Embodiment

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

Shown in Figure 3, the resource allocation method in a kind of D2D communication that the embodiment of the present invention provides, comprises the following steps:

Step 31, network side, according to the traffic performance of D2D communication and the current behaviour in service of resources in network, are the D2D resource of the D2D terminal configuration in the D2D communication set of having set up for D2D communication;

Concrete, in this D2D communication set, comprising at least two D2D terminals of having set up D2D communication link, any two the D2D terminals in this D2D communication set all can be carried out D2D communication.

Step 32, network side send to each the D2D terminal in this D2D communication set by the configuration information of the D2D resource having configured;

Wherein, each D2D terminal in this D2D communication takies the D2D resource having configured, determined and notified to each D2D terminal, or the D2D terminal in this D2D communication set is determined by network side.

The embodiment of the present invention proposes the method that a kind of network side DuiD2D signal post is used resource to be configured, under the control of network, make can utilize more flexibly D2D resource between each D2D terminal in D2D communication set, thereby reduced the interference between D2D communication and legacy cellular communication, improve the throughput of entire system, also improved user's experience.

Preferably, network side employing Radio Resource control (Radio Resource Control, RRC) signaling is the D2D resource that this D2D communication set is configured for D2D communication.

Preferably, network side is that the D2D resource of this D2D communication set configuration is communicated by letter for D2D in setting duration or before deexcitation, and network side adopts the semi-static D2D resource that this D2D communication set is configured for D2D communication that is configured to;

Further, network side, when carrying out semi-static configuration, can also carry the indication information of the effective time range that is used to indicate this resource distribution;

Concrete, if current time not in the effective time range of this resource distribution, this resource distribution was lost efficacy, or after receiving the deexcitation order for this resource distribution that network side sends, this resource distribution was lost efficacy.

In force, in step 31, if determining between two D2D UE or one group of D2D UE, network side set up D2D communication link,: network side, according to the traffic performance of D2D communication and the current behaviour in service of resources in network, is the D2D resource of the D2D terminal configuration in the D2D communication set of having set up for D2D communication.

For example, the business of the D2D communication of this D2D communication set has typical assurance bit rate (Guaranteed Bit Rate, GBR) traffic performance, such as video conversation business etc., have specific transmission rate request, this network side determines to use for D2D communication for the D2D terminal configuration D2D resource in this D2D communication set;

And for example, the business of the D2D communication of this D2D communication set is that data are downloaded class, file transfer protocol (FTP) (File Transport Protocol for example, FTP) etc., although there is no GBR requirement, but in whole transmission cycle, message transmission rate requires more fixing, for example download the file of 20M, this network side can be according to the current service condition of resource scheduling algorithm, resources in network of setting and the signing user rate requirements of D2D UE in this D2D communication set, for this D2D communication set, divide the D2D resource that is used in D2D communication, for transfer of data, use;

For another example, when Internet resources looser, or current be configured to via the resource of the communication path of core net at the appointed time can BeiD2D signal post in scope multiplexing, for example this resource is by the semi-static UE who communicates via core network that distributes to, and between the traditional communication link of this UE communication path of core net (via) and D2D link, disturb less, the multiplexing rule that meets setting, this network side can carry out multiplexing to this part resource, for D2D communication, use at the appointed time, this part resource distribution to this D2D communication set, thereby save the control signal expense of network dynamic dispatching D2D resource,

For another example, when the control signal expense of network side (as eNB) takies larger, and the D2D communication service of this D2D communication set can be stood certain time time delay, this network side configures semi-static D2D resource also can to this D2D communication set, to save the expense of control signal.

Preferably, in step 31, network side is the semi-static D2D resource of D2D terminal configuration in the D2D communication set of having set up, and this D2D resource is communicated by letter for D2D in setting duration or before carrying out deexcitation.

In force, network side is that a kind of preferred configuration mode of D2D resource of D2D communication set configuration is as follows:

The resource pattern (pattern) of correspondence in frequency+running time-frequency resource particular location+time domain; Or,

Frequency+running time-frequency resource particular location+repetition period.

