Wireless communication devices are becoming smaller and more powerful to meet the needs of consumers and to improve portability and convenience. The increase in processing power in mobile devices such as cellular phones has led to an increase in the demand for wireless network transmission systems. These systems typically cannot be easily updated with the cellular device on which they communicate. The extension of the performance of the device may make it difficult to maintain an older wireless network system in a way that helps to take full advantage of the performance of the new wireless device. Wireless communication systems typically utilize different methods to generate transmission resources in the form of channels. These systems can be a code division multiplexing (CDM) system, a frequency division multiplexing (FDM) system, and a time division multiplexing (TDM) system. One of the commonly used variants is the Orthogonal Frequency Division Multiplei (〇FDM), which effectively divides the overall system bandwidth into multiple orthogonal subcarriers. These subcarriers can also be referred to as tones, intervals, and frequency channels. The available data can be used to adjust each of the winter gates and the mother field carrier. Each subcarrier can be used in all or part of the far-end 幻 连续 连续 continuous time slice or time slot with a time-based technique. Each user can provide a combination of one or more time slots and subcarriers for transmission in a predefined time zone, field & second, X week/month or frame. And receiving information. The frequency hopping scheme can be usually a symbol rate U-time hopping scheme or a block hopping scheme. The code-based technique typically transmits data over a number of times at any time within a range of frequencies. In general, data is digitized and propagated over the available bandwidth 'where multiple users can overlap on the channel and can be assigned to individual users - only - serial code ° user can be in the same wide frequency block of the spectrum Medium transmission, in which each-user signal propagates over the entire bandwidth by its respective unique-propagation code. This technology can be shared, where - or multiple users can transmit and receive simultaneously. This sharing can be achieved by spectrally modulating the bits of the spectrum, where the user's bits are encoded and propagated across a very wide channel in a pseudo-random manner. The unique sequence codes associated with the phase identification are received and randomized to collect a particular user's bits in a coherent manner. Time-sharing and/or code-coding a typical wireless communication network (eg, using frequency division, terminal. A typical base station can simultaneously transmit for broadcast, technology) including one or more base stations providing a coverage area, and One or more actions (eg, wireless) final multicast and/or single or another-mobile terminal are transmitted and received within the coverage area. In these systems, a scheduler is used to assign bandwidth and other system resources. The data stream of the broadcast service, which is a stream of data that can be independently received and concerned with a mobile terminal. An mobile terminal within the coverage area of the base station may be interested in receiving one, more than one, or all of the data streams transmitted from the base station. Similarly, the method and apparatus used by the mobile terminal to transmit data to the base for communication and/or use of interference information will facilitate efficient use of the bandwidth. Therefore, there is a need to effectively communicate new and/or improved methods of interfering information and, as the case may be, to use new methods of communicating interference information. ,. 122119.doc 200812282 SUMMARY OF THE INVENTION A wireless communication method and apparatus for efficiently communicating control information including interference information is described. A communication device (e.g., a base station) measures interference information (e.g., other sector interference information). The communication device generates a preamble including a plurality of indication symbols. In some embodiments, at least one of the pilot symbols includes interference information. In some embodiments, the preamble is part of a timing/frequency structure (e.g., a reproduction superframe structure), including a preamble and a plurality of subsequent frames. In some embodiments, some of the subsequent frames are used to transmit traffic data. In some embodiments, the preamble is a small OFDM symbol for transmitting pilot signals, system configuration, and/or paging information. Adjacent blocks, and at least one of the unsigned symbols carries interference information. The communication device transmits the preamble, thus broadcasting the interference information to nearby access terminals, which can use this information to make savvy transmission control decisions. An access terminal receives a preamble comprising a plurality of index symbols, at least one of which includes interference information. For example, in some embodiments, interference information is carried via one or more of the 〇FDM symbols. The interference information may be carried