Document Type and Number:
WIPO Patent Application WO/2023/004702
Kind Code:
A1
Abstract:
The present application provides a transmission rate determination method and a communication apparatus, which relate to the technical field of chips, and which can improve link stability and reduce unnecessary link disconnection. The method comprises: a proximity coupling device (PCD) sends an activation frame to a proximity integrated circuit card (PICC); the activation frame at least indicates a first transmission rate for transmitting a first information frame and a second transmission rate for transmitting a target frame; the first information frame is used to transmit application information; and the target frame comprises at least one among the following: a second information frame and a third information frame, wherein the second information frame is used to transmit receive ready information, and the third information frame is used to transmit control information; the PCD receives an acknowledgement frame from the PICC, wherein the acknowledgement frame indicates that the PICC has received the activation frame; and thereafter, the PCD transmits the first information frame to the PICC by using the first transmission rate, and transmits the target frame to the PICC by using the second transmission rate.
