2"(3GPP2)之組織的文獻中。此等各種無線電技術及標準 係此項技術中已知的。 為清晰起見，以下對於實施IS-856之高速率封包資料 (HRPD)系統描述該等技術之各種態樣。HRPD亦被稱作演 進資料最佳化（EV-DO)、資料最佳化（DO)、高資料速率 (HDR)等。經常可互換地使用術語"HRPD"及"EV-DO”。目 前，已標準化HRPD修訂版（Rev.)O、A及B，採用HRPD修 訂版0及A，且正在研發HRPD修訂版C。HRPD修訂版0及A 涵蓋單載波HRPD(lxHRPD)。HRPD修訂版B涵蓋多載波 HRPD且與HRPD修訂版0及A回溯相容。本文中所述之技 術可併入於任何HRPD修訂版中。為清晰起見，在大部分 以下許多描述中使用HRPD術語。 圖1展示一具有多個存取點110及多個終端機120之HRPD 通信系統100。存取點通常為與終端機通信之固定台，且 亦可被稱作基地台、節點B等。每一存取點110為一特別地 理區域提供通信覆蓋，且支援位於覆蓋區域内之終端機之 通信。存取點11 〇可耦接至一為此等存取點提供協調及控 制之系統控制器130。系統控制器130可包含諸如基地台控 制器（BSC)、封包控制功能（PCF)、封包資料伺服節點 (PDSN)等的網路實體。 終端機120可分散於整個系統中，且每一終端機可為固 定或行動終端機。終端機亦可被稱作存取終端機、行動 台、使用者裝備（user equipment)、用戶單元、台等。終端 機可為蜂巢式電話、個人數位助理（PDA)、無線設備 118974.doc Y ⑻deV1Ce)、掌上型設備、無線數據機、膝上型電腦 等、、端機可支援任何抓⑽修訂版。在中，終端機 可在任何給;t時刻卜存取點接收前向鏈路上之傳輸，且 可在反向鏈路上將傳輸發送至―或多個存取點。前向鍵路 (或下行鏈路)係指自存取點至終端機之通信鏈路，且反向 鏈路(或上行鏈路)係指自終端機至存取點之通信鏈路。 圖2展不支援HRPD中前向鏈路上iCDM的單載波槽結 構200傳輸時間線經分割為若干個槽。每一槽具有1 gw 毫秒（ms)之持續時間且跨越2〇48個碼片。對於1 2288百萬 碼片/秒（MCps)之竭片速率，每一碼片具有8138奈秒㈣之 持續時間。每一槽經分割為兩個相同的半槽。每一半槽包 ^⑴耗用區段（overhead segment)，其包括在半槽中心 處之導頻區段（pilot segment)及在導頻區段兩側上之兩個 媒體存取控制（MAC)區段；及（丨卩兩個訊務區段，其在該耗 用區段兩側上。訊務區段亦可被稱作訊務通道區段、資料 區段、資料域等。導頻區段載運導頻且具有96碼片之持續 時間。每一 MAC區段載運信號（例如，反向功率控制（Rpc) 資訊）且具有64碼片之持續時間。每一訊務區段載運訊務 鞅料（例如，用於特又終端機之單播（unicast)資料、廣播資 料等）且具有400碼片之持續時間。 HRPD修訂版0、A及B對在訊務區段中發送之資料使用 CDM。一訊務區段可載運用於由一存取點伺服之一或多個 終端機的CDM資料。可基於編碼及調變參數來處理用於該 終端機之訊務資料以產生資料符號，該等編碼及調變參數 I18974.doc -10· 1336188 係根據自每一終端機接收到之通道反饋所確定。可解多工 用於該或該等終端機之資料符號且用16碼片之沃爾什函數 (Walsh function)或碼覆蓋該等資料符號以產生用於訊務區 段之CDM資料。因此使用沃爾什函數在時域中產生CDM 資料。CDM訊務區段係載運CDM資料之訊務區段。 可需要對在訊務區段中發送之資料使用OFDM及/或單載 波分頻多工（SC-FDM)。OFDM及SC-FDM將可用頻寬分割 為多個正交副載波，其亦被稱作音調、區間（bin)等。可用 資料來調變每一副載波。一般而言，藉由OFDM在頻域中 發送調變符號及藉由SC-FDM在時域中發送調變符號。 OFDM及SC-FDM具有某些所要的特性，諸如易於對抗由 頻率選擇性衰落引起之符號間干擾（ISI)的能力。OFDM亦 可有效地支援ΜΙΜΟ及SDMA，ΜΙΜΟ及SDMA可獨立地應 用於每一副載波上且可因此在頻率選擇通道中提供良好的 效能。為清晰起見，以下描述使用OFDM來發送資料。 可需要支援OFDM，同時保持與HRPD修訂版0、A及B之 回溯相容性。在HRPD中，導頻區段及MAC區段可在任何 時間由所有作用中終端機予以解調變，而訊務區段僅可由 被伺服之終端機予以解調變。因此，可藉由保持導頻及 MAC區段且修改訊務區段而達成回溯相容性。可藉由以具 有400碼片或更少之總持續時間的一或多個OFDM符號替換 一給定的400碼片之訊務區段中之CDM資料而在一 HRPD波 形中發送OFDM資料。 圖3A展示一支援HRPD中之OFDM之單載波槽結構300。 1 l8974.doc 11 為簡單起見，圖3A中僅展示一個半槽。該半槽包含：（i) 一 耗用區段，其包括一在半槽中心處之96碼片之導頻區段及 在該導頻區段兩側上之兩個64碼片之MAC區段；及（ii)兩 個訊務區段，其在該耗用區段兩側上。一般而言，每一訊 務區段可載運一或多個OFDM符號。在圖3A中所示之實例 中，每一訊務區段載運兩個OFDM符號，且每一OFDM符 號具有200碼片之持續時間且係在一個為200碼片之OFDM 符號週期中予以發送。 圖3B展示一支援HRPD中之CDM及OFDM之單載波槽結 構302。一半槽包含：⑴一耗用區段，其包括一 96碼片之 導頻區段及兩個64碼片之MAC區段，及（ii)兩個訊務區 段，其在該耗用區段兩側上。在一設計中，可為每一訊務 區段選擇CDM或OFDM。在此設計中，在選擇CDM時，每 一訊務區段可載運CDM資料，或在選擇OFDM時，每一訊 務區段可載運一或多個OFDM符號。在其他設計中，一訊 務區段可載運CDM資料與OFDM資料。舉例而言，一訊務 區段可在該訊務區段之一半中載運CDM資料且在該訊務區 段之另一半中載運一或多個OFDM符號。 一般而言，可基於各種OFDM符號數字學（numerology) 或設計而產生OFDM符號。每一 OFDM符號數字學與有關 的參數（諸如OFDM符號持續時間、副載波之數目、循環前 置項長度等）之特定值相關聯。OFDM符號持續時間應為 400碼片訊務區段之整數除數（integer divisor)以便充分利 用訊務區段。此外，OFDM符號之樣本速率應為CDM資料 118974.doc 12 1336188 之碼片速率的整數倍，以便簡化在存取點及終端機處之處 理。 列出用於HRPD之三個實例OFDM符號數字學。此等數 字學經選擇以與HRPD槽結構及碼片速率相容，以使得⑴ 在一訊務區段中發送整數數目之OFDM符號且（ii)OFDM符 號之樣本速率為CDM資料之碼片速率的整數倍。該等數字 學進一步經選擇以致副載波之總數目（其確定離散傅立葉 變換（DFT)大小）允許有效產生OFDM符號。對於此等數字 學，副載波之總數目並非2的冪而是具有小的質因數。舉 例而言，可以2、3、3及5之質因數獲得90個副載波。小的 質因數可允許有效的混合基數快速傅立葉變換（FFT)實施 以產生OFDM符號。 表1中所示之數字學允許在HRPD前向鏈路波形中有效嵌 入OFDM資料。 表1 參數

[Embodiment] The transmission techniques described herein are applicable to various wireless communication systems such as CDMA, TDMA, FDMA, OFDMA, and SC-FDMA systems. The terms "system" and "network" are often used interchangeably. The CDMA system can implement radio technologies such as cdma2000, Universal Terrestrial Radio Access (UTRA), Evolved UTRA (E-UTRA), and the like. Cdma2000 covers the IS-2000, IS-95, and IS-856 standards. UTRA includes Wideband CDMA (W-CDMA) and Low Chip Rate (LCR). A TDMA system can implement a radio technology such as the Global System for Mobile Communications (GSM). The OFDMA system can implement radio technologies such as Long Term Evolution (LTE), IEEE 802.20, Flash OFDM, and the like. UTRA, E-UTRA, GSM, and LTE are described in a document from an organization named "3rd Generation Partnership Project" (3GPP). Cdma2000 is described in documents from an organization named "3rd Generation Partnership Project 118974.doc 1336188 2" (3GPP2). These various radio technologies and standards are known in the art. For the sake of clarity, the following describes various aspects of such techniques for implementing the High Rate Packet Data (HRPD) system of