Abstract

The invention relates to a time division-synchronous code division multiple access system, and discloses a method and equipment for receiving/sending a data packet in the time division-synchronous code division multiple access system. The method and the equipment effectively save system resource as well as reduce the signaling cost of an HS-SCCH simultaneously. In the method, for user terminals in an HS-SCCH Less state, if a data packet which is primarily transmitted by a base station node on a special resource pre-distributed by a certain user terminal fails to decode on the user terminal, the user terminal does not need the feedback of NACK; therefore, when no data packet is transmitted to the user terminal on the special resource, the base station node can schedule the special resource to other user terminals for using. In addition, the current HS-SCCH Less state of the user terminal can be modified according to conditions arranged by two parties of a physical layer command or the base station node and the user terminal.

Description

Data package dispatching method in the TDS-CDMA system and equipment

Technical field

The present invention relates to TDS-CDMA system, particularly the HS-SCCH Less in the TDS-CDMA system (High Speed Shared Control Channel Less saves high-speed shared control channel signaling) technology.

Background technology

Along with the continuous development of the communication technology and user raising day by day to quality of service requirement, the message transmission rate that reaches as high as 2Mbit/s that third generation partner program (3rd Generation Partnership Project, be called for short " 3GPP ") standard defined before Release 4 versions can not satisfy the user gradually to the demand of high-speed data service.In the case, 3GPP has introduced high speed downlink packet access (High Speed Downlink Packet Access is called for short " HSDPA ") technology in Release 5 standards.

HSDPA is a kind of enhanced scheme that 3GPP Release 5 proposes, main purpose is the high speed support to Packet data service, and obtain lower time delay, higher throughput of system and stronger service quality (Quality of Service, be called for short " QoS ") guarantee, can be referring to being 7 in the patent No., in 299,065 the United States Patent (USP), the method for the HSDPA business of in mobile communication system, transmitting that is proposed.From technical standpoint, HSDPA is by introducing high-speed downlink shared channel (HighSpeed Downlink Shared Channel, be called for short " HS-DSCH ") the enhancing air interface, and in universal mobile telecommunications system grounding wireless access network (UMTS Terrestrial Radio AccessNetwork is called for short " UTRAN "), strengthen corresponding functional entity.From bottom, mainly be to introduce mixed self-adapting repeat requests (Hybrid Automatic Repeat Request, be called for short " HARQ ") and adaptive modulation and coding (AdaptiVe Modulation and Coding, abbreviation " AMC ") technology increase data throughout.

The HARQ system is at automatic repeat requests (Automatic Repeat Request, abbreviation " ARQ ") introduces a forward error correction (Forward Error Correction in the system, be called for short " FEC ") subsystem, be used for correcting the error pattern of frequent appearance to reduce number of retransmissions, promptly in the error correcting capability scope, automatically correct a mistake, exceed the error correction scope and then require transmitting terminal to resend data, this has increased the reliability and the efficiency of transmission of system.That is to say that the channel condition that H-ARQ can adapt to moment automatically provides trickle data rate adjustment.The AMC technology makes system in the scope of restriction, can adjust modulation and coded system adaptively according to the change of channel quality.In an AMC system, those channel conditions that sit pretty are user (normally those users very near apart from the base station) preferably, can be endowed the modulation system of high-order and the coded system of two-forty (such as 16QAM and 1/2 Turbo encoding rate); And the relatively poor user's (normally those are in the user of cell boarder) of those channel conditions that are in unfavorable position then is endowed the modulation system of low order and the coded system of low rate (such as QPSK and 1/3 Turbo encoding rate).

The existing HS-DSCH link circuit self-adapting of TDS-CDMA system process as depicted in figs. 1 and 2.Mainly comprise two parts of base-station node (Node B) and user terminal (User Equipment is called for short " UE "), below these two parts be introduced respectively:

(1) process of Node B is as shown in Figure 1:

Step 100:Node B sends High-Speed Shared Control Channel (High Speed Shared ControlChannel, be called for short " HS-SCCH ") signaling, the Radio Resource position of the carrying HS-DSCH that notice UE distributes, modulation system, transmission block size and the information relevant etc. with HARQ.

Step 101:Node B sends HS-DSCH on the Radio Resource of HS-SCCH indication.

Step 102: high-speed shared information channel (the High Speed SharedInformation Ch8nnel that receives object UE, be called for short " HS-SICH "), status report (ACK/NACK and channel quality indicator (CQI) with the HS-SICH carrying, wherein ACK represents successfully to receive, NACK represents successfully not receive) send high level to, flow process finishes.

