Assignee: NXP B.V.
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 0:
1. An ultra-wideband communication node, comprising:
processing circuitry coupled to ultra-wideband (“UWB”) circuitry configured to communicate with an external UWB anchor device over a first communication channel;
wherein the processing circuitry is configured to transmit, using the ultra-wideband circuitry, one or more ultra-wideband frames to the external device via the first communication channel;
wherein the processing circuitry is further configured to:
determine scrambled timestamp sequences for said ultra-wideband frames;
determine designated time slots of said ultra-wideband frames within which said scrambled timestamp sequences are to be received by said external device;
transmit the scrambled timestamp sequences to the external device in the designated time slots of said ultra-wideband frames using the ultra-wideband circuitry; and
transmitting data that identify the designated time slots of said ultra-wideband frames to the external UWB anchor device.