IS-856. HRPD is also known as Evolution Data Optimization (EV-DO), Data Optimization (DO), and High Data Rate (HDR). The terms "HRPD" and "EV-DO" are often used interchangeably. Currently, HRPD revisions (Rev.) O, A and B have been standardized, HRPD revisions 0 and A have been adopted, and HRPD revision C is being developed. HRPD Revisions 0 and A cover single-carrier HRPD (lxHRPD). HRPD Revision B covers multi-carrier HRPD and is compatible with HRPD Revision 0 and A backtracking. The techniques described herein can be incorporated into any HRPD revision. For clarity, the HRPD terminology is used in most of the following descriptions. Figure 1 shows an HRPD communication system 100 having multiple access points 110 and a plurality of terminals 120. The access point is typically in communication with the terminal. Fixed stations, and may also be referred to as base stations, Node B, etc. Each access point 110 provides communication coverage for a particular geographic area and supports communication of terminals located within the coverage area. Access point 11 Connected to a system controller 130 that provides coordination and control for such access points. System controller 130 may include, for example, a base station controller (BSC), a packet control function (PCF), a packet data servo node (PDSN), and the like. Network entity. Terminal 120 can be dispersed throughout In the system, each terminal can be a fixed or mobile terminal. The terminal can also be called an access terminal, a mobile station, a user equipment, a subscriber unit, a station, etc. The terminal can be a hive. Telephone, personal digital assistant (PDA), wireless device 118974.doc Y (8) deV1Ce), handheld device, wireless data machine, laptop, etc., the terminal can support any scratch (10) revision. In the terminal, the terminal can The access point receives the transmission on the forward link at any time; and the transmission can be sent to the "or multiple access points" on the reverse link. The forward key (or downlink) refers to Access point to the communication link of the terminal, and the reverse link (or uplink) refers to the communication link from the terminal to the access point. Figure 2 does not support the iCDM single on the forward link in HRPD The carrier slot structure 200 transmission timeline is divided into slots. Each slot has a duration of 1 gw milliseconds (ms) and spans 2 〇 48 chips. For 1 2288 million chips per second (MCps) The chip rate, each chip has a duration of 8138 nanoseconds (four). It is two identical half slots. Each half slot contains (1) an overhead segment, which includes a pilot segment at the center of the half slot and two on both sides of the pilot segment. Media access control (MAC) segments; and (two traffic segments, which are on either side of the consumption segment. The traffic segment may also be referred to as a traffic channel segment, a data region Segment, data field, etc. The pilot segment carries the pilot and has a duration of 96 chips. Each MAC segment carries a signal (e.g., reverse power control (Rpc) information) and has a duration of 64 chips. Each traffic segment carries traffic information (e.g., unicast data for broadcasts, terminal broadcasts, etc.) and has a duration of 400 chips. HRPD Revisions 0, A, and B use CDM for materials sent in the Traffic Zone. A traffic segment can carry CDM data for one or more terminals served by an access point. The data symbols for the terminal can be processed based on the encoding and modulation parameters to generate data symbols. The encoding and modulation parameters I18974.doc -10· 1336188 are based on the channel feedback received from each terminal. determine. The multiplexable data symbol for the terminal or the terminals is overwritten with a 16-chip Walsh function or code to generate CDM data for the traffic segment. Therefore, the Walsh function is used to generate CDM data in the time domain. The CDM Traffic Zone is the traffic section that carries CDM data. It may be desirable to use OFDM and/or Single Carrier Frequency Division Multiplexing (SC-FDM) for data transmitted in the traffic section. OFDM and SC-FDM partition the available bandwidth into a plurality of orthogonal subcarriers, which