Description

一種資源調度和碰撞指示的方法及設備 Method and equipment for resource scheduling and collision indication

本發明屬於無線通訊技術領域，特別是關於一種資源調度和碰撞指示的方法及設備。 The present invention belongs to the field of wireless communication technology, and particularly relates to a method and device for resource scheduling and collision indication.

目前無線通訊領域主要有兩種通信方式：經由網路的通信方式和直接通信方式。 At present, there are mainly two communication methods in the field of wireless communication: a communication method via a network and a direct communication method.

1、經由網路的通信方式 1.Communication via the network

傳統的經由網路通信的方式如圖1A所示，其中基地台和終端(UE)之間使用Uu介面：對於經由網路的通信方式，發送終端(UE)如果要發送資料，那麼資料首先通過終端和其服務基地台之間的Uu介面發送給基地台，然後基地台將接收端到的資料經由核心網路設備送到外部伺服器，由外部伺服器判斷資料是否需要發送給其他終端，如果需要，則將資料轉發給接收終端的服務基地台，接收終端的服務基地台再將資料通過Uu介面發送給接收終端。 The traditional way of communicating via the network is shown in Figure 1A, in which the Uu interface is used between the base station and the terminal (UE): For the way of communicating via the network, if the sending terminal (UE) wants to send data, the data first passes The Uu interface between the terminal and its serving base station is sent to the base station, and then the base station sends the received data to the external server through the core network device, and the external server determines whether the data needs to be sent to other terminals. If necessary, the data is forwarded to the service base station of the receiving terminal, and the service base station of the receiving terminal sends the data to the receiving terminal through the Uu interface.

2、直接通信方式 2.Direct communication method

直接通信的方式如圖1B所示：終端之間採用D2D(Device to Device，設備到設備)技術實現直接通信。 The direct communication method is shown in FIG. 1B: D2D (Device to Device, device to device) technology is used to implement direct communication between terminals.

V2X(Vehicle-to-Everything，車與萬物)通信是目前通信領域一個熱門議題。V2X通信主要包含三方面內容：V2V(Vehicle-to-Vehicle，車到車)：車上的OBU(On Broad Unit，車載單元)之間的通信。 V2X (Vehicle-to-Everything) communication is the current communication leader Domain is a hot topic. V2X communication mainly includes three aspects: V2V (Vehicle-to-Vehicle, car-to-vehicle): communication between OBU (On Broad Unit, on-board unit) on the car.

V2I(Vehicle-to-Infrastructure，車道網路)：車和RSU(Road Side Unit，路側設備)之間的通信。 V2I (Vehicle-to-Infrastructure, lane network): Communication between a car and a Road Side Unit (RSU).

V2P(Vehicle-to-Pedestrian，車到行人)：車和行人之間的通信。 V2P (Vehicle-to-Pedestrian): Communication between a vehicle and a pedestrian.

在D2D中，SA(Scheduling assignment，調度分配資訊)與所指示的資料在同一個調度週期內，且SA資源池在資料資源池之前。SA用於指示D2D終端所發資料的時頻資源、調製編碼等級等解調相關的資訊。 In D2D, the scheduling assignment information (SA) is in the same scheduling period as the indicated data, and the SA resource pool precedes the data resource pool. SA is used to indicate demodulation-related information such as time-frequency resources and modulation and coding levels of data sent by the D2D terminal.

SA與Data(資料)資源池間的關係，如圖1C所示。 The relationship between SA and Data resource pool is shown in Figure 1C.

目前的SA與Data資源池間的關係，當調度週期較大時，資料的發送延遲也比較大。 The current relationship between the SA and the Data resource pool, when the scheduling period is large, the data transmission delay is also relatively large.

例如：調度週期是40ms，SA資源池是(0~7)+k*40；其中K是整數。 For example: the scheduling period is 40ms, and the SA resource pool is (0 ~ 7) + k * 40; where K is an integer.

當有高層資料在子訊框8到達時，相應的SA最快只能在子訊框(0~7)+40中發送，資料則最快只能在(8~39)+40子訊框發送，對於延遲要求高的業務則無法支持。 When high-level data arrives in sub-frame 8, the corresponding SA can only be sent in sub-frame (0 ~ 7) +40, and the fastest data can only be in (8-39) +40 sub-frame. Send, but cannot support services with high delay requirements.

目前D2D傳輸中無法對發生的碰撞進行指示。 At present D2D transmission cannot indicate the collision that occurred.

本發明提供一種資源調度的方法及設備，用以解決現有技術中存在的如果調度週期較大，資料發送延遲比較長，無法滿足延遲要求高的業務問題。 The invention provides a method and a device for resource scheduling, which are used to solve the existing problems in the prior art: if the scheduling period is large, the data transmission delay is relatively long, and the delay requirement cannot be met.

