Specific implementation mode

The cell selecting method of the embodiment of the present invention, primarily directed to the selection of enhancing cell.The enhancing cell, can be with It is to have to increase powerful cell, can also be the cell on new type carrier wave；For example, proposed in Release-11 versions NCT cells, the NCT cells can be the cell in enhanced non-backward compatible carrier waves, ESC cells, D2D cells etc..

In the embodiment of the present invention, UE is still to be carried out according to common cell-reselection procedure when carrying out cell selection, Such as including (due to being old process, so being no longer described in detail)：

Cell selects --- the most strong cell of selection：After UE bootings, some cell is selected to be resident first, it then could be The cell initiates business；UE can first carry out cell discovery, then select a signal strength most strong in multiple cells of discovery And/or the most strong cell of cell conduct that signal quality is best；

Cell selects --- cell selection criterion：It is accurate that UE judges whether most strong cell elected meets cell selection Then, for example whether meeting S criterion, if it is satisfied, then UE selects the cell resident；

Cell selects --- cell reselection：UE is after residing in cell, and with the movement of UE, UE can carry out cell reselection Replace resident cell；In the reuse adoption process, UE can also judge whether the cell that it to be replaced meets cell reselection criterion (example Such as R criterion), and the factors such as priority that can consider cell.

In the cell selecting method of the embodiment of the present invention, also flow can be selected to illustrate according to above-mentioned UE；But it is So that the UE of capabilities grade selects conventional cell, the UE selective enhancement cells as possible of ability grade, i.e., different energy as possible The UE of power grade is selected as possible and the cell of its function match, improves the utilization rate of radio resource, the cell of the embodiment of the present invention In selection method, enhances the cell selection parameters that the base station of cell is sent, ginseng corresponding with UE ability ratings is arranged to by base station Numerical value, by the effect of the parameter value so that the UE of different ability ratings has different selection knots to the same enhancing cell Fruit realizes above-mentioned purpose.The UE of the different ability ratings, such as can be the UE of different editions.It is most strong in the present invention Cell refers to the most strong and/or best signal quality cell of signal strength.

The cell selecting method of the embodiment of the present invention is specifically described below：

Embodiment one

Fig. 1 is the flow diagram of one embodiment of cell selecting method of the present invention, and this method is using UE as executive agent, such as Shown in Fig. 1, may include：

101, UE obtains the cell selection parameters that base station is sent, and the cell selection parameters are arranged to by the base station and institute State the corresponding parameter value of ability rating of UE；

Wherein, the parameter that the cell selection parameters are used required for referring in above-mentioned cell-reselection procedure, And UE will carry out the correlation computations of cell selection according to the cell selection parameters, and the parameter value of the cell selection parameters being capable of shadow Selection results of the UE to the cell is rung, such as selects or does not select.It is exemplified below several optional cell selection parameters, but this Field technology personnel are appreciated that in specific implementation, can also be other parameters, it is not limited to following parameter：

For example, the parameter (being properly termed as the first parameter) used in above-mentioned cell selection criterion (such as S criterion), needs The base station for enhancing cell is sent to UE, and UE carries out the calculating of criterion to determine whether to select the enhancing cell accordingly；

In another example can also be that parameter (can used in the cell reselection criterion (such as R criterion) in cell reselection process To be known as the second parameter), need the base station for enhancing cell to be sent to UE, UE carries out the calculating of cell reselection criterion to judge accordingly Whether to select the enhancing cell as the cell after replacing；

For another example can also be the priority parameters corresponding with the enhancing cell in cell reselection process, this is preferential The value of grade parameter is also corresponding with the ability rating of UE in setting；The priority parameters for example including：Enhance the frequency of cell The corresponding frequency priority parameter of rate, alternatively, the corresponding native region priority of enhancing cell, alternatively, the type of enhancing cell corresponds to Cell type priority etc..

Wherein, the so-called UE of the present embodiment obtains the cell selection parameters that the base station of enhancing cell is sent, and can be that UE is straight It connects from the base station of enhancing cell and obtains, can also be indirect acquisition, for example above-mentioned cell is selected ginseng by the base station of enhancing cell Number is sent to the serving cell where UE by the interface between base station, then is carried the parameter in system by the base station of serving cell UE is sent in information.

Wherein, the cell selection parameters are arranged to parameter value corresponding with the ability rating of UE, mean here, Cell selection parameters can be arranged to parameter value related with UE ability ratings by the base station of enhancing cell, so that UE should in basis When parameter value carries out cell selection, the UE selection results of different ability ratings are different.

