Specific embodiment
The preferred embodiment that the present invention will be described in more detail below with reference to accompanying drawings.Although showing the present invention in attached drawing
Preferred embodiment, however, it is to be appreciated that may be realized in various forms the present invention without the embodiment party that should be illustrated here
Formula is limited.On the contrary, thesing embodiments are provided so that the present invention is more thorough and complete, and can will be of the invention
Range is fully disclosed to those skilled in the art.
Fig. 1 shows a kind of for being transmitted in a base station for the polymerization of extensive carrier wave of embodiment according to the present invention
The flow chart of the method 100 of downlink control signaling.Method 100 can for example be held by the serving BS of one or more UE
Row.In the following description, serving BS is known as base station 1, the UE that base station 1 is serviced is known as UE 2.
As shown in fig. 1, method 100 includes step 110, and wherein base station 1 will will carry out extensive carrier wave for UE 2
Multiple carrier waves of polymerization are divided into multiple carrier wave sets.
In current DCI format, CIF field is 3 bits, can at most indicate 8 carrier waves.
It is preferred, therefore, that the number N of the carrier wave set dividedgroupIt can indicate are as follows:
Wherein,Expression rounds up operator.For example, in an example, polyase 13 2 loads are wanted for UE 2
Wave.Therefore the number N of the carrier wave set dividedgroupIt is 4, the carrier wave set divided can be expressed as carrier wave set 0, carrier wave set
1, carrier wave set 2 and carrier wave set 3.If UE 2 needs to polymerize 17 carrier waves, if each group contains up to 5 carrier waves, according to upper
It states formula and rounds up and need points 4 groups, for example carrier wave set 0, carrier wave set 1 and carrier wave set 2 include 5 carrier waves, carrier wave set 3 includes
2 carrier waves.Fig. 2 shows the schematic diagrames of the carrier wave grouping according to the present invention for the polymerization of extensive carrier wave.
However, it will be understood by those skilled in the art that the present invention is not limited thereto.Before reusing current DCI format
It puts, the number of carrier wave for including in each carrier wave set can be any one in 1-8, or different carrier wave sets may include not
With the carrier wave of quantity, hence for above situation, the quantity of the carrier wave set divided can be any of 4 to 32.
Next, base station 1 notifies the incidence relation between the index and carrier wave of the carrier wave set divided in step 120
To UE 2.
In a kind of preferred implementation, base station 1 passes through higher level signaling (such as wireless heterogeneous networks (Radio Resource
Control, RRC) signaling) to UE 2 notify carrier wave set index and carrier wave between incidence relation.Here, the index of carrier wave set
Incidence relation between carrier wave may include the index of all carrier wave sets and which carrier wave is corresponding carrier wave set include.If
Base station 1 needs to configure cross-carrier scheduling for UE 2 simultaneously, and cross-carrier scheduling may be only available in carrier wave set at this time, such as carrying
For wave group 1, when some carrier wave (i.e. SCell) in carrier wave set 1 can other carrier waves in cross-carrier scheduling group, cannot be across load
Wave dispatches the carrier wave in other groups.
In each carrier wave set divided, base station 1 can distribute the sole carrier in the carrier wave set for each carrier wave
Index.For example, base station 1 can be 8 loads in each carrier wave set for the case where above-mentioned each carrier wave set includes 8 carrier waves
Wave distributes a sole carrier index between 0 to 7 respectively.
In addition, base station 1 can also configure cross-carrier scheduling.For example, it is assumed that it is 0 that PCell, which is located at carrier index in carrier wave set 0,
Position at, then PCell can dispatch other 7 carrier waves (SCell) in the carrier wave set 0.
In step 130, base station 1 sends DCI to UE 2 by the PDCCH in multiple carrier wave set, and the CIF in DCI is used for
Indicate the carrier wave being scheduled in the carrier wave set.If there is no CIF in DCI, then it represents that the carrier wave dispatches oneself.
Here, in step 130, the CIF field of 3 bits in current DCI format is reused, to indicate specific carriers
The carrier wave being scheduled in group.
It, can be in the feelings for reusing current downlink control signaling format as far as possible by the above-mentioned steps of method 100
More massive carrier wave is supported to polymerize under condition.However, this grouping mechanism may bring problem to the distribution of PUCCH resource,
The PUCCH resource of difference group may clash.
Specifically, if the quantity of downlink carrier group is greater than UE and can be used to send upload control on PUCCH
(for example, the quantity of the carrier wave set divided is 5, and UE can be used to send uplink control on PUCCH the quantity of the carrier wave of signaling
The quantity of the carrier wave of signaling processed is 2), then the PUCCH for multiple carrier wave sets may to be transmitted on a carrier wave.
For example, using traditional mechanism, in FDD system, for PDSCH indicated by the DCI that is detected in subframe n-4
For transmission, UE should use the PUCCH resource determined by following formula (2), and transmission is for the PDSCH's in subframe n
HARQACK/NACK::
Wherein, nCCEIt is to be used for transmission the number of the first CCE of corresponding DCI distribution (i.e. for constructing the minimum of the DCI
CCE index),It is configured in system information block (SIB) message by base station, the antenna port that p instruction index is p.
In traditional TDD system, PDSCH transmission indicated by the DCI that detects in subframe n-k (k >=4) is come
