The present invention will be described with specific embodiment below:
The objective of the invention is auxiliary descending power control algorithm, solve descending covering problem.The core content of this patent is divided into two aspects; At first be to add the existence that new agreement flow process detects the UE of free time (IDLE) state that the signal that receives HeNB disturbs through cell selecting or reuse adoption process; Dispose the existence of the UE under connection (CONNECTED) state that signal that suitable measurement and report event detection receives HeNB disturbs; Thereby triggering power control, secondly is how power control back base station power resets.These two processes can both be controlled by auxiliary power, improve the covering performance and the data rate of hierarchical network.
Concrete Poewr control method can be referring to the embodiment 1 in the patent " a kind of UE assists method for controlling downlink power ".The triggering of power control can be that macro base station is initiated, and also can independently be initiated by Home eNodeB.
Embodiment one:
In the present embodiment; The UE that HeNB utilizes cell selecting or reuse adoption process detection disturbed by the signal of this HeNB; And then trigger power and control; The UE that is disturbed possibly be the UE (MUE) of macro base station service, also possibly be the UE (HUE) under near the CSG ID that the has HeNB different with the CSG ID of this HeNB.
In the existing protocol flow process, cell selecting or gravity treatment are user's behaviors, do not have the communication between user and the base station; The base station does not know whether the user resides in the sub-district of oneself; In order to protect the user under the IDLE state, need to introduce new agreement flow process, add the resident connectivity request message of UE to HeNB; Or UE is to the indication information of HeNB, to tell base station oneself nearby.Handling process is specific as follows:
Step 1: be in UE measure R SRP in cell selecting or reuse adoption process of IDLE state, the sub-district that search signal is the strongest supposes that the strongest sub-district of signal that this UE searches is the sub-district of HeNB near;
After step 2:UE oneself is unauthorized CSG (non-CSG) user of HeNB according to the CSG ID in the system message or from the PCI judgement that synchronizing signal parses; Send connection request or had indication information to HeNB by interference user; UE can get rid of the selection that HeNB continues next base station simultaneously, up to the sub-district that resides in certain base station;
After step 3:HeNB receives connection request that non-CSG user sends or had indication information by interference user, confirm that current existence receives the non-CSG user that the signal of this HeNB disturbs;
Step 4:HeNB independently triggers power control according to trigger condition, reduces the signal transmission power of this HeNB.
Embodiment two:
In the present embodiment,, introduce new agreement flow process, add UE and the report process and the resident base station of (being the serving BS of UE) arrive the information process of transmitting of HeNB to resident base station in order to protect the user under the IDLE state.Concrete handling process is following:
Step 1: the UE measure R SRP in cell selecting or reuse adoption process that is in the IDLE state; The sub-district that search signal is the strongest; If this UE searches the sub-district that the strongest sub-district of signal is near HeNB; Then UE can get rid of the selection that HeNB continues next base station, up to the sub-district that resides in certain base station;
Step 2:UE sends measurement control configuring request to resident base station after oneself being the non-CSG user of HeNB according to the CSG ID in the system message or from the PCI judgement that synchronizing signal parses;
Step 3: resident base station receives measures the control configuring request, to the control information of UE allocating and measuring; Comprise measuring amount and measurement and report trigger condition that UE need measure in the measuring control information; When confirming to satisfy the measurement and report trigger condition according to the measuring amount that measures, UE can be carried at the measuring amount that measures and report resident base station in the measurement report;
Step 4:UE receives the laggard behaviour part of measuring control information and measures;
Step 5: if satisfy the measurement and report trigger condition, UE reports resident base station with measurement report;
Step 6: resident base station sends to HeNB through interface with measurement report;
Because the sub-district of HeNB is the strongest sub-district of signal that UE searches; Therefore the sub-district of HeNB necessarily appears in the adjacent cell list of UE; Therefore, UE is bound to the sub-district of HeNB is measured according to measuring control information, also will comprise the information of the sub-district of HeNB in the last measurement report of UE; So, resident base station just can send to this HeNB with measurement report through interface;
Step 7:HeNB confirms that according to the measurement report that receives current existence receives the non-CSG user of the signal interference of this HeNB, and then triggers power control, reduces the signal transmission power of this HeNB.
