Description

1375426 IX. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates generally to the field of wireless communications and, more particularly, to the field of error recovery in wireless communication systems. [Prior Art] In the past two decades, cellular phones have been popularized. At the same time, significant advances in wireless technology have enabled cellular phones to have more features, better reception, higher bandwidth, and increased system capacity. Today's digital and packet-based wireless systems are much more advanced than the original digital wireless systems and will be more promising in the future. The first popular digital wireless systems included GSM (Global System for Mobile Communications). In the early 1990s, GSM was introduced throughout Europe as a second generation (2G) wireless system and now operates in more than 100 countries around the world. In recent years, GSM developers have introduced a number of enhancements and improvements built on GSM voice services to add a variety of data and voice capabilities to the system. With this improvement, GSM has evolved into a system that provides a large number of enhanced digital voice and data telephony services (eg, Internet access, multimedia and video). GSM enhancements include GPRS, EDGE and GERAN. The GPRS (Common Packet Radio Service), first introduced in the mid-1990s, is based on GSM-based TDMA wireless packet-based network architecture. GPRS is based on the GSM radio interface (i.e., the interface between the terminal and the base station) and is based on the GSM radio interface structure of the time slots and TDMA (Time Division Multi-Direction) frames. GPRS provides users with increased bandwidth and can be dynamically configured between voice and data as needed. 105485.doc More than 1375426 slots provide operators with more efficient use of bandwidth. This allows the GPRS link to use one to eight slots available per GSM frame at speeds up to 22_8 kb/s per slot. In addition, the number of time slots for the GPRS uplink and downlink can be configured independently of each other. GPRS uses four different coding schemes (CS1 to CS4), each of which is a phase-modulated coding scheme using Gaussian Minimum Shift Keying (GMSK) modulation. GPRS supports X.25, a low-speed packet transmission protocol popular in Europe. The construction of GPRS is one step towards the construction of the EDGE system (GSM Evolutionary Data Enhancement Technology). EDGE is an enhancement to GPRS that uses the same spectrum configuration as existing GSM systems such as GSM900, GSM 1800 and GSM1900. EDGE is characterized by nine encoding schemes, four of which use GMSK modulation and five of which use eight-phase shift keying (8PSK) modulation. The four EDGE GMSK coding schemes (MCS1 to MCS4) are similar to the four GPRS coding schemes (ie, CS1 to CS4). The other five EDGE encoding schemes (MCS5 to MCS9) use 8PSK modulation to produce a three-bit block for each change in the carrier phase. The use of 8PSK modulation approximately triples the GPRS peak data rate. Another enhancement to GSM, GERAN (GSM Edge Radio Access Network) supports the EDGE network as an alternative radio access network compatible with the 3G GSM Evolutionary Core Network (CN). The GERAN architecture allows the CN to connect to the A, Gb, and Iu interfaces. GERAN is built to deliver packet-based instant wireless services, including voice, multimedia, video and internet access. Although the coding scheme has been improved and features have been enhanced, errors have occurred from time to time in the wireless system due to poor reception conditions. In order to recover from reception errors, EDGE and its associated enhancements and services provide an incremental redundancy 105485.doc 1375426 error recovery scheme. When the transmission fails due to (4) an error, the action reception H sends an automatic repeat request (ARQ) back to the base station. Respond to the

The ARQ base station transmits the failed transmission using a different coding scheme. The error is rectified by combining the initial message with a second version of the message retransmitted using a different encoding scheme. Such a conventional error recovery system increases the likelihood of recovering a failure message, but it is delayed by sending the ARQ back to the message source with a request to retransmit the otherwise encoded version. SUMMARY OF THE INVENTION In a known example, a method for providing redundancy for error recovery in multi-carrier wireless communication is provided. The method includes encoding an initial version of the information to be transmitted with a first encoding scheme, and encoding a redundant version of the information to be transmitted with a second encoding scheme. The method further includes transmitting an initial version of the information encoded by the first coding scheme, the initial version being transmitted on the f-carrier; and transmitting a plurality of versions of the information encoded by the second coding scheme, the redundancy version Part of the beta acknowledgment to ν is uploaded on the second carrier (4).

