For each CDMA Channel, the R-ACKCH bit that signal point mapping unit 432 will be used for this CDMA Channel is mapped as+and 1 ,-1 or 0.Walsh capping unit 434 utilizes the 8-chip walsh code that is assigned to this CDMA Channel that mapping value is covered, and the sequence that comprises eight symbols is provided.436 pairs of 8-symbol sebolic addressings of repetitive triplicate generates the sequence that comprises 24 symbols that is used for this CDMA Channel.In each time slot, adder 438 will be respectively from seven 24-symbol sebolic addressings addition of the repetitive 436a to 436g that is used for CDMA Channel 0 to 6, and provide 24 modulation symbols corresponding to this time slot.These modulation symbols are further processed and send.
Fig. 4 B and Fig. 4 C illustrate exemplary R- ACKCH structure 420 and 430, its support a plurality of R-ACKCH and with current R-ACKCH structure 410 back compatibles shown in Fig. 4 A.If a CDMA Channel is received, then utilizes walsh code W 0 4Or W 0 8The R-ACKCH bit that is used for this CDMA Channel is handled, and the R-ACKCH bit that is used for all other CDMA Channel is set to VB vacancy bit.Thereby adder 428 or 438 output will be identical with the output of repetitive 412 among Fig. 4 A.Can send the R-ACKCH bit that is used for additional CDMA Channel by utilizing other walsh code, support described additional CDMA Channel.According to the length of walsh code, repetition factor is reduced to 6 or 3 from 24.
R-ACKCH structure shown in Fig. 4 B and Fig. 4 C can utilize the hardware that is designed to R-ACKCH structure shown in Fig. 4 A to recover the R-ACKCH bit.This hardware can generate 24 receiving symbols for R-ACKCH in each time slot.Can carry out in software and/or firmware and utilize walsh code that described 24 receiving symbols are separated the operation of covering, this can reduce upgrading base station to support the influence of multi-carrier operation.
Also can use other structure to realize a plurality of R-ACKCH, this will be located within the scope of the present invention.For example, a plurality of R-ACKCH can be by time division multiplexing, and can send in the different interval of a given time slot.

In another program, the new R-CQICH structure that can support for the CQI feedback of a plurality of FL carrier waves has been described.When terminal can send on single RL carrier wave, a plurality of FL carrier waves in monitoring given group, as shown in Figure 3.Described a plurality of FL carrier wave may observe different channel conditions (for example, different fading characteristics), and may obtain different received signal qualities in end.Wish that terminal can provide CQI feedback for the FL carrier wave that distributes as much as possible, the system that makes can select suitable being used to send the suitable speed of FL carrier wave and each selected FL carrier wave of data.If system configuration comprises single RL carrier wave, then terminal can send the CQI feedback via single RL carrier wave for all FL carrier waves on single R-CQICH.R-CQICH can be designed to have the ability that transmits the CQI feedback for one or more FL carrier waves.
In cdma2000 revised edition D, R-CQICH can operate with one of two patterns in each 1.25ms frame (perhaps time slot), and described two patterns are integrated pattern or diversity mode.In integrated pattern, on R-CQICH, send the complete CQI report that comprises the 4-bit value.This 4-bit CQI value has been passed on the received signal quality of a CDMA Channel.In diversity mode, on R-CQICH, send the difference CQI report that comprises the 1-bit value.This 1-bit CQI value has been passed on for a CDMA Channel, the difference of received signal quality between the current and previous time slot.Can be according to described complete CQI of the described generation of TIA/EIA IS-2000.2 and difference CQI report.
Fig. 5 A is illustrated in the block diagram of R-CQICH structure 510 used among the cdma2000 revised edition D.For CDMA Channel, be integrated pattern or diversity mode according to what select, can in each 1.25ms frame (perhaps time slot), generate 4-bit or 1-bit CQI value.4-bit CQI value is also referred to as CQI value symbol.1-bit CQI value is also referred to as difference CQI symbol.Block encoder 512 uses (12,4) block code (block code) that 4-bit CQI value is encoded, and has the code word of 12 symbols with generation.514 pairs of 1-bits of symbol repetitive CQI value repeats 12 times, to generate 12 symbols.Switch 516 is perhaps selected the output of repetitive 514 for the output of integrated pattern selection block encoder 512 for diversity mode.
