领域 field

揭示的实施例一般涉及无线通信,尤其涉及带有可变数据传输速率的通信系统内的反向链路速率调度。 The disclosed embodiments relate generally to wireless communications, and particularly to reverse link rate scheduling in a communication system with variable data transmission rate.

背景 background

通信领域有许多应用,包括例如寻呼、无线本地环路、互联网电话以及卫星通信系统。 Field of communications has many applications including, e.g., paging, wireless local loops, Internet telephony, and satellite communication systems. 示例应用是用于移动订户的蜂窝电话系统。 Example application is cellular telephone systems for mobile subscribers. (如在此使用的,"蜂窝"系统一词包括蜂窝和个人通信服务(PCS)系统频率)。 (As used herein, "cell" used herein includes cellular systems and personal communication services (PCS) system frequencies). 己经为该种蜂窝系统研发了设计成允许多个用户接入的现代通信系统。 Cellular systems have been developed for this kind of modern communication systems designed to allow multiple users to access. 这些现代通信系统可以基于码分多址(CDMA)、时分多址(TDMA)、频分多址(FDMA)、空分多址(SDMA)、 极分多址(PDMA)或其他领域内已知的调制技术。 These modern communication systems may be based on the known code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), space division multiple access (SDMA), polarization division multiple access (the PDMA), or other areas modulation techniques. 这些调制技术对从通信系统的多个用户接收到的信号解调,从而增加通信系统容量。 These modulation techniques received from a plurality of user communication system according to the demodulated signal, thereby increasing the capacity of the communication system. 与此相关,已经建立了各种无线系统,包括例如高级移动电话服务(AMPS)、全球移动通信系统(GSM) 和一些其他无线系统。 Related to this, various wireless systems have been established, including for example, Advanced Mobile Phone Service (AMPS), Global System for Mobile Communications (GSM), and other wireless systems.

在FDMA系统内,总频谱被分成多个更小的子频带,且每个用户被给予其自己的子带以接入通信媒质。 In FDMA systems, the total frequency spectrum is divided into a plurality of smaller sub-bands and each user is given its own sub-band to access the communication medium. 或者在TDMA系统内,每个用户在周期性连续时隙内被给予整个频谱。 Or in the TDMA system, each user is given the entire frequency spectrum in the consecutive time slots periodically. CDMA系统提供优于其他类型系统的潜在优势,包括增加的系统容量。 CDMA systems offer advantages over other types of systems of potential advantages, including increased system capacity. 在CDMA系统内,每个用户在所有时间被给予整个频谱,但通过使用唯一码区别其传输。 In a CDMA system, each user is given the entire frequency spectrum all the time, but the difference by using the unique code its transmission.

CDMA系统可能设计成支持一个或多个CDMA标准诸如(1) "TIA/EIA—95 —B Mobile Station-Base Station Compatibility Standard for Dual-Mode Wideband Spread Spectrum Cellular System" (IS-95标准);(2)由名为"第三代合作人计划"(3GPP)的联盟提供的标准,它们体现在一组文档内,包括文档号3G TS 25.211、 3G TS 25.212、 3G TS 25.213以及3G TS 25.214 (W一CDMA标准);(3)由名为"第三代合作人计划2" (3GPP2)的联盟提供的标准,它们体现在"TR-45.5 Physical Layer Standard for cdma2000 Spread Spectrum Systems" (IS-2000标准)内以及(4) 一些其它标准。 A CDMA system may be designed to support one or more CDMA standards such as (1) "TIA / EIA-95 -B Mobile Station-Base Station Compatibility Standard for Dual-Mode Wideband Spread Spectrum Cellular System" (IS-95 standard); (2 ) standard provided by the alliance called "third generation partner program" (3GPP), which are reflected in a set of documents, including documents No. 3G TS 25.211, 3G TS 25.212, 3G TS 25.213 and 3G TS 25.214 (W a CDMA standard); (3) by a consortium named "3rd Generation partnership Project 2 people" standard (3GPP2) of the Union, which are embodied in "TR-45.5 Physical Layer standard for cdma2000 Spread Spectrum Systems" (iS-2000 standard) and the inner (4) some other standards.

在上述的CDMA通信系统和标准内,可用频谱同时在多个用户间共享,且可以使用诸如切换的技术以维持足够支持诸如语音的延时敏感服务的质量。 In said CDMA communication systems and standards, the available spectrum shared among multiple users simultaneously, such as switching technology and can be used to maintain sufficient quality to support delay-sensitive services such as voice is. 数据服务也可用。 Data services are also available. 最近,提出了通过使用更高阶调制、非常快速调度以及对有更宽松延时要求的服务调度的增强数据服务容量的系统。 Recently proposed by using higher order modulation, very fast scheduling and enhanced data service capacity of the service scheduled to have a more relaxed latency requirements of the system. 该种使用这些技术只有数据通信系统示例是符合TIA/EIA/IS-856标准的高数据速率(HDR)系统(IS-856标准)。 The kinds of these techniques only exemplary data communication system is consistent with TIA / EIA / IS-856 standard high data rate (HDR) system (IS-856 standard).

与上述标准相比,IS-856系统使用每个小区内所有可用频谱以将数据每次发送到单个用户。 Compared to the above standard, IS-856 system uses all of the available spectrum in each cell to transmit data to each individual user. 一个确定服务哪个用户的因数是链路质量。 A service to determine which users are link quality factor. 通过使用链路质量作为选择哪个用户被服务的因数,当信道较佳时,系统花更大比例的时间以更高的速率发送数据,因此避免了牺牲资源在低效速率的传输上。 By using link quality as a factor which services the user is selected, when the preferred channel, the system spend a greater percentage of time sending data at higher rates, thus avoiding the inefficient transfer rate at the expense of resources. 净效应是更高的数据容量、更高的峰值数据速率以及更高的平均吞吐量。 The net effect is higher data capacity, higher peak data rates, and higher average throughput.

