Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present disclosure relates generally to communications, and more particularly to techniques for high rate data transmission. [Prior Art] Wireless communication systems are widely deployed to provide various communication services such as voice, packet data, broadcast, and messaging. Such systems may be multi-directional proximity systems capable of supporting multiple users to communicate by sharing available system resources. Examples of such multi-directional proximity systems include code division multiplex access (CDMA) systems, timed multidirectional proximity (TDMA) systems, time division multiplex access (FDMA) systems, and orthogonal time division multiplex access ( OFDMA) system. The data usage of wireless communication systems continues to grow due to the increased number of users and the emergence of new applications with higher data requirements. However, given systems typically have limited transmission capacity, which is determined by system design. A substantial increase in transmission capacity is often achieved by deploying a new generation or new design system. For example, the second generation (2G) to the third generation (3G) in the honeycomb system provides substantial improvements in data rates and characteristics. However, new system deployments are capital intensive and often complex. Therefore, there is a need in the art for techniques to improve the transmission capacity of wireless communication systems in an efficient and cost effective manner. SUMMARY OF THE INVENTION Techniques for utilizing multiple carriers on a forward and/or reverse link to significantly improve transmission capacity are described herein. These techniques are applicable to various wireless communication systems such as the Cdma2000 system. These techniques provide various benefits to the relatively small changes to the existing channel structure designed for single carrier operation 14319I.doc 201004259. In accordance with an embodiment of the invention, a device is described that includes at least one processor and a memory.

The (the) processor then receives the data transmission on one or more of the plurality of FL carriers. In accordance with another embodiment, a method is provided in which a plurality of WTRUs and an assignment of at least one RL carrier are received. Thereafter, data transmission is received on one or more of a plurality of carriers. C ' according to yet another embodiment, an apparatus is described, the apparatus comprising: means for receiving a plurality of FL carriers and at least one ft [an assignment of a carrier; and for receiving on one or more of a plurality of FL carriers The component of data transmission. According to yet another embodiment, a device is described that includes at least one processor and a memory. The processor obtains an acknowledgment of packets received on a plurality of data channels (e.g., F-PDCH), and uses an orthogonal code assigned to each data channel to channel the acknowledgment of the data channel to generate the data. A channel sequence of one of the channels, and a modulation symbol based on a plurality of data channels produces a modulation channel (eg, 'R-ACKCH). According to yet another embodiment, a method is provided in which an acknowledgment of packets received on a plurality of data channels is obtained. The confirmation of the data channel is channelized using the orthogonal code assigned to each data channel to generate a sequence of symbols for the data channel. A modulation symbol of a confirmed channel is generated based on a sequence of symbols of a plurality of data channels. According to yet another embodiment, an apparatus is described, the apparatus comprising: means for obtaining a confirmation of a packet received on a plurality of data channels; for using an orthogonal code assigned to each data channel using 143191.doc 201004259 Channelizing the confirmation of the data channel to generate a component of the sequence of the poor channel; and means for generating a modulation symbol for the confirmation channel based on the sequence of symbols of the plurality of data channels. According to yet another embodiment, a device is described that includes at least one processor and a memory. The (the) processor obtains a full channel quality indication (CQI) report for a plurality of FL carriers, each full CQI report indicating the received signal quality of an FL carrier. The (these) processors transmit a full CQI report of a plurality of fl carriers in a simultaneous interval on a CQI channel (e.g., R-CQICH). According to yet another embodiment, a method is provided in which a full CQI report for a plurality of FL carriers is obtained. Each CQI report indicates the received signal quality of an FL carrier. These full CQI reports for multiple FL carriers are transmitted in different time intervals on a CQI channel. According to yet another embodiment, an apparatus is described, the apparatus comprising: means for obtaining a full CQI report for a plurality of FL carriers, each full cq report indicating a received signal quality of an FL carrier; The means for transmitting the complete CQI reports of the plurality of FL carriers in different time intervals on the channel. According to yet another embodiment, a device is described that includes at least one processor and a memory. The (these) processors operate in a control hold mode that allows transmission of the gate pilots, and when in the control hold mode, receive a data channel (e.g., p_pDCH) that is transmitted on the link, if no other The t-transmission is transmitted on a reverse link, and a gating pilot is transmitted on the reverse link, and if a transmission is being transmitted on the reverse link, H3191.doc -6 - 201004259 transmits one on the reverse link. Full pilot. According to yet another embodiment, a method is provided wherein the terminal device operates in a control mode mode that allows transmission of the gate pilot. #In the control hold mode, the channels transmitted on the forward link are decremented. If there is no other transmission on the reverse link, a idle pilot is transmitted on the reverse link.

