摘要： A method for managing a network function (NF) entity in a network slice instance. The method comprises actions of accessing descriptor entities (DE) that each DE describes deployment and operational behaviour of the NF entity, including at least one DE that relates to the network slice instance and issuing a request to update a configuration of the NF entity. The DE lies in the management plane. The update request is in accordance with policy in the accessed DEs. The method may also comprise the action of obtaining performance feedback information from the NF entity regarding performance of the NF entity.

摘要： A method is provided for applying HOM to a PDCCH to transmit control information from an access node to a UE. The method comprises: selecting a DCI format for a HOM PDCCH; determining a DCI block of the HOM PDCCH according to the selected DCI format; generating a sequence of coded bits to be transmitted from the DCI block; multiplexing the sequence of coded bits of the HOM PDCCH with coded bits of other PDCCHs to form a sequence of multiplexed bits; scrambling the sequence of multiplexed bits to form a sequence of scrambled bits; modulating the scrambled bits to form a sequence of modulation symbols; and transmitting the sequence of modulation symbols, where a PDCCH is transmitted on an aggregation of one or more CCEs.

摘要： The signals from adjacent transmitters reinforce one another. As a result of this over-the-air combining, signal quality is improved in the network and especially at or near cell boundaries. The present invention provides a graduated single frequency network (GSFN) wherein transmitters in cells throughout a geographic area cooperate to broadcast data to user terminals throughout the geographic area, and adjacent transmitters transmit signals that substantially reinforce one another. When transmitting the data, transmitters in certain adjacent cells throughout the geographic area may employ slightly different transmit parameters to provide slightly different transmission signals. The transmission signals used to transmit the data may be varied in a graduated fashion throughout the geographic area, wherein even when there is a difference in the transmission signals of transmitters in adjacent cells, the transmission signals reinforce one another despite being different.

摘要： A system and method for adaptively managing frame size in a wireless multihop network is disclosed. In one embodiment, a packet is transmitted from a source to a destination. A acknowledgement packet is received and a successful acknowledgement packet counter is incremented if the acknowledgement packet arrives prior to a time-out of a timer. A frame size is increased if the successful acknowledgement packet counter reaches a specified value. If the acknowledgement packet arrives after the time-out of the timer, the successful acknowledgement packet counter is reset and the frame size is decreased. These procedures can be repeated until the frame size is greater than or equal to a maximum frame size or less than or equal to a minimum frame size.

摘要： A cellular communications system uses FCS (fast cell switching) for forward communications links, for communicating data from respective cells or sectors to a mobile terminal, in response to FCS requests by the terminal on a reverse communications link. An FCS rate, or rate of said requests, is varied in dependence upon a C/I reliability criterion, which represents a reliability with which C/I is determined and predicted by the mobile terminal, for example being either of two selected rates depending upon a comparison of the criterion with a threshold. The criterion can be, for example, a determined speed of the mobile terminal, or an averaged probability that a C/I prediction error is less than a predetermined amount.

摘要： A method and system for responding to demand-based charging in a communication network, such as a 5G wireless communication network. Service providers and/or infrastructure providers adjust network usage pricing dynamically based on demand. Customers such as Virtual Network operators respond to pricing adjustments by adjusting their network usage, service requirements, and/or by re-negotiating the pricing structure. Network usage can be adjusted by controlling network traffic generated in response to activity of end-user devices of the Virtual Network.

摘要： Aspects of the disclosure provide systems and methods for establishing one or more Distributed Gateways located close to a location of a UE to facilitate faster packet delivery to said UE during transitions. Such transitions can include the UE transitioning its state, for example from being idle to connected to the network, but also includes operations in which the serving AP(s) for the UE changes. The method includes establishing at least two virtual network function (VNF) components (VFNCs) of a distributed gateway (D-GW), each VNFC associated with an access point (AP). Each VNFC buffers packets directed to the wireless device. The method further includes selecting at least one AP for serving the wireless device, and forwarding the buffered packets from the VNFC associated with the selected APs to the selected APs for forwarding to the wireless device. Packets buffered at the VNFCs of non-selected APs are discarded.
