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 universal mobile telecommunications system (Universal Mobile Telecommunications System:UMTS), in version 6 (Release6), imported MBMS.The purpose of MBMS is as follows: need in the business of identical information a plurality of users, send information by 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 three following 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 for comprising the channel of 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.At first, explain above-mentioned MCCH.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 with message (message), radio bearer (Radio Bearer:RB) information (information) the information message relevant with MBMS with message and routine.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 terminal) and the non-change business information of MBMS (MBMSUNMODIFIED SERVICES INFORMATION; It is a message of representing the information of the business that do not change, also comprises the subsequent action to terminal).

In addition, as RB information message, the public point-to-multipoint RB information of MBMS (MBMSCOMMON P-T-M RB INFORMATION is arranged; 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, as the information message relevant of routine, MBMS general information (MBMS GENERAL INFORMATION is arranged 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.

Terminal by receiving the MCCH defined like this message and set, can receive the MSCH of the schedule information of the MTCH of actual transmissions data or transmission MTCH.

Then, illustrate 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 different every for several times) regularly is provided, or regularly sends stock market as 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 the user's interest business to the terminal informing network.This action is exactly a notice.

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

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

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

Particularly, at first, network is called the parameter of probability factor (Probability factor) as the information that is used for the business that will provide is counted to the terminal transmission.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 by the specific business of identification request, needing as can be known provides 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 in the terminal of asking specific business after a little while.Network also needs such situation is judged.As object lesson, when having the terminal more than four, provide MBMS, and when being less than four station terminals with multicast, be the action that individually sends MBMS etc.In this example,, confirm to exist the terminal more than four by counting.

Then, use the action of Fig. 2 explanation till terminal receives MCCH.As mentioned above, send MCCH by 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 that repeatedly sends 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 repeating between conversion period.In addition, during the access information be the interval that the non-critical messages of MCCH is repeated.

By these parameters, which terminal regularly obtain MCCH at as can be known.In addition, for terminal, except these parameters, also need to 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 terminal can receive the preparation of MCCH by receiving SIB5.Explanation is in passing, for 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, explain embodiments of the present invention with reference to accompanying drawing.But in execution mode, to the additional same numeral of the structure with identical function, and the repetitive description thereof will be omitted.

(execution mode 1)

Fig. 3 is MIB, the MBMS SB of expression embodiment of the present invention 1 and the figure of the relation between the MBMS SIB.In UMTS, with a plurality of message of being defined as MCCH with the form of broadcast message promptly with system information block (System information block; SIB) different systems send, but here, 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 a transmission and be equivalent to SIB of the such information of the non-change business information of MBMS (MBMS UNMODIFIED SERVICES INFORMATION) etc.But, as the distribution method of SIB, be not limited to above-mentioned method, also can utilize other method.

By 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)) and send the interval, also may also need radio block (radioblock) to wait other information, but any information can be as schedule information.

Same with general SB, MBMS SB is by Master Information Block (Master Information Block; MIB) be scheduled.By 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 by MBMS at interval, can be defined in during the repetition that define among the UMTS with access information during.Its employed information of transmission with general SIB is identical.

Use Fig. 4 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.Similarly, the schedule information of the SIB that is stored based on MBMS SB, the transmission of decision SIB is at interval and 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 obtains the data volume (data size) of MBMS SIB classification and each MBMSSIB classification from MBMS SIB generation unit 106 described later, and based on them, determines the schedule information of MBMS SIB.In addition, scheduling unit 101 obtains the information of the data volume of the MBMSSB that generated etc. from MBMS SB generation unit described later 104, and based on this information, the schedule information of decision MBMS SB.The schedule information of the MBMS SIB that is determined is output to MBMS SB generation unit 104, and the schedule information of the MBMSSB that is determined is output to MIB generation unit 103.In addition, these schedule informations are output 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 generated output to scheduling unit 101.

MBMS Database Unit 105 business information that provides as MBMS is provided 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 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 similarly 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 know the message of the MCCH that sorted in what order, but in aforesaid way, can change the transmission frequency to each MBMS SIB, 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 such interval of not changing between conversion period, have or not change thereby can in terminal, detect by 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, because the information relevant with notice is thought of as one group, so following method is arranged: be equivalent among the SIB of the SIB of information of MBMS MODIFIED SERVICESINFORMATION and the information that transmission is equivalent to MBMS UNMODIFIEDSERVICES INFORMATION in transmission, similarly 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 similarly increases in transmission as extreme utilization.

