Identifying information can be the 2ndIn broadcast message for the relation between multiple frequency bands and the kind of travelling carriage is shown. For example, can use community IDOr in same community unique numbering etc. as identifying information. In the situation that using community ID as identifying information,To 1 multiple community ID of cell allocation. In addition, travelling carriage may be identified as respectively (imaginary) by multiple frequency bandsDifferent communities.
The 1st broadcast channel 4a for example sets respectively in multiple frequency bands. The 2nd broadcast channel 4b can be respectively multipleIn frequency band, set, also can only in a part of frequency band, set. In the latter's situation, considering has the frequency band in regulationThe method of for example, setting in (, at frequency axis in central frequency band) or operable at the 2nd kind of travelling carriageThe method of setting in frequency band. In addition, in the Radio Resource region of specifying according to frequency and time, can be by the 2ndBroadcast channel 4b is set as and the 1st broadcast channel 4a adjacency. In addition also the 2nd broadcast channel 4b can be set,For with synchronizing channel adjacency for sending synchronizing signal.
In addition, this GSM for example can be embodied as LTE-A system. In this situation, can be by the 1st kindTravelling carriage is as the travelling carriage corresponding to LTE, using the 2nd kind of travelling carriage as the reality corresponding to the travelling carriage of LTE-AExisting. In addition broadcast channel that, can be using the 1st broadcast channel 4a as common definition in LTE and LTE-A, generalThe 2nd broadcast channel 4b realizes as the expansion broadcast channel not defining in LTE. In addition, in LTE-ASometimes respectively above-mentioned multiple frequency bands are called component carrier (CC:ComponentCarrier) or carrier component (CC:CarrierComponent)。
In the mobile communications device of this 1st embodiment, by radio communication device 1, generate the 1st and theThe 1st broadcast message using in the processing of 2 kinds of travelling carriages, generate in the processing of the 2nd kind of travelling carriage, use the2 broadcast messages. Send the 1st broadcast message by the 1st broadcast channel 4a, send the by the 2nd broadcast channel 4b2 broadcast messages. In addition, receive by mobile communications device 2 the 1st broadcast sending by the 1st broadcast channel 4aInformation and the 2nd broadcast message sending by the 2nd broadcast channel 4b. The the 1st and the 2nd wide based on what receiveBroadcast information, control communicating by letter between radio communication device 1 and mobile communications device 2.
, by the 1st kind of travelling carriage not with reference to (or can not with reference to) and the broadcast message of the 2nd kind of travelling carriage reference is logicalCrossing the broadcast channel of the broadcast message that is different from the 1st kind and the 2nd kind common reference of travelling carriage broadcasts. Thus,Can realize efficiently the Control on Communication of the existence of having considered multiple travelling carriage.
For example, in the situation that realizing as LTE-A system, consider the broadcast message being defined by LTE to pass throughBroadcast channel is in the past broadcasted, and in addition, the broadcast message of being appended by LTE-A is entered by expansion broadcast channelRow broadcast. In this situation, corresponding to the travelling carriage (not corresponding to the travelling carriage of LTE-A) of LTE can receive withPast broadcast message, can receive the broadcast message of appending corresponding to the travelling carriage of LTE-A. , can realize toolThere is the efficient LTE-A system of backwards compatibility.
And, in the 2nd broadcast message, comprise the relation between multiple frequency bands and the kind of travelling carriage that illustrates information andBroadcast, thus, can easily carry out the distribution control of Radio Resource. , specify in advance the 2nd kind of movementIn platform, want to use the frequency band of (or not wanting to use) and broadcast, thus, can be easily by the 2nd kind of movementPlatform is directed to a part of frequency band. Particularly, the in the situation that of LTE-A system, only make corresponding to the travelling carriage of LTEWith 1 frequency band, on the other hand, can use multiple frequency bands corresponding to the travelling carriage of LTE-A, therefore above-mentioned guidingUseful realizing on this aspect of utilization ratio that improves Radio Resource.
In the 2nd following embodiment, consider the wireless communications method of the 1st embodiment to be applied to LTE-AThe situation of system. But, above-mentioned wireless communications method can certainly be applied to the GSM of other kinds.
