Referring to FIG. 3, the method flow diagram of V2X communication is carried out for terminal device in the prior art, in following introduction Cheng Zhong, with application scenarios shown in Fig. 2A, and at least two terminal devices are the terminal device for carrying out V2X communication.The party Method is described as follows:

Window and resource selection window are listened in step 301, determination.

Specifically, after terminal device is connect with base station, base station can be used for the money of V2X communication for the terminal equipment configuration Source pond, the resource pool are the set of multiple running time-frequency resources.Such as terminal device needs to send V2X business datum in subframe n, then eventually End equipment determines that the range of resource selection window in the time domain is subframe [n+T1, n+T2], wherein T₁≤ 4, and 20≤T₂≤ 100, The delay requirement of the V2X business datum determines according to T2, and determines that listening to the range of window in the time domain is subframe [n- 1000, n-1], as shown in figure 4, listening to window and resource selection window for what the terminal device determined.

Step 302 is listened to and carries out information monitoring in window at this.

Terminal device needs to monitor subframe n-1000 into subframe n-1, in addition to the terminal device itself has V2X business datum The sidelink of remaining subframe except the subframe of transmission controls information (sidelink control information, SCI) With sidelink received signal strength indicator (sidelink received signal strength indicator, S- RSSI)。

Step 303, the SCI information sifting resource according to detection.

Terminal device determines set S first_A, and will set S_ABe initialized as including in the resource selection window is multiple alternative The union of resource.

Then, terminal device is from set S_AThe middle alternative resource R for excluding itself and needing to occupy_{X, y}.In the prior art, one A alternative resource R for data transmission_x,yIt is defined as subframeIn L_sub_CHA continuous subchannel x+j, wherein j=0 ..., L_subCH-1.Specifically, itself needs the alternative resource R occupied_{X, y}Method of determination are as follows: assuming that the terminal device did not detected Subframe isThere are an integer j, meet y+j × P '_{rsvp_TX}=z+P_step× k, wherein j=0,1 ..., C_resel- 1, P_{rsvp_TX} =P_step×P_{rsvp_TX}/ 100, k are any of higher level parameters restrictResourceReservationPeriod instruction permission Value.After terminal device determines the alternative resource for itself needing to occupy, then the alternative resource is excluded from set SA.

Further, terminal device excludes the alternative money of other terminal devices occupancy according to the SCI detected from set SA Source R_{X, y}.Wherein, the specific method of determination for the alternative resource that other terminal devices occupy are as follows:

Terminal device is in subframe" resource reservation " domain for having received a SCI, and including in the SCI and " priority " Domain has indicated respectively value P_{rsvp_RX}And prio_RX, and the data reference signal of the SCI received receives power (reference Signal received power, RSRP) value be higher thanThen terminal device is in subframeThe SCI that receives or Person is estimated in subframeThe time-frequency domain resources that the SCI that will receive is determined withThere is overlapping, wherein q =1,2 ..., Q, and j=0,1 ..., C_resel-1.Work as P_{rsvp_RX}< 1 and n-m≤P_step×P_{rsvp_RX}When,Otherwise Q =1.So that it is determined that going out the alternative resource R that other terminal devices occupy_{X, y}。

After terminal device determines the alternative resource that other terminal devices occupy, then from set S_AMiddle exclusion alternative money Source.

If terminal device is from set S_AThe middle alternative resource for excluding itself occupancy and other terminal devices occupy alternative After resource, set S_AThe quantity for the remaining alternative resource for including is less than 0.2M_total, wherein M_totalInclude for resource selection window Multiple sub-frame resources sum, then by Th_a,bIt reduces 3dB and repeats step 303.

Step 304 determines alternative resource set.

For set S_AThe remaining alternative resource for including, passes through index E_x,yTo determine alternative resource set.Index E_x,yIt is fixed Justice is the linear average of the RSSI measured on the subchannel x+k detected in step 302, wherein k=0 ..., L_subCH-1.From Set S_AIn select index E_x,yThe smallest alternative resource is as the alternative resource met the requirements, by index E_x,yIt is the smallest alternative Resource moves into set S_BIn.Then step 304 is repeated, until set S_BIn quantity be more than or equal to 0.2M_total.Set S_BI.e. For alternative resource set.

Step 305, from alternative resource set S_BMiddle random selection resource is for sending V2X business datum.

It can be seen that from the above process in the prior art, only when a certain resource is occupied by some terminal device, He can know that the resource is occupied by listening to process by terminal device.If terminal device selection is periodically to provide Source, then other terminal devices can know that the resource is the resource periodically used by the above process, then subsequent to be provided Can be carried out to the resource a degree of evade when source selection or gravity treatment；If terminal device selection is dynamic resource, That is, the resource is only only used once, for example, paroxysmal V2X business datum, then other terminal devices in advance can not be by above-mentioned Process knows that the dynamic resource is occupied, therefore can not evade to subsequent resource.

Therefore, for acyclic business datum, for example, paroxysmal business datum, if continuing to use existing skill completely Resource selection process in art one can not know the paroxysmal business number of other terminal devices when terminal device selects resource According to the resource of occupancy, identical resource is selected to send respective paroxysmal business number so may cause multiple terminal devices According to reduce the transmission reliability of paroxysmal business datum.

In consideration of it, the embodiment of the present application provides a kind of communication means, the transmission that can be improved paroxysmal business datum can By property.Technical solution provided by the embodiments of the present application is carried out in conjunction with appended figures and specific embodiments detailed Thin explanation.

During following introduction, applied field shown in Fig. 2A is applied to technical solution provided by the embodiments of the present application Scape is base station with the network equipment, and the first communication equipment is first terminal equipment, and, the second communication equipment is that second terminal is set For standby.

Referring to FIG. 5, being a kind of flow chart of communication means provided by the embodiments of the present application, this method is described as follows:

Step 501, first terminal equipment determine first resource, and the first resource is for sending the first data.

