令也被用于扩展以前的准许。 Note that, with these three ACK rate control command can also be used to extend the previous grant.

在判断框2020中,如果速率控制不被期望,则在F-EACKCH上发送ACK—STOP,如方框2025中显示的那样。 In decision block 2020, if rate control is not desired, then the ACK-STOP transmitted on F-EACKCH, as shown in block 2025. 然后该处理可以停止。 Then, the process can be stopped. 当与诸如图18—19中说明的那样的实施例一起被利用时,例如,在该情况下公共和专用速率控制都被采用,ACK_STOP是能够指示移动台从专用速率控制监视转换到公共速率控制监视的命令的一个实例。 When combined with such embodiments when 18-19 is utilized with, for example, in which case the common and dedicated rate control are employed as described, ACK_STOP is capable of indicating the mobile station from a dedicated rate control to the common rate control monitoring translation an example of the command monitor. 在此实例中, ACK一STOP终止任意以前的准许,并且然后移动台将被转移到自主发射。 In this example, the ACK STOP a termination of any previous grant, and the mobile station will then be transferred to the autonomous transmission. 返回到判断框2015,如果ACK没有被发送,那么NAK处于可用状态。 Returning to decision block 2015, if the ACK is not sent, then the NAK is in a usable state. 如上所述,存在多种用于把速率控制和NAK组合起来的可选方案, 取决于NAK是否响应最后的子分组。 As described above, there are various alternatives for the NAK and rate control are combined, depending on whether the NAK is in response to the final subpacket. 在可选实施例中,那些可选方案也可以被并入到图20中说明的方法中。 In alternative embodiments, those alternatives may also be incorporated into the method illustrated in FIG. 20. 在此实例中,如果在判断框2055 中,NAK不响应最后的子分组,则前进至方框2060,以在F-EACKCH 上发送NAKJIOLD。 In this example, if at decision block 2055, the NAK is not in response to the final subpacket, proceed to block 2060 to transmit NAKJIOLD on F-EACKCH. 这个命令,如上所述,指示子分组没有被正确解码, 并且下一个子分组可以以当前速率发送。 This command, as described above, indicating the sub-packet is not correctly decoded, and the next subpacket may be transmitted at the current rate. 然后该处理可以停止。 Then, the process can be stopped.

在判断框2055中,如果NAK响应最后的子分组,前进至判断框2065。 In decision block 2055, if the NAK is in response to the final subpacket, proceed to decision block 2065. 如果不期望速率控制,则前进至方框2060以在F-EACKCH上发送NAKJHOLD,如上所述那样。 If rate control is not desired, proceed to block 2060 to transmit NAKJHOLD on F-EACKCH, as described above. 注意的是,在可选实施例中,附加的命令也可以被并入。 Note that, in an alternative embodiment, additional commands may also be incorporated. 例如,NAK一STOP可以被用于向子分组发送NAK, 同时废除以前的准许。 For example, a NAK STOP may be used to send the packet to the sub NAK, the abolition of the previous grant. 本领域的技术人员将会认识到许多种根据此处的原理的其它组合。 Those skilled in the art will recognize that many other combinations according to the principles described herein.

在判断框2065中,如果速率控制被期望,则前进至判断框2070。 In decision block 2065, if rate control is desired, proceed to decision block 2070. 如果增加被期望,则前进至方框2075以在F-EACKCH上发送NAKJNCREASE。 If the increase is desired, proceed to block 2075 to transmit NAKJNCREASE on F-EACKCH. 否则,前进至方框2085以在F-EACKCH上发送NAK一DECREASE。 Otherwise, the process proceeds to block 2085 to transmit on an F-EACKCH NAK DECREASE. 然后该处理可以停止。 Then, the process can be stopped. 注意的是,在此实例中,缺省的NAK,NAK—HOLD,如方框2060中所示的那样,是可从判断框2065 处达到的。 Note that, in this example, the default NAK, NAK-HOLD, as shown in block 2060, is reachable from decision block 2065. 如果可选实施例,即包括NAK^STOP的可选实施例被采用, 则与上述的方框2040—2050类似的附加判断路径可以被采用,来合并发送NAK一HOLD的可选路径。 If the alternative embodiment, i.e. including NAK ^ STOP alternative embodiment is employed, the above-described blocks 2040-2050 similar additional path determination may be employed, for a combined NAK is sent HOLD of alternative paths.

图21说明了用于接收和响应F-EACKCH的方法2100。 FIG 21 illustrates a method for receiving and responding to the 2100 F-EACKCH. 在一个实施例中,方法2100可以在响应根据上述的各种方法发射的基站的移动台中被采用,上述的各种方法包括在图7、 18和20中说明的那些方法。 In one embodiment, method 2100 may be transmitted in response to movement of the above-described various methods station the base station is employed, the above-described various methods include those described in FIG. 7, 18 and 20. 该方法开始于方框2110中,在该方框中移动台监视准许信道(g卩,F-GCH) 以确定准许是否已经被接收到。 The method begins at block 2110, the mobile station monitors the grant channel (g Jie, F-GCH) to determine whether a grant has been received in the box.

