Abstract

The invention particularly relates to methods for receiving data sent sequentially from a first transmitter (B1) of a mobile radio system on a first resource element (f1) to a receiver (UE), reception gaps occurring during reception. According to said methods, data (b) not received during said reception gaps is reconstructed by the receiver, the data not received from the first transmitter being received in a delayed manner by a second transmitter (B2) on the same resource element between the reception gaps and being used for reconstructing the sequence of data. Implementation is particularly advantageous for carrying out a reception method in the UMTS compression mode process when receiving data that is sent continuously without taking into account the compression mode.

Description

In mobile radio system, have the method that ground, space receives the data that send with sequence that receives

The present invention relates to a kind of preamble feature according to claim 1, in mobile radio system, have a method that ground, space receives the data that send with sequence that receives, relate to the method that in a kind of like this mobile radio system, sends data sequence at least one receiver by transmitter, relate to a kind of receiver, and relate to a kind of communication system preamble feature, that have at least two transmitters according to claim 15 with preamble feature of claim 14.

In mobile radio system, for example in mobile radio system, between the subscriber board (UE:UserEquipment) that moves and base station (Node B), establish a communications link by radio interface according to Universal Mobile Telecommunications System (UMTS) standard.In order to support the mobility of subscriber board, subscriber board must constantly measured aspect the possible switching to another base station (handover).All to carry out such measurement no matter be in idle condition (idle) or in connection status (connected mode connection mode).Therefore (compressedmode compact model/CM) is so that in that (Dedicated Channel dedicated channel/DCH) exists also can carry out that subscriber board alien frequencies (inter frequency) is measured and different radio access technologies (Zwischen-Funkzugriffstechnologie) (Radio AccessTechnology) measurement during connecting under the situation that does not have second receiving system to the channel of being assigned to introduce so-called compression operational mode in UMTS in FDD (frequency division multiplexing) operational mode.Only with a receiving system for example can exist connect during carry out handover measurement to gsm radio access network (the global mobile communication system of GSM:Global System for MobileTeltcommunication).Can be according to current standard by the dissimilar compression operational mode of described network configuration.First operational mode is called " the only up link in CM (the up connection of UL-) ".This operational mode that only is used in the up connection of compact model is favourable in terminal when subscriber board is equipped with second receiving system in other words for example, yet this subscriber board but must for example be measured in the GSM1800 frequency band near the UMTS frequency band, keeps being connected of existing and first receiving device on described UMTS frequency band.Under such a case, the GSM that the continuous transmission of the subscriber board on the UMTS channel (UE UMTS DCH transmission) that distributes can be subjected to carrying out with second receiving system measures strong the interference.

Second operational mode is used for the operational mode of up connection and the descending compression that is connected, and is called as UL/DL CM (DL:Downlink down link).This operational mode is used for avoiding requiring subscriber board second receiving system and also avoiding requiring second synthesizer.If adopt the single receiving platform that has two synthesizers, for example to carry out measurements (GSM900 Inter RAT measurements) among the RAT in the GSM900 frequency band, then can adopt at only with the 3rd operational mode of the descending connection (being called " the only DL in CM ") of compression operational mode.

Fig. 2 illustrates the principle of the operational mode of compression.By a plurality of frame fr (frame) transmission data, wherein, this moment one with maximum between seven time slots of every frame fr can occupy to carry out described measurement by described subscriber board.These time slots or be in the middle of the single frame fr or be distributed on two frame fr.In the frame frc of described compression, improve transmitting power P and keep quality of connection constant thus.Thereby the frame of such compression is made up of the data cd and the space G of compression.Can especially on other frequency, measure on other resource at described subscriber board during the G of space.Compress which frame fr, frc by network or communication system decision.The frame frc of compression can determine also can ask to determine periodically.The speed of the frame frc of compression and type are variable and for example depend on the kind of the measurement of being undertaken by subscriber board.The structure of the operational mode of compression is assigned to definite subscriber board, and wherein said structure is different between the different a plurality of subscriber boards in the sub-district usually.Thereby by the transmission frame number certificate, the part of wherein this frame frc as condensed frame frc has transmission space G, does not send data in described transmission space G in the operational mode of compression.