Can report be covered by the walsh code that utilization is assigned to certain base station, send the CQI report to this base station.Walsh capping unit 518 receives and is used for selectedly providing the 3-bit Walsh codes of serving base station to terminal, and generates a corresponding 8-chip walsh sequences.Unit 518 also repeats the 8-chip walsh sequences 12 times, and 96 Walsh chips are provided in each time slot.Modulo 2 adder 520 will carry out addition from the symbol of switch 516 and the output of Walsh capping unit 518, and 96 modulation symbols are provided in each time slot.Walsh capping unit 518 and adder 520 are used for the 3-bit Walsh codes of selected base station, and each symbol from switch 516 is covered efficiently.Channel point map unit 522 is mapped as each modulation symbol+1 or-1 value.Walsh capping unit 524 utilizes walsh code W 12 16Each mapping value from unit 522 is covered, and output symbol is provided, this output symbol is further processed and sends on R-CQICH.
New R-CQICH structure can be supported integrated pattern or diversity mode for one or more FL carrier waves.In one embodiment, in the TDM mode, in different time slots, send complete CQI report for the different FL carrier waves in the group.In one embodiment, for given time slot, will carry out combined coding for the difference CQI report of all the FL carrier waves in the group, and in this time slot, send together.The independent coding of the combined coding of difference CQI report being compared single difference CQI report is more efficient.Repetition in the square frame 514 can be by coding replacement more efficiently.
Fig. 5 B illustrates the block diagram of embodiment that the new R-CQICH structure 530 of CQI feedback can be provided for a plurality of CDMA Channel.In this embodiment, block encoder 532 utilizes (12,4) block code that the 4-bit CQI value that is used for a CDMA Channel is encoded, and has the code word of 12 symbols with generation.(12, N) block code is carried out combined coding to N the 1-bit CQI value that is used for N CDMA Channel, has the code word of 12 symbols with generation in block encoder 534 utilizations.Block encoding rate (R) equals input bit quantity/output amount of bits, perhaps, for (12,4) block code, R=4/12, for (12, N) block code, R=N/12.Different encoding rates generates different amount of redundancys, and needs different received signal qualities to carry out reliable reception.Therefore, according to the quantity of CDMA Channel N, different amount of transmission power is used for code word from block encoder 534.
Switch 536 is perhaps selected the output of block encoder 534 for the output of integrated pattern selection block encoder 532 for diversity mode.Walsh capping unit 538, adder 540, signal point mapping unit 542 and Walsh capping unit 544 adopt respectively with Fig. 5 A in for unit 518,520,522 and 524 described identical modes, to handling from the symbol of switch 536.Walsh capping unit 544 provides output symbol, and this output symbol is further processed and sends on R-CQICH.
The block encoding of encoder 534 can be with following matrix notation:
y= u GEquation (1)
Wherein, u=[u 0u 1U K-1] be the capable vector of 1 * k corresponding to 1-bit CQI value sequence, u 0It is vector uIn first input bit,
y=[y 0y 1Y N-1] be the capable vector of 1 * n corresponding to encoder output code word, y 0Be the output of first among vectorial y bit, and
GIt is the k * n generator matrix that is used for block encoding.
Block code is specified in its generator matrix usually.Can be at the different block code of from 2 to 7 different N value defined, to support nearly 7 CDMA Channel.Can select the block code corresponding to each N value, to obtain good performance, it can be measured by the minimum range between the code word.Table 2 is listed the exemplary block code corresponding to N=2 to 7.Block code in the table 2 has the possible minimum range of the maximum between the code word of linear block code.
