Abstract
The invention provides a method for reducing same frequency interference, which comprises the following steps of: selecting a high speed packet access (HSPA) carrier and a high speed downlink packet access (HSDPA) carrier for user equipment (UE) according to the position of the UE in a UE access process, and dynamically adjusting the carrier type of the UE according to the interference level in a process for providing service for the UE so that the marginal region of a cell uses the HSDPA carrier and the central region of the cell uses the HSPA carrier. The method can effectively reduce the same frequency interference of the marginal region of the cell by regionally configuring the HSPA carrier and the HSDPA carrier.
Description
Technical field
The present invention relates to the interference control technology in the mobile communication system, particularly relate to the method that reduces co-channel interference in the TD-SCDMA system.
Background technology
The TD-SCDMA data network has become the important application form of TD-SCDMA at present, simple high speed downlink packet inserts the descending impression that (HSDPA) carrier networking can promote unique user, but along with increasing of number of users, the simple HSDPA carrier networking that uses provides the drawback of data, services to manifest gradually, it is seriously limited mainly to show as ascending resource, if be that subscriber equipment (UE) distributes up 64K business, then every carrier wave maximum UE number that can carry is 3, if for UE distributes the 32K business to improve the UE number that can carry, then can make serious decline of service quality (QoS) of a lot of UE.
Insert the rapid maturation of the terminal technology of (HSUPA) along with high speed uplink packet, commercial high-speed packet inserts (HSPA) carrier wave (namely supporting the carrier wave of HSUPA and HSDPA simultaneously) in the TD-SCDMA system becomes and solves the resource-constrained effective means of TD-SCDMA uplink code channel, so the inevitable HSPA carrier wave (being called the HSPA carrier wave) of only supporting the carrier wave (being called the HSDPA carrier wave) of HSDPA and supporting HSUPA and HSDPA simultaneously that exists simultaneously in the following TD-SCDMA system.
In the HSUPA technology, because the up modulation system that can use 16QAM of terminal, this requires transmitting power far above common DPCH (DPCH) channel, especially when being in cell edge, UE needs bigger transmitting power, like this, will inevitably cause the UE on the HSPA carrier wave that the UE on the HSDPA carrier wave of adjacent residential quarter is on every side produced bigger co-channel interference, therefore can have the serious disturbance problem.Therefore, how carrying out uplink interference control in the HSPA of TD-SCDMA system networking process is the problem that must solve.
For disturbing control problem in the HSUPA network, it generally is the control mode that adopts the recruitment (RoT) of base station receiver input thermal noise, under this control mode, the base station is according to the annoyance level in the RoT back noise judgement current area of its measurement, and when interference is higher, control by part UE being carried out power, realize the control to disturbing in the residential quarter.In WCDMA, allow this residential quarter to carry out power control to the adjacent residential quarter UE that is in its cell edge, like this, the base station can be by all cause that the UE of interference carries out power control in the residential quarter, therefore can effectively realize the control to co-channel interference, thereby make that the interference control level of RoT is higher in WCDMA.But in the TD-SCDMA system, do not allow this residential quarter to carry out power control to being in other adjacent residential quarter UE of its cell edge, like this, adopt the control mode of ROT only can carry out power control to the UE in this residential quarter in the TD-SCDMA system, and can't carry out power control to causing the higher adjacent residential quarter UE of this area interference level, therefore, in the TD-SCDMA system, merely use the RoT control strategy not control the co-channel interference of cell edge region effectively.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method that reduces co-channel interference, and this method can control effectively to the co-channel interference in the TD-SCDMA system.

When existence in the system need provide the UE of service, the measurement mechanism that the RNC basis is preset was in the measurement of each initiation measuring period to the uplink interference signal code power (ISCP) of each HSPA carrier wave and each HSDPA carrier wave;
When the ISCP of described HSDPA carrier wave measurement result triggers gravity treatment ISCP thresholding greater than default HSDPA carrier wave, described RNC triggers the current service cell of UE on this HSDPA carrier wave and the PCCPCH RSCP of adjacent residential quarter measures, when the difference of the PCCPCH of this Serving cell and adjacent residential quarter RSCP measurement result during greater than default HSDPA carrier wave gravity treatment RSCP thresholding, described RNC triggers described UE and migrates to the HSPA carrier wave;
When the ISCP of described HSPA carrier wave measurement result triggers gravity treatment ISCP thresholding greater than default HSPA carrier wave, described RNC triggers the current service cell of UE on this HSPA carrier wave and the PCCPCH RSCP of adjacent residential quarter measures, when the difference of the PCCPCH of this Serving cell and adjacent residential quarter RSCP measurement result during less than default HSPA carrier wave gravity treatment RSCP thresholding, described RNC triggers described UE and migrates to the HSDPA carrier wave.
