Description

Dispatching information transmission method and user terminal and base-station node

Technical field

The present invention relates to moving communicating field, particularly high speed uplink packet inserts (High SpeedUplink Packet Access is called for short " HSUPA ") technology.

Background technology

Universal mobile telecommunications system (Universal Mobile Telecommunication System is called for short " UMTS ") is one of global main at present 3G (Third Generation) Moblie (The Third Generation is called for short " 3G ") system.The UMTS system is made up of three parts, and promptly core net (Core Network is called for short " CN "), universal mobile telecommunications system grounding wireless access network (UMTS Terrestrial RadioAccess Network is called for short " UTRAN ") and user terminal are formed.The interface definition of CN and UTRAN is the Iu interface, and the interface definition of UTRAN and user terminal is the Uu interface.

UMTS protocol version the earliest is R99, and in this version, the carrying of uplink and downlink business all is based on dedicated channel (Dedicated Channel is called for short " DCH "), and the message transmission rate that can reach is 384Kbps.But along with the user is more and more higher to the demand of transmitting high speed data, the protocol specification of having released R4, R5, R6 three phases is subsequently successively organized in the UMTS standard formulation, introduced high speed downlink packet access (High Speed Downlink Packet Access, be called for short " HSDPA ") technology and high speed uplink packet access (High Speed Uplink Packet Access, be called for short " HSUPA ") technology, peak rate up to 14.4Mbps and 5.76Mbps can be provided respectively, simultaneously, also improved spectrum efficiency greatly.

Wherein, HSUPA is called dedicated channel (the Enhanced-Dedicated channel of enhancing again, be called for short " E-DCH "), the main feature of HSUPA comprises in the R6 version: adopt short frame of 2ms or 10ms frame, adopt mixed self-adapting repeat requests (Hybrid Automatic RepeatRequest in physical layer, be called for short " HARQ "), up base station fast dispatch technology etc.In order to realize the high-efficiency transfer of user uplink data, HSUPA has increased two uplink physical channels and three down physical channels newly, they are respectively E-DCH Dedicated Physical Data Channel (the E-DCH DedicatedPhysical Data Channel that is used to transmit data, be called for short " E-DPDCH "), be used to transmit E-DCH Dedicated Physical Control Channel (the E-DCH Dedicated Physical Control Channel of accompanied by physical layer signaling, be called for short " E-DPCCH "), be used to control E-DCH absolute grant channel (the E-DCH Absolute Grant Channel of user's uplink speed, be called for short " E-AGCH ") and E-DCH relative authorization channel (E-DCH Relative Grant Channel, be called for short " E-RGCH "), and be used for the E-DCH HARQ indicating channel (E-DCH HARQ Indicator Channel, abbreviation " E-HICH ") of carrying from ACK (affirmations)/NACK (the not confirming) information of base-station node (Node B).Except physical layer increases channel,, in media interviews control (Medium Access Control is called for short " MAC "), introduce MAC-e (e refers to strengthen) and two sublayers of MAC-es again, to support HARQ and fast dispatch in order to cooperate HSUPA.MAC-e and MAC-es are between physical layer and the MAC-d (d refers to special use).

Specifically, go up the agreement relevant at wireless air interface (Uu interface) and relate generally to physical layer, MAC layer and corresponding radio resource key-course (Radio Resource Controller is called for short " RRC ") layer with E-DCH.Wherein, the MAC layer of E-DCH comprises MAC-e, MAC-es and three media access control sublayer of MAC-d again.In the UTRAN side, the MAC-e entity is in base-station node, and the MAC-es entity is at service wireless network controller (Serving Radio Network Controller, be called for short " SRNC ") in, and, do not distinguish MAC-e and MAC-es in subscriber terminal side, they are present in the same functional unit.

The MAC layer structure of subscriber terminal side E-DCH as shown in Figure 1, transmitting terminal at E-DCH is a subscriber terminal side, from Radio Link control (Radio Link Control, abbreviation " RLC ") logic channel Dedicated Traffic Channel (the Dedicated Traffic Channel of layer, be called for short " DTCH ") and Dedicated Control Channel (Dedicated Control Channel, abbreviation " DCCH ") at first enters MAC-d and form MAC-d protocol Data Unit (Protocol Data Unit, be called for short " PDU "), the MAC-d PDU of same logic channel forms MAC-es PDU through MAC-es again, MAC-es PDU further forms MAC-e PDU again in MAC-e, after the E-DCH transmission channel is mapped to physical layer.