Table 2
May repeat corresponding with the performed 12 * bit in unit among Fig. 5 A 514 corresponding to the block encoding of N=1.In the embodiment shown in the table 2, (12,2) block code comprises then carries out (3,2) block code that 4 * sequence repeats to it.The generator matrix of (12,4) block code that is used for encoder 534 is identical with the generator matrix of (12,4) block code that is used for encoder 512 and 532.(12,2) in the table 2, (12,3), (12,4), (12,5), (12,6) and (12,7) block code have 8,6,6,4,4 and 4 minimum range respectively.Block code for being used for difference CQI report also can define and use other generator matrix.
Fig. 5 B illustrate support for the CQI of a plurality of CDMA Channel feedback and with the exemplary R-CQICH structure 530 of current R-CQICH structure 510 back compatibles shown in Fig. 5 A.If only a CDMA Channel is received, then can utilize (12,4) block code is handled the complete CQI report of this CDMA Channel, can utilize 12 * bit to repeat difference CQI report is handled, and the output of Walsh capping unit 544 will be identical with the output of Walsh capping unit 524 among Fig. 5 A.Can in different time-gap, send for complete CQI report and (2) of CDMA Channel by (1) and in identical time slot, unite the difference CQI report of transmission, support the CDMA Channel of adding for CDMA Channel.
R-CQICH structure shown in Fig. 5 B can be come the complete sum difference CQI report of a plurality of CDMA Channel is recovered by the R-CQICH structure shown in Fig. 5 A is carried out minor alteration.The hardware that is used for physical layer can be to the decoding of complete CQI report carrying out piece.Can be at the demultiplexing of medium access control (MAC) layer execution to the complete CQI report of dissimilar CDMA channels.Can carry out the piece decoding that difference CQI is reported at physics or MAC layer.
Also can use the R-CQICH of other structure realization for a plurality of CDMA Channel, this will be located within the scope of the present invention.For example, the complete CQI report for a plurality of CDMA Channel can send by block encoding and in identical time slot.As another example, can in a time slot, send for the difference CQI report of the child group of a plurality of CDMA Channel.
Terminal can be assigned with a plurality of FL and RL carrier wave set, as shown in Figure 3.For each carrier wave set, the R-CQICH that sends on the RL carrier wave in group can transmit the CQI report for the FL carrier wave in the group, as described in Fig. 5 B.Can send the CQI report with multiple mode.
Fig. 6 A to Fig. 6 E illustrates some exemplary transmission on the R-CQICH.In these figure, complete CQI report is by higher box indicating, and difference CQI reports by shorter box indicating.The height of square frame shows the amount of transmission power that is used to send the CQI report roughly.The FL carrier wave that numerical value indication in each square frame is reported by the CQI report that sends in this square frame.
Fig. 6 A is illustrated in the transmission that complete CQI and difference CQI for two FL carrier waves 1 and 2 on the R-CQICH report.In this example, in a time slot, send complete CQI report for FL carrier wave 1, then, in the time slot of some quantity, send difference CQI report, then for FL carrier wave 1 and 2, in a time slot, send complete CQI report for FL carrier wave 2, then, in the time slot of some quantity, send difference CQI report, then for FL carrier wave 1 and 2, in a time slot, send complete CQI report, by that analogy for carrier wave 1.Generally speaking, can send with arbitrary velocity, can use identical or different report speed for a plurality of FL carrier waves for the complete CQI report of each FL carrier wave.In one embodiment, send complete CQI report in (for example, first) time slot in each 20ms frame, in all the other 15 time slots of this frame, send difference CQI report.Complete CQI report for FL carrier wave 1 and 2 can replace as shown in Fig. 6 A, perhaps can otherwise carry out multiplexing.
Fig. 6 B is illustrated in the transmission that the complete CQI for two FL carrier waves 1 and 2 on the R-CQICH reports.In this example, in a time slot, send complete CQI report, then, in next time slot, send complete CQI report, then, in next time slot, send complete CQI report, by that analogy for FL carrier wave 1 for FL carrier wave 2 for FL carrier wave 1.