In addition, for such communication system is provided with multi-media radio electricity broadcast transmitted and so-called multicast service (MBMS:Multimedia Broadcast and Multicast Service, multimedia broadcasting and multicast service), it is such business, in base station described in the described business in the common general information of interest of using of channel.The channel of this common use is listened to by a plurality of subscriber boards.Described general signal for example can be similar to the videotext in the TV or pass through the content of DAB (digital audio broadcasting) transmission, yet also comprises the business such as multimedia.For example can be via single channel by of the goal of a kind of like this business to many subscriber board transmission football matches.Yet do not have a continuous transmission of transmitting the space via but being that plan is a kind of under the situation of such Channel Transmission.In the time in the reception space aspect receiving platform, corresponding transmission space is not set but aspect the transmitting station under the MBMS situation, thereby during receiving the space, loss of data occurs.

Therefore, along with being that UMTS introduces MBMS, the physical channel (S-CCPCH) that MBMS occurs being used for is not supported the problem of the operational mode (CM) compressed.Under subscriber board is in situation in the connection that is distributed, be apparent that, in a moment that described subscriber board is measured, can be lost in the data that this time transmits in the S-CCPCH of correspondence frame under the situation of the operational mode of compression.This causes losing the MBMS data with continuous sequence transmission by channel S-CCPH.At this, the data volume of losing depends in the frequency in length, space in space and the subscriber board the effectively quantity of CM sequence.

Fig. 3 illustrates the example of data structure, how to receive described data structure via the connection that so-called DPCH channel in the operational mode of compression (DPCH:Dedicated Connectionin CM, the special use among the CM connects) passes through to be distributed shown in the diagram up by subscriber board.Below shown in the diagram, by receiving under the continuous data conditions when receiving MBMS reception or do not receiving which data by a kind of like this radio broadcasting channel S-CCPCH to have the operational mode that receives the space as the subscriber board of receiver.Subscriber board carries out various measurements, for example the signal strength signal intensity of measure GSM signal (GSM RSSI:Received Signal StrengthIndicator, the S meter of reception).Other measurement is for example carried out and is carried out aspect the FDD alien frequencies at base station identity code BSIC.Obviously, if subscriber board has only single receiving system and therefore must change receive frequency, in the data that can lose during this Measuring Time on the channel S-CCPCH.

If subscriber board is in a kind of forward access channel status (CellFACH (Forward Access Channel) state) of sub-district, similar problem can appear, in the forward access channel status of described sub-district, distribute up direction transmission channel generally predetermined or that separately use, the direct access channel RACH (Random Access Channel Random Access Channel) that for example described subscriber board can use for access procedure at any time to described subscriber board.Access to the FACH of described sub-district is characterised in that the position of subscriber board is known at described subscriber board for the terrestrial radio access network (UTRAN:UMTS Terrestrial Radio AccessNetwork) of UMTS on the cell level aspect the sub-district of wherein carrying out cell updating course at last.Under this state, do not distribute the channel of fixed allocation, and do not require measurement according to the operational mode of compression to described subscriber board.Yet described subscriber board must constantly be monitored FACH and be carried out different-frequency measure periodically and different RAT measurement on down direction.The duration of measuring process is corresponding to being maximum transmission time duration of (TTI:Transmission TimeInterval) at interval on the channel S-CCPCH that adopts of messages broadcast by radio or MBMS, this can be by described subscriber board observation, wherein every 2 ^kThe TTI Transmission Time Interval according to current regulation of individual 80ms carries out described measurement process, at this k=1,2,3.Measuring under the situation of duration as maximum length in time with the TTI of 80ms, looking the selection of k value and the measuring period of the different 160ms of having, 320ms or 640ms.For clarity, the example of the subscriber board when Fig. 4 illustrates k=2 in the FACH state of so-called sub-district.Under the situation that requires different-frequency measure and RAT to measure, the MBMS that interrupts once on the channel S-CCPCH in correspondence every the described subscriber board of 320ms receives.

