[0100]值得注意的是,本发明实施例在频域上调频的传输D2D数据包的多个数据包副本,虽然减小了传输时延,但存在一个潜在问题,即由于数据发送需要占用多个频域资源,有可能导致系统频率资源的不足; [0100] Notably, the plurality of copies of data packets in the frequency domain embodiment of the FM transmission packet D2D embodiment of the present invention, while reducing the transmission delay, but there is a potential problem, since data transmitted requires more than one frequency-domain resources may be insufficient frequency resources system;

[0101]因此本发明实施例可预定义具有传输优先级的D2D数据包(如通过D2D数据包所属的业务类型,或者D2D数据包的具体发出方,接收方等定义D2D数据包的传输优先级),并设置传输优先级所对应的专用频谱资源,从而将具有传输优先级的D2D数据包,分配到为该传输优先级所分配的专用频谱资源中,确定传输频率; [0101] Thus, the present invention may be predefined embodiment has a transmission priority D2D data packets (e.g., service type by D2D packet belongs, or specifically D2D packet originator, transport priority recipient etc. defined D2D packets ), and sets the transmission priority corresponding specific spectrum resources, thereby having a transmission priority D2D data packet, the transmission priority assigned to the dedicated spectrum for the allocated resources, the determined transmission frequency;

[0102]具体的,本发明实施例在确定各数据包副本的传输频率时,可判断所述D2D数据包是否对应有传输优先级;若所述D2D数据包对应有传输优先级,则在为所述D2D数据包对应的传输优先级所分配的专用频谱资源中,确定各数据包副本的传输频率。 [0102] Specifically, embodiments of the present invention, when determining the transmission frequency of each copy of the data packet, can determine whether the packet corresponding to the D2D have a transmission priority; D2D if the packet corresponds with a transmission priority, for the the spectrum resources dedicated transmission priority assigned D2D packet corresponds, determining the transmission frequency of each copy of the packet.

[0105]基于此,对于考虑到时延要求高的V2X(车量对外界的信息交换)业务发送的概率往往较低(如追尾、紧急制动在一个区域内属于小概率事件),因此时延要求高的V2X业务带来的频谱资源“浪费并不严重”;为了更好的解决此问题,本发明实施例考虑根据业务的不同QoS需求为V2X业务分配专用频谱资源; [0105] Based on this, taking into account for the V2X high latency requirement (amount of the vehicle outside the exchange of information) transmitted traffic tends to be lower probability (e.g., rear-end collision, the emergency brake is a small probability events within a region), and therefore when the extension of the high requirements of business brought V2X spectrum resources "waste not serious"; to better solve this problem, for example, consider the allocation of dedicated spectrum resources for V2X services according to different QoS needs of the business practice of the present invention;

[0107]可选的,本发明实施例若确定所述D2D数据包为V2X数据包,则确定所述V2X数据包对应有传输优先级,进而在为V2X数据包所分配的专用频谱资源中,确定各数据包副本的传输频率; [0107] Optionally, embodiments of the present invention, if the data packet is determined as D2D V2X data packet, determining that the data packet corresponds with a V2X transmission priority, and further spectrum resources dedicated to V2X data packet allocation, determining a transmission frequency of each copy of the data packet;

[0109] 可选的,对于普通D2D数据包中高优先级的D2D数据包,本发明实施例也可设置该高优先级的普通D2D数据包具有传输优先级,具有传输优先级的普通D2D数据包可根据实际需要设定; [0109] Alternatively, those of ordinary D2D packet of high priority D2D packets, embodiments of the present invention may also be provided the high-priority general D2D data packet having a transmission priority, having a transmission priority normal D2D packets may be set according to actual needs;

[0110] 具体的,在本发明实施例中,若所述D2D数据包为普通D2D数据包,且所述普通D2D数据包的传输优先级达到预定传输优先级,则确定所述普通D2D数据包对应有传输优先级;进而在为所述普通D2D数据包对应的传输优先级所分配的专用频谱资源中,确定各数据包副本的传输频率。 [0110] Specifically, in the embodiment of the present invention, if the data packet is a normal D2D D2D data packet, and the transmission priority of the normal data packet reaches a predetermined D2D transmission priority, it is determined that the normal packet D2D have the corresponding transmission priority; Further spectrum resources dedicated transmission priority assigned to the normal D2D data packet corresponding to the determined transmission frequency of each copy of the data packet.