Preferably, when inserting with the UE request, the access carrier type of determining described UE is HSDPA carrier wave or HSPA carrier wave, comprising:
Judge that whether the measured value of described PCCPCH received signal code power (RSCP) is greater than default initial access carrier type selecting thresholding, if, the access carrier type of then determining described UE is the HSPA carrier wave, otherwise determines that the access carrier type of described UE is the HSDPA carrier wave.
In sum, the method of the reduction co-channel interference that the present invention proposes, in the UE access procedure, be the selection that UE carries out HSPA carrier wave and HSDPA carrier wave according to the UE position, and in the process that service is provided for UE, according to interference level the carrier type of UE is dynamically adjusted, thereby by the use zone of HSPA carrier wave and HSDPA carrier wave is rationally divided, realized the control to the cell border areas co-channel interference.
Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with specific embodiment.
Core concept of the present invention is: by the HSUPA in the residential quarter and DPCH channel are rationally prepared, reduce the co-channel interference that this residential quarter produces the adjacent area.Type of service (being HSDPA carrier wave or HSPA carrier wave) according to carrier wave is divided into two parts with the residential quarter, a part is the zone nearer apart from the base station, be called the central area, another part is other zones except the central area, be called fringe region, the UE that will be in cell edge region is distributed on the HSDPA carrier wave, the UE that will be in the center of housing estate zone is distributed on the HSPA carrier wave, like this, use the UE of HSUPA channel will concentrate on the center of housing estate zone, use the UE of DPCH channel then can concentrate on cell edge region, so, on the one hand, because the UE on the HSDPA carrier wave and the UE on the HSPA carrier wave (namely using the UE of HSUPA channel) branch in the zones of different of residential quarter, therefore can largely reduce the co-channel interference of the UE on the HSDPA carrier wave of the UE on the HSPA carrier wave in the residential quarter; On the other hand, because the UE branch on the HSPA carrier wave in the central area of residential quarter, therefore, can not produce co-channel interference to the UE on the cell edge region because of the big transmitting power of up HSUPA channel.Based on this, the present invention will be by being that UE distributes HSDPA carrier wave or HSPA carrier wave according to the UE position when UE inserts, namely when UE is near apart from center of housing estate, distribute the HSPA carrier wave for it, when UE is far away apart from center of housing estate, distribute the HSDPA carrier wave for it, and when service is provided for UE, dynamically the employed carrier type of UE is adjusted according to current interference level, with the co-channel interference in the reduction system.
The method of the reduction co-channel interference that the embodiment of the invention one proposes mainly may further comprise the steps:
Step 101, when RNC receives the access request of UE, the measured value of the PCCPCH RSCP of its current service cell that RNC reports according to described UE, the access carrier type of determining described UE is HSDPA carrier wave or HSPA carrier wave.
In actual applications, there is relation the residing position of the size of RSCP and UE, its measured RSCP value is more big when UE is more near apart from the base station, when UE is more far away apart from the base station, its measured RSCP value is more little, therefore, the PCCPCH RSCP value that reports according to UE among the present invention, access carrier type to UE is determined, when PCCPCH RSCP value is big, determine to distribute the HSDPA carrier wave, hour determine to distribute a HSPA carrier wave when the PCCPCHRSCP value, can guarantee that like this UE that will be in cell edge when UE inserts is distributed on the HSDPA carrier wave, the UE that will be in center of housing estate is distributed on the HSPA carrier wave.Here, determine UE the access carrier type concrete grammar can for:
Judge that whether the measured value of described PCCPCH RSCP is greater than default initial access carrier type selecting thresholding RACH_HSPA_TH (RACH_HSPA_TH＞0), if, the access carrier type of then determining described UE is the HSPA carrier wave, otherwise determines that the access carrier type of described UE is the HSDPA carrier wave.
