In actual applications, may be varied for entity that small-cell is managed, as management entity independently, be controlled by the device of base station etc.The described device that is controlled by base station may be the smart antenna of remote radio head (Remote Radio Head, RRH), base station etc.Regardless of implementation, the entity that small-cell is managed can be referred to as to small-cell management entity.Following base station triggers small-cell management entity receives and receives corresponding to base station triggers small-cell.
In base station side, base station can be triggered subordinate small-cell management entity and be received the upstream data that UE sends, and receive the quality of the described upstream data that small-cell management entity reports, according to described quality, be defined as again the small-cell of UE configuration, the small-cell information of the small-cell for UE configuration can also be notified to UE and corresponding small-cell management entity.
Described UE has conventionally set up Radio Resource control (RRC) with base station and has been connected, and can carry out data interaction with base station.
Described small-cell management entity can receive the upstream data that UE sends, and small-cell management entity normally closes before by base station triggers, or is held open for other UE.
The upstream data that described UE sends, is the upstream data that UE sends to base station, or UE is by the upstream data of the up-link carrier transmission of the macrocell with base station control.Described upstream data can comprise: the control signal or uplink reference signals or the user data that by physical uplink control channel (PUCCH) or Physical Uplink Shared Channel (PUSCH), send.Described upstream data can be also the data of making an appointment.
When base station triggers subordinate small-cell management entity receives the upstream data of UE transmission, base station can notify described small-cell management entity for receiving UE, to send the relevant information of upstream data, makes described small-cell management entity can accurately receive and resolve the upstream data that described UE sends.The relevant information of described upstream data comprises one or more in following content: the resource information of upstream data, coded message, carrier frequency point information, upstream data type, UE sign (referring to the sign of the corresponding UE of data that small-cell management entity receives).
In order to guarantee that base station can receive the quality of the described upstream data that small-cell management entity reports, small-cell management entity can carry out according to stipulated form the assessment of channel quality to the UE upstream data receiving, and by assessment result reporting base station.If channel quality does not meet the demands, small-cell management entity can not report assessment result to base station so.
The appraisal procedure of channel quality has multiple, as: small-cell management entity is determined channel quality by judging whether the upstream data can correct demodulation receiving, or the received power of the upstream data that receives by calculating of small-cell management entity is determined channel quality.
In order to make base station can be defined as the small-cell of UE configuration, base station, when receiving the UE upstream data of subordinate small-cell management entity forwarding, can be assessed upstream data, and according to assessment result, is defined as the small-cell of UE configuration; Or the channel quality of the upstream data that base station can report according to small-cell management entity, is defined as the small-cell that UE configures.Afterwards, base station can send small-cell configuration signal to small-cell management entity, take and notifies this small-cell management entity as UE configures corresponding small-cell.For the small-cell management entity that there is no reporting channel quality, base station can think that small-cell corresponding to these small-cell management entities is that the improper UE of being configures.
When small-cell management entity does not receive the signaling (as: small-cell configuration signal) for UE configuration of base station transmission, the small-cell of small-cell management entity confirmation self correspondence can not configure for UE.In addition, after small-cell management entity determines that the small-cell of self correspondence can be for UE configuration, small-cell management entity can send measuring-signal.Have, after small-cell management entity determines that the small-cell of self correspondence can be for UE configuration, base station can send small-cell to this small-cell management entity and activate signaling again.
In order to make base station can trigger subordinate small-cell management entity, base station can, by the descending carrier of X2 mouth or base station, send and trigger signaling to small-cell management entity.
Notice small-cell, base station management entity is that the signaling that UE is configured comprises: UE sign, small-cell sign (optionally).

When small-cell management entity calculates the channel quality of the upstream data receive or power, can adopt compensating factor to calibrate the channel quality calculating or power.Wherein compensating factor can be fixed value, and this value can obtain by emulation or empirical value.
In UE side, UE can set up RRC with the macrocell that base station is controlled and be connected, and sends upstream data by the up-link carrier of macrocell; Can also receive base station by the signaling of the configuration small-cell of the descending carrier transmission of macrocell.
Described upstream data can be that UE is at the upstream data that receives the agreement sending after the triggering signaling of base station.
UE can also be received as the measuring-signal that the small-cell management entity of small-cell of self configuration sends, and to base station feedback measurement result.Base station can be defined as the small-cell that UE activates according to the measurement result of receiving.Wherein, activation is that when UE receives after the activation command of corresponding small-cell, so corresponding small-cell just can provide for UE the transmission service of business datum for what be configured to the small-cell of UE.Small-cell configures to after UE, does not represent that small-cell is just UE service data transmission, just can provide business data transmission after only having activation.
