Specific embodiment

The embodiment of the present invention is described in further detail with reference to the accompanying drawings of the specification.

It is shown in Figure 3, the resource allocation method in a kind of D2D communications provided in an embodiment of the present invention, including following step Suddenly:

Step 31, network side are according to the D2D business features to communicate and the currently used situation of resources in network, to have been established D2D communication sets in D2D terminals be configured to D2D communication D2D resources;

Specifically, the D2D terminals that D2D communication links have had been established comprising at least two in the D2D communication sets, the D2D lead to Any two D2D terminals in letter group can carry out D2D communications.

The configuration information of configured D2D resources is sent to each D2D in the D2D communication sets by step 32, network side Terminal;

Wherein, the occupancy of the configured D2D resources of each D2D terminal-pairs in D2D communications, is determined by network side and is notified It is determined to each D2D terminals or by the D2D terminals in the D2D communication sets.

The embodiment of the present invention propose a kind of network side to D2D communications the method that is configured using resource, in network Under control so that can be more flexible between each D2D terminals in D2D communication sets utilize D2D resources, so as to reduce D2D Interference between communication and conventional cellular communication, improves the handling capacity of system entirety, also improves user experience.

Preferably, network side uses wireless heterogeneous networks(Radio Resource Control, RRC)Signaling is the D2D Communication set is configured to the D2D resources of D2D communications.

Preferably, network side is used within the set duration or before deactivation for the D2D resources of D2D communication sets configuration D2D communicates, i.e., network side uses the D2D resources for being semi-statically configured and D2D communications being configured to for the D2D communication sets;

Further, network side can also carry when being semi-statically configured and be used to indicate the effective of the resource distribution The instruction information of time range;

Specifically, if current time is in the effective time range of the resource distribution, resource distribution failure or Person is after the deactivation command for the resource distribution for receiving network side transmission, resource distribution failure.

In force, in step 31, if network side determines that establishing D2D between two D2D UE or one group of D2D UE leads to Believe link, then:Network side is established D2D according to the D2D business features to communicate and the currently used situation of resources in network D2D terminals in communication set are configured to the D2D resources of D2D communications.

For example, the business of the D2D communications of the D2D communication sets has typical ensures bit rate(Guaranteed Bit Rate, GBR)Business feature, such as video conversation business etc. have specific transmission rate request, then the network side is determined as D2D terminals configuration D2D resources in the D2D communication sets use so that D2D communicates;

For another example, the business of the D2D communications of the D2D communication sets downloads class, such as File Transfer Protocol for data(File Transport Protocol, FTP)Deng, although without GBR requirements, in entire transmission cycle, data transmission rates demands Relatively fixed, such as download the file of 20M, then the network side can be current according to the resource scheduling algorithm of setting, resources in network The user rate requirements of D2D UE signings in service condition and the D2D communication sets are D2D communication sets distribution for D2D The D2D resources of communication, so that data transmission uses;

For another example, when Internet resources are looser or currently have been configured as referring to via the resource of the communication path of core net It can be communicated and be multiplexed, such as the resource distributes to one via core net by semi-static by D2D in the range of fixing time The UE that network communicates, and the traditional communication link of the UE(I.e. via the communication path of core net)It is done between D2D links Disturb it is smaller, meet setting multiplexing rule, then the network side can be multiplexed the part resource, within a specified time should Part resource is allocated to the D2D communication sets and is used so that D2D communicates, so as to save the control letter of network dynamic scheduling D2D resources Enable expense;

For another example, work as network side(Such as eNB)Control signaling expense occupy larger, and D2D communication services of the D2D communication sets It is delayed when can endure certain, which can also give the D2D communication sets that semi-static D2D resources are configured, to save control The expense of signaling processed.

Preferably, in step 31, network side is that semi-static D2D moneys are configured in the D2D terminals in established D2D communication sets Source, the D2D resources communicate within the set duration or before being deactivated for D2D.

In force, network side is as follows for a kind of preferred configuration mode of the D2D resources of D2D communication sets configuration:

Corresponding resource pattern in frequency point+running time-frequency resource specific location+time domain(pattern);Alternatively,

Frequency point+running time-frequency resource specific location+repetition period.