系统可以包括对延时敏感数据的支持,诸如在IS-2000标准内支持的语音信道或数据信道,连同对诸如在IS-856标准内描述的对分组数据服务的支持。 The system may include support for delay-sensitive data, such as support in the IS-2000 standard voice channel or a data channel, together with the support such as in the IS-856 standard describes the packet data services. 一种该种系统在LG电子、LSI逻辑、朗讯科技、Nortel网络、高通公司以及三星向第三代合伙人计划2 (3GPP2)提出。 One such kind of system in LG Electronics, LSI Logic, Lucent Technologies, Nortel networks, Qualcomm and Samsung plan to the Third Generation Partnership 2 (3GPP2) proposed. 该提议在以下文档中详细描述: "Updated Joint Physical Layer Proposal for lxEV—DV",向3GPP2在2001 年6月11日作为文档号C50-20010611-009提交;"Results of L3NQS Simulation Study",向3GPP2在2001年8月20日作为文档号C50-20010820-Oil提交;以及"System Simulation Results for the L3NQS Framework Proposal for cdma2000 lx-EVDV", 向3GPP2在2001年8月20 日作为文档号C50-20010820-012提交。 The proposal is described in detail in the following documents: "Updated Joint Physical Layer Proposal for lxEV-DV", submitted in 2001 to 11 June 3GPP2 as document number C50-20010611-009; "Results of L3NQS Simulation Study", the 3GPP2 filed August 20, 2001 as document number C50-20010820-Oil; and "System Simulation Results for the L3NQS Framework Proposal for cdma2000 lx-EVDV", 3GPP2 2001 to August 20 as the document number C50-20010820- 012 submitted. 这些在此后被称为lxEV-DV提议。 These hereinafter referred to lxEV-DV proposal.

详细描述 Detailed Description

"示例"一词在此仅用于指"作为示例、实例或说明"。 Word "exemplary" is used herein only means "serving as an example, instance, or illustration." 任何在此作为"示例"描述的实施例不一定被理解为最优或优于其他实施例的。 Any herein "exemplary" is not necessarily to be described in Example understood as an optimal or advantageous over other embodiments.

一无线通信系统可以包括多个移动站和多个基站。 The wireless communication system may include a plurality of mobile stations and a plurality of base stations. 图l是带有三个移动站IOA、 IOB和10C以及两个基站12的无线通信系统实施例。 Figure l is with three mobile stations IOA, IOB, and a wireless communication system 10C and two base stations 12 in the embodiment. 在图1内,三个基站被示出为安装在车10A内的移动电话单元、可携带计算机远程IOB和固定定位单元IOC,诸如可能在无线本地环路或里程读取系统内找到的。 In FIG. 1, three base stations are shown as a mobile telephone unit installed in a car 10A, a portable computer remote unit IOB and fixed positioning the IOC, such as might be found in a wireless local loop or mileage reading system. 移动站可以是任何类型的通信单元,诸如例如手持个人通信系统单元、如个人数字助理的可携带数据单元或诸如里程读取设备的固定定位数据单元。 The mobile station may be any type of communication unit such as a personal communication system such as a handheld unit, such as a personal digital assistant may carry data or fixed location data units such as a unit mileage reading apparatus. 图1示出从基站12 到移动站10的前向链路14和从移动站10到基站12的反向链路16。 Figure 1 shows a forward link 14 and reverse link 16 from the mobile station 10 to base station 12 from the base stations 12 to the mobile station 10.

随着移动站在物理环境内移动,在移动站处接收到的以及在基站处接收到的这些路径上的信号路径数和信号强度一直改变。 As the mobile station moves within a physical environment, the received signal at the mobile station and the number of paths and the signal strength on these paths received at the base station has been changed. 因此,实施例内的接收机使用被称为搜索器元件的特定处理元件,它连续在时域内搜索信道以确定多径环境内信号的存在、时偏和信号强度。 Thus, in the embodiment of a receiver using a specific embodiment of the processing element called a searcher element, that the continuous channel region when searching the channel for the presence of the multipath signal environment, the signal strength and timing offset. 搜索器元件还被称为搜索器引擎。 The searcher element is also called a search engine. 搜索器元件的输出提供了用于保证解调元件跟踪最佳路径的信息。 The output of the searcher element provides the information for ensuring the demodulation elements to track the best path.

当多个移动同时发送时,来自一个移动的无线电传输是对其他移动的无线电传输的干扰,从而限制了反向链路(又被称为上行链路)上可获得的吞吐量。 When a plurality of mobile transmitting simultaneously, the radio transmission from one mobile interference to other mobile radio transmission, thereby limiting the reverse link (also called the uplink) on the available throughput. 为了反向链路上的有效容量利用,基站处的集中调度在美国第5914950号专利以及美国第5923650号专利内被推荐,前者题为"METHOD AND APPARATUS FOR REVERSE LINK RATE SCHEDULING",发布于1999年6月22日,后者题为"METHOD AND APPARATUS FOR REVERSE LINK RATE SCHEDULING",提交于1999年6月13日,两者都被转让给本发明的受让人。 To reverse the effective use of capacity on the link, centralized scheduling at the base station United States Patent No. 5,914,950 and is recommended in US Patent No. 5,923,650, the former entitled "METHOD AND APPARATUS FOR REVERSE LINK RATE SCHEDULING", released in 1999 June 22, which is entitled "METHOD AND APPARATUS fOR REVERSE LINK RATE SCHEDULING", filed on June 13, 1999, both assigned to the assignee of the present invention.

