Abstract
This application relates to the field of communications technologies, and discloses a resource configuration method and a node. The method includes: sending, by an parent node of a first node, first configuration information to the first node; and then determining, by the first node based on the first configuration information, a second resource for communication between the first node and a child node served by the first node. In this way, the determined second resource can implement orthogonalization between DMRS ports of an access link of the first node and a backhaul link of the first node, and therefore, link performance is improved.

A resource configuration method, comprising:
- receiving, by a first node, first configuration information sent by a second node, wherein the second node is a parent node of the first node;
- and
- determining, by the first node based on the first configuration information, a second resource for communication between the first node and a child node served by the first node, wherein the second resource is at least one demodulation reference signal (DMRS) port occupied by a first access link, the at least one DMRS port is one of a plurality of ports in a DMRS port set corresponding to a first slot, and the first access link is a link between the first node and the child node served by the first node,
- wherein the first node uses a space division multiple access (SDMA) technology that is based on flexible duplex.
A resource configuration method, comprising:
- determining, by a second node, first configuration information, wherein the first configuration information is used by a first node to determine, based on the first configuration information, a second resource for communication between the first node and a child node served by the first node, the second resource is at least one demodulation reference signal (DMRS) port that can be occupied by a first access link, the at least one DMRS port is one of a plurality of ports in a DMRS port set corresponding to a first slot, and the first access link is a link between the first node and the child node served by the first node;
- and
- sending, by the second node, the first configuration information to the first node,
