Abstract: The present disclosure presents a method and an apparatus for improving performance of a user equipment (UE) operating in unlicensed spectrum. For example, the disclosure presents a method for receiving, at the UE, a secondary component carrier (SCC) update from a small cell. The example method further includes tuning the UE to a second SCC in response to receiving the update. The update is received at the UE when the small cell operating on a first radio access technology (RAT) determines that a channel associated with a first SCC of the small cell is also in use by another entity operating on a second RAT. As such, improved performance of a user equipment (UE) operating in an unlicensed spectrum may be achieved.

Abstract: A base station includes a base unit and a plurality of remote antenna units (RAUs). Each of the RAUs includes a physical layer circuit (PHY). The PHYs are configured to each use the same physical layer identifier, but each PHY includes its own hardware for supporting users in the coverage area of that PHY. The base unit controls resource allocation for the RAUs to increase the capacity of the base station and/or reduce interference between PHYs.

Abstract: Techniques for managing contention on a shared communication medium are disclosed. Various techniques are provided to facilitate aspects such as reference signaling, downlink medium access, uplink medium access, resource reuse, channel structures, acknowledgment schemes, fairness, acquisition, random access, paging, mobility, inter-operator mitigation, and so on for a frame structure implemented on the shared communication medium.

Abstract: Aspects for reducing interference between networks are provided. A signal transmitted by a first network over a communications medium using an unlicensed frequency spectrum is decoded to determine one or more parameters of a packet in the signal. A level of utilization of the communications medium by the first network can be estimated based at least in part on a signal strength of the signal and the one or more parameters. A time for communicating in a second network over the communications medium using the unlicensed frequency spectrum can be adjusted based at least in part on the level of utilization of the communications medium by the first network.