are also referred to as tones, bins, and the like. The data can be used to modulate each subcarrier. In general, modulation symbols are transmitted in the frequency domain by OFDM and modulated symbols are transmitted in the time domain by SC-FDM. OFDM and SC-FDM have certain desirable characteristics, such as the ability to easily combat inter-symbol interference (ISI) caused by frequency selective fading. OFDM can also effectively support ΜΙΜΟ and SDMA, and SDMA can be applied independently to each subcarrier and can therefore provide good performance in the frequency selective channel. For clarity, the following description uses OFDM to transmit data. It may be necessary to support OFDM while maintaining backward compatibility with HRPD revisions 0, A, and B. In HRPD, the pilot and MAC segments can be demodulated by all active terminals at any time, and the traffic segments can only be demodulated by the servoed terminal. Therefore, backtracking compatibility can be achieved by maintaining the pilot and MAC segments and modifying the traffic segments. The OFDM data may be transmitted in an HRPD waveform by replacing the CDM data in a given 400 chip traffic segment with one or more OFDM symbols having a total duration of 400 chips or less. 3A shows a single carrier slot structure 300 that supports OFDM in HRPD. 1 l8974.doc 11 For the sake of simplicity, only one half slot is shown in Figure 3A. The half slot includes: (i) a consumable segment including a 96-chip pilot segment at the center of the half slot and two 64-chip MAC regions on either side of the pilot segment And (ii) two traffic segments on either side of the consumable segment. In general, each traffic segment can carry one or more OFDM symbols. In the example shown in Figure 3A, each traffic segment carries two OFDM symbols, and each OFDM symbol has a duration of 200 chips and is transmitted in an OFDM symbol period of 200 chips. Figure 3B shows a single carrier slot structure 302 that supports CDM and OFDM in HRPD. The half slot includes: (1) a consumption segment including a 96-chip pilot segment and two 64-chip MAC segments, and (ii) two traffic segments in the consumption zone On both sides of the segment. In one design, CDM or OFDM can be selected for each traffic segment. In this design, each CDC data can be carried by each of the traffic segments when CDM is selected, or one or more OFDM symbols can be carried by each of the traffic segments when OFDM is selected. In other designs, a traffic segment can carry CDM data and OFDM data. For example, a traffic segment can carry CDM data in one half of the traffic segment and carry one or more OFDM symbols in the other half of the traffic segment. In general, OFDM symbols can be generated based on various OFDM symbol numerologies or designs. Each OFDM symbol is digitally associated with a particular value of a related parameter, such as OFDM symbol duration, number of subcarriers, loop preamble length, and the like. The OFDM symbol duration should be an integer divisor of the 400 chip traffic segment in order to fully utilize the traffic segment. In addition, the sample rate of the OFDM symbol should be an integer multiple of the chip rate of the CDM data 118974.doc 12 1336188 to simplify the handling at the access point and the terminal. Three example OFDM symbolic digits for HRPD are listed. These digital studies are selected to be compatible with the HRPD slot structure and chip rate such that (1) an integer number of OFDM symbols are transmitted in a traffic segment and (ii) the sample rate of the OFDM symbol is the chip rate of the CDM data. Integer multiple. The digits are further selected such that the total number of subcarriers (which determines the discrete Fourier transform (DFT) size) allows efficient generation of OFDM symbols. For these digits, the total number of subcarriers is not a power of two but a small prime factor. For example, 90 subcarriers can be obtained with a quality factor of 2, 3, 3, and 5. A small prime factor may allow for efficient mixed base fast Fourier transform (FFT) implementation to produce OFDM symbols. The numerology shown in Table 1 allows for the efficient embedding of OFDM data in the HRPD forward link waveform.

