Layer 2 function (link layer function), such as wireless MAC frame function) or L1+L2+L3 (L3 is layer 3 function for wireless communication (network layer) Function), such as wireless PDCP function, etc., its superior node completes other parts of the wireless function (such as the radio node only completes the L1 function, the upper node completes the L2+L3 function), and the upper node completes the control function of the radio node at the same time. One end of the radio frequency node and its upper node group wireless communication system communicates wirelessly with the other end wireless transceiver 2.

需要说明的是，在图1所示的场景中，射频节点可以是发送节点，也可以是接收节点，上级节点也可以是发送节点或者接收节点，即：如果射频节点可以向上级节点发送数据，则上级节点为接收节点，射频节点为发送节点；如果上级节点向射频节点发送数据，则上级节点为发送节点，射频节点为接收节点。It should be noted that, in the scenario shown in FIG. 1, the radio frequency node may be a sending node or a receiving node, and the upper node may also be a sending node or a receiving node, that is, if the radio frequency node can send data to the upper node, Then, the upper node is a receiving node, and the radio node is a transmitting node; if the upper node sends data to the radio node, the upper node is a sending node, and the radio node is a receiving node.
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.
本申请实施例公开的一种数据传输方法，本实施例中，上级节点和射频节点之间通过传输层传输数据，即无论哪一方作为发送方，发送方发送的数据均为传输层数据。A data transmission method disclosed in the embodiment of the present application, in this embodiment, data is transmitted between a superior node and a radio frequency node through a transport layer, that is, no matter which side is the sender, the data sent by the sender is the transport layer data.
如图2所示，本实施例所述的方法包括以下步骤： As shown in FIG. 2, the method described in this embodiment includes the following steps:
S201：发送节点从第一范围内确定待传输数据的类型；S201: The sending node determines, according to the type of data to be transmitted, the first range.
其中，第一范围包括：传输控制数据、传输同步数据、传输用户数据和传输维护管理数据这几种数据类型。需要说明的是，第一范围中的数据类型仅为本实施例的一种具体情况，第一范围还可以依据其它分类标准进行设定，本申请实施例不做限定。The first range includes: data transmission control data, transmission synchronization data, transmission user data, and transmission maintenance management data. It should be noted that the data type in the first range is only a specific case of the embodiment, and the first range may also be set according to other classification standards, which is not limited in the embodiment of the present application.
S202：发送节点依据预设的对应关系及所述待传输数据的类型，将所述待传输数据按照优先级由高到低进行排序；S202: The sending node sorts the to-be-transmitted data according to a priority from high to low according to a preset correspondence relationship and a type of the data to be transmitted.
其中，所述对应关系为数据类型与传输优先级的对应关系。也就是说，传输类型1、传输类型2、……传输类型n分别对应不同的优先级。The corresponding relationship is a correspondence between a data type and a transmission priority. That is to say, the transmission type 1, the transmission type 2, ... the transmission type n respectively correspond to different priorities.
具体地，对于传输层数据，传输控制数据和传输同步数据对应高优先级，传输用户数据和传输维护管理数据对应低优先级。Specifically, for the transport layer data, the transmission control data and the transmission synchronization data correspond to a high priority, and the transmission user data and the transmission maintenance management data correspond to a low priority.
S203：发送节点按照排序结果指示的顺序，依次发送各个待传输数据。S203: The sending node sequentially sends each data to be transmitted in the order indicated by the sorting result.
具体地，发送节点按照排序结果指示的顺序，将待传输数据发送到传输***中，传输***按照待传输数据的接收顺序，将待传输数据发送到接收节点。Specifically, the sending node sends the data to be transmitted to the transmission system in the order indicated by the sorting result, and the transmitting system sends the data to be transmitted to the receiving node according to the receiving order of the data to be transmitted.
