200924401 IX. Description of the Invention: [Technical Field of the Invention] The following is generally related to wireless communication, and more specifically to determining a secondary synchronization codebook for selecting a secondary synchronization code for a radio network site. . This non-provisional patent application claims the SECONDARY SYNCHRONIZATION CODEBOOK FOR p E-UTRAN, which was filed on August 13, 2007 and named "E-UTRAN". The priority of U.S. Provisional Patent Application Serial No. 60/955,623, the disclosure of which is hereby incorporated by reference in its entirety in its entirety in its entirety in its entirety herein in [Prior Art] Wireless communication systems are widely deployed to provide various types of communication content such as voice content, material content, and the like. A typical wireless communication system can be a multiple access system capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmission power). U-examples of such multiple access systems may include a code division multiple access (CDMA) system, a time division multiple access (TDMA) system, a frequency division multiple access (FDMA) system, and orthogonal frequency division multiple_access ( OFDMA) systems and the like. In general, a wireless multiple access communication system can simultaneously support communication of multiple mobile devices. Each mobile device can communicate with one or more base stations via transmissions on the forward and reverse links. The forward link (or downlink) refers to the communication link from the base station to the mobile device, and the reverse link (or uplink) refers to the communication link from the mobile device to the base station. In addition, communication between the mobile device and the base station can be established via a single input 133839.doc 200924401 single output (SISO) system, multiple input single output (MIS) system, multiple input multiple output (10) MO) system, and the like. The ΜΙΜΟ system typically uses multiple (Ντ) transmit antennas and multiple) receive antennas for data transmission. The MTMO channel formed by Ντ transmit antennas and Nr receive antennas can be decomposed into Ns independent channels, and the independent channels can be referred to as S-channels, where each of the independent channels corresponds to “dimension” . In addition, the MIM(R) system can provide improved performance (e.g., increased spectral efficiency, higher throughput, and/or greater reliability) if the additional dimensions generated by multiple transmit and receive antennas are utilized. The improved performance, throughput, and guilt afforded by multiple transmission wireless access sites can also introduce additional system complexity. By way of example, where multiple base stations transmit within a common area and the transmissions are received by a single device, a mechanism for distinguishing between the transmissions may be required. In addition, a mechanism for distinguishing and/or identifying a base station and another base station component for identifying a base station and distinguishing the received transmissions may be utilized by utilizing channel synchronization. In some examples, synchronization may include - a primary time code (psc) including frequency and timing information for transmission and a human synchronization code (SSC) providing a base station identification code. In such examples, a device can distinguish and decode one or more transmissions in an eve transmitter environment by means of psc and / or c.

Many of the settings are described in the context of determining that - or a plurality of wireless channel characteristics and portions ^ provide handover (four) based on the magnitude of the received characteristics. Those skilled in the art should understand that similar techniques can be applied to other contexts. In the one or more aspects, the present disclosure provides reduced interference of multiple secondary synchronization code (SSC) transmissions in a multi-transmitter environment. The environment can be associated with a planned, semi-planned, and/or unplanned mobile communications environment. Typically, a Radio Access Network (RAN) base station (BS) utilizes synchronization codes to facilitate mobility with mobile devices (eg, cellular phones, cellular access laptops, multi-mode phones, personal digital assistants [PDA] and/or Or the like (OTA) communication. The mobile device monitors the synchronization code (and, in some instances, other portions of the OTA transmission) to determine when the relevant data is provided by Bs. In the case where many BSs are present in relatively small communication sites (e.g., such that the mobile device receives wireless transmissions from many BSs), the synchronization codes can interfere with each other, making it difficult to distinguish at the mobile device. Therefore, mechanisms for reducing or avoiding synchronization code interference can improve the reliability of mobile communications. According to some aspects, a specific mechanism is provided to generate ssc and disturb with 1&gt;_%11 phase 133839.doc -14· 200924401. When transmitted in a common action environment (e.g., a single action deployment site or multiple closely located mobile sites), the scrambled SSCs may be less likely to interfere with each other. In at least one aspect, the first set of sequences provided by the first mathematical expression can be free to generate ssc, and the scrambling code to disturb the SSC can be generated from different mathematical expressions. In addition, the sequence index of the scrambling code can be selected based on a primary synchronization channel (P-SCH). Various mechanisms can be utilized to generate disturbed ssc and reduce interference from multiple SSCs transmitted by multiple sources (e.g., BS). The ssc can be generated from a plurality of sequences selected from a sequence of matrices comprising a base sequence and a variant of the base sequence (e.g., a cyclic shift sequence). The scrambling code can be used to (4) the base sequence, the selected sequence, and/or to reduce the interference of the OTA SSC. As an example, a pair of selected sequences may first be disturbed by the scrambling code, which may then be combined to form a full length scrambled SSC sequence (eg, by interlaced sequence pairs), which may be disturbed The ssc sequence maps to the OTA message. In another example, the pair of sequences can be first interleaved to form an undisturbed full length sequence and then the full length sequence is subsequently disturbed by the scrambling code&apos; and then mapped to the transmission. In other examples, the base sequence can be scrambled such that the sequence matrix contains the disturbed base sequence and its disturbed variations. In this example, the matrix is selected - the sequence of the scrambled, interleaved to form a growing SSC sequence and mapped to the 〇TA message. The disturbed SSC sequence can produce reduced interference of transmitted ssc and improve the reliability of the transmission for planned, semi-planned or unplanned mobile base station deployment. In accordance with one or more other aspects, a mechanism for generating a PSC-based scrambling I33839.doc 200924401 code that randomizes interference between encoded signals is provided. Utilizing a plurality of sequences (e.g., three sequences) to generate a scrambled sequence for one or more of said sequences can comprise a collection of full length sequences (or, for example, modified full length sequences, such as truncated-bits). Or a collection of semi-long sequences (which are attached to other semi-long sequences of the set). In at least one aspect, the self-threshold sequence polynomial produces a collection of full-length and/or half-length sequences. In another example, a set of full length and/or half length sequences can be generated from a plurality of Μ sequence polynomials. In at least one additional aspect, a PSC-based scrambling code is generated from the three half-length sequences, which are generated from polynomials of different (d) polynomials that produce SSCs. In accordance with one or more other aspects, an SSC codebook for generating an SSC for a multi-transmitter mobile site is provided. The SSCs can be generated from various sequences of a sequence of matrices. The sequences can be selected based on the s and/or associated determinations of the ssc caused by the self-pairing sequence.