It should be noted that, network side can be this D2D communication set configuration D2D resource on same frequency, can on different frequent points, be also this D2D communication set configuration D2D resource; Network side is that the repetition period of the D2D resource of D2D communication set configuration can be all identical, also can part identical, can also be entirely not identical.

In force, a kind of preferred resources employment methods is, in step 31, network side is the configuration that this D2D communication set configures the multiple D2D resource for D2D communication, and the configuration information of the D2D resource of communicating by letter for D2D for all kinds of this D2D communication set configuration is all sent to each D2D terminal.

Preferably, the size of the D2D resource that configuration packet not of the same race contains has difference, if configuration not of the same race provides different transmission rates, to tackle the variation of data volume;

For example, network side can provide following two kinds of different configurations by RRC signaling:

The first configuration packet is containing Resource Block 1 and Resource Block 2, and the repetition period is T;

The second configuration only comprises Resource Block 2, and the repetition period is T.

In above-mentioned two kinds of configurations, it is more that the first configures shared resource, and the transmission rate that can provide is higher, and the second configuration is than the first configuration, and its shared resource is less, and the transmission rate that can provide is less.

And for example, network side can provide following two kinds of different configurations by RRC signaling:

The first configuration packet is containing Resource Block 1, and the repetition period is T;

The second configuration packet is containing Resource Block 2, and the repetition period is 2T.

It should be noted that the configuration of the multiple D2D resource of this D2D communication set, in the same moment, can only be used the configuration of a kind of D2D resource wherein.

If being D2D communication set, network side configured the configuration of the multiple D2D resource for D2D communication: can the make an appointment configuration of the D2D resource of use when initial of network side and D2D communication set; Or network side is indicated the current configuration in the D2D of state of activation resource of this D2D communication set.

Concrete, network side can be in advance arranges with the D2D terminal of D2D communication set the configuration of using when initial; For example, network side sends the configuration of 5 kinds of D2D resources to each D2D terminal of this D2D communication set by RRC signaling, network side and the D2D terminal of D2D communication set are made an appointment and are used the first resource distribution to carry out D2D when initial to communicate by letter, and each D2D terminal is all used the first resource distribution when initial;

Network side can also, when the configuration of all D2D resources that is sent as its configuration to this D2D communication set, be indicated the current configuration in the D2D of state of activation resource of D2D terminal of this D2D communication set; For example, this network side sends the configuration of 5 kinds of D2D resources to this D2D communication set by RRC signaling, and all uses the configuration of the first D2D resource to carry out D2D communication while indicating the D2D terminal initial of this D2D communication set by this RRC signaling;

Network side can also be by RRC signaling after this D2D communication set be sent as all resource distributions of its configuration, by L2/L1 signaling, indicate again the current configuration in the D2D of state of activation resource of D2D terminal of this D2D communication set, so that each D2D terminal is current, use the configuration of the D2D resource that adopts state of activation to carry out D2D communication.

Preferably, L2(Layer2) signaling mainly refers to media access control (Media Access Control, MAC) signaling, specifically with the form of media access control layer control unit (MAC Control Element, MAC CE), carries; L1(Layer1) signaling mainly refers to physical layer signaling, specifically with the form of Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH), carries.

In force, network side and D2D communication set can arrange to adopt the form of numbering to identify the configuration of multiple D2D resource, as number the configuration of 0 expression the first D2D resource, numbering 1 represents the configuration of the second D2D resource, the like, like this, network side, when the current configuration in the D2D of state of activation resource of D2D terminal of this D2D communication set of indication, only needs to carry numbering corresponding to this resource distribution.

Further, be sent as the configuration of all D2D resources of its configuration to this D2D communication set at network side after, this network side can also suspend the configuration of using any D2D resource by each D2D terminal in this D2D communication set of L2/L1 signaling, waits for the dynamic dispatching of this network side to resource distribution.