These OFDM symbolic digits provide information on Doppler extensions. (D〇ppler spread) and different tolerances for multipath delay tolerance. Digital 1 has the largest subcarrier spacing and the shortest cyclic preamble compared to digital 2 and 3. Therefore, Digital 1 can provide better Duller tolerance (attributable to Subcarrier spacing) and lower delay tolerance (due to shorter cyclical terms) is the high spectral efficiency in the submarine-enabled south speed vehicle channel. Digital Studies 3 and Digital Studies 1 and 2 Compared to having the smallest subcarrier spacing and the longest cyclic preamble. Therefore, Digital 3 can provide lower Doppler tolerance (due to smaller subcarrier spacing) but higher delay tolerance ( Due to the longer cyclic preamble), it can enable high spectral efficiency in the presence of large multipath delays (such as multipath delays induced by repeaters). Other OFDM symbolic digits can also be used. In the traffic segment. In general, OFDM symbolic digitization can be selected such that: (i) 〇 FDM symbol duration and sample rate are compatible with HRPD slot format and chip rate, respectively, and (ii) DFT size allows for validity 0FDM symbol generation.

Different digital studies can be used for different terminals. A suitable digital science can be selected for the terminal based on the channel conditions of each terminal. For example, Digital 1 can be used for high speed traveling terminals, Digital 3 can be used for terminals with large multipath delay spread, and Digital 2 can be used for terminals with medium speed and/or medium multipath delay spread. machine. 4 shows a multi-carrier slot structure 400 that supports cdm in HRPD. In HRPD Revision b, multiple 1 xhrpd waveforms can be multiplexed in the frequency domain to obtain a multi-carrier HRPD waveform that fills a given spectrum configuration. In the example shown in Figure 4, the three 1 x HRPD waveforms for the three HRPD carriers 1, 2, and 3 are frequency multiplexed in a 5 MHz spectrum configuration. Each lxHRPD waveform is generated for a different carrier and occupies approximately 125 MHz. The three lxHRPD waveforms occupy approximately 3x1.25 = 3.75 MHz, which leaves a relatively large guard band at the two edges of the 5 MHz spectrum configuration. The spacing between adjacent carriers is not specified in the HRPD but is typically chosen to provide a small transition band between adjacent lxHRPD waveforms. As shown in Figure 4, the multi-carrier HRPD waveform contains three consumption segments and six traffic segments for three of the carriers in each half slot. As shown in Figure 4, each traffic segment can carry CDM data. The CDM data in each of the multi-carrier HRPD waveforms can be selectively replaced by OFDM data. In addition, the traffic and consumption segments in the multi-carrier HRPD waveform can be arranged to efficiently utilize the spectrum configuration. Figure 5 shows a multi-carrier slot structure supporting CDM and OFDM in HRPD. 118974.doc •15· 1336188 5 00. In the example shown in Figure 5, three HRPD carriers are transmitted in a 5 MHz spectrum configuration and the equal-equivalent carriers are spaced as closely as possible to improve bandwidth utilization. For each HRPD carrier, each half slot includes: (1) a consumable segment including a pilot segment and a MAC segment; and (ii) two traffic segments on both sides of the consumable segment . The HRPD carrier 1 is included in the traffic segments (TS) la and lb on the left and right sides of the consumption segment, and the HRPD carrier 2 is included in the traffic segments 2a and 2b on the left and right sides of the consumption segment, and the HRPD carrier 3 includes The traffic sections 3a and 3b on the left and right sides of the consumption section. Each of the traffic segments for each HRPD carrier can carry CDM data or OFDM data. For a 3-carrier HRPD in a 5 MHz spectrum configuration, as shown in Figure 5, an OFDM symbol can be generated at a sample rate of 4x1.2288 = 4.9152 Mcps 〇 = 4). The OFDM symbol can then occupy most of the 5 MHz spectrum configuration. Alternatively, an OFDM symbol can be generated at a sample rate of 3 X 1.2288 = 3.6864 Mcps («=3), which is not shown in FIG. An OFDM symbol can be generated for each OFDM symbol period in a traffic time interval. Each OFDM symbol period is 200 chips in the case of OFDM symbol number 2 in Table 1. The OFDM symbols may carry OFDM data in (i) subcarriers corresponding to the traffic segments for OFDM and (ii) remaining available subcarriers at both edges of the spectral configuration. The OFDM symbol can also be made to have a null value on the subcarrier corresponding to the traffic segment having the CDM data. The OFDM symbols can thus carry OFDM data that can selectively replace CDM data for zero or more traffic segments of zero or more HRPD carriers. OFDM allows for better utilization of the available spectrum in a 5 MHz spectrum configuration. H8974.doc -16- 1336188 may select the spacing between HRPD carriers based on various factors such as the pulse shaping filter for CDM, the manner in which CDM data is generated, and/or the OFDM data. The guard subcarriers can be used at both edges of the spectrum configuration, and the guard subcarriers are subcarriers that do not have transmission. The number of guard subcarriers at the edge of the strip can be selected based on spurious emission requirements and/or other factors. 6 shows a multi-carrier slot structure 600 that supports CDM and OFDM in HRPD and more fully utilizes available bandwidth. The trough structure 600 includes all of the traffic segments and consumable segments in the trough structure 500 of FIG. The slot structure 600 further includes OFDM data in a portion of the spectrum of the pilot or MAC segments that are not used in the elapsed time interval of 224 chips. Additional OFDM symbolic digits may be defined for the elapsed time interval covering the 224 chips of the pilot and MAC segments. Such numerology may be selected such that (i) an integer number of OFDM symbols can be transmitted in the elapsed time interval and (ii) the sample rate of the OFDM symbol is an integer multiple of the chip rate. Two examples of OFDM symbolic digitization for the time interval are listed. The OFDM symbol transmitted in the elapsed time interval is referred to as the "long" OFDM symbol because its duration is "normal" sent in the traffic interval than in the case of the corresponding digital science in Table 1. The duration of the OFDM symbol is long.