It should be noted that D2D resources can be configured for the D2D communication sets on same frequency point in network side, it can also D2D resources are configured for the D2D communication sets on different frequent points;Repetition period of the network side for the D2D resources of D2D communication sets configuration Can be all identical, can also part it is identical, can also differ entirely.

In force, a kind of preferred resources employment methods are that in step 31, network side is configured more for the D2D communication sets Kind is used for the configuration of the D2D resources of D2D communications, and the D2D moneys that all kinds be configured for the D2D communication sets are communicated for D2D The configuration information in source is sent to each D2D terminals.

Preferably, the size of D2D resources that configuration not of the same race includes has difference, if configuration not of the same race provides different biographies Defeated rate, to cope with the variation of data volume;

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

The first configuration includes resource block 1 and resource block 2, and the repetition period is T;

Second of configuration is only comprising resource block 2, repetition period T.

In above two configuration, the first is configured, and occupied resource is more, and the transmission rate being capable of providing is higher, and second Kind configuration is compared to the first configuration, and occupied resource is less, and the transmission rate being capable of providing is smaller.

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

The first configuration includes resource block 1, and the repetition period is T;

Second of configuration includes resource block 2, repetition period 2T.

In above two configuration, the first is configured, and occupied resource is more, and the transmission rate being capable of providing is higher, and second Kind configuration is compared to the first configuration, and occupied resource is less, and the transmission rate being capable of providing is smaller.

It should be noted that the configuration of a variety of D2D resources of the D2D communication sets, at the same moment, can only use wherein A kind of D2D resources configuration.

If network side is configured with the configuration of a variety of D2D resources for D2D communications for D2D communication sets,:Network side with The configuration of D2D resources that D2D communication sets use when can make an appointment initial;Alternatively, network side indicates that the D2D communication sets are current The configuration of D2D resources being active.

Specifically, the configuration that network side can be used with the D2D terminals of D2D communication sets agreement when initial in advance;For example, net Network side sends the configuration of 5 kinds of D2D resources by RRC signaling to each D2D terminals of the D2D communication sets, and network side communicates with D2D The D2D terminals of group carry out D2D communications when making an appointment initial using the first resource distribution, then each D2D terminals are at the beginning Use the first resource distribution;

Network side can also be when sending the configuration for all D2D resources of its configuration to the D2D communication sets, and instruction should The D2D terminals of D2D communication sets are currently at the configuration of the D2D resources of state of activation;For example, the network side by RRC signaling to The D2D communication sets send the configuration of 5 kinds of D2D resources, and when passing through the RRC signaling and indicating the D2D terminal initials of the D2D communication sets All D2D communications are carried out using the configuration of the first D2D resource;

Network side can also by RRC signaling to the D2D communication sets send for its configuration all resource distributions and then Indicate that the D2D terminals of the D2D communication sets are currently at the configuration of the D2D resources of state of activation by L2/L1 signalings, so that each D2D terminals currently all carry out D2D communications using the configuration of the D2D resources using state of activation.

Preferably, L2(Layer2)Signaling refers mainly to media access control(Media Access Control, MAC)Letter It enables, specifically with media access control layer control unit(MAC Control Element, MAC CE)Form carrying;L1 (Layer1)Signaling refers mainly to physical layer signaling, specifically with Physical Downlink Control Channel(Physical Downlink Control Channel, PDCCH)Form carrying.

In force, network side can arrange to identify matching for a variety of D2D resources in the form of number with D2D communication sets It puts, such as number 0 represents the configuration of the first D2D resource, and number 1 represents the configuration of second of D2D resource, and so on, in this way, Network side is when the D2D terminals for indicating the D2D communication sets are currently at the configuration of D2D resources of state of activation, it is only necessary to which carrying should The corresponding number of resource distribution.

Further, after the lateral D2D communication sets of network send the configuration for all D2D resources of its configuration, the net Network side can also signal each D2D terminals pause matching using any D2D resources in the D2D communication sets by L2/L1 It puts, waits for dynamic dispatching of the network side to resource distribution.