[the 2nd embodiment]
Fig. 2 is the figure that the GSM of the 2nd embodiment is shown. The GSM tool of the 2nd embodimentThere are base station 100, relay station 200 and travelling carriage 300,400. The mark of communicating by letter of this GSM and LTE-AAccurate corresponding.
Base station 100 is directly or can carries out radio communication with travelling carriage 300,400 via relay station 200Radio communication device. Base station 100 is connected with wired upper network (not shown), at upper network and travelling carriage300, between 400, transmit data. 3 communities (sometimes also referred to as sector) of subordinate are managed in base station 100. Base station 100In radio communication, use 5 component carriers (following, to be called CC).
Relay station 200 is in subordinate's community, to exist travelling carriage 300,400, base station 100 with moveBetween moving platform 300,400, radio communication is carried out the radio communication device of relaying. Relay station 200 is also referred to as relay station.5 CC that relay station 200 service band in radio communication is identical with base station 100.
Travelling carriage the 300, the 400th, is connected with base station 100 or relay station 200 and carries out the wireless terminal dress of radio communicationPutting, for example, is portable phone or mobile information terminal apparatus etc. Travelling carriage 300 at downlink (from base station 100Or relay station 200 is to the Radio Link of travelling carriage 300) in, can receive data with 5 CC at most simultaneously,Up-link (from travelling carriage 300 to base station 100 or the Radio Link of relay station 200), can be at most simultaneouslySend data with 2 CC. On the other hand, travelling carriage 400 only uses in downlink and up-link1 CC carrys out sending/receiving data arbitrarily.
, in the present embodiment, use the travelling carriage of multiple CC to be called LTE travelling carriage by not integrating herein, willCan integrate and use the travelling carriage of multiple CC to be called LTE-A travelling carriage. Travelling carriage 300 is LTE-A travelling carriages,Travelling carriage 400 is LTE travelling carriages. LTE-A travelling carriage and these both sides of LTE travelling carriage can with base station 100 andRelay station 200 connects.
In addition, in 3GPP, the communication standard of LTE is by the description definition of version 8 (release8), LTE-ACommunication standard by the description definition of version 10 (release10). But, corresponding to the travelling carriage of version 10 notMust be all to integrate the travelling carriage (LTE-A travelling carriage) that uses multiple CC. , also may exist and versionThe LTE travelling carriage of 10 correspondences. In addition, in the present embodiment, by the travelling carriage corresponding to version 9 with corresponding toThe travelling carriage of version 8 is similarly as the processing of LTE travelling carriage.
Fig. 3 is the figure that the setting example of component carrier is shown. As shown in Figure 3, base station 100 and relay station 200 use5 CC. In the feelings that use FDD (FDD:FrequencyDivisionDuplex) for two-way communicationUnder condition, respectively for downlink (DL:DownLink) and up-link (UL:UpLink), guarantee CC#1～The frequency band of #5. Below, in the situation that being only called CC#1～#5, refer to the group of the frequency band of DL and the frequency band of UL.The CC of DL and UL bandwidth is separately 20MHz, and all bandwidth are 100MHz. Base station 100 andRelay station 200 carries out respectively the distribution (scheduling) of Radio Resource for CC#1～#5.
In addition, in the example of Fig. 3, realize two-way communication by FDD, but also can pass through time division duplex (TDD:TimeDivisionDuplex) realize two-way communication. In this situation, on frequency axis, do not distinguish DL and ULAnd 5 CC are set. In addition, in the example of Fig. 3, the bandwidth of whole CC is set for 20MHz, butAlso can be set as other bandwidth (for example, 5MHz, 10MHz, 15MHz etc.). In addition, can be not yet byThe bandwidth of whole CC is set as identical.
In addition, in the example of Fig. 3, UL Radio Resource is arranged on to lower frequency side, DL Radio Resource is arranged onHigh frequency side. The transmission loss of the signal that frequency is low is less, therefore by UL Radio Resource being arranged on to lower frequency side, energyEnough the transmitted power of travelling carriage 300,400 is suppressed for lower. But, also can be by UL Radio Resource and DLThe configuration of Radio Resource is put upside down.