為了使本發明的目的、技術方案和優點更加清楚，下面將結合附圖對本發明作進一步地詳細描述，顯然，所描述的實施例僅僅是本發明一部份實施例，而不是全部的實施例。基於本發明中的實施例，本領域普通技術人員在沒有做出創造性勞動前提下所獲得的所有其它實施例，都屬於本發明保護的範圍。 In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all the embodiments. . Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

在下面的介紹用以V2X終端為例進行說明，在實施中，V2X終端包括但不限於下列終端中的一種：V2V終端、V2I終端和V2P終端。 The following description uses V2X terminals as an example for description. In implementation, V2X terminals include but are not limited to one of the following terminals: V2V terminals, V2I terminals, and V2P terminals.

本發明實施例提供的資源調度的方法中由於SA(Scheduling assignment，調度分配資訊)資源池和資料資源池在時域上連續，且在頻域上進行劃分，所以在有SA需要發送時，直接從SA資源池中選取SA可用資源，並在該SA可用資源之後選取對應的資料可用資源發送資料，從而減小了資料發送的延遲，可以更好地滿足延遲要求高的業務。 In the method for resource scheduling provided by the embodiment of the present invention, due to SA (Scheduling assignment, scheduling and allocation information) The resource pool and the data resource pool are continuous in the time domain and divided in the frequency domain, so when there is an SA to send, the SA available resources are directly selected from the SA resource pool and available in the SA. After the resources are selected, corresponding resources are available to send the materials, thereby reducing the delay in sending the materials, and can better satisfy the services with high delay requirements.

其中，本發明實施例SA對應的資料為在SA所指示的時頻資源上所發送的資料。 The data corresponding to the SA in the embodiment of the present invention is data sent on the time-frequency resource indicated by the SA.

本發明實施例SA資源池和資料資源池的佈置方式可以參見圖2A。 For the arrangement manner of the SA resource pool and the data resource pool in the embodiment of the present invention, refer to FIG. 2A.

圖2A中，位於SA資源池中的資源1為承載SA1的資源，SA1的資源對應的資料的承載資源是資料資源池中的資源1；位於SA資源池中的資源2為承載SA2的資源，SA2的資源對應的資料的承載資源是資料資源池中的資源2。 In FIG. 2A, the resource 1 located in the SA resource pool is a resource carrying SA1, and the data carrying resource corresponding to the resource of SA1 is resource 1 in the data resource pool; the resource 2 located in the SA resource pool is a resource carrying SA2, The bearer resource of the data corresponding to the resource of SA2 is resource 2 in the data resource pool.

從圖2A可以看出：SA資源池和資料資源池在時域上連續，且在頻域上進行劃分；也就是說，本發明實施例在同一時間可以將SA和資料同時在不同頻率上發送，不需要設置調度週期，這樣在有SA需要發送時可以隨時發送SA，並在SA之後的任何時刻選擇對應的資料的發送時間，從而不會出現在SA週期末端有資料需要發送，由於無法發送SA，必須等到下一個SA週期發送SA，致使增加了資料的延遲的情況發生，縮短了資料發送延遲。 It can be seen from FIG. 2A that the SA resource pool and the data resource pool are continuous in the time domain and are divided in the frequency domain; that is, the embodiment of the present invention can send SA and data at different frequencies at the same time. It is not necessary to set a scheduling period, so that when an SA needs to be sent, the SA can be sent at any time, and the corresponding data sending time can be selected at any time after the SA, so that there will be no data to be sent at the end of the SA period. The SA must wait until the next SA cycle to send the SA, which increases the delay of the data and shortens the delay of the data transmission.

如圖2B所示，本發明實施例資源調度的系統包括：V2X發送終端10，用於從SA資源池中確定SA可用資源，以及從資料資源池中確定資料可用資源，其中SA資源池和資料資源池在時域上連續，且在頻域上進行劃分，SA對應的資料可用資源位於該SA可用資源之後；通過SA可用資源發送SA，以及通過資料可用資源發送資料。 As shown in FIG. 2B, the resource scheduling system according to the embodiment of the present invention includes: a V2X sending terminal 10, configured to determine SA available resources from the SA resource pool, and determine data available resources from the data resource pool, where the SA resource pool and data The resource pool is continuous in the time domain, and Divided in the frequency domain, the data available resources corresponding to the SA are located behind the SA available resources; the SA is sent through the SA available resources, and the data is sent through the data available resources.

V2X接收終端20，用於通過SA資源池中的SA可用資源接收SA；通過SA確定對應資料所使用的時頻資源，並在該時頻資源上接收資料。 The V2X receiving terminal 20 is configured to receive the SA through the SA available resources in the SA resource pool; determine the time-frequency resource used by the corresponding data through the SA, and receive the data on the time-frequency resource.