In the embodiment of the present application, any terminal in application scenarios that first terminal equipment can be as shown in Figure 2 A is set It is standby, for convenience of describing, in following introduction, it is illustrated so that the first terminal equipment is UE1 as an example.First data can be with It is D2D business datum, is also possible to V2X business datum, which can be periodic business datum, be also possible to non- Periodic business datum, such as bursty traffic data etc., this is not restricted.For convenience of description, in the following description, It will be illustrated so that the first data are paroxysmal V2X business datum as an example.

When UE1 needs to send paroxysmal V2X business datum, then UE1 is paroxysmal for sending this firstly the need of determination The first resource of V2X business datum.

In a kind of possible embodiment, when UE1 is linked into base station, base station can be distributed for UE1 for sending V2X business The resource pool of data, the resource pool are the set of multiple running time-frequency resources, and UE1 can be used the resource in the resource pool and carry out V2X Business datum sends and receives.Certainly, which is also possible to pre-configuration, and this is not restricted.The resource pool can be with Shown in Fig. 6 A, a certain section of fixed frequency domain resource, such as subcarrier 0- subcarrier 23 are occupied on frequency domain, occupies certain in the time domain One section of time-domain resource, such as subframe 0- subframe 100, certainly since a subframe is 1ms, accordingly it is also possible to be come as unit of ms The time-domain resource for describing resource pool occupancy, for example, 0ms-100ms, is either also possible to time slot, mini-slot or symbol etc. It is described for unit, for convenience of description, in the following description, the time domain money occupied to the resource pool is carried out as unit of subframe Source is illustrated.When UE1 needs to send paroxysmal V2X business datum, then first resource is selected from the resource pool.

A kind of possible embodiment, base station may be that UE1 distributes two resource pools, respectively first resource pond and the Two resource pools, certainly, the first resource pond and the Secondary resource pond are also possible to pre-configuration, and this is not restricted.Wherein, One resource pool sends V2X business datum to other UE for UE1, and Secondary resource pond receives V2X business number from other UE for UE1 According to the V2X business datum includes periodic V2X business datum and acyclic V2X business datum.The first resource pond and Secondary resource pond can occupy a certain section of fixed frequency domain resource, such as subcarrier 0- subcarrier for shown in Fig. 6 B on frequency domain 23, occupy two sections of time-domain resources, such as subframe 0- subframe 40 and subframe 60- subframe 100 respectively in the time domain, wherein by son The collection for the running time-frequency resource that carrier wave 0- subcarrier 23 and subframe 0- subframe 40 are constituted is combined into first resource pond, is carried by subcarrier 0- The collection for the running time-frequency resource that wave 23 and subframe 60- subframe 100 are constituted is combined into Secondary resource pond, in this way, when UE1 needs to send burst When the V2X business datum of property, then first resource is selected from first resource pond.

It should be noted that first resource pond is also possible to the resource pool with other purposes, for example, the first resource pond It can be the resource pool for sending dispatching distribution (scheduling assignment, SA), or for sending other business The resource pool etc. of data, does not limit first resource pond herein.

Certainly, the first resource pond and the Secondary resource pond can also occupy identical time-domain resource and occupy difference respectively Frequency domain resource, as shown in Figure 6 C, which is made of subcarrier 0- subcarrier 11 and subframe 0- subframe 100 The set of running time-frequency resource, the Secondary resource pond are the time-frequency money being made of subcarrier 12- subcarrier 23 and subframe 0- subframe 100 The set in source.

In a kind of possible embodiment, when UE1 is linked into base station, base station can be distributed for UE1 for sending and receiving The first resource pond of periodic business datum, and the Secondary resource for sending and receiving acyclic business datum Pond, the first resource pond and Secondary resource pond are also possible to UE1 pre-configuration, when UE1 needs to send paroxysmal V2X business number According to when, then select first resource from Secondary resource pond.Wherein, first resource pond and Secondary resource pond can be such as Fig. 6 B- Fig. 6 C Shown, details are not described herein.

It should be noted that resource pool shown in Fig. 6 A- Fig. 6 C is only a kind of example, when which is also possible to other Frequency resource, this is not restricted.In addition, resource pool shown in Fig. 6 A- Fig. 6 C can also repeat with the period a length of when some It is existing.For example, the period can be 500 subframes, then there is the resource as shown in Fig. 6 A or Fig. 6 B or Fig. 6 C in every 500 subframes Pond.

Specifically, it when UE1 selects the resource for sending paroxysmal V2X business datum from resource pool, can adopt With any one in following three kinds of selection modes.Three kinds of selection modes are as follows:

The first selection mode:

UE1 determines the time domain scale for listening to window for listening to first, and the resource selection window for selecting resource Time domain scale.

1) time domain scale of resource selection window is determined.

A) upper bound of resource selection window is determined.

A kind of possible embodiment, UE1 is determined in subframe n sends the paroxysmal V2X business datum, for example, the son At the time of the communication module that frame n can be the physical layer positioned at UE1 receives the business datum issued by the high level of UE1, then, UE1 can be according to the delay requirement of the paroxysmal V2X business datum, to determine the upper bound of resource selection window.For example, if this is prominent The delay requirement of the V2X business datum of hair property is x subframe, then the upper bound of resource selection window can be determined as subframe (n+ by UE1 X) at time domain end position, as shown in Figure 7 A.

