In the embodiment of the present invention, the remote UE13 can establish a connection with the base station 11 through the D2D established with the relay UE12.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart of a method for configuring communication resources provided by an embodiment of the present invention. As shown in FIG. 2, it includes the following steps:

201. The relay UE receives a resource configuration message sent by a base station, where the resource configuration message carries resource information of at least two resource pools.

In this embodiment, the base station may establish a connection with the relay UE, and then send the resource configuration message through the connection. Of course, the base station may also send the above resource configuration message to the relay UE in a broadcast manner. In addition, the resource configuration message may include resource information of each resource pool in the at least two resource pools, for example: resource information of time-frequency resources of each resource pool. In addition, in this embodiment, the resource pool may be understood as a collection of at least one time-frequency resource.

202. The relay UE determines at least one resource pool from the at least two resource pools according to the resource information as a resource pool for the relay UE to transmit in D2D, where the at least two resource pools are not used The resource pool other than that transmitted by the relay UE is the resource pool for the remote UE to transmit in the D2D.

In this embodiment, after the relay UE acquires the above resource information, it may determine the above at least one resource pool as the resource pool for the relay UE to transmit in D2D according to the resource information. For example: the resource information includes indication information, and the indication information indicates that the at least one resource pool is a resource pool for the relay UE to transmit in D2D. In addition, the above resource information may not include indication information, and the relay UE may randomly determine at least one resource pool from the at least two resource pools as the resource pool for the relay UE to transmit in D2D according to the above resource information; Alternatively, the relay UE may randomly select at least one resource pool from the at least two resource pools as a resource pool for the relay UE to transmit in D2D according to the foregoing resource information and a preset selection rule.

It should be noted that, before performing step 202, the above-mentioned remote UE and the above-mentioned relay UE may not have established D2D, and the above steps only configure that the remote UE and the relay UE can use different resource pools when performing D2D. Send D2D data. Of course, before step 202 is performed, the above-mentioned remote UE may have established D2D communication with the relay.

Through the above steps, different resource pools can be configured for the relay UE and the remote UE, and configuring different resource pools can also solve the problem of resource competition between the remote UE and the relay UE, so as to improve the efficiency of the relay system in the resource pool mode. Under the communication performance.

In this embodiment, the above-mentioned relay UE may be a mobile phone, a tablet computer, an e-reader, a remote controller, a personal computer (PersonalComputer, PC), a notebook computer, a vehicle-mounted device, an Internet TV, a wearable device, and other smart devices with network functions. . The aforementioned remote UE may also be smart devices with network functions such as mobile phones, tablet computers, e-readers, remote controls, PCs, notebook computers, vehicle-mounted devices, Internet TVs, and wearable devices.

In this embodiment, the relay UE receives the resource configuration message sent by the base station, wherein the resource configuration message carries resource information of at least two resource pools; the relay UE selects the resource information from the at least two resource pools according to the resource information Determining at least one resource pool as the resource pool for the relay UE to transmit in D2D direct communication between terminals, wherein, among the at least two resource pools, the resource pool other than the resource pool used for the relay UE to transmit It is the resource pool for the remote UE to send in the D2D. D2D communication resources can be configured for the remote UE and the relay UE.

Please refer to FIG. 3. FIG. 3 is a schematic flowchart of another method for configuring communication resources provided by an embodiment of the present invention. As shown in FIG. 3, it includes the following steps:

301. A relay user terminal UE receives a resource configuration message sent by a base station, where the resource configuration message carries resource information of at least two resource pools.

In this embodiment, the above resource configuration message may be Radio Resource Control protocol (RadioResourceControl, RRC) signaling for configuring a resource pool, or the above resource configuration message may be an extended system information block (SystemInformationBlock, SIB), where the SIB message may It is sent to the relay UE in the form of broadcast. In addition, the above resource information may be identification information of the resource pool, or identification information of time-frequency resources in the resource pool, for example, frequency domain information or time domain information of the time-frequency resources. In addition, the above at least two resource pools may be the same in the frequency domain but different in the time domain, that is, the at least two resource pools may be the same in the frequency domain, but the at least two resource pools are located in Different time. Of course, the above at least two resource pools may be different resource pools in both the frequency domain and the time domain.

