In addition, many aspects described herein or feature can be embodied as manufacturing a product of method, device or Application standard program and/or engineering.It is that want to comprise can be from the computer program of any computer readable device, carrier or medium access that term as used herein " manufactures a product ".For example, computer-readable medium (for example can comprise magnetic storage apparatus, hard disk, floppy disk, tape etc.), CD (for example, compact disc (CD), DVD (DVD) etc.), smart card and flash memory device (for example, EPROM, card, rod, key driving etc.).In addition, various storage medium described herein can represent one or more equipment and/or other is used for the machine readable media of storage information.Term " machine readable media " can comprise wireless channel and can store, comprises and/or carry multiple other medium of instruction and/or data, but be not restricted to this.
With reference now to Fig. 1,, the various aspects given according to this paper describe wireless communication system 100.System 100 can be included in the one or more base stations 102,104 in one or more sectors 106,108, base station 102, the 104 pairs of wireless communication signals receive, send, re-transmission etc., and service is offered each other and/or one or more mobile device 110,112.Base station 102,104 can be connected to infrastructure network (for example, the Internet), and therefore be provided to the connection of the Internet.According to some aspects, base station 102,104 can help peer-to-peer communications service (for example, the direct communication between mobile device 110 and 112).
Each base station 102,104 can comprise transmitter chain and receiver chain, recognize such as those skilled in the art, transmitter chain can comprise a plurality of assemblies (for example, processor, modulator, multiplexer, demodulator, demodulation multiplexer, the antenna relevant with the signal sending and receiving separately with receiver chain ...).Base station 102,104 can upward send to mobile device 110,112 with information at forward link (down link), and upper from mobile device 110,112 reception information at reverse link (up link).
In order to make mobile device 110,112 access base stations 102,104, and the service provide is provided or is used the frequency spectrum that is used for peer-to-peer communications, base station 102,104 some system information of broadcasting.According to some aspects, the broadcast message collection can be divided into one or more subsets.Some subsets can periodically be broadcasted according to predetermined broadcast cycle in base station 102,104, and different subsets can be associated from different broadcast cycle.According to some aspects, some subsets can be broadcasted with general message Signalling method in base station 102,104, and therefore, broadcast scheduling is not that be scheduled to or fixing (for example, can change selectively).
For example, the first broadcast message subset can be relevant with the basic configuration of system 100, and the ability of access system 100 is provided for mobile device 110,112.The first broadcast message subset can comprise one or more (the perhaps various combinations) in the following information: system timing information, spectrum allocation may information, power information, information on services, communication technology information, system version (compatibility) information, band information, service operator information, system loads information etc.This broadcast message tabulation is temporal evolution not.The below will provide with may be included in the first broadcast message subset in the relevant more information of information.
The second broadcast message subset can be relevant with switching.For example, mobile device 110 can move to another geographic area 108 from the first geographic area 106, and this causes the switching between two base stations 102,104.According to some aspects, two base stations 102,104 geographic area may overlap each other (shown in 114), so that mobile device 110,112 experiences the service disruption of considerably less (if any) between transfer period.
Different systems 100 parameter sets can be used in base station 102,104.For example, in ofdm system, spectral bandwidth is divided into many tones (tone).In each base station, these tones carry out frequency hopping according to specific frequency-hopping mode.Can control frequency-hopping mode by system parameters, and in order to make the interference between the base station 102,104 decentralized, different system parameter values can be selected in different base station 102,104.
System parameters allows mobile device 110,112 to move to another base station 104 from a base station 102.In order to alleviate the service disruption between transfer period, allow mobile device 110,112 to obtain rapidly system parameters, this is useful.Therefore, the second broadcast message subset can be less than the first broadcast message subset.For example, the second subset can comprise a seldom number fix information bit, and can carry out repeated broadcast to the second subset with the relatively short broadcast cycle time.Should be noted that this supposition has been connected to base station 102,104 with travelling carriage 110,112 when switching when occurring, and so travelling carriage 110,112 obtained at least a portion of the first broadcast message subset.
See Fig. 2, show according to the beacon signal 200 in example OFDM (OFDM) system of many aspects described herein.Can use the distinctive signal scheme or the signaling schemes that are called as beacon signal to transmit first and second (perhaps more) broadcast message subset.
The 202 representative times of transverse axis, the longitudinal axis 204 represents frequency.File (at 206 place's marks some files) a plurality of tones of representative in given symbol period.Each blockage such as square 208 represents a key signature, and it is at the independent tone of an independent transmission symbol on the cycle.The degree of freedom in the OFDM symbol is key signature 208.
Beacon signal 200 comprises sequence beacon signal burst, along with the time is carried out the order transmission to these beacon signal bursts.That the burst of beacon signal comprises is one or more (for example, a few) beacon symbols.Each beacon symbols can be the signal that sends in one degree of freedom, and its transmitted power is more much higher than the average every degree of freedom transmitted power on the relatively large time interval.
Show 4 little black squares, each little black square (210) represents a beacon signal symbol.The transmitted power of each beacon signal symbol is than the average every key signature transmitted power on the whole time interval 212 much higher (for example, high at least about 10 or 15dB).Each OFDM symbol period 214,216,218,220 is beacon signal bursts.In this explanation, each beacon signal burst is included in the beacon symbols of a transmission symbol on the cycle.
Fig. 3 shows the operable another kind of beacon signal 300 of one or more disclosed examples.Beacon signal 300 is similar to the beacon signal 200 of upper figure.Difference between these two beacon signals 200,300 is that beacon signal 300 is included in two continuous symbols have same tone on the cycle two beacon symbols.Especially, a beacon signal burst comprises two continuous OFDM symbol periods 312,314,316,318.
Fig. 4 shows the operable another kind of beacon signal 400 of one or more disclosed examples.This beacon signal is similar to above-mentioned beacon signal 200,300.Difference is in this beacon signal 400, and the burst of each beacon signal comprises may be continuous or may be discontinuous two OFDM symbol periods.Yet, in these two OFDM symbol periods, only send a beacon symbols.In given beacon signal burst, beacon symbols may appear in any one of these two cycles.For example, show two beacon burst 412 and 414.The beacon symbols of beacon burst 412 appears in the OFDM symbol period, and the beacon symbols of beacon burst 414 appears in the 2nd OFDM symbol period.
Among Fig. 2,3 and 4, the time location of beacon burst is predetermined.For example, in Fig. 2, pre-determine beacon burst and be positioned at OFDM symbol 214,216,218,220.In Fig. 3, pre-determine beacon burst and be positioned at the OFDM symbol to 312,314,316,318.In Fig. 4, pre-determine beacon burst and be positioned at the OFDM symbol to 412 and 414.
Can select the degree of freedom in the predetermined OFDM symbol, to send beacon symbols.For example, in Fig. 2, can select any one key signature in the OFDM symbol 214 to send beacon symbols, and in Fig. 4, can select the OFDM symbol to any one key signature in 412.Therefore, the degree of freedom sum of a beacon burst is twice among Fig. 2 among Fig. 4.
