Embodiment
In mobile communications network; Along with growing requirement to data speed and covering; Traditional provides the method for access can not meet the demands with macro base station; Through the employing cell splitting, and, can be good at addressing this is that in hot zones or some low power base station of indoor deployment (Pico base station, Femto base station and Relay etc.).Because low power base station is a kind of base station equipment that is applied under family's indoor environment, working environment or other the little overlay environment, can make operator that high data rate, attractive business more cheaply are provided more.
But; The introducing of low power base station can cause interference in the system with respect to even more serious with layer network; For the interference on the control channel, become bottleneck with heterogeneous network work under the frequency, how effectively to avoid interference is the problem that needs solution; And can't be under the Macro+Femto scene in the prior art, the process of the subframe set of restriction is transmitted in realization alternately.
To the problems referred to above, the embodiment of the invention provides the method and apparatus that interference is avoided in a kind of heterogeneous system, with to schemes such as present time domain coordinate scheme and power controls, proposes a kind of mode of avoiding inter base station interference of monitoring through eating dishes without rice or wine.And under the Macro+Femto scene, also can effectively solve the interference problem that exists under the current Macro+Femto scene, effectively improve systematic function and data rate in the heterogeneous network.
To combine the accompanying drawing among the present invention below, the technical scheme among the present invention is carried out clear, intactly description, obviously, described embodiment only is a part of embodiment of the present invention, 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.
The embodiment of the invention one provides the method that interference is avoided in a kind of heterogeneous system, and this method is applied under the scene of Macro+Femto, and is as shown in Figure 3, and the method that this interference is avoided may further comprise the steps:
Step 301, the FeNB start, and set up synchronous with MeNB.
Wherein, this is set up synchronous process and comprises: FeNB through the CRS signal of monitoring MeNB keep with MeNB synchronously.
Step 302, FeNB obtains to receive and disturbs the subframe position of avoiding information to gather.
Concrete, after the FeNB start, can receive network management information from Network Management Equipment, comprise in this network management information and disturb the subframe position set (being that FeNB can avoid information through the interference that this subframe position set receives MeNB) of avoiding information corresponding.Wherein, the set of this subframe position is identical for MeNB and FeNB, and MeNB need send interference and avoid information on these subframe position, and FeNB need receive the interference of MeNB and avoids information on these subframe position, disturb and avoid.
Further; The network management information that Network Management Equipment needs to carry subframe position set (MeNB sends and disturbs the subframe position set of avoiding information) is notified to FeNB and MeNB; Send the information of avoiding of disturbing by MeNB according to this subframe position set, FeNB monitors the information of avoiding of disturbing according to this subframe position set.
Certainly, in the practical application, can also give FeNB and MeNB with subframe position set notice through other modes; For example, after MeNB is known the subframe position set, give FeNB with subframe position set notice by MeNB; Explanation no longer in detail in the embodiment of the invention is described for ease.
In the embodiment of the invention, after the FeNB start, can also in predefined subframe position set, receive and disturb the subframe position set of avoiding information corresponding from the reception of MeNB.Wherein, this predefined subframe position set can be selected arbitrarily according to actual needs, is perhaps defined in advance by agreement; This receive mode includes but not limited to receive the subframe position set of avoiding the information correspondence from the reception interference of MeNB with the mode that receives RRC signaling or system information.
In addition, in the practical application, can also predefined subframe position set be confirmed as to receive and disturb the subframe position set of avoiding information corresponding, repeat no more in the embodiment of the invention.
Step 303, FeNB receives the interference of MeNB and avoids information in this subframe position set.
In the embodiment of the invention, this interference avoids information to include but not limited to:
Subframe configuration information includes but not limited in this subframe configuration information: need transmit the subframe set of restriction, transmit the type (like almost blank or MBSFN subframe) of restriction etc.
Power control information, this power control information includes but not limited to: descending power Control Parameter, uplink power control parameter, power controlled target signal to noise ratio, uplink power control parameters optimization etc.
It should be noted that FeNB before information is avoided in the interference that receives MeNB in this subframe position set, MeNB need avoid information to send to FeNB interference in this subframe position set.
Concrete, the mode that MeNB avoids information to send to FeNB interference includes but not limited to:
MeNB avoids information to send to FeNB interference through RRC (Radio Resource Control, Radio Resource control) means of signaling; Perhaps,
MeNB avoids information to send to FeNB interference through the mode of system information (SIB/MIB information).
Corresponding, FeNB receives the interference of MeNB and avoids the mode of information to include but not limited in this subframe position set:
FeNB avoids information with the interference that receives RRC means of signaling reception MeNB in this subframe position set; Perhaps,
FeNB avoids information with the interference that the mode of receiving system information receives MeNB in the set of this subframe position.
FeNB is configured to MB SFN (Multimedia Broadcast multicastservice Single Frequency Network, multimedia broadcast multi-broadcasting business Single Frequency Network) subframe in this subframe set.
It should be noted that in the embodiment of the invention,, avoid information, also need the symbol shift of certain symbol between FeNB and the MeNB in order to make FeNB can obtain to disturb for TDD (Time Division Duplexing, time division duplex) system.For example; Suppose to have only a symbol in the control area of FeNB; The shift that two symbols are arranged between FeNB and the MeNB, the sketch map of symbol shift as shown in Figure 4, the RRC signaling or the system information that are configured to receive on the position of MBSFN subframe MeNB at FeNB obtain to disturb the information of avoiding.
Step 304, FeNB avoids information on corresponding subframe position, to transmit restriction according to interference.
