Embodiment
The embodiment of the present invention provides a kind of broadcast information transmission method and device, sends in order to the broadcast message realizing in carrier aggregation system, and compatible existing LTE Release 8 systems, the system resource that need to take is less.
Consider the compatibility with existing LTE system, the broadcast message of whole carrier aggregation system can be sent separately by each member carrier in carrier aggregation system, as shown in Figure 2, such benefit is the broadcast message that subscriber equipment (UE) can read from any one member carrier carrier aggregation system in initial access process, but can cause certain wasting of resources.In addition, the part that can also set in advance in carrier aggregation system (can be one, also can be multiple, but not all) member carrier is main member carrier, the broadcast message of whole carrier aggregation system all only sends on this main member carrier, as shown in Figure 3, the benefit of doing is like this system resource of having saved for sending broadcast message, but all UE all must be from the main member carrier of system the broadcast of reading system, therefore UE cannot be from all member carriers access polymerization carrier systems.
The broadcast message of described whole carrier aggregation system, comprises the exclusive broadcast message of expanding in the broadcast message of existing LTE system and LTE-A system.
If take into account system resource overhead and backwards compatibility simultaneously, the broadcast message of whole carrier aggregation system can be splitted into two parts and send in different ways respectively.The broadcast message of considering existing LTE system is the essential broadcast messages of LTE Release 8 systems, therefore this partial information can be sent on each member carrier in carrier aggregation system; And the exclusive broadcast message of LTE-A system can be chosen on one or more member carriers and send.Therefore,, referring to Fig. 4, the broadcast message delivery plan of a kind of carrier aggregation system that the embodiment of the present invention provides comprises step:
S101, the basic broadcast message of determining carrier aggregation system and exclusive broadcast message.
S102, each member carrier passing through in carrier aggregation system send described basic broadcast message, and send described exclusive broadcast message by predefined main member carrier in carrier aggregation system, wherein, the number of main member carrier is less than the number of all member carriers that comprise in carrier aggregation system.
The method also comprises:
Send the indication information of the exclusive broadcast message for obtaining carrier aggregation system by each member carrier in carrier aggregation system.
Be used for the indication information of the exclusive broadcast message of obtaining carrier aggregation system, can send by the extend information territory of Master Information Block MIB or system information block SIB, also can send by the SIB setting in advance separately.Wherein, MIB sent before SIB.The extend information territory of MIB or SIB, and described in the SIB that sets in advance, only visible to advanced long term evolution user equipment (LTE-A UE), only LTE-A UE can read described indication information, and long term evolution user equipment (LTE UE) not can read.
It should be noted that, described LTE UE, refers to the UE with LTE modular working; Described LTE-AUE, refers to the UE with LTE-A modular working, and this UE is compatible LTE modular working mode simultaneously; Described LTE system, can support the access of LTE UE and LTE-A UE, and now LTE-A UE communicates according to the working method of compatible LTE specification; Described LTE-A system, can support the access of LTE UE and LTE-AUE.
Comprise for the indication information of exclusive broadcast message that obtains carrier aggregation system: the carrier aggregation condition information of carrier aggregation system, and for sending the identification information of main member carrier of exclusive broadcast message of carrier aggregation system.UE is by this two parts information, thus the correct exclusive broadcast message of reception carrier paradigmatic system.
The exclusive broadcast message of carrier aggregation system can send by the extend information territory of system information block SIB, also can send by the SIB setting in advance separately.Described exclusive broadcast message is also only to have LTE-AUE can read, and LTE UE not can read.
So-called separately by the SIB transmission setting in advance, adopt separately SIB block of information newly-increased outside the SIB1～SIB7 in LTE system to send, instead of adopt the extend information territory in SIB1～SIB7 to send.
Non-extend information territory in SIB1～SIB7, can be used for sending the basic broadcast message of carrier aggregation system.