本实施例所述的数据传输方法，发送节点依据待发送数据的类型，确定各个待发送数据的发送优先级，再按照优先级由高到低的顺序，发送待发送数据，因此，能够保证高优先级的数据优先发送，所以，使得高优先级的数据优先占用网络，所以，在网络质量不变的情况下，能够提高数据的传输质量。In the data transmission method of the embodiment, the sending node determines the sending priority of each data to be sent according to the type of the data to be sent, and then sends the data to be sent according to the order of priority from high to low, thereby ensuring high Priority data is sent preferentially, so that high-priority data is preferentially occupied by the network, so that the quality of data transmission can be improved without changing the network quality.
本申请实施例公开的又一种数据传输方法，本实施例中，上级节点和 无线收发器2之间通过射频节点中转传输无线层数据，即无论哪一方作为发送方，发送方发送的数据均为无线层数据。Another data transmission method disclosed in the embodiment of the present application, in this embodiment, the upper node and The wireless transceiver 2 transmits the wireless layer data through the radio frequency node, that is, whether the sender is the sender or not, the data transmitted by the sender is the wireless layer data.

S301：发送节点从第二范围内确定待传输数据的类型；S301: The sending node determines, according to the second range, a type of data to be transmitted.
本实施例中，第二范围包括不同的传输用户类型数据。也就是说，本实施例中，依据传输用户类型对数据进行分类。In this embodiment, the second range includes different transmission user type data. That is to say, in this embodiment, the data is classified according to the type of the transmission user.
S302：发送节点依据传输用户类型与优先级间的对应关系，确定待传输数据的优先级；S302: The sending node determines the priority of the data to be transmitted according to the correspondence between the transmission user type and the priority.
对于无线层数据，不同的传输用户类型可以对应不同的优先级。例如，传输用户1对应高优先级，传输用户2对应低优先级。For wireless layer data, different transmission user types can correspond to different priorities. For example, the transmission user 1 corresponds to a high priority, and the transmission user 2 corresponds to a low priority.
S303：发送节点按照确定出的优先级，为每个待传输数据设置优先级标识；S303: The sending node sets a priority identifier for each data to be transmitted according to the determined priority.
例如，高优先级设置标识1，低优先级设置标识0。For example, the high priority setting identifies 1 and the low priority setting identifies 0.
S304：发送节点依据优先级的标识，将待传输数据按照优先级由高到低进行排序；S304: The sending node sorts the data to be transmitted according to the priority from high to low according to the identifier of the priority.
S305：发送节点按照排序结果，发送待传输数据。S305: The sending node sends the data to be transmitted according to the sorting result.
具体地，传输***接收到待传输数据后，可以按照数据携带的标识，将数据按照优先级的高低顺序进行发送。Specifically, after receiving the data to be transmitted, the transmission system may send the data according to the priority of the priority according to the identifier carried by the data.
本实施例中所述的方法，可以优先发送优先级高的无线层数据，从而提高数据的传输质量。The method described in this embodiment can preferentially transmit wireless layer data with high priority, thereby improving data transmission quality.
本申请实施例公开的又一种数据传输方法，应用在多小区的无线通信 场景中，如图4所示，射频节点1和射频节点2可以是两个独立的节点，也可以是同一个节点。无线收发器2和无线收发器3可以是两个独立的节点，也可以是同一个节点，无线收发器2、3通过小区1、2分别接入到射频节点1、2。Another data transmission method disclosed in the embodiment of the present application is applied to wireless communication in multiple cells In the scenario, as shown in FIG. 4, the radio node 1 and the radio node 2 may be two independent nodes or the same node. The wireless transceiver 2 and the wireless transceiver 3 may be two independent nodes or the same node, and the wireless transceivers 2, 3 are respectively connected to the radio frequency nodes 1, 2 through the cells 1 and 2.
如图5所示，本实施例所述的方法包括以下步骤：As shown in FIG. 5, the method described in this embodiment includes the following steps:
S501：发送节点确定待传输数据所属的小区；S501: The sending node determines a cell to which the data to be transmitted belongs;
例如，确定待传输数据属于小区1还是小区2。For example, it is determined whether the data to be transmitted belongs to cell 1 or cell 2.
S502：发送节点依据小区数据与不同的优先级间的对应关系，将待传输数据按照优先级高低进行排序；S502: The sending node sorts the data to be transmitted according to the priority according to the correspondence between the cell data and different priorities.
