[Prior Art] Only the forward link (FL0) is a digital wireless technology that has been developed by the wireless provider's industry-leading group (indUStry-led group). The FL(R) technology was designed for use in a mobile multimedia environment, and the FL(R) technology demonstrated performance characteristics suitable for use on cellular handsets. It uses advances in coding and interleaving μ to achieve high quality reception of both instant content streaming and other data services. FLO technology delivers robust performance and high capacity without compromising power consumption. The technology also reduces the network cost of delivering multimedia content by significantly reducing the number of transmission thieves that need to be deployed. This multimedia multimedia based on FLO technology complements the wireless operator's cellular data and voice services to deliver content to the same cellular handsets in the world. The use of F L Ο no, (4) to broadcast mobile audio and video signals other than affair to mobile users. Use a long and high power transmitter 133688.doc 200922251 ^ to perform each transmission to ensure that - in the given (four) domain h - 'usually deploy 3 rhyme transmitter devices in most markets; ensure that FL 〇 signal reaches one A significant part of the group in a given market. During the process of the (4) data packet capture process, a number of decisions and calculations are made to determine the frequency offsets such as the individual wireless receiver farms.性质 The nature of the FL0 broadcast captured by the multimedia material, and the efficient handling of this information and associated add-on information is of the utmost importance. For example, when determining frequency offsets or other parameters, complex processing and decision-making are required, where the phase and associated angle decisions are used to facilitate FLQ transmission and reception of the data. Wireless communication systems such as FLO are designed to operate in a mobile environment where channel characteristics expected to have significant energy channel taps, path gains, and path delays vary significantly over a period of time. In an orthogonal frequency division multiplexing (〇FDM) system, the timing synchronization block in the receiving device maximizes the energy captured in the fast Fourier transform (FFT) window by appropriately selecting the 〇fdm symbol boundary. Respond to changes in channel distribution. When such timing corrections occur, it is important that the channel estimation algorithm takes into account the day-to-order correction when calculating the channel estimates to be used to demodulate a given OFDM symbol. In some implementations, the channel estimate is also used to determine timing adjustments to the symbol boundaries that need to be applied to future symbols, thus resulting in a subtle interaction between the introduced timing corrections and the timing weights that will be determined for future symbols. In addition, the channel estimation block typically processes pilot observations from multiple OFDM symbols to produce a channel estimate with a better sfl average and also resolves longer channel delay spread. When pilot observations from multiple OFDM symbols from 133688.doc 200922251 are processed together to produce a channel estimate, it is important to align potential OFDM symbols with respect to symbol timing.

The modulator 32 〇 can also be provided for transmission by the transmitter 322 The transmitted signal is multiplexed. The description provided above for the processing system and the readable medium with reference to Figure 2 applies analogously to the components of Figure 3. Figure 4 illustrates an exemplary FLO physical layer superframe 4 〇〇. The hyperframe 400 can include time division multiplexing (TDM) Frequency (for example, deduction pilot mtdm pilot 2), wide area identification channel (WIC), area identification channel (lic), additional item information symbol ((10)), four data frames (for example, framer to the message) Block 4), locating the pilot channel (ppc) and the signal transmission parameter channel (spc). The MN pilot can allow fast operation of (10). (10) The location of the data for each media service in the hyperframe can be described. The hyperframe structure is not limited to the structure illustrated in Figure 4, and the hyperframe can be composed of fewer or more elements than those illustrated in Figure 4. _M is a multi-carrier modulation form that can be utilized The bandwidth is divided into n frequency groups, which are called subcarriers. For example, each subcarrier 133688.doc -14· 200922251 is modulated by a quadrature amplitude modulation (QAM) symbol. In fl, transmission and reception may be based on the use of 4096 (4K) subcarriers, and QAM modulation symbols may be selected, for example, from a self-talking or 16_QAM symbology. Each hyperframe can include multiple OFDM symbols. By way of illustration, the hyperframe can include 2 〇 FDM symbols in the available bandwidth per MHz (e.g., including 1200 〇 FDM symbols for a bandwidth of 6 MHz). In each symbol, there may be multiple subcarriers (eg, 4 subcarriers). These subcarriers can be collectively grouped into interlaces.

