In addition, but the various aspects of describing herein or the programming of feature Application standard and/or engineering are implemented as method, device or manufacture.Being intended to contain such as the term " manufacture " that uses in this article can be from the computer program of any computer readable device, carrier wave or medium access.For example, computer-readable medium (for example can include but not limited to magnetic storage apparatus (such as hard disk, floppy disk, magnetic stripe etc.), CD, compact disk (CD), digital versatile disc (DVD) etc.), smart card and flash memory device (for example, EPROM, memory card, memory stick, key drive etc.).In addition, the various storage mediums of describing herein can represent one or more equipment and/or the other machines computer-readable recording medium for storage information.The various other medias that term " machine readable media " can include but not limited to wireless channel and can store, comprises and/or carry instruction and/or data.
Referring now to Fig. 1, show the wireless communication system 100 of the various aspects that present according to this paper.System 100 can comprise in one or more sectors 106,108 each other and/or about wireless communication signals such as one or more mobile devices 110,112 receptions, emission, relayings and one or more base stations 102,104 of service are provided.Base station 102,104 can be connected to infrastructure network (for example, the internet), and therefore the connectivity to the internet is provided.According to some aspects, peer-to-peer communications service (that for example, directly carries out communicates by letter) can be convenient in base station 102,104 between mobile device 110 and 112.
As one skilled in the art will be able to understand, each base station 102,104 can comprise transmitter chain and receiver chain, its can and then comprise separately transmit and receive with signal a plurality of assemblies of being associated (for example, processor, modulator, multiplexer, demodulator, demultiplexer, antenna ...).Base station 102,104 can also can be gone up from mobile device 110,112 reception information at reverse link (up link) to mobile device 110,112 transmission information on forward link (down link).
In order to make mobile device 110,112 access base stations 102,104 service that provides also is provided or utilize frequency spectrum to carry out peer-to-peer communications, specific system information is broadcasted in base station 102,104.According to some aspects, this broadcast message collection can be divided into one or more subsets.Some subsets can be broadcasted termly according to predetermined broadcast cycle in base station 102,104, and different subset can be associated from different broadcast cycle.According to some aspects, some subset can be broadcasted with the common message Signalling method in base station 102,104, thus this broadcast scheduling be not be scheduled to or be not (for example, optionally change) of fixing.
For example, the first broadcast message subset may be relevant with the basic configuration of system 100 so that the ability of connecting system 100 to be provided to mobile device 110,112.Be included in the first broadcast message subset can be one or more (or its combination) in the following: base information, spectrum allocation may information, transmission power information, information on services, communication technology information, system version (compatibility) information, band information, service operator information, system load information etc. during system.This broadcast message tabulation can not change in time and not.Below will provide about being included in other information of the information in the first subset.
The second broadcast message subset may be with to change hand relevant.For example, mobile device 110 may move on to another geographic area 108 from the first geographic area 106, thereby causes the hand that changes 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 is being experienced minimum service disruption (if some words) during a handoff.
System's 100 parameters on the same group can be used not in base station 102,104.For example, in ofdm system, spectral bandwidth is divided into a plurality of frequencies and transfers.In each base station, each is frequently transferred according to specific hopping pattern and jumps.Hopping pattern can be controlled by system parameters, and different base station 102,104 can select different system parameter values with the interference diversity between the base station 102,104.
System parameters allows mobile device 110,112 to move to another base station 104 from a base station 102.It is useful allowing mobile device 110,112 to obtain system parameters rapidly, can alleviate during a handoff service disruption like this.Therefore, the second broadcast message subset can be less than the first broadcast message subset.For example, the second subset can comprise the fix information bit of a small amount of number and broadcast cycle time repeated broadcast that can be relatively short.Should be noted that this is to suppose that mobile radio station 110,112 has been connected to base station 102,104, and has obtained thus at least a portion of the first broadcast message subset when changing hand.
Forward Fig. 2 to, show according to the beacon signal 200 in example OFDM (OFDM) system of each side as herein described.First and second (or more) broadcast message subset can be used a distinctive signal or signaling schemes, and---being called as beacon signal---transmits.
The 202 representative times of transverse axis, and the longitudinal axis 204 represents frequency.File---some of them mark with 206---represents the frequency accent in the given code-element period.Code element is transferred in each little box indicating frequently such as square frame 208 grades, and it is that the single frequency of single transmitted symbol on the cycle transferred.The degree of freedom in the OFDM code element is to transfer code element 208 frequently.
Show four little black box, separately (210) expression one beacon signal code element.The transmitting power of each beacon signal code element than every frequency on the whole time interval 212 transfer the code element average transmit power much higher (for example, high at least approximately 10 or 15dB).Each OFDM code-element period 214,216,218, the 220th, the beacon signal burst.In this diagram, each beacon signal burst comprises the beacon symbols of a transmitted symbol on the cycle.
Fig. 3 shows another beacon signal 300 of one or more uses that can be in disclosed example.Beacon signal 300 is similar with the beacon signal 200 among the upper figure.Difference between these two beacon signals 200,300 is that beacon signal 300 comprises two beacon symbols that identical single frequency is transferred on two continuous code-element periods.Especially, the beacon signal burst comprises two continuous OFDM code-element periods 312,314,316,318.
Fig. 4 shows the another beacon signal 400 of one or more uses that can be in disclosed example.This beacon signal 400 and above beacon signal 200,300 similar.Difference is, comprise may be continuously or may discontinuous two OFDM code-element periods in each beacon signal burst in this beacon signal 400.Yet, in these two OFDM code-element periods, only transmit a beacon symbols.In given beacon signal burst, this beacon symbols may appear in this two cycles any one.For example, show two beacon burst 412 and 414.The beacon symbols of beacon burst 412 appears in the OFDM code-element period, and the beacon symbols of beacon burst 414 appears in the 2nd OFDM code-element period.
For Fig. 2,3 and 4, the time location of beacon burst is scheduled to.For example, in Fig. 2, predetermined beacon burst is arranged in OFDM code element 214,216,218,220.For example, in Fig. 3, predetermined beacon burst is arranged in the OFDM code element to 312,314,316,318.For example, in Fig. 4, predetermined beacon burst is arranged in the OFDM code element to 412 and 414.