For example, for needing the parameter a used in the calculating of S criterion, in the prior art, parameter a only has a number Value, that is, parameter value (for example the parameter value is a1), whether the UE of which kind of ability rating obtain the parameter value carry out S criterion meters It calculates, result of calculation is the same, is all to select the cell or do not select the cell.And in the present embodiment, enhance the base of cell It stands and is provided with two parameter values for parameter a, be first parameter value a2 corresponding with capabilities grade UE and and ability respectively The characteristics of corresponding second parameter value a3 of grade UE, the two parameter values is that capabilities grade UE can only read a2, cannot obtain To a3, and capabilities grade UE according to the a2 obtain after S criterion calculating the result is that relative to ability grade UE compared with Difficult selective enhancement cell；And ability grade UE can only read a3, cannot read a2, and ability grade UE is according to the a3 Carry out S criterion calculating after obtain the result is that being easier to select the enhancing cell relative to capabilities grade UE.As it can be seen that a2 is played The effect that capabilities grade UE selects threshold of the enhancing cell as Target cell is improved, a3 plays reduction ability Grade UE selects the effect of threshold of the enhancing cell as Target cell, promotes the matching of UE and cell function.

In another example in the example of the preceding paragraph, two parameter values can not also be arranged for parameter a by enhancing the base station of cell, Such as a parameter value a4 is only set, but parameter value a4 is that parameter value a4 is only compared to the characteristics of original parameter value a1 It can be read, and cannot be got by capabilities grade UE by ability grade UE；In this way, the UE of capabilities grade not can The calculating for enough carrying out S criterion, surely not selects the enhancing cell, and ability grade UE can get a4 and count accordingly S criterion are calculated, selective enhancement cell is just likely to.In this case, base station is to be arranged to parameter a and UE pairs of ability grade The parameter value answered, so that the enhancing cell is more advantageous to the selection of ability grade UE.

102, UE carries out cell selection processing according to the parameter value, decides whether to select the cell small as target Area.

Wherein, cell selection processing refers to the selection step in above-mentioned cell-reselection procedure, such as carries out The judgement of S criterion, the judgement of R criterion, at least one of the judgement of native region priority judge flow etc., are determined according to judging result Whether selective enhancement cell is as Target cell, the cell selected Target cell, that is, UE.The UE is according to the parameter value Cell selection processing is carried out, the UE of different ability ratings is different according to the selection result that parameter is worth to, and reference exampless can Referring to the description in 101 steps, to repeat no more.

Further, UE will also carry out cell before the cell selection parameters that the base station for obtaining enhancing cell is sent It was found that then just carrying out the processes such as selection, the cell reselection of most strong cell in the cell of discovery.So, UE has found that enhancing is small The method in area can be flexibly arranged, as follows：

For example, the base station of enhancing cell can send a kind of new downlink signaling, that is, find reference signaling (Discovery Reference Signals, referred to as：DRS), which is referred to as finding signaling (Discovery Signals, abbreviation： DS).It can be following at least one combination that the base station of enhancing cell, which is supplied to the signaling of UE,：The cell ginseng sent in full subframe Examine signal (Cell Rreference Signaling, abbreviation：CRS)；SS is (that is, PSS/SSS:PSS Primary Synchronization signal primary synchronization signals/SSS, the auxiliary synchronous letters of Secondary synchronization signal Number)；Channel state information reference signals (channel-state information reference signal, referred to as：CSI- RS)；DRS.UE carries out cell discovery and/or measurement using above at least one signaling combination.DRS therein is in unit The density occurred on frame can be high than present CRS density, the sending cycle of DRS can be than the hair of existing CRS, CSI-RS Send the period long.

Above-mentioned DRS, its physical sequence and/or the position on radio resource can be different from previous SS, still DRS may include SS functions；For example, in the downlink signaling that the base station of enhancing cell is sent, SS and CRS are not retransmited, and is sent out The DRS of the SS and CRS functions can be included by sending；Alternatively, the DRS is also SS, only with respect to original SS by PSS and SSS Relative position changed；Alternatively, base station both sends DRS, CRS is also sent, which includes SS functions, and CRS can be 5ms sends the CRS at interval.In addition, the type of DRS also there are many, such as following four：

Case 1a:The position of the DRS of all cells and pattern (position and pattern) are fixed.

Case 1B:The position of the DRS of each cell and pattern (position and pattern) are fixed；It is different Cell can be different.