In force, a kind of configuration of the D2D resources for D2D communications is configured with if network side is only the D2D communication sets, Then:The network side can first pass through RRC signaling and D2D resources are configured for the D2D communication sets, then be led to by L2/L1 signalings to the D2D Each D2D terminals in letter group send the instruction for activating the resource distribution or the instruction for deactivating the configuration.

In force, if network side determines that the business feature of the D2D communications of the D2D communication sets changes(Such as D2D links On increased or decreased a D2D communication service)Or the currently used situation of resources in network changes, it is current in order to be applicable in D2D communication services requirement, this method further includes:

Network side is that the D2D terminals in the D2D communication sets reconfigure the D2D resources to communicate for D2D;And

Reconfiguration information is sent to each D2D terminals in the D2D communication sets by network side, and indicates each D2D terminals The reconfiguration information comes into force the moment.

Specifically, the moment of coming into force of reconfiguration information is generally subject to the absolute moment, for example, the reconfiguration information comes into force Moment can be System Frame Number(System Frame Number, SFN);

Network side can carry to refer to when each D2D terminals into the D2D communication sets send the reconfiguration information Show the instruction information at the moment of coming into force of the reconfiguration information, can also be sent in each D2D terminals into the D2D communication sets should After reconfiguration information, the moment of coming into force of the reconfiguration information is used to indicate to the transmission of each D2D terminals by L2/L1 signalings Indicate information.

It is the serving cell of each D2D UE respectively to it should be noted that in above-mentioned configuration and reconfiguration course Each UE of service carries out signal deployment.If the serving cell of the D2D UE in the D2D communication sets belongs to same eNB, Then the eNB can determine the distribution condition of D2D resources according to the resource scheduling algorithm of therein;If the D2D communication sets In the serving cell of D2D UE belong to two or more eNB, then when determining D2D resource allocations, different eNB it Between need to interact and negotiate, with the situation of unified resource distribution and other relevant configurations(The identification information of such as main UE, feedback The information such as configuration, the occupancy rule of setting).

Preferably, if the different eNB that the serving cell of each D2D UE in the D2D communication sets belongs to correspond to same control Node processed, then during to the resource distribution to communicate for D2D of the D2D communication sets and other relevant configurations, Ke Yiyou The control node carries out unified decision and management, then respectively to the service eNB of each D2D UE send resource allocation information and Resource allocation information is finally sent to corresponding D2D UE by other configurations information by each service eNB.

In force, each D2D terminal-pairs network side in the D2D communication sets is the D2D resources of D2D communication sets configuration Occupancy, including following two methods of determination:

Mode A, the occupancy of D2D resources that each D2D terminal-pairs in the D2D communication sets are configured is determined by network side, and It notifies to each D2D terminals;

In force, mode A is further again including following two modes:

Mode A1, the D2D resources for being configured for the D2D communication sets, network side explicit instruction itself are each D2D terminals The transmission resource for transmission data specified, specially:

Network side specifies the transmission resource for transmission data for each D2D terminals when D2D resources are configured;Network side All D2D terminals transmission resource that itself is each D2D terminal distributions being sent in D2D communication sets;

Correspondingly, for each D2D terminals in D2D communication sets, D2D terminals are receiving network side as D2D communications It is transmission data in the transmission resource itself specified in the network side after the transmission resource that each D2D terminals in group are specified, Data are received in the transmission resource that other D2D terminals in network side is the D2D communication set in addition to itself are specified.

Under which, network side be determined as the D2D communication sets be configured to D2D communication D2D resources when, can be simultaneously Correspondence between D2D resources and each D2D UE provides or respectively each D2D UE distribute dedicated D2D Resource, but the information for the D2D resources distributed for each D2D UE must be sent to the institute in the D2D communication sets by the network side There are D2D UE.

