Description

Radio communication base station device and wireless communications method

Technical field

The present invention relates to carry out radio communication base station device and the wireless communications method of multimedia broadcast/group broadcast service (Multimedia Broadcast MulticastService:MBMS).

Background technology

In UMTS (Universal Mobile Telecommunications System:UMTS), in version 6 (Release6), imported MBMS.The purpose of MBMS is following: need in the business of identical information a plurality of users, send information through the channel that uses public channel to send identical information rather than use special use to each user, thereby realize effective utilization of Radio Resource and Internet resources.

The summary of MBMS among the UMTS at first, is described.In addition, in non-patent literature 1, put down in writing its action summary, in non-patent literature 2, put down in writing the detailed action of Radio Resource control (Radio ResourceControl:RRC).

Fig. 1 is illustrated among the UMTS with point-to-multipoint (point-to-multipoint) employed channel when mode provides MBMS.In the figure, also represented relation between logic channel (Logical Channel), transmission channel (Transport Channel) and the physical channel (Physical Channel).As logic channel; Redetermination below three channels be used for MBMS, i.e. MBMS point multipoint message traffic channel (MBMSpoint-to-multipoint Traffic Channel:MTCH), MBMS point-to-multipoint control channel (MBMSpoint-to-multipoint Control Channel:MCCH) and MBMS point-to-multipoint scheduling channel (MBMS point-to-multipoint Scheduling Channel:MSCH).

Wherein, MTCH is a data channel, and it is the channel of the data of MBMS transmission.In addition, MCCH is a control channel, and it is the channel that comprises the control information that is used to provide MBMS.In addition, MSCH is a control channel, and it is the channel of the schedule information of transmission MTCH.

Secondly, as transmission channel, forward access channel (Forward Access Channel:FACH) is used to transmit three logic channels.FACH is the channel that just exists originally among the UMTS, is not to be newly defined as the channel that MBMS uses.

At last, as physical channel, Secondary Common Control Physical Channel (Secondary Common ControlPhysical Channel:S-CCPCH) is used to transmit this FACH.S-CCPCH also is the channel that just exists originally among the UMTS, is not to be newly defined as the channel that MBMS uses.

Below, the 2nd layer (Layer2) and the 3rd layer (Layer3) mainly is described.Above-mentioned MCCH at first, at length is described.MCCH is categorized as two classifications haply, i.e. crucial (Critical) and non-key (NonCritical).In addition, key is divided into three individual system, and promptly notice (Notification) is used message with message (message), radio bearer (Radio Bearer:RB) information (information) with message and the conventional information relevant with MBMS.With respect to this,, only there is counting (Counting) to use message as non-key.

Particularly, use message, have MBMS to change business information (MBMSMODIFIED SERVICES INFORMATION as notice; It is the message of the information of the existing business that changes of expression, also comprises the subsequent action to the terminal) and the non-change business information of MBMS (MBMSUNMODIFIED SERVICES INFORMATION; It is the message of the information of the business representing not change, also comprises the subsequent action to the terminal).

In addition, use message, the public point-to-multipoint RB information of MBMS (MBMSCOMMON P-T-M RB INFORMATION is arranged as RB information; Comprise setting public between the business in the RB information), MBMS current area point-to-multipoint RB information (MBMS CURRENT CELL P-T-M RBINFORMATION; Comprise the setting in this sub-district in the RB information) and MBMS neighbor cell point-to-multipoint RB information (MBMS NEIGHBOURING CELL P-T-M RB INFORMATION; Comprise the setting in the neighbor cell in the RB information).

In addition, use message, MBMS general information (MBMS GENERAL INFORMATION is arranged as the information relevant of routine with MBMS; Comprise optimized frequency (Preferred frequency), timer and the information of counter and configuration (configuration) information of MSCH etc. that MBMS uses).

On the other hand, as non-key, MBMS access information (MBMS ACCESSINFORMATION is arranged; Comprise the information relevant) with counting.

The terminal through receiving the MCCH defined like this message and set, can receive the MTCH of actual transmissions data or transmit the MSCH of the schedule information of MTCH.

Then, explain about notice and counting.It is professional that MBMS regularly or aperiodically provides, and always do not provide business.As object lesson, in business, identical program (programme content is each or every different at a distance from for several times) regularly is provided, or regularly sends stock market like mobile TV (Mobile TV).

In addition,, be defined in the lastest news of customizing messages etc., when new news has taken place, broadcast as so that professional example irregularly to be provided.For the such business of correspondence, need begin to provide user's interest professional to the terminal informing network.This action is exactly a notice.

Notice is divided into two classifications haply.The first kind is: the business that whether provides the terminal to ask is confirmed through confirming the message in the above-mentioned defined notice of MCCH in the terminal.Second type is: through MBMS indicating channel (MBMS Indicator Channel; MICH), notice needs to confirm the message in the above-mentioned defined notice of MCCH.

Like this, with regard to notice, there is the terminal to confirm the method for the message of notice with a step; And the method for the message of notice is confirmed at the terminal with two steps.

As the specific business that MBMS provided, through counting, whether decision need provide in the sub-district for aforesaid, perhaps then how to provide if need.As for whether providing, with the terminal of confirming whether to exist the specific business of request in the sub-district.

Particularly, at first, network send to the terminal be called probability factor (Probability factor) parameter as the information that is used for the business that will provide is counted.It is the parameter that the terminal of the part in the terminal of the specific business of request is responded, to avoid responding the congested of the circuit that caused because of all terminals of asking specific business.

Here, the terminal of having carried out response in the terminal of network through the specific business of identification request, can know to provide this business to its sub-district.More terminal in addition, when the response that does not come self terminal, changes the value of probability factor (factor), so that can respond.

Then, how the network decision provides professional.For example, because multicast sends identical information to a plurality of terminals,, need send with high power so consider to be positioned at the such terminal of cell edge (cell edge).Yet,, also have to send the situation that identical information is advisable to each terminal respectively at the terminal of asking specific business after a little while.Network also need be judged such situation.As object lesson, when having the terminal more than four, MBMS is provided, and when being less than four station terminals with multicast, be the action of individually sending MBMS etc.In this example,, confirm to exist the terminal more than four through counting.