在示例实施例内,实现多级调度。 In the exemplary embodiment embodiment, multi-level scheduling. 在一实施例中,多级调度包括基站层调度、选择器层调度和/或网络层调度。 In one embodiment, multi-level scheduling comprises base station level scheduling, selector level scheduling, and / or network level scheduling.

在一实施例中,灵活的调度算法详细设计基于限制反向链路系统容量的基本理论原理,而同时使用基站可用或测量的现存网络参数。 In one embodiment, a detailed design of a flexible scheduling algorithm is based on fundamental theoretical principles limit the reverse link system capacity, while using existing network parameters available or measured by a base station.

在一实施例中,给定当前传输速率情况下,每个移动的容量影响的基站估计基于测量的信噪比(Snr)或导频对噪声加干扰比(Ecp/(Io+No)), 一起被称为(Ecp/Nt)。 In one embodiment, given the current transmission rate, the base station for each mobile impact capacity estimated based on the measured signal to noise ratio (Snr) or pilot to the noise plus interference ratio (Ecp / (Io + No)), together referred to (Ecp / Nt). 多径情况下来自所有指的导频Ecp/Nt测量在美国第10/011519 号申请内揭示,题为"METHOD AND APPARATUS FOR DETERMINING REVERSE LINK LOAD LEVEL FOR REVERSE LINK DATA RATE SCHEDULING IN A CDMA COMMUNICATIONSYSTEM",提交于2001年11月5日,且被转让给本发明受让人。 Multipath refers to the pilots from all Ecp / Nt measurement in U.S. Application No. 10/011519 discloses, entitled "METHOD AND APPARATUS FOR DETERMINING REVERSE LINK LOAD LEVEL FOR REVERSE LINK DATA RATE SCHEDULING IN A CDMA COMMUNICATIONSYSTEM", submitted on November 5, 2001, and assigned to the assignee of the present invention.

从不同信道上的当前速率处的导频Ecp/Nt测量,在这些信道上新速率处估计移动的容量影响。 Conducting pilot Ecp from the current rate at different channels / Nt measurement, the effect of moving the estimated capacity of these channels at the new rate.

在一实施例中,优先化对速率分配的移动请求。 In an embodiment, mobile requests for rate prioritized allocation. 调度器负责调度的所有移动列表取决于调度实现哪一层而维持。 A list of all mobile scheduler responsible for scheduling depends on which level the scheduling realize maintained. 在一实施例中,有一张对所有移动的列表。 In one embodiment, there is a list of all movement. 或者,对于所有移动有两张列表。 Alternatively, there are two lists for all mobile. 如果调度器负责调度所有移动站在其活动集合内有的基站,则移动站属于第一列表。 If the scheduler is responsible for scheduling all the base stations within the mobile station and some of its active set, the mobile station belongs to the first list. 可以为以下一种基站维持分离第二列表,即所述移动在其活动集合内有调度器不负责调度的基站。 Separating the second list may be maintained for the following base station, i.e. the mobile station is responsible for scheduling the scheduling is not in its active set. 移动速率请求的优先级化基于最大化系统吞吐量而同时允许移动公平性以及其重要性状态的各种报告、测量或已知参数。 Rate of movement of priority of the request based on various reports of maximizing system throughput while allowing the mobile fairness as well as their importance status, measured or known parameters.

在实施例内,使用Greedy填充(Greedy filling)。 In the embodiment, a Greedy filling (Greedy filling). 在Greedy填充内, 更高优先级的移动获得可用扇区容量。 Greedy filling in the higher priority mobile obtain a usable sector capacity. 可以被分配的最高速率被确定为移动可以在此速率发送的最高速率。 Highest rate that can be allocated is determined as the highest rate that can be transmitted in this movement rate. 在一实施例中,最高速率基于测量的SNR确定。 In one embodiment, the highest rate is determined based on the measured SNR. 在一实施例中,最高速率基于Ecp/Nt而确定。 In one embodiment, the maximum rate based on Ecp / Nt is determined. 在一实施例中,最高速率还基于限制参数而确定。 In one embodiment, the highest rate is also determined based on the limit parameters. 在一实施例中,最高速率由移动的缓冲器估计而确定。 In one embodiment, the highest rate is determined by the movement of the estimated buffer. 高速率的选择减少了传输延时并减少了发送移动受到的干扰。 Selects a high rate to reduce the transmission delay and the transmission reduces interference received by the mobile. 剩余扇区容量可以被分配给下一更低优先级移动。 The remaining sector capacity can be allocated to the next lower priority mobile. 该方法帮助最大化了由于干扰减少形成的增益,而同时最大化容量利用。 This approach helps maximize the gain reduction due to the interference formed, while maximizing the capacity utilization.

通过选择不同的优先级化函数,Greedy填充算法取决于规定的填充算法可以被调谐到常规循环、按比例公平或最不公平调度。 By selecting different prioritization functions, the Greedy filling algorithm depending on a predetermined filling algorithm may be tuned to the conventional cycle, proportionally fair or most unfair scheduling. 在考虑的调度类之下,上述方法帮助最大化容量利用。 Scheduling class under consideration, the above method helps maximize capacity utilization.

移动站通过将请求消息发送到基站而初始呼叫。 The mobile station by the base station sends a request message to the original call. 一旦移动从基站接收到信道分配消息,它可以使用逻辑专用信道用于进一步与基站通信。 Once the mobile station assignment message received from the channel, it can use logical dedicated channel for further communication with the base station. 在调度的系统内,当基站有数据要发送时,它可以通过在反向链路上发送请求消息而初始反向链路上的高速数据传输。 Within the scheduling system, when the base station has data to transmit, it can send a request message on the reverse link and the initial high-speed data transmission on the reverse link.