The base station (306) can communicate with the mobile device 304 by exchanging OTA messages. The OTA message sent to mobile device 304 typically includes one or more synchronization messages to facilitate this communication. For example, the PSC can be utilized to indicate where the data is wrapped in the message, the length of the message, the frequency of synchronization, or the like. The SSC can provide prior information as well as the identification code of the transmission base station 306. Thus, the SSC can be utilized by the mobile device 304 to distinguish one base station (306) from another base station (306) in the multi-transmitter station 306. In the case where multiple OTA messages are transmitted by multiple base stations, interference between messages can be caused in parallel at substantially 133839.doc •23-200924401. Interference with synchronization information can cause loss of information, increased power consumption at the mobile device 304, and communication inefficiencies. To reduce the occurrence of interference, SSC generator 302 may utilize one or more scrambling codes to reduce the likelihood that two sscs will interfere with each other at the receiving device (3〇4). System 300 can further include a logic processor 〇8 that generates a sequence matrix for generating one or more of the base stations for RAN 306. For example, sequences, sequence pairs, sequence triplets (4), prisons, etc. can be used to generate the present. In the aspect, a sequence pair of sequences of length 31 (e.g., a binary sequence of 31 binary bits) is utilized to generate a 62 bit s S C . The sequence pairs of the creasable whites, corpses & amps are selected from the matrix generated by the logical processor 3〇8. In the -example, the sequence matrix can be generated from a single-base sequence of length 3i. The sequence can be derived from a suitable polynomial expression. In "his grievances, the logical processor uses a polynomial expression sequence from a polynomial expression that is used by a J&M; and the data is used to generate a sequence for the SSC scrambling code." &quot; The polynomial,,,, 疋, and 产生, which can be used to generate a basic Μ sequence, can have a form of 2 + 1 on 2), where GF(7) indicates the Galois field of the digits (GaiGisField). The result of the second is once generated by the logical processor 3〇8—a variant of the base sequence to fill the sequence matrix. In the case where the number of bits that are equal to the number of bits in the base sequence is formed, a substantially basic sequence is generated. Contains 31 digits, then n (eg 'if number variant').

