Method, system and device.
Background technology
In TD-LTE and other business or the scene of wireless communication system dynamic shared frequencies, TD-LTE is utilized and is perceived nothing
Line power technology uses other business or the idle frequence of wireless communication system.For multicarrier TD-LTE, can use distribute to
Frequency special TD-LTE as main carrier, using perceive the idle frequence of other obtained business or wireless communication system as
Secondary carrier.When the system of main business or higher preferential pole business resumes the frequency of secondary carrier, TD-LTE needs to stop in time
The only transmitting in secondary carrier, the terminal in secondary carrier is switched on main carrier.
, can be to major-minor carriers carry in order to reduce influence of the frequency dynamic change to TD-LTE communications in TD-LTE
Information configured.Specifically, there is data field and control domain on main carrier, carrying cell broadcast information, synchronizing information,
The control information such as common control information and up-downgoing schedule information, and the data of carrying terminal.Wherein, cell broadcast information can

Step 106, TD-LTE network sides are notified schedule information to terminal by main carrier；
In this step, can be to pass through the PDCCH on main carrier by main carrier；
In this step, schedule information is actually to distribute to the secondary carrier RB information of terminal, that is, is referred to for terminal
The secondary carrier RB information for distributing to terminal is shown.
Fig. 2 is that schedule information is notified schematic diagram to terminal by the PDCCH provided by the invention by cell main carrier,
As illustrated, frequency of the TD-LTE network sides on the main carrier of cell carries PDCCH, the PDCCH includes control domain, is used for
The different RB of the secondary carrier frequency of cell are distributed to different terminals by instruction, and by the narrow band frequency in secondary carrier retain regardless of
Match somebody with somebody.
In step 103 in Fig. 1, the secondary carrier configuration information carries to be sent in RRC resets message, uses non-TD-
LTE standard bandwidth, so the secondary carrier center frequency point and bandwidth will be extended, describes in detailed below as secondary carrier.
In the prior art, secondary carrier center frequency point f0Can be by absolute wireless frame number-evolution global telecommunications access system
System value（EARFCN-ValueEUTRA）The frequency sequence number of instruction converts to obtain, and agreement supports 0~65535 frequency, has used
46589 frequencies.After adding secondary carrier in cell, ARFCN-ValueEUTRA span may be not enough.This hair
It is bright in order to cell carrier accommodate more multiband, ARFCN-ValueEUTRA is extended.The present invention is in secondary carrier configuration information
The relevant information element of middle instruction secondary carrier frequency（IE）In, add a field evolution global telecommunications access system expanding value
（EARFCN-Extend）, for indicating frequency of the secondary carrier center frequency point for expanding location, and secondary carrier center frequency point is using public
Formula（1）It is calculated：
Formula（1）
Wherein, fLFor the lower end frequency of the secondary carrier band bandwidth, NoffsFor the frequency point number corresponding to the lower end frequency,
VEARFCN-ExtendFor field EARFCN-Extend values.
In the prior art, a width of TD-LTE standard bandwidths of band in secondary carrier configuration information, only 1.4,3,5,10,15
Or six kinds of bandwidth of 20MHz, it is contemplated that TD-LTE network sides of the invention and terminal support secondary carrier frequency polymerization, you can to support
Higher than the bandwidth of TD-LTE standard bandwidths, each nonstandard bandwidth less than maximum TD-LTE standard bandwidths can be supported again.Therefore,
The present invention uses downlink bandwidth（dl-Bandwidth-r10）And upstream bandwidth（ul-Bandwidth-r10）Field is arranged to have
The secondary carrier RB total values of body, in this case, in order to reduce the byte number of field occupancy, carrying secondary carrier can be set
Value after RB total values divided by certain integer.In order to increase bandwidth in distinguishing TD-LTE standard bandwidths, it is necessary to indicate the IE of bandwidth
Expanding value（Bandwidth-Extend）, length is 1 byte, for indicating d1-Bandwidth-r10 and u1-Bandwidth-
R10 fields are the RB total values of standard bandwidth or the secondary carrier using nonstandard bandwidth.
In Fig. 1 step 106, the secondary carrier RB for distributing to terminal is indicated to terminal, concrete mode is as follows.
In the prior art, it is specified that three kinds of RB distribution and instruction RB information modes, the present invention are directed to these three distribution sides
Formula provides modification, to support instruction to be more than RB information all on TD-LTE maximum standard bandwidths, and avoids in secondary carrier
Narrow-band interference signal take frequency.
1）RB uses resource allocation type 0（Type0）Carry out resource allocation
Secondary carrier frequency distribution type 0, using bit map（bitmap）The secondary carrier RB information of terminal is distributed in instruction,
Secondary carrier RB information is RB groups（RBG, RB group）, existing regulation bit map is 25 bytes, you can to indicate 25 groups
RBG, RBG size are according to total RB numbers of secondary carrier bandwidthIt is set to 1,2,3,4, as shown in Table 1.
Table one
The present invention is arrived using the indicating range of total RB numbers of two ways extension secondary carrier bandwidth first, increasing RBG sizes
5th, 6, second, the length of increase bit map.For example, during a width of 30MHz of secondary carrier band, expand RBG sizes, RBG can be used for 6,
Bit map length is 25bit, and this method is not required to the byte number of increase instruction RB information, or can use RBG as 4, bit map
Length is at least 38 bytes, this method increase the byte number of instruction RB information.
That is, in this fashion, when indicating secondary carrier RB information for terminal, using bit map and RBG
The mode of group is implemented, wherein, extended bit mapping byte number or the instruction of RBG groups number.
Narrow-band interference signal is avoided under the Type0 modes of the present invention, i.e. TD-LTE network sides do not give terminal distribution arrowband
RBG where interference signal and its both sides protection band.
2）RB carries out resource allocation using resource allocation type Type1
In this mode, for the RBG of terminal distribution it is in the prior art some RBG in a RBG subset.First will
RBG is assigned as N number of RBG subsets, then uses bit map to indicate some RBG in some RBG subset again, as RB information.
Using method provided by the invention, RBG subsets are divided still according to prior art, to support the instruction model of secondary carrier bandwidth
Enclose, then to increase the length of bit map, indicate some RBG in some RBG subset.
In this mode, in order to avoid narrow-band interference signal, TD-LTE network sides do not give terminal distribution narrow-band interference signal
And its RBG where the protection band of both sides.
3）RB carries out resource allocation using resource allocation type Type2
In this mode, still according to prior art, it is designated as the continuous RBG of terminal distribution starting position（start）
With RBG numbers（length）.But in the present invention, in order to extend the indicating range of secondary carrier bandwidth, add continuous RBG's
Starting position and the span of RBG numbers.
In this mode, in order to avoid narrow-band interference signal, TD-LTE network sides do not give terminal distribution narrow-band interference signal
And its RBG where the protection band of both sides, i.e., the secondary carrier that terminal distribution is located at narrow-band interference signal side is only in distribution
Bandwidth.
