发明领域 Field of the Invention

[0003] 本发明一般涉及无线通信,尤其涉及将授权、确认和速率控制信道组合起来。 [0003] The present invention relates generally to wireless communications, and more particularly to the authorization, validation and rate control channels are combined. 技术背景 technical background

[0004] 为了提供诸如话音和数据之类的各种通信,广泛部署了无线通信系统。 [0004] In order to provide various types of communication such as voice and data, the wireless communication systems are widely deployed. 典型的无线数据系统或网络为多个用户提供了对一个或多个共享资源的访问。 A typical wireless data system, or network provides access to one or more shared resources to a plurality of users. 一种系统可以使用多种接入技术,如频分复用(FDM)、时分复用(TDM)、码分复用(CDM)等。 A system may use multiple access techniques such as Frequency Division Multiplexing (FDM), time division multiplexed (TDM), Code Division Multiplexing (CDM), and the like.

[0005] 无线网络的例子包括基于蜂窝的数据系统。 Examples [0005] of wireless networks include cellular-based data systems. 一些这样的例子如下:(1) "TIA/ EIA-95-B Mobile Station-Base Station CompatibilityStandard for Dual-Mode Wideband Spread Spectrum Cellular System”(IS-95标准);(2)由名为“3rd Generation Partnership Project,,(3GPP)提供的标准(W-CDMA标准),其包含在一组文档3G TS 25. 21U3GTS 25. 212、3G TS 25. 213 和3G TS 25. 2 14 中;(3)由名为“3rdGeneration Partnership Project 2” (3GPP2)提供的标准(IS-2000 标准),其包含在“TR-45. 5 Physical Layer Standard for cdma2000 SpreadSpectrum Systems" φ ; (4) TIA/ EIA/IS-856标准(IS-856标准)的高数据速率(HDR)系统;(5) IS-2000标准的版本C,包括C. S0001. C至C. S0006. C ;相关的文档(包括后来的版本D提案)被称为IxEV-DV建议。 Some such examples are as follows: (1) "TIA / EIA-95-B Mobile Station-Base Station CompatibilityStandard for Dual-Mode Wideband Spread Spectrum Cellular System" (IS-95 standard); (2) by a consortium named "3rd Generation Partnership Project ,, (3GPP) standards provide a (W-CDMA standard), which is contained in a set of documents 25.213 and 3G TS 25. 2 in the 3G TS 25. 21U3GTS 25. 212,3G TS 14; (3) the name standard "3rdGeneration Partnership Project 2" (3GPP2) provided (iS-2000 standard), which is contained in "TR-45 5 Physical Layer standard for cdma2000 SpreadSpectrum Systems." φ; (4) TIA / EIA / iS-856 standard (iS-856 standard) the high data rate (HDR) system; (5) iS-2000 standard version of C, including C. S0001 C to C. S0006 C;.. related documents (including subsequent Revision D proposals) It is called IxEV-DV proposal.

[0006] 在一个示例性系统中,即IS-2000标准的版本D(当前正处于开发阶段)中,移动站在反向链路上的传输由基站控制。 [0006] In one exemplary system, i.e. IS-2000 standard version D (currently under development), the mobile station transmitting on the reverse link by a base station controller. 基站可以决定允许移动站发送的最高速率或业务与导频比(TPR)。 The base station may decide the maximum rate allowed to the mobile station or transmitted traffic-pilot ratio (TPR). 当前建议了两种控制机制:基于授权和基于速率控制。 The current proposed two control mechanisms: Based on the rate-based authorization and control.

[0007] 在基于授权的控制中,移动站向基站反馈关于移动站的发送能力、数据缓冲器大小、服务质量(QoS)等级等的信息。 [0007] In authorization-based control, a mobile station transmits feedback capability for the mobile station to the base station, data buffer size information, quality of service (QoS) level and the like. 基站监视来自多个移动站的反馈,决定允许哪一个移动站发送以及每个移动站所允许的相应最高速率。 The base station monitors feedback from a plurality of mobile stations, a mobile station determines which transmit and the corresponding maximum rate allowed for each mobile station allowed. 经由授权消息将这些决定传递到移动站。 These decisions via the authorization message is transmitted to the mobile station.

[0008] 在基于速率控制的控制中,基站使用有限的范围调整移动站的速率(速率上调、 不变或速率下调)。 [0008] In the control based rate control, using a limited range of the base station to adjust the rate of the mobile station (rate increase, or the rate of change down). 使用简单的二进制速率控制比特或多值指示,将调整命令传送到移动站。 Using a simple binary rate control bit or value indicates the adjustment command to the mobile station.

[0009] 在满缓冲器情况下,活动的移动站有大量的数据,此时,基于授权的技术和基于速率控制的技术工作基本上相同。 [0009] In the case where the buffer is full, a large number of mobile station activity data, this time, based on the authorized technical and technical work based rate control is substantially the same. 忽略开销问题,授权方法在真实业务模型的情况下能够更好地控制移动站。 Ignore the cost issue, the authorization method in case of a real business model to better control the mobile station. 忽略开销问题,授权方法能够更好地控制不同的QoS流。 Ignore the cost issue, the authorization method can better control different QoS streams. 可以区分两种速率控制类型,这包括:专用速率控制方法,给每个移动站单个比特;以及,公共速率控制, 每个扇区使用单个比特。 We can distinguish between two types of rate control, which includes: a dedicated rate control method, a single bit to each mobile station; and a common rate control, using a single bit per sector. 这两种方法的各种混合可以把多个移动站分配给一个速率控制比特。 Various methods of mixing the two may assign multiple mobile stations to a rate control bit. 公共速率控制方法需要的开销较少。 Less common rate control method requires overhead. 但是,与更专用的控制方案相比,它对移动站提供的控制也较少。 However, compared with a more dedicated control scheme, the mobile station controls its offer less. 当在任一时间进行发送的移动站的数量减少时,公共速率控制方法和专用速率控制方法彼此靠近。 When reducing the number of mobile station transmitted at any one time, the common rate control method and the dedicated rate control approach each other method.

[0010] 基于授权的技术能够快速地改变移动站的传输速率。 [0010] capable of changing the transmission rate of the mobile station quickly based authorization technique. 但是,如果存在继续的速率变化,则基于纯粹授权的技术会产生较高的开销。 However, if there is a rate of change continue, based on purely technical authorization will result in higher overhead. 同样,纯粹的速率控制技术会导致很慢的缓升时间(ramp-up times)和缓升时间内相同或更高的开销。 Similarly, a pure rate control technique will lead to a very slow ramp-up time (ramp-up times) and within the same or a higher overhead ramp time.

[0011] 上述方法都不能提供缩减的开销和很大或快速的速率调整。 [0011] above methods do not provide reduced overhead and large or rapid rate adjustments. 因此,本领域中存在缩减开销控制且能够在必要情况下调整传输速率的需求。 Thus, reducing the cost and controlling the transmission rate can be adjusted, if necessary, the need in the art exists.

发明内容 SUMMARY

[0012] 这里公开的实施例可以解决本领域中对于缩减开销控制且能够在必要情况下调整传输速率的需求。 [0012] Example embodiments disclosed herein may address the needs in the art for reduced overhead control, and the transmission rate can be adjusted if necessary in the. 根据一个方面,第一信号表示被解码子数据包的确认以及是否生成速率控制命令,当生成一个速率控制命令时,第二信号有条件地表示该速率控制命令。 According to one aspect, the first acknowledgment signal represents the control command decoded subpacket and whether generation rate, when generating a rate control command, a second signal conditionally indicates the rate control command. 根据另一方面,授权与确认可以同时生成。 According to another aspect, the authorization and confirmation may be generated simultaneously. 根据另一方面,移动站监视第一信号,根据第一信号所表明的情况,有条件地监视第二信号,并且,可以监视包括授权的第三信号。 According to another aspect, the mobile station monitors the first signal, a first signal according to the situation indicated, conditionally monitors the second signal, and may monitor a third signal comprising authorization. 根据另一方面, 一个或多个移动站发送一个或多个不同的信号。 According to another aspect, one or more mobile stations transmit one or more different signals. 还给出了其他各个方面。 Also it gives other aspects. 这些方面的优点是:当使用速率控制命令时,提供基于授权的灵活控制,以及利用较低的开销,从而提高系统利用率、增加容量和吞吐量。 The advantage of these aspects is that: when a rate control command, provides flexible control based on the authorization, and the use of low cost, thereby increasing system utilization, increasing capacity and throughput.

[0030] 图1是无线通信系统100的框图,无线通信系统100可以支持一种或多种CDMA标准和/或设计(例如,W-CDMA标准、IS-95标准、cdma2000标准、HDR规范、IxEV-DV系统)。 [0030] FIG. 1 is a block diagram of a wireless communication system 100, the wireless communication system 100 may support one or more CDMA standards and / or designs (e.g., W-CDMA standard, IS-95 standard, cdma2000 standard, the HDR specification, IxEV -DV system). 在其他实施例中,系统100还可支持除CDMA之外的任意无线标准或设计。 In other embodiments, the system 100 may support any wireless standard or design other than a CDMA. 在该示例性实施例中,系统100是IxEV-DV系统。 In the exemplary embodiment, system 100 is a IxEV-DV system.

[0031] 为简单起见,所示的系统100包括与两个移动站106进行通信的三个基站104。 [0031] The system 100 shown includes three base stations 104 in communication with two mobile stations 106 for simplicity. 基站及其覆盖区域常被统称为“蜂窝”。 The base station and its coverage area are often collectively referred to as a "honeycomb." 在IS-95、Cdma2000或IxEV-DV中,例如,一个蜂窝可以包括一个或多个扇区。 In IS-95, Cdma2000 or IxEV-DV, for example, a cell may include one or more sectors. 在W-CDMA规范中,基站的每个扇区以及该扇区的覆盖区域被称为“蜂窝”。 In the W-CDMA specification, each sector of the coverage area of ​​the sector and the base station is referred to as a "cell." 这里使用的术语“基站”可与术语“接入点”或“节点B”互换使用。 The term "base station" may be used herein with the term "access point" or "Node B" are used interchangeably. 术语“移动站” 可与术语“用户设备(UE) ”、“用户单元”、“用户站”、“接入终端”、“远程终端”或本领域中公知的其他对应术语互换使用。 The term "mobile station" with the term "user equipment (the UE)", "subscriber unit", "subscriber stations", "access terminal", "remote terminal" is well known in the art or the other of the respective terms are used interchangeably. 术语“移动站”包括固定的无线应用。 The term "mobile station" include fixed wireless applications.

[0032] 根据CDMA系统的实现,在任何给定时刻,每个移动站106可以通过前向链路与一个(或可能多个)基站104通信,并且,根据该移动站是否处于软切换状态,可以通过反向链路与一个或多个基站通信。 [0032] The CDMA system implemented, at any given moment, each mobile station 106 through the front and can, according to whether the mobile station is in soft handoff link with one (or possibly more) base stations 104 communicate,, It may communicate with one or more base stations via a reverse link. 前向链路(即下行链路)指的是从基站到移动站的传输,而反向链路(即上行链路)指的是从移动站到基站的传输。 The forward link (i.e., downlink) refers to transmission from the base station to the mobile station, and the reverse link (i.e., uplink) refers to transmission from the mobile station to the base station.

[0034] IxEV-DV前向链路数据传输 [0034] The front IxEV-DV forward link data transmissions

[0035] 系统100,例如IxEV-DV建议中描述的系统,通常包括四种类型的前向链路信道: 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)以及其他的备用信道。 [0035] The system 100, for example systems IxEV-DV proposal described, generally comprises a front four types of forward link channel: overhead channels, dynamically varying IS-95 and IS-2000 channels, a forward packet data channel (F -PDCH) and other alternate channel. 开销信道分配变化很慢,例如,它们可能数月不变。 Overhead channel allocation change is slow, for example, they may be unchanged for several months. 它们通常在产生重大网络配置变化时才改变。 They usually produce a significant change when the network configuration changes. 动态变化的IS-95和IS-2000信道是以每个呼叫为基础而分配的,或者,用于IS-95或IS-2000版本O到B的话音和分组业务。 Dynamic IS-95 and IS-2000 channels are allocated per call basis, or for IS-95 or IS-2000 version O B to the voice and packet services. 通常,在分配了开销信道和动态变化信道之后剩余的可用基站功率被分配给剩余数据业务的F-PDCH。 Typically, after the overhead channels and allocated dynamically change channels remaining available base station power is allocated to the remaining data traffic F-PDCH.

[0036] 与IS-856标准中的业务信道相类似,F-PDCH用于在某时间以最高可支持数据速率向每个蜂窝中的一个或两个用户发送数据。 [0036] and IS-856 standards is similar to the traffic channel, F-PDCH for a certain time at the highest supportable data rate to each cell transmits one or both of user data. 在IS-856中,当向移动站发送数据时,基站的全部功率和Walsh函数的全部空间都是可用的。 In IS-856, when transmitting data to the mobile station, all power and all the space of Walsh functions are available to the base station. 但是,在IxEV-DV系统中,一部分基站功率和一部分Walsh函数被分配给了开销信道以及现有的IS-95和cdma2000业务。 However, the IxEV-DV system, some base station power and a portion of the Walsh functions are allocated to overhead channels and existing IS-95 and cdma2000 services. 可支持的数据速率主要取决于在已经分配了用于开销、IS-95和IS-2000信道的功率和Walsh码之后可用的功率和Walsh码。 Supportable data rate mainly depends on the available have been allocated for later overhead, IS-95 and IS-2000 channels power and Walsh codes power and Walsh codes. 用一个或多个Walsh码对在F-PDCH上传输的数据进行扩频。 Spreading the data transmitted on the F-PDCH using one or more Walsh codes.

[0037] 在IxEV-DV系统中,基站在某一时间通常通过F-PDCH向一个移动站发送,尽管很多用户可能在使用蜂窝中的分组业务。 [0037] In the IxEV-DV system, the base station generally transmits to one mobile station through the F-PDCH at a time, although many users may be using packet services in a cell. (也可以向两个用户发送,通过合理地调度这两个用户的传输以及为每个用户分配功率和Walsh信道)。 (It may also be transmitted to two users by scheduling reasonable both users and the distribution of transmission power and Walsh channels to each user). 基于一些调度算法,选择进行前向链路传输的移动站。 Some scheduling algorithm, select the first mobile station based on the forward link transmission.

[0038] 在类似于IS-856或IxEV-DV的系统中,调度部分地基于来自正被服务的移动站的信道质量反馈。 [0038] In the IS-856 or similar IxEV-DV system, scheduling section based on the channel feedback from the mobile stations being service quality. 例如,在IS-856中,移动站估计前向链路质量和计算对于当前状况预期可持续的传输速率。 For example, in IS-856, the mobile station is estimated before the current transmission rate expected to persist and to the link quality calculations. 来自每个移动站的预期速率被传输到基站。 Expected rate from each mobile station is transmitted to the base station. 调度算法可以,例如, 选择支持较高传输速率的移动站进行传输,从而更高效地利用共享的通信信道。 The scheduling algorithm may, for example, choose to support a higher transmission rate of the mobile station for transmission to more efficient use of the shared communication channel. 再例如, 在IxEV-DV系统中,每个移动站发送载干比(C/I)估计值,作为对反向信道质量指示信道(R-CQICH)的信道质量估计。 As another example, in IxEV-DV system, each mobile station transmits a carrier to interference ratio (C / I) estimate as the channel quality indicator channel (R-CQICH) to the reverse channel quality estimation. 调度算法用于确定为传输所选择的移动站以及根据信道质量确定合适的速率和传输格式。 A transmission scheduling algorithm for determining the selected mobile station and determining the channel quality in accordance with the appropriate rate and transmission format.

[0039] 如上所述,无线通信系统100可以支持多个同时共享通信资源的用户,例如, IS-95系统可以在某时间将全部通信资源分配给一个用户,或者,例如,IS-856系统可以分配通信资源,以支持两种类型的接入。 [0039] As described above, the wireless communication system 100 may support multiple users sharing the communication resource simultaneously, e.g., IS-95 system, all the communication resources may be allocated to one user at a certain time, or, e.g., IS-856 system allocating communication resources to support both types of access. IxEV-DV系统是一种示例性的系统,在两种访问之间划分通信资源,并且,根据用户要求动态地进行分配。 IxEV-DV system is an exemplary system, the communication resource is divided between the two types of access, and, according to user requirements dynamically allocated. 前面刚刚描述了一种示例性的前向链路实施例。 Immediately above described embodiments An exemplary embodiment of a forward link before. 下面进一步详细描述各种示例性的反向链路实施例。 Described in further detail various exemplary embodiments of reverse link.

C/ I测量是用作信道估计的信道质量度量标准的一个例子,在其他实施例中,也可以使用其他信道质量度量标准。 C / I measurement is an example of channel estimation as channel quality metrics, in other embodiments, may use other channel quality metrics. 在基站104中,将C/I测量结果传送到传输子系统210,后面还将结合图3进一步详细描述它的示例。 In base station 104, the C / I measurement result is transmitted to the transmission subsystem 210, it will be combined later example of Figure 3 in further detail.

[0041] 传输子系统210通过反向链路将C/I估计传递到服务基站。 [0041] The transmission subsystem 210 via the reverse link C / I estimate is transmitted to the serving base station. 应当注意的是,在本领域公知的软切换情形中,从移动站发送的反向链路信号可由除服务基站之外的一个或多个基站接收,在这里将它们称为非服务基站。 It should be noted that, in the case of soft handover known in the art, the reverse link signal transmitted from the mobile station by a serving base station other than the one or more received base stations, where they are referred to as non-serving base station. 在基站104中,接收子系统230接收来自移动站106的C/I信息。 In base station 104, a receiving subsystem 230 receives the C / I information from mobile station 106.

[0042] 基站104中的调度器240用于确定是否应当以及如何将数据发送到服务蜂窝的覆盖区域内的一个或多个移动站。 [0042] The base station 104 scheduler 240 should be used to determine whether and how to transmit data to a cellular service within the coverage area of ​​one or more mobile stations. 在本发明的保护范围内,可使用任何类型的调度算法。 Within the scope of the present invention may use any type of scheduling algorithm. 1997 年2 月11 日提交的、题为“METHOD AND APPARATUS FOR FORWARD LINK RATESCHEDULING” 的美国专利申请No. 08/798,951中公开了一个例子,该申请已经转让给本发明的受让人。 US Patent No. 1997, filed February 11, entitled "METHOD AND APPARATUS FOR FORWARD LINK RATESCHEDULING" Application No. 08 / 798,951 discloses an example, the application has been assigned to the assignee of the present invention.

[0043] 在一个示例性的IxEV-DV实施例中,当从该移动站接收的C/I测量结果表明可以按特定速率发送数据时,选择进行前向链路传输的移动站。 [0043] In one exemplary embodiment IxEV-DV embodiment, when the mobile station received from the C / I measurement results show that data can be transmitted when a specific rate, for the mobile station to select the first transmission link. 考虑到系统容量,最好选择一个目标移动站,从而一直按最高可支持速率利用共享的通信资源。 Taking into account the system capacity, it is preferable to select a target mobile station, so that at the highest supportable rate has been the use of shared communication resources. 因此,所选择的典型目标移动站可以是具有所报告的最大C/I的移动站。 Thus, the typical target mobile station selected may be reported with a maximum C / I of the mobile station. 在调度决策中,还可以考虑其他因素。 In the scheduling decision may also consider other factors. 例如, 可以对各用户做出最低服务质量保证。 For example, you can make a minimum quality of service for each user is guaranteed. 可以选择具有所报告的较低C/I的移动站进行传输,从而维持到该用户的最低数据传输速率。 You may be selected having a lower reported C / I of the mobile station for transmission to the user to maintain a minimum data transfer rate. 也可以选择不具有所报告的最大C/I的移动站进行传输,从而在所有用户中维持特定的公正标准。 You may choose not to have reported the maximum C / I of the mobile station for transmission to maintain certain fairness criterion among all users.