Then, use the action of Fig. 2 explanation till the terminal receives MCCH.As stated, send MCCH through FACH (physical channel is S-CCPCH).Parameter as the transmission action of expression MCCH has following three kinds, promptly (Modification period) between conversion period, repeat during during (Repetition period) and the access information (Access Info period).Between conversion period be can not change MCCH critical message during, all identical in the content of the critical message of repeatedly sending during this period.But,, also can change non-critical messages even in this period.

In addition, during the repetition interval that the critical message of MCCH is repeated, be the integral multiple during the repetition between conversion period.In addition, during the access information be the interval that the non-critical messages of MCCH is repeated.

Through these parameters, can know which the terminal regularly obtain MCCH at.In addition, as far as the terminal, except these parameter, also need obtain to send the information of the FACH (physical channel is S-CCPCH) of MCCH.With system information block (System Information Block; SIB) 5 send these channel informations and the information relevant at interval as broadcast message with the transmission of MCCH.That is to say that the terminal can receive the preparation of MCCH through receiving SIB5.Explanation is in passing, for the terminal receives SIB5, needs the schedule information of SIB5, so obtain Master Information Block (Master Information Block in advance; MIB) schedule information that is comprised, this is that conventional broadcast message obtains action.

Like this, in the MBMS of UMTS version 6, redetermination a plurality of actions, become very complicated system.

Embodiment

Below, with reference to accompanying drawing execution mode of the present invention is described at length.But, in execution mode, to the additional same numeral of the structure with identical function, and the explanation of omission repetition.

(execution mode 1)

Fig. 3 is the figure of relation between MIB, MBMS SB and the MBMS SIB of expression embodiment of the present invention 1.In UMTS, with a plurality of message that are defined as MCCH with the form of broadcast message promptly with system information block (System information block; SIB) different systems are sent, but here, and are as shown in Figure 3, are defined as the SIB that MBMS uses (below, be called " MBMS SIB ").In addition, as the unit of SIB, each message among the MCCH of consideration UMTS.For example; Define a transmission and be equivalent to the SIB that MBMS has changed the such information of business information (MBMS MODIFIED SERVICESINFORMATION), define the SIB etc. that a transmission is equivalent to the information of the non-change business information of MBMS (MBMS UNMODIFIED SERVICES INFORMATION) that kind.But, as the distribution method of SIB, be not limited to above-mentioned method, also can utilize other method.

Through comprising for the MBMS of the schedule information of the SIB of MBMS with Scheduling Block (Schedulingblock (below, be called " MBMS SB ")), the MBMS SIB that is defined is like this dispatched.As schedule information; Except the defined transmission of the transmission of the broadcast message of UMTS regularly (position on the System Frame Number (System Frame Number)) with send the interval; Also possibly also need radio block (radioblock) to wait other information, but any information can be as schedule information.

Same with general SB, MBMS SB is through Master Information Block (Master Information Block; MIB) be scheduled.Through such action, in UMTS, need the MCCH of the MBMS of other functions to receive and to replace with the employed function of broadcast message.Particularly, the transmission through MBMS can be defined in during the repetition that define among the UMTS and during the access information at interval.Its employed information of transmission with general SIB is identical.

Use Fig. 4 that it is described.In the figure, MIB will send interval (repetition period) and be made as 4, and will sending regularly, (position) is made as 0.Definition among this and the UMTS is same.Under these circumstances, the remainder after superframe sequence number (Super Frame Number) is divided by 4 is 0 timing, and MIB is sent out.Here, as the schedule information of the MBMS SB that MIB stored, to send at interval (repetitionperiod) be 8 and send regularly that (position) is 2, so the remainder after the superframe sequence number is divided by 8 is 2 timing, MBMS SB is sent out.Likewise, the schedule information of the SIB that is stored based on MBMS SB, the transmission of decision SIB at interval with send regularly.

Below, use Fig. 5 that the structure of the base station apparatus 100 of embodiment of the present invention 1 is described.Scheduling unit 101 from after the MBMS SIB generation unit stated 106 obtain the data volume (data size) of MBMS SIB classifications and each MBMSSIB classification, and based on them, the schedule information of decision MBMS SIB.In addition, scheduling unit 101 from after the information of data volume etc. of the MBMS SB generation unit stated 104 MBMSSB that obtains to be generated, and based on this information, the schedule information of decision MBMS SB.The schedule information of the MBMS SIB that is determined is outputed to MBMS SB generation unit 104, and the schedule information of the MBMSSB that is determined is outputed to MIB generation unit 103.In addition, these schedule informations are outputed to transmitting element 107.

The information relevant in broadcast message Database Unit 102 store broadcast information with MIB, and the MIB relevant information of being stored outputed to MIB generation unit 103.

MIB generation unit 103 is based on generating MIB from the MBMS SB schedule information of scheduling unit 101 output with from the MIB relevant information of broadcast message Database Unit 102 outputs, and the MIB that is generated is outputed to transmitting element 107.

MBMS SB generation unit 104 generates MBMS SB based on the MBMS SIB schedule information from scheduling unit 101 outputs, and the MBMS SB that is generated is outputed to transmitting element 107.In addition, the information such as data volume with the MBMS SB that is generated output to scheduling unit 101.

MBMS Database Unit 105 is stored the business information that provides as MBMS and is used to provide this business needed set information, and these information of being stored are outputed to MBMS SIB generation unit 106.

MBMS SIB generation unit 106 generates MBMS SIB based on business information and set information from 105 outputs of MBMS Database Unit, and the MBMS SIB that is generated is outputed to transmitting element 107.In addition, classification and the data volume with the MBMS SIB that is generated outputs to scheduling unit 101.