For example, it is assumed that two the D2D UE that D2D links have been established, i.e. UE1 and UE2, network side are included in the D2D communication sets For the D2D communication sets distribution D2D resource collections be(Resource A, resource B), wherein, the repetition period T of D2D resources(Certainly, this In repetition period can also be more complicated form, for example different resources has the different repetition period or different Resource has a different pattern, such as resource A only effective in the radio frames that SFN is odd number, and resource B is even number only in SFN Radio frames are effective), then the network side explicit instruction resource A can be used in configuration signal by UE1(That is UE1 is enterprising in resource A Row data are sent, then UE2 carries out data receiver on resource A), similar, which can explicitly refer in configuration signal Show that resource B is used by UE2(That is UE2 carries out data transmission on resource B, then UE1 carries out data receiver on resource B);

For another example, it is assumed that two the D2D UE that D2D links have been established, i.e. UE1 and UE2, network side are included in the D2D communication sets It is assigned with for UE1 for the D2D resource A to communicate and is that UE2 is assigned with the resource B to communicate for D2D, wherein, resource A tools Having the repetition specified pattern, either repetition period T1 resources B has the repetition pattern specified or repetition period T2, Then the network, in addition to the distribution information of the D2D resources comprising this UE, also includes in the resource allocation signaling of UE1 and UE2 is issued The distribution information of the D2D resources of other side UE, in order to work as this UE transmission datas in D2D resource of the network side for itself distribution When, other side UE can carry out data receiver on the same resource.

It should be noted that during above-mentioned two illustrates, only said so that D2D communication sets include two D2D UE as an example Bright, when more than two D2D UE are included in the D2D communication sets, the assigning process of D2D resources is carried out for each D2D UE is Similar, i.e. the network side is each needs the D2D UE for carrying out D2D communications to distribute D2D resources in the D2D communication sets, and by institute The distribution information for having the D2D resources of D2D UE is sent to all D2D UE involved in the D2D communication sets.

It is the D2D that mode A2, network side, which are made an appointment with the D2D communication sets to the occupancy mode or network side of D2D resources, Resource occupation pattern is configured in communication set(pattern)And the resource occupation image is sent to each D2D terminals, it is each to indicate D2D terminals use D2D resources according to the resource occupation pattern;

Under which, the occupancy mode of D2D resources if network side and the D2D communication sets have been made an appointment, the network side D2D terminals for the D2D communication sets are configured with after the D2D resources to communicate for D2D, and the configuration information of the D2D resources is sent out Give each D2D terminals;Correspondingly, each D2D terminals after the configuration information for receiving the D2D resources, are made a reservation for using advance Occupancy mode(As rotation uses), communicated using the D2D resources.

Under which, network side is configured resource occupation pattern for the D2D communication sets and is specially:

Network side is configured to indicate that each D2D is whole after D2D resources are configured for D2D communication sets, for the D2D communication sets Hold the resource occupation pattern to the occupancy of D2D resources;The resource occupation pattern is sent to each D2D terminals by network side, wherein, Each D2D terminals use D2D resources using the resource occupation pattern of network side configuration.

Preferably, network side can be in same RRC signaling by the configuration information of D2D resources and resource occupation pattern It is sent to each D2D terminals;The configuration information of D2D resources first can also be sent to each D2D terminals by network side, be reinformed every A D2D terminals resource occupation pattern.

It, can be right simultaneously when D2D resources are configured in the D2D UE that network side is determined as in the D2D communication sets under which Each D2D UE provide the occupancy rule of D2D resources in the D2D communication sets, obtain the corresponding resource of each D2D terminals and account for Use pattern.

For example, using the resource block in each subframe as a D2D resource, each D2D is used alternatingly by all D2D UE Resource transmission data.And when carrying out D2D resource distributions, while provide the sequence that uses of all D2D UE, such as give each D2D UE is numbered, and the D2D resources are used according to the sequence of number from small to large.Using the D2D communication sets include two D2D UE as Example, it is assumed that network side is assigned with resource in subframe 3 and subframe 6 for the D2D communication sets and is used as the D2D resources to communicate for D2D, The network side notifies that the resource occupation pattern to each D2D terminals can be, the UE1 that number is 1 uses the D2D moneys in subframe 3 Source, the UE2 that number is 2 use the D2D resources in subframe 6;

For another example, if the data volume asymmetry that UE1 and UE2 needs are sent, network side are assigned with subframe 3 for the D2D communication sets, Resource in subframe 6 and subframe 8 is as the D2D resources for D2D communications, in each radio frames, subframe 3 and subframe 6, and subframe 8 include the D2D resources for D2D communications respectively, then the network side is notified to the resource occupation pattern of each D2D terminals Can be that the UE1 that number is 1 uses the D2D resources in subframe 3 and subframe 6, the UE2 that number is 2 uses the D2D moneys in subframe 8 Source;