System 300 may further include a data transformation module 31〇 A common one-ary interfering IL code is used to disturb a sequence of δ ν ν of a sequence of matrices. In at least one aspect, a scrambling code can be generated by a sequence module 312 of sequences derived using a self-common polynomial expression. The polynomial expression and/or the derived sequence may be based on a PSC associated with wireless communication (eg, a '〇ΤΑ message). As an example, an index derived from the PSC may be utilized to select a sequence pair, a sequence triplet, or the like. (e.g., 'self-scrambling code sequence matrix') to generate a scrambling code. The selection of the PSC-based scrambling code sequence can provide reduced interference for the transmission of multiple SSCs. It should be appreciated that data transformation module 310 can utilize the scrambling sequence to disturb 133839.doc -25- 200924401 The component of ssc, SSC (for example, a sequence pair forming a ssc, a sequence of a sequence triplet, etc.) or a sequence of the sequence matrix itself. In a specific example, the data transformation module 310 can Disturbing the underlying sequence used to generate the sequence matrix. It also inherently disturbs the derived sequences (eg, cyclic shift variants) used to form the disturbed base sequence of the sequence matrix. Thus, the disturbed sequence can be used (eg, borrowed The sequence matrix is formed by utilizing the disturbed base sequence or its variants, undisturbed sequences (eg, by utilizing undisturbed base sequences and variations thereof), or both, as described in more detail below, disturbed The sequenced matrix is selected by the logical processor 308, interleaved by the multiplex module 314, and mapped by the transport processor 316 to the OTA message. In other examples, the scrambling code can be applied to one of the sequence matrices selected from the unscrambled Or a plurality of undisturbed sequences. For example, the data transformation module 31 can perturb a plurality of short sequences selected from the matrix, and the short sequences are followed by a multi-mode 314 are interleaved to form a full-length SSC sequence. As another example, the multiplex module 314 may first interleave a short sequence, and then provide the resulting full-length sequence to the data transformation module 3丨2, and the data transformation module 3丨2 disturbs the full length. The disturbed sequence is then used as the SSC for one or more base stations (3〇6). This technique is known in the art or is provided by the content provided herein. It is understood that various types of scrambling can be generated by the sequence module 312. As mentioned above, the sequence module 3 12 can generate various sequences (eg, M sequences) from a common polynomial expression or a different polynomial expression. In the process of generating a disturbance based on three sequences of length 63, wherein each sequence of length 63 is truncated by one bit to form a disturbance 133839.doc -26- 200924401 garbled (or, for example, one The bit is changed to 〇 and mapped to a radio transmission tone. In another example, a scrambling code based on three sequences of lengths of 31 is generated, and using t complex to generate three scrambling codes of length (eg, where B is a sequence of length 3丨, the repetition may have The form may form a plurality of scrambling code sequences from a single-polynomial expression in at least a particular aspect. In the aspect, the polynomial expression may have the form 1+ΧΛ2+ΧΛ3+ΧΛ4+ΧΛ5. The resulting scrambling code can be represented by C(0, n)

sequence. As a specific example of a suitable scrambling sequence, C(0, n) may indicate the following sequence: The above sequence C(0, n) may represent a base sequence. A cyclic shift variant of the underlying μ sequence (see, for example, Figure 4 below) can be defined as c(k,n)=c(0,(n+k) mod Ν). Therefore, a scrambling code of length 63 can be obtained as follows: [C(u, 〇)Au, 0), where 〇 can be mapped to a DC carrier tone of frequency-based transmission. It will be appreciated that other length codes can be generated by setting a suitable value for kAn of C(k'n) (e.g., having a suitable value greater than 〇). For a condition of length 〇, a distinct scrambling code can be generated by selecting a distinct value of '1&quot;. The value 乂 can be selected based on the desired number of sets of scrambled code sequences of the sequences. For example, five, ten, and twenty variations of the basic sequence can be selected. For 31 possible sequences, U, can correspond to the set {〇, in at least the state order, the sequence modulus formula..., 30} 〇 group 312 can be from 133839.doc -27- 200924401 C(k,n)=c (o, (n+k) mod three disturbed sequence I scrambling code can correspond to the following three v values ···{0, 10,2〇}, so use the base (four) sequence, the tenth cycle of the base sequence Shifting variants and the twentieth-soil shifting variant of the foundation (4). The resulting three scrambling code sequences are: C(2(4),