Case 1c:The position of the DRS of each cell and pattern (including the DRS distribution patterns in unit subframe, Yi Jizi The emission pattern of interframe, if the period is to emit DRS in which subframe in 400ms, which does not send DRS) (position and Pattern it is) flexible, can configures；(sending cycle of the position of the subframe/PRB, DRS, figure Sample, and the density in some subframe)；Here DRS can be cell-level, can also be UE grades.

Case 1d:DRS resources are divided into two classes：One kind is fixed subset, and each cell is the same；One kind is spirit Subset living, each cell are different.Here DRS resources are to carry the resource of DRS information, the fixed subset i.e. position of the resource It is fixed to set, for example fixation is some RE carryings, and the position of the RE for the carrying DRS that flexible subset refers to is variation.

UE can receive the DRS that the base station of enhancing cell is sent, and find enhancing cell according to the DRS；For example, according to The position of DRS and drawing feature find enhancing cell；Alternatively, enhancing cell according to the DRS resource discoverings of the fixed subset of DRS Deng.

In another example as the downlink signaling that the base station for enhancing cell is sent with traditional cell is, for example, SS, CSI- RS etc., its physical sequence and/or the position on radio resource can be identical with previous SS, CSI-RS.Such case Under, UE can obtain the cell ID of enhancing cell in advance, and enhancing cell is found according to the cell ID.

The cell selecting method of the present embodiment, UE obtain the parameter of cell selection parameters corresponding with its own ability rating Value, and cell selection processing is carried out according to the parameter value, it will be able to selection result corresponding with its ability rating is obtained, to make The UE for obtaining different ability ratings selects the cell to match with its ability as possible, improves the utilization rate of radio resource.

201, cell selection parameters are arranged to parameter corresponding with the ability rating of user equipment (UE) by the base station of cell Value；

Wherein, the cell selection criterion (e.g., S criterion) that the cell selection parameters, e.g. cell use when selecting Required parameter (being properly termed as the first parameter) or related with cell priority parameters (e.g., frequency priority, cell Priority or cell type priority) or when cell reselection the cell reselection criterion (e.g., R criterion) that uses it is required Parameter (being properly termed as the second parameter) etc..

Cell selection parameters are arranged to parameter value corresponding with the ability rating of UE by the base station, for example, base station is set The first parameter value corresponding with the cell selection parameters and the second parameter value are set, first parameter value is for improving capabilities The UE of grade selects threshold of the enhancing cell as Target cell, and second parameter value is for reducing ability grade UE selects threshold of the enhancing cell as Target cell.

202, the cell selection parameters are sent to the UE by the base station, so that the UE is according to the parameter value Decide whether to select the cell as Target cell.

Wherein, UE will be calculated after the above-mentioned cell selection parameters for getting base station transmission according to the parameter, be determined Whether selective enhancement cell is as Target cell.For example, the UE of capabilities grade can only get it is corresponding with its ability rating First parameter value, and the second parameter value can not be got, it is obtaining the result is that phase after UE is calculated according to the first parameter value For the more difficult selection enhancing cells of ability grade UE.And the UE of ability grade can only get it is corresponding with its ability rating The second parameter value, and the first parameter value can not be got, UE can only be calculated according to the second parameter value, be obtained after calculating The result is that being easier to select the enhancing cell relative to capabilities grade UE.

The process that UE executes cell selection will be described in detail by several embodiments as follows：

Embodiment three

Fig. 3 is the flow diagram of the another embodiment of cell selecting method of the present invention, in the present embodiment, enhances the base of cell It stands and sends DRS, UE has found enhancing cell according to DRS, also, base station has sent priority ginseng corresponding with the ability rating of UE Number, UE are selected in cell reselection according to the priority parameters.As shown in figure 3, may include：

301, the serving cell where UE obtains the configuration information of the DRS of adjacent area by inter-base station interface；

Where it is assumed that the cell that UE is currently located is known as serving cell, and assume the neighboring community of the serving cell It is enhancing cell, then the base station of the serving cell and the base station of enhancing cell will be established and connected, and pass through the interface between base station, interaction The respectively cell information of lower cell；The cell information includes：The carrier wave frequency range of cell, carrier type, cell ID (identity, Mark), the information such as the configuration of DRS, can also include the cell selection parameters corresponding with cell that respective base station is sent.