As illustrated in Figure 5, an exemplary interleaving structure can include (e.g., interlace. In this example, the interleaved index ranges from 〇 to 7 (i.e., 1 〇, n, 12 ' 13, 14, 15, 16, 17 And 18). For example, each interlace may consist of 5 subcarriers evenly spaced over the nickname bandwidth. There are 7 subcarriers between the 钊 near 钊 carriers in each interlace, each of which One is different and wrong. In each QFDM symbol, '_interlace can be assigned to pilot interlace and can be used for channel estimation. Here, 500 can be modulated by known (pilot) modulation symbols. Subcarriers. The remaining 7 interlaced or side subcarriers are available: by means of: symbol modulation. Although Figure 5 illustrates - an exemplary interleaved structure / power month 'but the parental structure / function is not limited to this configuration, and its There may be other configurations of class i (eg 'with any number of interlaces'). Errors may be evenly distributed in frequency such that they can achieve full frequency diversity within the available frequencies. These interlaces can be assigned to The logical channel whose duration varies with the actual number of interlaces. This is provided by Ren V. Source-aggregated time-diversity flexibility. Lower data; frequency C privately less interleaved to improve time diversity, while higher data disk 133688.doc 200922251 channels can utilize more interleaving to minimize radio working time And reducing power consumption. Figure 6 is an exemplary table of time slot to parent error maps. The vertical axis indicates the time slot index. The horizontal axis indicates the symbol index. The values in the table indicate the interleaved index. According to one aspect of the present invention, The slot may involve a group of symbols, an interlace may involve a group of subcarriers, and each slot may be mapped to a per-symbol period based on a slot-to-interlace mapping scheme. Corresponding to one of a set of periods or a group of modulated symbols. In another aspect of the invention, a time slot can be mapped to one or more interlaces, and the parent error can be mapped to one or more The time unit of the slot may include the mac time unit at the MAC (knife) layer and the OFDM symbol period at the entity (ρ Η γ) layer. The symbol period may relate to the MAC in the environment of the physical layer channel (pLc) allocation. Time unit, or OFDM symbol period in the context of subcarrier allocation. The symbol period may relate to the time unit of the symbol index. Although as previously described, the number of subcarriers (ie, FFT size) may be 4K 'but the technique does not Limited to this number of subcarriers or fft size. The present technology is capable of multiplexing and transmitting multiple data streams in various FFT-sized OFDM systems. For an OFDM system with a 4K FFT size, 500 time slots can be formed. One group of modulation symbols is mapped to an interlace. In one aspect of the invention, the time slot can be fixed on different FFT sizes. Furthermore, the size of the interlace can be 1/8 of the number of active subcarriers, and The time slot can be mapped to one or more (including one) interlaces based on the FFT size. The interlaces assigned to the one-time slot may reside in multiple OFDM symbol periods. For example, for a 2K FFT size, a one-time slot (i.e., a 5 〇〇 modulation 133688.doc -16 - 200922251 symbol) maps to two interlaces on two consecutive 2K OFDM symbols. Similarly, for the IK FFT size, the one-time slot is mapped to four consecutive ικ (the four m 上 on the ^ 〇 river symbol, as an example, since the subcarriers that can be used may not include, for example, protection subcarriers, The number of subcarriers that can be used for 1K, 2K, gang, and 8 FFT sizes can be 1 〇〇〇, 2 〇〇〇, 4 〇〇〇, and 8 _> respectively. That is, for example, the mFFT size contains 1 024. Subcarriers, of which 24 of the subcarriers can be used as guard subcarriers. For example, the number of subcarriers can be increased in proportion to the FFT size. It follows that for 8K FFT size, the time slot maps to _ One-half of the half-bit interleaving on 8K OFDM symbols. Note that regardless of the fft size, a MAC time unit can contain, for example, 8 time slots. The following table shows the FFT sizes of 1K, 2K, 4Κ, and 8Κ and their respective An exemplary relationship between the number of FDM symbols per Mac time unit, the number of interlaced subcarriers, and the number of interlaces per time slot. FFT size number of OFDM symbols per MAC time unit per interleaved subcarrier Number of interlaces per number of slots Head

Table 1 The exemplary relationship between the OFDM symbol index and the MAC time index is shown in Table 2 below. 133688.doc 200922251 FFT size OFDM symbol index for MAC time index m (m = 4'5...) 1024( 1Κ) 4m - 12, 4m - 11, 4m - 10, 4m - 9 2048 (2K 2m _ 4, 2m 3 4096C4K) m 8192(8Κ) im+3V2 Table 2 According to one aspect of the present invention, the relationship between the M AC time unit and the OFDM symbol depends on the relationship between the slot and the interleave, The technology can perform MAC layer multiplexing on the MAC time unit and on the slot, regardless of the FFT size of the OFDM system. For various FFT sizes, the physical layer can be mapped to the OFE&gt;M symbol and interleaved separately in wMAC time units and slots. While the above examples refer only to IK, 2K, 4K, and 8K FFT sizes, the techniques are not limited to such specific FFT sizes, and other FFT sizes can be implemented without departing from the scope of the present technology. A system can include multiple time slots per symbol (e.g., as shown in Figure 6, 8 time slots per symbol). Other time slots (e.g., time slots i through 7) may be used to assign to the data symbols when a time slot (e.g., time slot) can be assigned to the pilot symbols. The pilot symbols are known a priori by the transmitter and receiver devices. By way of illustration, the pilot symbols can be used by the transmitter or receiver device for frame synchronization, frequency acquisition, and timing acquisition. In this example, the time slot can be referred to as a pilot time slot. And the s1 i slots 1 to 7 can be referred to as data slots. Alternatively, multiple time slots (e.g., stalks 1 and 3) can be assigned to the pilot symbols, and the remaining time slots can be assigned to the data. In this alternative example, time and 3 may be referred to as pilot time 梓, and the remaining time slots of &amp;&amp; | 0 may be referred to as data time slots. 133688.doc -18- 200922251 Although Figure 6 illustrates an exemplary time slot structure/function, it is limited to this configuration. The time slot structure, the function can have other class two structures. For example, the time slot structure can have any number of time slots, and the time slots can be allocated in many different forms and for various types of information. . Each of the 'time slots' is assigned or mapped to an interlace. Queue &amp; time slot 1 is assigned to consecutive 〇FDM symbol indices 4, 5, 6

