Table 2

Based on the problems referred to above, the embodiment of the present invention proposes a kind of channel width allocation plan, specific as follows states:

Embodiment one

A kind of channel width configuration system that the embodiment of the present invention one proposes, as it is shown in figure 1, include at least one terminal and at least one base station, wherein:

Terminal, for sending frequency range tenability information to base station.

Wherein, frequency range tenability information indicate that terminal supports by base station to the ability of the channel width of any frequency range configuration in system.

Terminal sends frequency range tenability information to base station, it is possible to include following two ways:

First kind of way: terminal sends the channel indication message comprising frequency range tenability information to base station.

Frequency range tenability information can include the frequency range that terminal is supported, it is also possible to including on the frequency range basis that terminal is supported, increases the channel width that terminal is supported in the frequency range supported.When then terminal reports the frequency range tenability information of self to base station, it is possible to select the frequency range that reporting terminal is supported, it is also possible to select the frequency range that reporting terminal is supported and the channel width supported in this frequency range.Particularly as follows:

A: terminal sends the channel indication message comprising frequency range mark to base station, its Mid Frequency mark is the mark of the frequency range that terminal can be supported.

In this kind of mode, it is possible to acquiescence terminal supports all of channel width in the frequency range that this frequency range mark is corresponding.

For example, it is assumed that terminal sends the channel indication message comprising frequency range mark 8 to base station, then mark terminal can all of channel width in band support 8.

B: send to base station and comprise the channel indication message of corresponding relation between frequency range mark and channel width set.

In this kind of mode, terminal reports the frequency range self supported and concrete which channel width supported in this frequency range to base station.

(English: BandwidthSet) field increases the channel width set that terminal is supported in BandwidthSet field bin width can be reported to arrange by extension.As described in Table 3, in BandwidthSet field, increase by 15, and the frequency range sent is designated 8, then show that the frequency range tenability information of terminal be the channel width in band support 8 is the configuration of 15MHZ.In BandwidthSet field, increase by 15,20.And the frequency range sent is designated 9, then show that the frequency range tenability information of terminal be the channel width in band support 9 is 15MHZ and 20MHZ.

Table 3

The second way: terminal sends the carrier aggregation capacity reporting message comprising frequency range tenability information to base station.

In current standard, prescribed terminal carries out giving the correct time on carrier aggregation capacity, need to report frequency range combination parameter (English: BandCombinationParameters) parameter, BandCombinationParameters contains N number of frequency range parameter (English: BandParameters) (wherein, N carries out the Band quantity of carrier aggregation while being support), each BandParameters parameter contains Band numbering and carrier aggregation bandwidth class is (English: CA-BandwidthClass) ability instruction.The instruction of CA-BandwidthClass ability is specific as follows to be stated shown in table 4.

Table 4

Wherein, in above-mentioned table 4, A represents that single carrier wireless resource block is (English: ResourceBlock, abbreviation: RB) less than 100, B represents that dual carrier RB is not less than 25, and is not more than 100, C represent dual carrier and RB more than 100 less than 200, by that analogy.

The BandCombinationParameters parameter of terminal to report such as, comprises two groups of BandParameters parameters: first group of Band is numbered 1, CA-BandwidthClass is A, second group of Band is numbered 3, CA-BandwidthClass is A, then it represents that this terminal supports the carrier aggregation combination of a carrier wave in Band1 and an intercarrier in Band3.Terminal to report BandCombinationParameters parameter and for example only comprises one group of BandParameters parameter: it is C that this group Band is numbered 40, CA-BandwidthClass, then it represents that terminal supports continuous two carrier aggregation on Band40.

It addition, specify according to standard, terminal carries out carrier aggregation capacity and reports, and (English: SupportedBandwidthCombinationSet) ability, this ability represents the channel width combination that carrier aggregation is supported also to comprise support bandwidth composite set.

Such as described in Table 5, Band7 frequency range supports two kinds of SupportedBandwidthCombinationSet abilities, if terminal to report is 0, only supports the channel width combination of front two row, if terminal to report is 1, and the channel width combination of three row after supporting.

Table 5

Based on the above-mentioned elaboration to terminal to report carrier wave carrier aggregation capacity message, in the technical scheme that present example proposes, it is proposed to report mechanism based on current carrier aggregation, this signaling of multiplexing is used for terminal to report frequency range tenability.Particularly as follows:

A: by base station feedback one-segment single carrier ability, indicating the spread channel bandwidth ability that terminal is supported.

BandCombinationParaneters field write frequency range mark in carrier aggregation capacity reporting message, sends the carrier aggregation capacity reporting message of write frequency range mark to base station.

Its Mid Frequency mark is the mark of the frequency range that terminal can be supported.

Such as terminal can comprise single BandParameters in the BandCombinationParameters parameter reported, and BandParameters Mid Frequency is designated as Band8, CA-BandwidthClass ability and is designated as A.According to the signaling format of regulation in standard, this kind reports the mode of carrier aggregation capacity to be support, but as a rule, one-segment single carrier does not possess any polymerizing power, therefore this reporting for carrier aggregation is not possess meaning still, in the technical scheme that the embodiment of the present invention proposes, it is possible to represent that all channel widths configuration that this frequency range is designated in the Band8 of 8 by terminal is all supported by this signaling.

B: indicate the different spread channel bandwidth ability that terminal supports by feedback frequency range single carrier ability and SupportedBandwidthCombinationSet.

Frequency range tenability information also includes the channel width that terminal is supported in the frequency range supported；

SupportedBandwidthCombinationSet field in carrier aggregation capacity reporting message, the channel width mark of the channel width that write terminal is supported in the frequency range supported.Or

In SupportedBandwidthSet parameter in carrier aggregation capacity reporting message, the channel width mark of the channel width that write terminal is supported in the frequency range supported.