Can select the degree of freedom in the predetermined OFDM code element to transmit beacon symbols.For example, in Fig. 2, can select in the OFDM code element 214 any one frequently to transfer code element to come this beacon symbols of signaling, and in Fig. 4, can select the OFDM code element that in 412 any one transferred code element frequently.Therefore, the sum of the degree of freedom of beacon burst is twice among Fig. 2 among Fig. 4.
Fig. 5 shows the example system 500 of being convenient to transmit the independent information subset.System 500 can be used in the cordless communication network to allow mobile device to communicate with one another and/or and base station communication.System 500 can be convenient to convey a message in the mode of the change that first information subset is made (or more) information subset that can not affect second.The different encoding schemes (for example, independently coding/decoding) that therefore, two kinds of mutually noninterferes can be arranged.Comprise the one or more transmitters 502 that transmit information to one or more receivers 504 in the system.Transmitter 502 and/or receiver 504 can be base station, mobile device or other system components that conveys a message.
First information stream maker 506 can determine to use which subgroup or which piece based on the information that will carry in signal, for example this signal can comprise the information relevant with peer-to-peer communications and/or the relevant information with cellular communication.This information can be by encoding to process (for example, coded-bit).This coded-bit can have any value in " 0 " or " 1 ", and the transmission location of this bit can be based in part on this bit value (" 0 " or " 1 ").
The expression of broadcast singal 600 has been shown among Fig. 6.Broadcast singal 600 is the subdivisions with above beacon symbols 200,300,400 similar beacon symbols.Should be appreciated that, broadcast singal 600 only is used as example, and also can use with disclosed each side other broadcast symbol.Time is along transverse axis 602 expressions, and frequency is along the longitudinal axis 604 expressions.This example beacon symbols 600 comprises having separately two code-element periods 606,608 that 4 frequencies are transferred code element, is total up to 8 frequencies and transfers code element or the degree of freedom.
Total degree of freedom in two code-element periods 606,608 of broadcast singal 600 (such as by first information stream maker 506) is divided into the first bandwidth subset 610 and the second bandwidth subset 612.For example, frequently transfer code element 0,1,2 and 3 can be arranged in the first bandwidth subset or first 610, and transfer code element 4,5,6 and 7 can be arranged in the second bandwidth subset or second 612 frequently.Should be appreciated that, also can utilize the frequency of other configurations and other numbers to transfer block of symbols, and show a kind of simple scheme here.Selected frequency adjustable block 610,612 can transfer the code element subregion similar with the fixedly frequency that does not change with the beacon signal burst.Can use identical partitions to each piece, become in the time of perhaps may between each piece, having some according to some aspects.
In given beacon signal burst, used frequency transfers block of symbols or subset to convey a message, and this can be called as information bit or piece encoding scheme { b
1.Which piece encoding scheme { b first information stream maker 506 can be configured to 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 frequency is transferred block of symbols.In addition, between two bandwidth subsets, may there be some frequently to transfer code element not to be used.One of them reason is in order to alleviate mobile device the frequency in the bandwidth subset to be transferred another situation of frequently transferring code element to make a mistake in code element and another bandwidth subset, because base and Frequency Synchronization during hidden hunger between service station and the mobile device.In another example (not shown), bandwidth is divided so that the degree of freedom of each bandwidth subset is interlaced with one another, and the bandwidth subset may not be that continuous frequency is transferred block of symbols in this case.
Should be realized that, first information stream maker 506 can be determined bandwidth subset subregion in other sights.For example, if beacon burst comprises two OFDM code elements as illustrated in fig. 4, then the total degree of freedom in these two OFDM code elements can be divided into a plurality of bandwidth subsets.Some bandwidth subsets can comprise the degree of freedom in the OFDM code element, and another bandwidth subset can comprise the degree of freedom in the 2nd OFDM code element.
In given beacon burst, convey a message in order to the degree of freedom that transmits broadcast symbol, this can be called as information bit or encoding scheme { c
i.Which subgroup is the second information flow maker 508 selected specific degrees of freedom select independent or irrespectively definite with first information stream maker 506.For example, the second information flow maker 508 can be chosen certain tones accent code element (or the encoding scheme { c in the subgroup
1), and first information stream maker 506 can be selected actual frequency accent by selecting specific subgroup (or piece encoding scheme { b1}).Piece encoding scheme { the b of first information stream maker 506
1Selection and the encoding scheme { c that selects of the second information flow maker 508
1Can any order occur, because these two selections are independent of each other.
For example, first information stream maker 506 can flow { b for the first information
1Select and comprise and frequently transfer code element 0,1, the first subgroup 610 of 2 and 3, and the second information flow maker 508 can be for the second information flow { c
1Select and frequently transfer 2.Yet, transfer code element 4,5, the second subgroup 612 of 6 and 7 frequently if first information stream maker 506 is chosen to comprise, and the second information flow maker 508 chooses identical frequency and transfers element position, transferring code element frequently will be to transfer code element 6 frequently now.This is because transfer code element 6 frequently and frequently transfer the position of code element 2 identical (but in different subgroup 610,612), and the second information flow maker 508 does not consider first information stream maker 506 has been chosen which subgroup 610,612.
The second information flow maker 508 can utilize various algorithm, method and/or technology be used to choosing encoding scheme to be based in part on encoding scheme { c
1Choose and transfer the position of code element in subgroup frequently.The employed actual code element of frequently transferring is because becoming in first information stream maker 506 selected piece, specific { c
1Sequence and jump sequence.Therefore, depend on first information stream maker 506 has been chosen which subgroup 610,612, and it can be 0 or 4 that the frequency in this example is transferred code element; 1 or 5; 2 or 6; Perhaps 3 or 7.Because encoding scheme { b
1And { c
1Independently, so if wherein any one encoding scheme changes, then can not affect another encoding scheme.
Illustrated among Fig. 7 from the visual representation of the example codes scheme of the angle of the second information flow maker 508.Encoding scheme { c
1Base scheme when providing a kind of, and a kind of method for jumping, repeat etc. can be provided.Encoding scheme { c
1In time (or on other intervals) repetition, this time or interval can be very little intervals.