via another sector interference channel corresponding to all or part of one or more OFDM pilot symbols. In this embodiment, a pilot OFDM symbol identifying the sector of the transmitter is used to carry other sector interference. Thus, in some but not necessarily all embodiments, a 〇FDM symbol carrying information identifying the source of the transmitted symbol also carries interference information corresponding to other sectors. In an exemplary embodiment, the interference information is conveyed by a value that has been used to generate a phase offset multiplier in the pilot symbol. The access terminal recovers the interference information from the received preamble and controls the signal transmission based on the interference information recovered 122119.doc 200812282. In response to the recovered interference information, some exemplary signal transmission control operations include: suppressing the transmission, adjusting the transmission power level, and adjusting the data transmission rate. 3

capture channel, for Capture timing and other information; and (^) an additional sector interference channel, including indicators from sectors whose interference is measured relative to other sectors. In addition, in some aspects, the message for the channel in the hyperframe preamble may span multiple hyperframe preambles of different hyperframes. This can be used to improve decoding performance by configuring a larger lean source to some high priority messages. As shown in Figures 2A and 2B, the hyperframe preamble is followed by a series of frames. Each frame may include the same or a different number of 〇fdm symbols, which may constitute a plurality of subcarriers that may be simultaneously used for transmission over some defined period. Additionally, each frame may be in accordance with a symbol rate hopping pattern ( Wherein the user or the block hopping mode (where the user hops in one of the 〇FDM symbols) may be in the forward or reverse link (or the non-adjacent QFDM symbol refers to the user) or the block hopping mode. operating. The actual block or _ symbol may or may not be frequency hopped between frames. Figure 3 is a schematic diagram of the frequency-to-time pattern of the descriptive super-coded block of the wireless communication system of the child-in-one wireless communication system in the - or multiple aspects, by the super: 122119.doc -14- 200812282 The bandwidth can be red 25 MHz. In other aspects, it can be 2·5 MHz, 5 Μ ίίζ or some other bandwidth. In Figure 3, the super code frame 3〇1 carries a first additional channel (including a facet symbol - a first part 3 〇 2) and a second additional channel (including a second part of the OFDM symbol 3 〇 4 and 〇 fdm symbol 鸠, 纲, 31 〇, 312, 314). The channel carries a wide range of static parameters 'for example, 'cycle preamble duration, number of guard subcarriers, and super:::. In one aspect, 'the first additional channel is used for initial wakeup. At ^ g % 1 The first additional channel is encoded on several super-coded frames (for example, 16 super-coded frames). ^ The I-channel carries enough information to enable an access terminal to demodulate the front-end link frame. Link information (eg, data transmission). In other aspects, the second additional channel may include a control with the frequency hopping pattern Information about the structure of the track, the transmission antenna, etc. In some aspects, the third additional channel may be transmitted every four (four) super code frames, wherein the super code frame does not include a second additional channel for carrying the paging message. In other aspects, the second additional channel can carry the information about the reverse link frequency hopping pattern channel mapping, the transmission power, the power control parameters, the access parameters, etc., by providing the above information in the first and second additional channels, The system can dynamically configure the loop preamble, the number of antennas and the pilot structure, etc. This can support the flexible addition of the forward link and the reverse link control channel, which can match the current load. "The sample code in the super code box can use three capture instructions. In Chen 122119.doc -15 - 200812282, only two pilots, TDMl 316 and TDM2 318, are shown. In some aspects, TDM1 316 is a periodic PN sequence having four periods in which every fourth tone is filled in the frequency domain. In one aspect, each sector of an access terminal transmits the same sequence of TDM1 3 16 . In one aspect, TDM2 318 is agitated with a time domain sector dependent sequence. In some aspects, the time domain sequence can have a low peak-to-average ratio (PAR) and allow for an increase in power with respect to the traffic signal (as needed). In some cases, the sequence is selected as a Walsh sequence with pseudo-noise (PN) code. In some aspects, the walsh sequence is correlated at the receiver using a fast Hadamard code transform. In other aspects, 5 12 Walsh sequences are available for 5 12 different sector identifications to be utilized. In some aspects, one or more subcarriers of TDM2 3 18 can be used to carry an indication of interference from other sectors. For example, information indicating one or more