Description

The method and apparatus that is used for scheduling user's set in the soft handing-over zone of up link

Technical field

The present invention relates generally to asynchronous wide-band code division multiple access (WCDMA) communication.Specifically, the present invention relates to be used for dispatching effectively the method and apparatus of the enhancing dedicated channel of using by the subscriber equipment (UE) that is positioned at soft handing-over (handover) zone that is used for uplink packet transmission.

Background technology

Universal mobile telecommunications service (UMTS) system is a 3-G (Generation Three mobile communication system), this system is based on the global system that is used for mobile communication system (GSM), this GSM is European mobile communication system, and UMTS uses Wideband Code Division Multiple Access (WCDMA) (WCDMA), provide the compatible business that can transmit packet-based text, digitized audio or video and multi-medium data, no matter where mobile phone user or computer user are positioned at 2Mbps or higher rate.UMTS uses the principle of the virtual access be called " packet switching accesss ", and this packet switching inserts the packet oriented protocol of use as Internet protocol (IP), and this UMTS is any terminal in the accesses network all the time.

Fig. 1 is the structural representation that is illustrated in the traditional UMTS terrestrial radio access network (UTRAN) in the UMTS system.With reference to figure 1, UTRAN12 comprises radio network controller (RNC) 16a and 16b and Node B 18a, 18b, 18c and 18d, and terminal and subscriber equipment (UE) 20 are connected to core net 10.Each node among Node B 18a, 18b, 18c and the 18d can have a plurality of sub-districts (cell) in its lower floor.Among this RNC16a and the 16b each is controlled at their lower floor's Node B relevant with them.For example, in Fig. 1, this RNC16a control Node B 18a and 18b, and this RNC16b control Node B 18c and 18d.Each control residential quarter relevant with them among this node 18a, 18b, 18c and the 18d.RNC and its interdependent node B and constitute radio network sub-system (RNS) 14a and 14b by the sub-district of this RNC control.

Each RNC14a and 14b distribute and manage its Node B 18a to the radio resource of 18d, and Node B 18a provides this radio resource to each node among the 18d.Each sub-district produces this radio resource, and is related to the radio resource of the sub-district of being managed by this Node B by the radio resource that Node B 18a provides to 18d.The radio resource that this UE20 can use the specific cell by specific Node B to provide produces radio channel, and uses the channel executive communication that produces.Because at Node B 18a to distinguishing between the 18d or distinguishing, and their related cell is meaningless for UE20, and UE20 only discerns the physical layer that each sub-district produces, so term " Node B 18a is to 18d " has identical meaning with " sub-district " as used herein.

Interface between UE20 and RNC16a and 16b is called the Uu interface, and Fig. 2 shows its detailed hierarchy.This Uu interface is divided into the control plane that is used to control the handshaking between UE20 and RNC16a and the 16b, and the user plane that is used for transfer of data.

With reference to figure 2, by radio resource control (RRC) layer 34, radio link control (RLC) layer 40, media interviews controls (MAC) layer 42 and physics (PHY) layer 44 processing controls plane (C-plane) signaling 30.By packet data control agreement (PDCP) layer 36, broadcast/multi broadcast control (BMC) layer 38, rlc layer 40, MAC layer 42 and PHY layer 44 process user plane (U-plane) information 32.In the layer described herein, PHY layer 44 is arranged in each sub-district, and MAC layer 42 is arranged in RNC to rrc layer 34.

This PHY layer 44 provides information transfer service by using radio transmission techniques, and corresponding to the layer 1 of open system interconnection (OSI) (OSI) model.By the connection between transmission channel realization PHY layer 44 and the MAC layer 42, and according in PHY layer 44, there being how many special datas will process to define this transmission channel.

This MAC layer 42 connects this rlc layer 40 by logic channel.This MAC layer 42 will be sent to PHY layer 44 from rlc layer 40 by excessively suitable transmission channel by the data communication device that logic channel receives, and will be sent to rlc layer 40 from PHY layer 44 by excessively suitable logic channel by the data communication device that transmission channel receives.In addition, this MAC layer 42 is inserted into additional information in the data that receive by logic channel or transmission channel, perhaps analyzes the additional information that is inserted in the data, and carries out suitable operation according to the additional information of analyzing.And, these MAC layer 42 control random access operation.At this MAC layer 42, the part relevant with user plane is called MAC-d, is called MAC-c with the part relevant with this control plane.

Foundation and the releasing of these rlc layer 40 management logic channels.This rlc layer 40 is operable in three kinds of patterns promptly permits pattern (AM), does not permit one of pattern (UM) and transparent mode (TM), and every kind of operator scheme provides different functions.Usually, this rlc layer 40 has the function of decomposing or gather the Service Data Unit (SDU) that provides from the upper strata with suitable dimensions, and error correction.

This PDP layer 36 is arranged in the upper strata of the rlc layer 40 of user plane, and have compression and decompression with the function of the head of the data of IP block form transmission and under the situation that the RNC that mobile service is provided to particular UE changes the function of lossless transmission data.

Determine PHY layer 44 is connected to the characteristic of transmission channel on its upper strata by transformat (TF), this transformat regulation physical layer process process is as the convolution chnnel coding, interweave and professional special speed coupling.

Specifically, the UMTS system uses enhanced uplink dedicated channel (E-DCH), so that strengthen the packet transmitting performance in the uplink communication of from UE to the Node B (or base station (BS)).In order to support stable high speed data transfer, this E-DCH supports such as mixed automatic retransfer request (HARQ) and controlled node B dispatching technique.The MAC-e layer of the lower floor by being arranged in the MAC-d layer realizes that this E-DCH ground processes, and in this MAC-e layer, the E-DCH data with interpolation control information wherein are called MAC-and strengthen protocol Data Unit (MAC-ePDU).