在實施中，當V2X發送終端在子訊框i時有資料包需要發送，則開始從SA資源池中確定SA可用資源，以及從資料資源池中確定資料可用資源。 In implementation, when there is a data packet to be sent when the V2X sending terminal is in the sub-frame i, it starts to determine the SA available resources from the SA resource pool and determines the data available resources from the data resource pool.

假設約定資料是在Ld個子訊框內傳輸完成，資料的傳輸延遲是D。 Assume that the agreed data is transmitted in Ld sub-frames, and the transmission delay of the data is D.

V2X發送終端可以在D-Ld-2(這裡的2也可以是其他數字)內隨機選擇一個整數，該整數為D1。 The V2X transmitting terminal may randomly select an integer within D-Ld-2 (here, 2 may be another number), and the integer is D1.

V2X發送終端在子訊框i+2+D1~i+1+D1+Ld內選擇出用於傳輸資料的時頻單元(該時頻單元位於資料資源池中)。 The V2X transmitting terminal selects a time-frequency unit (the time-frequency unit is located in the data resource pool) for transmitting data in the sub-frames i + 2 + D1 ~ i + 1 + D1 + Ld.

假設資料首次傳輸是在i+2+D1+D2進行，則需要從子訊框i~i+1+D1+D2隨機選擇用於傳輸SA的時頻單元(該時頻單元位於SA資源池中)。 Assume that the first transmission of data is performed at i + 2 + D1 + D2, then the time-frequency unit for transmitting SA needs to be randomly selected from the sub-frames i ~ i + 1 + D1 + D2 (the time-frequency unit is located in the SA resource pool) ).

其中，D2為資料首次傳輸與資料時間窗的起始點之間的時間間隔。 Among them, D2 is the time interval between the first transmission of data and the starting point of the data time window.

可選的，可以讓用於傳輸SA的子訊框與用於傳輸資料的子訊框在一定概率上是同一子訊框，比如設置該概率為50%，這樣可以降低SA與Data間的干擾。 Optionally, the sub-frame used for transmitting SA and the sub-frame used for transmitting data can be the same sub-frame with a certain probability. For example, setting the probability to 50% can reduce the interference between SA and Data. .

這裡需要說明的是，用於傳輸SA的子訊框與用於傳輸資料的子訊框是同一子訊框，則與SA同一個子訊框發送的資料為與該SA不同的SA對應的資料。 What needs to be explained here is that the sub-frame used for transmitting SA and the data used for transmitting The sub-frame of is the same sub-frame, so the data sent by the same sub-frame as the SA is data corresponding to an SA that is different from the SA.

比如用於傳輸SA1的子訊框A也是傳輸資料2的子訊框，則這種情況是用於傳輸SA的子訊框與用於傳輸資料的子訊框是同一子訊框。但是SA1對應的資料不是資料2，用於傳輸SA1對應的資料的子訊框位於子訊框A之後，用於傳輸資料2對應的SA的子訊框位於子訊框A之前。 For example, the sub-frame A for transmitting SA1 is also the sub-frame for transmitting data 2. In this case, the sub-frame for transmitting SA and the sub-frame for transmitting data are the same sub-frame. However, the data corresponding to SA1 is not data 2. The sub-frame for transmitting the data corresponding to SA1 is located after sub-frame A, and the sub-frame for transmitting the SA corresponding to data 2 is located before sub-frame A.

可選的，本發明實施例的PRB(Physical Resource Block，物理資源塊)分配粒度為Y個PRB，Y為正整數。如果該承載SA的子訊框與承載資料的子訊框為同一個子訊框，Y可以是大於1的整數。增大PRB分配粒度可以降低資料盲檢的複雜度，同時減少資源指示所需開銷。 Optionally, the PRB (Physical Resource Block) allocation granularity in the embodiment of the present invention is Y PRBs, and Y is a positive integer. If the sub-frame carrying the SA and the sub-frame carrying the data are the same sub-frame, Y may be an integer greater than 1. Increasing the granularity of PRB allocation can reduce the complexity of blind data inspection and reduce the overhead required for resource indication.

在實施過程中，為了保證SA傳輸成功率，一般會選擇多次發送同一個SA。具體發送的次數可以根據需要進行設定。 In the implementation process, in order to ensure the success rate of SA transmission, generally the same SA is selected to be sent multiple times. The number of specific sending times can be set as needed.

基於此，該V2X發送終端需要針對每次發送的SA，從SA資源池中確定SA可用資源，具體的確定方式有很多種，下面列舉幾種。 Based on this, the V2X sending terminal needs to determine the available resources of the SA from the SA resource pool for each SA that is sent, and there are many specific determination methods, which are listed below.

方式一、該V2X發送終端從SA資源池中確定用於首次傳輸的子訊框，以及用於重傳的子訊框。 Method 1: The V2X sending terminal determines a sub-frame for the first transmission and a sub-frame for retransmission from the SA resource pool.