As described below, each OFDM symbol period can be used in the elapsed time interval. Generating an OFDM symbol. The OFDM symbol can carry OFDM data in subcarriers corresponding to a portion of the bandwidth that is not used for the pilot segment and the MAC segment. The OFDM symbol can be corresponding to the pilot segment and the MAC segment. The subcarrier has a null value. One or more long OFDM symbols are used in the elapsed time interval to improve overall spectrum utilization.In the designs shown in Figures 5 and 6, four logical channels Chi, Ch2, Ch3, and Ch4 can be defined for the traffic segment. These logical channels may also be referred to as data channels, traffic channels, etc. The logical channel Chi may include the traffic segments 1a and 1b transmitted on the HRPD carrier 1, and the logical channel Ch2 may include the information transmitted on the HRPD carrier 2. For the traffic segments 2a and 2b, the logical channel Ch3 may include the traffic segments 3a and 3b transmitted on the HRPD carrier 3, and the logical channel Ch4 may include the traffic segments 4a, 4b and 4c transmitted on the remaining available spectrum. The logical channels Chi, Ch2, and Ch3 thus correspond to subcarriers that overlap with the HRPD carriers 1, 2, and 3. The logical channels Chi, Ch2, and Ch3 can be switched between CDM and OFDM in each slot, each half slot, and the like.

These logical channels can be scheduled independently. For example, each logical channel can be scheduled based on channel quality feedback received from the terminal used for the logical channel. In general, any number of HRPD carriers can be transmitted in a given spectrum configuration. For each HRPD carrier, each traffic segment can carry CDM data or OFDM data. The OFDM data may also be transmitted in the remaining available spectrum that is not used by the HRPD carrier. Figure 7 shows a slot structure 700 that supports OFDM and CDM for a single HRPD carrier in a 5 MHz spectrum configuration. In the example shown in Figure 7, a single HRPD carrier is located near one edge of the 5 MHz spectrum configuration. As described above in Figures 2 through 6, the pilot and MAC segments for the HRPD carrier are generated and transmitted at the center of the half-slot. Each traffic segment of the HRPD carrier can carry CDM data or OFDM data. An OFDM spectrum can be defined to include all of the available spectrum in the spectrum configuration (except for HRPD carriers). In the example shown in Figure 7, the OFDM spectrum contains the available spectrum on both sides of the HRPD carrier. Normal OFDM symbols and long OFDM symbols can be extended and used to carry data in the OFDM spectrum. The traffic data, signal transmissions, and pilots can be transmitted in the OFDM spectrum in any manner (e.g., using any of the techniques typically used in systems employing only OFDM or OFDMA). For example, pilot and signal transmissions can be transmitted in any manner over any subcarrier and symbol period. The available subcarriers and symbol periods can also be configured for any number of terminals, and any data can be sent to the scheduled terminal at 118974.doc 19 1336188. In the design shown in FIG. 7, two logical channels Ch 1 and Ch2 ° logical channel Chi are defined to include the traffic segments 1a and 1b transmitted on the HRPD carrier 1, and the logical channel ch2 is included in the OFDM spectrum. Traffic sections 2a to 2f. The logical channel chi can be switched between CDM and OFDM in each slot, every half slot, and the like. The logical channel Ch2 is not limited to any HRPD carrier and can operate in pure OFDM mode to carry only OFDM data. The traffic data, signal transmission, and/or pilot can be transmitted in OFDM in any manner on logical channel Ch2. Figure 8 shows an HRPD slot structure 800 supporting OFDM in a 5 MHz spectrum configuration. In the example shown in Figure 8, the spectrum configuration does not contain HRPD carriers. Normal OFDM symbols and long OFDM symbols can be used to transmit data throughout the available spectrum (except for the protection subband at the edge of the band). The logical channel Ch 1 can be defined to cover the entire available spectrum. The logical channel Chl can be operated (as if it were for an OFDM/OFDMA system) and it can have design elements from other OFDM/OFDMA technologies such as Flash OFDM®, IEEE 802.20, LTE, and the like. The time-frequency resources in the logical channel Chi can be divided into traffic resources for traffic data, signal transmission resources for signal transmission, pilot resources for pilots, and the like. Signal transmission data can be used to schedule terminals and assign traffic resources to scheduled terminals. Signal transmission data can also be used to facilitate hybrid automatic retransmission (H-ARQ) feedback, power control, and the like. Various structural elements and physical layer features of flash OFDM®, IEEE 802.20 'LTE and/or other OFDM/OFDMA systems can be used for the logical channel Chi. 118974.doc • 20- 1336188 FIG. 9 shows a block diagram of one of the access points 110 and the terminal 120, the access point and the terminal being one of the access points and terminals in FIG. For the sake