Fig. 3 is expression sends the conventional method of system for uplink packet data by the E-DCH in the radio uplink that comprises channel 111,112,113 and 114 a schematic diagram.With reference to figure 3, reference number 100 expresses support for the Node B of E-DCH and the UE of reference number 101,102,103 and 104 expression transmission E-DCH.This Node B 100 is analyzed the state of the UE101 to 104 that uses E-DCH, and dispatches the data rate of UE101 to 104 according to analysis result.In order to increase the whole system performance, carry out this scheduling by this way, promptly distribute low data rate and distribute high data rate near the UE of Node B away from the UE of Node B, if the rising overheated (Rise-over-Thermal) of the Node B of measuring (RoT) value be no more than target RoT value.

Fig. 4 is that expression is used for the signaling diagram by the conventional process of E-DCH sending and receiving message.With reference to figure 4, in step 202, Node B and UE set up E-DCH betwixt.This E-DCH sets up process 202 and comprises the process that sends message by dedicated transmission channel.After E-DCH set up, at step S204, this UE provided schedule information to Node B.This schedule information can comprise the UE transmission power information of representing uplink traffic channel information, the available excess power information of UE and the transmitted data amount of storing in the UE buffer.

In step 206, monitor the schedule information that receives from a plurality of UE from the Node B of a plurality of UE receiving scheduling information of communicating by letter, so that dispatch the data rate of each UE with Node B.Specifically, at step S208, Node B allows UE to send uplink packet and sends dispatching distribution information to UE.This dispatching distribution information comprises the maximum data rate of allowance and the transmit timing of allowance.

At step S210, this UE is by using dispatching distribution information to determine transformat (TF) at the E-DCH that transmits in the other direction.At step S212, this UE sends up link (UL) grouped data by E-DCH, and simultaneously, sends TF information at step S214 to this Node B.At step S216, this Node B determines whether there is mistake in TF information and grouped data.At step S218, if there is mistake in they any one, then this Node B sends to UE by the ACK/NACK channel and does not permit (NACK).Yet, they two do not have mistake, this Node B send to be permitted (ACK) by the ACK/NACK channel to UE.If send ACK, then finish the respective packets data transfer, and this UE sends new data by E-DCH thus.Yet if send NACK, this UE sends identical grouped data by E-DCH.

Because this E-DCH is the enhancing channel that is used for uplink packet transmission, so it has the fundamental characteristics of dedicated channel, and one of them characteristic is to support soft handing-over.Be arranged in all Node B receiving downlink information that the UE in soft handing-over zone can comprise from active set (active set).Therefore, be arranged in all Node B receiving scheduling assignment information that the UE of this soft handover region comprises from active set, in order to send E-DCH.Therefore, because all Node B that UE comprises from active set receive different scheduling assignment information, so this UE need determine whether to send E-DCH according to different scheduling assignment information.

As mentioned above, in the communication system of the routine of supporting E-DCH, dispatch the UE that is arranged in soft handing-over zone in this mode, all Node B that this mode promptly comprises in active set send the scheduling assignment information to UE, are causing additive decrementation (overhead) problem aspect code resource or the power delivery resource.In addition, the UE that receives different dispatching distribution information has difficulties when determining whether to send E-DCH.

Summary of the invention

Embodiment

To describe a plurality of exemplary embodiments of the present invention with reference to the accompanying drawings in detail.In the following description, for the sake of simplicity, omitted the detailed description in this known function that comprises and configuration.

Embodiments of the invention provide improved dispatching technique, be used to be reduced to the downlink signaling amount of information that the scheduling of subscriber equipment (UE) produces, this UE is arranged in the soft handing-over zone of enhanced uplink Packet data service, determine the transformat (TF) of enhanced uplink dedicated channel (EDCH) clearly, and manage uplink resource effectively.In addition, embodiments of the invention provide and are not by optimal scheduling Node B (below be called " serving node B "), but the dispatching technique that starts by other Node B that is included in active set (below be called " non-serving node B ").And embodiments of the invention provide a kind of method, and the UE that wherein is arranged in soft handing-over zone is from this serving node B receiving scheduling assignment information with from non-serving node B receiving scheduling assignment information, and the scheduling assignment information of analysis reception.

Although embodiments of the invention described here will suppose to be authorized by each Node B the scheduling authority of UE, embodiments of the invention also can be applicable to the situation that the scheduling authority of UE is authorized by each sub-district.In this case, the active set that will be understood that UE comprises optimal scheduling sub-district and one or more non-optimal schedulings sub-district.

The dispatching method that is used for uplink packet transmission can be divided into a plurality of methods.This typical dispatching method comprise the rate scheduling method and time-and-the rate scheduling method.In the rate scheduling method, Node B is controlled the data rate of each UE step by step.Time-and-the rate scheduling method in, Node B is controlled the time and the speed of the uplink packet transmission that is used for UE simultaneously.This two dispatching methods will be described below.

Fig. 5 is that expression is used to send up link and the down link control information that is used for rate scheduling, and sends the method schematic diagram of uplink packet.

With reference to figure 5, UE502 rate request information 505 and E-DCH data 506, and Node B sends expression by the rate grants information 503 of scheduling permission to the UE502 maximum rate.This rate grants information 503 can be represented in speed rising, speed decline and the speed maintenance.

This UE502 determines ul transmissions data volume in its buffer and available excess power, and rises/lower request to Node B 501 transmission rates by this rate request information 505 according to the result who determines, in order to the next speed that needs is set.It is synthetic from this UE502 and the rate request information that sent by other UE of this Node B 501 controls to receive the Node B 501 of this rate request information 505, determine whether to increase, reduce or keep the maximum rate of this UE502 according to synthetic result, and by using rate grants information 503 will determine that result notification gives UE502.

With reference to the concrete example among the figure 5, in step 508, this UE502 is by using rate request information 507 transmission rates-upper request to increase its speed.In step 510, receive the Node B 501 of this rate request information 507 after scheduling, by using rate grants information 509 to this UE502 transmission rate-upper sign.In response, this UE502 can send uplink packet with speed 11 (512), and this speed 11 increases one-level (511) than former speed 10.