6, 3, 1, etc. on 6, 7, 8, G, etc. , 7 ' 5, 4, etc. Interleaved interleaving, which may be involved in time slot mapping or to be mapped, may involve time slot interleaving associated with pilot time slots, in accordance with the present invention. In another aspect of the present invention, time slot interleaving may involve interleaving mapped or to be mapped: slots. Pilot interleaving may involve time slot interleaving associated with pilot interleaving. In yet another aspect of the invention, the time slot interleaving may involve a time slot to interlace mapping function or an interleaved to time slot mapping function. The time slot to interleave mapping function and the interleaved slot mapping function can be the same or equal, except that the time slot to interleave mapping function can utilize the time slot (or time slot index) as input and provide interleaving (or interleaved sci-fi as output and interleaved to time slot). The mapping function can utilize interleaving (or interleaved index) as input and provide time slots (or time slot indices) as output. For example, time slots, interleaving, pilot time slots, pilot interleaving, symbols, and similar terms have The time is used to refer to the time slot index, the interleaved index, the pilot time slot index, the pilot interleaved index, and the symbol index. 'such as 'live video and audio channels'). Think of a service as one or more audio, text, or service-related or multiple logical channels (called a multi-FLO system that can multicast various service streams (for example, news, music, or sports-related data components (such as video) , a combination of signal transmissions. Each FLO service can be carried on - 133688.doc -19- 200922251 Broadcasting Channel (MLC). For example, it can be in multiple MLCs (for example, two different MLCs) Send - the video and audio components of a given service. One or more time slots of the data symbol can be used for the MLC. For example, time slots 1-3 can be used for the video component of a given service, and Time slots 4-7 are used for the audio component of a given service. The following describes in detail an exemplary system and method for generalized slot-to-interlace mapping (for FLO). These systems and methods can support FL〇 transmitters. And the entire series of slot-to-interlace mappings in the receiver device. The generalized slot-to-interlace mapping provides different length channel estimates that can be computed at the receiver device and better Düsseller. Elasticity Slot-to-interlace mapping is sometimes referred to as flexible time-slot-to-interlace mapping. Sometimes it is possible to use the "corresponding frequency-frequency I difference pattern" in the time slot 1 interleaving (four) for a specific time slot-to-interlace mapping. For 4K mode The FLO null intermediary specification (TIA_i 〇99), along with its associated implementation, supports a staggered pattern called the (2,6) pattern. In this case, the pilot interleaved in the super-frame of continuous FDM The sign on the symbol alternates between 2 and 6. The (2,6) staggered pattern provides pilot observations from two distinct interlaces 2 and 6. This allows up to 1〇24 in 4K mode operation. Calculation of the length of the channel estimate. Although (4) 24-length channel estimates can be deployed in areas such as the United States, but in other FL〇 deployment modes (eg, Han mode or medical band deployment), "to support longer channel estimates" Two pilot interleaving lengths. Time slot to interlace pattern such as time-to-interlace pattern using (〇, 3, 6) and (0, 2, 4, 6) pilot staggered patterns can also be used to allow channels 133 133688.doc -20. 200922251 簠 activity. These types can be based on an example The scheme provides maximum 4096 and 2048 length channel estimates respectively. It is also possible to estimate longer channel delay spreads (eg, greater than 4096 and greater than 2〇48) with higher channel estimation errors. According to one aspect of the present invention, flexible Time slot-to-interlace mapping is used for ois and data symbols. TDM pilots (such as TDM pilots and ^2 pilot 2), WK:, LIC, PPC, and SPC symbols can have and are in the frame for the superframe. The rest of the time slot-to-interlace-independent fixed interleaving. Under normal operating conditions, the FL〇 receiver device can determine the slot-to-interlace to be used after decoding the symbol (which appears at the end of the hyperframe) Mapping. An exemplary implementation of a generalized slot-to-interlace mapping using (0, 3, 6), (〇, 2, 4, 6) and (2, 6) pilot staggered patterns is described in detail below. The time slot to interlace mapping and associated implementation are based on pilot interleaving and different data time slots: the concept of distance vectors. The length of the distance vector can be the number of interlaces minus the number of pilot interlaces. In these examples, 8 interleavings and 8 time slots are used. However, the present technology is not limited to such a number that any number of interlaces and any number of time slots can be utilized. (0, 3, 6) Staggered Pattern The pilot interleave vector (6) can be determined by the staggered pattern. For each-time slot to interlace mapping, one or more distance vectors (9) can be defined. Distance vector; used to determine the interlaced index of the slot when the body is in the body. After determining the pilot interleaving, I uses the remaining interleaved configuration time slot so that the relative distance of the resulting interlace for the -to-time slot can be obtained from (or) a distance from (a). One exemplary implementation of this is described below.