Transmitting element 107 bases are from the schedule information of scheduling unit 101 outputs, and transmission is from the MIB of MIB generation unit 103 outputs, from the MBMS SB of MBMS SB generation unit 104 outputs and the MBMS SIB that exports from MBMS SIB generation unit 106.

Because base station apparatus 100 has such structure, so can likewise send MBMS SIB with general broadcast message.In addition; In UMTS, need to use during the identical repetition in the key message, and till receiving, all known with what kind of rank order the message of MCCH; But in aforesaid way; Can change each MBMS SIB and send frequency, also can notify the transmission timing of each MBMSSIB simultaneously, so can realize moving flexibly.

Consideration is to the employed value label of the broadcast message of also using UMTS between conversion period (Value tag).That is to say whether changed content rather than defined the interval of not changing such between conversion period, have or not change thereby can in the terminal, detect through being worth the label notice.

In addition, this value label does not apply to each all MBMS SIB respectively, considers to apply to upgrade simultaneously relevant MBMS SIB yet.Particularly; Owing to will be thought of as one group with the relevant information of notice; So following method is arranged: be equivalent among the SIB of SIB and the information that transmission is equivalent to MBMS UNMODIFIEDSERVICES INFORMATION of information of MBMS MODIFIED SERVICESINFORMATION in transmission, likewise increase and be worth label.In addition,, be equivalent to be defined as among the UMTS among the SIB of information of crucial message, also consider to be worth the method that label fully likewise increases in transmission as extreme utilization.

In addition, this value label also can have the scope of sending the different value of the value label of usefulness with other broadcast message.Particularly, when sending broadcast message, in UMTS, prepared the multiple labels such as value label of predetermined configurations (Predefined configuration) with the information of the value label of the information that is worth label, cell-level and PLMN level.Same therewith, considered that setting MBMS SIB is with being worth label.

Like this; According to execution mode 1, generate the MBMS SIB of MCCH as broadcast message, comprise the schedule information of MBMS SIB and generate MBMS SB; Comprise the schedule information of MBMS SB and generate MIB; These information that generated are sent to the terminal, thereby can likewise send MBMS SIB, so can cut down expense with general broadcast message.

In addition, in this execution mode, explained that the use value label replaced between conversion period to detect the method for change, but also can use the notion between conversion period.Particularly, the packets of information between conversion period is contained in MBMS SB or MIB and notifies to the terminal.At this moment, the point between conversion period is identical with UMTS to start with, and the value of the Mod that also can obtain divided by specific value for system frame number is 0 point, also can be with MBMS SB etc. as basic point.In addition, also consideration and UMTS likewise are made as the interval between conversion period the transmission integral multiple at interval of MBMS SIB, also can it be defined as the transmission integral multiple at interval of MBMS SB.

In addition, in this execution mode, defined MBMS SB, but, can consider that also the content of MBMS SB all is included among the MIB as utilization.Under these circumstances, directly carry out the scheduling of MBMS SIB from MIB.

In addition, also can use general SB, be not only with the SIB that comprises other and comprise the SIB relevant with MBMS as MBMS SB.

In LTE, the transmission of broadcast message has been defined part of sending with fixing resource and the part of sending with variable resource.Here, fixing resource is meant that the time of the 1.25MHz frequency band internal fixation of central authorities shown in Figure 6 regularly.In addition, variable resource is the 10MHz frequency band of central authorities.At this moment, for how sending MIB, MBMS SB and MBMS SIB, consider several patterns (pattern).

Need send with fixing resource MIB, so that the terminal only can receive fixing information.On the other hand, consider to send MBMS SB and MBMS SIB with variable resource.Therefore, as shown in Figure 6, consider that only MIB uses fixing resource to send, use variable resource to send MBMS SB and MBMS SIB.Yet, can as stated MBMS SB be included among the MIB, also can send with fixing resource.In addition, even also can use fixing resource to send to MBMS SIB.

In addition, consider a plurality of frequency bands are used for MBMS.Fig. 7 representes this situation.Here, Fig. 7 A representes to be made up of each frequency band of a plurality of frequency bands the example of the sub-district of same area, and Fig. 7 B representes to be made up of a plurality of frequency bands the example of the sub-district of zones of different.

At first, consider the example shown in Fig. 7 A.At this moment, as the sending method of MBMS SB, shown in Fig. 8 A to Fig. 8 D, consider four kinds of methods.Fig. 8 A representes with a plurality of frequency bands MBMS to be provided, and sends the situation of information of the MBMS SB of each frequency band with each frequency band.Fig. 8 B representes with a plurality of frequency bands MBMS to be provided, and sends the situation of information of MBMS SB of information and other frequency band of the MBMS SB of each frequency band with each frequency band.Fig. 8 C representes with specific frequency band MBMS to be provided, and sends the situation of information of the MBMS SB of the frequency band that MBMS is provided with each frequency band.Fig. 8 D representes following situation: the frequency band with specific provides MBMS, is providing the frequency band of MBMS that the information of MBMS SB is provided, and frequency band in addition only sends the information of the frequency band that MBMS is being provided.This execution mode can be applicable to any method shown in Fig. 8 A to Fig. 8 D.

Secondly, consider the example shown in Fig. 7 B.At this moment, as the sending method of MBMS SB, shown in Fig. 9 A to Fig. 9 D, consider four kinds of methods.In addition, Fig. 9 A to Fig. 9 D becomes the action identical respectively with the action of Fig. 8 A to Fig. 8 D respectively.But as difference, the zone of sub-district is different to each frequency band, representes the situation of the same cells of other frequency bands so consider a plurality of sub-districts, and on the contrary, the situation of a plurality of sub-districts of other frequency bands is represented in a sub-district.That is to say, the zone that MBMS is provided with the regional different of general business are provided, so there are a plurality of sub-districts to represent the situation of a sub-district (Fig. 9 B and Fig. 9 C).

