For example, network side equipment determines the first user equipment according to the corresponding relationship of distance range and reception power bracket Reception power bracket corresponding with distance range belonging to second user equipment.Distance range and the corresponding pass for receiving power bracket System can provide in the protocol, can also be determined by network side equipment or high-level device.

For example network side equipment can also reporting according to information such as the D2D UE reception conditions of same position or distance And collection, the mean value or empirical value of situation are reported, according to D2D UE either substantially to estimate the range for receiving power

Preferably, network side equipment can also send in above-mentioned one~tri- for the first user equipment and second user equipment D2D messaging parameter；

Correspondingly, the first user equipment is sent in the corresponding resource of resource scheduling information according to D2D messaging parameter is sent D2D data；

Second user equipment receives D2D number according to D2D messaging parameter is sent in the corresponding resource of resource scheduling information According to.

Wherein, D2D messaging parameter includes but is not limited to some or all of in following:

Modulating-coding format sends power.

For example size, the type of D2D data etc. that network side equipment can need to send according to the first user equipment determine D2D messaging parameter.

Such as transmission power is mainly influenced by D2D communication range, for the biggish UE of D2D communication range of request, is needed Biggish transmission power is distributed, conversely, for the lesser UE of D2D communication range of request, needs to distribute lesser transmission function Rate, transmission power is also related with the ability of UE simultaneously, cannot exceed UE ability, and sends power and also need to consider network entirety Disturbed condition or UE around disturbed condition etc..Compare serious situation in interference, sending power should be lower, In the case that interference is light, sending power can suitably be increased.

For modulating-coding format, need to consider that the resource that can be distributed to the D2D user there are much, to need to send numbers Comprehensive to determine according to the factors such as size and expected received signal to noise ratio, communication range, the specific algorithm of different realizations is not yet Together.

In an implementation, the network side equipment of the embodiment of the present invention can be the first user using dynamic or semi-static mode The device configuration D2D communication resource.

Dynamic dispatching is can be scheduled according to the sequential relationship of dynamic dispatching and dynamic dispatching.Such as dynamic dispatching Can reporting according to UE, according to the business feature of outgoing data amount size and resource occupation and UE, rate behavior etc. of contracting, With dispatching algorithm, dynamic resource allocation is carried out to UE, dynamic resource is then sent to UE using PDCCH mode.

Specifically, network side equipment can be pre-configured with D2D broadcast communication at the time of occur, for example, the period and Pattern can notify all user equipmenies by SIB system information.User equipment only needs to carry out in particular moment in this way Monitor simultaneously resolution scheduling signaling.Wherein, dispatch can be scheduled multiple subframes.

In order to save user equipment power consumption and processing complexity, semi-persistent scheduling can also be used.Semi-persistent scheduling has more Kind mode.

One, network side equipment broadcast allocation semi-persistent resource complete or collected works, corresponding segmentation information and resource identification, and pass through use Family device-specific signals the corresponding resource identification of user equipment.

Two, network side equipment signals the corresponding D2D communication resource of user equipment by user equipment specific, and broadcasts The D2D communication resource of all special user equipments, wherein special user equipment is not need when sending D2D data to receiving end The user equipment that user equipment is authenticated.

In aforesaid way, semi-persistent resource is distributed by dedicated signaling, i.e. the user equipment money of having known oneself What source is, resource scheduling information serves as the switch of the semi-persistent resource, such as when UE has data, and network side equipment can be with The mark that " start or activate " is carried using PDCCH signaling informs that half distributed before user equipment can begin to use is quiet State resource, until network side judges that resource UE is no longer needed using can equally use the mark of " stop or deactivate ", announcement Know that UE is subsequent no longer to the semi-persistent resource user.

That is, after semi-persistent resource distributes, resource scheduling information is served only for activating/not activation notification, i.e., When the semi-persistent resource distributed before control can be used, and when cannot use.

Several semi-static examples are set forth below:

1, resource has number:

It is pre-configured with semi-persistent resource used in D2D broadcast communication, network side equipment can be logical by SIB system information Know all user equipmenies, and these resources are numbered.In actual use, network side according to the D2D of user request or Service request (being three process of layer or higher process), UE is notified in the form of dedicated signaling, which semi-persistent resource is distributed The UE is given, the number of resource can be directly notified, can also notify the specifying information of resource.

2, resource is without number:

It is pre-configured with semi-persistent resource used in D2D broadcast communication, network side equipment can be logical by SIB system information Know all user equipmenies.

