Description
Technical field
The present invention relates to the communications field, particularly a kind of configuration application process and device of PDCCH resource.
Background technology
At LTE (Long Term Evolution; Long Term Evolution) in Rel 8 system; Blind Detecting need be carried out simultaneously to the PDCCH (physical downlink control channel, Physical Downlink Control Channel) in the exclusive search volume of common search space and UE in the terminal.In the common search space, the CCE of PDCCH (Control Channel Element, control channel element) polymerization grade can only be 4 and 8, and is corresponding, under every kind of CCE polymerization grade, needs the number of the candidate PDCCH of blind check to be respectively 4 and 2; And in the exclusive search volume of UE, the CCE polymerization grade of PDCCH can be 1,2,4,8; And under every kind of CCE polymerization grade, it is different needing the number of the candidate PDCCH of blind check, in the 9.1.1 of 3GPPTS36.213, has provided description, specifically as shown in table 1:
Table 1

(the candidate PDCCH in the exclusive control of the UE space)
As shown in table 1, corresponding to [1,2,4,8] four kinds of CCE polymerization grades, the number of the candidate PDCCH in the exclusive search volume of UE can be described as [6,6,2,2] respectively, and the number of the candidate PDCCH in the common search space can be described as [4,2] respectively; Generally, the corresponding a kind of transmission mode of each number needs two kinds of DCI of blind check (Downlink Control Information) form for every kind of transmission mode, thus, can find out that the terminal among the LTE needs the number of times of blind check to be: 2* [6+6+2+2+4+2]=44.Wherein the definition of the exclusive search volume of UE is shown in following formula:

Consult shown in Figure 1; And for LTE (LTE-Advanced) system that strengthens, for supporting the system bandwidth wideer than LTE system (for example, 100MHz); Need to couple together use, dual mode specifically arranged through resource with a plurality of LTE carrier waves (claiming member carrier again):
A plurality of continuous LTE carrier waves are carried out polymerization, for LTE-A provides bigger transmission bandwidth.
A plurality of discontinuous LTE carrier waves are carried out polymerization, for LTE-A provides bigger transmission bandwidth.
Consult Fig. 2 A, Fig. 2 B and shown in Figure 3; The research of standardization body tendency does at present; For the common recognition of carrier aggregation system design is that design on each carrier wave keeps consistent as far as possible with LTE Rel 8, thus the terminal of assurance LTE Rel 8 systems can be on each member carrier operate as normal.
In LTE-A system (being LTE Rel-10), the controlling schemes of PDCCH mainly contains following two kinds of patterns:
Pattern 1: independent scheduling, promptly each carrier wave is independently dispatched, and does not support to stride carrier dispatching, and in this case, among the definition of the PDCCH search volume of each carrier wave and the LTE R8 is consistent; Specifically shown in Fig. 2 A.
Pattern 2: stride carrier dispatching, promptly can pass through other carrier waves of carrier dispatching, specifically shown in Fig. 2 B.
Stride under the carrier dispatching situation what pattern 2 was described; Consider the complexity of PDCCH design; The flexibility of scheduling; The complexity of PDCCH blind check, and the influence that brings under the asymmetric state of carrier aggregation of up-downgoing, the incidence relation of setting between PDCCH CC (Physical Downlink Control Channel member carrier) and the PDSCH/PUSCH CC (Physical Downlink Shared Channel and/or Physical Uplink Shared Channel member carrier) is: the angle from the terminal; Satisfying a PDSCH/PUSCH CC can only dispatch through a PDCCH CC, specifically as shown in Figure 3.
Wherein, different PDSCH/PUSCH CC have PDCCH search volume separately, and the number of its candidate PDCCH when CCE polymerization grade is [1,2,4,8] is [6,6,2,2] respectively, and the definition of its search volume is following:
Each is the mode of the placement employing cascade of search volume independently, and the position of its CCE starting point produces according to a hash function, and it defines as follows:
Y
k＝(A·Y
k-1)mod?D

RNTI≠0，A＝39827，D＝65537
Wherein,
Be illustrated in that the CCE polymerization grade for PDSCH/PUSCH CC n is the PDCCH search volume of L among the subframe K, n=1,2 ..., (N-1), wherein N is the number of the member carrier of polymerization, M
(L)Be the number of the candidate PDCCH when the polymerization grade is L, m=0 wherein ..., M
(L)-1, i=0 ..., L-1, N
CCE, kWhat represent is the number of the CCE in the k sub-frame.