[0044] 在该示例性的IxEV-DV系统中,调度器240确定向哪个移动站传输以及该传输的数据速率、调制格式和功率电平。 [0044] In this exemplary IxEV-DV system, scheduler 240 determines which mobile station and the data transmission rate to the transmission, modulation format, and power level. 在其他实施例中,如IS-856系统中,在移动站中可以基于在移动站中测量的信道质量,做出可支持速率/调制格式决策,并且,可以将传输格式发送给服务基站来取代C/I测量结果。 In other embodiments, such as IS-856 system, a mobile station may be based on channel quality measured at the mobile station, to make a supportable rate / modulation format decision, and may transmit the transmission format to the serving base station to replace the C / I measurements. 本领域技术人员应当认识到,可在本发明保护范围内使用可支持速率、调制格式、功率电平等的各种组合。 Those skilled in the art will recognize, may be used to support various combinations of rates, modulation format, power level, within the scope of the invention. 此外,在这里所述的各实施例中,调度任务是在基站中完成的,但在其他实施例中,调度过程的一部分或全部可以在移动站中执行。 Further, in the embodiment described herein, the scheduling tasks are performed in the base station of each embodiment, however, a portion or all of the scheduling process may be performed in the mobile station in other embodiments.

[0045] 调度器240指示传输子系统250使用选中的速率、调制格式、功率电平等通过前向链路向所选中的移动站发送。 [0045] The scheduler 250 uses the selected rate indicating a transmission subsystem 240, modulation format, power level transmitted to the selected mobile station via the forward link.

[0046] 在该示例性的实施例中,控制信道或F-PDCCH上的消息与数据信道或F-PDCH上的数据一起传输。 [0046] In the exemplary embodiment, the data message transmission on the data channel, or F-PDCH together on the control channel or F-PDCCH. 控制信道可用于标识F-PDCH上的数据的接收移动站,以及标识在通信会话过程中所用的其他通信参数。 A mobile station operable to receive control channel data on the identifier F-PDCH, as well as identifying other communication parameters in the communication session used. 当F-PDCCH表示某一移动站是传输目标时,该移动站应当接收和解码来自F-PDCH的数据。 When the F-PDCCH indicates a transfer destination is the mobile station, the mobile station should receive and decode the data from the F-PDCH. 在收到该数据之后,移动站在反向链路上用一条表示传输成功或失败的信息做出响应。 After receiving the data, the mobile station on the reverse link by transmitting information indicating a success or failure to respond. 本领域中所公知的重发技术广泛应用在数据通信系统中。 Well known in the art, a retransmission technique is widely used in data communication systems.

[0047] 移动站可以与一个以上的基站进行通信,这种情况被称为软切换。 [0047] The mobile station may communicate with more than one base station, this is called soft handover. 软切换可以包括来自一个基站(或一个基站收发机子系统BTS)的多个扇区以及来自多个BTS的多个扇区,前者被称为更软切换。 Soft handoff may include multiple sectors from one base station (or a base transceiver subsystem BTS) from a plurality of sectors and a plurality of BTS, the former is referred to as softer handoff. 软切换中的基站扇区通常存储在移动站的活动集合中。 Active base station sectors in soft handoff is typically stored in the mobile station set. 在同时共享通信资源系统中,如IS-95、IS-2000或IxEV-DV系统的相应部分中,移动站可以将从活动集合中所有扇区传输的前向链路信号进行组合。 Simultaneously shared communication resource system, such as sector transmission before all IS-95, IS-2000, or a corresponding portion of IxEV-DV system, the mobile station from the active set can be combined forward link signal. 在纯数据系统中,如IS-856或IxEV-DV 系统的相应部分中,移动站从活动集合中的一个基站接收前向链路数据信号,该基站是服务基站(是根据移动站选择算法确定的,如C. S0002. C标准中描述的算法)。 In a pure data system, such as IS-856 or corresponding portions IxEV-DV system, a mobile station from the active set of base stations receive forward link data signal, the base station is a serving base station (the mobile station selection algorithm is determined such algorithms C. S0002. C standard described). 也可以从非服务基站接收其他前向链路信号,它们的例子还将在后面做详细描述。 It may also be received from other non-serving base station forward link signals, examples of which will be described later in detail.

[0048] 可以在多个基站中接收来自该移动站的反向链路信号,对于活动集合中的基站, 通常维持反向链路的质量。 [0048] may receive reverse link signals from the mobile station in a plurality of base stations, base station to the active set, the quality of the reverse link is generally maintained. 可以将在多个基站接收的反向链路信号进行组合。 It may be combined in a plurality of reverse link signals received by base stations. 通常,将来自不同位置的基站的反向链路信号进行软组合(soft combine)需要很大的网络通信带宽以及很小的延迟,所以上面列出的示例性系统不支持这一点。 Typically, the reverse link signals from base stations different positions soft-combining (soft combine) requires a lot of network bandwidth and communication latency is very small, so the example systems listed above do not support it. 在更软切换中,在单个BTS中的多个扇区处接收的反向链路信号可以不用网络信令进行组合。 In softer handoff, reverse link signal at a plurality of sectors in a single BTS receives may be combined without network signaling. 在上述示例性系统中,虽然在本发明的保护范围内可以使用任何类型的反向链路信号组合,但是,反向链路功率控制维持着质量,从而使得在一个BTS (切换分集)处对反向链路帧进行成功解码。 In the exemplary system, although any type of reverse link signal combining within the scope of the present invention, however, the reverse link power control maintains quality such that at a the BTS (switching diversity) of The reverse link frames are successfully decoded.

[0062] 本节描述在设计无线通信系统的反向链路的一个示例性实施例时要考虑的各种因素。 [0062] This section describes various factors upon an exemplary embodiment of a reverse link of a wireless communication system designed to consider. 在下面进一步详细描述的很多实施例中,使用了与IxEV DV标准相关的信号、参数和过程。 Many further embodiments are described in detail below, we use the signal, parameters and procedures associated with the IxEV DV standard. 与这里描述的各个方面一样,对该标准的描述只是出于说明目的,并且,在本发明的保护范围内,其组合适用于任何数量的通信系统。 Various aspects As described herein, the standard description for illustrative purposes only, and, within the scope of the present invention is applicable to any number of combinations of communication systems. 该节用作本发明各个方面的部分总结,尽管它不是穷举的。 This section serves as part of the summary of various aspects of the present invention, although it is not exhaustive. 在后面的节中将对示例性的实施例做进一步的详细描述,其中,还描述附加的方面。 In later sections of exemplary embodiments will be further described in detail, in which additional aspects are also described.

[0063] 在很多情况下,反向链路容量是由干扰限制的。 [0063] In many cases, reverse link capacity is interference-limited. 基站根据各移动站的服务质量(QoS)要求,向移动站分配可用的反向链路通信资源,以高效利用,从而提高吞吐量。 The base station according to quality of service (QoS) requirements of each mobile station, allocating the available reverse link communication resources to the mobile station, efficient utilization, thereby increasing throughput.

[0064] 提高反向链路通信资源的使用率涉及很多方面。 [0064] improved utilization of the reverse link communication resource involves many aspects. 要考虑的一个因素是来自各移动站的被调度反向链路传输的混合,每个传输可能在给定时间经历变化的信道质量。 One factor to consider is the mix of scheduled reverse link transmissions from various mobile stations, each transmission may be at a given time experiencing varying channel quality. 为了提高总的吞吐量(蜂窝中所有移动站发送的全部数据),最好充分利用整个反向链路,一旦有反向链路数据待发送时。 To increase overall throughput (all data transmitted by all mobile stations in the cell), it is preferable to use the entire reverse link, when the time of the reverse link data to be transmitted. 为了填满可用的容量,可以授权移动站按照它们能够支持的最高速率进行访问,并且可以授权其他移动站访问,直至达到该容量为止。 To fill the available capacity, mobile stations may be authorized access to the highest rate they can support, and additional mobile stations may be authorized to access, until it reaches the capacity. 基站在决定对哪些移动站进行调度时要考虑的一个因素是每个移动站能够支持的最大速率以及每个移动站要发送的数据量。 A factor when deciding which base station the mobile station is scheduled to consider each mobile station can support a maximum rate of each mobile station and the amount of data to be transmitted. 可以选择支持更高吞吐量的移动站,而不选择信道不支持较高吞吐量的其他移动站。 Support higher throughput may be selected mobile station, a channel without selecting other mobile stations do not support higher throughput.

[0065] 要考虑的另一个因素是每个移动站所需要的服务质量。 [0065] Another factor to consider is that each mobile station required quality of service. 虽然可以抱着信道会改善的希望去推迟对一个移动站的访问而不选择较好位置的移动站,但是,为了满足最低质量的服务保障,可能需要授权未达最佳标准的移动站进行访问。 Although you can hold a channel of hope will improve access to postpone a mobile station and not choose a better location of the mobile station, however, in order to meet minimum quality of service guarantees, may need to authorize the mobile station suboptimal access . 因此,预定的数据吞吐量可能不是绝对的最大值,但在考虑了信道状况、可用移动站发射功率和服务要求的情况下是最大的。 Thus, the data throughput scheduled may not be the absolute maximum, but considering channel conditions, available mobile station transmit a case where power and service requirements are greatest. 所期望的是,任何配置都能够降低所选组合的信噪比。 It is desirable that any configuration can reduce signal to noise ratio of the selected combination.

[0066] 下面描述的各种调度机制能够使移动站在反向链路上发送数据。 [0066] The various scheduling mechanism described below can cause the mobile station to transmit data on the reverse link. 一种类型的反向链路传输涉及:移动站请求在反向链路上进行发送。 One type of reverse link transmission involves: a mobile station transmits a request on the reverse link. 基站判断是否存在满足该请求的可用资源。 The base station determines whether there are resources available to satisfy the request. 可以做出授权,以准予发送。 You can make authorization to grant sent. 在可以发送反向链路数据之前,移动站和基站之间的该握手引入了延迟。 Before the reverse link data can be transmitted between the mobile station and the base station introduces a delay of the handshake. 对于特定类型的反向链路数据,延迟可能是可接受的。 For certain types of reverse link data, the delay may be acceptable. 其他类型可能对延时更敏感,下面详细描述的用于反向链路传输的其他技术可以降低延迟。 Other types may be more sensitive to delay, other techniques described in detail below for the reverse link transmission delay can be reduced.

[0067] 此外,为了请求传输,需要消耗反向链路资源,为了响应该请求,需要消耗前向链路资源,即,发送授权。 [0067] In addition, the request for transmission, the reverse link resources consumed, in response to this request, prior to the need to consume resources link, i.e., transmission authorization. 当移动站的信道质量很低时,即远离基站(low geometry)或深衰落情况下,在前向链路上到达移动站所需的功率会较高。 When the mobile station channel quality is low, i.e., away from the lower base (low geometry) or deep fading, the preceding power required to reach the mobile station on the forward link will be high. 下面描述的各种技术可以降低反向链路数据传输所需的请求以及授权的数量或所需发射功率。 Various techniques described below may be required to reduce the reverse link data transmission request and the authorization number or required transmit power.

[0068] 为了避免由请求/授权握手引入的延迟以及节约支持它们所需的前向和反向链路资源,支持自动的反向链路传输模式。 [0068] In order to avoid a handshake request / authorization and saving the delay introduced by the forward and reverse links to support the resources they need to support reverse link transmission mode automatically. 移动站可以在反向链路上以有限的速率发送数据, 而不发出请求或等待授权。 The mobile station may transmit data at a limited rate on the reverse link without waiting for a request, or authorization.

[0069] 还期望修改根据授权或在没有授权开销的情况下自动发送的移动站的传输速率。 [0069] The authorization further desirable to modify the transmission rate of the mobile station or automatically sent without authorization overhead. 为此,可以将速率控制命令与自动和基于请求/授权的调度实现在一起。 To this end, the rate control command may be automatic and based on a request / authorization scheduling implemented together. 例如,一组命令可以包括一条增加、降低和维持当前传输速率的命令。 For example, a set of commands may include an increase, decrease, and maintain the current transmission rate command. 这样的速率控制命令能够独立地寻址到每个移动站,或多组移动站。 Such rate control command can be individually addressed to each mobile station, or group of mobile stations. 下面详细描述各种示例性的速率控制命令、信道和信号。 The following detailed description of various exemplary rate control commands, channels and signals.

[0070] 基站将一部分反向链路容量分配给一个或多个移动站。 [0070] The base portion of the reverse link capacity allocated to one or more mobile stations. 对授予访问权的移动站给予最高功率电平。 Given the highest power level to grant access to the mobile station. 在这里描述的示例性实施例中,反向链路资源是利用业务与导频(T/P) 比来分配的。 Exemplary embodiments described herein, the reverse link resources using traffic-to-pilot (T / P) ratio distribution. 由于每个移动站的导频信号都是通过功率控制进行自适应控制的,所以,指定T/P比表示在反向链路上发送数据的可用功率。 Since the pilot signal of each mobile station is adaptively controlled pilot by the power control, therefore, specified T / P ratio indicates the available power to transmit data on the reverse link. 基站可以对一个或多个移动站给予特定的授权,指明对于每个移动站特定的T/P值。 The base station may be given specific authorization to one or more mobile stations, indicating a particular T / P values ​​for each mobile station. 基站还可以对具有所请求访问的剩余移动站给予公共授权,以指示允许这些剩余移动站进行发送的最大T/P值。 The base station may also be administered for the remaining common authorize the mobile station having requested access, indicating these remaining mobile stations to allow the maximum T / P value transmitted. 下面进一步详细描述自动和受调度的传输、单独和公共授权以及速率控制。 And described in further detail by automatically scheduled transmission, individual and common rate control and authorization.

[0071] 各种调度算法在本领域内是公知的,还有更多算法有待开发,它们可用于根据注册移动站的数量、移动站自动传输的概率、未解决请求的数量和大小、对授权的预期平均响应以及任何数量的其他因素,确定授权的各种特定和公共T/P值以及预期速率控制命令。 [0071] The various scheduling algorithms are well known in the art, and many more algorithms to be developed, which may be used according to the probability of the number of registered mobile stations, the mobile station of the automatic transmission, the number and size unresolved request for authorization the expected average response, and any number of other factors, to determine the various specific and common authorized T / P value and the expected rate control command. 在一个示例中,基于服务质量(QoS)优先级、效率以及从这组请求移动站可完成的吞吐量, 做出选择。 In one example, based on quality of service (QoS) priority, efficiency, and requests the mobile station from the set of achievable throughput, to make a choice. 在2003 年8 月28 日提交的、题为“SYSTEMAND METHOD FOR A TIME-SCALABLE PRIORITY-BASEDSCHEDULER”的公共待决美国专利申请No. 10/651, 810中公开了一种示例性的调度技术,该申请已转让给本发明的受让人。 In 2003, filed August 28, entitled "SYSTEMAND METHOD FOR A TIME-SCALABLE PRIORITY-BASEDSCHEDULER" public pending US Patent Application No. 10/651, 810 discloses an exemplary scheduling techniques, the application assigned to the assignee of the present invention. 其他的参考资料包括题为“METHOD AND APPARATUS FOR REVERSE LINKRATESCHEDULING” 的美国专利5,914,950 和题为“METHOD ANDAPPARATUS FOR REVERSE LINK RATE SCHEDULING” 的美国专利5,923,650,它们都已转让给本发明的受让人。 Other references include, entitled "METHOD AND APPARATUS FOR REVERSE LINKRATESCHEDULING" US Patent No. 5,914,950, entitled "METHOD ANDAPPARATUS FOR REVERSE LINK RATE SCHEDULING" US Patent No. 5,923,650, which are assigned to this assignee of the invention.

[0072] 移动站可以用一个或多个子数据包来发送一个数据包,其中,每个子数据包包含完整的数据包信息(各子数据包不必编码相同,对于各子数据包,可以使用不同的编码或冗余)。 [0072] The mobile station may use one or more sub packets to send a data packet, wherein each subpacket contains the complete packet information (each subpacket is not necessary the same coding for each of the sub-packets may use different encoding or redundancy). 可采用重发技术,例如,自动重复请求(ARQ),来确保可靠的传输。 Retransmission techniques may be employed, for example, an automatic repeat request (the ARQ), to ensure reliable transmission. 因此,如果收到的第一个子数据包没有差错(例如,使用CRC),则向移动站发送一个肯定性确认(ACK),而不再发送附加的子数据包(每个子数据包以一种形式或其他形式包括完整的数据包信息)。 Thus, if a first sub-packet is received without error (e.g., using the CRC), it transmits a positive acknowledgment (ACK) to the mobile station, instead of sending additional sub-packets (each packet to a sub- forms or other forms include the complete packet information). 如果第一个子数据包未被正确接收,则向移动站发送一个否认信号(NAK),然后再发送第二个子数据包。 If the first sub-packet is not correctly received, the mobile station sends a negative acknowledgment signal (NAK), and then transmits a second sub-packet. 基站可以将这两个子数据包的能量进行组合,并尝试解码。 The base station may energy these two sub-packets are combined, and attempts to decode. 该过程可以无限地重复,但通常要指定子数据包的最大数量。 The process may be repeated indefinitely, but usually to specify the maximum number of sub-packets. 在这里描述的示例性实施例中,最多可以发送四个数据包。 In the exemplary embodiments described herein, up to four packets may be transmitted. 因此,当收到附加子数据包时,正确接收的概率得到了提高。 Thus, when the received additional sub-packet, the probability of correct reception is improved. 下面详细描述将ARQ响应、速率控制命令和授权进行组合的各种方式,以提供具有预期程度灵活度和可接受开销程度的传输速率和。 ARQ will be described in detail below in response to the rate control commands and authorization combined in various ways to provide a transmission rate having a desired degree of flexibility and cost and acceptability.

