Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
It is pointed out that the embodiment of the present invention is applicable to all employing ABS or MBSFN reduces the scene of disturbing.That is, can be applicable to the wireless communication system of various standards, and wherein the base station of phase mutual interference can be that the base station of same type can be also dissimilar base station in communication system.For convenience of description, the embodiment of the present invention be take LTE-A wireless communication system and is set forth as example, but the invention is not restricted to this, and the embodiment of the present invention is equally applicable to other wireless communication system.
In LTE-A wireless communication system, the first base station and the second base station have configured frequency spectrum resource identical or that part is identical, therefore, between the first base station and the second base station, can produce phase mutual interference, interference coordination will be carried out in the first base station and the second base station, in order to allow the UE of the first base station service normally work, the second base station has adopted the scheme of ABS scheme or MBSFN subframe.
As shown in Figure 1, the method for the measurement resource indication that the embodiment of the present invention provides, comprising:
Step 101, the first base station is the type that UE is identified for the reference signal measured, and generates type indication information according to the type for the reference signal measured of determining, wherein, the described type for the reference signal measured is CSI-RS or CRS;
In LTE-A wireless communication system, UE carries out the reference signal that the measurement of RLM, RRM and CSI etc. can adopt and comprises two types, is respectively CSI-RS and CRS.Therefore, first the first base station need to be identified for the type of the reference signal of measurement for UE selection, concrete, the first base station determines that by the information such as transmission mode, feedback model or channel conditions of the UE serving according to oneself which kind of reference signal UE adopts measure, be identified for the type of the reference signal of measurement, to guarantee the accuracy of measurement result.
Step 102, the first base station knows that the second base station is for the approximate empty subframe ABS of interference coordination or the configuration cycle of MBSFN subframe.
In the embodiment of the present invention, in order to reduce the interference to the first base station, the second base station has adopted the scheme of ABS scheme or MBSFN subframe to carry out interference coordination.Setting by advance or by wired or wireless interface between the first base station and the second base station, the first base station can know that the second base station is for the ABS of interference coordination or the configuration information of MBSFN subframe, described configuration information comprises the configuration cycle for the ABS of interference coordination or MBSFN subframe, and whether identify each subframe within described configuration cycle be indication pattern of ABS or MBSFN subframe etc., the first base station can know that the second base station is for the configuration cycle of interference coordination ABS or MBSFN subframe.
Step 103, the first base station, according to the transmission cycle of the CSI-RS of described configuration cycle and the configuration of the first base station, is determined and is measured the indication cycle;
Wherein, measuring the indication cycle is the least common multiple of the transmission cycle of described configuration cycle and described CSI-RS.
In abovementioned steps 102, the first base station has known that the second base station is for the ABS of interference coordination or the configuration cycle of MBSFN subframe, and the transmission cycle of configured CSI-RS can be known in the first base station, for example the transmission cycle of CSI-RS is 5,10,20,40 or 80ms.Therefore, evaluation computing can be carried out according to the transmission cycle of the CSI-RS of described configuration cycle and configuration in the first base station, obtains both least common multiples, measures the indication cycle.The measurement resource that the first base station is assigned to UE is that to measure the indication cycle be chronomere, and the measurement resource of the specified UE of giving in the first base station is within the scope of a time span of measuring the indication cycle, the measurement resource that UE can use.In the first base station, indicate to UE this to measure in the time interval that indication information comes into force before starting to come into force to the measurement indication information of next update, the measurement resource that the first base station is assigned to UE in described time interval is that to measure the indication cycle be that unit periodically repeats according to the measurement resource of measuring in the indication cycle.
What note here is, in an embodiment of the present invention, measure the indication cycle not based in the type of reference signal, no matter the type of the definite reference signal of abovementioned steps 101 is CSI-RS or CRS, the determined measurement indication cycle is the second base station for the least common multiple of the transmission cycle of the CSI-RS of the ABS of interference coordination or the configuration cycle of MBSFN subframe and the configuration of the first base station herein, that is the measurement indication cycle that the measurement indication cycle that is CSI-RS for the reference signal measured is CRS with reference signal for measuring is identical.And definite mode of measuring the indication cycle is in common knowledge by UE and the first base station, UE receives after the indication of the first base station, can calculate or know the measurement indication cycle of this indication.
Step 104, the first base station is according to described configuration cycle and measure the indication cycle generation measurement resource indication information;
Wherein, the length of measuring resource indication information is X bit, and X equals the described business for the transmission cycle of reference signal measured and the least common multiple of described configuration cycle and the described transmission cycle for the reference signal measured,
X=least common multiple (for the transmission cycle of the reference signal measured, the second base station is for the ABS of interference coordination or the configuration cycle of MBSFN subframe)/for the transmission cycle of the reference signal measured.
