Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
For above-mentioned purpose, the feature and advantage that make the embodiment of the invention can be more obviously understandable, the embodiment of the invention is done further detailed explanation below in conjunction with accompanying drawing and embodiment.
In the LTE system, the effect of reference signal (Reference Signal is called for short RS) not only can be accomplished the reduction presence of intercell interference, assists scheduling of resource, data demodulates reference, also can realize power control, synchronously adjustment and channel snr measurement etc.At present, the RS signal can be divided into demodulated reference signal and detection reference signal (Sounding reference signal is called for short SRS).Generally, UE is behind connecting system, and the SRS resource just may be distributed to UE in the base station, utilizes SRS to make the needs of RRM to satisfy the base station.
The problem that LTE exists edge customer to disturb, same, edge customer sends the problem that also there is presence of intercell interference in the SRS signal.But present technical scheme does not take into full account the problem of presence of intercell interference when carrying out the SRS resource allocation, possibly cause edge customer to increase the weight of in presence of intercell interference.
Such as, if adjacent base station has sent overload indication (Overload Indicator is called for short OI), show that overload has taken place the physical resource of this adjacent base station.In such cases, do not carry out the distribution of SRS resource if do not consider the information of physical resource overload, then possibly cause SRS in the base station (such as the enode eNB in the LTE system) the received signal quality variation or can't normally receive at all.
To above-mentioned technical problem, the embodiment of the invention provides the corresponding techniques scheme, will be described in detail below.
What be worth explanation is because there are corresponding relationship in base station and sub-district, in the description of the embodiment of the invention, mainly to be description object with the base station; Because there are corresponding relation in UE and user, in the description of the embodiment of the invention, mainly be description object again with UE.
In actual scene, OI is sent in the base station can comprise following dual mode:
Mode one: when there was overload in the physical resource that only UE uses in the base station, OI was just sent to adjacent base station in this base station, and was shown in which PRB or which subband has overload at this OI middle finger.
Mode two: whether the physical resource no matter UE uses in the base station exists overload, and OI is all sent according to predefined frequency in the base station.Certain PRB or the subband of this base station of explanation transship in this OI, and perhaps certain PRB or the subband of this base station of explanation do not transship in OI.
To mode two, when the OI that this base station receiving neighbor bs sends, at first need screen the OI that receives this base station, confirms that the indicated particular content of this OI is to take place to transship or do not transship at certain PRB or subband.If confirm that the indicated particular content of OI is to transship at certain PRB or subband, then subsequent operation is carried out in this base station.
Explanation in subsequent implementation example of the present invention, is that example is described with mode one mainly for ease.
One embodiment of the invention provides a kind of method for managing resource.In embodiments of the present invention, be that example is described mainly with the LTE system.
Fig. 1 is one embodiment of the invention method flow diagram.As shown in Figure 1, this method mainly comprises:
In this step, the overload indication OI that this base station receiving neighbor bs sends, this OI indication physical resource transships;
In the LTE system, can send OI mutually between the adjacent base station, the OI of the base station transmission that is adjacent may be received in a base station.Explanation for ease receives that with one of them the base station of adjacent base station transmission OI is this base station in embodiments of the present invention, and other base stations of sending OI to this base station are adjacent base station.It is understandable that this base station and adjacent base station are corresponding.
In the present embodiment, the adjacent base station that this base station receives can comprise to the content of the OI that send this base station: send the Base Station Identification of the adjacent base station of this OI, and the generation of this adjacent base station overload physical resource.This physical resource can be: PRB or subband (sub band).
Send among the OI of this base station at adjacent base station, comprise the physical resource that overload takes place this adjacent base station,, have the user equipment (UE) of the physical resource that uses this overload, can think that then this OI is effective OI for this UE of this base station if in this base station.In addition, the UE of so-called base station is appreciated that to the UE of this base station as serving BS.
In this step, the OI that need send the adjacent base station that this base station receives judges, judges the satisfied preset thresholding of effective OI to the UE of this base station.
In this step,, if in step 120, judge that effective OI of this UE satisfies preset thresholding, then the detection reference signal SRS of this UE of this base station adjustment according to the judged result of step 120.