A kind of possible embodiment, the subsequent resource gravity treatment that may be triggered of UE1, for example, UE1 selection sends the V2X The resource of business datum, still, before not sending the V2X business datum by the resource, UE1 determines the resource by other UE It occupies, then UE1 needs gravity treatment resource, in this case, if the upper bound of resource selection window is determined as subframe (n+x) by UE1 Time domain end position at, and UE1 selection the resource close to the upper bound of resource selection window, such as the resource time domain start bit It is set at subframe (n+x-2), then when UE1 needs gravity treatment resource, UE1 can only select resource from time window [n+x-1, n+x] Time-domain position, it is seen then that for UE1 when carrying out resource gravity treatment, the range of optional time-domain position is smaller, or even in the range may be used The resource time-domain position of the delay requirement of the paroxysmal V2X business datum can not met, in consideration of it, UE1 is prominent according to this When the delay requirement of the V2X business datum of hair property determines the upper bound of resource selection window, the upper bound of resource selection window can be determined At time domain end position for subframe (n+T3), wherein T3 < x, as shown in Figure 7 B.In this way, by the upper bound of resource selection window and son Some surpluses are reserved between frame (n+x), it, can be also sharp by the corresponding running time-frequency resource of the surplus when UE1 is when carrying out resource gravity treatment With for the running time-frequency resource of resource gravity treatment is more, it is easier to meet the time delay need of the paroxysmal V2X business datum It asks, thereby may be ensured that the success rate of resource gravity treatment.

B) lower bound of resource selection window is determined.

The lower bound of the first possible embodiment, resource selection window can be with resource in the prior art shown in Fig. 4 Select window lower bound it is identical, for example, the lower bound of resource selection window be subframe (n+T1) time domain end position, T1 be more than or equal to Zero and be less than or equal to 4 any one integer, as shown in Figure 7 A.

In second of possible embodiment, UE1, can after determining the first resource for sending the V2X business datum The first instruction information can be sent before the first resource, other UE first resource quilt is notified by the first instruction information UE1 is occupied, it is assumed that sends the time between the time-domain position of the first instruction information and the time-domain position where the first resource Between be divided into z subframe, then UE1, which is determined, needs to send the paroxysmal V2X business datum in the time domain original position of subframe n, UE1 can send the first instruction information before the time domain end position of subframe n earliest, and send the first instruction information Time interval between time-domain position and the time-domain position of the first resource of the first instruction information instruction is z subframe, therefore, UE1 can use resource, and earliest time-domain position is at subframe (n+z), so that the lower bound of resource selection window is determined as in the time domain The time domain initial position of subframe (n+z), as shown in Figure 7 B.

It should be noted that if the time-domain position and the time-domain position where the first resource that send the first instruction information Between time interval be fixed value, then z subframe is the fixed value；If send this first instruction information time-domain position with The not instead of fixed value of the time interval between time-domain position where the first resource, with other factors, such as should The difference of paroxysmal V2X business datum or the ability of UE1 are different, and change, then the z subframe is all possible The value of the smallest time interval in time interval.

In the third possible embodiment, by the lower bound of the resource selection window in the first possible embodiment and The lower bound of resource selection window in two kinds of possible embodiments combines, that is, UE1 determines that the lower bound of resource selection window is subframe (n+T1+z) time domain initial position, as seen in figure 7 c.Wherein, UE1 can be in the corresponding time-domain resource of subframe n- subframe T1 The paroxysmal V2X business datum is handled or prepared, for example, the paroxysmal V2X business datum is encoded, Processing such as modulation etc..

2) time domain scale for listening to window is determined.

A) upper bound for listening to window is determined.

The first possible embodiment, the upper bound for listening to window can be with window in the prior art of listening to shown in Fig. 4 The upper bound is identical, such as can be the time domain initial position of subframe (n-1), as shown in Figure 7 A.

Second of possible embodiment can will detect in order to more accurately determine the occupied resource of other UE The upper bound overheard outside bridal chamber is adjusted to the time domain original position of subframe n, as shown in Figure 7 B, in this way, if other UE are true in subframe (n-1) When having determined occupancy resource, UE1 can also be listened to.

B) lower bound for listening to window is determined.

The first possible embodiment, the lower bound for listening to window can be with window in the prior art of listening to shown in Fig. 4 Lower bound is identical, such as can be the time domain initial position of subframe (n-1000), as shown in Figure 7 A.

Second of possible embodiment, the lower bound for listening to window can be determined according to the lower bound of resource selection window.Specifically For, by taking the lower bound of resource selection window is the time domain initial position of subframe (n+T4) as an example, wherein T4 1) in any one money Source selects the value of the lower bound of window, other terminal devices, such as second terminal equipment, by taking second terminal equipment is UE2 as an example, After determining the occupancy resource, second indication information may be sent before the occupancy resource, it is logical by the second indication information Know the UE in addition to UE2, it is assumed that send between the time-domain position of the second indication information and the time-domain position where the occupancy resource Time interval be y subframe, if UE2 will use UE1 determination resource selection window in resource, the occupancy resource is in time domain Upper earliest time-domain position is subframe (n+T4), thus, which can send out earliest in the time domain initial position of subframe (n+T4-y) The second indication information is given, the second indication information sent before the time domain initial position of subframe (n+T4-y) is providing UE1 Carrying out resource selection in source selection window does not influence, and therefore, the lower bound for listening to window can be determined as subframe (n+T4-y) by UE1 Time domain initial position, as shown in Figure 7 B.In this way, can reduce listen to window window it is long, can reduce the duration that UE1 is listened to And can reduce UE1 and determine time delay for sending the resource of the paroxysmal V2X business datum, UE1 can also be reduced to detecing Complexity when intercepted result in overhearing outside bridal chamber is handled.

It should be noted that the value of y to it is aforementioned b) in second of possible embodiment in the value of z it is similar, That is y can be a fixed value, if y is fixed value, y=z；Y can also be the changed value of meeting as z, should Changed factor is identical as z, but when y is a changed value, y is the maximum in all possible time interval Time interval value.

In addition, it is necessary to explanation, in the specific implementation process, the resource selection window upper bound and lower bound can be according to practical need Two kinds in the aforementioned a variety of situations of selection are asked to be combined, the upper bound and lower bound for listening to window can also use identical processing side Formula, and it is not limited to situation shown in Fig. 7 A- Fig. 7 C.

After UE1, which is determined, listens to the time domain scale of window and resource selection window, UE1 can then use side as shown in Figure 3 Formula, then by listening to the information for being located at and listening in window, to select the first resource from resource selection window.Specific implementation process with Fig. 3 is identical, and details are not described herein.