The scrambling sequence can be used to generate a scrambling code having a varying length (e.g., a scrambling code of length 62) and combined with the ssc sequence. The scrambled sequence is mapped to a wireless transmission as discussed below. A significant reduction in interference between transmitted sscs can be achieved by utilizing the scrambling sequence of the common multi-W term expression. System 300 can further include a transport processor 316. Transport processor 316 can map the SSC to the component of the OTA message. Specifically, the SSC can be mapped to a subcarrier channel of a frequency-based message (eg, fdm, 〇fdm, OFDMA), mapped to a code-based message (eg, CDMA, CDMA-2000, Wideband CDMA [WCDMA]) On the division code, the appropriate time is mapped to the time-based or combined system information of the time-based message (for example, TDMA) (for example, TD-CDMA, TD-SCDMA 'UMTS-TDD, FDMA/TDMA/FDD, etc.) On the subcomponent. The OTA message can be received at the mobile device 304, and the mobile device 3〇4 can utilize suitable techniques for decoding the message and ssc. In at least one example, the mobile device 〇4 can utilize the process for decoding ssc that is substantially inverse to the process used by the SSC generator 3〇2 to encode/disturb ssc. The instruction to decode the ssc can be pre-loaded into the mobile device 3〇2's software from the network patch or the like (in the case of the network (4) of the service provider) / or hardware repair process 2) planted or included. Within the message (eg, message preamble or the like, the description system can provide significant benefits for wireless communication. SSC scrambling:: the SSC scrambling code generated by the term expression and indexed based on the corresponding PSC can be Resulting in reduced interference from the SSC transmitted by the land σ (3〇6). The result can have even more than two (3〇6#十. cups, where a larger number of backbones are 9 semi-planned or unplanned deployments In this deployment, sτ w &gt; can be degraded. Therefore, system 300 provides increased efficiency and reliability for unfavorable wireless environments.

As depicted by the sequence matrix 4, the cyclic shift is a unit number shift, with the ^= arrow shifting each sequence--position, or a moment=sequence variant. Thus, X male discriminator $ becomes the base sequence base sequence bit 1 is -1, and its normal-cycle shift variant (depicted at column 2 of the matrix) has the same in the second soil /: In addition, each bit of the base sequence is shifted to the _ 133839.doc -29- 200924401 by the right next row in the % shift sequence. It should be understood that it can be used alternatively. Multiple_ring shifts such that the alternate shift single row 'per-bit is shifted by two rows, three rows, etc. relative to the previous sequence. The extra columns of the matrix present a further shift of the base sequence. Therefore, the second cyclic shift The bit of the sequence (column 3) is shifted by two lines from the base sequence (8), and is performed by per-column and the like. For a matrix having L, rows, based on the sequence length, L, the matrix may contain at least L, a unique sequence, including the base sequence and the L·丨 single-cyclic shift variant of the base sequence. As described herein, this sequence can be used to generate synchronization codes and/or scrambling codes. In the case of 丄, matching the desired code length, a single sequence of matrices 4 可 can be used to generate such codes. Alternatively, a plurality of sequences of the matrix 400 may be utilized to generate the code if 'L' is shorter than the desired code length. As an example of the foregoing, a desired code length (e.g., ssc prolonged) is 62 bits. In the case where L is equal to 62, a sequence of the matrix 400 can be used to form a sequence in which the code H is equal to 31, and the sequence of the matrix 4 〇〇 C. can be interleaved to form the code. In the case where |L, equal to 21, the interleaved sequence triplets (which cause the ones in the sequences to be truncated - one bit (7) to produce a (four) code. It should also be understood that the combining bits can be carried and/or The bits are repeated to utilize a substantially similar sequence length (eg, a sequence of length 63 can be truncated by one bit to form a code of length 62, or a single bit can be repeated or truncated to utilize the length. 30 or a sequence of lengths of 32 to form a code of length 62, etc.) For the deployment of dense base stations operating at a common geographic location at a number of base stations (see, for example, Figure 1 above) It may be beneficial to have a shorter than 133839.doc * 30 - 200924401, triplet, etc. This comparison may be from the sequence matrix 400. For example, if L, equal to 62 and the length of the target code length The alignment of the sequence is due to the fact that more unique sequence pairs, triplets, etc. are taken with a single sequence, and there are 62 unique single-sequences formed in the matrix 400 with Li = 3i and the presence of 961 The SSC length of a different ssc is 62 bits. In 62 different SSCs. However, for a SSC of length 62, 96U3P2) sequence pairs. As another example, 'l = 2 〇, or 'L = 21' (using bit repetition or truncation) respectively exist to produce different ssc