Thus, travelling carriage 300 is integrated the multiple CC in CC#1～#5, can be to having used than 1 CC'sThe wide bandwidth (for example, 40MHz, 60MHz, 80MHz, 100MHz etc.) of bandwidth (for example, 20MHz)Data are carried out sending/receiving.
Herein, CC#1～#5 can all be set to 800MHz frequency band, 2.5GHz frequency band, 3.5GHz frequency band etc.In frequency band any 1 can scattering device be also different multiple frequency bands. By to the multiple companies that belong to same frequency bandContinuous or discontinuous CC integrates and is called carrier aggregation (CarrierAggregation). On the other hand, by rightThe CC that belongs to different frequency band integrates and is called spectrum aggregating (SpectrumAggregation).
Fig. 4 is the figure that the 1st example of carrier aggregation is shown. In the example of Fig. 4, in 3.5GHz frequency band, asOperable frequency band in radio communication, prepared the frequency band of 4 discontinuous 5MHz width and 3 discontinuousThe frequency band of 20MHz width. And, the frequency band of 4 5MHz is integrated, form thus 20MHz widthCC#2. In addition, the frequency band of 1 20MHz width is defined as to CC#3.
Travelling carriage 300 for example can be by carrier aggregation the frequency band using CC#2, CC#3 as 40MHz (in logicBe 1 frequency band) use. In this situation, in fact, travelling carriage 300 uses belong to 4 of 3.5GHz frequency bandThe frequency band of the frequency band of 5MHz width and 1 20MHz width. In addition, in Fig. 4, enumerated and belonged to 3.5GHzThe example of frequency band, even if but other the frequency band such as 800MHz frequency band also can compare 20MHz by integrating frequency widthLittle frequency band and utilizing.
Fig. 5 is the figure that the 2nd example of carrier aggregation is shown. In the example of Fig. 5, in 3.5GHz frequency band, asOperable frequency band in radio communication, has prepared the frequency band of continuous 80MHz width. And, this 80MHzThe frequency band of width is divided into 4, is defined as respectively the CC#2～#5 of 20MHz width.
Travelling carriage 300 for example can be by carrier aggregation the frequency band using CC#2, CC#3 as 40MHz (in logicBe 1 frequency band) use. In this case, in fact travelling carriage 300 uses belong to the continuous of 3.5GHz frequency bandThe frequency band of 80MHz width in a part.
Fig. 6 is the figure that the example of spectrum aggregating is shown. In the example of Fig. 6, in 2GHz frequency band, as in nothingCan service band in line communication, prepare the frequency band of continuous 20MHz width. In addition, at 3.5GHz frequency bandIn, as operable frequency band in radio communication, prepare the frequency band of continuous 80MHz width. And,The frequency band of the 20MHz width of 2GHz frequency band is defined as CC#1, and the frequency of the 80MHz width of 3.5GHz frequency bandBand is split into 4, is defined as respectively the CC#2～#5 of 20MHz width.
Travelling carriage 300 can the frequency band using CC#1～#5 as 100MHz (be by spectrum aggregating in logic for example1 frequency band) use. In this case, in fact travelling carriage 300 uses the 20MHz that belongs to 2GHz frequency bandThe frequency band of width and the frequency band of continuous 80MHz width that belongs to 3.5GHz frequency band.

Figure 20 is the routine sequence chart of the 1st connection illustrating from travelling carriage to base station. This sequence illustrates as LTE-A movesThe situation that the travelling carriage 300 of moving platform is connected with base station 100. The situation that travelling carriage 300 is connected with relay station 200 is alsoSame sequence.
(step S11) base station 100 sends synchronizing signal by CC#1～#5 P-SCH and S-SCH separately.ID at use community ID as CC#1～#5, each CC sends different synchronizing signals. In addition,The in the situation that of managing multiple community in base station 100, send synchronizing signal by each community. Similarly, relay station 200Also send synchronizing signal.