Various aspects and embodiments of the invention are described in further detail below. [Embodiment] The term "exemplary" is used herein to mean "serving as an instance, instance, or child." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous. Fig. 1 shows a wireless communication system L and a first 100 that do not have a plurality of base stations 110 and a plurality of terminal units 120. A base station is typically a fixed station that communicates with the terminal and may also be an access point, a Node B, a Base Transceiver Subsystem (BTS), and/or some other terminology. Each base station 110 provides a specific geographic area 102 with a coverage I. The term "cell" may refer to base station 143191.d, 201004259 and/or its coverage area depending on the terminology used. For this reason, the number of zones is 2, and a base station coverage and 104 domain can be used. 'For example, three smaller areas _, axis C terms "sectors" depending on the use of the term - 轫, 丨 ^ 】 Q疋h shape may refer to service, regional fixed stations and / or frost 荖 FA eat and ' /, 盍 盍 域 domain. For small partitions. °, 3, the base station usually serves all sectors of the community. The transfer technique described herein can be used in systems with small divisions, r-knife, and systems with unknocked cells. For the sake of simplicity, the term "fixed table" is used in the following description. □ 疋 以及 and the terminal 120 serving a cell are usually distributed over the entire system, and the parent terminal can be a mobile terminal. A terminal can also be called a mobile station, user equipment, or some other terminology. The terminal can be a cellular phone, a personal digital assistant (PDA), a wireless device, a handheld device, a wireless data device, and the like. The terminal can communicate with zero, one or more base stations on the forward and/or reverse link at any given time. The forward link (or downlink) refers to the communication link from the base station to the terminal and the reverse link (or uplink) refers to the communication link from the terminal to the base station. The system controller 130 interfaces to the base station 11 and provides coordination and control for such base stations. System controller 130 can be a collection of single network entities or network entities. , a The routing technology described herein can be used in various wireless communication systems such as Cdma, TDMA, FDMA, and OFDMA systems. The cdma system can implement one or more radio technologies, such as cdma2, wideband CDMA (W-CDMA), and the like. Edma2_ covers IS_2_, is_85/, 143191.doc 201004259 IS-95 and other standards. A TDMA system can implement a radio technology such as the Global System for Mobile Communications (GSM). These various radio technologies and standards are well known in the art. W-CDMA and GSM are described in a document from an association called "3rd Generation Partnership Project" (3GPP). Cdma2000 is described in the literature from an association named "3rd Generation Partnership Project 2" (3GPP2). The 3GPP and 3GPP2 documents are publicly available. For clarity, the following describes the transmission techniques specifically for the cdma2000 system, which may be "CDMA lx-EVDV", "CDMA lx", "CDMA lx-EVDO" and / or "1 x" systems. Cdma2000 defines various data and control channels that support data transmission on the forward and reverse links. Table 1 lists some of the data and control channels for these forward and reverse links and provides a short description for each channel. In the description of this document, the prefix "F-" indicates the channel of the forward link, and the prefix "R-" indicates the channel of the reverse link. These channels are described in detail in "TIA/EIA IS-2000.2 Physical Layer Standard for cdma2000 Spread Spectrum Systems, Release D" (hereinafter TIA/EIA IS-2000.2) and "TIA/EIA IS-2000.3 Medium Access Control (MAC) Standard for cdma2000 Spread Spectrum Systems, Release D (hereafter TIA/EIA IS-2000.3), both from the Communications Industry Association, dated 2004 and available to the public. Cdma2000 version D is also known as IS-2000 version D, or simply ""Rev D". These data and control channels are also described in other standard documents of cdma2000. 143191.doc 201004259 Table 1 Link Channels --- Description Forward Keyway F-PDCH Forward Packet Data Channel - Used to send packet data to the F-PDCCH forward packet data in time-multiplexed (TDM) mode Control Channel - Control Data for Carrying Related F-PDCH F-ACKCH Forward Acknowledgment Channel - Carrying Feedback for Transmission Received on R-PDCH F-GCH Forward Allowed Channel - Used by the base station to allow the terminal to be in the R- Reverse link R-PDCH on the PDCH Reverse packet data channel - used to send packet data to the base station R-ACKCH Reverse acknowledgement channel - Transport feedback received on the F-PDCH Receiver R-CQICH R-PICH To the channel quality indicator channel - carry the forward link channel quality reversal pilot channel - carry the pilot on the reverse link R-REQCH reverse request channel - used by the terminal to request a higher data rate for the R_PDCH For example, F-PDCH, F-PDCCH, R-ACKCH, and R-CQICH are used for data transmission on the forward link. r_PDCH, R-REQCH, R-PICH, F-ACKCH, and F-GCH are used for data transmission on the reverse key path. In general, 'each channel can carry control information, data, pilots, other transmissions, or any combination thereof. Figure 2 shows an exemplary data transfer on the forward link in cdma2000. The base station has a data packet to be sent to the terminal. The base station processes each data packet to produce an encoded packet and further splits the encoded packet into multiple sub-packets. Each sub-package contains enough information to allow the terminal to decode and recover the packet in a good channel state. The base station transmits the first sub-packet A1 of packet A on f_pdcH in two time slots starting at time T!. The one-time slot in Cdma2000 has a duration of 1.25 milliseconds (ms). The base station also transmits a 2-time slot message indicating the transmission system on the F-143191.doc 201004259 PDCH to the terminal on the F-PDCCH. The terminal receives and resolves the code packet A1, determines that packet A is erroneously decoded' and sends a negative acknowledgment (NAK) on time R2. ACKCH. In this example, the ACK delay is 1 slot. The base station transmits the first sub-packet Β1 of the packet on the F-PDCH in four time slots starting at time τ3. The base station also transmits on the F-PDCCH a 4-time slot message indicating the transmission on the F-PDCH to the terminal. The terminal receives and decodes the sub-packet Β 1, determines that the packet is correctly decoded' and sends an acknowledgment (ACK) on the R-ACKCH at time Τ4. The base station transmits the second sub-packet Α2 of the packet on the F-PDCH at the beginning of the time interval Τ5. The terminal receives the sub-packet A2, decodes the sub-packets A1 and A2, determines that packet A is erroneously decoded, and transmits the NAK on the R-ACKCH at time T6. The terminal also periodically measures the channel quality of the base station that can potentially transmit data to the terminal. As described below, the terminal identifies the best base station and transmits a full and differential (Diff) channel quality indication (CQI) report on the R-CQICH. The CQI report is used to select the most suitable base station to send data to the terminal and to select the appropriate data rate for data transmission. In cdma2000, the base station uses a pseudo-random number (PN) sequence to spread the data at a rate of 1.2288 million chips per second (Mcps). The base station uses the spread spectrum data to modulate the carrier signal and produce a radio frequency (RF) modulated signal with a bandwidth of 1.2288 MHz. The base station then transmits the RF modulation signal at a particular center frequency on the forward link. Since a single carrier is modulated with data, this is called single carrier CDMA. The capacity of the forward link is determined by the number of data bits that can be reliably transmitted in the 1.2288 MHz RF modulated signal. On the reverse link, the terminal also uses the PN sequence to spread the data at a rate of 1,2288 Mcps and transmit the spread spectrum data at a special carrier frequency. The capacity of the reverse link is determined by the number of data bits that can be reliably transmitted on the data channel assigned to the terminal. In one aspect, multiple carriers are utilized on a link to achieve significant capacity improvements for the link. In one embodiment, a chip rate of 1.2288 Mcps is used for each of a plurality of carriers, the chip rate being the same as the chip rate for single carrier CDMA. This hardware, which is designed for single-carrier cdmA, also supports multi-carrier CDMA. 3 shows a diagram of an embodiment of a multi-carrier structure 3A. In this embodiment, there are K carriers available on the forward link and μ carriers are available on the reverse link where K>1 and Μ21. The forward link (FL) carrier is the carrier on the forward link and the reverse link (RL) carrier is the carrier on the reverse link. Carrier waves can also be referred to as RF channels, CDMA channels, and the like. κ FL carriers and RL RL carriers are arranged in G groups 'where G21. In general, any number of carrier groups can be formed and each group can include any number of FL carriers and any number of RL carriers. In the embodiment shown in Figure 3, each carrier group includes at least one fl carrier and an RL carrier ' such that G = M and Κ 2 Μ. As shown in FIG. 3, carrier group 1 includes FL carrier 1 to carrier 1, carrier group 2 includes FL carrier Ν! + 1 to Ν Ν + Ν 2 and RL carrier 2 ', etc., and carrier group μ includes FL carrier Κ - NM+1 to K and RL carrier M. In general, ]^1 to >^ may be the same or different. In one embodiment, for m = 1, ..., μ, Nm $ 4, and up to four FL carriers in each carrier group can be associated with a single rl carrier. The multi-carrier architecture 300 supports various system configurations. Configuration with multiple fl carriers and 143191.doc -12- 201004259 multiple RL carriers can be used for high rate data transmission on both forward and reverse links. Configurations with multiple FL carriers and a single RL carrier can be used for 'high rate data transmission on the forward link. A configuration with a single FL carrier and multiple RL carriers can be used for high rate data transmission on the reverse link. The appropriate configuration can be selected for the terminal based on various factors such as available system resources, data requirements, channel status, and the like. In an embodiment, the FL and RL carriers have different importance. For each group, one of the groups (eg, the first carrier is designated as a group of primary waves, and each remaining FL carrier in the group (if present) is designated as a group of auxiliary waves. K One (e.g., first) hole carrier in the FL carrier is designated as the primary FL carrier. Similarly, one of the rivers is used (e.g., the first known E-carrier is designated as the primary RL carrier. The terminal assigns any number of carriers, one of which is designated as the primary hole carrier of the terminal. It is also possible to assign any number of RL carriers to the terminal, such as XI and other RL carriers. ^ is the main carrier of the terminal downtime. Different sets of FL and RL carriers can be assigned to different terminals σ ° In addition, the 'p remaining time lapse can be based on various factors such as the factors noted above to a given terminal The machine assigns a different set of FL and RL carriers. In one embodiment, the terminal uses the primary FL and RL carriers for the following functions: • Issues on the primary RL carrier, • Call settings _ in the primary FL Receive signals on the carrier, • perform layer 3 signals on the primary FL carrier The delivery procedure, and • based on the primary FL carrier transmission selection-service base station. 143191.doc -13· 201004259 In an embodiment, the group FL primary wave in each carrier group controls the RL carrier in the group. The main wave can be used for the following functions: • Power control for transmitting R-PICH, • Rate control for transmitting R-PDCH, • Acknowledgement for transmitting reverse link transmission (on F-ACKCH), • Sending MAC control message (in F - PDCCH) to the terminal, and • Send forward grant message (on the F-GCH) to the terminal. The data and control channels in cdma2000 version D are designed for data transmission on a single carrier. Controlling some of the channels to support data transmission on multiple carriers. This modification may result in (1) the modified control channel being backward compatible with the control channel in cdma2000 version D and (2) easily capable of, for example, software and/or Or firmware to implement new changes, which can reduce the impact on the hardware design. The base station can transmit data to the terminal on the forward link on any number of any of the number of carrier groups. In the embodiment, each The RL carrier in a group carries R-ACKCH and R-CQICH for all FL carriers in the group. In this embodiment, the R-ACKCH carries the acknowledgement of the packets received by the F-PDCH for all FL carriers in the group. .

