Embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.The present invention provides a kind of corresponding RRM information of being obtained neighbor cell in evolvement network by terminal UE, and offers the scheme of this cell base station (eNodeB), solves the problem of obtaining RRM information between eNodeB.In order to realize the radio resource management function between the sub-district, the Radio Resource situation of neighbor cell need be understood in the base station.The inventive method process as shown in Figure 4, wherein, the basic acquisition process of RRM information is: adjacent base station (comprises the resource information of adjacent sub-district: the upstate of resource load information, information of radio resource allocation, Radio Resource) be included in the downlink frame; This resource information of terminal parses, and send to this cell base station together with self this measured cell downlink channel conditions and adjacent cell downlink channel conditions; This cell base station is engaged in corresponding RRM function according to the up channel situation of these information and self this cell load information that obtains, this local resource distribution condition and UE.
In evolvement network, the downlink transfer of eNodeB adopts the OFDM modulation, and the transmission of data is that unit carries out with the frame, and that its multi-access mode adopts is OFDMA/TDMA.In order to carry out the management of effective presence of intercell interference, strict synchronism in time between different districts in the evolvement network.The downlink OFDMA data frame format that carries cell load information that the present invention provides as shown in Figure 5.
Downlink data frame format of the present invention has three parts in the beginning of each frame: main lead code, auxilliary lead code, broadcast message.These three parts are described below respectively:
Main lead code: be the pseudo random sequence that is modulated on the subcarrier, be mainly used in the synchronous of sub-district.In order to guarantee that the sub-district is synchronous fast, identical sequence is all adopted in all sub-districts.Main lead code generally only takies 1 OFDM symbol.
Auxilliary lead code: be the pseudo random sequence that is modulated at one group of mutually orthogonal on the subcarrier, be mainly used in functions such as frame timing, distinguishing cell ID, initial channel estimation and measurement, the employed auxilliary preamble sequence of different districts is mutually orthogonal, thereby can allow terminal distinguish different sub-districts.The initial phase of the auxilliary lead code of each sub-district is relevant with the present load of this sub-district, and terminal is on by the synchronous basis of main lead code, and the initial phase of the auxilliary preamble sequence in each sub-district that can receive by detection obtains the load information of each sub-district.Length is the cell load information that 256 auxilliary preamble sequence can be represented 8 bit quantizations.Auxilliary lead code generally only takies 1 OFDM symbol.
Broadcast message: be used to provide the resource allocation mapping table of Cell Broadcast CB and every frame, solve one's own data so that terminal can be correct.For the reception to this Cell Broadcast CB of the terminal that guarantees cell edge, this part data will adopt the coding of higher gain, and the employing PN sequence scrambling relevant with specific cell.
The main purpose of above-mentioned data frame format is the load information that can obtain the sub-district when will allow terminal carry out cell measurement work, does not need to increase extra complexity.The auxilliary lead code that one group of mutually orthogonal pseudo random sequence that terminal utilization this locality has cured is gone and received carries out related calculation, the peak value of the relevant peaks that calculates by each sequence carries out corresponding channel measurement, obtains the load information of respective cell by the phase place of relevant peaks.
Terminal is after parsing the cell load information that sends the base station, in the measurement report that sends to the base station, enclose the indication whether load changes, this indication only takies 1 bit, this bit can be united transmission with CQI, after the physical layer of base station is received this information, this information is sent to the upper strata by the primitive between physical layer and the upper strata; The upper strata is according to the indication of a plurality of terminals of receiving, and decision is to the adjacent cell load information of which terminal request, and terminal sends to the base station with load information again after receiving the solicited message that send the base station.
In the said process, the indication of the load variations of 1 bit all exists in each measurement report that reports, and real adjacent cell load information then only just sends when the request of receiving the base station.
Concrete message flow as shown in Figure 6.In Fig. 6:
(1) the continuous transmission downlink frame in the base station of this sub-district and adjacent sub-district comprises the load information of this sub-district after the quantification in the downlink frame;
(2) load information of each sub-district of terminal parses, at first determine the downlink information of operable several sub-districts according to correlation peak, draw the quantification load information of these several sub-districts then according to the phase place of relevant peaks, and do down: if the preceding N/2 bit of the N bit quantization value of each sub-district that parses is all constant as judging, think that then load does not change, load variations is designated as 0, otherwise thinks that load changes, and load variations is designated as 1;
(3) base station to this sub-district of terminal periodic sends measurement report, comprises current load variations indication in the measurement report;
(4) this cell base station is received the measurement report that each terminal sends over, and analyzes load variations indication wherein, and sends adjacent cell load information request message according to analysis result to relevant terminal;
(5) after terminal is received the load information request message, in the measurement report that the next one reports, comprise adjacent cell load information.
(2) of said process are relevant with the quantizing process of cell load.The quantification of cell load is wished as far as possible accurately, restricts but also be subjected to two factors, that is:
The phase deviation resolution capability: because the signal of different base station exists path delay and multipath effect, be the sequence of 2N for length, its phase resolution is lower than 1/2N, so its actual useful quantitative figure place can be less than N;
The frequency of terminal to report cell load information: the figure place of quantification is high more, and it is just frequent more that the terminal to report load variations is designated as 1 situation, and the frequency of the flow process that load reports is also big more, so quantization digit can not be excessive.
For this reason, the present invention is chosen in and adopts length is under the situation of sequence of 2N, the value of phase quantization just is decided to be N, terminal is after detecting phase deviation, the preceding N/2 of quantized value is as the foundation that judges whether to take place load variations, and the back N/2 of quantized value participates in computing with lower weights just as with reference to value when carrying out respective handling after the base station receives.
In (4) of said process, the analytic process of load variations indication is as follows:
This cell base station is indicated the mapping relations that draw as shown in Figure 7 according to the load variations that receives.Wherein, the terminal 701 that the load variations indicated value that reports equals 1 is classified on the left side one as, sorts according to the number of the adjacent sub-district of its received signal; The right one is classified these as and is indicated pairing sub-district 702, the load variations indication of middle connecting line 703 expression terminal to report and the corresponding relation between the respective cell.This cell base station is at first selected the maximum UE of connecting line according to these mapping relations, sends adjacent cell load information request message to it, simultaneously the corresponding connecting line of deletion; Select the maximum UE of connecting line afterwards again in remaining mapping relations, send adjacent cell load information request message to it, the corresponding connecting line of deletion simultaneously finishes up to all connecting lines are deleted.
When this cell base station finds that this cell load is overweight, when reaching certain thresholding and need do load balancing, even without receiving that the load variations indicated value is 1 message, also can initiatively send adjacent cell load information demand signalling, request UE reports adjacent cell load information.The mode of the object UE of base station selected transmission signaling is identical with previously described process at this moment, and the load variations indicated value of just supposing all UE all is 1.
When UE finds that by measurement the signal of the dtr signal of this sub-district, adjacent sub-district is better, in the time of may switching, also can be initiatively to the base station transmit signals load information of adjacent sub-district preferably, and need not receive the adjacent cell load information demand signalling that send the base station by the time.The load information that UE initiatively sends has two kinds of forms: a kind of is foregoing concrete quantized value, a kind of is to do a whether judgement of access earlier according to the load quantized value of being surveyed, and the judgment value (1 bit) of access reports the base station as load information then.Wherein, second method can reduce the data volume of eating dishes without rice or wine, but requires UE that certain access judgement is arranged, and consistent with the access algorithm of base station.