of simplicity, only the processing unit for transmission on the forward link is shown in FIG. At access point 110, TX CDM/OFDM processor 920 receives and processes the traffic data and signal transmissions and provides output samples as described below. Transmitter (TMTR) 922 processes (e.g., converts to analog, amplifies, filters, and upconverts) the output samples and produces a forward link signal transmitted via antenna 924. At terminal 120, antenna 952 receives the forward link signal from access point 110 and provides the received signal to receiver (RCVR) 954. Receiver 954 processes (e. g., filters, amplifies, downconverts, and digitizes) the received signals and provides received samples. The RX CDM/OFDM processor 960 processes the received samples in a manner complementary to the processing by the TX CDM/OFDM 920, as described below, and provides the decoded data to the terminal 120 and the received signal transmission. Controllers 930 and 970 direct operations at access point 110 and terminal 120, respectively. The memory 932 and 972 store the program code and data for the access point 110 and the terminal device 120, respectively. Figure 10 shows a block diagram of a TX CDM/OFDM processor 920a, which is designed for one of the TX CDM/OFDM processors 920 of Figure 1. Processor 920a includes (1) a CDM processor 1010 that generates CDM waveforms that carry CDM data and consumes data, and (ii) an OFDM processor 1050 that generates OFDM waveforms that carry OFDM data. Within the CDM processor 1010, the encoder/interleaver 1012 receives the traffic data to be transmitted using the 118974.doc -21 - 1336188 CDM to encode the traffic data based on the _ encoding mechanism, and interleaves (or reorders) the encoded Information. The mapper mapper maps the interleaved data to the data symbols based on a modulation mechanism. The demultiplexer (Demux) 1〇16 demultiplexes the data symbols into multiple (for example, 16) streams. The Walsh cover unit 1 覆盖 18 covers or channels each data symbol stream with different "chip Walsh codes to obtain a corresponding data chip stream. The summer 1020 pair is used for multiple wales. Multiple (eg, 16) data chip streams are summed and the CDM data is provided at the chip rate. The τχ processor 1G22 receives the signal transmission with the mMAC segment and the pilot for the pilot segment. The data is generated at the chip rate for the consumption segment. The TDM multiplexer (Mux) 1024 receives the CDM data from the summer device and the consumption data from the processor 〇22, and carries the CDM. The CDM data is provided in the traffic section of the data, and the consumption data is provided in the consumption section. The multiplier 1026 multiplies the output of the multiplexer 1024 by the pseudo-noise (pN) sequence for the access point and encodes the code. The slice rate provides an output chip. The pulse shaping filter 1028 filters the output chips and provides a cdm waveform for an HRpD carrier. Multiple execution individuals of the CDM processor can generate multiple HRpD carriers for multiple CDM waveforms. These multiple CDM waveforms can be upconverted to the digital or analog domain to Appropriate frequency. Within the OFDM processor 1050, the encoder/interleaver 1 〇 52 receives the traffic information to be transmitted using OFDM to alpha, encodes the traffic data, and interleaves the encoded data. The symbol mapper 1〇54 maps the interleaved alternatives to the data symbols. The symbol-to-subcarrier mapper 1〇56 maps the data symbols to the subcarriers for OFDM. The zero insertion unit 1〇58 is not used for 118974. Doc -22- OFDM subcarriers (eg, subcarriers, null subcarriers, and guard subcarriers corresponding to the CDM traffic section and the consumption section) are inserted with a zero symbol (which has a signal value of zero). Discrete Fourier An inverse transform (IDFT) unit 1060 performs a K-point IDFT on the data symbols and zero symbols for the K total subcarriers in each OFDM symbol period and provides a useful portion containing K time domain samples. K depends on the OFDM symbol Digitally and given for normal OFDM symbols and long OFDM symbols in Tables 1 and 2. The Cyclic Preamble Insertion Unit 1062 copies the last C samples of the useful portion and appends these C samples to the front of the useful portion so that Form one at sample rate There are K+C samples of OFDM symbols. The sample rate can be n times the chip rate, where η can be equal to 1, 2, 3, 4, etc. The repeated part is called the cyclic preamble and is used against the frequency selection. The ISI caused by the fading. The windowing/pulse shaping filter 1064 windowizes and filters the samples from unit 1062 and provides an OFDM waveform. The summer 1 〇7 〇 pairs the CDM waveforms from the CDM processor 1010 and from the OFDM processor The OFDM waveforms of 1050 are summed and provide an output waveform.Figure 11 shows a block diagram of a TX CDM/OFDM processor 920b, which is another design of the TX CDM/OFDM processor 920 of Figure 1. Processor 920b maps the CDM data to subcarriers for CDM and maps the OFDM data to subcarriers for OFDM. Processor 920b then generates an output waveform based on the mapped CDM data and OFDM data. Within