Abstract

The present invention describes systems and methodologies that facilitate signal acquisition in a wireless communication system on one or more frequency carriers corresponding to a portion of the deployed bandwidth in a wireless communication environment. By communicating using carriers that include only a portion of the total system bandwidth, channels used for communication in a carrier may be less dispersive than channels used for communication across the entire bandwidth. Thus, the amount of transmit power required for devices in the system may be reduced. Further, the carriers may be divided from the deployed system bandwidth such that each carrier is sufficiently large to minimize the effects of fading on component frequency response, thereby further optimizing system performance.

[0048] Fig. 2 is the block diagram of system 200 that is used for being convenient to the signals collecting of wireless communications environment according to various aspects as herein described.In an example, system 200 comprises access point 210 and a plurality ofly accesses terminal 220.Though for the sake of brevity and not shown in the system 200, system 200 can also comprise a plurality of access points 210.According to an aspect, access point 210 can comprise one or more antenna groups 212, wherein each antenna group can comprise one or more can with one or more 220 antennas of communicating by letter 214 and/or 216 of accessing terminal.For example, as shown in system 200, antenna groups 212 1Comprise R antenna 214 and antenna groups 212 NComprise T antenna 216.In an example, access point 210 can Serving cell (for example, sub-district 102), and the sector (for example, sector 104) of each antenna group 212 in the access point 210 in can Serving cell.
[0049], the bandwidth that can be used for the communication in the system 200 can be divided into a plurality of carrier waves according to another aspect.Then, each antenna group 212 in each access point 210 and/or the access point 210 can use one or more carrier waves 220 to communicate by letter with accessing terminal.This communication can comprise, for example, one or more collection pilot tones and/or broadcast channel sent to access terminal 220.Can use each carrier wave at each access point 210 place, perhaps replacedly, each access point 210 can use the subclass of available carrier wave.Similarly, each antenna group 212 in the access point 210 can use all carrier waves that access point 210 provided or the subclass of these carrier waves.The carrier wave that uses in system 200 can be unique to the antenna groups 212 in each access point 210 and/or the access point 210, and perhaps replacedly, a plurality of access points 210 and/or antenna groups 212 can use particular carrier wave.
[0050] according to further aspect, one or more accessing terminal 220 can be via the antenna 222 of correspondence, is received in each antenna 214 and 216 acquired signal that sent in the access point 210, broadcast channel and/or other is communicated by letter.220 places only show an antenna 222 though each accesses terminal, and recognize each 220 antenna 222 that can have any amount that access terminal.In addition, access terminal each antenna 222 at 220 places can be used for the antenna groups 212 of one or more access points 210, access point 210 with and/or other access terminal and 220 communicate by letter.In an example, each accesses terminal and 220 can be on system's 200 employed carrier waves receives acquired signal from access point 210.220 carrier waves that are used for receiving acquired signal that access terminal can be scheduled to, and perhaps replacedly, one or more accessing terminal 220 can monitor acquired signal on the entire available bandwidth of system 200.
[0051] in another example, each accesses terminal and 220 can receive the distribution that is used for one or more carrier waves of communicating by letter with the antenna groups 212 of access point 210 or access point 210.Lift non-limiting instance, can distribute, so that can 220 distribute to single carrier wave, can 220 distribute to a plurality of carrier waves with having accessing terminal of the bigger ability of on broadband more, communicating by letter simultaneously with having accessing terminal of the limited capability of on broadband, communicating by letter.According to an aspect, this distribution can comprise by each 220 carrier wave and/or one or more other carrier wave that are used for receiving acquired signal that access terminal.In addition, simultaneously one or more accessing terminal 220 can be used each carrier wave simultaneously.For example, shown in 200 of systems, can will access terminal 220 K-1Distribute to carrier wave N, and can will access terminal 220 KDistribute to carrier wave N and distribute to the second carrier wave N+R extraly.
[0052], than communicating by letter on the littler carrier wave of the total bandwidth of system 200, can reduce the influence of the channel dispersion in the system 200 by on the whole according to an aspect.Thereby this can reduce each access point 210 and/or the 220 needed transmitted powers that access terminal, thus improve each access point 210 efficient and/or save each battery life of 220 of accessing terminal.In addition, can divide system bandwidth, so that big must being enough to of each carrier wave minimizes the influence of other the similar factor on decline and the systematic function.With regard to concrete, unrestriced example, system 200 can use the 20MHz bandwidth, and each carrier wave can comprise the 5MHz of overall bandwidth.Yet, recognize that this example only shows system bandwidth and the possible division of carrier wave that can adopt in system 200, and can adopt other suitable system bandwidth and/or carrier wave division arbitrarily.