In addition, consider in LTE, to be provided with the special-purpose frequency band of MBMS.These frequency bands are called MBMS dedicated cell (MBMS dedicated cell) and MBMS special layer (MBMS dedicatedlayer) etc. in LTE.In these sub-districts, identical with general sub-district, might not send MIB etc.At this moment, shown in Figure 10 A and Figure 10 B, can carry out two replies.Figure 10 A representes following situation: a plurality of frequency bands to comprise the MBMS dedicated cell provide MBMS, are sent the information of MBMS SB of information and MBMS dedicated cell of the MBMS SB of each frequency band by the sub-district except the MBMS dedicated cell.Figure 10 B representes following situation: only with the MBMS dedicated cell MBMS is provided, is sent the information of the MBMS SB of MBMS dedicated cell by the sub-district except the MBMS dedicated cell.

Through these actions, the utilization that also can tackle the utilization of having used different frequency bands and use the MBMS dedicated cell.

In addition, consider when a plurality of frequency bands send MBMS, between frequency, to make the schedule information of MBMS SB common.That is to say, will be used for representing this frequency band MBMS SB the position and the information that is contained in MIB is made as in all frequency bands identical.Thus, also can cut down the information that is used to represent MBMS SB.

(execution mode 2)

Among the MBMS in LTE (Long Term Evolution), discussing SFN (SingleFrequency Network) operation.SFN operation is meant, through from a plurality of base stations in same frequency band and identical timed sending identical information, the function that signal is synthetic on wireless.Through this SFN operation, can significantly improve the quality of reception that is positioned at the such terminal of cell edge.

Yet this operation is a prerequisite with the situation that is suitable for identical information in a plurality of base stations, does not send such information so only be suitable in specific base stations.Here, such situation is called non-SFN operation.

As stated, SFN operation be characterized as the synthetic of signal between the base station, in order to realize this characteristic, comparing with the communication in the general sub-district needs to use long Cyclic Prefix (Cyclic Prefix; CP).This be because, synthetic from a plurality of signal of base station need than synthetic from signal of base station longer during.Thus, carrying out sending data with different forms under SFN situation of operating and the situation of carrying out non-SFN operation.

In LTE, prepare multicast channel (Multicast; MCH) conduct is operated corresponding transmission channel with SFN, prepares DSCH Downlink Shared Channel (Downlink Shared Channel; DL-SCH) use transmission channel as general transmission.Therefore, we can say through MCH transmission SFN operation and use information, transmit non-SFN operation through DL-SCH and use information.

As stated, form is different between MCH and DL-SCH, so can't need send with different timing with identical timed sending in same frequency band.Therefore, send the MBMS data of SFN operation and the MBMS data of non-SFN operation with different timing.This different timing is sent and is not only gone for data itself, also is applicable to the control information (MCCH) of these data.That is to say, the MBMS data of carrying out the SFN operation are carried out the SFN operation, the MBMS data of non-SFN operation are carried out non-SFN operation.

Here, Figure 11 representes the configuration example of subframe.Shown in figure 11, in MBMS SB, respectively the SFN operation is dispatched with SIB with SIB and non-SFN operation.This be because, even a SIB also need send SFN operation with different timing and operate with SIB and non-SFN and use SIB.Through such scheduling, also can SFN operation and non-SFN operation be provided to MCCH.

Below, use Figure 12 that the structure of the base station apparatus 200 of embodiment of the present invention 2 is described.The corresponding scheduling unit 201 of SFN from after the SFN operation stated obtain MBMS SIB classification and its data volume of SFN operation usefulness with MBMS SIB generation unit 203.In addition, from after the non-SFN operation stated obtain MBMS SIB classification and its data volume of non-SFN operation usefulness with MBMSSIB generation unit 204.The corresponding scheduling unit 201 of SFN determines the schedule information of MBMS SIB based on these information that obtained.The schedule information of the MBMS SIB that is determined is outputed to MBMS SB generation unit 202.At this moment, the corresponding scheduling unit 201 of SFN is set the SFN operation and is used MBMS SIB, so that it can carry out the timed sending that SFN operates, and sets non-SFN operation and uses MBMS SIB, so that it is in the timed sending of not carrying out the SFN operation.In addition, suppose that the corresponding scheduling unit 201 of SFN has the information that whether can carry out the SFN operation.

The corresponding MBMS SB of SFN generation unit 202 uses from the schedule information of the MBMS SIB of corresponding scheduling unit 201 outputs of SFN; Generation is divided into the SFN operation and operates the MBMS SB with schedule information with schedule information and non-SFN, and the MBMS SB that is generated is outputed to transmitting element 107.In addition, the information such as data volume with the MBMS SB that is generated output to the corresponding scheduling unit 201 of SFN.

The SFN operation, generates the SFN operation and uses MBMS SIB based on business information and set information from 105 outputs of MBMS Database Unit with MBMS SIB generation unit 203, and the SFN operation that is generated is outputed to transmitting element 107 with MBMS SIB.The classification and the data volume of in addition, the SFN that is generated being operated with MBMS SIB output to the corresponding scheduling unit 201 of SFN.

Non-SFN operation, generates non-SFN operation and uses MBMS SIB based on business information and set information from 105 outputs of MBMS Database Unit with MBMS SIB generation unit 204, and the non-SFN operation that is generated is outputed to transmitting element 107 with MBMS SIB.The classification and the data volume of in addition, the non-SFN that is generated being operated with MBMS SIB output to the corresponding scheduling unit 201 of SFN.

Like this,, will dispatch respectively with the MBMS SIB of MBMS data and for the MBMS SIB of non-SFN operation for the SFN operation with the MBMS data according to execution mode 2, thus the control information that can send the MBMS corresponding with the SFN operation.

In addition; In this execution mode; Explained that a MBMS SB comprises for the SFN operation with the schedule information of SIB and for schedule information both situation of non-SFN operation with SIB, operated to operate and use MBMS SB with MBMS SB and non-SFN but also can define SFN as MBMS SB.In addition, be not under the situation of the special-purpose SB of the such MBMS of MBMS SB at SB for routine, also can be defined as the SIB that carries out the SFN operation and use SB with SB and the SIB that carries out non-SFN operation.