[Embodiment] FIG. 1A depicts a typical wireless network architecture that supports a mobile station and a client device in accordance with various embodiments 105485.doc 1J/5426. 1A is a block diagram illustrating the relationship between a typical wireless component of the circuit 110 and its components and the illustrative embodiments. Downstream of the network 13 wireless systems typically have three broad categories of components: a core h controller (SGSN 1〇2), a base station (10) C/BTS just), and a wireless mobile unit 120. Although the network controller in the figure is labeled as a Feeding GPRS Support Node (SGSN) H) 2, in some embodiments it may be in other shapes or referred to as its name, for example, a mobile switching center (Μ%) ). Typically, φ SGSN is the core network entity that handles the packet-switched connection, and the MSC is the core network entity of the processing circuit/switched connection. This figure depicts the base station controller/base transceiver (BSC/BTS). 1〇4, which may sometimes be in other forms or may be referred to as other names, such as a base station system (BSS). The mobile unit 120 has many different names, for example, a cellular phone, a mobile station, a wireless handset, a pocket (1), etc. The scope of the present invention covers such other terms as, for example, Msc ' And the like. The wireless network is merely exemplary and may include any system that allows communication with mobile wireless § devices, such as wireless (〇ver_the_air) communication with each other and/or connected via wireless network 110. A mobile unit 120 for wireless communication between components. These mobile units 12, including but not limited to one or more cellular telephones 112, PDAs (personal digital assistants), paging machines 116, navigation devices 118, wirelessly connected computers 128, music or video content download unit a, wireless game device m, inventory unit 126 or other similar type of wireless device. Honeycomb or other wireless telecommunication service can be through the fixed network π 〇 data link Carrier network communication of a road or other network link, wherein the fixed network 130 can be a PSTN (Public Switched Telephone Network), 105485.doc 1375426 ISDN (full Physical service digital network), Internet, LAN (local area network), WAN (Wide Area Network) or other such network. Between the SGSN 102 and the fixed network 130 can be implemented using the Signal Transmission System 7 (SS7) protocol. Signal transmission. The SS7 protocol is used for trunk signal transmission in ISDN and is widely used in current public networks. Wireless network 110 controls messages or other information sent to SGSN 102, which is typically sent as a data packet. The SGSN 102 is typically coupled to one or more BSC/BTSs 104. The SGSN 102 functions in the wireless network 110 in a manner similar to a standard switching node of a terrestrial communication line network (e.g., PSTN or ISDN). The SGSN 102 includes ( For example, logic in processor 106 for managing and controlling mobile unit 120. Processor 106 or other logic manages and controls call routing, such as mobile unit 120 temporarily stored at a BSC/BTS 104 base station associated with SGSN 102, A staging, verification, location update, handover, and/or coding scheme. Another typical wireless network is the Operations and Service Center (OMC), which can be viewed as part of the processor 106 or other logic. The MC organizes the operation and setup of the wireless network. In a manner similar to the network 130, the SGSN 102 is connected to a number of BSC/BTSs 104 by a network configured for data transfer and/or voice information. In the wireless network 110, communications to various SGSNs 102 and BSC/BTSs 104 and communications from various SGSNs 102 and BSC/BTSs 104 typically use terrestrial communication line networks, the Internet, and/or the public switched telephone network. Road (PSTN). The base station subsystem (including the BSC/BTS 104) controls the radio link with the mobile unit 120. Within the base station subsystem, the BSC/BTS 104 has one or more transmitters and receivers to transmit 105485.doc -10- 1375426 information to and receive information from the mobile unit 120. The BSC/BTS 1.4 transmits wireless data messages or other information to the 动τ moving unit 12 (such as the cellular telephone 112) by a wireless (〇ta) method. The BSC/BTS 104 communicates with the mobile unit 12 via the interface, and the surface is also not audible for the radio interface or the radio key (4). The circle m depicts the details of the BSC/BTS 104 and the wireless mobile device 12A. Each base 2 says (4) that the code includes the code, and the protocol or coding scheme of the read wheel (4) encodes/decodes the information. The base platform squad also includes a processor 101 capable of executing or controlling common programs and processes involved in wireless communication; and can also be configured to include - memory 1 〇 3 It is used to store various protocols, common programs, processes, or software to be used to perform wireless communications. For example, 'memory 1G3 can store _ or multiple frequency strategies for use with various mobile units 12G. The transmission strategy includes information on (4) the redundancy of the transmission, the number m used to transmit the redundancy version associated with the initial version, and any coding scheme or agreement to be used for transmission and reception of the wireless communication. This information can also be stored in the memory 1〇8 of 8 coffee 1〇2 and transferred to the base station BSC/BTS 1〇4 as needed. An embodiment of the mobile unit (3) as seen in the details of the cellular telephone 112 shown in Figure (7) can be configured to include - processor 107, memory 109 and encoder/decoder (1), which performs similar to BSC/ The function of the corresponding part of the BTS 104. The mobile unit 12A may also have an antenna U3, a receiver area 115, and other electronic devices known to those skilled in the art for wirelessly receiving information. It may need to be monitored and received simultaneously or overlaid with multi-carrier wireless. Different transmissions in the system. / Wireless network 110 includes at least one local location register (HL Magic and Mass Access 105485.doc -11 · 1375426 Guest Location Register (VLR) (not shown), which provides information for call routing and roaming The HLR, which is typically centralized within the wireless network 110, contains management information for the various mobile units 120 that are temporarily stored in the wireless network 110, along with the current location of the mobile unit 120. Although logically there is only one HLR per network, However, the HLR can be constructed as a distributed repository. Each SGSN 102 of the wireless network 110 has a visitor location register (VLR) associated with it stored in the memory 108 of the SGSN/MSC 102. The VLR storage is selected from the group consisting of Management information of the centralized HLR for call control and user service for each mobile unit 120 currently under the control of the SGSN/MSC 102. There are usually two other types of verification and security in the wireless network 110. Memory: Device Identification Register (EIR) and Authentication Center (AuC). EIR is a database of all active mobile units 120 associated with the network. Mobile unit 120 in its EIR with its unique