在方框2120中,移动台还响应以前发送的子分组监视F-EACKCH。 In block 2120, the mobile station further responsive to the monitoring sub-packets transmitted before F-EACKCH. 然后移动台根据F-EACKCH上的ACK或NAK指示发射或重传。 Then the mobile station transmits or retransmits according to the ACK or NAK indication on the F-EACKCH. 发射速率也依照F-EACKCH上的任意STOP、 HOLD、 INCREASE或DECREASE以及任意接收到的准许被修改。 Transmission rate in accordance with any STOP also on the F-EACKCH, HOLD, INCREASE, or DECREASE received and any grant is modified. 然后该处理可以停止。 Then, the process can be stopped.

以下进一步说明包括公共速率控制和专用速率控制的各种可选实施例。 The following illustrate various further comprising a common rate control and dedicated rate control alternative embodiment.

软切换中的移动台可以监视来自活动集中的所有小区的、来自其子集的、和仅仅来自服务小区的公共速率控制。 The mobile station in soft handoff may monitor all of the cells from the active set, from a subset thereof, and a common rate control from the serving cell only. 在一个示例性实施例中, In one exemplary embodiment,

仅仅在如果来自被监视的小区的集合的所有F-CRCCH信道指示数据速率的被许可的增加时,每个移动台才可以增加其数据速率。 Just indicate the data rate at all if the F-CRCCH channels from the set of monitored cells is permitted when increased, each mobile station can increase its data rate. 这可能便于改进的干扰管理。 This may allow for improved interference management. 如用此实例指示的那样,由于软切换中的各个移动台的活动集大小的差异,它们的数据速率可能不同。 As with this example, as indicated, due to differences in the size of the active set of the mobile stations in soft handover, their data rates may be different. 比起F-DRCCH, F-CRCCH可以被用于适应更多的处理增益。 Compared F-DRCCH, F-CRCCH can be used to accommodate more processing gain. 这样,对于相同的发射功率, 其固有地就可能是更可靠的。 Thus, for the same transmit power, it may be inherently more reliable.

回想到,速率控制能够被配置成公共速率控制(即,每扇区单个指示符)、专用速率控制(专用于单个移动台)、或组速率控制(在一个或多个组中的一个或多个移动台)。 Recall that rate control can be configured as common rate control (i.e., single indicator per sector), dedicated rate control (dedicated to a single mobile station), or group rate control (one or more in one or more groups mobile stations). 根据哪种速率控制模式被选择(其可以通过L3信令向移动台指示),移动台可以具有不同的对于速率调节的规则,其中该速率调节是基于速率控制比特,即特别是基于RATE—INCREASE和RATE_DECREASE的。 Which rate control mode is selected (which may indicate to a mobile station via L3 signaling) where the mobile station may have different rules for rate adjustment, wherein the rate adjustment based on rate control bits, i.e., in particular based RATE-INCREASE and RATE_DECREASE of. 例如,当是公共速率控制时,速率调节可以是随机的,而在当它是专用速率控制时是确定的。 For example, when a common rate control, rate adjustment may be random, while when it is dedicated rate control is determined. 根据此处的原则,其它各种改变将会很明显。 According to the principle here, other various changes will be apparent.

同样,在上述的各实例中,已假定速率控制是每HARQ信道的。 Also, in the examples described above, it has been assumed that rate control is per HARQ channel. 也就是,当移动台在最后的子分组之后接收到肯定确认或否定确认时,移动台只注意速率控制命令,并且确定对相同的ARQ信道上的下一次发射的速率调节。 That is, when the mobile station receives a positive acknowledgment or negative acknowledgment after the last subpacket, the mobile station only pay attention to rate control command, and determines the rate adjustment for the same ARQ channel at a transmission. 在重传的中间期间,其可以不注意速率控制命令。 During the middle of retransmission, which can not pay attention to rate control command. 因此, 基站不在重传的中间发送速率控制命令。 Thus, the base station does not retransmit the intermediate transmission rate control command.

对于公共速率控制或组速率控制来说,对以上规则的替换方案被预想到。 For common rate control or group rate control, the alternative to the above rule are envisioned. 特别是,基站可以在重传中间发送速率控制命令。 In particular, the base station may retransmit the control command in the middle of the transmission rate. 因此,移动台可以积累重传中间的速率控制命令,并将它们用于下一次分组发射。 Accordingly, the mobile station may accumulate rate control commands intermediate retransmission and transmit their packets for the next time. 在此实例中,我们假定速率控制仍然是每HARQ信道的。 In this example, we assume rate control is still per HARQ channel. 但是,F-ACKCH 和F-RCCH起到两条具有独立操作的信道的作用。 However, F-ACKCH and F-RCCH function as two channels with independent operation of. 这些技术还可以被推广至对所有ARQ信道(或是其子集)的速率控制。 These techniques can also be generalized to rate control for all ARQ channels (or a subset) of.