Fig. 6 C is illustrated in the transmission for the complete CQI of three FL carrier waves 1,2 and 3 and difference CQI report on the R-CQICH, and wherein repetition factor is 2 or REP=2.In this example, in preceding two time slots of 20ms frame, send complete CQI report for FL carrier wave 1, then, in each all the other time slot of this frame, send for FL carrier wave 1,2 and 3 difference CQI report, then, in preceding two time slots of next 20ms frame, send complete CQI report for FL carrier wave 2, then, in each all the other time slot of this frame, send for FL carrier wave 1,2 and 3 difference CQI report, then, in preceding two time slots of next 20ms frame, send complete CQI report for FL carrier wave 3, then, in each all the other time slot of this frame, send for FL carrier wave 1,2 and 3 difference CQI report, then, in preceding two time slots of next 20ms frame, send complete CQI report, by that analogy for FL carrier wave 1.Similar to complete CQI report, can in two continuous time slot, send difference CQI report, perhaps, can in single time slot, send.
Fig. 6 D is illustrated in the transmission that the complete CQI for three FL carrier waves 1,2 and 3 on the R-CQICH reports, wherein repetition factor is 2.In this example, in two time slots, send complete CQI report for FL carrier wave 1, then, send complete CQI report below in two time slots for FL carrier wave 2, then, send complete CQI report below in two time slots, then for FL carrier wave 3, send complete CQI report below in two time slots, by that analogy for FL carrier wave 1.
Fig. 6 E is illustrated in the transmission for the complete CQI report of three FL carrier waves 1,2 and 3 on the R-CQICH, and wherein repetition factor is 2 and has two and switch time slots.In this example, the complete CQI that sends for FL carrier wave 1,2 and 3 with the same way as with above-mentioned Fig. 6 D description reports.But last four time slots of 20ms frame are used for sending switching time slot map (switch slot pattern) (being expressed as " s " at Fig. 6 E), and it is the message that switches to new serving BS.
As shown in Fig. 6 A to Fig. 6 E, cause reducing along with the increase of FL number of carriers in the group for the report speed of the complete CQI report of a given FL carrier wave for the time division multiplexing of the complete CQI report of all FL carrier waves.For example, if a group comprises 7 FL carrier waves, then for each FL carrier wave, complete CQI report can send with per 7 * 20ms=140ms speed once.Combined coding for the difference CQI of all FL carrier waves report causes the report speed of difference CQI report to be independent of the quantity of FL carrier wave in the group, not influenced by it.When switching to a new sub-district, switch the complete CQI report of time slot map " perforation (puncture) " (perhaps replacing).This perforation may not can similarly influences all FL carrier waves.In the example shown in Fig. 6 E, switching time slot map influences FL carrier wave 1 and 2, but does not influence FL carrier wave 3.
In one embodiment, terminal selection single base station carries out the transfer of data on the forward link.Can based on end for main FL carrier wave, all FL carrier waves that distributed or distribute the measured received signal quality of child group of FL carrier wave, this base station is selected.The R-CQICH that is used for all RL carrier waves uses Walsh to cover to selected base station, points to same sub-district thus.To the selection of single base station avoided on the forward link out-of-sequence transmission and to the potential negative effect of radio link protocol (RLP).On forward direction, rlp frame locates to carry out precommpression (pre-pack) at base station controller (BSC) usually, is forwarded to the base station then to be transferred to terminal.Therefore, can be by send the out-of-sequence transmission of avoiding rlp frame from single base station.
In another embodiment, the transfer of data on the forward link is carried out in the optional majority of a terminal base station.As mentioned above, because for different FL carrier waves, fading characteristic may be different, this embodiment makes terminal to select suitable base station for each FL carrier wave or every group of FL carrier wave, and this can improve entire throughput.
3. R-PICH
Wish to reduce the reverse link expense of transfer of data on the forward link.Can achieve this end by the single carrier wave set that comprises a plurality of FL carrier waves and single RL carrier wave for terminal distribution.Data can send on a plurality of FL carrier waves, and affirmation and CQI feedback can send on single RL carrier wave efficiently.