Interface between the base station, e.g. X2 interface, wireless interface etc., can also be by other means in two bases Interactive information between standing.Optionally, in order to accelerate subsequent cell selection course, UE can also be before the selection of subsequent cell in advance The configuration information for obtaining some cells, such as synchronized relation, antenna port SS, CRS, CSI-RS and/or DRS are relevant with confidence Breath；DRS configuration informations therein include：(antenna port information can be antenna number and/or antenna port to antenna port information Number)；Frequency domain resource configuration information；Code domain resource allocation information；Subframe configuration information (including sub-frame offset information and period letter Breath)；And the ratio of the transimission power of the PDSCH and DRS of UE hypothesis；Can also include the synchronizing information for being measured cell, such as SFN shift/subframe shift/symbol shift ("/" be " and/or " relationship).These information can be that UE connects Inform UE's by way of broadcast or dedicated signaling in the adjacent area for receiving adjacent or with covering or similar-same to covering.

In addition, when establishing connection by S1 interfaces between base station, mobile management entity (mobility can be passed through Management entity, referred to as：MME Signalling exchange) is carried out, so that obtaining respective base station and adjacent between two base stations The cell information of each cell under base station.

302, UE receives the DRS that the base station of enhancing cell is sent, and finds enhancing cell using DRS, and from the small of discovery A strongest cell is selected in area；

Where it is assumed that it is enhancing cell that UE, which has multiple neighboring communities, UE sends the base station for receiving these enhancing cells Downlink signaling DRS, while if it is conventional cell that UE, which has neighboring community, UE can also receive the base station hair of these conventional cells The downlink signaling sent, such as SS or CRS etc..UE according to the position of DRS and drawing feature come find enhancing cell, i.e. DRS with The position of described SS, the CRS etc. and characteristics of image are different, then UE judges which cell is using difference between the two Conventional cell, which cell are enhancing cells.The position and drawing feature, i.e., DRS noted earlier is between subframe Emission pattern, the density etc. in some subframe.

The enhancing cell that UE has found may be multiple, and may also be found that multiple conventional cells simultaneously, then at this point, The UE of ability grade can consider that the priority of enhancing cell is higher, and the priority of conventional cell is relatively low, to preferentially increase Most strong cell is found in strong cell, capabilities grade UE thinks that the priority ratio enhancing cell of conventional cell is high, to preferentially exist Most strong cell is found in conventional cell；Alternatively, can also be set in advance as, capabilities grade UE can not identify that enhancing is small This new signalings of DRS that the base station in area is sent, and most strong cell can only be found in conventional cell.

For example, finding one most strong cell in enhancing cell for ability grade UE, UE is having found enhancing using DRS Cell and after carrying out Time and Frequency Synchronization, will carry out the comparison of subsequent most strong cell using the measured value of DRS, or using CRS, And/or the measured value of CSI-RS carries out the comparison of subsequent most strong cell, or utilize at least one in DRS, CRS, CSI-RS The measured value of item carries out the comparison of subsequent most strong cell.

303, UE judges whether the most strong cell of selection meets S criterion, selects the cell as suitable cell if meeting (suitable cell) is resident, otherwise, continually looks for other cells；

Wherein, for the present embodiment is using S criterion as cell selection criterion, the parameter needed in the calculating of the criterion can To be known as the first parameter, which is the new parameter for enhancing the base station of cell and sending, for example is the ginseng carried in DRS Number, e.g. Srxlev-e, Squal-e.Optionally, the UE that only ability grade can be arranged can just read first ginseng Number, and the calculating of S criterion is carried out, judge whether the strongest cell of selection meets S criterion：If it is satisfied, then selecting the cell It is resident as suitable cell；If conditions are not met, then the cell cannot be selected as suitable cell, other cells are continually looked for. And capabilities grade UE cannot read first parameter, can not carry out the calculating of S criterion, to which the enhancing cannot be selected small Area.

Optionally, above-mentioned new parameter (being, for example, Srxlev-e, Squal-e) can also be arranged can be by capabilities grade UE is read, and can also be read by ability grade UE, but there are two corresponding from different ability rating UE respectively for new parameter tool Parameter value, for example, first parameter value s1 corresponding with capabilities grade UE, the second parameter value corresponding with ability grade UE s2.That capabilities grade UE is read is s1, according to the s1 obtain the result is that the enhancing cell is not selected, to pass through the parameter The setting of value realizes the purpose for preventing capabilities grade UE from selecting the enhancing cell；That ability grade UE is read is s2, According to the s2 obtain the result is that select the enhancing cell, to be realized conducive to ability grade by the setting of the parameter value UE selects the purpose of the enhancing cell so that cell and the ability of UE match.In one section of example above, it is only capable of high The new parameter that ability rating UE is read, is the equal of parameter value corresponding with ability grade UE.