The synchronizing signal that (step S12) travelling carriage 300 sends based on base station 100, according to each cell detection withoutThe timing of line frame, obtains and the synchronizeing of base station 100. In the case of the timing of the radio frames of CC#1～#5 is consistent,Can not carry out timing to whole CC detects. Similarly, travelling carriage 300 is obtained and the synchronizeing of relay station 200.
(step S13) base station 100 sends the contrast signal as pilot signal by CC#1～#5 respectively. LogicalThe contrast signal of crossing CC#1～#5 transmission can be all same signal. Similarly, relay station 200 also sends referenceSignal.
The contrast signal that (step S14) travelling carriage 300 sends based on base station 100, comes according to each cell measurementFrom the received power of base station 100. Can measure received power for any 1 CC, also can be for multipleCC measures received power. In the former situation, can pre-determine the frequency band of determination object. In the latter's situation,Can be the received power from base station 100 by the maximum of the received power of multiple CC or mean value definition. EquallyGround, travelling carriage 300 is to measuring from the received power of relay station 200.
The received power of (step S15) travelling carriage 300 based on measuring in step S14, selects travelling carriage 300The community connecting. Preferably, the travelling carriage 300 prominent communities of selective reception. Herein, be made as and select base station100 subordinate's community.
(step S16) base station 100 sends (broadcast) broadcast message by CC#1～#5 PBCH separately.In addition, send (broadcast) by the E-PBCH arranging at least 1 of CC#1～#5 and expand broadcast message.
(step S17) travelling carriage 300 sends the expansion broadcast message of (broadcast) based on base station 100, confirmThe CC that in CC#1～#5, LTE-A travelling carriage can connect.
The LTE-A travelling carriage operable CC of (step S18) travelling carriage 300 from confirming among step S17Middle selection is for the CC of random access. In the case of the candidate who has multiple CC, can select any 1,Also optionally connected receipts are prominent.
In addition, in the flow process example of Figure 20, at the CC that has selected choice for use behind the community connecting, but also can be sameTime select community and CC. For example, can not dwindle the scope of community, and whole CC to the peripheral cell detectingMeasure received power, from these CC, select the CC that LTE-A travelling carriage can connect and received power is larger. This, also can, before selection community, confirm for each peripheral cell the CC that LTE-A travelling carriage can connect outward, rightThose CC measure received power, the CC that selective reception power is larger.
(step S19) travelling carriage 300 is to wrapping in the broadcast message corresponding with the CC selecting in step S18Contain, for example, confirm for the information (information of bandwidth, is shown) being connected with this CC. Then, by choosingThe PRACH that the UL radio frames of the CC selecting out arranges, sends random access preamble to base station 100.
(step S20) is that LTE-A travelling carriage can connect at the CC that has received random access preambleCC, and, existing in the idle situation of Radio Resource of compatible travelling carriage 300, base station 100 allows travelling carriage300 connection. In the situation that having allowed to connect, base station 100 is by receiving random access preambleThe PDSCH that the DL radio frames of CC arranges sends the accidental access response that represents to allow connection. Now, base station 100UL allocation of radio resources for step S21 is arrived to travelling carriage 300.
(step S21) travelling carriage 300 can normally communicate in order to be confirmed whether, by step S20The UL Radio Resource (PUSCH) distributing is that scheduled transmission sends to base station 100 by the message of regulation.
(step S22) base station 100 is confirmed whether normally to have received scheduled transmission. Then, as response message,By illustrate reception could competition solve send to travelling carriage 300 by PDSCH.
Thus, receive and reference expansion broadcast message as the travelling carriage 300 of LTE-A travelling carriage, thus, canBefore random access, confirm the CC that LTE-A travelling carriage can use. Thus, can not attempt moving with LTE-AThe out of use CC of platform connects, and can suppress useless random access procedure. In addition, by confirming in advance LTE-AThe CC that travelling carriage can use, the scope that can dwindle the CC that will measure received power. Thus, alleviate travelling carriageThe load of 300 processing.
On the other hand, can not be with reference to expansion broadcast message as the travelling carriage 400 of LTE travelling carriage. Therefore, even ifIn the situation that base station 100 or relay station 200 limit the out of use CC of LTE travelling carriage, also cannot beBefore random access, confirm which CC is the CC that LTE travelling carriage can use. Therefore, random access may be lostLose.