In force, if network side has only configured a kind of configuration of the D2D resource for D2D communication for this D2D communication set,: this network side can be first this D2D communication set configuration D2D resource by RRC signaling, then is sent and activate the indication of this resource distribution or the indication of this configuration of deexcitation to each the D2D terminal in this D2D communication set by L2/L1 signaling.

In force, if network side determines that the traffic performance of the D2D communication of this D2D communication set changes (as increased or reduced a D2D communication service on D2D link) or the current behaviour in service of resources in network changes, for the requirement of applicable current D2D communication service, the method also comprises:

Network side is that the D2D terminal in this D2D communication set reconfigures the D2D resource for D2D communication; And

Network side sends to each the D2D terminal in this D2D communication set by reconfiguration information, and indicates coming into force constantly of reconfiguration information described in each D2D terminal.

Concrete, coming into force of reconfiguration information is generally as the criterion with the absolute moment constantly, and for example, the moment of coming into force of this reconfiguration information can be System Frame Number (System Frame Number, SFN);

When network side can send this reconfiguration information in each the D2D terminal in this D2D communication set, carry the indication information constantly that comes into force that is used to indicate this reconfiguration information, also, after can sending this reconfiguration information in each the D2D terminal in this D2D communication set, by L2/L1 signaling, to each D2D terminal, send the indication information constantly that comes into force that is used to indicate this reconfiguration information.

It should be noted that, in above-mentioned configuration and reconfiguration course, be all that signal deployment is carried out to each UE of its service respectively in the Serving cell of each D2D UE.If the Serving cell of the D2D UE in this D2D communication set belongs to same eNB, this eNB just can determine the distribution condition of D2D resource according to the resource scheduling algorithm of self inside; If the Serving cell of the D2D UE in this D2D communication set belongs to two or more eNB, in decision D2D resource, divide timing, between different e NB, need to carry out mutual and consult, the situation of distributing with unified resource and other relevant configuration are (as the identification information of main UE, feedback configuration, the information such as rule that take of setting).

Preferably, if the different e NB of the Serving cell of each D2D UE in this D2D communication set ownership is corresponding to same control node, in the process to the resource distribution of communicating by letter for D2D of this D2D communication set and other relevant configuration, can control node by this and carry out unified decision-making and management, respectively to service eNB transmission resource allocation information and other configuration information of each D2D UE, finally by each service eNB, resource allocation information is sent to corresponding D2D UE again.

In force, taking of the D2D resource that each the D2D terminal in this D2D communication set is this D2D communication set configuration to network side, comprises following two kinds of definite modes:

Mode A, by network side, determine that each D2D terminal in this D2D communication set is to the taking of the D2D resource of configuration, and notice is to each D2D terminal;

In force, mode A further comprises again following two kinds of modes:

Mode A1, for the D2D resource that is the configuration of this D2D communication set, the explicit indication of network side from as each D2D terminal appointment for sending the transmission resource of data, be specially:

Network side is when configuration D2D resource, for each D2D terminal is specified for sending the transmission resource of data; Network side sends to all D2D terminals in D2D communication set by the transmission resource from as each D2D terminal distribution;

Accordingly, for each the D2D terminal in D2D communication set, D2D terminal is after receiving the transmission resource of network side for each the D2D terminal appointment in this D2D communication set, in the transmission resource that is self appointment at this network side, send data, in the transmission resource at network side for other D2D terminal appointments except self in this D2D communication set, receive data.

Under which, network side is when determining to be configured for the D2D resource of D2D communication for this D2D communication set, can to the corresponding relation between D2D resource and each D2D UE, stipulate simultaneously, or be respectively each D2D UE and distribute special-purpose D2D resource, but this network side must send to all D2D UE in this D2D communication set by the information of the D2D resource of distributing for each D2D UE.