Embodiment three:
In the present embodiment, HeNB utilizes measurement event such as A3, A4 to detect the UE (comprising unauthorized MUE or HUE) that disturbed by this HeNB signal on every side, and after affirmation had UE possibly receive the signal interference nearby, HeNB triggered power and controls.Concrete handling process is following:
Step 1: when the measurement and report trigger condition was satisfied, UE sent measurement report to source base station (being the serving BS of UE);
Step 2: source base station directly sends to target HeNB and is had indication information by interference user, can realize the transmission of information through X2 mouth or S1 mouth;
The target HeNB here is meant the corresponding HeNB of HeNB sign that carries in the measurement report; If the information of not carrying HeNB in the measurement report then need not carried out this step and subsequent step.
Step 3:HeNB receives and is had indication information by interference user, confirms the non-CSG user that current existence is disturbed by the signal of HeNB;
Step 4:HeNB triggers power control, reduces the signal transmission power of this HeNB.
Embodiment four:
In the present embodiment; Only detect the existence of the UE (comprising unauthorized MUE or HUE) that receives the interference of HeNB signal through cell selecting/reuse adoption process and measurement report; Sometimes may cause more frequent power adjustment; Can take all factors into consideration some other condition, the condition that power control is triggered further limits.Concrete handling process is following:
Step 1: when the measurement and report trigger condition was satisfied, UE sent measurement report to source base station (being the serving BS of UE);
Step 2: source base station receives measurement report, confirms the signal level of interference of HeNB to UE through the metrical information to HeNB of carrying in the measurement report, and the information of this signal level of interference is sent to HeNB; Perhaps, source base station will be used for confirming that the relevant information of this signal level of interference sends to HeNB, confirm the signal level of interference of HeNB to UE by HeNB, and information is sent and can be realized through X2 mouth or S1 mouth;
Here; Can confirm the signal level of interference of HeNB according to the HeNB that carries in the measurement report corresponding RSRQ and/or RSRP information to UE, for example, if the value of RSRP is higher than predefined RSRP threshold value; Then the signal level of interference is high, otherwise the signal level of interference is low; Again for example, if the value of RSRQ is higher than predefined RSRQ threshold value, then the signal level of interference is high, otherwise the signal level of interference is low; Again for example, be higher than predefined RSRQ threshold value if the value of RSRP is higher than the value of predefined RSRQ threshold value and RSRQ, then the signal level of interference is high, otherwise the signal level of interference is low.
Step 3:HeNB then determines whether to exist the non-CSG user of the signal interference that receives this HeNB if receive the information of signal level of interference according to the signal level of interference, if, then trigger power control, reduce the signal transmission power of this HeNB;
If HeNB receive is used for confirming the relevant information of this signal level of interference, then confirms the signal level of interference of HeNB to UE according to this relevant information, confirms that method and source base station confirm that HeNB is identical to the method for the signal level of interference of UE; The HeNB non-CSG user that determines whether to exist the signal that receives this HeNB to disturb according to the signal level of interference then, if, then trigger power control, reduce the signal transmission power of this HeNB.
Here; According to the signal level of interference determine whether to exist the non-CSG user that the signal that receives this HeNB disturbs method can for: if the signal level of interference is for high; Then confirm to exist the non-CSG user of the signal interference that receives this HeNB; If the signal level of interference is low, then confirm not exist the non-CSG user of the signal interference that receives this HeNB.