Figure 21 is the routine sequence chart of the 2nd connection illustrating from travelling carriage to base station. This sequence shows as LTE movesThe situation that the travelling carriage 400 of moving platform is connected with base station 100. The situation that travelling carriage 400 is connected with relay station 200 is for sameThe sequence of sample.
(step S31) base station 100 sends synchronizing signal by CC#1～#5 P-SCH and S-SCH separately.The in the situation that of managing multiple community in base station 100, send synchronizing signal according to each community. Similarly, relay station200 also send synchronizing signal.
The synchronizing signal that (step S32) travelling carriage 400 sends based on base station 100, according to each cell detection withoutThe timing of line frame, obtains and the synchronizeing of base station 100. In the case of using the ID of community ID as CC, mobilePlatform 400 is identified as mutually different community by CC#1～#5 (imaginary) sometimes. Similarly, travelling carriage 400 is gotMust with the synchronizeing of relay station 200.
(step S33) base station 100 sends the contrast signal as pilot signal by CC#1～#5 respectively. WithSample ground, relay station 200 also sends contrast signal.
The contrast signal that (step S34) travelling carriage 400 sends based on base station 100, according to each community and everyIndividual CC, measures the received power from base station 100. Similarly, travelling carriage 300 is measured from relay station 200Received power.
The received power of (step S35) travelling carriage 400 based on determining in step S34, selects travelling carriage 400The community connecting. Preferably, the travelling carriage 400 prominent communities of selective reception. Select base station 100 herein,Subordinate's community.
(step S36) base station 100 sends (broadcast) broadcast message by CC#1～#5 PBCH separately.
(step S37) travelling carriage 400 is selected to use from the CC#1～#5 of the community selected among step S35In the CC of random access. In CC#1～#5, can select 1 arbitrarily, also can selective reception powerLarge. In addition, in the situation that CC#1～#5 (imaginary) is identified as mutually different community by travelling carriage 400,Also the received power based on each CC be can consider, the selection of community and the selection of CC carried out simultaneously.
(step S38) travelling carriage 400 is to wrapping in the broadcast message corresponding with the CC selecting in step S37Contain, for example, confirm for the information that is connected with this CC (, representing the information of bandwidth). Then, by choosingThe PRACH that the UL radio frames of the CC selecting out arranges, sends random access preamble to base station 100. ButThat herein, the CC that is made as selection is the CC that LTE travelling carriage can not connect.
(step S39) is the CC that LTE travelling carriage can not connect at the CC that has received random access preambleSituation under, the connection of travelling carriage 400 is refused in base station 100. In the situation that having refused to connect, base station 100 is by rightReceive the PDSCH of the DL radio frames setting of the CC of random access preamble, send and represent that refusal connectsThe accidental access response connecing. In addition, does not reply random access preamble base station 100.
(step S40) travelling carriage 400 receives the accidental access response that represents that refusal connects, or, if from sending outSend random access preamble to start not reply with interior at the appointed time, be judged as random access failure. Then,Travelling carriage 400 is chosen in other CC of the community of selecting in step S35.
(step S41) travelling carriage 400 is to comprising in the broadcast message corresponding with the CC selecting in step S40, confirm for the information being connected with this CC. Then, arranged by the UL radio frames to the CC selectingPRACH, base station 100 is sent to random access preamble. The CC that is made as selection herein, is that LTE movesThe CC that moving platform can connect.
(step S42) is the CC that LTE travelling carriage can connect at the CC that receives random access preamble,And, existing in the idle situation of Radio Resource of compatible travelling carriage 400, base station 100 allows travelling carriage 400Connection. In the situation that having allowed to connect, base station 100 is by the CC's that receives random access preambleThe PDSCH that DL radio frames arranges, sends the accidental access response that represents to allow connection. Now, base station 100UL allocation of radio resources for step S43 is arrived to travelling carriage 400.
(step S43) travelling carriage 400 can normally communicate in order to be confirmed whether, by step S42The UL Radio Resource (PUSCH) distributing, sends to base station 100 by scheduled transmission.