By way of explanation, for the (〇, 3, 6) staggered pattern, (iv) 〇 3 from HU 133688.doc -21 - 200922251 and assuming /^ again with ^... for (6) and the staggered ^ pilot jump is 3, and /« It is judged as follows: (1) starting from step (4) and starting with q, (8) adding pilot value 3 to 1 initial value to obtain 3 as the next value, (4) adding 3 to get 6, (iv) plus 3 to get 9 Translate to! , ("add 3 to get 12, which is translated to 4' (W) plus 3 to get 15, which is released to 7, (_ plus 3 to get 18, which is translated to 2, and (viii) Add 3 to get 21, which is translated to 5. The above translation can be performed using, for example, the total number of interlaces and modulo operations. Suppose "express the 0FDM symbol index in the superframe, its _" from 〇 to 1199' The symbol index 〇 corresponds to TDM1. It is assumed that s represents the time slot index, so that the interval from 0 to h is assumed to be the time slot interlace corresponding to the time slot mapping in the misplaced symbol index to be staggered. Note, small, The center can take values from 0 to 7. The day slot (ie, (iv)) corresponds to the interleaved pilot time slot given by the selected staggered pattern. Therefore, the time slot is staggered 7 [〇, It can be called pilot interleaving. The ', σ疋 OFDM symbol index can be determined by using the w index to eight to determine the pilot interleaving (/[〇川). For example, /[〇,中物m〇d8 )]: For: the bedding time slot 'first based on 〇1? and the symbol index' calculates the rotation factor &amp; for the distance ID. For example, = mod7 执行 then proceeds to s Z ) Right cyclic shift (right shift clamp). Assume that the vector after the right loop shift is . Then, the time slot-to-interlace mapping of the information time slot in the 〇FDM symbol index can be small,"] = (take + ή) _8, where = 1, 2, ..., 7 are given. The mapping is ensured that in every block of 7 consecutive 〇FDM symbols, each time slot is found at all possible distances from the pilot interlace. In addition, in the block of contiguous 133688.doc -22-200922251 OFDM symbols, each time slot occupies 7 times fine, and the parent can use interleaving. Each time slot experiences a window of 17 OFDM symbols φ from all available interleavings at least once. It is also guaranteed that there are at least three intermediate OFDM symbols in front of the slot when a particular handover is sent to the same slot. (2,6) Staggered Patterns The pilot-to-interlace mapping based on the (2,6) staggered pattern can be implemented using pilot interleaving and distance vectors. In this case, use a pilot interleave vector (7〇) and two different distance vectors (

』...0 and 仏) to achieve the entire time slot to the staggered pattern. By stating 'for (2,6) staggered patterns, /d=[2,6,2,6,2 6,2,6], and false =[6,2,4,7,3,1, 5] and D Yan [2,6,4,3,7,5,1]. Using the above notation, the time slot interleaving/one] (which is the interlace corresponding to the time slot y in the 〇FDM symbol index) can be determined as follows: 曰1· Given the OFDM symbol Yu Gong 丨, then borrow The n-index can be used to determine the pilot interleave (/[0, "]). For example, 2. If "is even, set D to I". ‘[〇,“]=/[(« m〇d8)]. . If Λ is odd, set £) to 3. For the data time slot 'first based on the ugly symbol index', calculate the rotation factor for the distance vector D. For example, ' Α = πηκΠ. The right cyclic shift (right shift heart position). Assume that the right-shifted vector is gas. Then, the time slot-to-interlace mapping of the data slot in the 〇FDM symbol index can be small, „]=(/ [M]+Z)fi w)m〇d8, where =1,2,...,7 are given. Note that in the case of two distance vectors, there is an index based on 〇FDM symbol 133688.doc 23- 200922251 "Additional steps to select the appropriate distance vector. In order to make the structure general: 'Eight different distance vectors can be used for any pilot interleave vector. In addition, the off-structure can also produce two interleaved pilot staggered patterns' The pilot interleave and distance vector can be appropriately selected in the software. (0, 2, 4, 6) The staggered pattern can be implemented based on ((), 2, 4, and the difference type using pilot interleaving and distance vector. Slot-to-interlace mapping in the case of sex-generalization. In this example, the pilot-interleaved vector (/〇) and a range are used. (9) Let's see the whole time slot to the staggered pattern. By using the above description for the 'de-(four) staggered pattern throat (10) from ten and the assumption 〇 = [1, 6, 4, 2, 7, 5, 3]. The number method, the time slot interleave squeak can be determined as follows: 1. Given the OFDM symbol index, the pilot interleave (/[0, «]) can be determined by using „index to 。. For example, /[ 〇, w=/[(wm〇d8)] 2. For the data time slot, first calculate the rotation factor /?