Optionally, this step can also use conventional treatment, that is, be not provided with new parameter, be all capabilities grade UE and high energy The parameter that power grade UE can be read, and similarly carry out the deterministic process of above-mentioned S criterion.Because of the cell of the embodiment of the present invention Selection method includes：The most strong cell of selection, S criterion judge and subsequent cell reselection step, as long as any one wherein A step can promote the matching of UE and cell function, for example all do not carry out related improve in the step of in front and prevent low energy Power grade UE selective enhancement cells, as long as but being prevented capabilities grade UE in subsequent cell reselection.

In the present embodiment, the required parameter of S criterion is that the system message of UE readings current service cell obtains, and is somebody's turn to do Parameter be before serving cell base station from enhancing cell base station obtain.

304, UE carries out cell reselection according to priority parameters corresponding with enhancing cell；

Wherein, even if UE has selected to will continue to carry out cell reselection if the suitable cell in 303, to keep oneself always It is in the higher cell of service quality.During cell reselection, UE should consider the priority parameters of each alternative cell, also want The calculating of cell reselection criterion is carried out according to the cell selection parameters of alternative cell.Since cell reselection process is routine techniques, The present embodiment is no longer detailed, is only described as follows to being related to improved reuse adoption process：

In the present embodiment, the base station pair priority parameters corresponding with enhancing cell for enhancing cell have carried out improving setting. The priority parameters, such as can enhance the corresponding frequency priority of frequency of cell, or enhancing cell is corresponding Native region priority, or the corresponding cell type priority of enhancing cell type.

For example, the base station of enhancing cell, which can be enhancing cell, is arranged frequency priority, and it is arranged for the frequency priority Two parameter values corresponding with the ability rating of UE, one is that (R8/R9's is excellent for the first parameter value corresponding with capabilities grade UE First grade), this parameter value configures relatively low, that is, takes low rank value；The other is corresponding with ability grade UE second Parameter value (e.g., priority for m (m:NCT, ESC or D2D etc.)), this parameter value configures relatively high, that is, takes high Grade value.Capabilities grade UE does not have the powerful ability of increasing for supporting enhancing cell, can not read the second parameter value, can only Read the first parameter value, and due to first parameter value configure relatively low (taking low rank value) so that UE to decide not to selective enhancement small Area；Ability grade UE supports the enhancing function of enhancing cell, can read the second parameter value, and since second parameter value is matched Higher (taking high-grade value) is set so that UE determines selective enhancement cell.

In another example the base station for enhancing cell may be that enhancing cell setting native region priority or cell type are preferential Grade, each priority are also respectively provided with two parameter values, and set-up mode is similar with one section above, is no longer described in detail.The cell preference Either cell type priority can be that the base station of enhancing cell is informed by way of broadcast message or dedicated signaling to grade UE, UE are after receiving these parameters, in the judging process for doing cell reselection, just consider the comparison of above-mentioned priority parameters.

In addition, in the value mode of priority parameters, if the ability rating of UE matched with the ability of cell (such as UE and Cell all supports certain function), then priority parameters are taken into high-grade value；If the ability rating of UE and the ability of cell mismatch (such as UE supports function a, cell to support function a and b), then priority parameters are taken low rank value.For example, the base station of cell can Think that two values, i.e. low rank value and high-grade value are arranged in priority parameters；For UE, UE is if it is determined that the energy of oneself Power grade is matched with the ability of cell, then can read high-grade value therein；UE if it is determined that the ability rating of oneself with it is small The ability in area mismatches, then can read low rank value therein.

The value of the priority parameters, in specific implementation can be there are many mode.For example, 0 or 1 can be taken, than Such as inferior grade is indicated with 0,1 indicates high-grade；Alternatively, 0 can also be taken, to any one natural number between n, (wherein, n indicates one A natural number), and determine according to the size of natural number the height of grade, for example, inferior grade takes 2, it is high-grade to take 5.