[0073] 正如前面所述,在决定是否使用自动传输来传输具有低时延的数据或者请求较高速率传输和等待公共或特定授权时,移动站可以在吞吐量和时延之间进行折衷。 [0073] As mentioned previously, in deciding whether to use the automatic transmission to transmit data with low latency or requesting a higher rate transfer and waiting for a common or specific authorization, the mobile station may trade off between latency and throughput. 此外,对于给定的T/P,移动站可以选择数据速率来适应时延或吞吐量。 In addition, for a given T / P, the mobile station may select a data rate to suit latency or throughput. 例如,如果移动站的传输比特较少,就可以确定低时延较好。 For example, if the transmission bit less mobile station, preferably a low latency can be determined. 对于可用的T/P(在该例子中可能是自动传输最大值,但也可以是特定或公共授权Τ/Ρ),移动站可以选择速率和调制格式,从而使基站正确接收到第一个子数据包的概率很高。 For the available T / P (in this example, the automatic transmission may be a maximum value, but may also be public or specific authorization Τ / Ρ), the mobile station may select a rate and modulation format such that the base station correctly receiving the first sub a high probability of data packets. 在必要情况下,可以进行重发,但是,该移动站很有可能足以在一个子数据包中发送其数据比特。 If necessary, can be retransmitted, however, the mobile station is likely to be sufficient to transmit its data bits in one sub-packet. 在这里描述的各示例性实施例中,每个子数据包在5毫秒的时间段内传输。 Various exemplary embodiments described herein, each subpacket transmitted in the 5 ms period. 因此,在该示例中,移动站可以立即执行自动传输,在5毫秒的时间间隔后就很可能在基站接收到它。 Thus, in this example, the mobile station can perform an automatic transmission immediately, it is likely received at the base station after a 5 ms interval. 当然,应当注意的是,移动站可以使用附加子数据包的有效性来提高对于给定Τ/Ρ所传输的数据量。 Of course, it should be noted that the validity of the mobile station may use the additional subpackets to increase the amount of data for a given Τ / Ρ transmitted. 所以,移动站可以选择自动传输来降低与请求和授权相关的时延,并且还可以将吞吐量和特定Τ/Ρ进行折衷来降低所需的子数据包的数量(因此也降低时延)。 Therefore, the mobile station may choose to automatically transmit request and grant related to reduced delay, and may also be a certain and specific Τ / Ρ compromise to reduce the number of required sub packets (time delay is also reduced). 即使选择了全部的子数据包,对于较小的数据传输,自动传输也比请求和授权的时延要低。 Even if all of the sub-packet selection, for smaller data transmission, the automatic transmission is also lower than request and grant delay. 本领域技术人员应当理解,当要传输的数据量增加从而需要发送多个数据包时,可以通过切换到请求和授权格式来降低总时延,因为请求和授权的不利结果将最终由多个数据包的较高数据速率的增加吞吐量抵消。 Those skilled in the art will appreciate, when the amount of data to be transmitted is increased so that a plurality of data packets to be transmitted, the overall delay can be reduced by switching to a request and grant format, since the negative result of the request and grant will eventually be a plurality of data higher data rates increase throughput packet offset. 下面用一组可与各种T/P分配相关联的示例性传输速率和格式进一步详细描述该过程。 Following by a set of various T / P associated dispensing example transmission rate and format of this process is further described in detail.

[0074] 反向链路数据传输 [0074] The reverse link data transmission

[0075] 反向链路设计的一个目标是:只要存在待发送的反向链路数据,就使在基站处的热噪声增加量(RoT)保持相对稳定。 [0075] A reverse link design goal is: as long as the reverse link data to be transmitted exists, it is relatively stable holding amount of increase in thermal noise (the RoT) at the base station. 反向链路数据信道上的传输是在三种不同的模式下处理的: Transmitting reverse link data channel is processed in three different modes:

[0076] 自动传输:该情况用于需要低延迟的业务。 [0076] Automatic Transmission: This case requires a low latency service. 移动站可以按照高达由服务基站确定(即,移动站将其信道质量指示(CQI)发送到的基站)的特定传输速率立即进行发送。 The mobile station may transmit up to now in accordance with the determined by the serving base station (i.e., the mobile station channel quality indication (CQI) transmitted to the base station) the particular transmission rate. 服务基站也被称为调度基站或授权基站。 The serving base station is also called scheduling base station or authorization. 自动传输的最大容许传输速率可由服务基站基于系统负荷、拥塞状况等来动态地告知。 Maximum allowable transmission rate of the automatic transmission may inform the serving base station dynamically based on system load, congestion status.

[0077] 受调度传输:移动站发送其缓冲器大小、可用功率以及其他可能参数的估计值。 [0077] the scheduled transmission: estimation value of the mobile station sends its buffer size, available power, and possibly other parameters. 基站确定何时允许移动站发送。 The base station determines when the mobile station allowed to transmit. 调度器的目的在于限制同时传输的数量,从而降低移动站之间的干扰。 The scheduler object is to limit the number of simultaneous transmissions, thus reducing the interference between mobile stations. 调度器可以让移动站在蜂窝之间的地带中以较低速率发送,从而降低对相邻蜂窝的干扰,以及严格地控制RoT,从而保护R-FCH上的话音质量、R-CQICH上的DV反馈和确认(R-ACKCH),以及系统的稳定性。 Scheduler may allow mobile station in the zone between the cell transmission at a lower rate, so as to reduce interference to neighboring cells, and strictly controlling the RoT to protect the voice quality on the R-FCH, DV on the R-CQICH feedback and acknowledgment (R-ACKCH), as well as stability of the system.

[0078] 速率控制传输:不管移动站是受控(即得到授权)还是自动发送,基站都可以通过速率控制命令调整传输速率。 [0078] The transmission rate control: Whether a mobile station is controlled (i.e., authorized) or automatic transmission, the base station may adjust the transmission rate control command throughput rate. 速率控制命令的例子包括增加、降低或保持当前速率。 Examples of rate control commands include increasing, decreasing, or holding the current rate. 可以包括附加的命令,以指明如何实现速率改变(即增加或减少量)。 It may include additional command, which specified how to achieve a rate of change (i.e., increase or decrease amount). 速率控制命令可以是概率性的或确定性的。 The rate control commands may be probabilistic or deterministic.

[0079] 这里描述的各实施例包含一个或多个特征,用于提高无线通信系统的反向链路的吞吐量、容量和总系统性能。 [0079] The various embodiments herein certain embodiments include one or more features for a reverse link of a wireless communications system is described, capacity, and overall system performance. 对IxEV-DV系统的数据部分尤其是增强反向补充信道(R-ESCH)上各移动站的传输优化的描述仅仅出于说明目的。 The data portion IxEV-DV system, especially for an enhanced reverse supplemental channel (R-ESCH) describes transmission of each mobile station to optimize the purposes of illustration only. 该节详细描述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 describes in detail 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一个子集。 These channels are generally a subset of channels in a communication system used.

[0080] 图4示出了反向链路数据通信的数据和控制信号的一个示例性实施例。 [0080] FIG 4 illustrates an exemplary embodiment of data and control signals reverse link data communication. 所示的移动站106正在通过各种信道进行通信,每个信道连接到一个或多个基站104A-104C。 The mobile station 106 are shown communicating through a variety of channels, each channel connected to one or more base stations 104A-104C. 基站104A被标为调度基站。 The base station 104A is labeled as the scheduling base station. 其他基站104B和104C是移动站106的活动集合的一部分。 Other base stations 104B and 104C are part of an active set of the mobile station 106. 图中示出了四种类型的反向链路信号和四种类型的前向链路信号。 There is shown a forward link signal of four types of reverse link signals and four types. 下面对其进行说明。 The following description thereof.

[0081] R-REQCH [0081] R-REQCH

[0082] 移动站使用反向请求信道(R-REQCH)来请求从调度基站进行反向链路数据传输。 [0082] the mobile station using a reverse request channel (R-REQCH) request for scheduling reverse link data transmission from the base station. 在该示例性实施例中,请求在R-ESCH上传输(下面将做进一步的详细说明)。 In the exemplary embodiment, transmits a request (which will be further described in detail) on the R-ESCH. 在该示例性实施例中,R-REQCH上的请求包括移动站能够支持的T/P比、根据变化信道状况的变量以及缓冲器尺寸(即,等待传输的数据量)。 In the exemplary embodiment, a request on the R-REQCH includes a mobile station capable of supporting the T / P ratio, and the variable buffer size according to changes in channel conditions (i.e., the amount of data waiting for transmission). 该请求也可以指明等待传输的数据的服务质量(QoS)。 The request may also indicate the quality of the transmission wait data service (QoS). 应当注意的是,移动站可以具有对于该移动站的单个特定QoS等级,或者,对于不同类型业务选项的不同QoS等级。 It should be noted that, the mobile station may have a single QoS level specified for the mobile station, or for different types of service options for different QoS classes. 高层协议可以指明各种数据业务的QoS或其他预期参数(如延时或吞吐量要求)。 Various higher layer protocols may indicate the QoS, or other data traffic expected parameters (such as latency or throughput requirements). 在另一实施例中,与其他反向链路信号,如反向基本信道R-FCH(例如,用于话音业务),组合起来使用的反向专用控制信道(R-DCCH),可用来承载接入请求。 In another embodiment, other reverse link signals, such as the reverse fundamental channel R-FCH (e.g., for voice traffic), combined reverse dedicated control channel (R-DCCH) used, it can be used to carry access request. 通常,接入请求可被描述为包括逻辑信道,即,反向调度请求信道(R-SRCH),可以将其映射到任何现有物理信道上,例如R-DCCH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 existing physical channel, such as the R-DCCH. 该示例性实施例向后兼容现有的CDMA系统,如IS-2000 版本C,并且,R-REQCH是物理信道,故可用于不存在R-FCH或R-DCCH的场合。 This exemplary embodiment is backward compatible with existing CDMA systems such as IS-2000 version of C, and, R-REQCH is a physical channel, R-FCH it can be used, or where s R-DCCH is not present. 为清楚起见,术语“R-REQCH”用于描述该实施例说明中的接入请求信道,但本领域技术人员可以很容易地将这些原理扩展到任何类型的接入请求系统中,而不管接入请求信道是逻辑的或物理的。 For clarity, the term "R-REQCH" used to describe the embodiments described the access request in this embodiment a channel, those skilled in the art can readily extend the principles to any type of access request system, regardless of the contact the request channel is logical or physical. 在需要请求之前,可以关断R-REQCH,从而降低干扰和节约系统容量。 Before the request needs to be turned off R-REQCH, thus reducing interference and conserving system capacity.

[0083] 在该示例性实施例中,R-REQCH有12个输入比特,包括以下:4个比特,指明移动站能够支持的最大R-ESCH T/P比;4个比特,指明移动站的缓冲器中的数据量;4个比特,指明QoS0本领域技术人员应当理解的是,在其他实施例中,可以包括任何数量的比特和各种其他字段。 [0083] In the exemplary embodiment, R-REQCH has 12 input bits, comprising the following: 4 bits, indicating the mobile station can support a maximum R-ESCH T / P ratio; 4 bits, indicating the mobile station the amount of data in the buffer; 4 bits, indicating QoS0 skilled in the art will appreciate that in other embodiments, may include any number of bits and various other fields.

[0084] F-GCH [0084] F-GCH

[0085] 从调度基站向移动站发送前向授权信道(F-GCH)。 [0085] from the front to the mobile station transmits the scheduling base station to grant channel (F-GCH). F-GCH可以包括多个信道。 F-GCH may include a plurality of channels. 在该示例性实施例中,采用公共F-GCH信道来做出公共授权,采用一个或多个独立的F-GCH信道来做出单独的授权。 In the exemplary embodiment, employ a common F-GCH channel is authorized to make public, the use of one or more individual F-GCH channels to make a separate authorization. 由调度基站做出授权,以响应相应R-REQCH上来自一个或多个移动站的一个或多个请求。 Authorized by the base station to make scheduling, in response to respective one or more requests from one or more mobile stations on the R-REQCH. 可将授权信道标为GCHx,其中,下标χ表示信道编号。 Grant channel may be denoted GCHx, wherein the subscript χ represents the channel number. 信道编号O可用来表示公共授权信道。 O channel number used to indicate the common grant channel. 如果采用了N个不同信道,则下标χ范围为1至N。 If N different channels, the subscript χ ranges from 1 to N.

[0086] 对一个或多个移动站,可以做出独立的授权,每个授权准予所识别的移动站在R-ESCH上按指定的T/P或更低发送。 [0086] one or more mobile stations may be authorized to make independent, each identified as authorized mobile station on the R-ESCH at specified T / P or less transmission. 在前向链路上做出授权会很自然地引入开销,因为使用了一些前向链路容量。 Authorization to make a forward link will naturally introduce overhead, because of the use of some forward link capacity. 这里详细描述用于降低与授权相关联的开销的各种方法,并且,根据这里公开的内容,其他方法对于本领域技术人员也是显而易见的。 Described in detail herein with various methods for reducing the overhead associated with the authorization, and based on the content disclosed herein, other methods for the skilled person are also apparent.

[0087] 一个考虑是,移动站的位置使得每个移动站经历变化的信道质量。 [0087] One consideration is the position of the mobile station so that the channel quality of each mobile station undergo changes. 因此,例如,靠近基站(high geometry)的移动站具有较好的前向和反向链路信道,所以对于授权信号只需较低的功率,并且可能能够利用高数据速率,因此对于单独授权是所期望的。 Thus, for example, close to the base station (high geometry) of the mobile station has good forward and reverse link channel, the grant signal for requiring a lower power, and may be capable of using a high data rate, the individual is authorized for It expected. 远离基站(Iowgeometry)的移动站或者经历较深衰落的移动站,会需要明显较多的功率来可靠地接收单独授权。 From the base station (Iowgeometry) mobile station or a mobile station experiencing deeper fading, may require significantly more power to reliably receive a separate authorization. 这样的移动站可能不是单独授权的最佳候选者。 Such a mobile station may be the best candidate is not a separate authorization. 下面将详细说明,该移动站的公共授权在前向链路开销方面可能不太便宜。 Will be described below in detail, the authorized public mobile station on the forward link may be less expensive cost aspect.

[0088] 在该示例性实施例中,在特定时间采用了多个独立的F-GCH信道来提供相应数量的独立授权。 [0088] In this exemplary embodiment, using a plurality of independent channels of F-GCH at a particular time to provide a corresponding number of separate authorization. F-GCH信道是码分复用的。 F-GCH channels are code division multiplexed. 这样就能够按照刚好到达特定预期移动站所需的功率电平,来发送每个授权。 Thus it is possible to reach the desired power level just the specific intended mobile station according to each transmission authorization. 在另一实施例中,可以采用一个单独的授权信道,对该数量的各种授权进行时间复用。 In another embodiment, the authorization may be used a single channel, the time-multiplexing of various authorization number. 为了在时分复用的单独F-GCH上改变每个授权的功率,可以引入附加的复杂度。 In order to change the power of each authorized individual time division multiplexed on F-GCH, may introduce additional complexity. 在本发明的保护范围内,可以采用任何信令技术来传递公共或单独授权。 Within the scope of the present invention, any public or signaling technique to transmit separate authorization.

[0089] 在有些实施例中,为了在某一时间支持较大数量的单独授权,采用了较大数量的单独授权信道(即F-GCH)。 [0089] In some embodiments, the authorized individual at a certain time in order to support a larger number, using a large number of individual grant channel (i.e. F-GCH). 在这种情况下,最好限制每个移动站要监视的单独授权信道的数量。 In this case the number, it is preferable to limit each mobile station to monitor the grant channel individually. 在一个示例性的实施例中,定义了全部单独授权信道的各子集。 In one exemplary embodiment, each define a subset of all the individual grant channels. 为每个移动站分配一部分单独授权信道来监视。 Each mobile station is allocated a portion of the individual grant channels to monitor. 这使得移动站能够降低处理的复杂度,相应地降低功耗。 This enables the mobile station to reduce processing complexity, and correspondingly reduce power consumption. 折衷在于调度灵活性,因为调度基站可能无法任意地分配单独授权的集合(例如,不能对单个组中的成员做出所有的单独授权,因为这些成员不监视一个或多个单独授权信道)。 Scheduling flexibility tradeoff is that, since the scheduling base station may not be able to arbitrarily assign individual authorization set (e.g., not authorized to make all of the individual members of a single group, since those members do not monitor one or more individual grant channels). 应当注意的是,灵活度的损失未必导致容量的损失。 It should be noted that the loss of flexibility does not necessarily result in loss of capacity. 为了说明,考虑一个包括四个单独授权信道的例子。 To illustrate, consider an example including four individual grant channels of. 可分配编号为偶数的移动站来监视前两个授权信道,可以分配编号为奇数的移动站来监视后两个授权信道。 It may be allocated even-numbered before the mobile station monitors the grant channel two may be assigned the odd numbered mobile station monitors the grant channel two. 在另一例子中,这些子集可以重叠,例如,监视前三个授权信道的偶数移动站和监视后三个授权信道的奇数移动站。 In another example, the subsets may overlap, e.g., even after the mobile station monitors three grant channels, and the front monitor authorized channel three odd mobile stations. 很显然,调度基站不能任意分配来自一个组的四个移动站(偶数或奇数)。 Obviously, the scheduling base station can not arbitrarily assign four mobile stations from one group (even or odd). 这些例子只是说明性的。 These examples are merely illustrative. 在本发明的保护范围内,可以采用具有任何子集配置的任何数量的信道。 Within the scope of the present invention, a channel may be employed with any subset of any number of configurations.

[0090] 用公共授权可以准予已经发出了请求、但尚未收到单独授权的剩余移动站在R-ESCH上进行发送,该公共授权指定剩余每个移动站都必须遵循的最大T/P比。 [0090] The authorization may be granted by the common request has been issued, but have not received a separate authorization residual movement of standing on R-ESCH transmission, the common T specifies the maximum authorized residual each mobile station must follow / P ratio. 公共F-GCH 也可被称为前向公共授权信道(F-CGCH)。 Common F-GCH may also be referred to as a forward common grant channel (F-CGCH). 移动站监视一个或多个单独授权信道(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. 除非给予单独授权,否则,如果发出公共授权,移动站就会发送。 Unless authorized administered alone, or, if you issue a public authorization, the mobile station will be sent. 公共授权表示剩余的移动站(公共授权移动站)可以发送具有特定类型QoS的数据的最大T/P 比。 Public License represents the remaining mobile stations (the common unlicensed mobile station) may send a maximum T / P ratio of the data having a certain type of QoS.

[0091] 在该示例性实施例中,每个公共授权在一定数量的子数据包传输间隔内是有效的。 [0091] In the exemplary embodiment, each common authorization is valid within a sub-packet transmission interval of a certain number. 一旦收到公共授权,发出请求、但尚未得到单独授权的移动站就可以在后续的传输间隔内开始发送一个或多个编码器数据包。 Upon receipt of public authorization request, but has not yet been authorized individual mobile station can begin transmitting the one or more encoder packets within the subsequent transmission intervals. 授权信息可以重复多次。 Authorization information can be repeated many times. 这样,相比单独授权,公共授权是以较低功率电平发送的。 In this way, compared to a separate authorization, authorized public at a lower power level sent. 每个移动站可以组合来自多个传输的能量,以可靠地对公共授权进行解码。 Each mobile station may combine the energy from multiple transmissions to reliably decode the common authorization. 因此,可以为远离基站的移动站选择公共授权,例如,当就前向链路容量而言单独授权被视为太昂贵时。 Thus, the public may choose to authorize the mobile station from the base station, e.g., a single authorization on the current link capacity in terms are deemed too expensive. 但是,公共授权仍需要开销,下面将详细描述用于降低该开销的各种技术。 However, the public still need to authorize spending, will detail the various techniques for reducing this overhead are described.

[0092] 基站将F-GCH发送到每个移动站,基站对其进行调度,以传输新的R-ESCH数据包。 [0092] The F-GCH base station transmits to each mobile station, the base station schedule it, to transmit a new R-ESCH packet. 也可以在编码器数据包的传输或重发期间发送它,从而强迫移动站改变它对于编码器数据包的后续子数据包的传输的T/P比,如果拥塞控制变得必要的话。 It may also be transmitted in the transmission encoder packet or a retransmission during it, thereby forcing the mobile station change the T / P ratio for the transmission of subsequent sub-packet of the encoder packet, if congestion control becomes necessary.

[0093] 在该示例性实施例中,公共授权包括12个比特,其中包括3比特类型字段,用于指明后9个比特的格式。 [0093] In this exemplary embodiment, the common grant comprises 12 bits including a 3-bit type field for indicating the 9-bit format. 剩余的比特表示类型字段中指明的三种移动站的最大容许T/P比, 其中3个比特表示每类的最大容许T/P比。 The remaining bits indicate the type field indicates the maximum allowable three kinds of mobile stations T / P ratio, which represents 3 bits of each class the maximum allowable T / P ratio. 移动站类型可以基于QoS要求或其他标准。 Type mobile station may be based on QoS requirements or other criteria. 也可以采用各种其他公共授权格式,这对于本领域技术人员来说是显而易见的。 It can also be used in various other public Authorized format, which is apparent to those skilled in the art.