考虑当前在IS 2000版本C内规定的速率请求和速率分配结构。 Regardless of the current version specified in IS 2000 C the rate request and rate allocation structure. 然而,对于领域内技术人员设计范围很明显不限于IS 2000。 However, for the skilled person to design a range not apparent IS 2000. 对于领域内技术人员很明显的是实施例可以在任何带有速率分配集中调度器的多个接入系统内实现。 For the skilled person it is obvious that the embodiments may be implemented with any centralized scheduler rate assignment multiple access system.

不连续传输和可变辅助调整增益:MS可以由调度器在每个调度时段内被分配以R-SCH速率。 Discontinuous transmission and the auxiliary variable gain adjustments: MS may be assigned R-SCH rate by a scheduler during each scheduling period. 当MS不被分配以R-SCH速率时,它不在R-SCH上不进行发送。 When the MS is not allocated to R-SCH rate, it does not transmit on the R-SCH. 如果MS被分配以在R-SCH上发送,但它没有任何数据或充分功率以在分配的速率处发送,则它禁用在R-SCH上的传输(DTX)。 If the MS is assigned to transmit on the R-SCH, but it does not have any data or sufficient power to transmit at the assigned rate, it disables transmission on the R-SCH (DTX). 如果系统允许,MS可以在R-SCH上以低于分配的速率自动发送。 If the system allows, MS can automatically send a rate lower than the assigned on the R-SCH. 在一实施例中,该可变速率R-SCH 操作是由可变速率SCH增益调整伴随的,所述调整如TIA/EIA-IS-2000. 2内规定的。 In one embodiment, the variable rate R-SCH operation is accompanied by the variable rate SCH gain adjustment, and the adjustment / within a predetermined 2. A TIA-2000 EIA-IS is. 假设接收到的导频SNR高到足以支持R-SCH上分配的速率而调整R-FCH T/P。 Assuming the received pilot SNR is high enough to support the assigned rate on R-SCH to adjust the R-FCH T / P.

R-CQICH和其他控制信道的开销传输:只有数据的MS以CQICH对导频(或控制对导频)(C/P)比在CQICH和/或其他控制信道上发送额外功率,其多信道增益调整的实现是为了维持R-CQICH(或控制信道)正确的传输功率。 Transmission overhead R-CQICH and other control channels: MS data only to pilot CQICH (or control-to-pilot) (C / P) ratio of additional transmit power or CQICH and / or other control channels that multichannel gain adjustment is implemented in order to maintain R-CQICH (or control channels) the correct transmission power. (C/P) 值对于软切换内的MS可能不同于不在软切换的MS。 (C / P) value to the MS in soft handoff may be different from the MS is not in soft handoff. (C/P)表示无多信道增益调整下控制信道使用的总功率对导频功率比。 (C / P) represents the total power without multichannel gain adjustment of the guide channel using pilot power ratio.

闭环功率控制(PC)指令:在一实施例中,MS以800 Hz速率从MS的活动集合内的所有基站(BS)接收每功率控制组(PCG) —个PC指令。 Closed Loop Power Control (PC) command: In an embodiment, the receiving MS was 800 Hz, a rate of each power control group (PCG) from all base stations (BS) in the active set of MS - a PC instruction. PCG在反向话务信道和反向导频信道上是1.25毫秒间隙。 PCG reverse traffic channel and reverse pilot channel is 1.25 milliseconds gap. 在组合来自位于一处的BS (给定小区内的扇区)的PC指令后,导频功率基于"Or-of-Downs"准则更新+ — l分贝。 After the combination of PC commands from co-located BS (a sector in a given cell), the pilot power based on the "Or-of-Downs" Guidelines Update + - l dB.

速率请求用两种方法的一种完成。 Rate request is completed in one of two methods. 在第一方法内,速率请求使用如TIA/EIA-IS-2000. 5内规定的5毫秒R-FCH上的辅助信道请求迷你消息(SCRMM) 实现。 In the first method, rate request on a supplemental channel R-FCH 5 ms as specified in the TIA / EIA-IS-2000. 5 Request Mini Message (SCRMM) implementation.

5毫秒R-FCH上的辅助信道请求迷你消息(SCRMM):在一实施例中,每个SCRMM传输是24比特(或48比特,带有9. 6 kbps处每个5毫秒FCH帧内的物理层帧开销)。 5 ms supplemental channel request on the R-FCH mini message (SCRMM): In one embodiment, each SCRMM transmission is 24 bits (or 48 bits, with each 5-ms FCH physical frame at 9. 6 kbps layer frame overhead).

MS在5毫秒的任何周期间隙内发送SCRMM。 MS transmission SCRMM in any periodic interval of 5 ms. 如果5毫秒SCRMM需要被发送, 则MS中断其当前20毫秒R-FCH帧的传输,取而代之在R-FCH上发送5毫秒帧。 If 5 ms SCRMM needs to be transmitted, the MS interrupts its transmission of the current 20 ms R-FCH frame, and instead 5 ms frames transmitted on R-FCH. 在发送了5毫秒帧之后,R-FCH上20毫秒时段内的任何剩余时间不被发送。 After transmitting the 5ms frame, any time remaining within the period of 20 ms R-FCH is not transmitted. 20 毫秒R-FCH的不连续传输在下一20毫秒帧的开始处被重建。 Discontinuous transmission 20 ms R-FCH is reconstructed at the beginning of the next 20 millisecond frame.

在第二方法内,速率请求使用在20毫秒R-FCH上的辅助信道请求消息(SCRM)实现。 In the second method, rate request using the 20 ms R-FCH auxiliary channel request message (the SCRM) implementation.

取决于不同的实施例,不同的信息可以在请求消息内被发送。 Depending on different embodiments, different information may be transmitted within the request message. 在IS2000 内,辅助信道请求迷你消息(SCRMM)或辅助信道请求消息(SCRM)为速率请求在反向链路上被发送。 In the IS2000, a supplemental channel request mini message (SCRMM) or a supplemental channel request message (the SCRM) is the rate request is transmitted on the reverse link.