Shortcoming in all these methods is, under the situation of the operational mode of compression, subscriber board is merely able to be received in by halves on the channel S-CCPCH continuously and the data that send constantly.Currently studying various schemes of dealing with problems.A scheme is, knows that the transmitter in the space aspect the subscriber board that receives interrupts the transmission of MBMS and the transmission (DTX:Discont inuous Transmisson) that is interrupted at this time durations simply.

Another kind of scheme is, data in the described subscriber board try reconstruct disappearance of recipient, for example by the decoding under the situation that adopts forward error correction (FEC:Forward Error Corretion), for example by means of known Tutbo coding/decoding method and nested (Interleaving is staggered) method.Yet these schemes but are problematic, because be in the sub-district and the measurement space at recipient's different user platform that receive the MBMS data is not aligned with each other in time.The counter structure in described space that is to say specific to measuring, and depends on the mode of the measurement of being undertaken by subscriber board, that is to say, for example depends on that different-frequency measure or different RAT measure, and wherein this for example also depends on the position of described subscriber board in the sub-district.

At present preferred scheme is that different-frequency measure or different RAT measure by described subscriber board and adopt the reception (DRX:Discontinuous Reception) that is interrupted to implement at the MBMS reception period.Do not have interruptedly transmission and MBMS transmission data in the case, the wherein single subscriber board that receives is lost in the MBMS data that do not have reception when implementing different-frequency measure and different RAT measurement simply.By adopting forward error correction, the data of the necessary try reconstruct disappearance of described subscriber board.

Task of the present invention is, be provided for when receiving, having the method a kind of alternative and that preferably improve of the sequence that receives the data that sent under the situation that receives the space, a kind of communication system that is used to send the corresponding suitable method of data sequence, a kind of receiver and a kind of correspondence perhaps is provided.

The receiver of the method that be used to receive the data that with sequence send of this task by a kind of feature according to claim 1, the method that is used to send data sequence by a kind of feature according to claim 2, the mobile communication system by a kind of feature according to claim 14 and finish according to the mobile radio system device of the feature of claim 15.

In view of the above, preferred a kind of method that is used for receiving the data that first transmitter of mobile radio system sends with sequence on first element of resource of resource by receiver, the space wherein appears receiving when receiving, and, the data that do not receive during receiving the space are rebuild by receiver, wherein the data that do not receive from first transmitter are offset or the ground (verwuerfelt) that is shifted is being received between described reception space on the same asset key element of described resource from second transmitter in time, and are used to from data to rebuild described sequence.

In view of the above, scheme or combination as an alternative, preferred a kind of method that is used for sending at least one receiver from transmitter by the element of resource of resource data sequence at mobile radio system, wherein said mobile radio system has second transmitter that has the emitting area that overlaps with the emitting area of first transmitter, wherein send with being offset ground or displacement in time, make and to rebuild owing to the reception space on the described element of resource in the data that when first transmitter receives data, do not receive the recipient to carrying out the data of second transmitter on same element of resource with a deviation by the data transmission of first transmitter.

In view of the above, preferred a kind of receiver that is used for mobile radio system, it has the receiving system that is used for the data sequence that receiver/transmitter sends on the element of resource of resource, wherein said receiving system interrupts reception on described element of resource in short time to change described element of resource in short time, occur to receive the space thus, wherein the data that do not receive during receiving the space are received and processed to rebuild this data sequence from second transmitter with being offset in time.

In view of the above, the mobile radio system device of preferred a kind of mobile radio system, it has at least two transmitters that have the emitting area that overlaps at least in part, described transmitter sends data sequence, wherein said transmitter is designed to adopt respectively the identical element of resource of resource to send described data, one of them the transmission of wherein said transmitter is designed to, and the skew ground of comparing to corresponding data element or data block skew ground or with another transmitter sends individual data unit or data block.

The favourable theme that expands to dependent claims of the present invention.

Especially preferred a kind of method wherein adopts as described element of resource and transmits and receives frequency, especially adopts the frequency of FDD mobile radio system or FDMA mobile radio system.

Especially preferred a kind of method, wherein the recipient owing to described reception space appears in another element of resource that described element of resource is transformed into described resource in short time.

