Second subscriber equipment, according to transmission D2D messaging parameter, the resource that resource scheduling information is corresponding receives D2D data.

Wherein, D2D messaging parameter include but not limited to following in part or all of:

Modulating-coding form, transmitted power.

Such as network equipment can need the size, type etc. of the D2D data sent to determine D2D messaging parameter according to first user equipment.

Such as transmitted power is mainly by the impact of D2D communication range, for the UE that the D2D communication range of request is larger, need to distribute larger transmitted power, otherwise the UE that the D2D communication range for request is less, needs to distribute less transmitted power, transmitted power is simultaneously also relevant with the ability of UE, can not exceed UE ability, and transmitted power also needs the disturbed condition considering overall network, or the disturbed condition etc. around UE.In the situation that interference ratio is more serious, transmitted power should be lower, and when disturbing light, transmitted power can suitably raise.

For modulating-coding form, need to consider that the resource can distributed to this D2D user have much, need the size of data sent, and the factor such as received signal to noise ratio, communication range of expection, comprehensively determine, the concrete algorithm of different realizations is also different.

In force, the network equipment of the embodiment of the present invention can adopt dynamic or semi-static mode, is the first user Equipments Setting D2D communication resource.

Dynamic dispatching is, can dispatch according to the sequential relationship of dynamic dispatching and dynamic dispatching.Such as dynamic dispatching can reporting according to UE, according to the traffic performance of outgoing data amount size and resource occupation and UE, signing rate behavior etc., use dispatching algorithm, Dynamic Resource Allocation for Multimedia is carried out to UE, then uses PDCCH mode that dynamic resource is sent to UE.

Concrete, network equipment can moment of occurring of pre-configured D2D broadcast communication, such as cycle and pattern, can notify all subscriber equipmenies by SIB system information.Such subscriber equipment only needs to carry out monitoring and resolution scheduling signaling in particular moment.Wherein, dispatch can be dispatched multiple subframe.

In order to save subscriber equipment power consumption and process complexity, semi-persistent scheduling can also be adopted.Semi-persistent scheduling has various ways.

One, network equipment broadcast allocation semi-persistent resource complete or collected works, corresponding carve information and resource identification, and pass through resource identification corresponding to user equipment specific signaling subscriber equipment.

Two, network equipment passes through the D2D communication resource corresponding to user equipment specific signaling subscriber equipment, and broadcast the D2D communication resource of all special user equipments, wherein special user equipment does not need when sending D2D data to dock the subscriber equipment that terminating subscriber equipment carries out authentication.

In aforesaid way, semi-persistent resource is distributed by dedicated signaling, namely subscriber equipment has known that what the resource of oneself has been, resource scheduling information serves as the switch of this semi-persistent resource, such as when UE has data, network equipment can use PDCCH signaling to carry the mark of " start or activate ", inform subscriber equipment can bring into use before distribute semi-persistent resource, until network side judges that this resource UE no longer needs to use, the mark of " stopping or deexcitation " can be used equally, inform that UE is follow-up no longer to this semi-persistent resource user.

That is, after semi-persistent resource distributes, resource scheduling information is only for activating/not activation notification, and when the semi-persistent resource of distributing before namely controlling can be used, and when can not use.

Enumerate several semi-static example below:

1, resource has numbering:

The semi-persistent resource that pre-configured D2D broadcast communication uses, network equipment can notify all subscriber equipmenies by SIB system information, and these resources is numbered.When reality uses, which semi-persistent resource, according to the D2D of user request or service request (be layer three process or more high level process), with dedicated signaling form notice UE, is distributed to this UE by network side, directly can notify the numbering of resource, also can notify the specifying information of resource.

2, resource is without numbering:

The semi-persistent resource that pre-configured D2D broadcast communication uses, network equipment can notify all subscriber equipmenies by SIB system information.

