Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention is explicitly described, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, shall fall within the protection scope of the present invention.

Hereinafter, the part term in the application is explained, in order to those skilled in the art understand that.

1), RAN equipment is a kind of equipment that terminal is linked into wireless network, including but not limited to: evolved node B (evolved Node B, eNB), radio network controller (radio network controller, RNC), node B (Node B, NB), base station controller (Base Station Controller, BSC), base transceiver station (Base Transceiver Station, BTS), Home eNodeB (such as, Home evolved NodeB, or Home Node B, HNB), Base Band Unit (BaseBand Unit, BBU), Wifi Access point (Access Point, AP) etc..

2), terminal, also referred to as user equipment (User Equipment, UE), it is a kind of equipment for providing a user voice and/or data connectivity, for example, handheld device, mobile unit, other processing equipments for being connected to radio modem etc. with wireless connecting function.

3), " multiple " refer to two or more."and/or" describes the incidence relation of affiliated partner, indicates may exist three kinds of relationships, for example, A and/or B, can indicate: individualism A exists simultaneously A and B, these three situations of individualism B.Character "/" typicallys represent the relationship that forward-backward correlation object is a kind of "or".

Currently, the diversification of the CA bandwidth combination ability due to terminal, the bandwidth resources that usually will appear operator combine the case where cannot be considered in terms of the terminal of various bandwidth combination abilities.Such as: the band bandwidth combination of resources of operator is the 15M bandwidth of the 20M bandwidth+Band20 of Band3, for the 15M bandwidth of the 20M bandwidth+Band20 of Band3, the protocol definition CA bandwidth combination ability of two kinds of terminals, respectively set0 and set1, wherein, set0 maximum supports the 10M bandwidth of the 20M bandwidth+Band20 of Band3, set1 maximum to support the 15M bandwidth of the 20M bandwidth+Band20 of Band3.At this point, RAN equipment can configure 20M according to Band3, Band20 configures 15M to carry out CA configuration, at this point, the terminal of set1 can be CA, and the terminal of set0 can only do single carrier business.Alternatively, RAN equipment configures 20M, Band20 according to Band3 10M is configured to carry out CA configuration, the terminal of two kinds of abilities of set0, set1 is only the CA of 20M+10M at this time, to the performance of the terminal of a variety of CA bandwidth combination abilities can not be allowed to be optimal in the same band bandwidth combination of resources.The application proposes a kind of carrier polymerizing method aiming at the problem that performance of terminal of various CA bandwidth combination abilities can not be allowed in a band bandwidth combination of resources to be optimal in prior art simultaneously.RAN equipment is practical in the method uses the combination of the first bandwidth (can also be referred to as actual bandwidth combination), the terminal to match is combined with the actual bandwidth for CA bandwidth combination ability, RAN equipment configures actual bandwidth combination for it；Unmatched terminal is combined with the actual bandwidth for CA bandwidth combination ability, RAN equipment configures second of bandwidth combination for it, the CA bandwidth ability combination that unmatched terminal is combined in second of bandwidth combination with CA bandwidth combination ability with the actual bandwidth matches, the actual bandwidth used with RAN equipment combines difference, therefore can be referred to as virtual bandwidth combination.So, CA bandwidth combination ability can be allowed to combine the terminal to match with actual bandwidth, CA is realized using actual bandwidth combination, unmatched terminal is combined in the combination of CA bandwidth ability, which with actual bandwidth, can realize CA using the second bandwidth to match combination is combined with itself CA bandwidth ability, to realize that the terminal of different CA bandwidth combination abilities can configure CA, so that bandwidth resources are more fully utilized, the downlink throughput capacity of terminal is promoted, and property can be promoted.