Under specific circumstances, can use a plurality of RL carrier waves.For example, above-mentioned new R-ACKCH and R-CQICH structure may not supported in the base station.In this case, each FL carrier wave can with support to be used for the R-ACKCH of this FL carrier wave and the RL carrier wave of R-CQICH is associated.
In cdma2000 revised edition D, terminal sends pilot tone on R-PICH, detects rl transmission to help the base station.If distribute single RL carrier wave, then pilot-frequency expense with all FL carrier waves that this RL carrier wave is associated between share.But, if distribute a plurality of RL carrier waves, and if on each RL carrier wave, send R-PICH to support R-ACKCH and R-CQICH, then for the low data rate on the reverse link, pilot-frequency expense may be very significant.Can realize the reduction of pilot-frequency expense by using control-maintenance pattern.
Fig. 7 illustrates the full pilot tone on the R-PICH and the transmission of gating pilot tone.Full pilot tone is the pilot transmission in each time slot, and its pilot tone gating speed is 1.1/2 and 1/4 pilot tone gating speed is supported in the control that defines in cdma2000 revised edition D-maintenance pattern (perhaps abbreviating " revised edition D control-maintenance pattern " as).As shown in Figure 7, the gating pilot tone is the pilot transmission in some time slot, and perhaps more specifically, the pilot tone gating speed for 1/2 is carried out pilot transmission every a time slot, and for 1/4 pilot tone gating speed, per four time slots carry out pilot transmission.
In cdma2000 revised edition D, usually, the base station places control-maintenance pattern by send the 3rd layer of message after control-maintenance timer expiry with terminal.For example, if in a certain period of time, the base station does not receive any data and does not send any data to terminal from terminal, and then the base station can send the 3rd layer of message to terminal, to be placed on control-maintenance pattern.If have new data to arrive base station or end, then trigger from control-maintenance mode shifts.If new data incoming terminal place is arranged, then terminal is spontaneously come out from control-maintenance mode shifts, and beginning sends full pilot tone and data on reverse link.The base station detects terminal and comes out from control-maintenance mode shifts, and the data that send with full pilot tone are decoded.If there is new data to arrive the place, base station, then the base station is at first waken terminal up by send MAC message on F-PDCCH.Under control-maintenance pattern, terminal is not handled F-PDCH, so that save power.
A lot of application all have the characteristic of asymmetric data business, and these application may need a plurality of F-PDCH on a plurality of FL carrier waves.Therefore, a plurality of reverse pilot may be sent, to support a plurality of F-PDCH on a plurality of RL carrier waves.Except reverse pilot, the business on the auxiliary RL carrier wave may include only CQI report on the R-CQICH and the affirmation on the R-ACKCH.In this case, the use of control-maintenance pattern can reduce the reverse link expense on the auxiliary RL carrier wave significantly.
But because underlying cause, revised edition D control-maintenance pattern does not directly apply to auxiliary RL carrier wave.At first, under revised edition D control-maintenance pattern, terminal is not decoded to F-PDCH.The second, terminal needed to come out from revised edition D control-maintenance mode shifts before sending on the R-ACKCH, and need be from the 3rd layer of message of base station the terminal setting is returned control-maintenance pattern.Do not wish all must send the 3rd layer of message when each terminal sends on R-ACKCH.In addition, because the base station sends the 3rd layer of message afterwards at control-maintenance timer expiry (approximately being the hundreds of millisecond usually), thereby on reverse link, send full pilot tone at this time durations.
In another program, definition " assisting " control-maintenance pattern is to use on auxiliary RL carrier wave.In one embodiment, the difference of assist control-maintenance pattern and revised edition D control-maintenance pattern is:
Terminal can be handled F-PDCH during assist control-maintenance pattern,
Terminal can send affirmation on R-ACKCH, and need not from assist control-maintenance pattern transfer to be shifted out,
If F-PDCH is successfully decoded, then terminal can spontaneously send full pilot tone and affirmation on R-ACKCH, and
Terminal can be proceeded the pilot tone gating after finishing the R-ACKCH transmission.Also can use difference and/or other characteristic to define assist control-maintenance pattern.