To the transmission subscriber equipment of each request resource, network equipment can according to traffic performance, distribute this subscriber equipment exclusive semi-persistent resource to the transmission subscriber equipment needed in dedicated signaling mode, this semi-persistent resource needs the subset belonging to the semi-persistent resource set notified in SIB system information, after distribution, network equipment is again with special wireless temporary identifier scrambling resource scheduling information, notifying user equipment activates operations such as (or deexcitations) to special semi-persistent resource, instructs the resource sending subscriber equipment to use.

For reception subscriber equipment, the semi-persistent resource set that network equipment can directly be broadcasted in SIB message.Receive in each resource of subscriber equipment in semi-persistent resource set and all carry out the trial of reception data.Further, for the reception subscriber equipment being in connected state, network equipment can according to the Distance Judgment receiving subscriber equipment and each transmission subscriber equipment, the resource used apart near transmission subscriber equipment is informed reception subscriber equipment with dedicated signaling, such reception subscriber equipment can have object to receive, and avoids the search in wholly-owned source range.

Row give some instances and to be described in detail to the solution of the present invention below.

Following examples illustrate distribution to D2D broadcast communication resource and use procedure with LTE system,

Other system and LTE system process similar, do not repeat them here.

Example one:

In community, common source schedule information carries out scrambling, the one or more special wireless temporary identifier that all subscriber equipmenies in Ji Yige community are corresponding identical.

Wherein, the resource scheduling information shared in community carries out scrambling, can take system default, such as, specify in standard agreement; Can also by network equipment by broadcast notifying user equipment.

In force, the present embodiment carries out the special wireless temporary identifier of scrambling can be for the B-RNTI of D2D Dynamic Broadcast Transmission scheduling and/or the SPS-RNTI for D2D semi-static broadcast transmitting and scheduling.

When UE wishes that peripherad UE sends D2D broadcast communication data, need the data volume size reporting request to network and/or report oneself needs to transmit.Network carries out the scheduling of the D2D communication resource to this UE.After UE receives this resource, allocated resource sends D2D broadcast data;

For reception UE, anyly have the ability and wish to receive the UE of D2D broadcast communication data, the resource scheduling information obtained in advance can be utilized, dispatch in PDCCH is resolved, if be decoded to correct D2D broadcast scheduling, then attempt receiving in the resource of scheduling, if received, then complete the reception of a D2D broadcast data.

Concrete steps are as follows:

Step 0: the special wireless temporary identifier of this community, with the form of SIB broadcast or the form adopting standard default, is informed UE by network side.Optionally, dynamic or semi-static mode can also be adopted, for UE configures the D2D communication resource.

In force, if network side does not inform the semi-static communication resource of UE D2D, network side can only use dynamic dispatching, divides resource to UE namely at every turn dynamically, and resource location needs all to send out at every turn, and expense is larger.Pre-configured words (i.e. semi-static configuration), resource is disposable pre-configuredly can be periodic to UE(), UE uses voluntarily, and saving signaling, but has requirement to the business model (Pattern) of UE, must have some cycles.

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

Step 1: send UE(and refer to there is D2D broadcast communications capability and the UE wishing transmission D2D broadcast communication data), before sending D2D broadcast communication data, need to enter connected state, the request of D2D transmission is carried out (preferably to network side transmission, the communication type of request can be carried in this request, carry out the information etc. of authentication to core net).

For network equipment, need the information such as communication type according to request, carry out D2D broadcast communication admission processing, and use dedicated signaling process to this UE, for this UE distributes a special ID, this ID is in order to distinguish UE when dispatching.Alternatively, network equipment can configure some dedicated periodic resources, similar semi-static scheduling resources configuration.

If dynamic-configuration resource, then UE listens scheduling at every turn, then uses resource transmission.If preassignment, then UE according to the pre-configured cycle, can use according to established rule.

For step 0 for the semi-static communication resource of UE configuration D2D is that unification is configured to the semi-static communication resource set of D2D, namely to the configuration that any UE can both receive, particularly for receiving terminal UE.The intersection of the semi-static configuration of all transmitting terminal UE is broadcasted by such as network equipment, and such receiving terminal UE can attempt decoding in all positions.

Step 1 is be configured transmitting terminal UE individuality for UE configures the D2D communication resource, and that is transmitting terminal UE needs which the resource D2D communication knowing oneself as actually.

