Description
Technical field
The present invention relates to communication technical field, particularly a kind of detection method and equipment of uplink scheduling instruction.
Background technology
At multi-carrier aggregation system, such as LTE-A (Long Term Evolution Advanced, senior Long Term Evolution) in the system, support the polymerization between the different bandwidth, couple together to make by resource and be used for obtaining higher data rate (between the continuous carrier and the polymerization between the discontinuous carrier wave) a plurality of carrier waves (claiming member carrier again), consider in system, to have a plurality of polymerization carrier waves, may have dispatch command on a plurality of carrier waves for a user at synchronization so.The DCI (Downlink Control Information, Downlink Control Information) that how to solve accurately for the different members carrier wave is the problem that needs are considered, as shown in Figure 1, is the carrier structure schematic diagram of multi-carrier aggregation system in the prior art.
In LTE R10 system, under the situation of multicarrier, the probability of carrier dispatching is striden in introducing, promptly can be by a plurality of PDCCH (the Physical Downlink Control Channel on the member carrier, Physical Downlink Control Channel) dispatch the physical resource of other member carrier, every PDCCH can only dispatch the resource of a member carrier, as shown in Figure 2, for striding the structural representation of carrier dispatching in the prior art, the main advantage of this scheme is:
(1) Tiao Du flexibility is higher
(2) can carry out interference coordination preferably
When carrier dispatching was striden in use, the user was when accepting the dispatch command of base station, and needing to obtain this dispatch command is the information of dispatching which carrier wave.For indication carrier wave scheduling situation, (Carrier IndicationField CIF) is placed on transmission together on the fixed position of DCI to have introduced the carrier wave indication territory of fixing 3 bit lengths (R10 supports the scenes of 5 carrier aggregation at most at present).
In present discussion, determined that in the R10 system system-level up-downgoing carrier aggregation number is symmetrical, the pair relationhip of up-downgoing is notified in SIB2; And can have the situation of asymmetric polymerization from other polymerization aspect of UE level, as shown in Figure 3.
Simultaneously, determined one on/dispatch command of descending carrier can only send from a descending carrier, and if disposed on carrier wave and striden carrier dispatching, must be able to dispatch on this carrier wave so this carrier wave and with the up-link carrier of its pairing.
In realizing process of the present invention, the inventor finds that there is following problem at least in prior art:
The scene of the asymmetric polymerization of back-up system level not in the existing version.The scene of the system-level asymmetric polymerization that may occur for follow-up protocol version, as shown in Figure 4.
In this case, for a UE, there are two if deposit the pairing descending carrier of certain up-link carrier in the carrier wave of its polymerization, as shown in Figure 5.
For situation shown in Figure 5, for up CC4, UE does not know and which carrier wave to separate the uplink scheduling instruction from, thus the problem that can cause confusion.At present also there is not suitable solution at this problem.