在实施例中,以下信息可以在每个SCRM/SCRMM传输上由MS向BS报告:•最大请求速率*队列信息 In an embodiment, the following information may be reported by the MS to the BS on each SCRM / SCRMM transmission: • Maximum Queue Information request rate *

其中Pref (R)是在TIA/EIA-IS-2000. 2内的属性增益表格内规定的"导频参考电平"值,TxPiPwr(PCG》是在供电中断情况下对MS侧应用的功率限制后实际发送导频功率,且NormAvPiTx(PCGi)是标准化的平均发射导频功率。MS 在选择净空空间时可以更保守或更激进,且最大请求速率的确定取决于BS允许什么。 Where Pref (R) is defined in TIA / Attribute Gain table in. 2 2000 EIA-IS-"pilot reference level" value, TxPiPwr (PCG "is a power limitation of MS-side application of the power supply interruption after the actual transmit pilot power, and NormAvPiTx (PCGi) is the normalized average transmit pilot power headroom when selecting .MS be more conservative or more radical, and determining a maximum requested rate depending on what is allowed BS.

在一实施例中,MS通过两个以下方法的一个接收授权信息: 方法a:在5毫秒前向专用控制信道(F-DCCH)上来自BS的增强辅助信道分配迷你消息(ESCAMM),带有对规定调度持续时间的速率分配。 In one embodiment, the MS by the two following methods of receiving authorization information a: method a: assignment mini message (ESCAMM) Enhanced supplemental channel from the BS on the forward dedicated control channel (F-DCCH) in the first 5 ms, with allocation of the provisions of rate scheduling duration.

方法b:在前向物理数据信道(F-PDCH)上来自BS的增强辅助信道分配消息(ESCAM),带有为规定调度持续时间的速率分配。 Method b: assignment message (ESCAM) to the physical data channel (F-PDCH) reinforcing the front secondary channel from the BS, with a predetermined distribution rate scheduling duration.

这些分配延时取决于回程和传输延时,且取决于为速率授权使用哪种方法而不同。 The delays depend on the backhaul allocation and transmission delay, and depending on which method is used for the authorization rate varies. 在调度的持续时间期间,实现以下过程- During the duration of the scheduling process to achieve the following -

*在一实施例中,其中R-FCH用于发送自动数据且对于外环路PC,如果在其缓冲内有一些数据,则MS以9600比特每秒(bps)的自主(autonomous)速率发送数据。 * In one embodiment, wherein R-FCH for transmitting data and for outer-loop automatic PC, you have some data in its buffer, the MS transmits data in an autonomous (Autonomous) rate of 9600 bits per second (bps) of . 否则,MS以1500 bps发送零R-FCH帧。 Otherwise, MS sends a zero R-FCH frame at 1500 bps. *如果MS有可以在R-FCH上被携带的更多的数据且如果MS决定它会有充分功率以在分配的速率发送(保持为信道变化的净空空间),则MS在给定的20毫秒时段内以分配的R-SCH速率发送。 * If the MS has more data can be carried on R-FCH and if the MS decides that it will have sufficient power to transmit (change a channel to maintain headroom) in the rate allocation, the MS 20 milliseconds at a given in the transmission period assigned R-SCH rate. 否则,在帧期间在R-SCH上没有传输,或MS以满足功率艰制的更低速率发送。 Otherwise, there is no transmission during the frame, or in the MS R-SCH rate less difficult to meet power transmission system. 如果满足以下等式,在20毫秒时段开始之前,MS决定它有充分功率在给定20;秒时段Encode—Delay内以分配的速率R在R-SCH上发送: If the following equation is satisfied, before the 20 msec period starts, the MS determines that there is sufficient power in a given 20; R & lt sent on the R-SCH at the assigned rate within the second period Encode-Delay:

其中Pref (R)是在TIA/EIA-IS-2000. 2内的属性增益表格内规定的"导频参考电平"值,NormAvPiTx(PCGi)是标准化的平均发射导频功率,(T/P) R 是对应速率R的话务对导频比,且所有信道速率在附录A内的额定属性增益表格内被规定为额定属性增益值,(T/P)^H是在FCH上的话务对导频比,(C/P) 是没有多信道增益调整时控制信道使用的总功率对导频功率比,Tx (max)是最大MS发送功率,且Headroom一Tx是MS保留以允许信道变化的净空空间。 Where Pref (R) is a "pilot reference level" specified in TIA / Attribute Gain table in. 2 2000 EIA-IS-value, NormAvPiTx (PCGi) is the normalized average transmit pilot power, (T / P ) R corresponding rate R of traffic to pilot ratio, and all channel rate are within a predetermined nominal attribute gain in Appendix a, the table shows the nominal attribute gain values, (T / P) ^ H is the traffic on the FCH pilot ratio, (C / P) is the total power control channel used in the absence of a gain adjustment for multi-channel pilot power ratio, Tx (max) is the maximum MS transmit power, and a Headroom Tx is reserved to allow the MS channel variation headroom.