Correspondingly, a kind of broadcast message method of reseptance that the embodiment of the present invention provides comprises: subscriber equipment is by the basic broadcast message of each member carrier reception carrier paradigmatic system in carrier aggregation system; And by the exclusive broadcast message of predefined main member carrier reception carrier paradigmatic system in carrier aggregation system, wherein, the number of main member carrier is less than the number of all member carriers that comprise in carrier aggregation system.
LTE-A UE reads the indication information for obtaining exclusive broadcast message by each member carrier in carrier aggregation system, obtains exclusive broadcast message by this indication information from main member carrier.
And LTE-A UE first reads carrier aggregation condition information, then read the identification information of main member carrier.
Provide concrete explaining below.
For essential basic broadcast message in existing LTE Release 8 systems, on each member carrier, send, to ensure that the flow process that all LTE UE can specify according to current Release 8 agreements obtains system broadcast information, ensure backwards compatibility.
Basic broadcast message described in the embodiment of the present invention can be all broadcast messages of LTE Release 8 normalized definitions.For example: the information such as up/down row system bandwidth, up frequency, the configuration of uplink cycle prefix length, the configuration of TDD up/down row, the configuration of TDD special subframe.
In the embodiment of the present invention, for basic broadcast message, can represent with LTE BCH.
Exclusive broadcast message described in the embodiment of the present invention, it is newly-increased (or expansion) broadcast message of LTE-A system, such as antenna configuration information, up-link carrier aggregation information etc., on its main member carrier only setting in advance in LTE-A system, send, this main member carrier can be a member carrier, also can be multiple member carriers, but needn't on all member carriers, all send, thereby reduce system resource overhead.
Exclusive broadcast message described in the embodiment of the present invention, the cell broadcast information LTE-AUE being sent, LTE UE does not need this information.This exclusive broadcast message can represent with E-BCH.
Suppose that carrier aggregation system comprises 5 member carriers, numbering respectively from 1 to 5, and to preset member carrier 3 be main member carrier, as shown in Figure 5, LTE BCH broadcasts on all member carriers, and only broadcast on member carrier 3 therein of E-BCH.
Thereby the subscriber equipment of all LTE-A systems can read LTE BCH in the time of initial access on any one member carrier, and LTE-A UE can read E-BCH on the main member carrier of this LTE-A system.
Because E-BCH only sends on main member carrier, and LTE-A UE may access any one member carrier and read LTE BCH in the time initially accessing, therefore need to notify LTE-A UE to read E-BCH on concrete which or which member carrier, that is to say that LTE-A UE will read the E-BCH on the main member carrier of LTE-A system, also needs to obtain the indication information for obtaining E-BCH.
In the embodiment of the present invention, will notify to the mode of LTE-A UE and have two kinds for the indication information that obtains E-BCH: a kind of is to carry the indication information for obtaining E-BCH by the extend information territory of MIB or SIB; Another be by set in advance another independently SIB carry the indication information for obtaining E-BCH.
In the time that the indication information for obtaining E-BCH is carried in the extend information territory by MIB or SIB, need to carry out two-part expansion, as shown in Figure 6, the first expansion is for carrying the carrier aggregation condition information of current carrier aggregation system, can comprise the number of all member carriers in LTE-A system, the numbering of each member carrier in system, the bandwidth information of each member carrier and/or the frequency point information of each member carrier etc.; The second expansion is used for the positional information of the transmission resource of the E-BCH that carries LTE-A system, this positional information at least comprises the numbering (i.e. mark) of the member carrier at E-BCH place, also can further comprise this member carrier concrete time domain, frequency domain position etc.
The information that the first expansion carries is the correctly access carrier paradigmatic system of UE (comprising LTE-A UE and LTE UE) in order to make LTE-A system.In the MIB carrying due to the member carrier of existing LTE system, indicate the downlink bandwidth of this carrier wave, the first expansion needs the member carrier number in extra instruction LTE-A system so, the numbering of each member carrier in system, and the bandwidth of other each member carriers etc., can correct addressing while making UE receive control signal on other member carriers and data to physical resource position.