bits of varying power by accessing the terminal can be utilized. In some aspects, the TDM1 316 and TDM2 318 can be used in the case of sector synchronization or substantially synchronous, or when the sectors are not synchronized. In the case of a synchronous or substantially synchronous system, the indicator can be changed from the hyperframe to the superframe. In addition, different sectors may use the same sequence of offsets to provide further improvements in the ability to discriminate between different sectors. In addition, this is not required for synchronization at the symbol/time gap level. In the aspect, in an asynchronous system, the indication can be the same from the super code frame to the super code frame, and there is no synchronization requirement between the sectors. A third indicator can be added to extend beyond the hyperframe preamble. It should be noted that the first additional channel, the second additional channel, and the subcarriers and symbol positions of the indications may vary from 122119.doc -16 - 200812282 and need not be exactly similar to that shown in FIG. In addition, although each of the except the first additional channel is shown to occupy the entire OFDM symbol, this need not be the case and less than all of the subcarriers may be utilized for a given OFDM symbol. Referring to Figure 4, an aspect of the channel structure of a multiple access wireless communication system is illustrated. Depending on the system design parameters, a bandwidth 400 which can be a virtual bandwidth having a plurality of discontinuous portions can be used for communication. The structure includes one or more forward link frames 404 and reverse link frames 408, each of which may be one or more of the ultra-macro pinches as discussed with respect to FIG. 2A and/or FIG. Part of it. Each forward link frame 404 includes a control channel 406. Each of the control channels 406 may include information regarding functions related to, for example, retrieval; acknowledgment; each access terminal is previously assigned to a link (for broadcast, multicast, and unicast message types, They may be different or identical), the reverse link assignment of each access terminal; reverse link power control for each access terminal; and reverse link acknowledgment. It should be noted that more or less of these functions can be supported in control channels 4〇6. And, depending on the hopping sequence that is the same or different from the hopping sequence assigned to the data channel, control channel 4 〇 6 can be frequency hopped in each frame. Each reverse link frame 408 includes a number of reverse link transmissions from the access terminal, e.g., 412, 414, and 416. In Figure 4, a reverse link transmission is depicted as a block, i.e., a set of adjacent 〇FDM symbols. It should be noted that symbol rate hopping can also be utilized, for example, non-adjacent symbol blocks. In addition, each reverse link frame 408 can include one or more reverse link control channels 440' that can include feedback channels; for reverse link channel evaluations 122119.doc -17-200812282 Channels, and acknowledgment channels that may be included in reverse link transmissions 412, 414, 々Η. Each of the reverse link control channels 440 may include information regarding functions related to the following functions, such as forward link and reverse link resource requests for each access terminal; channel information, for example, different types The channel quality information (CQI) of the transmission; and the indication from the access terminal that can be used by the access point for channel evaluation purposes. It should be noted that T in the L C 440 controls more or less of these functions. Also, the reverse link control channel 440 can hop in each frame based on the same or a different hopping sequence as the hopping sequence assigned to the data channel. " In some aspects, for multiplexed use on the reverse link control channel 44, the parent or user may be separated by - or multiple orthogonal codes, code sequences, or the like. Or different types of information transmitted in the reverse link control channel 44A. These orthogonal codes may be user specific or may be configured by the access point to each access terminal in each communication session or shorter period (e.g., per superframe). In addition, in some aspects, some of the available subcarriers in a 0FDM symbol may be represented as guard subcarriers and may be unmodulated, i.e., no energy is transmitted on the subcarriers. A number of guard subcarriers in the hyperframe preamble and in each frame may be provided via one or more of the control channel 4〇6 or the hyperframe preamble. In some aspects, to reduce additional transmissions to a particular terminal, the access terminal can collectively encode a packet even if the packets are to be transmitted on the secondary carrier. 0 .