這種方式下將SA資源池中的子訊框分成兩類，一類是用於首次傳輸SA的子訊框，另一類是用於重傳SA的子訊框。 In this way, the sub-frames in the SA resource pool are divided into two types, one is a sub-frame used for the first transmission of SA, and the other is a sub-frame used for retransmission of SA.

該V2X發送終端從SA資源池中確定用於首次傳輸SA的子訊框，以及用於重傳SA的子訊框；相應的，該V2X發送終端通過確定的用於首次傳輸的子訊框發送SA，以及通過用於重傳的子訊框發送SA。 The V2X sending terminal determines from the SA resource pool the sub-frame used for the first transmission of SA and the sub-frame used for retransmission of the SA; correspondingly, the V2X sending terminal sends the determined sub-frame for the first transmission. SA, and SA is sent through a sub-frame for retransmission.

這裡的用於首次傳輸SA的子訊框是多個子訊框，用於重傳的子訊框是多個子訊框。該V2X發送終端從用於首次傳輸SA的多個子訊框中選擇一個子訊框發送SA；以及從用於重傳SA的多個子訊框中選擇一個子訊框發送SA。 Here, the sub-frame used for the first transmission of SA is multiple sub-frames, and the sub-frame used for retransmission is multiple sub-frames. The V2X transmitting terminal selects one sub-frame to transmit SA from multiple sub-frames for transmitting SA for the first time; and selects one sub-frame to transmit SA from multiple sub-frames for retransmitting SA.

可選的，用於首次傳輸SA的子訊框為奇子訊框，即子訊框編號為奇數的子訊框；用於重傳的子訊框為偶子訊框，即子訊框編號為偶數的子訊框。 Optionally, the sub-frame used for the first transmission of SA is an odd sub-frame, that is, the sub-frame number is an odd sub-frame; the sub-frame used for retransmission is an even sub-frame, that is, the sub-frame number. Is an even number of child frames.

假設該V2X發送終端通過偶子訊框L(i)的第m(i)個PRB發送SA，則通過奇子訊框L(i+1)的第m(i+1)個PRB發送SA；若首次傳輸和重傳的最大時間間隔為L-1個子訊框，每個子訊框可用的PRB數為M，則：m(i+1)=(m(i)+M/x)mod(M)；L(i+1)=L(i)+(m(i)*x)mod(L)+1；其中，x為傳輸SA的次數，M和L為偶數，m(i)的取值範圍為0~M-1，i的取值範圍是0~x-1。 Assume that the V2X transmitting terminal sends SA through the m (i) th PRB of the even sub-frame L (i), and then sends SA through the m (i + 1) -th PRB of the odd sub-frame L (i + 1); If the maximum time interval between first transmission and retransmission is L-1 sub-frames, and the number of PRBs available for each sub-frame is M, then: m (i + 1) = (m (i) + M / x) mod ( M); L (i + 1) = L (i) + (m (i) * x) mod (L) +1; where x is the number of SA transmissions, M and L are even numbers, and m (i) The value ranges from 0 to M-1, and i ranges from 0 to x-1.

在上面的公式中，x=2時，對應的是SA兩次傳輸，首傳在偶子訊框，重傳在子訊框進行。當x>2時，假設n為子訊框編號，則第m次傳輸在mod(n，x)=m的子訊框傳輸。其中mod(n，x)是對x取模。 In the above formula, when x = 2, it corresponds to two transmissions of SA, the first transmission is in the even sub frame, and the retransmission is performed in the sub frame. When x> 2, assuming that n is the number of the sub-frame, the m-th transmission is transmitted in the sub-frame with mod (n, x) = m. Where mod (n, x) is modulo x.

需要說明的是，這裡的m(i)和m(i+1)是邏輯上的子載波編號。在實際的物理分配上，如圖2A所示，SA資源池是在整個V2X可用載波的兩端來劃分的。假設V2X載波頻寬是Nc個子載波，其中子載波0~M/2-1和N-M/2~Nc-1用於傳輸SA。則這些子載波的邏輯編號為0~M-1。 It should be noted that m (i) and m (i + 1) here are logical subcarrier numbers. In actual physical allocation, as shown in FIG. 2A, the SA resource pool is divided at both ends of the entire V2X available carrier. It is assumed that the V2X carrier bandwidth is Nc subcarriers, where subcarriers 0 ~ M / 2-1 and N-M / 2 ~ Nc-1 are used to transmit SA. The logical numbers of these subcarriers are 0 ~ M-1.

可選的，如果V2X發送終端接收到多個相同的SA，可以將接收到的同一個SA進行軟合併，這樣可以獲得合併增益。 Optionally, if the V2X sending terminal receives multiple identical SAs, the same SA received may be soft-merged, so that a combining gain can be obtained.