The information that the second expansion carries, be numbered example with the member carrier at instruction E-BCH place, if participating in the number of the member carrier of polymerization by the information instruction in the first expansion is M,, in the situation that main member carrier is a member carrier, can adopt
individual bit represents the carrier index of the member carrier (i.e. main member carrier) of the current E-BCH of carrying information.In the situation that main member carrier is a member carrier or multiple member carrier, can use M bit, adopting bitmap mode to indicate which or which member carrier is the member carrier (i.e. main member carrier) that carries E-BCH, for example: in the time of M=5, the indication information that the second expansion carries can be " 10001 ", represents that member carrier 1 and member carrier 5 are main member carrier.
The information that LTE-A UE carries by above-mentioned the first expansion and the second expansion, determines the particular location of the main member carrier at E-BCH place, thereby read E-BCH on this main member carrier.
Now E-BCH also can carry by the extend information territory of MIB or SIB; Or by set in advance another independently SIB carry.
For example: the indication information that the first expansion is comprised is expanded in the mib information piece of LTE system, fill the untapped bit (10bits at most) of reserving at present in the MIB of LTE system, now, the indication information that the second expansion comprises can be expanded in the mib information piece of LTE system, takies the remaining mib information position of having filled after the indication information that the first expansion comprises; Or the second expansion also can be expanded in the SIB of LTE system information, a certain SIB information (SIB1～SIB7) of LTE system to be expanded, this expansion only LTE-AUE can be understood.
Now, E-BCH can be arranged on one or more outside existing SIB1～SIB7, and independently only the visible SIB block of information of LTE-A UE (as SIB8) is upper, and sends by main member carrier.In addition, also can be used as expansion and expand among one or more SIB of existing LTE system, suppose that expansion is in SIB X, now X need to meet the following conditions:
If the second expansion in MIB, 1 <=X <=7;
If the second expansion in SIB Y, wherein 1 <=Y <=7, Y <=X <=7.
That is to say, LTE-A UE need to first obtain the indication information in the first expansion, then obtains the indication information in the second expansion, thereby can normally obtain E-BCH.That is to say, the numbering of carrying the SIB of the indication information in the first expansion is less than or equals the numbering of the SIB that carries the indication information in the second expansion.
Again for example: the first expansion is expanded in existing SIB, for example expand the Z at SIB, wherein 1 <=Z <=7, the second expansion can be expanded in SIB Y information, and meets Z <=Y <=7.Now E-BCH can be arranged on one or more the visible SIB block of informations of LTE-A UE only independently outside existing SIB1～SIB7, and sends on main member carrier.Or E-BCH also can be used as expansion and expands among existing SIB X, but need to meet Y <=X <=7.That is to say, the numbering of carrying the SIB of E-BCH is greater than or equals the numbering of the SIB that carries the indication information in the second expansion.
When by set in advance another when independently SIB carries the indication information for obtaining E-BCH, as shown in Figure 7, the indication information that is equivalent to that above-mentioned the first expansion and the second expansion are comprised adopts separately one or more SIB block of information to send, and does not adopt same SIB block of information to send with LTE BCH.
For example: outside the SIB1～SIB7 in existing LTE system, increase the only visible SIB block of information of LTE-AUE newly, for example, be called SIB X, SIB X sends on each member carrier, for carrying the indication information for obtaining E-BCH; And, outside SIB 1～SIB7 in existing LTE system, increase again the only visible SIB block of information of LTE-A UE newly, for example be called SIB Y, SIB Y is only in the upper transmission of main member carrier (can be one or more), be used for carrying E-BCH, be the exclusive broadcast message of LTE-A system, wherein, X <=Y.
In addition, E-BCH is except the exclusive broadcast message that comprises LTE-A system, also may comprise the item of information identical with LTE BCH, in the time that the parameter value carrying in the parameter value carrying in E-BCH corresponding to this item of information LTE BCH corresponding from this item of information is different, LTE-A UE reads after E-BCH, utilize the parameter value in E-BCH to upgrade the corresponding parameter value of same item of information of reading before from LTE BCH, and LTE UE still carry out work according to all system information parameters values of LTE BCH notice.