To the transmission user equipment of each request resource, network side equipment can transmission according to business feature, to needs User equipment distributes the user equipment exclusive semi-persistent resource in a manner of dedicated signaling, this semi-persistent resource needs belong to The a subset of the semi-persistent resource set notified in SIB system information, after distribution, network side equipment is wirelessly faced with special again When identifier scramble resource scheduling information, notifying user equipment is activated behaviour such as (or deactivations) to dedicated semi-persistent resource Make, the resource that guidance sends user equipment uses.

For receiving user equipment, the semi-persistent resource set that network side equipment can be broadcasted directly in SIB message.It connects User equipment is received to carry out receiving data trial in each resource in semi-persistent resource set.Further, for being in The reception user equipment of connected state, network side equipment can be sentenced according to the distance for receiving user equipment and each transmission user equipment It is disconnected, the resource used in the close transmission user equipment is informed with dedicated signaling and receives user equipment, in this way reception user Equipment can be received purposefully, avoid the search in wholly-owned source range.

Several examples are set forth below the solution of the present invention is described in detail.

Following embodiment illustrates distribution and use process to D2D broadcast communication resource with LTE system,

Other systems are similar with LTE system process, and details are not described herein.

Example one:

Common source scheduling information is scrambled in cell, i.e. all user equipmenies in a cell correspond to identical one A or multiple special wireless temporary identifiers.

Wherein, the resource scheduling information shared in cell is scrambled, and can take system default, such as in standard agreement Middle regulation；Broadcast message notifying user equipment can also be passed through by network side equipment.

In an implementation, the present embodiment, which carries out scrambled special wireless temporary identifier, can be for D2D dynamic broadcast biography The B-RNTI of defeated scheduling and/or SPS-RNTI for D2D semi-static broadcast transmitting and scheduling.

When UE wishes that peripherad UE sends D2D broadcast communication data, needs to report request to network and/or report certainly Oneself needs the data volume size transmitted.Network carries out the scheduling of the D2D communication resource to the UE.After UE receives the resource, referring to Determine to send D2D broadcast data in resource；

For receive UE for, it is any have the ability and it is desirable that receive D2D broadcast communication data UE, may be by shifting to an earlier date The resource scheduling information of acquisition parses the dispatch in PDCCH, if being decoded to correct D2D broadcast scheduling, It attempts to receive in the resource of scheduling, if received, completes the reception of a D2D broadcast data.

Specific step is as follows:

Step 0: network side is in the SIB form to broadcast the message or in the form of using standard default, by the special of this cell Wireless temporary identifier informs UE.Optionally, the D2D communication resource can also be configured for UE using dynamic or semi-static mode.

In an implementation, if network side does not inform that the semi-static communication resource of UE D2D, network side can only use dynamic dispatching, Dynamically divide resource to UE every time, and resource location needs to send out every time, expense is larger.It is (i.e. semi-static if pre-configuration Configuration), resource is disposably pre-configured can be periodically to UE(), UE is voluntarily used, and saves signaling, but to the business mould of UE Formula (Pattern) requires, and must have some cycles.

Here standard default is exactly some the specific RNTI clearly write out in a standard for D2D broadcast communication.

Step 1: sending UE(and refer to D2D broadcast communications capability and it is desirable that transmit the UE of D2D broadcast communication data), hair It before sending D2D broadcast communication data, needs to enter connected state, the request for carrying out D2D transmission is sent to network side (preferably, should The communication type that request can be carried in request, the information etc. authenticated to core net).

It for network side equipment, needs according to information such as the communication types of request, D2D broadcast communication receiving is carried out to the UE Processing, and dedicated signaling process is used, a dedicated ID is distributed for the UE, the ID is to distinguish UE in scheduling.Optionally, Network side equipment can configure some dedicated periodic resources, and similar semi-static scheduling resources configure.

If dynamic configuration resource, UE listens scheduling every time, then uses resource transmission.If predistribution, UE can be with According to the period of pre-configuration, used according to established rule.

Configuring the semi-static communication resource of D2D for step 0 for UE is uniformly to be configured to the semi-static communication resource set of D2D, The configuration that any UE can be received, especially for receiving end UE.For example network side equipment is by all transmitting terminal UE The intersection being semi-statically configured broadcasted, such receiving end UE can all positions attempt decode.