In above-mentioned rate scheduling, Node B and UE had the rate information that UE can use in the past.For example, can utilize the transmission block comprehensive (TBC) that is illustrated in the transmission block size (TBS) of using among the WCDMA to represent this rate information.

Fig. 6 be expression be used to transmit be used for time-and-up link and the down link control information of rate scheduling, and transmit the method schematic diagram of uplink packet.

With reference to figure 6, UE603 periodically or with event starts the basis to Node B 601 transmission UE status informations 604, and this information is included in the information of the data volume of storing in its buffer and the information of through-put power.This Node B 601 depends on UE status information 604, is identified for the maximum rate of the next duration use of UE603 by scheduling, and passes through the maximum rate that use dispatching distribution (SA) information 602 notice UE603 determine.As response, this UE603 sends E-DCH data 605 with the maximum rate by these dispatching distribution information 602 expressions in the reverse direction in the scheduled time.

For example, UE603 at first uses speed 1 (610) to be used for the transmission of E-DCH data 605.In step 621, if this UE603 sends UE state information 611 to Node B 601, then these Node B 601 operation dispatchings are to determine whether to permit (grant) E-DCH transmission for the next duration of UE603.If Node B 601 determines to permit the E-DCH transmission, then it determines to permit being used for the speed of UE, and determines to permit the temporal information of transmission.In step 641, this Node B 601 is by using dispatching distribution information 631 to send (allowance) timing information of distribution and the rate information of distribution (allowance) to UE603.This UE603 that receives this dispatching distribution information 631 sends the E-DCH data according to the speed 10 (651) of distributing in based on the time of dispatching distribution information 631.Yet if this Node B 601 is not distributed the duration to UE603, shown in reference number 630, this UE603 sends E-DCH data 605 by the speed 1650 of using minimum-rate.

Use rate scheduling and time-and-situation of rate scheduling under, usually use the rate scheduling based on rate grants information.If because the generation of data or exhaust and need unexpected rate of change and change suddenly channel condition, then can use based on rate grants information time-and-rate scheduling.

Fig. 7 is the enhanced uplink Packet data service is carried out in expression by the UE that is arranged in soft handing-over zone a operation chart.

In Fig. 7, UE703,706 and 710 can send the E-DCH data.This UE710 is arranged in soft handover region, and the

Node B

701 and 702 relevant with soft handover region is included in the active set of UE710.UE703 and 706 is not arranged in soft handover region, and only communicates by letter with 702 with their Node B 701 respectively.This UE703 is from Node B 701 receiving scheduling assignment information, and sends E-DCH data 705 to Node B 1701.Equally, this UE706 is from Node B 2702 receiving scheduling assignment information, and sends E-DCH data 708 to Node B 2702.

This UE710 that is arranged in soft handing-over zone has the

Node B

701 and 702 at its active set, and from Node

B

701 and 702 receiving scheduling assignment information.The Node B 701 that comprises in the active set of UE710 can be with the scheduling of identical method execution to UE710 with 702.Preferably, this Node B 701 can be with the scheduling of different scheduling authority execution to UE710 with 702.In this case, have Node B for the maximum of UE710 scheduling authority and become serving node B (or optimal scheduling Node B) for UE710.

For UE710, select a serving node B in the

Node B

701 and 702 from be included in this active set.For example, according to sending the noise that receives in the process of E-DCH data, the most affected Node B of UE710 is defined as serving node B in the other direction.Usually, with the Node B of the most close UE710, the Node B that has the Node B of best uplink and downlink channel status and have a residue uplink resource is defined as serving node B.

In Fig. 7, this Node B 701 is the serving node B that are used for UE710, and Node B 702 is the non-serving node B that are used for UE710.This UE710 receives the

signal

711 and 713 that sends from this serving node B 701 and non-serving node B702, and serving node B 701 and non-serving node B702 also receive the

signal

712 and 714 that is sent by UE710.

If serving node B 701 and non-serving node B702, then must increase owing to the consumption of downlink signaling through-put power and code resource to the dispatching distribution information that are included in all UE in the active set and send them by relevant dedicated signaling.Therefore, in this case,

Node B

701 and 702 lacks through-put power or available channel code.In fact, communicate by letter with 702 with two or more Node B 701 that active set at it comprises if be arranged in the UE710 of soft handover region, then the downlink signaling information downlink signal strength very high according to its characteristic needs.Therefore, above-mentioned through-put power and code resource consumption problem will become more important.

As the method that is used for addressing this problem, the dispatching distribution method that proposes in the embodiment of the invention is described referring now to Fig. 7.

In Fig. 7, the authority that non-serving node B when serving node B 701 has than the scheduling that is used for UE710 in execution 702 is higher.That is, this serving node B 701 can be carried out scheduling to UE710 in more detailed and accurate mode, and compares with serving node B 710, and non-serving node B702 can only carry out the scheduling to UE710 roughly.Therefore, the specific schedule that this serving node B 701 is carried out UE710, and this non-serving node B702 and the common scheduling of other Node B execution to UE710.This common dispatching distribution method can reduce down-chain resource consumption and solve through-put power or the code resource shortage problem of this non-serving node B702.

Fig. 8 is the schematic diagram of expression according to the common scheduling batch operation of the Node B of the embodiment of the invention.

With reference to figure 8, UE1804 and UE2805 are arranged in their soft handover region.This UE1804 management comprises the active set of Node B 1801, Node B 2802 and Node B 3803, and this Node B 1801 is the serving node B that are used for UE1804.This UE2805 management comprises the active set of Node B 2802, Node B 3803, and this Node B 3803 is the serving node B that are used for UE2805.In the E-DCH scheduling process, this serving node B is dispatched their UE by using own special-purpose signaling, and non-serving node B is dispatched all UE by using ordinary signaling.In this case, can use rate scheduling and time-and-rate scheduling or one of them.That is, this Node B 1801 sends specific schedule assignment information 806 to UE1804, and Node B 3803 also sends specific schedule assignment information 807 to UE2805.