S503：发送节点按照排序结果，发送待传输的数据。S503: The sending node sends the data to be transmitted according to the sorting result.
可见，本实施例中所述的方法，可以按照小区确定待发送数据的优先级，从而保证重点小区的数据传输质量。It can be seen that, in the method described in this embodiment, the priority of the data to be sent can be determined according to the cell, thereby ensuring the data transmission quality of the key cell.
需要说明的是，本实施例所述的按照小区确定数据优先级的方式，可以与上述实施例中所述的传输层数据以及无线层数据的优先级的确定方式结合使用。It should be noted that the manner of determining the data priority according to the cell in this embodiment may be used in combination with the manner of determining the priority of the transport layer data and the radio layer data in the foregoing embodiment.
需要说明的是，数据按照以上不同的分类原则，优先级可以出现交错，在优先级交错的情况下，可以规定以哪个分类原则确定的优先级为主，例如，高优先小区的低优先级传输层数据的优先级可以低于低优先级小区的高优先级传输层数据。It should be noted that, according to the above different classification principles, the priority may be interleaved. In the case of priority interleaving, the priority determined by which classification principle may be specified, for example, the low priority transmission of the high priority cell. The priority of the layer data may be lower than the high priority transport layer data of the low priority cell.
除了上述对于发送节点的发送方式的限定外，本申请中，对于数据的 接收节点，同样可以采用利用优先级接收数据的方式，具体地，本申请实施例公开的又一种数据传输方法，包括以下步骤：In addition to the above limitation on the manner of transmission of the transmitting node, in the present application, for data The receiving node may also adopt a method of receiving data by using a priority. Specifically, another data transmission method disclosed in the embodiment of the present application includes the following steps:
A：接收节点接收数据，并按照第一顺序对接收到的数据进行处理。A: The receiving node receives the data and processes the received data in the first order.
其中，第一顺序为发送节点发送数据的顺序。也就是说，发送节点按照什么顺序发送数据，接收节点即按照什么顺序处理数据。本实施例中，处理可以包括：存储、解调、转发等。The first sequence is the order in which the sending node sends data. That is to say, in what order the sending node sends data, and the receiving node processes the data in what order. In this embodiment, the processing may include: storing, demodulating, forwarding, and the like.
具体地，发送节点为待发送数据设置优先级标志后，依据标识，按照优先级由高到低的顺序，依次发送数据，传输***也按照数据的标识，转发数据，接收节点同样按照数据的标识处理接收到的数据。Specifically, after the sending node sets the priority flag for the data to be sent, according to the identifier, the data is sequentially transmitted according to the order of priority from high to low, and the transmission system also forwards the data according to the identifier of the data, and the receiving node also follows the identifier of the data.

第二顺序为接收节点依据数据类型与优先级的对应关系，对待接收数据进行排序后得到的顺序，也就是说，接收节点本地有一套对应关系，接收节点确定待接收数据的类型，并依据对应关系对待接收数据按照优先级进行排序，按照排序结果，处理接收到的数据。The second sequence is the order in which the receiving node sorts the data to be received according to the correspondence between the data type and the priority, that is, the receiving node has a corresponding correspondence locally, and the receiving node determines the type of the data to be received, and according to the corresponding The relationship treats the received data by priority, and processes the received data according to the sort result.
其中，接收节点本地的对应关系与接收方使用的对应关系不同，具体地，所述第一对应关系中至少包括一种数据类型，此数据类型在所述第一对应关系中对应的优先级与在所述第二对应关系中对应的优先级不同。The corresponding relationship between the locality of the receiving node and the corresponding relationship used by the receiving party is different. Specifically, the first corresponding relationship includes at least one data type, and the corresponding priority of the data type in the first corresponding relationship is The corresponding priorities in the second correspondence are different.
本实施例中所述的接收节点处理接收到的数据的方法，同样能够提高数据传输的质量。The method in which the receiving node described in this embodiment processes the received data can also improve the quality of data transmission.
