Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Embodiments of the invention provide a kind of indicating means of member carrier, are applied to a plurality of member carriers are carried out in the scene of polymerization, with realization the member carrier at the physical resource place of terminal scheduling are indicated.As shown in Figure 3, the method comprises:
Step s301, base station in the DCI that sends to terminal, add the indication of the physical resource place member carrier of terminal scheduling according to the member carrier at the physical resource place of terminal scheduling in a plurality of member carriers.
Step s302, base station send DCI by PDCCH to terminal.
Below in conjunction with concrete execution mode member carrier indicating means of the present invention is described in detail.
When using the indicating means of the member carrier that embodiments of the invention provide, for having set up the terminal that RRC is connected with the base station, indicate the member carrier at the physical resource place of terminal scheduling by carry carrier index indication information territory in DCI the base station.The DCI form that then uses among the PDCCH comprises following two kinds: (1) comprises the DCI in carrier index indication information territory, and is different according to the number of bits in carrier index indication information territory in this situation, DCI meeting respective change; (2) do not comprise the DCI in carrier index indication information territory, this situation is identical with the form of DCI in the prior art.
Do not set up RRC (Radio Resource Control with the base station in terminal, Radio Resource control) before the connection, terminal is only monitored a member carrier in the IDLE state, and use and not comprise that the DCI form in carrier index indication information territory carries out blind check to PDCCH, this processes same prior art.Only monitor a member carrier when terminal initial enters the RRC connection status, and use the DCI form that does not comprise carrier index indication territory that PDCCH is carried out blind check, this processes same prior art.
Terminal is that to the reason that PDCCH carries out blind check what terminal can't be known current DCI transmission is the information of what format, and the information of oneself need also not knowing is in which position.
The information that generally includes among the DCI comprises
UL Grant(format 0)
DL Assignment(format 1)
Paging(format 1c)
RACH Response(format 1c)
System Information(format 1c)
MIMO Downlink Assignment(format 2)
Power Control Command(format 3)
…
More than can be referring to 3GPP TS 36.212 documents about the explanation of format among the DCI 0, format 1, format 1c, format 2 and format 3.
Terminal knows that according to current state self is current in what information of expectation, for example:
Terminal is when the IDLE state, and the information of expectation is Paging and System Information;
After terminal is initiated Random Access, expectation be RACH Response;
Terminal when having upstream data etc. to be sent, expectation UL Grant; Etc..
For different expectation information, terminal with corresponding X-RNTI go with DCI in CCE (ControlChannel Elements, control channel) information is CRC (Cyclic Redundancy Check, cyclic redundancy check (CRC) code) verification, if CRC check success, UE just knows that this CCE information is oneself needs so, also knows corresponding DCI format and modulation system, thereby further solves the DCI content.I.e. so-called " blind check " process.
Consider some information such as paging, SI, RACH response are that all UE will go to monitor, and some are arranged then is with the relevant as above descending scheduling instruction of particular UE.In order to improve the blind check efficient of UE, in the prior art CCE among the DCI has been divided CCE public search space (Common Search Space) and the specific search volume of UE (UE-Specific Search Space), searched in different spaces for different information.Wherein public search space is top 16 CCE.The original position of the specific search volume of UE is according to 3GPP TS 36.213 documents.
For the information of some format, a CCE is not carrying, may need a plurality of CCE in addition, so agreement stipulated so-called CCE Aggregation Level (CCE polymerization level), and value is 1,2,4,8.For example only have 4,8 two kinds of values for the information A ggregation Level that is positioned in the public space.UE does not generally know use the sort of Aggregation Level, so UE need to attempt all possibilities one time.For example for Common Search Space, UE needs to search for by Aggregation Level=4 and Aggregation Level=8 respectively.When pressing the AL=4 search, 16 CCE need to search for 4 times, and 4 Control Channel Candidates are namely arranged; When pressing the AL=8 search, 16 CCE need to search for 2 times, and 2 CCH Candidates are namely arranged; So for public space one total 4+2=6 CCH Candidates.For UE Specific, corresponding to Aggregation Level=1,2,4,8 have respectively 6,6,2,2 CCH Candidates, and one has 16.
