Description

A kind of method of definite uplink-downlink configuration, system and equipment

The present patent application be that December 02, application number in 2010 are 201010571151.4 the applying date, denomination of invention divides an application for the patent application of " a kind of method of definite uplink-downlink configuration, system and equipment ".

Technical field

The present invention relates to wireless communication technology field, particularly a kind of method of definite uplink-downlink configuration, system and equipment.

Background technology

Basic duplex mode for the cellular system employing, TDD(Time division duplex, time division duplex) pattern refers to that uplink downlink uses same working band, carry out the transmission of uplink and downlink signals in the different time intervals, have between the up-downgoing protection at interval (Guard Period, GP); FDD(Frequency division duplex; Frequency Division Duplexing (FDD)) pattern refers to that then uplink downlink uses different working bands; can when same, be engraved in the transmission that different frequency carriers carries out uplink and downlink signals, have between the up-downgoing protection bandwidth (Guard Band, GB).

LTE(Long Term Evolution, Long Term Evolution) frame structure of TDD system is more complex slightly, and shown in Figure 1A, a radio frames length is 10ms, comprises special subframe and conventional subframe two classes totally 10 subframes, and each subframe is 1ms.Special subframe is divided into 3 subframes: DwPTS(Downlink Pilot Slot, descending pilot frequency time slot) is used for transmission PSS(Primary Synchronized Signal, master sync signal), PDCCH(Physical Downlink Control Channel, Physical Downlink Control Channel), PHICH(Physical HARQ Indication Channel, the automatic request retransmission indicating channel of physical mixed), PCFICH(Physical Control Format Indication Channel, Physical Control Format Indicator Channel), PDSCH(Physical Downlink Shared Channel, physical down link sharing channel) etc.; GP for the protection between descending and up at interval); UpPTS(Uplink Pilot Slot, uplink pilot time slot) for transmitting SRS (Sounding Reference Signal surveys and uses reference signal), PRACH(Physical Random Access Channel, Physical Random Access Channel) etc.Conventional subframe comprises sub-frame of uplink and descending sub frame, is used for the up/descending control signaling of transmission and business datum etc.Wherein in a radio frames, can dispose two special subframes (being positioned at subframe 1 and 6), also can dispose a special subframe (being positioned at subframe 1).DwPTS subframe in subframe 0 and subframe 5 and the special subframe is always as downlink transfer, and the UpPTS subframe in subframe 2 and the special subframe always is used for uplink, and other subframes can be configured to as uplink or downlink transfer according to needs.

Identical frequency resource is used in the uplink and downlink transmission in the TDD system, transmits uplink/downlink signals in different subframes.In common TDD system, the TD-SCDMA(TD SDMA that comprises 3G) the TD-LTE system of system and 4G, the division of uplink and downlink subframe is static or semi-static, and common way is to determine the division of ascending-descending subframes ratio according to cell type and business proportion roughly and remain unchanged in network planning process.This is comparatively simple way under the background of the big covering of macrocell, and also comparatively effective.And along with technical development, increasing Microcell (Pico cell) Home eNodeB low power base station such as (Home NodeB) is deployed be used to local little covering is provided, in this class residential quarter, number of users is less, and the customer service changes in demand is bigger, so there is situation about dynamically changing in the up-downgoing business proportion demand of residential quarter.

Change in order to adapt to this dynamic business demand ratio, some researchers begin to consider the TDD system is optimized, and introduce more dynamic uplink-downlink configuration scheme, and expectation can adapt to the variation of business proportion, improves system effectiveness.Such as in a TDD network, macrocell adopts the comparatively ratio (DL:UL=3:2) of symmetry of up-downgoing, part femto cell(Femto cell) since the user to download demand more, be configured to down behavior master's ratio (DL:UL=4:1), another part femto cell is more owing to the user uploads demand, is configured to behavior master's ratio (DL:UL=2:3).

If adjacent cell configuration different up-downgoing ratios, cross time-slot then may occur and disturb.In Figure 1B, macrocell is on the time slot that sends downstream signal, and femto cell is used for upward signal and receives, and then occurs between two residential quarters:

Base-station, base-station disturbs, and the femto base station directly receives the downstream signal of Macro base station, will have a strong impact on the femto base station and receive L-UE(Local UE, local UE) quality of upward signal.