[0094] 在该示例性实施例中,一个单独授权包括12个比特,其中包括的11个比特表示移动站ID和被授权发送的移动站的最大容许T/P比,或者,明确地告诉移动站改变其最大容许T/P比,包括将最大容许T/P比设置为O ( S卩,告诉移动站不要发送R-ESCH)。 [0094] In the exemplary embodiment, an individual grant comprises 12 bits, including 11 bits indicates a maximum allowable mobile station ID and the mobile station is authorized to send the T / P ratio, or explicitly tells the mobile station to change its maximum allowed T / P ratio, including the maximum allowable T / P ratio is set to O (S Jie, telling the mobile station not to transmit R-ESCH). 这些比特指明移动站ID (192个值中的一个)和指定移动站的最大容许T/P (10个值中的一个)。 These bits indicate the mobile station ID (a 192 values) and the maximum allowable specified mobile station T / P (a value of 10). 在另一实施例中,对于指定的移动站,可以设置一个长授权比特。 In another embodiment, for a given mobile station, the authorization may be provided a long bit. 当将该长授权比特设为1时, 准许移动站在该ARQ信道上发送较大固定、预定数量(可用信令进行更新)的数据包。 When this bit is set to 1 long authorization, permit the mobile station transmits the ARQ channel large fixed, predetermined number (available update signaling) packets. 如果将该长授权比特设为0,则授权移动站发送一个数据包。 If this bit is set to 0 long authorization, the mobile station is authorized to transmit a packet. 使用零T/P值规范,可以告诉移动站关断它的R-ESCH传输,而这可用于告诉移动站关断它在R-ESCH上的传输,如果该长授权比特是关断,对于单个数据包的单个子数据包传输,如果该长授权比特接通,对于较长时间。 A zero T / P value specification, can tell the mobile station turns off its R-ESCH transmissions, which can be used to tell the mobile station turns off its transmission on the R-ESCH, if the length of the authorization bit is turned off, for a single single sub-packet transmission packet, if the length bit is turned on authorization, for a long time.

[0095] 在一个示例性实施例中,移动站仅仅监视来自服务基站的F-GCH。 [0095] In one exemplary embodiment, the mobile station only monitors the F-GCH from the serving base station. 如果移动站收到一个F-GCH消息,那么,移动站监视该F-GCH消息中的速率信息,并忽略速率控制比特。 If the mobile station receives an F-GCH message, then the mobile station monitors the rate information in the F-GCH message and ignores the rate control bits. 或者,移动站可以使用这样的准则:如果来自服务基站之外的一个基站的任何速率控制指示表示速率降低(即,RATE_DECREASE命令,下面将对此做详细说明),则移动站降低其速率, 即使F-GCH指示增速。 Alternatively, the mobile station may use such criteria: If at any rate from a base station other than the serving base station indicates a rate decrease control instruction (i.e., RATE_DECREASE command, as will be discussed in detail below), the mobile station decrease its rate even if the F-GCH indicates growth. [0096] 在另一实施例中,移动站监视来自所有基站或其活动集合中一部分基站的F-GCH。 [0096] In another embodiment, the mobile station monitors the F-GCH from all base stations in the active set, or a part of a base station. 高层信令通过切换指示消息或其他消息,指示该移动站监视哪些F-GCH以及如何在信道分配时组合它们。 Layer signaling message or other indication message by switching, indicating that the mobile station which F-GCH monitor and how to combine them at channel assignment. 应当注意的是,可以对来自不同基站的一部分F-GCH进行软组合。 It should be noted that the soft combining may be part of F-GCH from different base stations. 将这种可能性告知移动站。 The possibility to inform the mobile station. 在来自不同移动站的F-GCH可能进行了软组合之后,在任何时间,可能还有多个F-GCH。 After the F-GCH from different mobile stations may be soft combination, at any time, there may be a plurality of F-GCH. 移动站可以将其传输速率决定为最低的授权速率(或其他准则)。 The mobile station may be determined as the transmission rate of the lowest rate of authorization (or other criteria).

[0097] R-PICH [0097] R-PICH

[0098] 反向导频信道(R-PICH)从移动站传输到活动集合中的基站。 [0098] reverse pilot channel (R-PICH) transmitted from the mobile station to the base station in the active set. 可以在一个或多个移动站中测量R-PICH的功率,以用于反向链路功率控制。 R-PICH may be measured at the power of the one or more mobile stations for use in reverse link power control. 在本领域所公知的是,导频信号可用于提供在相干解调中使用的幅度和相位测量。 Well it is known in the art that the pilot signal may be used to provide amplitude and phase measurements for use in coherent demodulation. 如上所述,将移动站可用的发射功率量(不管受限于调度基站还是移动站功率放大器的内在限制)在导频信道、业务信道和控制信道之间划分。 As described above, the amount of transmit power available to the mobile station (regardless of the limitations inherent in the scheduling base station is limited by the power amplifier or a mobile station) pilot channel is divided between the service channel and control channel. 对于更高的数据速率和调制格式,需要附加的导频功率。 For higher data rates and modulation formats, it requires additional pilot power. 为了简化R-PICH 用于功率控制以及避免与所需导频功率中的瞬时改变相关联的一些问题,可以分配一个附加的信道,作为补充或辅助导频。 To simplify the R-PICH for power control, and to avoid the instantaneous power required for the pilot to change some of the problems associated with, you may be allocated an additional channel, as a supplement or auxiliary pilot. 尽管导频信号通常是用已知的数据序列来发送的,就如同这里所披露的那样,但是,也可采用承载着信号的信息来产生参考信息,以进行解调。 Although the pilot signal is typically a known data sequence to be transmitted, like that disclosed herein, however, it may also be a signal carrying information to generate the reference information for demodulation. 在一个示例性的实施例中,用R-RICH来携带附加的预期导频功率。 In one exemplary embodiment, with the R-RICH is expected to carry the additional pilot power.

[0099] R-RICH [0099] R-RICH

[0100] 移动站使用反向速率指示信道(R-RICH)来指明反向业务信道R-ESCH上的传输格式。 [0100] the mobile station using a reverse rate indicator channel (R-RICH) to indicate the transmission format on the reverse traffic channel R-ESCH. 该信道也可被称为反向分组数据控制信道(R-PDCCH)。 This channel may also be referred to as a reverse packet data control channel (R-PDCCH).

[0101] 只要移动站发送子数据包时,就会发送R-RICH。 [0101] As long as the mobile station transmits sub-packets will be sent R-RICH. 当移动站在R-ESCH上空闲时,也可以通过零速率指示来发送R-RICH。 When the mobile station over the R-ESCH leisure, indication may be transmitted through a zero rate R-RICH. 零速率R-RICH帧(表明没有传输R-ESCH的R-RICH) 的传输有助于基站检测移动站空闲、维持该移动站的反向链路功率控制和其他功能。 Zero-rate R-RICH frames (indicating that no R-ESCH transmission of the R-RICH) helps the base station detect a transmission mobile station is idle, maintain reverse link power control and other functions of the mobile station.

[0102] R-RICH帧的开始与当前R-ESCH传输的开始是时间对准的。 Start [0102] start of the current R-ESCH transmissions R-RICH frame is time aligned. R-RICH的帧持续时间可能相同于或短于相应R-ESCH传输的持续时间。 The frame duration of R-RICH may be identical to or shorter than the duration time of the corresponding R-ESCH transmission. R-RICH传递并发R-ESCH传输的发送格式,如负载、子数据包ID和ARQ实例序列号(AI_SN)比特和用于差错检测的CRC。 R-RICH concurrent R-ESCH transmission transmission transmission format, such as load, CRC subpacket ID and ARQ sequence numbers instance (AI_SN) bits for error detection. 一个示例性的AI_SN是一个比特,每次在特定ARQ上传输新数据包时翻转,故有时被称为“颜色比特”。 When an exemplary AI_SN is a bit, each transmission of a new packet on a particular ARQ inverted, it is sometimes referred to as a "color bit." 这可用于异步ARQ,其中,在数据包的子数据包传输之间没有固定的时序。 This can be used for the ARQ asynchronously, wherein, between the sub-packet transmission of data packets is not fixed timing. 颜色比特可用于防止接收机将相同ARQ信道上的一个数据包的子数据包与一个相邻数据包的子数据包进行组合。 Color bit may be used to prevent the receiver from a data packet to the same ARQ channel with the subpacket of a packet the sub-packets are combined adjacent. R-RICH也可以承载附加的信息。 R-RICH may also carry additional information.

[0103] R-ESCH [0103] R-ESCH

[0104] 在这里描述的示例性实施例中,增强反向补充信道(R-ESCH)用作反向链路业务数据信道。 [0104] In the exemplary embodiments described herein, the reinforcing Reverse Supplemental Channel (R-ESCH) is used as the reverse link traffic data channel. R-ESCH可采用任何数量的传输速率和调制格式。 R-ESCH using any number of transmission rates and modulation formats. 在一个示例性的实施例中, R-ESCH具有以下属性:支持物理层重传。 In one exemplary embodiment, R-ESCH has the following properties: Physical layer retransmissions support. 对于当第一代码是速率1/4代码时的重传,这些重传使用速率1/4代码,且使用能量组合。 When the code for the first retransmission when a rate 1/4 code using these retransmission rate 1/4 code and energy used in combination. 对于第一代码是大于1/4的速率的重传,使用增量冗余。 For the first retransmission the code rate greater than 1/4, incremental redundancy is used. 下面的代码是速率1/5代码。 The following code is a rate 1/5 code. 当然,增量冗余也可用于所有这些情形。 Of course, incremental redundancy may be used for all of these cases.

[0105] 对于可以访问R-ESCH的自动和调度用户二者,都支持混合自动重传请求(HARQ)。 [0105] For both the user can access and automatic scheduling of the R-ESCH, supports hybrid automatic repeat request (HARQ).

[0106] 利用重传之间固定时间,可以支持多个ARQ信道同步操作:允许在相同数据包的连续子数据包之间有固定数量的子数据包。 [0106] using a fixed time between retransmissions, ARQ can support multiple synchronization channels: to allow a fixed number of sub-packets between consecutive sub-packets of the same packet. 当然,也允许交错式传输。 Of course, also allows interlaced transmission. 例如,对于5ms帧, 使用在子数据包之间的三个子数据包延迟,可以支持4信道ARQ。 For example, for 5ms frames, in three sub-packets between the sub-packet delay, the channel may support four ARQ.

[0107] 表1列出了增强反向补充信道的示例性数据速率。 [0107] Table 1 lists the reverse enhanced supplemental channel exemplary data rates. 其中描述了一个5ms的子数据包大小,并且,伴随的信道适合该选择。 Which describes a 5ms sub-packet size, and, along with the selection of the appropriate channel. 也可以选择其他子数据包尺寸,对于本领域技术人员来说这是显而易见的。 Can also select other sub-data packet size, the skilled artisan would be apparent. 对于这些信道,不调整导频参考电平,即,移动站可以灵活地选择T/P,从而把给定操作点作为目标。 For these channels, do not adjust the pilot reference level, i.e., the mobile station may flexibly select T / P, so that the operating point of a given target. 该最大T/P值通过前向授权信道发送。 The maximum T / P value is sent to the front by the grant channel. 如果移动站耗尽了发射功率,则可以使用较低的T/P,从而使HARQ满足所需的QoS。 If the mobile station transmission power runs out, you can use a lower T / P, so that the HARQ meet the required QoS. 第三层信令消息也可以通过R-ESCH传输,这使得系统可以在没有R-FCH和/或R-DCCH的情况下工作。 The third layer signaling messages may also be transmitted through the R-ESCH, which makes the system can operate without the R-FCH and / or s R-DCCH case.

[0111] 在一个示例性的实施例中,对于所有速率,都使用turbo编码。 [0111] In one exemplary embodiment, for all rates, turbo coding use. 对于R= 1/4编码, 使用与当前cdma2000反向链路相类似的交织器。 For R = 1/4 coding, using a similar current cdma2000 reverse link interleaver. 对于R = 1/5编码,使用与cdma2000前向分组数据信道相类似的交织器。 For R = 1/5 coding, before using cdma2000 interleaver similar to the packet data channel.

[0112] 每个编码器数据包的比特数量包括CRC比特和6个尾部比特。 [0112] The number of bits per encoder packet includes the CRC bits and 6 tail bits. 对于编码器数据包大小为192比特,使用12比特的CRC ;否则,使用16比特的CRC0假设5-ms时隙的间隔为15ms,从而有时问做出ACK/NAK响应。 For an encoder packet size of 192 bits, the CRC bits 12 used; otherwise, use a 16-bit interval is assumed CRC0 5-ms slots are 15ms, so sometimes asked to make ACK / NAK response. 如果收到ACK,则不发送剩余时隙的数据包。 If the received ACK, the remaining slots of the packet are not transmitted.

[0113] 上面描述的5ms子数据包持续时间及其关联参数只是作为例子。 [0113] 5ms subpacket duration, and associated parameters described above by way of example only. 通过阅读这里公开的内容,速率、格式、子数据包重复选项、子数据包持续时间等的任意数量的组合对于本领域技术人员都是显而易见的。 A reading of the disclosure herein, rates, formats, subpacket repetition options, a combination of any number of sub-packets for the duration of the person skilled in the art are apparent. 可以采用另一IOms实施例,其使用3个ARQ信道。 IOms another embodiment may be employed, using 3 ARQ channels. 在一个实施例中,选择单个子数据包持续时间或帧尺寸。 In one embodiment, selecting a single subpacket duration or frame size. 例如,可以选择5ms或IOms结构。 For example, 5ms or IOms structure may be selected. 在其他实施例中,系统可以支持多帧持续时间。 In other embodiments, the system may support multiple frame durations.

[0114] F-CPCCH [0114] F-CPCCH

[0115] 当不存在F-FCH和F-DCCH时,或者,当F-FCH和F-DCCH存在但却不专用于一个用户时,可使用前向公共功率控制信道(F-CPCCH)对包括R-ESCH在内的各种反向链路信道进行功率控制。 [0115] When there is no F-FCH and F-DCCH, or, when the F-FCH and F-DCCH is present but not dedicated to a user, prior to use common power control channel (F-CPCCH) including R-ESCH, including the various reverse link channel power control. 信道分配后,为移动站分配了一个反向链路功率控制信道。 After the channel assignment, the mobile station is assigned a reverse link power control channel. F-CPCCH可以包含多个功率控制子信道。 F-CPCCH may contain a plurality of power control subchannels.

[0116] F-CPCCH可以承载被称为公共拥塞控制子信道(F-OLCH)的功率控制子信道。 [0116] F-CPCCH may carry a power control subchannel is called a common congestion (F-OLCH) control subchannel. 示例性的拥塞控制子信道的速率通常为100bps,但也可以采用其他速率。 Exemplary rate congestion control subchannel is typically 100bps, other rates may also be employed. 单个比特(为了可靠性,可以重复),在这里被称为繁忙比特(busy bit),指示处于自动传输模式或公共授权模式或同时处于这两种模式的移动站增加或降低它们的速率。 A single bit (for reliability, can be repeated), referred to herein as the busy bit (busy bit), indicating a transmission mode or in automatic mode or while in a public license increase or decrease their rates of these two modes of the mobile station. 在另一实施例中,单独的授权模式对该比特也很敏感。 In another embodiment, a separate authorization is also very sensitive to the mode bits. 可以采用具有传输类型的任意组合的各种实施例,以响应F-0LCH。 It may be employed with any combination of various types of transmission of the embodiment, in response to the F-0LCH. 这可以概率性地或确定性地完成。 This can be done probabilistically or deterministically.

[0117] 在一个实施例中,将繁忙比特设为“0”表示对繁忙比特做出响应的移动站应当降低它们的传输速率。 [0117] In one embodiment, the busy bit is set to "0" indicates that the mobile station made a response to the busy bit should decrease their transmission rate. 将繁忙比特设为“1”表示传输速率的相应增加。 The busy bit is set to "1" indicates that the corresponding increase in transmission rate. 也可以采用多种其他信令机制,对于本领域技术人员来说这是显而易见的,下面详细描述各种其他例子。 May be using a variety of other signaling mechanisms, the skilled person it will be apparent that various other examples described in detail below.

[0118] 在信道分配期间,将移动站分配给这些专用功率控制信道。 [0118] During channel assignment, the mobile station will be assigned to these special power control channels. 一个功率控制信道可以控制系统中的所有移动站,或者,一个或多个控制信道可以控制移动站的变化子集。 A power control channel may control all mobile stations in the system, or, one or more control channels may be controlled to change the subset of the mobile station. 应当注意的是,该特定信道用于拥塞控制只是一个例子。 It should be noted that the particular channel for congestion control is just one example.

[0119] F-ACKCH [0119] F-ACKCH

[0120] 前向确认信道,即F-ACKCH,由基站用来确认R-ESCH的正确接收,也可用于扩展现有的授权。 [0120] The forward acknowledgment channel, i.e., F-ACKCH, the base station to confirm the correct reception of the R-ESCH, can also be used to extend an existing grant. F-ACKCH上的确认(ACK)表示子数据包的正确接收。 Acknowledgment (ACK) on the F-ACKCH indicates correct reception of a subpacket. 移动站再传输该子数据包是不必要的。 The mobile station re-transmitting the sub-packets is unnecessary. F-ACKCH上的否认(NAK)使移动站发送另一子数据包,这由每个数据包的最大容许数量的子数据包限制。 Denying (NAK) on the F-ACKCH mobile station transmits another sub-packet, the maximum allowable number of packets which each data subpacket limits.

[0121] 在这里详细描述的实施例中,F-ACKCH用于提供接收子数据包的肯定性或否定性确认,以及指示是否要发布速率控制命令(下面将结合F-RCCH信道进行描述)。 [0121] Example embodiments described in detail herein, F-ACKCH is used to provide sub-packet receiving a positive or negative acknowledgment, and rate control data indicating whether a release command (in conjunction with the following F-RCCH channel will be described).

[0122] 图5中的示例性实施例给出了一个三值的F-ACKCH。 [0122] exemplary embodiment of FIG. 5 shows a three-valued F-ACKCH is. 该示例性F-ACKCH包括从一个或多个基站传输到一个移动站的单个指示,其表示从移动站通过R-ESCH的传输是否已被相应的基站正确接收。 The exemplary F-ACKCH includes transmitting from a single or more base stations to indicate a mobile station, which indicates whether to transmit the R-ESCH has been correctly received corresponding base station from the mobile station through. 在一个示例性实施例中,由活动集合中的每个基站发送F-ACKCH 指示。 In one exemplary embodiment, the F-ACKCH transmission indicated by each base station in the active set. 或者,F-ACKCH可由活动集合中的指定子集发送。 Alternatively, F-ACKCH may specify a subset of the active set is transmitted. 发送该F-ACKCH的基站集合可被称为F-ACKCH活动集合。 Transmitting the F-ACKCH may be referred to as a base station set of F-ACKCH Active Set. F-ACKCH活动集合可由第三层(L3)信令通知给移动站,并且可以在信道分配期间在切换指示消息(HDM)中或经由本领域公知的其他技术指定。 F-ACKCH Active Set may be a third layer (L3) signaling to the mobile station, and may be in the handover indication message during the channel assignment (a HDM), or via other techniques designated known in the art.

