Apple patents faster switching for secondary wireless connections

Apple describes a method for managing secondary cells in wireless networks by using specific triggering modes. The device receives instructions to activate a secondary connection and send a temporary reference signal to speed up the process.

Why it mattersThis could help reduce the delay when a phone switches between different parts of a cellular network, potentially improving connection stability.

In the filing’s own words

Embodiments of the present disclosure relate to methods, a terminal device, a network device, and computer program products for SCell management in wireless communication. A terminal device receives from a network device configuration information for configuring a triggering mode. The triggering mode is for triggering activation of a secondary cell of the terminal device and a transmission of a temporary reference signal in the secondary cell. Based on the configured triggering mode, the terminal device receives first triggering information on the activation of the secondary cell and second triggering information on the transmission of the temporary reference signal for performing the activation of the secondary cell. In this way, it is possible to reduce the latency of activation/de-activation procedure for SCG and secondary cells.