Fig. 5 shows the example system 500 that sends information subset independent of each other.Can be in cordless communication network use system 500, communicate each other and/or communicate with the base station to allow mobile device.The mode that system 500 can not affect with the change on first information subset second (perhaps more) information subset realizes information communication.Therefore, can there be and do not interfere with each other two kinds of different encoding schemes of (for example, independently of one another coding/decoding).This system comprises the one or more transmitters 502 that information are sent to one or more receivers 504.Transmitter 502 and/or receiver 504 can be other system components of base station, mobile device or the information of transmission.
Transmitter 502 can comprise first information flow-generator 506, and this first information flow-generator 506 can be analyzed and in a predefined manner broadcast singal is divided into a plurality of subgroups broadcast singal, produces first information stream.Additionally or replacedly, first information flow-generator 506 can determine which subgroup in one or more subgroups is used for specific broadcast singal.For example, can use first information stream to determine to use which subgroup.Broadcast singal is can be in time series or the time interval of an ofdm signal or good definition on a plurality of ofdm signals.For example, broadcast singal can comprise one or more symbol periods, and can be considered to degree of freedom piece.
First information flow-generator 506 can determine to use which subgroup or piece based on the information that will carry in the signal, and for example, this information can comprise the information relevant with peer-to-peer communications and/or the information relevant with cell communication.Can process this information by coding (for example, coded-bit).This coded-bit can have value " 0 " or " 1 ", and the transmission position of this bit can be based in part on bit value (" 0 " or " 1 ").
Figure 6 illustrates the expression of broadcast singal 600.Broadcast singal 600 is the subdivisions that are similar to above-mentioned beacon symbols 200,300,400 beacon symbols.Should be appreciated that, for example, broadcast singal 600 is an example just, and can use other broadcast symbols according to disclosed aspect.The 602 expression times of transverse axis, the longitudinal axis 604 expression frequencies.Example beacon symbols 600 comprises two symbol periods 606,608, for altogether 8 key signatures or the degree of freedom, these two symbol periods 606,608 each have 4 key signatures.
Whole degrees of freedom (for example, by first information flow-generator 506) in two symbol periods 606,608 of broadcast singal 600 are divided into the first bandwidth subset 610 and the second bandwidth subset 612.For example, key signature 0,1,2 and 3 can be in the first bandwidth subset or first 610, and key signature 4,5,6 and 7 can be in the second bandwidth subset or second 612.Should be appreciated that, can use other structure and other a number key signature piece, and simple scheme is described.Selected tone block 610,612 can be similar to fixing key signature and divide, and this fixing key signature is divided along with do not happen suddenly another beacon signal burst and changing of a beacon signal.Can for each piece uses identical division, perhaps according to some aspects, between each piece, can exist some times to change.
In given beacon signal burst, employed key signature piece or subset have been passed on information, can be referred to as information bit or piece encoding scheme { b 1.Which piece encoding scheme { b first information flow-generator 506 can determine will use during the specified beacon signal burst 1.
Should be noted that each the bandwidth subset 610, the 612nd in this example, continuous key signature piece.In addition, between two bandwidth subsets, can there be some untapped key signatures.Its reason is to alleviate owing to may lack timing and Frequency Synchronization between service station and the mobile device, and mobile device is thought the key signature in the bandwidth subset by mistake in another bandwidth subset another key signature.(not shown) in another example is divided bandwidth, so that the degree of freedom of each bandwidth subset interweaves mutually, in this case, the bandwidth subset can not be continuous key signature piece.
Should be appreciated that, first information flow-generator 506 can be determined the bandwidth subset division in other scene.For example, as shown in Figure 4, if a beacon burst comprises two OFDM symbols, whole degrees of freedom of two OFDM symbols can be divided into a plurality of bandwidth subsets so.Some bandwidth subsets can comprise the degree of freedom in the OFDM symbol, and another bandwidth subset can comprise the degree of freedom in the 2nd OFDM symbol.
System 500 can also comprise that the second bit stream generator 508, the second bit stream generators 508 can be determined which specific key signature (degree of freedom) of use in specific broadcast singal, produce the second information flow.According to some aspects, can use the second information flow to determine the waveform that in selected subgroup, uses.For each symbol period or each broadcast singal, the selected degree of freedom can be different.According to an aspect, by selecting the degree of freedom to transmit the first and second broadcast message subsets 610,612 for the beacon symbols in the beacon burst sequence.Especially, whole degrees of freedom of a beacon burst can be divided into a predetermined number bandwidth subset, these bandwidth subsets can be that separate or continuous.
In given beacon burst, the degree of freedom reception and registration that is used for the transmission broadcast symbols can be called as information bit or encoding scheme { c iInformation.Be independent of or no matter which subgroup first information flow-generator 506 has selected, come determine by the second bit stream generator 508 selected specific degrees of freedom.For example, the second bit stream generator 508 can be selected the specific tone symbol (perhaps encoding scheme { c in the subgroup i), and first information flow-generator 506 can be by selecting specific subgroup (perhaps piece encoding scheme { b 1) select actual tone.Owing to selecting independently of one another, so by 506 selected encoding scheme { b of first information flow-generator 1And by the second bit stream generator 508 selected encoding scheme { c 1Can occur with any order.
For example, first information flow-generator 506 may flow { b for the first information 1Select and comprise key signature 0,1, the first subgroup 610 of 2 and 3, and the second bit stream generator 508 may be the second information flow { c 1Select tone 2.Yet if first information flow-generator 506 selects to comprise key signature 4,5,6 and 7 the second subgroup 612 and the second bit stream generator 508 are selected same key signature position, this key signature will be key signature 6 so now.This is because key signature 6 in the position identical from key signature 2 (but in different subgroup 610,612), and the second bit stream generator 508 is indifferent to first information flow-generator 506 and has been selected which subgroup 610,612.
Use the various algorithms, method and/or the technology that are used for selecting encoding scheme, the second bit stream generator 508 can be based in part on encoding scheme { c 1Select the position of key signature in subgroup.Employed actual tone symbol is by 506 selected of first information flow-generators, particular sequence { c 1And the frequency hop sequences decision.Therefore, depend on first information flow-generator 506 has been selected which subgroup 610,612, this key signature in this example can be 0 or 4,1 or 5,2 or 6 or 3 or 7.Because encoding scheme { b 1And { c 1Independent of each other, if change any one encoding scheme, on the not impact of another encoding scheme.
Figure 7 illustrates the visual representation of the example codes scheme that the second bit stream generator 508 observes.Encoding scheme { c 1Timing is provided, and can be for frequency hopping, the presentation mode such as repeat.Encoding scheme { c 1Can repeat in the time (perhaps At All Other Times interval), this time can be the very little time interval.