(2) process of UE is as shown in Figure 2:

Step 200:UE detects and receives one's own HS-SCCH signaling.

Step 201:UE receives corresponding high-speed physical downlink shared channel (HS-PDSCH) (High Speed-Physical Downlink Shared Channel is called for short " HS-PDSCH ") according to the indication of HS-SCCH, and HS-PDSCH is the physical channel of carrying HS-DSCH.

Step 202:UE is received HS-PDSCH, produces ACK/NACK information and is sending to Node B together with the CQI information that the nearest time obtains on corresponding HS-SICH, and flow process finishes.

HS-SCCH is the down control channel that TD-HSDPA (be TD-SCDMA HSDPA, the TDS-CDMA system high speed downlink packet inserts) uses, and is a physical channel, and it is used to carry all relevant bottom control information.HS-SCCH is shared by all UE that initiate the HSDPA business, but to single HS-DSCH Transmission Time Interval (Transmission Time Interval, be called for short " TTI "), each HS-SCCH can only take two spread spectrum code resources for a relevant downlink signaling of UE carrying HS-DSCH.

In various Packet data services, there is a class business, as packet voice (Voice over IP is called for short " VoIP "), its packet is less, and transmission is frequent and have certain periodicity, and is higher to delay requirement.And according to existing protocol, HS-DSCH transmission each time must just can be finished under the cooperation of HS-SCCH signaling.This is for big data packet traffic transmission, and HS-SCCH signaling resource requirement accounting is less; Yet the frequent and less business (such as VoIP) of packet for transmission, it is considerable that the expense of HS-SCCH signaling just seems, therefore be necessary existing system is optimized, reduce the HS-SCCH signaling consumption, can be referred to as to save high-speed shared control channel signaling HS-SCCHLess operation, this is operated pairing user terminal and then is in HS-SCCH Less state.

For adapting to the professional transmission of small data packets such as VoIP, have a kind of scheme to propose at present:

(1) distributes predefined HS-PDSCH resource for each user, and pre-allocation resource is this UE special use, packet is transmitted in first on the preallocated private resource and carries out, and do not follow the HS-SCCH signaling, UE carries out the blind check reception according to the configuration of high-level signaling to preallocated private resource, and (blind check is meant that UE does not know whether to have the data of issuing this UE on this preallocated private resource in advance, include but not limited to that following situation: UE does not know the size of data packet transmission piece in advance, do not know whether the transmission block on this resource issues oneself yet, but some kinds of transmission block sizes are detected, and detect characterizing the sign whether this packet belong to this UE in the packet according to the configuration of high level; Can refer to that also UE knows the size of data packet transmission piece, but do not know whether this transmission block issues oneself, but detect) characterizing the sign whether this packet belong to this UE in the packet that receives on the pre-allocation resource, if decode successfully then return ACK, the buffer memory of failing then receives data, returns NACK;

(2) when UE returns NACK, Node B can retransmit this packet by the mode of dynamic dispatching, uses HS-SCCH to dispatch during re-transmission;

(3) preallocated private resource can be made amendment by high-level signaling or physical layer command HS-SCCHOrder (order).

(4) HS-SCCH Less state is disposed by higher layer message.

The present inventor finds that in such scheme, the HS-PDSCH resource that is pre-assigned to certain UE is special-purpose, even Node B does not have transfer of data to give this UE on this resource, other UE also can't use this part resource.This be because, if Node B uses to other UE this part resource authorization by the HS-SCCH scheduling, then other UE will carry out the ACK/NACK feedback in the relevant position, and the current UE that carries out blind check on this part resource also can carry out the ACK/NACK feedback in the relevant position, cause conflict, so other UE can't use the untapped pre-allocation resource of above-mentioned UE, thereby cause the wasting of resources.In addition, HS-SCCH Less state is disposed by higher layer message, may cause the HS-SCCH Less state can not be timely according to current actual loading status update, cause UE in some cases (in longer a period of time, Node B does not have data packet transmission to give this UE being pre-assigned on the private resource of this UE) preallocated private resource is carried out long meaningless blind check, power wastage is serious.

Summary of the invention

The object of the present invention is to provide data package dispatching method and equipment in a kind of TDS-CDMA system, when reducing the HS-SCCH signaling consumption, conserve system resources more effectively.