Step 2: send the confirmation signaling that UE receives network equipment, such as, after reception D2D configuration (configuration) signaling etc., when needing there being D2D broadcast data to send, carrying out resource scheduling request to network side and/or reporting oneself outgoing data amount size.

If only carry out data volume to report and imply dispatch request.In force, more comprehensively, and the benefit of dispatch request is simple to data volume reporting information.

Step 3: network equipment, when receiving resource scheduling request and/or outgoing data amount size, determines the D2D communication resource distributed to this UE, can be dynamic Resourse Distribute, also the semi-static scheduling resources configured before can be activated.

Such as know outgoing data amount size, will more be conducive to the efficiency of dispatching, when the traffic performance according to UE, take be dynamic dispatching configuration time, then can according to the actual data volume size reported, in conjunction with resource and dispatching algorithm etc., determine how dynamic allocation of resources;

Such as not knowing outgoing data amount size, general corresponding semi-persistent scheduling, may be that the business of UE has certain transmission rate rule, configure semi-persistent resource before, once receive dispatch request, namely mean that the data burst of UE arrives, then activate semi-persistent resource.

Step 4: it (is such as that dynamic dispatching is then with the scrambling of B-RNTI form that the resource scheduling information distributing to transmission UE is carried out scrambling with special wireless temporary identifier by network equipment, that semi-persistent scheduling is then with the scrambling of SPS-RNTI form), and send with the form of descending dispatch.Preferably, inside dispatch, display carry the special I D that this transmission UE distributes when step 1, be distribute to the transmission UE specified to indicate this resource.

Preferably, network equipment can also by transmission parameter configuration to UE, such as modulating-coding form, transmitting power etc.

Wherein, modulating-coding form etc., can according to the communication distance of UE, overall network disturbed condition, and even the measurement of UE reports situation etc., carries out comprehensive assessment, and which kind of modulating-coding form final decision adopts.

Step 5: send UE and to decode descending scheduling signaling resolving with special wireless temporary identifier (such as B-RNTI or SPS-RNTI), if find that there is one's own special D2D broadcast communication scheduling, (such as judging that whether the ID that carries in dispatch is oneself special I D), with the transmission parameter of specifying in the resource of then specifying at network equipment, such as modulating-coding form, transmitting power etc., send D2D broadcast data.

If network equipment does not configure transmission parameter, then UE self determines to send parameter.

Step 6: receive UE(and refer to have the UE of D2D communication or D2D receiving function and wish to receive D2D broadcast data), on all scheduling resource positions, the special wireless temporary identifier (such as B-RNTI or SPS-RNTI) that can obtain with oneself is decoded descending scheduling signaling resolving, if resolve correct, then receive in resource that UE indicates at dispatch and carry out receiving and D2D broadcast communication data of decoding, if receive and decode correct, then think and receive D2D broadcast communication data.

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

Like this, receive UE only according to transmission parameter, to receive and decode.If do not configure transmission parameter, then receiving UE needs blind check, attempts all possible situation of traversal.

Preferably, for the reception UE being in connected state, this UE can be wished that the requirement receiving D2D broadcast data is indicated to network equipment, such as 1bit reports, show to wish to receive D2D broadcast data, then network equipment can position residing for this UE, calculating distance is carried out with the position of asking in community as the UE sent, privately owned ID distance with this reception UE being met the transmission UE of certain condition (such as distance is less than certain thresholding and regards as close) informs this reception UE, such reception UE is when receiving public D2D broadcast scheduling signaling, only need to carry out trial on the scheduling resource that the ID with oneself close transmission UE is corresponding to receive the decode, reduce the process complexity of UE.

Preferably, network equipment, according to receiving UE and the distance sending UE, is the second user device configuration received power scope.

Example two:

One group of UE uses one or more special RNTI.Namely the one or more special wireless temporary identifier that all first user equipment in a group of user equipments are corresponding identical.