The 702 representative times of transverse axis, the longitudinal axis represents frequency.At 702 places, show three different beacon symbols 708,710 and 712 on the top of figure.Be similar to beacon symbols illustrated in upper figure 600, each beacon symbols 708,710,712 the first half are that the first subgroup and Lower Half are the second subgroups, are expressed as respectively 714 and 716.As shown, first information flow-generator 506 can flow { b for the first information 1Select the second subgroup, the first subgroup of beacon signal 710 and second subgroup of beacon signal 712 of beacon signal 708.The second bit stream generator 508 can be the second information flow { c 1Select the position shown in the black blockage.Regardless of first information flow-generator 506 selected subgroups, in selected position, send high energy signals.In this example, the cycle only is 3, and the second information flow { c 1Can repeat.First information stream { b 1May have diverse periodicity.In other words, the second information flow { c 1The actual block that is positioned at is by first information stream { b 1Determine, yet, from the second information flow { c 1Angle, this coding does not change (because the second information flow { c 1Be indifferent in which piece send high energy signals).Periodically providing can be for the timing information that information bit is decoded.After having observed some sequences, can determine starting point and end point, this can provide determining timing in this piece.The below will provide the further information relevant with timing information.
Bottom 718 at figure shows from the broadcast singal of the angular observation of the second bit stream generator 508.718 couples of two information scheme { b of this part 1, { c 1Combination be illustrated, yet this is not that two information schemes are made up in suggestion; These streams remain scheme independent of each other, and only are to be expressed as combination for the purpose of explaining.
Like this, the second bit stream generator 508 is indifferent to and is not needed to know first information flow-generator 506 selected specific subgroups.This is because the second bit stream generator 508 only relates to the key signature position, may not be positioned at which group and do not relate to this key signature.
According to some aspects, can think information scheme { b 1And { c 1In different items.Coding is the mapping that information bit arrives the signaling position.Can think these information schemes { b 1And { c 1It is information bit.A large amount of { c that can send to some extent along with the time 1Information bit.Can also have coding " I ", it can be from { c 1In determine { Y iSequence, { Y iSequence is bit sequence, wherein { Y iIt is 1 bit.In Fig. 8, show this coding " I " at 802 places.
Continue above-mentioned example, show at 804 places have 3 symbol periods 806,808,810 broadcast singal, each symbol period has 4 degrees of freedom.If (for example, 0,1,3, provide the numbering of the degree of freedom ..., 11), this numbering indication signaling position that will occur so.Like this, { Y iCan be Y0, Y1, Y2, Y3 ... the sequence of Y11, this sequence can be based on periodically repeating.Like this, in this example, any specific { Y iCan equal from 0 to 11.
Information bit { b independently 1Sequence has for generation of signal { X iDissimilar coding (for example, coding " II ").Like this, coding II={X i.{ X iSelf have some may with { Y iIrrelevant periodicity.Each { X iCan equal 0 to by first information flow-generator 508 selected subgroup numbers.In this example, { X iCan equal " 0 " or " 1 ", wherein, " 0 " represents the first subgroup, and " 1 " represents the second subgroup.
As illustrated in fig. 9, information flow synthesizer 510 can utilize following formula to information bit { X iAnd { Y iMake up, with generation value Z i, wherein, Q represents the maximum of first information stream:
Z i={ X i* Q+{Y iFormula (1)
As example illustrated in fig. 10, can the value of thinking Z iIt is the broadcast singal 1000 that takies greater room.In this example, with the degree of freedom be labeled as 0,1,2,3 ..., 23.Can (for example, by first information flow-generator 506) broadcast singal 1000 be divided into two or more pieces or subgroup 1002 and 1004, each piece or subgroup comprise 12 tones (for this example, it is value Q).
In illustrated example, { X iEqual " 0 " for subgroup 1002, and equal 1 for subgroup 1004.Utilize formula 1, if { X iEqual " 0 ", so Z iEqual { Y i, it is upper interval or the first subgroup 1002.Yet, if { X iEqual " 1 ", so starting point be between lower region or the second subgroup 1104 in the degree of freedom " 12 ".Therefore, { X iWhich piece or subgroup have been selected in indication, and { Y iPosition in the indicator collet, even this is so that may make up independent encoding scheme with transmission information and also allow coding independent of one another.Should be noted that can according to from shown in and the different mode of institute's describing mode cut apart.

Memory 1112 can be operably connected to receiver 1102, and memory 1112 can be stored information and/or preserves about the information that receives being carried out decipher and/or the information that receives being split into the instruction of information subconstiuent in communication.Memory 1112 can be stored and the information-related information that is included in each subconstiuent.

Figure 13 shows the example beacon signal when with the relatively short broadcast cycle time the second broadcast message subset being carried out repeated broadcast.The 1302 representative times of transverse axis, the longitudinal axis 1304 represents frequency.In this example, in a beacon burst, the degree of freedom is divided into two bandwidth subsets: have label ({ X for example i) subset 1306 of " 0 " and have label ({ X for example i) subset 1308 of " 1 ".In this example, each bandwidth subset 1306,1308 comprises 8 key signatures, and the ({ Y for example of the relative label from the top to the bottom i) be 0,1 ... 7.
The second information bit sequence corresponding to the second subset 1308 comprises fixing and limited sets of bits, this sets of bits is repeated to send in three continuous beacon burst.For example, the second information bit sequence has been determined 3 relative labels ({ Y for example i) r1, r2 and r3.In beacon burst 1310, use r1 to determine the relative label (in this example, relatively label=3) of beacon symbols, as shown in 1312.In beacon burst 1314, use r2 to determine the relative label (in this example, relatively label=5) of beacon symbols, as shown in 1316.In beacon burst 1318, use r3 to determine the relative label (in this example, relatively label=6) of beacon symbols, as shown in 1320.This pattern is along with the time repeats: in beacon burst 1322, use r1 to determine the relative label (in this example, relatively label=3) of beacon symbols, as shown in 1324.In beacon burst 1326, use r2 to determine the relative label (in this example, relatively label=5) of beacon symbols, as shown in 1328.In beacon burst 1330, use r3 to determine the relative label (in this example, relatively label=6) of beacon symbols, as shown in 1332, by that analogy.
Simultaneously, the first information bit sequence corresponding to the first subset comprises more bits.Especially, first information bit sequence is determined a sequence bandwidth subset label ({ X for example i) m1, m2, m3, m4, m5, m6 etc.In beacon burst 1310, use m1 to determine the label (in this example, subset label=0) of bandwidth subset.In beacon burst 1314, use m2 to determine the label (in this example, subset label=0) of bandwidth subset.In beacon burst 1318, use m3 to determine the label (in this example, subset label=1) of bandwidth subset.In beacon burst 1322, use m4 to determine the label (in this example, subset label=1) of bandwidth subset.In beacon burst 1326, use m5 to determine the label (in this example, subset label=0) of bandwidth subset.In beacon burst 1330, use m6 to determine the label (in this example, subset label=0) of bandwidth subset.Notice, label r1, r2, r3 repeat in short broadcast cycle relatively, and subset label m1, m2 ... can in much longer broadcast cycle, repeat or can not repeat not fully.