When terminal was in the RRC connection status, the indicating means of the member carrier that provides in the embodiments of the invention may further comprise the steps as shown in Figure 4:
The set of the member carrier that step s401, base station notification terminal activate, affirmation terminal are known and need to be carried out blind check to the DCI that the physical resource place member carrier of carried terminal scheduling is indicated.
This notice can send by the mode of RRC signaling or L1/L2 signaling, and the set of the member carrier that wherein activates can represent by modes such as Bitmap (bitmap).By this notice, the member carrier that terminal can be known all member carriers that carrier aggregation relates to and can be used for the activation of professional transmission.
Concrete affirmation mode includes but not limited to:
The RRC signaling of the set of the member carrier polymerization that (1) activates for this notification terminal or the signaling mechanism that the L1/L2 signaling adopts band to confirm are namely introduced terminal to the feedback of RRC signaling or L1/L2 signaling.Terminal is waited for the DCI of the transmission of base station after this RRC signaling or L1/L2 signaling are fed back.After the base station received the feedback of terminal to this RRC signaling or L1/L2 signaling, the affirmation terminal was known and need to be carried out blind check to the DCI that the physical resource place member carrier of carried terminal scheduling is indicated.
(2) mode by agreement agreement or obviously indication clearly this signaling in the entry-into-force time of base station and terminal.For the mode by the agreement agreement, can set a default time, after the set of base station by the member carrier polymerization of the mode notification terminal activation of RRC signaling or L1/L2 signaling, after having passed through this default time, base station affirmation terminal is known and need to be carried out blind check to the DCI that the physical resource place member carrier of carried terminal scheduling is indicated.For the mode by obviously indicating, can arrange one comes into force the time, this entry-into-force time after the set of the member carrier polymerization that the mode notification terminal when the base station by RRC signaling or L1/L2 signaling activates is when arriving, and the base station is confirmed that terminal is known and need to be carried out blind check to the DCI of the physical resource place member carrier indication of carried terminal scheduling.Above-mentioned default time and entry-into-force time can stipulate in agreement, or send to terminal by the base station by modes such as broadcasting, so that base station and terminal can both be known this default time and entry-into-force time.
Step s402, base station obtain in DCI the indicating mode that the member carrier at the physical resource place of terminal scheduling is indicated.
The indicating mode that embodiments of the invention provide includes but not limited to following three kinds:
Mode 1: based on the carrier index indication of Cell-specific (based on the residential quarter), when the member carrier number that can carry out carrier aggregation that disposes has been determined, can be identified for accordingly the number of bits of the information field of indication carrier wave numbering in the residential quarter.In the embodiments of the invention, the relation between the number of bits in up/down row member carrier number and carrier index indication information territory is as shown in table 1 below:
Relation between the number of bits in table 1. member carrier number and carrier index indication information territory
The member carrier number The number of bits (bit) in carrier index indication information territory Explanation
1 0 Do not need the carrier index indication
2 1 0: the member carrier 1 of member carrier numbering 0: the member carrier of member carrier numbering 1
3 2 00: the member carrier 01 of member carrier numbering 0: the member carrier 10 of member carrier numbering 1: the member carrier 11 of member carrier numbering 2: reservation bit
4 2 00: the member carrier 01 of member carrier numbering 0: the member carrier 10 of member carrier numbering 1: the member carrier 11 of member carrier numbering 2: the member carrier of member carrier numbering 3
5 3 000: the member carrier 001 of member carrier numbering 0: the member carrier 010 of member carrier numbering 1: the member carrier 011 of member carrier numbering 2: the member carrier 100 of member carrier numbering 3: the member carrier 101 of member carrier numbering 4: reservation bit 110: reservation bit 111: reservation bit
Be understandable that, can further expand according to the method his-and-hers watches 1 in the table 1 for more member carrier number, so that different member carrier (Component Carrier, CC) number is indicated.For this extending method, be not repeated in this description at this.
The number of bits in carrier index indication information territory is identical among all PDCCH.In the manner, the indication of carrier index is the indication of the member carrier numbering of physics.When the number of the member carrier that for example comprises in the LTE-A system is 6, the member carrier of the corresponding physics of each member carrier be numbered { 0,1,2,3,4,5}.The number of bits that is used to indicate the information field of carrier index among the PDCCH is 3, the member carrier of supposing the physical resource place of terminal scheduling is that physics is numbered 2, then according to table 1, in the PDCCH that sends to terminal, the value in the carrier index indication information territory of DCI is 010 in the base station.