[0053] Fig. 3 A shows the example super-frame structure 302 of the multi-address radio communication system (for example, system 100) that is used to use Frequency Division Duplexing (FDD) (FDD).In an example, in the initial transmission super-frame preamble 312 of each superframe 310.Super-frame preamble 312 can be crossed over the part of a carrier wave or a carrier wave.In addition, for the superframe 310 of each superframe 310, predetermined quantity, fixing duration or another suitable interval, each super-frame preamble 312 can saltus step.In addition, each super-frame preamble 312 can be according to hopping sequences or form and saltus step can be determined this hopping sequences or form based on the identification of access point (for example, access point 110).For example, access point identification can be pseudo noise (PN) sequence, and wherein access terminal (for example, terminal 120) can determine the saltus step form or the sequence of superframe 310 from this pseudo noise (PN) sequence.Then, access terminal and to determine the carrier wave that is associated with super-frame preamble 312 in the next superframe 310 based on access point identification and the carrier wave that is associated with super-frame preamble 312 in last superframe 310.In addition,, recognize that superframe 310 can replacedly be the reverse link superframe though superframe 310 is depicted as forward link (FL) superframe.
[0054] in an example, transmission can be divided into the unit of superframe 310, each unit reaches the series of frames of closelying follow thereafter 314 by super-frame preamble 312 and is formed.In FDD structure 302, rl transmission can take different frequencies with forward link transmissions, so that being transmitted on the given arbitrarily frequency sub-carrier on forward direction and the reverse link is not overlapping substantially.In another example, super-frame preamble 312 can comprise pilot channel, and pilot channel can comprise the pilot tone that is used for channel estimating by accessing terminal.In addition, super-frame preamble 312 can comprise broadcast channel, and broadcast channel comprises that can be used for being used for demodulation by access terminal (for example, terminal 120) is included in the configuration information of the information in the forward link frame 314.In addition and/or replacedly, super-frame preamble 312 can comprise Information Monitoring, for example regularly and other be enough to make access terminal information, the power control information of communication and/or offset information.Therefore, super-frame preamble 312 can comprise one or more shared pilot channels, broadcast channel, collection pilot channel, other sector interference channel and/or other suitable channel.
[0055] in another example, super-frame preamble 312 can comprise and being used for synchronously and pilot channel that sector ID is gathered, carry first broadcast channel of static deployment parameters and system timing, and/or carry second broadcast channel of quasistatic sector parameters.In an example, the entrained quasistatic sector parameters of second broadcast channel can be relevant with the quick paging channel in the even superframe 310 with the forward link configuration in the strange superframe 310.In addition, parameter can comprise auxiliary dynamic parameter, for example sector load.In another example, first broadcast channel can be coded on a plurality of superframes 310 and with second broadcast channel and be coded on the single superframe 310.
[0056] according to an aspect, super-frame preamble 312 can comprise one or more symbols, one or more symbols in for example OFDM symbol, and super-frame preamble 312 can be according to the hopping sequences of coordinating between sector (for example, the sector 104) or form and saltus step.For example, can use by the set of the sector of network or all sectors shared hopping sequences or scheduling scheme.According to another aspect, first broadcast channel, second broadcast channel or the first and second broadcast channel boths can saltus steps in given superframe 310.
[0057] in another example, the total bandwidth that is used for system can be divided into one or more carrier waves, thereby and each carrier wave can be divided into a plurality of frequency sub-carrier or tone.Then, at each superframe 310 at place, each sector, can use one of them carrier wave to increase super-frame preamble 312 corresponding to each superframe 310 separately.In addition, will be applied to the tone that constitutes super-frame preamble 312 with factor K more subsequently.Therefore, the given superframe 310 (this paper is designated as SFidx) that given sector (this paper is designated as Pilot PN) located, can with broadcast channel, other channel and/or have index k (symbol definition of the super-frame preamble 312 of the superframe that carrier wave provided 310 of 0≤k≤K) is as follows:
K=pilot phase mod K;
Pilot phase=(the mod N of Pilot PN+SFidx); (1)
Wherein, Pilot PN and pilot phase can be at the sign scrambling index of given sector or be used to discern another suitable factor of given sector, and N is corresponding to the predetermined maximum value of pilot phase.In an example, can use Pilot PN and pilot phase to come in the scrambling super-frame preamble 312, to allow the discerning sector by accessing terminal by one or more pilot signals that given sector sent.
