Embodiment
The embodiment of the present invention provides signaling indication method and base station and the terminal in a kind of carrier aggregation system.
In order to make those skilled in the art person understand better the present invention program, below in conjunction with drawings and embodiments, the embodiment of the present invention is described in further detail.
Situation as shown in earlier figures 5, uplink member carrier 1 is symmetric relation with downlink member carrier 1, uplink member carrier 2 is symmetric relation with downlink member carrier 2, uplink member carrier 3 is not symmetrical with downlink member carrier, deserves to be called capable member carrier 3 in the application and is asymmetrical uplink member carrier.Need to prove, although only show the situation of a uplink member carrier in Fig. 5, but, those skilled in the art will know that, technical scheme in the application can be applicable to the situation of a plurality of asymmetrical uplink member carrier widely, such as also comprise the situation of uplink member carrier 4 grades on the basis of Fig. 5.
At first, in the application, the binding relationship between can pre-defined up/down row member carrier.Concrete, can define binding relationship by cell configuration between up/down row member carrier, as specify the signaling of asymmetrical uplink member carrier to indicate the PDCCH by which downlink member carrier to carry.Up/down row member carrier for symmetry can keep its original symmetric relation, namely keeps the signaling indication of uplink member carrier to carry by the PDCCH on its symmetrical downlink member carrier.
In Fig. 5, up/down row member carrier 1 and 2 has relation one to one, can be carried by the PDCCH on downlink member carrier 1 the signaling indication of uplink member carrier 1, is carried the signaling indication of uplink member carrier 2 by the PDCCH on downlink member carrier 2.And for asymmetrical uplink member carrier 3, can bind by the pre-configured schedule information of uplink member carrier 3 and the PDCCH of downlink member carrier 1 or downlink member carrier 2 of specifying of residential quarter, for simplified characterization, below bind example with the PDCCH of the schedule information of specifying uplink member carrier 3 and downlink member carrier 2 and be illustrated, apparently, be equally applicable to specify the schedule information of uplink member carrier 3 and the PDCCH binding of downlink member carrier 2.
Relation between described predefined up/down row member carrier can be notified to user terminal (User Equipment, UE) by high-level signaling or broadcast control message.
Signaling indication method embodiment in the application in a carrier aggregation system can as shown in Figure 6, comprise:
S610: adopt the uplink member carrier in uplink member carrier of binding corresponding to bit mapping notice signaling indication.
As adopt the method for bit mapping (bitmap), indicate the dispatch of PUSCH on the one or more uplink member carrier in the uplink member carrier of the corresponding binding of described signaling.
More specifically, as shown in Figure 5, on downlink member carrier 2 in the uplink member carrier 2 and uplink member carrier 3 of indicating predetermined justice binding, indication be the dispatch of any or two in uplink member carrier 2 and uplink member carrier 3.For example adopt 2 bits to indicate in bitmap, the two states of each bit represents the scheduling indication of a uplink member carrier, as the scheduling to PUSCH on this uplink member carrier, and 1 expression scheduling, not scheduling of 0 expression, can be as shown in the table:
The signaling indexical relation of table 1.bitmap sign
S620: each uplink member carrier in the uplink member carrier of binding is carried out independent resource indication or the carrier wave that whole uplink member carrier of binding are formed by connecting is carried out the federated resource indication.
Illustrate, for example need at present by the PUSCH on indication uplink member carrier 2 and 3 on downlink member carrier PDCCH2, so, a kind of mode is that each uplink member carrier is carried out respectively the resource indication, the resource indicating mode that adopts in concrete mode and present LTE is identical, another kind of mode is to couple together situation as a resource for uplink member carrier 2 and 3 that will binding, due to the resource that connects as a complete resource pool, the carrier wave that therefore, can be formed by connecting to whole uplink member carrier of binding carries out the federated resource indication.
To rear a kind of mode, namely to the mode of joint instructions, can adopt the mode of Class1 or type 2, below make respectively introduction:
The mode of Class1 specifically can be passed through with the granularity of P Resource Block (Resource Block, RB) as scheduling of resource, if there is N in system so
RBIndividual resource, the resource with system is divided into
Individual resource group, the resource group that indication takies, its bit number is
For example can indicate the resource group that takies by the mode of Bitmap.The size of P is relevant with the bandwidth of system.Need to adjust according to the bandwidth of carrier aggregation the size of P in the LTE-A system, specifically can be as shown in Figure 7.In Fig. 7, that each bit is indicated is a RBG, and each RBG is comprised of P RB.The little rectangular box of each in figure is RB.