„ for the distance vector Z based on the OFDM symbol index. For example, and, ~m〇d7. The right circular shift (right shift) of the distance vector Z) is then performed. Assuming that the vector after the right cyclic shift is Ζ)β, then the time slot-to-interlace mapping of the time slot of the OFDM symbol index π can be [_y])m〇d8, where=1, 2,..., 7 is given. For each of the exemplary implementations, each time slot (except for the pilot time slot) is assigned to each of every 10 consecutive OFDM symbols at least once. For the one-time slot', after only three OFDM symbols, an interlace is repeated. The distance vector of a given length 7 is in the block of 7 consecutive OFDM symbols, each time slot occupies 133688.doc •24- 200922251

According to all possible distances staggered from the pilot. In addition, in the block of 28 consecutive OFDM symbols, each time slot occupies the interlace, 2, 4, and 6 times and interlaces 1, 3, 5, and 7 four times. Referring back to Figure 6, this concept is explained in detail. For the above (0, 2, 4, 6) staggered pattern, each of time slots 1 through 7 is assigned to interlace 0, 1, 2, 3, 4, 5, 6 in every 10 consecutive OFDM symbols. And each of 7 at least once. For example, for OFDM symbol index 4, time slot 1 is assigned to interlace 3 'for OFDM symbol index 5, time slot 丨 is assigned to interlace 1, and for OFDM symbol index 6, time slot 丨 is assigned to interlace 〇, for 〇 FDm symbol index 7, assign time slot 1 to interlace 7, assign time slot 1 to interlace 5 for OFDM symbol index 8, and assign time slot 至 to interlace 4 for OFDM symbol index 9, for OFDM symbol index 丨Hey, time slot! Assigned to Interlace 2, for 〇FDM symbol index 1:1, time slot 1 is assigned to interlace}, for OFDM symbol index 12, time slot 丨 is assigned to interlace 7, and for 〇fdm symbol index 1 3, time slot 1 Assigned to Interlace 6. Still referring to Fig. 6, for a one-time slot, an interleaved index is repeated after only three symbols. For example, for time slot 交错, interlace 0 is repeated only after 3 consecutive 〇FDM symbol indices. This is the same for interlace 2, interlace 4, and interlace 6. In addition, Figure 6 illustrates that each time slot occupies all possible distances from the pilot father error in seven consecutive 〇 FDM symbols. For example, time slot 〇 is used for pilot interleaving, and for OFDM symbol indexes 4, 5, 6, 7, 8, 9, and 10, respectively, to interlace 2、, 2, 4, 6, 〇, 2 And 4. For OFDM symbol indices 5 6, 7, 8, 9 and 10, time slots 3 are assigned to interlaces 6, 5, 3, 2' 1, 7, and 6, respectively. Therefore, the distance between the time slot 3 and the time slot 为 is the absolute value of the difference between the time slot 3 133688.doc -25- 200922251 and the interleaved index of the time slot 。. In this example, for the OFDM symbol indices 4, 5, 6, 7, 8, 9, and 1〇, the distance is 6, 3" for the translation of -!), 4 (which is the translation for .4), (4). For example, by performing a modulo operation, an absolute value can be obtained. In accordance with the present invention, one or more pilot interlace vectors ^ 1 〇 /;, B, etc. may be utilized, and - or a plurality of distance vectors (eg, Α, etc.) may be utilized. The number of time slots and the number of interlaces are not limited to 8, and each of them may be any number. Therefore, a number of time slots and sample interleaving can be stored. Variable body and "can be the same. The length of each of the pilot interlace vectors can be an exemplary implementation that can be described as follows: f 1. Given an OFDM symbol index, can be selected from the one or more pilot interlace vectors based on, for example, - The pilots are interleaved to ^. A pilot interleaving can be determined by directing the moving cable to the selected /. For example, /[0,"]=/[(« mod ml)], where Wl is any integer. It may also be possible to have more than one pilot interlace. For example, the pilot interleaving can be expressed as follows: /bc, "] = / [( „ mod wl)], where X can represent the index of the pilot time slot. The index of the pilot time slot does not require phase _. In this case, the pilot time slot can occupy the time slot, the time slot 3 and the time slot 7, in which case X = 1, 3, 7. 2. Given OFDM symbol index, then based on eg "based on" m 〇d 2, where W2 is any integer) and/or optionally the pilot interleaving selected in step 1 above, selecting a distance vector Z from one or more distance vectors. 3. For the data slot, first Based on the 0FDM symbol index, the rotation factor l for the vector D is calculated for distance 133688.doc •26- 200922251. For example, ancient,