UE can also receive the signaling of the activation small-cell management entity of base station transmission, and the small-cell management entity of activation can provide service for UE.
Particularly, after introducing small-cell, (the particularly small-cell of new carrier type), because newly the small-cell of carrier type does not need to support UE resident, therefore can be applied to the present invention by this characteristic.While not specifying below, small-cell refers to the small-cell of new carrier type.Certainly, the present invention is also applicable to conventional small-cell, because conventional small-cell also can accomplish not support that UE is resident by prior art.In addition, the present invention is also applicable to the small-cell of supporting that UE is resident, just can produce certain influence for capacity, the mobility of system.
With reference to figure 1 and Fig. 2, the downlink carrier frequency of base station is f1, and uplink carrier frequency is f3; The uplink carrier frequency of small-cell management entity is f4, and downlink carrier frequency is f2.In macrocell under base station is controlled and its subordinate's the overlapping covering in small-cell, while there is no the UE of connection status in small-cell, the small-cell management entity of small-cell keeps closing (like this can be energy-conservation), and the UE in small-cell resides in corresponding macrocell.When base station determines that need to configure small-cell with transmission data for UE time, base station triggers subordinate small-cell management entity receives the upstream data that UE sends in the uplink carrier frequency of base station.In order to allow small-cell management entity can receive the upstream data of UE, base station need to send UE the relevant information of upstream data and notify to small-cell management entity, makes small-cell management entity can in the uplink carrier frequency of base station, receive exactly the upstream data that UE sends.Subordinate small-cell, base station management entity receives after the upstream data of UE transmission, can process the upstream data receiving, and result is sent to base station, and base station can be defined as according to described result the small-cell of UE configuration.
In addition, corresponding small-cell management entity can will be notified for the small-cell of UE configuration in base station, and notice is to UE.The small-cell management entity that base station can also be triggered as the small-cell of UE configuration sends measuring-signal at downlink carrier frequency, UE carries out and measures the small-cell of configuration, by measurement result reporting base station, base station is defined as according to the measurement result of receiving the small-cell that UE activates.
When base station triggers subordinate small-cell management entity receives the upstream data of UE transmission, the macrocell that UE has controlled with base station has conventionally been set up RRC and has been connected, and the carrier wave by macrocell with base station communication, UE is sending upstream data in this case.For setting up with base station the UE that RRC is connected, base station can send signaling and trigger UE transmission upstream data so.
When base station triggers subordinate small-cell management entity receives UE transmission upstream data, small-cell management entity keeps closed condition, so that energy-conservation.Certainly, small-cell management entity may be also other UE services, and at this moment small-cell management entity receives after described triggering signaling, and small-cell management entity receives the upstream data that described UE sends.Described upstream data can be to send by carrier wave corresponding to macrocell, can be also to send by carrier wave corresponding to small-cell.Described upstream data can send to base station, can be also to send to specially small-cell management entity.The upstream data that UE sends comprises control signal or uplink reference signals or the user data sending by PUCCH or PUSCH.
It is following one or more for receiving the relevant information of UE upstream data that described small-cell management entity is notified in base station: the carrier frequency point information that the coded message that the resource information of upstream data, upstream data adopt, upstream data send, upstream data type, UE sign.These information can be combined with, and what wherein upstream data type referred to UE transmission is reference signal or user data.When upstream data is user data, base station need to be transmitted to subordinate small-cell management entity by the uplink authorization information sending for UE, small-cell management entity has just been known the control information that upstream data is corresponding like this, also needs in addition to notify the information such as upstream data frequency, UE sign.When upstream data is reference signal, can send reference signal by the mode of prior agreement, thereby make small-cell management entity to receive upstream data according to the mode of prior agreement.