International Mobile Equipment Identity It is identified by IMEI. The AuC contains a copy of the keys stored in the various mobile units 120 for authentication and encryption via the radio channel. It should be noted that the SGSN/MSC 102 itself does not contain information about the particular mobile unit 120. The information of unit 120 is typically stored in the HLR and VLR. The mobile unit 120 is typically equipped with a subscriber identity module (SIM), which is a smart card for identifying the mobile unit 120, thereby enabling the mobile unit 120 to be at the terminal. Making and receiving calls and receiving other subscription services. The IMEI of the wireless unit 120 stored on the SIM card uniquely identifies the particular mobile unit 120. The SIM card also stores an International Mobile Subscriber Identity (IMSI), which is used to Identify the user of the system, along with a copy of the key used for verification from the AuC scratchpad, and other information about the Security, Identification and Communications Association 105485.doc -12- 1375426. Each action unit 12 is stored with (or download) - or software applications - such as games, news, inventory monitors, and classes: programs. Action unit 120 includes configurable - or Logic in the form of a plurality of processing circuits that execute resident configuration logic, microprocessors, digital signal processors (DSPs), microcontrollers or hardware, software, and/or processors and logic Other similar combinations of details are configured to perform at least the operations described herein. Individual operations. Wireless communication between unit U0 and BSC/BTS 1〇4 may be based on any of a number of different technologies, such as (3) Hidden ((4) multi-directional proximity), TDMA, FDMA (frequency-multidirectional proximity), 〇FDM (orthogonal frequency multiplex) and any use of coding techniques (such as GSM or other similar in communication or data networks) A system of hybrids of wireless protocols, as long as the system or protocol provides simultaneous multi-channe (eg, multi-carrier) communication. A carrier can be considered as a specific frequency (or frequency band) at a particular point in time. The concept of a channel includes a carrier, but can also be broadly understood to include spatial dissimilarity (e. g., different communication links) or other similar types of communication paths that the receiver can receive simultaneously. Data communication typically occurs between mobile unit 120, BSc/BTS 1〇4 and SGSN 102. The SGSN 102 can be connected to multiple data networks such as carrier networks, PSTNs, the Internet, virtual private networks, and the like to allow the client devices to access a wider communication network. As previously mentioned, in addition to voice transmission, data may also be transmitted to the customer premises equipment via SMS or other OTA methods known in the art. Figure 2A depicts an RLC/MAC block that configures information about the structure of the time slot and frame. GSM is used herein as an illustrative system to explain the 105485.doc 1375426 RLC/MAC concept and frame structure. Embodiments of the invention may also be incorporated into other wireless systems. GSM uses this scheme to configure its available radio spectrum: This scheme combines TDMA (Time-Division Multi-Direction) and FDMA (Frequency-Division Proximity). GSM uses the FDMA concept to divide its available bandwidth carrier frequency at 200 kHz intervals. Typically, each base station is assigned a number of such carrier frequencies. The timing (a TDMA concept) is achieved in GSM by dividing the individual carrier frequencies into time slots 205, as shown in Figure 2A. The GSM time slot lasts 15/26 ms (0.577 ms). The terms "time slot" and "clustering cycle" can be used interchangeably. Each of the GSM TDMA frames 207 that lasts 4.615 ms has eight time slots 205 of 0.577 ms. The GSM physical channel can be thought of as a time slot 205 for each TDMA frame 207. For example, the physical channel may consist of the individual TDMA frames shown in Figure 2A, x" to "x+3,, and the time slot "〇" (2〇5) in the sequence (207). The wireless link on the channel may occupy the same time slot 205 (e.g., time slot 0) in each of a series of TDMA frames 207 for the duration of the link or at least until a new channel is assigned. The channel can be a dedicated channel configured for a call to a particular mobile station' or can be a common channel used by a large number of mobile stations on an onan-needed basis idle mode. In the GSM system, the frame scheme can be set differently depending on the functions performed. One such channel is a full rate G SM traffic channel (TCH). The TCH carries voice and data traffic and can be grouped into a multi-frame consisting of 26 frames. That is, each TCH multiframe includes 26 TDMA frames. (Multi-frame can be defined as containing a different number of frames than 26 frames; for example, 52 multi-frames of the pivot.) Each 26-frame multiframe is 120 ms long (120 ms/ 26=4.615 ms=—frame). Therefore, a multi-frame (120 ms) 105485.doc • 14- 1375426 divided by 26 frames, divided by eight burst periods per frame equal to one burst period (time slot), which is about 0.577 ms. The 26 frames in the GSM message box include 24 message frames, one frame dedicated to the Slow Associated Control Channel (SACCH), and another frame that remains undefined at this time. In order to provide some time between the mobile station transmission and its reception, the uplink TCH is separated from the downlink TCH by three burst periods. In addition to the full rate TCH (TCH/F), there is also a half rate TCH (TCH/H). There is also an eight rate TCH, sometimes referred to as a Standalone Dedicated Control Channel (SDCCH), which is primarily used to transmit location update information. The use of a half rate TCH effectively doubles the system capacity compared to communication using a full rate TCH because for full rate TCH/F, TCH/H speech coding is performed at 7 kbp instead of 13 kbp. 2A shows an RLC/MAC 201 block that maps to a radio block 203 and then maps to four time slots 205 of four consecutive TDMA frames 207 belonging to the GSM multiframe. The Layer 2 transport protocol for GPRS/EDGE is RLC/MAC. RLC (Radio Link Control) is a sublayer of the radio interface that provides reliability; while MAC (Media Access Control) is the lower of the two sublayers of the data link layer and handles access to the shared medium. RLC/MAC provides the control and collaboration necessary for GPRS wireless communications. In GPRS, an RLC/MAC 201 block is transmitted as part of a radio block 203. The radio block 203 is transmitted via four consecutive GPRS time slots 205 transmitted over a GPRS time slot frame (e.g., the aforementioned 24 hour slot frame or possibly a 52 hour slot frame). The internal time slot distance between each of the four time slots 205 containing the radio block is 8 time slots, or the length of a TDMA frame 207. The contents of the four time slots 205 are only the RLC/MAC 201 block itself. Four 105485.doc -15 - 1375426