8,000 or 9261 sequence triplet combinations. Therefore, by asking about μ. The length selects the appropriate sequence length and utilizes pairs of sequences, triplets, etc., and the number of unique codes generated by the matrix (400) can be increased. In at least one specific example of the claimed subject matter, the matrix 4〇〇 is a square matrix having 31 Μ sequences of length 'L1 equal to 31, and the base sequence is from χΑ5+χΑ2+1 form having GF(2) A binary sequence produced by a polynomial expression. Moreover, the additional sequence is a single cyclic shift variant of the base sequence (e.g., as depicted by the arrows of sequence matrix 400), the pairs of sequences can be selected and interleaved to form various dissimilar SSC codes. As described elsewhere herein, various ways are possible. Implementing SSC scrambling (see, for example, Figure 3 above). In one example, the selected pairs can be interleaved to form a sequence of length 62 and then scrambled. Alternatively, the selected sequence of length 31 can be scrambled and then interleaved to form A sequence of length 62. As a further alternative, the base frame sequence can be scrambled such that each cyclic shift variant of the matrix 400 is also disturbed. The disturbed sequence pairs can then be selected and interleaved to form a ssc code of length 62. In the case, the bit &quot;T is added to a code of length 62 to form a code of length 63, where the bit 133839.doc 31 200924401 maps to the DC carrier tone of the wireless transmission. Therefore, various mechanisms can be utilized to reduce Interference of overlapping wireless messages received at the device, thereby providing improved reception and total communication, and potentially reducing power at the receiving device (eg, by avoiding heavy Transmission. Figure 5 depicts a block diagram of an example system 500 that provides reduced interference of transmitted ssc in a multi-transmitter mobile site. More specifically, system 500 provides a sequence combination for selecting the resulting SSC. The selective code is thin. In some aspects, the 'sequence combination can be based on the basic characteristics of the resulting ssc. Therefore, improved wireless transmission can be achieved by correctly selecting the SSC that produces the desired characteristics in the mobile communication environment. An SSC index selector 5〇2 is included that identifies one or a plurality of SSC sequences or sequence groups for generating base stations 5〇4 that can be assigned to the RAN (not depicted, but see FIG. 3, 306) (eg, a sequence pair). The SSC index selector 5〇2 may comprise a logical processor forming a sequence matrix, the sequence of sequence groups may be selected from the sequence matrix. Available—basic sequences and many variations of the base sequence Forming a sequence matrix. In at least one aspect, the base sequence is of length n+1 - 隹 丨 λ / ί -, the 进制 M sequence ' and the matrix contains the base sequence: the base sequence _ cyclic shift Bit variant (eg As shown in Figure 4 above, the index module 5°8 can assign an index to the sequence and/or sequence group of the sequence matrix. The sequence can be selected by the index of the folder' In the case of the present disclosure, the index module assigns a general (η+1) index, where the parent is "for a single-sequence, the assignment is generally Therefore, for the sequence pair, the assignment is general (n+ir2 indexes, and so on. 133839.doc -32- 200924401 in the presence of more than the base station (504) of the base station (504) In the case of a sequence combination, the trimming module 510 can select a sequence/sequence group based on the characteristics of the resulting SSC. These characteristics can be based on the results of the signal simulator. For example, the 忒k唬 simulator can determine SSC interference, power loss, cross-correlation, and similar characteristics. The sequence/sequence group of SSCs having the desired characteristics (such as low PAPR) can be selected to generate sSc. As a specific example of the aspect of the system 500, the logical processor 〇6 defines a sequence matrix having 31 sequences of length 31. A sequence pair of matrices may be represented by (u, v), where both u&amp;v have values {〇,...,3〇}. A number of sscs of length 62 can be generated based on the sequence pair (u, v) of the sequence matrix. The programming module 508 assigns (n+1) Λ 2 or 96i indices to the 961 distinct sequence pairs of the sequence matrix. These indexes can be generated using an algorithm with the form r = u * 31 + v. In one aspect of the example, the trimming module 51 is selected based on the characteristics of the SSC signals including sequence pairs (eg, including scrambling (such as 'provided by a common PSC-based scrambling code k) and interleaving the sequences) 170 out of 961 distinct indexes. One or more of the selected SSCs (eg, a pair) may then be converted into a radio frame by the transmission processor 5 12 (eg, using a modulator, signal encoder, etc.) to resolve the radio frame.

Different carrier tones derived from one or more of the 340 resulting SSCs (e.g., different carrier tones of a pair of SSCs) may be converted by the transmission processor 512 into a radio frame to resolve the frame boundaries of the radio frame.