For solving the problems of the technologies described above, embodiments of the present invention provide the data packet sending method in a kind of TDS-CDMA system, comprise following steps:

For the private resource of keeping for user terminal, described user terminal is in the high-speed shared control channel signaling HS-SCCH Less state of saving, if base-station node need send the first packet that passes to described user terminal on described private resource, then base-station node need not the signaling scheduling by HS-SCCH, directly on described private resource, send described packet, and, obtain the information whether described packet is correctly received according to the ACK signaling that the expression of whether receiving described user terminal feedback successfully receives;

If described base-station node does not have the first packet that passes to send to described user terminal on described private resource, then described private resource uses for described user terminal or other user terminals by the HS-SCCH signaling scheduling for described base-station node as required.

Embodiments of the present invention also provide the data packet receiving method in a kind of TDS-CDMA system, comprise following steps:

Be in the user terminal of HS-SCCH Less state, when blind check receives the packet of first biography on preallocated private resource, if the decoded packet data that receives is correct, then be shown as the ACK signaling that merit receives to the base-station node feedback form, incorrect if decode, then not to the not successful NACK signaling that receives of base-station node feedback expression.

Embodiments of the present invention also provide a kind of base-station node, comprise:

First judge module is used to judge whether current resource is the private resource of keeping for user terminal, and wherein, described user terminal is in the high-speed shared control channel signaling HS-SCCH Less state of saving;

Second judge module is used in the result of determination of described first judge module judging whether and need sending the first packet that passes to described user terminal on described private resource when being;

Sending module, be used in the result of determination of described second judge module when being, directly on described private resource, send described packet to described user terminal, and do not follow the HS-SCCH signaling, and, obtain the information whether described packet is correctly received according to the ACK signaling that the expression of whether receiving described user terminal feedback successfully receives;

Feedback module, be used for after described decoder module is correct to described decoded packet data, be shown as the ACK signaling that merit receives to the base-station node feedback form, after described decoder module is to described decoded packet data mistake, not to the not successful NACK signaling that receives of described base-station node feedback expression.

Embodiment of the present invention compared with prior art, the main distinction and effect thereof are:

For the user terminal that is in HS-SCCH Less state, if Node B carries out the failure of decoding of the first packet that passes in UE on the resource of preallocated this UE special use, then this UE does not need to carry out the feedback of NACK, thus Node B can be as required with keep for this UE special use but current untapped scheduling of resource uses for other UE.Because this UE is not when correctly receiving packet, do not need to Node B feedback NACK, therefore, do not send on the preallocated private resource of data at Node B to this UE, after this UE carries out the blind check reception, because therefore decoding error can or not clash with the current ACK/NACK that other UE fed back that takies this resource to Node B feedback NACK.That is to say that do not influencing systematic function, increasing on the basis of complexity, Node B can freely dispatch the private resource of having kept for UE as required, has broken the proprietary attribute of this resource, the wasting of resources is avoided in the flexibility that has improved scheduling of resource greatly.

In addition, can be according to the condition (not receiving packet in the duration in continuous presetting) of physical layer command or Node B and UE both sides' agreement as UE, revise the current HS-SCCH Less state of UE (include but not limited to revise preallocated private resource, data-modulated mode, need the transmission block number of blind check and size etc.), can remedy the deficiency of only using higher layer message configuration HS-SCCH Less state, make the HS-SCCH Less state variation of UE can respond the variation of actual loading situation fast, reduce the meaningless blind check of UE, reduce power consumption.

Embodiment

In the following description, in order to make the reader understand the application better many ins and outs have been proposed.But, persons of ordinary skill in the art may appreciate that even without these ins and outs with based on the many variations and the modification of following each execution mode, also can realize each claim of the application technical scheme required for protection.

For making the purpose, technical solutions and advantages of the present invention clearer, embodiments of the present invention are described in further detail below in conjunction with accompanying drawing.

In embodiments of the present invention, when Node B sends head biography packet to the UE that is in HS-SCCH Less state, do not follow the HS-SCCH signaling, directly on the private resource of reserving, send this packet.Packet in the embodiment of the present invention be data load less than preset thresholding and send frequent and have the small-sized packet of some cycles, as packet voice (Voice over IP, be called for short " VoIP ") packet, or based on PoC (the PTT over Cellular of Cellular Networks, be called for short " PoC ") packet, or be applied in packet in online game or the web page browsing etc.And, being the preallocated HS-PDSCH private resource of UE, can make amendment by high-level signaling or HS-SCCH Order order.UE passes the decoded packet data success to head and then returns ACK, if any signaling is not then fed back in the decoding failure.