[0123] 例如,F-ACKCH可以是三状态信道,其具有以下值:NAK、ACK_RC和ACK_ST0P。 [0123] For example, F-ACKCH may be a three-state channel with the following values: NAK, ACK_RC, and ACK_ST0P. NAK 表示来自移动站的数据包必须重传(但是,如果已经发送了最后一个子数据包,则移动站需要使用任何可用技术,如请求/授权、速率控制或自动传输,重发该数据包)。 NAK indicates that the packet from the mobile station to be retransmitted (however, if has sent the last subpacket, the mobile station need to use any available technique, such as request / authorization, rate control or automatic transmission, retransmission of the data packet) . 如果NAK对应于一个数据包的最后一个子数据包,则移动站需要监视相应F-RCCH(下面详细说明)上的速率控制指示。 NAK if a packet corresponding to the last subpacket, the mobile station needs to monitor the corresponding F-RCCH (detailed below) on the rate control instruction.

[0124] ACK_RC表示:来自移动站的数据包不必重传,并且,移动站应当监视相应F-RCCH 上的速率控制指示。 [0124] ACK_RC indicates: the packet from the mobile station need not retransmit, and the mobile station should monitor the Rate on F-RCCH corresponding control instruction. ACK_ST0P也表示不必重传。 ACK_ST0P also said that does not have to be retransmitted. 但在这种情况下,对于下一次传输,移动站应当回到自动模式,除非移动站通过F-GCH(上面已做了详细说明)接收到授权消息。 However, in this case, for the next transmission, the mobile station shall return to the automatic mode, unless the mobile station through the F-GCH (detailed description above has been done) receipt of the authorization message.

[0125] L3信令可以指示移动站是否对来自其活动集合中不同基站的F-ACKCH指示进行软组合。 [0125] L3 signaling may indicate whether the mobile station from the active set of its F-ACKCH indicates different base stations for soft combining. 这等同于根据IS-2000版本C处理功率控制比特。 This is equivalent to the control bits in accordance with IS-2000 Revision C of processing power. 例如,可能有一个指示,比方说ACK_C0MB_IND,它是在信道分配之后发送的且在切换消息中,其表示移动站是否对来自不同基站的F-ACKCH指示进行组合。 For example, there may be an indicator, say ACK_C0MB_IND, which is transmitted after the handover and channel allocation message which indicates whether the mobile station on F-ACKCH from different base stations are combined indication. 可采用多种技术来发送F-ACKCH,它们的例子如下所述。 A variety of techniques may be employed to transmit the F-ACKCH, examples of which are described below. 有些例子包括独立的TDM信道、TDM/CDM信道或其他格式。 Some examples include a separate TDM channel, TDM / CDM channels, or other formats.

[0126] 在该示例中,有两种类型的结果来自监视F-ACK信道,这取决于数据包是否被确认。 [0126] In this example, there are two types of results from the monitoring F-ACK channels, depending on whether the data packet was acknowledged. 如果收到NAK,则有多种选项。 If you receive a NAK, you have several options. 移动站可以发送另外的子数据包,直到发送了最大数量的子数据包为止(在该示例性实施例中,子数据包是用相同传输格式发送的,不管是通过自发传输还是授权传输启动的,也不管是否有速率控制改变。在其他实施例中,使用这里公开的任何技术,可以改变子数据包传输格式)。 The mobile station may send additional subpackets until the transmission of the maximum number of sub-packets up to (in this exemplary embodiment, the subpackets are sent using the same transmission format, whether or authorization spontaneously transmitted over a transmission start , regardless of whether a change rate control. in other embodiments, using any of the techniques disclosed herein may be changed subpacket transmission format). 在最终子数据包的NAK之后,移动站可以采取与相应速率控制命令有关(监视F-RCCH)的行动,根据前一授权或速率控制命令停止发送(即,如果希望的话,回到自动传输),或者对新接收的授权做出响应。 After the NAK final subpacket, the mobile station can take action corresponding to a rate control command related to (monitors F-RCCH), the control command according to the previous grant or rate ceases transmission (i.e., if desired, back to the automatic transmission) or respond to newly received authorization.

[0127] 如果收到ACK,它可能对应于速率控制命令或停止指示。 [0127] If the received ACK, which may correspond to a rate control command or an indication to stop. 如果表示速率控制,则监视和跟踪速率控制信道(F-RCCH)。 If represents the rate control, monitoring and tracking the rate control channel (F-RCCH). 如果结果是停止,则移动站不跟踪F-RCCH上的速率控制指示,而是回到自动模式(以所分配的最大自动速率发送)。 If the outcome is to stop, then the mobile station does not follow the rate control on the F-RCCH indicated, but return to the automatic mode (automatic transmission at the maximum rate allocated). 如果在ACK_ST0P同时接收到显式授权,则移动站服从该显式授权中的命令。 If the received explicit authorization ACK_ST0P while, the mobile explicit authorization station to obey commands.

[0128] 例如,首先考虑单个活动集合成员或来自所有扇区的指示相同的情况(也是由ACK_C0MB_M表示的)。 [0128] For example, first consider a single Active Set member or from the same cases indicates that all sectors (also indicated by the ACK_C0MB_M). 在这种情况下,有单个指示。 In this case, a single indication. 当移动站收到NAK(未传输的指示),那么,移动站重传下一子数据包(在合适的时间)。 When the mobile station receives NAK (non-transmission indication), then the mobile station retransmits the next subpacket (at the appropriate time). 如果移动站没有收到最后一个子数据包的ACK,则移动站继续下一数据包(可以根据所采用的重传算法,重传出错的数据包)。 If the mobile station does not receive ACK last sub-packet, the mobile station continues to the next packet (according to the retransmission algorithm can be used, to retransmit the data packet error). 但是, 移动站将此作为速率控制指示(即,监视速率控制信道)。 However, the mobile station this as a rate control indication (i.e. monitors the rate control channel).

[0129] 在该示例中,一般准则如下(适用于单个活动集合成员和多个不同F-ACKCH活动集合成员)。 [0129] In this example, the following general guidelines (for single active set member and a plurality of different members of the active set of F-ACKCH). 如果某个指示是ACK_ST0P或ACK_RC,则结果是ACK。 If an indication is ACK_ST0P or ACK_RC, the result is ACK. 如果没有指示是ACK_ STOP或ACK_RC,则结果是NAK。 If no indication is ACK_ STOP or ACK_RC, the result is a NAK. 所以,对于速率控制,如果某个指示是ACK_ST0P,移动站将停止(即,回到自动模式,或对授权做出响应,如果有的话)。 Therefore, for rate control, if an indication is ACK_ST0P, the mobile station will stop (i.e., return to the automatic mode, or respond to the authorization, if any). 如果没有指示是ACK_ST0P且至少一个指示是ACK_RC,则对相应基站的速率控制信道(F-RCCH)上的指示进行解码。 If no indication is ACK_ST0P and at least one indication is ACK_RC, the rate of the corresponding base station on the control channel indicative (F-RCCH) is decoded. 如果已经发送了最后一个子数据包且所有指示都是NAK,则对所有基站的速率控制信道(F-RCCH) 上的指示进行解码。 If a child has transmitted the last data packet and all instructions are NAK, the base stations for all rate control channel (F-RCCH) decoding instructions. 下面结合F-RCCH详细描述如何在这些情况下对速率控制命令做出响应。 F-RCCH The following detailed description in conjunction with how to respond to the rate control commands in these cases. [0130] 与速率控制信道组合起来的ACK_RC命令可被视为一种类型的命令,其被称为ACK-and-Continue命令。 [0130] combining the rate control channel ACK_RC commands may be considered a type of command, it referred to as ACK-and-Continue commands. 移动站根据可发出的各种速率控制命令(下面详细描述示例),可以继续发送后续的数据包。 The mobile station according to the control command may be issued at various rates (examples detailed below), may continue to transmit subsequent data packets. ACK-and-Continue命令使得基站能够确认数据包的成功接收, 与此同时,移动站使用导致成功接收数据包的授权(根据速率控制命令,可能有改变)来发送。 ACK-and-Continue command enables the base station to acknowledge successful reception of a data packet, at the same time, cause the mobile station to use authorization successfully received packet (according to the rate control command, there may be change) to transmit. 这节约了新授权的开销。 This saves the cost of a new authorization.

[0131] 在图5所示的F-ACKCH的实施例中,ACK_ST0P符号使用正值,NAK使用NULL符号, ACK_RC符号使用负值。 [0131] In an embodiment of the F-ACKCH shown in FIG. 5, ACK_ST0P value symbols, NAK using the NULL symbol, ACK_RC negative symbols. F-ACKCH上的开关键控(S卩,不发送NAK)使得基站(尤其是非调度基站)能够不发送ACK,当如此做的成本(所需的功率)太高时。 Off Keying (S Jie, do not send NAK) on the F-ACKCH that the base stations (especially non-scheduling base stations) are not able to transmit the ACK, the cost of doing so when the (desired power) is too high. 这样,基站就可以在前向链路和反向链路容量之间取得折衷,因为未被确认的正确接收数据包可能会在后面的时间点触发重传。 Thus, the base station may trade off between the forward link and reverse link capacity, since a correctly received unacknowledged packets may trigger the retransmission at a later point of time.

[0132] 在本发明的保护范围内,可以采用各种发送F-ACKCH的技术。 [0132] within the scope of the present invention, the F-ACKCH transmit various techniques can be employed. 可将各移动站的单独信号组合在公共信道中。 Signal combining separate each mobile station may be in a common channel. 例如,多个移动站的确认响应可以进行时间复用。 For example, the plurality of acknowledgment response from the mobile station may be time multiplexed. 在一个示例性的实施例中,在一个F-ACKCH上最多可以支持96个移动站ID。 In one exemplary embodiment, it can support up to 96 mobile station ID on one F-ACKCH. 为了支持另外的移动站ID,可以采用附加的F-ACKCH。 In order to support additional mobile station ID, you can use the additional F-ACKCH.

[0133] 另一个例子是将多个移动站的多个确认信号映射到一组正交函数上。 [0133] Another example is to map a plurality of acknowledgment signals from a plurality of mobile stations onto a set of orthogonal functions. Hadamard编码器是一种用于映射到一组正交函数上的编码器。 Hadamard Encoder is an encoder for mapping to a set of orthogonal functions. 也可以采用其他多种技术。 A variety of other techniques may also be employed. 例如,可以使用Walsh码或其他类似纠错码,对信息比特进行编码。 For example, a Walsh code or other similar error correcting code, the information bits are encoded. 如果每个独立的子信道具有独立的信道增益,则可以按照不同的功率电平传输到用户。 If each individual subchannel has an independent channel gain, the user may be in a different transmission power levels. 示例性的F-ACKCH为每个用户传递一个专用的三值标志。 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合中所有基站的F-ACKCH (或者,信令可以定义较小的活动集合,以降低复杂度)。 Each user monitors the F-ACKCH from all base stations in its active set (or, signaling may define a smaller set of activities, in order to reduce complexity).

[0134] 在各种实施例中,两个信道各由一个128码片的Walsh覆盖序列覆盖。 [0134] In embodiments, two channels are each covered by a 128-chip Walsh cover sequence in the various embodiments. 一个信道在I信道上传输,另一信道在Q信道上传输。 A channel I transmitted over a channel, in another channel transmission over a channel Q. F-ACKCH的另一实施例使用单个128码片的Walsh覆盖序列,以同时最多支持192个移动站。 Another Walsh Example F-ACKCH uses a single 128-chip cover sequence to support up to 192 mobile stations. 对于每个三值标志,一个示例性的实施例使用10-ms的持续时间。 For each of the three flag values, an exemplary embodiment using the exemplary embodiment of the 10-ms duration.

[0135] 回顾一下,当移动站有一个需要使用R-ESCH来发送的数据包时,它可以在R-REQCH上请求。 [0135] To review, when the mobile station has a need to transmit data using the R-ESCH packet, it may request on the R-REQCH. 基站可以使用F-GCH,用一个授权做出响应。 The base station may use the F-GCH, responds with a grant. 但是,该操作可能是比较昂贵的。 However, this operation may be relatively expensive. 为了降低前向链路开销,F-ACKCH可以发送ACK_RC标志,它通过调度基站(或其他, 当支持来自多个基站的软切换授权时)以低成本地扩展现有的授权(要进行速率控制)。 In order to reduce the front, F-ACKCH may send the ACK_RC flag to the link cost, which scheduling base station (or others, when soft handover is supported authorization from multiple base stations) to extend the existing authorization low cost (to be rate controlling ). 该方法适用于单独和公共授权。 This method is applicable to common and individual authorization. 使用来自授权基站的ACK_RC,扩展相同ARQ信道(要进行速率控制)上另一编码器数据包的当前授权。 Use ACK_RC authorization from the base station, extending the same ARQ channel (to be rate controlling) the current authorization further encoder packet.

[0136] 应当注意的是,如图4所示,并非活动集合中的每个基站都需要回送F-ACKCH。 [0136] It should be noted that, as shown, not in the active set for each base station 4 needs loopback F-ACKCH. 在软切换状态下发送F-ACKCH的基站的集合可能是活动集合的一个子集。 F-ACKCH transmission of a base station in the soft handover set may be a subset of the active set. 2003年6月30日提交的、题目为“C0DEDIVISI0N MULTIPLEXING COMMANDS ON A CODE DIVISIONMULTIPLEXED CHANNEL”的公共待决美国专利申请No. 10/611,333中描述了发送F-ACKCH的示例性技术, 该申请已转让给本发明的受让人。 June 30, 2003, filed, entitled "C0DEDIVISI0N MULTIPLEXING COMMANDS ON A CODE DIVISIONMULTIPLEXED CHANNEL" public pending US Patent Application No. 10 / 611,333 describes an exemplary technique to send F-ACKCH, and the application has been assigned to the assignee of the present invention.

[0137] F-RCCH [0137] F-RCCH

[0138] 前向速率控制信道(F-RCCH)从一个或多个基站传输到一个移动站,以通知下一次传输的速率调整。 [0138] before the rate control channel (F-RCCH) is transmitted from one or more base stations to a mobile station, a transmission rate notified next adjustment. 可以分配一个移动站,来监视来自F-ACKCH活动集合或其一个子集中的每个成员的指示。 A mobile station may be allocated to each member of the monitoring instruction from the F-ACKCH Active Set or a subset. 为清楚起见,由移动站监视的、发送F-RCCH的基站集合被称为F-RCCH活动集合。 For clarity, the mobile station monitors, and transmits the F-RCCH set of base stations is referred to as F-RCCH Active Set. F-RCCH活动集合可由第三层(L3)信令来通知,这可以在信道分配期间在切换指示消息(HDM)中或采用本领域技术人员公知的各种其他方式来指明。 F-RCCH Active Set may be a third layer (L3) signaling to inform, it can handover indication message during the channel assignment (a HDM), or using techniques well known to those skilled in various other ways indicated.

[0139] 图6示出了一个示例性的F-RCCH。 [0139] FIG. 6 illustrates an exemplary F-RCCH. 该F-RCCH是三态信道,具有以下值:RATE_ HOLD,表示移动站可以按照与当前数据包相同的速率,发送下一数据包;RATE_INCREASE,表示移动站可以确定性地或概率性地相对于当前数据包的传输速率提高最高速率,以发送下一数据包;RATE_DECREASE,表示移动站可以确定性地或概率性地相对于当前数据包的传输速率降低最高速率,以发送下一数据包。 The F-RCCH is a three-state channel with the following values: RATE_ HOLD, indicates that the mobile station can follow the same rate of current packet, transmit the next packet; RATE_INCREASE, the mobile station may represent stochastic or deterministic manner with respect to the current transmission rate of data packets to increase the maximum rate to transmit the next data packet; RATE_DECREASE, the mobile station may represent stochastic or deterministic manner with respect to the current transmission rate of data packets reduce the maximum rate to transmit the next packet.

[0140] L3信令可以表示移动站是否要将来自不同基站的速率控制指示进行组合。 [0140] L3 signaling may indicate whether the mobile station from different base stations want to control the rate indication may be combined. 这类似于IS-2000Rev. C中使用功率控制所做的事情。 This is similar to IS-2000Rev. C used in the power control does things. 因此,存在一个指示,例如RATE_C0MB_IND, 其在信道分配时发送且在切换消息中,表示移动站是否要对来自不同基站的F-RCCH比特进行软组合。 Thus, there is an indication, e.g. RATE_C0MB_IND, its transmission when the handover and channel allocation message, for indicating whether the mobile station is to F-RCCH bits from different base stations are soft combined. 本领域技术人员应当理解,发送诸如F-RCCH之类的信道的格式很多,包括独立TDM信道、组合的TDM/CDM信道或其他格式。 It should be understood by those skilled in the art, such as many transmission channel format like the F-RCCH, including separate TDM channels, combined TDM / CDM channels, or other formats.

[0141] 在不同的实施例中,可以采用不同的速率控制配置。 [0141] In various embodiments, the rate control may use different configuration. 例如,所有移动站可由每个扇区的单个指示控制。 For example, all mobile stations controlled by a single indication for each sector. 或者,每个移动站可由每个扇区的专用于每个移动站的不同指示控制。 Alternatively, each mobile station may be dedicated to a different control for each sector is indicative of each mobile station. 或者,多组移动站可由它们自己的分配指示控制。 Alternatively, multiple mobile stations may be assigned their own instruction control. 采用这样的配置,具有相同最大QoS等级的移动站分配得到相同的指示。 With such a configuration, with the same maximum QoS grade to obtain the same mobile station allocation indication. 例如,一个已分配的指示可以控制那些唯一流被指定为“尽最大努力”的所有移动站,从而降低这些最大努力流的负载。 For example, indicating a possible control those assigned a unique stream is designated "best effort" of all mobile stations, thereby reducing the load of these best effort streams.

[0142] 此外,可用信令来配置一个移动站,从而使该移动站只关注来自服务基站或来自F-RCCH活动集合中所有基站的F-RCCH指示。 [0142] Further, signaling can be used to configure a mobile station so that the mobile station only concern a set of F-RCCH indication from the serving base station or from the F-RCCH activity in all base stations. 应当注意的是,如果该移动站只监视来自服务基站的指示,并且,RATE_C0MB_IND指明该指示与来自多个基站的相同,那么,移动站对与服务基站相同组中的所有指示进行组合,然后做出决策。 It should be noted that, if the mobile station only monitors the instruction from the serving base station, and, RATE_C0MB_IND the indication indicates the same from multiple base stations, then indicate to all mobile stations in the same group are combined serving base station, then do the decision-making. 这组在任何时间使用不同速率控制指示的基站集合将被称为F-RCCH当前集合。 This set of base stations using different set of rate control instruction at any time will be referred to the current set of F-RCCH. 因此,如果配置移动站,使其只关注来自服务基站的F-RCCH指示,那么,F-RCCH当前集合的尺寸是1。 Therefore, if the configuration of the mobile station, so that it only concerns F-RCCH indication from the serving base station, then the size of the F-RCCH is a current collection.

[0143] 应当想象到的是,F-RCCH的使用规则可由基站进行调整。 [0143] It is conceivable, F-RCCH may be adjusted using the rule base. 下面是一组示例性的规则,用于具有单成员F-RCCH当前集合的移动站。 The following is an exemplary set of rules for a mobile station having a single-member F-RCCH Current collection. 如果收到RATE_H0LD,则移动站不改变其速率。 If you receive RATE_H0LD, the mobile station does not change its rate. 如果收到RATE_INCREASE,则移动站将其速率加1 (即,一个速率等级,上面的表1对其示例做了详细说明)。 If you receive a RATE_INCREASE, then the mobile station will increase its rate 1 (i.e. one rate level, examples of the above Table 1, a detailed description thereof). 如果收到RATE_DECREASE,则移动站将其速率减1。 If you receive a RATE_DECREASE, the mobile station will decrease its rate of 1. 应当注意的是,只有环境规定时(即ACK处理所导致的行动表示速率控制是活动的,下面将做详细描述),移动站才监视这些指示。 It should be noted that only a predetermined environment (i.e., ACK processing operation indicates the rate control caused is active, as will be described in detail), the mobile station monitors these indicators only.