[0111]进一步,为D2D数据包对应的传输优先级分配专用频谱资源后,本发明实施例还可以实现不同业务的优先级处理从而更加合理的利用资源,避免多发紧急业务,和低发的非紧急业务之间的资源竞争; [0111] Further, after the transmission priority assigned dedicated spectrum resources D2D data packet corresponding to the embodiment of the present invention may also be implemented priority processing and thus more rational use of resources of different services, to avoid multiple emergency service, and non-low hair competition for resources between emergency services;

[0112]具体的,为所述D2D数据包对应的传输优先级所分配的专用频谱资源可以进一步划分为:为紧急业务分配的频谱资源,和为非紧急业务分配的频谱资源; [0112] Specifically, as the D2D data packet transmission priority corresponding to the spectrum allocated dedicated resources may be further divided into: spectral spectrum resources emergency service resource allocation, and non-urgent traffic distribution;

[0113]本发明实施例可判断所述D2D数据包的业务紧急等级;若所述D2D数据包的业务紧急等级为紧急业务,则确定为所述D2D数据包对应的传输优先级所分配的专用频谱资源中的为紧急业务分配的频谱资源,在所确定的为紧急业务分配的频谱资源中,确定各数据包副本的传输频率;若所述D2D数据包的业务紧急等级为非紧急业务,则确定为所述D2D数据包对应的传输优先级所分配的专用频谱资源中的为非紧急业务分配的频谱资源,在所确定的为非紧急业务分配的频谱资源中,确定各数据包副本的传输频率; [0113] embodiments of the invention may be determined urgency level of the D2D traffic packet; if the urgency level D2D traffic packet is an emergency service, is determined as the transmission priority assigned dedicated packet corresponds D2D spectrum resources, spectrum resources allocated for the emergency service in the determined spectrum resources allocated for the emergency service, determines the transmission frequency of each copy of the packet; if the urgency level of the D2D traffic packet non-emergency service, the is determined as a non-emergency service resources allocated spectrum spectrum resources dedicated transmission priority assigned to the data packet corresponding to the D2D in a non-emergency service spectrum resources allocated to the determined, determining the transmission of a copy of each packet frequency;

[0114]具体的,在V2X场景下,图11示出了频谱资源分配的另一示意图,在为V2X业务所分配的频谱资源中,还进一步划分了为V2X紧急业务所分配的频谱资源,和为V2X非紧急业务所分配的频谱资源,V2X紧急业务为追尾、紧急制动等需要快速处理的业务,紧急业务和非紧急业务可根据实际情况预先设定; [0114] Specifically, in the scenario V2X, FIG. 11 shows a schematic diagram of another spectrum allocation of the spectrum resources for the assigned traffic V2X, further divided into spectrum resources allocated V2X emergency service, and V2X spectrum resources allocated non-emergency service, for the rear-end V2X emergency operations, emergency braking, and other services requiring fast processing, emergency services and non-emergency service may be preset according to actual situation;

[0115]可以看出,在为V2X业务分配的专用频谱资源可以包括:为V2X紧急业务分配的频谱资源,和为V2X非紧急业务分配的频谱资源;具体的,在为V2X业务分配的专用频谱资源中,确定各数据包副本的传输频率时,本发明实施例可在确定所需传输的D2D数据包属于V2X业务后,判断D2D数据包的业务紧急等级,从而根据不同的业务紧急等级,在相应的频谱资源上确定各数据包副本的不同传输频率; [0115] As can be seen, the spectrum for the dedicated resource allocation service may include V2X: V2X emergency service spectrum resource allocation, and V2X spectrum resources allocated for non-emergency services; Specifically, in the dedicated spectrum allocated for service V2X when the resource, the copy of each packet to determine the transmission frequency, embodiments of the present invention may be determined after D2D data packet belongs V2X required transmission service, whether the service level emergency D2D data packet to the emergency service according to different levels, in determining different transmission frequency of each copy of the packet on the corresponding spectrum resource;

[0117]步骤S700、判断所述D2D数据包的业务紧急等级; [0117] step S700, the urgency level determines the D2D traffic packet;

[0118] D2D数据包可以为V2X数据包。 [0118] D2D V2X data packets may be packets.

