Description
Technical field
The present invention relates to synchronous CDMA of time-division (Time Division-Synchronous CodeDivision Multiple Access; TD-SCDMA) high speed uplink packet in inserts (High SpeedUplink Packet Access; HSUPA) technical field, message reuse, sending method and system on particularly a kind of E-HICH.
Background technology
High speed uplink packet inserts (High Speed Uplink Packet Access; HSUPA) be the technology of developing for the high-speed transfer of carrying out upstream data on the 3G (Third Generation) Moblie technical foundation; It can provide the complete desired multimedia of IMT2000, video flowing and other internet protocol-based (InternetProtocol, business IP).
HSUPA among the TD-SCDMA has adopted some new technology to realize these professional supports.These new technology comprise:
(1). adopt Uplink Shared Channel to improve resource utilization.
(2). adopt several kinds of scheduling, by base station assigns physical resource and power based on NodeB (base station).
HSUPA supports scheduled transmission and non-scheduled transmission.Scheduled transmission is for fear of because too much UE (User Qquipment; Subscriber equipment; Be called for short the user) carry the general business connecting system and bring interference with two-forty simultaneously to system; NodeB carries out the rapidity scheduling to the distribution and the distribution in transmission time of fixed physical resource, with consistent as far as possible uplink interference.Non-scheduled transmission does not need NodeB that fast dispatch is carried out in the distribution and the distribution in transmission time of fixed physical resource owing to carry the business of some fixed rates and time delay.
(3). adopt HARQ (Hybrid Automatic Repeat Request mixes automatic repeat requests) technology.HARQ need make a start and after data of transmission are divided into groups, wait for the feedback information ACK/NACK that reception is beamed back from the receipts end, and making a start determines whether to carry out the repeating transmission of data block according to feedback message.
HSUPA has also increased some new channels newly to support above-mentioned business.These channels comprise:
(1) .E-PUCH (uplink physical channel of enhancing) is mainly used in and carries up shared data.
(2) .E-HICH (E-DCH, HARQ confirms indicating channel) is mainly used in loading ACK/NACK message.
(3) .E-AGCH (E-DCH (enhancing dedicated channel) absolute acknowledgement channel) is mainly used in bearing resource, power configuration, E-PUCH synchronously and message such as power control.
Wherein, the TPC/SS of E-AGCH channel bearing E-PUCH (transmitting power control/simultaneous bias) message.

Embodiment
Core of the present invention provides the method and system that a kind of E-HICH goes up message reuse.During practical implementation, with the TPC of E-PUCH in the non-scheduled transmission and SS message reuse on the idle bit position of E-HICH channel.The present invention also provides a kind of E-HICH to go up the method and system that message is sent; ACK/NACK arrival bearing is identical or the user that signal quality is close is multiplexing on the E-HICH channel, and the method and system of the last message reuse of application E-HICH are carried out processing and transmitting to signal.
In order to make those skilled in the art person understand the present invention program better, the present invention is done further detailed description below in conjunction with accompanying drawing and execution mode.
Below introduce the method and system that E-HICH goes up message reuse.
Fig. 1 shows the flow process that E-HICH of the present invention goes up message reuse.Fig. 2 also shows the principle of this message reuse.
Step 101: user's (ACK/NACK) message of replying is expanded by orthogonal code.
The length of a user's ACK/NACK message is 1bit, is expanded by orthogonal code.The number of orthogonal code is 80, needs multiplexing user's most number also be 80, and like this, orthogonal code is just only corresponding with a user.Be that 80bits is long after each ACK/NACK message is expanded by orthogonal code, and corresponding with a user.
Step 102: the message after will expanding is through bit scramble.
The bit scramble process can adopt the R99 bit scramble.
Step 103: the message after the scrambling is modulated.
Modulation system is QPSK (Quarternary Phase Shift Keying, a quaternary phase shift keying).
Step 104: the message to modulating is carried out power adjustments.
Power adjustment procedure adopts user's certain gain and signal multiplication mode to carry out.
Step 105: subscriber signal is multiplexing on the E-HICH channel.
The multichannel subscriber signal all passes through above-mentioned orthogonal code expansion, and the QPSK modulation is after these processes of bit scramble and power adjustments, multiplexing on the E-HICH channel.
Be 88bits because but each E-HICH channel bearer messages is long, and be 80bits through the subscriber signal length that abovementioned steps is handled, like this, this channel has the idle data position of 8bits.
