The patent is filed for a method of enabling enhanced multi-link communication modes
A recently filed patent (Publication Number: US20230319923A1) describes a method for enabling enhanced multi-link communication in wireless devices. The method involves the use of a first multi-link device (MLD) to enable either an enhanced multi-link single-radio (EMLSR) mode or an enhanced multi-link multi-radio (EMLMR) mode.
In this method, a first station (STA) affiliated with the first MLD receives an initial control frame from a second MLD in a first operating channel. The initial control frame indicates an allocated resource unit (RU). A second STA affiliated with the first MLD then switches from its second operating channel to the allocated channel where the allocated RU is located. During a transmission opportunity (TXOP), the second STA receives information from the second MLD on the allocated RU. The initial control frame includes a Secondary RU Allocation subfield that indicates the allocated RU.
The method also includes the receiving of a multi-user (MU) physical-layer protocol data unit (PPDU) by the second STA after a radio switching delay time of a subband operation. The allocated channel can be different from the first operating channel of the first STA.
The patent also describes a method for communication in an enhanced multi-link multi-radio (EMLMR) mode. In this method, the first MLD enables the EMLMR mode and the first STA receives a first initial control frame indicating a first allocated RU in its first operating channel. The second STA receives a second initial control frame indicating a second allocated RU in its second operating channel. The first STA communicates with the second MLD, receiving a first MU PPDU via the first allocated RU, while the second STA communicates with the second MLD, receiving a second MU PPDU via the second allocated RU. The initial control frames include Secondary RU Allocation subfields that indicate the allocated RUs within their respective operating channels.
The patent also includes an apparatus implementable in a first MLD, which includes a transceiver and a processor. The processor enables the EMLSR or EMLMR mode, receives initial control frames, switches operating channels, and receives information from the second MLD on the allocated RU.
Overall, this patent describes methods and apparatus for enabling enhanced multi-link communication in wireless devices, allowing for improved data transmission and resource allocation.