In an example of the system that uses about 1.25MHz bandwidth, total bandwidth is divided into 113 tones.A beacon burst comprises one or two OFDM symbol period.In beacon burst, these tones are divided into two or three bandwidth subsets, each bandwidth subset is included in 37 key signatures (for example, M=2 or 3, and K=37) in the given OFDM symbol period.Label repeats in per 18 continuous beacon burst relatively.
Although not shown, replacedly, may transmit the first broadcast message subset with relative label, and dedicated bandwidth subset label transmits the second broadcast message subset.
With reference now to Figure 14,, shows the exemplary method 1400 that in broadcast singal, sends the broadcast message sets of bits of realizing according to disclosed aspect.Simultaneously, purpose for illustrative ease, with the method representation in this detailed description and be described as a series of actions, should be appreciated that and recognize, the method is not subjected to the restriction of running order, according to one or more aspects, some actions can occur and/or occur simultaneously with other action with the different order of represented from this paper and described order.For example, it should be appreciated by those skilled in the art that and recognize, replacedly, can be with method representation for such as a series of state or the events of being mutually related in state diagram.In addition, according to one or more aspects, can not need all illustrated actions to come implementation method.
In given beacon burst, beacon symbols can transmit with the one degree of freedom in the degree of freedom the first and second broadcast message subsets with all.The selected degree of freedom belongs to a bandwidth subset in a plurality of bandwidth subsets.In given beacon burst, the first broadcast message subset is encoded, should use which bandwidth subset (for example, piece) to select beacon signal, simultaneously the second broadcast message subset is encoded, should use which degree of freedom in the selected bandwidth subset to determine beacon signal.
Can represent the first broadcast message subset by first information bit sequence, and can represent the second broadcast message subset by the second information bit sequence.The first broadcast message subset can be relevant with basic configuration, and this basic configuration can comprise the spectrum disposition information for peer communications devices, to determine how to use special frequency band.This frequency band can be identical from the frequency band that sends therein broadcast message or different.Whether spectrum disposition information can indicate the peer communications devices can be for peer-to-peer communications uses specific frequency band, and if can use, then be that power budget is determined in the peer-to-peer communications transmission.For example, the second broadcast message subset can be relevant with switching.According to some aspects, the second broadcast message subset does not comprise the information relevant with peer-to-peer communications.Should be appreciated that, information bit sequence can comprise broadcast message and some redundant bit (for example, Parity Check Bits) that is used for coding protection.In given beacon burst, can send the part of first information bit sequence and the part of the second information bit sequence.
Method 1400 can be used predetermined bandwidth degree of freedom collection transmission bandwidth information sets of bits, and method 1400 begins at 1402 places, generates the first broadcast message bit subset and the second broadcast message bit subset.Can from a plurality of broadcast message bits, generate two broadcast message bit subset, and can generate in a predetermined manner.At 1404 places, predetermined bandwidth degree of freedom collection is divided into two or more subsets.Each bandwidth degree of freedom subset can comprise a plurality of bandwidth degrees of freedom.
At 1406 places, be that the broadcast message bit is selected the subset in two or more bandwidth degree of freedom subsets at least according to the first broadcast message bit subset.These subgroups can be each other continuous or mutually away from.According to some aspects, the first and second broadcast message bit subset are subsets of the not adjacency in the broadcast message sets of bits.These subgroups can be divided into a plurality of degree of freedom subsets.Each bandwidth degree of freedom in the tone can be an OFDM symbol.
At 1408 places, select at least one bandwidth degree of freedom in the selected subset according to the second broadcast message bit subset.At 1408 places, during selected bandwidth degree of freedom subset, send beacon signal.According to some aspects, can basically send simultaneously beacon signal with other signal.For example, beacon signal can be superimposed upon on other signal.Can send this beacon symbols to compare higher energy with other beacon symbols.This beacon signal can comprise the piece sequence that occurs in time.
According to some aspects, at least one subset in two or more broadcast message bit subset comprises the control information that is used for peer-to-peer communications that wireless device will receive, and in peer-to-peer communications, wireless device and another wireless device directly communicate.This control information can comprise the combination in any of the one or more or following information in the following information: the frequency band positional information, whether allow peer-to-peer communications in frequency band, wireless device is used for the control parameter that the maximum transmit power of peer-to-peer communications is controlled.
Determine to use in two or more bandwidth subsets which at 1402 places, and determine that at 1404 places which degree of freedom in the selected bandwidth subset is used for sending beacon symbols, these two operations can be carried out independently of one another.For the purpose of example rather than restriction, with absolute label a=0,1 ... N-1 is numbered the usable tone symbol in the given beacon burst, and wherein, N is the integer that represents the usable tone total number of symbols.In each bandwidth subset, with relative label r=0,1 ... K is numbered key signature, and wherein, K is that representative is at the integer of each bandwidth subset medium pitch number of symbols.In this example, the number of the key signature in each bandwidth subset is identical.In addition, pass through s=s 0, s 1..., s M-1Provide the absolute label of the first key signature (for example, the key signature that relative label equals 0) in each bandwidth subset, wherein, M is the integer that represents the bandwidth number of subsets.Therefore, for given key signature, absolute label (a) is relevant, as follows with relative label (r) with the label (m) of the bandwidth subset that this key signature belongs to:
A=s m+ r formula (4)
At 1402 places, can determine by the information sequence of the first broadcast message subset the label (m) of bandwidth subset.At 1404 places, can determine relative label (r) by the information sequence of the second broadcast message subset.Should be noted that to carry out independently of one another and determine m at 1402 places and determine r at 1404 places.At 1408 places, from m and r, calculate the absolute label (a) of this beacon symbols.From a beacon burst to another beacon burst, owing to determine m with the different piece of this information sequence, so beacon symbols can use different bandwidth subsets.
According to disclosed aspect, can carry out independently of one another the Code And Decode to the first and second broadcast message subsets.For example, when changing the encoding scheme of the first broadcast message subset, on the not impact of Code And Decode of the second broadcast message subset, and when changing the encoding scheme of the second broadcast message subset, on the not impact of Code And Decode of the first broadcast message subset.In addition, because m along with the time changes, so beacon symbols produces from different bandwidth subsets, has therefore increased diversity.
Figure 15 shows the exemplary method 1500 from two broadcast message subsets of beacon symbols decoding according to various aspects.This beacon symbols can comprise the piece sequence that occurs in time.At 1502 places, method 1500 beginnings receive signal in beacon burst in the time cycle.Can this signal be received comparing on the higher energy with the signal that other receives.In addition, can basically receive this signal simultaneously with other signal.Can basically determine to send therein simultaneously with the reception of this signal the degree of freedom of this beacon symbols.In order to determine this degree of freedom, utilized every degree of freedom transmitted power of this beacon symbols than much higher this fact of average transmitting power.
