Embodiment

This paper has described device, method and the software that is used in the multi-carrier communications systems with signaling transfer channel state information.In the following description, in order to explain, a plurality of specific detail have been illustrated so that the thorough of the embodiment of the invention is provided.Yet, for a person skilled in the art, clearly, can implement embodiments of the invention under the situation that does not have these specific detail or under the situation with equivalent arrangements.In other examples, the construction and device of knowing is illustrated with the form of structure chart, to avoid unnecessary fuzzy embodiments of the invention.

Though the present invention is discussed about cordless communication network (for example cellular system), but for the ordinary skill in the art, will be appreciated that the present invention is applicable to the communication system of any kind with multicarrier or multichannel ability (for example, Time Division Multiplexing and code division multiplexing (CDM) system).In addition, though each embodiment of the present invention describes under the background of data rate control (DRC) channel of three carrier systems, described embodiment can be extended to other multicarrier systems information relevant with other channel qualities, for example CQI (CQI).And, about the multicarrier on the forward link described signaling mechanism is described, can expect that described mechanism can be used to the multicarrier (described thus feedback information transmits at described forward link) on the reverse link.

Fig. 1 is the architecture view according to the multicarrier system of the embodiment of the invention, and described multicarrier system is configured to be provided for the signaling of channel condition information, and wherein said channel condition information comprises data-rate information.Wireless network 100 comprises one or more accessing terminal (AT) 101, and one of them AT 101 is illustrated as communicating by letter by air interface 103 with access network (AN) 105.According to an embodiment, system 100 provides third generation partner program 2 (3GPP2) cdma2000 HRPD (high rate packet data) version C (being also referred to as the cdma2000 evolution stage 2, DO version C) network.In another embodiment, system 100 also supports 3GPP Long Term Evolution (LTE) system.In cdma2000, AT 101 is equivalent to mobile radio station, and access network 105 is equivalent to the base station.

In order to explain, system 100 is as Nx DO system works (wherein N is an integer).In the NxDO system, reverse link need be N forward link 1x carrier feedback channels state information---data rate control (DRC) information for example.Described data rate control information has for example been stipulated the forward link data rate that AT can receive in the 1x carrier wave; In described 1xDO system, described data rate control value uses 4 bits to define.Therefore, for 3x DO system, need 12 bits; Expense significantly increases.Yet each embodiment of the present invention comes minimal overhead at the interior of the data rate control information that is used for a plurality of carrier waves in redundancy by utilizing.In one embodiment, system 100 can be implemented as overlapping N 1x network.

AT 101 provides data internuncial device for the user.For example, AT 101 can be connected to computer system, for example personal computer, personal digital assistant and the like, or support the cellular handset of data, services.Radio configuration comprises two kinds of mode of operation: 1x and multicarrier (that is, Nx).Multicarrier system adopts a plurality of 1x carrier waves to increase data rate to AT 101 (or mobile radio station) on described forward link.Therefore, different with the 1x technology, multicarrier system is worked on a plurality of carrier waves.In other words, AT 101 can visit a plurality of carrier waves simultaneously.In addition, reverse link can use a plurality of carrier waves.

AN 105 provides the internuncial network equipment of data between Packet Switch Data Network (for example Global Internet 113) and AT 101.AN 105 communicates by letter by Packet Control Function (PCF) 109 with packet data serving node (PDSN) 111.AN 105 or PCF 109 provide SC/MM (session control and mobile management) function, this function especially comprises the storage of HRPD session related information, whether execution terminal authentication process should be certified with definite AT 101 when the described wireless network of AT 101 visits, and the position of management AT 101.Title in June calendar year 2001 has further described PCF 109 among the 3GPP2 A.S0001-Av2.0 of " 3GPP2 AccessNetwork Interfaces Interoperability Specification ", and its content is completely integrated so far by reference.

In addition, AN 105 communicates by letter with AN-AAA (authenticating, authorize charging entity) 107, and wherein AN-AAA provides terminal authentication and authorization function for AN 105.

The air-interface standard of cdma2000 1xEV-DV (evolution-data and voice) and 1xEV-DO (data of evolution-optimization) has all stipulated to be used for to transmit the employed Packet Data Channel of packet on the air interface of forward link and reverse link.Wireless communication system 100 can be designed to provide various types of services.Described service can comprise point-to-point service or service-specific for example voice and grouped data, and data are sent to specific receiving terminal from transfer source (for example, base station) thus.Described service also can comprise a little serves to multiple spot (that is, multicast), or broadcast service, and data are sent to a plurality of receiving terminals (for example, AT 101) from transfer source thus.