[0058],, then can in super-frame preamble 312, not carry out paging if the frequency spectrum shared of super-frame preamble 312 is used in a plurality of sector according to another aspect.For example, if the subcarrier that comprises super-frame preamble 312 is shared in a plurality of sector, then can not carry out paging.In addition, be under the situation of identification separately of different sector in Pilot PN 1 and Pilot PN 2, can to keep saltus step be quadrature by obeying following equation:
(Pilot PN 1-Pilot PN 2) mod K ≠ 0.(2)
Therefore, different sector in the system for example, has the sector of different Pilot PN mod K values, will use different carrier waves.Lift concrete, unrestriced example, then, based on mode (1), this system can reach the frequency reuse of 7 sectors by selecting to be divided into eight subclass with factor K=8 and with the available system bandwidth again.Then, can coordinate frequency the planning of planning and Pilot PN index so that do not distribute the subclass of the bandwidth that satisfies Pilot PN mod 7=0, and carry out the frequency reuse plan of 7 sectors with all the other 7 subclass.In interchangeable unrestricted example,, can use factor K=7 again by selection, and the available system bandwidth is divided into seven frequency reuses that subsequently subclass that is assigned with realized 7 sectors according to equation (1).In this example, the value corresponding to the peaked N of pilot phase can be chosen as 7 multiple.In concrete, a unrestriced example, can elect N as 511.
[0059] in addition, series of frames 314 can be immediately following after super-frame preamble 312.Each frame 314 can be made up of OFDM symbol unified or skimble-scamble quantity and the subcarrier that can be used to simultaneously transmit unified or skimble-scamble quantity.Lift concrete, unrestriced example, super-frame preamble 312 can be made up of 32 OFDM symbols, and closelys follow 48 frames 314 after the super-frame preamble 312, and wherein each frame 314 is made up of 8 OFDM symbols.In interchangeable unrestriced example, each super-frame preamble 312 can be made up of 16 frames, and closelys follow 48 frames 314 that length is 8 OFDM symbols after the super-frame preamble 312.In addition, each frame 314 can be operated according to symbol rate saltus step mode 3 22, wherein one or more discontinuous OFDM allocation of symbols is given the terminal on forward link or the reverse link.Replacedly, each frame 314 can be operated according to piece saltus step mode 3 20, and wherein terminal can saltus step in the piece of OFDM symbol.At piece saltus step mode 3 20 and symbol rate saltus step mode 3 22 among both, piece or OFDM symbol can saltus steps between frame 314 or can not saltus steps.
[0060] according to another aspect, superframe 310 can not use super-frame preamble 312.In an interchangeable example, lead code can possess one or more frames 314, and frame 314 comprises the information with super-frame preamble 312 equivalences.In another interchangeable example, can use Broadcast Control Channel to comprise the some or all of information of super-frame preamble 312.In the control channel of lead code or frame 314, can comprise out of Memory extraly.
[0061] Fig. 3 B shows the example super-frame structure 304 of the multi-address radio communication system that uses time division duplex (TDD).In an example, can be in the initial transmission super-frame preamble 312 of each superframe 310, wherein the structure and the performance of the super-frame preamble 312 in the structure of super-frame preamble 312 and performance and the FDD structure 302 are basic identical.According to an aspect, can be after each super-frame preamble 312 in the TDD structure 304 immediately following a series of forward link frames 314 and reverse link frame 316 are arranged.Can be according to time divide forward isl frame 314 and reverse link frame 316, make the transmission of the forward link frame 314 of predetermined quantity continuously before the transmission of the reverse link frame 316 that allows predetermined quantity.Shown in institute in the superframe structure 304, forward link superframe 310 will experience the silence period between the transmission period of one or more reverse link frames 316.Similarly, recognize that reverse link frame will experience the silence period between the transmission period of forward link frame 314.In addition, recognize, in superframe structure 304, can send the forward link frame 314 of any amount and the reverse link frame 316 of any amount continuously, and can change in the quantity of described frame among the given superframe or between a plurality of superframes.