Second of selection mode:

UE1 determines the time domain scale for listening to window for listening to first, and the resource selection window for selecting resource Time domain scale.Specific implementation process is identical with first way, and details are not described herein.

In the second way, when any one UE, which occupies resource, sends business datum, which can provide in the occupancy Instruction information is sent before source, which is used to indicate the occupancy resource, so that other UE be made to receive the instruction information Afterwards, business datum can be sent without using the occupancy resource.

The instruction information is introduced below.

The running time-frequency resource in dedicated resource pool can be used in the instruction information, which can be each UE In access base station, by base station be that each UE is distributed or the dedicated resource pool is what each UE was pre-configured, such as Fig. 8 A institute Show, the resource that instruction information occupies in dedicated resource pool is sent, which indicates for sending and/or receiving industry Some running time-frequency resource in the resource pool for data of being engaged in is occupied, and the dedicated resource pool is in the time domain and for sending and/or connecing The resource pool for receiving business datum occupies identical time-domain resource, and different frequency domain resources is occupied on frequency domain；The instruction information The running time-frequency resource in the resource pool for sending and/or receiving business datum can be used, as shown in Figure 8 B, the instruction information with The occupancy resource is using the running time-frequency resource in the resource pool for sending and/or receiving business datum, certainly, the instruction information Also other running time-frequency resources can be used, this is not restricted.

When the running time-frequency resource in the instruction information and the same resource pool of occupancy resource occupation, the instruction information with should Occupy resource can be used identical frequency domain resource on frequency domain, as shown in Figure 8 C or the instruction information and the occupancy The identical frequency domain resource in part can be used in resource on frequency domain, as in fig. 8d.

It, can be for sending and/or each of the resource pool for receiving business datum in a kind of possible embodiment It is configured to send the running time-frequency resource of the instruction information on time domain unit.The time domain unit can for subframe, time slot or symbol etc., This is not restricted.In following introduction, it will be illustrated so that the time domain unit is subframe as an example.

As shown in Figure 9 A, 2 can be reserved in each subframe for sending the running time-frequency resource of the instruction information, for example, Each running time-frequency resource for sending the instruction information occupies the corresponding time-domain resource of 2 symbols in the subframe in the time domain, Entire frequency domain resource is occupied on frequency domain, which can be orthogonal frequency division multiplex OFDM symbol, naturally it is also possible to other symbols, The number for the symbol that each running time-frequency resource for sending the instruction information occupies in the time domain may be other numerical value, herein With no restriction.In this case, identical frequency domain can be used on frequency domain and provide for the instruction information and the occupancy resource Source.

As shown in Figure 9 B, 4 can be reserved in each subframe for sending the running time-frequency resources of the instruction information, this 4 Running time-frequency resource occupies identical symbol in the time domain, such as occupies the corresponding time-domain resource of 2 symbols of the subframe, at this 4 Frequency resource occupies different frequency domain resources on frequency domain, for example, the entire frequency domain resource that resource pool occupies is divided into 4 differences Frequency domain resource, then each frequency domain resource one corresponding with the corresponding time-domain resource of 2 symbols for sending the instruction information Running time-frequency resource.It is of course also possible to which the entire frequency domain resource that resource pool occupies is divided into N number of different frequency domain resource, N is big In the integer for being equal to 2, this is not restricted.

As shown in Figure 9 C, 2 can be reserved in the time-domain resource of each subframe for sending the time domain of the instruction information Resource, each time-domain resource occupies 2 symbols, and the entire frequency domain resource that resource pool occupies is divided into 4 different frequency domains Resource, then each running time-frequency resource for sending the instruction information occupies 2 symbols in the time domain, and entire frequency is occupied on frequency domain A part of domain resource.

It should be noted that when using being configured to send the running time-frequency resource of the instruction information in each subframe, it can It is identical for sending the running time-frequency resource of the instruction information to configure in each subframe, for example, configuring one in each subframe A for sending the running time-frequency resource of the instruction information, the running time-frequency resource occupies last 2 symbols of the subframe in the time domain, in frequency Entire frequency domain resource is occupied on domain；The different time-frequency money for sending the instruction information can also be configured in each subframe Source configures 3 for sending out for example, configuring 2 in subframe n for sending the running time-frequency resource of the instruction information in subframe n+1 The running time-frequency resource of the instruction information is given, or the corresponding running time-frequency resource of some subframe is all configured for send instruction letter The running time-frequency resource of breath, this is not restricted, so as to increase the flexibility that resource uses.

In addition, it is necessary to explanation, it can be between the time-domain position of the instruction information and the time-domain position of the occupancy resource It is binding relationship.As shown in Figure 10,2 are configured in each subframe for sending the running time-frequency resource of the instruction information, wherein the One time-domain resource for sending the time-frequency resource indication of the instruction information occupancy resource is the after the time-domain resource One subframe, when second time-domain resource for sending the time-frequency resource indication of the instruction information occupancy resource is positioned at this Second subframe after the resource of domain, and the resource for being used to send business datum occupies the entire frequency domain resource of resource pool on frequency domain. In this way, when UE can determine the occupancy resource of the UE of the transmission instruction information according to the time-domain resource for receiving the instruction information.

Both the time-domain position of the instruction information and the time-domain position of the occupancy resource are also possible to unbundling relationship, i.e., Be it is independent, i.e., after UE receives the instruction information, only according to the time-domain position of the instruction information can not determine that sending this refers to Show the occupancy resource of the UE of information.In this case, UE needs the time-domain position and instruction information in conjunction with the instruction information The content of middle instruction determines the time-domain position of the occupancy resource.