The MAC layer structure of UTRAN side E-DCH as shown in Figure 2, receiving terminal at E-DCH, it is the UTRAN side, from the MAC-e PDU of E-DCH transmission channel at first the MAC-e demultiplexing in being present in base-station node handle and form MAC-es PDU, be transferred to afterwards among the SRNC by after the processing such as MAC-es carries out that at first grand diversity is selected, reordered, decomposite each MAC-d PDU again and deliver to the MAC-d unit, after logic channel DTCH and DCCH deliver to rlc layer.

MAC-e PDU comprises head and payload part, its structure as shown in Figure 3, the payload part of MAC-e PDU comprises a plurality of multiplexing MAC-es PDU that together form, the length that optionally is used for up fast packet scheduling is schedule information (the Scheduling Information of 18 bits, be called for short " SI "), and be used to make the length of MAC-e PDU to equal the possible filling field of the E-DCH transport block length of appointment; The head of MAC-e PDU then is made of each MAC-es PDU relevant parameters DDI field and N field, and the length of these two fields is 6 bits, and in addition, the head of MAC-e PDU also comprises optional DDIO field.

Protocol specification TS25.321 according to 3GPP, the form of MAC-e PDU is counted D and is had following four kinds of structures with whether transmitting SI and remaining bits, wherein, SI is that E-DCH carries out the metrical information that up fast packet scheduling relied on based on base-station node, and E-DCH supports to trigger and two kinds of SI report manners of Event triggered based on the cycle at present; Remaining bits is counted D deducts the contained n of a MAC-ePDU MAC-es PDU and corresponding n DDI that comprises and N field in MAC-e PDU head for the E-DCH transport block length the remaining bit number of length.

(a) transmit the MAC-e PDU of SI separately, this MAC-e PDU is made of the SI of this 18 bit long;

(b) when remaining bits is counted D less than 18 bits, then do not transmit SI and remaining bits is a filling bit;

(c) count D when remaining bits and be equal to or greater than 18 bits, but during less than 24 bits, then with SI directly level be associated in the last of MAC-es PDU, remaining bit is filling bit (a 0-5 bit);

(d) when remaining bits is counted D and is equal to or greater than 24 bits, then the SI level is associated in the last of MAC-es PDU, and is DDIO=" 111111 " at the last additional special DDI of MAC-e PDU head, remaining bit is a filling bit.

MAC-e PDU transmits on E-DPDCH, and relevant control signaling is transmitted on E-DPCCH.The information of the last transmission of E-DPCCH comprises: retransmission sequence number (Retransmission Sequence Number, abbreviation " RSN "), E-DCH transformat combination indication (E-DCH Transport FormatCombination Indicator, be called for short " E-TFCI ") and " Happy (satisfaction) " bit, they take 2 bits, 7 bits and 1 bit respectively.Wherein, RSN is mainly used in the new data indication of HARQ process and the redundancy versions indication that retransmits, and " Happy " bit is mainly used in the assist control to ascending grouping scheduling, and the E-TFCI span is 0-127, be used to indicate the size of MAC-e PDU, i.e. E-DCH transmission block size.Standard TS25.321 according to 3GPP, the Transmission Time Interval of 2ms (Transmission Time Interval, being called for short " TTI ") MAC-ePDU of pattern and 10ms TTI pattern all can dispose in two big small sets of E-DCH transmission block, Fig. 4 and Fig. 5 have provided two E-DCH transmission block sizes of 2ms TTI pattern collection respectively, and Fig. 6 and Fig. 7 have provided two E-DCH transmission block size collection of 10msTTI pattern respectively.Wherein, the indicated E-DCH transmission block size of E-TFCI=0 is that the transmission block of 18 bits is mainly used in the up SI of independent transmission.

At present, there is dual mode on E-DPDCH, to transmit SI, a kind of is the mode of being transmitted SI by MAC-e PDU separately, whole M AC-e PDU promptly is made of the SI of this 18 bit long in this case, another kind be SI with data transmission manner in MAC-e PDU, SI places that each MAC-es PDU's is last in this case.

Because E-DPDCH adopts the HARQ operation, so the HARQ operation is also supported in the transmission of SI.According to the TS25.321 of current version, to the situation that SI transmits separately, maximum the number of transmissions is 8 times that fix; The situation that SI is transmitted in MAC-e PDU with data, maximum number of retransmissions is by the HARQ configuration parameter decision of the stream of the E-DCH MAC-d in the data division that transmits simultaneously with SI among this MAC-e PDU, this parameter is by the information unit of RRC (Information Element, abbreviation " IE ") " E-DCH MAC-d flow maximum number of retransmission (E-DCH MAC-d flows maximum retransmission) " provides, and its span is 0-15 time.