[0062] in addition, each forward link frame 314 can be made up of the unified or OFDM symbol of disunity quantity and the subcarrier of unification or disunity quantity, wherein similarly, this subcarrier can be used for transmission with the mode of the frame 314 in the similar FDD structure 302.In an example, each forward link frame 314 can be operated according to symbol rate saltus step mode 3 22, one or more discontinuous OFDM allocation of symbols is given the terminal on forward link or the reverse link in symbol rate saltus step mode 3 22.Replacedly, each forward link frame 314 can be operated according to piece saltus step mode 3 20, and terminal can saltus step in the piece of OFDM symbol in piece saltus step mode 3 20.At piece saltus step mode 3 20 and symbol rate saltus step mode 3 22 among both, piece or OFDM symbol can saltus steps between forward link frame 314 or can not saltus steps.
[0063] according to an aspect, superframe 310 can not use super-frame preamble 312.In an interchangeable example, lead code can possess one or more frames 314, and frame 314 comprises the information with super-frame preamble 312 equivalences.In another interchangeable example, can use Broadcast Control Channel to comprise some or all information of super-frame preamble 312.In the control channel of lead code or frame 314, can comprise out of Memory extraly.
[0064] Fig. 4 is the exemplary channel structure of the multi-address radio communication system (for example, system 100) according to various aspects.In an example, according to system design parameters, bandwidth 400 can be used for communication.In addition, bandwidth 400 can comprise a plurality of carrier waves 402.Each carrier wave 402 can comprise one or more forward link frames 404 and reverse link frame 408, and forward link frame 404 and reverse link frame 408 all are the parts of one or more superframes (for example, superframe 310).
[0065] according to an aspect, each forward link frame 404 of each carrier wave 402 can comprise one or more control channels 406.For example, each control channel 406 can comprise: the information that is used to relate to the function of collection; Confirm; In the system each access terminal () forward link assignment for example, terminal 120, for broadcasting, multicast and unicast messages type, this distribution can be same or different; The reverse link assignment that in the system each accesses terminal; The power of reverse link control that in the system each accesses terminal; Reverse link is confirmed; And/or other suitable function.Recognize, the control channel 406 in each carrier wave 402 can provide unified or skimble-scamble information to support same or different function.In addition, according to unified between carrier wave 402 or skimble-scamble hopping sequences, control channel 406 can saltus step in each forward link frame 404.In addition, in each forward link frame 404 separately, the hopping sequences of each control channel 406 can be identical with the hopping sequences of distributing to the data channel (not shown) or different.
[0066] according to another aspect, each reverse link frame 408 can comprise a plurality of from the rl transmission 412-430 that accesses terminal.Though each the rl transmission 412-430 in the reverse link frame 408 is described as piece, the group of for example continuous OFDM symbol, but, recognize, each transmission 412-430 can replacedly use the symbol rate saltus step, and each transmission 412-430 can corresponding discontinuous symbolic blocks in the symbol rate saltus step.In addition, each reverse link frame 408 can also comprise a The function of backward power control channel 440.For example, The function of backward power control channel 440 can comprise feedback channel, be used for the pilot channel of reverse link channel estimation, can be included in the affirmation channel of rl transmission 412-430, and/or other suitable channel.In addition, each The function of backward power control channel 440 can be provided for, for example, forward link that in the system each accesses terminal and reverse link resources request, channel information are (for example, the channel quality information of different transport-types (CQI)), from (for example can be used for of accessing terminal by access point, the information of the pilot tone function associated of the purpose of channel estimating base station 110), and/or be used for the information of other suitable function.In an example, according to being unified or skimble-scamble hopping sequences between carrier wave 402, The function of backward power control channel 440 can saltus step in each reverse link frame 408.In addition, in each reverse link frame 408 separately, the hopping sequences that is used for each The function of backward power control channel 440 can be identical with the hopping sequences of distributing to the data channel (not shown) or different.
[0067] according to an aspect, on The function of backward power control channel 440, can use one or more orthogonal codes, scramble sequence or similarly code and/or sequence come the user is carried out multiplexing, thereby separate each user and/or the information of each unique type of in The function of backward power control channel 440, sending.In an example, orthogonal code is distinctive to the user.In addition and/or replacedly, access point can access terminal each of each communication session of orthogonal code division dispensing or shorter cycle (for example, each superframe 310).
