In alternatively possible implementation, the data in data and first resource in reserved resource include burst industry Business data.For example, can be illustrated in case where the time-division by the resource in resource pool, then Figure 14 reserves resource into Figure 17 On data can be burst service data, the data on first resource may include burst service data, as a result respectively as schemed 22 to shown in Figure 25.The situation is commonly available to periodic non-burst business datum such as and has been sent completely, and has at this time reserved Resource, but without under the periodic non-burst business datum scene the to be sent or biggish field of non-burst business datum Under scape, etc., the embodiment of the present application is not especially limited this.

Further, in the embodiment of the present application, in the data and reserved resource on first resource data can for it is whole into The data of row channel coding, or separately carry out the data of channel coding, the embodiment of the present application is not especially limited this.

Wherein, if data can be the whole data for carrying out channel coding in data and reserved resource on first resource, It can also include then that third indicates that information, third instruction information are used to indicate on first resource in SCI or preemption information Data in data and reserved resource are transmission block (transport block, TB) or third instruction information for referring to Show that the data in the data on first resource and reserved resource are that combined coding or third instruction information are used to indicate first The data in data and reserved resource in resource need combined decoding in receiving side.

Alternatively, if data can be the data that separately carry out channel coding in data and reserved resource on first resource, It further include then third instruction information in SCI or preemption information, third instruction information is used to indicate the data on first resource It is that independent TB or third indicate that information is used to indicate the data on first resource and reserved money with the data in reserved resource Data on source are that absolute coding or third instruction information are used to indicate in the data on first resource and reserved resource Data need separately decoding or third instruction information to be used to indicate receiving side and received according to normal mode in receiving side.

For example, a bit indication is added in SCI or preemption information, when being 1, data on first resource and pre- are indicated Staying the data in resource is a TB, or the data in the data and reserved resource on instruction first resource are combined codings , or indicate that the data in the data and reserved resource on first resource need combined decoding in receiving side；When being 0, instruction The data in data and reserved resource on first resource are independent TB, or data and reserved money on instruction first resource Data on source are absolute codings, or the data in the data and reserved resource on instruction first resource are needed in receiving side Separately decoding, or instruction receiving side are received according to normal mode.

Certainly, in the embodiment of the present application, if data are separately to carry out channel in data and reserved resource on first resource The data of coding are separately transmitted on two time quantums as two TB, then can nothing in SCI or preemption information It need to additionally indicate, receiving side communication equipment can be opened according to two independent TB points on two time quantums and carry out reception reconciliation Code, the embodiment of the present application are not especially limited this.

Optionally, in the embodiment of the present application, there is reserved resource just in the first communication equipment, and reserved resource can accommodate In the case where burst service data, burst service data directly can also be sent using reserved resource as shown in Figure 26 to Figure 31, And do not have to additional carry out resource and seize, the transmission delay of burst service data can be further decreased in this way, and the application is implemented Example is not especially limited this.

Wherein, the resource category in Figure 26, Figure 27, Figure 29 and Figure 30, for sending the resource of data and for sending SCI In the same resource pool；In Figure 28 and Figure 31, the resource for sending the resource of data and for sending SCI belongs to different Resource pool, for example, SCI resource pool is for sending SCI；Data resource pond is for sending data.Wherein, in Figure 26 and Figure 27, Resource in resource pool is frequency division, and the resource in Figure 26, for sending the resource of burst service data and for sending SCI It is the time-division, Tu27Zhong, the resource for sending the resource of burst service data and for sending SCI is frequency division；In Figure 29 In Figure 30, the resource in resource pool is the time-division, and in Figure 29, for sending the resource of burst service data and for sending The resource of SCI is the time-division, and Tu30Zhong, the resource for sending the resource of burst service data and for sending SCI is frequency division 's.

Wherein, aforesaid way two is relative to the advantage of mode one: on the one hand, mode two does not need additional for sending out The private resource of preemption information is sent, therefore is reduced resource waste, the utilization rate of resource is improved；On the other hand, due to can be with Using reserved resource send burst service data so that resource using more flexible.

Mode three: Secondary resource is the resource in the resource for sending SCI.

That is, letter is seized in the resource transmission that transmission SCI can be used in the first communication equipment in the embodiment of the present application Breath.For example, SCI resource pool is for sending SCI, in addition, the first communication equipment can also be in the SCI resource pool in Figure 32 Send preemption information.Due to not needing the additional private resource for being used to send preemption information, reduces resource waste, mention The utilization rate of resource is risen.

It should be noted that Figure 32 is carried out by sending the resource of SCI and sending for the resource of preemption information is frequency division Illustrate, certainly, the resource for sending SCI and the resource for sending preemption information are also possible to the time-division, the embodiment of the present application to this not Make specific limit.

For aforesaid way three, since SCI resource pool not only can be used for sending SCI, but also can be used for sending preemption information, Therefore it needs to be distinguish SCI and preemption information.

In a kind of possible implementation, a domain is added in preemption information or SCI for both distinguishing, such as 1 bit, It indicates that the information is SCI when being 0, indicates that the information is preemption information etc. when being 1.

Alternatively, alternatively possible mode, the two uses different scramble sequences, for example, as at the beginning of using different sequences Beginningization ID (c_init), sequence initialization ID indicates that the information is SCI when being ID1, sequence initialization ID indicates the information when being ID2 For preemption information etc..

For aforesaid way one either into mode three formula, optionally, resource distribution in the embodiment of the present application ginseng It can also include a parameter in number, happen suddenly for being characterized in the corresponding resource pool of the resource configuration parameter whether to allow to send Business datum.For example, indicating to allow when being 1 using 1 bit, indicate not allow when being 0.Wherein, in the case where permission, First communication equipment just determines the Secondary resource for sending preemption information；In the case where not allowing, the first communication equipment is true It is scheduled in the corresponding resource pool of the resource configuration parameter and does not send burst service data.Thus it is possible, on the one hand, can be logical to avoid first The problem of believing the burst service data transmission fails of equipment, the reliability of improve data transfer；It on the other hand, can be to avoid first Interference of the data transmission of communication equipment to the data transmission of other communication equipments, improves the matter of other communications device data transmission Amount.

For aforesaid way one either into mode three formula, optionally, in the preemption information in the embodiment of the present application It may include all information in existing SCI, that is to say, that the preemption information can be sent using the format of existing SCI, At this point, when sending data on first resource the corresponding SCI of data can be sent on first resource according to existing mode； SCI can not also be sent on first resource, because having included the SCI in preemption information, the embodiment of the present application does not make this It is specific to limit.Alternatively, optional, the embodiment of the present application can also define the new control information format of one kind and seize letter for sending It ceases, only includes the minimum information of instruction first resource in the preemption information, such as only include the time-domain position of necessary first resource The priority etc. of data on information, the frequency domain position information of first resource or first resource, at this point, being sent on first resource It when data, needs according to existing mode, the corresponding SCI of data is sent on first resource, the embodiment of the present application does not make this It is specific to limit.

Wherein, in the embodiment of the present application step S604:
