Resource configuration method and network device

A resource configuration method, wherein the method comprises:

• receiving, by a second node, first information and second information from a first node, wherein the first information indicates a resource multiplexing capability supported by one or more carriers of a mobile termination (MT) of the first node and one or more cells of a distributed unit (DU) of the first node, and wherein the resource multiplexing capability is a restricted resource multiplexing capability that is used when at least one condition is met, and wherein at least one condition of the restricted resource multiplexing capability comprises a maximum quantity of demodulation reference signal (DMRS) ports for downlink scheduling of the MT, a maximum quantity of DMRS ports for uplink scheduling of the MT, and an uplink transmit beam ID supported by the MT or a downlink receive beam ID supported by the MT, and wherein the second information indicates the at least one condition, and
• the resource multiplexing capability comprises a capability 1, a capability 2, a capability 3, and a capability 4, wherein the capability 1 indicates that the MT and the DU can send a signal simultaneously, the capability 2 indicates that the DU can receive a signal while the MT sends a signal, the capability 3 indicates that the DU can send a signal while the MT receives a signal, and the capability 4 indicates that the MT and the DU can receive a signal simultaneously.

A first node, wherein the first node comprises:

• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing programming instructions that when executed, cause the first node to perform operations comprising:
• sending first information and second information to a second node, wherein the first information indicates a resource multiplexing capability supported by one or more carriers of a mobile termination (MT) of the first node and one or more cells of a distributed unit (DU) of the first node, and wherein the resource multiplexing capability is a restricted resource multiplexing capability that is used when at least one condition is met, and wherein at least one condition of the restricted resource multiplexing capability comprises a maximum quantity of demodulation reference signal (DMRS) ports for downlink scheduling of the MT, a maximum quantity of DMRS ports for uplink scheduling of the MT, and an uplink transmit beam ID supported by the MT or a downlink receive beam ID supported by the MT, and wherein the second information indicates the at least one condition, and wherein the resource multiplexing capability comprises a capability 1, a capability 2, a capability 3, and a capability 4, wherein the capability 1 indicates that the MT and the DU can send a signal simultaneously, the capability 2 indicates that the DU can receive a signal while the MT sends a signal, the capability 3 indicates that the DU can send a signal while the MT receives a signal, and the capability 4 indicates that the MT and the DU can receive a signal simultaneously.

A second node, wherein the second node comprises:

• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing programming instructions that when executed, cause the second node to perform operations comprising:
• receiving first information and second information from a first node, wherein the first information indicates a resource multiplexing capability supported by one or more carriers of a mobile termination (MT) of the first node and one or more cells of a distributed unit (DU) of the first node, and wherein the resource multiplexing capability is a restricted resource multiplexing capability that is used when at least one condition is met, and wherein at least one condition of the restricted resource multiplexing capability comprises a maximum quantity of demodulation reference signal (DMRS) ports for downlink scheduling of the MT, a maximum quantity of DMRS ports for uplink scheduling of the MT, and an uplink transmit beam ID supported by the MT or a downlink receive beam ID supported by the MT, and wherein the second information indicates the at least one condition, and
• the resource multiplexing capability comprises a capability 1, a capability 2, a capability 3, and a capability 4, wherein the capability 1indicates that the MT and the DU can send a signal simultaneously, the capability 2indicates that the DU can receive a signal while the MT sends a signal, the capability 3 indicates that the DU can send a signal while the MT receives a signal, and the capability 4 indicates that the MT and the DU can receive a signal simultaneously.