(execution mode 3)

In execution mode 2; Explained the SFN operation has been carried out in the control information (MCCH) of the MBMS data of SFN operation usefulness; Non-SFN is operated the control information (MCCH) of the MBMS data of usefulness and carry out the situation of non-SFN operation, but consider in the way of MBMS controlled step, still to carry out the situation that non-SFN operation changes carrying out the SFN operation.

Particularly, the quantity at the terminal of the MBMS data that the imagination request is specific is few, and these terminals concentrate on the situation of particular cell.Under these circumstances; Operate with carrying out SFN, compare, not as carrying out non-SFN operation and send MBMS data in all sub-districts of a plurality of sub-districts that comprise the terminal that does not receive; Only send the MBMS data in the sub-district at the terminal that has the specific MBMS data of request, its efficient is higher.Figure 13 representes this situation.

Same information is sent with identical timing and same frequency for carrying out the unit of SFN operation in all sub-districts in this scope in SFN zone shown in Figure 13.Thus, as long as in this SFN zone,, also on wireless, carry out synthesizing between the base station even be positioned at cell edge.In the figure, expression asks the terminal of specific MBMS data to exist only in the situation of three sub-districts.Under these circumstances, other sub-districts beyond in above-mentioned three sub-districts are sent the MBMS data and wastes, so consider only in the transmission of above-mentioned three sub-districts.

Yet,, need to use at the original counting in position at the terminal of these MBMS data of request etc. in order only to detect the such situation in terminal that in three sub-districts, has the specific MBMS data of request.Can make the indication of this counting general between the sub-district, so can be suitable for the SFN operation.

Like this, consider controlled step, finally become the action of non-SFN operation by SFN operation beginning MBMS.Figure 14 representes the example of such MBMS controlled step.In Figure 14 A to Figure 14 H, all be identical MBMS controlled step, but difference is that each message is carried out the SFN operation still carries out non-SFN operation.Below, represent concrete MBMS controlled step.

In ST301, with beginning to provide professional advisory, in ST302, will comprise what kind of professional notification of information of expression beginning from the base station and send to the terminal to the terminal from the base station.

In ST303, through sending to the information that the terminal is provided for counting, in ST304, through sending to the result that notifications count is come in the base station from the terminal with counting response (Counting response) from the base station with access information (Access Info).

In ST305, notify the RB information of sending MTCH through RB information (RB Info) being sent to the terminal from the base station, in ST306, through MTCH, reality sends to the terminal with data from the base station.

Consideration is sent message through MCH or DL-SCH in the process of such MBMS controlled step.For example; In Figure 14 A, the MBMS controlled step that expression is sent out when sending all message through MCH, and in Figure 14 C; MBMS controlled step below the expression: the message of sending ST301 to ST303 through MCH; Based on the result of counting response, after non-SFN operation is carried out in decision, through the DL-SCH transmission ST305 of non-SFN operation and the message of ST306.

In addition; In Figure 14 G; Opposite with the MBMS controlled step shown in Figure 14 C, the MBMS controlled step below the expression: through the message of DL-SCH transmission ST301 to ST303, based on the result of counting response; After non-SFN operation is carried out in decision, through the MCH transmission ST305 of SFN operation and the message of ST306.

Yet, when between SFN operation and non-SFN operation, switching like this, have following problem.That is to say,, need receive both sides' message at the terminal to each is professional when still switching through non-each business of SFN operation utilization through SFN operation utilization.Particularly, under the situation shown in Figure 14 C, switch to the DL-SCH of non-SFN operation from the RB information of ST305.Therefore, the RB information that need discern ST305 at the terminal is non-SFN operation usefulness, and needs corresponding such switching.

In Figure 14, represented all patterns, but when the result based on counting judged whether to carry out the SFN operation, the MBMS controlled step that produces the switching between SFN operation and the non-SFN operation was represented to be among Figure 14 C and Figure 14 G.Therefore, shown in figure 15, be the count results (Counting result) of ST351 with the result's of notifications count message definition.Here, count results is through being that MCH or DL-SCH send with hereto the identical channel of MBMS controlled step.Under the situation shown in Figure 15 A, send the message of ST301 to ST303 through MCH.Therefore, also send the count results of ST351, and decision is a message of notifying ST305 and ST306 with MCH or with DL-SCH according to count results through MCH.Under the situation shown in Figure 15 B, send the message of ST301 to ST303 through DL-SCH.Therefore, also send the count results of ST351, and decision is with MCH or the message of DL-SCH notice ST305 and ST306 according to count results through DL-SCH.

Figure 16 is the block diagram of structure of the base station 400 of expression embodiment of the present invention 3.The difference of Figure 16 and Figure 12 is, has appended receiving element 401 and has changed to MBMS Database Unit 403 with counting processing unit 402 and with MBMS Database Unit 105.

Receiving element 401 receives the signal that sends from a plurality of terminals, and the signal that receives is outputed to counting processing unit 402.

Counting processing unit 402 is counted based on the signal of exporting from receiving element 401, and the result that will count outputs to MBMS Database Unit 403.

Based on result, judge whether the SFN operation is applicable to the control information to specific MBMS data as the MBMS Database Unit 403 of message generation unit from the counting of counting processing unit 402 outputs.MBMS Database Unit 403 as count results, outputs to this result of determination the SFN operation and operates with MBMS SIB generation unit 204 with MBMS SIB generation unit 203 or non-SFN.

Here, based on the MBMS controlled step shown in Figure 15 A, the action of base station shown in Figure 16 400 is described.At first, send the notice and the access information of ST302 of ST301 through MCH, output to SFN from MBMS Database Unit 403 and operate with MBMSSIB generation unit 203 so be used to generate the information of corresponding SIB.

SFN operation with MBMS SIB generation unit 203 in, use from the information of MBMS Database Unit 403 outputs and generate SIB, the information of the SIB that expression is generated outputs to SFN correspondence scheduling unit 201, and SIB itself is outputed to transmitting element 107.The transmission processing and the execution mode 2 of the notice of ST301 after this and the access information of ST302 are same, so omit its detailed explanation.