Here, the present invention utilizes this initial access carrier type selecting thresholding RACH_HSPA_TH to limit the zone of use HSPA carrier wave in the residential quarter and the zone of using the HSDPA carrier wave, because UE is more little apart from the PCCPCH RSCP of base station its survey more far away, therefore, when this RACH_HSPA_TH arrange more big, use the zone of HSPA carrier wave more little in the residential quarter, correspondingly, use the zone of HSDPA carrier wave more big, otherwise, when this RACH_HSPA_TH arrange more little, the zone of use HSPA carrier wave is more big the residential quarter in, correspondingly, use the zone of HSDPA carrier wave more little.And UE quantity has relation in the degree of disturbing between UE in a certain zone and this zone, and when UE was too much, its interference will inevitably be big.Therefore, in the practical application, those skilled in the art can rationally arrange this RACH_HSPA_TH according to factors such as the quantity of UE in the concrete applied environment, the characteristic distributions of UE, receivable target interference values.
Step 102, when existing in the system when UE of service need be provided, RNC initiates measurement to the up ISCP of each HSPA carrier wave and each HSDPA carrier wave according to default measurement mechanism in each measuring period; When the ISCP of described HSDPA carrier wave measurement result triggers gravity treatment ISCP thresholding greater than default HSDPA carrier wave, described RNC triggers the current service cell of UE on this HSDPA carrier wave and the PCCPCH RSCP of adjacent residential quarter measures, when the difference of the PCCPCH of this Serving cell and adjacent residential quarter RSCP measurement result during greater than default HSDPA carrier wave gravity treatment RSCP thresholding, described RNC triggers described UE and migrates to the HSPA carrier wave; When the ISCP of described HSPA carrier wave measurement result triggers gravity treatment ISCP thresholding greater than default HSPA carrier wave, described RNC triggers the current service cell of UE on this HSPA carrier wave and the PCCPCH RSCP of adjacent residential quarter measures, when the difference of the PCCPCH of this Serving cell and adjacent residential quarter RSCP measurement result during less than default HSPA carrier wave gravity treatment RSCP thresholding, described RNC triggers described UE and migrates to the HSDPA carrier wave.
Above-mentioned steps is used for realizing according to current interference level the employed carrier type of UE dynamically being adjusted when system's existence need provide the UE of service.To realize the real-time control to interference level in the residential quarter.
In the above-mentioned steps, by the periodic measurement of up ISCP being realized the monitoring to interference level in the residential quarter, described measurement mechanism, namely be used for triggering and can adopt the trigger mechanism realization of existing measurement event to the mechanism of the up ISCP measurement of each HSPA carrier wave and each HSDPA carrier wave, for example can be affair, also can be periodic measurement, concrete which kind of mode that adopts can be selected according to actual needs by those skilled in the art, as long as can reach the real-time monitoring to interference level in the residential quarter, not repeat them here.
In the above-mentioned steps, when the ISCP of HSDPA carrier wave measurement result triggers gravity treatment ISCP thresholding ISCP_HSDPA_TH greater than default HSDPA carrier wave, illustrate that the interference that the UE on this HSDPA carrier wave is subjected to has exceeded the receptible level of system, the main cause that this situation occurs may be current use HSDPA carrier wave UE quantity too much due to.Can be to utilize its Serving cell of the current measurement of UE and the PCCPCH RSCP difference of adjacent residential quarter that the UE that needs move is determined in the present embodiment by (namely less UE being disturbed in the adjacent area) nearer apart from the base station moved on the HSPA carrier wave and reduce interference in these cases.Concrete grammar is: trigger the ISCP measurement result and greater than the UE on the HSDPA carrier wave of ISCP_HSDPA_TH the PCCPCH RSCP of its current service cell and adjacent residential quarter is measured, UE is in the process of measuring, to calculate the difference of the PCCPCH RSCP of the PCCPCH RSCP of Serving cell and adjacent residential quarter, and this difference reported RNC, RNC will judge that whether this difference is greater than HSDPA carrier wave gravity treatment RSCP thresholding RSCP_HSDPA_TH, if greater than would illustrate that this UE is nearer apart from the base station of its Serving cell, the adjacent residential quarter of distance is far away relatively, and the interference to adjacent residential quarter is less relatively, the interference level to adjacent residential quarter influences and can ignore on the HSPA carrier wave if move to it this moment, and owing to reduced the UE quantity of distributing the HSDPA carrier wave in the residential quarter, therefore, the co-channel interference of other HSDPA carrier waves of cell edge region also can reduce.