In multiple access wireless communication system 100, communication between the user is carried out by one or more AT101, and the user's (accessing terminal) on wireless station communicates by send information signal to base station on reverse link with another user on another wireless station.AN 105 receives described information signal, and on the forward link described information signal is sent to AT station 101.Then, AN 105 sends described information signal to station 101 on the forward link.Described forward link is meant the transmission from AN 105 to wireless station 101, and described reverse link is meant the transmission of slave station 101 to AN 105.AN 105 is receiving on the reverse link from first user's data on the wireless station, and by public switch telephone network (PSTN) described data is routed to second user on the order wire website by land.In a lot of communication systems, for example, IS-95, wideband CDMA (WCDMA) and IS-2000, described forward link and described reverse link are assigned with frequency separately.

In exemplary embodiments, AN 105 comprises that HRPD (high rate packet data) (HRPD) base station is to support high data rate service.Should be understood that described base station access terminal and network between provide wireless frequency (RF) interface (carrier wave) by one or more transceivers.The HRPD that the HRPD base station provides independent only data (DO) carrier wave to be used for each sector (or sub-district) of being served described HRPD base station uses.The voice carrier that base station separately or carrier wave (not shown) are provided for voice application.It can be that DO accesses terminal that HRPD accesses terminal, and maybe can use the mode mobile terminal of voice-and-data service.In order to carry out data session, HRPD accesses terminal and is connected to the DO carrier wave to use the DO high-speed data service.Data session is by packet data serving node (PDSN) 111 control, the described HRPD of described PDSN route access terminal and the Internet between all packets.PDSN 111 has to the direct connection of Packet Control Function (PCF) 109, and PCF 109 links to each other with the base station controller (BSC) of HRPD base station.BSC is responsible for the processing of operation, maintenance and management, speech coding, rate adapted and the Radio Resource of described HRPD base station.Should be understood that described BSC can be separate nodes or can be and the ground that coexists, one or more HRPD base station.

In the 1x carrier wave, each HRPD base station can be served a plurality of (for example, three) sector (or sub-districts).Yet, should understand each HRPD base station and can mainly only serve single subdistrict (being called as comprehensive sub-district).Should be understood that also network 100 can comprise a plurality of HRPD base station, each one or more sector of HRPD base station services, the HRPD portable terminal can switch between the same HRPD sector of base station or between the different HRPD sector of base station simultaneously.For each sector (or sub-district), the Time Division Multiplexing forward link of sharing is separately further adopted in the HRPD base station, wherein under any circumstance independent HRPD portable terminal can the private family of coverlet packet service, and a plurality of portable terminal can be by multi-user's packet service.Forward link throughput rate is shared by all HRPD portable terminals.HRPD accesses terminal by its data rate control (DRC) being pointed to the sector and according to described channel condition (that is, based on the carrier/interface ratio (C/I) of channel) request forward data rate, thereby selects the serving sector (or sub-district) of described HRPD base station.

The continuous evolution of wireless communication technology, thus more high data rate and better service quality provided for various application with distinct characteristic.Cdma2000 HRPD (high rate packet data) (HRPD) standard is for example providing high data rate on the 1.25MHz carrier frequency.Described system provides only data (DO) service in a 1.25MHz carrier wave (1x), be called as 1x DO system sometimes.For providing of service further is provided, cdma2000 HRPD standard need be considered multi-carrier CDMA system.(be called as multicarrier HRPD (MC-HRPD) system or Nx DO system) in described system, (AT) 101 that access terminal can send and/or receiving data stream at a plurality of 1.25MHz wave bands.Especially, a kind of network configuration will be supported in three communications (for example, 3x DO system) on the 1.25MHz wave band.For example, system 100 is 3x DO systems, and described system can be used to be added on original HRPD system that is operated in the 1.25MHz wave band.Described scheme provides easily to the reusing of multiple technologies and assembly in the 1x DO system, and has therefore reduced development cost, and seamlessly transitting of from 1x DO system to multicarrier system (for example, 3x DO) is provided.