In order to reduce the pilot-frequency expense on the reverse link, revised edition D control-maintenance pattern can be used on main RL carrier wave, and assist control-maintenance pattern can be used on each auxiliary RL carrier wave.Two versions of control-maintenance pattern can be supported the efficient operation of a plurality of RL carrier waves in multi-carrier operation.
In one embodiment, can define control-maintenance pattern independently to each RL carrier wave.Following situation may appear:
Main RL carrier wave is in activity pattern, and the auxiliary RL carrier wave of any amount may be in control-maintenance pattern.Terminal can be handled the F-PDCH of auxiliary RL carrier wave, and can send on R-ACKCH, and need not to leave control-maintenance pattern.
All RL carrier waves all are in control-maintenance pattern.Terminal is not handled F-PDCH, and does not send on R-ACKCH under the situation of not leaving control-maintenance pattern.This is a kind of power saving mode.
4. R-REQCH
Terminal can send various types of information to the base station on R-REQCH.The trigger that is used for sending R-REQCH message among the cdma2000 revised edition D also can be reserved as the trigger of the R-REQCH message that sends multi-carrier operation.In one embodiment, terminal sends R-REQCH message on main RL carrier wave, to transmit service related information to the base station.For the transfer of data on all RL carrier waves, can be every service and keep a buffer.Service related information can comprise buffer sizes and watermark intersection (watermark crossing).In one embodiment, terminal sends R-REQCH message on main and auxiliary RL carrier wave, is used for the power headroom scope (headroom) of these RL carrier waves with transmission.The power report triggering device of each RL carrier wave can be used to send R-REQCH message, is used for the power headroom scope of this RL carrier wave with transmission.
5. Scheduling
Can dispatch terminal with multiple mode, to transmit at forward direction and the enterprising line data of reverse link.Can carry out centralized scheduling to a plurality of carrier waves, perhaps each carrier wave be carried out distributed scheduling.In one embodiment, terminal is dispatched, to transmit at the enterprising line data of a plurality of carrier waves with centralized scheduler.Centralized scheduler can be supported dispatching algorithm flexibly, and it can use CQI information on all carrier waves, to improve throughput and/or desired service quality (QoS) is provided.In another embodiment, distributed scheduler is used for each carrier wave, and on this carrier wave, terminal is dispatched.The distributed scheduler that is used for different carrier can be operated independently of one another, and can reuse the existing dispatching algorithm of cdma2000 revised edition D.
Terminal can be assigned with a plurality of carrier waves, and it can be by individual channel card or a plurality of channel card support at place, base station.If a plurality of FL carrier waves are handled by different channel card, then can there be the channel card communication delay, it may be about several milliseconds.Although should time-delay very little, it be usually greater than 1.25ms, and this is time that R-ACKCH is decoded, the preferred time that R-CQICH is decoded and the time that the new biography on the F-PDCH is input into the row scheduling.
If a plurality of channel card are used for different FL carrier waves, then centralized scheduler may cause additional scheduler latency.This additional delay comprises two parts.First is the R-CQICH time-delay of transmitting the CQI feedback from the channel card of handling the reverse link decoding to centralized scheduler.Second portion is that selected encoder packet arrives the time-delay of handling F-PDCH channel transmitted card.Additional delay may influence throughput of system, and still, its influence should be restricted to the speed and the channel model of relative narrower scope.