For example, suppose the D2D UE that comprises two built vertical D2D links in this D2D communication set, be UE1 and UE2, network side is that the D2D resource collection that this D2D communication set is distributed is (resource A, resource B), wherein, the repetition period T(of D2D resource is certain, the repetition period here can be also the form of more complicated, such as different resources has the different repetition periods, or different resources has different pattern, the radio frames that for example resource A is only odd number at SFN is effective, and the radio frames that resource B is only even number at SFN is effective), this network side can explicit indexed resource A (be that UE1 sends in the enterprising row data of resource A by UE1 use in configuration signal, UE2 carries out data receiver on resource A), similarly, this network side can explicit indexed resource B (be that UE2 sends in the enterprising row data of resource B by UE2 use in configuration signal, UE1 carries out data receiver on resource B),

And for example, suppose the D2D UE that comprises two built vertical D2D links in this D2D communication set, be UE1 and UE2, network side is that UE1 has distributed for the resource A of D2D communication and for UE2 and distributed the resource B communicating by letter for D2D, wherein, this resource A has repetition pattern or the repetition period T1 of appointment, this resource B has repetition pattern or the repetition period T2 of appointment, this network is in issuing the resource allocation signaling of UE1 and UE2, assignment information except the D2D resource that comprises this UE, the assignment information that also comprises the D2D resource of the other side UE, so that when this UE this network side for self distribution D2D resource on send data in, the other side UE can carry out data receiver in identical resource.

It should be noted that, above-mentioned two illustrate, the D2D communication set of only take comprises two D2D UE and describes as example, while comprising plural D2D UE in this D2D communication set, the assigning process that carries out D2D resource for each D2D UE is similar, this network side is each the D2D UE distribution D2D resource that need to carry out D2D communication in this D2D communication set, and the assignment information of the D2D resource of all D2D UE is sent to all D2D UE that relate in this D2D communication set.

The occupancy mode that mode A2, network side and this D2D communication set are made an appointment to D2D resource, or network side takies pattern (pattern) this resource occupation image is sent to each D2D terminal for this D2D communication set resource allocation, to indicate each D2D terminal to use D2D resource according to this resource occupation pattern;

Under which, the occupancy mode of D2D resource if network side and this D2D communication set have been made an appointment, this network side be this D2D communication set D2D terminal configuration after the D2D resource for D2D communication, the configuration information of this D2D resource is sent to each D2D terminal; Accordingly, each D2D terminal, after receiving the configuration information of this D2D resource, adopts predetermined in advance occupancy mode (as rotation is used), uses this D2D resource to communicate.

Under which, network side is specially for this D2D communication set resource allocation takies pattern:

Network side is after for D2D communication set configuration D2D resource, for this D2D communication set is configured for the resource occupation pattern that take of each D2D terminal of indication to D2D resource; Network side sends to each D2D terminal by this resource occupation pattern, and wherein, the resource occupation pattern of each D2D terminal Adoption Network side configuration is used D2D resource.

Preferably, network side can send to each D2D terminal by the configuration information of D2D resource and resource occupation pattern in same RRC signaling; Network side also can first send to the configuration information of D2D resource each D2D terminal, reinforms this resource occupation pattern of each D2D terminal.

Under which, when network side determines to configure D2D resource for the D2D UE in this D2D communication set, can each D2D UE in this D2D communication set be stipulated the rule that takies of D2D resource simultaneously, obtain resource occupation pattern corresponding to each D2D terminal.

For example, using the Resource Block in each subframe as a D2D resource, by all D2D UE, be used alternatingly each D2D resource and send data.And when carrying out D2D resource distribution, stipulate the use order of all D2D UE, as being numbered to each D2D UE, according to numbering this D2D resource that uses in order from small to large simultaneously.Take this D2D communication set, to comprise two D2D UE be example, suppose network side for this D2D communication set distributed subframe 3 with the resource in subframe 6 as the D2D resource of communicating by letter for D2D, this network side notifies the resource occupation pattern to each D2D terminal to be, be numbered 1 UE1 and use the D2D resource in subframe 3, be numbered 2 UE2 and use the D2D resource in subframe 6;