下面列舉一個例子： Here is an example:

1、資源的初選或重選 1.Primary or reselection of resources

在選資源前，V2X發送終端根據接收的SA，標識出資源的使用情況；具體的，如果V2X發送終端接收到SA指示出子訊框x的時頻單元y被另一個V2X所使用，且佔用週期是z。那麼子訊框x+s*z的時頻單元y均標識為佔用。直到連續X(X為預先設置的一個值)次，沒有SA指示相應的時頻單元被佔用，那麼該時頻單元被置為空閒。 Before selecting a resource, the V2X sending terminal identifies the usage of the resource according to the received SA; specifically, if the V2X sending terminal receives the SA indicating that the time-frequency unit y of the sub-frame x is used by another V2X and occupied The period is z. Then, the time-frequency units y of the subframe x + s * z are all marked as occupied. Until X (X is a preset value) consecutive times, no SA indicates that the corresponding time-frequency unit is occupied, then the time-frequency unit is set to idle.

假定資料總的傳輸次數是2，且初傳和重傳限定在一個Ld ms的時間窗內。 It is assumed that the total number of data transmissions is two, and the initial transmission and retransmission are limited to a time window of Ld ms.

V2X發送終端在D-Ld-2內隨機選擇一個整數，該整數是D1，在子訊框i+2+D1~i+1+D1+Ld內選擇出用於傳輸資料的時頻單元。 The V2X transmitting terminal randomly selects an integer in D-Ld-2, the integer is D1, and selects a time-frequency unit for transmitting data in the sub-frames i + 2 + D1 ~ i + 1 + D1 + Ld.

比如最優選空閒的子訊框；其次優選子訊框功率最大的子訊框。 For example, the idle sub-frame is most preferred; the sub-frame with the highest power of the sub-frame is the next most preferred.

方式二、除了上述選擇方式一，該V2X發送終端還可以從SA資源池中隨機選擇至少兩個子訊框；並通過選擇的每個子訊框分別發送SA。 Method 2: In addition to the above-mentioned selection method 1, the V2X sending terminal may also randomly select at least two sub-frames from the SA resource pool; and send SA through each selected sub-frame separately.

可選的，該V2X發送終端可以從Ld個子訊框中隨機選擇滿足重複度低於門限的多個時頻單元作為選定的發送資料資源。如果沒有滿足要求的時頻單元，再重新選擇資料發送窗。資料發送窗最多重選S次。這裡的重複度是選取的時頻單元中被同時被其他V2X終端佔用的比例，比如選取10個時頻單元，其中3個被其他V2X終端佔用，則選取的時頻單元的重複度為0.3。 Optionally, the V2X transmitting terminal may randomly select multiple time-frequency units satisfying the repetition degree lower than the threshold from the Ld sub-frames as the selected sending data resource. If there is no time-frequency unit that meets the requirements, re-select the data sending window. The data sending window can be reselected at most S times. The degree of repetition here is the proportion of the selected time-frequency unit that is occupied by other V2X terminals at the same time. For example, if 10 time-frequency units are selected and 3 of them are occupied by other V2X terminals, the weight of the selected time-frequency unit is Repetition was 0.3.

假定選定的資料首次傳輸是在i+2+D1+D2進行，則SA所需時頻資源需要從子訊框i~i+1+D1+D2隨機選擇。也可以一定概率SA選擇與資料相同的子訊框進行發送，例如50%的概率。 Assuming that the selected data is transmitted for the first time at i + 2 + D1 + D2, the time-frequency resources required by the SA need to be randomly selected from the sub-frames i ~ i + 1 + D1 + D2. It is also possible to select a certain probability SA to send the same sub-frame as the data, for example, a 50% probability.

在實施中，本發明實施例的該SA包括但不限於下列資訊中的部分或全部：用於表示SA首次傳輸或重傳與對應資料首次傳輸的時間間隔的延遲指示資訊；用於表示SA指示的資源的資源指示資訊；用於表示資料傳輸在時間窗內所佔用的子訊框資源的發送模式資訊；資料調製與編碼資訊；用於表示下次資料的生效間隔的時長指示資訊；用於表示終端的發送時鐘相對接收時鐘的的定時提前量；用於表示該V2X發送終端之前作為V2X接收終端接收時檢測到的碰撞資訊；V2X發送終端的終端標識。 In implementation, the SA in the embodiment of the present invention includes but is not limited to part or all of the following information: delay indication information used to indicate the time interval between the first transmission or retransmission of the SA and the first transmission of the corresponding data; and used to indicate the SA indication Resource indication information of the resource; used to indicate the transmission mode information of the sub-frame resource occupied by the data transmission within the time window; data modulation and coding information; used to indicate the length of the next effective interval of the data; Is used to indicate the timing advance of the sending clock of the terminal relative to the receiving clock; used to indicate the collision information detected when the V2X sending terminal was previously received as a V2X receiving terminal; the terminal identification of the V2X sending terminal.