Step 1 is that the UE configuration D2D communication resource is configured to transmitting terminal UE individual, that is to say, that transmitting terminal UE needs Which the resource D2D communication for knowing oneself as actually.

Step 2: sending the confirmation signaling that UE receives network side equipment, such as receive D2D configuration (configuration) After signaling etc., when there is D2D broadcast data to need to send, resource scheduling request is carried out to network side and/or reports oneself Outgoing data amount size.

Scheduling request has been implied if only carrying out data volume and reporting.In an implementation, data volume reports information more comprehensively, And the benefit of scheduling request is simple.

Step 3: for network side equipment when receiving resource scheduling request and/or outgoing data amount size, the UE is given in determination The D2D communication resource of distribution, can be dynamic resource allocation, the semi-static scheduling resources configured before can also be swashed It is living.

For example know outgoing data amount size, the efficiency that would be even more beneficial to scheduling is taken when the business feature according to UE , then can be according to the data volume size actually reported when being dynamic dispatching configuration, in conjunction with resource and dispatching algorithm etc., decision is how Dynamic allocation of resources；

For example do not know outgoing data amount size, generally correspond to semi-persistent scheduling, it may be possible to which the business of UE has certain biography Defeated rate rule, has been configured semi-persistent resource before, once scheduling request is received, this means that the data burst of UE arrives It reaches, then activates semi-persistent resource.

Step 4: network side equipment is carried out the resource scheduling information for sending UE is distributed to special wireless temporary identifier Scrambling (for example being that dynamic dispatching is then scrambled in the form of B-RNTI, be that semi-persistent scheduling is then scrambled in the form of SPS-RNTI), and with The form of descending scheduling signaling is sent.Preferably, UE is in step 1 for the carrying of the display transmission inside dispatch The dedicated ID of distribution, to indicate that the resource is allocated to specified transmission UE.

Preferably, network side equipment can also will send parameter configuration to UE, such as modulating-coding format, transmission power Deng.

Wherein, modulating-coding format etc., can be according to the communication distance of UE, the survey of network overall interference situation or even UE Amount reports situation etc., carries out comprehensive assessment, final to determine which kind of modulating-coding format used.

Step 5: sending UE with special wireless temporary identifier (such as B-RNTI or SPS-RNTI) and decode descending scheduling Signaling simultaneously parses, if it find that there is one's own dedicated D2D broadcast communication scheduling, (for example judge to carry in dispatch Whether ID is oneself dedicated ID), then with specified transmission parameter, such as modulating-coding in the resource that network side equipment is specified Format, transmission power etc. send D2D broadcast data.

If network side equipment does not configure transmission parameter, UE itself, which is determined, sends parameter.

Step 6: receiving UE(and refer to the UE with D2D communication or D2D receive capabilities and it is desirable that receive D2D broadcast data), On all scheduling resource locations, the special wireless temporary identifier that can be obtained with oneself (such as B-RNTI or SPS- RNTI it) decodes descending scheduling signaling and parses, if parsing is correct, receives UE and connect in the resource that dispatch indicates It receives and decodes D2D broadcast communication data, if receiving and decoding correct, then it is assumed that receive D2D broadcast communication data.

Preferably, network side equipment can also inform that receive UE sends parameter accordingly.

In this way, receiving UE only need to receive and be decoded according to parameter is sent.If not configuring transmission parameter, connect It receives UE and needs blind examination, attempt to traverse all possible situation.

Preferably, the UE can be wished that the requirement for receiving D2D broadcast data refers to for the reception UE for being in connected state Show and reported to network side equipment, such as 1bit, shows to wish to receive D2D broadcast data, then network side equipment can be according to the UE It requests the position as the UE sent to carry out calculating distance in location, with cell, will meet at a distance from reception UE The privately owned ID of the transmission UE of certain condition (such as distance is less than some thresholding and regards as approaching) informs reception UE, receives in this way UE is when receiving public D2D broadcast scheduling signaling, it is only necessary in the corresponding scheduling resource of ID with oneself close transmission UE On carry out attempt receive the decode, reduce the processing complexity of UE.

Preferably, network side equipment receives power according to receiving UE and sending at a distance from UE, for second user device configuration Range.

Example two:

One group of UE uses one or more dedicated RNTI.That is all first user equipmenies pair in a group of user equipments Answer the identical special wireless temporary identifier of one or more.