For example, if reverse link decoding and forward link transmissions stick into the row processing by individual channel, then distributed scheduler may not can cause above-mentioned for the described additional delay of centralized scheduler.If there is not subcarrier in the carrier wave set, then this mode is suitable for.But, if on each channel card, all realize distributed scheduler, then may keep an independently buffer, so that data can be total to the position with scheduler for each channel card.This card buffer may be very little, and bigger buffer may be positioned at the place, base station.Distributed scheduler should have enough data so that business is dispatched.The time-delay that obtains excessive data from bigger buffer may be about several milliseconds.The card buffer sizes should be considered the highest possible aerial data rate, to avoid buffer underflow.Although the buffer at channel card place may be less relatively, the reception of the rlp frame of end is likely out of order.Therefore, may use long detection window for rlp frame.Because traditional early stage NAK technology does not consider that Business Stream may be just out of order in first transmission, so it is unpractical.Time-delay detection window long among the RLP may produce bigger influence to TCP.Can use a plurality of RLP examples, one of for example every F-PDCH, but it may cause the out of order arrival of TCP segmentation.
Rlp frame carries out precommpression at the BSC place usually, and by affix MUX expense.In cdma2000, each rlp frame (comprising the MUX expense) comprises 384 bits, and it is identified by the 12-bit sequence number.Cdma2000 RLP head is 12 bits of rlp frame serial number assignment, and it is used in end rlp frame being recombinated.Suppose the big or small less of rlp frame, then this sequence space may not be suitable for two-forty, for example available speed in the multicarrier configuration.In order to support high data rate with existing RLP, rlp frame can be made the additional 12 bit sequence spaces that are used for the segmentation rlp frame to be reused by segmentation in advance.Owing to need not rlp frame is carried out precommpression, sequence space does not become the problem on the reverse link.
Call establishment that can realization multi-carrier operation as described below.Terminal is obtained system information from forward direction synchronizing channel (F-SYNCH), and obtains Overhead Message from Forward Paging Channel (F-PCH) or the forward broadcast control channel (F-BCCH) that sends at main FL carrier wave.Then, terminal can make a call on main RL carrier wave.The base station can be via the extended channel assignment message (ECAM) that sends on main FL carrier wave to the terminal distribution Traffic Channel.The terminal to acquire service channel, and transfer to travelling carriage control traffic channel state, this is a kind of state in the travelling carriage mode of operation among the cdma2000.In one embodiment, only to main carrier wave defining operation state.Then, a plurality of FL and RL carrier wave can be distributed via for example general switch indicating information (UHDM) in the base station.When the Traffic Channel on the new carrier wave was carried out initialization, the base station can be after sending UHDM, and beginning is gone up at forward direction public power control channel (F-CPCCH) and sent order.Terminal can begin to send R-PICH when receiving UHDM.Terminal can send handoff completion message (HCM) to the base station on main RL carrier wave, obtain F-CPCCH with expression, and wherein HCM is cdma2000 the 3rd a layer protocol message.
6. Flow process and system
Fig. 8 illustrates the embodiment that terminal is the performed processing of multi-carrier operation 800.Terminal receives the distribution (square frame 812) to a plurality of forward links (FL) carrier wave and at least one reverse link (RL) carrier wave.Terminal can be in a plurality of FL carrier waves one or more on receive transfer of data (square frame 814).For each FL carrier wave, terminal can be carried out demodulation sign indicating number (square frame 816) respectively to the transfer of data that is received.Terminal also can send data (square frame 818) at least one RL carrier wave.Can be based on multiple factor, for example the availability of system resource, the data volume that will send, channel conditions or the like are dispatched terminal, to transmit at forward direction and/or the enterprising line data of reverse link.
Terminal can send the RL signaling of appointment on main RL carrier wave, wherein can specify main RL carrier wave (square frame 820) from least one RL carrier wave.Terminal can receive the FL signaling of appointment on main FL carrier wave, wherein can specify main FL carrier wave (square frame 822) from a plurality of FL carrier waves.For example, terminal can make a call on main RL carrier wave, and can receive the signaling that is used for call setup on main FL carrier wave.Terminal can select to be used for carrying out on the forward link the base station of transfer of data based on the received signal quality of main FL carrier wave.