[0144] 下面的一组规则用于具有多个F-RCCH当前集合成员的移动站。 [0144] The following set of rules for a mobile station having a plurality of F-RCCH current set members. 修改将速率增加/减少1个速率的简单规则。 Modify the increase / decrease rate of a simple rule rate. 如果收到ACK_ST0P,则移动站回到自动速率。 If you receive ACK_ST0P, the mobile station back to the automatic rate. 否则,如果指示为RATE_DECREASE,则移动站将其速率减1。 Otherwise, if the indication is a RATE_DECREASE, the mobile station will decrease its rate of 1. 如果没有指示为RATE_DECREASE并且至少一个基站有一个表示RATE_H0LD的速率控制动作(由ACK处理所导致),那么,移动站维持相同的速率。 If no indication is RATE_DECREASE and at least one base station has a rate control operation represented RATE_H0LD (caused by the ACK process), then the mobile station maintains the same rate. 如果没有指示为RATE_DECREASE、没有基站指示速率控制和RATE_H0LD并且至少一个基站有速率控制动作和RATE_INCREASE指示,则移动站将其速率加1。 If no indication is RATE_DECREASE, no base station indicates rate control and RATE_H0LD and at least one base station has a rate control operation and RATE_INCREASE indication, the mobile station will increase its rate 1.

[0145] 将授权、ARQ和速率控制命令进行组合的实施例 [0145] The authorization, ARQ and rate control commands embodiment of a combination

[0146] 将上述方面总结一下,可以授权移动站执行自动传输,其吞吐量可能是有限的,但却能实现低延迟。 [0146] To summarize the above aspect, the mobile station may authorize the automatic transmission, throughput may be limited, but it can achieve low latency. 在这种情况下,移动站可以在不请求的情况下发送,最多达到最大R-ESCH T/P比T/Pmax—aut。 In this case, the mobile station may transmit without request up to the maximum R-ESCH T / P ratio T / Pmax-aut. ,它可由基站通过信令进行设置和调整。 , Which may be set and adjusted by the base station signaling. [0147] 在一个或多个调度基站中可以确定调度,并且,可以通过在F-GCH上以较高速率传输的授权来分配反向链路容量。 [0147] Scheduling may be determined at one or more scheduling base stations, and can be distributed by authorized reverse link capacity transmission at a higher rate on the F-GCH. 此外,可使用速率控制命令来修改前面授权的传输或自动传输,开销很低,从而调节反向链路容量的分配。 Additionally, rate control commands may be used to modify the previous transmission or automatic transmission authorization, low overhead, thereby adjusting the distribution of reverse link capacity. 因此,可以通过调度来严格地控制反向链路负载,从而保护话音质量(R-FCH)、DV反馈(R-CQICH)和DV确认(R-ACKCH)。 Thus, it is possible to strictly control the reverse link load scheduling, to protect voice quality (R-FCH), DV feedback (R-CQICH) and DV acknowledgment (R-ACKCH).

[0148] 单独授权能够对移动站的传输实现细节化的控制。 [0148] separate authorization possible detailed control the transmission of the mobile station. 移动站的选择可以基于其相对于基站的距离和QoS,从而提高吞吐量,同时维持所需的服务等级。 The mobile station may be selected based on their distance with respect to the base station and QoS, thereby improving the throughput while maintaining required service levels. 公共授权能够实现高效的通知,尤其对于远离基站的移动站。 Public License enables efficient notification, especially for a mobile station from the base station.

[0149] F-ACKCH信道与F-RCCH信道的组合能够有效地实现“ACK-and-Continue”命令, 从而以很低的成本扩展现有的授权。 [0149] F-ACKCH channel in combination with the F-RCCH channel to effectively implement the "ACK-and-Continue" commands, which extend existing at a low cost authorization. (继续可由速率控制,如上所述,下面还将详细说明)。 (Rate control may be continued, as described above, will be described in detail below). 这适用于单独授权和公共授权。 This applies to single authorization and Public License. 在共享资源上,如IxEV-DV反向链路上,调度、授权和发送的各种实施例和技术在2003年8月21提交的、题为“SCHEDULED AND AUTONOMOUS TRANSMISSION ANDACKNOffLEDGEMENT"的公共待决美国专利申请No. 10/646, 955 中做了描述,该申请已转让给本发明的受让人,故以引用方式并入此处。 On shared resources, such as the IxEV-DV reverse link, scheduling, authorization and send the cases and the implementation of various technologies presented at the August 21, 2003, entitled "SCHEDULED AND AUTONOMOUS TRANSMISSION ANDACKNOffLEDGEMENT" public pending United States Patent application No. 10/646, 955 are been described, which application is assigned to the assignee of the present invention, it is incorporated by reference herein.

[0150] 图7示出了示例性方法700,一个或多个基站可采用它来分配容量,以响应来自一个或多个移动站的请求和传输。 [0150] FIG. 7 illustrates an exemplary method 700, it may employ one or more base stations to allocate capacity in response from one or more mobile stations and the transmission requests. 要注意的是,图中所示模块的次序只是一个例子,在不偏离本发明保护范围的前提下,各种模块的次序可以互换,或者与未显示的其他模块结合起来。 It is noted that the order of the module shown in FIG merely an example, without departing from the scope of the present invention, the order of the various modules can be interchanged or combined with other modules not shown. 处理开始于框710。 The process begins at block 710. 基站收到可能是由一个或多个移动站发送的传输请求。 The base station receives a transmission request may be transmitted by one or more mobile stations. 方法700可以无限地重复执行,所以,也可能接收到先前可能还未被授权的请求,这些请求可以与新的请求组合起来,以根据请求估计传输需求量。 The method 700 may be repeated indefinitely performed, it is also possible to previously may not have been received authorization requests, which may be combined with new requests to estimate the transmission request according to demand.

[0151] 在框720中,一个或多个移动站可以发送子数据包以便由基站接收。 [0151] In block 720, one or more mobile stations may transmit subpackets to be received by the base station. 发送的这些子数据包可能已经根据先前授权(潜在地用先前的速率控制命令修改)或自动地(也是潜在地用先前的速率控制命令修改)发送。 These transmitted subpackets may have been transmitted or automatically (also potentially modified with previous control command rate) according to the previous authorization (potentially with previous rate control command to modify). 自动传输的数量、注册移动站的数量和/或其他因素可用于估计自动传输的需求量。 The number of automatic transmissions, the number of registered mobile stations, and / or other factors may be used to estimate the demand for an automatic transmission.

[0152] 在框730中,基站对接收的任何子数据包进行解码,可选地与以前接收的相应子数据包进行软组合,以判断这些数据包是否已经毫无差错地被接收。 [0152] In block 730, the base station for any sub-decoding the received data packets, optionally in combination with a soft respective previously received subpackets, to determine whether the packets have been received without error. 这些决定可用于向相应的发射移动站发送肯定性或否定性的确认。 These decisions may be used to send a positive or negative acknowledgment to the respective transmitting mobile stations. 如前所述,HARQ可用于R-ESCH上的数据包传输。 As described above, HARQ may be used for packet transmission on the R-ESCH. 也就是说,一个数据包可以被发送最多特定次数,直到它被至少一个基站正确接收。 That is, a packet may be transmitted up to certain number of times until it is received correctly at least one base station. 在每帧的边界处,各基站对R-RICH帧进行解码,并确定R-ESCH上的传输格式。 In each frame boundary, each base station decodes the R-RICH frame and determines the transmit format on the R-ESCH. 基站也可以使用当前的R-RICH帧和先前的R-RICH帧,做出该决定。 The base station may also use the current R-RICH frame and previous R-RICH frames, make this decision. 或者,基站也可以使用从反向辅助导频信道(R-SPICH)和/或R-ESCH中提取出的其他信息,做出该决定。 Alternatively, the base station may use other information from the reverse supplemental pilot channel (R-SPICH) and / or the R-ESCH extracted, and make the decision. 采用所确定的传输格式,在适当情况下,基站使用先前接收的子数据包,试图对R-ESCH上的数据包进行解码。 Using the determined transmission format, where appropriate, the base station using previously received subpackets, to attempt packet on R-ESCH decoded.

[0153] 在框740中,基站执行调度。 [0153] In block 740, the base station performs scheduling. 可以采用任何调度技术。 Any scheduling technique may be employed. 根据请求、预期自动传输、 当前信道状况的估计和/或各种其他参数,基站可以考虑传输需求,从而执行调度,分配共享资源(在该示例中为反向链路容量)。 According to the request, estimate the expected automatic transmission, the current channel conditions and / or various other parameters, the base station may consider the transmission requirements, thereby performing scheduling, allocation of a shared resource (reverse link capacity, in this example). 对于不同的移动站,调度可以采取不同的形式。 For different mobile stations, scheduling may take different forms. 示例包括:给予授权(根据请求分配、增加先前的授权或降低先前的授权)、产生增加、减少或保持先前授权速率或自动传输的速率控制命令,或者,忽略请求(将移动站恢复到自动传输)O Examples include: administering authorization (according to request allocation, increasing a previous grant or reducing a previous grant), generating an increase, decrease or maintain the previously authorized rate or automatic transmission rate control command, or ignore the request (to restore the mobile station to the automatic transmission ) O

[0154] 在步骤750中,对于每个移动站,基站处理所收到的传输。 [0154] In step 750, for each mobile station, the base station processes the received transmissions. 这包括:确认所收到的子数据包;有条件地生成授权,以响应传输请求。 This includes: acknowledgment received subpacket; generating conditionally authorized, in response to the transmission request. 图8示出了生成授权、确认和速率控制命令的示例性方法750。 FIG 8 shows generation authorization, an exemplary method of acknowledgment and rate control command 750. 它适用于图7所示的示例性方法700,也可用于其他方法,对于本领域技术人员来说这是显而易见的。 It applies to the exemplary method 700 illustrated in FIG. 7, may also be used in other methods, the skilled person would be apparent. 对于在方法700的每个步骤中的各活动移动站,方法750 可以重复,如上所述。 For each step in the process 700 in each of the active mobile stations, the method 750 may be repeated, as described above.

[0155] 在决策框805中,如果没有接收到当前正在处理的移动站的子数据包,则进入框810。 [0155] At decision block 805, if the sub-packet is not received in the mobile station currently being processed, the process proceeds to block 810. 不需要确认,也不发出速率控制命令。 No acknowledgment, rate control command is not issued. F-ACKCH和F-RCCH 二者都不需要发送,并且,两种符号都未被传输。 Both F-ACKCH and F-RCCH need not transmitted, and both symbols are not transmitted. 在决策框815中,如果收到请求,则转入决策框820中,否则,该流程停止。 At decision block 815, if the request is received, the process proceeds to decision block 820, otherwise, the process stops.

[0156] 在决策框820中,如果在调度期间已经确定了该移动站的授权,则转入框825,从而在适当的F-GCH上发送授权。 [0156] At decision block 820, if during the scheduling has been determined that the mobile station is authorized, the process proceeds to block 825 to transmit the grant on the appropriate F-GCH. 然后,该流程停止。 Then, the process stops. 移动站在下一合适帧期间,可以根据该授权进行发送(下面还将结合图10-12详细描述时序的例子)。 Mobile station during the next appropriate frame, can be (10-12 following example will be described in detail in conjunction with the timing chart) transmitted in accordance with the authorization.

[0157] 回到决策框805中,如果收到来自移动站的子数据包,则转入决策框830。 [0157] Back to decision block 805, if the received subpacket from the mobile station, the process proceeds to decision block 830. (应当注意的是,可能会接收到子数据包和请求,在这种情况下,会执行从805出来的两个分支, 为讨论清楚起见,这里没有给出其细节)。 (It should be noted, may receive the sub-packet and the request, in this case, from 805 performs two branches out, for clarity of discussion, there are no details given).

[0158] 在决策框830中,如果收到的子数据包被正确解码,则产生一个ACK。 [0158] At decision block 830, if the received subpacket was decoded correctly, then generates an ACK. 转入决策框835中。 Transferred to decision block 835. 如果希望进行速率控制(包括速率保持,即“继续”),则转入框845中。 If desired rate control (including a rate hold, i.e. "Continue"), the process proceeds to block 845. 如果不希望进行速率控制,则转入框840中。 If rate control is not desired, the process proceeds to block 840. 在框840中,通过F-ACKCH发送一个ACK_ST0P,即,产生一个DTX。 In block 840, the transmission through a ACK_ST0P F-ACKCH, i.e., generates a DTX. 如果此时未产生授权,则移动站进入自动传输(或者必须停止,如果自动传输不可用的话或者未被部署的话)。 If the authorization is not generated at this time, the mobile station enters an automatic transmission (or must stop, if the automatic transmission is not available, or not deployed if any). 或者,也可以发出一个新的授权,其覆盖停止命令。 Alternatively, you can issue a new license, which covers the stop command. 转入决策框820中,从而处理该决策,如上所述。 Transferred to decision block 820, so that the decision process, as described above.

[0159] 在框845中,指示了速率控制。 [0159] In block 845, the indication of the rate control. 因此,在F-ACKCH上传输ACK_RC。 Therefore, the transmission ACK_RC on F-ACKCH. 进入决策框850。 Proceed to decision block 850. 如果希望增速,则在F-RCCH上发送RATE_INCREASE。 If desired growth, transmitting RATE_INCREASE on F-RCCH. 然后,该流程可以停止。 Then, the flow can be stopped. 如果不希望增速,则转入决策框860中。 If you do not want growth, then transferred to decision block 860. 在决策框860中,如果希望减速,则在F-RCCH上传输RATE_ DECREASE。 At decision block 860, if the desired deceleration, the transmission RATE_ DECREASE on the F-RCCH. 然后,该流程可以停止。 Then, the flow can be stopped. 否则,在F-RCCH上传输RATE_H0LD。 Otherwise, the transmission RATE_H0LD on the F-RCCH. 在该示例中,速率保持由DTX来表示。 In this example, the retention rate is represented by the DTX. 然后,该流程可以停止。 Then, the flow can be stopped.

[0160] 返回决策框830中,如果收到的子数据包未被正确解码,则产生一个NAK。 [0160] Returning to decision block 830, if the received subpacket was not decoded correctly, a NAK is generated. 转入框875中,在F-ACKCH上发送NAK。 Transferred to block 875, sends a NAK on F-ACKCH. 在该示例中,NAK用DTX表示。 In this example, NAK represented by DTX. 进入决策框880中,判断收到的子数据包是不是最后一个子数据包(即,已经达到了最大数量的子数据包重传)。 Proceed to decision block 880, the judge received sub-packet is not the last sub-packet (ie, has reached the maximum number of sub-packet retransmission). 如果不是,在该示例中,则移动站可以根据先前的传输格式重传。 If not, in this example, the mobile station may retransmit according to the previous transmission format. 也可以在F-RCCH上传输DTX, 如框895所示。 DTX may be transmitted on F-RCCH, as indicated in block 895. (在这种情况下,其他实施例可以执行其他信令,下面将描述其示例)。 (In this case, other embodiments may perform other signaling, examples of which will be described below). 然后,该流程可以结束。 Then, the process may end.

[0161] 如果收到的、未经确认的子数据包是最后一个子数据包,则从决策框880转入决策框885中,以判断是否需要进行速率控制(包括速率保持)。 [0161] If the received unconfirmed subpacket is the last subpacket, decision block 880 proceeds from decision block 885 to determine the need for rate control (including a rate hold). 这是一种示例性的技术,用于以低开销来扩展先前授权或自动传输(包括先前的速率控制,如果有的话)。 This is an exemplary technique for low cost to extend previously authorized or automatic transmission (including previous rate control, if any). 如果不希望进行速率控制的话,则为F-RCCH生成一个DTX。 If rate control is not desired, then, for the F-RCCH generate a DTX. 在该示例中,移动站将发送下一个子数据包。 In this example, the mobile station sends the next sub-packet. 与决策框835类似,如果没有生成移动站的新授权,则移动站将进入自动传输(如果可用的话)。 Similarly the decision block 835, if a new grant is not generated in the mobile station, the mobile station will enter the automatic transmission (if available). 或者,可以生成一个新的授权,其规定移动站的可用传输。 Alternatively, it is possible to generate a new license, which predetermined mobile station transmission can be used. 转入决策框820中,以执行该判断,如上所述。 Transferred to decision block 820 to perform this determination, as described above.

[0162] 在决策框885中,如果需要进行速率控制,则转入决策框850。 [0162] At decision block 885, if rate control is required, the process proceeds to decision block 850. 可以产生在F-RCCH 上传输的增速、减速或速率保持,如上所述。 It may produce growth transmitted on F-RCCH, or deceleration rate remains, as described above. 然后,该流程可以停止。 Then, the flow can be stopped. [0163] 综上所述,如果数据包被正确接收,则基站可以向移动站发送肯定性确认,并且可以有条件地发送一条速率控制消息。 [0163] In summary, if a packet is received correctly, the base station may send positive acknowledgment to the mobile station, and may conditionally send a rate control message.

[0164] 基站可以发送ACK_ST0P (在F-ACKCH上),以表明数据包已经被传递,于是移动站返回自动模式,以进行下一次传输。 [0164] The base station may transmit ACK_ST0P (on F-ACKCH), to indicate that the packet has been transmitted, then the mobile station returns the automatic mode, in order for the next transfer. 基站还可以发送一个新的授权,如果需要的话。 The base station may also send a new authorization, if required. 移动站可以进行发送,最高达到下一次传输所授权的速率。 The mobile station may transmit up to the granted next transmission rate. 在每种情况下,都不传输F-RCCH。 In each case, no transmission of F-RCCH. 在一个实施例中,只有一个服务(或授权)基站可以产生授权。 In one embodiment, only a serving (or authorized) base station may generate authorization. 在另一实施例中,一个或多个基站可以产生授权(处理该选项的细节将在下面进行描述)。 In another embodiment, the one or more base stations may generate a grant (details of the process option will be described below).

[0165] 基站可以发送ACK_RC (在F-ACKCH上)和RATE_H0LD (在F-RCCH上),以表明:数据包已被传递,并且,移动站可以发送下一数据包的最高速率与当前数据包的传输速率相同。 [0165] The base station may send ACK_RC (on F-ACKCH) and RATE_H0LD (on F-RCCH), to indicate: the data packet has been transferred, and the maximum rate the mobile station may transmit the next packet with the current packet the same transmission rate.

[0166]基站可以发送 ACK_RC (在F-ACKCH 上)和RATE_INCREASE (在F-RCCH 上),以表明:数据包已被传递,并且,移动站可以相对于当前数据包的传输速率提高下一次数据包传输的最大速率。 [0166] The base station may send ACK_RC (on F-ACKCH) and RATE_INCREASE (on F-RCCH), to indicate: the data packet has been transmitted, and the mobile station may first data with respect to the current transmission rate of the data packet increases the maximum transmission rate of the packet. 按照基站和移动站都知道的特定规则,移动站可以提高速率。 In accordance with specific rules and the mobile station knows that the base station, the mobile station may increase the rate. 增速可以是确定性的或者概率性的。 The growth rate may be deterministic or probabilistic. 本领域技术人员可以理解提高速率的多种规则。 Those skilled in the art will be appreciated that increasing the rate of multiple rules.