When one group of UE is directed to the scheduling of D2D broadcast communication using one or more dedicated RNTI instruction in cell, The UE group that UE is added is informed by dedicated signaling by eNB, and for the configuration (such as group identify) of the group, organize corresponding Special wireless temporary identifier (such as G-RNTI(Group RNTI) and/or SPS-RNTI).Preferably, the UE can also be informed Mark in this group, to distinguish different UE in scheduling.

For receiving for UE, limitation (Restricted) can be divided into and be added and open (Open) addition, the former needs Network authenticates the reception UE of addition, and a group configuration can be informed by only authenticating successful UE, can generally use dedicated signaling Process；If it is the addition of Open, then UE is not limited, as long as the neighbouring UE that can receive can be carried out receiving, can led at this time The mode for crossing SIB signaling broadcasts all groups of configuration, can also be remote according to position each other simultaneously for the UE of connected state Closely, reception UE is further assisted to inform it close to which group, so that UE specially parses the scheduling information and data packet of these groups ?.

When UE wishes that peripherad UE sends D2D broadcast communication data, it is necessary first to request is reported to network, by network Side apparatus judges according to the distance between UE, if has and has built up, and the group close from the UE, if so, then by the UE It is incorporated to the group, and notifies ID in the information of the UE group and dedicated group of UE in a manner of dedicated signaling, it is subsequent by network side equipment pair The UE carries out the scheduling of the D2D communication resource, and after receiving the resource, UE sends D2D broadcast data in specified resource.

For receive UE for, it is any have the ability and it is desirable that receive D2D broadcast communication data UE, may be by shifting to an earlier date Public the G-RNTI perhaps SPS-RNTI or privately owned G-RNTI, SPS-RNTI etc. obtained, to the dispatch in PDCCH It is parsed, if being decoded to correct D2D broadcast scheduling, carries out trial reception on the resource, if receiving and solving Code is correct, then completes the reception of a D2D broadcast data.

For Open group Adding Way, the specific steps are as follows:

Step 1: sending UE(and refer to D2D broadcast communications capability and it is desirable that transmit the UE of D2D broadcast communication data), hair It before sending D2D broadcast communication data, needs to enter connected state, carries out D2D transmission request (preferably, in the request to network side The communication type of request can be carried, including is authenticated etc. to core net).

It for network side equipment, needs according to information such as the communication types of request, D2D broadcast communication receiving is carried out to the UE Processing, and judge whether there be established group around UE according to the position of UE, if so, the UE is directly then divided into the group And inform the configuration of the group, if not provided, establishing a new group, dedicated signaling is used later, by the group configuration information of the UE UE is notified with ID dedicated in group, wherein group configuration may include a group ID, for the special wireless temporary identifier in configuration group When distinguish different groups of special wireless temporary identifier, ID is to distinguish UE in scheduling in the group of the UE.Optionally, network side Equipment can configure some dedicated periodic resources, and similar semi-static scheduling resources configure.

Such as the corresponding RNTI1 of such as group 1, corresponding RNTI2 of group 2 etc..In addition, group configuration can also include the attribute letter of group Breath, such as open group or limitation group or even specific people, such as the corresponding public security officer of group 1, corresponding traffic police personnel of group 2 etc..

For group information corresponding to the group built up, such as group mark, the information such as special wireless temporary identifier, net Network side apparatus can notifies in a manner of broadcast message to other UE in cell, and when group changing, updates the broadcasted content.

Step 6: receiving UE(and refer to the UE with D2D communication or D2D receive capabilities and it is desirable that receive D2D broadcast data), On all scheduling resource locations, the special wireless temporary identifier that can be obtained with oneself (such as B-RNTI or SPS- RNTI it) decodes descending scheduling signaling and parses, receive UE and receive and be decoded, if receiving and decoding correct, then it is assumed that connect Receive D2D broadcast communication data.

Preferably, the UE can be wished that the requirement for receiving D2D broadcast data refers to for the reception UE for being in connected state Show and network side eNB, such as 1bit is given to report, shows to wish to receive D2D broadcast data.Network side equipment can be according to locating for the UE Position, carry out calculating distance as the position of UE sent with request in cell, will meet centainly at a distance from reception UE ID in the affiliated group information of transmission UE and the group of transmission UE of condition (such as distance is less than some thresholding and regards as approaching) Inform reception UE, reception UE in this way is when receiving public D2D broadcast scheduling signaling, it is only necessary to oneself close transmission It carries out attempting to receive the decode in the corresponding scheduling resource of the group and ID of UE, reduces the processing complexity of UE.It is another Mode, network side equipment inform the information for receiving the close group of UE by dedicated signaling, without specific to some UE in group, this Sample, for the scheduling of all transmissions of the group, can go to receive for receiving for UE.