Wherein, transmission restriction is meant that interference base station on some subframe position (for example, FeNB) limits the transmission of its particular channel, to avoid on this subframe by the interference of EVAC; Perhaps,
Interference base station is in the transmission of whole its particular channel of subframe limit, to avoid on this subframe by the interference of EVAC; Perhaps,
Interference base station is adjusted on the particular channel power on the subframe, to avoid on this subframe by the interference of EVAC.
Concrete, owing to avoid having carried information such as subframe configuration information, power control information in the information, then avoid information FeNB can transmit restriction according to interference in interference, give unnecessary details no longer in detail in this process embodiment of the invention.
In sum, through adopting above-mentioned processing procedure, information is avoided in the interference that promptly can on FeNB, obtain MeNB, and avoids information to transmit restriction according to interference, thereby the interference between realization FeNB and the MeNB is avoided.
In practical application, to disturb when avoiding the corresponding subframe position set of information to change if obtain, this method can also may further comprise the steps:
Step 305, the subframe position set of avoiding information corresponding is disturbed in the reception after confirming to change.
Wherein, Upgrade if desired and obtain to disturb when avoiding the corresponding subframe position of information to gather; Then MeNB can disturb the reception after changing and avoid the corresponding subframe position set of information to submit to Network Management Equipment through network management interface; Disturb the subframe position set of avoiding information corresponding by the reception after the definite variation of Network Management Equipment, and this information is sent to MeNB and FeNB.Certainly, in the practical application, Network Management Equipment also can be confirmed to change the back reception through other modes and disturb the subframe position set of avoiding information corresponding, repeats no more in the embodiment of the invention.
Perhaps; The subframe position set of avoiding information corresponding is disturbed in reception after MeNB confirms to change, and the reception before variation disturbs the reception of avoiding sending after changing through RRC signaling or system information on the corresponding subframe collection location of information to disturb the subframe position set of avoiding information corresponding.
Step 306, FeNB obtains to receive and disturbs the subframe position of avoiding information to gather.After obtaining the subframe position set, forward the interference that in the set of the subframe position after the renewal, receives MeNB in the step 303 to and avoid information.
In this step, FeNB obtains to receive and disturbs the mode of the subframe position set of avoiding information to include but not limited to:
(1) after the corresponding subframe position set of information is avoided in the reception interference after Network Management Equipment is confirmed to change, disturb the subframe position set notice of avoiding the information correspondence to give FeNB the reception after changing.
(2) MeNB disturbs the reception after avoiding will changing in the corresponding subframe position set of information to disturb the subframe position set notice of avoiding the information correspondence to give FeNB in current reception.
Concrete, after MeNB knew that the subframe position set of avoiding the information correspondence is disturbed in the reception after the variation, the subframe position set notice after MeNB can will change on current subframe position is gathered through RRC signaling or system information was to FeNB.The reception of FeNB after variation disturbed and avoided the corresponding subframe position set of information to obtain the information of avoiding of disturbing, and in corresponding subframe set, transmits restriction.
In practical application, to gather when changing if transmit the subframe position of restriction, this method can also may further comprise the steps:
Step 307, the subframe position set of transmitting restriction after confirming to change.
Wherein, When upgrading the subframe position set of transmitting restriction if desired; Then MeNB can submit to Network Management Equipment through network management interface with the subframe position set of transmitting restriction after changing; Confirm to transmit the subframe position set of restriction by Network Management Equipment, and this information is sent to MeNB and FeNB.Certainly, in the practical application, the subframe position set of transmitting restriction after Network Management Equipment also can be confirmed to change through other modes is repeated no more in the embodiment of the invention.
Perhaps, the needs after MeNB confirms to change transmit the subframe position set of restriction, and disturb the subframe position of avoiding sending after changing through RRC signaling or system information on the corresponding subframe collection location of information of transmitting restriction to gather in the FeNB reception.
It should be noted that; In the embodiment of the invention, transmit the reason that the subframe position set of restriction changes and include but not limited to: because the number of the MUE that is disturbed causes the subframe position set to change, the subframe position set changes, the mode through pre-planning makes the subframe position set change because traffic needs causes.
In order more clearly to set forth the technical scheme that the embodiment of the invention provides, be elaborated below in conjunction with concrete application scenarios.Should be with under the scene, (the Femto base station: FeNB) scene of coexistence is an example, wherein to have macro base station (MeNB) in the same area and to cover the picocell base station of hot zones; MeNB uses identical carrier wave with FeNB; Under this scene, EVAC is Femto, is Macro by EVAC.
Through the technical scheme that adopts the embodiment of the invention to provide, FeNB transmits restriction in the subframe position set of confirming, the MUE that is disturbed by FeNB can work on FeNB transmits the subframe set of restriction.
In the practical application; If quantity or the traffic carrying capacity of the MUE that is disturbed reduce; Then macro base station can be confirmed a subframe position set of transmitting restriction again, and reducing the number of subframes that FeNB transmits restriction, and the set of the subframe position after will upgrading is notified to FeNB.
Under the Another Application scene, (the Femto base station: FeNB) scene of coexistence is an example, wherein to have macro base station (MeNB) in the same area and to cover the picocell base station of hot zones; MeNB uses identical carrier wave with FeNB; Under this scene, EVAC is Femto, is Macro by EVAC.
In the practical application; Because the business of Femto system (for example has tidal effect; By day maybe business demand less, and waits the business demand amount of period more between the lights), promptly Femto need transmit the variation that the subframe position of restriction gathers and changes according to certain rule.Therefore, MeNB can be according to this tidal effect of Femto system, and according to the processing of pre-planning, the subframe position set of restriction is transmitted in adjustment, and gives FeNB with this subframe position set notice.