Available measurement subframe of measuring in the indication cycle of X bit indication is used in the first base station, concrete, if while being CSI-RS for the reference signal of measuring, measuring the described X bit of resource indication information and indicate respectively whether an X subframe measuring transmission CSI-RS in the indication cycle is available measurement subframe;
If while being CRS for the reference signal of measuring, because being 1ms, the transmission cycle of CRS (do not consider TDD (Time Division Duplexing here, time division multiplexing) system uplink subframe can not be transmitted the situation of CRS), the numerical value of X equals the second base station for the ABS of interference coordination or the configuration cycle of MBSFN subframe, thereby the integral multiple that the value of measuring the indication cycle is X, now, described X bit indicates respectively whether the subframe of transmitting CRS in a front X subframe of measuring in the indication cycle is available measurement subframe; Now, in the measurement indication cycle, in remaining subframe, available measurement subframe is carried out periodicity repetition according to the available measurement subframe of indicating in front X the subframe of measuring in the indication cycle.
Further, if while being CSI-RS for the reference signal of measuring, to measure in the indication cycle for one, the number of sub-frames that CSI-RS may be transmitted in the first base station is X, therefore, X bit can indicate whether an X subframe measuring transmission CSI-RS in the indication cycle is available measurement subframe;
And when the reference signal for measuring is CRS, because the transmission cycle of CRS is 1ms, a subframe is 1ms, establishing and measuring the value in indication cycle is Y, known according to abovementioned steps 103, the integral multiple that Y is X.Measure in the indication cycle for one, Y subframe can be transmitted in the first base station, and the number of sub-frames that may transmit CRS is similarly Y, Y subframe can be expressed as the set of an integer X subframe, and therefore, X bit can represent whether the subframe of middle transmission CRS of the front X subframe of Y subframe is available measurement subframe, due to the Y integral multiple that is X, therefore, in Y subframe, in remaining subframe, available measurement subframe is carried out periodicity according to the available measurement subframe of indicating in a front X subframe and is repeated.
Here it is pointed out that in the embodiment of the present invention, is X bit although measure the length of resource indication information, and the significant bit length that is used to indicate available measurement subframe in X bit can be X bit, also can be less than X bit.When described significant bit length is less than X bit, measuring the remaining bits except significant bit in the X bit of indication information can be undetermined or specify other Special Significance, and the present invention does not limit this.
Concrete, for FDD (Frequency Division Duplexing, frequency division multiplexing) system, the significant bit length of measuring resource indication information is X bit, and for TDD system, the significant bit length of measuring resource indication information can be X bit, and, because the sub-frame of uplink of TDD system can not transmit CRS, therefore, when the reference signal for measuring is that CRS and the second base station are while adopting ABS to carry out interference coordination, the significant bit length of the measurement resource indication information of TDD system can be the poor of sub-frame of uplink number that X and the first base station configure in the time span of Xms, when the reference signal for measuring is CRS and the second base station while adopting MBSFN subframe scheme to carry out interference coordination, the significant bit length of TDD systematic survey resource indication information can be the poor of number that sub-frame of uplink number that X and the first base station configure in the time span of Xms and the second base station can not be configured to MBSFN subframe in the time span of Xms.
Concrete, step 104 can realize by following steps:
First, the first base station knows whether the second base station identifies each subframe for the ABS of interference coordination or in the configuration cycle of MBSFN subframe be the indication pattern of ABS or MBSFN subframe;
By wired or wireless interface between the second base station and the first base station, the first base station can know that the second base station is for the ABS of interference coordination or the configuration information of MBSFN subframe, described configuration information comprises the configuration cycle for the ABS of interference coordination or MBSFN subframe, and whether identify each subframe within described configuration cycle be the indication pattern of ABS or MBSFN subframe, the first base station can know in described configuration cycle, whether each subframe of sign is the indication pattern of ABS or MBSFN subframe;
The second base station employing ABS scheme of take is carried out interference coordination as example, and the second base station that the first base station is known is T for the configuration cycle of the ABS of interference coordination aBS, indication pattern can Bit String (b1, b2 ..., b tABS) represent, bit bi (i get interval [1, T aBS] within integer) be used to indicate this T aBSwhether interior i subframe is configured to ABS subframe.As bi value 1 represents that i subframe is configured to ABS subframe, value is that i subframe of 0 expression is not configured to ABS subframe, and vice versa.Apparently, the indication pattern that the first base station is known is not limited to aforesaid way, also can have whether each subframe in a period of sub-frame of other indications is the indication pattern of ABS subframe.