Simultaneously, the search volume between the different CC is when a PDCCH CC is inner, if the bit of DCI form is identical, different CC also can share the inner search volume of PDCCH CC.
Generally, the CA of UE (Carrier aggregation, carrier aggregation) polymerizing power is by the configuration of UE self decision, can directly confirm the PDCCH blind check number of times that UE can maximum support according to the CA polymerizing power of UE, and is specific as follows:
The descending CA polymerizing power of supposing UE is a N member carrier, and the up CA polymerizing power of UE is a K member carrier, in Rel-10; Up K the carrier wave of UE always with a descending N member carrier in K member carrier the incidence relation of fixing SIB2 (system information block 2) indication is arranged, these have the uplink member carrier of fixed correlation relation is identical with carrier index in the DCI information of downlink member carrier when dispatching, and the search volume of its PDCCH also is identical; Therefore, the up CA polymerizing power of UE is smaller or equal to the descending CA polymerizing power of UE, K≤N; In the PDCCH search volume of each CC correspondence of UE polymerization, CCE polymerization grade is [1,2; 4,8] number of corresponding candidate PDCCH difference [6,6 time; 2,2]; In this case, the maximum PDCCH blind check number of times calculating of UE support can be following:
If UE does not support UL-MIMO (uplink multi-users input and output), on all candidate PDCCH candidate, need two kinds of DCI forms of blind check so, so its maximum blind check number of times of supporting is:
Common search space: 2* (4+2)=12
The search volume that UE is exclusive: N*2* (6+6+2+2)
Total blind check number of times: 12+32*N
If UE supports UL-MIMO, need extra blind check to be used for the DCI format4 of UL-MIMO transmission so above that in the PUSCH CC corresponding search space of going, therefore, the maximum blind check number of times of supporting of UE is:
Common search space: 2* (4+2)=12
The search volume that UE is exclusive: N*2* (6+6+2+2)+k* (6+6+2+2)
Total blind check number of times: 12+32*N+16*K
At the PDSCH/PUSCH of UE polymerization CC (promptly being used for transmitting the member carrier of PDSCH/PUSCH); Usually have only a CC to be defined as Primary CC (abbreviation main carrier); Primary CC is by base station selected and dispose to UE through the RRC signaling, and the Primary CC of different UEs can be different.The major function that Primary CC binds is following:
Have only Primary CC to dispose PUCCH (Physical uplink control channel, Physical Uplink Control Channel), be used to transmit CQI/ACK/SR;
Descending UL timing reference (UL timing reference) carrier wave that inserts at random that can be used as of Primary CC;
Primary CC can be used as the pathloss reference (path loss reference) of Primary CC and CC;
Have only on the Primary CC and can carry out RACH;
Have only on the Primary CC and can dispose the SPS resource;
Have only RLF (Radio link falure, Radio Link Failure) takes place on the Primary CC, think that just RLF takes place at the terminal.
This shows, in the PDCCH search volume that in the LTE-A system, defines, regardless of the CA polymerizing power of UE; UE always with in the PDSCH/PUSCH CC set comprises the relevant of CC with the size of the PDCCH search volume of network side agreement; Do not make full use of the maximum blind check number of times that UE can support, along with the development of intelligent terminal technology, the blind check ability of UE strengthens day by day; If also come search volume, then can cause not matching of UE ability and PDCCH resource for UE configuration PDCCH according to traditional approach; Especially under a fairly large number of situation of UE,, can cause the obstruction of PDCCH, reduce the throughput of system, thereby influence systematic function according to traditional approach configuration PDCCH search volume.

Based on technique scheme, to consult shown in Figure 6ly, in the embodiment of the invention, the base station is following to the detailed process of UE configuration and Using P DCCH resource (being the PDCCH search volume):
Step 600: the base station receives the CA ability information that UE reports.