Yet because for UE1804 and UE2805, Node B 2802 is non-serving node B, so it is by using 808 couples of UE1804 of single common dispatching distribution information and UE2805 to carry out common scheduling.That is, in the active set that the Node B 2802 as non-serving node B comprises, this Node B 802 is sending common dispatching distribution information 808 to UE84 and 805 along forward.These common dispatching distribution information 808 expressions are used for the maximum uplink speed of all UE804 and 805.This UE804 and 805 receives the common dispatching distribution information 808. that sends from this Node B 2802

Because UE1804 is set to non-serving node B with Node B 3803, so it receives the common scheduling assignment information 809 that sends from Node B 3803.In the active set that the Node B 3803 as non-serving node B is comprised, the common scheduling assignment information 809 that sends from this Node B 3803 is the information that UE805 must receive with other UE except UE1804.Receive the comprehensive one or more special uses of UE and the common dispatching distribution information of this dispatching distribution information from one or more Node B, determine thus the transformat of the E-DCH that each UE can send.

As mentioned above, the UE that is arranged in soft handover region receives the specific schedule assignment information from serving node B, and receives common dispatching distribution information from non-serving node B, and the comprehensive two or more dispatching distribution information of this UE, determines thus the transformat of E-DCH.With reference to embodiments of the invention, use the method for analyzing two or more scheduling assignment information from the method for the common scheduling assignment information of non-serving node B and the UE that is arranged in soft handing-over zone to be described in detail to UE.

First embodiment

According to the first embodiment of the present invention, non-serving node B is by using two grades (level) to carry out common scheduling.Serving node B is carried out the independent specific schedule to each UE, and non-serving node B carries out the common scheduling to a plurality of UE.That is, serving node B use rate scheduling and time-and-in the rate scheduling one or two be used for specific schedule, and use other available dispatching method for other situation.Yet non-serving node B uses the scheduling rates that scheduling is permitted indicating based on 1 bit to be used for common scheduling.If the scheduling of 1 bit is permitted sign as common dispatching distribution information, then might avoid the waste of Node B through-put power and channel code resource.

Two grades of for example, permitting the sign expression by 1 bit scheduling represent to descend (Down) signal and irrelevant (Don ' t Care) signal.If permitting sign, the scheduling of this 1 bit has real-valued "+1 " in the physical channel, then should sign expression dropping signal, if it has real-valued " 1 " in the physical channel, then sign expression irrelevant signal (Don ' t Care) is permitted in this 1 bit scheduling.In other cases, the opposite meaning of this real-valued expression.

The frequency of occurrences that can be by considering this dropping signal and the frequency of occurrences of this irrelevant signal are shone upon real-valued that this scheduling permits indicating.That is, if the frequency of occurrences of a signal is contemplated to height, then be mapped as real-valued " 0 ", this is used discontinuous transmission (DTX) in physical channel, the transmission of this signal has reduced the power consumption in the physical channel, helps reducing of through-put power and noise.At this, term DTX is meant for this corresponding duration and does not transmit basically.For example, if be higher than dropping signal according to frequency of occurrences irrelevant signal on mean value, then before sending, irrelevant signal is mapped as real-valued " 0 " in the physical channel, this dropping signal was mapped as real-valued "+1 " (or-1) in the physical channel before sending.In this case, receiver uses two signals of non-zero reference value difference.

The common dispatching distribution method of being carried out by non-serving node B will be described now.

In the process of operation dispatching, Node B is by measuring the receiving intensity management uplink resource of the UE that comprises in the coverage of Node B.The UE that Node B is set is non-serving node B has very high receiving intensity.Therefore, be subjected to very big influence if having as the UE of the Node B of serving node B or the UE that only is included in the Node B in the active set, then this Node B is provided for all UE or Node B is set permitting being masked as dropping signal from the scheduling as the UE of non-serving node B.On the contrary, if receiving intensity affects little to Node B and Node B has the residue uplink resource, then this Node B is set to irrelevant signal for the scheduling allowance sign of UE.

According to the structural representation of the UE of first embodiment of the invention in Fig. 9.This UE is arranged in soft handover region, and has a serving node B and one or more non-serving node B.

With reference to figure 9, UE receives specific schedule assignment information 901 from serving node B.This specific schedule assignment information 901 becomes rate grants (RG) signal that is used for this rate scheduling method, become be used for time-and-scheduling of rate scheduling method distributes (SA) signal, and becomes the comprehensive of the rate grants signal of the integrated approach that is used for two kinds of methods and scheduling distributing signal.This UE reception receives n scheduling allowance value 902 to 903 from non-serving node B, and (at this, ' n ' represents the integer more than or equal to 1.) at this, scheduling allowance value refers to dispatch the real-valued of allowance sign.Comprehensive function actuator 904 comprehensive n scheduling allowance values 902 to 903 are permitted in the scheduling that is used for non-serving node B, and determine a comprehensive scheduling allowance value 905.To describe below scheduling in detail and permit the operation of comprehensive function actuator 904.

To be input to scheduling decision-making function actuator 906 together with the specific schedule assignment information 901 that receives from this serving node B from the comprehensive scheduling allowance value 905 that n scheduling allowance value 902 to 903 obtained, and should the definite function executor 906 of scheduling determine that by UE be the required final dispatching distribution value 908 of transformat (TF) of determining E-DCH, E-DCH TF determinant 907 is by using the dispatching distribution value 908 of being determined by this scheduling decision-making function actuator 906 to be identified for the employed E-DCHTF of ul transmissions.In corresponding to these dispatching distribution value 908 maximum rates, determine E-DCH TF.The operation of scheduling decision function actuator 906 will be described in detail belows.

When the quantity of non-serving node B greater than 2 the time, comprehensive function actuator 904 is permitted in the scheduling of Fig. 9 can carry out following operation.