Time is along transverse axis 702 expressions, and frequency is along the longitudinal axis 604 expressions.Show three different beacon symbols 708,710 and 712 at the top of 702 these figure of place.Each beacon symbols 708,710,712 the first half are the first subgroups, and Lower Half is the second subgroup---be represented as respectively 714 and 716, the beacon symbols 600 shown in they and the upper figure is similar.As shown in the figure, first information stream maker 506 can flow { b for the first information
1Choose the second subgroup, the first subgroup of beacon signal 710 and second subgroup of beacon signal 712 of beacon signal 708.The second information flow maker 508 can be for the second information flow { c
1Chosen position, shown in black box.In selected position, send high energy signals, no matter and the subgroup that first information stream maker 506 is chosen how.In this example, the cycle only is the 3 and second information flow { c
1Can repeat.First information stream { b
1Can have diverse periodicity.In other words, the second information flow { c
1The actual block that is positioned at is because becoming in first information stream { b
1, yet from the second information flow { c
1Angle, encoding scheme does not change (because the second information flow { c
1And be indifferent in which piece send high energy signals).The time basic information that can be used to the decoded information bit periodically is provided.After observing some sequences, can determine starting point and end point, they can provide a certain assurance of this piece Nei Shiji.Out of Memory about time base information below will be provided.
Secondly, the second information flow maker 508 is not related to and also need not to know the selected specific subgroup of first information stream maker 506.This is because the second information flow maker 508 only is concerned about frequently transfers element position and be indifferent to frequency and transfer code element may be positioned at wherein group.
According to some aspects, information scheme { b

Figure 13 shows when with relatively short broadcast cycle time example beacon signal during repeated broadcast the second broadcast message subset.The 1302 representative times of horizontal line, and ordinate 1304 represents frequency.In this example, in beacon burst, the degree of freedom is divided into two bandwidth subsets: index (for example, { X
i) be subset 1306 and index (for example, { X of " 0 "
i) be the subset 1308 of " 1 ".Each bandwidth subset 1306,1308 in this example comprises 8 frequencies and transfers code element, and relative indexing (for example, { Y
i) be 0,1 from top to bottom ... 7.
The second information bit sequence corresponding to the second subset 1308 comprises fixing and limited sets of bits, and this sets of bits is repeated once to send by per three continuous beacon burst.For example, the second information bit collection is determined three relative indexing (for example, { Y
i) r1, r2 and r3.In beacon burst 1310, r1 is used to determine the relative indexing (in this example relative indexing=3) of beacon symbols, shown in 1312.In beacon burst 1314, r2 is used to determine the relative indexing (in this example relative indexing=5) of beacon symbols, shown in 1316.In beacon burst 1318, r3 is used to determine the relative indexing (in this example relative indexing=6) of beacon symbols, shown in 1320.This pattern repeats in time: in beacon burst 1322, r1 is used to determine the relative indexing (in this example relative indexing=3) of beacon symbols, shown in 1324.In beacon burst 1326, r2 is used to determine the relative indexing (in this example relative indexing=5) of beacon symbols, shown in 1328.In beacon burst 1330, r3 is used to determine the relative indexing (in this example relative indexing=6) of beacon symbols, 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 bandwidth subset index sequence (for example, { X
i) m1, m2, m3, m4, m5, m6 etc.In beacon burst 1310, m1 is used to determine the index (in this example subset index=0) of bandwidth subset.In beacon burst 1314, m2 is used to determine the index (in this example subset index=0) of bandwidth subset.In beacon burst 1318, m3 is used to determine the index (in this example subset index=1) of bandwidth subset.In beacon burst 1322, m4 is used to determine the index (in this example subset index=1) of bandwidth subset.In beacon burst 1326, m5 is used to determine the index (in this example subset index=0) of bandwidth subset.In beacon burst 1330, m6 is used to determine the index (in this example subset index=0) of bandwidth subset.Although note relative indexing r1, r2, r3 repeats with short broadcast cycle, subset index m1, m2 ... broadcast cycle that can be much longer repeats or does not repeat.
In the example of the system that uses approximate 1.25MHz bandwidth, total bandwidth is divided into 113 and frequently transfers.Beacon burst comprises one or more OFDM code-element periods.In beacon burst, these are frequently transferred and are divided into two or three bandwidth subsets, comprise that separately 37 frequencies in the given OFDM code-element period are transferred code element (for example, M=2 or 3, and K=37).Per 18 the continuous beacon burst of relative indexing repeat once.
Though perhaps not shown, the first broadcast message subset pass on relative indexing and the second broadcast message subset dedicated bandwidth subset index to pass on also be possible.
Referring now to Figure 14, show a kind of exemplary method 1400 that in broadcast singal, transmits the broadcast message sets of bits of realizing according to disclosed each side.Although explain the method diagram of oversimplifying in specifically describing and be described as a series of actions for making, but be to be understood that and understand that the order that these method collection are not moved limits, because according to one or more aspects, some actions can by different order occur and/or with occur concomitantly from other actions that illustrate herein and describe.For example, those skilled in the art it will be appreciated that and understand, and the method collection can be expressed as a series of state or events of being mutually related with being replaced, just as in the state diagram.In addition, be not all illustrative actions are all realize necessary according to the method collection of one or more aspects.
In given beacon burst, beacon symbols can be passed on the first and second broadcast message subsets with the degree of freedom in the middle of the degree of freedom with all.The selected degree of freedom belongs in the bandwidth subset.In given beacon burst, the first broadcast message subset is encoded to choose this beacon signal (for example will use for which bandwidth subset, and the second broadcast message subset is encoded to determine this beacon signal will be used which degree of freedom in the selected bandwidth subset piece).
The first broadcast message subset can be represented by first information bit sequence, and the second broadcast message subset can be represented by the second information bit sequence.The first subset can relate to basic configuration, and it can comprise for how to determine the spectrum disposition information of special frequency band for peer communications devices.Frequency band can be identical or different with the frequency band that sends therein this broadcast message.Spectrum disposition information can indicate this special frequency band of peer communications devices whether can be used to peer-to-peer communications, and if can then indicate the power budget that transmits for peer-to-peer communications.The second subset for example can be with to change hand relevant.According to some aspects, the second 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.
1406, choose a subset in two or more at least bandwidth degree of freedom subsets of broadcast message bit because becoming in the first broadcast message bit subset.Each subgroup may be continuously or away from each other.According to some aspects, the first and second broadcast message bit subset are the subsets of separating in the broadcast message sets of bits.Each subgroup can be divided into a plurality of subsets or the degree of freedom.Frequently each the bandwidth degree of freedom in transferring can be an OFDM code element.