Since the time-domain position of the instruction information is associated with the time-domain position of the occupancy resource, when any one UE determines that the UE also needs to determine that this refers to according to the time-domain position of the occupancy resource when sending business datum using the occupancy resource Show the time-domain position of information.In the embodiment of the present application, after the UE determines the occupancy resource, then the business that sends as needed Data determine a time interval, then determine the instruction information according to the time-domain position of the occupancy resource and the time interval Time-domain position.It is below UE3 with any one UE, the time-domain position for the occupancy resource that UE3 is determined is son for convenience of description Frame (n+k), the instruction information indicate to be illustrated for information for the 4th, wherein k is positive integer.

In the embodiment of the present application, UE3 needs the business datum sent according to the time-domain position and UE3 of the occupancy resource Determine that the method for the time-domain position of the 4th instruction information can be using any one in following three kinds of modes, three kinds of modes are such as Under:

First way:

After UE3 determines that the time-domain position of the occupancy resource is subframe (n+k), then the business that sends is needed according to the UE3 The priority of data determines a time interval, and subframe (n+k) is subtracted the corresponding time-domain position of the time interval as the 4th Indicate the time-domain position of information.

Specifically, priority can be divided into multiple ranks, for example, can be divided into high, medium and low three ranks, UE3 can be with The information such as delay requirement, the size of the business datum sent as needed determine the priority-level of business datum, for example, with For the delay requirement for the business datum that UE3 is sent as needed determines priority-level, the delay requirement of business datum is taken Value is lower than the first default time delay value, it is determined that the priority-level of the business datum is height；The delay requirement of business datum takes Value is between the first default time delay value and the second default time delay value, it is determined that during the priority-level of the business datum is； The value of the delay requirement of business datum is higher than the second default time delay value, it is determined that the priority-level of the business datum is It is low.It is of course also possible to use other information determines priority-level, specific method of determination with priority is determined according to delay requirement Grade is identical otherwise, and therefore not to repeat here.After UE3 determines the priority-level for needing the business datum sent, then basis The priority of storage and the corresponding relationship of time interval determine time interval corresponding with the business datum.The priority and when Between the corresponding relationship that is spaced can be one-to-one relationship, i.e., a kind of priority corresponds to a kind of time interval, is also possible to a pair More relationships, i.e., a kind of priority correspond to a variety of time intervals, are also possible to many-to-one relationship, i.e. multiple priorities are corresponding same A kind of time interval.The corresponding relationship can be by base station configuration, is also possible to be pre-configured to be on each UE, certainly may be used Using as changeless parameter a set of in communication protocol, or as the common configuration parameter of cell level, i.e., different is small Area can configure different corresponding relationships, alternatively, can also be used as the configuration parameter of resource pool rank, for example, sending the instruction The resource pool of information may be dedicated resource pool dedicated for sending the instruction information or for sending and/or receiving industry The resource pool for data of being engaged in then can configure different corresponding relationships for different resource pools, and this is not restricted.

The priority-level of business datum for needing to send is determined for height, and according to priority and time interval with UE3 The time interval that corresponding relationship determines is s subframe, and s is positive integer, so that it is determined that going out to send the time-domain position of the instruction information For subframe (n+k-s).

The second way:

After UE3 determines that the time-domain position of the occupancy resource is subframe (n+k), then the business that sends is needed according to the UE3 The type of data determines a time interval, and subframe (n+k) is subtracted the corresponding time-domain position of the time interval as the 4th and is referred to Show the time-domain position of information.

Specifically, the type of business datum can be divided into video type, audio types, image type and text class Type, it is of course also possible to be divided into other types, this is not restricted.After UE3 determines the type for needing the business datum sent, Then according to the corresponding relationship of the type of storage and time interval, time interval corresponding with the business datum is determined.The type with The corresponding relationship of time interval can be one-to-one relationship, i.e. a seed type corresponds to a kind of time interval, be also possible to a pair More relationships, i.e. a seed type correspond to a variety of time intervals, are also possible to many-to-one relationship, i.e. multiple types correspond to same Time interval.The configuration mode of the corresponding relationship is identical with first way, and details are not described herein.

Using the determining type for needing the business datum sent of UE3 as video type, and according to pair of type and time interval It should be related to that determining time interval is s subframe, s is positive integer, so that it is determined that the time-domain position for going out to send the instruction information is Subframe (n+k-s).

The third mode:

After UE3 determines that the time-domain position of the occupancy resource is subframe (n+k), then the business that sends is needed according to the UE3 The priority and type of data determine a time interval, and subframe (n+k) is subtracted the corresponding time-domain position of the time interval and is made For the time-domain position of the 4th instruction information.

Specifically, the priority-level of business datum and type respectively with phase in first way and the second way Together, details are not described herein.After UE3 determines the priority-level and type that need the business datum sent, then according to storage Priority, the corresponding relationship between type and time interval three, determine time interval corresponding with the business datum.This is excellent Corresponding relationship between first grade, type and time interval three can be one-to-one relationship, i.e., a kind of priority and one kind Type corresponds to a kind of time interval, that is to say, that the different identical business datums of priority-level but type corresponds to different Time interval or different types but the identical business datum of priority-level corresponds to different time intervals；The priority, Corresponding relationship between type and time interval three is also possible to one-to-many relationship, i.e., a kind of priority and a seed type Corresponding a variety of time intervals, it is of course also possible to be many-to-one relationship, i.e. different priorities and different type correspond to same Time interval.

Certainly, UE3 determines the time corresponding with the business datum according to the priority-level and type of business datum Interval can also use other modes, for example, UE3 respectively according to the first corresponding relationship of priority and time interval, determines the One time interval determines the second time interval then according to the second corresponding relationship of type and time interval, then from first when Between interval and the second time interval in determine the larger value be time interval corresponding with the business datum, it is of course also possible to determination Smaller value in first time interval and the second time interval is time interval corresponding with the business datum, is not limited herein System.

It should be noted that the configuration mode of the corresponding relationship is identical with first way, details are not described herein.

Determine that the priority and type according to the business datum, determining time interval are s subframe with UE3, s is positive whole Number, so that it is determined that the time-domain position for going out to send the instruction information is subframe (n+k-s).