For another example, the resource block in each subframe is divided into multiple D2D resources, if the D2D communication sets include 4 D2D UE, network side are assigned with resource in subframe 3 and subframe 6 for the D2D communication sets and are used as the D2D resources to communicate for D2D, wherein Resource in subframe 3 is divided into 2 D2D resources, and the resource of subframe 6 is also divided into 2 D2D resources, then network side is is somebody's turn to do In D2D communication sets the resource occupation pattern of each D2DUE configuration can be UE1 and number that number is 1 be 2 UE2 according to For setting sequence using two D2D resource transmission datas in subframe 3, the UE4 that the UE3 and number that number is 3 are 4 is suitable according to setting Sequence uses two D2D resource transmission datas in subframe 6.

Table 1 gives the example of a specific implementation form of the resource occupation pattern of network side configuration:

Table 1

It should be noted that table 1 is only intended to illustrate the resource occupation pattern, it is not intended to limit the resource occupation pattern Specific implementation form, the resource occupation pattern can also use other ways of realization

Under which, network side can be that all D2D terminals configuration one in the D2D communication sets is used to indicate each D2D The resource occupation pattern of the occupancy situation of terminal-pair D2D resources can also be directed to each D2D terminals configuration one and be used to indicate this The resource occupation pattern of the occupancy situation of D2D terminal-pair D2D resources.

Mode B, the occupancy that the configured D2D resources of each D2D terminal-pairs are determined by the D2D terminals in D2D communication sets;

In force, mode B is further again including following two realization methods:

Mode B1, a main D2D terminal is selected by network side, by the main D2D terminals for each in the D2D communication sets D2D terminals are scheduled D2D resource of the network side for D2D communication sets configuration, specially:

Network side selectes a D2D terminal as main D2D terminals, and selected main D2D is whole from the D2D communication sets The identification information at end notified to each D2D terminals in the D2D communication sets, wherein, which is used to communicate in the D2D The D2D resources of scheduling in group network side configuration.

Under which, when the D2D terminals that network side is determined as in the D2D communication sets are configured to the D2D resources of D2D communications When, can also a main D2D terminal, and each D2D in the explicit instruction D2D communication sets be configured for the D2D communication sets simultaneously Terminal determines the scheduling to configured D2D resources by the main D2D terminals.

A kind of preferred specific implementation under which is given below:

Main D2D UE are configured when D2D resources are configured to the D2D UE in D2D communication sets in network side, and notify to be somebody's turn to do The identification information of all D2D UE main D2D UE in D2D communication sets, so that each D2D UE in the D2D communication sets can Know the main D2D UE which D2D UE is network side configuration;

Correspondingly, each D2D UE in the D2D communication sets receive D2D resources and the instruction of network side configuration Afterwards, the main D2D UE in the D2D communication sets are determined.Further, when any D2D UE in the D2D communication sets need transmission data When, which sends resource request to main D2D UE and/or reports data volume to be sent;The main D2D UE are receiving it After the resource request of his D2D UE transmissions and/or the data volume to be sent reported, according to the scheduling rule of setting, to network side The D2D resources of configuration are allocated, and are transmission resource of the D2D UE distribution in the D2D communication sets for transmission data, and by The distribution condition of D2D resources is sent to each D2D UE;D2D UE in the D2D communication sets are according to the D2D resources received Distribution condition carries out the transmission of data in the transmission resource that the main D2D UE are itself distribution, is except certainly in the main D2D UE The data of other D2D UE transmissions are received in the transmission resource of other D2D UE distribution except body.

Further, main D2D UE also consider D2D communications when the D2D resources that network side is configured are scheduled The information such as the data volume of all D2D UE and respective priority in group.

For example, main D2D UE carry out D2D resources from high to low according to the priority of each D2D UE in the D2D communication sets Scheduling, i.e., the D2D UE transmission datas of main D2D UE elder generations schedules high priority, the D2D UE of all high priorities have all been sent Finish, then schedules low priority UE transmission datas;

For another example, each priority D2D UE are assigned with a GBR(Ensure bit rate), other are determined in main D2DUE When the resource request that D2D UE are sent clashes, first ensure that the D2DUE of high priority reaches guarantee bit rate, it is remaining The guarantee bit rate of the D2D UE of D2D Resource Guarantee low priorities, if also remaining D2D resources, according still further to priority It is allocated from high to low.