For example, the first set of sequences V of length 31 can utilize the indices {0, 1, 2, ..., 19}. The second set of sequences of length 31, v, may utilize the indices {11, 13, 14, ..., 30} to minimize the overlap between the resulting SSC, u, and v sequences. In some instances, the reduced cable weight provides a reduced interference between the transmitted codes. As described by the woman, the system 5 can provide an ssc codebook that selects ssc based on the basic characteristics of the transmitted step letter 35. The result of the Xiao can result in improved signal reception, reduced signal reduction (e.g., less data retransmission requests) and lower power consumption for such terminals used in the operation of the terminal device. Thus, significant benefits can be provided by the system for use in a mobile communication environment. Figure 6 illustrates a block diagram of an example system 6A utilizing an ssc codebook as described herein for reducing interference between transmissions. The selection of the ssc code can be compared to the transmission power and/or cross-correlation characteristics of the simulated sSC and one or more 〇 35 limits. The resulting ssc can be tuned to wireless transmission (e.g., radio 11 busy) to resolve the frame boundaries of the s-transmission. Because the SSC selection is based on the basic SSC characteristics&apos;, improved power and/or related characteristics can be provided by system 600 for mobile communications. System 600 includes an ssc index selector 6〇2 that indexes the sequence and/or sequence groups of the sequence matrix. The index selector can select one or more indices based on the power and/or cross-correlation properties of the simulated SSC code 604 caused by the particular sequence of free-index identifications. The quality of the determined power and/or cross-correlation properties can be assessed based on a comparison with one or more thresholds. For example, the pruning module 606 can adjust the selection of a particular index based on a comparison of the SSC PAPR to the PAPR threshold value (e.g., based on a nominal OFDM symbol), a comparison of the SSC cross-correlation and the cross-correlation threshold, or both. Therefore, the resulting SSC having a predetermined quality characteristic can be produced. System 600 can utilize a signal simulation module 608 to determine the PAPR of the simulated SSC (604) caused by the sequence of free identification of a particular index. The signal simulation module 608 can compare the determined PAPR with the threshold PAPR and forward the result to the trim module 606. A relatively low PAPR is generally beneficial for wireless transmissions (e.g., as compared to transmission of typical frequency modulated signals), thereby causing negligible impact on downlink transmissions in many instances. Thus, the threshold may generally specify a certain maximum acceptable PAPR, an acceptable range within the desired PAPR (eg, within 3 dB of the desired PAPR), and a number of SSCs below the desired PAPR (eg, have lower than desired) 30 SSCs of the PAPR value of the PAPR) or the like, or a suitable combination thereof. The system 600 can also utilize a signal correlation module 610 that determines the interaction correlation factor of the simulated SSC (604) caused by the sequence of a particular index identification. The signal correlation module 610 can compare the determined cross-correlation and interaction-related thresholds to assess the quality of the simulated SSC 604. Signals that are strongly correlated with other signals can often exhibit high interference, so minimal interaction correlation can be desirable. Thus, the pruning module 606 can adjust the selection of a particular sequence index based, at least in part, on the interaction correlation being equal to or below the threshold correlation. In some aspects, the pruning module 606 can adjust the selection of a particular sequence index based on a combination of PAPR results and interactivity related results. For example, if the simulated SSC (604) has a PAPR below the threshold PAPR and a low 133839.doc -37-200924401 at the relevant threshold (4), the τ selection is associated with the simulated (10) sentence. Index. As described, System_Provide - is used to select an index of the sequence matrix to provide a convenient mechanism for beneficial PAPRw or low cross-correlation properties, resulting in improved wireless transmission and reliability in many instances. 7 depicts a block diagram of an example system 7A in accordance with aspects of the present disclosure, the system 700 including a base station 7〇2 and a unit (four) device. In at least the aspect of the disclosure, the base station can determine the appropriate current code and/or the scrambling code to reduce the interference of the transmitted synchronization information. In particular, it can be implemented by base station 702 for generating and scrambling ssc for generation. The scrambling code (e.g., based on three lengths of 3kM sequences) and various mechanisms for selecting sequence indices based on the characteristics of such SSCs. Thus, system 7 (10) facilitates improved operational communication by providing improved transmission characteristics for OTA messages received at one or more mobile devices 7 〇 4 in a mobile communication environment.

In one example, sequence module 724 can generate three suitable M sequences of length 63 or length 31 to form a scrambling code. For example, three Μ sequences can be generated from the base Μ sequence and the cyclic shift variant of the base Μ sequence. In addition, at least some of the patterns can produce at least 20 cyclic shift variants of the base sequence, and the three "sequences can include a base μ sequence, a tenth cyclic shift variant, and a twentieth cyclic shift.