A plurality of FL carrier waves and at least one RL carrier wave can be arranged at least one group.Each group can comprise at least one FL carrier wave and a RL carrier wave, as shown in Figure 3.Terminal can receive grouping on the FL carrier wave in each group, and can send the affirmation for receive grouping via the RL carrier wave in this group.Terminal also can send the CQI report for the FL carrier wave in this group via the RL carrier wave in each group.A FL carrier wave in each group can be designated as group main FL carrier wave (group primary FL carrier).Terminal can receive the signaling of the RL carrier wave that is used for each group via the main FL carrier wave of group.
Fig. 9 illustrates the embodiment of the processing 900 that is used to send affirmation.Terminal receives (for example, the grouping (square frame 912) on F-PDCH) of a plurality of data channels send via a plurality of forward links (FL) carrier wave.Terminal is determined the affirmation (square frame 914) for the grouping that receives on data channel.The terminal utilization is assigned to the orthogonal code (for example, walsh code) of each data channel channelizing is carried out in the affirmation of this data channel, with the symbol sebolic addressing (square frame 916) that generates this data channel.Terminal repeats repeatedly (square frame 918) with the symbol sebolic addressing of each data channel.Terminal generates acknowledgement channel (for example, modulation symbol R-ACKCH) (square frame 920) based on the symbol sebolic addressing that is repeated of a plurality of data channels.
The quantity of data channel is configurable.For example, because the back compatible of cdma2000 revised edition D if only a data channel is sent affirmation, then can be used complete zero or complete one orthogonal code.If the quantity of data channel less than first value (for example four), then can be used the orthogonal code of first length (for example, four chips).If the quantity of data channel is equal to, or greater than first value, then can use the orthogonal code of second length (for example, eight chips).Repetition factor also may depend on the quantity of data channel.
Figure 10 illustrates the embodiment of the processing 1000 that is used for transmitting channel quality indication (CQI) report.Terminal obtains the complete CQI report for a plurality of forward links (FL) carrier wave, the received signal quality (square frame 1012) of a FL carrier wave of each complete CQI report indication.The terminal utilization is used for the orthogonal code (for example, walsh code) of selected base station to each complete CQI report carrying out channelizing (square frame 1014).Terminal was located in the different time interval (perhaps time slot), sent the complete CQI report (square frame 1016) for a plurality of FL carrier waves on the CQI channel.Terminal can circulate on a plurality of FL carrier waves, selects a FL carrier wave at every turn, and is used for sending the complete CQI report of the time interval transmission of complete CQI report for each selected FL carrier wave in appointment.
Terminal obtains the difference CQI report (square frame 1018) for a plurality of FL carrier waves of specified time interval.Terminal is carried out combined coding to the difference CQI report of a plurality of FL carrier waves, to obtain a code word (square frame 1020).Terminal can be selected block code based on the quantity of FL carrier wave, and can utilize selected block code to difference CQI report carrying out combined coding.Terminal can utilize the orthogonal code that is used for selected base station that code word is carried out channelizing (square frame 1022).Then, terminal sends code word (square frame 1024) on the CQI channel in specified time interval.
Figure 11 illustrates and is used for reducing for example embodiment of the processing 1100 of the pilot-frequency expense of multi-carrier operation.Terminal operation is in control-maintenance pattern, and it allows to carry out the transmission (square frame 1112) of gating pilot tone.Under control-maintenance pattern, terminal receives the data channel (for example, F-PDCH) (square frame 1114) that sends on the forward link.If there is not other transmission just to be sent out on reverse link, then terminal sends gating pilot tone (square frame 1116) on reverse link.If there is transmission just to be sent out on reverse link, then terminal sends full pilot tone (square frame 1118) on reverse link.For example, terminal can generate the affirmation for the grouping that receives on data channel, sends affirmation with full pilot tone on reverse link, and continues to send on reverse link the gating pilot tone after finishing the transmission of confirming.Terminal response is shifted out from the transfer of control-maintenance pattern in withdrawing from incident, and this withdraws from incident can be to the signaling that withdraws from control-maintenance pattern, the reception or the like (square frame 1120) of transfer of data on the reverse link.
