Embodiment

Disclose a kind of be used for providing support carry out in communication system that signal sends and equipment, method and the software of the mechanism of addressing.In the following description, for illustrative purposes, various details have been carried out setting forth so that the complete understanding to embodiment of the present invention to be provided.Yet, it is apparent that do not have these details or also can put into practice the present invention for those skilled in the art by the setting that is equal to.In other examples, show known structure and equipment with the block diagram form, thereby avoid embodiment of the present invention is produced unnecessary bluring.

Although at spread spectrum system and at random or PN (pseudo noise) sequence embodiment of the present invention is discussed, but what those skilled in the art will recognize that is that the present invention can be applicable to communication system (including spider lines) and other sequences of any kind.

Fig. 1 is can supporting signal the sending and the structure chart of the wireless system of addressing of various execution modes according to the present invention.Wireless network 100 comprises one or more accessing terminal (AT) 101, and one of them AT101 is depicted as by air interface 103 and access network (AN) 105 and communicates.According to an execution mode, this system 100 provides third generation partner program 2 (3GPP2) cdma2000 High Rate Packet Data revision B (being also known as multicarrier HRPD, multi-carrier DO, DO Rev.B, and NxDO) network.In another embodiment, the present invention can be applicable to the system based on OFDM (OFDM), for example cdma2000 High Rate Packet Data revision C (being also known as the cdma2000 evolution stage 2, DO Rev.C).For example in DO Rev.B and the DO Rev.C system, AT 101 is equal to travelling carriage at cdma2000, and access network 105 is equal to the base station.AT 101 is the equipment that provides data to connect to the user.For example, AT 101 can be connected to computing system, personal computer for example, personal digital assistant or the like or support the cellular handset of data, services.In DO Rev.B system, radio configuration comprises two operator scheme: 1X and multicarrier (being nX).Multicarrier system adopts a plurality of 1X carrier waves to improve the data rate that leads to AT101 (or travelling carriage) by forward link.Therefore, different with the 1X technology is that multicarrier system is operated on a plurality of carrier waves.In other words, AT 101 can visit a plurality of carrier waves simultaneously.

In one embodiment, medium access control (MAC) address (or index) is used to indicate the origin or the destination of the information of being transmitted, because a plurality of communication nodes are always arranged in system 100.In this example, MAC index (MAC ID) is assigned to the terminal 101 in the wireless system 100.Start or destination when being the grouping of AT 101 or message when having, transmit source or the destination of specific MAC Address with identification packet or message from AT 101.

Particularly, when transmitting by forward traffic channel, AN 105 MAC index on probation identify target AT (for example AT 101) .For example, each Walsh channel identifies by the MAC index value, the 3GPP2C.S0024-A exercise question of and has defined Walsh covering and unique phase modulation. in March, 2004 is in " cdma2000High Ratepacket Data Air Interface Specification ", at the A.S0007-A v2.0 in May, 2003 exercise question for providing the more detailed description to HRPD in for " InteroperabilitySpecification (IOS) for High Rate Packet Data (HRPD) Access NetworkInterfaces " in " Interoperability Specification (IOS) for HighRate Packet Data (HRPD) Access Network Interfaces-Rev.A " and at the 3GPP2A.S0008-0v3.0 exercise question in May, 2003, its this by with reference to and integral body is incorporated this paper into.

AN 105 is the network equipments that for example provide data to be connected between Global Internet 113 and the AT101 at packet switched data network.AN 105 communicates via Packet Control Function (PCF) 109 and packet data serving node (PDSN) 111.AN 105 or PCF 109 provide SC/MM (session control and mobile management) function, it also comprises storage HRPD session related information except other functions, carry out terminal authentication procedure determining whether should authenticate just at access of radio network the time to AT 101 as AT101, and the position of managing AT 101.PCF 109 is to be described in " 3GPP Access Network Interface InteroperabilitySpecification " at the 3GPP2A.S0001-Av2.0 in June calendar year 2001 exercise question further, and integral body is incorporated this paper into by reference at this for it.