The mode of type 2 can be specifically with the granularity of P Resource Block as scheduling of resource, if there is N in system
RBIndividual resource is divided into the resource of system
Individual resource group is the P subset with whole set of resources, uses
Individual bit represents the numbering of the subset of resource group, adopt 1 bit to represent the original position (be used to indicate from the numbering of the RB of minimum, or from the numbering of the RB of maximum) of resource, indicate the resource of subset in each resource group, for example indicate with the mode of Bitmap, its bit number is
Its principle can be as shown in Figure 8.In Fig. 8, different fillings represents is the subset of different resource, always has 3 subsets, needs
The indication of individual bit adopts the mode of bitmap to indicate for all RB of a set in all P, and what other 1 bit represented is the mapping that the left side begins or begin to carry out from the right bitmap, and that each bit indication is a RB here.
In Fig. 7 and Fig. 8, the position that empty positional representation resource indication type 2 indicating modes can not be indicated, but can be by the indication of change original position.Resource indication Class1 is identical with the bit number that resource indication type 2 takies.The size of P is relevant with the bandwidth of system, can adjust according to the bandwidth of carrier aggregation the size of P in the LTE-A system.
S630: the uplink member carrier to binding adopts identical transmission block attribute to indicate or the uplink member carrier employing differential mode of binding is indicated the transmission block attribute of each uplink member carrier.
Described transmission block attribute comprises that Modulation and Coding Scheme, new data arrive the information such as indication, redundancy versions.
In a kind of situation, can adopt identical transmission block attribute to indicate to the uplink member carrier of binding.Similar in this mode and prior art.
In another situation, can adopt differential mode to indicate the transmission block attribute of each uplink member carrier to the uplink member carrier of binding.
For example, if the PUSCH of two uplink member carrier adopts different transmission block attributes to transmit, calculate according to the definition in transmission block attribute difference information field.Concrete, modulating-coding grade (the Modulation Coding Scheme of the PUSCH transmission block attribute indication of uplink member carrier 2, MCS) be made as x, the difference information territory of transmission block attribute is designated as and is made as delta, and the MCS of the PUSCH of uplink member carrier 2 is x+delta.
The grade of the MCS that for example defines in present LTE is 0～31, can indicate by the information of 5 bits the grade of current MCS so, differential bit can be 4 or 3 bits, what for example MCS was designated as 16 expressions is to adopt MCS grade 16 to carry out the transmission of PUSCH, differential bit is designated as-4, represents 16-4=12.Another one PUSCH adopts MCS grade 12 to carry out the transmission of PUSCH.
| Differential bit | Implication |
| 00 | -2delta |
| 01 | -delta |
| 10 | delta |
| 11 | 2delta |
Table 2. differential representation mode
What wherein delta represented is the quantization step of MCS difference, is 2 etc. such as being designated as delta.
Here need a bit, can adopt the mode of similar definition quantization step further to reduce the bit number of difference.
Still the situation in Fig. 5 is as example, and the principle of above-mentioned S620 to S630 can be as shown in Figure 9.In Fig. 9, resource indication and transmission block attribute are carried on the PDCCH3 of downlink member carrier 2.PDCCH3 represents the form incompatible with having LTE now, thus the PUSCH on indication uplink member carrier 2 and uplink member carrier 3.
Need to prove, above-mentioned S610, S620, S630 do not have dividing of sequencing.
S640: described bit mapping, resource indication and transmission block attribute are carried on predefined downlink member carrier transmit.
By such scheme, can realize that uplink member carrier, the resource of binding are indicated and the indication of transmission block attribute, thereby realize that the uplink member carrier number is greater than in the situation of downlink member carrier number, uplink member carrier being carried out the signaling indication.
The signaling indication method embodiment that below introduces in another carrier aggregation system of the present invention can as shown in figure 10, comprise:
S1010: adopt PDCCH resource independently to carry respectively resource indication and the transmission block attribute of the different uplink member carrier that the predefine downlink member carrier binds; Different PDCCH comprises the information of indicating different uplink carrier resources.
Figure 11 shows the schematic diagram of this mode.
Illustrate, for example the transmission of the PUSCH between each uplink member carrier and dispatch are independently, that is to say, the PUSCH of each uplink member carrier adopts independently that the transmission block attribute transmits, thereby also just need independently signaling indication.For this situation, can adopt two PDCCH resources to transmit respectively signaling indication for the PUSCH of dispatching uplink member carrier 2 and uplink member carrier 3 in downlink member carrier 2.