^ m ^ In this way, the early one-cycle redundant check can be used for the packet, and includes the white + Chu & a 祜 自 自 自 自 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 Check for additional transmissions. It should be noted that the bandwidth 400 can include discontinuous subcarriers and does not require proximity. In such aspects, the control channel may be limited to less than all of the W-portions of a carrier randomly placed in the portions, or may be scheduled in the portions in some deterministic manner. Referring to Figure 5A, an aspect of a forward link frame of a multiple access wireless communication system is illustrated. As shown in Figure 5A, each forward link frame 4〇4 is further divided into two segments. First, the subcarriers that may or may not contain an adjacent group have a variable number of subcarriers that are assigned depending on the amount of control data and other considerations. The remainder 422 is typically available for > material transfers. Control channel 406 can include one or more of pilot channels 5 12 and 514. In the symbol rate hopping mode, the pilot channel may be present on each of the OFDM symbols in each forward link frame and, in such cases, need not be included in control channel 406. In either case, signal transmission channel 516 and power control channel 518 can be present in control channel 〇6 (as depicted in Figure 5A). Signal transmission channel 516 may include assignments, acknowledgments, and/or V, . / power references and adjustments to data, control, and pilot transmissions on the reverse link. Power control channel 518 can carry information about interference generated at other sectors due to transmissions from the sector's access terminals. Also, in some aspects, subcarrier 420 at the edge of the entire bandwidth can be used as a quasi-protected subcarrier. It should be noted that in the case where multiple transmission antennas are available for transmission for a sector, different transmission antennas should have the same hyperframe timing (package 122119.doc • 19-200812282 including the super code frame index), OFDM symbol characteristics and hopping sequences. It should be noted that in some aspects, channels 5 12, 514, 516, 5 18 of control channel 406 may include the same configuration as data transfer, for example, for data transmission via block hopping, for control channel 406 , you can configure blocks of the same or different sizes. Referring to Figure 5B, an aspect of a reverse link frame of a multiple access wireless communication system is illustrated. The pilot channel 522 can include a pilot to allow the access point to evaluate the reverse link. Request channel 524 may include information to allow an access terminal to request resources that follow the reverse link and forward link, frame. The reverse link feedback channel 526 allows the access terminal to provide feedback regarding the channel information CQI. The CQI can be associated with one or more scheduled modes, or for scheduling, available modes for transmission to an access terminal. Exemplary modes may include beamforming, SDMA, precoding, or a combination thereof. The power control channel 528 can be used as a reference to allow the access point to generate power control commands for accessing the reverse link (e.g., data transmission) of the terminal. In some aspects, power control channel 528 can include one or more of feedback channels 526. Data channel 432 can operate according to a symbol rate hopping pattern or a block hopping pattern in different reverse link frames 4〇8. Also, the subcarrier 4 80 at the edge of the positive bandwidth in some of the samples may serve as a quasi-protected subcarrier. It should be noted that while Figures 5A and 5B depict the different channels that make up control channels 4〇6 and 44〇 as being multiplexed in time, this need not be the case.多 Use different positive parents, quasi-fathers or any combination of mixing codes, different frequencies or times, codes and frequencies to multiplex the different channels that make up the control channel 4〇6 and the *12122.doc 200812282. Referring to Fig. 6, a block diagram of an exemplary first communication device or system 81 and an exemplary second communication device or system 85 in a system 800 is illustrated. At the first communication device 810, a plurality of data streams are provided from the data source 812 to the transmission data processor 814. In one embodiment, each data stream is transmitted via a respective transmit antenna. The τ data processor 814 formats, encodes, and interleaves the traffic data for the data stream based on a particular coding scheme for each data stream to provide encoded data. OFDM techniques can be used to multiplex the encoded data for each data stream with the pilot data. The pilot data is typically a known data pattern that is processed in a known manner and that can be used at the receiver system to evaluate channel responses. The multiplexed indication of the data stream is then modulated (ie, symbol mapped) based on a particular modulation mechanism (eg, Bpsk, QSPK, M-PSK, or M-QAM) selected for the parent-stream. And encoded information to provide modulation symbols. The data transfer rate, encoding, and modulation of each data stream can be determined by instructions executed by processor 830. The modulation symbols for each of the data streams are then provided to a TX processor 820, which may further process the modulated symbols (e.g., for OFDM). Next, TX processor 820 provides Ντ modulated symbol streams to the transmitters (TMTR 822a through 822t). Each transmitter 822 receives and