0 Han n — k n rnr\H m3, where each of moxibustion and w3 is _ number. The receiver performs the right cyclic shift of the distance vector D (the right shifting bit recognizes the adan * η sighs right after the shifted position "". Then, the 0FDM symbol index species time slot to the interleaving The mapping can be *. partial, which; m1, p gives, μ is any-integer. If there are multiple pilot parent errors (such as /[X,♦ then the time slot to the interlace mapping table is small '"] = (small, "] + £ ^ [s]) modw4, 苴中可砉 _

/, the table is not the index of the pilot time slot (for example, 'data time slot'). Variant moxibustion, "d and can be the same or different. There may be more than one twiddle factor. According to one aspect of the invention, one or more of the following characteristics (or all) can be combined with the generalized time slot to Interlaced mapping is associated: 1. An interlace is associated with a non-adjacent subcarrier (e.g., 10 is associated with a non-adjacent subcarrier index 48, 56, etc., as shown in Figure 5). One is a different interleave of the 虞-group continuous symbol. For example, in Figure 6, time slot 2 occupies the interlace 1, 7, 6 on the continuous symbol index 4 5 6 , 7 and 8. 4, 3. Thus, every 4 slots can occupy every available interlace on a set of consecutive symbols, and the time slot to interlace assignment can change over time. 每一. Each time slot occupies a distance from a set of consecutive symbols All possible distances of pilot interleaving. The number of consecutive symbols in the group can be the number of interlaces minus the number of pilot interlaces. For example, in Figure 6, at symbol indices 4, 5, 6, 7, 8 On the 9th and 10th, the distance between the time slot 6 (data slot) and the time slot 导 (pilot time slot) is 7, 4, 1, 5, 2 , 6 and 3. I33688.doc •27- 200922251 Because, the main 'time slot 6 occupies all possible distances (1 to 7) from the pilot interleaving from six consecutive symbols. Only after a predetermined number of consecutive symbols will Each time slot is assigned to the same intersection 9 In other words, for a given slot, an interleaved index is repeated only after a predetermined number of consecutive symbols. For example, in Figure 6, the time slot is again after only two consecutive symbols. Assigned to interleaved. Hardware Implementation Architecture Figure 7 is a conceptual block diagram illustrating an exemplary hardware implementation for generalized slot-to-interlace mapping. A transmitter or receiver device processing system 710 can include a The frequency interleaving vector unit 71 〇, a distance vector unit 73 〇 and the slot father error calculation unit 704. In this exemplary implementation, § time slots and 8 interlaces are used, but the technology is not limited to such numbers. Time slots and interleaving. 各种 Various parameters (such as pilot interleave vectors, distance vectors, and other control parameters such as shift-enable) to be used to calculate time slot-to-interlace can be programmed by software to allow In use Easy programmability in mapping. The software may be able to directly program hardware temporary storage containing some of these parameters (eg 'pilot interleave vector unit 71 〇 and distance vector unit 73 0). (Based on preset parameters) or stylize these parameters after processing the spc symbol. In addition, 'when the software tries to program these registers, the hard system wakes up. Because the hardware sleep timeline can be used in the software, the software Sleep-related issues can be easily handled. Direct control is provided to the software to ensure that OIS decoding is enabled in the software when appropriate. OIS decoding can be enabled after the time slot to interleave parameters are programmed into the hardware. Doc -28- 200922251 The pilot interlace vector unit 710 can include a pilot interlaced vector heart including, for example, an 8x1 vector that is stylized by software. Each element of the vector can be 3 bits long (to represent one of the eight interlaces from 000 to 111). For a staggered pattern such as (2, 6), the pattern can be repeated periodically until all eight elements in the vector are exhausted. For example, the (2,6) staggered pattern produces one (2,6,2,6,2,6,2,6) pilot error vector/0. The (〇, 3, 6) staggered pattern produces a pilot interleave vector /0 of (〇,3,6,1,4,7,2,5). The (〇, 2, 4, 6) staggered pattern produces one (0, 2, 4, 6, 0, 2, 4, 6) pilot interleave vector / 〇.

