    Abstract: UE-assisted management of advanced radio link feature in a wireless communication network may include a network entity determining that a mobile entity is capable of communicating with one or more base stations using a set of radio link configurations, receiving a request from the mobile entity to restrict use of at least one of the radio link configurations, and restricting use of the at least one of the radio link configurations for communicating with the mobile entity, based on the request. The request may indicate a reason for the restriction, and the network entity may determine whether to restrict based on the reason. Once a radio link configuration is restricted, it may similarly be unrestricted based on a subsequent UE request, or based on expiration of a time period.

    Abstract: Techniques are described for wireless communication. A first method may include transmitting a reference signal from an access point over a shared spectrum to a user equipment (UE), and receiving a measurement of the reference signal from the UE. A second method may include receiving at a UE over a shared spectrum a reference signal from an access point, and transmitting a measurement of the reference signal to the access point. In each of the first and second methods, the measurement may indicate interference with the shared spectrum from outside of a clear channel assessment (CCA) range of the access point. A third method may include receiving a plurality of reference signal measurements, where each reference signal measurement corresponds to one of a plurality of access points and indicates interference with a shared spectrum from outside of a CCA range of the corresponding access point, and performing channel selection for the plurality of access points based at least in part on the received reference signal measurements.

    Abstract: Techniques are described for wireless communication. One method includes determining that a cell operates in a shared access radio frequency spectrum, and transmitting signaling information to a mobile device indicating that the cell is prohibited from serving as a primary serving cell based at least in part on the determination that the cell operates in the shared access radio frequency spectrum. Another method includes receiving signaling information at a mobile device from a base station indicating that a cell operating in a shared access radio frequency spectrum is prohibited from serving as a primary serving cell, and identifying the cell as prohibited from serving as a primary serving cell based at least in part on the received signaling information. Another method includes identifying, by a mobile device, a cell operating in a shared access radio frequency spectrum as a secondary serving cell based at least in part on information stored on the mobile device.

    Abstract: The subject technology provides for performing clear channel assessment (CCA) in LTE-U. Transmissions may be monitored in a resource reserved for CCA. An energy of the transmissions is detected over a shorter duration than an assigned slot in the resource reserved for CCA. A beacon may be transmitted in a slot assigned to a wireless entity for CCA in response to detecting a clear channel based on the monitoring. In another aspect, a beacon transmission for CCA and a timing for the monitoring are adapted in response to detecting the transmissions for a consecutive number of CCA periods. Further, the subject technology provides for adjusting to a maximum power for transmission of a beacon in a slot assigned to a mobile station for CCA in response to detecting a clear channel based on the monitoring.
