DISTRIBUTED ANTENNA SYSTEM WITH UPLINK BANDWIDTH FOR SIGNAL ANALYSIS

摘要

One embodiment is directed towards a distributed antenna system (DAS). The DAS includes a host unit a plurality of remote units communicatively coupled to the host unit. The plurality of remote units are configured to implement a common arrangement of resource blocks for uplink transport signals. The host unit is configured to instruct a subset of the plurality of remote units to send a digital sample stream over a monitor path of their respective uplink transport signals. One or more simulcast modules are configured to sum the monitor paths from the respective uplink transport signals to generate a summed digital sample stream, the one or more simulcast modules configured to send the summed digital sample stream to the host unit. The host unit is configured to provide a signal based on the summed digital sample stream to one or more signal analysis modules

1. A distributed antenna system comprising:
a host unit; a plurality of remote units communicatively coupled to the host unit; a plurality of communication links to communicatively coupling the host unit to the plurality of remote units, wherein the plurality of remote units are configured to implement a common arrangement of resource blocks for uplink transport signals on associated ones of the plurality of communication links; one or more simulcast modules configured to implement simulcasting of signals; wherein the host unit is configured to instruct a subset of the plurality of remote units to send a digital sample stream over a monitor path of their respective uplink transport signals, wherein the instruction from the host unit indicates to which antenna of multiple antennas at each respective remote unit in the subset of remote units the digital sample stream is to correspond; wherein the one or more simulcast modules are configured to sum the monitor paths from the respective uplink transport signals to generate a summed digital sample stream, the one or more simulcast modules configured to send the summed digital sample stream to the host unit; and wherein the host unit is configured to provide a signal based on the summed digital sample stream to one or more signal analysis modules.