The sequence of parts. Since GPRS does not provide any incremental redundancy for error recovery, there is no incremental redundancy between the four time slots 205 and it does not contain redundant information for any radio block data 203. However, incremental schemes are provided in edGE where redundant versions are transmitted at different points in time on the same carrier. Figure 2B illustrates an exemplary incremental redundancy scheme. In EDGE within the rlc/MAC protocol, incremental redundancy can be employed at layer 2. If no error is detected in the RLC/MAC block sent to the mobile station, the RLC/MAC block is passed to the next layer for processing. For example, if no error is detected in Figure 2] 8 < First Transmission 211 (RLC/MAC Block Coded by MCS-6), it is passed to the next layer without retransmission, and the block is retransmitted. 213 and 215 were not sent. In the current EDGE construction, the mobile device sends an automatic repeat request (ARQ) to the base station for the RLC/MAC block in which the negative acknowledgment is detected. In response to the ARQ, the base station retransmits the RLC/MAC block using different Mcs (modulation and coding schemes). The (these) retransmission blocks are typically reassembled with the first block' to enhance redundancy and increase the chances of recovering the error free RLC/MAC block. This situation is depicted in Figure 2B*, assuming an error is detected in the first transport block 211, causing arq to be sent back to the base station. In response to the ARQ, the same information is again transmitted in retransmission blocks 213 and 215, this time encoded in MCS-3. Since the retransmission (MCS-3) uses different modulation and coding schemes compared to the first transmission (mcs6), two new transmission blocks are used instead of one retransmission block to transmit the data. In the conventional example, the retransmission section uses the -retransmission section 2丨3 and the second retransmission section 215 to transmit the material. 105485.doc 16 1375426 Most embodiments of the present invention encode a redundancy version using a different coding scheme than the original version (e.g., 'different MCS'). This provides incremental redundancy, rather than providing redundancy by simply transmitting a redundancy version encoded in the same scheme. However, some embodiments of the present invention may encode the redundancy version using the same Mcs if it is possible to generate an error due to reception conditions associated with a particular carrier. The conventional embodiment of EDGE does not use the same RLC/MAC block as the initial transmission to retransmit the negative acknowledgement because the conventional embodiment of edge uses the same carrier transmit redundancy version as the initial version. Errors caused by the main disadvantages of the radio interface are highly likely to produce similar results with errors. There are some limitations to the choice of the coding scheme when S uses different MCS for the redundancy version. The MCS coding scheme is classified by family (eg, group a, B, or C). If a different MCS is used for the redundancy version, it should be selected from the same "family" as the MCS used in the first transmission. For example, Figure 2B depicts a Mes_6 RLC/MAC block 211 of a negative acknowledgement being retransmitted using two MCS-3 blocks 213 and 215. Since both MCS-6 and MCS-3 belong to Group A, this is suitable. Furthermore, when lower MCs are used, 'retransmission of RLC/MAC blocks may require more radio blocks than the first transmission' because the same information will be retransmitted at a lower coding rate. This is depicted in Figure 2B, which shows that the first transmission 211 being transmitted in a radio block with MCS-6 requires two radio blocks 213 and 215 due to the retransmission being performed with Mcs_3. As shown in FIG. 2B, the time interval between the first MCS_6 transmission 211 and the first-Mcs_3 transmission 213 is greater than the two rivers (: 105 485.doc _ time interval between the 5-3 transmissions 213 and 215. The transmission is redundant on the same carrier. In one of the remaining versions of EDGE, in the incremental incremental embodiment, the interval before the transmission of the redundancy version is due to the acknowledgment procedure in EDGE; for example, the ARQ being sent back to the base station. Negation in EDGE The answering procedure is based on RLe, so the relative consumption is increased in the number of instances in which the EDGE is incremented. In the case of the first transmission, the response signal (not shown) needs to be sent back to the transmitter before the retransmission is started. The duration of this time interval depends on the embodiment, and mRQ is not necessarily set based on RLC/MAC, so embodiments of the present invention are limited to this side g. Instead, the redundancy version is used as a predetermined scheme (eg, in response to the transmission) - Partial transmission, encoded or otherwise processed, is transmitted instead of in response to ARQ. In some embodiments, the redundancy version may be transmitted within the same transmission time limit as the initial version according to a predetermined transmission strategy. , but it is not necessary to time the transmission of the initial and redundant versions. In this paper, the transmission time limit ^ is any time after the initial version starts transmission until the next initial version starts, assuming the next = version Not delayed due to reception errors. In other embodiments, the transmission time limit may be defined as a predetermined value that is less than the time taken to receive the (four) transmitter after receiving the error. The transmission policy is defined as being used for A number of versions of the predetermined plan for sending the version with the initial version (4) and (4) for the initial version and - or multiple redundant redundancy schemes. Although some embodiments send after the initial version =: It is the same redundancy version of the initial version of the other 6H within the same transmission time limit as the initial version, as discussed in conjunction with Figures 3-4 and 6. 105485.doc • 18· 1375426 Figure 3 depicts one via the present invention The carrier transmission system transmits the radio block 303. This figure is an exemplary embodiment of the present invention, which is used for GERAN or other multi-carrier based architecture and based on 〇fdm (orthogonal frequency multiplication) Enhanced incremental redundancy error recovery for wireless systems introduced by the present invention. There are multiple carrier wireless transmission systems that can be used in the present invention, including multi-carrier CDMA, spread spectrum communication systems, or 〇FDM in various formats. Others can be used. A communication system, as long as it is characterized by simultaneous multi-channel use; for example, a multi-carrier system, such as multi-carrier GPRS (MC_GpRS). The present invention allows for the development of such multi-channel (e.g., multi-carrier) architectures to implement transmission structures. Improvements, for example, to improve the MC-GPRS transmission structure. Figure 3 depicts an embodiment showing a mapping to a radio block 3〇3 and then to one of the four time slots 305-311 (:/] ^ eight (: block 301, the four time slots 3 〇 5_311 belong to four parallel TDMA frames of four parallel carriers. The mobile terminal can receive the radio block 303 by monitoring all four carriers while it is waiting to transmit the RLC/MAC block. In an EDGE system, individual radio blocks are transmitted at different frequencies (frequency hopping systems), but the terminals in the conventional EDGE embodiment are only required