Method for performing channel usage management with aid of multi-link operation architecture, and associated apparatus

A wireless transceiver device, for performing channel usage management with aid of multi-link operation (MLO) architecture, the wireless transceiver device being one of multiple devices within a wireless communications system, the wireless transceiver device comprising:

• a processing circuit, arranged to control operations of the wireless transceiver device;
• and
• at least one communications control circuit, coupled to the processing circuit, arranged to perform communications control, wherein the at least one communications control circuit is arranged to perform wireless communications operations with another device among the multiple devices for the wireless transceiver device;
• wherein:
• the wireless transceiver device is arranged to communicate with the other device within the wireless communications system through at least one portion of multiple links respectively corresponding to multiple predetermined radio frequency bands;
• and
• at a first time point when radar is detected in a first channel used by a first link among the multiple links, the wireless transceiver device is arranged to start performing a first procedure to make channel management information be received by the other device via one or more other links among the multiple links at any time point when the other device is ready to receive the channel management information, wherein the first channel is one of multiple channels of a first predetermined radio frequency band among the multiple predetermined radio frequency bands, and the other device is not ready to receive the channel management information at the first time point.