As an example, if value representation (Down) signal that descends is permitted in any one scheduling that is received by this UE, the comprehensive scheduling allowance value 905 that then should scheduling allowance comprehensive function actuator 904 be identified for non-serving node B is dropping signal.That is, have only when this irrelevant signal of value representation is permitted in all scheduling, the comprehensive scheduling allowance value 905 that this scheduling allowance comprehensive function actuator 904 just is identified for non-serving node B is irrelevant signal.Otherwise the comprehensive scheduling allowance value 905 that this scheduling allowance comprehensive function actuator 904 is identified for non-serving node B is dropping signal.

As another example, this scheduling is permitted comprehensive function actuator 904 and is come comprehensive scheduling allowance value from non-serving node B by using weighted sum.At this, this weighted sum refers to use the weighted value that arranges separately into this non-serving node B.With reference to Figure 10 in detail, the structure of permitting comprehensive function actuator 904 for the comprehensive scheduling of weighted sum of scheduling allowance value will be described.

With reference to Figure 10, if receive n

scheduling allowance value

1001,1002 and 10003 from n non-serving node B, then this scheduling allowance value 1001 to 1003 multiplies each other with the

weighted value

1005,1007 and 1009 of being scheduled to respectively by

multiplier

1006,1008 and 1010, then by adder 1011 summations.According to the residential quarter geometry, will be arranged on for the weighted value that non-serving node B determines respectively in this network as RNC, and offer then UE.As an alternative, UE arranges in inside according to the channel status to Node B.

Specifically, the scheduling allowance value 1001 that receives from the first non-serving node B multiplies each other with the weighted value W1 (1005) that is the first non-serving node B setting multiplier 1006, inputs to adder 1011 then.The scheduling allowance value 1002 that receives from the second non-serving node B multiplies each other with the weighted value W2 (1007) that is the second non-serving node B setting multiplier 1008, inputs to adder 1011 then.The scheduling allowance value 1003 that receives from the non-serving node B of n multiplies each other with the weighted value Wn (1009) that is the non-serving node B setting of n multiplier 1010, inputs to adder 1011 then.In this mode, the scheduling allowance value that receives from all non-serving node B multiplies each other with relevant weighted value 1005 to 1009 respectively, is input to then adder 1011.

This adder 1011 is by producing the summation weighted value to the scheduling allowance value summation of multiply by weighting 1005 to 1009.Comprehensive scheduling allowance value generator 1012 is determined comprehensive scheduling allowance value 905 according to this summation weighted value.For example, comprehensive scheduling allowance value generator 1012 relatively comes to determine comprehensive scheduling allowance value 905 according to this summation weighted value and pre-determined reference value.Permit sign expression dropping signal if having real-valued '+1 ' scheduling, and the scheduling allowance sign expression irrelevant signal with real-valued ' 1 ', then this reference value becomes ' 0 '.Therefore, if the summation weighted value more than or equal to ' 0 ', then this comprehensive scheduling allowance value 905 becomes dropping signal, and if the weighted value of suing for peace less than ' 0 ', then this comprehensive scheduling allowance value 905 becomes irrelevant signal.As another example, if dropping signal be real-valued ' 0 ' and this irrelevant signal be real-valued '+1 ' (or ' 1 '), then this reference value will become for '+0.5 ' (or ' 0.5 ').

The scheduling decision-making function actuator 906 of Fig. 9 receives the dispatching distribution information 901 that the integrated dispatch allowance value 905 determined and UE receive from this serving node B, and output scheduling apportioning cost 908, so that UE can determine the TF of the E-DCH that will send.If integrated dispatch allowance value 905 expression irrelevant signals, even then the E-DCH TF of UE changes to a certain extent, the non-serving node B of UE can not be subjected to big influence during the line link resource in the use yet.Therefore, this UE determines E-DCH TF according to the specific schedule assignment information 901 that is sent by this serving node B.

Yet, if 905 expressions of comprehensive scheduling allowance value descend, mean that the E-DCH transmission of UE is used in the uplink resource as heavy duty at non-serving node B.This decline refers to be used for speed is reduced the instruction of one-level when this rate scheduling is used for the E-DCH transmission, and when time-and-rate scheduling is used for limiting the instruction of the transmission of E-DCH when being used for the E-DCH transmission.

If all UE that are arranged in soft cross-connecting area reduce one-level according to this dropping signal with the speed of E-DCH and rise in this speed and to determine the TF of E-DCH, perhaps limit the transmission of E-DCH, then do not consider the independent state of UE, reduce performance and the fairness of system.In order to address this problem, selective descending method below can using.

At first, in probabilistic decline decision method, if the probable value that produces by probabilistic testing more than or equal to predetermined value, then UE follows the decline judgement of integrated dispatch allowance value 905.Otherwise this UE ignores the decline of (disregarde) integrated dispatch allowance value 905 and judges.When the decline of ignoring integrated dispatch allowance value 905 was judged, this UE used the complete form of the former frame in the process of the form of determining E-DCH, perhaps follows the specific schedule assignment information 901 from serving node B.

When using rate scheduling, second method determines whether to accept to descend to judge according to the present rate of UE.This UE has rate-valve value.When if the present rate of E-DCH is greater than or equal to threshold value, non-serving node B is subjected to the very big influence of the E-DCH transmission of UE.Therefore, this UE follows the decline judgement of integrated dispatch allowance value 905.Yet if the present rate of E-DCH is lower than this threshold value, it is little that this non-serving node B is subjected to the influence of E-DCH transmission of UE.Therefore, UE keeps the complete speed of frame in the past, rather than follows the decline judgement of integrated dispatch allowance value 905, perhaps follows the specific schedule assignment information 901 from serving node B.

Third method determines whether to accept this decline judgement according to the class of service of the E-DCH that is used for UE.But provide the UE initial allocation class of service of E-DCH business, and this classification is represented the E-DCH quality of service of UE.The standard of dividing classification can be record keeping option or the channel status of UE user's selection.