In the present embodiment, the CA ability information that UE reports, the maximum PDCCH blind check number of times of having indicated UE to support; The CA ability information can be defined as N=max (L; K) individual member carrier, L are the ability of the descending polymerization of UE, descending carrier number that promptly can polymerization; K is the ability of the up polymerization of UE, up-link carrier number that promptly can polymerization.
Be specially:
In the corresponding PDCCH search volume of each CC of polymerization, the number of corresponding candidate PDCCH difference [6,6,2,2] when CCE polymerization grade is [1,2,4,8];
If UE does not support UL-MIMO, on all candidate PDCCH, need two kinds of DCI forms of blind check so, so its maximum PDCCH blind check number of times of supporting is:
Common search space: 2* (4+2)=12
The search volume that UE is exclusive: N*2* (6+6+2+2)
Total blind check number of times (being the maximum PDCCH blind check number of times that UE can support): 12+32*N
If UE supports UL-MIMO, need extra blind check to be used for the DCI format4 of UL-MIMO transmission so above that in the PUSCH CC corresponding search space of going, therefore, the maximum PDCCH blind check number of times of supporting of UE is:
Common search space: 2* (4+2)=12;
The search volume that UE is exclusive: N*2* (6+6+2+2)+k* (6+6+2+2);
Total blind check number of times (being the maximum PDCCH blind check number of times that UE can support): 12+32*N+16*K
Step 610: the member carrier collection to the UE configuration is confirmed in the base station; As, local PDSCH/PUSCH CC set to the UE configuration is confirmed in the base station.
In the practical application, the base station also need be with the configuration information notice UE of above-mentioned PDSCH/PUSCH CC set, so that make UE also can confirm the PDCCH resource that self obtains according to this information.
Step 620: the base station is according to member carrier collection that disposes to UE and the CA ability information of UE; Confirm respectively in the member carrier collection to the UE configuration; In the PDCCH search volume of each member carrier correspondence; The number of candidate PDCCH under each CCE polymerization grade makes the PDCCH blind check total degree of UE in the corresponding PDCCH search volume of each member carrier be no more than the maximum PDCCH blind check number of times that UE can support.
In step 620; When the base station basis is directed against the member carrier collection of UE configuration and the CA ability information of UE, confirm in the member carrier collection, in the PDCCH search volume of any member carrier correspondence; During the number of the candidate PDCCH under each CCE polymerization grade; At first, according to the member carrier collection of UE configuration and the CA ability information of UE, confirm the PDCCH search volume configuration relevant parameter that above-mentioned any member carrier is corresponding; Then, based on the mapping relations of formulating in the existing standard agreement (like the 9.1.1 of 3GPP TS36.213), confirm that the corresponding PDCCH of above-mentioned any member carrier explores in the space number of initial candidate PDCCH under each CCE polymerization grade; At last; Calculate the product of the number of candidate PDCCH initial under above-mentioned PDCCH search volume configuration relevant parameter and each the CCE polymerization grade respectively; And with in the PDCCH search volume of result of calculation as above-mentioned any member carrier correspondence, the number of the candidate PDCCH under each CCE polymerization grade.
Can infer thus and obtain; In member carrier collection to the UE configuration; The PDCCH blind check total degree=UE of UE in the corresponding PDCCH search volume of each member carrier at the PDCCH in common search space blind check total degree+UE at the PDCCH in exclusive space blind check total degree; Wherein, UE needs DCI form number (generally value the is 2) * (the number sum * PDCCH search volume configuration relevant parameter M of the candidate PDCCH in the corresponding PDCCH search volume of the number sum * PDCCH search volume configuration relevant parameter 2+...... carrier wave M of the candidate PDCCH in the corresponding PDCCH search volume of the number sum * PDCCH search volume configuration relevant parameter 1+ carrier wave 2 of the candidate PDCCH in the corresponding PDCCH search volume of carrier wave 1 under each CCE polymerization grade under each CCE polymerization grade under each CCE polymerization grade) of blind check at the PDCCH in exclusive space blind check total degree=UE.
Wherein, M is the number of member carrier in the PDSCH/PUSCH CC set; Can adopt following mode to confirm: the number of supposing the member carrier in the PDSCH CC set is P; The number of the member carrier in the PUSCH CC set is Q, and the incidence relation of the SIB2 that Q1 PUSCH CC and the PDSCHCC PDSCH CC in gathering do not have to fix is arranged in Q PUSCH CC.M=P+Q1 member carrier so.