In addition, this value label also can have the scope that sends 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 terminal, thereby can similarly send MBMS SIB, so can cut down expense with general broadcast message.

In addition, in the present embodiment, illustrated 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 is notified to terminal.At this moment, the point between conversion period is identical with UMTS to start with, and also the value of the Mod that 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 similarly are made as the interval between conversion period the transmission integral multiple at interval of MBMS SIB, also it can be defined as the transmission integral multiple at interval of MBMS SB.

In addition, in the present embodiment, 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 that sends with fixing resource and the part that sends 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).

Terminal need send with fixing resource MIB, so that 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 mentioned above 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 represents this situation.Here, Fig. 7 A represents to be made of each frequency band of a plurality of frequency bands the example of the sub-district of same area, and Fig. 7 B represents to be made 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 represents to provide MBMS with a plurality of frequency bands, sends the situation of information of the MBMS SB of each frequency band with each frequency band.Fig. 8 B represents to provide MBMS with a plurality of frequency bands, sends the situation of information of the MBMS SB of the information of MBMS SB of each frequency band and other frequency band with each frequency band.Fig. 8 C represents to provide MBMS with specific frequency band, sends the situation of information of the MBMS SB of the frequency band that MBMS is provided with each frequency band.Fig. 8 D represents following situation: provide MBMS with specific frequency band, providing the frequency band of MBMS that the information of MBMS SB is provided, frequency band in addition only sends the information of the frequency band that MBMS is being provided.Present embodiment 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 represented the situation of the same cells of other frequency bands to each frequency band difference 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 frequency band of MBMS special use.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 represents following situation: provide MBMS with a plurality of frequency bands that comprise the MBMS dedicated cell, sent the information of the MBMS SB of the information of MBMS SB of each frequency band and MBMS dedicated cell by the sub-district except the MBMS dedicated cell.Figure 10 B represents following situation: only provide MBMS with the MBMS dedicated cell, sent the information of the MBMS SB of MBMS dedicated cell by the sub-district except the MBMS dedicated cell.

By 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, by from a plurality of base stations in same frequency band and identical timed sending identical information, the function that signal is synthetic on wireless.By 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 mentioned above, SFN operation be characterized as the synthetic of signal between the base station, in order to realize this feature, 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) as operating corresponding transmission channel, prepare DSCH Downlink Shared Channel (Downlink Shared Channel with SFN; DL-SCH) as general transmission transmission channel.Therefore, we can say, transmit non-SFN operation information by DL-SCH by MCH transmission SFN operation information.

As mentioned above, 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 sends and not only goes 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 represents the configuration example of subframe.As 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.By such scheduling, also can provide SFN operation and non-SFN operation 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 obtains MBMS SIB classification and its data volume of SFN operation usefulness with MBMS SIB generation unit 203 from SFN operation described later.In addition, obtain MBMS SIB classification and its data volume of non-SFN operation usefulness with MBMSSIB generation unit 204 from non-SFN operation described later.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 output to MBMS SB generation unit 202.At this moment, the corresponding scheduling unit 201 of SFN is set SFN operation MBMS SIB, so that it can carry out the timed sending that SFN operates, and sets non-SFN operation 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 that uses schedule information with schedule information and non-SFN, and the MBMS SB that is generated is output to transmitting element 107.In addition, the information such as data volume with the MBMS SB that generated output to the corresponding scheduling unit 201 of SFN.

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

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

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

In addition, in the present embodiment, illustrated 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, but also can define the SFN operation with MBMS SB and non-SFN operation MBMS SB as MBMS SB.In addition, be not under the situation of SB of the such MBMS special use of MBMS SB at SB for routine, also can be defined as carry out the SFN operation SIB with SB with carry out the SIB SB that non-SFN operates.

(execution mode 3)

In execution mode 2, illustrated 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 of the terminal of the MBMS data that the imagination request is specific is few, and these terminals concentrate on the situation of specific sub-district.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 of the terminal that has the specific MBMS data of request, its efficient is higher.Figure 13 represents this situation.