In addition, AN 105 and AN-AAA (authentication entity) 107 communicate, and it provides terminal authentication and authorization function for AN 105.

Cdma2000 1xEV-DV (evolution-data and voice) and 1xEV-DO (data of evolution-optimization) air-interface standard have been formulated Packet Data Channel to be used for by air interface in forward link and the grouping of reverse link transmitting data.Various types of services that provide are provided wireless communication system 100.These services can comprise ptp services or service-specific for example voice and grouped data, and data are transferred to specific receiving terminal from transmission sources (for example base station) thus.This service can also comprise point-to-multipoint (being multicast) service or broadcast service, and data are from sources transmit to a plurality of receiving terminals (for example AT101) thus.

In multi-address radio communication system 100, communication between the user is undertaken by one or more AT 101, and the user's (accessing terminal) on wireless station is by passing to the base station with information signal on the reverse link and communicating with second user on second wireless station.AN 105 receives this information signal, and on the forward link information signal is passed to the station 101.This forward link is meant from AN 105 to wireless station 101 transmission, and reverse link is meant from the transmission of the station 101 to AN 105.AN 105 receives data first user from the wireless station on the reverse link, and routes data to second user on the main line station by PSTN (PSTN).In a lot of communication systems, for example in IS-95, among wideband CDMA (WCDMA) and the IS-2000, be forward link and the independent separately frequency of reverse link assignment.

In the exemplary embodiment, AN 105 comprises that High Rate Packet Data (HRPD) base station is to support the service of high data rate.Should be understood that, the base station via one or more transceivers access terminal and network between radio frequency (RF) interface (one or more carrier wave) is provided.The HRPD base station provides independent clear data (DO) carrier wave, is used for the HRPD application at each sector (or sub-district) of HRPD base station services.Independent base station or carrier wave (not shown) provide one or more voice carriers for voice application.It can be that DO accesses terminal or bimode mobile terminal that HRPD accesses terminal, its can use voice service and data, services the two.In order to participate in data session, HRPD accesses terminal and is connected to the DO carrier wave to use the DO high-speed data service.Data session is controlled by packet data serving node (PDSN) 111, its HRPD access terminal and the Internet between all packets of route.PDSN 111 has towards the direct connection of Packet Control Function (PCF) 109, and it is connected with base station controller (BSC) interface of HRPD base station.BSC is responsible for the processing of operation, maintenance and supervision, speech coding, rate adapted and the Radio Resource of HRPD base station.Should be understood that, BSC can be independent node or can with one or more HRPD base station co.

In the 1x carrier wave, each HRPD base station can be served a plurality of (for example three) sector (or sub-districts).Yet, should be understood that each HRPD base station only can be served single subdistrict (being called omnidirectional (omni) sub-district) usually.Should be understood that network 100 can comprise a plurality of HRPD base station, each base station services is in one or more sectors, and wherein the HRPD portable terminal can switch between the same HRPD sector of base station or between different HRPD sector of base station.For each sector (or sub-district), single shared time division multiple access (TDM) forward link is further adopted in the HRPD base station, one of them single HRPD portable terminal can be divided into groups to serve by unique user, and a plurality of portable terminal can be divided into groups to serve at any example place by the multi-user.Forward link throughput rate is shared by all HRPD portable terminals.HRPD accesses terminal by its data rate control (DRC) being pointed to this sector and being asked forward data rate to select the serving sector of HRPD base station (sub-district) according to channel condition carrier wave-interference (C/I) ratio of channel (promptly based on).

Wireless communication technology continues evolution and thinks that the multiple application with different characteristic provides higher data rate and better service quality.Cdma2000 High Rate Packet Data (HRPD) standard provides high data rate by the 1.25MHz carrier frequency.This system is provided at clear data (DO) service on the 1.25MHz carrier wave (1x), and it is called 1x DO system sometimes.Provide in order further to improve service, this cdma2000 HRPD standard need be considered multi-carrier CDMA system.In this system (refer in multicarrier HRPD (MC-HRPD) system, or Nx DO system), access terminal (AT) can transmit and/or receiving data stream on a plurality of 1.25MHz frequency bands.