The software can also be programmed with a distance vector unit 73, which includes, for example, an 8χ7 distance vector table. Three bits can be used to represent each item in this table. As a result, the table can include 8 columns, each column having a length of 21 bits. Each column in this table corresponds to a distance vector. As in the case of pilot interleaved vectors, if the number of distance vectors is less than 8, the distance vector is periodically repeated to fill the entire table. Therefore, in the case of the (0, 3, 6) pattern, a vector is repeated 8 times to fill the table. In the case of a (2,6) staggered pattern (where there are two distinct distance vectors), the 'per-distance vector appears four times in alternating positions in the table. The software can handle periodic iterations when writing to the table. The shift enable flag 775 (1 bit) can be used by the hardware to generate an offset or de-energy distance vector based on the OFDM symbol index (#% rotation. This shift enable flag 775 can also be initialized by the software. The pilot interleave vector and the distance vector are initialized by two. The hardware operation is performed. Corresponding to the time slot to the interlace mapping in the super frame, after all the software is programmed, the OFDM symbol in the following description can be used. Index OFDM symbol index. The hardware first uses the pending 133688.doc -29-200922251 OFDM symbol index, selects the three least significant bits (1^8) (modulo 8 operation) and uses three LSB indices to the pilot interleave vector. To obtain pilot interleave Q, in order to save the scratchpad space, the pilot interleave vector can be stored in the 32-bit scratchpad vector using 8X3 = 24 bits. The format can make the 〇Fdm symbol index 导 pilot Interleaving occupies the least significant 3 bits. The pilot interlace can occupy three bits of position (n mod 8) * 3, (n mod 8) * 3 + 1 and (n mod 8) * 3 + 2 from the inward Given. Suppose this is represented by gossip, .... ◦ FDM symbol index π The index can be indexed to the distance vector and the rotation factor used on the distance orientation. The shift enable flag 775 set by the software (depending on the time slot to the interlace mapping being used) can determine whether the non-zero rotation is to be used. On the distance vector. If the shift enable flag 775 is set, the left shift unit 795 is first used to shift the 0FDM symbol index to the left by 1 (by 2), and then the modulo 7 unit 790 is used to perform the simulation on the result. 7. The multiplier 770 multiplies the result by 3 (to consider the 3 bits used by each of the distance vector tables) to reach 'the argument used as the right cyclic shift unit 742. OFDM symbol index w It can also be used to select an appropriate distance vector column in the distance vector matrix. For example, three LSBs of a 〇FDM symbol index (eg, "m〇d 8) can be used as a column index to select a distance vector to produce. The distance vector Z) is then cyclically shifted to the right (the number of shifted elements is equal to the argument given by &amp;). In this particular example, since the vector occupies the 32-bit 7C register Only 24 bits, so the cyclic shift operation needs to be Or, in order to simplify the hardware operation, the software can perform cyclic expansion of 24 bit vectors to 32 bits by placing 8 LSBs at the front. This extended vector can help cyclic shift of hardware. In this case, 133688.doc -30- 200922251 corresponds to 24 LSBs of the cyclic shift vector. The OFDM symbol index "data slot" to 7 slot error 725 can be obtained as follows. The previously obtained pilots are interleaved using adder ye and added to the two LSBs of 乂. Next, the modulo 8 operation can be performed on the result using the modulo 8 unit 75 。. The results can be placed into a data interleaving table unit 760, which can include a 1x7 vector. Each element in the vector can be 3 bits long. The first result may be that the time slots corresponding to the time slot 1 are staggered. In general, for time slot s, the interleaved index is given by the operation 3:3 Bu Wniod8. Note that in q, (x:y) corresponds to the bit position parent, xd.....y in the above expression. The interleaved indices obtained for all seven data time slots and pilot time slots can be stored in a lookup table (not shown) that can be indexed using the time slot index. When an OFDM symbol is received, the processing system 71 shown in Figure 7 can also be used to map an interlace to a time slot. The pilot interleave 72 〇 can provide a pilot of a given pilot father error, and the time slot interlace 725 can provide a given interleaving time slot. Processing system 710 can be pre-programmed with one or more pilot interleaving vectors, one or more distance vectors, and (as appropriate) - or multiple rotation factors. Alternatively, processing system 710 may receive some or all of such elements via other suitable components (e.g., a help network, other types of networks, other types of communications). For a given symbol index and interleaving, processing system 710 can provide a corresponding time slot n H given symbol index and pilot interleave using a time slot interleaving calculation unit, and processing system 710 can provide a corresponding frequency slot using a time slot interleaving computing unit. . Day (4) The real side of the interleaved unit: It may be similar to or different from the implementation of the time slot interleaving unit 740. ^ The modulo 7 implementation in hardware I33688.doc 31 200922251 The following detailed explanation can be used in the implementation of the time slot to interleave mapping - exemplary modulo 7 operation. For example, a mod 7 operation can be performed in which "the OFDM symbol is indexed in the frame. According to an exemplary configuration, only the adder is used to perform the modulo 7 operation. The basic concept is described below.