In above-mentioned A feedback system, only by carrier aggregation capacity reporting message signals base, the frequency range mark that terminal is supported, base station identifies according to the frequency range of terminal to report, acquiescence terminal is all of channel width configuration in the frequency range supporting this frequency range mark corresponding, and cannot the accurate characterization terminal support situation to one group of specific bandwidth ability.The technical scheme that the embodiment of the present invention proposes proposes to distinguish different channels bandwidth ability by multiplexing SupportedBandwidthCombinationSet signaling message.

Such as, defining SupportedBandwidthSet parameter in table 6 below, 0 represents Band8 supports all channel widths except 20MHz, and 1 represents all channel widths of support.Then, ceased by SupportedBandwidthCombinationSet signaling, characterize the terminal tenability to different channels bandwidth.

Table 6

Base station, for obtaining the frequency range tenability information of terminal, base station is according to the frequency range tenability information obtained, and the instruction terminal frequency range to supporting measures and/or indicates this terminal to access this frequency range.

Wherein, it is thus achieved that the frequency range tenability information of terminal, it is possible to include following two ways:

First kind of way: in the channel indication message that the terminal received sends, it is thus achieved that the frequency range tenability information of terminal.

Frequency range tenability information includes the frequency range that terminal is supported, it is also possible to including on the frequency range basis that terminal is supported, increase the channel width that terminal is supported in the frequency range supported.Then base station is in the channel indication message that the terminal that receives sends, it is thus achieved that during the frequency range tenability information of terminal, it is possible to obtain the frequency range that terminal is supported, it is also possible to obtain the frequency range that terminal is supported, and the channel width supported in this frequency range.Particularly as follows:

A: receive the channel indication message that terminal sends, it is determined that the frequency range mark in channel indication message, identifies according to described frequency range, it is determined that the frequency range that terminal is supported.

B: determine the channel width set in channel indication message, according to frequency range mark and channel width set, it is determined that the frequency range that terminal is supported, and the channel width that terminal described in the frequency range supported is supported.

BandwidthSet field can be reported by extension, BandwidthSet field increases the channel width set that terminal is supported.As shown in Table 3 above, in BandwidthSet field, increase by 15, and the frequency range sent is designated 8, then show that the frequency range tenability information of terminal be the channel width in band support 8 is 15MHZ.In BandwidthSet field, increase by 15,20.And the frequency range sent is designated 9, then show that the frequency range tenability information of terminal be the channel width in band support 9 is 15MHZ and 20MHZ.

The second way: in the carrier aggregation capacity reporting message received, it is thus achieved that the frequency range tenability information of terminal.

In the technical scheme that present example proposes, it is proposed to report mechanism based on current carrier aggregation, this signaling of multiplexing is used for terminal to report frequency range tenability.Particularly as follows:

A: frequency range tenability information includes the frequency range that terminal is supported, receive the carrier aggregation capacity reporting message that terminal sends, determine the frequency range mark in the frequency range combination parameter BandCombinationParaneters in carrier aggregation capacity reporting message, identify according to frequency range, it is determined that the frequency range that terminal is supported.

Wherein, the BandCombinationParaneters field in carrier aggregation capacity reporting message, it is determined that the frequency range instruction in BandParameters, identifies frequency range instruction as frequency range.

B: frequency range tenability information also includes the channel width that terminal is supported in the frequency range supported, the SupportedBandwidthCombinationSet field in carrier aggregation capacity reporting message, it is thus achieved that channel width identifies.Identify according to frequency range, it is determined that the frequency range that terminal is supported, and according to the channel width mark obtained, it is determined that the terminal channel width that terminal is supported in the frequency range supported.

Frequency range tenability information also includes the channel width that terminal is supported in the frequency range supported, determine the support bandwidth aggregation SupportedBandwidthSet parameter in carrier aggregation capacity reporting message, according to SupportedBandwidthSet parameter, acquisition channel width identifies, it is determined that the terminal channel width that terminal is supported in the frequency range supported.

Terminal, for receiving the instruction message that base station sends, the message frequency range to supporting measures and/or accesses this frequency range as indicated.

Configuring system based on the channel width shown in Fig. 1, the embodiment of the present invention one also proposes a kind of channel width collocation method, as in figure 2 it is shown, its concrete handling process is such as following:

Step 21, terminal sends frequency range tenability to base station.

Can report bin width that BandwidthSet field is set by extension, BandwidthSet field increases the channel width set that terminal is supported.For example, it is possible in BandwidthSet field, increase by 15, and the frequency range sent is designated 8, then show that the frequency range tenability information of terminal be the channel width in band support 8 is 15MHZ.In BandwidthSet field, increase by 15,20.And the frequency range sent is designated 9, then show that the frequency range tenability information of terminal be the channel width in band support 9 is 15MHZ and 20MHZ.

In current standard, prescribed terminal carries out giving the correct time on carrier aggregation capacity, need to report BandCombinationParameters parameter, BandCombinationParameters contains N number of BandParameters parameter (wherein, N carries out the Band quantity of carrier aggregation while being support), each BandParameters parameter contains Band numbering and the instruction of CA-BandwidthClass ability.

It addition, specify according to standard, terminal carries out carrier aggregation capacity and reports, and also comprises SupportedBandwidthCombinationSet ability, and this ability represents the channel width combination that carrier aggregation is supported.

Such as, Band7 frequency range supports two kinds of SupportedBandwidthCombinationSet abilities, if terminal to report is 0, only supports the channel width combination of front two row, if terminal to report is 1, and the channel width combination of three row after supporting.

Step 22, base station obtains the frequency range tenability information of terminal.