Because the method for synchronization has been adopted in the operation of the HARQ among the E-DCH, the initial transmission and the re-transmission that are certain HARQ process always occur in the fixing moment, therefore for 2ms TTI pattern, always have 8 parallel HARQ processes, for 10ms TTI pattern, always have 4 parallel HARQ processes.Therefore, the once re-transmission time of the HARQ process among the E-DCH (is that user terminal sends a MAC-e PDU from certain TTI, do not receive response message NACK to what user terminal received that base-station node sends, and set time of data retransmission thus), for 2ms TTI pattern, be that 8 * 2ms is 16ms; For 10ms TTI pattern, be that 4 * 10ms is 40ms.

In actual applications, there is following problem in such scheme: base-station node possibly can't obtain up-to-date SI report, thereby has influenced the performance of E-DCH ascending grouping scheduling.

Cause the main cause of this situation to be, under the dual mode of transmission SI on the E-DPDCH, for 2ms TTI, if transmit SI separately, then 8 transmission of maximum demand, that is to say the longest need be 128ms through 8 * 16ms, if SI transmits in MAC-e PDU with data, then maximum possible needs 15 re-transmissions, that is to say that the longest need be 256ms through 16 * 16ms; For 10ms TTI, if transmit SI separately, then 8 transmission of maximum demand, that is to say that the longest need be 320ms through 8 * 40ms, if SI transmits in MAC-e PDU with data, then maximum possible needs 15 re-transmissions, that is to say that the longest need be 640ms through 16 * 40ms.

But, because when the incident that takes place to stipulate in the SI report triggering mechanism when user terminal, the remaining bits that reaches the MAC-e PDU of cycle of stipulating in the SI report triggering mechanism or certain TTI were counted D and be equal to or greater than 18, user terminal all needs to send new SI to base-station node to be reported.And, because the SI transmission has very high priority, even be on the HARQ process of special value " Zero_Grant " at service authorization parameter and be on the HARQ process of non-active state and all allow transmission SI, therefore, be not difficult to find, during the HARQ of certain SI report retransmitted, user terminal probably sent new SI to base-station node.

As shown in Figure 8, because except that the HARQ process that old SI report retransmits, other HARQ process all may be transmitted new SI report, and before this old SI report re-transmission is finished, if new SI report has successfully been received by base-station node, so, after this old SI report completes successfully transmission, will override this new SI report, thereby what cause that base-station node obtains is not up-to-date SI report, has reduced the performance of ascending grouping scheduling largely.

Summary of the invention

In view of this, main purpose of the present invention is to provide a kind of dispatching information transmission method and user terminal and base-station node, makes base-station node can obtain up-to-date SI report, thereby guarantees the performance of E-DCH ascending grouping scheduling.

When described the 2nd PDU retransmits, be set to values different when just passing with the corresponding E-TFCI field of the 2nd PDU in the E-DPCCH control information; Perhaps,

When described the 2nd PDU retransmits, be set to the value of representing that schedule information is invalid with the 2nd PDU corresponding " Happy " bit in the E-DPCCH control information, when wherein retransmitting in the E-DPCCH control information " Happy " bit be redefined into the indication schedule information whether effective.

In this external described method, also comprise following steps:

When described base-station node successfully receives the 3rd PDU that comprises schedule information on the HARQ process, judge in the scheduled duration before this and whether successfully received the 4th PDU that comprises schedule information on other HARQ process, if, the number of transmissions that then compares the 3rd PDU and the 4th PDU, if the number of transmissions of the 3rd PDU is greater than the number of transmissions of the 4th PDU, it is invalid then the schedule information among the 3rd PDU to be judged to be, otherwise the schedule information among the 3rd PDU is judged to be effectively;

Described scheduled duration is that described user terminal is from sending PDU to receiving the time span of described base-station node to the feedback information of this PDU.

In this external described method, also comprise following steps:

If the schedule information that described base-station node is instructed to wherein when receiving PDU is invalid, or judge that the schedule information among the received PDU is invalid, then abandon the schedule information among this PDU.