processes a respective symbol stream to provide one or more analog signals, and further conditions (e.g., amplifies, filters, and upconverts) the analog signals to provide a tone suitable for transmission over the helium channel. Change the signal. Next, Ντ modulated signals from transmitters 822a through 822t are transmitted from Ντ antennas 122119.doc -21 - 200812282 824a through 824t, respectively. At the second communication device 850, the transmitted modulated signals are received by the NR antennas 852a through 852r and the received signals from each antenna 852 are provided to a respective receiver (RCVR) 854. Each receiver 854 (854a through 854r) conditions (e.g., filters, amplifies, and downconverts) a respective received signal, digitizes the conditioned signal to provide samples, and further processes the samples to provide a corresponding " The received '' symbol stream. Next, an RX data processor 860 receives and processes the received symbol streams from the NR receivers 854 based on a particular receiver processing technique to provide Ντ" detected. The symbol stream. The processing of the RX data processor 860 is described in further detail below. Each detected symbol stream includes symbols for evaluation of the modulation symbols transmitted for the corresponding data stream. Next, the RX data processor 860 solves Modulating, deinterleaving and decoding each detected symbol stream to recover the data stream of the data stream. The recovered data is stored in the data slot 864. The processing of the RX data processor 860 is performed by the TX processor 820 and The TX data processor 814 is complementary to the processing performed at the first communication device 810. The RX data processor 860 can be limited to the number of subcarriers that can be simultaneously demodulated, for example, 512 subcarriers 5 MHz, 128 subcarriers or 1.25 MHz, 256 subcarriers or 2.5 MHz. Channel response evaluation generated by RX processor 860 can be used to perform spatial, spatial/time processing at the receiver, adjust power levels, change tone A variable rate or scheme, or other action. The RX processor 860 can further evaluate the signal-to-interference ratio (SNR) of the detected symbol stream, and possibly other channel characteristics 122119.doc -22-200812282 The amount is provided to the processor. The Rxf processor_or processor 870 can further derive the evaluation of the system, operation & SNR. Next, the processor 870 provides channel status information (CSI), which can include Communication type key and/or various types of information of the received data stream. For example, the CSI may include an operational SNR. Then, the CSI is processed by the *τχ data processor m, and is modulated by the modulator 880. , is transmitted by the transmitters 85 乜 85 and transmitted back to the first communication device 8 额外. Additional bedding from the data source 816 (eg, including reverse link traffic) may (and sometimes ) received by τχ资竹娜^王斋818; borrowed The modulator 88 is modulated; the transmitter 854 & to 8541* is adjusted and transmitted to the first communication device 810. At the first communication device 8 10, the modulated from the second communication device 85A The L number is received by the antenna 824, adjusted by the receiver 822, demodulated by the demodulator 840, and processed by the *RX data processor 842 to recover the CSI reported by the receiver system. The reported cSI is then provided to the processor 830, and is used to (1) determine the data transmission rate and coding and modulation scheme to be used for the data stream, and (2) generate the data processor 814 for the data processor 814 and The various controls of the processor 820. Alternatively, the CSI, along with other information, can be used by the processor 870 to determine a modulation scheme and/or coding rate for transmission. This can then be provided to the first communication δ and the transmitter using this information (which can be quantized) to provide a later transmission to the receiver of the second communication device. The data recovered by the RX data processor 842 can be (and sometimes is) stored in the data slot 844. The recovered data may (and sometimes does) include reverse link traffic data. Processors 830 and 870 direct operations at the first and second communication devices, respectively, 122119.doc -23-200812282. Memory 832 and 872 provide storage for the code and data used by processors 83 and 87, respectively. At the receiver, various processing techniques can be used to process the Nr received signals to detect the transmitted symbol streams. These receiver processing techniques can be grouped into two main categories: (1) spatial and spatial time receiver processing techniques: (also referred to as equalization techniques); and (ii) "continuous zero/equalization and interference cancellation" reception Processor processing techniques (also known as "continuous interference cancellation," or "continuous cancellation" 'receiver processing techniques. Although FIG. 6 depicts a one-shot system, the same system can be applied to a multiple input single output system in which multiple transmit antennas (eg, transmit antennas on a base station) stream one or more symbols to a single antenna device, such as , a mobile station). Also, a single output to a single input antenna system can be utilized in the same manner as described with respect to FIG. The transmission techniques described herein can be implemented by a variety of means. By way of example, such techniques can be implemented in hardware, bodily, soft, or a combination thereof.