The processing of the upstream data that small-cell management entity sends for the UE receiving can be divided into several situations below: the first situation, small-cell management entity is transmitted to base station by the upstream data receiving, demodulation or judgement channel quality are carried out to the upstream data forwarding in base station, if correctly demodulation or channel quality meet the demands, just think that this small-cell can configure for UE.The second situation, the algorithm that between small-cell management entity and base station, agreement is used upstream data to calculate channel quality (for example can adopt the method for calculating channel quality indication (CQI), or calculate the power of the upstream data receiving), by small-cell management entity, according to the mode of agreement, utilized the upstream data assessment channel quality of the UE of reception, and assessment result is sent to base station.Base station is UE configuration small-cell according to the assessment result of receiving.The third situation, the upstream data that small-cell management entity demodulation receives, correctly whether by, solution transfers to judge channel quality, if correct demodulation, channel quality meets the demands, and by assessment result reporting base station; If correctly demodulation, thinks that channel quality can not meet the demands, can not report assessment result to base station.If base station does not receive the assessment result of the upstream data that subordinate small-cell management entity reports, so just think that small-cell corresponding to this small-cell management entity can not configure for UE.
After above-mentioned processing, base station has obtained the assessment result of UE upstream data, can be according to this assessment result or for example, in conjunction with other information (load information of small-cell), judges whether the small-cell that this small-cell management entity is corresponding is suitable for UE configuration again in base station, and the most at last for the information notice UE of the small-cell of UE configuration, notify corresponding small-cell management entity for UE configures simultaneously.If small-cell management entity has reported the UE upstream data receiving to base station, and whether base station is not the signaling of UE configuration small-cell to small-cell management entity feedback, small-cell management entity thinks that self is not for UE is configured so.If small-cell management entity has received the signaling for UE configuration small-cell that base station sends, small-cell management entity can send measuring-signal so.
After UE knows that base station is the small-cell self configuring, just can start to receive the measuring-signal that the small-cell management entity of these small-cells sends, be used for carrying out and measure, and measurement result is reported to base station, base station is defined as according to measurement result (or again in conjunction with small-cell loading condition) small-cell that UE activates, and to notify the small-cell management entity of this small-cell be that UE activates.
Base station triggers small-cell management entity receives the signaling of UE upstream data can pass through X2 mouth, or the descending carrier of base station sends to corresponding small-cell management entity.
Small-cell management entity reports the signaling for the channel quality assessment of UE upstream data, comprises that subordinate is one or more: carry one or more UE signs (comprise C-RNTI, receive the resource location of upstream data, UEID, the configuration information of upstream data); Small-cell sign is (if adopt and eat dishes without rice or wine between small-cell management entity and base station, sign comprises small-cell index, small-cell ID, small-cell virtual ID, positional information), for the assessment result (comprise and judge whether correct demodulation, RSRP, channel measurement quality) that receives data.
Notice small-cell, base station management entity comprises for the signaling (as small-cell configuration signal) of which UE configuration: UE sign, small-cell sign is (optional, if only notify a small-cell management entity, just do not use this parameter, if a plurality of small-cells management entity is notified simultaneously, use this parameter).
The signaling of the small-cell of base station notice UE configuration comprises following one or more: small-cell sign, small-cell frequency, small-cell index (index to the small-cell set employing of UE is put in assignment), the index of subordinate small-cell, base station (index that refers to the small-cell set that in whole macrocell, base station is controlled).
It should be noted that, if small-cell management entity calculates channel quality or the power of the upstream data receiving, the carrier frequency that the carrier frequency of using in the future due to small-cell management entity so and small-cell management entity receive UE upstream data differs larger, so can introduce compensating factor, differ for compensating the carrier frequency that receives the carrier frequency of UE upstream data and be UE service future due to small-cell management entity the profit and loss bringing compared with greatly.The value of compensating factor can be fixed value, and this value can be the empirical value of measuring in actual deployment, can be also the reference value that emulation obtains.Why compensating factor can be fixed, and is to consider that the coverage of small-cell is smaller, generally only has tens meters, so the excursion of the channel quality that carrier frequency difference causes or power is limited.
When practical application, the mode of operation shown in all right application drawing 3.In Fig. 3.Base station triggers small-cell management entity adopts base station down frequency to send measuring-signal, and the UE being operated in macrocell finds near small-cell by common frequency measurement, and the small-cell of discovery is reported to base station.The small-cell that base station reports from UE, selecting suitable small-cell is that UE is configured, and trigger configuration and in the downstream frequency of small-cell, send measuring-signal to the small-cell management entity of the small-cell of UE, small-cell management entity no longer sends measuring-signal in base station down frequency simultaneously.The small-cell that base station notice UE is its configuration, UE receives at the downstream frequency of small-cell the measuring-signal that small-cell management entity sends, and measurement result is reported to base station, and base station is that UE selects suitable small-cell to activate according to measurement result.