Fig. 3 shows the structure of time slot figure of E-HICH.Can know that by figure the time slot of E-HICH is made up of data symbol, training sequence and protection at interval.Wherein, data symbol is divided into two parts, and mid portion is a training sequence.Protection is the part at the end at interval.Each data symbol part all has idle bit.
Step 106: the TPC/SS message in the non-data dispatching is filled on the idle bit position of E-HICH channel.
The TPC of E-PUCH in the non-scheduled transmission and SS message at first will be passed through QPSK modulation and power adjustments.
Fig. 4 shows modulation and the power adjustments flow process of TPC/SS.
Step 401: TPC/SS message is modulated.
TPC/SS message is carried out the QPSK modulation.
Here, have the corresponding TPC/SS message of two E-PUCH channels, be labeled as TPC1/SS1 and TPC2/SS2 respectively.
Step 402: the message after the modulation is carried out power adjustments.
Power adjustment procedure adopts code channel certain gain and signal multiplication mode to carry out.
As shown in Figure 5, TPC1/SS1 message after the processing and TPC2/SS2 message are filled into the idle bit position of two data symbolic components.The TPC1/SS1 message that an E-PUCH channel is carried in the idle bit position of first data symbol part, the TPC2/SS2 message that another E-PUCH is carried in the idle bit position of second data symbol part.
Also having a kind of situation, is that system does not have the E-PUCH in the non-scheduled transmission, need not transmit TPC and SS message so, and like this, any bit is just filled in corresponding idle bit position.
Step 107: message sends behind spread spectrum.
The spread spectrum process can be 16 channel code spread spectrum by SF (Spreading Fac tor, spreading factor).
Like this, just TPC and the SS message reuse with E-PUCH transmits on the idle bit position of E-HICH, realized in the non-scheduled transmission E-PUCH channel power control and synchronous.
The present invention also provides the system of message reuse on a kind of E-HICH channel.Fig. 6 shows the system block diagram of message reuse on this E-HICH channel.
This system comprises with lower unit: message conversion unit 61; Message reuse unit 62 links to each other with 61; Message filler cells 63 links to each other with 62; Spectrum-spreading unit 64 links to each other with 63.
Spectrum-spreading unit 64 is used for that the message of E-HICH channel is carried out spread spectrum and sends.
Wherein, message conversion unit 61 comprises: orthogonal code expanding element 601; Bit scramble unit 602 links to each other with 601; Modulating unit 603 links to each other with 602; Power adjustments unit 604 links to each other with 603.
Orthogonal code expanding element 601 is used for user message is expanded with orthogonal code.The number of orthogonal code is 80, and the E-HICH channel needs multiplexing user's number maximum also be 80, and like this, orthogonal code is just only corresponding with a user.Be the message of 1bit like a length, it is long to expand to 80bits by orthogonal code, and corresponding with a user.
The message reuse system describes similar to message reuse method on Signal Processing process and the E-HICH channel on this E-HICH channel.Orthogonal code expanding element 601 uses a length with user's length for bbitACK/NACK message and expands as the orthogonal code of 80bits, and this message length is 80bits after the expansion, sends to bit scramble unit 602, and this message is corresponding with a user.Message after the 602 pair of orthogonal sign indicating numbers expansion of bit scramble unit carries out sending to modulating unit 603 behind the R99 bit scramble.Modulating unit 603 carries out the QPSK modulation with the message behind bit scramble on the one hand, and on the other hand that E-PUCH is corresponding TPC/SS message is carried out the QPSK modulation, and the message after these two kinds of modulation is sent to power adjustments unit 604.Power adjustments unit 604 multiplies each other user's ACK/NACK message and user's certain gain on the one hand, sends to message reuse unit 62; On the other hand TPC/SS message and code channel certain gain are multiplied each other, send to message filler cells 63.Message reuse unit 62 is multiplexing on an E-HICH channel with multichannel user's ack/nack signal, re-sends to message filler cells 63; Message filler cells 63 is filled into the TPC/SS message of receiving on the idle bit position of the E-HICH channel of receiving, and sends to spectrum-spreading unit 64, and wherein two parts are divided in the idle bit position, in the symbol data part of E-HICH time slot; Spectrum-spreading unit 64 carries out spread spectrum with the message of E-HICH channel and sends.