For example, use specific schedule assignment information 901 whether to receive this dropping signal, and the UE with low classification reduce one-level according to whether receiving dropping signal with E-DCH speed from this serving node B no matter have other UE of higher-class.As another example, this UE has different probability threshold values according to this classification.If the probable value that produces by probabilistic testing is more than or equal to probability threshold value, then UE follows the decline judgement of integrated dispatch allowance value 905.Otherwise this UE ignores the decline of integrated dispatch allowance value 905 and judges.When the decline of ignoring integrated dispatch allowance value 905 was judged, this UE used the complete form of the former frame in the format procedure of determining E-DCH, perhaps follows the specific schedule assignment information 901 from serving node B.

The classification information of each UE can be sent to Node B.Can this classification information directly be sent to Node B by network, perhaps send to UE by the UE that sets up in the process at initial channel.When Node B had the classification knowledge of UE, the dispatching distribution information how many UE are this Node B can have to follow Node B by all UE that estimate to be arranged in soft handover region was come the selection scheduling assignment information.

In cubic method, the UE that receives the E-DCH business receives the signaling of method of dropping signal that is used to analyze non-serving node B from RNC respectively.That is, this RNC for example dispatches decision-making function and notifies to each UE by using the RRC signaling in the method for soft during handover analysis from the dropping signal of non-serving node B reception, and UE is by using the RNC signaling information to determine the speed of E-DCH.

For example, this RNC has ' 1 ' or ' 0 ' scheduling decision-making function to the UE notice according to the state of UE.Receive ' 1 ' UE by signaling and use specific schedule assignment information 901, no matter whether receive dropping signal from this serving node B.Yet, receive the dropping signal that ' 0 ' UE response receives by signaling E-DCH speed reduced one-level.As another example, this RNC is used for the threshold value of the probabilistic testing on the soft handover region to each UE notice.When non-serving node B sends dropping signal, if the probable value that produces by probabilistic testing more than or equal to this threshold value, then the UE decline of following integrated dispatch allowance value 905 is judged, otherwise this UE ignores the decline judgement of integrated dispatch allowance value 905.When the decline of ignoring integrated dispatch allowance value 905 was judged, this UE used the complete form of the previous frame in the process of determining the E-DCH form, perhaps uses the specific schedule assignment information 901 from serving node B.

By sending to UE, or even the signaling information of Node B, the scheduling of this RNC on can more effective XM B.Namely, this Node B has the knowledge of the analytical method in this situation, this situation namely, receive dropping signal from non-serving node B at soft during handover UE, and come the selection scheduling assignment information by the dispatching distribution information how many UE the UE that estimates to be arranged in soft handover region has to follow Node B.

Except above-mentioned two kinds of methods, this scheduling decision-making function actuator 906 is permitted sign 902 to 903 and is provided various comprehensive from the specific schedule assignment information 901 of this serving node B by using from the scheduling of non-serving node B, and according to this comprehensive output scheduling apportioning cost 908.The output of this scheduling decision-making function actuator 906 becomes the final schedule information for the E-DCH that is sent by UE, and this UE is by using this schedule information to determine the TF of E-DCH.

Second embodiment

According to a second embodiment of the present invention, non-serving node B is by using three level of signal to carry out common scheduling.That is, this non-serving node B proposes the Three Estate of dropping signal, critical (Marginal) dropping signal and have the irrelevant signal that sign is permitted in scheduling.Serving node B is carried out specific schedule by specific schedule assignment information independently to each UE, and non-serving node B permits sign by a scheduling and carries out common scheduling to a plurality of UE.This serving node B use rate scheduling and time-and-in the rate scheduling one or two be used for specific schedule, perhaps use all other possible dispatching methods.Yet the common scheduling of non-serving node B uses this scheduling to permit sign, with three rank co-controlling speed.

Have real-valued '+1 ' time in the physical channel when permit sign based on the scheduling of this common scheduling, it represents dropping signal, when it has real-valued ' 1 ' time in the physical channel, it represents irrelevant signal, and when it stands DTX, promptly have real-valuedly ' 0 ' time, represent critical dropping signal.In other situation, three values '+1 ', ' 1 ' and ' 0 ' can be by different way and above-mentioned signal synthesis.

For example, consider to be used for the frequency of occurrences of each dropping signal, irrelevant signal and critical dropping signal, this real-valued this scheduling allowance sign that is mapped as.That is,, then be mapped as real-valued " 0 ", this is used DTX in physical channel if the frequency of occurrences of a signal is contemplated to height.At this, DTX is meant for the corresponding duration and does not transmit substantially.Power consumption in the signaling reduction physical channel that does not transmit on the basis helps the reduction of through-put power and noise.For example, if be higher than dropping signal and critical dropping signal according to frequency of occurrences irrelevant signal on mean value, then do not transmitting on the basis, before irrelevant signal sends, UE is mapped as real-valued " 0 " in the physical channel with it, and this dropping signal was mapped as real-valued "+1 " (or-1) in the physical channel before sending.Before critical dropping signal sends, it is mapped as real-valued ' 1 ' (or '+1 ') in the physical channel.

To the common dispatching distribution method of being carried out by non-serving node B be described.

In the operation dispatching process, Node B is by measuring the receiving intensity management uplink resource of the UE that comprises in the coverage of Node B.The UE that Node B is set is non-serving node B has very high receiving intensity.Therefore, be subjected to very big impact if having as the UE of the Node B of serving node B or the UE that only is included in the Node B in the active set, then the scheduling that is provided for UE of this Node B permits being masked as dropping signal.On the contrary, if receiving intensity affects little to Node B and this Node B has the residue uplink resource, then this Node B is set to irrelevant signal for the scheduling allowance sign of UE.In addition, this receiving intensity has to a certain degree impact to Node B, if but non-serving node B is in the use relatively free in the line link resource, perhaps this Node B has the residue uplink resource by the uplink degree transmission that limits UE fully, and then this Node B permits being set to critical dropping signal for the scheduling of UE.That is, compare with dropping signal, this critical dropping signal represents seldom to force to reduce uplink rate.

Referring now to the operation of Fig. 9 description according to the UE of second embodiment of the invention.The UE that is arranged in soft handing-over zone has a serving node B and one or more non-serving node B.