[0119]步骤S710、若所述D2D数据包的业务紧急等级为紧急业务,则从所述专用频谱资源中为紧急业务分配的频谱资源中,确定各数据包副本的传输频率; [0119] step S710, the level of the emergency if the service D2D data packet is an emergency service, dedicated spectrum from the spectrum resource for resource allocation in an emergency service, determines the transmission frequency of each copy of the data packet;

[0120]步骤S720、若所述D2D数据包的业务紧急等级为非紧急业务,则从所述专用频谱资源中为非紧急业务分配的频谱资源中,确定各数据包副本的传输频率。 [0120] step S720, the emergency service if the level of non-urgent packets D2D traffic, from the spectrum resources dedicated non-emergency service spectrum resource allocation, determines the transmission frequency of each copy of the data packet.

[0121]本发明实施例中V2X业务由于使用了专用的频谱资源,因此,对于可靠性和时延要求很高的业务可以避免由于抢占不了资源带来的时延,也可以避免资源复用产生的干扰;而且由于采用了跳频的方式实现的多份数据发送,也一定程度上,降低了使用“唯一”资源时,资源复用带来的干扰对信号可靠性的影响; [0121] Examples V2X dedicated traffic due to the use of spectrum resources, therefore, for a very high reliability and delay requirement of the service can not be avoided due to the delay caused to seize the resources, the resources can be avoided to produce a multiplexed embodiment of the present invention interference; and thanks to the multiple frequency hopping manner of data transmission, but also to a certain extent, reduce the use of "unique" resource, resource reuse affect the interference caused by a signal reliability;

[0122]可选的,在本发明实施例中,跳频的map(范围)可以是在基站RRC所指示的可用传输频率范围内,或广播通信所指示的资源池中随机选择,或也可以根据通信质量进行配置;如基站通过信道测量信息,可以获得V2X信道的通信质量,基站将该通信质量通知发送端,则发送端可根据此通信质量,选择通信较优的频率跳频map; [0122] Alternatively, in the embodiment, the frequency hopping map (range) may be in the available transmission frequency of the base station indicated by the RRC, random selection or a broadcast communication resource pool indicated embodiment of the present invention, or may be configured according to the communication quality; base station channel measurement information, the communication quality may be obtained V2X channel, the communication quality of the base station notifies the transmitting end, the transmitting end according to the communication quality, selecting a communication Map superior frequency hopping;

[0123]具体的,发送端可确定当前信道的通信质量;根据所述通信质量确定通信质量符合设定条件的频率范围,在所述频率范围中以跳频方式确定各数据包副本的传输频率。 [0123] Specifically, the transmission side may determine the communication quality of the current channel; determines that the communication quality meets the setting condition according to the frequency range of the communication quality, the frequency hopping to determine the transmission frequency of each copy of the packet in the frequency range .

[0124]可选的,由于D2D数据包重传机制的变化,也会改变到调度信令的结构;因此,本发明实施例可以利用目前3GPP协议中的SA定义的bit map保留字节,实现根据当前信道的通信质量所进行的资源调度。 [0124] Alternatively, since variation D2D packet retransmission mechanism, the structure will change scheduling signaling; Accordingly, embodiments of the present invention may be utilized to retain the current byte bit map defined by 3GPP SA protocol, implemented resource scheduling performed in accordance with current communication quality of the channel.

[0125]本发明实施例提供的D2D数据包传输方法可实现较小的数据传输时延,达到较好的时延控制目的,同时,由于是在频域上进行了调频处理,使得各数据包副本的传输频率不同,因此在传输D2D数据包时,也可获得一定的频率选择性增益。 [0125] D2D data packet transmission method according to embodiments of the present invention can realize a smaller data transmission delay, delay achieve better control purposes, at the same time, since the frequency modulation process is performed in the frequency domain, so that each data packet copies of different transmission frequency, and therefore when transmitting D2D data packets, can be obtained a certain frequency selective gain.
