Description
Technical field
The present invention relates to synchronous CDMA (Code Division Multiple Access) 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 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) bring interference with two-forty carrying general business connecting system to system simultaneously, 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 is not because the business of some fixed rates of carrying and time delay needs NodeB that fast dispatch is carried out in the distribution and the distribution in transmission time of fixed physical resource.
(3). adopt HARQ (Hybrid Automatic Repeat Request mixes automatic repeat requests) technology.HARQ need make a start and send the feedback information ACK/NACK that a data grouping back wait reception is beamed back from receiving 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 the up shared data of carrying.
(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.
The base station needs feeding back ACK/NACK (reply/reply not) message to give a plurality of users in the existing HSUPA technology, and a plurality of users' ACK/NACK message reuse sends to the user on an E-HICH channel.According to the structure of BURST (burst) in the 3GPP standard, the time slot of an E-HICH is made of at interval data division, MIDAMBLE (training sequence) part and protection.

Prior art two: NodeB sends a plurality of users' ACK/NACK message reuse on an E-HICH channel.In process of transmitting, the orientation of different user may be different for NodeB, and E-HICH can aim at different user with crest by the multi-beam figuration, realize power control.But, if on an E-HICH, send a plurality of users' ACK/NACK is multiplexing, the crest of this channel be difficult to aim at a plurality of user sides to, and many more being difficult to more of number of users realize, therefore, be unsuitable for adopting the multi-beam figuration, and then power control just is difficult to realize, causes channel performance to worsen.
Summary of the invention

Embodiment
Core of the present invention provides the method and system that a kind of E-HICH goes up message reuse.During concrete enforcement, 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 sends, 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 handled and sent signal.
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
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 number at most 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 of 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.As seen from the figure, the time slot of E-HICH is made of at interval data symbol, training sequence and protection.Wherein, data symbol is divided into two parts, and mid portion is a training sequence.Protection is at interval in the end part.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 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 TPC/SS message of two E-PUCH channel correspondences, 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 of an E-PUCH channel of idle bit position carrying 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, does not need to 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 Factor, 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 as 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 is that the orthogonal code of 80bits expand for 1bitACK/NACK message with a length with user's length, and this message is long after the expansion is 80bits, sends to bit scramble unit 602, and this message is corresponding with a user.Message after the 602 pairs of orthogonal code expansions in 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, on the other hand the TPC/SS message of E-PUCH correspondence 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 sends.
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 determining the user according to arrival bearing or channel quality.
The base station can be controlled the ACK/NACK message of multiplexing which user on the E-HICH channel, and this process is to determine 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, this sign are notified the E-HICH numbering at the ACK/NACK message place that the user will receive.
Herein 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 to receive ACK/NACK message on which E-HICH by the relative numbering of indication E-HICH.The value of EI is determined by NodeB, like this, the base station can dispose one or more E-HICH channels and control the ACK/NACK message of multiplexing which user on each E-HICH channel, can also control the quantity of users multiplexing, thereby can carry out flexible configuration to E-HICH.
Certainly, in this step also can by with on the described 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 number at most 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 of 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 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, does not need to 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 sends on a kind of E-HICH channel.Fig. 8 shows the system block diagram that message sends 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.
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 by this sign.In native system be will be on the E-AGCH newly-increased EI be set at the numbering of the E-HICH that receives, also can by with on the described 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 as 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, with the E-HICH numbering of notifying the user to receive.Orthogonal code expanding element 601 will be that the orthogonal code of 80bits is expanded for 1bitACK/NACK message with a length 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 pairs of orthogonal code expansions in 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, on the other hand the TPC/SS message of E-PUCH correspondence 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.
Exemplify the preferred embodiment of an E-HICH channel signal sending method of the present invention below.