And for example, if the data volume that UE1 and UE2 need to send is asymmetric, network side has distributed subframe 3 for this D2D communication set, resource in subframe 6 and subframe 8 is as the D2D resource for D2D communication, in each radio frames, subframe 3 and subframe 6, subframe 8 comprises respectively one for the D2D resource of D2D communication, this network side notifies the resource occupation pattern to each D2D terminal to be, be numbered 1 UE1 and use the D2D resource in subframe 3 and subframe 6, be numbered 2 UE2 and use the D2D resource in subframe 8;

For another example, Resource Block in each subframe is divided into a plurality of D2D resources, if this D2D communication set comprises 4 D2D UE, network side for this D2D communication set distributed subframe 3 with the resource in subframe 6 as the D2D resource of communicating by letter for D2D, wherein the resource in subframe 3 is divided into 2 D2D resources, the resource of subframe 6 is also divided into 2 D2D resources, network side is that the resource occupation pattern of each D2DUE configuration in this D2D communication set can be, be numbered 1 UE1 and be numbered two D2D resources that 2 UE2 uses in order in subframe 3 according to setting and send data, be numbered 3 UE3 and be numbered two D2D resources that 4 UE4 uses in order in subframe 6 according to setting and send data.

Table 1 has provided the example of specific implementation form of the resource occupation pattern of network side configuration:

Table 1

It should be noted that, table 1 is for this resource occupation pattern is described, does not limit the specific implementation form of this resource occupation pattern, and this resource occupation pattern also can adopt other ways of realization

Under which, network side can be used to indicate for one of all D2D terminal configuration in this D2D communication set the resource occupation pattern of each D2D terminal to the situation that takies of D2D resource, also can be used to indicate the resource occupation pattern of this D2D terminal to the situation that takies of D2D resource for one of each D2D terminal configuration.

Mode B, the D2D terminal in D2D communication set are determined each D2D terminal taking the D2D resource having configured;

In force, mode B further comprises again following two kinds of implementations:

Mode B1, by the selected main D2D terminal of network side, by this main D2D terminal pins, to each the D2D terminal in this D2D communication set, this network side is dispatched for the D2D resource of this D2D communication set configuration, be specially:

Network side is from this D2D communication set, a selected D2D terminal is as main D2D terminal, and the identification information of selected main D2D terminal is notified to each the D2D terminal in this D2D communication set, wherein, this main D2D terminal for dispatching the D2D resource of this network side configuration in this D2D communication set.

Under which, when network side determines to be used for the D2D resource of D2D communication for the D2D terminal configuration in this D2D communication set, also can be a main D2D terminal of this D2D communication set configuration simultaneously, and each the D2D terminal in this D2D communication set of explicit indication, by this main D2D terminal, decided the scheduling of the D2D resource to having configured.

Provide a kind of preferred specific implementation under which below:

When the D2D UE of network side in giving D2D communication set configures D2D resource, configure main D2D UE simultaneously, and notify the identification information of all these the main D2D UE of D2D UE in this D2D communication set, so which D2D UE each the D2D UE in this D2D communication set can know, be the main D2D UE of network side configuration;

Accordingly, each the D2D UE in this D2D communication set receives after the D2D resource and indication of this network side configuration, determines the main D2D UE in this D2D communication set.Further, when the arbitrary D2D UE in this D2D communication set need to send data, this D2D UE sends resource request and/or reports data volume to be sent to main D2D UE; This main D2D UE is after the data volume to be sent that receives the resource request of other D2D UE transmissions and/or report, according to the scheduling rule of setting, D2D resource to network side configuration is distributed, for the D2D UE in this D2D communication set divides, be used in the transmission resource that sends data, and the distribution condition of D2D resource is sent to each D2D UE; D2D UE in this D2D communication set is according to the distribution condition of the D2D resource receiving, the transmission of the enterprising row data of transmission resource of distributing for self at this main D2D UE, receives the data of other D2D UE transmissions in the transmission resource of distributing for other D2D UE except self at this main D2D UE.

Further, main D2D UE, when the D2D resource of network side configuration is dispatched, also considers the data volume of all D2D UE in this D2D communication set and the information such as priority separately.