to monitor one frequency at any particular point in time. According to the present invention, radio blocks can be wirelessly transmitted via a multi-carrier transmission system to reduce transmission time 'because the radio blocks can be in a single-duration (eg, a tight time interval, a single time slot group or an adjacent time slot) transmission. Thus, the transmission time for a particular amount of data using embodiments of the present invention is significantly faster than the transmission time of the conventional GPRS transmission structure depicted in Figure 2A. Comparing the embodiment shown in FIG. 3 with the embodiment shown in FIG. 2A, the radio block of the multi-carrier system 105485.doc 1375426 can be transmitted in parallel on several carriers as shown in FIG. 3, instead, the conventional system will be radio. The blocks are distributed over the duration of the three TDMA frames (actually three TDMA frames plus one time slot, or 25 time slots) as shown in Figure 2A. Moreover, the use of embodiments of the present invention can increase the peak transmission rate in a multi-carrier system by a factor of four because four carriers are used in parallel in this example using a single-carrier phase in the transmission structure of Figure 2A. The implementation of multi-carrier transmission of the radio block is transparent to the upper layer as long as the embodiment of the present invention does not affect SNDC (sub-network dependent aggregation protocol), LLC (logical link control) and RLC (radio link control) transmission. Parameters (for example, windows, etc.). However, MAC (Media Access Control) can be affected by embodiments that use multi-carrier transmission, and the time slot and timing structure of the GSM radio interface need not be modified. Thus, a multi-carrier redundancy improvement embodiment may be easier to introduce than a simple multi-carrier option in which four rLC/mac streams are transmitted in parallel on four parallel carriers, each of these streams The device is still transmitting in GSM according to the GPRS protocol (eg GPRS R99). Each GPRS R99 uses four parallel rlc/mac streams to make the RLC protocol more complex, since these four streams can cause unpredictable behavior of the window size and sequence number space on the receiver side. An incremental redundancy scheme according to at least some embodiments can be constructed by transmitting different redundancy versions of the same information block. By combining different versions, the receiver can improve the possibility of error recovery for proper reception. Various redundant versions can differ in modulation, coding or pUncturing schemes. However, the redundancy version and the initial transmission are usually selected from the coding scheme of the same family, 105485.doc -20· 1375426 or the initial version. By way of illustration, the MCS coding scheme is classified by family (e.g., Group A (MCS.3, MCS #MCS_9); 2 and MCS-7); and Group C (MCS_1AMCS_4)). The initial version and the redundancy version should belong to the same MCS"family". For example, if the initial transmission is encoded as MCS_7 (the _ zebra scheme), the redundancy version also belongs to the B family, for example, MCS-2 or MCS-5. Fig. Zhongtian-Multicarrier system constructed at least in accordance with a redundancy scheme of some embodiments of the present invention. As shown, the multi-carrier architecture allows different technologies to be used for different redundancy versions on each carrier. This allows for the simultaneous transmission of individual redundancy versions using different carriers (e. g. 'different frequencies). Or, in some embodiments, at almost the same time (but not necessarily at the same time, each of the several versions 1 may be sent within the (4) transmission time limit ((4): after the start of the transmission until the beginning of the next initial version: Each redundancy version. In some implementations, for example, in the bribe system, the transmission time limit can be equal to the duration of the frame. 7 blocks are two or three different redundancy versions.

The attenuation on the wireless link tends to have a frequency selection f...so different transmissions transmitted on different carriers may experience different amounts of attenuation. The embodiment in which multiple redundant versions are simultaneously transmitted on different carriers can be used in Figure 4. Frequency diversity is provided in the carrier system, rather than the conventional system of Figure (9) providing only time diversity. In some cases, it is more likely that an error occurs within a certain frequency due to fading. According to an alternative embodiment of the invention, the initial version is transmitted on a frequency known to be degraded, and the redundancy version transmitted on the non-deprecated frequency can be encoded the same as the initial version of the coding T case ( For example, the initial version of 'susceptibility to attenuation=mcs_6, rather than the number of versions of the salty version = MCS_6. This embodiment uses a common rule of thumb for encoding redundant versions using different coding schemes in the same family; The encodings of the different versions are the same, so this embodiment is considered to be only k for redundancy rather than incremental redundancy. "Can: Any dry embodiment suitable for the specific needs of the operator or even suitable for a particular situation to construct according to the present invention Carrier incremental redundancy scheme. Various embodiments using a self-decoding redundancy version can be implemented using either a selective combination, a soft combination, or a selective soft combination. The combination is selected such that the interface U is selected only by use. A redundant version of the program is used. Soft combining is a program that combines all transmission/reception redundancy versions using statistical algorithms or other methods for private rent recovery procedures. The selective soft combination is a program in which more than a few versions are broken and other redundant versions are discarded. The redundancy version can be selected according to the predetermined decision rule. One of the rules is The first redundancy version is selected for combination (if an error is initially made) and then an error check is performed on the transmission I > 9. For example, the error carrier may be at 105485.doc -22- 1375426. Sending the first redundancy version (ie, the first version to be decoded) 'where the wrong carrier is the primary carrier of the multi-carrier structure. If still the error is detected, the first two redundancy versions are combined with the initial version. And complete the other round of error checking. As long as you continue to _ to the error, the dragon needs (and depending on whether it is available) to add more redundancy versions. The receiver can be configured to construct - or multiple selection combinations, soft combinations or selections The logic of the soft combination depends on the conditions and parameters affecting transmission/reception; for example, carrier-to-interference ratio f-line-electricity, noise conditions, atmospheric or other interference conditions, interference σ, allowable transmission power or landscape邙舍', ringing The signal is received (or another terminal and other similar conditions and parameters. The decision can be based on the