Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the invention, is not Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation Property work under the premise of the every other embodiment that is obtained, belong to the scope of protection of the invention.
In order to solve the Parallel Scheduling Algorithm of carrier aggregation in the prior art it cannot be guaranteed that QoS and making full use of In the problem of resource, the embodiment of the present invention, the UE for have activated SCell determines that above-mentioned UE makes respectively The guaranteed qos CC and each non-guaranteed QoS of each radio bearer (Radio Bearer, RB) CC, and determine that each RB guaranteed qos CC and each non-guaranteed QoS CC is currently distributed MinBR, and MABRs of the above-mentioned UE on guaranteed qos CC and each non-guaranteed QoS CC, Further calculate each RB guaranteed qos CC and each non-guaranteed QoS CC minimum transmission number According to amount, and most transmission numbers of the above-mentioned UE on guaranteed qos CC and each non-guaranteed QoS CC According to amount, and then resource allocation is carried out to guaranteed qos CC and each non-guaranteed QoS CC respectively.
The present invention program is described in detail below by specific embodiment, certainly, the present invention is not limited to Following examples.
What deserves to be explained is, it is the introduction carried out by taking downlink business as an example, for upper in the embodiment of the present invention Industry business is identical with downlink business.Differ only in, it is logic channel group that RB is corresponding in uplink service RB minimum bit rate (Minimum in (Logical Channel Group, LCG), downlink business Bit Rate, MinBR) it is corresponding be up LCG PBR.
As shown in fig.1, in the embodiment of the present invention, the idiographic flow of the Method of Scheduling Parallel of carrier aggregation is such as Under：
Step 100：According to default principle, the UE for have activated SCell determines above-mentioned UE respectively Each RB used guaranteed qos CC and each non-guaranteed QoS CC.
In practice, in carrier aggregation, UE serving cell can be divided into PCell and SCell, right respectively PCC and SCC are answered, after it have activated SCell, UE can be with use SCC.
In order in Parallel Scheduling, it is contemplated that UE qos requirement, it is necessary first to determine that UE is used every One RB guarantee QOS CC and each non-guaranteed QoS CC, i.e., by each RB belong to it is many Individual CC is divided, according to default principle, using one of CC as guaranteed qos CC, remaining CC is used as non-guaranteed QoS CC.
Wherein, in the embodiment of the present invention, default principle is not defined, specifically, can use with Lower two kinds of principles：
The first principle：, will be upper based on the corresponding main member carrier PCC of the above-mentioned UE that have activated SCell PCC is stated as above-mentioned UE each RB used guaranteed qos CC, and using other CC as upper State each RB non-guaranteed QoS CC.
Second of principle：The CC that will be determined according to default acceptance algorithm, as above-mentioned UE use it is every One RB guaranteed qos CC, and using other CC as each above-mentioned RB non-guaranteed QoS CC.
Step 110：Pre-configured qos requirement based on above-mentioned UE, calculates each above-mentioned RB respectively The MinBR currently distributed on guaranteed qos CC and each non-guaranteed QoS CC, and above-mentioned UE The AMBR currently distributed on guaranteed qos CC and each non-guaranteed QoS CC.
In practice, UE configures qos requirement by base station after access base station to the UE, or by core net Directly issue the qos requirement of the UE, wherein, in QoS at least including the UE AMBR requirement and The MinBR requirements for each RB that the UE is used, all CC belonged to for each RB will Qos requirement to the UE is distributed on each CC respectively according to certain way.
When performing step 110, it can specifically be divided into two parts and be introduced：
Part I：Each RB is calculated to be taken in guaranteed qos CC and each non-guaranteed QoS CC The MinBR of preceding distribution.
Specifically, it can be realized using Token Bucket Policing and each RB MinBR is controlled.Below with One RB is distributed on guaranteed qos CC and each non-guaranteed QoS CC and said exemplified by MinBR It is bright.
Assuming that MinBRToken is the token number in the current MinBR token buckets of the RB, MinBRTokenccjFor The MinBR token numbers that the RB is currently distributed on CCj, ccj can be the CC of the guaranteed qos of the RB, Or the non-guaranteed QoS of RB CC.By taking two carrier waves as an example, it is ensured that QoS CC are currently distributed MinBR tokens be MinBRTokenQoS_CC, the MinBR tokens that non-guaranteed QoS CC are currently distributed are MinBRTokennon_QoS_CC。
First, MinBRToken is initializedccj, that is, initialize guaranteed qos CC and each non-guaranteed QoS CC On MinBR.Default value on guaranteed qos CC is MinBRTokenQoS_CC=MinBRToken is non- Default value on guaranteed qos CC is MinBRTokennon_QoS_CC=0.
Specifically, in order to meet QoS demand, MinBRToken is initialized based on certain principleccj, example Such as, according to activation SCell different situations, i.e. guaranteed qos CC is PCell, then,
A) SCell situation is activated based on RLC congestions, then is configured to default value；
B) SCell situation is activated based on QoS, then according to ungratified pro rate, QoS will be unsatisfactory for It is required that fraction be assigned on non-guaranteed QoS CC, i.e.,
MinBRTokenQoS_CC=RB actual transfer rates on PCell before activation SCell / MinBRToken, MinBRTokennon_QoS_CC=1-MinBRTokenQoS_CC。
C) purpose based on load balancing activates SCell situation, then the MinBR of qos requirement is whole It is assigned on non-guaranteed QoS CC,
That is MinBRTokenQoS_CC=0, MinBRTokennon_QoS_CC=MinBRToken.
Then, according to the default cycle, each RB is calculated in guaranteed qos CC and each non-guaranteed The MinBR of current distribution on QoS CC, and determine whether each RB calculated in guaranteed qos Whether the MinBR of the current distribution on CC and each non-guaranteed QoS CC meets the pre-configured of UE Qos requirement, when it is determined that being unsatisfactory for, in guaranteed qos CC and each non-guaranteed QoS during to initialization The MinBR currently distributed on CC enters Mobile state adjustment.
Wherein, RQoS_CC_RB(n) it is RB current actual transfer rates on guaranteed qos CC, Rnon_QoS_CC_RB(n) it is RB current actual transfer rates on non-guaranteed QoS CC.