1408, in selected subset, select in the bandwidth degree of freedom at least one because becoming in the second broadcast message bit subset.1408, this beacon signal of emission during selected bandwidth degree of freedom subset.According to some aspects, beacon signal can be launched substantially simultaneously with other signals.For example, beacon signal can with other signal overlaps.Compare with other beacon signal, this beacon signal can the high-energy emission.This beacon signal can comprise the piece sequence that occurs by the time.
The control information that according to some aspects, at least one in these two or more broadcast message bit subset comprise and will be received by wireless device be used for peer-to-peer communications---wherein wireless device directly and another wireless device communication---.This control information can comprise one or more in the following: frequency band allocation information; Whether peer-to-peer communications is allowed in this frequency band; The control wireless device is used for the control parameter of the maximum transmission power of peer-to-peer communications; Or its combination.
1402 determine to use in two or more bandwidth subsets which and determine that 1404 which degree of freedom in the selected bandwidth subset is used for transmitting this beacon symbols and can carries out independently.Purpose presented for purpose of illustration and not limitation, the available frequency in the given beacon burst is transferred code element absolute indices a=0, and 1 ..., the N-1 numbering, wherein N is the integer of the available frequency accent of expression code element sum.In each bandwidth subset, frequently transfer code element relative indexing r=0,1 ..., K numbers, and wherein K is that each bandwidth subset intermediate frequency of expression is transferred the integer of number of symbols.In this example, the number of each bandwidth subset intermediate frequency accent code element is identical.In addition, first of each bandwidth subset the absolute indices of frequently transferring code element (for example, its relative indexing equal 0 frequency transfer code element) is by s=s
0, s
1..., s
M-1Provide, wherein M is the integer of the number of expression bandwidth subset.Therefore, transfer code element for given frequency, absolute indices (a) transfers index (m) and the relative indexing (r) of the affiliated bandwidth subset of code element relevant with this frequently, and its relation is as follows:
A=s
m+ r formula 4
1402, the index of bandwidth subset (m) can be determined by the information sequence of the first broadcast message subset.1404, relative indexing (r) can be determined by the information sequence of the second broadcast message subset.Should be noted that the determining and the determining and to carry out independently r at 1404 places m at 1402 places.According to m and r, calculate absolute indices (a) at 1408 places for beacon symbols.From a beacon burst to another beacon burst, beacon symbols can use different bandwidth subsets, because determine m with the different piece of information sequence.
The Code And Decode of the first and second broadcast message subsets can be carried out independently according to disclosed each side.For example, when the encoding scheme of the first broadcast message subset changed, on the not impact of Code And Decode of the second broadcast message subset, vice versa.In addition, because the m temporal evolution so beacon symbols comes from the different bandwidth subset, has strengthened diversity thus.
Figure 15 shows according to the exemplary method 1500 of each side from two broadcast message subsets of beacon signal decoding.This beacon symbols can comprise the piece sequence that occurs by the time.Method 1500 begins in 1502 receptions of sentencing signal in time cycle of beacon burst.Receive signal than other, this signal can receive by high-energy.In addition, this signal can be substantially and other signal receive simultaneously.The degree of freedom of launching therein this beacon symbols can be determined when receiving signal substantially.In order to determine this degree of freedom, utilize every degree of freedom transmitting power of beacon symbols far above this fact of mean value.
1504, determine this beacon symbols belongs to which (for example, the receiving therein beacon symbols) in predetermined a plurality of bandwidth subsets.In 1506 degrees of freedom of determining to receive therein in the selected bandwidth subset of this beacon signal.1504 and 1506 result can be used to respectively reconstruct the first and second broadcast message subsets.The first subset can relate to basic configuration, and the second subset can relate to and changes hand.
Should be noted that 1504 determine these beacon symbols belong in predetermined a plurality of bandwidth subsets which and can carry out independently in 1506 degrees of freedom of determining to transmit therein in the selected bandwidth subset of this beacon symbols.Continue the example of Figure 14, detect the absolute indices (a) of receiving beacon symbols.Because the bandwidth subset is separated in this example, so index m and r can derive uniquely from a.In case be scheduled to the bandwidth subset, then the definite of m just depended on which bandwidth subset is this absolute indices (a) drop on and also have nothing to do thus with to the definite of r.
Figure 16 shows the exemplary method 1600 of operation base station.Method 1600 begins at 1602 places, and wherein the first value is assigned to first information stream.First information stream can represent the first broadcast message subset.The first value is assigned to first information stream can be comprised a plurality of information bit { c

1606, can first information stream is combined with the second information flow.This combination allows when needed, and two information flows are sent out substantially simultaneously.Yet the value of each stream is that difference is worked as and independent the derivation.With the combined available equation (Z of the first and second information flows
i={ X
i* Q+{Y
i) calculate.In this equation, { Y
iExpression is assigned to the first value of first information stream, { X
iExpression is assigned to the second value of the second information flow, and Q represents the maximum of first information stream.This combined information stream can create the broadcast singal that occupies the space larger than the space of the space of first information stream and the second information flow.
1608, this combined value or composite value generate composite value.1610, because becoming in this composite value transmitted waveform.Waveform can comprise the high-energy beacon symbols.The beacon symbols transmitting power of every degree of freedom can be than the high at least 10dB of transmitting power in order to send other signals.Waveform can occupy small freedom of motion.Target recipient can receive this waveform and this composite value is separated into its subcomponent (for example, first information stream and the second information flow).Figure 17 shows the exemplary method 1700 of being convenient to explain waveform received in communication.This waveform represents and can receive from the transmitter that utilizes the method 1600 of discussing with reference to upper figure.
When receiving the high-energy beacon signal that is included in the waveform, method 1700 begins at 1702 places.This receives that signal can comprise the combination of the first value and the second value.The combination of this first value and the second value comprises the broadcast singal that occupies the space larger than the space of the space of first information stream and the second information flow.This signal can high-energy receives and/or can occupy small freedom of motion.Additionally or alternatively, this signal can be substantially and other signal receive simultaneously.
Basic when receiving waveform, this wave analysis is become at least two subcomponents or value.1704, identify the first value of first information stream, and 1706, 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.Definite and the sign of stream can be carried out independently and with any order ground.Therefore, if the coding of a stream and/or decoding change, then it does not affect coding and/or the decoding of another stream.