measured C / I or shadow plastic - or other parameters of multiple carriers. Make the choice of combination ^ = τ The decision can only be made by the algorithm in the receiver, the quantity: write::. or 'can control the decision at the transmitter and pass it to D' or can be at any intermediate point (such as PSTN) BTS' SGSN/MSC, or two final control of the entire communication link. J town ^, daytime point) Figure 5 depicts the implementation of variable time-frequency expansion with less - implementation incremental redundancy. According to the conventional method of the present invention, the implementation of the actual 丨φ, as long as the selection of different MCS coding schemes with the wrong value of the same information block; 3 ' attributed to the real-time value of the new transmission of the wrong room Different from the initial transmission. For example, the sum of the transmissions (the duration of the transmission time of the first transmission 211 of the MCS is shorter than ^2B) is the sum of the transmissions and the coding schemes. f The new transmission wheel contains the news. Embodiments of the present invention can overcome this disadvantage by 105485.doc •23-I3?5426. Therefore, after the first transmission is performed with an MCS, the line electrical block 5〇i, the retransmission with the two MCS-3 radio blocks can be performed for a duration not longer than the first transmission. As shown in FIG. 5, by using two independent carriers (carrier n+2 and carrier η+υ, respectively, retransmission via two MCS.3s (first retransmission portion 5〇3 and first-retransmission portion 505) Sending a redundancy version, embodiments of the present invention can exploit a multi-carrier architecture. Embodiments of the present invention do not take longer durations to perform the actual transmission of the redundancy version, but instead use multiple carriers to parallel ==, CS to The mapping of the number of carriers/locations can be predetermined or determined by sub-differentiation, or can be specified in a checklist. It is apparent from Figure 5 that 'two retransmission blocks 5〇3 and 5〇5 and receive. For the terminal In the embodiment where the carrier is known to transmit on one carrier or more than two cores, the mobile terminal preferably continuously and lightly controls the parallel carrier. For example, the line terminal machine monitors the initial load = 2 The two or two carriers that are retransmitted are transmitted thereon. The line (four) end machines continuously monitor and (four) waves such that embodiments of the present invention can avoid out-of-band control channels (eg, HSDpA^xEv move=required' when it occurs Transmission and retransmission However, in the version of the subcarrier mapping.

A t* carrier, multiple redundancy embodiment that provides redundancy for error recovery purposes. In the example shown, the initial version (6) containing the M message is transmitted in parallel with the other two (10)·3 transmissions 603 105485.doc • 24· 1375426 and 605 containing the same information, with transmissions 603 and 605 being used as initials. Redundancy version of version 601. Other coding schemes other than MCs_3 and MCS-6 can be used as known to those skilled in the art. The embodiments depicted in the figures can be used to provide incremental redundancy for EDGE or other similar wireless services or systems. These embodiments are configured to exploit a multi-carrier architecture by transmitting different redundant versions simultaneously and in parallel on different carriers. In the EDGE system, backtracking compatibility is achieved by maintaining the same RLC/MAC architecture as used in GSM, meaning that blocks belonging to the same "family" are transmitted in parallel. In this embodiment, Different numbers of carriers in a carrier radio system transmit individual redundancy versions. For example, as discussed above, one MCS_9 radio block, two MCS-6 radio blocks, and four Mcs_3 radio blocks can be transmitted with different redundancy. The same amount of information in the version form—thereby using one, two, and four parallel carriers eMcs_9, MCS_6& MCS_3 from the same red system and having a 1-2-4 encoding rate relationship. Alternatively, the redundancy version can be derived from different MCS. Family code 'as long as bit stuffing is used to compensate for different block sizes of individual mcs families. The receiver according to an embodiment of the invention may perform either a combination of choices, a soft combination or a combination of hard and soft combinations. For example, by river (:3_6 and ?4(:!§_3) The same information is required to transmit three parallel radio blocks on three carriers: one carrier for MCS_6 and two for two Mcs_3 wireless Electrical block. Here, 'because the coding rate is halved, twice the MU" radio block is required. As long as the receiver receives a subset of the transmission blocks (for example, if the three blocks of the transmitted round are received) Any of the two) can exploit such a multi-carrier architecture. 105485.doc • 25· 1375426 Embodiments of the present invention can reduce latency, enhance peak rates, and improve coverage. Since the receiver can be implemented in multiple The area is transmitted in parallel on the carrier. Therefore, the same performance can be achieved with lower C/I because the instantaneous coding rate is smaller. Generally, in order to fully utilize the performance of EDGE, a high c/i value is required. A method of setting initial parameters to practice at least one embodiment of the present invention is depicted. The method begins at 7〇1 and enters 7〇3 to select a modulation and coding scheme for the initial version and the redundancy version of the information. The message to be transmitted using the EDGE radio interface can be encoded using (4) κ modulation and can be encoded by Xia-6 coding scheme. In this example, the corresponding redundancy version can be encoded by McS_3 using GMSK modulation. It is not limited to these examples, but a coding scheme known to those skilled in the art can be used, and σ, in addition, there is no need to select a modulation and coding scheme each time a message is transmitted. Preset the modulation and coding scheme, or use the predetermined modulation and coding scheme for a specific group. For the selection of the coding scheme (as a preset scheme or for a specific communication), it is better to make the coding scheme suitable. Conditions at the time. For example, if the receiving conditions are excellent, then:: remainder / (that is, the redundancy scheme occupying the minimum resource can be determined as 5 palatable ^ on the one hand, if the receiving condition is bad and the error rate is relative The comparison::= can choose a more robust redundancy scheme, which may use relatively more resources as a compromise to provide better error resilience. For example, - an incremental redundancy plan that provides a very robust result is to encode the initial version of the information as an MCS-9 transmission, and to make the first and the second redundancy by the two MCS·6 transmission group versions by four (10) · 3 transmission components. In addition to the initial message (initial version 105485.doc -26· 1375426), two independent redundancy versions encoded in different formats provide excellent error recovery. Once the coding scheme is selected in block 703, the method proceeds to 