The present invention also provides a kind of user terminal, comprise the HARQ entity, at least two HARQ processes are wherein arranged, also comprise judge module, when the Radio Link collection RLS that is used for comprising the involved Serving cell of the first protocol Data Unit PDU of schedule information on arbitrary HARQ process of described HARQ entity successfully receives, comprise schedule information among the 2nd PDU that judges whether transmitting on other HARQ process, and the transmitting time first of the 2nd PDU is early than the transmitting time first of a described PDU, if the schedule information that is comprised among then discarded described the 2nd PDU.

Wherein, during the schedule information that in discarded described the 2nd PDU, comprised, described judge module is further differentiated the content of carrying among described the 2nd PDU, if comprise schedule information and high level data among the 2nd PDU simultaneously, then be provided with among the E-DPCCH and the corresponding control information of the 2nd PDU, the schedule information among indication base-station node the 2nd PDU is invalid; Do not comprise high level data if comprise schedule information among the 2nd PDU, then indicate described HARQ entity to stop the re-transmission of the 2nd PDU.

Embodiment

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

Core of the present invention is, user terminal writes down the transmitting time first of the PDU on each HARQ process, when the PDU who comprises SI on arbitrary HARQ process sends successfully, if comprise SI among the 2nd PDU that is transmitting on other HARQ process, and the transmitting time first of the 2nd PDU is early than the transmitting time first of a PDU, user terminal is invalid by the SI among indication base-station node the 2nd PDU, or stops the re-transmission of the 2nd PDU, discards the SI that is comprised among the 2nd PDU.Base-station node is when successfully receiving the 3rd PDU that comprises SI, judge the 4th PDU that comprises SI that whether has successfully received in the scheduled duration before this on other HARQ process, if, the number of transmissions by the 3rd PDU relatively and the 4th PDU then, judge whether the SI among current successful the 3rd PDU that receives is up-to-date SI, if not, it is invalid then the SI among the 3rd PDU of current success reception to be judged to be, and base-station node will be instructed to invalid or be judged as invalid SI abandon.Wherein, scheduled duration is that user terminal is from sending PDU to the time span that receives the feedback information of this PDU from base-station node.

More than principle of the present invention has been carried out simple declaration, be described in detail according to the transmission method of this principle below SI among the first execution mode E-DCH of the present invention.

As shown in Figure 9, in step 901, user terminal writes down the transmitting time first of PDU on each HARQ process.Specifically, user terminal writes down the transmitting time first of PDU on each HARQ process by preserving the Connection Frame Number and the subframe numbers of PDU when sending first on each HARQ process.Such as, the incident that is taking place to stipulate in the SI trigger mechanism when user terminal, the remaining bits that reaches cycle of stipulating in the SI trigger mechanism, the MAC-e PDU by a TTI transmission are counted D more than or equal to 18 or owing to other reason need send when comprising the MAC-e PDU of SI on certain HARQ process, by preserving Connection Frame Number and the subframe numbers of this MAC-e PDU when sending first on this HARQ process, note the transmitting time first of this MAC-e PDU.

Then, enter step 902, Radio Link collection (the Radio Link Set that on arbitrary HARQ process in the user terminal, comprises the involved Serving cell of a PDU of SI, be called for short " RLS ") when successfully receiving, user terminal judges whether the 2nd PDU that comprises SI that is transmitting is arranged on other HARQ process.

Specifically, user terminal only comprises this SI to the MAC-e PDU that comprises SI that base-station node sends on each HARQ process, and does not comprise high level data, also may comprise this SI and high level data simultaneously.For only comprising this SI, and do not comprise the MAC-e PDU of high level data,, illustrate that then the SI among this MAC-ePDU sends successfully if user terminal receives the affirmation information A CK of the RLS of self-contained Serving cell; For the MAC-e PDU that comprises this SI and high level data simultaneously, if user terminal is only received the affirmation information A CK of any other RLS, illustrate that then the high level data among this MAC-e PDU sends successfully, and the SI among this MAC-e PDU loses, if user terminal had both been received the affirmation information A CK of other RLS, receive the affirmation information A CK of the RLS of self-contained Serving cell again, illustrate that then high level data and the SI among this MAC-e PDU all sends success.

Therefore, when the RLS of the involved Serving cell of a PDU that comprises SI on a certain HARQ process successfully receives, illustrate that the SI among the PDU has sent success.When the SI among the PDU sent successfully, user terminal judged whether the 2nd PDU that comprises SI that is transmitting is arranged on other HARQ process.Such as, for 2ms TTI, 8 parallel HARQ processes are arranged in user terminal, when the RLS of the involved Serving cell of a PDU that comprises SI on arbitrary HARQ process wherein successfully receives, to other 7 parallel HARQ processes check one by one judge whether the 2nd PDU that comprises SI that is transmitting is arranged on these 7 HARQ processes.If have, then enter step 903, otherwise, directly enter step 907.