Above-mentioned interference will badly influence the performance of whole network, and not have the solution at this interference problem in the prior art.

Embodiment of the invention network equipment determines according to the interference parameter value of Target cell whether Target cell can independently carry out uplink-downlink configuration; Or the base station determines according to the interference parameter value of this residential quarter whether this residential quarter can independently carry out uplink-downlink configuration.Owing to by the interference parameter value of residential quarter, judge whether the residential quarter can independently carry out uplink-downlink configuration, makes dynamic uplink-downlink configuration normally to move, and in dynamic uplink-downlink configuration environment, can reduce the interference between the adjacent area, improve system effectiveness.

Wherein, the embodiment of the invention can be applied to (such as the TD-LTE system) in the TDD system, also can be applied to other needs dynamically to adjust in the system of subframe uplink-downlink configuration, for example TD-SCDMA system and follow-up evolution system thereof, WiMAX(Worldwide Interoperability for Microwave Access, micro-wave access global inter communication) system and follow-up evolution system thereof etc.。

In the declarative procedure below, implement to describe from the cooperation of network side and end side earlier, describe from the enforcement of network side and end side respectively at last, but this does not also mean that the two must cooperate enforcement, in fact, separate when implementing when network side and end side, also solved respectively in network side, the existing problem of end side, when just the two is used in combination, can obtain better technique effect.

Below in conjunction with Figure of description the embodiment of the invention is described in further detail.

As shown in Figure 2, the embodiment of the invention adopts the method for centralized definite uplink-downlink configuration to comprise the following steps:

Step 201, network equipment are determined the interference parameter value of Target cell.

Step 202, network equipment determine according to the interference parameter value of Target cell whether Target cell can independently carry out uplink-downlink configuration.

The embodiment of the invention is centralized to be that centralized management node (being the network equipment of the embodiment of the invention) is set in certain zone, is used for the interference level between the judgement neighbor cell.The geographical position of each residential quarter of known its administration of this centralized management node and neighbouring relations each other, and the type of each base station, information such as transmitting power.The interference parameter value of each neighbor cell that the base station will measure sends to the centralized management node by network interface, this node place interference strength threshold value that prestores, by if measurement result between the neighbor cell is disposed different uplink-downlink configuration with comparing to determine between two neighbor cells of interference threshold value, whether can cause unacceptable intersection to be disturbed.

In the step 202, network equipment compares interference parameter value and Target cell corresponding threshold, determines according to comparative result whether Target cell can independently carry out uplink-downlink configuration.

Wherein, the interference parameter value includes but not limited to one or more in the following parameters value:

RSRP(Reference signal received power, Reference Signal Received Power) value, RIP(Received Interference Power, the interference received power) value, CQI(Channel Quality Indicator, the channel quality indication) value and RSRQ(Reference Signal Received Quality, Reference Signal Received Quality) value.

Describe respectively below.

Situation one, interference parameter value comprise the RSRP value, and the RSRP value here is the RSRP value that Target cell receives adjacent cell reference signals.

Wherein, network equipment can compare the RSRP value first threshold corresponding with Target cell, judge that a RSRP value is whether less than the first threshold of correspondence, if, determine that then Target cell can independently carry out uplink-downlink configuration, otherwise determine that Target cell can not independently carry out uplink-downlink configuration.

Shown in Figure 1B, be neighbouring relations between the known Macro cell of network equipment and the femto cell, Macro cell reports and detects the RSRP intensity that receives Femto cell reference signal is X dBm.It is M dBm (this thresholding records by emulation assessment or network implementation) that network equipment has been preset the admissible interference level value of Macro cell, if X＜M determines that then Macro cell can independently carry out uplink-downlink configuration.

Here the first threshold of residential quarter correspondence can be stipulated in agreement in advance.Can also upgrade first threshold as required.

In the step 201, the RSRP value that network equipment is determined is the base station measurement under the Target cell and reports.

In force, the base station is measured the adjacent cell reference signals of receiving in measuring at interval or by sub-frame of uplink, obtains a RSRP value.