可選的，延遲指示資訊：佔用7位元。 Optional, delay indication information: Occupies 7 bits.

資源指示資訊：，10MHz頻寬下需要的位元數是11位元；表示V2X系統可以使用的PRB個數。 Resource instruction information: , The number of bits required for a 10MHz bandwidth is 11 bits; Indicates the number of PRBs that can be used in a V2X system.

發送模式資訊，佔用7位元(在實施中，可以縮減，例如8個子訊框，固定兩次傳輸，需要的位元數是3位元；或者也可以指示128子訊框內，固定兩次傳輸)是指在一個時間視窗內，每次傳輸所佔用的子訊框。子訊框的編號是以時間窗起始點為0的相對編號。發送模式資訊實際上指示出資料傳輸在時間窗內所佔用的子訊框資源。這個時間窗是以SA重傳子訊框+延遲指示為起始點。 Send mode information, occupying 7 bits (in implementation, it can be reduced, for example, 8 sub-frames, fixed for two transmissions, the number of bits required is 3 bits; or 128 sub-frames can also be indicated In the frame, two transmissions are fixed) refers to the sub-frame occupied by each transmission in a time window. The number of the sub-frame is a relative number with the starting point of the time window as 0. The sending mode information actually indicates the sub-frame resources occupied by the data transmission within the time window. This time window starts with the SA retransmission sub-frame + delay indication.

調製與編碼方案：佔用5位元。 Modulation and coding scheme: Occupies 5 bits.

下次生效間隔：佔用2位元，可以使接收側提前知道下次資料的發送時間，從而可以提前進行準備(比如可以設置無窮大(或無效值)，100ms，500ms，1000ms。如果是無窮大(或無效值)，則接收側就知道下次資料接收完成後，整個資料就接收完成了，後續沒有持續的資料需要發送)。 Next effective interval: Occupies 2 bits, so that the receiving side knows in advance the next data sending time, so that it can prepare in advance (for example, you can set infinity (or invalid value), 100ms, 500ms, 1000ms. If it is infinite (or Invalid value), then the receiving side knows that after the next data reception is completed, the entire data is received, and there is no continuous data to be sent in the future).

定時提前量：佔用11位元。 Timing advance: Occupies 11 bits.

碰撞信息：可以是任何能夠表示該V2X發送終端之前作為V2X接收終端接收時發生碰撞的資訊，比如可以是碰撞資訊為SA指示的資源上發生碰撞的終端的個數或SA指示的資源上發生碰撞的終端的終端標識；如果是SA指示的資源上發生碰撞的終端的個數，一般情況最多會發生3個碰撞，所以可以佔用2位元，指示資料中傳輸0、1、2或3個碰撞指示資訊；如果是發生碰撞的終端的終端標識，一般情況最多會發生3個碰撞，所以可以佔用24位元用於指示3個碰撞指示，每一個碰撞指示為8位元的終端標識，終端標識如果是00000000，則表示該指示為空。 Collision information: It can be any information that can indicate that the V2X sending terminal received a collision as a V2X receiving terminal before. For example, it can be the number of terminals that collided on the resource indicated by the SA information or a collision on the resource indicated by the SA. Terminal identification of the terminal; if it is the number of terminals that have collided on the resource indicated by SA, in general, a maximum of 3 collisions will occur, so it can occupy 2 bits, indicating that 0, 1, 2, or 3 collisions are transmitted in the data. Instruction information; if it is the terminal identification of the terminal where the collision occurred, a maximum of 3 collisions may occur, so it can occupy 24 bits to indicate 3 collision instructions, each collision instruction is an 8-bit terminal identification, terminal identification If it is 00000000, the indication is empty.

V2X發送終端的終端標識，比如UEID(終端標識)：佔用8位元。 The terminal identification of the V2X sending terminal, such as UEID (terminal identification): Occupies 8 bits.

在實施中，如果只需要通知碰撞資訊，則本發明實施例的SA可以只包含碰撞資訊，這樣的設計可以降低傳輸開銷。 In implementation, if only the collision information needs to be notified, the SA of the embodiment of the present invention may only include the collision information, and such a design can reduce transmission overhead.

如果碰撞資訊包括多個(0~3)發生衝突終端的終端構成，則最多只需要24位元，不需要攜帶發生碰撞的延遲指示、資源指示和發送模式；如果碰撞資訊包括發生碰撞的終端的個數，則可以將碰撞個數指示在SA上發送，具體發生碰撞的ID則與資料在同一個通道中發送，碰撞ID的調製方式和編碼率是固定的。 If the collision information includes the terminal configuration of multiple (0 ~ 3) conflicting terminals, it only needs a maximum of 24 bits, and it is not necessary to carry the collision delay indication, resource indication and transmission mode; if the collision information includes the collision terminal's The number of collisions can be indicated on the SA, and the specific collision ID is sent in the same channel as the data. The modulation method and coding rate of the collision ID are fixed.