(step S44) base station 100 is confirmed whether normally to have received scheduled transmission. Then, as response message,By represent receive could competition solve send to travelling carriage 400 by PDSCH.
Thus, can not, with reference to expansion broadcast message, therefore, connect at random as the travelling carriage 400 of LTE travelling carriageBefore entering, can not confirm the CC that LTE travelling carriage can use. Thus, random access may be failed. In addition, due toCan not confirm the CC that LTE travelling carriage can use, therefore can not dwindle in advance the model of the CC that will measure received powerEnclose.
Then, the relation between CC#1～#5 and E-PBCH is described.
Figure 22 is the figure that the 1st sending/receiving example of expansion broadcast message is shown. In the example of Figure 22, base station 100Or relay station 200 controls, to make LTE travelling carriage use CC#1～#3, LTE-A travelling carriage is used CC#4、#5。
In addition, base station 100 or relay station 200 arrange PBCH and E-PBCH to whole CC#1～#5. RespectivelyIn the PBCH of CC, send the information comprising for being connected with this CC in interior broadcast message. Sent by PBCHBroadcast message sometimes because the difference of CC is different. In each E-PBCH, send comprise illustrate CC#1～#5 withThe information of the relation between the kind of travelling carriage is in interior expansion broadcast message. The expansion broadcast letter being sent by E-PBCHBreath can be identical in whole CC.
In this situation, receive by E-PBCH arbitrarily in CC#1～#5 as the travelling carriage 300 of LTE-A travelling carriageThe expansion broadcast message sending. LTE-A travelling carriage according to the known CC#4 of expansion broadcast message, the #5 that receiveThe CC that can use. Then, the side in selection CC#4, #5 is as the CC using in random access. CanWhich in selection CC#4, #5 be measurement result based on received power judge. In the example of Figure 22, moveMoving platform 300 is with reference to the expansion broadcast message of being broadcasted by CC#4, and selection CC#4.
Select CC#4 as in random access, use CC time, travelling carriage 300 is with reference to the PBCH by CC#4The broadcast message sending, sends random access preamble by the PRACH of the UL radio frames setting to CC#4 and believesNumber. Thus, start the process of the random access between base station 100 or relay station 200 and travelling carriage 300. Thus,In the example of Figure 22, whole CC is provided with to E-PBCH, therefore need only reference 1 CC arbitrarily, justCan know the CC that LTE-A travelling carriage can use.
In addition, travelling carriage 300 is LTE-A travelling carriages, therefore CC#4, #5 can also be integrated and send out in dataIn sending/receiving, use. Even if in this case, in the time of random access, also first use 1 CC (CC#4) to comeThe process of carrying out. Then, between base station 100 or relay station 200 and travelling carriage 300, connect, based on base station100 or the basis of the control of relay station 200 on, the CC of other that can also use that LTE-A travelling carriage can use(CC#5)。
In addition, base station 100 or relay station 200 can dynamically change in CC#1～#5 according to signal intelligenceThe CC that LTE-A travelling carriage can use. In this situation, base station 100 or relay station 200 dynamically change by E-PBCHThe content of the expansion broadcast message sending.
Figure 23 is the figure that the 2nd sending/receiving example of expansion broadcast message is shown. In the example of Figure 23, base station 100Or relay station 200 arranges PBCH in whole CC#1～#5, only LTE-A travelling carriage can use CC#4,E-PBCH is set in #5. In the PBCH of each CC, send the information comprising for being connected with this CC interiorBroadcast message. In the E-PBCH of CC#4, #5, send comprise illustrate CC#1～#5 and travelling carriage kind itBetween the information of relation in interior expansion broadcast message.
In this situation, receive the E-PBCH by the side in CC#4, #5 as the travelling carriage 300 of LTE-A travelling carriageThe expansion broadcast message sending. LTE-A travelling carriage according to the known CC#4 of expansion broadcast message, the #5 that receiveThe CC that can use. Then, the side in selection CC#4, #5 is as the CC using in random access. Thus,In the example of Figure 23, in the CC that only can use at LTE-A travelling carriage, E-PBCH is set, therefore canEnough save Radio Resource.