At 1504 places, determine this beacon symbols belongs to which (for example, the receiving this beacon symbols in this bandwidth subset) in predetermined a plurality of bandwidth subsets.Determine the degree of freedom that is used for receiving therein beacon symbols in selected bandwidth subset at 1506 places.Can use result's difference reconstruct the first and second broadcast message subsets of 1504 and 1506.The first subset can be relevant with basic configuration, and the second subset can be relevant with switching.
Should be appreciated that, can carry out independently of one another and determine that at 1504 places this beacon symbols belongs to which the bandwidth subset in predetermined a plurality of bandwidth subsets and determines the degree of freedom that is used for sending therein this beacon symbols in selected bandwidth subset at 1506 places.Continue the example of Figure 14, detect the absolute label (a) of received signal symbol.Because the bandwidth subset is adjacency not in this example, so can obtain uniquely label m and r from a.In case pre-determined the bandwidth subset, m determines just depend on which bandwidth subset absolute label (a) falls into, and therefore is independent of determining of r.
Figure 16 shows the example of the method 1600 that the base station is operated.Method 1600 begins at 1602 places, at 1602 places, the first value is distributed to first information stream.First information stream can represent the first broadcast message subset.The first value is distributed to first information stream can be comprised a plurality of information bit { c iIn each encode, and from { c iIn determine bit { Y iSequence, wherein, { Y iThe independent bit of representative.{ Y iBit sequence can be based on periodically.
At 1604 places, the second value is distributed to the second information flow.The second information flow can represent the second broadcast message subset.The second value is distributed to the second information flow can be comprised information bit { b iEncode, and from { b iMiddle signal { the X that produces i.Signal { X iCan have and be independent of { Y iThe periodic periodicity of bit sequence.
Can make up first information stream and the second information flow at 1606 places.This combination allows basically to send simultaneously two information flows (if necessary).Yet the value of each stream is different and obtains independently of one another.Can adopt formula (Z i={ X i* Q+{Y i) calculate the combination to the first and second information flows.In the formula, { Y iRepresent and distribute to the first value that the first information flows, { X iThe second value of the second information flow is distributed in representative, and Q represents the maximum of first information stream.The information flow that makes up can produce broadcast singal, and this broadcast singal takies than the space of first information stream and the larger space, space of the second information flow.
At 1608 places, the value that makes up or stowed value produce stowed value.At 1610 places, send the waveform that depends on this stowed value.This waveform can comprise the high-energy beacon symbols.Every degree of freedom transmitted power of this beacon symbols can be than the transmitted power height that sends other signal 10dB at least.This waveform can take the very little degree of freedom.The recipient of expection can receive this waveform, and this stowed value is divided into subconstiuent (for example, first information stream and the second information flow).Figure 17 shows the exemplary method 1700 that the waveform that receives is made an explanation in communication.Can receive waveform from the transmitter that uses the method 1600 of discussing with reference to upper figure represents.
When receiving the high-energy beacon signal that is included in the waveform, method 1700 begins at 1702 places.The signal that receives can comprise the combination of the first value and the second value.The combination of the first value and the second value comprises broadcast singal, and this broadcast singal takies than the space of first information stream and the larger space, space of the second information flow.Can be on high-energy this signal be received and/or this signal can take the very little degree of freedom.Additionally or replacedly, can basically receive this signal simultaneously with other signal.
Basically side by side this waveform is resolved at least two subconstiuents or at least two values with this waveform of reception.At 1704 places, the first value of identification first information stream, and at 1706 places, determine the second value of the second information flow.First information stream can represent the first broadcast message subset, and the second information flow can represent the second broadcast message subset.Can be independently or carry out the identification of above-mentioned stream and determine with any order.Therefore, if change coding and/or the decoding of a stream, do not affect coding and/or the decoding of another stream.
The first value is interpreted as first information stream can comprises definite { c iIn the bit { Y that comprises iSequence and to a plurality of information bit { c iIn each decode, wherein, { Y iThe independent bit of representative.The second value is interpreted as the second information flow can be comprised by { b 1In the X that comprises iThe signal that determines receives, and decoded information bit { b 1.
According to some aspects, the first value made an explanation to be comprised { Y iBit sequence decodes, and the second value made an explanation comprise signal { X iDecode.Signal { X iHave and be independent of { Y iThe periodic periodicity of bit sequence.
Figure 18 shows the exemplary method 1800 of assembling for the frequency tone that sends in information glossary of symbols service time.May be desirably in the different information subset of transmission between an independent transmission period.The applicability (for example, system parameter message, handover information etc.) that depends on information butt joint receipts person can be expected different information subset is used for identical or different recipients.Method 1800 allows one or more subconstiuents of transmission information are made amendment, and does not affect other subconstiuent of information.
At 1802 places, at least some periodicity pitches and some time symbols are appointed as piece.Piece can comprise that the frequency tone in the time glossary of symbols assembles.This piece can represent the time period that sends information during it, and can repeat along with the time.At 1804 places, a piece can be divided into two or more subgroups.Each subgroup can comprise the periodicity pitch subset in the time character subset.These subgroups can represent first information stream (for example, { b 1).These subgroups can be adjacent one another are or adjacency not each other.At 1806 places, two or more subgroups are divided into a plurality of microliths.Each microlith can comprise at least one periodicity pitch in the time symbol.Each microlith can represent the second information flow (for example, { c 1).These microliths need not to be equally spaced.Mapping can be based on the first and second information flows, and in frequency with can be mutually exclusive on the time.That is to say, changing an information flow does not affect another information flow.Therefore, changing frequency or the first subconstiuent (for example, subgroup) does not cause regularly (for example, microlith) or the second subconstiuent to change.
At 1808 places, for communication is selected a microlith (for example, the degree of freedom) in a plurality of microliths in one of two or more subgroups.The selection of subgroup and the selection of microlith representative are included in the information in institute's transmission information.Can select these subgroups according to first information stream, and can select these microliths according to the second information flow.In selected microlith, compare with unselected microlith, send information with higher energy.
Figure 19 shows the exemplary method 1900 that makes an explanation for the reception signal to the periodicity pitch symbol in the expression time glossary of symbols.At 1902 places, receiving broadcasting information.Can receive this broadcast message in a microlith of selecting from a piece, this microlith can comprise the one or more periodicity pitches in the time symbol.This broadcast message can comprise two or more information subset of the combination in order to send an independent signal (for example, microlith).The information that the position representative information receiver of this signal internal information subset should be decoded is with the signal that abundant assessment was received.Information decoded is included in the subgroup that 1904 places determine that from least two subgroups this microlith belongs to, and comprises the piece of this subgroup in the identification of 1906 places.This piece can comprise that the frequency tone in the time glossary of symbols assembles.This subgroup can represent first information stream or can select according to first information stream, and this microlith can represent the second information flow or can select according to the second information flow.Being mapped in frequency and being mutually exclusive on the time based on the first and second information flows.Definite information that is included in institute's transmission information of having passed on of this subgroup and this microlith.Can carry out the decoding to first information stream, and not affect the decoding to the second information flow.