In receiving element 401, receive the counting response of ST304, and received counting response is outputed to counting processing unit 402.In counting processing unit 402, based on counting response, judge whether this business is provided in this sub-district from receiving element 401 outputs, when providing, judge whether carry out the SFN operation.Result of determination is outputed to MBMS Database Unit 403.

In MBMS Database Unit 403,, judge and whether need send the RB information of ST305 and the MTCH of ST306 based on result of determination from 402 outputs of counting processing unit.When needs send, judge whether carry out the SFN operation.

Then, with the count results of this result, output to the SFN operation and operate with MBMS SIB generation unit 204 with MBMS SIB generation unit 203 or non-SFN as ST351.But; When sending the access information of ST303 through the SFN operation; Count results is outputed to the SFN operation with MBMS SIB generation unit 203, and when sending the access information of ST303 through non-SFN operation, count results is outputed to non-SFN operation with MBMS SIB generation unit 204.

In addition; Carry out SFN when operation being judged as; The content of the RB information of ST303 is outputed to the SFN operation with MBMS SIB generation unit 203, be judged as when carrying out non-SFN operation, the content of the RB information of ST303 is outputed to non-SFN operate with MBMS SIB generation unit 204.In Figure 14 C, be judged as and carry out non-SFN operation, so the content of RB information is outputed to non-SFN operation with MBMS SIB generation unit 204.As action after this, same with the action of existing action and execution mode 2.

Figure 17 is the flow chart of the action of the above-mentioned base station 400 of expression.In the figure, in ST501, send notice, in ST502, the parameter that decision is set by access information.Particularly, when sending access information, determine to the parameter that further increases the terminal of beaming back response etc.

In ST503, send access information, confirm that its result promptly responds.In ST504, whether whether the result who judges counting for enough sending with judgement and whether carrying out SFN and operate.Being under the enough situation, get into ST505, and under not enough situation, return ST502.

In ST505, whether according to the result of counting, judging provides professional in this sub-district, being judged to be when providing, gets into ST506, and is being judged to be when not carrying out sending, and gets into ST511, end process.In ST506, judge whether to carry out SFN operation, being judged as when carrying out, get into ST507, and be judged as when not carrying out, get into ST509.

In ST507, utilize count results to give the terminal through the professional advisory of SFN operation beginning, in ST508, be controlled to be through the SFN operation and send after this MBMS control information and data.

In ST509, utilize count results to give the terminal through the professional advisory of non-SFN operation beginning, in ST510, be controlled to be through non-SFN operation and send after this MBMS control information and data.

Through such action, can carry out the switching between SFN operation and the non-SFN operation.In addition, be for the action of a business rather than the action of MBMS integral body here.

Figure 18 representes the block diagram of structure at the terminal 600 of embodiment of the present invention 3.In Figure 18; Broadcast message receiving element 601 receives the broadcast message of 400 transmissions from the base station; Based on from after the MIB processing unit 602, MBMS SB processing unit 603 stated and the information of MBMS control unit 605 outputs, the MIB that broadcast message comprised that receives is outputed to MIB processing unit 602, MBMS SB is outputed to MBMS SB processing unit 603 and MBMS SIB is outputed to MBMS SIB processing unit 604.In addition,,, comprise MIB, MBMS SB and MBMS SIB here as broadcast message.

MIB processing unit 602 is based on the MIB from 601 outputs of broadcast message receiving element; Obtain the schedule information of MBMS SB; The schedule information of the MBMS SB that is obtained is notified to MBMS control unit 605, simultaneously the schedule information of MBMS SB is set to broadcast message receiving element 601.

MBMS SB processing unit 603 is based on the MBMSSB from 601 outputs of broadcast message receiving element; Obtain the schedule information of MBMS SIB; The schedule information of the MBMS SIB that is obtained is notified to MBMS control unit 605, simultaneously the schedule information of MBMS SIB is set to broadcast message receiving element 601.

604 couples of MBMS SIB from 601 outputs of broadcast message receiving element of MBMS SIB processing unit handle, and the MBMS SIB after handling is notified to MBMS control unit 605.

MBMS control unit 605 carries out the control of MBMS based on the information from MIB processing unit 602, MBMS

SB processing unit

603 and 604 outputs of MBMS SIB processing unit.Based on this control result, MBMS SB receives and MBMS SIB reception to 601 indications carrying out of broadcast message receiving element, and the MBMS Data Receiving is carried out in 607 indications to MBMS Data Receiving unit.In addition, when beaming back response, generate and to respond, and the response that is generated is outputed to MBMS related news transmitting element 606 according to needs such as counting grade.

MBMS related news transmitting element 606 will send to base station 400 with upward signal from the MBMS such as response of the counting of MBMS control unit 605 output.

MBMS Data Receiving unit 607 receives the MBMS data of 400 transmissions from the base station according to the indication of the MBMS Data Receiving of exporting from MBMS control unit 605.

Through such structure, the control information that terminal 600 can receive MBMS with broadcast message receiving element 601 is that MBMS SIB handles as broadcast message by 604 pairs of MBMS control informations of MBMS SIB processing unit.

Here, as MBMS data being carried out the different example of SFN operation with non-SFN operation respectively, considering only to make counting to handle can be that unit carries out with the sub-district.That is to say that counting is treated to accepting the response of self terminal and handle in each sub-district, thus sometimes in certain sub-district through counting the existence of sense terminals immediately, perhaps also be difficult to the existence of sense terminals sometimes through counting in certain sub-district.Thus, consider processing is counted in each sub-district.In counting is handled, need the adjustment probability factor, so that response is beamed back at the terminal 600 of right quantity.Consider to handle condition of different between the base station.Figure 19 representes the action of this moment.