When in community, one group of UE uses the scheduling of one or more special RNTI pointer to D2D broadcast communication, inform by dedicated signaling the UE group that UE adds by eNB, and for the configuration (such as organizing mark) of this group, the special wireless temporary identifier (such as G-RNTI(Group RNTI) corresponding to group and/or SPS-RNTI).Preferably, the mark of this UE in this group can also be informed, to distinguish different UEs when dispatching.

For reception UE, restriction (Restricted) can be divided into add and open (Open) and add, the former needs network to carry out authentication to the reception UE added, and only has the successful UE of authentication just can inform group configuration, generally can use dedicated signaling process; If the adding of Open, then do not limit UE, UE can be received as long as neighbouring can receive, the configuration of all groups now can be broadcasted by the mode of SIB signaling, UE simultaneously for connected state also can be far and near according to position each other, auxiliary this reception UE informs it is near which group further, with the schedule information and the packet that make UE resolve these groups specially.

When UE wishes that peripherad UE sends D2D broadcast communication data, first need to report request to network, by network equipment according to the Distance Judgment between UE, whether have and set up, and from the close group of this UE, if had, then this UE is incorporated to this group, and notifies ID in the information of this group of UE and the special group of UE in dedicated signaling mode, the follow-up scheduling by network equipment, this UE being carried out to the D2D communication resource, after receiving this resource, UE sends D2D broadcast data in allocated resource.

For reception UE, anyly have the ability and wish to receive the UE of D2D broadcast communication data, public G-RNTI or SPS-RNTI obtained in advance can be utilized, or privately owned G-RNTI, SPS-RNTI etc., dispatch in PDCCH is resolved, if be decoded to correct D2D broadcast scheduling, then carry out trial on the resource and receive, if receive and decode correct, then complete the reception of a D2D broadcast data.

For Open group Adding Way, concrete steps are as follows:

Step 1: send UE(and refer to there is D2D broadcast communications capability and the UE wishing transmission D2D broadcast communication data), before sending D2D broadcast communication data, need to enter connected state, D2D transmission request is carried out (preferably to network side, the communication type of request can be carried in this request, comprise and carry out authentication etc. to core net).

For network equipment, need according to information such as the communication types of asking, D2D broadcast communication admission processing is carried out to this UE, and whether had the group set up according to around the position judgment UE of UE, if had, then directly put this UE under this group and inform the configuration of this group, if do not had, set up a new group, use dedicated signaling afterwards, ID special in the group configuration information of this UE and group is notified UE, wherein group configuration can comprise group ID, for distinguishing the special wireless temporary identifier of different group when the special wireless temporary identifier of configuration group, in the group of this UE, ID is in order to distinguish UE when dispatching.Alternatively, network equipment can configure some dedicated periodic resources, similar semi-static scheduling resources configuration.

Such as such as organize 1 corresponding RNTI1, group 2 corresponding RNTI2 etc.In addition, group configuration can also comprise the attribute information of group, and such as open group or restricted group, even specific people, such as organize 1 corresponding public security officer, group 2 corresponding traffic police personnel etc.

For the group information corresponding to the group built up, such as, organize mark, the information such as special wireless temporary identifier, network equipment can inform other UE in community in the mode of broadcast, and when organizing variation, upgrades this broadcasted content.

Step 6: receive UE(and refer to have the UE of D2D communication or D2D receiving function and wish to receive D2D broadcast data), on all scheduling resource positions, the special wireless temporary identifier (such as B-RNTI or SPS-RNTI) that can obtain with oneself is decoded descending scheduling signaling resolving, receive UE receive and decode, if receive and decode correct, then think and receive D2D broadcast communication data.

Preferably, can be wished that the requirement receiving D2D broadcast data is indicated to network side eNB for the reception UE being in connected state, this UE, such as 1bit reports, and shows to wish to receive D2D broadcast data.Network equipment can position residing for this UE, calculating distance is carried out with the position of asking in community as the UE sent, in affiliated group information distance with this reception UE being met the transmission UE of certain condition (such as distance is less than certain thresholding and regards as close) and the group sending UE, ID informs this reception UE, such reception UE is when receiving public D2D broadcast scheduling signaling, only need to carry out trial on the scheduling resource that the group and ID of following oneself close transmission UE are corresponding to receive the decode, reduce the process complexity of UE.Another kind of mode, network equipment informs the information receiving the close group of UE by dedicated signaling, and not specific to certain UE in group, like this for reception UE, for the scheduling of all transmissions of this group, can go to receive.

