Abstract: A distributed antenna system (DAS) includes host that receives downstream signals corresponding to radio frequency (RF) channel and remote antenna units (RAUs) communicatively coupled to host. Host communicates downstream transport signal derived from downstream signals received at host to RAUs. Each RAU uses downstream transport signal to generate downstream RF signal for radiation from antenna associated with RAU. Downstream RF signal comprises a subset of plurality of downstream frequency bands. Each RAU receives upstream RF signal including respective RF channel. Each RAU communicates upstream transport signal derived from upstream RF signal to host. Host uses upstream transport signal to generate upstream signal including at least one upstream frequency band. Host analyzes attribute of downstream and upstream transport signals associated with RAUs, correlates analyzed attribute for each RAU with profile, and determines current capacity usage of RAUs based on correlation. Host dynamically allocates capacity amongst RAUs based on current capacity usage.

Abstract: One embodiment is directed to a distributed antenna system comprising a host unit and at least one remote antenna unit that is communicatively coupled to the host unit. The host unit is configured to communicate a downstream transport signal from the host unit to the remote antenna unit. The remote antenna unit to which the downstream transport signal is communicated uses the downstream transport signal to generate a downstream radio frequency signal for radiation from an antenna associated with the remote antenna unit. The remote antenna unit is configured to communicate an upstream transport signal from the remote antenna unit to the host unit, wherein the upstream transport signal is generated from a received upstream radio frequency signal received at the remote antenna unit. The remote antenna unit is configured to perform self-interference suppression processing in an upstream signal path using, as an input thereto, a feedback signal derived from the downstream radio frequency signal radiated from the antenna. Other embodiments are disclosed.