A scheme like this can also forward the situation of other loss of data to, for example when since disturb can not receiving data sequence individual data the time, for example at second receiving system with effectively measure under the situation in the adjacent frequency band that is having higher interference effect.Under the situation of the external disturbance that causes owing to external interference source, also can divert from one use to another described method.

Especially preferred a kind of method, wherein said mobile radio system is to have a kind of communication system that is used for sending the element of resource of data sequence on the duration, and described at least one receiver is being ended reception in short time in order to receive on another element of resource on this duration, and cause described reception space thus.

Especially preferred a kind of method, wherein, the data sequence of the described data sequence (especially data block) when sending by second transmitter when sending by first transmitter correspondingly having in the data block of element of limited quantity and exchanged.A kind of like this exchange, just a kind of displacement can be carried out or carry out randomly on intercycle ground, subregion.

If described transmitter is synchronous, for example in the sector of a sub-district, so the partial data that periodical exchange is as far as possible little simply zone just can prevent not free by the identical data of a plurality of transmitter transmission, the needed memory of the data that reorder in this external receiving system is very little.In addition as long as exist the packet that has the packet numbering that identifies described order just can simply rearrange.If just the order that remains unchanged with individual data unit carries out temporal passing, so also can have the data sequence of reception of data element of disappearance and the crosscorrelation (Kreuzkorrelation) between the data sequence that another transmitter is sent, under the situation of finding out corresponding data element, to compare.

Preferably, will notify described travelling carriage by passing or displacement that adjacent stations adopts.This both can be undertaken by the signaling of dominance, also can be by another sign amount, for example transmit cell ID ID and transmit recessively.For example can be from being to calculate the passing of being adopted the sub-district ID of mould with maximum passing value, in other words can be from the displacement quantity used quantity as the displacement of calculating displacement usefulness the sub-district ID of mould.

If yet described transmitter is asynchronous, preferably do not carry out pure periodical exchange, because can not prevent from not occur when random time is passed arbitrarily between two transmitters following situation like this, promptly two transmitters are in the identical identical data of time transmission.Can carry out the subregional special displacement at random of as far as possible little data portion at this, thereby be that the required memory of rearrangement in described receiving system is still very little.

Especially preferably a kind of like this method, wherein the data element of data or data block when sending by second transmitter with respect to the skew that sends this data element or data block by first transmitter corresponding to the time span in the described reception gap of twice at least.

Especially preferably a kind of like this method, a kind of like this receiver or a kind of like this mobile radio system device, it is used for implementing a kind of method of reseptance according to UMTS compact model method receiving under the data conditions of considering the emission of compact model ground continuously and not.

Especially preferably a kind of like this method, a kind of like this receiver or a kind of like this mobile radio system device, wherein first and second transmitters are transmitters of two sectors of single transmitting station.

Especially preferably a kind of like this method, a kind of like this receiver or a kind of like this mobile radio system device, described skew this moment makes it possible to instant reconstruction, especially is no more than the duration of a frame.

The sector of a described skew or a for example relative sub-district is zero, or fully arbitrarily.Described periodic exchange does not relate to all data streams, but only relates to partial data stream, especially as far as possible little part.

Explain embodiment by means of accompanying drawing below.

Fig. 1 schematically illustrates the station of the mutual communication of mobile radio system;

Fig. 2 illustrates the data structure according to the compression operational mode of prior art;

Fig. 3 is illustrated in the reception structure and the application of described compression operational mode on the data of the continuous emission that continues of receiver under the situation about measuring in the compression operational mode.

Fig. 4 illustrates a kind of honeycomb and moves reception data diagram under the situation that FACH receives operational mode.

Preferably carry out selectivity combined reception (SC:SelectiveCombining) by subscriber board UE.For this reason, in adjacent sector and/or sub-district, send identical data content to subscriber board, that is to say identical data or packet from base station more than one.Do not add any restriction at this synchronization aspects in data itself.In known methods, for example subscriber board carries out different-frequency measure or different RAT measurement in according to the compression operational mode of UMTS, and can not be received in all data on the MBMS channel.Yet, be reconstituted in to measure and receive the data that send during the space but do not receive during the space in other words.Except the possibility of known forward error correction (FEC), this carries out in the following manner, and promptly the time with skew or displacement mutually sends the packet in other words of described data in adjacent and sector that overlap mutually and/or sub-district.Described thus subscriber board receive the data that do not receive during the space can by same resource the time point that staggers from adjacent sub-district or adjacent sector be received, and be used to rebuild.