[0068] in an example, some are accessed terminal distribute to single carrier wave 402, be assigned to same carrier wave so that on a plurality of frames of superframe or superframe, send to each forward link transmissions of terminal.Therefore, only can only need to monitor subclass accessing terminal of arbitrarily given time demodulation part bandwidth corresponding to the bandwidth 400 of a carrier wave 402.Replacedly, can distribute to carrier wave 402 with accessing terminal less than any amount of the whole carrier waves 402 in the bandwidth.In an example, by guaranteeing that forward link control channel 406 and repercussion controlling links channel 440 comprise the enough information that is used for each carrier wave 402, can support single carrier transmission, make the control channel 406 and 440 of carrier wave can be supported in accessing terminal of operating on the given carrier wave 402, and need not be with reference to the information that is included in other carrier wave.Can pass through, for example, the channel information of equivalence is included in the forward link control channel 406 of each carrier wave 402 and the The function of backward power control channel 440 provides needed support.Therefore, according to an aspect, in each carrier wave 402, can there be one or more collections, distribution, access, request, power control, pilot tone and reporting channel.These channels can be provided in, and for example, in the super-frame preamble (for example, super-frame preamble 312), and can be included in the forward link control channel 406 and/or The function of backward power control channel 440 of carrier wave 402.Yet, recognize, though each carrier wave can provide above-mentioned channel, actual coding, transfer rate, type of message and timing, resource allocation, Overhead Message transmission, saltus step form and/or sequence, and other transmission can change at different carrier wave 402 with location parameter.In addition, can not come form, transfer rate and/or saltus step information are sent signal via the control channel that separates that is not associated with concrete carrier wave 402 and/or other means, perhaps accessing terminal can be via not obtaining form, transfer rate and/or saltus step information with the control channel that separates and/or other means that concrete carrier wave 402 is associated.
[0069] in another example, on can be in a superframe two or the more carrier wave 402, in the continuous superframe, perhaps during communication session, scheduling has one or more terminals of the ability of stronger restituted signal.In addition, during communication session or superframe, these terminals can be used different carrier waves 402 with forward link frame 404 to reverse link frame 408.On can also the different carrier wave 402 in different superframes, perhaps these terminals of scheduling during communication session.In addition and/or replacedly, can with different carrier wave 402 this terminal of scheduling on the frame of basic synchronization in time.Can also dispatch this multi-carrier terminal,, and in whole overall bandwidth 400, provide the spatial multiplexing gain of statistics so that provide the load balancing of resource to given carrier wave 402.
[0070] for the multicarrier that is supported in operation on a plurality of carrier waves 402 accesses terminal, can use a plurality of methods.In first example, multicarrier accesses terminal and can demodulation be respectively applied for the super-frame preamble and the forward link control channel 406 of each carrier wave 402 of operating each terminal individually.Therefore, can carry out all distribution, scheduling, power control and other suitable operation based on carrier wave one by one.In second example, the control channel that separates can comprise the operating parameter of each carrier wave 402, thereby allow to access terminal the information of obtaining about the forward link control channel 406 of super-frame preamble and one or more carrier wave 402, wherein terminal via the control channel that separates at one or more carrier wave 402 enterprising line operates.In addition, extra control channel can also comprise and is used for demodulation and the information of one or more super-frame preamble of one or more carrier waves 402 of decoding, forward link control channel 406 and The function of backward power control channel 440.Therefore, terminal can also be decoded to super-frame preamble, forward link control channel 406 and/or the The function of backward power control channel 440 of given carrier wave 402 at any time.
[0071] in the 3rd example, can in super-frame preamble, forward link control channel 406 and/or the The function of backward power control channel 440 of single carrier wave 402, keep the group's of all carrier waves 402 or carrier wave 402 information.In this example, can in communication session, use the accessing terminal of a plurality of carrier waves can be, and can in same carrier wave or different carrier wave, send control information from single carrier wave receiving control information.According to an aspect, according to predetermined sequence or some other means, the carrier wave that is used for this function can change in time.In the 4th example, for a distribution of dispatching purpose can be formed a plurality of distribution from different carrier wave 402.Therefore, accessing terminal to receive distribution individually on a plurality of carrier waves 402, these are distributed to merge then, with determine in time with forward direction and reverse link can be overlapping or the complete distribution of nonoverlapping frame.
[0072] in concrete, unrestriced example, bandwidth 400 can be 20MHz, and each carrier wave 402 can comprise the bandwidth 400 of 5MHz.In addition, each carrier wave 402 can comprise 512 subcarriers.Yet, recognize, can use the subcarrier of the carrier wave 402 of other big or small bandwidth 400, other big or small carrier wave 402 and/or other quantity.For example, carrier wave 402 can comprise bandwidth and 128 subcarriers of 1.25MHz.Interchangeable, carrier wave 402 can also comprise bandwidth and 256 subcarriers of 2.5MHz.In addition, between carrier wave 402, the quantity of the subcarrier of distribution can change.The available bandwidth that the size of carrier wave 402 also is limited by from the entity of the available adjustment in the system distributes and division.In addition, recognize that one or more carrier waves 402 can be asynchronous each other, so that one or more carrier wave 402 can have different beginnings and/or concluding time to forward link frame 404 and/or reverse link frame 408.In this case, control channel 406 and/or signaling that super-frame preamble provided or the assignment messages timing information that can transmit carrier wave 402.