[0167]基站可以发送 ACK_RC (在F-ACKCH 上)和RATE_DECREASE (在F-RCCH 上),以表明:数据包已被传递,并且,移动站可以相对于当前数据包的传输速率降低下一次数据包传输的最大速率。 [0167] The base station may send ACK_RC (on F-ACKCH) and RATE_DECREASE (on F-RCCH), to indicate: the data packet has been transmitted, and the mobile station may first data with respect to the current transmission rate of the data packet is reduced the maximum transmission rate of the packet. 按照基站和移动站都知道的特定规则,移动站可以降低速率。 In accordance with specific rules and the mobile station knows that the base station, the mobile station may decrease the rate. 减速可以是确定性的或者概率性的。 Deceleration may be deterministic or probabilistic. 本领域技术人员可以理解降低速率的多种规则。 Those skilled in the art will be understood multiple rules reduced rate.

[0168] 如果基站没有成功接收到某一数据包,并且,可以进一步重传该数据包(即,不是最后一个子数据包),则基站在F-ACKCH上发送一个NAK。 [0168] If the base station is not successfully received a data packet, and may be further retransmit the data packet (i.e., not the last subpacket), the base station sends a NAK on F-ACKCH. 注意,在该示例中,F-RCCH未被传输。 Note that, in this example, F-RCCH is not transmitted.

[0169] 如果对于该数据包(S卩,最后一个子数据包)不允许进一步的重传,则基站可以采取以下的可能动作。 [0169] If further retransmission is not allowed for the packet (S Jie, last subpacket), the base station can take the following possible actions. 基站可以(在F-ACKCH上)发送NAK以及同时在F-GCH上发送授权消息,以告知移动站:该数据包未被传递;对于下一次传输,移动站可以按照高达所授权的速率进行传输。 The base station may (on F-ACKCH) and simultaneously transmit authorization transmits NAK message on F-GCH, to inform the mobile station: the data packet is not transmitted; may be transmitted for the next transmission, the mobile station according to the granted rate up . 在这种情况下,不传输F-RCCH。 In this case, no transmission of F-RCCH. 在一个实施例中,只有一个服务(或授权)基站可以产生授权。 In one embodiment, only a serving (or authorized) base station may generate authorization. 在另一实施例中,一个或多个基站可以产生授权(处理该选项的细节将在下面进行描述)。 In another embodiment, the one or more base stations may generate a grant (details of the process option will be described below).

[0170] 基站也可以发送NAK (在F-ACKCH上)和RATE_H0LD (在F-RCCH上),以表明:数据包未被传递,并且,移动站可以发送下一数据包的最高速率与当前数据包的传输速率相同。 [0170] The base station may also send a NAK (on F-ACKCH) and RATE_H0LD (on F-RCCH), to indicate: the data packet is not passed, and the maximum rate the mobile station may transmit the next packet with the current data the same packet transmission rate. [0171 ] 基站也可以发送NAK (在F-ACKCH上)和RATE_INCREASE (在F-RCCH上),以表明: 数据包未被传递,并且,移动站可以相对于当前数据包的传输速率提高下一次数据包传输的最大速率。 [0171] The base station may also send a NAK (on F-ACKCH) and RATE_INCREASE (on F-RCCH), to indicate: the data packet is not transmitted, and the mobile station may transmit a relative rate of current packet improved the maximum rate of data packet transmission. 按照基站和移动站都知道的特定规则,移动站可以提高速率。 In accordance with specific rules and the mobile station knows that the base station, the mobile station may increase the rate. 增速可以是确定性的或者概率性的。 The growth rate may be deterministic or probabilistic.

[0172] 基站也可以发送NAK (在F-ACKCH上)和RATE_DECREASE (在F-RCCH上),以表明: 数据包未被传递,并且,移动站可以相对于当前数据包的传输速率降低下一次数据包传输的最大速率。 [0172] The base station may also send a NAK (on F-ACKCH) and RATE_DECREASE (on F-RCCH), to indicate: the data packet is not transmitted, and, with respect to a mobile station may lower the current transmission rate decrease data packet the maximum rate of data packet transmission. 移动站可以降低速率,按照基站和移动站都知道的特定规则。 The mobile station may decrease the rate, in accordance with specific rules base and mobile stations are aware of. 降低可以是确定性的或者概率性的。 Reduction may be deterministic or probabilistic.

[0173] 在另一实施例(图8未给出其细节)中,可以创建“NAK and stop”的替代物。 [0173] Example (details not shown in FIG. 8) in another, can create "NAK and stop" alternative. 例如,在上面的情形中,与NAK对应的F-RCCH上的DTX无法与NAK-and-hold区分开来。 For example, in the above case, and the DTX on F-RCCH corresponding NAK can not be separated NAK-and-hold area to. 如果需要一条命令来强制停止(或回到自动传输),则在最后一个子数据包之前基站也可以使用NAK和速率控制,以表明:关于最后一个子数据包的速率保持(或增加或降低)意味着停止。 If required to force a stop command (or return to automatic transmission), the base station may be used before the last subpacket NAK and rate control, to indicate: the rate on the last sub-packet holding (or increase or decrease) It means stop. 例如,可以分配任何一个速率控制命令(即,RATE_INCREASE、RATE_DECREASE或RATE_HOLD),在这种特定情况下表示停止。 For example, one can assign any rate control command (i.e., RATE_INCREASE, RATE_DECREASE, or RATE_HOLD), in this particular case represented stopped. 移动站知道最后一个子数据包是何时传输的,然后可以相应地解析速率控制命令。 The mobile station knows the last sub-packet is transmitted when, can then parse the rate control commands accordingly. 当移动站知道在NAK情况下最后一个子数据包传输之后应当是停止时,则可以用前一子数据包的NAK,发出所选的速率控制命令。 When the mobile station knows when the NAK after a last sub-packet transmission should be stopped, the NAK previous sub-packet may be used, the selected rate control command issued. 接收到识别出的速率控制命令以及子数据包(不是最终的)的NAK的移动站知道:对最后一个子数据包的NAK(和RATE_HOLD,例如)意味着以前的任何授权都必须被撤消,并且,移动站必须回到自动传输。 Receiving the identified rate control command and a sub-packet (not the final) of the mobile station knows NAK: NAK for the last sub-packet (and RATE_HOLD, for example) means that any previous authorization must be withdrawn, and , the mobile station must return to the automatic transmission. 不用于该目的的速率控制命令(即,RATE_INCREASE或RATE_DECREASE),与最后的子数据包NAK—起传输,仍是可用的。 Rate is not used for this purpose a control command (i.e., RATE_INCREASE, or RATE_DECREASE), and the last sub-packet transmission from NAK-, is still available. 另一种做法是,与最后的NAK —起发送具有零(或较低)速率的授权,但是这需要附加的开销。 Another approach, with the final NAK - send an authorization from a zero (or lower) rates, but this requires additional overhead. 根据“NAK-and-Stop”的概率以及其他可能性, 本领域技术人员很容易在这些选择之间做出权衡。 According to the probability of "NAK-and-Stop" as well as other possibilities, one skilled in the art will readily tradeoff between these choices. 然后,基于这些不同事件的概率,可以优化所需的开销。 Then, based on the probability of these different events, you can optimize the required overhead.

[0174] 图9给出了让移动站监视和响应授权、确认和速率控制命令的示例性方法900。 [0174] Figure 9 shows a mobile station to monitor and respond so authorized, an exemplary method of acknowledgment and rate control command 900. 该方法适用于将一个或多个移动站与上述采用方法700的一个或多个基站以及其他基站实施例结合起来使用。 This method is suitable for one or more mobile stations using the method described above and one or more base stations 700 and other base station embodiments in combination.

[0175] 该流程开始于框910。 [0175] The process begins in block 910. 移动站监视F-GCH、F-ACKCH和F-RCCH。 The mobile station monitors the F-GCH, F-ACKCH and F-RCCH. 要注意的是,在上述各实施例中,移动站可以监视一个或多个这样的信道。 It is noted that, in the above embodiments, the mobile station may monitor one or more of such channels. 例如,也可能有多个授权信道,每个移动站可以监视它们中的一个或多个。 For example, there may be multiple grant channels, each mobile station may monitor one or more of them. 还应当注意,可以从一个移动站接收到这些信道中的每一个,或者,当移动站处于软切换状态时,接收到一个以上的信道。 It should also be noted, may be received from a mobile station to each of these channels, or, when the mobile station is in soft handoff, the received one or more channels. 一个信道可以加入指向多个移动站的消息或命令,所以,移动站可以提取专门指向它的消息或命令。 One channel may be added to messages or commands directed to multiple mobile stations, the mobile station may extract special messages or commands directed to it.

[0176] 可以采用其他准则,以使移动站有条件地监视一个或多个控制信道。 [0176] Other criteria can be used to make the mobile station to conditionally monitor one or more control channels. 例如,如上所述,当发出ACK_ST0P时,不发送F-RCCH。 For example, as described above, when issuing ACK_ST0P, does not transmit the F-RCCH. 因此,在这种情形下,当收到ACK_ST0P时,移动站不必监视F-RCCH。 Thus, in this case, when receiving ACK_ST0P, the mobile station need not monitor the F-RCCH. 可以指定一条规则,只有移动站发送了可以被响应的请求时,移动站才寻找授权消息和/或速率控制命令。 You can specify a rule, only the mobile station may be transmitted in response to the request, the mobile station looking only authorized messages and / or rate control command.

[0177] 在下面对图9的描述中,假设:移动站以前发送了一个子数据包,期望收到对它的确认(包括潜在的授权或速率控制命令)响应。 [0177] In the following description of FIG. 9, it is assumed: transmitting a sub-packet before the mobile station, it expects to receive an acknowledgment (including potential or rate control command authorization) response. 如果以前没有授权某一请求,则移动站仍监视授权,以响应以前发送的请求。 If a previous request is not authorized, the mobile station is still monitoring authorized, in response to the request previously sent. 本领域技术人员可以很容易地将方法900适用于这种情形。 Those skilled in the art can readily apply the method 900 to such a case. 为了清楚起见,对这些和其他潜在的移动站处理模块不再赘述。 For clarity, these and other potential mobile station processing module omitted.

[0178] F-ACKCH的处理开始于决策块915。 [0178] F-ACKCH process 915 begins at decision block. 移动站提取它所监视的所有F-ACKCH信道的有关信息。 It monitors the mobile station extracts information on all the F-ACKCH channel. 如前所述,在移动站和它的F-ACKCH活动集合的每个成员之间可能存在F-ACKCH。 As described above, there may be the F-ACKCH between the mobile station and every member of its F-ACKCH active set. 可以对有些F-ACKCH命令进行软组合,就如同L3信令所指明的那样。 Some may be soft combined F-ACKCH commands as specified as L3 signaling. 如果移动站收到至少一个肯定性确认,ACK_RC或ACK_ST0P (在F-ACKCH上),则当前数据包已被正确接收,所以不必再传输附加的子数据包。 If the mobile station receives at least one positive acknowledgment, ACK_RC or ACK_ST0P (on F-ACKCH), the current packet has been received correctly, it is not necessary the additional retransmission subpacket. 传输下一数据包(如果有的话)所容许的速率需要确定。 Transmit the next packet (if any) allowed to determine the required rate.

[0179] 在决策框915中,如果收到ACK_ST0P,则移动站知道:以前发送的子数据包已被正确接收,不必对速率控制命令进行解码。 [0179] At decision block 915, if the received ACK_ST0P, the mobile station knows: previously transmitted subpacket has been received correctly, not necessarily on the rate control command is decoded.

[0180] 在决策框920中,移动站判断是否在F-GCH上收到了授权。 [0180] At decision block 920, the mobile station determines whether it has received a grant on F-GCH. 如果是,则移动站根据该授权发送下一数据包,如框930所示。 If so, the mobile station transmits the next packet according to the authorization, as shown in block 930. 在一个实施例中,只有一个授权基站做出授权。 In one embodiment, only one authorized to make authorization station. 如果收到来自基站的ACK_ST0P和授权消息,则移动站按照等于或低于授权速率的速率,在相同的ARQ信道上发送一个新数据包。 If authorization is received and ACK_ST0P message from the base station, the mobile station at a rate equal to or below the authorized speed, transmitting a new packet on the same ARQ channel.

[0181 ] 在另一实施例中,不止一个基站可以发送授权。 [0181] In another embodiment, more than one base station may send an authorization. 如果基站协调授权并发送相同的消息,则移动站可以将这些授权进行软组合。 If the base station and the authorization coordinate send the same message, the mobile station may authorize these soft compositions. 当收到不同的授权时,可以采用各种规则,来处理这些情况。 Upon receipt of a different authorization, various rules may be employed to deal with these situations. 一个例子是,移动站按照收到的授权中指定的最大速率进行发送,以避免对应于相应授权基站的蜂窝中的过度干扰(包括ACK_ST0P,而没有相应的授权,这表明传输应当回到自动模式)。 One example is that the mobile station transmits in accordance with authorization received specified maximum rate, to avoid the base station corresponding to the respective authorized excessive interference in the cell (including ACK_ST0P, without corresponding authorization, indicating that transmission should return to the automatic mode ). 对于本领域技术人员来说,各种其他方式也是显而易见的。 For skilled in the art, it is also evident in various other ways. 在决策框920中如果没有收到授权,则移动站必须返回自动速率,如框925所示。 At decision block 920 if authorization is not received, the mobile station must return to autonomous rate, as shown in block 925. 然后,流程结束。 Then, the process ends.

[0182] 回到决策框915,如果没有收到ACK_ST0P,则进入决策框940。 [0182] back to decision block 915, if not received ACK_ST0P, proceed to decision block 940. 如果收到了ACK_RC, 则移动站监视肯定性确认(如果有的话)所来自的基站的相应F-RCCH。 If the received ACK_RC, the mobile station monitors positive acknowledgment corresponding F-RCCH (if any) from the base station. 应当注意的是,基站和移动站之间可能没有F-RCCH,因为F-RCCH活动集合是F-ACKCH活动集合的一个子集。 It should be noted, may not F-RCCH between a base station and a mobile station, since the F-RCCH Active Set is a subset of the active set of F-ACKCH. 还应当注意的是,当移动站收到来自多个基站的F-ACKCH时,相应的消息可能会冲突。 It should also be noted that, when the mobile station receives F-ACKCH from multiple base stations, the corresponding messages may collide. 例如,可能会收到一个或多个ACK_ST0P命令,也可能收到一个或多个ACK_RC命令,也可能收到一个或多个授权,或者其组合。 For example, you may receive one or more command ACK_ST0P may also receive one or more ACK_RC commands may also receive one or more authorized, or combinations thereof. 本领域技术人员能够理解用于容纳这些可能性的各种规则。 Those skilled in the art to understand the rules for receiving these possibilities. 例如,移动站可以决定可能最低的传输准许(可能来自没有授权的ACK_ST0P、带有减速的ACK_RC或具有更低值的授权),并相应地进行发送。 For example, the mobile station may determine the lowest possible transmission permission (which may come from unauthorized ACK_ST0P, with authorization or deceleration ACK_RC has a lower value) and transmit accordingly. 这类似于名为“OR-of-Downs”准则的技术。 This is similar technology called "OR-of-Downs" criteria. 这样的技术可用于严格地避免过度干扰相邻蜂窝。 Such techniques may be used to strictly avoid excessive interference to adjacent cells. 或者,一个或多个基站可以具有分配给它们的优先级,从而,一个或多个基站可以超过其他基站(可能带有附加条件)。 Alternatively, one or more base stations may have a priority thereof assigned to one or more base stations other than the base station may (possibly with additional conditions). 例如,调度(或授权)基站的优先级可能高过处于软切换状态的其他基站。 For example, priority scheduling (or authorized) base stations may be higher than other base stations in soft handover state. 其他准则也是可以预期到的(如前所述,可能也收到一个或多个NAK,但移动站不需重发。不过,移动站可以以相似的方式,加入来自未确认基站速率控制命令或授权,如果需要的话)。 Other criteria may also contemplated (as described above, may also receive one or more NAK, but the mobile station need not retransmit. However, a mobile station may in a similar manner, the base station is added from a rate control command is not confirmed or authorization, if required). 为便于讨论,当一个移动站判断接收到ACK_ST0P、ACK_RC、NAK或授权时,结果可能是,将预期的规则集合应用于多个接收命令,然后识别出命令。 For ease of discussion, when a mobile station determines whether the received ACK_ST0P, ACK_RC, NAK, or authorized, the result may be a set of rules applies to a plurality of expected reception command, then the command identified.

[0183] 如果已经收到ACK_RC,则转入决策框945,开始判断应该服从何种类型速率控制命令。 [0183] If you have already received ACK_RC, then transferred to decision block 945 to begin determining what type of rate control command should obey. 如果表示增速,则进入框950。 If growth is expressed, the process proceeds to block 950. 可以按照比当前速率增加的速率,在同一ARQ信道上发送下一传输。 It may send the next transmission on the same ARQ channel in accordance with the rate of increase over the current rate. 然后,流程结束。 Then, the process ends. 同样,增速可以是确定性的或者是概率性的。 Similarly, the growth rate may be deterministic or probabilistic. 此外,RATE_ INCREASE未必导致立即的速率增加,而可能是在将来提高来自移动站的传输速率(即,在移动站中使用信用式算法),或者,RATE_INCREASE可能导致多个速率的增加。 Further, RATE_ INCREASE does not necessarily result in immediate rate increase, and probably increase the transmission rate from the mobile station in the future (i.e., a credit-type algorithm used in the mobile station), or, RATE_INCREASE may result in increased rates of a plurality. 在一个示例性的信用卡式算法中,移动站维持内部的“平衡/信用”参数。 In an exemplary credit card type algorithm, a mobile station maintains an internal "balance / credit" parameter. 当它收到RATE_INCREASE但却无法增加其速率时(因为没有电或数据),移动站增加该参数。 When it receives RATE_INCREASE but can not increase its rate (because no power or data), the mobile station increases the parameter. 当移动站有电或数据时, 它可以使用存储的“信用/平衡”来选择数据速率。 When the mobile station has power or data, it can use the stored "credit / balance" to select the data rate. 对于领域技术人员来说,各种增速的方式是显而易见的。 For the skilled person, the growth rate of the various ways will be apparent.

[0184] 如果在决策框945中没有显示增速,则进入框955中,判断是否指示减速。 [0184] If no growth at decision block 945, the process proceeds to block 955, it is determined whether the deceleration indication. 如果指明了减速,则进入框960中。 If specified deceleration, the process proceeds to block 960. 可以按照比当前速率降低的速率,在相同的ARQ信道上发送下一传输。 May send the next transmission on the same ARQ channel in accordance with the rate of reduction from the current rate. 然后,流程结束。 Then, the process ends. 同样,增速可以是确定性的或者是概率性的。 Similarly, the growth rate may be deterministic or probabilistic. 此外,RATE_ DECREASE可能未必导致立即的速率降低,而是在将来降低来自移动站的传输速率(即,在移动站中使用信用式算法),或者,RATE_DECREASE可能导致多个速率的降低。 Further, RATE_ DECREASE may not necessarily result in immediate rate decrease, but to reduce the transmission rate from the mobile station (i.e., a credit-type algorithm used in the mobile station), or in the future, RATE_DECREASE may result in reduced rates of a plurality. 当一个示例性的信用算法用在RATE_DECREASE环境中时,当移动站得到RATE_DECREASE但却由于某种原因没有服从时(例如,需要发送紧急数据),它得到否定性信用,而该否定性信用需要以后进行偿还。 When an example credit algorithm is used in the RATE_DECREASE context, when a mobile station to obtain RATE_DECREASE but due to some reason does not obey (e.g., urgent need to send data), it gets negative credit, and this negative credit needs after be repaid. 对于领域技术人员来说,各种减速的方式是显而易见的。 For the skilled person, various ways will be apparent to the deceleration. [0185] 如果既没有指示增速也没有指示减速,则收到的是RATE_H0LD。 [0185] If neither growth nor indication indicates deceleration, it is received RATE_H0LD. 移动站可以按照与当前数据包速率相等的最大速率,进行发送,如框965所示。 The mobile station can follow a current equal to the maximum rate packet rate, transmission as shown in block 965. 然后,流程结束。 Then, the process ends.

