Fig. 1 shows the Radio Network System formed according to base station 1 and the user terminal 2 of a specific embodiment of the present invention, wherein, the equipment such as relay station can also be comprised as required between base station 1 and user terminal 2, for convenience of description, eliminate intermediate equipment in Fig. 1, illustrate only base station 1 and user terminal 2.Wherein, user terminal 2 has been configured four component carriers, is respectively CC1, CC2, CC3, CC4, the bandwidth of above-mentioned component carrier can be different according to application scenarios difference, each carrier wave size is separately no more than 20M, and in the present embodiment, four component carrier bandwidth are all configured to 20M.Be appreciated that the component carrier that base station configures for a user terminal is no more than at most 5.
Fig. 2 shows the system flow chart according to a specific embodiment of the present invention.
First, in step S20, base station 1 generates the Resourse Distribute indication information corresponding with each component carrier, this Resourse Distribute indication information is used to indicate the relevant information of the resource distributing to user terminal 2, also be, an all corresponding Resourse Distribute indication information on each component carrier, also be UL grant or DL assignment, UL grant comprises the resource information for user terminal 2 distributes to base station 1 transmit ascending data, the sequence number of starting resource block of such as distributing and the sequence number of the Resource Block of termination, and with the modulation corresponding to the Resource Block of this distribution and coded system.DL assignment comprises the resource information of distributing to user terminal 2 transmitting downlink data for base station 1, the sequence number of starting resource block of such as distributing and the sequence number of the Resource Block of termination, and with the modulation corresponding to the Resource Block of this distribution and coded system.
For downlink data transmission, base station 1 is in order to effectively encapsulate data at transmission block (the Transport Block indicated by Resourse Distribute indication information, TB) in, base station 1 needs to be numbered Resourse Distribute indication information, also be, Gains resources distributes the order identification of indication information, and data to be encapsulated in successively according to pre-defined rule in the transmission block indicated by Resourse Distribute indication information having different order identification by each.Similarly, for the upstream data carrying out user terminal 2, when base station 1 receives multiple transmission block of user terminal 2, base station 1 also needs the order identification knowing each transmission block, and according to pre-defined rule, decapsulation is carried out to the data carrying out user terminal 2.
Therefore, in the step s 21, the order identification of each Resourse Distribute indication information, according to each Resourse Distribute indication information, is determined in base station 1.Below, respectively by two concrete execution modes, the method that base station 1 is numbered for Resourse Distribute indication information is specifically described.
static or semi-static mode
The order identification of each Resourse Distribute indication information corresponding with each component carrier according to the order identification of component carrier, can be determined in base station 1, also, and the numbering of Resourse Distribute indication information.Such as, the Resourse Distribute indication information corresponding to CC1 be numbered Resourse Distribute indication information corresponding to 1, CC2 be numbered Resourse Distribute indication information corresponding to 2, CC3 be numbered Resourse Distribute indication information corresponding to 3, CC4 be numbered 4.In another embodiment, if user terminal 2 has been configured 3 CC, such as be respectively CC1, CC3 and CC5, then with the Resourse Distribute indication information corresponding to CC1 be numbered 1, with the Resourse Distribute indication information corresponding to CC3 be numbered 2, with the Resourse Distribute indication information corresponding to CC5 be numbered 3.Certainly, above-mentioned mode is only example, it will be appreciated by those skilled in the art that, what also can adopt the Resourse Distribute indication information corresponding to CC1 is numbered 4, Resourse Distribute indication information corresponding to CC2 be numbered 3, the numbering being numbered the mode determination Resourse Distribute indication information of 1 being numbered the Resourse Distribute indication information corresponding to 2, CC4 of the Resourse Distribute indication information corresponding to CC3.Because component carrier and Resourse Distribute indication information are one to one, therefore, the order identification can determining Resourse Distribute indication information in this way is easily adopted.
dynamical fashion
Except the mode of the order identification of the above-mentioned order identification information determination Resourse Distribute indication information according to component carrier, can also the character of of resource indicated by Resourse Distribute indication information itself, determine the order identification of Resourse Distribute indication information.
Because comprise the size information of the Resource Block distributing to user terminal and modulation and coded system in Resourse Distribute indication information, therefore, can also sort to Resourse Distribute indication information according to the size of Resource Block and/or modulation and coded system in base station 1.Such as, if time sequence according to the size of Resource Block in base station 1, the Resourse Distribute indication information being designated as user terminal 2 and distributing maximum Resource Block can be numbered 1, the Resourse Distribute indication information being designated as user terminal 2 and distributing time large Resource Block be numbered 2, by that analogy.If the modulation that base station 1 adopts according to Resource Block and coded system are Resourse Distribute indication information when sorting, such as, instruction can adopt the Resourse Distribute indication information of high order modulation coded system to be numbered 1 to Resource Block by base station 1, and exponent number is lower, numbers larger.Such as, 64QAM is adopted for indicating respectively, the Resourse Distribute indication information of 16QAM and QPSK, the Resourse Distribute indication information that instruction modulation and coded system are 64QAM by base station 1 is numbered 1, the Resourse Distribute indication information being 16QAM by instruction modulation and coded system is numbered 2, and the Resourse Distribute indication information being QPSK by instruction modulation and coded system is numbered 3.Wherein, a 64QAM constellation point can carry 6bit information simultaneously, and a 16QAM constellation point can carry 4bit information simultaneously, and a QPSK constellation point can carry 2bit information simultaneously.