Figure 19 A representes always to transmit through MCH the situation of the message that is used to count.With respect to this, in Figure 19 B, become DL-SCH from MCH on the way.Its situation in the SFN zone, all beginning at first but on the way need changing with same settings.For the such action of correspondence, consider that (the next access information of expression sends through MCH or sends through DL-SCH in the message of the access information of 1≤n≤N-1) at ST702-n.

In Figure 19 C, send access information through DL-SCH from the beginning.At this moment, need represent to send access information through the notice of ST301 with DL-SCH.Also can realize this action through structure shown in Figure 16.Particularly; Based on result, append whether send the information whether access information (ST702-1 to ST702-N) still carries out the information conduct message (notice (ST701) is to access information (ST702)) before this of SFN operation in the MBMS Database Unit 403 from counting processing unit 402.

Under environment shown in figure 13, need such action.That is to say, in general SFN operation, judge whether that at first all sub-districts in the SFN zone are sent,, judge whether to provide in each sub-district professional being judged as when not carrying out the SFN operation.At this moment, consider that the probability of use factor also sends, said probability factor is different between the sub-district of the existence that early detects relevant terminal and slower detected sub-district.Thus, can control transmission in the sub-district that early detects from the terminal that need not.

Consideration also needs such action when the SFN operation of a carrying out part shown in figure 20.At this moment, consider not only to carry out the action of Figure 13, also the result according to counting sends the neighbor cell that detects the sub-district that has the terminal, carries out the SFN operation of a part.At this moment, consider to use in the sub-district that detects the terminal, its neighbor cell is different with the probability factor of the sub-district of sense terminals not.

Like this; According to execution mode 3; When in the way of MBMS controlled step, between SFN operation and non-SFN operation, switching; The packets of information that expression is switched is contained in notice and gives in the count results at terminal, thereby need not to send message that is suitable for the SFN operation and the message that is suitable for non-SFN operation both, can carry out the MBMS controlled step efficiently.

In addition; In this execution mode, Figure 13, Figure 14 and Figure 17 represent the example of timing for finishing to return behind the access information (ST303-N) that counting response returns, but according to the result of the counting step at terminal; Sometimes between ST303-1 to ST303-N, return, return response with any timing and get final product.

In addition, like Figure 13, shown in 14 and 17, expression notice is that message and RB message are the situation of a message in this execution mode, but UMTS that also can be shown in example in the past is such, and (or SIB) uses with a plurality of message.

In addition, the action at terminal shown in Figure 180 is also set up in receiving from the terminal of the signal of base station corresponding with

execution mode

1 and 2.

(execution mode 4)

In UMTS, defined MBMS Indication Channel (MICH), can indicate the reception of MCCH thus to the terminal.More detailed, shown in figure 21, initial between next conversion period, MICH is the action that impels notification message (MBMS MODIFIED SERVICESINFORMATION and the MBMS UNMODIFIED SERVICES INFORMATION) that kind that receives MCCH.In addition,,, use the ID that has gathered a plurality of business that the terminal is indicated here as MICH.Therefore, as the terminal, be not to notify the terminal in fact to want the business that receives sometimes.Therefore, the content of terminal check notice finally judges whether to exist own the business that will receive.

The action of this MICH becomes and Page Indication Channel (the Paging Indicator Channel that in UMTS, carries out the notice of general calling; PICH) notion that is similar to.Therefore, in LTE, also be considered the notion approximate with PICH.Figure 22 representes the notion of the PICH among the LTE.As shown in the drawing, send PICH through the L1/L2 control channel, how this LI/L2 control channel is sent out if being illustrated in which type of information of data division.The terminal includes paging information through obtaining this PICH, can identifying.Identical as if MICH is thought of as with this action, then can consider to send MICH, in the such action of data division transmission notice through the L1/L2 control channel.

Yet, shown in enforcement mode 2, be thought of as the notice that has the notice of carrying out the SFN operation and carry out non-SFN operation, need respectively with different timed sending.Therefore,, also need prepare two kinds,, also need wait for two MICH the terminal as far as MICH.Its result, as far as the terminal, the time that receives is elongated, so increase power consumption.In addition, the notion between conversion period also is incorporated under the situation among the LTE, might be during using different repetitions between SFN operation and the non-SFN operation.Therefore, as far as MICH, also need two kinds this moment.

Therefore, can consider for MBMS SB definition MICH rather than for notice definition MICH.Figure 23 representes its sketch map.Shown in figure 23, through with the subframe identical (perhaps time slot (slot) and Transmission Time Interval (Transmission Time Interval with sending MBMS SB; TTI)) send MICH.Thus, the terminal need not to wait for a plurality of notices, and as long as confirm the L1/L2 control channel (control channel) of the TTI that MBMS SB is sent out.In addition, shown in figure 23, might in the subframe (perhaps slot and TTI) of sending MCH, there be the L1/L2 control information.This is because MBMS is the classification that is sent out with resource fixing on certain degree, rather than the classification of on time or frequency, freely dispatching.For MBMS SB definition MICH, also effective to such situation.

Figure 24 is the block diagram of structure of the base station 800 of expression embodiment of the present invention 4.The difference of Figure 24 and Figure 12 is; Appended MICH generation unit 802 and sent regularly adjustment unit 804 with MICH; MBMS Database Unit 105 is changed to MBMS Database Unit 801, deleted transmitting element 107, and appended L3/L2 transmitting element 803 and L1 transmitting element 805.

MBMS Database Unit 801 outputs to the SFN operation with business information and set information and operates with MBMS SIB generation unit 204 with non-SFN with MBMS SIB generation unit 203, and the information that will be used to generate MICH outputs to MICH generation unit 802.

MICH generation unit 802 generates MICH based on the information from 801 outputs of MBMS Database Unit, and the MICH that is generated is outputed to regularly adjustment unit 804 of MICH transmission.

L3/L2 transmitting element 803 will from the MIB of MIB generation unit 103 output, from the MBMS SB of the corresponding MBMS SB of SFN generation unit 202 outputs and from the SFN operation with the SFN operation of MBMS SIB generation unit 203 outputs with MBMS SIB from the 3rd layer and the 2nd level not (level) send to lower floor, output to MICH transmission timing adjustment unit 804 simultaneously.

