Abstract
Embodiments of the disclosure relate to assigning unique temporal delays to signal paths assigned to remote units in a wireless distribution system (WDS). In one aspect, each remote unit in a WDS is assigned a unique identification temporal delay. Each uplink and/or downlink communications signal is delayed for a respective assigned unique identification temporal delay. By examining a respective assigned unique identification temporal delay of an uplink and/or downlink communications signal, it is possible to uniquely identify the remote unit from which the uplink and/or downlink communications signal is communicated. In another aspect, the unique identification temporal delays assigned to any pair of adjacent remote units differ by more than one predefined timing advance (TA) step. By separating the unique identification temporal delays between adjacent remote units by more than one predefined TA step, it is possible to improve reliability in uniquely identifying a plurality of remote units.