Certainly, can sort to Resourse Distribute indication information in conjunction with the resource block size of the distribution in Resourse Distribute indication information and modulation and coded system in base station 1.Such as, first according to resource block size, Resourse Distribute indication information is sorted, if each resource block size indicated by Resourse Distribute indication information is all identical, then sequentially Resourse Distribute indication information is sorted according to the exponent number of modulation and coded system.Certainly, also can first according to modulation and coded system exponent number sequentially, then according to resource block size, Resourse Distribute indication information to be sorted.This dynamic mode, does not need extra signaling consumption, saves bandwidth resources.But, this situation may be there is, namely each resource block size indicated by Resourse Distribute indication information is identical, and the modulation adopted and coded system are also identical, therefore, now need to adopt static or semi-static mode, also namely the order identification of each Resourse Distribute indication information corresponding with each component carrier, according to the order identification of component carrier, is determined in base station 1.
Certainly, base station 1 needs the regular informing user terminal 2 of the order identification by how determining resource allocation information, thus user terminal 2 can be known according to the size information of Resource Block or according to modulation and coded system or both order identification in conjunction with determination resource allocation information.
Because base station 1 generates these resource allocation informations, therefore, the order identification of these Resourse Distribute indication informations is known in base station 1.
Then, in step S22, base station 1 according to the order identification of each Resourse Distribute indication information, user data to be encapsulated in each transmission block corresponding with each Resourse Distribute indication information according to pre-defined rule and to send to user terminal 2.First be described for downlink data.For downlink data, such as, when base station 1 has multiple service needed to send to user terminal 2, each business wherein comprises minimum transmission data volume, this minimum transmission data volume represents the lower limit of the data volume transmitting this business, therefore, this pre-defined rule comprises: the minimum transmission data volume of each business is first all encapsulated in the transmission block indicated by the DL assignment being numbered 1 by base station 1, if this transmission block also has remaining resource, then the remaining data of business the highest for priority are encapsulated in this transmission block again, then, if the transmission block indicated by DL assignment being numbered 1 is occupied full, then the remaining data of business the highest for priority are encapsulated into again in the transmission block indicated by the DL assignment being numbered 2, the like, thus optimize the flow process of priority of logical channels.Certainly, alternatively, this pre-defined rule also can be: the minimum transmission data volume of each business is first all encapsulated in the transmission block indicated by the DL assignment being numbered 4 by base station 1, if this transmission block also has remaining resource, then the remaining data of business the highest for priority are encapsulated in this transmission block again, then, if the transmission block indicated by DL assignment being numbered 4 is occupied full, then the remaining data of business the highest for priority are encapsulated into again in the transmission block indicated by the DL assignment being numbered 3, the like, thus optimize the flow process of priority of logical channels.
Then, in step S23, base station 1 is by Resourse Distribute indication information informing user terminal 2.Base station 1 by Physical Downlink Control Channel (Physical Downlink ControlChannel, PDCCH) by UL grant or DL assignment message informing to user terminal 2.It will be understood by those skilled in the art that there is no obvious precedence between step S22 and step S23.
In another embodiment, base station 1 also needs the order identification of each component carrier, is also CC Index informing user terminal 2, such as, and CC1, CC2, CC3 and CC4.Base station 1 can utilize broadcast channel, such as Physical Downlink Shared Channel (Physical DownlinkShared CHannel, or Physical Broadcast Channel (Physical BroadcastChannel PDSCH), PBCH) this CC index information is sent, or utilize dedicated channel, such as adopt higher layer control messages, such as radio resource control information (Radio Resource Control, RRC) or media access control layer control message transmit.
In another embodiment, the order identification of each component carrier and the corresponding relation between component carrier and frequency are informed to user terminal 2 by base station 1.Base station 1 can utilize broadcast channel, such as Physical Downlink Shared Channel or Physical Broadcast Channel send this CC index information and corresponding relation, or base station 1 utilizes dedicated channel, such as adopt higher layer control messages, such as radio resource control information or media access control layer control message carry out transmission CC index information and corresponding relation.
In step s 24 which, user terminal 2 receives the Resourse Distribute indication information corresponding with each component carrier from base station 1, and this Resourse Distribute indication information is used to indicate the relevant information of the resource distributing to described user terminal.
Then, in step s 25, user terminal 2, according to each Resourse Distribute indication information, determines the order identification of each Resourse Distribute indication information.