For Restricted group Adding Way, the specific steps are as follows:

It for network side equipment, needs according to information such as the communication types of request, D2D broadcast communication receiving is carried out to the UE Processing, and judge whether there be established group around UE according to the position of UE, if so, being then directed to the group of surrounding to the UE Authentication process is carried out, the UE is divided into the group after the condition that the group is added is met in UE and informs the configuration of the group, if not provided, A new group is established, uses dedicated signaling later, dedicated ID in the group configuration information of the UE and group is notified into UE, wherein group Configuration may include a group ID, for distinguishing different groups of special wireless interim mark in the special wireless temporary identifier of configuration group Know symbol, ID is to distinguish UE in scheduling in the group of the UE.Optionally, network side equipment can configure some dedicated periodic moneys Source, similar semi-static scheduling resources configure.

Preferably, network side equipment can be judged at a distance from group according to UE, selection distance is less than given threshold Group, and UE is authenticated；If newly establishing a group without if.

Step 6: receiving UE and refer to the UE with D2D communication or D2D receive capabilities and it is desirable that receive D2D broadcast data), exist When wishing to receive the information of some Restricted Group, needs first to carry out the authentication for group to network side equipment and ask It asks.

After network side equipment carries out the authentication for being directed to group to UE is received, and the authentication is passed in reception UE, notice UE authentication Pass through.Preferably, the configuration information of the group can also be notified to give reception UE in a manner of dedicated signaling.

Receive special wireless temporary identifier (such as B-RNTI or SPS-RNTI) decoding that UE can be obtained with oneself Descending scheduling signaling simultaneously parses, and receives UE and receives and be decoded, if receiving and decoding correct, then it is assumed that it is wide to receive D2D Broadcast communication data.

Preferably, network side equipment can be judged at a distance from group according to UE, selection distance is less than given threshold Group, and UE is authenticated.

If receiving the configuration information for the group, scheduling can be monitored, be solved according to the configuration information of group by receiving UE The operation such as code.

Preferably, the UE can be wished that the requirement for receiving D2D broadcast data refers to for the reception UE for being in connected state Show and network side eNB, such as 1bit is given to report, shows to wish to receive D2D broadcast data.Network side equipment can be according to locating for the UE Position, carry out calculating distance as the position of UE sent with request in cell, will meet centainly at a distance from reception UE ID in the affiliated group information of transmission UE and the group of transmission UE of condition (such as distance is less than some thresholding and regards as approaching) Informing reception UE(, the authentication is passed on condition that the UE is for the group), reception UE in this way is receiving public D2D broadcast scheduling When signaling, it is only necessary to carry out attempting to receive the decode i.e. in the group and the corresponding scheduling resource of ID of the transmission UE close with oneself Can, reduce the processing complexity of UE.Another way, network side equipment is informed by dedicated signaling receives the close group of UE Information, without in this way for receiving for UE, for the scheduling of all transmissions of the group, all may be used specific to some UE in group To go to receive.

Example three:

Each transmission UE uses one or more dedicated RNTI, i.e., each corresponding one or more special nothings of user equipment Line temporary identifier.

When transmission UE each in cell uses one or more dedicated RNTI, for sending for UE, led to by eNB Dedicated signaling is crossed to inform UE, for the configuration of the UE, such as sends (such as the D- of special wireless temporary identifier corresponding to UE RNTI(D2D RNTI) and/or SPS-RNTI).

For receiving for UE, the special wireless temporary identifier that can be obtained with oneself (such as D-RNTI(D2D RNTI parsing data) and/or SPS-RNTI) are carried out, successfully decoded, it is believed that complete D2D broadcast reception.

Specific step is as follows:

Preferably, can be with wide for information, network side equipments such as the special wireless temporary identifiers that has dispensed The mode for broadcasting message notifies to update the broadcasted content to other UE in cell, and in information changing.

Between three of the above embodiment and exclusiveness is not present, can coexist in any combination.Such as part UE is taken The distribution of dedicated D-RNTI takes G-RNTI to distribute part UE, and remaining all UE take B-RNTI scheduling etc..

It is applicable for above-described embodiment the present invention also provides a kind of solution across under eNB.