Mode 2: based on the carrier index indication of UE-specific (based on terminal), for the terminal that is in the RRC connection status, in the LTE-A system, be generally the set that its configuration can be carried out the member carrier of professional transmission, this set can be called " member carrier collection of activation ".According to the member carrier number in the member carrier collection of current activation, the indication in carrier index indication information territory is the numbering indication of the member carrier of logic, is used to indicate the carrier index in the current member carrier collection that is in activation.A kind of enforceable method is that the numbering of the member carrier in the member carrier collection that is in activation according to the member carrier of physics sorted, and obtains the numbering of the member carrier of logic.
The number of bits in carrier index indication information territory can be numbered according to the definition in the form 1 equally, and different is that the indication of the carrier index here is a kind of carrier index in logic.For example, the member carrier of the corresponding physics of member carrier that comprises in the LTE-A system be numbered { 0,1,2,3,4,5}, and the number of the member carrier in the current member carrier collection that is in activation is 3, the member carrier of the corresponding physics of member carrier in the member carrier collection of hypothesis activation be numbered { 0,3,5} sorts to the numbering of the member carrier in the member carrier collection that is in activation according to the member carrier of physics, and then the member carrier of the corresponding logic of member carrier in the current member carrier collection that is in activation is numbered { 0,1,2}.Namely in being in the member carrier collection of activation, logical number be 0 member carrier corresponding be that physics is numbered 0 member carrier, logical number be 1 member carrier corresponding be that physics is numbered 3 member carrier, logical number be 2 member carrier corresponding be that physics is numbered 5 member carrier.The member carrier of supposing the physical resource place of terminal scheduling is that physics is numbered 3, and then according to table 1, in the PDCCH that sends to terminal, the number of bits that is used to indicate the information field of carrier index is that the value in the carrier index indication information territory of 2, DCI is 01 in the base station.
In this situation, for UE, UE needs the size of the bit in carrier index indication information territory among the DCI of blind check, is that the number according to the member carrier in the member carrier collection that activates changes.When the number of member carrier changed in the member carrier collection that activates, carrier index indication information territory number of bits changed thereupon, and the variation of carrier index indication information territory number of bits can not increase the complexity that UE carries out the PDCCH blind check.
Mode 3: based on the carrier index configuration of CC specific (based on member carrier), the carrier index indicating length that namely PDCCH comprises in each carrier wave is different.For example, when 3 member carriers carried out polymerization, the PDCCH in carrier wave 1 and the carrier wave 2 all comprised the carrier index indication information of 1bit, and the PDCCH in the carrier wave 3 does not comprise the carrier index indication information.In the case, default base station and UE can distinguish this member carrier that does not carry the carrier index indication information.The member carrier of the corresponding physics of member carrier that for example, comprises in the LTE-A system be numbered { 0,1,2,3,4}, the PDCCH that is numbered 0 member carrier for physics does not carry the carrier index indication information, and default base station and UE can distinguish member carrier 0 and other member carriers.Then the member carrier of the corresponding logic of other member carriers except physics is numbered 0 member carrier is numbered { 0,1,2,3}.The member carrier of supposing the physical resource place of terminal scheduling is that physics is numbered 3, and then according to table 1, in the PDCCH that sends to terminal, the number of bits that is used to indicate the information field of carrier index is that the value in the carrier index indication information territory of 2, DCI is 11 in the base station.
Step s403, base station send by PDCCH DCI to terminal, comprise the indication to the physical resource place member carrier of terminal scheduling among this DCI.
DCI among the PDCCH that step s404, terminal parses receive obtains the member carrier at the physical resource place of scheduling.
Concrete, receive the terminal of signaling among the step s401, the DCI of the physical resource place member carrier indication of carried terminal scheduling is carried out blind check, obtain the member carrier at the physical resource place of dispatching in a plurality of carrier waves.
The indicating means of the above-mentioned member carrier that provides by embodiments of the invention has been realized in multi-carrier aggregation scene the indication to the member carrier at the physical resource place of scheduling.
