Abstract

The method may include: after receiving, through a first interface or a second interface, resource allocation information of a neighboring cell of a serving cell in which UE is located, a network device may allocate a resource to the UE based on the resource allocation information of the neighboring cell, so as to prevent the UE from using a same resource as UE located in the neighboring cell, and reduce interference to the neighboring cell; or allocate, to the UE, a resource with relatively small interference to the UE, so as to reduce interference of the neighboring cell to the UE. The first interface is an interface that performs communication by using a UE-to-UE communications technology. The second interface is an interface that performs communication by using a UE-to-network device communications technology.

Claims16

Dependent claims

A network device, wherein the network device comprises:

a transceiver, configured to receive, through an interface, resource allocation information of a neighboring cell of a serving cell in which first UE is located, wherein a network device to which the neighboring cell belongs is different from the network device, the interface comprises a first interface or a second interface, the first interface is an interface that performs communication by using a UE-to-UE communications technology, and the second interface is an interface that performs communication by using a UE-to-network device communications technology;
and
a processor, configured to allocate a resource to the first UE based on the resource allocation information of the neighboring cell;
and, wherein receiving, by the transceiver through the interface, the resource allocation information of the neighboring cell of the serving cell in which the first UE is located comprises:
receiving, through the first interface, resource allocation information, sent by a second network device, of each cell managed by the second network device;
and triggering the processor to determine, from the resource allocation information of each cell, the resource allocation information of the neighboring cell of the serving cell in which the first UE is located.

UE, wherein the UE comprises:

a transceiver, configured to receive resource allocation information of a neighboring cell of a serving cell in which the UE is located, wherein a network device to which the neighboring cell belongs is different from a first network device connected to the UE;
and
the transceiver is further configured to report the resource allocation information of the neighboring cell to the first network device by using an interface, wherein the resource allocation information of the neighboring cell is used by the first network device to allocate a resource to the UE, the interface comprises a first interface or a second interface, the first interface is an interface that performs communication by using a UE-to-UE communications technology, and the second interface is an interface that performs communication by using a UE-to-network device communications technology;
and, wherein the UE further comprises:
a processor, configured to:
perform signal measurement on a reference signal sent by the first network device, to obtain a first measurement result and if the first measurement result is less than a first threshold, trigger the transceiver to perform the operation of reporting the resource allocation information of the neighboring cell to the first network device by using an interface.