Afterwards, the first base station, according to measuring indication cycle, configuration cycle and described indication pattern, is determined at one and is measured the sub-frame resources that is configured to ABS or MBSFN subframe in the indication cycle; The first base station is according to measuring indication cycle, the definite type for reference signal and transmission cycle thereof, determines that one is measured in the indication cycle transmission this determines the sub-frame resources of the reference signal of type;
The first base station can be according to known ABS or MBSFN configuration information, determine in the configuration cycle, which subframe of the second base station has been configured to ABS or MBSFN subframe, and then determines that one was measured in the indication cycle, and those subframes of the second base station have been configured to ABS or MBSFN subframe.
Meanwhile, the first base station can be according to the transmission cycle of the reference signal of determined type, determine that one was measured in the indication cycle, those subframes transmission of the first base station the reference signal of definite type.
Afterwards, the first base station according to described in be configured to the common factor of sub-frame resources of reference signal of the definite type of sub-frame resources and transmission institute of ABS or MBSFN subframe, determine an available measurement subframe in the measurement indication cycle;
When the reference signal for measuring is CSI-RS, ABS or the MBSFN sub-frame resources crossing subframe of the first determined available measurement subframe in base station for configuring with the second base station in the sub-frame resources of transmission CSI-RS, when the reference signal for measuring is CRS, ABS or the MBSFN sub-frame resources crossing sub-frame resources of determined available measurement subframe for configuring with the second base station in the sub-frame resources of transmission CRS.Here and in the present invention, it is identical wholly or in part that the common factor of subframe or subframe intersect the transmission time meaning between subframe.
Like this, the first determined available measurement resource in base station.In the time of can making UE measure, for the resource of measuring, the limited interference of ABS or MBSFN sub-frame resources will be only subject to, can effectively reduce interference effect, when even the UE of the first base station service is subject to strong jamming, UE still can measure accurately, can improve the accuracy of measurement result, guarantee the proper communication between UE and base station.
Finally, the first base station, according to a described available measurement subframe of measuring in the indication cycle of determining, generates and measures resource indication information.
Step 105, the first base station sends described type indication information and described measurement resource indication information to UE.
UE can be according to the indicated reference signal type of the type indication information of reference signal, in the indicated resource of resource indication information, measures.
Like this, can reduce interference effect, guarantee the accuracy of measurement result.
Concrete, first the first base station can send described type indication information by UE dedicated signaling or broadcast signaling to UE, then by UE dedicated signaling or broadcast signaling, to UE, sends described measurement resource indication information; Or send described type indication information simultaneously and measure resource indication information to UE by UE dedicated signaling or broadcast signaling.The first base station can send or while transmission types indication information and measurement resource indication information successively to UE,
Because the first base station sends to the measurement resource indication information of UE, be to measure the indication cycle as the chronomere of indication, the first base station need to guarantee to measure the validity of resource indication information, UE can determine available measurement subframe according to measuring resource indicator message, in other words, measure in the indication cycle, need to comprise available measurement subframe for one.
Therefore, further, before step 103, the measurement indicating means that the embodiment of the present invention provides also can comprise:
The first base station knows whether the second base station identifies each subframe for the ABS of interference coordination or in the configuration cycle of MBSFN subframe be the indication pattern of ABS or MBSFN subframe;
The first base station is according to described configuration cycle and indication pattern, adjust transmission cycle and the skew of CSI-RS, using guarantee UE adopt CSI-RS as measure reference signal time, measure in the indication cycle for one and comprise the measurement subframe that at least one is available, to guarantee to using, measure the indication cycle as the validity of the resource indication information of the chronomere of indication, further guarantee the precision of follow-up measurement.
Below by specific embodiment, the method for measurement resource indication of the present invention is further described.
As shown in Figure 2, be a specific embodiment of the method for measurement resource of the present invention indication, in the present embodiment, the second base station is for the configuration cycle T of the ABS of interference coordination aBSfor 8ms, a length is T aBStime window in to be numbered 0 sub-frame configuration be ABS.The present embodiment comprises:
Step 201, the first base station is that the reference signal that UE is identified for measuring is CSI-RS, and the type indication information of generating reference signal.

Step 202, T is known in the first base station aBS, and at T aBSwhether each subframe of interior sign is ABS indication pattern;
Here, indication pattern can be expressed as (1,0,0,0,0,0,0,0,0), means a T aBSin to be numbered 0 sub-frame configuration be ABS, other subframes are non-ABS.
Step 203, the first base station is according to T aBSand T cSI-RS, determine and measure the indication cycle;
Measuring the indication cycle is T aBSand T cSI-RSleast common multiple, in the present embodiment, be 40ms.