For Restricted group Adding Way, concrete steps are as follows:

For network equipment, need according to information such as the communication types of asking, D2D broadcast communication admission processing is carried out to this UE, and whether had the group set up according to around the position judgment UE of UE, if had, then for the group of surrounding, authentication process is carried out to this UE, put this UE under this group after meeting at UE the condition adding this group and inform the configuration of this group, if do not had, set up a new group, use dedicated signaling afterwards, ID special in the group configuration information of this UE and group is notified UE, wherein group configuration can comprise group ID, for distinguishing the special wireless temporary identifier of different group when the special wireless temporary identifier of configuration group, in the group of this UE, ID is in order to distinguish UE when dispatching.Alternatively, network equipment can configure some dedicated periodic resources, similar semi-static scheduling resources configuration.

Preferably, network equipment can judge according to the distance of UE and group, and chosen distance is less than the group of setting threshold, and carries out authentication to UE; If, newly do not set up a group.

Step 6: receive UE and refer to have the UE of D2D communication or D2D receiving function and wish to receive D2D broadcast data), when hope receives the information of certain Restricted Group, need first to carry out authentication for group and request to network equipment.

Network equipment carries out the authentication for group to reception UE, and in reception UE authentication by afterwards, notice UE authentication is passed through.Preferably, can also notify that the configuration information of this group is to receiving UE in dedicated signaling mode.

Receive the UE special wireless temporary identifier (such as B-RNTI or SPS-RNTI) that can obtain with oneself to decode descending scheduling signaling resolving, receive UE and receive and decode, if receive and decode correctly, then think and receive D2D broadcast communication data.

Preferably, network equipment can judge according to the distance of UE and group, and chosen distance is less than the group of setting threshold, and carries out authentication to UE.

If receive the configuration information for this group, receiving UE according to the configuration information of group, can monitor scheduling, carries out decoding etc. operation.

Preferably, can be wished that the requirement receiving D2D broadcast data is indicated to network side eNB for the reception UE being in connected state, this UE, such as 1bit reports, and shows to wish to receive D2D broadcast data.Network equipment can position residing for this UE, calculating distance is carried out with the position of asking in community as the UE sent, in affiliated group information distance with this reception UE being met the transmission UE of certain condition (such as distance is less than certain thresholding and regards as close) and the group sending UE, ID informs that this reception UE(prerequisite is that this UE passes through for the authentication of this group), such reception UE is when receiving public D2D broadcast scheduling signaling, only need to carry out trial on the scheduling resource that the group and ID of following oneself close transmission UE are corresponding to receive the decode, reduce the process complexity of UE.Another kind of mode, network equipment informs the information receiving the close group of UE by dedicated signaling, and not specific to certain UE in group, like this for reception UE, for the scheduling of all transmissions of this group, can go to receive.

Example three:

Each transmission UE uses one or more special RNTI, i.e. the corresponding one or more special wireless temporary identifier of each subscriber equipment.

Concrete steps are as follows:

Preferably, for information such as the special wireless temporary identifiers dispensed, network equipment can inform other UE in community in the mode of broadcast, and when information changing, upgrades this broadcasted content.

There is not exclusiveness between above three kinds of execution modes, can combination in any coexist.Such as part UE is taked to the distribution of special D-RNTI, take G-RNTI to distribute to part UE, remain all UE and take B-RNTI to dispatch.

Present invention also offers a kind of across the solution under eNB, all applicable for above-described embodiment.

In the above-described embodiments, no matter be broadcast, dedicated signaling configuration, or PDCCH scheduling, all perform in a community.The embodiment of the present invention also provides a kind of for resident or be connected to the configuration of close UE and the scheduling scheme of other community.

