Abstract
Embodiments of the invention provide an LTE frequency band processing method and an LTE frequency band processing device. The LTE frequency band processing method comprises the following steps: selecting a first frequency band number, wherein the first frequency band number is any undefined frequency band in the 3GPP36.101 standard; defining a sub frequency band under the first frequency band number; selecting continuous frequency point numbers within the downlink frequency point number range in the 3GPP36.101 standard as an uplink frequency point number range corresponding to the sub frequency band; and selecting continuous frequency point numbers within the uplink frequency point number range in the 3GPP36.101 standard as a downlink frequency point number range corresponding to the sub frequency band.

Especially, to FDD frequency sub-band, in the freqinfo of SIB2, indicate up frequency point number and upstream bandwidth, TDD frequency sub-band does not carry this field.
IRAT-ParametersUTRA-TDD768 cell in UE capability reporting message is used to refer to the ability that UE supports 7.68Mchip/sTDD spread spectrum system originally, because this type systematic is abandoned at present, does not have the network in actual use.Therefore this cell is meaningless, example of the present invention has redefined this cell, some positions before in this cell are used to indicate the UE ability that dedicated communications network increases, wherein whether support frequency sub-band for UE for one, if support frequency sub-band, then this cell can carry the frequency sub-band number of the frequency sub-band quantity of UE support and the frequency sub-band of each support.