Before above-mentioned E-HICH message reuse method, can also add some steps, to realize the multi-beam figuration.
Below introduce E-HICH of the present invention and go up the method and system that message is sent.
Fig. 7 shows the flow process of the message method of having used E-HICH message reuse method.
Step 701: the ACK/NACK message of confirming the user according to arrival bearing or channel quality.
The base station can be controlled multiplexing which user's on the E-HICH channel ACK/NACK message, and this process is to confirm according to user's arrival bearing or channel quality.The ACK/NACK message reuse of user's correspondence that NodeB is identical with arrival bearing as much as possible or channel quality is close is on an E-HICH.But when can not guaranteeing that user's arrival bearing is identical, when needing to obtain certain figuration gain, the last multiplexing user's of E-HICH number just can not be too many.
Step 702: newly-increased sign on the E-AGCH channel, the E-HICH numbering that the ACK/NACK message that this sign notifies the user to receive belongs to.
Here be designated EI message, EI also can be a field on a certain message.At first each user is set up an E-HICH channel set, in this set, each E-HICH channel all has a relative numbering as sign.User's ACK/NACK message can be multiplexed on a certain E-HICH channel of this set.The last newly-built EI message of E-AGCH notifies the user on which E-HICH, to receive ACK/NACK message through the relative numbering of indication E-HICH.The value of EI is confirmed by NodeB; Like this; The base station can dispose one or more E-HICH channels and control multiplexing which user's on each E-HICH channel ACK/NACK message, can also control the quantity of users multiplexing, thereby can carry out flexible configuration to E-HICH.
Certainly, in this step also can through with on the said E-AGCH channel or other message sets on other channel be that the pairing E-HICH of identifying user numbering is to reach same purpose.
Step 703: user's ACK/NACK message is expanded by orthogonal code.
The length of a user's ACK/NACK message is 1bit, is expanded by orthogonal code.The number of orthogonal code is 80, needs multiplexing user's most number also be 80, and like this, orthogonal code is just only corresponding with a user.Be that 80bits is long after each ACK/NACK message is expanded by orthogonal code, and corresponding with a user.
Step 704: the message after will expanding is through bit scramble.
The bit scramble process adopts the R99 bit scramble.
Step 705: the message after the scrambling is modulated.
Modulation system is QPSK.
Step 706: the message to modulating is carried out power adjustments.
Power adjustment procedure adopts user's certain gain and signal multiplication mode to carry out.
Step 707: subscriber signal is multiplexing on the E-HICH channel.
The multichannel subscriber signal all passes through above-mentioned orthogonal code expansion, and the QPSK modulation is after these processes of bit scramble and power adjustments, multiplexing on an E-HICH channel.
Be 88bits because but each E-HICH channel bearer messages is long, and be 80bits through the subscriber signal length that abovementioned steps is handled, like this, this channel has the idle data position of 8bits.
Step 708: the TPC/SS message in the non-data dispatching is filled on the idle bit position of E-HICH channel.
The TPC of E-PUCH in the non-scheduled transmission and SS message at first will be passed through QPSK modulation and power adjustments.
Also having a kind of situation, is that system does not have the E-PUCH in the non-scheduled transmission, need not transmit TPC and SS message so, and like this, any bit is just filled in corresponding idle bit position.
Step 709: message sends behind spread spectrum.
The spread spectrum process can be 16 channel code spread spectrum by SF (Spreading Factor, spreading factor).Send mode adopts the multi-beam figuration.
The present invention also provides the system that message is sent on a kind of E-HICH channel.Fig. 8 shows the system block diagram that message is sent on this E-HICH channel.
This system comprises with lower unit: user selection unit 801; Sign setup unit 802 links to each other with 801; Message conversion unit 61 links to each other with 801; Message reuse unit 62 links to each other with 61; Message filler cells 63 links to each other with 62; Spectrum-spreading unit 64 links to each other with 63.
User selection unit 801 is used to select the user that arrival bearing is identical or channel quality is close, and the E-HICH numbering that will carry these user messages sends to sign setup unit 802.
Sign setup unit 802 is used for a newly-increased sign is set at the numbering of the pairing E-HICH of user that is selected by user selection unit, and the E-HICH channel of notifying the user to receive through this sign.Be the numbering that EI newly-increased on the E-AGCH is set at the E-HICH that receives in native system, also can through with on the said E-AGCH channel or other message sets on other channel be that the pairing E-HICH numbering of identifying user is to reach same purpose.