Concrete, if the base station is measured the adjacent cell reference signals of receiving in measuring at interval, obtain a RSRP value, then base station allocating and measuring interval (eNB measurement gap) be can be, one section time that is used for base station measurement, for example 1ms or 5ms are defined as.In interval time of measurement, the base station transmit signals intensity of base station measurement neighbor cell, for example measure R SRP value.Go out neighbor cell if the base station is unidentified before measuring, then neighboring cell search and synchronous work need be finished in the base station in this measurements at interval, therefore need the long measurement interval of configuration, for example 5ms or more than; If the base station had searched adjacent residential quarter before measuring, then can dispose short measurement at interval, for example below the 5ms.In measuring at interval, the base station is not carried out any local area signal and is sent and receive.Be higher than predefined threshold value if measure the RSRP value that Target cell receives a certain adjacent area, if it is different with local area up-downgoing proportioning then to identify this neighbour residential quarter, the transmitting of this neighbour residential quarter will be caused the up reception of local area and be intersected interference.

If the base station by sub-frame of uplink, is measured the adjacent cell reference signals of receiving, obtain a RSRP value, then neighbor base station transmit measurement, for example measure R SRP value are carried out at sub-frame of uplink in the base station.This scheme does not need the measurement interval of configure dedicated, and the uplink scheduling that the sub-frame of uplink that the base station is measured at needs stops this community user gets final product.Because available continuous sub-frame of uplink is less, be higher than predefined threshold value if measure the RSRP value that Target cell receives a certain adjacent area, if it is different with local area up-downgoing proportioning then to identify this neighbour residential quarter, transmitting of this neighbour residential quarter will cause intersection to disturb the up reception of local area.

Preferable, also comprise before the step 202:

Network equipment is determined the 2nd RSRP value of the adjacent residential quarter receiving target cell reference signals of Target cell; Accordingly, in the step 202, network equipment determines according to a RSRP value and the 2nd RSRP value whether Target cell can independently carry out uplink-downlink configuration.

Concrete, network equipment compares the RSRP value first threshold corresponding with Target cell, and the first threshold that the 2nd RSRP value is corresponding with adjacent residential quarter compares, whether the RSRP value of judging two residential quarters is all less than the first threshold of correspondence, if, then uplink-downlink configuration can independently be carried out in definite first residential quarter, otherwise determines that Target cell can not independently carry out uplink-downlink configuration.If can also determine that simultaneously adjacent residential quarter can independently carry out uplink-downlink configuration, otherwise determine that adjacent residential quarter can not independently carry out uplink-downlink configuration.

Shown in Figure 1B, each base station reports detected adjacent base station RSRP information, be neighbouring relations between the known Macro cell of network equipment and the femto cell, and know that Macro cell transmitting power is 46dBm, femto cell transmitting power is 20dBm, it is X dBm that Macro cell reports detected Femto cell RSRP intensity, and it is Y dBm that femto cell reports the RSRP intensity that detects Macro cell.It is M dBm that network equipment has been preset the admissible interference level value of Macro cell, and the admissible interference level value of femto cell is N dBm.After network equipment obtains metrical information, when X＜M and Y＜N, concentrate between judgement two residential quarters and can dispose different uplink-downlink configuration.

Wherein, network equipment determines that the mode of the 2nd RSRP value has two kinds:

Base station under mode one, the adjacent residential quarter reports the 2nd RSRP value; Accordingly, network equipment receives the affiliated base station measurement in adjacent residential quarter and the 2nd RSRP value that reports.

The affiliated base station of the mode that the 2nd RSRP value is determined in base station under the adjacent residential quarter and Target cell determines that the mode of a RSRP value is identical, does not repeat them here.

The Target cell that mode two, network equipment reception base station report and the Pathloss value between the adjacent residential quarter, according to the transmission power level of Target cell, and the Pathloss value between Target cell and the adjacent residential quarter, determine the 2nd RSRP value.

Concrete, the base station under the Target cell reports the Pathloss value between Target cell and the adjacent residential quarter; Network equipment is after the Pathloss value of receiving between Target cell and the adjacent residential quarter, and it is poor that the transmission power level of Target cell and Pathloss value are done, and the value that obtains is as the 2nd RSRP value.

In force, the ascending-descending subframes assignment information of neighbor cell and the CRS of neighbor cell (Cell-specific Reference Signal are known by network interface in the base station, cell specific reference signal) transmission power information (such as Macro cell or Pico cell, can be known as above information by X2 interface; Femto cell can be known as above information by the S1 interface), subtract each other with the CRS transmission power information of corresponding neighbor cell according to a RSRP base station then, obtains the Pathloss value between this residential quarter and the neighbor cell.