For example, referring to FIG. 1, it is a kind of schematic diagram of carrier polymerizing method provided in an embodiment of the present invention.As shown in Figure 1, the actual bandwidth group that RAN equipment uses is combined into the 15M of the 20M+Band 20 of Band3.For the terminal of set1, CA bandwidth combination ability is combined with the actual bandwidth to match, therefore configures actual bandwidth combination for the terminal；For the terminal of set0, although its CA bandwidth combination ability combines mismatch with the actual bandwidth, RAN equipment is configured with the virtual bandwidth to match with the terminal of the set0 for it and combines, i.e. the 10M of the 20M+Band 20 of Band3.In this way, CA configuration may be implemented in two kinds of terminal.

Referring to FIG. 2, Fig. 2 is a kind of flow diagram for carrier polymerizing method that the embodiment of the present invention proposes.As shown in Fig. 2, the executing subject of the embodiment of the present invention can be RAN equipment, the method in the embodiment of the present invention includes:

S201, RAN equipment determine first band wide array according to the bandwidth of main carrier and the bandwidth of secondary carrier；

S202 obtains the CA ability of the first terminal and second terminal that access the RAN equipment；

S203 determines the CA ability and the first band of first terminal according to the CA ability of first terminal Wide array mismatches, and according to the CA ability of second terminal, determines that the CA ability of second terminal is matched with the first band wide array；

S204 configures the combination of the second bandwidth for first terminal, configures the first band wide array for second terminal, wherein the second bandwidth combination is matched with the CA ability of the first terminal.

It should be noted that the above first band wide array and the combination of the second bandwidth include that main carrier bandwidth and secondary carrier bandwidth, wherein first band wide array and the main carrier bandwidth of the second bandwidth combination are identical, and secondary carrier bandwidth is different.For example, main carrier bandwidth is the 20M of Band 3, secondary carrier bandwidth is respectively the 15M and 10M of Band 20.

It can be seen that, above embodiments combine unmatched terminal with actual bandwidth for the combination of CA bandwidth ability, and RAN equipment is configured with virtual bandwidth (for example, 10M of Band 20) for it, to guarantee that it can also configure CA, so that bandwidth resources are adequately utilized.After having configured virtual bandwidth, RAN equipment can also further be the terminal distribution resource.That is, referring to FIG. 3, the flow diagram of its another carrier polymerizing method proposed for the embodiment of the present invention.It is further comprising the steps of in addition to step shown in Fig. 2:

S205, RAN equipment are combined according to the second bandwidth, distribute channel resource to first terminal；

S206, RAN equipment distribute channel resource according to first band wide array, to second terminal.

The above channel resource is PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) resource.At this point, carrying out downlink space interface resource, the i.e. distribution of PDSCH resource in the way of various bandwidth according to the type of the terminal of actual schedule in the cell for being configured for virtual bandwidth.Referring to FIG. 4, it is a kind of schematic diagram of PDSCH resource distribution mode provided in an embodiment of the present invention.As shown in figure 4, being configured for after the CA of set0 terminal for the 15M cell of Band20, the resource allocation of PDSCH is carried out to the terminal of respective bandwidth according to two kinds of bandwidth of 15M and 10M respectively.For example, second terminal matched for CA ability can distribute PDSCH resource according to 15M mode in entire frequency range, first terminal unmatched for CA ability can be according to 10M mode in center 10M frequency allocation PDSCH resource.It should be noted that center 10M frequency range here is only for example, any portion of 10M frequency range can be taken to carry out PDSCH resource allocation.