Preferably, network side can be in the configuration signal of D2D resources(Such as RRC signaling)It is middle to carry selected main D2D terminals Identification information;D2D resources can also be configured for the D2D communication sets, then this is signaled by L2/L1 to by RRC signaling The identification information of each D2D terminals main D2D terminals in D2D communication sets.

In force, for the ease of realization, it is preferred that the D2D terminals of the D2D communication sets can be at the time of presetting In the resource of setting, send resource request and/or report data volume to be sent;

For example, in the last one D2D resource for distributing to the D2D communication sets of each radio frames, each D2D UE according to Setting sequence sends resource request and/or reports data volume to be sent;It, can be with if some D2D UE does not have data to need to send Resource request is not sent or reports data volume to be sent, and it is 0 that can also report data volume to be sent.

In force, for the ease of realization, it is preferred that the resource that the main D2D terminals can be at the time of setting with setting On, each D2D terminals into the D2D communication sets send the dispatch situation of the D2D resources in lower a period of time;For example, every It is whole from each D2Ds of the main UE into the D2D communication sets in the D2D resources that first of a radio frames distributes to the D2D communication sets End sends the dispatch situation of the D2D resources in next radio frames.

In force, each D2D UE in the D2D communication sets can be numbered, and network side is led to for the D2D The D2D resources of letter group configuration are also numbered, and when main D2D UE are scheduled D2D resources, the volume of D2D resources may be used Number it is designated as the D2D resources of each D2D UE distribution.

For example, it is assumed that comprising two D2D UE in the D2D communication sets, number is respectively 0 and 1, and wherein UE0 is main UE, In one radio frames, the resource that network side distributes to the D2D communication sets is resource 1(Subframe 1), resource 2(Subframe 3), resource 3 (Subframe 8), then main D2D UE are according to other D2D UE data volumes to be sent reported and itself data volume to be sent, one In a radio frames, resource 1 is distributed into UE1, resource 2 is distributed into UE0 and resource 3 is distributed into UE1.

Mode B2, negotiated to determine the D2D resources that each D2D terminal-pairs are configured by each D2D terminals in the D2D communication sets Occupancy, specially:

It is each that network side indicates that each D2D terminals in the D2D communication sets are determined by each D2D terminals using negotiation mode The occupancy of the configured D2D resources of D2D terminal-pairs.

Under which, when network side, which is determined as the D2D communication sets, is configured to the D2D resources of D2D communications, about this How each D2D UE are using configured D2D resources in D2D communication sets, by holding consultation between each D2D UE.

Preferably, network side may be used in the following manner and indicate that each D2D terminals in the D2D communication sets use negotiation side Formula determines the occupancy to configured D2D resources:

If mode 1, network side are in the signaling for sending D2D resource allocation informations(Such as RRC signaling)In also carry main D2D terminals Identification information, it indicates that each D2D terminals in the D2D communication sets determine that each D2D terminal-pairs are configured by main D2D terminals D2D resources occupancy;

If network side does not carry any identification information in the signaling for sending D2D resource allocation informations, it indicates that the D2D leads to Each D2D terminals in letter group determine the occupancy to configured D2D resources using negotiation mode.

After the configuration information that mode 2, network side send D2D resources in each D2D terminals into the D2D communication sets, Instruction information is sent to each D2D terminals, to indicate that each D2D terminals are determined using negotiation mode to configured D2D resources Occupancy.

Correspondingly, each D2D terminals in the D2D communication sets are in the D2D resources for receiving network side configuration, and determine to use When negotiation mode is scheduled configured D2D resources, configured D2D is provided using one kind in following manner or combination Source is scheduled:

When determining to need transmission data, other D2D into D2D communication sets in addition to itself are whole for mode one, D2D terminals End sends resource bid;D2D terminals are in the positive acknowledgment for receiving at least one other D2D terminals transmission(Such as ACK message)Afterwards, The transmission data in itself apllied D2D resource, and received in the D2D resources in addition to itself apllied D2D resource Data;

Wherein, when D2D terminals send resource bid, the data volume and the maximum resource of setting that send according to their needs Limitation determines the quantity of resource for needing to apply.