In the above-described embodiments, either broadcast, dedicated signaling configuration or PDCCH scheduling, is all in a cell It executes.The embodiment of the present invention also provides a kind of configuration and dispatching party for close UE that is resident or being connected to other cells Case.

The first string: the case where being covered for overlapping.

When there is the covering of multiple carrier waves on a certain region, such as the various scenes of CA, multiple carrier waves are had in deployment to be covered Cover identical region.At this point, being resident as far as possible in order to guarantee the reception UE of D2D communication and send UE and being connected to identical frequency point i.e. In cell, the method that can be taken is:

Network side equipment polymerize reception ability according to the carrier wave of user equipment, selects serving cell for user equipment, so that The serving cell and D2D frequency point of user equipment are located at user equipment can be simultaneously within received frequency point ranges；And/or

Network side equipment broadcasts D2D frequency point, so as to need to send the user equipment of D2D data and need to receive D2D data User equipment select D2D frequency point.

By the above-mentioned means, following effect can be reached:

1, transmitting terminal and receiving end should all be maintained at D2D frequency point with corresponding communication capacity；

2, for the UE in IDLE, network side equipment does not control its frequency point, so network side equipment is to D2D's Frequency point is broadcasted, to help UE to reside in D2D frequency point；

3, for the UE in connected state, because the operation of the changing cells such as switching is that network side equipment is controlled, Therefore network side equipment needs to consider that new cell is able to satisfy user equipment on D2D frequency point simultaneously when switching over judgement The requirement of communication is kept, if it is then switching over, if not all right, there are many processing modes.For example oneself is reported by UE Tendency be limited holding unicast or preferentially keep D2D such as when that cannot keep simultaneously, then network side equipment according to The tendency of UE takes different measures.Specifically, if UE selection D2D is preferential, network side equipment releases the unicast of UE It puts, to guarantee that D2D communication can carry out, if UE selection unicast is preferential, UE can be switched to and not keep the small of D2D communication Area gets on, the preferential transmission for guaranteeing unicast.

Specifically, one or more frequency point is selected in multiple frequency points, as D2D frequency point (the specifically frequency as D2D Point can provide in the protocol；It can also be determined by network side equipment；Network side equipment is notified after can also being determined by high level), And D2D frequency point information is broadcasted in the SIB for the cell that related peripheral is covered with covering or continuously.For being desired with D2D industry D2D frequency point can be reported as the highest priority of gravity treatment or connected state and oneself be desired with D2D business (example by the UE of business Such as 1bit) or specifically interested D2D frequency point information to network side equipment, grasp in subsequent changing district by such network side equipment It is contemplated that being maintained on the D2D frequency point to the UE in work.

For example, under the scene of CA Small Cell, select a frequency point of the Macro Cell extensively covered as D2D frequency point broadcasts the frequency point information in the SIB of all adjacent cells, for being desired with the UE of D2D business, needs as far as possible Gravity treatment is switched to the cell, so that UE can monitor relevant configuration and scheduling under the cell, completes the normal behaviour of D2D Make.

Second scheme: the case where continuously being covered for same frequency.

The information of the cell of self-management is notified adjacent cell by network side equipment, so that the user equipment in adjacent cell carries out D2D across cell is communicated, and the information of adjacent cell is broadcasted after the information for receiving adjacent cell.

Specifically, working as some region, under the continuous coverage condition of frequency, which is D2D traffic frequencies.Each has The cell of D2D business needs to send the position of UE according to the D2D range communicated and D2D, to the D2D UE of adjacent cell whether Judged it is possible that receiving D2D transmission.

Whether is possible to the D2D UE of adjacent cell, this cell needs to carry out prior notice the case where receiving D2D transmission Adjacent cell (such as being notified by X2 interface) informs the relevant configuration information of adjacent cell and scheduling information.

For adjacent cell, then relevant configuration information and scheduling information can also be sent in cell, in favor of The UE at edge can receive across cell carry out D2D transmission.

For receiving for UE, the D2D content of this cell and other cell is received, process is the same.It is all according to tune Degree goes to attempt to decode to corresponding resource location, and decoding is correct, is considered as completing to receive.

For edge UE, such as one UE of network side equipment dispatching will send data, not only will be in this Cell Broadcast CB Scheduling, allows the UE of this cell to receive, it is also desirable to neighbouring cell is told, in adjacent cell also broadcast scheduling, so that adjacent cell UE It can receive the transmission of network side equipment edge UE.
