Embodiment 2

The embodiment provides a method for resource scheduling, and the performing entity of the method may be all RNs that have established a connection with the base station. The method includes:

Step F1: acquiring related information of the terminal connected to the relay node communication;

The related information of the terminal connected to the relay node communication includes: the number of terminals connected to the relay node, the feeling of the terminal connected to the relay node, and the link between the relay node and the terminal The throughput is any one or any combination of more than one.

Step F2: Send the obtained related information of the terminal that is connected to the relay node to the base station, so that the base station performs the relay node according to the related information of the terminal that is connected to the relay node. Resource Scheduling.

It should be noted that, in the specific step F2, the specific scheme for the base station to perform resource scheduling on the relay node is: assigning the highest priority to the relay node with the largest number of UEs connected to the relay node, and/or The UE connected to the node communication provides the best perceived relay node to assign the highest priority, and/or assigns the highest priority to the relay with the highest throughput of the link between the relay node and the terminal. The higher the priority of the eNB The relay node allocates relatively more radio resources.

With the resource scheduling method provided by the embodiment, the relay node sends the acquired information about the UE connected to the relay node to the base station, so that the base station performs resource scheduling on the relay node that establishes a connection with the base station. It is more reasonable for the base station to schedule the relay node that establishes a connection with the base station, and the QoS of the communication system is improved compared with the prior art. Embodiment 3

This embodiment provides a resource scheduling method, which is a more detailed implementation based on the first embodiment. The method for resource scheduling provided in this embodiment is applicable to a Long Term Evolution (LTE) wireless system, but is not limited to the LET system. As shown in FIG. 2, the method includes:

Step A1: The relay node acquires related information of the UE connected to its own communication;

It should be noted that the related information of the UE that is connected to the relay node in step A1 may include: the number of UEs that are in communication with the relay node, and the feelings of the UE that is connected to the relay node, the relay node and Any one or more of any combination of throughputs of links between UEs. It should be noted that the throughput of the link between the relay node and the UE may be represented by the success rate of data transmission between the relay node and the terminal, or may be represented by the number of successful bits of data transmitted between the relay node and the terminal. It should be understood that the representation parameter of the throughput of the link between the relay node and the UE is not limited to the above two descriptions.

Step A2: The relay node sends related information of the UE connected to its own communication to the eNB;

The RN can pass the upper 4 buffer status report (BSR, Buffer Status Report) ^eNB, The BSR includes related information of the UE connected to the RN, and the RN may also carry information related to the UE connected to the RN through a Media Access Control (MAC) message in the eNB communication, and the RN also The information related to the UE connected to the RN communication may be transmitted to the eNB through an Extended Radio Resource Control (RRC) information element. The specific operation method of the RN transmitting the related information of the UE that is connected to the eNB to the eNB is not limited. The foregoing example should not be construed as limiting the technical solution.

Step A3: After receiving the information about the UE that is connected to the relay node and sent by the relay node, the eNB performs resource scheduling on the relay node according to the related information of the UE that is connected to the relay node.

For example, in order to more clearly understand the resource scheduling performed by the eNB in step A3 according to the information about the UE that is connected to the relay node, the following specific operations are as follows: The related information of the UE connected by the node communication only includes: the throughput of the link between the relay node and the terminal, and the eNB generally assigns the highest priority to the relay station with the highest throughput of the link between the relay node and the terminal, so that the eNB The maximum throughput RN of the link between the relay node and the terminal is allocated more radio resources than other RNs.

When the eNB acquires the number of UEs that are in communication with the relay node, the UE's perception of the communication with the relay node, and the throughput of the link between the relay node and the terminal, the eNB usually satisfies the following The conditional relay node assigns a higher priority to allocate more radio resources. The relay node needs to have the following conditions: The number of UEs connected to the relay node is the largest and communicates with the relay node. The UE feels the best, and the throughput of the link between the relay node and the terminal is the largest. In fact, in many cases, the relay node with the highest priority cannot satisfy the above conditions. The eNB can select a reasonable priority level for each RN according to a specific algorithm, thereby allocating reasonable resources to each RN, and performing resources on the relay node. Scheduling. The specific algorithm may refer to an algorithm for allocating resources for a UE in the prior art, and may also have other algorithms. When the eNB receives the number of UEs that are in communication with the relay node, the UE's experience of communicating with the relay node, or any one or any combination of the throughputs of the link between the relay node and the terminal, The resource scheduling of the RN has a similar description of the algorithm.

The related information of the UE that is connected to the relay node and received by the eNB includes only: When the number of UEs connected to the point is connected, the eNB usually assigns the highest priority to the RNs with the largest number of serving UEs, thereby allocating more radio resources than the other RNs for the RNs having the largest number of serving UEs.

Similarly, when the related information of the UE that is connected to the relay node and is connected to the relay node only includes: the feeling of the UE connected to the relay node, the eNB usually assigns the highest priority to the RN that makes the UE feel the best. Therefore, more RNs are allocated than other RNs for the RNs that have the best experience of the UE.

It should also be noted that, before step A3, the method may further include:

Step A4: The eNB acquires the throughput of the link between the RN and itself.

In step A4, the specific implementation method for obtaining the throughput of the link between the RN and the self may be: storing the success rate of transmitting data with the RN in the eNB, or the number of successful bits of the transmitted data, thereby acquiring the RN and the self. The throughput of the link between the RN and the self may be acquired in the eNB according to the calculation.

It should be noted that, in step A3, the eNB performs resource scheduling on the relay node according to the received information about the terminal connected to the relay node and the acquired throughput of the link between the relay node and the eNB. .

If the received information about the terminal connected to the relay node communication includes: the throughput of the link between the relay node and the terminal, and the eNB acquires the throughput of the link between the relay node and itself, the eNB The throughput of the two links of the UE to the RN and the RN to the eNB is comprehensively considered, and each RN is allocated a reasonable resource. A specific scheduling algorithm may be: adding the throughputs of the two links of the UE to the RN and the RN to the eNB, and the RN on the addition and the largest link has the highest priority, so that the eNB allocates the RN. The most resources.

The above exemplifies four possible eNB operations on RN resource scheduling, which are not exhaustive, and can be easily implemented according to the above principles for other situations.

Through the description of the foregoing steps A1 to A4, the method implements that the eNB receives related information of the UE that is connected to the relay node, and performs resource scheduling on the RN according to the related information of the UE that is connected to the relay node. The operation makes it more reasonable for the eNB to schedule the relay node that establishes a connection with the base station, and improves the communication quality compared with the prior art.

As shown in FIG. 4, the existing 3-byte long BSR is extended to 4 bytes or more, and the UE number information is added, where the UE number information occupies 1 bit, and the logical channel 0 (LCG0) to the most serviced in LCG3 The number of UEs in the logical channel of the number of UEs is indicated as the number of UEs. The number of UEs that can be carried by each logical channel can also be carried in the long BSR, as shown in FIG. 5. It is also possible to increase the indication of the UE experience in the long BSR, specifically by adding 1 bit or more to the BSR, and each code represents a feeling, such as 1 for satisfaction and 0 for dissatisfaction. The UE experience information in the BSR sent by the RN to the eNB is not a feeling of a certain UE, but a comprehensive evaluation of all UEs connected by the RN communication.
