  • Publication number: 20240137985
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication transmitter may monitor a clear channel assessment (CCA) for a primary bandwidth associated with the transmitter. The wireless communication transmitter may determine whether an interferer is located within the primary bandwidth based at least in part on tracking packet drops, within the primary bandwidth, that are based at least in part on the CCA. The wireless communication transmitter may monitor one or more additional CCAs for one or more secondary bandwidths associated with the transmitter. The wireless communication transmitter may determine whether an interferer is located within at least one bandwidth, of the one or more secondary bandwidths, based at least in part on tracking packet transmissions, within the one or more secondary bandwidths, that are based at least in part on the one or more additional CCAs. Numerous other aspects are described.

  • Publication number: 20210409977
    Abstract: One embodiment is directed to an open radio access network to provide wireless coverage for a plurality of cells at a site and that comprises a virtualized headend comprising one or more base-station nodes and a plurality of unified remote units deployed at the site. Each of the unified remote units is able to support multiple functional splits, multiple wireless interface protocols, multiple generations of radio access technology, and multiple frequency bands. The unified remote units and functional split used to serve each cell can be changed (for example, on-the-fly as a part of an automatic or manual adaptation process that is a function of one or more monitored performance attributes of the open radio access network such as network bandwidth, network latency, processing load, or processing performance). The unified remote units can be implemented in a modular manner with a backplane to which different radio modules can be coupled.