302. The relay UE determines at least one resource pool from the at least two resource pools according to the resource information as a resource pool for the relay UE to send in D2D direct communication between terminals, where the at least two The resource pools in the resource pools other than those used for the relay UE to transmit are resource pools for the remote UE to transmit in the D2D.

In this embodiment, the above at least one resource pool may be a part of the above at least two resource pools, and specifically may be one or more resource pools.

In addition, the above at least one resource pool may be selected by the relay UE based on the above resource information, for example: Step 302 may include:

The relay UE selects at least one resource pool from the at least two resource pools as a resource pool for the relay UE to transmit in D2D according to the resource information and the information of the remote UE.

Wherein, the above-mentioned remote UE information may include the number of remote UEs, and may also include the air interface (for example: Un interface) interference of the remote UEs, etc., for example: when the number of remote UEs is large (for example: many ), the relay UE may select one of the above at least two resource pools as the resource pool for the relay UE to transmit in D2D; or when the air interface interference level of the remote UE is very high, the relay The UE may select one of the above at least two resource pools as the resource pool for the relay UE to transmit in D2D, so as to ensure that as many resource pools as possible are configured for the remote UE. Specifically, the relay UE may pre-obtain a configuration strategy for configuring the resource pool for the relay UE to transmit in D2D, so that step 302 may configure different resource pools for the relay UE and the remote UE based on the configuration strategy.

In addition, in this embodiment, the above method may also include the following steps:

The relay UE sends an indication message to the remote UE, where the indication message is used to indicate that the at least one resource pool is a resource pool for the relay UE to transmit in D2D, and indicate that the at least two resource pools The resource pools other than those used for transmission by the relay UE are resource pools for the remote UE to transmit in the D2D.

Specifically, after the relay UE selects a resource pool for the relay UE to transmit in D2D, the relay UE can configure other resource pools in the above at least two resource pools to the remote UE. Therefore, the above indication message can be used to inform the remote UE of the resource pool for sending in the D2D, and tell the remote UE the resource pool for the relay UE to send in the D2D. In this way, the remote UE can send and receive D2D data on the corresponding resource pool, and similarly, the relay UE can also send and receive D2D data on the corresponding resource pool.

In this implementation manner, when the foregoing remote UEs are multiple UEs, the relay UE may configure different resource pools for the multiple remote UEs according to conditions of each remote UE. For example, resource pools with different numbers or different interference characteristics can be configured for multiple remote UEs according to the location of each remote UE. Resource pools with better interference characteristics; for example, resource pools with different numbers or different interference characteristics can be configured for multiple remote UEs according to the air interface interference of each remote UE, such as the number of remote UEs with higher interference levels. More resource pools or resource pools with better interference characteristics.

In addition, in this embodiment, the above method may also include the following steps:

The relay UE configures, for the remote UE, a resource pool for the remote UE to transmit in the D2D;

Wherein, the indication message carries the configured valid time and the resource information of the resource pool for the relay UE to transmit in the D2D. Wherein, in addition, the valid time of the above configuration may be understood as the valid time of the configuration of the resource pool that the remote UE transmits in the D2D, and the valid time may be understood as a valid duration.

In addition, the above resource pool for the relay UE to transmit in the D2D and the resource pool for the remote UE to transmit in the D2D are staggered in time domain. In this way, only the remote UE or the relay UE has half-duplex constraints, that is, the same terminal can only perform receiving or transmitting operations at the same time, and cannot perform receiving or transmitting operations at the same time. Therefore, the allocated resource pool is in Staggering in the time domain can avoid the situation that the relay UE and the remote UE transmit at the same time, so that the transmitted data cannot be received. Specifically, as shown in FIG. 4 , the resource pool for the remote UE to transmit in the D2D and the resource pool for the relay UE to transmit in the D2D are staggered in time domain.

In addition, in the above implementation manner, the remote UE may be a UE outside the network coverage of the base station, or a UE that cannot establish a connection with the base station. And the communication between the relay UE and the remote UE may use a D2D dedicated interface. For example, the above sending of the indication message may be sending the indication message to the remote UE through the PC5 interface.

In this embodiment, the resource information of the at least two resource pools includes first indication information indicating that the at least one resource pool is used as a resource pool for the relay UE to transmit in the D2D, and includes indicating that the at least Among the two resource pools, the resource pools other than those used for transmission by the relay UE are the second indication information of the resource pools for the remote UE to transmit in the D2D.