As shown in Figure 3, the terminal can monitor multiple FL carriers in a given group as it travels over a single RL carrier. The terminal can receive a plurality of packets on a plurality of F-PDCHs transmitted on the plurality of FL carriers. The terminal can acknowledge the multiple packets via a single R-ACKCH 143191.doc -14-201004259 transmitted on the single RL carrier. Depending on the number of FL carriers received, the R-ACKCH can be designed to carry the ability to acknowledge the acknowledgement of one or more packets. 4A shows a block diagram of an R-ACKCH structure 410 for use in cdma2000 version D. An R-ACKCH bit is generated in each 1.25 ms frame. The frame is a time slot. (1) If the packet is correctly decoded, the R-ACKCH bit may be ACK, (2) if the packet is erroneously decoded, the R-ACKCH bit may be NAK, or (3) if there is no pending For the packet, the R-ACKCH bit can be a null bit. The symbol repeating unit 412 repeats the R-ACKCH bit 24 times to generate 24 identical modulated symbols, further processing and transmitting the modulated symbols on the R-ACKCH. 4B shows an embodiment of a new R-ACKCH structure 420 that can support up to four R-ACKCHs of up to four FL carriers. The four R-ACKCHs can also be considered as four sub-channels of a single R-ACKCH and can be referred to as a reverse acknowledgement sub-channel (R-ACKSCH). In the following description, the acknowledgment channel for each FL·carrier is referred to as R-ACKCH instead of R-ACKSCH. Figure 4B shows a situation in which three R-ACKCHs are used for three FL carriers, which are referred to as CDMA channels 〇, 1 and 2. The R-ACKCH of each CDMA channel is implemented with a different set of signal point mapping unit 422, Walsh coverage unit 424, and repetition unit 426. Four chip Walsh codes w〇4, W/, and w24 are assigned to CDMA channels 0, 1, and 2, respectively. These Walsh codes are also referred to as Walsh functions or Walsh sequences and are defined in TIA/EIA IS-2000.2. A 143191.doc -15-201004259 R-ACKCH bit is generated for each CDMA channel in each 1.25 ms frame (or time slot). For CDMA channel 0, signal point mapping unit 422a maps the R-ACKCH bit of CDMA channel 0 to a value of +1, -1 or 0 depending on whether the R-ACKCH bit is an ACK, a ΝΑΚ or a null bit. . The Walsh overlay unit 424a overwrites the mapped value with a 4-chip Walsh code W〇4 assigned to CDMA channel 0. The Walsh coverage is achieved by (1) repeating the mapping values four times and (2) multiplying four identical values by four chips of Walsh code W〇4 to produce a sequence of four symbols. Repeat unit 426a repeats the 4-symbol sequence 6 times and generates a sequence of 24 symbols for CDMA channel 0. The processing of CDMA channels 1 and 2 is performed in a manner similar to CDMA channel 0. In each time slot, adder 428 adds the three 24-symbol sequences from repeating units 426a, 426b, and 426c of CDMA channels 0, 1, and 2, respectively, and provides 24 modulation symbols for the time slot. These modulation symbols are further processed and transmitted. The base station can recover the R-ACKCH bit of the CDMA channel by performing complementary decovering with a Walsh code assigned to each CDMA channel. 4C shows a block diagram of an embodiment of a new R-ACKCH structure 430 that can support up to eight R-ACKCHs, for example up to eight FL carriers. Figure 4C shows the case where 7 R-ACKCHs are used for 7 FL carriers, which are referred to as CDMA channels 0 through 6. The R-ACKCH of each CDMA channel is implemented using an individual set of one of the signal point mapping unit 432, the Walsh overlay unit 434, and the repetition unit 436. Eight chip Walsh codes W 〇 8 to W 68 are assigned to CDMA channels 0 through 6, respectively, which are defined in TIA/EIAIS-2000.2. For each CDMA channel, signal point mapping unit 432 maps the R-ACKCH bits of the CDMA channel to a value of + 1, -1 or 0. Walsh 143191.doc -16· 201004259 Coverage unit 434 overwrites the mapped value with an 8-chip Walsh code assigned to the CDMA channel and provides a sequence of 8 symbols. Repeating unit 436 repeats the 8-symbol sequence three times and produces a sequence of 24 symbols for the CDMA channel. In each time slot, adder 438 adds the seven 24-symbol sequences from repeating units 436a through 436g of CDMA channels 0 through 6, respectively, and provides 24 modulation symbols for the time slot. These modulation symbols are further processed and transmitted. 4B and 4C show exemplary r_AckCH structures 420 and 430 that do not support multiple R-ACKCHs and are backward compatible with the current R-ACKCH structure 410 shown in FIG. 4A. If only one CDMA channel is received, the R-ACKCH bit of the CDMA channel can be processed with Walsh code w04 or WQ8, and the R-ACKCH bits of all other CDMA channels can be set to null bits. The output of adder 428 or 438 will be the same as the output of repeating unit 41 2 in Figure 4A. These additional CDMA channels can be supported by transmitting R-ACKCH bits of additional CDMA channels using other Walsh codes. Depending on the length of the Walsh code, the repetition factor is reduced from 24 to 6 or 3. The R-ACKCH structure shown in Figures 4B and 4C allows the R-ACKCH bit to be recovered using the hardware designed for the R-ACKCH structure shown in Figure 4A. The hardware can generate 24 received symbols for the R-ACKCH in each time slot. The coverage of these 24 received symbols can be performed with Walsh codes in the software and/or firmware, which reduces the impact of upgrading the base station to support multi-carrier operation. A plurality of R-ACKCHs may be implemented with other structures, and are within the scope of the present invention. For example, multiple R-ACKCHs can be time-multiplexed and transmitted in different intervals of a given time slot. 143191.doc •17- 201004259