A method holding a plurality of AT in multi-carrier operation is in the 3GPP2 on June 20th, 2005 contribution, C25-20050620-030, exercise question is for making an explanation in " Increased Forward LinkMAC Indices for Multi-Carrier Operation " (it incorporates this paper at this into by reference integral body).

In the 1xDO system, each AT 101 is assigned medium access control index (MACID).Identify the grouping that is transferred to each AT 101 by this MAC ID; This addressing is necessary, thereby AT 101 (it is known wherein having only) will be not can not obscure other users' grouping and is its oneself grouping, and vice versa.What traditional method was indicated is that each 1xDO carrier wave has 64 MAC ID to use at most in DO Rev.0, and each 1xDO carrier wave has 128 MAC ID to use at most in DORev.A.Along with the increase of capacity in the NxDO system, the DO of being carrier wave likely need be supported the AT more than 128, and this causes MAC ID shortage.As mentioned above, traditional addressing scheme autgmentability is bad.

Fig. 2 is the flow chart of the mechanism that is used for addressing of various execution modes according to the present invention.According to one embodiment of the present invention, this addressing mechanism use has good being correlated with, and (sequence of for example hanging down association attributes is indicated the communication information (for example MAC Address), shown in step 201.An embodiment of the invention are used long PN (pseudo noise) sequence.

In step 203, each MAC Address is mapped to sequence (for example PN skew).In this way, can utilize the PN sequence of given length to indicate a large amount of MAC Address.When keeping low spending, can be from eliminating the MAC Address problem of shortage in essence.

For example, can consider following PN sequence generator polynomial (generator polynomial):

p(x)＝x ¹⁵+x ¹³+x ⁹+x ⁸+x ⁷+x ⁵+1.

This has generated length is 2 ¹⁵The PN sequence of-1=32767.In order to obtain zero offset PN sequence, and for the simplified system design with realize, can insertion ' 0 ' in sequence after 14 ' 0 ' continuous output.Sequence table is shown b ₀b ₁... b ₃₂₇₆₇MAC Address can be mapped to a part of sequence.

Purpose for signal has defined 15 bit mac addresses.With each 15 bit mac map addresses to 256 PN sequence.For example, MAC Address 37 is mapped to sequence b ₃₇b ₃₈... b ₂₉₂And MAC Address 2005 is mapped to sequence b ₂₀₀₅b ₂₀₀₆... b ₂₂₆₀Further, MAC Address 32767 is mapped to sequence b ₃₂₇₆₇b ₀b ₁... b ₂₅₄Or the like.In this way, can utilize 256 MAC Address to support 32768 MAC Address.It should be noted that if the requirement of all MAC Address sequences is a quadrature, then utilize 256 bit mac addresses at most only to support 256 MAC Address.Compare with the method for using quadrature MAC ID sequence, under the method, can support 128 times of MAC ID to it.

In step 205, based on sequence of mapping, promptly communication information sequence is handled the signal of the expression communication information.Next, in step 207, transmit this signal by communication system 100.In step 209, from this signal, extract the communication information based on communication information sequence.

Can recognize that for specific mapping, relevant between two deviation posts can be very big.Therefore, can adopt further randomization to change skew in the PN sequence.For example, can use the transmission time to change the position of the skew of PN sequence.Can use hash function to determine this skew based on MAC ID and time index.In the exemplary embodiment, this function is as follows:

Skew=(MAC ID*n+ time index * m) mod (PN length),

Wherein PN length=32768 are the length of PN sequence.

Can be in another illustrative embodiments shown in the context of multicarrier cdma2000HRPD system.In the case, can utilize 64 many bi-orthogonal sequences to support maximum 128 MAC index on the 1x HRPD system conventional.In order to support the MAC index more than 128, in one embodiment, signal transmitter system is used the pseudo random sequence according to above-mentioned PN sequence generator polynomial.

