Abstract: Systems and methods for using a communication system in a spectrum are provided. For example, a random access or RACH procedure may be performed where the random access or RACH procedure may be configured to reduce secondary interference and/or to be used in a pixel-based environment. The random access or RACH procedure may include selecting a RACH preamble; sending a RACH preamble and/or format information; determining a transmission power of the RACH preamble and/or the format information; determining a random access radio network temporary identifier (RA-RNTI) and preamble ID associated with the RACH preamble; and/or selecting a physical RACH (PRACH).

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: A method and apparatus are described for synchronizing mobile station (i.e., wireless transmit/receive unit (WTRU)) media flows during a collaboration session. Inter-WTRU transfer request messages, flow addition request messages and session update request messages may be exchanged between a plurality of WTRUs and a session continuity control application server (SCC-AS). Each of the messages may include a session description protocol (SDP) attribute line containing time synchronization information (e.g., a presentation time offset (PTO) information element (IE), a media flow group identity (ID) and a synchronization tolerance IE). The SCC-AS may update the time synchronization information and include the updated information in messages it sends to the WTRUs, which may re-synchronize their respective media flows based on the updated time synchronization information.

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: Methods and apparatuses for reducing application instantiation delay and downtime are described herein. A method may comprise relocating an application function from a source Edge Data Network (EDN) component to a target EDN component. The method may comprise receiving an indication, and/or determining, based on at least one of a user mobility, resource optimization requirement, key performance indicator (KPI), or a failed relocation attempt, to relocate the application function. The method may further comprise performing a Protocol Data Unit (PDU) session establishment procedure toward the target EDN component. The method may further comprise determining, based on one or more received parameters for edge usage and capabilities, to relocate the application function. The method may further comprise sending, to a European Telecommunications Standards Institute (ETSI) Multi-access Edge Computing (MEC) orchestrator, an indication that the application function will be relocated. The application function may be a User Plane Function (UPF).

Abstract: Embodiments include methods, systems, and apparatuses for content delivery using shared caching, and more specifically, a browser cache extension (BCE) between a local browser cache and a remote cache located on an edge server. In an embodiment, a remote BCE function on the edge server may create a shared cache folder containing a remote cache and an remote cache index file. A local BCE function in the local browser may be able to access the shared cache folder via a network file system (NFS) protocol. The local BCE function may merge the remote index file with a local index file from the local browser and retrieve the remote cache at the local browser.