The frequency that Figure 18 shows in code-element set service time is assembled the exemplary method 1800 of the information that transmits.May be desirably in the different information subset of transmission between single transmission period.Different information subset can be sent to identical or different recipient, and this depends on information butt joint debit's applicability (for example, system parameter message, change hand information etc.).Method 1800 allows to revise one or more subcomponents of the information that transmit and other subcomponents that can not affect information.
1802, at least some frequently are in harmonious proportion some time code elements and are designated as piece.Piece can comprise that the frequency that timing code unit concentrates assembles.Transmit the time period of information during this piece can be illustrated in and can repeat in time.1804, piece can be divided into two or more subgroups.Each subgroup can comprise the frequency tune collection in the time symbol subset.Each subgroup can represent first information stream (for example, { b
1).Each subgroup can be adjacent one another are or separately.1806, these two or more subgroups are divided into several microliths.Each microlith can comprise that in the time code element at least one transfer frequently.Each microlith can represent the second information flow (for example, { c
1).Each microlith need not evenly to separate.Mapping can be based on the first and second information flows, and can be mutual exclusions in frequency with on the time.That is, change an information flow and do not affect another information flow.Therefore, change base (for example, microlith) or the change of the second subcomponent in the time of can't causing of frequency or the first subcomponent (for example, subgroup).
1808, (for example, the degree of freedom) in one of these two or more subgroups in the microlith is selected for information and transmits.The selection of subgroup and the selection of microlith represent to be included in the information in the information of transmission.Subgroup can be selected because becoming in first information stream, and microlith can be selected because becoming in the second information flow.In selected microlith, this information transmits with high-energy than non-selected microlith.
Figure 19 shows for explanation and shows the exemplary method of receiving signal 1900 that the concentrated frequency of timing code unit is assembled.1902, receiving broadcasting information.This broadcast message receives in the microlith of selecting from piece, and this microlith can comprise the one or more frequencies accent in the time code element.Broadcast message can comprise the two or more information subset that are combined to send individual signals (for example, microlith).The positional representation of this information in signal should be decoded in order to fully understand the information that this receives signal by the recipient of information.This information of decoding relates to 1904 determines the subgroup under this microlith and the piece that comprises this subgroup in 1906 signs from least two subgroups.This piece can comprise that the frequency that timing code unit concentrates assembles.Subgroup can represent first information stream or can select because becoming in it, and microlith can represent the second information flow or can select because becoming in it.Being mapped in frequency and being mutual exclusion on the time based on the first and second information flows.Definite reception and registration of this subgroup and microlith is included in the information in institute's transmission information.The decoding of first information stream can be carried out in the situation of the decoding that does not affect the second information flow.
According to some aspects, in given beacon burst, which degree of freedom is used to transmit beacon symbols and conveys a message.In fact each beacon burst sends the information code element that its value equals an element in the reserved word matrix.Supposing has K the degree of freedom can be for beacon signal in the beacon burst, and the degree of freedom is indexed as 1 ..., K-1.In an example, alphabet is given as 0,1 ..., K-1: the value of this information code element equals the index of the used degree of freedom of beacon symbols.In this case, alphabetic(al) size equals K.In another example, alphabetic(al) large I is less than the number of the degree of freedom in the beacon burst.For example, alphabet is given as 0 and 1: information code element can equal 0 at the index of the used degree of freedom of beacon symbols in less than the situation of floor (K/2).In another example, alphabet is given as 0 and 1: information code element is can equal 0 in the situation of even number at the index of the used degree of freedom of beacon symbols, otherwise equals 1.
Expression N is alphabetic(al) size.In an example, the information code element in the single beacon burst can be used to send the broadcast message bit of fixed integer number.For example, if N=2, then information code element can be used to send 1 bit.In another example,---can be continuous---can be used to send a fixed integer number broadcast message bit to a predetermined number information code element.For example, if N=3, then two information code elements can be combined 9 different values of signaling.Eight in these values are used to send three bits, so that last value is kept.Therefore, the beacon burst sequence can be passed on the broadcast message bit sequence.
According to some examples, beacon burst can periodically be numbered.For example, refer again to Fig. 2, beacon burst 214 is numbered as 0.Beacon burst 216 is numbered as 1, and beacon burst 218 is numbered as 2.Then, numbering repeats: beacon burst 220 is encoded as 0, by that analogy.This numbering structure can be come signaling by the beacon symbols that is carried in the beacon burst sequence.
For example, consider that wherein alphabet is given as Fig. 2 of 0 and 1: information code element can equal 0 at the index of the used degree of freedom of beacon symbols in less than the situation of floor (K/2), otherwise equals 1, and wherein K is the number of the degree of freedom.In fact, signaling schemes is divided into two bandwidth subsets with the degree of freedom: its index is less than the bandwidth subset and the bandwidth subset of its index more than or equal to (K/2) of floor (K/2).In beacon burst, information code element is to come signaling by the selection to the bandwidth subset that is used for beacon symbols.Simultaneously, the degree of freedom under the bandwidth subset can be come index with relative indexing, and relative indexing can be in each beacon burst signaling.In the interval of some beacon burst, the sequence of relative indexing can be used to provide and comprise the additional information of numbering structure.
Numbering structure actual is synchronization structure, and should be used in this example, and wherein predetermined a plurality of information code elements can be used to send the broadcast message bit of fixed integer number.In this case, the numbering structure helps to determine which information code element should use to determine the broadcast message bit together.For example, in Fig. 2, the alphabet size of supposing information code element in each beacon burst is 3.Beacon burst 214 and 216 information code element can be united 3 bits of signaling, and the information code element of beacon burst 218 and 220 can be united 3 other bits of signaling.The numbering structure helps sign marshalling 214 and 216 so that receiving equipment can not made mistakes because being grouped in together 216 and 218.
According to some aspects, the numbering structure can be only derives from the sequence of the information code element of observing in time.For example, in above example, the alphabet size of information code element is 3, but and so 9 different values of a pair of information code element signaling.Eight in these values are used to 3 bits of signaling, and last value is retained or does not use.Receiving equipment can utilize above structure " blind " to derive the numbering structure.Particularly, receiving equipment can be supposed the first numbering structure and check to (214,216), (218,220) etc., and does not have a pair of value that is retained that will have, and receiving equipment can judge that the numbering structure of supposing is correct accordingly.On the other hand, receiving equipment also can be supposed the right of the second numbering structure and inspection (216 and 218), etc., and randomly, more possible to having the value that is retained, receiving equipment can judge that the numbering structure of supposing is incorrect accordingly.