For the case of a 128-point FFT, another exemplary hyper-coded preamble contains 32 〇FDm symbols. For the sake of simplicity, the description below is for FFT sizes of 512 and above. For other cases, compared with the case of 512 points, each component channel of the super code frame is scaled (time repeated) with appropriate coefficients (in the case of a 256-point FFT, the coefficient is 2, and in the case of a 128-point FFT, the coefficient is 4). The last three OFDM symbols (718, 720, 122119.doc - 25 - 200812282 722) in the hyperframe preamble 706 (symbol indices 5, 6, and 7) are TDM lures for initial capture. Such compliance may also be referred to as TDM introduction 1, TDM introduction 2, and TDM introduction 3. The first of these forms a capture channel (F-ACQCH), which is reused to transmit other sector interference channels (F-OSICH). The TDM pilot 1 is transmitted on OFDM symbol 7 (722), while the TDM pilot 2 and 3 are transmitted on OFDM symbols 5 and 6 (718, 720), respectively. An exemplary TDM introduction 1 will now be described. The TDM pilot 1 is an OFDM symbol containing a time domain PN sequence having four periods. The construction of the TDM pilot 1 depends on whether the bandwidth is less than 5 MHz or greater than 5 MHz. In deployments with a bandwidth of 5 MHz or less, this OFDM symbol is constructed by FFT using a PN sequence of length NFFT/4 and filling every fourth subcarrier with FFT values (excluding guard subcarriers). This is followed by an IFFT and adds a loop preamble and an open window time interval (as in each of the other OFDM symbols). The PN sequence used for this purpose does not depend on the sector, so it is not possible to identify the sector using TDM to indicate 1. However, the PN sequence does depend on the bandwidth. A different PN sequence is used for each of the following three cases: BWS1.25 MHz, 1.25 MHz < BWS 2.5 MHz and 2.5 MHz < BWS5 MHz. In a bandwidth greater than 5 MHz, the bandwidth is split into segments each having a bandwidth of 5 MHz. In any given super code frame, a sector transmits a TDM indicator 1 on a sector. However, the sector on which the sector transmits the indication changes from the hypercode frame to the hyperframe. Segments are selected differently in two different synchronization modes. The time domain sequence used for modulation is again independent of the sector and depends on the total bandwidth and index of the segments. 122119.doc -26- 200812282 TDM can be used to get the evaluation of the super-frame timing. For example, the AT can associate the received waveform with a known DM pN sequence and compare the correlation value to a threshold to determine if there is a TDM reference in any given time period. Once the timing is identified, the AT can proceed to sector identification using TDM and 2 and 3. The TDM indicator can also be used for frequency correction. Exemplary TDM primers 2 and 3 will now be described. TDM references 2 and 3 are used for sector identification after one or more strong paths have been retrieved using TDM. What is the use of TDM for 2 and 3 systems? >; Sequence agitation One of the time series sequences of one of the 1〇24 sequences is constructed. The 512 elements at the beginning of the Walsh sequence are used to construct the TDM Representation 2, and the subsequent 512 elements are used to construct the TDM Representation 3. The Walsh sequence depends on the pil〇tpN of the sector and does not change from the hyperframe to the hyperframe. Of the 1024 sequences, 512 sequences are reserved for the semi-synchronous mode, and the other 5 12 sequences are reserved for the asynchronous mode. In the case of a deployment with a bandwidth of 3 MHz, the PN sequence depends on the system frequency, and in the case of a bandwidth > 5 MHz deployment, the PN sequence depends on the system bandwidth and the sector index. The section on which the TDM pilot 2 and 3 are transmitted is the same as the section on which the TDM pilot 1 is transmitted. The sync mode will now be described. The system supports two modes, semi-synchronous and non-synchronous, and in both cases, TDM citations are generated differently. The semi-synchronous mode will now be described. For some applications, such as ranging, it is used to detect very weak sectors. For this reason, it may be important to allow correlation on more than one superframe preamble. Advantageously, the interference signal (i.e., the TDM indication of the adjacent 122119.doc -27-200812282 sector) is changed from a super code frame preamble to the next super in order to obtain processing gains on more than one super code frame preamble. Code box preamble. To enable this, an auxiliary amount (called PilotPhase) from the hyper-frame to the super-frame change is defined for each sector. Pil〇tphase is a 9-bit quantity as defined by Pil〇tPhase=(Pil〇tPN+SUperframeIndex) m〇d 512, where Superframelndex is a counter