Fig. 1 schematically illustrates a kind of layout of the different device of mobile radio system (for example according to UMTS mobile radio system), and the data of wherein transmitting between the station.Yet what have the problem compared in principle is possible in transmission on other mobile radio system and the transmission on other operational mode in case of necessity.Especially except employing has two base station B1, B2 that separate of accordingly sub-district c1 own or c2, can also adopt the single base station that has fan antenna device and sector cell.

What specifically illustrate for example is three base stations as transmitter B1, B2, B3.These three base stations be connected with the control device CC at center and aspect sending data and establishing a communications link in heart controlled.The control device at this center can be so-called RNC (RadioNetwork Controller, a radio network controller) in UMTS.

Subscriber board plays receiver UE and is in the overlapping region of sub-district c1, c2 of the first or second transmitter B1, B2.Between receiver UE and the first transmitter B1, there be special-purpose being connected.Receiver UE is in a kind of operational mode, and the first frequency of the first element of resource f1 that the land productivity of occupying an leading position in described operational mode is used as the resource frequency of FDD method receives data from the first transmitter B1.Receiver UE switches to the second element of resource f2 in short time on interlude, switches to second frequency in other words, to measure in this frequency.Can not receive the data b of the sequence of the data a, the b that send by the first transmitter B1 by first frequency f1, c, d, e at this time durations.Data sequence a-e is should be by the described first transmitter B1 by utilizing radio broadcasting channel as the first frequency of the first element of resource f1 to a plurality of data element or data blocks in user side's receiver UE transmission.Therefore, described receiver UE for example from the first transmitter B1 receive the MBMS data, by the subscriber board of the operational mode work of the compression of UMTS.

Described in addition receiver UE also is in the effective radius of the described second transmitter B2.The receiver UE of the described second transmitter B2 in the scope of its sub-district c2 sends the same data of data sequence a-e.For can compensated receiver UE because its reception space during by operational mode operation of compression, the second transmitter B2 to the correspondence by the first transmitter B1 send skew ground in time, for example displacement ground sends these data of data sequence a-e with same element of resource f1 (just using same first frequency) preferably.Exist the very high described receiver UE of probability to receive the data b of losing thus based on the temporal displacement of the second transmitter B2.

Described displacement method is in every way worked.Except the individual data unit or data block of passing ground transmission data sequence a-e at different time points by described two transmitter B1, B2 on the time, can also when individual data unit that sends data sequence a-e or data block, carry out the exchange of described order.A kind of like this exchange can be carried out or carry out randomly periodically.

When sending the skew of data, the skew of selecting to be undertaken by the second transmitter B2 preferably considers the duration in described reception space.Described skew is selected greater than a duration that receives the space accordingly.Especially preferably be at least the skew that receives the space twice.

In another expansion, described skew is selected at least so greatly, make this skew corresponding to current passage of time between described reception space and two the adjacent transmitters or maximum time passing with.The space can not damage not is the reception of the packet of sending from these two transmitters so guarantee to receive.

Advantageously, so a kind of scheme is also considered the problem of the transmitting power loss aspect transmitter B1, the B2 when sending the data of data sequence a-e by the MBMS channel, to reduce desired power.Also make it and to reach by the data of optionally choosing different transmitters in receiver side.Under the situation of MBMS, coordinate the transmission of the data a-e of different adjacent and sector that overlap mutually or sub-district c1, c2 in terms of content by the network of for example center control device CC.Yet compare for mrc (Maximum Ratio Combining) in the zone of the synchronous requirement of the selectivity that will implement like this combination and at least some TTI and not to be strict.