Usually, exist two or more information flow available broadcast signals to transmit.First-classly usually used by most of cellular networks, and comprise some parameters, determine the out of Memory of base station identity such as cellular cell sign, sector mark, transmitting power, access power and help mobile device.This is first-class to comprise that mobile device is used for determining when and answers access base station, when should carry out the parameter of changing hand etc.
The second information flow or type can be the information of supporting cellular application and non-cellular application.For example, have a licensed spectrum, but also may wish to allow peer-to-peer network, wherein specific mobile device can be carried out self-organizing and communicate by letter to alleviate workload by the base station.Yet, and allow mobile device to set up at random the challenge that such communication is associated to be that the service supplier may not have ownership for hope at frequency spectrum that its place sets up communication.For example, the service supplier that registers of equipment may have ownership and the frequency spectrum of West Coast may not had ownership to the frequency spectrum of east coast.The service supplier who has a frequency spectrum of West Coast will not wish that unregistered equipment communicates by letter in its frequency spectrum.Therefore, equipment need to be from local service offerings merchant's information before can setting up communication.
In another example, may exist now the frequency spectrum and the equipment that are not used can set up peer-to-peer communications.Yet in from now on several years, infrastructure will be built to and the owner (for example, service supplier) of this infrastructure (for example, frequency spectrum) will no longer permit peer-to-peer communications.Therefore, the service supplier will wish to set up the control relevant with how using frequency spectrum.Therefore, obtain this information before mobile device Ying Zaiqi launches in these positions.
---it can be called as progressive information---can be placed in the second according to some aspects, to relate to information how to use frequency spectrum, because first-class Ultra-Mobile Broadband (UMB) information that is used to.Progressive information may not be very urgent, and the time that mobile device is monitored is longer, and the amount of information that receives will be larger.
First or second in any one can be with a kind of coding the in previous described two kinds of encoding schemes.For example, the first-class bit { b that is encoded as
i, and second can be encoded as information bit { c
i.Alternatively, second can be encoded as bit { b
i, and the first-class information bit { c that is encoded as
i.
Referring now to Figure 20, show the part of the broadcast 2000 of base when comprising (for example, synchronous) information.Time is illustrated as along transverse axis 2002.Conceptive, broadcast 2000 is information bit { b
iStream.In piece 2004, b1 is transmitted; B2 transmits in piece 2006 and b3 transmits in piece 2008.In order to pass on time base information, piece 2004,2006,2008 should have a pattern (for example, time-base diagram case) or numbering to allow receiving equipment to explain this message with exact sequence.
For example, if broadcast begins with piece b12004, the thing that then may have some in piece b22006, to broadcast.This can carry out with numbering mechanism, and this numbering mechanism can be found in several ways, if such as { c
iHave specific period, but then find out { the c of linear broadcast
i.In case { c
iDecoded and find periodically basis when then it can be used to.According to some aspects, { c
iOn the information of carrying can be used to seek numbering mechanism.
In another example shown in Figure 21, { b
iCan be used to determine starting point.For example, may carry 3 ranks at every turn.Time represents along transverse axis 2102, and has three information bits 2104,2106 and 2108.Each piece in the information bit can transmit 1,2 or 3 (for example, three ranks). Information bit 2104,2106,2108 can gather 9 ranks of signaling (0 to 8).Last rank " 8 " can be retained or not use, and perhaps can be used for carry information but not time base.
Transmit leg adds another rank with the 4th bit 2110 and caused problem, because can be selected any bit combination (for example, 2104 and 2106; 2106 and 2108; 2108 and 2110), and which bit the recipient may not know to have received.Yet according to this example, bit 2108 should not be used, because it carries bit number 8, and this should not be used.Therefore, if chosen wrong combination (for example, 2106 and 2108), then receiver might will be seen bit 8, because its value of being coding.If receiver is found bit 8, base misalignment when then it is indicated, based structures when this provides a kind of (for example, owing to 8 quilts are not inferred and should be existed, this is a mistake).
Base in order to determine, base information and bit stream when receiver will obtain, the example that mark or designator can be provided shown in Figure 22.This allows its place of definition can exist synchronously or the phase structure of asynchronous message.For example, the first two bit after the mark 2202,2204 carries certain synchronization message (for example, position itself provides about how explaining the information of this message).This synchronization message not necessarily has a message, and this position itself is exactly message.The remainder of message (for example, bit) can be taken as asynchronous message together, obtains header/main body/message thereby they can be bonded together.Starting point and end point can not necessarily be determined by location or position by message format.
It is longer that receiving equipment is monitored duration of this message, and it just will receive more bits.In synchronization message, many group synchronization messages may be arranged, other message repeat with different time some of them message with the special time repetition.An example message shows this point among Figure 23, wherein message " A " repeats (illustrating at 2302,2304,2306 places) very continually, and message " B " has different periodicity (illustrating at 2308,2310 and 2312,2314 places respectively) with " C ".Therefore, because position itself becomes with the time base of definition to the explanation of bit, so different synchronization messages may have different periodicity.
Message can comprise about frequency spectrum will how to use, whether equipment be allowed to use the information of this frequency spectrum and/or the particular message of out of Memory or its combination.For example, if message is broadcasted in frequency spectrum " 1 ", then whether message need not this frequency spectrum of suggestion and can use, its only indicating equipment can use frequency spectrum " 2 ", its intermediate frequency spectrum " 2 " is impregnable waveform.Therefore, message need not to relate to the frequency spectrum that broadcast is broadcasted just therein, and can relate to operational other frequency spectrums.Receiving equipment can be monitored the specific part of this message and make the decision-making of using another available frequency spectrum.Indicate the message of the use of current or another frequency spectrum can be arranged in synchronization message or be positioned at 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 to one or more transmitters 2402 of one or more receiver 2404 broadcast messages.Broadcast scheduling can be determined and change to transmitter 2402.For example, transmitter 2402 comparable other message are broadcasted some message more continually, and/or some message are only broadcasted once or several times and afterwards no longer repetition.
Transmitter can comprise reorganizer 2406, and it can be configured to define one or more subsequences of broadcast message bit and determine the structure of the one or more subsequence in broadcast.This structure can be defined as the position of each subsequence in this broadcast.Location positioning can be predefined.