Embodiment five:
In the present embodiment, judge the unauthorized CSG user's of the signal interference that receives HeNB existence through adjusting the A3 event detection, information is sent and is realized through X2 mouth or S1 mouth.Concrete handling process is following:
The serving BS of step 1:UE can be adjusted parameter in the A3 incident before the configuration to UE configuration A3 incident, triggers thresholding to reduce measurement and report, for example improves the deviant (offset) in the corresponding measurement and report trigger condition of A3 incident;
Step 2:UE measuring adjacent cells information;
Step 3: if satisfy the corresponding measurement and report trigger condition of A3 incident, then the UE reporting measurement reports if do not satisfy the corresponding measurement and report trigger condition of A3 incident, but has been found the existence of HeNB, the then same reporting measurement reports of UE in the adjacent cell list of UE;
Step 4: source base station sends to target HeNB based on measurement report and is had indication information by interference user;
The target HeNB here is meant the corresponding HeNB of HeNB sign that carries in the measurement report.
There is indication information according to what source base station sent in step 5: target HeNB by interference user, confirms to exist the non-CSG user of the signal interference that receives this HeNB;
Step 6:HeNB triggers power control, reduces the signal transmission power of this HeNB.
Among the foregoing description 3-5, serving BS can comprise the identification information of UE in the information that HeNB sends, after HeNB confirms according to identification information whether this UE is the unauthorized CSG user of this HeNB; If; Then carry out the step of power control, otherwise, the step that power is controlled do not carried out.
Among above-mentioned five embodiment, the non-CSG user that might exist the signal that receives HeNB to disturb judges inaccurate or is disturbed UE instantaneous near situation about leaving behind the HeNB, can cause the process of the frequent adjustment power of HeNB like this.In order to alleviate this problem, can take all factors into consideration and insert request frequency, duration of disturbance, perhaps take all factors into consideration other conditions and wait and determine whether to trigger power control.Concrete processing can be following:
HeNB is provided with a timer sum counter.In time window, whenever receive by interference user existence indication, counter just adds 1.In time window, when counter values reaches certain value, trigger power control, reduce the signal transmission power of this HeNB.Timer time arrives, then counter O reset.
Among above-mentioned five embodiment; When the non-CSG user who gets into HeNB leaves the service range of HeNB gradually; Just require the HeNB can be under the prerequisite that satisfies this non-CSG user performance this moment; Bring to power perhaps reverts to full power gradually, promptly carries out power on reset, so that promote user's under the HeNB performance and speed.The mode that power on reset can adopt macro base station indication HeNB to reset also can adopt the mode of HeNB from master reset.Power on reset specifically can adopt following four kinds of embodiment:
Embodiment one:
The timer control mode is recovered power.
After HeNB triggers power control, start timer and also dispose a time window, in time window, do not trigger power control once more, or the number of times that triggers is less than certain threshold value, then HeNB carries out power on reset.
Embodiment two:
If the power control command that HeNB sends according to macro base station or other HeNB carries out power control, when then HeNB did not receive power control command in time window, HeNB carried out power on reset.This time window is a time window that triggers power control back configuration at HeNB.
Embodiment three:
The Event triggered mode is recovered power.
When the control of the power of HeNB is influenced by Event triggered; Like A3; Incidents such as A4 then when satisfying incident and leave condition, are disturbed the serving BS (macro base station or HeNB) of UE to send the announcement information that Home eNodeB is left at the terminal to target HeNB; Target HeNB carries out power on reset after receiving announcement information.Perhaps; Target HeNB is after receiving announcement information; Whether all users when incident arrives before judging have all satisfied incident is left condition; Promptly whether receive corresponding terminal that the serving BS of whole unauthorized CSG user terminals sends and leave the announcement information of the coverage of Home eNodeB, if then carry out power on reset.
Embodiment four:
According to uplink interference information, suitably adjust power.
HeNB measures the user's of this base station of ownership up IOT, if IOT less than predefined IOT threshold value, then can carry out power on reset, such as the power of suitable lifting HeNB, to promote the speed of its home subscriber.