For example, main D2D UE carries out the scheduling of D2D resource from high to low according to the priority of each D2D UE in this D2D communication set, the D2D UE of the first schedules high priority of main D2D UE sends data, and the D2D UE of all high priorities is all sent, then schedules low priority UE sends data;

And for example, each priority D2D UE is all assigned a GBR(and ensures bit rate), when main D2DUE determines that the resource request of other D2D UE transmissions clashes, the D2DUE that first guarantees high priority reaches guarantee bit rate, remaining D2D resource guarantees the guarantee bit rate of the D2D UE of low priority, if also have remaining D2D resource, then distribute from high to low according to priority.

Preferably, network side can carry the identification information of selected main D2D terminal in the configuration signal (as RRC signaling) of D2D resource; Also can be this D2D communication set configuration D2D resource to passing through RRC signaling, then by the identification information of each this main D2D terminal of D2D terminal in this D2D communication set of L2/L1 signaling.

In force, for the ease of realizing, preferred, the D2D terminal of this D2D communication set can, in the resource of the predefined moment and setting, send resource request and/or report data volume to be sent;

For example, in last of each radio frames, distribute in the D2D resource of this D2D communication set, each D2D UE sequentially sends resource request and/or reports data volume to be sent according to setting; If certain D2D UE does not have data to need to send, can not send resource request or report data volume to be sent, also can report data volume to be sent is 0.

In force, for the ease of realizing, preferred, this main D2D terminal can be in the resource of the moment of setting and setting, sends the scheduling situation of the D2D resource in lower a period of time to each the D2D terminal in this D2D communication set; For example, at first of each radio frames, distribute in the D2D resource of this D2D communication set, by main UE, to each the D2D terminal in this D2D communication set, sent the scheduling situation of the D2D resource in next radio frames.

In force, each D2D UE in this D2D communication set can be numbered, and the D2D resource for this D2D communication set configuration is also numbered to network side, when main D2D UE dispatches D2D resource, can adopt the numbering of D2D resource to be designated as the D2D resource that each D2D UE distributes.

For example, suppose to comprise two D2D UE in this D2D communication set, numbering is respectively 0 and 1, and wherein UE0 is main UE, in a radio frames, the resource that network side is distributed to this D2D communication set is resource 1(subframe 1), resource 2(subframe 3), resource 3(subframe 8), the data volume to be sent that main D2D UE reports according to other D2D UE and self data volume to be sent, in a radio frames, resource 1 is distributed to UE1, resource 2 is distributed to UE0 and resource 3 is distributed to UE1.

Mode B2, definite each the D2D terminal of each D2D terminal negotiation in this D2D communication set take the D2D resource having configured, are specially:

Network side indicates each the D2D terminal in described D2D communication set to adopt negotiation mode to determine each D2D terminal taking the D2D resource having configured by each D2D terminal.

Under which, when network side determines to be configured for the D2D resource of D2D communication for this D2D communication set, about each D2D UE in this D2D communication set, how to use the D2D resource having configured, by holding consultation between each D2D UE.

Preferably, network side can indicate each the D2D terminal in this D2D communication set to adopt negotiation mode to determine taking the D2D resource having configured in the following ways:

If mode 1 network side also carries the identification information of main D2D terminal in the signaling (as RRC signaling) that sends D2D resource allocation information, indicate each the D2D terminal in this D2D communication set to determine each D2D terminal taking the D2D resource having configured by main D2D terminal;

If network side does not carry any identification information in the signaling that sends D2D resource allocation information, indicate each the D2D terminal in this D2D communication set to adopt negotiation mode to determine taking the D2D resource having configured.

Mode 2, network side, after each the D2D terminal in this D2D communication set sends the configuration information of D2D resource, send indication information to each D2D terminal, to indicate each D2D terminal to adopt negotiation mode to determine taking the D2D resource having configured.