7〇5, where the transmission strategy is determined. The term "transmission strategy" as used herein includes the relative timing for transmitting individual transmissions/retransmissions. For example, an initial version of the information (e.g., 501 of Figure 5) may be sent first, and then one or more versions (e.g., '5G3 and 5〇5 of Figure 5) may be simultaneously transmitted. In at least the embodiment, the second redundancy version is transmitted. This can be done while the first redundancy version is being transmitted (e. g., the same time period as 503 and 505), or can be subsequently executed. Alternatively, all versions (for example, the initial version and all redundancy versions) can be sent at the same time (for example, Circle 4 or Figure 6). In at least one embodiment of the invention, the transmission policy can be predetermined such that the receiver knows when and where to monitor the second carrier, or simultaneously monitors two or two on-off to receive the redundancy version. The predetermined transmission strategy avoids the need for out-of-band signal transmission as required in conventional systems. • The coding scheme selection in $block 7〇3 and the transmission strategy in block 705 are predetermined to affect each other and may be performed sequentially or in any order. For example, the transmission strategy (Μ5) can be selected before the coding scheme (7〇3) is selected. These behaviors can be performed during the initial (10) P-UP) phase or preparation period and can be set as a preset condition. The selection of the coding scheme and transmission strategy can then be changed as needed. It is more suitable for current conditions, such as reception conditions, communication traffic formats and private income considerations, and various other similar types of conditions, such as timing depending on various types of content and Quality considerations. For example, voice transmission requires immediate error recovery (or minimal error recovery delay), while content transmission 105485.doc • 27-1375426 can be used with small delays, such as Internet browsing or email applications. Once the coding scheme and transmission strategy are selected, the method proceeds to 707 to select any other communication protocol known to those skilled in the art. Such agreements may include parameters for provisioning various network devices (e.g., Figure 1A2 Sgsn BSC/BTS 104 and/or mobile unit 12A), or parameters required to establish or tear down a communication link. Once the communication protocol is selected in block 7-7, the method proceeds to 709' where the method ends. The parameters selected in 7〇ι to 707 can be stored in 7〇9 for future use and transmitted to those parts of the system that require these parameters. The parameters can be stored in the memory 108 of the sgsn shown in Figure 1A or stored elsewhere in the system. Figure 8 depicts a method for practicing at least an embodiment of the present invention to provide error recovery for a wireless communication system. In block 8.1, the initial parameters are set as described in connection with FIG. Once the initial parameters are set, the method proceeds to 803' where it is determined if there is information to be transmitted. If there is no information to be transmitted, the method proceeds to block 8〇5 from 8〇3 to wait for the message according to the "no" branch and then returns to 803 to determine whether there is a message to be transmitted. In block 803, If it is determined that there is information to be transmitted, the method encodes the information to be transmitted according to the "yes" branch from 803. In this embodiment, even if the information to be transmitted has been determined and the method has entered Block 8〇7 or later steps to process the information, and the system continues to monitor the additional messages to be transmitted according to block 805. That is, the system can continue at block 8〇5: monitoring the new message to be transmitted while simultaneously A number of steps are taken to process the message to be transmitted. In block 807, as shown in Figure 7, * _ -_, as in Figure 7, the message is encoded according to the protocol previously defined in the initial phase. 105485.doc -28· 1375426 In an exemplary embodiment, an initial version of the message may be encoded using an MCS-9 transmission. Once the initial version of the message has been encoded, the method proceeds to 809 to encode one or more redundant versions. Assuming an exemplary embodiment uses one MCS-9 block for the initial version of the information, the first redundancy version may consist of two MCS-6 transmissions and the second redundancy version may consist of four MCS-3 transmissions. Note that most of the embodiments described herein relate to the act of processing a redundancy version (block __815), which is in response to the initial version of the obtained φ 及 and encoding, rather than responding to receiving any kind of transmission redundancy. The out-of-band signal of the remaining version. When the system encodes one or more redundancy versions for transmission based on the information to be transmitted in block 8.3, the redundancy version can be regarded as responding to the initial version. This is transmitted, for example, from Figure 4, where all versions are sent simultaneously. In which the redundancy version is not sent simultaneously with the initial version but within the same transmission time limit | that is, after the initial version transmission begins until In the embodiment of the time when the next initial version begins, the redundancy version is transmitted in response to the transmission of the initial version. In some embodiments (eg, some embodiments in the GSM system) The transmission time limit will be equal to the duration of the frame. If the redundancy version has been encoded, then the method proceeds to block 8 11. In block 8 丨, depending on the communication scheme used or the protocol or specification of the system. The carrier is selected. Once the carrier for the initial version and the one or more If redundancy versions is selected, the method proceeds to 813 where the versions are transmitted simultaneously or in some parental error manner 'e.g., according to the example discussed in connection with FIG. Embodiments. As described above, the transmission of the redundancy version may be performed in response to the initial version of the positive transmission, rather than in response to receiving any kind of 105485.doc •29-1375426 data failure information or sending a redundancy version. The out-of-band signal of the instruction. The initial version and the (these) redundancy versions are typically transmitted from a fixed base station (e.g., BSC/BTS HH of Figure 1A) to a mobile unit (e.g., 12()). Thus the square X-813 usually occurs in fixed __ coffee, and the block is called the block of Figure 9. Usually occurs in the mobile unit. In some embodiments, the mobile unit can transmit - the initial version and - or multiple redundancy The remaining version. The message transmission occurring in block 813 can be a single-transport (e.g., SMS message) or can be a large number of transmissions (e.g., voice bits transmitted as part of an ongoing call). Each initial transmission and associated redundancy version, block (1) may be transmitted after block 815, the heart of which decodes each transmission, and if the error is detected, the transmissions