According to an embodiment of the invention, imagination AN 105 is assign bi-orthogonal MAC ID sequence (preamble sequence) at first still.It should be noted that AN 105 only can support to be less than 128 MAC ID by this method.When AN 105 utilizes greater than 128 MAC_ID when AT 101 sends sole users' grouping, AN 105 uses a part of PN sequence to be used for the AT 101 of this time slot as MAC ID sequence (preamble sequence).The skew of MAC ID sequence can followingly be calculated:

Skew (MAC_ID, time slot index)=(MAC_ID*64+ time slot index) mod32768.

For example, if AN 105 utilizes MAC_ID=156 to come to the new sole user's grouping of AT101 transmission at time slot 25, then the skew of preamble sequence is (156*64+25) mod32768=10009.The length of preamble sequence depends on transformat.For example, transmit if having the grouping of transformat (2048,2,128), then preamble length is 128.In the case, preamble sequence is b ₁₀₀₀₉b ₁₀₀₁₀... b ₁₀₁₃₆Therefore, the quadrature MAC ID sequence that AT distributed can not be subjected to special influence, because this preamble sequence b ₁₀₀₀₉b ₁₀₀₁₀... b ₁₀₁₃₆Be similar to random data.Therefore, this time slot can be by the every other AT except target AT as there not being the time slot of lead code to treat.In specific implementations, the length of MAC ID sequence is variable, for example as the function of time, MAC ID, transformat etc.And length can change between different users and different time.

Can be contemplated that and to implement described signal transmitter system with multiple form.For example, any sequence except random sequence or pseudo random sequence can be used for signal transmitter system.And the mapping between MAC ID and the skew needs not be man-to-man.That is to say, mapping can be one to one, one-to-many, many-one and multi-to-multi, or the various combinations of these mappings.

In addition, the mapping between MAC ID and the skew can change according to the time, or changed via the exchange of agreement/pattern (pattern) that limits or signal transmission message.Skew can be for example MAC ID, time, communication session and be connected the function of configuration, communication service type and service quality (QoS) parameter.

Although be described at addressing, signaling method also can be used for indicating as substituting or additional other information (for example communication information) MAC ID.For example, transport format information is data rate, encoder packet size, automatic repeat requests (ARQ) channel id, Sub-Packet ID for example, and perhaps the combination in any of these information and this information are in conjunction with the combination in any of MACID.

Further, it is relevant to reduce to carry out processing to the sequence of mapping.For example, signal transmitter system can be cancelled one or more MAC ID sequences randomly to improve degree of randomness.

Fig. 3 is the diagrammatic sketch according to the processing of the supporting business Channel Transmission of embodiment of the present invention.The transmission of the communication information can occur with multiple form.Purpose for signal is described exemplary process at the communication information as MAC Address.As shown in Figure 3, the MAC index is offered processor 301 with output MAC ID sequence as input.In one embodiment, processor 301 provides coding, modulation and spread spectrum, and other communication process functions.In addition, signal transmitter system can relate to the transmission of control channel, and it comprises MAC Address and packet transmission format, and Packet Data Channel.Control channel by processor 303 based on this information for example transformat or the like generate.In addition, the information bit that comprises the regular length MAC Address can be encoded to be used for error protection by processor 305.Can select the length of MAC Address, thereby for example in system 100, hold the user of most probable number, and still minimize spending as small as possible.

Processor 301,303 and 305 output can be carried out time-multiplexed, code reuse or channeling by multiplexer 307, and wherein this multiplexer 307 generates composite services channels, and it comprises MAC ID sequence, control channel and data channel.For example, can be regarded as having comprised the MAC index information and carry out time-multiplexed control channel of being encoded in the lead code of system's 100 cocommutative groupings with data channel.

Usually, when traffic channel transmission occurs (is unit with frame, grouping, son grouping or time slot), control information is transmitted with the data channel that comprises the information bit (for example payload) that comes from the upper strata.As shown in Figure 3, transmission MAC ID is with the destination of identification transmission; Also transmit this transport format information and correctly receive this transmission to help receiver.After some is handled, this MAC id information is mapped to MAC ID sequence.