R-CQICH 在又一態樣中,描述一可支援多個FL載波之CQI回饋之 新R-CQICH結構。如圖3中所示,終端機可在於單個RL載 波上傳輸時監視一給定組中之多個FL載波。此等多個FL 載波可具有不同頻道狀態(例如,不同衰減特徵)且可在終 端機處達成不同接收信號品質。需要終端機為盡可能多的 已指派FL載波提供CQI回饋,以便系統可選擇適宜FL載波 來發送資料以及為每一選定FL載波選擇適宜速率。若系統 組態包括單個RL載波,則終端機可經由該單個RL載波在 單個R-CQICH上發送所有FL載波之CQI回饋。R-CQICH可 經設計具有載運一或多個FL載波之CQI回饋之能力。 在cdma2000版本D中,R-CQICH在每一 1.25 ms訊框(或 時槽)中可運作於兩個模式之一者(完全模式或差動模式) 中。在完全模式中,在R-CQICH上發送包括4位元值之完 全CQI報告。此4位元CQI值傳達一 CDMA頻道之接收信號 品質。在差動模式中,在R-CQICH上發送包括1位元值之 差動CQI報告。此1位元值傳達一 CDMA頻道之當前時槽與 先前時槽之間的接收信號品質差異。可如TIA/EIA IS-2000.2中所描述產生完全及差動CQI報告。 圖5八展示用於〇(1〇^2000版本0中之一11-0〇1(:11結構510 之方塊圖。視選擇完全還是差動模式而定,可在每一 1.25 ms訊框(或時槽)中為一 CDMA頻道產生4位元或1位元值。4 位元CQI值亦稱為CQI值符號。1位元CQI值亦稱為差動CQI 符號。塊編碼器512可用(12, 4)區塊碼對4位元CQI值進行 143191.doc -18 - 201004259 編碼以產生具有12個符號之碼字 冲 ^ a- rnu± ^ 、 付號重複單元514將1 以產生12個符號。切換器-為完全模 =塊編碼器512之輸出或為差動模式選擇重複單元514 之輸出。 可藉由使用指派給一特定基地台 + _ 之/天爾什碼覆蓋該報告 來發送CQI報告至該基地台。 兩什覆盍早元518為經選擇 以服務該終端機之基地台接收3 叹位凡沃爾什碼並產生相應2. R-CQICH In another aspect, a new R-CQICH structure that supports CQI feedback for multiple FL carriers is described. As shown in Figure 3, the terminal can monitor multiple FL carriers in a given group while transmitting on a single RL carrier. These multiple FL carriers can have different channel states (e.g., different attenuation characteristics) and can achieve different received signal qualities at the terminal. The terminal is required to provide CQI feedback for as many assigned FL carriers as possible so that the system can select the appropriate FL carrier to transmit the data and select the appropriate rate for each selected FL carrier. If the system configuration includes a single RL carrier, the terminal can transmit CQI feedback for all FL carriers on a single R-CQICH via the single RL carrier. The R-CQICH can be designed to have the ability to carry CQI feedback for one or more FL carriers. In cdma2000 version D, the R-CQICH can operate in one of two modes (full mode or differential mode) in every 1.25 ms frame (or time slot). In full mode, a full CQI report including a 4-bit value is sent on the R-CQICH. This 4-bit CQI value conveys the received signal quality of a CDMA channel. In the differential mode, a differential CQI report including a 1-bit value is transmitted on the R-CQICH. This 1-bit value conveys the difference in received signal quality between the current time slot of a CDMA channel and the previous time slot. Full and differential CQI reports can be generated as described in TIA/EIA IS-2000.2. Figure 5 shows a block diagram for 〇(1〇^2000 version 0, 11-0〇1 (:11 structure 510. Depending on whether the selection is complete or differential mode, it can be in every 1.25 ms frame ( Or a time slot) generates a 4-bit or 1-bit value for a CDMA channel.