This sequence can have ad hoc structure (for example, numbering/time based structures), and this structure can be configured to indicate location or the position of each subsequence in broadcast or signal by getter 2408.The broadcast message collection can comprise a plurality of subsets, and wherein each broadcast message subset uses specific subsequence to send by broadcasting equipment 2410.According to some aspects, each subsequence can be interlaced with one another together.
Being included in two or more subsequences in the broadcast singal can have different periodicity or can be interlaced with one another together.According to some aspects, the broadcast cycle of subsequence is 1 second at least, and a broadcast cycle is transmitted with connecing a broadcast cycle.In addition or alternatively, broadcast singal comprises the information used about frequency spectrum, allows to use information or its combination of the equipment of frequency spectrum.
Referring now to Fig. 5, show the example system 2500 that comprises the broadcast singal of a plurality of subsequences for explanation.Transmitter 2502 can be configured to broadcast the information that will be sent to receiver 2504.Broadcast message can comprise that a plurality of subsequences maybe can comprise single subsequence.In order to explain subsequence, base locator 2506, message header definition device 2508 and evaluator 2510 when receiver 2504 can comprise.
According to some aspects, the form of some subsequences is not so that the position in subsequence and predetermined.The information bit of passing in the subsequence can belong to different broadcasts, and these broadcasts are not predetermined or fixing.Each message can comprise at least one in message header and the source body.Therefore, message can asynchronous system sends and this subsequence can be called as asynchronous subsequence.Message header definition device 2508 can be configured to estimate broadcast singal (or be included in the broadcast singal subsequence) to define header.
According to some aspects, synchronous and asynchronous can coexist in the broadcast message sequence.In Short Interval, receiver 2504 should be able to obtain the necessary broadcast message of access transmitter (for example, service station) from beacon signal.As time goes by, receiver 2504 can receive increasing beacon burst and can accumulate increasing broadcast message bit.
Based on information received and that explained by defined message header at least in part, evaluator 2510 can be made receiver 2504 and whether should be changed the second frequency spectrum into from the first frequency spectrum, continues to stay current frequency spectrum, change determining of its transmitting power or other parameters etc.
For example, the first mobile device will wish to set up communicate by letter (for example, peer-to-peer communications) with the second mobile device.But serve the base station broadcast of the geographic area at these two mobile device places., broadcast can set up the information of peer-to-peer communications if can comprising indicating equipment use specific frequency spectrum.This can be similar to the message shown in Figure 23 and transmit at channel " A ".The purposes of channel " B " can provide different periodicity.Each mobile device will seek message the time base to determine how to explain these bits.In case through explaining, just can estimate these bits and should use specific frequency spectrum, whether have communication priority or out of Memory determining whether.Available out of Memory is power information, can only use the indication of the power that is lower than threshold level such as (all) mobile devices.Additionally or alternatively, may exist the physical layer that equipment should have/mac layer parameter in order to determine corresponding emission.
Memory 215 also can be preserved and relate to that the location is included in this beginning position of receiving each subsequence in the broadcast singal and at least in part based on locate the to decode instruction of this at least one subsequence of beginning position.Seek the beginning position and can comprise that the location is included in the designator in the beacon signal.The beginning position of synchronization message can convey a message.Memory 2512 also can be preserved and relate at least in part based on the instruction of revising at least one parameter through the message of explaining.
According to some aspects, the broadcast message bit sequence comprises a plurality of sequences.Figure 26 shows the example that realizes according to disclosed each side, broadcast message bit sequence 2600 is divided into a plurality of subsequences.
Transverse axis 2602 is illustrated in the logical time that sends broadcast message bit sequence 2600 therebetween.A plurality of square frames have been shown along time sequencing ground, wherein the block of information bits in each expression sequence 2600.The length of square frame shows corresponding block size.The filling pattern of square frame represents to belong to the bit block of the subsequence that is associated.Square frame with different filling patterns is associated from different subsequences.For example, square frame 2604,2608,2614,2618 and 2624 all has identical filling pattern and is used to send the bit of the first subsequence.Square frame 2606,2616 and 2626 all has identical filling pattern and is used to send the bit of the second subsequence.Square frame 2610 with 2620 both have identical filling pattern and be used to send the bit of the 3rd subsequence.Square frame 2612 with 2622 both have identical filling pattern and be used to send the bit of the 4th subsequence.
According to some aspects, what the broadcast cycle of a subsequence can be from another subsequence is different.For example, the first subsequence has the cycle shorter than the second subsequence, and the block size of the first subsequence is less than the block size of the second subsequence.
Sequence is divided into a plurality of subsequences with predetermined and fixed form, and this is scheduled to and its meaning of fixed form is that the position of each subsequence in the broadcast message bit sequence is predetermined and fixing.Each subsequence is weave in.In order to allow receiving equipment and sequence synchronous, in one example, sequence has the ad hoc structure (for example, numbering/time based structures) of the position of each subsequence of indication.For example be similar to previous example, the numbering structure can be come signaling by the beacon symbols that is carried in the beacon burst sequence.In another example, a subsequence (for example, the 4th subsequence among Figure 26) is the parity check bit of all other subsequences.For example, the parity check bit that square frame 2622 comprises the forwardly frame of all other subsequences---comprising square frame 2614,2616,2618 and 2620---.Then, receiving equipment can utilize this coding structure and move moving window search and come the position of detection parity frame and determine thus synchronization structure.
The broadcast message collection comprises a plurality of subsets.Each broadcast message subset is to use specific subsequence to send.Subsequence can have its oneself form and explain the bit of passing in this subsequence.Different subsequences can be used different forms.According to some aspects, as will more specifically explaining following, subsequence can be used synchronously or asynchronous form.Sequence can comprise various synchronous subsequences and one or more asynchronous subsequence.According to an example, an asynchronous subsequence is only arranged in the sequence.
The form of subsequence (explanation of the information bit of for example, passing in this subsequence) is to be scheduled to because becoming in the position in subsequence synchronously.Therefore, need not message header and indicate how to explain these bits.Figure 27 shows the example of the synchronous subsequence 2700 of realizing according to disclosed each side.