The first string: the situation that overlap is covered.

When a certain region there being multiple carrier wave cover, the various scenes of such as CA, deployment have multiple carrier wave and cover identical region.Now, try one's best resident to ensure the reception UE that D2D communicates and sending UE and be connected on identical frequency and community, the method that can take is:

Network equipment, according to the carrier aggregation receiving ability of subscriber equipment, is that Serving cell selected by subscriber equipment, is positioned within the frequency point ranges that subscriber equipment receives simultaneously to enable the Serving cell of subscriber equipment and D2D frequency; And/or

Network equipment broadcast D2D frequency, to make the subscriber equipment needing to send D2D data and the subscriber equipment selection D2D frequency needing to receive D2D data.

By the way, following effect can be reached:

1, transmitting terminal and receiving terminal all should remain on D2D frequency and have corresponding communication capacity;

2, for the UE being in IDLE, network equipment does not control its frequency, so the frequency of network equipment to D2D is broadcasted, resides in D2D frequency to help UE;

3, for the UE being in connected state, because the changing cells operations such as switching are that network equipment controls, therefore network equipment is when carrying out switch decision, need consider new community can meet subscriber equipment keep on D2D frequency simultaneously communicate requirement, if passable, then switch, if not all right, then have multiple processing mode.Such as reported the tendency of oneself by UE, such as, when can not keep simultaneously, be limited maintenance clean culture or preferentially keep D2D, then network equipment takes different measures according to the tendency of UE.Particularly, if UE selects D2D preferential, then the clean culture of UE discharges by network equipment, to ensure that D2D communication can be carried out, if UE selects clean culture preferential, then UE can be switched to the community not keeping D2D to communicate and get on, the preferential transmission ensureing clean culture.

Concrete, in multiple frequency, select one or more frequency, as D2D frequency, (frequency specifically as D2D can specify in the protocol; Also can be determined by network equipment; Rear informing network side apparatus can also be determined by high level), and D2D frequency point information is broadcasted in the SIB of the same community covered or cover continuously of related peripheral.Hope is carried out to the UE of D2D business, can using the limit priority of D2D frequency as gravity treatment, or connected state reports oneself wishes to carry out D2D business (such as 1bit) or concrete interested D2D frequency point information to network equipment, and such network equipment can be considered to remain on this D2D frequency this UE in the operation of follow-up changing district.

Such as, under the scene of CA or Small Cell, select a frequency of the wide Macro Cell covered as D2D frequency, all this frequency point information is broadcasted in the SIB of all adjacent cells, hope is carried out to the UE of D2D business, need as far as possible gravity treatment or be switched to this community, to make UE can monitor relevant configuration under this community and scheduling, completing the normal running of D2D.

Second scheme: for the situation with covering continuously frequently.

Network equipment, by the message notice adjacent cell of the community of self-management, carries out to make the subscriber equipment in adjacent cell communicating across the D2D of community, and broadcast the information of adjacent cell after receiving the information of adjacent cell.

Concrete, when some regions, with under frequency continuously coverage condition, this frequency is D2D traffic frequencies.Each has the community of D2D business, needs the scope according to D2D communication, and D2D sends the position of UE, whether likely receives this D2D transmission judge the D2D UE of adjacent cell.

Whether the D2D UE of adjacent cell is likely received to the situation of this D2D transmission, this community needs to carry out prior notice adjacent cell (such as being notified by X2 interface), informs the configuration information that adjacent cell is relevant and schedule information.

For adjacent cell, then can send in relevant configuration information and schedule information Ye community, the UE being beneficial to edge can receive and carry out D2D transmission across community.

For reception UE, receive the D2D content of this community and other community, process is the same.Be all according to scheduling, go to attempt decoding to corresponding resource location, decoding is correct, has just thought reception.

For edge UE, a such as network equipment dispatching UE will send data, not only will in this Discontinuous Reception Mechanism, the UE of this community is allowed to receive, also need to tell contiguous community, in adjacent cell also broadcast scheduling, make adjacent cell UE also can receive the transmission of network equipment edge UE.