Under which, for the D2D UE in the D2D communication sets to the occupancy of D2D resources, the maximum occupied every time is set Resource constraint, for example, when D2D terminals carry out resource bid every time, at most application occupies the D2D resources of 2 subframes, to avoid appointing One D2D terminals unlimitedly occupy D2D resources, and cause other D2D UE that can not occupy the situation of resource;

The D2D UE first pass through broadcast mode and notify all D2D UE, oneself provides the D2D occupied in 1~2 subframe Part D2D resources in one subframe in source or occupancy(Preceding half block Physical Resource Block in such as subframe(Physical Resource Block, PRB));If the broadcast message that the UE is sent is carried out by other any D2D UE in the D2D communication sets Positive acknowledgment(The signaling feedback of unicast or broadcast may be used)Feedback, then the D2D UE can be apllied at itself The transmission of data is carried out in D2D resources, and other D2D UE can carry out the reception of data in the D2D resources;

If the resource bid of the D2D UE clashes, i.e. two or more D2D UE carried out it is identical or The application of D2D resources to overlap, the then resource bid of those D2D UE are conflicted, and have sent the resource bid D2D will not feed back positive acknowledgment, that is, the D2DUE to be conflicted will not receive mutual positive acknowledgment, at this point, those are sent out The D2D UE of raw conflict can not be used apllied D2D resources.

Further, it is possible to the conflict of resource bid is solved using following either type:

First way solves the conflict by the D2D terminals of transmission resource bid, specially:

If D2D terminals do not receive after other D2D terminals into D2D communication sets in addition to itself send resource bid The positive acknowledgment sent to any D2D terminals, then the D2D terminals determine the resource bid and other D2D terminals that itself send Resource bid clashes;

The D2D terminals randomly choose time delay(Such as random passback(backoff)Time delay))And again into D2D communication sets Other D2D terminals in addition to itself send resource bid;Alternatively, the D2D terminals decide whether according to the occupancy mode of setting Occupy apllied D2D resources.

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

According to each priority of D2D terminals clashed, apllied D2D is used by the high D2D terminals of priority Resource;Alternatively,

The situation of the D2D resources is occupied within the set duration according to each D2D clashed, by occupying D2D resources Minimum D2D terminals use apllied D2D resources, for example, the D2D terminals for not carrying out data transmission by the long period use institute The D2D resources of application;Alternatively,

Apllied D2D resources are used according to stipulated form rotation.

It should be noted that above-mentioned only list several preferred occupancy modes, the embodiment of the present invention can also use Other occupancy modes solve conflict, and such as sequence according to the number of D2D UE from small to large, rotation are provided using apllied D2D Source is not enumerating herein.

For example, by taking the resource bid of two D2D UE clashes as an example, i.e. UE1 and UE2, then UE1 and UE2 is not The positive acknowledgment of other side can be received, UE1 and UE2 knows that the resource bid of itself clashes at this time, can take and set Fixed occupancy mode carries out clash handle, for example, the resource use priority of UE1 is higher than the resource use priority of UE2, then UE1 and UE2 gives tacit consent to UE1 and uses the D2D resources;For another example, it is connect if last time UE1 carries out data using apllied D2D resources It receives, then when clashing, UE1 and UE2 give tacit consent to uses the D2D resources by UE1;For another example, when the resource bid of UE1 and UE2 When clashing, by UE1 and UE2 rotations using apllied D2D resources, such as current radio frames use the D2D resources by UE1, Next radio frames use the D2D resources, successively rotation by UE2.

The second way solves the conflict by the D2D terminals for not sending the resource bid with conflict simultaneously, specially:

Any D2D terminals in the D2D communication sets determine the resource bid hair of at least two D2D terminals in addition to itself From the D2D terminals clashed, it is apllied to determine that this is used according to the occupancy mode of setting for raw conflict, the D2D terminals The D2D terminals of D2D resources, and notify each D2D terminals clashed.