In this embodiment, block encoder 532 encodes the 4-bit CQI value of a CDMA channel with a (12, 4) block code to produce a codeword set having 12 symbols. The block encoder 534 co-codes the N 1-bit CQI values of the N CDMA channels with the (12, N) block code to generate a codeword group having 12 symbols. The rate of the block code (R) is equal to the number of input bits divided by the number of output bits, or the block code of (12,4) is R=4/12 and the block code of (12,N) is r=n /12. Different code rates produce different redundancy! And different received signal qualities are required for reliable reception. Thus, depending on the number N of CDMA channels, different amounts of transmission power can be used for the block of code from block encoder 534. Switch 536 is the output of full mode select block encoder 532 or the output of block encoder 534 for differential mode selection. The Walsh cover unit 538, the adder state 54〇, the signal point mapping unit 542, and the Walsh cover unit 544 are respectively described above for the units 518, 52A, 522, and 524 in FIG. Symbol. The Walsh overlay unit provides an output payout, further processing and transmitting the output symbols on the R_CQICH. The block coding performed by the encoder 534 can express ' y=u»G r ' in a matrix form.

Different block codes can be defined for different N values of 2 to 7 to support up to 7 CDMA channels. The block code for each N value can be selected to achieve good performance, and the performance can be quantified by the minimum distance between the codeword groups. Table 2 lists exemplary block codes for N = 2 to 7. For linear block codes, the block code in Table 2 has the smallest possible distance between the codeword groups.

In the embodiment shown in Table 2, the (12, 2) block code includes a (3, 2) block code followed by a 4 χ sequence repetition. The generator matrix for the (12, 4) block code used in the encoder 534 is the same as the generator matrix for the block codes (12, 143191.doc - 21 - 201004259 4) in the encoders 512 and 532.

Other generation matrices can also be defined and used for the block code of the differential C QI report. Figure 5B shows CQI feedback supporting multiple CDMA channels and is the same as the current 11-€(^1(:11 structure 510 backward compatible example 11-€(^1匚11 structure 530 shown in Figure 5A. If only Receiving a CDMA channel, the full CQI report of the CDMA channel can be processed with the (12, 4) block code, the differential CQI report can be processed with a 12-bit repeat, and the output of the Walsh cover unit 544 will be the same as in FIG. 5A. The output of the Walsh overlay unit 524 is the same. Additional support can be supported by (1) transmitting a full CQI report of the CDMA channel in different time slots and (2) transmitting a differential CQI report of the CDMA channel in the same time slot. CDMA channel. The R-CQICH structure shown in Figure 5B allows for complete and differential CQI reporting of multiple CDMA channels to be recovered with minimal changes to the R-CQICH structure shown in Figure 5A. Block decoding of full CQI reporting can be performed. Demultiplexing of full CQI reporting of different CDMA channels can be performed at the Medium Access Control (MAC) layer. Block decoding of differential CQI reporting can be performed at the physical layer or the MAC layer. Other structures to implement R-CQICH of multiple CDMA channels, and this is in the present invention In the context, for example, a full CQI report for multiple CDMA channels can be block coded and a full CQI report for multiple CDMA channels can be sent in the same time slot. As another example, a CDMA channel can be transmitted in a time slot. A subset of differential CQI reports. As shown in Figure 3, multiple sets of FL and RL carriers can be assigned to a terminal. For 143191.doc -22- 201004259 for each carrier group, as above for Figure 5B As described, the R-CQICH transmitted on the RL carrier in the group can carry the CQI report of the FL carrier in the group. The CQI reports can be sent in various ways. Figures 6A-6E show the R-CQICH Some exemplary transmissions. In these figures, the 'higher box' represents the full CQI report and the shorter squares represent the differential CQI report. The height of the box roughly indicates the amount of power used to transmit the CQI report. The number in each box indicates the FL carrier reported by the f CQI report sent in this box. c Figure 6A shows the transmission of the full and differential CQI reports for two FL carriers 1 and 2 on the R-CQICH. In this example, a full CQI report of fl carrier 1 is sent in a time slot. Sending a differential CQI report for FL carriers 1 and 2 in a certain number of slots, then transmitting a full CQI report for FL carrier 2 in a time slot, and then transmitting FL carriers 1 and 2 in a certain number of slots The differential CQI reports, then sends a full CQI report for FL carrier 1 in a time slot, etc. In general, the Q full CQI report for each FL carrier can be sent at any rate, and the same or different reporting rate can be used. Used for these FL carriers. In one embodiment, a full CQI report is sent in one of the 20 ms frames (e.g., the first) slot, and a differential CQI report is sent in the 15 remaining slots in the frame. The full CQI reporting of FL carriers 1 and 2 may be alternated or otherwise multiplexed as shown in Figure 6A. Figure 6B shows the transmission of the full CQI report of two FL carriers 1 and 2 on the R-CQICH. In this example, a full CQI report for FL carrier 1 is sent in a time slot, then a full CQI report for FL carrier 2 is sent in the next slot, followed by a full CQI report for FL carrier 1 in the subsequent slot, 143191. Doc •23· 201004259 and so on. Figure 6C shows the transmission of the full and differential CQI reports for three FL carriers 1, 2 and 3 on the R-CQICH with repetition factor 2 or REP = 2. In this example, a full CQI report for FL carrier 1 is sent in two time slots before a 20 ms frame, and then a differential CQI for FL carriers 1, 2, and 3 is transmitted in each remaining time slot of the frame. Reporting, then transmitting a full CQI report of FL carrier 2 in two time slots before the next 20 ms frame, and then transmitting a differential CQI report of FL carriers 1, 2 and 3 in each remaining time slot of the frame, The full CQI report of FL carrier 3 is then transmitted in the first two time slots of the subsequent 20 ms frame, and then the differential CQI reports of FL carriers 1, 2 and 3 are transmitted in each remaining time slot of the frame, The full CQI report for FL carrier 1 is then sent in two time slots before the next 20 ms frame, and so on. The differential CQI report can be sent in two consecutive time slots similar to a full CQI report, or can be sent in a single time slot. Figure 6D shows the transmission of a full CQI report for three FL carriers 1, 2 and 3 on an R-CQICH with a repetition factor of two. In this example, the full CQI report for FL carrier 1 is sent in two time slots, followed by the full CQI report for FL carrier 2 in the next two time slots, followed by the complete transmission of FL carrier 3 in the next two time slots. The CQI reports, then sends a full CQI report for FL carrier 1 in the last two time slots, and so on. Figure 6E shows the transmission of the full CQI report for three FL carriers 1, 2 and 3 on the R-CQICH with repetition factor 2 and two handover time slots. In this example, the full CQI report for FL carriers 1, 2, and 3 is transmitted as described above for Figure 6D. However, using the last four time slots 143191.doc -24-201004259 in the 20 ms frame to send a switching slot pattern (denoted as "S" in Figure 6E), the switching slot pattern switches to the new service. Base station information. As shown in Figures 6A-6E, the time division multiplexing of a full CQI report for all FL carriers results in a decrease in the reporting rate of a full CQI report for a given FL carrier as the number of FL carriers in a group increases. For example, if a group includes 7 FL carriers, a full CQI report can be sent every 7 χ 2 〇 ms = 140 ms-times for each -FL carrier. For all carriers