Wherein, the value of the PDCCH search volume configuration relevant parameter that each carrier wave is corresponding can be identical, also can be different, and in the present embodiment, former a kind of situation is that example is introduced.The physical record mode is following:
Suppose that the CA ability information that UE reports shows that UE supports N member carrier of polymerization; Simultaneously, suppose that the carrier number that comprises in the PDSCH/PUSCH CC set is M, M≤N is designated as Mi with PDCCH search volume configuration relevant parameter, i=1, and 2 ..., M 1≤M
i≤N, and
Any member carrier during then PDSCH/PUSCHCC gathers, i.e. CCE polymerization grade [1,2,4 in the PDCCH search volume of i PDSCH/PUSCH CC correspondence; 8] number of corresponding candidate PDCCH is respectively Mi* [6,6,2,2]; I.e. [Mi*6, Mi*6, Mi*2, Mi*2]; So, actual PDCCH blind check total degree=12+2* of UE (M1* (6+6+2+2)+... Mi* (6+6+2+2)+... MM* (6+6+2+2)=12+32* (M1+......Mi+......MM).
On the other hand; In the present embodiment; When execution in step 620, the base station is according to above-mentioned PDSCH/PUSCH CC set and the CA ability information that UE reports, when confirming that the corresponding PDCCH search volume of above-mentioned any member carrier disposes relevant parameter (being Mi); The operation rule that can adopt has multiple; For example,
wherein
As
when value is integer; The value of the PDCCH search volume configuration relevant parameter that the base station is corresponding with each PDSCH/PUSCH CC all is set to
like this; The value of the Mi that any PDSCH/PUSCH CC is corresponding all is identical, i.e.
As
when value is not integer; Value of rounding that initial value all is set to
of the PDCCH search volume configuration relevant parameter that the base station is corresponding with each PDSCH/PUSCH CC earlier; Promptly
is again based on the distribution priority of appointment; Remainder with
is according to preset allocation unit (being also referred to as granularity); Distribute to corresponding PDSCH/PUSCH CC successively; Thereby the initial value to each self-corresponding PDCCH search volume configuration relevant parameter of these PDSCH/PUSCH CC is made further adjustment; Obtain the final value of PDCCH search volume configuration relevant parameter; Wherein, the distribution priority of Primary CC is the highest; For example; The initial value of the PDCCH search volume configuration relevant parameter that the base station is corresponding with each PDSCH/PUSCH CC earlier all is set to
then; Remainder with
; With 1 is that the granularity priority allocation is given PrimaryCC; If residue is arranged; To remain numerical value again is granularity with 1; Based on the carrier index of other PDSCH/PUSCH CC order (by CIF (carrier indicator field, carrier wave indication information territory) indication, can from size to; Also can be from small to large) distribute to corresponding PDSCH/PUSCH CC, be adjusted into final value with the initial value of the PDCCH search volume relevant configured parameter that each PDSCH/PUSCH CC is corresponding; Like this; The final value of the PDCCH search volume relevant configured parameter that any PDSCH/PUSCH CC is corresponding; Whether be Primary CC or can obtain i.e.
according to it according to its carrier index
On the other hand, in the above-described embodiments, the CCE original position of the PDCCH search volume under every kind of CCE polymerization grade of UE is continued to use existing definition.
Step 630: the base station selects at least one candidate PDCCH to send DCI to UE in fixed candidate PDCCH.
In the above-described embodiments; Behind the PDCCH search volume configuration relevant parameter that each member carrier is corresponding in having confirmed PDSCH/PUSCH CC set of base station; Can adopt high-level signaling (as; The RRC signaling) each member carrier is corresponding PDCCH search volume configuration relevant parameter is notified to UE; Also can make UE adopt and calculate the PDCCH search volume configuration relevant parameter that each member carrier is corresponding in the PDSCH/PUSCH CC set behind the PDSCH/PUSCH CC set notice UE with the identical operation rule of base station agreement.