In step 903, whether the SI among the 2nd PDU that the further judgement of user terminal is being transmitted is the SI report of upgrading.Specifically, because user terminal has write down the transmitting time first that comprises the PDU of SI on each HARQ process, therefore, whether the transmitting time first of the 2nd PDU that can transmit according to the further judgement of transmitting time first of the PDU on each the HARQ process that is write down is early than the transmitting time first of a PDU, if, illustrate that then the SI that is comprised among the 2nd PDU is old SI report, enter step 904, otherwise, illustrate that then the SI that is comprised among the 2nd PDU upgrades than the SI that is comprised among the PDU, directly enters step 907.

In step 904, as mentioned above, user terminal only comprises SI to the MAC-e PDU that comprises SI that base-station node sends on each HARQ process, and does not comprise high level data, also may comprise SI and high level data simultaneously.Therefore, in this step, user terminal need judge that the 2nd PDU only comprises SI and the MAC-e PDU that do not comprise high level data, still comprises the MAC-e PDU of SI and high level data simultaneously.If the 2nd PDU only comprises SI and do not comprise high level data, then enter step 905; If the 2nd PDU comprises SI and high level data simultaneously, then enter step 906.

In step 905, when the 2nd PDU only comprised SI and do not comprise high level data, user terminal stopped the re-transmission of the 2nd PDU.Because the SI that is comprised among the 2nd PDU is old SI report, and the high level data that also need not transmit among the 2nd PDU, therefore, user terminal is by stopping the re-transmission of the 2nd PDU, discard the SI that is comprised among this PDU, what both guaranteed that base-station node obtains is up-to-date SI report from user terminal, has effectively saved system resource again.

In step 906, when the 2nd PDU comprised SI and high level data simultaneously, the SI among this 2nd PDU that is transmitting of user terminal indication base-station node was invalid, discards the SI that is comprised among this PDU.Avoided because the new SI report that re-transmission caused of SI may be reported the problem that be covered by old SI, thereby guaranteed that base-station node can in time obtain the up-to-date SI report from user terminal, has also guaranteed the performance of E-DCH ascending grouping scheduling.

Specifically, user terminal is provided with and the corresponding control information of the 2nd PDU by in E-DPCCH, indicates the SI among this PDU of base-station node invalid.

Such as in the later retransmission of the 2nd PDU, the E-TFCI field among the E-DPCCH in the corresponding TTI is set to designated value, and the SI among this PDU of indication base-station node is invalid.Because in E-DCH, retransmit and always adopt the transformat (transmission block size) identical with initial transmission, E-TFC field in the re-transmission on the E-DPCCH is redundant, so, the situation that SI is transmitted with high level data, in re-transmission, can specify a specific E-TFCI value, promptly the transmitting block index SI that indicates base-station node the 2nd PDU to be comprised is invalid, be set at 0 o'clock as E-TFCI, the SI among the expression PDU is invalid.Perhaps, in the re-transmission of the 2nd PDU, specify an E-TFCI value different to indicate the SI that is comprised among this PDU invalid arbitrarily with initial transmission.User terminal is by being provided with the control signaling information of E-DPCCH in the prior art, and the SI among the corresponding PDU of indication base-station node is invalid, makes that the present invention program is easier to realize.

Then, enter step 907, when base-station node is received PDU, judge whether that the SI that is instructed among this PDU is invalid.At above-mentioned case, base-station node judges according to the E-TFCI field value in the corresponding TTI among the E-DPCCH whether the SI that is comprised among the PDU that receives is invalid, if, then directly enter step 910, otherwise, step 908 entered.

In step 908, base-station node judges whether the SI that is comprised among the 3rd PDU of current success reception is up-to-date.Specifically, because user terminal is from sending MAC-e PDU HARQ process, need the regular hour up to the feedback information that receives from this MAC-e PDU of base-station node, be RTT, this time span promptly for 2ms TTI pattern, is 16ms just in time for once retransmitting the time; For 10ms TTI pattern, be 40ms.Therefore, when user terminal knows that the RLS of the involved Serving cell of a PDU that comprises SI successfully receives, in the RTT before this, may also have other HARQ process transmitting or retransmit the MAC-e PDU that comprises SI, if and certain HARQ process has also successfully been transmitted the MAC-e PDU that comprises SI, the problem that still may cause new SI information to be replaced then by old SI information.