The above channel resource can also be PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) resource.Since PDCCH physical resource is full bandwidth Discrete Mapping, the logic CCE (Control Channel Element, control channel element) of different bandwidth can very likely map Onto partly overlapping physics REG (Resource Element Group, resource unit group) position, demodulates and fail so as to cause terminal.A kind of mode can avoid the position REG from being overlapped by accurately calculating；Another way carries out PDCCH resource distribution according to various bandwidth not in same cell, at this time, for being configured for the cell of virtual bandwidth, its PDCCH channel is all reserved to the terminal of configuration true bandwidth and cell common signaling uses, and the SCC terminal for being configured with virtual bandwidth can be handled according to following two mode:

First: cross-carrier scheduling scheme, as shown in Figure 5, pass through the control channel resource of main carrier (such as PDCCH resource, can certainly be EPDCCH resource) carry the PDCCH of secondary carrier, such as, the SCC (virtual 10M bandwidth) configured in set0 is cross-carrier scheduling, and the PDCCH channel of SCC is indicated by the PCC of Band3.At this point, the PDCCH information of the secondary carrier of first terminal is sent by the control channel resource of main carrier, the PDCCH information of the secondary carrier of second terminal is sent by the control channel resource of secondary carrier.That is the control channel resource of secondary carrier distributes to second terminal, and the control channel resource allocation of the secondary carrier of first terminal is in the control channel of main carrier.

Second: EPDCCH scheme, as shown in fig. 6, carrying the PDCCH of secondary carrier using EPDCCH.For example, SCC (virtual 10M bandwidth) the control information of the terminal of configuration set0 is indicated by EPDCCH channel.At this point, the PDCCH information of the secondary carrier of first terminal is sent by the EPDCCH resource of secondary carrier, the PDCCH information of the secondary carrier of second terminal is sent by the PDCCH resource of secondary carrier.That is the PDCCH resource of secondary carrier distributes to second terminal, and the EPDCCH resource of secondary carrier distributes to first terminal.EPDCCH specifies a part of resource block (RB) to be used as control channel on PDSCH channel.

In the embodiment above, RAN equipment is the RAN equipment where main plot or main carrier, and the RAN equipment can realize that the bandwidth to main carrier is that itself knows to the acquisition of terminal CA ability by the capability reporting of terminal, can be obtained by inquiry to the bandwidth of secondary carrier.Usual each cell can safeguard the information list of a adjacent area, terminal is given the correct time on A4, the subdistrict frequency point measured and PCI (Physical Cell Identifier can be taken, Physical Cell Identifier), then PCC can inquire the actual bandwidth of the cell (i.e. secondary cell) by this information in neighboring BS information table.It is described in detail with reference to the accompanying drawing.

With continued reference to FIG. 7, it is the signaling flow graph of another carrier polymerizing method provided in an embodiment of the present invention.As shown in fig. 7, this method comprises the following steps:

S702, main plot is to terminal transmission bandwidth capability query message.

S703, terminal receive the bandwidth ability query messages that main plot is sent, and according to bandwidth ability query messages, the actual bandwidth combination ability of terminal is returned to main plot.

S704, main plot is to secondary cell transmission bandwidth query messages.

S705, secondary cell receive the bandwidth resources query messages that main plot is sent, and return to query result to main plot, wherein query result includes the networking bandwidth of secondary cell.

S706, main plot receives query result, determine whether actual bearer bandwidth of the terminal in secondary cell matches with the networking bandwidth of secondary cell, if it is determined that the networking bandwidth of actual bearer bandwidth and secondary cell of the terminal in secondary cell mismatches, then message is set to the RRC connection reconfiguration that terminal transmission carries virtual bandwidth information.

S707, the RRC connection reconfiguration that terminal reception carries virtual bandwidth information sets message, and the virtual bandwidth of the secondary carrier according to virtual bandwidth information configuration in the carrier wave polymerization in secondary cell, and returns to configuration result.

Such as: the actual bandwidth combination ability of terminal is Band3 20M+Band20 10M, and the networking bandwidth of the Bnad20 of secondary cell is 15M, it can then determine that terminal bandwidth ability in secondary cell Band20 is limited, therefore virtual bandwidth of the configurating terminal in secondary cell is 10M, to realize that RAN equipment can distribute channel resource to the user terminal according to the virtual bandwidth of 10M in secondary cell Band20, channel resource is distributed to the user terminal according to the true bandwidth of 20M in the Band3 of main plot.