Spectrum-spreading unit 64 is used for that the message of E-HICH channel is carried out spread spectrum and sends.
Wherein, message conversion unit 61 comprises: orthogonal code expanding element 601; Bit scramble unit 602 links to each other with 601; Modulating unit 603 links to each other with 602; Power adjustments unit 604 links to each other with 603.
Orthogonal code expanding element 601 is used for user message is expanded with orthogonal code.The number of orthogonal code is 80, and the E-HICH channel needs multiplexing user's number maximum also be 80, and like this, orthogonal code is just only corresponding with a user.Be the message of 1bit like a length, it is long to expand to 80bits by orthogonal code, and corresponding with a user.
Message transmission system is described similar to message method on Signal Processing process and the E-HICH channel on this E-HICH channel.Selected identical user or the close users of channel quality of arrival bearing of user selection unit 801, and the E-HICH numbering that will carry these user messages sends to and identifies setup unit 802.Sign setup unit 802 is gone up newly-increased EI with E-AGCH and is set at the numbering of the E-HICH that receives, and sends to the user, numbers to notify the user E-HICH that institute will receive.Orthogonal code expanding element 601 will use one to grow and expand as the orthogonal code of 80bits for 1bitACK/NACK message by the selected user's of user selection unit 801 length; This message length is 80bits after the expansion; Send to bit scramble unit 602, this message is corresponding with a user.Message after the 602 pair of orthogonal sign indicating numbers expansion of bit scramble unit carries out sending to modulating unit 603 behind the R99 bit scramble.Modulating unit 603 carries out the QPSK modulation with the message behind bit scramble on the one hand, and on the other hand that E-PUCH is corresponding TPC/SS message is carried out the QPSK modulation, and the message after these two kinds of modulation is sent to power adjustments unit 604.Power adjustments unit 604 multiplies each other user's ACK/NACK message and user's certain gain on the one hand, sends to message reuse unit 62; On the other hand TPC/SS message and code channel certain gain are multiplied each other, send to message filler cells 63.Message reuse unit 62 is multiplexing on an E-HICH channel with multichannel user's ack/nack signal, re-sends to message filler cells 63; Message filler cells 63 is filled into the TPC/SS message of receiving on the idle bit position of the E-HICH channel of receiving, and sends to spectrum-spreading unit 64, and wherein two parts are divided in the idle bit position, in the symbol data part of E-HICH time slot; Spectrum-spreading unit 64 carries out spread spectrum with the message of E-HICH channel and sends.

User 1 adopts non-scheduled transmission mode to send data, and user 2 adopts scheduling modes to send data, and user 2 arrival bearing and user 1 identical or user's 2 channel quality and user's 1 is close.Newly-increased sign is an EI message here on the E-AGCH1 channel, and EI also can be a field on a certain message certainly.It is E-HICHI that this EI message is notified 1 channel that will receive of user through the transmission of E-AGCH1.Because user 1 adopts non-scheduling mode, so the idle bit position of last first data symbol part of E-HICH1 is used for carrying the TPC1/SS1 message of the E-PUCH1 channel of user's 1 correspondence.Newly-increased EI message on the E-AGCH2 channel, notifying 2 channels that will receive of user through the transmission of E-AGCH2 is E-HICH1.User 1 after E-HICH 1 load multiplexing and user 2 ACK/NACK message.Because user 2 adopts scheduling mode, so fill with any bit on the idle bit position of second data symbol of E-HICH1 part.Afterwards, E-HICH1 sends through adopting the multi-beam figuration behind the spread spectrum.
Visible by above embodiment, owing to the TPC1/SS1 message that the E-PUCH1 channel is carried in E-HICH1 first data symbol idle bit position partly, therefore realized in the non-scheduled transmission E-PUCH1 channel power control and synchronous.Simultaneously, owing to carried user 1 and user's 2 ACK/NACK message on the E-HICH1, and these two users' arrival bearing is identical or channel quality is close, therefore can realize the multi-beam figuration, and then realize power control having promoted channel performance.
Though described the present invention through embodiment, those of ordinary skills know, the present invention has many distortion and variation and do not break away from spirit of the present invention, hope that appended claim comprises these distortion and variation and do not break away from spirit of the present invention.