在R-SCH传输之前,每个帧Encode_Delay PCG时完成一次DTX确定。 Before R-SCH transmission, each complete a DTX frame is determined Encode_Delay PCG. 如果MS禁用R-SCH上的传输,则它以以下功率发送: If the MS disables transmission on the R-SCH, it transmits at the following power:

l + ((r/户)^十(c/尸》 l + ((r / household) ^ ten (c / dead "

MS在实际传输前对传输帧Encode—Delay编码。 MS encodes the transmission frame Encode-Delay before the actual transmission. 基站过程 The base station process

在一实施例中,BS实现以下关键功能: * R-FCH/R-SCH的解码»功率控制R-FCH/R-SCH的解码 In one embodiment, BS realize the following key features: * R-FCH / R-SCH decoding »power control decoder R-FCH / R-SCH in

当MS同时发送多个话务信道时,每个话务信道在与对应的Walsh序列相关联后被解码。 When the MS simultaneously transmit multiple traffic channels, each traffic channel corresponding to the associated Walsh sequence after decoding. 功率控制 Power Control

CDMA系统内的功率控制对于维持期望的服务质量(QoS)是很关键的。 Power control in CDMA systems to maintain the desired quality of service (QoS) is critical. 在IS-2000内,每个MS的RL导频信道(R-PICH)是控制到期望阀值的闭环功率。 In the IS-2000, RL pilot for each MS pilot channel (R-PICH) is controlled to a desired closed loop power threshold. 在BS处,该阀值被称为功率控制设定点,与接收到的Ecp/Nt相比以生成功率控制指令(闭环PC),其中Ecp是每码片导频信道能量。 At the BS, this threshold value is called a power control set point, the received Ecp / Nt to generate power control command compared (closed-loop PC), where Ecp per pilot channel chip energy. 为了在话务信道上获得期望的QoS,则BS处的阀值随着话务信道上的擦除改变,且当数据速率改变时必须要调整。 In order to obtain the desired QoS on the traffic channel, the threshold at the BS is changed with the erasure of the traffic channel, and changing the data rate must be adjusted.

设定点纠正的发生是因为: Setpoint correction occurs because:

*外环路功率控制 * Outer Ring Power Control

*速率转换外环路功率控制:如果R-FCH存在,基于R-FCH的擦除纠正功率控制设定点。 Outer loop power control rate conversion *: If R-FCH is present, based on the R-FCH erasure correction power control set point. 当MS发送数据时,如果R-FCH不存在,则基于一些控制信道或R-SCH的擦除纠正外环路PC。 When the MS transmits the data, if the R-FCH is not present, based on some control channel or R-SCH in erasure correction outer loop PC.

速率转换:在R-SCH上的不同数据速率要求反向导频信道的不同最优设定点。 Conversion rate: Different data rates on the R-SCH requires different reverse pilot channel optimum setpoints. 当数据速率在R-SCH上改变时,BS通过当前和下一R-SCH数据速率间导频参考电平(Pref(R))之差改变MS接收到的Ecp/Nt。 When data rate changes on the R-SCH, BS changes the MS's received Ecp / Nt by the current and the next R-SCH data rate between the pilot reference level (Pref (R)) difference. 在一实施例中,给定数据速率R的导频参考电平在C.S0002-C内的额定属性增益表格内规定。 Attribute within a predetermined nominal gain table in the C.S0002-C pilot reference level in one embodiment, a given data rate R. 由于闭环功率控制将接收到导频Ecp/Nt带到设定点,则BS根据下一分配的R-SCH数据速率调整外环路设定点: Since the closed loop power control received pilot Ecp / Nt to the set point, the BS to adjust the outer loop set point according to the next R-SCH data rate allocation:

如果!OR。 If! OR. w,则设定点调整超前于新R-SCH数据速率而完成「A"]PCG。 w, adjusting the set point ahead of the new R-SCH data rate complete "A"] PCG. 否则, 该调整发生在R-SCH帧边界处。 Otherwise, this adjustment occurs at the R-SCH frame boundary. 导频功率因此如图2内示出向正确电平接近, 以大致闭环的1分贝步长上升或下降。 2 pilot power thus shows the approaches the correct level approximately in 1 dB step up or down a long loop.

图2根据一实施例示出由于在R-SCH上的速率转换引起的设定点调整。 FIG 2 illustrates an embodiment because the rate set point adjustment on the R-SCH due to conversion. 图2的纵轴示出基站控制器(BSC) 202的设定点、收发基站子系统(BTS)接收机导频功率204以及移动站速率206。 FIG. 2 shows a longitudinal base station controller (BSC) 202 of the set point, base station transceiver subsystem (BTS) receiver pilot power 204, and 206 the mobile station velocity. MS速率开始时在R。 MS start rate R. 208。 208. 当R-SCH数据速率增加时,即R1〉R10 210,则设定点根据Pref (RJ —Pw (R。) 212调整。当R-SCH数据速率减少时,即R2〈R214,则设定点根据Pref (R2) -Pj) 216。 When the R-SCH data rate increases, i.e., R1> R10 210, to adjust the set point 212 (RJ -Pw (R.) according Pref. When the R-SCH data rate reduction, i.e. R2 <R214, the set point The Pref (R2) -Pj) 216.

调度器过程 The scheduler process

调度器可以与BSC或BTS或网络层内的一些元件共处一处。 Scheduler may be co-located with the BSC, or BTS or some elements within the network layer. 调度器可以与负责调度共享更低层资源的MS的每个部分是多层的。 Lower-level scheduler may share resources with each part responsible for scheduling the MS is multilayered. 例如,不在软切换(SHO) 的MS可以由BTS调度,而在SHO的MS可以由与BSC位于同处的调度器部分调度。 For example, MS is not in soft handoff (SHO) may be scheduled by the BTS while the MS in SHO may be scheduled by part of co-located with the BSC scheduler. 反向链路容量为了调度目的在BTS和BSC间被分配。 For purposes of scheduling reverse link capacity is distributed between BTS and BSC.

在一实施例中,根据实施例为调度以及与调度相关的各个参数使用以下假 In one embodiment, the following assumptions is used and various parameters associated with scheduling in accordance with an embodiment scheduling

设: Assume:

1. 集中调度:调度器与BSC位于同处,且负责跨越多个小区的MS的同时调度。 1. Centralized Scheduling: The scheduler co-located with the BSC, and is responsible for MS simultaneously across a plurality of cells schedule.