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

According to each priority of D2D terminals clashed, apllied D2D is used by the high D2D terminals of priority Resource;Alternatively,

The situation of the D2D resources is occupied within the set duration according to each D2D clashed, by occupying D2D resources Minimum D2D terminals use apllied D2D resources, for example, the D2D terminals for not carrying out data transmission by the long period use institute The D2D resources of application;Alternatively,

Apllied D2D resources are used according to stipulated form rotation.

What other D2D terminals of mode two, D2D terminals in the D2D communication sets are had correctly received in addition to itself were sent After data, feedback information is returned to other D2D terminals, and resource occupation instruction is carried in feedback information, to account for about in advance With subsequent at least one D2D resources;D2D terminals transmission datas in the D2D resources preengage, and except this has preengage Data are received in D2D resources except D2D resources.

Which is suitable for the mechanism for receiving feedback, by taking two D2D UE as an example, it is assumed that UE1 is sent out on resource A Data are sent, if UE2 has correctly received the data of UE1 transmissions on resource A, to UE1 feeding back ACK message, and it is anti-at this While presenting ACK message, resource occupation instruction is carried, with the use of the D2D resources after reserve resource A.

For example, the UE2 can indicate that explicit instruction reservation occupies a D2D after resource A by the resource occupation Resource(Such as resource B);Correspondingly, the UE1 receive UE2 feedback ACK message and resource occupation instruction after, next D2D resources(That is resource B)Receive the data that UE2 is sent;If UE1 does not have while the ACK message for receiving UE2 feedbacks Resource occupation instruction is carried, if then UE1 also data need to send, is continuing with next D2D resources(That is resource B)Hair Send data.Similar, D2D UE can also indicate the D2D resources of the subsequent continuous multiple subframes of reservation by resource occupation.

Under which, if at least two D2D terminals are subscribed to identical D2D resources, i.e., at least two D2D terminals occur Conflict, then the D2D terminals for receiving at least two D2D terminals feedback may be used in the following manner and solve the conflict:

According to the occupancy mode of setting, from all D2D terminals clashed, determine that this uses preengage D2D The D2D terminals of resource, and notify each D2D terminals clashed.

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

According to each priority of D2D terminals clashed, preengage D2D is used by the high D2D terminals of priority Resource;Alternatively,

The situation of the D2D resources is occupied within the set duration according to each D2D clashed, by occupying D2D resources Minimum D2D terminals use preengage D2D resources, for example, the D2D terminals for not carrying out data transmission by the long period use institute The D2D resources of reservation;Alternatively,

Preengage D2D resources are used according to stipulated form rotation.

Mode three, D2D terminals carry to represent itself to need the surplus of data sent in the data of transmission Indicate or the data that are sent in last time in carry for representing instruction that data have all been sent, wherein, D2D communications Other D2D terminals of group are after the data for determining the D2D terminals have been sent, using alternation mode or preempt-mode to rear Continuous D2D resources are occupied.

Specifically, accounting for D2D resources when any D2D UE are successfully robbed, and start in the D2D resources to other D2D UE During transmission data, the surplus of data to be sent can be carried behind the data of transmission;Since the data of each D2D UE are sent out It gives a present condition(Including modulating-coding form etc.), all D2D UE in the D2D communication sets are aware that, thus the data of D2D UE what When can be sent, other D2D UE can be predicted according to the surplus of the data to be sent of carrying;

D2D resources are accounted for when any D2D UE are successfully robbed, and are started in the D2D resources to other D2D UE transmission datas Afterwards, which can carry in last time transmission data and be used to indicate the finger that the data of itself have all been sent Show, for example, the D2D UE can be in layer two(L2)Packet Data Convergence Protocol(Packet Data Convergence Protocol, PDCP), and/or wireless spread-spectrum technology(Radio Link Control, RLC), and/or Media access contorl point Group data cell(MAC Packet Data Unit, MAC PDU)Head in, indicate current number using the R bits of 1bit According to being all sent, if for example, R is 1, then it represents that data are all sent.Correspondingly, it is sent for being currently used in The alternation mode or preempt-mode of setting may be used in D2D resources after the D2D resources of data, other D2D UE, by Next D2D UE are used.