The advanced communication technology has been adopted in the further evolution of cdma2000 HRPD, for example OFDM (OFDM), multiple-input and multiple-output (MIMO) technology, space division multiple access (SDMA) and interference eliminated.Described system can be operated in 1.25MHz～20MHz frequency spectrum.Title in 3GPP22005 June 20 has been explained the scheme that is adjusted in a plurality of AT in the multi-carrier operation among the document C25-20050620-030 (its content is completely integrated so far by reference) of " Increased Forward Link MAC Indices ForMulti-Carrier Operation ".

Fig. 2 is the view of assembly of channel condition information that is used for being provided at Fig. 1 system of a plurality of embodiment according to the present invention.It should be understood that the channel condition information (for example, DRC information) that is used for these carrier waves is a height correlation if N (for example, 3) 1x carrier wave is positioned within the identical coherence bandwidth (for example, the 5MHz wave band).Therefore, the expense in the reverse link can be minimized by utilizing described correlation.Continue described exemplary 3x DO system, described 3 1x carrier waves can be called as C1, C2 and C3.The DRC that is used for described three carrier waves is represented as DRC1, DRC2 and DRC3 respectively.In wireless communication system 100, because carrier bandwidths is less than around the indicated coherence bandwidth of the environment of AT, some AT (for example AT 101) may experience flat decline.Because carrier bandwidths is greater than around the indicated coherence bandwidth of the environment of AT, other AT may experience frequency selective fading.If C1, C2 and C3 are positioned within the coherence bandwidth for AT 101, then the channel condition in these carrier waves may height correlation.Therefore, DRC 1, DRC 2 and DRC 3 comprise some redundancy.

Therefore, AT 101 needn't send three all complete DRC to AN 105, and can utilize described redundancy and send less bit and obtain the effectiveness much at one with three complete DRC.On the other hand, if the distance between C1, C2 and the C3 much larger than coherence bandwidth for another AT, then the correlation between these carrier waves is just very little.In this case, can guarantee to be three complete DRC of this AT report.

As shown in Figure 2, processor 201 receives about the information of carrier wave C1, C2 and C3 and comprises that correlation logic 201a (that is correlator) is to determine the correlation of these carrier waves.Perhaps, processor 201 can realize that spectrum position logic 201b is to determine the position of carrier wave.Memory 203 memory channel architecture 203a, for example, the DRC channel format; Channel architecture form 203a also can be called as reporting format.In the exemplary embodiment, the DRC channel is used for indicating selected serving sector and needed data rate on forward traffic channel to AN105 by the AT 101 of system 100.In addition, memory 203 can comprise the system configuration parameter 203b of the various characteristics of regulation multicarrier system 100.

Select logic 205 and processor 201 collaborative works,, from memory 203, select suitable form 203a with the correlation or the spectrum of carrier position of the carrier wave determined based on processor 201.Encoder 207 also is provided for encodes to the corresponding DRC report with selected form 203a.

According to each embodiment of the present invention, select the different-format of DRC channel based on the correlation between the configuration of Nx DO system and N the 1x carrier wave, so that the forward link advantage of maximum channel sensitive scheduling minimizes described reverse link expense simultaneously.So, can be defined as the multiple form 203a of the DRC channel of N carriers carry DRC information.Should be understood that and to use other channel condition informations, for example channel quality information (for example, the carrier/interface ratio of channel (C/I)).

As three carrier waves are example formats of (for 3x DO system) situation independently, and form A (complete report form) reports three complete DRC values, and it uses 12 bits.In the exemplary embodiment, these three DRC values are encoded with higher coding gain and better error protection in the situation of the DRC channel that separates that obtains to be compared to three carrier waves together by encoder 207.

As the example format under the situation that is height correlation of three carrier waves wherein, form B (variance reports form) reports DRC2, Δ DRC1=(DRC1-DRC2), and Δ DRC3=(DRC3-DRC2).For the DO system, DRC2 can adopted value 0x0,0x1 ... 0xe}.For example, suppose Δ DRC1 and Δ DRC3 all from 1,0, value among the+1}, whole combinations of DRC2, Δ DRC1 and Δ DRC3 provide different situations in 125.Accordingly, for form B, 7 bits are enough.Yet, it will be appreciated that extra form can define as required based on application-specific.Described form selection course will describe in further detail hereinafter.