2. 同步调度:所有R-SCH数据速率传输是时间对齐的。 2. Synchronous Scheduling: All R-SCH data rate transmissions are time aligned. 所有数据速率分配是针对一个调度时段的持续时间的,该时段对于系统内的所有MS时间对齐。 All data rate assignments are for the duration of one scheduling period, which time period is aligned for all MS in the system. 调度持续时间时段被标记为SCH一PRD。 Scheduling duration period is labeled as a SCH PRD.

143. 语音和自主R-SCH传输:在通过速率分配将容量分配到R-SCH上传输之前,调度器察看来自MS的未决速率请求并不理会在给定小区内的语音和自主传输。 143. Voice and Autonomous R-SCH transmissions: Before allocating capacity to transmissions on R-SCH through rate assignment, the scheduler view pending rate requests from the MS does not care about the voice and autonomous transmissions in a given cell.

4. 速率请求延时:通过SCRM/SCRMM的速率请求相关的上行链路请求延时被标记为0_既(请求)。 4. Rate Request Delay: delay request is marked both 0_ (request) throughput rate SCRM / SCRMM request related to the uplink. 它是当请求对调度器可用时发送请求的时间起的延时。 It is available when the time delay to the transmission request from a scheduler request.

5. 速率分配延时:通过ESCAM/ESCAMM的速率分配相关联的下行链路分配延时被标记为D—FL (分配)。 The rate allocation Delay: delay is marked as D-FL (allocation) allocated downlink allocation associated throughput rate ESCAM / ESCAMM is. 它是进行速率决定和MS接收产生的分配间的时间。 It is the rate determining a reception time between the MS and the generated distribution. D—FL(分配)包括从调度器到小区的回程延时、 分配(基于选择的方法)的空中传输时间以及在它在MS处的解码时间。 D-FL (allocated) from the scheduler comprises a backhaul delay cell, assignment (based on method chosen), and air transmission time in its decode time at the MS.

6. 可用Ecp/Nt测量:用于调度器的Ecp/Nt测量应是在最后帧边界处最近可用的测量。 6. Available Ecp / Nt Measurement: for Ecp / Nt measurement scheduler shall be the latest available measurements last frame boundary. 测量的Ecp/Nt由BTS接收机周期性地被报告给调度器,因此它对于BSC接收机被延时。 Ecp / Nt measurement is reported periodically to the scheduler by the BTS receiver, so it is delayed for a BSC receiver.

图3示出根据实施例的调度延时时序。 Figure 3 shows scheduling delay timing in accordance with an embodiment. 示出的数字是可以由位于BSC储的调度器使用的典型数字示例,虽然实际数字取决于回程延时和系统的负载情况。 The numbers shown are an example can be used by a typical digital BSC located scheduler reservoir, although the actual number depends on load conditions, and backhaul delay system.

横轴示出SCH帧边界250,这是在点A 252、点A254、调度时间256和行动时间258之前的最后SCH帧边界。 The horizontal axis shows the SCH frame boundary 250, which is at point A 252, point A254, last SCH frame boundary 258 before the scheduled time 256 and operations time.

调度、速率分配和传输时间线 Scheduling, rate allocation and transmission timeline

给定假设的同步调度,许多与请求、授权和传输相关的事件周期为时段SCH一PRD。 Given hypothesis synchronous scheduling, many associated with the request, authorization and transmission interval to a period SCH PRD.

图4根据一实施例说明速率请求、调度和速率分配时序图。 According to FIG 4 illustrates an embodiment of a rate request, scheduling and rate allocation timing chart. 纵轴示出BSC(调度器)402和移动404的时间线。 The vertical axis shows the BSC (scheduler) 402 and move the time line 404. MS建立SCRMM 406并将速率请求发送到BSC (调度器)408。 MS establishes SCRMM 406 and a rate request to the BSC (scheduler) 408. 速率请求被包括在SCRMM内,它在R-FCH上被发送。 Rate request is included in the SCRMM, which is sent on R-FCH. 通过SCRM/SCRMM与速率请求相关联的上行链路请求延时被标记为D—RL(请求)410。 Uplink request by the associated request SCRM / SCRMM rate and delay are labeled D-RL (request) 410. 调度决定412每个调度周期414进行一次。 Scheduling decision 412 414 once every scheduling period. 在调度决定412之后,ESCAM/ESCAMM 416在前向信道上从BSC发送到MS,指明速率分配418。 After the scheduling decision 412, ESCAM / ESCAMM 416 transmits forward channel from the BSC to the MS, indicating rate allocation 418. D_FL 420是通过ESCAM/ESCAMM与速率分配相关联的下行链路分配延时。 D_FL 420 is the downlink assignment delay associated with distribution by ESCAM / ESCAMM and rate. 转换时间422是转换速率请求需要的时间。 Conversion rate request time 422 is the time required for the conversion. 它是从速率请求到速率分配的时间。 It is the time from the rate request to rate assignment.

以下是时间线特征: The following is a timeline feature:

*调度定时 Scheduling Timing *

*调度速率传输 * Scheduled transmission rate

* MS R-SCH速率请求 * MS R-SCH Rate Request

调度定时:调度器每调度时段操作一次。 Scheduling Timing: The scheduler operated once per scheduling period. 如果第一调度决定在ti处实现, 则调度器在ti、 ti+SCH—PRD、 ti + 2SCH—PRD…处操作。 If the first scheduling decision implemented at ti, then the scheduler operates at ti, ti + SCH-PRD, ti + 2SCH-PRD ... at.

调度速率传输:由于需要充分时间才能通知MS调度决定,调度决定必须在ESCAM/ESCA醒消息的行动时间减去固定延时ActionTimeDelay处到达。 Scheduling rate transmission: because of the need sufficient time to inform the MS scheduling decisions, scheduling decisions must be subtracted to arrive at a fixed delay ActionTimeDelay action time ESCAM / ESCA wake up message. 方法a和方法b的ActionTimeDelay的一般值在表格1内给出。 Typical values ​​of ActionTimeDelay method and a method for b is given in table 1.