在傳輸時，可以先傳包含碰撞資訊的SA，再傳資料。所以在SA中只要預留2個位元可以指示相應的資源中有幾個終端的衝突指示資訊即可。 During transmission, the SA containing the collision information can be transmitted first, followed by the data. Therefore, as long as two bits are reserved in the SA, the conflict indication information of several terminals in the corresponding resource can be indicated.

為了降低SA資料對業務資料的干擾，在發送SA資訊時，可降低SA的發射功率。 In order to reduce the interference of the SA data on the service data, when transmitting the SA information, the transmission power of the SA can be reduced.

可選的，SA在傳輸時，可以採用1個PRB承載，QPSK(Quadrature Phase Shift Keying，四相相移鍵控)調製，有效編碼率為：0.28(38bits)或是0.34(49bits)。 Optionally, during transmission, the SA may use 1 PRB bearer, QPSK (Quadrature Phase Shift Keying) modulation, and an effective coding rate: 0.28 (38 bits) or 0.34 (49 bits).

可選的，若該承載SA的子訊框與承載資料的子訊框為同一個子訊框，則該資料調製與編碼資訊為與SA在同一個子訊框的資料調製與編碼資訊。 Optionally, if the sub-frame carrying the SA and the sub-frame carrying the data are the same sub-frame, the data modulation and coding information is data modulation and coding information in the same sub-frame as the SA.

比如用於傳輸SA1的子訊框A也是傳輸資料2的子訊框，SA1對應的資料為資料1，則SA1中的資料調製與編碼資訊為資料2的資料調製與編碼資訊，不是資料1的資料調製與編碼資訊。 For example, the sub-frame A used to transmit SA1 is also the sub-frame of data 2. The data corresponding to SA1 is data 1. The data modulation and coding information in SA1 is the data modulation and coding information of data 2, not the data 1. Data modulation and coding information.

這樣的好處是：若該V2X接收終端未接收到與該SA位於同一個子訊框中的資料對應的SA，則可以根據接收到的該SA中資料調製與編碼資訊，以及PRB分配粒度，對承載該SA的子訊框進行盲檢。 This advantage is that if the V2X receiving terminal does not receive an SA corresponding to the data in the same sub-frame as the SA, it can modulate and encode information based on the received data in the SA and the PRB allocation granularity. The sub-frame carrying the SA is blindly checked.

還以上面的例子進行闡述：V2X接收終端未接收資料2對應的SA，則V2X接收終端可以根據SA1中的資料調製與編碼資訊，以及PRB分配粒度，對承載該SA1的子訊框進行盲檢，從而能夠得到資料2。 The above example is also used to illustrate: if the V2X receiving terminal does not receive the SA corresponding to the data 2, the V2X receiving terminal can perform blind detection on the sub-frame carrying the SA1 according to the data modulation and coding information in SA1 and the PRB allocation granularity. , So that you can get information 2.

可選的，若該承載SA的子訊框與承載資料的子訊框不是同一個子訊框，則該資料調製與編碼資訊為該SA對應的資料的資料調製與編碼資訊。 Optionally, if the sub-frame carrying the SA and the sub-frame carrying the data are not the same sub-frame, the data modulation and coding information is data modulation and coding information of the data corresponding to the SA.

比如用於傳輸SA1的子訊框A上沒有資料，SA1對應的資料為資料1，則SA1中的資料調製與編碼資訊為資料1的資料調製與編碼資訊。 For example, there is no data on the sub-frame A used to transmit SA1, and the data corresponding to SA1 is data 1, then the data modulation and coding information in SA1 is the data modulation and coding information of data 1.

在實施中，當V2X接收終端發現衝突後，發碰撞的ID資訊會與資料隨路發送。即發碰撞的ID資訊獨立編碼，但是與資料複用在同一個物理通道上發送。 In implementation, when the V2X receiving terminal finds a conflict, the ID information of the collision will be sent along with the data. That is, the ID information of the collision is independently encoded, but is transmitted on the same physical channel as the data multiplex.