Fig. 3 is a flow chart of determining the process of reporting format based on the correlation of multicarrier according to an embodiment of the invention.In step 301, correlation logic 201a determines the correlation between the carrier wave.In the exemplary embodiment, described correlation (in the system of three carrier waves) can be determined by following correlation matrix:

$R=\left[\begin{array}{ccc}{R}_{11}& R_{12}& R_{13}\\ R_{21}& R_{22}& R_{23}\\ R_{31}& R_{32}& R_{33}\end{array}\right],$

R wherein _IjCorrelation between expression carrier wave i and the carrier wave j, and R _Ii=1.0, R _Ij=R ^* _Ji,  i, j.After the correlation that AT 101 measures between described three carrier waves, AT 101 can determine the form of described DRC channel based on described correlation.

By step 303, next processor 201 determines whether described carrier wave is independently.If described carrier wave is independently, select logic 205 to select the complete report form so, as shown in step 305.Otherwise execution in step 307 determines whether described carrier wave is height correlation; If, with regard to selection differences reporting format (step 309).

AT 101 and AN 105 can transmit the selection of DRC channel format by signaling message.In alternative embodiment, the form of DRC channel can be determined based on described spectrum of carrier position, and is as mentioned below.

Fig. 4 is a flow chart of determining the process of reporting format based on the spectrum of carrier position according to an embodiment of the invention.In step 401, spectrum position logic 201b determines the spectrum of carrier position.So this positional information is used to select suitable form, as in the step 403.For example, if three carrier waves are positioned in the predetermined wave band (for example, the 5MHz wave band), show that about described spectrum of carrier information they are height correlations so; Therefore, form B (for example difference DRC report) is selected.Otherwise form A (for example, complete DRC report) is selected.

About downward compatibility, data rate control channel can send on reverse link.Therefore, consider that the AT that uses this DRC channel architecture can exist simultaneously with original moving body in identical systems, the system of Fig. 1 is backwards-compatible.

Process that Fig. 5 A and 5B encode according to each embodiment of the present invention, to the report relevant with channel status respectively and the flow chart of consulting the process of new reporting format (or structure of feedback channel).Though some embodiment of the present invention explains with regard to three carrier systems, should recognize that described each embodiment can be easy to expand to the N carrier system.For example, described carrier wave can be divided into a plurality of groups (as in the step 501), and wherein each group comprises a plurality of carrier waves.In each group, select one and represent carrier wave to report complete DRC (step 503), and other all carrier waves in described group are by the difference of their DRC of step 505 report with respect to the DRC of described representative carrier wave.

In step 507, determine whether carrier wave is independent.If they are independently, then the DRC of these groups report can be encoded with being separated, and as separated channels, for example uses CDM, TDM, OFDM (OFDM) or other multiplex techniques to send (as step 509 and 511).Otherwise according to one embodiment of present invention, described DRC report also can be sent out (by step 513 and 513) by combined coding and as individual channel, with maximization coding and diversity gain.

It should be noted that (for example, the DRC channel) structure or reporting format may change described feedback channel, shown in Fig. 5 B in communication process.Whenever AN 105 or AT 101 determines, as in the step 551, when being fit to change the structure of described DRC channel (or described reporting format), by step 553, AN 105 or AT 101 just can consult the new construction of DRC channel (or reporting format) by signaling message.Then, realize the structure after the new negotiation, as in step 555.Because described variation may be very slow, can be ignored by the expense that signaling causes.For example, following situation can trigger request to change the DRC channel architecture: (1) allocation of carriers/cancellation distributes, the variation that (2) group is arranged, and (3) mutually on the same group in correlation variation between the carrier wave.

According to each embodiment, the present invention utilizes the correlation between a plurality of carrier waves to reduce expense in the channel condition information feedback.Can obtain following summary easily.For example, cdma2000 HRPD system is used as example system, but each embodiment of the present invention can be applied to the system that other use multicarriers---for example CDMA multiple carrier, OFDM-CDMA, ofdm system, or the like.Equally, data rate control channel is reserved as the exemplary channel of channel condition information; Yet, can expect the channel status information reports that can utilize other types, for example carrier/interface ratio (C/I) (or other channel quality informations).

The those of ordinary skill of the industry can recognize that the described process that data rate control and/or channel quality signaling are provided can (for example pass through software, hardware, general processor, digital signal processor (DSP) chip, application-specific integrated circuit (ASIC) (ASIC), field programmable gate array (FPGA), or the like), firmware or above-mentioned combination realize.The described example hardware that is used to finish described function is described hereinafter.
