摘要： Methods, devices, and systems related to serving gateway extensions for inter-system mobility in integrated small Cell and WiFi networks. An SGW may be extended into a common intermediate gateway for both LTE and WiFi access. A GTP-based “SI a” interface between a TWAN and an SGW is introduced. The STa interface between TWAN and 3 GPP AAA server/proxy is extended to enable selection of an SGW for establishment of the disclosed S1a interface. The extended SGW and protocols may be used to optimize inter-system mobility between LTE small cells and trusted WiFi. SGW and PDN Gateway (PGW) functionality is disclosed to support GTP-based IP flow mobility via multi-access (LTE and WiFi) connectivity to the same packet data network (PDN). Non-access stratum (NAS), EAP, and GTP-C protocols may also be extended to include a “multi-connection” indication in addition to existing “handover” indication.

摘要： A link management service may dynamically configure one or more link-enabling attributes based on a link profile. There may be multiple types of architectures that support the link management service, such as an independent link management and integrated link management.

摘要： New radio channel designs incorporate a synchronization signal burst series frame structure, with higher layer channels mapped to physical channels transmitted during a synchronization signal, allowing user equipment to select beams during which to listen for paging information. A physical common control channel configuration information element may be used to signal the paging configuration as part of the System Information. Paging may occur with or without user equipment assistance.

摘要： A Policy and Charging Enforcement Function (PCEF) can be aware of whether a UE connects through a cellular or WIFI connection through a gateway. Management messages can be modified to allow the PCEF volume based online charging functionality to remain in the core network (i.e. in the P-GW/PCEF). Session management messaging between the ISWN (ISW-GW) and the core network (P-GW/PCEF) may be modified so that the core network may be notified when the ISWN moves a bearer, or flow, from one RAT to another. Alternately, PCEF volume based online charging functionality can be added to the ISWN. The PCEF of the ISWN can be tasked with performing volume based online charging while the UE is in the ISWN.

摘要： Disclosed herein are a variety of devices, methods, and systems for combined proximity services and Internet of Things (IoT) services registration or de-registration. An exemplary method includes one or more of receiving a device initiated IoT service registration request, wherein proximity information relating to the device is contained within the received IoT service registration request; receiving a device initiated proximity service registration request, wherein IoT service information relating to the device is contained within the received IoT service registration request; sending, from an IoT server, a proximity service registration message; and sending, from a proximity manager, an IoT service registration request.

摘要： Multiple mobility sets are maintained for nodes of radio networks. The sets comprise information such as: transmit and receive point identities; cell identities; beam identities; frequency channels; channel bandwidth; and black lists. The sets may be defined at different levels, such as network and physical (PHY) level. A network mobility set, e.g., a new-radio (NR) mobility set may, be determined by the gNB, the cell, the UE, or another device. Multiple radio access network nodes and UEs may exchange mobility set information to achieve a distributed mobility solution. A UE may monitor its orientation relative to a TRP, e.g., via use of an onboard MEMS gyroscope, and alter its beamforming parameters in response to changes in orientation and/or changes in TRP connection strength. Cell selection and reselection for beam based networks may use Single Frequency Network (SFN) broadcast of initial access signals without beam sweeping.

摘要： Hybrid automatic repeat request (HARQ) processes, indicators, and similar methods may be used improve new radio performance in a number of ways. For example HARQ processes may be retransmitted, even before a response is expected, a number of times. Separate acknowledgement may be provided for various code blocks within a single transport block. Multi-bit ACK/NACK signaling may be used to efficiently express the status of individual code blocks or groups of code blocks within a transmission block. Grantless transmissions may be acknowledged implicitly, e.g., via responses comprising downlink control information or sent via a physical hybrid automatic repeat request indicator channel.

摘要： Management of context and power control information enables different power control schemes for point-to-point or point-to-multipoint based on proximity services or applications. Context information may be defined as situation data about a service or application that is used to help define a power control scheme to be implemented. Power control information may be defined as control or status data for power control, which can be used for reporting or controlling the transmitting power of a peer in a P2P network. Context and power control information may be managed across multiple layers such as the application layer, service layer, media access control layer, or physical layer. Context and power control information is updated and exchanged between or among peers for context-related power control in proximity services.

摘要： System information can include a basic set of system information and additional system information. A UE can receive the basic set of system information and then later request or receive the additional system information. Messages can use tags which can be used to look up locally stored system information. If a tag does not correspond to any locally stored system information, the system information and an associated tag can then be requested. Messages can be indicative of a cluster identity associated with cells. When the UE goes into a new cell, the cluster identity can be checked to see if system information from a prior call can be reused.

摘要： Current approaches to transmitting uplink data in a network often require resources to be granted. In an example, a node or apparatus may configure a plurality of devices to operate in a grant-less mode in accordance with a respective grant-less access allocation. Grant-less operations may be managed, for example, to meet the reliability and latency requirements and battery life requirements for different types of devices. For example, the state transition between grant-less and grant based may be managed.