processor 920b, TX CDM processor 1110 receives the traffic data, signal transmissions, and pilots to be transmitted using the CDM and provides output chips. Processor 1110 can include units 1012 through 1026 in FIG. The DFT unit m2 performs an L-point 118974.doc • 23 - 1336188 DFT for the output chips in each OFDM symbol period and provides L frequency-domain symbols for the L sub-carriers. L is the number of subcarriers corresponding to an HRPD carrier and may depend on the number of 〇fdm symbols. The encoder/interleaver 1120 and the symbol mapper 1122 process the traffic data to be transmitted using the FDM and provide the data symbols. The symbol-to-subcarrier mapper 1130 maps the frequency domain symbols from the DFT unit 1 Π 2 to the 钊 carrier for cdm and further maps the data symbols from the symbol mapper 丨丨 22 to the subcarriers for OFDM. Zero insertion unit 1132 inserts a zero symbol on subcarriers (e.g., null and guard subcarriers) that are not used for CDM or OFDM. The IDFT unit 1134 performs a K-point 1DFT on the K symbols for each 0Fdm symbol period and provides a useful portion containing K time-domain samples. The loop preamble insertion unit 丨 136 inserts a loop preamble into the useful portion and provides a 〇 FDM symbol containing K + c samples at the sample rate. Windowing/pulse shaping filter 1138 windowizes and filters samples from unit 1136 and provides an output waveform. Filter 1138 can provide steeper spectral attenuation than filter 1 〇 64 in Figure 1 , which allows for better utilization of the spectrum configuration.

These techniques can also be used in other combinations of Xigong mechanisms, such as sc_FDM, CDM and TDM, and 〇FDM, TDM, and 〇FDM. These techniques can also be used with other wireless communication systems and for forward and reverse links. In wireless systems, ensuring reliable data packet delivery on each individual transmission can be inefficient. Inefficiency is especially evident in systems where the basic channel conditions are transmitted from one transmission to another. For example, in an OFDM system, there may be a wide variation in the received signal-to-noise ratio (SNR) between frames/packets, making it difficult to guarantee a small frame error rate (FER) for each packet transmission. And inefficient. This difficulty and inefficiency also applies to other communication systems employing orthogonal multiple access techniques including, but not limited to, TDMA, FDMA, and CDM. In such communication systems, a packet retransmission mechanism such as an Automatic Retransmission/Repetition Request (ARQ) procedure can be used to help reduce such inefficiencies. However, ARQ procedures may cause higher packet latency because each packet may take an average of longer to pass β. In general, large packet latency may not be a significant problem for data traffic, but It may be detrimental to voice traffic or other types of applications that require low latency in information transmission. In addition, it is expected that the packet transmission latency will increase as the number of users in the system continues to grow. Therefore, to improve system capacity (e.g., based on system throughput or the number of users using the system at the same time, etc.), the transmission latency should be kept low or small. The ARQ typically includes an acknowledgment/negative acknowledgment (ACK/NACK) signal to indicate whether the terminal has successfully received the 118974.doc -27- 1336188 - packet. As a non-limiting example, the terminal machine checks: the check algorithm (such as the hash function two:: the seal... such a hash function is successfully evaluated by the loop c, and (iv) all the bit systems can issue one If the ACKe indicating that the terminal does not need to retransmit the packet is CRC = evaded, it may not be *+ in the packet; all the bits in the 均 are correct and the terminal sends out a different terminal and needs to retransmit the packet. The NACKe uses the packet transmission on the forward keyway, which knows the full slot to the link towel. The half-slot transmission results in a larger granularity of L and (result) a greater chance of successfully transmitting smaller packets. Although the latency may be the same, the smaller granularity means a smaller data size per sub-paeket and a greater chance of transmitting each sub-packet without any transmission of any given sub-packets. The half slot may transmit a packet or sub-packet (ie, a portion of the 'package) depending on the packet size and the half-slot payload size. As used herein, "package" generally refers to the payload or half-slot of the slot. Payload. - familiar with this The skilled artisan will recognize that a packet defined by a slot such as ifcb may include a subpackage of a data packet or a packet of a conventional data packet.

In Figure 14A, each packet (or sub-packet) occupies one slot and the transmission channel is configured with four interlaces to indicate that there may be a specified or different terminal in the interlace The data packet is wrapped in four different streams.

Therefore, the earliest opportunity for an access point to receive a re-sent packet is the four packets after the original packet is sent.

