Abstract: A method and apparatus for operating supplementary cells in licensed exempt (LE) spectrum. An aggregating cell operating in a frequency division duplex (FDD) licensed spectrum is aggregated with a LE supplementary cell operating in a time sharing mode for uplink (UL) and downlink (DL) operations. The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.

Abstract: A method of Inter-User Equipment (UE) Transfer (IUT) for use in an Internet Protocol (IP) Multimedia Subsystem (IMS) capable wireless transmit/receive unit (WTRU), the method comprising: receiving a registration request from a non-IMS capable WTRU; translating the registration request to an IMS based message; transmitting the translated IMS based message to a Service Centralization and Continuity Application Server (SCC AS), transmitting an IUT transfer command, transmitting an IUT process message; receiving an IUT process-accept message; and establishing an IMS session between the non-IMS capable WTRU and the remote party.

Abstract: Methods and systems may be used by a mobile-content distribution network (CDN) service to track individual user requests based on a correlation of a network level identifier to an application level identifier. The users may also be tracked using a mapping of the network level and application level identifiers to an internal identity. Further, the mobile-CDN service may build a cell profile using content requests from a set of active users across similar locations. Also, the mobile-CDN service may build a cell profile using content requests from user groups that have at least one member as an active user of the cell. Using a cell profile, the mobile-CDN may generate a prefetching content list for managed caching in the cell by localizing the content popularities and viewing patterns. The methods and systems may be applied in a small cell network (SCN).

Abstract: Systems, methods, and apparatus may be used to provide assistance for connection procedures in a hierarchical network where macro cells may be operating in licensed spectrum while small cells may be operating in dynamic and shared spectrums, such as TVWS. This may be done, for example, to allow an LTE system performing carrier aggregation (CA) to reconfigure itself to change from a supplementary cell (SuppCell) in one dynamic and shared spectrum channel to a SuppCell in another dynamic and shared spectrum channel.

Abstract: Techniques for inter-user equipment (UE) transfer (IUT) are disclosed. An application server may receive an IUT request for transfer of a media session toward at least one initial UE such that the media session is to be played by at least two target UEs. The server may determine eligibility for IUT with group synchronization based on the request. The server may send a message to the initial UE that IUT with group synchronization is not allowed on a condition that IUT with group synchronization is not allowed. Further, the server may trigger inter-destination media synchronization (IDMS) for group synchronization of media sessions among the UEs on a condition that IUT with group synchronization is allowed. The media sessions may include a first media session and second media session. The media stream may be played by at least two UEs that are geographically separated after the transfer.

Abstract: A base station device may include a processor and memory. The base station device may be configured to receive a registration request from a WTRU. The registration request may include an indication that the WTRU is requesting access to a private network. The base station device may send the registration request to a network node. The base station device may receive an identifier of the WTRU from a network node. The base station device may determine whether the WTRU is authorized to access the private network based on the received identifier of the WTRU and a list of allowed device identifiers for the private network. The base station device may send authorization information and an indication that the WTRU has been authorized to access the private network to the network node. The base station device may forward a registration accept message to the WTRU.

The function may be referred to as LFE, for example, if used in EMEC. The function may be referred to as LFC, for example, if used in CMEC. In examples, one or more interfaces may be used between LF entities in EMEC and CMEC, for example, to discover applications. In examples, the interfaces may be referred to as Mpp-lfe and Mpp-cmec. Systems, methods, and/or instrumentalities for one or more of the following may be described herein: EMEC initiated discovery of one or more applications in CMEC, CMEC initiated registration with EMEC to announce availability of application(s), or CMEC initiated discovery of other CMEC application(s).