Certainly, the base station also can directly be notified the number of the candidate PDCCH under each polymerization grade that each member carrier is corresponding in the PDSCH/PUSCH CC set of finally confirming to UE through high-level signaling, repeats no more at this.
Corresponding to the foregoing description, to consult shown in Figure 7ly, in the embodiment of the invention, UE is following according to the detailed process of base station indication configuration and Using P DCCH resource:
Step 700:UE receives the member carrier collection information that network side sends; As, UE confirms that the base station is the PDSCH/PUSCH CC set of UE configuration.
Step 710:UE is based on member carrier collection information that obtains and local CA ability; Confirm in the corresponding member carrier collection respectively; In the PDCCH search volume of each member carrier correspondence; The number of candidate PDCCH under each control channel Elements C CE polymerization grade makes local PDCCH blind check total degree in the corresponding PDCCH search volume of each member carrier be no more than the local maximum PDCCH blind check number of times of supporting.
In execution in step 710 processes; When the CA ability of UE, confirm in the corresponding member carrier collection, in the PDCCH search volume of any member carrier correspondence according to the member carrier collection information that obtains and this locality; During the number of the candidate PDCCH under each CCE polymerization grade; At first, according to above-mentioned member carrier collection and local CA ability, confirm the corresponding PDCCH search volume relevant configured parameter of above-mentioned any member carrier; Then, based on the mapping relations of formulating in the existing standard agreement, confirm that the corresponding PDCCH of above-mentioned any member carrier explores in the space number of initial candidate PDCCH under each CCE polymerization grade; At last; Calculate the product of the number of candidate PDCCH initial under above-mentioned PDCCH search volume configuration relevant parameter and each the CCE polymerization grade respectively; In the PDCCH search volume of result of calculation as above-mentioned any member carrier correspondence, the number of the candidate PDCCH under each CCE polymerization grade.
Wherein, the value of the PDCCH search volume configuration relevant parameter that each carrier wave is corresponding can be identical, also can be different, and in the present embodiment, former a kind of situation is that example is introduced.The same base station of its recording mode, specific as follows:
The CA ability of supposing UE shows that UE supports N member carrier of polymerization; Simultaneously, suppose that the carrier number that comprises in the PDSCH/PUSCH CC set is M, M≤N is designated as Mi with PDCCH search volume configuration relevant parameter, i=1, and 2 ..., M 1≤M
i≤N, and
Any member carrier during then PDSCH/PUSCHCC gathers, i.e. CCE polymerization grade [1,2,4 in the PDCCH search volume of i PDSCH/PUSCH CC correspondence; 8] number of corresponding candidate PDCCH is respectively Mi* [6,6,2,2]; I.e. [Mi*6, Mi*6, Mi*2, Mi*2]; So, actual PDCCH blind check total degree=12+2* of UE (M1* (6+6+2+2)+... Mi* (6+6+2+2)+... MM* (6+6+2+2)=12+32* (M1+......Mi+......MM).
In the above-described embodiments; UE is gathering and local CA ability based on the PDSCH/PUSCH CC that obtains; When confirming that the corresponding PDCCH search volume of above-mentioned any member carrier disposes relevant parameter; The indication that can issue through high-level signaling according to the base station; Confirm to dispose relevant parameter to the PDCCH search volume that above-mentioned any member carrier is provided with, this PDCCH search volume configuration relevant parameter is that calculate based on PDSCH/PUSCH CC set that issues to UE and the CA ability of UE the base station; Perhaps; Member carrier number M in the PDSCH/PUSCH CC set that UE also can confirm earlier to obtain; And the member carrier number N of confirming this locality support polymerization that local CA ability characterizes, then, adopt operation rule again with the base station agreement; Based on member carrier number M of knowing and the local member carrier number N of supporting polymerization, calculate the corresponding PDCCH search volume configuration relevant parameter (being Mi) of above-mentioned any member carrier.When calculating the PDCCH search volume relevant configured parameter of i PDSCH/PUSCH correspondence; The operation rule that UE can adopt has multiple; For example;
wherein
As
when value is integer; The value of the PDCCH search volume configuration relevant parameter that UE is corresponding with each PDSCH/PUSCH CC all is set to
like this; The value of the Mi that any PDSCH/PUSCH CC is corresponding all is identical, i.e.
As