So, in this step, when base-station node successfully receives the 3rd PDU that comprises SI, judge that whether successfully having received other in the RTT before this on other HARQ process comprises the 4th PDU of SI, if, the number of transmissions that then compares the 3rd PDU and the 4th PDU, if it is not up-to-date SI report that the number of transmissions of the 3rd PDU, is then judged the SI among current successful the 3rd PDU that receives greater than the number of transmissions of the 4th PDU, enter step 909, otherwise, process ends.

In step 909, it is invalid that base-station node is judged to be the SI among the 3rd PDU of current success reception.Because the SI that is comprised among the 3rd PDU is not up-to-date SI report, therefore, invalid what guaranteed further that base-station node obtains is up-to-date SI report by this SI is judged to be, and has guaranteed the performance of E-DCH ascending grouping scheduling.

Then, in step 910, base-station node abandons invalid SI.Specifically, the SI that is instructed to wherein when base-station node is received PDU is invalid, or judges when SI among the received PDU is invalid, abandons the SI among this PDU, is up-to-date SI report with what guarantee to obtain, thereby has guaranteed the performance of E-DCH ascending grouping scheduling.

The transmission method and first execution mode of SI are roughly the same among the second execution mode EDCH of the present invention, its difference only is, in the first embodiment, user terminal indicates the SI among base-station node the 2nd PDU invalid by the E-TFCI field in the corresponding TTI among the E-DPCCH is set.And in the present embodiment, user terminal is by when the 2nd PDU retransmits, be set to the value of representing that SI is invalid with this PDU corresponding " Happy " bit in the E-DPCCH control information, when wherein retransmitting in the E-DPCCH control information " Happy " bit be redefined into indication SI whether effective.As to define when retransmitting " Happy " bit value be to represent that SI was effective at 0 o'clock, be to represent that SI was invalid at 1 o'clock, then can by in E-DPCCH accordingly " Happy " bit value in the TTI be set to 1, indicate the SI among base-station node the 2nd PDU invalid.

The user terminal of third embodiment of the invention comprises as shown in figure 10: the HARQ entity has at least two HARQ processes in this HARQ entity; And judge module, when the RLS that is used for comprising the involved Serving cell of a PDU of SI on arbitrary HARQ process of this HARQ entity successfully receives, comprise SI among the 2nd PDU that judges whether transmitting on other HARQ process, and the transmitting time first of the 2nd PDU is early than the transmitting time first of a PDU, if the SI that is comprised among then discarded the 2nd PDU.With what guarantee to obtain is up-to-date SI report, thereby has guaranteed the performance of E-DCH ascending grouping scheduling.

Need to prove, this judge module is in the transmitting time first of judging the 2nd PDU during early than the transmitting time first of a PDU, need further the content of carrying among the 2nd PDU to be differentiated, if comprise SI and high level data among the 2nd PDU simultaneously, then be provided with among the E-DPCCH and the corresponding control information of the 2nd PDU, the SI among indication base-station node the 2nd PDU is invalid; Do not comprise high level data if comprise SI among the 2nd PDU, then indicate this HARQ entity to stop the re-transmission of the 2nd PDU, with conserve system resources.

The base-station node of four embodiment of the invention comprises as shown in figure 11: the HARQ entity has at least two HARQ processes in this HARQ entity; And judge module, be used for when arbitrary HARQ process is successfully collected the PDU that contains SI, judge whether the control information on the E-DPCCH corresponding with this PDU indicates the SI among this PDU invalid, if, illustrate that then SI among this PDU is not up-to-date SI report, indicate this HARQ entity to abandon SI among this PDU.This judge module also is used for when arbitrary HARQ process is successfully collected the 3rd PDU that contains SI, judge in the scheduled duration before this and whether successfully received the 4th PDU that comprises SI on other HARQ process, if, the number of transmissions that then compares the 3rd PDU and the 4th PDU, if the number of transmissions of the 3rd PDU is greater than the number of transmissions of the 4th PDU, illustrate that then the SI among the 3rd PDU that current success receives is not up-to-date SI report, indicate this HARQ entity to abandon SI among the 3rd PDU.

Wherein, scheduled duration is that user terminal is from sending PDU to the time span of As-received tiny node to the feedback information of this PDU, i.e. RTT.

Need to prove, in the present invention, a PDU, the 2nd PDU, the 3rd PDU and the 4th PDU and not otherwise specified some PDU, just for the ease of understanding, the description that a class PDU is carried out.

Though pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