According to some aspects, in given beacon burst, use which degree of freedom to send beacon symbols and passed on information.Each effective beacon burst sends an information symbol, and the value of this information symbol equals element in the reserved word matrix.Supposing has K the degree of freedom to can be used for beacon signal in a beacon burst, and with these degrees of freedom be numbered 0,1 ... K-1.In example, with alphabet be given as 0,1 ... K-1: the value of information symbol equals the label of the employed degree of freedom of beacon symbols.In this case, alphabetic(al) size equals K.In another example, alphabetic(al) size can be less than the number of the degree of freedom in the beacon burst.For example, given alphabet is 0 and 1: if the label of the employed degree of freedom of beacon symbols less than floor (K/2), information symbol can equal 0 so.In another example, given alphabet is 0 and 1: if the label of the employed degree of freedom of beacon symbols is even number, information symbol can equal 0 so, otherwise equals 1.
N represents alphabetic(al) size.In an example, can use the information symbol in the independent beacon burst to send a fixed integer order broadcast message bit.For example, if N=2 can use an information symbol to send 1 bit so.In another example, can use a predetermined number information symbol to send a fixed integer number broadcast message bit, this predetermined number information bit can be continuous.For example, if N=3, two information symbols can represent 9 different values together so.Can use 8 in these values to send 3 bits, keep a remaining value.Therefore, a sequence beacon burst can transmit a sequence broadcast information bit.
According to some examples, a plurality of beacon burst are carried out the periodicity numbering.For example, return with reference to figure 2, beacon burst 214 is numbered 0.Beacon burst 216 is numbered 1 and beacon burst 218 is numbered 2.Then repeat this numbering: beacon burst 220 is numbered 0, by that analogy.Can transmit by beacon symbols entrained in the beacon burst sequence this numbering structure.
For example, consider wherein, alphabet to be given as 0 and 1 by Fig. 2: if the label of the employed degree of freedom of beacon symbols less than floor (K/2), information symbol can equal 0 so, otherwise equals 1, wherein, K is the number of the degree of freedom.In fact, this signaling schemes is divided into two bandwidth subsets with the degree of freedom: those degrees of freedom that label is greater than or equal to floor (K/2) less than those degrees of freedom and the label of floor (K/2).In a beacon burst, which bandwidth subset to transmit information symbol by being chosen as beacon symbols with.Simultaneously, can be numbered the degree of freedom in the bandwidth subset with relative label, and can in each beacon burst, transmit relative label.Comprising in the time interval of several beacon burst, can use the sequence of relative label to provide and comprise the additional information of numbering structure.
This numbering structure is actually synchronization structure, and should be able to use in an example, in this example, can use predetermined a plurality of information symbols to send a fixed integer number broadcast message bit.In this case, this numbering structure helps to determine which information symbol to determine the broadcast message bit with together.For example, in Fig. 2, the alphabet size of supposing the information symbol in each beacon burst is 3.Beacon burst 214 and 216 information symbol can be united and transmitted 3 bits, and the information symbol of beacon burst 218 and 220 can be united and transmitted other 3 bits.This numbering structure helps 214 and 216 marshalling is identified, so that receiving equipment can not made mistakes owing to being grouped in together 216 and 218.
According to some aspects, can from the information symbol sequence of observing along with the time, obtain this numbering structure fully.For example, in above-mentioned example, the alphabet size of an information symbol is 3, and therefore, a pair of information symbol can transmit 9 different values.Use in these values 8 to transmit 3 bits, and keep or do not use last value.Receiving equipment can utilize " blindly " said structure to obtain this numbering structure.Especially, receiving equipment can be supposed the first numbering structure, and checks each to (214,216), (218,220) etc., and all these are not to all will having the value that is retained, and accordingly, receiving equipment can conclude whether correct the numbering structure of supposing is.On the other hand, receiving equipment can also be supposed the second numbering structure, and checks each to (216 and 218) etc., and randomly, some will be to having the value that is retained, and accordingly, receiving equipment can conclude that the numbering structure of supposing is incorrect.
Generally, existence can be used two or more information flows that broadcast singal sends.First information stream is used by most of cellular network usually, and comprises some parameters of determining the out of Memory of base station identity such as cell ID, sector mark, transmitted power, access power and help mobile device.This is first-class to comprise that mobile device is used for determining the parameter that it when should access base station, when should switch etc.
Second or information type can be the information for supporting cellular and non-cellular application.For example, although there is licensed-in frequency spectrum, may also expect to allow peer-to-peer network, wherein, some mobile device can be carried out self-assembly to alleviate the pressure through the base station.Yet, be that the service provider may not have the ownership that the frequency spectrum of communication is set up in expectation thereon with allowing mobile device to set up at random the type challenge that is associated of communicating by letter.For example, the service provider of facility registration may have the frequency spectrum ownership in the east coast, but may not have the frequency spectrum ownership in the West Coast.The service provider who has this frequency spectrum in the West Coast does not want to allow and communicates in the frequency spectrum of unregistered equipment at it.Therefore, before can setting up communication, equipment need to be from the information of local service provider.
In another example, may have untapped frequency spectrum now, and equipment can be set up peer-to-peer communications.Yet, in some years from now on, may build infrastructure, and the owner (for example, service provider) of this infrastructure (for example, frequency spectrum) will no longer allow peer-to-peer communications.Therefore, the service provider wants to set up the control relevant with how using frequency spectrum.Therefore, mobile device should obtain this information before it begins to send in these positions.
According to some aspects, can be used for Ultra-Mobile Broadband (UMB) information owing to first-class, so the information relevant with how using frequency spectrum can be placed in the second, can the information relevant with how using frequency spectrum be called progressive information.Progressive information can be very not urgent, and the time that mobile device is intercepted is longer, and it is larger that the information content that receives will become.
Can with one in described two encoding schemes before to first or second in any one encode.For example, can be with the first-class information bit { b that is encoded to i, and second can be encoded to information bit { c i.Replacedly, second can be encoded to information bit { b i, and can be with the first-class information bit { c that is encoded to i.
With reference now to Figure 20,, shown in the figure is to comprise that regularly (for example, synchronous) information is in the part of interior broadcast 2000.The 2002 expression times of transverse axis.In concept, broadcast 2000 is message bit stream { b i.In square frame 2004, send b 1In square frame 2006, send b 2And in square frame 2008, send b 3In order to transmit timing information, square frame 2004,2006,2008 should have a kind of pattern (for example, timing mode) or numbering, this message is made an explanation with suitable order to allow receiving equipment.
