A network node can receive one or more messages from a wireless communication node. The one or more messages can indicate a first set of TDD configuration parameters and a second set of TDD configuration parameters. The first set of TDD configuration parameters can be configured for a first link. The second set of TDD configuration parameters can be configured for a second link. ## Claims ### Claim 1 A wireless communication method, comprising: receiving, by a network node from a wireless communication node, one or more messages indicating a first set of Time Division Duplex (TDD) configuration parameters and a second set of TDD configuration parameters;