When switching to a new cell, the slot pattern "breakdown" (or replacement) is completely switched when the switch is switched. This breakdown may not affect all FL carriers equally. When switching in the example shown in Figure 6E The slot pattern affects FL carriers 1 and 2 but does not affect FL carrier 3. In the embodiment, a single base station is selected for the feed transmission on the forward link. It can be based on the primary FL carrier, all assigned carriers. Or the _ subset of the FX carrier has been assigned to measure the received signal quality at the terminal to select the single base station. The r_cqich of all RL carriers uses the Walsh coverage of the selected base port and thus points to the same cell. The station avoids the out-of-order transmission of the forward link and its potential adverse effects on the Radio Link Protocol (RLP). In the direction of the direction, usually at the base station controller (BSC) The RLP frame is pre-blocked and then forwarded to the base station for transmission to the terminal. Therefore, MI & π, this is transmitted from a single base station, which avoids the disordered transmission of RLP frames.

3 R-PICH 需要降低前向鏈路上之資料傳輸之反向鏈路額外負擔。 此可藉由向終端機指派包括多個FL載波及單個rL載波之 單個載波組來達成。可在該等多個FL載波上發送資料,且 可在s亥單個RL載波上有效地發送確認及c QI回館。 在某些實例中’可利用多個RL載波。舉例而言,基地台 可能不支援上文描述之新R-ACKCH及R-CQICH結構。在 此情形中,每一FL載波可與支援該FL載波之r_aCkCH及 R-CQICH的一 RL載波相關聯。 在cdma2000版本D中,終端機在R_pICIi上傳輸一導頻以 幫助基地台偵測反向鏈路傳輸。若指派單個RL載波,則在 與此RL載波相關聯之所有FL載波間分擔導頻額外負擔。 然而,若指派多個RL載波且若在每一 rl載波上發送R_ PICH以支援R-ACKCH及R-CqiCh,則導頻額外負擔對於 反向鏈路上之如此低資料速率而言可係顯著的。可藉由使 用一控制保持模式來達成導頻額外負擔之降低。 圖7展示完全及閘控導頻在R_piCH上之傳輸。完全導頻 係每一時槽中之導頻傳輸且被稱為導頻閘控率丨。定義於 cdma2000版本D中之控制保持模式(或簡寫為"Rev D控制保 持模式”)支援1/2及1/4之導頻閘控率。如圖7中所示,閘控 143191 .doc • 26 - 201004259 導頻,時槽之一些t的導頻傳輸,或更具體言之,對 :叫頻閘控率係每隔一個時槽—次的導頻傳輸,且對 :1/4導頻開控率係每四個時槽—次的導頻傳輪。 版本D中,基地台通常在控制保持計時器截 t:Γ由發:—層3訊息來將終端機置於控制保持模式 +例而s,若基地台在特定時間週期中不自終端機接 :任何資料且不向終端機發送任何資料,則基地台可發送 -層3訊息至終端機以將其置於控制保持模式中。新資料 到達基地台或終端機處會觸發退出控制保持模式。若新資 料到達終端機處,則終端機自動退出控龍持模式並開始 在反向鏈路上傳輸完全導頻以及資料。基地台偵測到終端 機退出控制保持模式並解碼與完全導頻—起發送之資料。 若新資料到達基地台處’則基地台首先藉由在1叩咖上 發送-MAC訊息來喚醒終端機。#在控制保持模式令時, 終端機不處理F-PDCH以便節省功率。 ϋ 許多應用均以對稱資料訊務為特徵,且此等應用可能需 要多個FL載波上之多個F-PDCH。結果,需要在多個㈣ 波上發送多個反向導頻以支援多個F_pDCH。除反向導頻 以外,輔助RL載波上之訊務可僅由R_CQICH上之cqi報告 及R-ACKCH上之確認組成。在此情形中,使用控制保持 模式可顯著降低辅助RL載波上之反向鏈路額外負擔。 然而,由於以下原因,Rev D控制保持模式不可直接應 用於輔助RL載波。首先,終端機在Rev 〇控制模式中時, 不對F-PDCH進行解碼。其次,要求終端機在R_ACKCH上 143191.doc -27- 201004259 進行傳輸之前退出Rev 0控 “ s… 持权式,且需要來自基地 口…“,以使終端機返回控制保持模 機在r-ackch上進行值終R主仏 母人、,、如 4仃傳輸時均必須發送層3訊息係不良 的。此外,由於基地台在抻去丨 在技制保持计時器截止(其通常約 為數百耄秒)後發送層3气自, 路上傳輸完全導頻。…此在此時間期間於反向鍵 中,一”輔助,|控制保持模式經定義用於輔助 載波上。在-實施例中,輔助控制保持模式在以下方式 中不同於Rev D控制保持模式: •終端機在輔助控制保持模式時可處難PDCH, •終端機可在不退出辅助控制保持模式的情況下,於R_ ACKCH上傳輸確認, •若F-PDCH得以成功解碼’則終端機可自動在 ACKCH上傳輸完全導頻及確認,及 •終端機可在完成R-ACKCH傳輸後重新開始導頻閘 控。 亦可用不同及/或額外特徵來定義輔助控制保持模式。 為降低反向鏈路上之導頻額外負擔,可在主壯载波上使 用Rev D控制保持模式,且可在每一輔助壯載波上使用辅 助控制保持模式。控制保持模式的兩個版本可支援多载波 操作之多個RL載波的有效操作。 ' 在-實施例中’可為每一 RL載波獨立地定義控制保持模 式。可能有以下情形: 、 •主要RL載波在作用中模式下,且任何數目之輔助壯 I43191.doc -28. 201004259 載波可在控制保持模式下。終端機可處理輔助RL載波之F_ PDCH ’且可在不離開控制保持模式的情況下,於R_ ACKCH上進行傳輸。 •所有RL載波在控制保持模式下。終端機在不離開控制 保持模式的情況下’不處理F_pdch且不在R-ACKCH上進 行傳輸。此係功率節省模式。3 R-PICH requires an additional burden on the reverse link for data transmission on the forward link. This can be achieved by assigning a single carrier group comprising a plurality of FL carriers and a single rL carrier to the terminal. The data can be transmitted on the plurality of FL carriers, and the acknowledgment and cQI can be effectively transmitted on a single RL carrier. In some instances, multiple RL carriers may be utilized. For example, the base station may not support the new R-ACKCH and R-CQICH structures described above. In this case, each FL carrier can be associated with an RL carrier supporting the r_aCkCH and R-CQICH of the FL carrier. In cdma2000 version D, the terminal transmits a pilot on R_pICIi to help the base station detect reverse link transmission. If a single RL carrier is assigned, the pilot extra burden is shared among all FL carriers associated with this RL carrier. However, if multiple RL carriers are assigned and if R_PICH is transmitted on each rl carrier to support R-ACKCH and R-CqiCh, the pilot extra burden can be significant for such low data rates on the reverse link. . A reduction in the additional burden of the pilot can be achieved by using a control hold mode. Figure 7 shows the transmission of the full and gated pilot on R_piCH. The full pilot is the pilot transmission in each time slot and is referred to as the pilot gating rate 丨. The control hold mode (or abbreviated as "Rev D control hold mode) defined in cdma2000 version D supports 1/2 and 1/4 pilot gating rates. As shown in Figure 7, gate control 143191 .doc • 26 - 201004259 Pilot, pilot transmission of some t-time slots, or more specifically, pairs: called frequency gating rate is every other time slot-time pilot transmission, and: 1/4 lead The frequency control rate is every four time slots - the first pilot transmission. In version D, the base station usually controls the timer to intercept t: Γ by sending: - layer 3 message to put the terminal into the control hold mode + For example, if the base station does not connect to the terminal during a certain period of time: any data and does not send any data to the terminal, the base station can send a layer-3 message to the terminal to place it in the control hold mode. When the new data arrives at the base station or the terminal, the exit control hold mode will be triggered. If the new data arrives at the terminal, the terminal will automatically exit the control mode and start transmitting the complete pilot and data on the reverse link. Detecting terminal exit control hold mode and decoding with full pilot From the information sent. If the new data arrives at the base station, the base station first wakes up the terminal by sending a -MAC message on the coffee machine. # When controlling the hold mode command, the terminal does not process the F-PDCH to save Power ϋ Many applications are characterized by symmetric data traffic, and these applications may require multiple F-PDCHs on multiple FL carriers. As a result, multiple reverse pilots need to be sent on multiple (four) waves to support multiple F_pDCH. In addition to the reverse pilot, the traffic on the secondary RL carrier can consist only of the cqi report on the R_CQICH and the acknowledgment on the R-ACKCH. In this case, using the control hold mode can significantly reduce the secondary RL carrier. The reverse link has an additional burden. However, the Rev D control hold mode cannot be directly applied to the secondary RL carrier for the following reasons. First, when the terminal is in the Rev 〇 control mode, the F-PDCH is not decoded. Second, the terminal is required. Exit R_ACKCH on 143191.doc -27- 201004259 before exiting Rev 0 control "s... hold-on, and need to come from the base port...", so that the terminal returns to control to keep the die machine on r-ackch In the end of the value R main parent, if, for example, 4 仃 transmission must send Layer 3 message system is bad. In addition, because the base station is in the 丨 丨 技 technical maintenance timer cutoff (which is usually about hundreds After the leap second), the layer 3 gas is transmitted, and the complete pilot is transmitted on the road.... During this time, in the reverse key, an "auxiliary, | control hold mode is defined for the auxiliary carrier. In an embodiment, the auxiliary control hold mode is different from the Rev D control hold mode in the following manner: • The terminal can be in a difficult PDCH in the auxiliary control hold mode, • the terminal can be in the case of not exiting the auxiliary control hold mode , transmit acknowledgment on R_ ACKCH, • if F-PDCH is successfully decoded 'the terminal can automatically transmit full pilot and acknowledgment on ACKCH, and • terminal can restart pilot control after R-ACKCH transmission is completed . Different and/or additional features may also be used to define the auxiliary control hold mode. To reduce the extra pilot burden on the reverse link, the Rev D control hold mode can be used on the primary carrier and the secondary control hold mode can be used on each of the secondary strong carriers. Two versions of the control hold mode can support the efficient operation of multiple RL carriers for multi-carrier operation. The 'in the embodiment' can define a control hold mode independently for each RL carrier. There may be the following situations: • The primary RL carrier is in active mode, and any number of secondary swells can be in control hold mode. The terminal can process the F_PDCH' of the secondary RL carrier and can transmit on the R_ACKCH without leaving the control hold mode. • All RL carriers are in control hold mode. The terminal does not process F_pdch and does not transmit on the R-ACKCH without leaving the control hold mode. This is the power saving mode.