The mobile handset 802 includes at least one antenna 8〇6 (eg, a transmission receiver including an input interface or a group of such receivers) that receives signals (eg, including synchronization information related to facilitating remote wireless communication) and The received signal subscribes to the receiving 808 of a typical action (eg, filtering, amplification, down conversion, etc.). Specifically, the antennas 8〇6 and the transmitters 83〇 (collectively referred to as transceivers) can be used to facilitate the exchange of wireless data with the base stations 8〇4. Antenna 806 and receiver 8A8 can also be coupled to a demodulation transformer 81G that can demodulate the received symbol line to be provided to processor 812 for evaluation. In particular, the demodulation transformer 81 can extract at least synchronization information from the received wireless transmission. For example, for frequency-based transmission, the mutator 810 can extract the synchronization slot from the subcarrier frequency of the wireless transmission. In one aspect, the synchronization information can include at least - SSC, the at least one = step Contains at least two sequences that are scrambled using a common PSC-based binary scrambling code. A signal processor 814 can utilize a common PSC-based binary descrambling code to unpack the column containing the received ssc: the descrambling "can be substantially equivalent to being utilized by the base station or can be paired with it ( For example, the inverted scrambling code). In at least one aspect of 133839.doc 4! 200924401, decoding the synchronization resource" J 7 is related to a data processor 820, which is the first The production of your &amp; + _ shift is applied to the first of the two sequences associated with the SSC and the second, music-extension % shift is applied to the second of the two sequences. In this (equal) aspect, signal processor 814 can then apply the descrambling code to the first phase and the shifted second sequence to decrypt the SSC. Upon decoding the received SSC, a logical processor 818 can extract the identification information associated with the device (10) 4) transmitting the received data. This poor message can be utilized to further decode the received data (e.g., payload information) and/or facilitate communication with the transmitting device (804). It should be appreciated that the processor 812 can control and/or reference one or more components (10) 6, 810, 816, 822 of the mobile handset 802. In addition, processor 812 can execute - or a plurality of modules, applications, engines, or the like (814, 818, 820) that contain information or control related to performing the functions of mobile device 8.2.

Road transmitter (804), or the like. The mobile handset 802 can additionally include a memory 816 operatively coupled to the processor 8丨2. The memory 816 can store two materials to be transmitted, to be received, and the like. Further, the memory 8丨6 can store the modules, applications, engines, etc. (814, 818, 820) executed by the processor 8丨2 above.

Sub-components may also be implemented to be communicatively coupled to one of its components rather than to components within the previous generation of components. In addition, it should be phonetic, two or more components can be combined into a single group 2 that provides collective functionality: the signal analog module 608 can include a signal correlation module 61 or a signal correlation group 6 10 can include a signal simulation module 6〇8, to facilitate the determination of the peak average power and cross-correlation of the SSC by the single-component. The components can also interact with one or more other components not specifically described herein but known to those skilled in the art.

The recipes described above are based on the flowcharts of References 9 through U to better understand the methods that can be implemented in accordance with the disclosed subject matter. Although the method is shown and described as a series of blocks for the sake of simplicity of explanation, it should be understood and understood that the claimed subject matter is not limited by the order of the blocks, as some blocks may differ from those depicted herein. And the order in which the order is described occurs and/or occurs concurrently with other blocks. In addition, all of the blocks described are not required to implement the &lt;RTIgt; In addition, it should be further appreciated that the methods disclosed hereinafter and throughout the specification can be stored on an article to facilitate the transport and transfer of the methods to a computer. The term &quot;article&quot; is intended to encompass a computer program accessible from any computer readable device, device in conjunction with a carrier, or storage medium. 9 depicts a flow diagram of an example method 900 for reducing interference of multiple ssc transmissions in accordance with aspects of the present disclosure. At 902, Method 9 can generate a sequence of matrices. The sequence matrix can comprise a sequence of sequences generated from one or more polynomial expressions. In at least one aspect of the present disclosure, the m-sequence is generated from a polynomial expression having the form χλ5+χλ2+1 on GF(2). In addition, the Μ sequence may comprise a base sequence and various variations of the base sequence such as provided by cyclically shifting the base sequence. At 904, method 9 can scramble at least one sequence using a psc-based scrambling code associated with a wireless communication. The scrambling code can be generated, for example, based on a sequence identified by an index associated with 133839.doc-44-200924401. In one aspect, the at least one sequence that is scrambled using the scrambling code can include multiplexed to form a pair of SSC sequences. The pair of μ sequences can be disturbed before or after the multiplex. In another aspect, the base sequence of the sequence matrix above may be the at least one sequence disturbed at reference numeral 9〇4 such that each variant of the disturbed base sequence is also disturbed. Therefore, according to this aspect, the sequence matrix contains the disturbed sequence. Ο