本發明實施例可以設定SA的功率門限值Ps，只有SA被正確解碼，且SA的接收功率超過功率門限值Ps，才認為該SA為衝突判斷SA。比如在V2X通信過程中，V2X發送終端會廣播其位置資訊，所以V2X接收終端可以統計目標通信範圍內SA的最小接收功率；或者可以設定SA的距離門限值，只有SA被正確解碼，且發送SA的V2X終端和接收SA的V2X終端之間的距離小於距離門限值，認為該SA為衝突判斷SA。比如在V2X通信過程中，接收SA的V2X終端通過SA指示的資料的位置資訊可以知道自身與發送SA的V2X終端之間的距離，如果距離小於距離門限值，認為該SA為衝突判斷SA。 In the embodiment of the present invention, the power threshold value Ps of the SA can be set. Only when the SA is correctly decoded and the received power of the SA exceeds the power threshold value Ps, the SA is considered to be a conflict judgment SA. For example, during the V2X communication process, the V2X sending terminal broadcasts its location information, so the V2X receiving terminal can count the minimum received power of the SA within the target communication range; or it can set the distance threshold of the SA. Only the SA is decoded correctly and the SA is sent. The distance between the V2X terminal and the V2X terminal receiving the SA is less than the distance threshold, and the SA is considered to be a conflict judgment SA. For example, in the V2X communication process, the V2X terminal receiving the SA can know the distance between itself and the V2X terminal sending the SA through the position information of the SA indicated material. If the distance is less than the distance gate Limit, consider this SA to be a conflict judgment SA.

如果V2X接收終端連續設定次數沒有接收到衝突判斷SA所指示的同一終端所發送的資料，則發送該終端的衝突資訊。 If the V2X receiving terminal does not receive the data sent by the same terminal indicated by the conflict determination SA for a set number of times, it sends conflict information of the terminal.

具體的，如果該V2X發送終端通過SA可用資源發送SA，以及通過資料可用資源發送資料之前，V2X發送終端作為V2X接收終端在接收到其他SA，且接收該其他SA的接收功率大於設定功率門限值或V2X發送終端與發送該其他SA的V2X終端之間的距離小於距離門限值，則確定接收的該其他SA為衝突判斷SA；該V2X發送終端在設定次數沒有成功接收到該衝突判斷SA對應的資料後，生成針對該衝突判斷SA的碰撞資訊。 Specifically, if the V2X sending terminal sends an SA through the available resources of the SA, and before sending data through the available resources of the data, the V2X sending terminal, as the V2X receiving terminal, receives other SAs, and the received power for receiving the other SA is greater than the set power threshold. Or the distance between the V2X sending terminal and the V2X terminal sending the other SA is less than the distance threshold, it is determined that the other SA received is a conflict judgment SA; the V2X sending terminal fails to receive the conflict judgment SA corresponding to the set number of times. After the data is generated, collision information for the conflict judgment SA is generated.

比如V2X發送終端作為接收終端在子訊框A上接收到了SA1，且接收SA1的接收功率大於設定功率門限值或V2X發送終端與發送該其他SA的V2X終端之間的距離小於距離門限值，則確定該SA1為衝突判斷SA；V2X發送終端如果設定次數都沒有成功接收到該SA1對應的資料，則生成針對該SA1的碰撞資訊。 For example, a V2X transmitting terminal receives SA1 on subframe A as a receiving terminal, and the receiving power of receiving SA1 is greater than a set power threshold or the distance between the V2X transmitting terminal and the V2X terminal transmitting the other SA is less than the distance threshold. It is determined that SA1 is a conflict judgment SA; if the V2X transmitting terminal fails to receive the data corresponding to the SA1 for a set number of times, it generates collision information for the SA1.

V2X發送終端在下次發送SA時，攜帶該SA1的碰撞資訊。其中攜帶該SA1的碰撞資訊的SA，可以是在V2X發送終端有資料需要發送時發送；也可以是沒有資料需要發送，只是為了通知發生碰撞的終端時發送。 The next time the V2X sending terminal sends SA, it will carry the collision information of SA1. The SA carrying the collision information of the SA1 may be sent when the V2X sending terminal has data to send, or it may be sent when there is no data to send, but only to notify the terminal that the collision occurred.

如果該碰撞資訊為SA指示的資源上發生碰撞的終端的個數；該V2X發送終端通過資料可用資源發送資料時，還通過資料可用資源發送發生碰撞的終端的終端標識。 If the collision information is the number of terminals that have collided on the resource indicated by the SA; when the V2X sending terminal sends information through the available resources, it also uses the available resources. Send the terminal ID of the terminal that collided.

比如V2X發送終端生成針對該SA1的碰撞資訊，並在V2X發送終端有資料需要發送時發送攜帶SA1的碰撞資訊的SA2；則V2X發送終端可以在承載SA2對應的資料的子訊框上發送該SA1的碰撞資訊對應的發生碰撞的終端的終端標識。 For example, the V2X transmitting terminal generates collision information for the SA1, and sends SA2 carrying the SA1 collision information when the V2X transmitting terminal has data to send; then the V2X transmitting terminal can send the SA1 on the sub-frame that carries the data corresponding to SA2. The terminal ID of the terminal where the collision occurred corresponding to the collision information of.