MICH sends regularly adjustment unit 804 based on the schedule information from corresponding scheduling unit 201 outputs of SFN; The transmission of adjustment MICH regularly so that output to L1 transmitting element 805 from the L1/L2 control channel of the subframe of the transmission MBMS SB of L3/L2 transmitting element 803 outputs, sending from the MICH of MICH generation unit 802 outputs and the MICH that will adjust after sending timing.

L1 transmitting element 805 sends the regularly MICH of adjustment unit 804 outputs in 1 grade of transmission of layer from MICH based on the schedule information from corresponding scheduling unit 201 outputs of SFN.

The action of base station shown in Figure 24 800 is described here.MBMS Database Unit 801 is when beginning new business, and the information that this is professional is notified to MICH generation unit 802.

MICH generation unit 802 generates the content of sending as MICH based on the information that obtains from MBMS Database Unit 801.Particularly, generate the indication information of the business that expression newly begins.This information is outputed to MICH and is sent regularly adjustment unit 804.

Send regularly in the adjustment unit 804 at MICH, adjust so that MBMS SB and MICH with identical timed sending.At this moment, not only merely with identical timed sending, the timing that also need consider to be used to provide the control information of new business to be sent out.As implement shown in the mode 1, it has and identical functions between the conversion period in UMTS, so can consider the recovery value label or be suitable between conversion period.Under the former situation, need from through send for the information of new business upgraded for the value label of control information, original M BMS SB sends MICH.Figure 25 representes its action example.

Like this, the timing that is updated from the value label begins the transmission of MICH.In addition, the example of value label of the control information of relevant SFN operation is only upgraded in current expression.When following the renewal that is worth label etc. at the terminal, the actions such as a side of this value label also can have only been confirmed to upgrade.In addition, when using between conversion period itself, need send MICH by original M BMS SB between conversion period.At this moment, as stated, need consideration SFN operation to manipulate the situation between different conversion periods with non-SFN.Therefore, consider under the situation of SFN operation, the MBMS SB of the beginning between the conversion period of SFN operation is sent MICH, and under the situation of non-SFN operation, the MBMS SB of the beginning between the conversion period of non-SFN operation is sent MICH.In addition,, considered that the MBMS SB in content to notice is between the conversion period that changed sends MICH here, MBMS SB upgraded earlier under such situation between conversion period before this, between conversion period before this in transmission for the MICH of MBMS SB.

Through above action, the terminal can utilize a MICH to wait for by the MBMS data of SFN operation with by the MBMS data of non-SFN operation.

Figure 26 representes the block diagram of structure at the terminal 900 of embodiment of the present invention 4.The difference of Figure 26 and Figure 18 is, has appended MICH receiving element 901.

MICH receiving element 901 receives MICH based on the schedule information of the MBMS SB that exports from MIB processing unit 602.The MICH that is received is outputed to MBMS control unit 605 and broadcast message receiving element 601.That is to say, when receiving MBMS SB,, carry out MBMS SB by broadcast message receiving element 601 and receive processing based on information from MICH receiving element 901 based on MICH.In addition, when receiving the notice of MBMS SIB,, carry out MBMS SIB by broadcast message receiving element 601 and receive processing based on information from MBMS control unit 605 based on this MICH.

Through such structure, can carry out the reception of MBMS SB or MBMS SIB accordingly with MICH.

Like this; According to execution mode 4; Through sending MBMS SB and MICH with identical transmission unit such as identical TTI or slot; The terminal can utilize a MICH etc. pending both of MBMS data and the MBMS data of having carried out non-SFN operation of SFN operation, can shorten the stand-by period at terminal, thereby can lower power consumption.

In addition, in this execution mode, expression is sent MICH through the L1/L2 control channel of the subframe (or slot and TTI) of MBMS transmission SB.As its expansion, can carry out the transmission of MICH before from several sub-frame (or slot and TTI) of the timing of sending MBMS SB.Through such action, can avoid taking defeat of MICH etc.Figure 27 representes its action example.

In addition, in this execution mode,, the information that is used to represent business is shown as the content that MICH comprised.In addition, consider to comprise to carrying out information that the SFN operation still carries out non-SFN operation for its professional notice as information.At this moment, the terminal knows that it still is that the SFN that confirms non-SFN operation is advisable that the notice of confirming the SFN operation is advisable, so can only confirm a side notice.In addition, as implied above, in UMTS, send the information of expression bouquet rather than send the professional whole content of expression through MICH through MICH.When in LTE, using this notion, can the crowd be divided into through the SFN operation and notify and notify through non-SFN operation.

Have, in above-mentioned each execution mode, constituting situation of the present invention with hardware is that example is illustrated again, but the present invention also can realize with software.

In addition, the LSI that each functional block that is used for the explanation of above-mentioned each execution mode typically is used as integrated circuit realizes.These pieces both can be integrated into a chip individually, also can one of which partly or entirely be integrated into a chip.Though be called LSI here,, also can be called IC, system LSI, super large LSI (Super LSI) or especially big LSI (Ultra LSI) according to the difference of integrated level.

In addition, the technology of integrated circuit is not limited only to LSI, also can use special circuit or general processor to realize.Also can LSI make the FPGA that the back utilization can programme (Field ProgrammableGate Array: field programmable gate array), the connection of the circuit unit that perhaps reconfigurable LSI is inner and the reconfigurable processor of setting.

Moreover, if along with semi-conductive technological progress or other technological derivation, the technology of the integrated circuit of alternative LSI has appearred, this technology also capable of using realizes the integrated of functional block certainly.Also exist the possibility that is suitable for biotechnology etc.

The spy of application on October 30th, 2006 is willing to that the spy of 2006-294728 and application on December 21st, 2006 is willing to that the disclosed content of specification, accompanying drawing and specification digest that comprises in the japanese publication of 2006-344925 all is incorporated in the application.