In the present embodiment, if the result of the judgement of step 120 is satisfied preset thresholdings of effective OI of this UE, message also can be sent to adjacent base station in this base station, triggers adjacent base station and carries out the adjustment of SRS resource.
In the present embodiment, whether effective OI of this base station UE is satisfied preset thresholding judge, according to the SRS of this UE of judged result adjustment, the SRS signal disturbs between the base station to reduce.Disturbing under the situation about reducing, the SRS signal quality that base station side receives is improved, thereby has improved the performance of communication system on the whole.
Another embodiment of the present invention provides a kind of method for managing resource, and Fig. 2 is another embodiment of the present invention method flow diagram.As shown in Figure 2, this method mainly comprises:
Wherein, concrete method of reseptance can be referring to step 110;
In receiving scene; This base station can not receive the OI that adjacent base station sends; Also can receive the overload indication that an adjacent base station sends; Perhaps receive the overload indication that a plurality of adjacent base stations send simultaneously, at first receiving the OI that an adjacent base station sends with this base station in the present embodiment is that example describes;
In the present embodiment, suppose that base station A is this base station, receives the OI that adjacent base station B sends.
It is understandable that, from the method for screening the effective OI for the UE of this base station the OI that this base station receives with step 120;
In this step, can be whether to judge effective OI number of in preset time T 1, receiving greater than the first preset thresholding, this preset time T 1 can be set as required;
The preset thresholding of effective OI of supposing the UE of base station A is 5.If the number of effective OI of the UE1 that the base station B that base station A receives sends is 6, judge that then effective OI of UE1 among the OI satisfies preset thresholding in time T 1; If the number of effective OI of the UE1 that the base station B that base station A receives sends is 4, judge that then effective OI of UE1 among the OI does not satisfy preset thresholding in time T 1.
In this step,, then adjust the detection reference signal SRS of this UE if the result who judges is the satisfied preset thresholding of effective OI of this UE (such as UE1).The interference of the physical resource of overload takes place to reduce base station A and base station B at this in the SRS of the UE1 that OI was directed against that base station A adjustment base station B sends.
Usually; When base station assigns SRS resource; The SRS parameter that is provided with can comprise: initial subcarrier, initial Physical Resource Block (PRB), SRS sending duration, SRS send parameter such as cycle, transmitted power parameter, frequency domain resource position, cyclic shift and whether this UE enables frequency hopping etc.; The configuration of these parameters is normally relevant with UE, and by the semi-static configuration of high level.In the technical scheme of the embodiment of the invention, can change these parameters of this UE.Wherein, parameters such as the transmitted power parameter of SRS, frequency domain resource position, cyclic shift are bigger to the SRS influence of UE.
In this step; Can send message to the UE that uses the physical resource that overload takes place through air interface; Triggering this UE adjustment influences the parameter of SRS resource, and for example: this sub-district idle message of base station configuration can be specific messages radio bearer configuration (RB Config) message or radio resource control (Radio Resource Control; Abbreviation RRC) (Connect Reconfig) message is reshuffled in the connection in, triggers UE and carries out the adjustment of SRS resource.
The adjustment of SRS resource can be carried out to trigger UE through send different idle messages to this UE in this base station, and concrete idle message can be one of following first idle message, second idle message or the 3rd idle message, perhaps its combination in any.
Wherein, first idle message can be to trigger the transmit power parameter that this UE reduces the SRS of UE self, reduces the message of the physical resource of the shared generation overload of this UE; Second idle message can be the frequency domain resource position of triggering the SRS of this UE adjustment UE self, makes the position of the frequency domain resource that this UE of this base station uses be different from the message of the position of the frequency domain resource that overload takes place; The 3rd idle message can be the message of cyclic shift parameter that triggers the SRS of this UE adjustment UE.As an example, in the scheme of the embodiment of the invention, can preferentially reduce the transmit power parameter (such as the part transmitting power biasing of, SRS, its adjustment step-length can be confirmed according to agreement) of SRS.If the transmitting power of current SRS has been minimum, then can not continue to reduce, in such cases, can select to adjust the frequency domain resource position of SRS resource or the cyclic shift parameter of SRS.In other words, can preferentially send first idle message, under the irreducible situation of SRS transmitting power, redispatch second idle message or the 3rd idle message.
