Table two
Wherein, existing frequency range and extended frequency band are indicated respectively, terminal is to the support of existing frequency range, comprise the situation that to support a, b, three frequency ranges of c at most and can support a, b, c, four frequency ranges of d at most, consider compatibility, the indicating mode of existing frequency range is identical with the mode of existing protocol defined, and the institute that is the existing frequency range of terminal support might mode be provided with the directive of correspondence one by one, and directive is corresponding to a kind of frequency range support situation of terminal.For making terminal more fully support various frequency ranges, also enabled the directive of " Notabcd " in the agreement, their expression terminals are not supported existing frequency range, and only support extended frequency band.If terminal is not supported existing frequency range, value in " type and parameter " among " the Radio frequency bands " in the table two item is " Notabcd " so, at this moment, " Radio Frequency bands ext " item is certain existence, promptly necessarily has extended frequency band.The directive of " Notabcd " exists in former agreement, because therefore original terminal federation band support there is no practical significance, the present invention does not support existing frequency range to use as terminal the directive of " Notabcd ".In the table two, the number of " Radio frequency bands extension list " expression extended frequency band, after being reported to system side, the number of the extended frequency band that system can support according to this definite terminal, this be optional (OP) item.
Among the present invention, described terminal is for supporting the terminal of UTRA tdd mode, as TD-SCDMA terminal, LTE terminal etc., described terminal is supported each spreading rate under the TDD, promptly supports present 1.28Mcps, 3.84 Mcps and three kinds of spreading rates of 7.68 Mcps at least.
With extended frequency band e, f, g, h, i, j, k, l, m, n, these 12 of o, p being arranged is example, for each extended frequency band is provided with a directive.When certain TDD terminal was supported extended frequency band, the directive of the extended frequency band correspondence that this TDD terminal is supported was selected in the directive set of extended frequency band and gets final product.Support two extended frequency bands of e, k as certain terminal, then the set of the directive of extended frequency band is { directive of e, the directive of k } in this TDD terminal.
Provide some examples below with the convenient understanding that these parameters are used.
If TD-SCDMA terminal band support a, b, the frequency bands supported ability of reporting terminal the time, utilize " Radio frequency bands IE " to report, in " Radio frequency bands ", select the directive of a+b correspondence for use." Radio frequency bands extension list " tabulation does not exist.
Similarly, if LTE terminal band support a, b, the frequency bands supported ability of reporting terminal the time, utilize " SupportedUTRA-TDD 128Band " to report, in " supportedUTRA-TDD 128band ", select the directive of a+b correspondence for use." SupportedUTRA-TDD128BandExtList " do not exist.
If a TD-SCDMA terminal band support e, the frequency bands supported ability of reporting terminal the time, utilize " Radio frequency bands IE " to report, in " Radio frequency bands ", select the directive of Notabcd correspondence for use." the Radio frequency bands extension list " existence of tabulating, the directive set of extended frequency band is { directive of e }.
Similarly, if a LTE terminal band support e, the frequency bands supported ability of reporting terminal the time, utilize " Radio frequency bands IE " to report, " SupportedUTRA-TDD128Band " selects the directive of Notabcd correspondence for use." SupportedUTRA-TDD128BandExtList " exists, and the directive set of extended frequency band is { directive of e }.
If TD-SCDMA terminal band support a, e, the frequency bands supported ability of reporting terminal the time, utilize " Radio frequency bands IE " to report, in " Radio frequency bands ", select the directive of a correspondence for use.The Radio frequency bands extension list existence of tabulating, " the Radio frequencybands extension list " existence of tabulating, the directive set of extended frequency band is { directive of e }.
Similarly, if LTE terminal band support a, e, the frequency bands supported ability of reporting terminal the time, utilize " Radio frequency bands IE " to report, " SupportedUTRA-TDD128Band " selects the directive of a correspondence for use." SupportedUTRA-TDD128BandExtList " exists, and the directive set of extended frequency band is { directive of e }.
The indicating means of frequency bands supported by terminal of the present invention needn't improve the indicating mode of existing frequency range, with the directive set extended frequency band is indicated, and increases a new directive when increasing extended frequency band and gets final product the expansion of easier band support.