Step 204, the first base station is according to measuring indication cycle, T aBS, and indication pattern, determine that is measured a sub-frame resources that is configured to ABS in the indication cycle;
One is measured the indication cycle is 40ms, and 4 frames can be transmitted in the second base station, and T aBSfor 8ms, and each T aBSin, be numbered 0 subframe and be configured to ABS, therefore, the first base station can determine that measuring the set that is configured to the sub-frame resources of ABS in the indication cycle for one is { 0,8,6,4,2}, represents that one was measured in the indication cycle, and 2 work song frames of 6 work song frames of 0 work song frame of first frame of the second base station and 8 work song frames, second frame, 4 work song frames of the 3rd frame, the 4th frame are configured to ABS.
Step 205, according to measuring indication cycle and T cSI-RS, determine a sub-frame resources of measuring transmission CSI-RS in the indication cycle;
One is measured the indication cycle is 40ms, and 4 frames can be transmitted in the first base station, and T cSI-RSfor 5ms, and each T cSI-RSin, be numbered 0 subframe transmission CSI-RS, therefore, the first base station can determine that a set of measuring the sub-frame resources of transmission CSI-RS in the indication cycle is { 0,5,0,5,0,5,0,5}, represent that one was measured in the indication cycle, 0 work song frame of 0 work song frame of 0 work song frame of 0 work song frame of first frame of the first base station and 5 work song frames, second frame and 5 work song frames, the 3rd frame and 5 work song frames, the 4th frame and 5 work song frames transmission CSI-RS.
Here note, step 204 and 205 order are not limit, and can carry out simultaneously, can carry out successively yet.
Step 206, available measurement sub-frame resources, according to the common factor that is configured to the sub-frame resources of ABS and the sub-frame resources of transmission of reference signals, is determined in the first base station.
The set that is configured to the sub-frame resources of ABS in the measurement indication cycle is { 0,8,6,4,2}, a set of measuring the sub-frame resources of transmission CSI-RS in the indication cycle is { 0,5,0,5,0,5,0,5}, both common factors are that { 0}, represents that the subframe of the first base-station transmission CSI-RS and subframe that the second base station is configured to ABS only have 1 time in the indication cycle to intersect measuring, and the first base station is measured in the subframe of transmitting CSI-RS in the indication cycle and to be configured to the crossing subframe of the subframe of ABS with the second base station and to be defined as available measurement sub-frame resources one.
Step 207, the first base station, according to being the available measurement sub-frame resources of the definite use of UE, generating and measures resource indication information;
Concrete, formula can be passed through in the first base station:
Least common multiple (T aBS, T cSI-RS)/T cSI-RS
The significant bit length that obtains resource indication information is 8 bits, and makes each bit value correspond respectively to one of indication to measure whether 8 subframes that carry transmission CSI-RS in the indication cycle are available measurement subframe.
Because measuring the indication cycle is 40ms, therefore, at one, measure in the indication cycle, the first 40 of base-station transmissions subframe, wherein, the subframe that may transmit CSI-RS has 8.Therefore, the first base station adopt the Bit String that length is 8 (c1, c2 ...., c8) as type indication information, each bit value corresponds respectively to one of indication and measures whether 8 subframes that carry transmission CSI-RS in the indication cycle are available measurement subframe; For example, it is 1 that ci bit can be set, and is illustrated in and measures in the indication cycle, and UE can measure in the subframe of i transmission CSI-RS.As ci bit can be set, be 0, be illustrated in and measure in the indication cycle, UE cannot measure in the subframe of i transmission CSI-RS.In the present embodiment, measure resource indication information and be expressed as (1,0,0,0,0,0,0,0), be illustrated in and measure in the indication cycle, UE can measure in the subframe of the 1st transmission CSI-RS.
Step 208, sends transmission types indication information and measures resource indication information to UE, so that UE, according to the type of the indicated reference signal of described type indication information, measures in the available measurement subframe of described measurement resource indication information indication.
The measurement subframe adopting due to UE is only subject to the limited interference of ABS subframe, so can reduce interference effect, guarantees the accuracy of measurement result.
As shown in Figure 3, be a specific embodiment of the method for measurement resource of the present invention indication, in the present embodiment, the second base station is for the configuration cycle T of the ABS of interference coordination aBSfor 8ms, a length is T aBSin time window, being numbered 0 and 4 sub-frame configuration is ABS.The present embodiment comprises:
Step 301, the first base station is that the reference signal that UE is identified for measuring is CSI-RS, and the type indication information of generating reference signal.