Accordingly, each D2D terminal in this D2D communication set is receiving the D2D resource of network side configuration, and determines while adopting negotiation mode to dispatch the D2D resource having configured, and adopts a kind of or combination in following manner to dispatch the D2D resource having configured:

Mode one, D2D terminal determining need to send data time, to other D2D terminals transmission resource bids except self in D2D communication set; D2D terminal, after receiving the positive acknowledgement (as ACK message) of at least one other D2D terminals transmission, sends data in the D2D resource of applying at self, and receives data in the D2D resource the D2D resource of applying for except self;

Wherein, when D2D terminal sends resource bid, the data volume that need to send according to self and the restriction of the maximum resource of setting, definite quantity that needs the resource of application.

Under which, for D2D UE the taking D2D resource in this D2D communication set, set the maximum resource restriction at every turn taking, for example, when D2D terminal is carried out resource bid at every turn, application takies the D2D resource of 2 subframes at most, to avoid arbitrary D2D terminal unrestrictedly to take D2D resource, and causes other D2D UE cannot take the situation of resource;

This D2D UE first notifies all D2D UE by broadcast mode, oneself 1～2 D2D resource in subframe will be taken, or take a part D2D resource (as the front half block Physical Resource Block in this subframe (Physical Resource Block, PRB)) in subframe; If the broadcast that this UE sends is carried out the feedback of positive acknowledgement (can adopt the signaling feedback of clean culture or broadcast) by arbitrary other D2D UE in this D2D communication set, the transmission of the enterprising row data of D2D resource that this D2D UE can apply at self, and other D2D UE can be in the reception of the enterprising row data of this D2D resource;

If the resource bid of this D2D UE clashes, the D2D UE that is two or more has carried out application identical or D2D resource that overlap, there is conflict in the resource bid of those D2D UE, the D2D that has sent this resource bid can not feed back positive acknowledgement, the D2DUE that conflict has occurred all can not receive positive acknowledgement each other, now, those D2D UE that clash can not be used applied for D2D resource.

Further, can adopt following either type to solve the conflict of resource bid:

First kind of way, by the D2D terminal that sends resource bid, solve this conflict, be specially:

If D2D terminal sends after resource bid in other D2D terminals except self in D2D communication set, do not receive the positive acknowledgement that any D2D terminal sends, this D2D terminal determines that resource bid that self sends and the resource bid of other D2D terminals clash;

This D2D terminal is selected time delay (as random passback (backoff) time delay) at random) and again to other D2D terminals transmission resource bids except self in D2D communication set; Or this D2D terminal, according to the occupancy mode of setting, determines whether to take applied for D2D resource.

Wherein, the occupancy mode of setting includes but not limited to following mode:

The priority of the D2D terminal clashing according to each, is used the D2D resource of applying for by the D2D terminal that priority is high; Or,

The D2D clashing according to each takies the situation of described D2D resource in setting duration, by taking the minimum D2D terminal of D2D resource, use the D2D resource of applying for, the D2D terminal of for example, not carrying out data transmission by the long period is used the D2D resource apply for; Or,

According to stipulated form rotation, use the D2D resource of applying for.

It should be noted that, above-mentionedly just enumerated several preferred occupancy modes, the embodiment of the present invention can also adopt other occupancy modes to manage conflict, as according to the numbering of D2D UE order from small to large, the D2D resource of applying for is used in rotation, is not enumerating herein.

Illustrate, resource bid with two D2D UE clashes as example, be UE1 and UE2, UE1 and UE2 all can not receive the other side's positive acknowledgement, now UE1 and UE2 all know that the resource bid of self has clashed, the processing that conflicts of its occupancy mode that can take to set, for example, the resource of UE1 is used priority to use priority higher than the resource of UE2, and UE1 and UE2 all give tacit consent to UE1 and use this D2D resource; And for example, if last UE1 is used the D2D resource apply for to carry out data receiver, when clashing, UE1 and UE2 all give tacit consent to by UE1 and use this D2D resource; For another example, when the resource bid of UE1 and UE2 clashes, by UE1 and UE2 rotation, use the D2D resource of applying for, as current wireless frame is used this D2D resource by UE1, next radio frames is used this D2D resource, successively rotation by UE2.