Under the situation of the inner synchronous in other words emission of harmonizing in the sector of for example sub-district, advantageously improve reconstruction capability in receiver UE side but exchange the data that will send by mode with a kind of paired displacement.For example under a kind of like this situation of paired displacement, send sequence { a, b, c, d, e, f}, and sequence { b, a, d, c, f, e} that second transmitter B2 transmission is replaced in couples by first transmitter.This advantage that provides is, rearranges to only require that in receiver side very small amount of data buffer zone, described receiver normally receive the data of the second transmitter B2 and must rearrange the data of all receptions.Send under the situation with frame that these data that these data are but replaced are in couples arranged yet send at the same time under the situation of the frame have many such data elements in other words by another transmitter, this paired displacement just provides during the different-frequency measure or prevent the high reliability of data element or dropout of data block during different RAT measures on identical S-CCPCH MBMS TTI.

If transmitter B1, B2 do not harmonize on transmitting time point in time, the random permutation of data element is favourable.If under the data conditions that send skew like this by two transmitter B1, B2, receive described optionally combination, in any case this guarantee to have transmitter B1, B2 with length be that the data of 1 MBMS S-CCPCH TTI are rebuild.For example can adopt such displacement, wherein send the sequence replaced by the second transmitter B2.Described displacement is carried out under the situation of the sequence that adopts the first transmitter B1, and wherein corresponding four or more data unit or data block are replaced mutually.Data element 1 passes to the position 3, data element 2 passes to the position 4, data element 3 passes to the position 1 and data element 4 passes to the position 2.In order to upset cyclophysis, additionally have four or these data elements of displacement between the group of multidata unit more illustrated.

The delay of the displacement of data element or displacement or described individual transmitter can be undertaken by described individual transmitter (perhaps attaching troops to a unit to its parts).Yet this also can be undertaken by heart in the transmitter of this control device control for all by the control device CC (for example RNC) at center.The latter's advantage is, this function need only be implemented in fewer network devices, especially also need only be maintained displacement and replace in other words or postpone needed memory in this device.

In another kind of embodiment, can also stipulate one group of sequence order (displacement).All obtain a sequence order in each base station of each time point, wherein change described sequence order regularly from this group.Select described sequence order in an advantageous manner randomly, perhaps pseudorandom ground is selected, and that is to say under the situation that adopts the pseudo-random algorithm of selecting according to known parameter decision to select, and described known parameter for example is sub-district ID and current frame number.By adjacent cell selecting sequence order at random, guarantee irrespectively to guarantee to utilize the minimum probability of rebuilding from the transmission of the packet of these two sub-districts with the temporal skew that sends.At this, described probability depends on the quantity (at least under the situation of suitably selecting described sequence order, as hereinafter illustrated) of described sequence order.When 4 sequence order for example, the probability (because only selecting to cause sending simultaneously the sequence order of related packet in 1/4th situation) of 75% minimum is arranged.Therefore, the statistics that this method leads to a conflict is average, and prevents that especially described conflict from for good and all appearing on definite position.

The advantage of this embodiment is a synchronized cells in time not, and needn't implement to be used to distribute the liaison plan of described sequence order.

Be typically, synchronously each sub-district, the sector of for example launching in network from common position, on the contrary, asynchronous other the sub-district, for example in other locational sector.Also can advantageously use described method in this case: adopt common (puppet) randomizer for synchronous sub-district, then on the value that described randomizer sends in addition specific to the bias of sub-district, the codomain of wherein said randomizer is identical with the quantity of sequence order, and adds that the quantity by described sequence order is the bias of mould.At this, must distribute described bias, make adjacent sub-district obtain different biases.Yet because the quantity of synchronous sub-district is typically very little, especially much smaller than the sub-district sum of network in described sight, so this distribution is easy to and can local ground plan.Need especially not need the plan of network range about the plan of nonsynchronous sub-district.Thereby guarantee that adjacent synchronous sub-district always adopts different sequence order, and statistics average effect as explained above under the situation of adjacent nonsynchronous sub-district, occurs simultaneously.

The sector in other words more than sub-district c1, the c2 of two transmitter B1, B2 is usually arranged in the system of reality.In order to guarantee that sub-district adjacent under such a case has different displacements to replace in other words, adopts at least four sequence order.According to known four chromogens reason, each map can be with four color dyes, make adjacent area all with different colors, this means also and can distribute sequence order like this, make the different sequence order of the total employing in adjacent sub-district.Thereby subscriber board of guaranteeing each two so adjacent sub-district of reception can both be rebuild the data of disappearance.