When Node B does not receive the ACK that UE returns, can this packet be retransmitted by the mode of dynamic dispatching, use HS-SCCH to dispatch during re-transmission, and carry out normal ACK/NACK feedback, and can seize as required keep for other UE special uses but current untapped resource.

First execution mode of the present invention relates to the method that Node B sends packet, for convenience, supposes in the present embodiment, and Node B sends packet to UE A.

Specifically as shown in Figure 3, in step 300, Node B judges that whether the condition of the HS-SCCH Less state that changes UE A satisfies, if satisfy, forwards step 301 to; Otherwise forward step 302 to.Wherein, the change of HS-SCCH Less state includes but not limited to change preallocated private resource, changes the data-modulated mode, changes the transmission block number that needs blind check and size etc.; And the condition that changes the HS-SCCH Less state of UE A can be one of following or its combination in any: have the higher layer message indication to change the HS-SCCH Less state of UE A; The HS-SCCH Less state that the notifying changed UE A of physical layer command is arranged; The condition that Node B and UE A make an appointment when fixing on continuous the presetting of UE A approximately and do not receive packet in the duration as Node B and UE A both sides, changes the HS-SCCH Less state of UE A etc.

Because in the present embodiment, the change of HS-SCCH Less state is except can being disposed by higher layer message, can also pass through physical layer command (as HS-SCCH Order) changes, perhaps according to the condition changing of NodeB and UE A both sides agreement, therefore can remedy the deficiency of only using higher layer message configuration HS-SCCH Less state, make the HS-SCCH Less state variation of UE A can respond the variation of actual loading situation fast, reduce the meaningless blind check of UE A, reduce power consumption.

In step 301, Node B operates process ends accordingly according to new HS-SCCH Less state.Non-herein HS-SCCH Less state can be used as a kind of special case and is included in the HS-SCCHLess state, and promptly can regard as this moment does not have preallocated private resource.

In step 302, Node B judges that whether current resource is the preallocated private resource of HS-SCCH Less state to UE A, if forward step 303 to; Otherwise forward step 309 to.

In step 303, Node B judges whether to need to send HS-SCCH Order signaling, if forward step 304 to; Otherwise forward step 305 to.

In step 304, Node B carries out corresponding HS-SCCH Order transmission course, process ends.

In step 305, Node B judges whether to carry out the transmission first of packet, if forward step 306 to, otherwise forward step 309 to.

In step 306, Node B sends to UE A and does not follow the head of HS-SCCH signaling to pass packet.That is to say that Node B is directly first on the private resource of keeping for UE A to pass packet, and does not need the indication of HS-SCCH signaling.

In step 307, Node B judges whether to receive in the relevant position ACK of UE A feedback, if receive, then this transmission of data packets finishes; Otherwise, forward step 308 to.

In step 308, Node B puts into retransmission queue with this packet, process ends.

In step 309, Node B follows the transmission course of packet or the other guide of HS-SCCH, process ends as required to UE A or other UE.Such as, if Node B is after the head that sends to UE A passes the packet failure, in the process that retransmits this packet, enter into this step, then Node B in this step, give UEA by the HS-SCCH signaling with current untapped scheduling of resource, this resource both can be a resource of never keeping for any UE, also can be keep for other UE special uses but untapped resource (giving UE A) as the scheduling of resource that will keep for UE B special use, or the carrying out of keeping for UE A special use do not follow that the packet head of HS-SCCH passes but the untapped resource of UE A, follow the transmission course of the packet or the other guide of HS-SCCH signaling to UE A or other UE, Node B need receive the ACK/NACK from UE A or other UE feedback in this process, according to the ACK/NACK feedback of receiving, whether decision is further operated.

Because in the present embodiment, when not using for the preallocated private resource of certain UE, Node B this scheduling of resource can be given other UE use (as will keep for UE B special use but the untapped scheduling of resource of UE B uses for the UE A in the present embodiment, again such as will keep for UE A special use but the untapped scheduling of resource of UE A uses etc. for other UE), be that Node B can freely dispatch the private resource of having kept for certain UE as required, broken the proprietary attribute of this resource, improve the flexibility of scheduling of resource greatly, avoided the wasting of resources.

Second execution mode of the present invention relates to the method that UE receives packet, specifically as shown in Figure 4.

