    Abstract: The functions of user equipment (UE), radio access network (RAN) devices, and core network (CN) devices in circumstances where a UE is expected to experience discontinuous coverage are described herein. A UE may send a CN a non-access stratum (NAS) message including a release request indicating that a UE is leaving coverage and assistance information. The CN may interrupt paging of the UE and resume the paging according to the assistance information. A UE may enter a low power usage mode upon leaving coverage, and may use one or more timers to determine when to check for coverage and send a mobility update message corresponding to the low power usage mode. A base station may receive, from a UE, a radio resource control (RRC) message comprising a release request and assistance information, send an RRC release message to the UE in response, and forward the assistance information to the CN.

    Abstract: Techniques are disclosed for the spectrum sharing without network sharing. One example includes a method implemented for spectrum sharing without network sharing. A first network node can transmit, via a horizontal user plane interface, a first message to a second network node. The message can include a request for shared spectrum. The first network node can be configured to transmit a first network identifier associated with a first operator. The second network node can be configured to transmit a second network identifier associated with a second operator. The first network node can receive, via the horizontal user plane interface, a second message from the second network node. The second message can coordinate shared spectrum access between the first network node and the second network node. The first network node can access the shared spectrum, based on the response.