For example, if broadcast with square frame b 12004 beginnings, may exist should be at square frame b 2Some content of broadcasting in 2006.This can carry out with the mechanism of numbering, and can find in several ways this numbering mechanism, for example, finds { c i, if { c iHave specific period, can carry out linear broadcast to it.In case to { c iCarried out decoding and found periodicity, just can periodically be used for timing difference.According to some aspects, can use at { c iOn the information of carrying find numbering mechanism.
As illustrated in fig. 21, in another example, can use { b iDetermine starting point.For example, can carry 3 ranks at every turn.The 2102 expression times of transverse axis, and have 3 information bits 2104,2106 and 2108.Each piece in this information bit can send 1,2 or 3 (for example, 3 ranks). Information bit 2104,2106,2108 can transmit 9 ranks (0 to 8) jointly.Can keep or do not use last rank " 8 ", perhaps can use last rank " 8 " carry information rather than regularly.
Add another rank with the 4th bit 2110 and brought problem, this is because transmitter can be selected any bit combination (for example, 2104 and 2106; 2106 and 2108; 2108 and 2110) and receiver may not know to have received which bit.Yet, according to this example, because bit 2108 has carried the bit number 8 that should not use, should not use bit 2108.Therefore, if selected incorrect combination (for example, 2106 and 2108), there is so a kind of possibility: owing to be numeric coding, so receiver will be seen bit 8.If receiver finds bit 8, then regularly misalignment of indication, this provides a kind of timing architecture (for example, owing to thinking that 8 should not be in the there, so it is wrong).
For regularly definite, example example as shown in Figure 22, receiver obtains timing information and bit stream, and this timing information and bit stream can provide mark or designator.This allows definition may have the phase structure of synchronization message and asynchronous message.For example, the first two bit after mark 2202,2204 carries some synchronization messages (for example, position itself provides with how the message relevant information that makes an explanation).This synchronization message needn't have message, and position itself is exactly message.The remainder of this message (for example, each bit) can together as asynchronous message, can piece together them to obtain head/main body/message.Can not necessarily by place or position, determine starting point and end point by message format.
Receiving equipment is intercepted duration of this message when longer, will receive more bits.In synchronization message, can there be many group synchronization messages, wherein, some message repeat at different time in some time repetition and other message.Shown in Figure 23 to this example message that repeats to illustrate, wherein, message " A " is frequent to repeat (shown in 2302,2304,2306), and message " B " and " C " have different periodicity (respectively as 2308,2310 and 2312,2314 shown in).Therefore, because position itself becomes the timing that the explanation to bit defines, so may have different periodicity for different synchronization messages.
This message can comprise with how to use frequency spectrum, permission equipment uses the relevant customizing messages of the combination of frequency spectrum and/or out of Memory or above-mentioned information.For example, if in frequency spectrum " 1 " broadcasting this message, this message needn't advise whether can using this frequency spectrum, it only indicating equipment can use frequency spectrum " 2 ", wherein, frequency spectrum " 2 " is unaffected waveform.Therefore, this message needn't relate to the frequency spectrum of just therein this broadcast being broadcasted, may available other frequency spectrum but can relate to.Receiving equipment can be intercepted this specific part of this message, and makes decision and use available another frequency spectrum.The message of the indication current frequency spectrum of use or another frequency spectrum can be in synchronization message or asynchronous message.
Figure 24 shows the example system 2400 that comprises the broadcast message bit sequence of one or more subsequences for transmission.System 2400 comprises one or more transmitters 2402, and these one or more transmitters 2402 arrive one or more receivers 2404 with information broadcasting.Broadcasting schedule table can be determined and change to transmitter 2402.For example, transmitter 2402 can be compared other message and more continually some message be broadcasted, and/or only broadcast some message once or several times, and or else repeats subsequently.
Transmitter can comprise arrangement device 2406, arranges device 2406 can define one or more broadcast message bit subsequences, and the structure of the interior one or more subsequences of definite broadcast.Can be the position of each subsequence in this broadcast with this organization definition.Determining of position can be predefined.
Sequence can have certain structure (for example, numbering/timing architecture), can be by obtaining device 2408 these structures of configuration, with place or the position of indication each subsequence in broadcast or signal.The broadcast message collection can comprise a plurality of subsets, and wherein, broadcasting equipment 2410 uses specific subsequence to send each broadcast message subset.According to some aspects, these subsequences can be interweaved each other.
Memory 2412 can be operably connected to receiver 2402, and memory 2412 can be stored information and/or preserves and define one or more broadcast message bit subsequences and determine to be included in the relevant instruction of the structure of the subsequence in the broadcast singal.Timing architecture can be coded in the broadcast singal.
Memory 2412 can also preserve with to each subsequence begin carry out mark and send the relevant instruction of broadcast singal.To each subsequence begin carry out mark and can define a kind of phase structure or timing architecture.The beginning of each indicated subsequence can allow synchronization message and asynchronous message are included in the broadcast singal.Broadcast singal can comprise asynchronous message, synchronization message or its combination.According to some aspects, information has been passed in the position of message.Asynchronous message can comprise the message header that the asynchronous information definition is provided.The definition of synchronization message can be depended on the position of this synchronization message in broadcast singal.
Two or more included in broadcast singal subsequences can have different periodicity, perhaps can be interlaced with one another.According to some aspects, the broadcast cycle of a subsequence is 1 second at least, and a broadcast cycle sends with connecing another broadcast cycle.Additionally or replacedly, broadcast singal comprises with the use of frequency spectrum, allows to use equipment or the relevant information of its combination of frequency spectrum.
Processor 2414 can be operably connected to receiver 2404 (and/or memory 2412), realizing the analysis to received information, and/or processor 2414 can be carried out the instruction that is kept in the memory 2412.Processor 2414 can be to be exclusively used in the processor that arranges device 2406, acquisition device 2408 and/or broadcasting equipment 2410 operable information is analyzed and/or generated to the information that receives from transmitter 2402.Additionally or replacedly, processor 2414 can be the processor that one or more assemblies of system 2400 are controlled, and/or to information analyze, information generated and/or processor that one or more assemblies of system 2400 are controlled.
With reference now to Figure 25,, shows for the example system 2500 that the broadcast singal that comprises a plurality of subsequences is made an explanation.Transmitter 2502 can be broadcasted the message that receiver 2504 is mail in expection.Broadcast message can comprise a plurality of subsequences and can comprise an independent subsequence.For subsequence is made an explanation, receiver 2504 can comprise regularly locator 2506, message header definition device 2508 and evaluator 2510.
Regularly locator 2506 can be assessed the broadcast that receives, and determines a kind of timing architecture.According to some aspects, the form of the subsequence at least one subsequence subset the explanation of the bit that transmits in subsequence (for example, to) can be to come predefined according to the position in the subsequence.This form can repeat according to predetermined broadcast cycle.For example, the information bit that transmits in subsequence can repeat according to broadcast cycle.Therefore, send information with the method for synchronization, and subsequence is called synchronous subsequence.According to some aspects, different subsequences can have different broadcast cycle.