The R-REQCH terminal can send various types of information to the base station on R_rEqCH. The trigger for transmitting RREQCH messages in cdma2000 version D can also be used as a trigger for transmitting R_REQCH messages for multi-carrier operation. In one embodiment, the terminal transmits an R_REQCH message on the primary RL carrier to convey information about the service to the base station. A single buffer can be maintained for each service of data transmission on all RL carriers. Information about the service may include buffer size and watermark crossing. In one embodiment, the terminal transmits R_REQCH messages on both the primary and secondary RL carriers to communicate the power reserve (header 〇〇m) of the RL carriers. The power reporting trigger for each rl carrier can be used to convey the power reserve space of the RL carrier. 5. Scheduling Winter end machine scheduling can be performed in a variety of ways for data transmission on the forward and reverse links. The schedule can be centralized for multiple carriers or distributed for each carrier. In one embodiment, the centralized scheduler is a data transmission machine that spans multiple carriers. The Chinese scheduler supports a flexible scheduling algorithm. The scheduling algorithm can utilize CQI information across all carriers. Improve throughput and / or provide the desired quality of service (QOS). In another embodiment, 143191.doc -29-201004259 provides a distributed scheduler per carrier, and the distribution schedule schedules the terminals on the carrier. The distributed schedulers of different carriers can operate independently of each other and can reuse the existing scheduling algorithms of cdma2000 version D. A single channel plug-in at the base station or multiple carriers supported by multiple channel plug-ins can be assigned to the terminal. If multiple 叮 carriers are handled by different channel plug-ins, there is a (4) plug-in communication delay that can be on the order of a few milliseconds. Even if this delay is small 'but it is usually greater than 丨.25 ms, h25 ms is used to resolve _ ackch, and it is better to decode R_CQICH and schedule the time on F_PDCH. If multiple channel plug-ins are used for different FL carriers, centralized scheduling writes can cause additional scheduling delays. This extra delay consists of two components. First component

RLP is pre-packaged at the BSC and is attached with an additional burden. Each RLp frame including the MUX extra load contains 3 84 bits in cdma2〇〇〇 and is numbered by 12-bit number. Identification: assigns 12 bits to the RLP frame number with the 32〇〇〇^^^ header, which is used to reassemble the RLP frame at the terminal. Considering the smaller RLp frame size, The sequence space may not be sufficient at inter-rates, such as the rate achievable in a multi-carrier configuration. To support high data rates with existing RLPs, the RLP frames can be pre-segmented for reuse. The additional 12-bit sequence space of the segmented RLP frame. Since the RLp frame does not need to be pre-packaged, the sequence space is not a problem on the reverse link. The call setup procedure for multi-carrier operation can be implemented as follows.