With reference to figure 9, UE receives specific schedule assignment information 901 from serving node B.Specific schedule assignment information 901 becomes rate grants (RG) signal that is used for this rate scheduling method, become be used for time-and-scheduling of rate scheduling method distributes (SA) signal, and become the rate grants signal of the integrated approach that is used for these two kinds of methods and this scheduling distributing signal comprehensively.This UE receives n scheduling allowance value 902 to 903 (representing integer more than or equal to 1 at this ' n ') from the non-serving node B of n.At this, this scheduling allowance value refers to dispatch the real-valued of allowance sign.Comprehensive function actuator 904 comprehensive n scheduling allowance values 902 to 903 are permitted in this scheduling that is used for non-serving node B, and determine a comprehensive scheduling allowance value 905.To describe below scheduling in detail and permit the operation of comprehensive function actuator 904.

This comprehensive scheduling allowance value 905 that to from n scheduling allowance value 902 to 903, obtain and be input to from the specific schedule assignment information 901 of this serving node B reception and dispatch decision-making function actuator 906, and should determine the required final dispatching distribution value 908 for the transformat (TF) of determining E-DCH by UE by scheduling decision-making function actuator 906, and E-DCH TF determinant 907 is by using the dispatching distribution value 908 of being determined by this scheduling decision-making function actuator 906 to be identified for ul transmissions E-DCH.In corresponding to the maximum rate of this dispatching distribution value 908, determine this E-DCH.In addition, will describe the operation of this scheduling decision-making function actuator 906 below in detail.

As an example, this scheduling is permitted 904 uses of comprehensive function actuator with reference to method to set up, and this method utilizes dropping signal as preferential reference.That is, if any one the scheduling allowance value 902 to 903 that is received by UE represents dropping signals, then this scheduling allowance comprehensive function actuator 904 is identified for the scheduling allowance value of non-serving node B as dropping signal.If not dispatching the allowance value is dropping signal, then should scheduling permit the critical dropping signal of comprehensive function actuator 904 uses as next reference.Namely, if neither one is dropping signal in the scheduling allowance value 902 to 903 of being accepted by this UE, if but in them any one represents critical dropping signal, then should scheduling permit comprehensive function actuator 904 and determine that comprehensive scheduling allowances value 905 be critical dropping signal.At last, if all scheduling allowance values that received by UE are irrelevant signals, the integrated dispatch allowance value 905 that then should scheduling allowance comprehensive function actuator 904 be identified for non-serving node B is irrelevant signal.

As another example, this UE comprehensively is used for the scheduling allowance value of non-serving node B by using weighted sum.At this, this weighted sum refers to use the weighted value that arranges separately into this non-serving node B.With reference to Figure 10, with the weighted sum integrated approach that weighted sum is permitted in scheduling that is used for that describes in detail according to second embodiment of the invention.

With reference to Figure 10, if receive n

scheduling allowance value

weighted value

1005,1007 and 1009 of being scheduled to respectively by

multiplier

1006,1008 and 1010, then by adder 1011 summations.This adder 1011 produces the summation weighted value by the scheduling allowance value that multiply by this weighting 1005 to 1009 is sued for peace.Comprehensive scheduling allowance value generator 1012 is determined comprehensive scheduling allowance value 905 according to this summation weighted value.

Compare the scheduling allowance value 905 of determining that this is comprehensive by will sue for peace weighted value and 2 pre-determined reference value.For example, permit sign expression dropping signal if having real-valued '+1 ' scheduling, then have real-valued ' 0 ' scheduling and permit the critical dropping signal of sign expression, permit sign expression irrelevant signal with scheduling, and the reference value of this summation weighted value comparison becomes a value (first value) and another value between ' 0 ' and ' 1 ' (second value) between '+1 ' and ' 0 ' with real-valued ' 1 '.Therefore, if the summation weighted value, determines then that comprehensive scheduling allowance value 905 be dropping signal greater than this first value, and if the summation weighted value less than second value, determine that then it is irrelevant signal that this integrated dispatch allowance is worth 905.If the weighted value scope of should suing for peace between first value and second value, determines then that this integrated dispatch allowance value 905 is critical dropping signal.The value that this first value and second value can be predetermined value, provide by signaling from RNC and the value selected by UE any one.

As another example, this scheduling is permitted comprehensive function actuator 904 with the integrated approach operation of above-mentioned two kinds of examples.Specifically, if in this scheduling allowance value 902 to 903, have any dropping signal, should scheduling allowance comprehensive function actuator 904 preferential definite these integrated dispatch allowance values 905 be dropping signal then, if there is no dropping signal, it determines this integrated dispatch allowance value 905 by the weighted sum method that use is used for critical dropping signal and irrelevant signal.At this, by using ' 0 ' and ' reference value between-1 ' is distinguished critical dropping signal nothing to do with signal.

This scheduling decision-making function actuator 906 of Fig. 9 receives integrated dispatch allowance value 905 and the specific schedule assignment information 901 of determining, this specific schedule assignment information receives from serving node B at UE, and output scheduling apportioning cost 908 is so that this UE can determine the TF of the E-DCH that will send.If 905 expressions of this integrated dispatch allowance value are irrelevant, even then the E-DCH TF of UE changes to a certain extent, the impact that the non-serving node B of this UE is subjected to during the line link resource in the use is little.Therefore, this UE determines E-DCH TF according to the specific schedule assignment information 901 that is sent by this serving node B.

Yet, if 905 expressions of this integrated dispatch allowance value descend, the heavy duty of the E-DCH transmission that means UE during as the uplink resource that used by this non-serving node B.Therefore, according to dropping signal, this UE unconditionally reduces one-level with the maximum rate of the permission of E-DCH, and determines the TF of the E-DCH of this speed.