The DRS that is sent using cell base station mainly for UE below has found that cell illustrates, in the present embodiment, cell Base station send DRS, UE has found cell according to DRS, also, base station has sent priority ginseng corresponding with the ability rating of UE Number, UE are selected in cell reselection according to the priority parameters.It can equally illustrate in conjunction with Fig. 3, may include：

301, the serving cell where UE by inter-base station interface obtains the configuration information of DRS of adjacent area (step can Choosing)；

302, the base station of cell can send a kind of new downlink signaling, that is, find reference signaling (Discovery Reference Signals, referred to as：DRS), which is referred to as finding signaling (Discovery Signals, abbreviation： DS).It can be following at least one combination that the base station of cell, which is supplied to the signaling of UE,：The cell reference letter sent in full subframe Number (Cell Rreference Signaling, referred to as：CRS)；SS is (that is, PSS/SSS:PSS Primary Synchronization signal primary synchronization signals/SSS, the auxiliary synchronous letters of Secondary synchronization signal Number)；Channel state information reference signals (channel-state information reference signal, referred to as：CSI- RS)；DRS.UE carries out cell discovery and/or measurement using above at least one signaling combination.DRS therein is in unit The density occurred on frame can be high than present CRS density, the sending cycle of DRS can be than the hair of existing CRS, CSI-RS Send the period long.

Above-mentioned DRS, its physical sequence and/or the position on radio resource can be different from previous SS, still DRS may include SS functions；For example, in the downlink signaling that the base station of cell is sent, SS and CRS are not retransmited, and sends energy Enough include the DRS of the SS and CRS functions；Alternatively, the DRS is also SS, only with respect to original SS by the phase of PSS and SSS Position is changed；Alternatively, base station both sends DRS, CRS is also sent, which includes SS functions, and CRS can be 5ms hairs Send the CRS at interval.In addition, the type of DRS also there are many, such as following four：

Introduce step 303；

The UE receives the DRS according to the information of the DRS of storage；

Alternatively, the UE receives institute according to the information of the DRS of the cell obtained from the system message of serving cell State DRS；

Alternatively, the information of the DRS of the cell is obtained in the dedicated signaling that the UE is sent by the base station of serving cell, And the DRS is received according to the information of the DRS；

Alternatively, the UE obtains the letter of the DRS of the corresponding cell according to the Physical Cell Identifier PCI of the cell Breath, and the DRS is received according to the information of the DRS；

Alternatively, the UE receives the DRS according to the DRS information of the fixed subset of the DRS.

For example, the information of above-mentioned DRS includes position and the drawing feature information of the DRS.

Introduce step 303.

The UE receives the DRS according to the information of the DRS of storage；

Introduce step 303.

UE can receive the DRS that the base station of cell is sent according to the information of the fixed subset of DRS, and according to the DRS The information of fixed subset find cell；For example, finding cell according to the position of DRS and drawing feature；Alternatively, according to DRS DRS resource discovering cells of fixed subset etc..

After the system message or specific messages that can receive the cell, the flexible son of DRS resources is further obtained Collection.

Introduce step 303.

Case 1e:As the downlink signaling that the base station of cell is sent with traditional cell is, for example, SS, CSI-RS Deng its physical sequence and/or the position on radio resource can be identical with previous SS, CSI-RS.In this case, UE can obtain the cell ID of cell in advance, and cell is found according to the cell ID.Then, it then goes to read DRS.

Introduce step 303.

303, UE receives the DRS that the base station of cell is sent, and finds cell using DRS, and selected from the cell of discovery One strongest cell；

Where it is assumed that it is enhancing cell that UE, which has multiple neighboring communities, UE sends the base station for receiving these enhancing cells Downlink signaling DRS, while if it is conventional cell that UE, which has neighboring community, UE can also receive the base station hair of these conventional cells The downlink signaling sent, such as SS or CRS etc..UE has found cell according to the position of DRS and drawing feature, i.e. DRS with it is described SS, CRS etc. position and characteristics of image be different, then UE judges which cell is tradition using difference between the two Cell, which cell are enhancing cells.The position and drawing feature, i.e., transmittings of the DRS noted earlier between subframe Pattern, the density etc. in some subframe.

The enhancing cell that UE has found may be multiple, and may also be found that multiple conventional cells and multiple enhancings simultaneously Cell, then at this point, the UE of ability grade can consider that the priority of enhancing cell is higher, the priority of conventional cell compared with Low, to preferentially find most strong cell in enhancing cell, i.e. the priority ratio of the UE setting enhancing cells of ability grade passes The priority for cell of uniting is high, and most strong cell is selected in the enhancing cell.Further, the UE of optional ability grade is increasing When can not find available cell in strong cell and can not find most strong cell, just go in conventional cell to find available most strong cell.