According to some aspects, the form of some subsequences is not to come predetermined according to the position in the subsequence.The information bit that transmits in subsequence can belong to different broadcasts, and these different broadcasts are not predetermined or fixing.Each message can comprise at least one in message header and the source body.Therefore, can send message with asynchronous system, and subsequence can be called asynchronous subsequence.Message header definition device 2508 can be assessed broadcast singal (perhaps being included in the subsequence in the broadcast singal), so that head is defined.
According to some aspects, subsequence and asynchronous subsequence can coexist in the broadcast message sequence synchronously.In short time interval, receiver 2504 should be able to obtain necessary broadcast message from beacon signal, with access transmitter (for example, service station).Along with the time goes over, receiver 2504 can receive increasing beacon burst, and can accumulate increasing broadcast message bit.
Based on the information that receives and explain by defined message header at least in part, whether evaluator 2510 can be made receiver 2504 should be from the first spectral change to the second frequency spectrum, rest on current frequency spectrum, change the decision of its transmitted power or other parameter.
For example, the first mobile device is wanted to set up communicate by letter (for example, peer-to-peer communications) with the second mobile device.The base station that the geographic area that two mobile devices are positioned at is served can broadcast.These equipment use specific frequency spectrum they can set up the information of peer-to-peer communications so if broadcast can comprise indication.Be similar in the message shown in Figure 23, can send this broadcast at channel " A ".The purpose of channel " B " can provide different periodicity.Each mobile device will find the timing of this message, to determine how bit is made an explanation.In case explained these bits, can assess these bits, to determine whether using certain frequency spectrum, whether there are communication priority or out of Memory.The extraneous information that can provide is power information, and for example mobile device only can use the indication of the power that is lower than threshold level.Additionally or replacedly, can there be the physical layer that equipment should have for the transmission of determining separately/mac layer parameter.
Memory 2512 can be operably connected to receiver 2502, and memory 2512 can be stored information and/or preserves and the broadcast message that comprises at least one broadcast message bit subsequence is received relevant instruction.This subsequence can comprise at least one asynchronous message or at least one synchronization message or its combination.The definition of synchronization message can be depended on the position of this synchronization message in broadcast singal, and asynchronous message can comprise message header, and this message header provides the definition of asynchronous message.
Memory 215 can also be preserved with the location that the starting position that is included in each subsequence in the broadcast singal that receives is positioned and is based in part on this starting position the relevant instruction of decoding of at least one subsequence.Find the starting position can comprise that the designator to being included in the beacon signal positions.The starting position of synchronization message can convey a message.Memory 2512 can also be preserved and be based in part on the message explained to the relevant instruction of making amendment of at least one parameter.
Processor 2514 can be operably connected to receiver 2504 (and/or memory 2512), realizing the analysis to received information, and/or processor 2514 can be carried out the instruction that is kept in the memory 2512.Processor 2514 can be to be exclusively used in the processor that can be obtained by information flow the information of device 2506, first information stream analyzer 2508 and/or 2510 uses of the second information scheme interpreter is analyzed and/or generated to the information that receives from transmitter 2502.Additionally or replacedly, processor 2514 can be the processor that one or more assemblies of system 2500 are controlled, and/or analytical information, information generated and/or processor that one or more assemblies of system 2500 are controlled.
According to some aspects, the broadcast message bit sequence comprises a plurality of sequences.Figure 26 shows the example that broadcast message bit sequence 2600 is divided into a plurality of subsequences of realizing according to disclosed aspect.
Transverse axis 2602 representatives send the logical time of broadcast message bit sequence 2600 betwixt.Along with time sequencing ground shows a plurality of squares, each square represents a block of information bits in the sequence 2600.The length of square shows corresponding information bit block size.The filling pattern of square represents bit block and belongs to the subsequence that is associated.Square with different filling patterns is associated from different subsequences.For example, square 2604,2608,2614,2618 all has identical filling pattern with 2624, and all is used for sending the bit of the first subsequence.Square 2606,2616 all has identical filling pattern with 2626, and all is used for sending the bit of the second subsequence.Square 2610 all has identical filling pattern with 2620, and all is used for sending the bit of the 3rd subsequence.Square 2612 all has identical filling pattern with 2622, and all is used for sending the bit of the 4th subsequence.
According to some aspects, the broadcast cycle of a subsequence can be different from the broadcast cycle of another subsequence.For example, the first subsequence can have the cycle shorter than the second subsequence, and the bit block of the first subsequence size is less than the bit block size of the second subsequence.
To pre-determine with fixing mode this sequences segmentation is become a plurality of subsequences, the position of each subsequence pre-determines and fixes in this broadcast message bit sequence.These subsequences are interlaced with one another.In order to allow receiving equipment and this sequence synchronous, in an example, this sequence has certain structure (for example, numbering/timing architecture), with the position of indication subsequence.For example, be similar to example more early, can pass on the numbering structure by beacon symbols entrained in the beacon burst sequence.In another example, a subsequence (for example, the 4th subsequence among Figure 26) is the parity check of all other subsequences.For example, square 2622 comprises the Parity Check Bits in square 2614,2616,2618 and 2620 the formerly square of comprising of every other subsequence..Subsequently, receiving equipment can use this coding structure, and moves the Moving Window search with the position of detection parity square, thereby determines synchronization structure.
The broadcast message collection comprises a plurality of subsets.Use specific subsequence to send each broadcast message subset.Subsequence can have its oneself form, so that the bit that transmits in this subsequence is made an explanation.Different subsequences can be used different forms.According to some aspects, following being explained in more detail, subsequence can use synchronous form or asynchronous form.A sequence can comprise multiple synchronization subsequence and one or more asynchronous subsequence.According to an example, only there is an asynchronous subsequence in this sequence.
Synchronously the form of subsequence the explanation of the information bit that transmits in this subsequence (for example, to) is to carry out predetermined according to the position in this subsequence.Therefore, how do not need message header to indicate makes an explanation to bit.Figure 27 shows the example of the synchronous subsequence 2700 of realizing according to disclosed aspect.
The 2702 representative times of transverse axis.Square 2704,2708 and 2712 can the transmission information relevant with version number and transmitted power.Version number can be software publishing version number, and can be used for the compatibility between definite service station and the mobile device.Transmitted power can be current transmitted power and the maximum power capabilities in service station.Square 2706 can the transmission information relevant with spectrum allocation may and COS.It is FDD or TDD etc. that spectrum allocation may information can be indicated frequency spectrum, and can comprise specified spectrum of carrier or specified downlink carrier and the frequency distance between the uplink carrier in the FDD system.COS can be traditional cellular service, reciprocity ad-hoc network service, cognitive radio service etc.Square 2710 can the transmission information relevant with the technology of supporting with spectrum allocation may.The technology indication air interface technologies (for example, CDMA, OFDMA, GSM etc.) of supporting.Should be noted that because in the precalculated position of subsequence, send version number information, so do not need to add the information head.
