The invention discloses a PS ratio control system and method for optimizing SWIPT multi-hop relay throughput, the system comprises a source node, the source node forwards information to a destination node hop by hop through a relay set, and the source node is powered by an internal battery or an external power supply; the relays all work in a passive state; energy is collected from a radio frequency signal of a previous hop adjacent node of the relay node by adopting an SWIPT technology, and decoding of a data packet and forwarding of the data packet to a next hop adjacent node are completed at the same time by utilizing a power distribution (PS) protocol; the power distribution ratio, namely the PS ratio, is set as follows: the radio frequency signal at the relay node is divided into two paths, one part is used for energy collection, and the other part is used for information decoding.

A method and apparatus for preventing unnecessary NPCA by delivering NPCA mode via a management frame in a wireless LAN system are proposed. Specifically, a receiving STA receives a first management frame from a transmitting STA. The receiving STA transmits a second management frame to the transmitting STA. The receiving STA determines whether to perform channel access for a first non-primary channel based on the first management frame and the second management frame. The first management frame includes a first NPCA mode, which is information about whether the transmitting STA performs channel access for the first non-primary channel. The second management frame includes a second NPCA mode, which is information about whether the receiving STA performs channel access for the first non-primary channel.