The group that 4 sequence order of 4 elements are arranged for example is following group (sequence order group 1):

{a、b、c、d}，

{d、a、b、c}，

{c、d、a、b}，

{b、c、d、a}

As can be seen, each appearance of the every row of element a to d and every row once.This is essential, therefore, thereby yet receive two sub-districts and but can surely receive this packet once more at the UE that a time point can not receive two sub-districts because each packet must just be sent once (OK) and is sent out from proper what a sub-district in each packet constantly by each sub-district.If thereby the minimum spacing between the packet by different sub-districts sends must can protected reception greatly, just whenever to list the criterion that shows once be inadequate to each element so.Therefore very clear, the sequence order group of length 4 can comprise maximum 4 sequence order (saying that at large the sequence order group of length n can comprise maximum n/m sequence order, wherein must be greater than m by the spacing between the packet transmission of different districts).

The characteristic of this special sequence order group is the periodic mutually exchange of described sequence order.As preamble explanatorily, can produce the sequence order group of random length by the exchange in cycle in simple mode.The maximum quantity of the sequence order that each group is possible depends on the length and the minimum spacing between the transmission of packet on the different sub-districts of sequence order.So always can find suitable group by these parameters of suitable selection.

Another group with 4 sequence order of 4 elements is following group (sequence order 2):

{a、b、c、d}，

{b、a、d、c}，

{c、d、a、b}，

{d、c、b、a}

The feature of this group is, second sequence is the paired displacement of first sequence, and the 4th sequence is the paired displacement of the 3rd sequence.As the front explanatorily the advantage of sequence of paired replacement be a data buffer zone that only needs seldom.Yet can not be formed in wherein all sequences and all be differently the sequence of displacement in pairs, more than the group of two sequences.With regard to sequence order 2, as long as it comprises at least two pairs of sequence the bests of displacement in pairs.

Described group can also illustrate by following formation rule:

Two sequences of replacing in pairs from length 2:

{a、b}，

{b、a}

Continue this sequence similarly, occur two of length 4 sequences of displacement (adopt other letter for described continuation, that is to say with c to replace a and replace b) in pairs thus to obtain unique mark with d:

{a、b、c、d}，

{b、a、d、c}

Add further sequence, wherein by exchange first semi-order row and second semi-order row (at this from { a, b, c, d} generation sequence { c, d, a, b}, because exchanged semi-order row " a, b " and " c, d ") constitute the sequence of described interpolation from existing sequence, this draws sequence order group 2):

{a、b、c、d}，

{b、a、d、c}，

{c、d、a、b}，

{d、c、b、a}，

Can produce the group that its length is the sequence order of two power with this formation rule, for example next length is 8 group:

{a、b、c、d、e、f、g、h}，

{b、a、d、c、f、e、h、g}，

{c、d、a、b、g、h、e、f}，

{d、c、b、a、h、g、f、e}，

{e、f、g、h、a、b、c、d}，

{f、e、h、g、b、a、d、c}，

{g、h、e、f、c、d、a、b}，

{h、g、f、e、d、c、b、a}

Comprise two the in pairs groups of the group of the sequences (and being best equally) of displacement with 4 sequence order of 4 elements below being (yet this group but has " inferior " slightly, because be not so symmetrical) (sequence order group 3) equally on aforementioned meaning:

{a、b、c、d}，

{b、a、d、c}，

{d、c、a、b}，

{c、d、b、a}

If renaming and going to exchange of element foreclosed, just have only four groups of 4 sequences altogether with 4 elements, what also do not enumerate is (sequence order group 4):

{a、b、c、d}，

{c、a、d、b}，

{b、d、a、c}，

{d、c、b、a}

All these four groups can be preferably used in the mobile radio system, sequence order 2 is as the sequence that exchanges in pairs and especially outstanding owing to the formation rule of symmetry, yet sequence order 3 (not considering performance is had only the formation rule of less important meaning) but has equal value.