Concrete employing mode one still is that mode two can be set in agreement, also can be notified by high level.

Situation two, interference parameter value comprise the RIP value.

Wherein, network equipment can second threshold value that the RIP value is corresponding with Target cell compare, and judges the RIP value whether less than second threshold value of correspondence, if, determine that then Target cell can independently carry out uplink-downlink configuration, otherwise determine that Target cell can not independently carry out uplink-downlink configuration.

Here second threshold value of residential quarter correspondence can be stipulated in agreement in advance.Can also upgrade second threshold value as required.

In the step 201, the RIP value that network equipment is determined is the base station measurement under the Target cell and reports.

In force, the base station is measured all interference except this residential quarter useful signal of receiving by sub-frame of uplink, obtains the RIP value.

Concrete, the RIP value that the base station receives in the sub-frame of uplink measurement, this RIP value comprises thermal noise etc. for removing all interference values outside the local area useful signal.

Situation three, interference parameter value comprise CQI value and/or RSRQ value, here CQI value and/or RSRQ value comprise three kinds: include only the CQI value, include only the RSRQ value, comprise CQI value and RSRQ value.

Wherein, if the interference parameter value comprises the CQI value, network equipment can the 3rd threshold value that the CQI value is corresponding with Target cell compare, judge that the CQI value is whether less than the 3rd threshold value of correspondence, if, determine that then Target cell can independently carry out uplink-downlink configuration, otherwise determine that Target cell can not independently carry out uplink-downlink configuration.

If the interference parameter value comprises the RSRQ value, network equipment can the 4th threshold value that the RSRQ value is corresponding with Target cell compare, judge that the RSRQ value is whether less than the 4th threshold value of correspondence, if, determine that then Target cell can independently carry out uplink-downlink configuration, otherwise determine that Target cell can not independently carry out uplink-downlink configuration.

If the interference parameter value comprises CQI value and RSRQ value, network equipment can the 3rd threshold value that the CQI value is corresponding with Target cell compare, the 4th threshold value that the RSRQ value is corresponding with Target cell compares, judge the CQI value whether less than the 3rd threshold value of correspondence and RSRQ value whether less than the 4th threshold value of correspondence, if, determine that then Target cell can independently carry out uplink-downlink configuration, otherwise determine that Target cell can not independently carry out uplink-downlink configuration.

Here the 3rd threshold value of residential quarter correspondence and the 4th threshold value can be stipulated in agreement in advance.Can also upgrade the 3rd threshold value and the 4th threshold value as required.

In the step 201, the CQI value that network equipment is determined and/or RSRQ value are that the base station under the Target cell reports.

In force, the base station receives CQI value and/or the RSRQ value that reports from UE, and CQI value and/or the RSRQ value of receiving reported the network measurement equipment.

Concrete, in order to identify the annoyance level of the UE of UE, cell base station is collected cycle or the aperiodic broadband CQI feedback information that local area UE reports, and/or (can trigger UE such as the base station reports to collect RSRQ information that local area UE reports etc.; A time also can be set allows the UE periodic report).If the broadband CQI value that reports of UE is lower than predefined thresholding, perhaps the RSRQ value that reports of UE is lower than predefined thresholding, and then local area UE may receive the intersection interference of adjacent area UE.In order to make result of determination more accurate, can handle measurement result, for example whether the measurement result of smooth mode service time in statistics a period of time is lower than desired value, perhaps for example adds up a plurality of users' measurement result and judges.

Part in as required can operating position one～situation three also can be used all.No matter be part or whole, as long as each interference parameter value satisfies the condition that Target cell can independently carry out uplink-downlink configuration, just determine that Target cell can independently carry out uplink-downlink configuration.

Also comprise after the step 202:

After definite Target cell can independently carry out uplink-downlink configuration, uplink-downlink configuration was independently carried out in network equipment notification target residential quarter, further can also notify each residential quarter adjacent with Target cell;

After definite Target cell can not independently carry out uplink-downlink configuration, network equipment further can also be notified each residential quarter adjacent with Target cell with unified uplink-downlink configuration information notification target residential quarter.

The base station is set uplink-downlink configuration according to the notice of network equipment, and sets up this residential quarter, and beginning provides communication service to UE.