For example: the resource information of each resource pool includes the sending resource pool indicating which UE the resource pool is used for, so that through the resource information of each resource pool, it can be known which resource pools are used as the resources for the relay UE to transmit in the D2D pools, and which resource pools are used as the resource pools for the remote UE to send in the D2D, that is, the above-mentioned first indication information includes the indication information in the resource information of the above-mentioned at least one resource pool, and similarly, the above-mentioned second indication information includes Indication information in resource information of resource pools other than the at least one resource pool among the at least two resource pools. Certainly, the above-mentioned first indication information and second indication information may also exist independently.

In addition, step 302 in this implementation manner may include:

The relay UE determines from the at least two resource pools according to the first indication information that the at least one resource pool is a resource pool for the relay UE to transmit in D2D.

In this embodiment, the base station can directly configure the resource pool for the relay UE to transmit in D2D and the resource pool for the remote UE to transmit in D2D. In addition, in this embodiment, the resource configuration message received in step 301 will also be sent to the remote UE, that is, both the relay UE and the remote UE will receive the above resource configuration message, so as to determine their respective resource pools for sending, and The resource pool for sending by the other party is also determined, so that data can be sent and received on the corresponding resource pool. In addition, the foregoing remote UE may also be a UE within the network coverage of the base station.

In this implementation manner, the above resource information further includes valid time information of the resource pool. In addition, the valid time information here can be understood as configured valid time information. In this way, it can be realized that the effective time of configuration of the resource pools of the remote UE and the relay UE is determined by the base station.

In addition, the resource pool for the relay UE to transmit in the D2D and the resource pool for the remote UE to transmit in the D2D may be staggered in time domain. In this way, only the remote UE or the relay UE has half-duplex constraints, that is, the same terminal can only perform receiving or transmitting operations at the same time, and cannot perform receiving or transmitting operations at the same time. Therefore, the allocated resource pool is in Staggering in the time domain can avoid the situation that the relay UE and the remote UE transmit at the same time, so that the transmitted data cannot be received.

In this embodiment, the above method may also include the following steps:

303. The relay UE sends D2D data to the remote UE by using resources in the at least one resource pool.

304. The relay UE receives the D2D data sent by the remote UE using the resources in the resource pool where the remote UE sends in the D2D.

After step 302 determines the resource pool of the relay UE for transmission, the relay UE can use the resources in the resource pool to send D2D data to the remote UE, and the remote UE can also determine the resource pool of the relay UE for transmission , so that the D2D data sent by the relay UE can be received on the corresponding resource pool. For example, after the relay UE has determined the resource pool for transmission, the relay UE can send a message to tell the remote UE the resource pool for transmission determined by the relay UE. The remote UE sends an indication message. Or indicated by the base station in the above resource configuration message. Similarly, the relay UE may also determine the resource pool for sending by the remote UE, so as to receive the D2D data sent by the remote UE on the corresponding resource pool.

In this embodiment, multiple optional implementation manners are added on the basis of the embodiment shown in FIG. 2 , and all of them can implement configuring D2D communication resources for the remote UE and the relay UE.

In this way, the resource configuration information sent by the base station can determine the resource pool for the remote UE to send and the resource pool for the relay UE to send. In addition, in this implementation manner, the above resource configuration information may be sent to the remote UE and the relay UE. In this way, both the remote UE and the relay UE know the resource pools for sending by themselves and the other party, so that they can send in the corresponding resource pools.

In addition, the above indication information may also carry valid time information of each resource pool in the at least two resource pools.

The remote UE receives the resource configuration information sent by the relay UE.

In addition, in this embodiment, the above-mentioned resource configuration information may also include information about the resource pool that the relay UE transmits in D2D, that is, the resource configuration information may be used to inform the remote UE of the resource pool that the relay UE transmits in D2D, In this way, the remote UE can receive the D2D data sent by the relay UE on these resource pools.

In addition, in this embodiment, the above resource configuration information may also carry the effective time of configuration of the at least one resource pool and the resource information of the resource pool that the relay UE transmits in the D2D.

In this embodiment, in the above two implementation manners, the resource pool for the remote UE to transmit in the D2D and the resource pool for the relay UE to transmit in the D2D are staggered in time domain.