As shown in FIG. 3, each group may include at least one FL carrier and one RL carrier. The terminal can receive the packet on the (the) FL carrier in each group and can send an acknowledgment of the received packet via the (the) RL carrier in the group. The terminal can also transmit the CQI report of the (%) FL carrier in the group via the 1 carrier in each group. One FL carrier in each group can be designated as the group primary FL carrier. The terminal can receive signals from the RL carriers in each group via the group primary FL carrier. Figure 9 shows an embodiment of a process 9 for transmitting an acknowledgment. The terminal receives packets transmitted via a plurality of forward link (FL) carriers on a plurality of data channels (e.g., 'F_PDCH) (step 912). The terminal determines the confirmation of the packet received on the data channel (step 914). The terminal uses the orthogonal code (e.g., Walsh code) assigned to each of the data channels to channel the acknowledgment of the data channel to generate a sequence of symbols for the data channel (step 916). The terminal copies the symbol sequence of each data channel a plurality of times (step 918). The replicated symbol sequence of the final plurality of data channels produces a modulation symbol for the acknowledgment channel (e.g., two ACKCHs) (step 920). The number of data channels can be configurable. If, for example, it is backward compatible with edma2_version D and only an acknowledgment is sent for a data channel, an all zero or all-one orthogonal code can be used. If the number of channels is less than the first value (for example, 4), then the first length can be used (for example, four codes & orthogonal codes. 143191.doc -33 - 201004259 if the data channel is θ H 4 or If it is greater than the first value, an orthogonal code having a second length (for example, eight 彳m μ μ \ , ', , and month) may be used.

The terminal channelizes the code block (1 022) with the orthogonal code of the selected base station. The terminal then transmits the stone horse block (1024) on the kiss channel during a particular time interval. . Figure " shows an embodiment for reducing the extra burden of pilots such as multi-carrier operation. The terminal operates in a control hold mode that allows transmission of the challenge pilot (step 1112). The terminal receives the data channel (e.g., F-PDCH) transmitted on the forward link when in the control hold mode (step 143191.doc '34-201004259 1114). If no other transmissions are sent on the right reverse link, the terminal transmits a gating pilot on the reverse link (step 1116). If the transmission is being transmitted on the reverse link, the terminal transmits the full pilot on the reverse link (1118). For example, the terminal can generate an acknowledgment of the packet received on the data channel, send the acknowledgment and the complete pilot on the reverse link, and restart the transmission gate after completing the transmission of the acknowledgment on the reverse link. Control pilot. The terminal exits the control hold mode in response to an exit event, which may be coupled to C" a signal to exit the control hold mode, transmit data on the reverse link, etc. (step 1 120). 8 through 11 illustrate a process in which a terminal is executed for multi-carrier operation. The base station performs complementary processing to support multi-carrier operation. Figure 12 shows a block diagram of an embodiment of a base station 11 and a terminal unit 12A. For the forward link, at the base station 11, the encoder 121 receives the traffic data and signals for the terminal. The encoder 121 processes (e.g., encodes, interleaves, and symbol maps) the traffic data and signals, and generates various forward link channels for, for example, F-PDCH, F-PDCCH, F-ACKCH, and F-GCH. Output data. Modulator 1212 processes (e. g., channelized spread spectrum and scramble) for output data for various forward link channels and produces output chips. Transmitter (TMTR) 1214 conditions (e.g., converts to analog, amplifies, filters, and upconverts) the output chips and generates a forward link signal that is transmitted via antenna 1216. At terminal 120, antenna 1252 receives the forward link signals from base station 11 and signals from other base stations and provides the received signals to receive state (RCVR) 1254. Receiver 1254 adjusts (eg, tears, 143191.doc -35-201004259 large, down-converted, and digitized) to receive the data samples. Demodulation transformers (Demod) 1256 process (e.g., VV) such as descrambling, despreading, and de-channeling the data samples and providing symbol estimates. In one embodiment, the receivers 12 5 4 and/or Or demodulation 5| 1 2 5 6. The core 56 performs filtering to pass all phase waves. The decoder 1258 processes (eg, 'demapping, deinterleaving, and decoding') the symbol estimates and is used by the base station 11() The traffic data and signals sent to the terminal i2Q provide decoded data. The demodulation transformer 1256 and the decoder 1258 can perform demodulation and decoding separately for each FL carrier. ... On the reverse link, at the terminal 12 The encoder 127 processes the traffic data and signals (eg, 'acknowledgement and CQI reports') and generates output data for various reverse link channels such as L PDCH, R-ACKCH, R_CQICH, R piCH, and r reqch . The demodulation processor processes the output data and produces an output stone. The wheeler 1274 adjusts the output chips: generates a reverse link signal, and transmits the reverse link signal via the antenna 1252. At station 110, the reverse link signal is received via antenna 1216, via receiver 1 The 230 is adjusted, processed by the demodulation transformer 1232, and further processed by the decoder 1234 to recover the data and signals transmitted by the terminal device 12. The controller/processors 122 and 126 指导 respectively guide the base station i 1 and the terminal The operations are performed at the machine 120. The memories 1222 and 1262 respectively store data and code for the controllers/processors 1220 and 1260. The scheduler 1224 can assign FL and/or RL carriers to the terminal and can be forward and The data transmission on the reverse link schedules these terminals. & The multi-carrier transmission technique described in this paper has the following characteristics: • Multi-carrier forward link compatible with the Rev D forward link - no change 143191.doc -36- 201004259

The transmission techniques described herein can provide various advantages. First, these technologies allow cdma2000 version D to support multiple carriers using only or primarily software/firmware upgrades. A relatively small number of changes are made to some RL channels (eg, R-ACKCH and R-CQICH) to support multi-carrier operation. These changes can be handled by software/firmware upgrades at the base station so that existing hardware such as channel plug-ins can be reused. Second, higher peak data rates can be supported on the forward and reverse links. The third 'using multiple F-PDCHs on multiple FL carriers improves diversity, which improves q〇s. The flexible carrier architecture allows data rates to increase with the advancement of VLSI technology.