[0186] 回到决策框940中,如果没有识别出任何类型的ACK,则确定收到了NAK。 [0186] Back to decision block 940, if not identify any type of ACK, the determined received NAK. 在决策框970中,如果数据包传输仍有可能的话(即,当前子数据包不是最后的子数据包),则移动站在相同的ARQ信道上,用增加后的子数据包ID,重发该子数据包,如框980所示。 At decision block 970, if the data packet transmission is still possible (i.e., the current subpacket was not the last subpacket), the mobile station the same ARQ channel, the packet ID of the sub-data increases, the retransmission the sub-packet, as shown in block 980.

[0187] 在决策框970中,如果当前数据包是最后的子数据包,则移动站已经用完了该数据包的重传。 [0187] At decision block 970, if the current packet was the last subpacket, the mobile station has run out of the retransmission data packet. 进入决策框975中,以判断是否收到授权(与上面结合框920所示的方式相似)。 Proceed to decision block 975 to determine whether authorization is received (in the manner shown above in connection with block 920 is similar). 如果授权消息是指定到移动站的(不管来自单个基站,还是一个以上基站,如前所述),移动站可以按照等于或低于授权速率的速率,在相同的ARQ信道上发送新的数据包。 If a grant message is designated to the mobile station (whether from a single base station, or more than one base station, as described above), the mobile station can follow the rate equal to or below the authorized speed, transmits a new packet on the same ARQ channel . 然后,进入上述的框930。 Then, into the above-described block 930.

[0188] 在决策框975中,如果没有收到授权,则移动站监视F-RCCH活动集合,获得速率控制命令,然后决定在相同ARQ信道上进行下一数据包传输所容许的最大速率。 [0188] At decision block 975, if no authorization is received, the mobile station monitors the F-RCCH Active Set, obtain rate control commands, and decide the maximum rate for next packet transmission on the same ARQ channel is allowed. 当收到不止一个速率控制命令时,可以执行如上所述的速率选择。 When more than one rate control command is received, the rate selection may be performed as described above. 进入决策框945中并继续,如上所述。 Proceed to decision block 945 and continue as described above.

[0189] 移动站的一个示例性实施例可以采用各种其他技术。 [0189] An exemplary embodiment of a mobile station that various other techniques may be employed. 移动站可以监视数据包删除的次数(即,在最后一个子数据包之后没有肯定性确认)。 The mobile station may monitor the number of deleted packets (i.e., no positive acknowledgment after the last subpacket). 在一个窗口(即,滑动窗口)内统计被删除数据包的数量或连续数据包删除的次数,可以进行测量。 Count the number of times the number of packets to be deleted or continuous deleted packets in a window (i.e. a sliding window) within, it can be measured. 如果移动站发现太多的数据包已被删除,则它可以降低自己的传输速率,即便速率控制命令表示其他命令(即, RATE_H0LD 或RATE_INCREASE)。 If the mobile station has found a lot of packets is deleted, it is possible to reduce their transmission rate, even if the rate control command indicates another command (i.e., RATE_H0LD or RATE_INCREASE).

[0190] 在一个实施例中,授权消息可以具有比速率控制比特要高的优先级。 [0190] In one embodiment, a grant message may have higher than a rate control bit priority. 或者,授权消息可被视为与速率控制比特具有相同的优先级。 Alternatively, authorization messages may be considered with a rate control bit has the same priority. 在这种情况下,可以修改速率确定。 In such a case, rate determination may be modified. 例如, 如果没有授权消息指定到移动站,则使用“OR-of-DOWN”或类似准则,根据所有的速率控制命令(RATE_INCREASE、RATE_HOLD、RATE_DECREASE 和ACK_ST0P),确定下一传输速率。 For example, if no grant message to the specified mobile station, using "OR-of-DOWN" or similar criteria, control commands (RATE_INCREASE, RATE_HOLD, RATE_DECREASE, and ACK_ST0P) The rate of all, determines the next transmission rate. 当也收到授权时,使用“OR-of-DOWN”或类似准则,根据所有的速率控制命令(RATE_INCREASE、 RATE_H0LD、RATE_DECREASE和ACK_ST0P),确定下一传输速率,将其结果与授权速率和所选的较小速率进行比较。 When also receives the authorization, using the "OR-of-DOWN" or similar criteria, according to which all control rate command (RATE_INCREASE, RATE_H0LD, RATE_DECREASE and ACK_ST0P), determines the next transmission rate, which rate and the selected result and authorization the smaller rate compared.

[0191] 可以采用信令来配置移动站,从而使移动站仅监视来自服务基站或F-RCCH活动集合中所有基站的F-RCCH指示。 [0191] Signaling may be used to configure the mobile station so that the mobile station monitors only a set of serving base station or from the F-RCCH activity F-RCCH indicating all base stations. 例如,当RATE_C0MB_IND表明速率控制命令与来自多个基站的相同时,移动站可以将识别出来的组中的所有指示进行组合,然后做出决策。 For example, when an indication indicating that all groups RATE_C0MB_IND rate control command is the same from multiple base stations, the mobile station can be recognized in combination, and make decisions. 在任何时间使用的不同指示的数量可以被显示为F-RCCH当前集合。 It indicates the number of different used at any time may be displayed as the current set of F-RCCH. 在一个示例中,移动站可以只监视来自服务基站的F-RCCH指示,这种情况下,F-RCCH当前集合的大小是1。 In one example, the mobile station can monitor only the F-RCCH indication from the serving base station, in this case, the size of the F-RCCH is a current collection.

[0192] 此外,如上所述,可采用各种准则来调节速率,以响应F-RCCH上的命令。 [0192] As described above, various criteria may be employed to adjust the rate, in response to commands on the F-RCCH. 这些准则可由来自基站的信令进行调整。 These criteria may be adjusted from the base station signaling. 在一个示例中,有一组概率和步长,用于确定移动站增加或降低其速率以及量。 In one example, there is a set of probabilities and step size for determining the rate of increase or decrease its amount, and the mobile station. 这些概率和可能的速率步长可以通过信令进行更新,如果必要的话。 These probabilities and possible rate step sizes may be updated through signaling, if necessary.

[0193] 如上所述,可以改编方法900,以包括采用了方法750的基站的各种替代物。 [0193] As described above, the method 900 may be adapted to a variety of alternatives including the use of a method 750 of the base station. 例如, 在一个实施例中,没有明确定义“NAK and stop”命令,因为F-RCCH上的DTX连同NAK—起表示速率保持。 For example, in one embodiment, there is no clear definition of "NAK and stop" command, as a DTX on F-RCCH along with retention rate expressed from NAK-. 在另一实施例中,可采用“NAK and stop”功能,以响应方法750所述的任一技术。 In another embodiment, the employed "NAK and stop" function, in response to any of the techniques according to the method 750. 此外,如上结合方法750所述的那样,在该示例性实施例中,基于速率控制或基于授权的速率改变在数据包边界上执行。 Further, as described above in conjunction with the method 750, in the exemplary embodiment, rate control or change the rate of execution based authorization based on a packet boundary. 可以预期的是,可以修改所描述的方法,以具体化子数据包间速率改变。 It is contemplated that the methods described may be modified, inter packet rate change specific facilitator.

[0194] 通过阅读这里公开的内容,本领域技术人员应当明白,可以通过各种方式将这里描述的过程和特征进行组合。 [0194] By reading the disclosure herein, those skilled in the art will appreciate, the process and features described herein may be combined in various ways. 例如,移动站只由主基站通过授权进行控制,而不是由其他基站通过速率控制比特进行控制。 For example, the mobile station is controlled by only authorized by the primary base station, rather than through other base stations controlled by the rate control bits. 或者,通过来自所有基站或其活动集合中的一部分基站的授权,也可以控制移动站。 Alternatively, a portion of the authorization from the base station, or all base stations in the active set, the mobile station can be controlled. 可以对有些F-GCH进行软组合。 It can be soft combined for some F-GCH. 移动站的工作模式可以在信道分配期间通过L3信令或在分组数据呼叫期间通过其他消息建立。 Mode of operation by the mobile station may L3 signaling during channel assignment or via other messages during the establishment of a packet data call.

[0195] 再例如,如果一个数据包被正确接收,则主基站可以发送ACK_ST0P或ACK_RC。 [0195] As another example, if a packet is received correctly, the primary base station may send ACK_ST0P or ACK_RC. 可以不使用速率控制命令,从而使用ACK_RC来表示该模式的“ACK and continue”。 Rate control command may not be used, thus ACK_RC used to represent the pattern of "ACK and continue". 在这种环境下,“ACKand continue”表示移动站可以按照与被确认的数据包相同的速率,发送一个新的数据包。 In this context, "ACKand continue" indicates that the mobile station may be in accordance with the acknowledgment packet at the same rate, a new packet transmission. 如前所述,如果发送了ACK_ST0P,则基站可以在F-GCH上发送一个最重要的授权,指定到MS。 As described above, if the transmitted ACK_ST0P, the base station may send one of the most important grant on F-GCH, designated to the MS. 在该示例中,NAK表示“NAK and stop”,除非相应的授权与NAK—起传输。 In this example, NAK indicates "NAK and stop", unless a corresponding license from the transmission NAK-. 在这种情况下,非主基站也发送ACK_ST0P或ACK_RC,其中,ACK_RC没有伴随着速率控制命令,从而表示"ACK and continue,,。 In this case, the non-primary base stations also send ACK_ST0P or ACK_RC, wherein, ACK_RC is not accompanied by a rate control command, thereby representing "ACK and continue ,,.

[0196] 在另一集成了所描述的一部分特征的示例性专用模式下,移动站可以只通过速率控制比特(来自其F-RCCH活动集合中的基站)进行控制。 [0196] In another integrated part of the features described exemplary dedicated mode, the mobile station may only be controlled by the bit rate (from which F-RCCH of base stations in the active set) is controlled. 可以通过信道分配期间的L3信令或分组数据呼叫期间的其他消息,确立该模式。 Other or L3 signaling messages during a packet data call may be assigned during a channel, the established pattern. 在这种模式下,如果数据包未被成功接收,则基站发送NAK。 In this mode, if the data packet is not successfully received, the base station transmits NAK. 当数据包被正确接收时,基站将ACK_ST0P或ACK_RC与F-RCCH(RATE_ HOLD、RATE_INCREASE或RATE_DECREASE) —起发送。 When a packet is received correctly, the base station or ACK_RC ACK_ST0P and F-RCCH (RATE_ HOLD, RATE_INCREASE, or RATE_DECREASE) - starting transmission. 最后一个子数据包之后的NAK可能伴随着F-RCCH (RATE_H0LD、RATE_INCREASE 或RATE_DECREASE)。 NAK after the last subpacket may be accompanied with the F-RCCH (RATE_H0LD, RATE_INCREASE, or RATE_DECREASE).

[0197] 图10-12中的例子示出了这里描述的各种信道的时序图。 [0197] The example in Figure 10-12 shows a timing diagram of various channels described herein. 这些例子并不表示帧长度的任何特定选择,而是说明授权、ACK和速率控制(RC)指示的相对时机。 These examples do not represent any specific choice of frame length, but illustrate relative timing of authorization, ACK, and rate control (RC) indication. ACK指示、RC 指示和授权出现在相同的时间间隔内,从而,移动站大约在相同时间收到ACK、RC和授权信息,以应用于下一数据包传输。 ACK indicator, indicating the RC and authorization occur within the same time interval, thus, the mobile station receives ACK approximately, the RC and grant information at the same time, it applied to a next data packet transmission. 在这些例子中,移动站不必监视RC指示,除非它收到确认时或已发送所有子数据包时(如上面的示例性实施例所描述的那样)。 In these examples, the mobile station need not monitor the RC indicated, unless it receives an acknowledgment or all subpackets have been transmitted (as above exemplary embodiments described embodiment). 移动站监视分配给它的ACK比特和与该特定ARQ序列相对应的RC指示。 The mobile station monitors the ACK bit assigned to it and to the particular ARQ sequence corresponding to the RC indicator. 例如,如果有四个ARQ序列并且移动站在所有ARQ上进行发送,则移动站在每帧监视ACK指示,在每帧监视RC指示(如果适当的话)。 For example, if there are four ARQ sequences, and the mobile station transmitting on all ARQ, the mobile station monitors the ACK indicator every frame, every frame monitoring RC indicator (if appropriate). 在不同传输之间引入空帧,从而,如何适当的话,基站或移动站能够有时间对请求、子数据包传输、授权、确认和速率控制命令进行接收和解码。 Air is introduced between the different transmission frames, thereby, how appropriate, a base station or a mobile station can request time, the sub-packet transmission, authorization, acknowledgment and rate control commands received and decoded.

[0198] 应当注意的是,这些时序图并非穷举性的,而是仅仅用来说明这里描述的各个方面。 [0198] It should be noted, is not exhaustive of the timing diagram, but merely to illustrate various aspects described herein. 本领域技术人员应当理解各种序列组合。 Those skilled in the art should appreciate that various combinations of sequences.

[0199] 图10是具有组合的确认和速率控制信道的示例性实施例的时序图。 [0199] FIG. 10 is a combined acknowledgment and rate control channels with an exemplary embodiment of a timing diagram of the embodiment. 移动站发送请求,以在R-REQCH上进行传输。 The mobile station sends a request to the transmission on the R-REQCH. 于是,基站在F-GCH上发送授权,以响应该请求。 Then, the base station transmits the grant on F-GCH, in response to the request. 然后,移动站使用根据该授权的参数,发送第一个子数据包。 Then, the mobile station using the parameters of the authorization, the first sub-packet transmission. 在基站中,该子数据包未被正确解码, 如该子数据包传输失败所表示的那样。 In the base station, the sub-data packet is not decoded correctly, such as the sub-data packet transmission failures indicated. 基站在F-ACKCH上发送ACK/NAK传输,同时在F-RCCH 上发送速率控制命令。 The base station transmits ACK / NAK transmission on the F-ACKCH, while the transmission rate control command on the F-RCCH. 在该示例中,发送的是NAK,F-RCCH停止传输。 In this example, the transmission is a NAK, F-RCCH stop transmission. 移动站收到NAK,并且,作为响应,重发第二个子数据包。 The mobile station receives the NAK, and, in response, a second retransmission sub-packet. 这时,基站对第二个子数据包进行了正确解码,因此, 在F-ACKCH上发送ACK/NAK传输,同时在F-RCCH上发送速率控制命令。 At this time, the second child base station has correctly decoded data packet, thus transmitting ACK / NAK transmission on the F-ACKCH, while the transmission rate control command on the F-RCCH. 在该示例中,不发送附加的授权。 In this example, it does not send additional authorization. 发送ACK_RC,并发布速率控制命令(它可能表示根据预期调度决定的增速、 减速或保持速率)。 Send ACK_RC, and release rate control command (which may be represented in accordance with the expected growth of scheduling decisions, or maintain the rate of deceleration). 然后,移动站使用与该授权相关联的参数,发送下一数据包的第一个子数据包,这些参数由F-RCCH上的速率控制命令根据需要进行修改。 Then, the mobile station uses the authorization parameter is associated with, a first sub-packet transmission of the next data packet, which is controlled by the rate on the F-RCCH need to be modified according to the command.

[0200] 图11是一个具有组合的确认和速率控制信道以及还有新授权的示例性实施例的时序图。 [0200] FIG. 11 is an acknowledgment and rate control channels and also the new authorization timing diagram of an exemplary embodiment having a combination. 请求、授权、子数据包传输(未被正确解码)和NAK的传输与图10所示的前8个帧相同。 Request, authorization, subpacket transmission (not decoded correctly) and the front frame 8 shown in FIG. 10 NAK transmission and the same. 在该示例中,第二个子数据包传输也被正确接收和接收。 In this example, the second sub-packet transmission is also received and correctly received. 但是,基站发送的不是ACK_ RC,而是发送了ACK_ST0P。 However, the base station sends not ACK_ RC, but sent ACK_ST0P. 如果ACK_ST0P未伴随有授权,则移动站将回到自动传输。 If not accompanied by ACK_ST0P authorized, the mobile station will return to the automatic transmission. 但相反的是,发送了一个新的授权。 But the contrary is sent a new authorization. 移动站在该帧内不必监视F-RCCH。 The mobile station need not monitor frame F-RCCH. 然后,移动站根据该新授权,发送下一数据包的第一子数据包。 Then, the mobile station in accordance with the new grant, transmitting a first subpacket of the next packet.

[0201] 图12是一个具有组合的确认和速率控制信道、但却没有授权的示例性实施例的时序图。 [0201] FIG. 12 is a combination of a acknowledgment and rate control channels, but no timing view of an exemplary embodiment of the authorization. 该示例与图10基本相同,不同之处在于:不发送授权,以响应原始移动站请求。 This example is substantially the same as FIG. 10, except that: no transmission authorization in response to the original mobile station request. 因此,以自动速率发送第一数据包的第一子数据包传输。 Therefore, the transmission of the first sub-packet transmission of the first data packet to automatically rate. 在基站中,该子数据包也被正确解码。 In the base station, the sub-packets are not correctly decoded. 第二个子数据包也被正确解码,并且,ACK_RC与速率控制命令一起发送。 The second sub-packets are not correctly decoded, and, ACK_RC transmitted together with the rate control command. 然后,移动站以潜在调整后的速率,发送下一数据包。 Then, the mobile station potentially adjusted rate after sending the next packet. 该示例说明,可以只使用速率控制命令而不使用授权,随意地改变移动站速率。 This example shows, only a rate control command may be used instead of using the authorization, the mobile station rate arbitrarily changed.

[0202] 应当注意的是,在其他实施例中,在有或没有前一请求的情况下,移动站可以使用速率控制和自动传输。 [0202] It should be noted that, in other embodiments, with or without a previous request, the mobile station may use rate control and automatic transmission. 简约可用于减轻拥塞,当有额外容量时,可以增速,即便BS不知道数据需求,因为没有发送请求。 Simple may be used to reduce congestion, when there is extra capacity, the growth rate may even BS does not know the data requirements, since there is no transmission request.

[0203] 应当注意的是,在上述所有实施例中,在不偏离本发明的保护范围的前提下,方法步骤可以互换。 [0203] It should be noted that in all the above embodiments, without departing from the scope of the present invention, the method steps may be interchanged. 这里的描述在很多情况下提及与IxEV-DV系统相关联的信号、参数和过程, 但本发明的保护范围不限于此。 Described herein refer to signals, parameters, and procedures associated with the IxEV-DV system, in many cases, although the scope of the present invention is not limited thereto. 本领域技术人员可以很容易地将这里的原理运用到各种其他通信系统中。 Those skilled in the art can easily use the principles herein to various other communication systems. 对于本领域技术人员来说,这些和其他修改将是显而易见的。 For skilled in the art, these and other modifications will be apparent.
