Abstract: The disclosure provides a method for spatial reuse of time resources. A method performed by a UWB device includes receiving, from a first initiator anchor, a first poll message to initiate a DL-TDoA for a first cluster to which the first initiator anchor belongs, the first initiator anchor providing a time reference for an inter-cluster synchronization; performing the inter-cluster synchronization for using a common ranging block, based on the first poll message; and transmitting a second poll message to initiate a DL-TDoA for a second cluster to which the UWB device belongs. The first poll message is transmitted in a first ranging round in the common ranging block, and the first poll message is transmitted in a second ranging round in the common ranging block.