[0073] according to an aspect, the one or more available subcarriers in the OFDM symbol in the carrier wave 402 can be designated as protection subcarrier and not modulated, and making does not have power transfer on the subcarrier of appointment.In an example, can provide in the super-frame preamble via the one or more message in forward link control channel 406 and/or the super-frame preamble and the quantity of the protection subcarrier of the appointment in each superframe.According to another aspect, can be to access terminal combined coding grouping of multicarrier, so that reduce to the overhead transmission of terminal.For example, even when on the subcarrier of different carrier wave 402, sending the symbol of grouping, also can so do.Like this, can use single cyclic redundancy check (CRC), so that comprise the overhead transmission that is not limited by cyclic redundancy check (CRC) from the transmission on the carrier wave 402 of the symbol of described grouping at some to one or more groupings.Replacedly, comprise in the given grouping that by the symbol that only will on given carrier wave 402, send access point can be based on its grouping of each carrier modulation.In an example, access point can further make up some carrier wave 402 for the purpose of dividing into groups to modulate.For example, access point can be modulated to the symbol from preceding two carrier waves 402 in the single carrier wave together.
[0074] in addition, recognize that the scheduler that is used for each carrier wave 402 can use unified or skimble-scamble method is come saltus step.For example, different channel trees or saltus step conversion can be used for each carrier wave 402.In addition, can dispatch each carrier wave 402 according to unified or skimble-scamble technology and algorithm.For example, each carrier wave 402 can comprise as common unsettled U.S. Provisional Patent Application sequence number 11/261 that submit to, that be entitled as " SDMARESOURCE MANAGEMENT " on October 27th, 2005,837 described channel trees and structures are here with its complete being incorporated herein by reference.

[0088], shows the method 900 that is used in wireless communication system (for example, system 200), transmitting one or more carrier waves (for example, carrier wave 402) with reference now to Fig. 9.Can pass through, for example, terminal (for example, accessing terminal 220) is come manner of execution 900.Method 900 is 902 beginnings at the square frame place, go up the Information Monitoring of search from access point (for example, access point 210) in available system bandwidth (for example, bandwidth 400) in square frame place 902.Replacedly, can receive Information Monitoring from the antenna groups in the access point (for example, antenna groups 212).In an example, can on all available system bandwidth, carry out the search at square frame 902 places.Replacedly, carry out the search at square frame 902 places on can the one or more predetermined carrier wave in system bandwidth.
[0089] then, method 900 advances to square frame 904, wherein is identified for the carrier wave of one or more distribution of communicating by letter with access point and/or antenna groups at least in part based on the Information Monitoring that receives.In an example, the search of carrying out at square frame 902 places causes receiving Information Monitoring.In addition, the Information Monitoring of reception can be to receive on the single carrier wave in system bandwidth.In this example, the one or more carrier waves that distribute at square frame 904 places can comprise or can not comprise the carrier wave that is used to receive collection.In case finished the action that square frame 904 places are described, method 900 finishes at square frame 906 places, the one or more carrier waves that use square frame 904 places to distribute in square frame 906 are communicated by letter with access point.
[0090] Figure 10 shows the method 1000 that is used for gathering the information that is used to communicate by letter in wireless communication system (for example, system 200).Can pass through, for example, terminal is come manner of execution 1000.Method 1000 begins at square frame 1002 places, in square frame 1002, attempt the whole of available system bandwidth or basically all in the detection acquired signal.In an example, base station and/or antenna groups can send the part of acquired signal as super-frame preamble (for example, super-frame preamble 312).In addition, acquired signal can be crossed over all or be owned (for example, all except protection subcarrier 520 and/or 540) carrier waves substantially.In case detect acquired signal, method 1000 advances to square frame 1002, and carrier wave is determined in the position based on the subcarrier that receives acquired signal in square frame 1002.Then, method 1000 is advanced further to square frame 1006, determines the position of the super-frame preamble of upcoming frame (for example, frame 314) in square frame 1006 based on hopping sequences.In an example, can determine hopping sequences based on identification of base stations included in the detected acquired signal in square frame 1002 places.
