The patent application (Publication Number: US20240040620A1) describes a radio communication apparatus and method involving the setup of direct links between radio terminal apparatuses within a network. The apparatus includes a receiver for receiving reception frames and a transmitter for transmitting transmission frames. When information confirming direct link setup with a second radio terminal apparatus is received, the apparatus generates SR link information containing details of the involved radio terminal apparatuses and a color index. This SR link information is then transmitted to other radio terminal apparatuses within the network.

Furthermore, the patent application details the functionality of a first radio terminal apparatus within the network. This apparatus includes a transmitter and receiver for communication with the radio communication apparatus. The first radio terminal apparatus is responsible for transmitting information regarding the enabling of intra-BSS SR to the radio communication apparatus. It then receives SR link information, which includes details of other radio terminal apparatuses and a color index. Additionally, the first radio terminal apparatus is involved in direct link setup requests and confirmations with other radio terminal apparatuses, ensuring the proper configuration of direct links within the network based on the support for intra-BSS SR. The described methods and apparatus aim to enhance the efficiency and reliability of radio communication within a network by enabling direct links and managing intra-BSS SR capabilities effectively.