Capabilities grade UE thinks that the priority ratio enhancing cell of conventional cell is high, to preferentially be found in conventional cell The priority of most strong cell, i.e. the priority ratio enhancing cell of the UE settings conventional cell of capabilities grade is high, in the tradition Most strong cell is selected in cell；Alternatively, can also be set in advance as, capabilities grade UE can not identify the base station of cell This new signalings of DRS of transmission, and most strong cell can only be found in conventional cell.Wherein, most strong cell can be defined as small The signal power in area is most strong and/or interference is minimum or cell signal meets the condition of some formula.

Alternatively, the UE with transmission DRS cell function match, high priority is set as by the priority for the cell for sending DRS； And/or with send the DRS unmatched UE of cell function, the priority for the cell for sending DRS is set as low priority.

For example, finding one most strong cell in the cell for ability grade UE, UE is having found that cell is gone forward side by side using DRS After row Time and Frequency Synchronization, the comparison of subsequent most strong cell will be carried out using the measured value of DRS, or utilize CRS, and/or CSI- The measured value of RS carries out the comparison of subsequent most strong cell, or utilizes the measured value of at least one in DRS, CRS, CSI-RS Carry out the comparison of subsequent most strong cell.

The embodiment of the present invention is also provided separately a kind of cell selecting method, and UE receives what the base station of cell was sent in this method Downlink finds reference signaling DRS；The cell is found according to the DRS；And select the cell.

Optionally, the UE of the ability grade selects most strong cell in the enhancing cell, including：

If the UE of the ability grade can not find the most strong cell in the enhancing cell, go the tradition small Most strong cell described in being found in area.

Example IV

Fig. 4 is the cell reselection schematic diagram in the another embodiment of cell selecting method of the present invention, it is assumed that figure In UE-A be a tradition UE (i.e. the UE of capabilities grade), UE-B and UE-C be novel UE (i.e. the UE of ability grade), Cell1 and cell2 is conventional cell, and cell3, cell4 and cell5 are enhancing cell (being, for example, NCT cells).

In UE-A, for example, cell1 is higher priority, cell3 and cell5 are lower priorities, because The priority value of the read enhancing cell cell3 and cell5 of UE-A is exemplified below by the relatively low of base station configuration：Assuming that The priority value for the conventional cell cell1 that UE-A is read is P1=5, and the priority value for the enhancing cell cell3 that UE-A is read is (it is the first parameter value that the UE-A that base station is capabilities grade is configured to be somebody's turn to do " 3 " to P2=3, and what can be configured is more slightly lower than general value P1 A bit), then UE-A compares the priority value of cell1 and cell3, and certainly the priority of cell1 ratios cell3 is high, and UE-A will be selected Cell1 is selected, i.e. the setting of P2=3 is so that the UE of capabilities grade is easier to select the conventional cell with its function match.

Similar with above-mentioned reason, in UE-B, the priority value that also can receive conventional cell cell1 is P1=5, Also the priority value for reading enhancing cell cell3 is that P3=7 (is somebody's turn to do " 7 " are the UE-B configurations that base station is ability grade second Parameter value, what can be configured is more slightly higher than general value P1), then UE-B compares the priority value of cell1 and cell3, certainly cell3 ratios The priority of cell1 is high, and UE-B will select cell3, i.e. the setting of P3=7 so that the UE of ability grade be easier to select with The enhancing cell of its function match.

Example IV

The present embodiment is compared with embodiment three, and in UE cell reselections, required second is calculated to cell reselection criterion Parameter is improved, and improved procedure is similar with the improvement of above-mentioned priority parameters.

For example, in cell reselection, for carrying out cell reselection between the cell of same frequency and equal priority frequency When, need the calculating for executing cell reselection criterion (such as R criterion).The present embodiment is similarly the relevant calculating parameter of R criterion At least one of, it is provided with two parameter values；It, can be with for example, for the parameter Qmeans and Qoffset that are used in R criterion Two parameter values are respectively set, including：First parameter value q1 and UE with ability grade corresponding with capabilities grade UE Corresponding second parameter value q2 so that capabilities grade UE is only capable of reading q1, and prevents capabilities grade UE from selecting institute using q1 State enhancing cell so that ability grade UE is only capable of reading q2, and is conducive to ability grade UE selective enhancement cells using q2.

It is optionally, above-mentioned that two parameter values q1 and q2 are arranged to some parameter (for example, cell selection parameters Qmeans), In specific implementation, the two different parameter values can also be to be indicated respectively with two different parameters, such as Qmeans= Q1, and introduce new parameter Qmeans-m=q2.