As shown in Figure 11, PDCCH2 can only be used for the indication of the dispatch of bound uplink member carrier, and comparing with PDCCH1 needs to increase the new information field that is used to indicate uplink member carrier.
Described different PDCCH comprises the information of indicating different uplink carrier resources, can comprise dual mode:
A kind of is directly to adopt the carrier wave ID of physics to indicate, and namely the number according to all uplink member carrier in current all residential quarters is numbered, and by the uplink member carrier that the numbering indication of physics is bound, other content remains unchanged.With respect to mode of the prior art, increase the physics numbering of indication carrier wave in the content at PDCCH2 on the basis of PDCCH1.
Another kind is the binding relationship according to predefined up/down row carrier wave, and the up-link carrier of binding is distinguished.For example in Figure 11, uplink member carrier 2 and 3 have been bound on downlink member carrier 2, uplink member carrier 3 so only need to be distinguished uplink member carrier 2 and 3 as attached binding carrier wave, does not need to distinguish by the physical carrier numbering of all member carriers.As with 0 uplink member carrier 2 that represents with downlink member carrier 2 symmetries, and represent and the asymmetrical uplink member carrier 3 of downlink member carrier 2 with 1.
S1020: the described PDCCH of transmission on the downlink member carrier of described uplink member carrier binding.
By such scheme, can realize that uplink member carrier, the resource of binding are indicated and the indication of transmission block attribute, thereby realize that the uplink member carrier number is greater than in the situation of downlink member carrier number, uplink member carrier being carried out the signaling indication.
Below introduce the embodiment of the method that the present invention detects indication signaling, Figure 12 shows the flow process of this embodiment, as scheming:
S1210: detect bit mapping on predefined downlink member carrier.
As previously mentioned, predefined uplink member carrier and downlink member carrier have binding relationship, can obtain by cell configuration.

For example adopt 2 bits to indicate in bitmap, the two states of each bit represents the scheduling indication of a uplink member carrier, as the scheduling to PUSCH on this uplink member carrier, and 1 expression scheduling, not scheduling of 0 expression, still can be as shown in table 1:
The signaling indexical relation of table 1.bitmap sign
Like this, terminal can learn that signaling on downlink member carrier is used to indicate one or more in the uplink member carrier of predefine binding.
S1220: detect resource indication and transmission block attribute on the downlink member carrier of bit mapping.

The mode of joint instructions, the mode as aforementioned described Class1 or type 2 that can correspondingly adopt detects.This dual mode, as previously mentioned:
The mode of Class1 specifically can be passed through with the granularity of P Resource Block (Resource Block, RB) as scheduling of resource, if there is N in system so
RBIndividual resource, the resource with system is divided into
Individual resource group, the resource group that indication takies, its bit number is
For example can indicate the resource group that takies by the mode of Bitmap.The size of P is relevant with the bandwidth of system.Need to adjust according to the bandwidth of carrier aggregation the size of P in the LTE-A system.
The mode of type 2 can be specifically with the granularity of P Resource Block as scheduling of resource, if there is N in system
RBIndividual resource is divided into the resource of system
Individual resource group is the P subset with whole set of resources, uses
Individual bit represents the numbering of the subset of resource group, adopt 1 bit to represent the original position (be used to indicate from the numbering of the RB of minimum, or from the numbering of the RB of maximum) of resource, indicate the resource of subset in each resource group, for example indicate with the mode of Bitmap, its bit number is
Described transmission block attribute can be the identical transmission block attribute indication to the uplink member carrier employing of binding, or the uplink member carrier of binding is adopted the transmission block attribute of each uplink member carrier of differential mode indication.Like this, detected transmission piece attribute on the resource of bit mapping on downlink member carrier, corresponding with the signaling indication on downlink member carrier, the uplink member carrier that binding can be detected adopts identical transmission block attribute, perhaps detects the transmission block attribute of each uplink member carrier in the uplink member carrier that obtains binding by differential mode.
The MCS that the PUSCH transmission block attribute indication of uplink member carrier 2 for example detected is made as x, and the difference information territory of transmission block attribute is designated as and is made as delta, can learn, on uplink member carrier 2, the MCS of PUSCH is x+delta.Specifically can be described in aforementioned indicating means.