MS R-SCH速率请求:R-SCH速率请求如以下给出被触发: MS R-SCH Rate Request: R-SCH rate requests are triggered as given below:

在每个SCRM/SCRMM帧编码边界开始之前,MS检查是否满足以下三个条件的任意一个: Any one before each SCRM / SCRMM frame encode boundary starts, the MS checks whether the following three conditions are met:

1. 新数据到达,且MS缓冲器内的数据超过一定缓冲器深度 1. New data arrives and data in the MS's buffer exceeds a certain buffer depth

"当前分配速率"是可应用于当前速率传输的分配速率。 "Currently assigned rate" may be applied to the current rate of the transmission rate assigned. 如果对于当前调度持续时间没有接收到ESCAM,则分配的速率被认为是O。 If for the current scheduled duration is not received ESCAM, the dispensing rate is considered is O. 行动时间在一些时间之后且在ESCAM/ESCAMM消息内分配的速率在行动时间之后生效。 Time for action and enter into force after some time in the distribution rate in the ESCAM / ESCAMM message after action time.

调度器描述和过程 Scheduler Description and Procedures

在一实施例中,对于大量小区有一个集中调度器元件。 In one embodiment, there is a large number of cells for the centralized scheduler element. 调度器维持系统内所有MS列表以及每个MS的活动集合内的BS。 Scheduler maintains a list of all MS and each BS in the active set of the MS in the system. 与每个MS相关的调度器存储MS 队列大小估计(^)以及最大调度速率(Rmax(s))。 Associated with each MS MS scheduler storage queue size estimate (^) and maximum scheduled rate (Rmax (s)).

If the mobile periodically reports such as the pilot power transmitted from the request message SCRM, the propagation loss from the measurement rate priority function based on the received pilots calculated or otherwise, it may be based on the intensity of FL Ecp / Nt estimate which mobile reports have better propagation loss: If the base station estimates the estimated rate of movement of the moving rate using some algorithm. , the stationary mobile is given the highest priority, and the moving speed is given the lowest priority. based on parameters of the measurement or the report of the target in the priority function is to increase the throughput of the reverse link system unfair 优先级函数。另外,优先级可以由费用度量增加或减少,所述度量通过用户注册的服务等级而确定的。除了上述之外,可以由公平因数提供一定的公平度。两种不同的公平度描述如下:按比例公平度(PF) : PF是最大请求速率对平均获得传输速率之比。因此20;^ = *"/《"〜其中i?"是请求速率,且及;^是调度器分配的平均速率。 Priority function. In addition, priority may be increased or decreased by a cost metric, the metric is determined by the registered level of service users. In addition to the above, can provide some degree of fairness by the fairness factor. Two different fairness described as follows: proportion fairness (PF): PF is the maximum request rate than the average obtained transmission rate of the thus 20; ^ = * "/" "- wherein i" is the requested rate, and and; ^ is a scheduler.? the average rate distribution. 循环公平性(RRF):循环调度试图向所有用户提供相等的传输机会。 Fairness loop (RRF): round-robin scheduling an attempt to provide equal opportunity to all transport users. 当移动进入系统时,RRF被初始为一些值,例如0。 When the mobile enters the system, of RRF is initialized to some values, such as zero. 每个调度时段时,速率不被分配给移动,RRF递增一。 Each scheduling period the rate is not allocated to the mobile, of RRF is incremented by one. 每次一速率(或请求速率)被分配给移动时,RRF 被重设为开始值0。 Each time a rate (or the requested rate) is allocated to the mobile, RRF is reset to the starting value 0. 这类似于最后调度时段内调度的移动是队列中的最后一个。 This is similar to the move schedule last scheduling period are last in the queue. 公平性可以与优先级函数一起使用以确定优先级列表内移动的优先级。 Fairness can be used together with Priority function to determine the priority list of the mobile priority. 当公平性被单独用于优先化移动时,它提供按比例公平或循环公平调度,这为反向链路提供最优吞吐量并允许全容量利用的多个传输。 When Fairness is used alone prioritized mobility, which provides circular or proportionally fair scheduling fairness, which provide the best throughput and allowing multiple reverse link transmission full capacity utilization. 在使用先前定义的优先级函数和按比例公平的不同方面的实施例可能如下确定第i个用户的优先级:w =-i--(尸。"其中被称为公平因数的参数"可以被用于在公平性和系统吞吐量进行折衷。随着"的增加,公平性变差。带有更高《的调度器具有更高的吞吐量。接着考虑一特定实施例,其中调度器在每个调度时段唤醒并基于未决速率请求进行速率分配决定。调度算法类似于以下描述的。初始化:MS速率请求被优先级化。与每个MS相关联的是优先级计数PRIORITY (优先级)。MS的PRIORITY在开始时被初始化为0。当新MS进入带有作为主扇区的扇区j的系统时,其PRI0RITY被相等地设定为mirHPi?/O/?/7^,V/使得MSi的主扇区为扇区j}1.令负载限制为Load^maxload (最大负载),以限制超过一定阀值以上的热上升过冲(overshoot)。对于校准目的,调度器会使用0. 45的最大负载值。计算由于导频 Using the priority function previously defined and proportionally fair embodiments of different aspects of the i th user may determine the following priority: w = -i - (dead "which is called fairness factor parameter" may be. for fairness and system throughput tradeoff. with the "increase fairness deteriorated. with higher" higher throughput scheduler. Next consider a particular embodiment, wherein each scheduler a scheduling period based wakeup pending rate requests allocation rate decision similar to the scheduling algorithm described below is initialized:. MS rate requests are prioritized associated with each MS is a priority count the pRIORITY (priority).
