Embodiments are directed to compensating for increased signal propagation delay in a distributed antenna system. The distributed antenna system is configured to determine an apparent delay based on a delay variable. A distributed unit or other radio access network node uses the apparent delay instead of the actual delay to determine other delays between signal paths between the radio access network node and the distributed antenna system. Because the radio access network node overcalculates the delays between the signal paths that couple the radio access network node to the distributed antenna system, the distributed antenna system can underreport delays from the distributed antenna system that are within a maximum delay threshold.
A method for compensating excessive time delay due to signal propagation in a distributed antenna system, wherein the distributed antenna system comprises at least one master unit coupled to a plurality of radio units, wherein each radio unit of the plurality of radio units is coupled to at least one antenna, wherein the at least one master unit is coupled to at least one radio access network (RAN) node, the method comprising:
The distributed antenna system of claim 10, wherein the at least one RAN node comprises a distributed unit (DU).
The distributed antenna system of claim 10, wherein the at least one apparent signal path time delay includes an apparent downlink signal path time delay of the distributed antenna system and/or an apparent uplink signal path time delay of the distributed antenna system.
The distributed antenna system of claim 10, wherein the at least one signal path time delay corresponds to a difference in time from when the signal is received at an input/output (I/O) port of the at least one master unit and when the signal is received at an I/O port of a radio unit of the plurality of radio units.
The distributed antenna system of claim 10, wherein the distributed antenna system comprises at least one intermediate combining node (ICN) coupled between the at least one master unit and at least one radio unit of the plurality of radio units, wherein the at least one signal path time delay corresponds to a difference in time from when the signal is received at an input/output (I/O) port of the ICN and at least one of:
The distributed antenna system of claim 10, wherein the apparent loopback processing delay corresponds to a minimum time period associated with the at least one master unit in processing the query message.
The distributed antenna system of claim 10, wherein the at least one signal path time delay is greater than a threshold value indicative of a maximum tolerance corresponding to the respective at least one signal path time delay, wherein the at least one apparent signal path time delay is less than the threshold value.