SFN zone shown in Figure 13 sends same information with identical timing and same frequency for carrying out the unit of SFN operation in all sub-districts in this scope.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 send 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 of the terminal of these MBMS data of request etc. in order only to detect the such situation of 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 represents 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, will begin to provide professional advisory from the base station to terminal, in ST302, the notification of information that will comprise what kind of business of expression beginning from the base station sends to terminal.

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

In ST305, notify the RB information that sends MTCH by RB information (RB Info) being sent to terminal from the base station, in ST306,, data are sent to terminal from base station reality by MTCH.

Consideration sends message by 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 by MCH, and in Figure 14 C, the MBMS controlled step that expression is following: the message that sends ST301 to ST303 by MCH, based on the result of counting response, after non-SFN operation is carried out in decision, send the message of ST305 and ST306 by the DL-SCH of non-SFN operation.

In addition, in Figure 14 G, opposite with the MBMS controlled step shown in Figure 14 C, the MBMS controlled step that expression is following: the message that sends ST301 to ST303 by DL-SCH, result based on counting response, after non-SFN operation is carried out in decision, send the message of ST305 and ST306 by the MCH of SFN operation.

Yet, when between SFN operation and non-SFN operation, switching like this, have following problem.That is to say,, need receive both sides' message in terminal to each is professional when still switching by non-each business of SFN operation utilization by 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 in 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, as 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 that MCH or DL-SCH send by the channel identical with hereto MBMS controlled step.Under the situation shown in Figure 15 A, send the message of ST301 to ST303 by MCH.Therefore, also send the count results of ST351, and decision is with MCH or with the message of DL-SCH notice ST305 and ST306 according to count results by MCH.Under the situation shown in Figure 15 B, send the message of ST301 to ST303 by 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 by 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 counting processing unit 402 and MBMS Database Unit 105 is changed to MBMS Database Unit 403.

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 the control information that whether the SFN operation is applicable 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, the MBMS controlled step based on shown in Figure 15 A illustrates the action of base station shown in Figure 16 400.At first, send the notice of ST301 and the access information of ST302, so the information that is used to generate corresponding SIB outputs to the SFN operation with MBMSSIB generation unit 203 from MBMS Database Unit 403 by MCH.

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 the corresponding scheduling unit 201 of SFN, 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 provide this business in this sub-district from receiving element 401 outputs, when providing, judge whether carry out the SFN operation.Result of determination is output to MBMS Database Unit 403.

In MBMS Database Unit 403, whether based on the result of determination from 402 outputs of counting processing unit, judging needs to send the RB information of ST305 and the MTCH of ST306.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 by the SFN operation, count results is output to SFN operation MBMS SIB generation unit 203, and when sending the access information of ST303 by non-SFN operation, count results is output to non-SFN operation 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 operation 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 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, enter 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, enters ST506, and is being judged to be when not carrying out sending, and enters ST511, end process.In ST506, judge whether to carry out SFN operation, being judged as when carrying out, enter ST507, and be judged as when not carrying out, enter ST509.

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

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

By 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 represents the block diagram of structure of the terminal 600 of embodiment of the present invention 3.In Figure 18, broadcast message receiving element 601 receives 400 broadcast messages that send from the base station, information based on from MIB processing unit 602 described later, MBMS SB processing unit 603 and 605 outputs of MBMS control unit outputs to the MIB that broadcast message comprised that receives 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 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 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 according to needs such as countings, generate this response, and the response that is generated is outputed to MBMS related news transmitting element 606.

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 400 MBMS data that send from the base station according to the indication of the MBMS Data Receiving of exporting from MBMS control unit 605.

By 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 by counting the existence of sense terminals immediately, perhaps also be difficult to the existence of sense terminals sometimes by counting in certain sub-district.Thus, consider processing is counted in each sub-district.In counting is handled, need to adjust probability factor, so that the terminal 600 of right quantity is beamed back response.Consider this processing different situation between the base station.Figure 19 represents the action of this moment.

Figure 19 A represents always to transmit by 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 needing to change with same settings.For the such action of correspondence, consider that (the next access information of expression sends by MCH or sends by DL-SCH in the message of the access information of 1≤n≤N-1) at ST702-n.