Traditionally, use quadrature or many bi-orthogonal sequences as MAC ID sequence.For example, in cdma2000 HRPD system, use 64 many bi-orthogonal sequences to support 7 bit mac ID.Can will be appreciated that when a large number of users was operated, it was inadequate using the conventional method of quadrature or many bi-orthogonal sequences in system.For example, 15 bit mac ID then will use 4096 many bi-orthogonal sequences if desired, and this needs very big expense.

By contrast, according to various occupation modes, method of the present invention adopts and shows the sequence of good correlation properties as the communication information (for example MAC ID) sequence.Can be contemplated that this mechanism can be used for specifying other information of replacing or adding as MAC ID, this information (for example " communication information ") can be information or the parameter that the support of any kind communicates by communication network.And this sequence does not need mutually orthogonal, but only needs the relevant enough little of them, thereby can ignore the influence of systematic function.Determine what is that the acceptable level of performance degradation partly depends on the application and service that system 100 is providing.Therefore, this method advantageously utilizes the performance degradation of minimal-overhead and nominal to hold a large number of users.

Fig. 4 is the diagrammatic sketch according to the exemplary MAC ID sequence of embodiment of the present invention.Waveform 401 expression random/pseudo-random sequences.Yet, can will be appreciated that any other sequence except random sequence or pseudo random sequence also can be used.From sequence, generate the MACID sequence.In this example, waveform 403 is 0 corresponding to MAC ID, and it has shift time 1.This waveform 403 is used to represent for example MAC ID sequence 00101110.Waveform 405 expression MAC ID are 1, and wherein shift time is 4.Waveform 405 is corresponding to MAC ID sequence 01110010.Similarly, MAC ID is that 2 (not being offset 11) can be represented that it has specified MAC ID sequence 00001010 by waveform 407.

This communication information (for example MAC ID) sequence also can be used for other purposes, such as among Fig. 5 A-Fig. 5 C explanation.

Fig. 5 A-Fig. 5 C is the control channel structure chart of use medium access control index (MAC ID) sequence of the various execution modes according to the present invention.After MAC ID is mapped to sequence, has different modes and use this sequence.Illustrative embodiments is to use this sequence that the code sign of other control informations is carried out scrambling, shown in Fig. 5 A.Also can expect other execution modes.For example, forward error correction (FEC) coded identification that can be used for other control informations of MAC ID sequence is carried out scrambling (Fig. 5 B).Replacedly, MAC ID sequence other control information bits of can be used for original to being in (promptly be not encoded, not processed or the like) form carry out scrambling (Fig. 5 C).

According to Fig. 5 A, circuit 501 comprises PN maker 501a, and it exports MAC ID sequence in response to MAC ID.This MAC ID sequence is used as scramble sequence.In this case, Cyclic Redundancy Check encoder 501b can for example transformat and other control informations of coded message.Utilize MAC ID sequence that scrambling is carried out in this output at adder 501c place.Then, the output of gained is fed to forward error correction (FEC) encoder 501d.

In the execution mode of Fig. 5 B, circuit 503 uses from the MAC ID sequence of PN maker 503a and carries out scrambling to exporting from the signal of FEC encoder 503b.Output is based on the CRC code signal from CRC encoder 503c.CRC encoder 503c, as utilize shown in the example of Fig. 5 A, can adopt various control informations as input to CRC encoder 503c.Adder 503d is based on the signal that is applied to generate from the MAC ID sequence of the signal of FEC encoder 503b scrambling.

Further, under the situation of Fig. 5 C, PN maker 505a produces MAC ID sequence, and it is used at adder 505b place scrambling being carried out in original (promptly not being encoded) control information.By CRC encoder 505c and FEC encoder 505d the signal of gained is encoded then.

In some embodiments, described signal transmitter system is used pseudo random sequence or the addressing of other sequences (having good association attributes) to support a plurality of AT are carried out.Advantageously, compare with the method for the MAC ID sequence that requires quadrature traditionally, this mechanism can be supported the AT than its greater number.