It should be noted that sending the resource and the time interval of occupancy resource in the time domain and preferential of the instruction information The relationship of grade can have following three kinds of situations, specific as follows:

The first situation:

Priority is higher, then resource and the time interval of occupancy resource in the time domain for sending the instruction information are longer, As shown in Figure 11 A- Figure 11 D, in this way, time interval is longer, then the instruction information can be sent as early as possible, so as to Increase the paroxysmal V2X business datum to obtain the probability of send opportunity and increase the success rate of preempting resources.

In Figure 11 A, the resource for sending the instruction information is located in dedicated resource pool, in Figure 11 B- Figure 11 D, sends The resource of the instruction information and the occupancy resource are located in identical resource pool.Wherein, it in Figure 11 A or Figure 11 B, sends this and refers to The frequency domain position of the resource and the occupancy resource of showing information can be UE1 pre-configuration, be also possible to UE1 from corresponding resource pool Middle random selection, it is of course also possible to use other modes determine the frequency domain position of the first resource Yu the Secondary resource, herein not It is restricted.In Figure 11 C- Figure 11 D, first resource occupies entire frequency domain resource on frequency domain, and in each subframe of resource pool In configured with send the instruction information resource, the resource of the transmission instruction information can be with the occupancy resource occupation part phase With frequency domain resource, as shown in Figure 11 C, can also with the identical frequency domain resource of occupancy resource occupation, such as Figure 11 D institute Show.

Second situation:

Priority is higher, then resource and the time interval of occupancy resource in the time domain for sending the instruction information are shorter, As shown in Figure 12 A- Figure 12 D.In this way, the time interval is shorter, then sends the instruction information and send the paroxysmal V2X business Time interval between data is shorter, can provide lower time delay.

In fig. 12, the resource for sending the instruction information is located in dedicated resource pool, in Figure 12 B- Figure 12 D, sends The resource of the instruction information and the occupancy resource are located in identical resource pool.Wherein, it in Figure 12 A- Figure 12 D, sends this and refers to The frequency domain position of the resource and the occupancy resource of showing information is identical as the first situation, and details are not described herein.

The third situation:

Priority and the resource and the time interval of occupancy resource in the time domain that send the instruction information be not directly proportional Or inverse relation.In the corresponding relationship of the priority and time interval, it can be configured at random for each priority corresponding Time interval, when the corresponding relationship of the priority and time interval is one-to-one correspondence or many-to-one relationship, every kind preferential Grade is only capable of using the time interval indicated in corresponding relationship, when the corresponding relationship of the priority and time interval is one-to-many When relationship, after determining priority, then a time interval can be randomly choosed from multiple time intervals.In this way, UE can be with Randomly choose time interval in available time interval set, and the identical probability of the randomly selected time interval of different UE It is lower, even if then when different UE sends the business datum with equal priority, between the time selected due to different UE Every difference, so as to so as to which the instruction information of the transmission of other side, professional etiquette of going forward side by side can be listened between the different UE mutually It keeps away, further increases transmission reliability.

In addition, it is necessary to explanation, UE3 can also use other according to determining time interval corresponding with the business datum Mode, this is not restricted.For example, UE3 can determine time interval according to the ability information of UE3, in this case, when When the ability information of UE3 does not change, no matter UE3 sends any business datum, and time interval will not all change, In, aforementioned first way can refer to the third mode according to the method that ability information determines time interval, no longer go to live in the household of one's in-laws on getting married herein It states.

After UE3 is determined for sending the instruction information corresponding time-domain position, it is also necessary to further determine that the instruction is believed The content of breath.In the embodiment of the present application, the content of the instruction information may include any one in following a variety of situations, should A variety of situations are as follows:

The first situation:

It only needs to include occupancy resource length in the time domain and the business datum that needs are sent in the instruction information Priority.For example, the occupancy resource uses entire frequency domain resource on frequency domain, and the occupancy resource and the instruction information are in time domain On when having binding relationship, may include above content in the instruction information.

Further, when between the instruction information and the occupancy resource time interval and priority be one-to-one relationship or When the many-to-one corresponding relationship of person, the UE for receiving the instruction information can be provided according to the time-domain position of the instruction information and the occupancy The binding relationship of the time-domain position in source determines time interval between the two, for example, UE1 receives UE3 hair at subframe (n+k-s) The instruction information sent, UE1 be stored in advance it is each for send the instruction information resource time-domain position and occupy resource when Binding relationship between the position of domain, for example, when the time-domain position for indicating information is subframe (n+k-s), instruction information instruction Occupancy resource time-domain position be subframe (n+k-s+3), i.e., between the instruction information and the time-domain position of the occupancy resource Time interval be 3 subframes, then according between the instruction information and the occupancy resource time interval and priority one by one Corresponding relationship or many-to-one corresponding relationship, with the time interval and priority between the instruction information and the occupancy resource Corresponding relationship is to be illustrated for one-to-one relationship, which can be with are as follows: when time interval is 3 subframes When, corresponding priority-level is height；When 2 subframes of time interval, during corresponding priority-level is；When time interval is When 1 subframe, corresponding priority-level be it is low, according to the corresponding relationship determine time interval be 3 subframes priority grade Wei not be high, and then it can be informed in the priority of the business datum sent in the occupancy resource, therefore, in this case, industry The priority for data of being engaged in can also be without instruction.And when the time interval between the instruction information and the occupancy resource and preferentially When grade is one-to-many corresponding relationship, then need to indicate priority in the instruction information.

Second situation:

Needed in the instruction information include occupancy resource length in the time domain, the business datum for needing to send it is preferential The time domain initial position of grade and the occupancy resource.For example, the occupancy resource uses entire frequency domain resource on frequency domain, and this is accounted for With resource and the instruction information in the time domain without binding relationship when, may include above content in the instruction information.Wherein, this is accounted for It can be the position of first subframe of the occupancy resource, or the instruction information with the time domain initial position of resource Time interval between time-domain position and the time-domain position of the occupancy resource.