In Figure 19 C, send access information by DL-SCH from the beginning.At this moment, need represent to send access information by the notice of ST301 with DL-SCH.Also can realize this action by 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 as 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 send,, 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, described 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 a part of SFN of carrying out as shown in figure 20 operates.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 terminal, carries out the SFN operation of a part.At this moment, consider to use in the sub-district that detects 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 the count results that is notified to terminal, thereby need not to send the message that is suitable for the SFN operation and be suitable for both of message of non-SFN operation, can carry out the MBMS controlled step efficiently.

In addition, in the present embodiment, 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 of terminal, sometimes between ST303-1 to ST303-N, return, return response with any timing and get final product.

In addition, shown in Figure 13,14 and 17, expression notice is that message and RB message are the situation of a message in the present embodiment, 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 of 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 terminal.More specifically, as shown in figure 21, initial between next conversion period, MICH impels the such action of notification message (MBMS MODIFIED SERVICESINFORMATION and MBMS UNMODIFIED SERVICES INFORMATION) that receives MCCH.In addition,,, use the ID that has gathered a plurality of business that terminal is indicated here as MICH.Therefore, as terminal, be not to notify terminal in fact to want the business that receives sometimes.Therefore, the content of terminal check notice finally judges whether to exist the own business that will receive.

The action of this MICH becomes and Page Indication Channel (the Paging Indicator Channel that carries out the notice of general calling in UMTS; PICH) Jin Si notion.Therefore, in LTE, also be considered the notion approximate with PICH.Figure 22 represents the notion of the PICH among the LTE.As shown in the drawing, send PICH by 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.Terminal includes paging information by 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 by the L1/L2 control channel.

Yet, as shown in Embodiment 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 to prepare two kinds,, also need to wait for two MICH terminal for MICH.Its result, for 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, for MICH, also need two kinds this moment.

Therefore, can consider for MBMS SB definition MICH rather than for notice definition MICH.Figure 23 represents its schematic diagram.As shown in figure 23, by with the subframe identical (perhaps time slot (slot) and Transmission Time Interval (Transmission Time Interval with sending MBMS SB; TTI)) send MICH.Thus, 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, as shown in figure 23, might in the subframe (perhaps slot and TTI) that sends 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 freely dispatching on time or frequency.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, append MICH generation unit 802 and MICH and sent regularly adjustment unit 804, 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 with business information and set information output to the SFN operation with MBMS SIB generation unit 203 and non-SFN operation with MBMS SIB generation unit 204, 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 adjusting 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 that sends 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 output to MICH and sends 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 needs to consider to be used to provide the control information of new business to be sent out.As shown in Embodiment 1, it has and identical functions between the conversion period in UMTS, so can consider the recovery value label or between suitable conversion period.Under the former situation, need from by send for the information of new business upgraded for the value label of control information, original M BMS SB sends MICH.Figure 25 represents 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 terminal is followed the renewal that is worth label etc., 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 mentioned above, need to consider that SFN operation and non-SFN manipulate the situation between different conversion periods.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.

By above action, terminal can utilize a MICH to wait for MBMS data of being operated by SFN and the MBMS data of being operated by non-SFN.

Figure 26 represents the block diagram of structure of 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 output 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.

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

Like this, according to execution mode 4, by sending MBMS SB and MICH with identical transmission unit such as identical TTI or slot, terminal can utilize a MICH etc. pending the MBMS data of SFN operation and both of MBMS data that carried out non-SFN operation, the stand-by period of terminal can be shortened, thereby power consumption can be lowered.

In addition, in the present embodiment, expression sends MICH by 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 subframes (or slot and TTI) of the timing that sends MBMS SB.By such action, can avoid taking defeat of MICH etc.Figure 27 represents its action example.

In addition, in the present embodiment,, the information that is used to represent business is shown as the content that MICH comprised.In addition, consider to comprise at carry out the SFN operation for the notice of its business and still carry out the information of non-SFN operation as information.At this moment, 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 by MICH by MICH.When in LTE, using this notion, the group can be divided into by the SFN operation and notify and notify by non-SFN operation.

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

In addition, each functional block that is used for the explanation of above-mentioned each execution mode LSI of typically being used as integrated circuit realizes.These pieces both can be integrated into a chip individually, also it part or all can be integrated into a chip.Though be called LSI herein,, 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 of perhaps reconfigurable LSI inside and the reconfigurable processor of setting.

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