At 906, the method 9 can generate an SSC based on the scrambled μ sequence. As indicated above, it is possible to multiplex multiple sequences (eg, sequence pairs, sequence triplets) by truncating the SSC of the desired length (eg, length 62), truncating one or more of these sequences Genes, repeating one or more of the sequences, or a combination thereof or the like to generate ssc^ at 9〇8, method 900 may map the SSC to a subcomponent of the 〇TA message (eg, subcarriers for OFDM transmission) Channel). The method 900 produces using a psc-based scrambling code to scramble the π. Improved interference characteristics for wireless communication are available. It will be appreciated that the polynomial line that can be used to generate the SSC is different from the polynomial line that is different from the polynomial used to generate the ssc. In at least the (four) towel, the polynomial of the code has the form of +ΧΛ3+ΧΛ4+ΧΛ5. In addition, this polynomial can be utilized to generate a basic scrambling sequence. A bitwise variant of the underlying scrambling sequence can be generated to provide the H sequence (4). In one of the present disclosures, twenty or more of the scrambling sequences are generated and combined with the basic scrambling sequence to form a scrambling sequence matrix. According to this, the self-interfering gas sequence matrix In general, the three sequences produce a disturbance of 133839.doc *45- 200924401. As an example, the basic scrambling sequence, the tenth cyclic shifting variant of the basic scrambling sequence, and the twentieth cyclic shifting variant of the underlying scrambling sequence can be utilized. To generate a PSC-based scrambling code. Figure 10 depicts a flow diagram of a sample method 1000 for scrambling 〇TA ssc transmissions in accordance with one or more aspects. At 1002, method 1 can be as described herein. A sequence of matrices is generated. At 1004, method 1000 can select two sequences from the matrix to produce an ssc. The sequences can be selected based on characteristics of the SSC code caused by the selected sequence. According to a specific example, the special The biometric may include a PAPR of the SSC code, an interactivity correlation factor of the SSC, or a suitable combination thereof. At 1006, the method 1000 may determine whether to first scramble or first multiply the sequence. The situation combines the push/angle interference characteristics of the resulting ssc code with the primary wireless transmission characteristics of the RAN (e.g., multipath scatter, signal reflection/refraction, or the like as known in the art of radio frequency propagation and/or mobile communication techniques). If the sequences are first multiplexed, the method 丨 can proceed to 1014, and if the sequences are first disturbed, the method 1000 can proceed to 1008. As described herein (eg, see Method 9〇〇, above), Method 1000 can generate a PSC-based scrambling code from a sequence matrix generated from one or more polynomial expressions. At 1〇1〇, a scs-based scrambling code can be utilized to scramble the two selected from the sequence matrix. The sequences may be interleaved to form an ssc. The ssc may be mapped to an OTA message and transmitted in conjunction with one or more wireless communications. At 1014, the method 1000 may be interleaved from the sequence matrix. The two sequences form a full length sequence. At 1016, a full length scrambling code can be generated as described herein 133839.doc -46 - 200924401. At 1018 ' can be utilized at reference numeral i〇i6 Production The full length sequence is disturbed by the scrambling code. Finally, at 1 〇 2〇, an SSC can be generated from the disturbed interleaved sequence, which can be mapped to the OTA message discussed above. Figure 11 illustrates at least one aspect A flowchart of a sample method 1100 for generating a scrambled ssc. At 1102, method 1100 can generate a sequence from a polynomial expression. In some examples, the polynomial expression can have a GF5 on GF(2) +χΛ2+1 form. At 11〇4, the method can use the PSC-based scrambling code to disturb the Vi sequence. A Psc-based scrambling code can be generated from one of a plurality of scrambled polynomial expressions or a plurality of scrambling sequences. According to at least one aspect, the scrambling polynomial expressions can comprise a single expression having the form 1+ΧΛ2+ΧΛ3+ΧΛ4+ΧΛ5. t. At 1106, the scrambled μ sequence is cyclically shifted n times to produce n distinct distorted variations of the disturbed sequence. The disturbed μ sequence and the η distinct distorted variants can be compiled into a disturbed sequence matrix. At 1108, both of the scrambled sequences of the scrambled sequence matrix are selected to form -SSC. As described herein, the selected sequences can be multiplexed to form a full length scrambled sequence. It will be appreciated that the two selected sequences may be based on the basic characteristics of the ssc derived from the sequences. In one aspect, the basic characteristics include pApR as ssc compared to the PAPR threshold. In the other aspect, the basic characteristics include interaction correlation factors as compared to the associated threshold. In a re-scenario, the basic characteristics include the appropriate combination of zeros described above. In at least one other aspect, the two selected sequences may be based on a predetermined number of 133839.doc -47 - 200924401 desired SSCs. As a specific example, as discussed above, where the scrambled sequence matrix comprises 31 scrambled sequences having a length that is substantially half the length of the desired SSC code, may be based on paPR and/or parent Related features to select 17〇 or 34〇 sequence pairs. Selecting the SSC sequence in this manner can provide reduced interference with the transmitted synchronization information, potentially reducing the power consumption of the receiving device and improving the communication in the mobile communication environment.