The 2702 representative times of horizontal line. Square frame 2704,2708 and 2712 information that can pass on about version number and transmitting power.Version number can be that software publishing version number and can being used to determines the compatibility between service station and the mobile device.Transmitting power can be current transmit power and the maximum power capability in service station.Square frame 2706 can be passed on the information about spectrum allocation may and COS.Spectrum allocation may information can be indicated frequency spectrum whether FDD, TDD etc., and can comprise frequency or the down link of appointment and the frequency distance between the uplink carrier of designated carrier in the FDD system.COS can be traditional cellular service, reciprocity self-organizing network service, cognitive radio service etc.Square frame 2710 can be passed on about the information of spectrum allocation may with the technology of supporting.The technology indication air interface technologies (for example, CDMA, OFDMA, GSM etc.) of supporting.Should be noted that because the information of version number is to send in the precalculated position of subsequence, so need not to add message header.
In given synchronous subsequence, form can repeat according to the scheduled broadcast cycle.Different information can have different broadcast cycle (for example, because becoming in this information how to be sent to continually receiving equipment).In the example shown, the information of version number or spectrum allocation may repeats once every a square frame, and the service of supporting or the broadcast cycle of the type of skill are then longer.Like this, receiving equipment can obtain the time-critical broadcast message in Short Interval.Then, along with receiving equipment continues to receive beacon burst, receiving equipment can obtain increasing broadcast message, comprises less time-critical information.
The form of asynchronous subsequence be not because of the position that becomes in subsequence predetermined.The information bit of passing in this subsequence can belong to different broadcasts, and can add delimiter to indicate the beginning and end of each message.Figure 28 shows the example of the asynchronous subsequence 2800 of realizing according to disclosed each side.
Time is illustrated as along horizontal line 2802. Square frame 2804,2806 and 2808 is parts of asynchronous subsequence.In this diagram, message starts from the square frame 2804, continues in square frame 2806, and finishes in square frame 2808. Message 2810 and 2812 beginning and end point are by some delimiters definition.Subsequence can be used to send the different messages with different length.The order of strict difinition does not send message.The service station has the freedom of determining and changing broadcast scheduling.Therefore, the appearance of particular message is not to be scheduled to.Each message can comprise at least one in message header and the source body.
Generally speaking, message is sequentially to send with given asynchronous subsequence.According to some aspects, a plurality of asynchronous subsequences are arranged, these subsequences are weave in the broadcast message sequence, can walk abreast in this case to send more than one message.
Figure 29 shows the exemplary method 2900 that transmits the broadcast singal that comprises one or more broadcast message bit sequences.Method 2900 starts from 2902, has wherein defined the one or more broadcast message bit subsequences that are included in the broadcast.2904, determine the positional structure of the one or more subsequence.Determine that positional structure can comprise and determine that the position of each subsequence in broadcast---this position can be predefined.This structure can be defined as numbering or the time in base or its combination at least one.
For the recipient who makes the message that comprises one or more subsequences understands this message, in the position of 2906 indications or the one or more subsequences of mark.According to some aspects, based structures is to indicate the position of one or more subsequences in the time of can determining.The time based structures can be coded in the broadcast singal.
Launch broadcast singal 2908 to the target recipient.Two or more subsequences can be different periodicity send (for example, the first message can be broadcasted more continually than the second message) in broadcast singal.The first message can only be broadcasted several times and afterwards and no longer repeat.The broadcast cycle of one of subsequence can be about 1 second and this subsequence can a broadcast cycle connect a broadcast cycle ground transmission.Two or more subsequences can be interlaced with one another together.
The broadcast message bit sequence can comprise asynchronous message, synchronization message or its combination (for example, at least one asynchronous message and one or more synchronization message are included in this broadcast message bit sequence).Synchronization message can define because becoming in the position of this asynchronous message in broadcast singal.The message header that can comprise the definition that asynchronous message is provided in the asynchronous message.
Figure 30 shows for explanation and receives time base information in the broadcast singal and the exemplary method 300 of related news.3002, receive the broadcast that comprises at least one broadcast message bit subsequence.Subsequence can be about 1 second or the longer time, and can a broadcast cycle receive with connecing a broadcast cycle.Two or more subsequences can be different periodicity received and/or can be interlaced with one another together.
According to some aspects, broadcast singal can comprise at least one asynchronous message or at least one synchronization message or its combination.The definition of one or more synchronization messages can received position in the broadcast singal because becoming in synchronization message.One or more asynchronous messages can comprise the message header of the definition of indicating this asynchronous message.
3004, based on the position that is included in designator in the broadcast singal and determines one or more subsequences.Designator can be specified position or the location of each subsequence in broadcast singal.Can be based in part on this position of determining the one or more broadcast message subsequence of decoding 3006.Also the time based structures that is included in the broadcast singal can be decoded.The time base original position or the location that can be based in part on the one or more subsequence to determine.
Be based in part on and be included in this information in the message of decoding, can change one or more parameters.For example, can make the decision that changes to another frequency spectrum from the first frequency spectrum based on the information that is included in the message.Another example is based on information and revises power, determines to use which frequency spectrum or change other parameters.
According to some aspects, method 300 comprises that also the each several part with broadcast singal is stitched together to derive header/main body/message sequence and/or be based in part on starting point and the end point that message format is determined message.
It will be appreciated that, according to one or more aspects as herein described, can draw an inference about the transmission of broadcast singal and/or explanation etc.As used in this article, term " infer (verb) " or " inferring (noun) " general reference from as via event and/or data capture to one group of process of observing reasoning or inference system, environment and/or user's state.For example, can adopt deduction to identify concrete context or action, maybe can generate the probability distribution on all states.Deduction can be probabilistic---that is the consideration of based on data and event comes calculating probability to distribute on interested state.Infer the technology can also refer to for be combined into higher level event from one group of event and/or data.This type of deduction causes constructing event or the action that makes new advances from the event data of one group of event of observing and/or storage, no matter whether these events are closely related on property meaning around, and also no matter these events and data are from one or several events and data source.
According to example, above-mentioned one or more methods can comprise about being chosen in the degree of freedom that transmits beacon symbols therebetween and drawing an inference.According to another example, can be independent of other information flow ground and make up about being included in information subflow in the broadcast singal/or decoding draw an inference.According to another example, can draw an inference about the one or more subsequences that are included in the broadcast.Can understand, aforesaid example is exemplary and be not to attempt to limit the number of the deduction that each example that associating describes can make or the mode of making this type of deduction herein in essence.