At last, if the critical decline of comprehensive scheduling allowance value 905 expressions, the relative heavy duty when the E-DCH transmission that then means UE can be the uplink resource that is used by non-serving node B.That is this integrated dispatch allowance value 905 this non-serving node of the expression B that, represent critical decline be used for the instruction of rate reduction one-level (being used for this rate scheduling) and be used for restriction E-DCH transmission (be used for time-and-rate scheduling) instruction send to all UE or they are set to the UE of non-serving node.Therefore, as the dropping signal in this first embodiment, this critical dropping signal uses the descending method of lower column selection.

At first, in probability decline decision method, if the probable value that produces by probabilistic testing more than or equal to predetermined value, then this UE analyzes the rate reduction one-level of E-DCH the critical decline of this integrated dispatch allowance value 905 and judges as the judgement that descends.Otherwise this UE ignores this integrated dispatch allowance value 905.When this integrated dispatch allowance of ignorance was worth 905, this UE used the complete form of the previous frame in the process of determining the E-DCH form, or followed the specific schedule assignment information 901 from this serving node B.

When using rate scheduling, second method determines whether to accept critical decline judgement according to the present rate of UE.This UE has predetermined rate-valve value.If the present rate of this E-DCH is more than or equal to threshold value, the influence that then non-serving node B is transmitted by the E-DCH of UE is very big.Therefore, this UE reduces one-level with the speed of E-DCH, analyzes the critical decline of this integrated dispatch allowance value 905 and judges as the judgement that descends.Yet if the present rate of this E-DCH is lower than this threshold value, the influence that this non-serving node B is transmitted by the E-DCH of UE is little.Therefore, UE keeps the complete speed of previous frame, ignores this integrated dispatch allowance value 905, or follows the specific schedule assignment information 901 from this Node B.

In third method, the UE that receives the E-DCH business uses the classification of initial allocation.This classification can be the classification for the quality of the E-DCH of UE, and can carry out according to this classification for the method for determining this E-DCH speed.Be used for dividing such other standard selection record keeping option or the channel status that can be UE user.This UE has predetermined classification, and operates in the following manner according to this classification when receiving in abutting connection with dropping signal.

Has other UE use of higher-class from the specific schedule assignment information 901 of this serving node B and no matter whether receive this critical dropping signal, but the UE with low classification with E-DCH rate reduction one-level, determines that the critical dropping signal of reception is dropping signal when receiving this critical dropping signal.As another example, this UE has different probability threshold values according to this classification.If pass through the probable value of this probabilistic testing generation more than or equal to this probability threshold value, then this UE analyzes the dropping signal that this critical dropping signal is this integrated dispatch allowance value 905.Otherwise this UE ignores this integrated dispatch allowance value 905.When the allowance of ignorance integrated dispatch was worth 905, this UE used the complete form of the previous frame in determining the E-DCH format procedure, perhaps follows the specific schedule assignment information 901 from serving node B.

In cubic method, the UE that receives the E-DCH business receives the signaling of method of critical dropping signal that is used to analyze non-serving node B from RNC respectively.That is, this RNC for example will dispatch decision-making function and notify each UE, and this UE is by using the speed of determining E-DCH from the signaling information of RNC by using the RRC signaling in the method for soft during handover analysis from the critical dropping signal of non-serving node B reception.

For example, this RNC has ' 1 ' or ' 0 ' scheduling decision-making function to the UE notice according to the state of UE.For this critical dropping signal is irrelevant signal, receives ' 1 ' UE by signaling and uses complete specific schedule assignment information 901 from this serving node B.Yet.For this critical dropping signal is dropping signal, receives ' 0 ' UE by signaling E-DCH speed is reduced one-level.As another example, this RNC is used for the threshold value of the probabilistic testing on the soft handover region to each UE notice.When non-serving node B sends critical dropping signal, if the probable value that produces by probabilistic testing is more than or equal to the threshold value by the RNC notice, then UE determines that the critical dropping signal of this integrated dispatch allowance value 905 is dropping signal, otherwise this UE ignores integrated dispatch allowance value 905.When the allowance of ignorance integrated dispatch was worth 905, this UE used the complete form of the previous frame in the process of determining the E-DCH form, perhaps uses the complete specific schedule assignment information 901 from serving node B.

This RNC can come scheduling on the XM B more effectively by sending the signaling information will send to UE (or even Node B).Namely, this Node B has the knowledge of the analytical method in a kind of situation, this situation namely, receive critical dropping signal from non-serving node B at soft during handover UE, and come the selection scheduling assignment information by the dispatching distribution information how many UE the UE that estimates to be arranged in soft handover region has to follow Node B.

Except above-mentioned two kinds of methods, this scheduling decision-making function actuator 906 is permitted sign 902 to 903 and is provided various comprehensive from the specific schedule assignment information 901 of this serving node B by using from the scheduling of non-serving node B, and according to this comprehensive output scheduling apportioning cost 908.The output of this scheduling decision-making function actuator 906 becomes the final schedule information for the E-DCH that is sent by UE, and this UE uses this schedule information to determine the TF of E-DCH.

A kind of method has been described, wherein Node B is dispatched the UE that is arranged in soft handover region by the allowance of the scheduling in two embodiment sign, and each UE is by using the TF that permits indicating and determining from the specific schedule assignment information that this serving node B receives E-DCH from the scheduling of non-serving node B reception.This first embodiment represents that the scheduling in two grades in dropping signal and the irrelevant signal permits sign, and sign is permitted in this second scheduling of implementing to be illustrated in three ranks of dropping signal, critical dropping signal and irrelevant signal.

From top description, be appreciated that, the transmission of the downlink schedule information signal of the present invention by being used for dispatching the UE that is positioned at soft handing-over zone, can reduce the waste of Node B through-put power and downlink channel code resource, and, can make single UE carry out different functions by using common schedule information by proposing to be used for the analyzing adjuncts method of UE.

Although the present invention represents with reference to its certain typical embodiment and describe, those skilled in the art is to be understood that in situation about not breaking away from by the essence of the present invention of claims regulation and scope, can carries out the variation of various forms and details.For example, in the embodiment of replacement of the present invention, this scheduling allowance value can be represented with other quantity of level that increases, can make non-clothes node carry out common scheduling neatly.