8 ξ 1 (m〇d7) is known. Therefore, any power of 8 is also equal to the model 7. Change + for any integer W, S^Kmod7). Based on the concept of equality and expansion of any number that is a power of 8, you can use a suitable integer to express 3 positive integers * as moxibustion = 8 «-1 ~ 1 + 8 ^ 2 _ 2+ &quot; + 8, +;?. . This equation can be written as "UU.. + is + corpse. (mod7) using modulo 7. In the binary representation of moxibustion, each -A represents three consecutive bits at position (m:3;) The three consecutive bits in the form of 3«_ + 2:3〇 are added up to 3 bits. Therefore, the final result can be reduced according to the invention, which can be as follows. "Technical Application" OFDM symbol index "Note: When 〇FDm symbol index" is the number of bits in the FLO system on all bandwidths, (1) ~~ ^5), (6-8) and (9-11) Seeing and dividing each of them to generate a 5-bit number 2. Next, grouping the obtained 5-bit numbers into bits (〇_2) and (4) again, and adding them to each other 4 bit number. 3. At this stage, ensure that the number of gains is between decimals. The t-stage can use a lookup table or an executable-final addition. The addition is performed right, and then the following step 4 is performed. 4. Add bit 4 to 3 LSBs. The result is guaranteed to be between 0 and 10. 133688.doc -32- 200922251 5·If the number is 7, map it back to 〇 (since 7 is the model at 7 ', the result is used as it is. This implementation uses 6 adders. You can also use 8 The car is turned on (for example, and the operation is reduced to 2 additions. The lookup table can be used to model its final result. 7. According to another exemplary aspect of the present invention, the operation is performed. 1 · Assume that (for example, 2's complement binary table is used | taste &lt; 1 clothing does not express OFDM symbol index n' and 2 „ from the number of bits long, select “group size (four) bits), Where w is greater than or equal to 2, and (4), h ' m is an integer, and & is an integer.

Alternatively, in the case of defense (for example) 3, the steps similar to steps 5 to 8 can be repeated. 11 If the resulting number is 7, map it back to 〇 (since 7 is 0) Mode 7). The result of the right is less than 7, and the result is used as it is now. Returning to Figure 2, in an exemplary process, the receiver of the receiver device can receive a signal. Demodulation transformer 2 (Η can perform demodulation on the received signal and provide the 〇FDM symbol to the processing system Shi can divide the (4) turn number into interlaces and map the interlaces to time slots using - a pilot interleave and / or a time slot interleave.

The processing system 314 or 206 (see Figures 2 and 3) of the transmitter or receiver device 302 or 200 includes a module 810 for including one or more pilot interlace vectors and a for including one or more distances Vector module 820. The processing system 314 or 206 also includes a module 830 for providing a first time slot interlace based on the one or more pilot interlace vectors and a method for interleaving based on the first time slot and the one or more distance vectors A module 8404 is provided for the second time slot interleaving. Figure 9 is a flow diagram illustrating one exemplary operation of providing time slot interleaving or providing communication at a transmitter or receiver device. In step 91, the processing system 314 or 206 (see Figures 2 and 3) of the transmitter or receiver device 302 or 200 can receive one or more pilot interlace vectors. At step 92, processing system 3 14 or 206 can receive one or more distance vectors. In step 93, it may provide a first time slot interlace based on the one or more pilot interlace vectors. Additionally, in step 940, processing system 314 or 260 may provide a second time slot interlace based on the first time slot interlace and the one or more distance vectors. A readable medium can be encoded or stored with instructions executable by the transmitter or receiver device or by the device device system, wherein the instructions include the code for steps 910, 920, 930 and 940 described above. As mentioned above, the hardware architecture can be implemented to implement a series of time slot-to-interlace mappings via the configuration of some hardware registers. The architecture supports time slot to interlace mapping with different pilot staggered patterns. The channel estimation capability and the Dougler elasticity depend on the pilot staggered pattern in an OFDM system such as FLO. With the above architecture, a single FL〇 receiver device can support slot-to-interlace mapping that can be deployed in different networks. The architecture also supports backward compatibility with FLO's empty intermediaries. According to one aspect of the invention, pilot observations obtained from multiple OFDM symbols may be required to correspond to as many distinct subcarriers as possible to ensure that channel estimates for the delay spread requirements of the system are met. In addition to the pilot symbols across a wide subcarrier array, it may be desirable to spread the data symbols between the pilot subcarriers in the OFDM system and the set of all available subcarriers so that the data symbols have channel estimates and frequencies. The benefits of diversity. Therefore, time slot to interlace mapping plays an important role in the 〇FDM system. The above-mentioned main hardware and software implementations are exemplary implementations. The technology is not limited to such implementations, and other suitable implementations can be used. The technology is also not limited to FLO systems and can be used in a wide variety of communication systems. Although the staggered patterns (2, 6), (0, 3, 6) and (〇, 2, 4, 6) are described above, these are merely examples and the present technology is not limited to these examples.