are combined. Various embodiments may use selective combination, soft combination And/or any of the selective soft combinations, which take the 2 construction scheme and the current reception conditions. The transmission is decoded and the group interface generates a combined version of the received transmission, then the method enters the block: 17 In an alternate embodiment, block m (four) rows-times (or not at all in some embodiments or in a particular case does not perform block 817 before the communication link is broken, but the method is directly from Block 815 enters 8〇5. Further in 817, 'determines whether there is a condition for guaranteeing a redundancy scheme or a change or a condition thereof. For example, if the existing redundancy scheme requires only one redundancy version 2, the error rate is still unacceptable. At a high level, the conditions may ensure that another instance of two or more redundant redundancy schemes associated with the initial version may be presented as a change redundancy (combination ancient, primary For example, if the existing redundancy scheme uses the selection group ^ but the error rate is higher than the predetermined threshold, the scheme can be changed to soft group 1 〇 5485.d〇c 1375426 'but error If the rate is above a predetermined threshold, the scheme can be changed to a soft group σ or a selective soft combination to attempt to provide better error recovery when the radio interface condition prevents error recovery at that time. Block 817 can involve changing ^ to avoid Due to attenuation and/or transmission errors due to attenuation, it may be related to a particular frequency in a particular set of conditions. Since different transmissions transmitted on different carriers may be attenuated by different amounts of attenuation, the variation in carrier frequency The error recovery results may be improved. In addition, block 817 may include any changes resulting from the new version of the software, downloaded patches, updates, to incorporate modifications to the telecommunications specifications or other similar types of periodic maintenance into the system. Once 817 is completed and any changes or updates to the redundancy scheme have been constructed, the method then returns to 805 to await the next message to be transmitted. Figure 9 depicts a redundancy version for decoding and combining in accordance with at least one embodiment. A block diagram of the method. Typically, such behavior occurs in a mobile unit or other receiver in which embodiments of the present invention are constructed. The blocks depicted in Figure 9 provide information regarding blocks 815 that may occur in the previous figure. Some details of decoding, combining, and error recovery. The method begins at block 9 (where, an error check is performed to determine if the initial version of the transmitted information contains an error. Error checking can involve any kind of common program or algorithm that is specified by the system, by the system operator, or by the action unit itself. For example, error detection may involve redundancy checks such as sum check codes, cyclic redundancy check (CRC), frame check sequence (FCS), or error correction code (ECC) (eg, Hamming codes, Ryder) - Reed_s〇1〇m〇n code, Ree£}-Muller code, Binary Golay code' convolutional code (conv〇iutj〇 Nai.c0(je), Turbo Shima 105485.doc -31 - 1375426. This or other similar programs known to those skilled in the art can be used for error recovery schemes. Different types of actions to determine if there are errors, such as performing channel measurements or received power measurements, positive or negative ACKs (answers), implicit estimates of mobile unit reception quality = or known to those skilled in the art. Any basin that receives an error is similar to the stroke or test. Or, if the reception condition is known to be below the level, it can be assumed that the received transmission contains an error, thereby utilizing the redundancy transmitted according to the embodiment of the present invention. The remaining versions until the known receiving conditions have been improved At the moment, if the error reading is completed in block 901, the method then proceeds to decision block 903. If no error is detected during transmission, the method proceeds to block 9 〇 5 according to the ''No" branch from block 903. Waiting for another transmission and then returning to block 901. In some embodiments, a preset condition may be specified in which one or more redundancy versions are combined with the initial version (" is "branch) regardless of whether (d) to the error. In the case of an error, the method proceeds to "is" branches from block 903 to block 907 to determine if the selection combination is to be executed. • 预定 the error recovery method is predetermined as a preset selection combination, selection a soft combination, a soft combination, or a combination of such error recovery common programs. Alternatively, the type of error recovery may be changed or may be selected to best suit the conditions, depending on the condition of the termination, the condition of the transaction at the time, and the economy. Or other similar parameters used to select the type of error recovery. In any case, if the selection cascading will be used at block 9〇7, then the method is based on, yes,, branching into the person Block 909, wherein a redundant version of the message is selected for error recovery. If it is determined at block 9〇7 that the selection combination is not used for error recovery, then the method enters 9 ι from 9〇7, and determines whether it will be used in 911. Selective soft combination. If it is 105485.doc •32· 1375426 at block 9 ι, determine if selective soft combination will be used in 911. If it is confirmed at block 9 ι, the selective soft combination will be used for error recovery, then the method The "• is" branch enters 913 from 911 to select and softly combine one or more redundancy versions to perform selective soft combination error recovery. If the selective soft combination will not be used, then the method proceeds to block 9丨5 according to the "No" branch. If it is determined that the selection combination (907) and the selective soft combination (911) will not be used, The available redundancy versions can then be soft combined for error recovery according to block 915.

Selecting an error recovery technique (eg, selection combination, selective soft combination, soft combination, or other similar error recovery technique), the method proceeds to block 917 and to the selected redundancy version or selected redundancy version. The soft combination is decoded. Once the aforementioned program ends, the method proceeds to 919 to execute the error recovery common program. Block 919 may require a behavior similar to that performed in the initial version error check in block 9〇 (or block 815 in the previous figure). In some embodiments, if the error recovery of block 919 fails, the method returns 901 to process the data in a further step. This is depicted as a dashed line between 99 and tear. For example, in the first round, the selection combination may have been selected (or preset) according to block 907. In the second round, the second redundancy version may be combined with the initial version and the first redundancy version in block 9〇7, or the soft combination (915) or selective combination may be selected in the second or rear wheel.