As a result, the ARQ for the full slot packet will appear at ARQ3 time and there will be no ARQ4. Alternatively, any given four-slot section may include four staggered or half-sloted interlaces of the full slot. In other words, as a non-limiting example, four of the full slots may have eight staggered half-slots. The eight-interlace of the half-groove may have four interlaces of the full slot. Figure 15 illustrates various modulation orders associated with the payload size and the number of retryes that may be used in embodiments of the present invention. Whenever an access point has to resend a packet, the access point can change the modulation to have a better chance of successfully transmitting the packet. In addition, the terminal can measure the quality of the forward link channel and transmit the information to the access point. The access point causes ^ to use the received channel conditions to predict the transmission format of the cipherable text and the rate at which the packet is transmitted. As an unrestricted 118974.doc •30· U36188 The example terminal can use the Channel Quality Feedback Channel (CQICH) to deliver the best channel quality measurement to the base station. The channel quality can be measured in terms of carrier interference (C/Ι) ratio based on the received forward link signal. The C/I value can be mapped to the Channel Quality Indicator (CQI) symbol. In addition, the terminal can provide data rate control (DRC) information to access resources based on, for example, CM measurements from previous forward link transmissions. The access point can use the DRC information to determine what type of modulation is used for the packet after receiving the DRC information. The spectral efficiency is determined by a modulation mechanism. Various modulation mechanisms are available for data transfer. Each modulation mechanism is associated with a signal distribution (signal constellati) that contains a 'signal point', among which. Each signal point is identified by a composite value boundary for each signal point and by a B-bit binary value, wherein for the symbol mapping, the code bits 待 to be transmitted are first grouped into B code bits. Each group of the group of β B code bits forms a B-bit binary value mapped to a particular signal point, and then transmits the signal point as a modulation symbol of the same group of code bits. Each modulation symbol thus carries information for B code bits. Some non-limiting example modulation processes that can be used in embodiments of the present invention are quadrature phase shift keying mechanism (Qpsk), 8-phase shift keying mechanism (8_PSK), and 16 quadrature amplitude modulation (i6 qam) and 64. QAM. Therefore, as an example from Fig. 15, for the payload size of 4096 bits when the packet is transmitted for the first time, the packet can be modulated by the modulation order 6 (i.e., QAM). If the packet needs to be resent, the packet can be sent again with a modulation order of 6 (i.e., 64 QAM) when the packet is sent for the second time. However, if 1I8974.doc 31 is required to resend the packet for the first time (that is, the third modification is the modulation order 4 (ie, :transmission)' then the access point will be modulated to recognize that Small effective negative cropping) ° is generally familiar to the person skilled in the art and is still within the range of half-slot packet size. 'You can use a smaller modulation order. The achievable combined rate of the various loads A and the number of retests. The protocol rate on Figure J 6 corresponds to the payload size, number of transmissions, and modulation order from Figure 15. =17 shows - the block diagram of the access point and a terminal. In addition to the operation blocks used for the transmission and reception of the reverse link, this block diagram is shown in Figure 1. The functional description of the forward link described above with respect to Figure 9 is equally applicable to the diagram. 17. For the reverse link, in the terminal, the controller 97() uses the data from the U CDM/OFDM processor 96() and determines if the packet from the half slot has been successfully received as explained earlier. The controller 970 & χ data processor 980 then combines the ARQ and sends it to the transmitter (TMTR) 982 for transmission to the access point via antenna 952. On the access point side, the receiver (RCVR) 942 receives the reverse link information via the antenna 924. The RX data processor 940 and controller 930 decode the ARQ to retrieve information such as ACK/NACK information, such as CQI forward link quality information, and data rate control information such as drc. Using a combination of DRC, CQI, and ACK/NACK information, the controller can decide whether a packet for the next channel should be sent with a different modulation mechanism. Figure 18 shows a process for transmitting and receiving a half slot packet. The process element on the left side is the access point 118974.doc -32- 1336188 process (10)' which is executed by the access point and the process element on the right side is the terminal machine process mo which can be executed by the terminal. The illustrated process is for transmitting and (possibly) retransmitting a given packet for a given data stream. As would be appreciated by those skilled in the art, it will be recognized that there are many Packets and the sending and monitoring of multiple streams involve many other processes.

Alternatively, the access point can begin processing a packet without DRC information. This is especially true for subsequent packets in a data stream. From the start-to-start point, process 1752 determines the data rate and modulation mechanism for the packet. This determination can be affected by the DRC information (if it exists) and the payload size. Process 1754 then sends the packet in the half slot to the terminal. Of course, other processes can be occurring to fill other traffic segments or half slots in any given slot to compensate for transmission.

Process 1706 determines packet integrity, which may include performing a CRC to determine if the data was successfully received, analyzing channel quality to derive a CQI, or a combination thereof. Decision block 1708 indicates that retransmission may be required if a bit error is received. If retransmission is required, then process 1710 defines that a NACK should be sent. If no retransmission is required, then process 1712 defines that an ACKe procedure 1714 should be sent to indicate the transmission of an ARQ containing at least ACK/NACK information. ARQ can also contain other information such as CQI information and DRC information. Decision block 1756 indicates whether the access point determines whether to receive the ACK or is part of the ARQ. If an ACK is received, the process exists because 118974.doc • 33· 1336188 is not required to resend the current packet. For subsequent packets in the data stream, the process will repeat as it enters the access point process 1750 or the beginning of the terminal process 1700. If a NACK is received, the process loops to 1752 to determine the data rate for the packet. The data rate on the reverse loop determines the effect of the combination of the number of retries (not shown in Figure 18), payload size, DRC information (if it exists), and CQI information (if it exists).