In addition, as long as pre-determine in the CC that only can use at LTE-A travelling carriage, E-PBCH is set, travelling carriage300 just can be judged as the CC that LTE-A travelling carriage can use by the CC that E-PBCH detected. In this situation,In the expansion broadcast message sending at the E-PBCH by CC#4, #5, can not comprise the information about other CC.
In addition, base station 100 or relay station 200 also can only arrange E-PBCH to the side in CC#4, #5. ,As long as E-PBCH is set at least one in the CC that can use at LTE-A travelling carriage. In addition, alsoThe CC that is provided with E-PBCH can be called to main CC or dominant frequency band, other CC are called to expansion CC or expansionFrequency band.
Figure 24 is the figure that the 3rd sending/receiving example of expansion broadcast message is shown. In the example of Figure 24, base station 100Or relay station 200 arranges PBCH in whole CC#1～#5, only on frequency axis, be arranged in CC#1～#5'sIn the CC#3 of the heart, E-PBCH is set. In the PBCH of each CC, send the letter comprising for being connected with this CCBreath is in interior broadcast message. In the E-PBCH of CC#3, send and comprise the kind that CC#1～#5 and travelling carriage are shownThe information of the relation between class is in interior expansion broadcast message.
In this situation, receive the expansion being sent by the E-PBCH of CC#3 as the travelling carriage 300 of LTE-A travelling carriageExhibition broadcast message. That LTE-A travelling carriage can use according to the known CC#4 of expansion broadcast message, the #5 that receiveCC. Then, the side in selection CC#4, #5 is as the CC using in random access. Thus, at figureIn 24 example, only in the CC of regulation, E-PBCH is set, therefore can saves Radio Resource. In addition,300 CC (for example, being positioned at the CC at CC#1～#5 center on frequency axis) with reference to regulation of travelling carriage,Can make the processing simplicity of travelling carriage 300, can lower and process load.
According to the GSM of this 2nd embodiment, base station 100 and relay station 200 can be according to movementsThe kind of platform limits the CC that can connect. Therefore, simultaneous at LTE-A travelling carriage and LTE travelling carriageIt is easy that scheduling under environment becomes. And, be easy to wide band allocation of radio resources to LTE-A travelling carriage.
In addition, LTE-A travelling carriage is expanded broadcast message by reference, can with base station 100 or relay station 200Before connecting, know operable CC. Thus, even if limiting and can connect because of the kind of travelling carriageIn the situation of the CC connecing, also can successfully connect processing. In addition, LTE-A travelling carriage can be little in selectionThe scope of dwindling the CC that measures received power when district or selection CC, alleviates and processes load. In addition, can shortenThe processing time (comprising while switching) while selecting community.
For example, suppose that LTE-A travelling carriage detects 3 peripheral cells, in Ge community, 2 quilts in 5 CCBe assigned to LTE-A travelling carriage. In this case, if do not try one's best selective reception power with reference to expanding broadcast messageLarger CC, becomes for 5 × 3=15 CC and measures received power. On the other hand, if wide with reference to expansionBroadcast information and got rid of the out of use CC of LTE-A travelling carriage, as long as measure and receive for 2 × 3=6 CCPower. , the processing of LTE-A travelling carriage is relieved to 2/5ths left and right.
Certainly, expand broadcast channel except illustrating the information of the corresponding relation between multiple CC and the kind of travelling carriage,Can also be used for LTE-A travelling carriage to send the various information that will broadcast. In addition, also can be by uncertain in LTEThe new broadcast channel of justice is called " expansion broadcast channel " title in addition. For example, can be by broadcast channel in the pastAnd a side in expansion broadcast channel is called the 1st broadcast channel, the opposing party is called to the 2nd broadcast channel.
Below only show principle of the present invention. To those skilled in the art, can carry out various distortion andChange, the invention is not restricted to the above-mentioned precision architecture that illustrates and illustrate and application examples, corresponding whole variation andEquivalent all falls in the scope of the present invention being limited by claims and equivalent thereof.
