When the terminal selects the transmission resource from the resource pool, the specific transmission resource is selected from the resource pool corresponding to the unicast service for the unicast service, and the specific transmission resource is selected from the resource pool corresponding to the multicast/broadcast service for the multicast/broadcast service.

When the terminal is a direct communication receiving end, the terminal can acquire a resource pool configured or pre-configured by the network side equipment, acquire a data transmission mode corresponding to the configured resource pool, and receive data by adopting resources in the corresponding resource pool according to the data transmission mode of the direct communication link.

According to the above, with the method for scheduling resources of a direct communication link according to the embodiment of the present invention, when the terminal is a direct communication link sending end, a resource allocation manner of network scheduling may be utilized, and when a network side device allocates resources for the direct communication link of the terminal, a data transmission manner corresponding to the resources for direct communication link allocation is indicated.

For example, when the terminal is a direct communication link sending end, a specific process when a direct communication interface of the terminal has a data transmission requirement may be:

the terminal reports the Sidelink related auxiliary information to the network side equipment;

after receiving the Sidelink-related auxiliary information reported by the terminal, the network side equipment judges whether dynamic scheduling or semi-persistent scheduling is adopted; if dynamic scheduling is used, when allocating resources to the direct communication link, the network side device needs to indicate whether the resources are for a unicast service or a multicast/broadcast service, and the specific indication manner may be: when the network side equipment allocates resources for the direct communication link, distinguishing whether the scheduling signaling aims at the Silelink unicast service or the multicast/broadcast service through different SL-RNTIs corresponding to the resource scheduling signaling;

After receiving the resource scheduling signaling, the terminal judges whether the resource scheduled by the network side equipment for the direct communication link is for the Sidelink unicast or multicast/broadcast service according to the SL-RNTI, and further can judge which direct communication target end the resource for the direct communication link is applied to, and then performs data packet organization according to the judgment, and performs data transmission.

In another embodiment, when the network side device receives the Sidelink-related auxiliary information reported by the terminal and determines to adopt dynamic scheduling, the network side device needs to indicate whether the resource is directed to a unicast service or a multicast/broadcast service when allocating the resource to the direct communication link, and the specific indication mode may also be:

when the network side allocates resources for the direct communication link, indicating whether the scheduling signaling aims at the Sidelink unicast or multicast/broadcast service through the indication information carried in the PDSCH scheduled by the scheduling signaling or the SL-RNTI. And when the terminal communicates with multiple direct communication targets at the same time, in order to further identify the corresponding relationship between the resources and the communication targets, the scheduling signaling for the direct communication link or the PDSCH indicated by the scheduling signaling also needs to carry communication target indication information.

the time/frequency resources which can be used by the Sidelink unicast and the multicast/broadcast are separated, and when the network side allocates the resources for the direct communication link, the network side indicates whether the scheduling signaling aims at the Sidelink unicast or the multicast/broadcast service through the allocated specific resources. And if the terminal communicates with a plurality of direct communication targets at the same time, in order to further identify the corresponding relationship between the resources and the communication targets, the scheduling signaling for the direct communication link or the PDSCH indicated by the scheduling signaling also needs to carry communication target indication information.

In another embodiment, when the network side device receives the Sidelink-related auxiliary information reported by the terminal and determines to adopt the semi-persistent scheduling, the network side device needs to indicate whether the resource is directed to a unicast service or a multicast/broadcast service when allocating the resource to the direct communication link, and the specific indication manner may also be:

the network side equipment carries type indication information in configuration signaling (RRC signaling) of semi-persistent scheduling to indicate whether each semi-persistent scheduling configuration aims at Sidelink unicast or multicast/broadcast service.

If the terminal communicates with a plurality of direct communication targets at the same time, in order to further identify the corresponding relationship between the resources and the communication targets, the configuration signaling of the semi-persistent scheduling may also carry indication information of the communication targets for each semi-persistent scheduling configuration.

The terminal receives the configuration signaling of the semi-persistent scheduling, determines whether the resource corresponding to the semi-persistent scheduling aims at the Sidelink unicast or multicast/broadcast service according to the indication information carried in the configuration signaling of the semi-persistent scheduling, and further can judge which direct communication target end the resource aims at. And then, organizing the data packet according to the data packet.

the network side equipment carries type indication information in a PDCCH activation signaling corresponding to the semi-persistent scheduling to indicate whether each semi-persistent scheduling configuration aims at Sidelink unicast or multicast/broadcast service.

If the terminal communicates with multiple direct communication targets at the same time, in order to further identify the corresponding relationship between the resources and the communication targets, the PDCCH activation signaling or the PDSCH indicated by the PDCCH activation signaling also needs to carry communication target indication information.

After receiving the PDCCH activation signaling corresponding to the semi-persistent scheduling, the terminal determines whether the resource corresponding to the semi-persistent scheduling is for the Sidelink unicast or multicast/broadcast service according to the indication information carried in the PDCCH activation signaling corresponding to the semi-persistent scheduling, and further can determine which direct communication target terminal the resource corresponds to. And then, organizing the data packet according to the data packet.

In another embodiment, when the network side device receives the Sidelink-related auxiliary information reported by the terminal and determines to adopt the semi-persistent scheduling, the network side device needs to indicate whether the resource is directed to the unicast service or the multicast/broadcast service when allocating the resource to the direct communication link, and the specific indication manner may also be:

the time/frequency resources which can be used by the Sidelink unicast and the multicast/broadcast are separated, and the network side indicates whether the semi-persistent scheduling aims at the Sidelink unicast or multicast/broadcast service through specific resources allocated in the configured PDCCH activation signaling of the semi-persistent scheduling.

If the terminal communicates with a plurality of direct communication targets at the same time, in order to further identify the corresponding relationship between the resources and the communication targets, the PDCCH activation signaling for the direct communication link may also carry communication target indication information.

After receiving the PDCCH activation signaling corresponding to the semi-persistent scheduling, the terminal determines whether the resource corresponding to the semi-persistent scheduling is for the Sidelink unicast or multicast/broadcast service according to the specific resource allocated in the PDCCH activation signaling configured for the semi-persistent scheduling, and further can determine which direct communication target terminal the resource corresponds to.