The second way, by the D2D terminal that does not send the resource bid with conflict simultaneously, solve this conflict, be specially:

Arbitrary D2D terminal in this D2D communication set determines that the resource bid of at least two D2D terminals except self clashes, this D2D terminal is according to the occupancy mode of setting, from the D2D terminal clashing, determine the D2D terminal that this uses the D2D resource of applying for, and notify each the D2D terminal clashing.

According to stipulated form rotation, use the D2D resource of applying for.

After mode two, the D2D terminal data that other D2D terminals except self send in correctly receiving this D2D communication set, to these other D2D terminals, return to feedback information, and in feedback information, carry resource occupation indication, in order to reservation, take at least one follow-up D2D resource; This D2D terminal sends data in the D2D resource of having preengage, and receives data in the D2D resource the D2D resource of having preengage except this.

Which is applicable to receiving in the mechanism of feedback, two the D2D UE of take are example, suppose that UE1 sends data on resource A, if UE2 correctly receives the data that this UE1 sends on this resource A, to UE1 feeding back ACK message, and in this feeding back ACK message, carry resource occupation indication, with the use of the D2D resource after reserve resource A.

For example, this UE2 can indicate explicit indication reservation to take this resource A D2D resource (as resource B) afterwards by this resource occupation; Accordingly, this UE1, after receiving the ACK message and resource occupation indication of UE2 feedback, receives in next D2D resource (being resource B) data that UE2 sends; If UE1 when receiving the ACK message of UE2 feedback, does not carry resource occupation indication, if UE1 also has data to need to send, continue to use next D2D resource (being resource B) to send data.Similarly, D2D UE can also indicate by resource occupation the D2D resource of the follow-up continuous a plurality of subframes of reservation.

Under which, if at least two D2D terminals have been preengage identical D2D resource, these at least two D2D terminals clash, and the D2D terminal that receives these at least two D2D terminal feedbacks can solve this conflict in the following ways:

According to the occupancy mode of setting, from all D2D terminals that clash, determine the D2D terminal that this uses the D2D resource of preengaging, and notify each the D2D terminal clashing.

The priority of the D2D terminal clashing according to each, is used the D2D resource of preengaging by the D2D terminal that priority is high; Or,

The D2D clashing according to each takies the situation of described D2D resource in setting duration, by taking the minimum D2D terminal of D2D resource, use the D2D resource of preengaging, the D2D terminal of for example, not carrying out data transmission by the long period is used the D2D resource preengage; Or,

According to stipulated form rotation, use the D2D resource of preengaging.

Mode three, D2D terminal are carried for representing that the indication of surplus of the data that self need to send or the data that send the last time carry the indication for representing that data all send in the data that send, wherein, other D2D terminals of this D2D communication set, after the data of determining this D2D terminal have been sent, adopt the mode of rotating or preempt-mode to take follow-up D2D resource.

Concrete, when arbitrary D2D UE has successfully seized D2D resource, and while starting to send data to other D2D UE in this D2D resource, can after the data that send, carry the surplus of data to be sent; Data transmission situation (comprising modulating-coding form etc.) due to each D2D UE, all D2D UE in this D2D communication set are clear, therefore when the data of D2D UE can be sent, and other D2D UE can predict according to the surplus of the data to be sent of carrying;

When arbitrary D2D UE has successfully seized D2D resource, and start to other D2D UE, to send after data in this D2D resource, when this D2D UE sends data the last time, can carry and be used to indicate the indication that self data are all sent, for example, this D2D UE can be at PDCP (the Packet Data Convergence Protocol of layer two (L2), PDCP), and/or wireless link is controlled (Radio Link Control, RLC), and/or medium access control packet data cell (MAC Packet Data Unit, MAC PDU) in head, utilize the R bit of 1bit to indicate current data to be all sent, for example, if R is 1, represent that data are all sent.Accordingly, for current, for sending the D2D resource afterwards of the D2D resource of data, other D2D UE can adopt the mode of rotating or the preempt-mode of setting, by next D2D UE, are used.