It is exemplified below：Enhance at least one of the relevant calculating parameter of rank criterion of cell (such as NCT cells), (e.g., Qmeas, Qoffset value), introduce new parameter, such as Qmeas-m, Qoffset-m (m：NCT, ESC or D2D, etc.).

Traditional parameter, such as Qmeas, Qoffset (parameter of R8/R9)：This parameter can be by traditional UE (i.e. capabilities Grade UE) it reads, this one kind UE, which does not have, supports the corresponding enhancing function of enhancing cell, and can not read the parameter newly introduced Value, the configuration of this kind of value enable capabilities grade UE to be easier to be selected into conventional cell, that is, more difficult to be selected into enhancing cell.

New parameter, such as Qmeas-m, Qoffset-m (m：NCT, ESC or D2D, etc.)：The meeting of this parameter can be novel UE (i.e. ability grade UE) read, this one kind UE supports to enhance the corresponding enhancing function of cell, and can read and newly draw The configuration of the parameter value entered, this kind of value enables ability grade UE to be easier to be selected into enhancing cell.

Equally by taking the schematic diagram of Fig. 4 as an example, UE-A can only read traditional Qmeas, the cell of Qoffset, these parameters Configuration so that UE-A is easier to select the cell1 in cell2 or f3 in f2 as persistent district.UE-B can be read New parameter such as Qmeas-m, the cell of Qoffset-m, the configuration of these parameters so that UE-B is easier to select in f2 Cell3 or cell5 is resident.If UE resides in F2, it will support the hybrid-sorting of CRS values and DRS values.

The scheme of embodiment three can equally be well applied to the present embodiment, for example, in cell reselection process, both can individually adopt With to priority parameters improved plan, can also individually be used described in embodiment described in the present embodiment to R criteria parameters Improved plan, or can also priority parameters and R criteria parameters be improved.

Embodiment five

In the present embodiment, relative to above-described embodiment, difference lies in the DRS resources for enhancing the base station transmission of cell are divided At two classes, one is fixed subset, and each cell is the same, and one kind is flexible subset, and each cell is different.So In this case, DRS resources in the fixed subset in UE can be gathered using DRS find enhancing cell, also, UE into Can be the comparison that follow-up most strong cell is carried out using the DRS resources in fixed subset when the comparison of the most strong cell of row, alternatively, The comparison of most strong cell is carried out using the measured value of CRS, and/or CSI-RS, alternatively, in the fixed subset in gathering using DRS DRS resources, in CRS, CSI-RS at least one of measured value carry out most strong cell and compare.

In addition, in the calculating of cell selection criterion, following scheme may be used in the UE of the present embodiment：

For example, UE reads the system message of current area, the parameter needed for cell selection criterion (S criterion) is obtained, e.g., Srxlev/Squal or Srxlev-e/Squal-e, the measured values of the DRS resources in the fixed subset in being gathered using DRS are sentenced Whether the most strong cell of disconnected selection meets S criterion, and (i.e. parameter value is using the DRS resources in the fixed subset in gathering from DRS Measured value, only the parameter value can be indicated with Srxlev/Squal, can also be indicated with Srxlev-e/Squal-e；It is optional , when being indicated with Srxlev/Squal, both it can be read or be read by ability grade UE, the parameter value by capabilities grade UE Two parameter values including corresponding to different ability rating UE respectively；It, can be only by high energy when being indicated with Srxlev-e/Squal-e Power grade UE is read)：If it is satisfied, then selecting the cell resident as suitable cell；If conditions are not met, cannot then select this Cell continually looks for other cells as suitable cell.

In another example UE reads the system message of current area, the parameter needed for cell selection criterion (S criterion) is obtained, e.g., The complete or collected works of the Srxlev/Squal or Srxlev-e/Squal-e and DRS of current area configurations, the complete or collected works configured using DRS In the measured values of DRS resources judge whether the strongest cell of selection meets S criterion：If it is satisfied, then selecting the cell It is resident as suitable cell；If conditions are not met, then the cell cannot be selected as suitable cell, it is small to continually look for other Area.

Further, in cell reselection process, the UE of the present embodiment can be provided using the DRS in the complete or collected works of DRS configurations The measured value in source carries out the judgement of R criterion；Required cell choosing is calculated for example, the measured value of the DRS resources can be R criterion The parameter value of parameter is selected, which can only be read by ability grade UE, can also be including can be by capabilities etc. The first parameter value that grade UE is read and the second parameter value that can be read by ability grade UE.