[0091] then, method 1000 may be advanced to square frame 1008, transmits the request of access based on the definite super-frame preamble of carrier wave of determining in square frame 1004 places and/or square frame 1006 places in square frame 1008.In an example, corresponding to whether can on a plurality of carrier waves, communicating (for example) simultaneously, can modulate the request of access with sign indicating number quadrature or scrambling by terminal manner of execution 1000.Sign indicating number quadrature or scrambling can be equipped with or receive by signal the Information Monitoring that detects in square frame 1002 places in advance.
[0092] in response to the access request of transmitting at square frame 1008 places, can receive access permission message at square frame 1010 places, wherein confirm to insert request and/or distribute initial reverse link subcarrier or block of sub-carriers at square frame 1010.In an example, the access permission that receives at square frame 1010 places can comprise regularly to be adjusted, and this is regularly adjusted can be so that one or more rl transmission of access point (for example, the transmission at square frame 1012 and/or 1018 places) and reverse link calibration regularly.The original allocation that receives in square frame 1010 places can also comprise and in symbol rate saltus step pattern (for example being used for, symbol rate saltus step mode 3 22) or piece saltus step pattern (for example, piece saltus step mode 3 20) instruction of operation in, be used for the distribution of one or more subcarriers of communicating by letter of forward link and reverse link, and/or other timing and scheduling parameter.In case 1010 places have received access permission message at square frame, then the entity of manner of execution 1000 will be communicated by letter at square frame 1012 places according to first distribution that receives in square frame 1010 places.
[0093] then, can distribute one or more additional distribution at square frame 1014 places.Recognize that the action that square frame 1014 places are described is optionally, and does not need associated methods 1000 to carry out.Therefore, method 1000 can advance to square frame 1016 after square frame 1012 or 1014, receives second of reverse-link sub-carrier and distribute in square frame 1016.In an example, if determine and can communicate on a plurality of carrier waves simultaneously at square frame 1016, second distribution that then receives in square frame 1016 places can comprise the change carrier message, and can discern next or the adaptable carrier wave of current distribution.Replacedly, can be independent of second distributing and/or the distribution that replenishes arbitrarily that square frame 1014 places receive of in square frame 1016, being received, perhaps before them, send and change carrier message.In addition, can send on the forward link changing carrier message as one or more packets.Then, can confirm packet, with the change carrier message of having indicated demodulation by the entity that is used for manner of execution 1000.In another interchangeable example, the access permission that receives in square frame 1000 places can comprise the change carrier message.If insert each carrier wave individually, then can perhaps provide information one by one based on information initially is provided carrier wave.
[0094] according to an aspect, second distribution that receives in square frame 1016 places can comprise a plurality of distribution on the different carrier wave that can independently be decoded.Replacedly, second distributes the distribution of uniting can comprise a plurality of carrier wave of receiving via single carrier wave.According to another aspect, about regularly and the information of other attribute of carrier wave can possess second and distribute so that the operation of improvement on the carrier wave of up-to-date scheduling.If use one or more packets to come to signal to changing carrier message, then packet can comprise some parameter of the carrier wave that is used for up-to-date scheduling, thereby allows extra resource to be provided for the information of the suitable communication on the new carrier wave.Replacedly, each carrier wave (for example can be included in one or more super-frame preamble or control channel, control channel 406 and/or 440) is used to allow the communication on other carrier wave in, be used to allow modulate information and other appropriate information of the control channel of super-frame preamble and/or other carrier wave.In addition, can receive the independent message that (for example, via the control channel 406 and/or 440 that is used for carrier wave) comprised the parameter that is used for new carrier wave.Distribute in case receive second at square frame 1016 places, then method 1000 finishes at square frame 1018 places, wherein distributes according to second and finishes communication.In an example, when demodulation correctly during corresponding to the Information Monitoring of the carrier wave that distributes (for example) at square frame 1004 places, be used for manner of execution 1000 entity can be tuned to interchangeable carrier wave.