Such as, base station 1 sends UL grant message on the DL CC of PDCCH channel, then user terminal is according to this DL CC and system information block 2 (System InformationBlock, SIB2), contain the corresponding relation between up link and down link in this SIB2, user terminal 2 can obtain the component carrier that this UL grant acts on; In addition, when comprising carrier wave instructions field (Carrier Indication Field, CIF) in PDCCH, user terminal 2, according to the information in CIF, also can obtain the component carrier that UL grant in PDCCH or DL assignment acts on.
In addition, user terminal 2 knows the order identification adopting static mode or dynamic mode Gains resources to distribute indication information in advance, such as, which kind of mode base station 1 adopts by high-rise configuration information informing user terminal 2, certainly, adopt static or dynamic mode also can be that system configures in advance, therefore, do not need base station 1 by signaling user terminal 2.
When user terminal 2 knows the mode that employing is static and base station 1 isochronous resources distributes the order identification of indication information, the frequency information of the component carrier of user terminal corresponding to the resource of the distribution in ULgrant or the DL assignment received on PDCCH channel, and obtain CC index information and the mapping relations between CC index and frequency according to from the broadcast channel of base station 1 or dedicated channel, obtain the CC index corresponding with the frequency resource of distributing in UL grant or DLassignment, again because there is certain corresponding relation between CC index and UL grant or DL assignment, therefore, according to CC index, user terminal 1 can determine the order identification of UL grant or DL assignment.Certain CC index can be configured according to different wireless communication systems from the corresponding relation between UL grant or DL assignment order, and base station 1 needs this configuration information prior notice user terminal 2.
When adopting the order identification of dynamic mode determination Resourse Distribute indication information between base station 1 and user terminal 2, also be, now, user terminal 2 has been known and has been adopted according to the size information of Resource Block or according to modulation and coded system or both order identification in conjunction with determination resource allocation information, therefore, correspondingly, user terminal 2 adopts corresponding mode, determines the order identification of Resourse Distribute indication information.The determination mode that this process determined adopts with base station 1 end is consistent, therefore, does not repeat them here.
Then, first for downlink data, the order information of this Resourse Distribute indication information is used to be specifically described to user terminal 2.
In step S26, user terminal 2 carries out decapsulation to what receive from the data in each transmission block of base station 1 according to pre-defined rule according to the order identification of each Resourse Distribute indication information.Such as, user terminal 2 knows that base station 1 is according in the transmission block first business datum be encapsulated in indicated by the minimum DL assignment of numbering, TB1 such as indicated by DL assignment1, and then remaining business datum is encapsulated in the secondary little transmission block indicated by DLassignment of numbering, such as, order in TB2 indicated by DL assignment2 encapsulates business datum, therefore, user terminal 2 is according to this order, decapsulation is carried out to the data in each transmission block, such as, TB1 indicated by first decapsulation DL assignment1, TB2 again indicated by decapsulation DL assignment2.Certainly, the order of above decapsulation is only example, it will be understood by those skilled in the art that for multiple TB, also can decapsulation concurrently, or according to the sequentially decapsulation of other order.If a high level data bag, such as RRC PDU is encapsulated at least two TB respectively, such as, a RRC PDU is segmented in TB1 and TB2, then because user terminal 2 is according to the information in DL assignment, the order of TB1 and TB2 known by the receiver in user terminal 2, therefore, first segmentation (if existence) of last segmentation of TB1 (if existence) and TB2 can be carried out Combined Treatment, to obtain original packet by user terminal 2.Aforesaid way is applicable equally by the situation being encapsulated in plural TB respectively for a RRC PDU.
Above for downlink data to being synchronously described to the order information of Resourse Distribute indication information between base station 1 and user terminal 2, below, for transmitting uplink data to synchronously carrying out brief description to the order information of Resourse Distribute indication information between base station 1 and user terminal 2.In another embodiment, for upstream data, user terminal 2 is according to each Resourse Distribute indication information in step s 25, after determining the order identification of each Resourse Distribute indication information, in step s 27, user data is encapsulated in each transmission block corresponding with each Resourse Distribute indication information according to the order identification of each Resourse Distribute indication information according to pre-defined rule by user terminal 2, the process of this encapsulation and the step S22 of base station 1 end similar, do not repeat them here, then, the transmission block after this encapsulation is sent to base station 1 by user terminal 2.
Then, in step S28, base station 1 is according to the order identification of each Resourse Distribute indication information, carry out decapsulation according to pre-defined rule to the data come in each transmission block of user terminal 2 received.Generate because Resourse Distribute indication information is base station 1, so the order identification of UL grant is known in base station 1, therefore, decapsulation, directly according to this order identification, is carried out to the upstream data carrying out user terminal 2 received in base station 1.
In the above-described embodiment, for convenience of explanation, being first described descending transfer of data, is also step S26; And then transmitting uplink data is described, be also step S27 and step S28.It will be understood by those skilled in the art that do not have obvious sequencing between transmitting uplink data and downlink data transmission, the sequence number of therefore above-mentioned step does not represent sequencing during actual execution.