that is added from one super code frame to the next, and is in the sector Everyone is defined globally. call. The muscle coffee is used to generate two TDM primer sequences. In addition, the section on which the TDM is transmitted in the deployment with Bw > 5 MHz is pseudo-randomly selected as the function of PilotPhase. When the different sectors use the same sequence offset, the pilot structure has Synchronization of some levels between two sectors. For the sake of brevity, if all possible values of pii〇tpN are possible, then this structure requires that any two sectors be synchronized within one half of a super code frame - but not at the symbol or time gap level. Otherwise, it is conceivable that two sectors with different PilotPNs can transmit the same capture (same PN sequence) at the same time. This mode can be (and sometimes is) used to improve performance (reduces acquisition time, fast sector switching, interference assessment, etc.). The asynchronous mode will now be described. In some cases, it is not possible to accurately synchronize two sectors. In order to support these situations, there is a mode in the system that does not have synchronization requirements. In this mode, pilot PN is used to directly agitate the TDM primer instead of the auxiliary PilotPhase. For systems with a bandwidth "MHz", the TDM pilot is the same from the superframe to the superframe. For systems with bandwidth > 5 MHz, the TDM pilot deterministically passes the set of available zones. Paragraph loops. 122119.doc -28- 200812282 An exemplary capture procedure will now be described. The five OFDM symbols (708, 710, 712, 714, 716) at the beginning of the hypercode preamble are used to carry two main Broadcast channels, namely F_pBCH0 and F_PBCH1. The first 0FDM symbol 7〇8 includes an F-pBCHO portion 724 and an F-pBCH1 portion 726. The second to fifth OFDM symbols (708, 710, 712, 714, 716) carry F_pBCH^ These channels carry configuration information that the AT needs to have before it can demodulate the PHY frame. In addition, the F-pBCH1 channel also carries paging information. In this exemplary embodiment, encoding on 16 super-code blocks An F_pBcH packet, which occupies the smallest 〇FDM. in each supercode preamble. In addition to the hyperframe index, p_pbcho carries a wide range of static parameters (such as loop preambles). Duration, number of protection subcarriers), and only during initial wakeup It is required to encode an F_pBCH1 packet on a single super code frame, and it occupies the 43⁄4 0FDM symbol in each super code frame preamble. The bandwidth of this channel is approximated by about 2%. F-PBCH1 carries enough information to make Ατ It can demodulate FL data from ρΗγ frame (such as information about FL frequency hopping pattern, lead structure, control channel structure, transmission antenna, etc.). This information is transmitted in each alternate super code frame; other super code frames are used. To carry a page, for example, a quick page. Use a regular data channel in a predefined hypercode frame to broadcast the remaining additional information. This carries information about the RL hopping pattern, channel mapping, transmission power, power control parameters, access parameters, etc. Information. These channels enable a flexible physical layer that allows for flexible configurations of the loop preamble, the number of antennas, the lead structure, etc. It also supports flexible add-on FL and RL control channels that match the current 122119.doc -29- 200812282 user load and can be enabled or de-featured as sub-band scheduling, FFR, etc. At initial wake-up, AT First use TDM to detect a sector and achieve time and frequency synchronization. In semi-synchronous mode, Ατ knows the value of the Pilotphase variable at the end of this phase, while in the non-synchronous mode, the octopus knows to end at this stage. The value of the PilotPN variable at that time. Then, at continues to demodulate the F-pBCH0 and F-pBCH1 channels. In the semi-synchronous case (PilotPN=Pil〇tPhase · Superframelndex mod 512), the F·pBCHO channel is lower. 9-bit, which enables eight to find the value of PilotPN. Therefore, in the semi-synchronous and non-synchronous modes, at the end of this phase, the AT knows the PilotPN and Superframeindex variables, which together are used to inoculate the various random number generators used in generating the FL waveform (for frequency hopping, agitation, etc.) . In one embodiment, the other sector interference channel (F-0SICH) carries a three-state quantity that is modulated into one of the phases on TDM indicators 2 and 3. Since the TDM pilot waveform is known once the capture is completed, the superposition does not cause degradation of the effect of qwch. One of the features is that it is used by Ατ in the adjacent sector, that is, it should be decodable at very low SNR. This is accomplished by providing a very large propagation gain for this channel (i.e., an entire OFDM symbol for transmitting less than two bits of information or two OFDM symbols for transmitting less than two bits of information). 8 is a flow chart diagram 9.1 of an exemplary method of operating a communication device (e.g., an access point or a base station) in accordance with various embodiments.