In addition, it is understandable that first idle message, second idle message or the 3rd idle message; When concrete the realization; Can use with a kind of message, perhaps connect reconfiguration message such as the radio bearer configuration, difference is that the configuration parameter that carries in this message is different.
In the present embodiment; Before sending the SRS of this UE of idle message adjustment to this UE; Can also comprise a step: judge in preset time T 2, whether to send identical idle message; If the result who judges did not send identical idle message in preset time T 2, then send idle message.If the result who judges does not then repeat to send this idle message in preset time T 2, to have sent identical idle message, but can send the idle message different with this idle message that had sent.Wherein, time T 2 can be set as required.
Do not satisfy preset thresholding if the result who judges is effective OI of this UE, then execution in step 240;
In this step, according to the judged result of step 220, base station A does not adjust the SRS of UE1.Base station A can send message to base station B through X2 mouth or S1 mouth, triggers the physical resource that overload takes place among base station B adjustment its this base station B, such as, can trigger the SRS of the UE of base station B adjustment base station B.Wherein, base station B is similar with the method that base station A adjusts UE1 to the method for adjustment of the SRS of the corresponding UE of physical resource that overload takes place among the B of base station.Perhaps, base station A also can send message to base station B through X2 mouth or S1 mouth, informs that B base station, base station A does not carry out the resource adjustment to the SRS of the UE2 among the A of base station.Again perhaps, base station A also can not carry out any operation.
More than be that example is described with the mutual of this base station and an adjacent base station, and the judgement of step 220 relatively is that example is described with effective OI number and the thresholding that receives in the Preset Time only.
It is understandable that, in the present embodiment, also can be that this base station receives the OI that a plurality of adjacent base stations send, and it is similar that its implementation and this base station receive the OI of an adjacent base station transmission.Suppose that base station A receives the OI that two adjacent base stations (base station B and base station C) send respectively in step 210; In step 220, the OI that then respectively base station B and base station C is sent judges.And according to judged result execution in step 230 or step 240.
And the step 220 in the present embodiment also can be: whether judge effective OI number of in preset time T 1, receiving greater than the first preset thresholding, and whether effective OI number of receiving continuously is greater than the second preset thresholding.
For instance, the preset thresholding to the effective OI of UE among the A of base station in time T 1 is 5, and the preset thresholding of the effective OI that receives continuously is 4.Suppose in time T 1, to receive that effective OI number that base station B sends is 6, effective OI number of receiving continuously is 4, judges that then effective OI of the base station B transmission that base station A receives satisfies preset thresholding, execution in step 230.Suppose in time T 1, to receive that effective OI number that base station B sends is 6, effective OI number of receiving continuously is 3, judges that then effective OI of the base station B transmission that base station A receives does not satisfy preset thresholding, execution in step 240.If base station A receives the OI that a plurality of adjacent base stations send simultaneously, then the OI to each adjacent base station judges respectively, and carries out subsequent step according to different judged results.
In the present embodiment, whether effective OI of this base station UE being satisfied preset thresholding judge, is under the situation that is in judged result, and through sending the SRS that idle message triggers adjustment this base station UE to UE, the SRS signal disturbs between the base station to reduce; Judged result for situation not under, can send message to adjacent base station, trigger adjacent base station and carry out the resource adjustment, inform that perhaps this base station of adjacent base station do not carry out the resource adjustment to the SRS of UE, perhaps, any operation also can not carried out in this base station.No matter it is understandable that, be that this base station or adjacent base station are adjusted the SRS resource, can reduce SRS signal interference between the base station.And disturbing under the situation about reducing, the SRS signal quality that base station side receives is improved, thereby has improved the performance of communication system on the whole.
In addition, in the present embodiment, can be before sending idle message to UE; Whether judgement sent identical idle message in Preset Time, guarantee in the regular hour, can not carry out the adjustment (but allowing dissimilar adjustment) of same type continuously to the SRS resource of same UE, to suppress excessively to utilize a certain mode to carry out re-adjustments; Cause service exception; Simultaneously, also controlled the transmission frequency of idle message, reduced excessive use interface-free resources.