In step 400, UE judges that whether the condition of the HS-SCCH Less state that changes this UE satisfies, if satisfy, forwards step 401 to; Otherwise forward step 402 to.Wherein, the change of HS-SCCH Less state includes but not limited to change preallocated private resource, changes the data-modulated mode, changes the transmission block number that needs blind check and size etc.; And the condition that changes HS-SCCH Less state can be one of following or its combination in any: have the higher layer message indication to change HS-SCCH Less state; The notifying changed HS-SCCH Less of physical layer command state is arranged; The condition that Node B and this UE make an appointment when fixing on continuous the presetting of this UE approximately and do not receive packet in the duration as Node B and this UE both sides, changes HS-SCCH Less state etc.

Because in the present embodiment, the change of HS-SCCH Less state is except can being disposed by higher layer message, can also pass through physical layer command (as HS-SCCH Order) changes, perhaps according to the condition changing of NodeB and UE both sides agreement, therefore can remedy the deficiency of only using higher layer message configuration HS-SCCHLess state, make the HS-SCCH Less state variation of UE can respond the variation of actual loading situation fast, reduce the meaningless blind check of UE, reduce power consumption.

In step 401, UE operates process ends accordingly according to new HS-SCCH Less state.Non-HS-SCCH Less state can be included in the HS-SCCHLess state as a kind of special case herein.

In step 402, UE judges that whether current resource is the preallocated private resource of HS-SCCH Less state to this UE, if forward step 403 to; Otherwise forward step 410 to.

In step 403, UE judges whether to receive the HS-SCCH signaling, if do not receive, forwards step 404 to, otherwise forwards step 408 to.

In step 404, UE passes packet according to the head that in advance regulation blind check receives HS-SCCH Less state, forwards step 405 then to.Specifically because UE just can enter into this step under the situation of not receiving the HS-SCCH signaling, so UE can be directly on preallocated private resource blind check receive the packet of first biography.

In step 405, UE judges whether the decoded result of first biography packet is correct, if correct, forwards step 406 to; Otherwise, forward step 407 to.

In step 406, UE feeding back ACK, process ends.

In step 407, UE does not feed back NACK, process ends.

In step 408, UE judges whether the HS-SCCH signaling that receives is HS-SCCHOrder, if forward step 409 to; Otherwise, forward step 410 to.

In step 409, UE operates process ends accordingly according to HS-SCCH Order content.Changing HS-SCCH Less state by HS-SCCH Order is included in the step 400; This UE carries out corresponding operating according to the indication of HS-SCCH Order herein, be meant by HS-SCCHOrder transmission be other indications, as enter or withdraw from discontinuous reception or discontinuous emitting state etc., do not enumerate one by one at this.

In step 410, UE receives content corresponding according to the indication of HS-SCCH signaling, as packet or the other guide of reception by the HS-SCCH signaling scheduling, and feeding back ACK/NACK, process ends.Such as UE does not successfully receive the first packet that passes of Node B, and then this UE receives the packet of this UE according to the HS-SCCH signaling of Node B transmission on this Node B scheduled resources, and carries out normal ACK/NACK feedback.

Because in the present embodiment, if the head that receives on preallocated private resource passes the decoded packet data failure, then UE does not need to carry out the feedback of NACK.Therefore will keep for the private resource of this UE to dispatch at Node B under the situation of other UE, because this UE carries out the blind check reception and does not receive packet (the being decoding error) Shi Buhui that belongs to this UE feeding back NACK to Node B, therefore can not cause and conflict with the current ACK/NACK that UE fed back that takies this resource, avoided because Node B freely dispatches the private resource of having kept for certain UE, and the mistake that causes is unusual.

Need to prove that method execution mode of the present invention can be realized in software, hardware, firmware or the like mode.No matter the present invention be with software, hardware, or the firmware mode realize, instruction code can be stored in the memory of computer-accessible of any kind (for example permanent or revisable, volatibility or non-volatile, solid-state or non-solid-state, medium fixing or that change or the like).Equally, memory can for example be programmable logic array (Programmable Array Logic, be called for short " PAL "), random access memory (Random Access Memory, be called for short " RAM "), programmable read only memory (Programmable Read Only Memory, be called for short " PROM "), read-only memory (Read-Only Memory, be called for short " ROM "), Electrically Erasable Read Only Memory (Electrically Erasable Programmable ROM, be called for short " EEPROM "), disk, CD, digital versatile disc (Digital Versatile Disc is called for short " DVD ") or the like.