[0095] Figure 11 shows the method 1100 that is used for gathering the information that is used to communicate by letter in wireless communication system (for example, system 200).Can pass through, for example, terminal is come manner of execution 1100.Method 1100 begins at square frame 1102 places, in square frame 1102, attempts detecting acquired signal on available system bandwidth complete all or substantially all of.In an example, can pass through base station and/or antenna groups, the part of acquired signal as super-frame preamble (for example, super-frame preamble 312) sent.In addition, acquired signal can be crossed over all or substantially all of entirely (for example, except protection whole the subcarrier 520 and/or 540) of carrier wave.In case 1102 places detect acquired signal at square frame, method 1100 advances to square frame 1104, in square frame 1104 based on the sub-carrier positions that is used for acquired signal in the carrier wave or the bigger subcarrier group of distributing to super-frame preamble determine the acquired signal that sends from sector (for example, the sector 104).In an example, the sector of determining in square frame 1104 places can be corresponding to the antenna groups in the base station in the system.In addition, at step 1104 place at least in part by being identified for determining the sector such as the sector mark of sector ID.Finally, method 1100 finishes at square frame 1106 places, gathers broadcast message in square frame 1106 on first broadcast channel and/or second broadcast channel.Yet, recognize that the action described in the square frame 1106 is optionally and can omits, for example, have sticky assignment or and dispatching under the situation of entity of manner of execution 1100.
[0096], provides the block diagram that shows the example wireless communications 1200 that is used to move one or more embodiment as herein described with reference now to Figure 12.In an example, system 1200 is multiple-input and multiple-output (MIMO) systems that comprised sender system 1210 and receiver system 1250.Yet, recognize, sender system 1210 and/or receiver system 1250 can also be applied to many single-input single-output system (SISO system)s, wherein, for example, a plurality of transmitting antennas (for example, on the base station) can send one or more symbols streams to individual antenna equipment (for example, mobile radio station).In addition, recognize, can use the each side of sender system 1210 as herein described and/or receiver system 1250 to single input aerial system in conjunction with single output.
[0097] according to an aspect, the traffic data at sender system 1210 places with a plurality of data flow is provided to transmission (TX) data processor 1214 from data source 1210.Then, in an example, send each data flow via separately transmitting antenna 1224.In addition, TX data processor 1214 can be based upon the specific encoding scheme that each data flow is separately selected, and the traffic data of each data flow is formatd, encodes and interweaves, so that coded data is provided.In an example, can use the OFDM technology subsequently, the coded data and the pilot data of each data flow is multiplexing.Pilot data can be, for example, and the given data form of Chu Liing in a known manner.In addition, can use pilot data to estimate channel response at receiver system 1250 places.Get back to sender system 1210 places, (for example can be based upon the selected specific modulation scheme of each data flow separately, BPSK, QSPK, M-PSK or M-QAM), multiplexing pilot tone and coded data to each data flow (are for example modulated, sign map), so that modulation symbol to be provided.In an example, can by on processor 1230, carry out and/or determine data transfer rate, coding and the modulation of each data flow in the instruction that provides by processor 1230.
[0098] then, the modulation symbol of all data flow can be offered TX processor 1220, it can further handle modulation symbol (for example, OFDM).Then, TX MIMO processor 1220 can be with N TIndividual stream of modulation symbols offers N TIndividual transmitter (TMTR) 1222a is to 1222t.In an example, each transmitter 1222 can receive and handle separately symbols streams so that one or more analog signals to be provided.Then, each transmitter 1222 can be regulated (for example, amplification, filtering and up-conversion) analog signal so that the modulation signal that is fit to the transmission on the mimo channel to be provided.Then, therefore, can be respectively from N TIndividual antenna 1224a sends the N to 1222t from transmitter 1222a to 1224t TIndividual modulation signal.
[0099], can pass through N according to another aspect RIndividual antenna 1252a receives the modulation signal that sends to 1252r at receiver system 1250 places.Then, the received signal from each antenna 1252 can be offered separately receiver (RCVR) 1254.In an example, each receiver 1254 can be regulated (for example, filtering, amplification and down-conversion) received signal separately, and the signal of this adjusting so that sampled digitalization to be provided, and is handled this sampling so that corresponding " reception " symbols streams to be provided then.Then, RX MIMO/ data processor 1260 can receive and handle from N based on specific receiver treatment technology RThe N of individual receiver 1254 RIndividual receiving symbol stream is to provide N TIndividual " detection " symbols streams.In an example, each detected symbol stream can comprise the symbol as the estimation of the modulation symbol that sends for corresponding data flow.Then, RX processor 1260 can be at least in part by demodulation, deinterleaving and decode each detected symbol stream handle each symbols streams, to recover the traffic data of corresponding data flow.Therefore, the processing by RX data processor 1218 can with by in the performed processing complementation of the TX MIMO at sender system 1210 places processor 1220 and TX data processor 1214.