Further, when between the instruction information and the occupancy resource time interval and priority be one-to-one relationship Or when many-to-one corresponding relationship, in the instruction information can only the priority comprising business datum and the occupancy resource when Any one in the initial position of domain；And when the time interval between the instruction information and the occupancy resource is with priority When one-to-many corresponding relationship, then need to indicate the priority of the business datum and the time domain of the occupancy resource in the instruction information Initial position.

The third situation:

It further include the frequency of the occupancy resource on the basis of the first aforementioned situation or second situation, in the instruction information Domain position.For example, entire frequency domain resource is not used in the occupancy resource, for example, the occupancy resource of difference UE is located at different frequency domains In resource, then in the instruction information also include the occupancy resource frequency domain position, such as the occupancy resource frequency domain initial position, The length etc. of the frequency domain resource of the occupancy resource occupation.

4th kind of situation:

On the basis of the first aforementioned situation or second situation or the third situation, further include in the instruction information Including some information in dispatching distribution (scheduling assignment, SA), for example, comprising modulation coding scheme, this accounts for At least one of information such as the time interval with the period of resource, twice between business data transmission.

5th kind of situation:

It further include expecting to use the occupancy on the basis of the first aforementioned situation to the 4th kind of situation, in the instruction information The number of resource.For example, UE3 can be estimated in advance will use the number of the occupancy resource, then it can in the instruction information To indicate the number, so that the available UE3 of other UE more occupies the information of resource, and then this can be accounted for Hidden with resource, is conducive to promote transmission reliability.

It certainly, can also include other content in the instruction information, this is not restricted.

After UE3 determines the content in the instruction information, then the instruction information is sent in determining resource.For example, The 4th instruction information is sent in subframe (n+k-s).

To which when subframe (n+k-s) is located in the time domain scale for listening to window that UE1 is determined, UE1 just receives the 4th instruction Information.As shown in figure 13, UE1 includes by the time-domain position for receiving the 4th instruction information and/or the 4th instruction information Content, determines the time-domain position for occupying resource corresponding with the instruction information, and specific determination method is referred to aforementioned refer to this Show the introduction in the content of information, details are not described herein.To which UE1 determines that a certain resource in resource selection window is occupied, then UE1 selects a resource for sending the paroxysmal V2X business datum, the choosing from other resources in the resource selection window The resource selected is the first resource.

The third selection mode:

The first resource that UE1 is determined can be the resource after carrying out resource gravity treatment, i.e., before step 501, the application is real The method in example is applied also it needs to be determined that carrying out resource gravity treatment.Figure 14 is please referred to, for the flow chart for carrying out resource gravity treatment, the flow chart Be described as follows:

Step 1401, UE1 determine information resources, and the information resources are for sending first data.

Step 1401 is identical as step 501, and details are not described herein.

Step 1402, UE2 send second indication information, and UE1 receives second indication information.

In the embodiment of the present application, which is used to indicate UE2 and occupies the information resources the second data of transmission, UE2 sends the process of second indication information and the UE3 in step 501 sends the 4th and indicates that information is identical, and details are not described herein.

The process that UE1 receives second indication information can receive UE3 hair with UE1 in second of selection mode of step 501 The 4th instruction information sent is identical, can also be received using any one in following three kinds of reception modes, this three kinds connect Debit's formula is as follows:

The first receives mode:

After UE1 determines the information resources, the 4th finger can be determined using UE3 in second of selection mode of step 501 Show the method for the time-domain position of information, determine the time-domain position of the 4th resource for sending third instruction information, which refers to Show that information is used to indicate the position of the information resources, details are not described herein.

When determining four resources using the priority of the paroxysmal V2X business datum with UE1, and between the time used Every with the relationship of priority be the first situation above-mentioned, that is, the more high then time interval of priority is longer, then UE1 is not sent In time domain scale before third instruction information, continue the instruction information for listening to other UE transmission.That is, UE1 is by listening to One time window receives the second indication information, and the time domain end position of the first time window is that the time domain of the 4th resource originates Position, the time domain initial position of the first time window are after UE1 determines the information resources, as shown in fig. 15.

Second of reception mode:

When determining four resources using the priority of the paroxysmal V2X business datum with UE1, and between the time used Every with the relationship of priority be second situation above-mentioned, that is, the more high then time interval of priority is shorter, then UE1 send should Third indicates that information in using the time domain scale before the information resources the first data of transmission, continues to listen to other UE hair later The instruction information sent.That is, UE1 receives the second indication information by listening to the second time window, the time domain of second time window Initial position is the time domain end position of the 4th resource, and time domain end position is the time domain initial position of the information resources, such as Shown in Figure 15 B.

The third receives mode:

When determining four resources using the priority of the paroxysmal V2X business datum with UE1, and between the time used Every with the relationship of priority be the third situation above-mentioned, that is, priority does not have directly proportional or inverse relation to time interval, Then UE1 the not sent third indicate information before time domain scale, and send the third instruction information after to using should In time domain scale before information resources the first data of transmission, continue the instruction information for listening to other UE transmission.That is, UE1 passes through First time window and the second time window are listened to receive the second indication information, the time domain end position of the first time window is should The time domain initial position of 4th resource, the time domain initial position of the first time window are after UE1 determines the information resources, this second The time domain initial position of time window is the time domain end position of the 4th resource, and time domain end position is the time domain of the information resources Initial position, as shown in figure 15 c.

Step 1403, UE1 determine that the information resources are occupied according to the second indication information.

After UE1 receives the second indication information, can directly by the time-domain position of the second indication information and/or Content in the second indication information determines that the second indication information indicates the information resources, specific method of determination and step 501 Second of selection mode in corresponding contents it is identical, details are not described herein.In the embodiment of the present application, UE1 determines the third Any one occupied that can have in following three kinds of methods of determination of resource, three kinds of methods of determination are as follows:

The first method of determination:

After UE1 determines that the second indication information indicates the information resources, then it is occupied to directly determine the information resources.