In the above-mentioned steps, when the ISCP of HSPA carrier wave measurement result triggers gravity treatment ISCP thresholding ISCP_HSPA_TH greater than default HSPA carrier wave, illustrate that the interference that the UE on this HSDPA carrier wave is subjected to has exceeded the receptible level of system, the main cause that this situation occurs may be: use the UE of HSPA carrier wave to move to cell edge region from the center of housing estate zone, but still use the HSPA carrier wave, like this, can be subjected to the interference of cell edge region UE.In these cases can be by this UE be moved on the HSDPA carrier wave, be this UE and reconfigure the HSDPA carrier wave, because in the carrier wave reconfiguration course, can select to be adjacent the carrier resource of UE alien frequencies, therefore can reduce the interference that this UE is subjected to by the process that this carrier wave is reshuffled.Be to utilize its Serving cell of the current measurement of UE and the PCCPCH RSCP difference of adjacent residential quarter that the migration whether this UE needs to carry out carrier wave is judged in the present embodiment.Concrete grammar is: trigger the ISCP measurement result and greater than the UE on the HSPA carrier wave of ISCP_HSPA_TH the PCCPCH RSCP of its current service cell and adjacent residential quarter is measured, UE is in the process of measuring, to calculate the difference of the PCCPCH RSCP of the PCCPCH RSCP of Serving cell and adjacent residential quarter, and this difference reported RNC, RNC will judge that whether this difference is less than HSPA carrier wave gravity treatment RSCP thresholding RSCP_HSPA_TH, if less than would illustrate that this UE far namely is in the fringe region of residential quarter apart from the base station of its Serving cell, because the transmitting power of up DPCH is less than the transmitting power of HSUPA, therefore, this moment it being moved to the co-channel interference that on the HSDPA carrier wave UE (comprising this residential quarter UE and adjacent residential quarter UE) that is in cell edge region is produced can obviously reduce.
Here need to prove, all related in this step threshold values are all more than or equal to zero, wherein, system is more high to the requirement of interference level, it is more little that described ISCP_HSPA_TH and ISCP_HSDPA_TH need arrange, it is more big that described RSCP_HSDPA_TH arranges, when needing migration the position at described UE place from center of housing estate more close to, the UE that can move can be more few, and that described RSCP_HSPA_TH arranges is more little, when needing migration the position at described UE place from center of housing estate more away from, the UE that can move can be more few, the occurrence of above-mentioned thresholding can be arranged according to actual needs by those skilled in the art, does not repeat them here.
In the such scheme, the difference of the PCCPCH RSCP of described Serving cell to UE and the PCCPCH RSCP of adjacent residential quarter is calculated and can be realized at the RNC place, that is to say, UE only need report RNC with the measurement result of the PCCPCH RSCP of the PCCPCH RSCP of Serving cell and adjacent residential quarter and get final product, and by RNC this difference is calculated.Which kind of mode RNC specifically adopts obtain above-mentioned difference, can be selected according to actual needs by those skilled in the art.
Pass through technique scheme, the present invention is the selection that UE carries out HSPA carrier wave and HSDPA carrier wave according to the UE position in the UE access procedure, and in the process that service is provided for UE, according to interference level the carrier type of UE is dynamically adjusted, like this, realized according to area configurations HSPA carrier wave and HSDPA carrier wave, be that fringe region uses the HSDPA carrier wave, the HSPA carrier wave is used in the central area, like this, on the one hand, to being in the UE of cell edge region, can utilize the rapid power control of up DPCH channel and less uplink transmission power thereof to realize effective control to the fringe region co-channel interference, on the other hand for the UE that is in center of housing estate, then can take full advantage of its uplink ability, it is distributed on the HSPA carrier wave, makes that the whole up throughput ratio in residential quarter is higher, also avoided it that adjacent residential quarter is produced co-channel interference simultaneously.
In sum, more than be preferred embodiment of the present invention only, be not for limiting protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