Second of method of determination:

After UE1 determines that the second indication information indicates the information resources, the second indication information and/or reception can be passed through The time-domain position of the second indication information obtains the priority of UE2 the second data to be sent.If the priority of second data Be higher than or optionally greater than first data priority, for example, the priority of the second data is height, the priority of the first data is In, then UE1 determines that the information resources are occupied.

The third method of determination:

After UE1 determines that the second indication information indicates the information resources, the second indication information and/or reception can be passed through The time-domain position of the second indication information obtains the priority of UE2 the second data to be sent.If the priority of second data It is higher than or optionally greater than a pre-set priority, for example, during the pre-set priority can be, if the priority of the second data is height Or when middle, then UE1 determines that the information resources are occupied.

When UE1 determines that the information resources are occupied, then UE1 determination needs to carry out resource gravity treatment, i.e. execution step 501, really Determine first resource.

In a kind of possible embodiment, UE1 determines the first resource in the first subset for determining resource selection window, should The time domain initial position of first subset be the second indication information occupy resource time domain end position, first subset when There are two types of situations for domain end position.The first situation, the time domain end position of first subset are the resource selection that UE1 is determined The corresponding time domain end position in the upper bound of window, as shown in Figure 16 A；Second situation, if the upper bound for the resource selection window that UE1 is determined There are surplus between the maximum time-domain position for the delay requirement for meeting first data in the time domain, then the first subset when Domain end position can be the time domain stop bits for meeting the maximum time-domain position of delay requirement of first data in the time domain Set, for example, the maximum time-domain position be subframe (n+x), then the time domain end position of first subset be subframe (n+x) when Domain end position, as shown in fig 16b.

UE1 is corresponding from second of the selection mode of method and step 501 for determining first resource in first subset Content is identical, and details are not described herein.

It should be noted that if when UE1 determines the first resource using the third selection mode, due to the model of the first subset The delay requirement that may be unable to satisfy first data is enclosed, therefore, UE1 possibly can not choose the first resource, in this feelings Under condition, UE1 can directly abandon first data.In the following description, will by taking UE1 successfully determines the first resource as an example into Row explanation.

Step 502, UE1 determine time interval according to the paroxysmal V2X business datum.

In the embodiment of the present application, since there are many selection modes of step 501, then UE1 determines the mode of time interval Also not identical.

First way:

When UE1 uses the first selection mode or second of selection mode in step 501 to determine the first resource, UE1 determines that the mode of the time interval is identical as the corresponding contents in second of selection mode in step 501, no longer superfluous herein It states.

The second way:

After UE1 determines the first resource using the third selection mode in step 501, UE1 is between determining the time Every before, the priority of the paroxysmal V2X business datum can be first improved.For example, the paroxysmal V2X business datum is first During beginning priority is, then UE1 can propose the priority of the paroxysmal V2X business datum before determining the time interval It is upgraded to high priority.

After UE1 promotes the priority of the paroxysmal V2X business datum, UE1 is then true according to the priority after the promotion The fixed time interval, specific method of determination is identical as the corresponding contents in second of selection mode in step 501, herein no longer It repeats.

The third mode:

After UE1 determines the first resource using the third selection mode in step 501, UE1 is between determining the time Every when, the first interval, for example, 5 sons are determined according to the priority of the paroxysmal V2X business datum and/or type first Frame, then, UE1 determine that time interval corresponding with the paroxysmal V2X business datum is when increasing to preset on first interval Between be spaced after obtained the second interval, it is preconfigured which can be UE1, such as 3 subframes, then between second It is divided into 8 subframes.

Step 503, UE1 determine Secondary resource according to the first resource and the time interval.

In the embodiment of the present application, which is located in the time domain before the first resource, which is used for Send the first instruction information of the position for indicating the first resource.After UE1 determines the first resource and time interval, then exist The time interval, the as time-domain position of Secondary resource are subtracted on the time-domain position of the first resource.

Step 504, UE1 send the first instruction information on the Secondary resource.

In a kind of possible embodiment, when UE1 determines that the first resource is unoccupied, then sent out on the Secondary resource Give the first instruction information.If UE1 determines that the first resource is occupied before sending the first instruction information on the Secondary resource, Then UE1 needs to repeat the third selection mode in step 501, reselects and sends the paroxysmal V2X business datum Resource, until being successfully transmitted the paroxysmal V2X business datum.It is of course also possible to be to carry out resource weight several times After choosing, when not being successfully transmitted the paroxysmal V2X business datum yet, the paroxysmal V2X business datum is directly abandoned.

It should be noted that UE1 can also be using step when UE1 sends the first instruction information on the Secondary resource Method described in rapid 501 listens to whether the Secondary resource is occupied by other UE by determining window of listening to, however, it is determined that this second When resource is occupied by other UE, UE1 can also be selected using the third selection mode in step 501, gravity treatment first resource with And Secondary resource.Certainly, if UE1 determines that the Secondary resource is occupied by other UE, but the first resource is not occupied by other UE, In this case, UE1 only can also need to redefine the Secondary resource, for example, determining near the Secondary resource Other resources be resource for sending the first instruction information, the first instruction letter is then sent in newly determining resource Breath, it is of course also possible to use other modes are adjusted, this is not restricted.

By the above method, when UE1 needs to send the paroxysmal V2X business datum, the burst can sent first Property V2X business datum before send the first instruction information, and, it is prominent according to this for sending the resource location of the first instruction information Hair property V2X business datum determine, that is, send different data and then correspond to different time intervals, in this way, even if UE and its His UE selects identical resource to send different data, due to the difference for the data to be sent, UE1 is caused to send the first instruction letter The resource location of breath and the resource location that other UE send instruction information are also different, in this way, other UE can be timely received The first instruction information, so that when determining that itself sends the resource of data the first resource can not be selected, so as to keep away Exempt from as selecting identical resource to send the problem that transmission reliability is low caused by data.
