Networks that support 5G communication may support different numerologies across and even within a symbol, slot, or subframe. Sequences, such as reference signals or data scrambled with a scrambling code, may be transmitted on resources with such mixed numerologies. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment. The UE may be configured to receive an indication of assigned resources for communicating with a base station. The UE may also be configured to determine a numerology associated with the assigned resources, and to determine one or more indices based on the numerology. The UE may also generate a sequence based on the one or more indices and communicate with the base station based on the sequence.

The present disclosure provides a modem and a communication method. The modem includes a processor. The processor scans a first network channel of a plurality of network channels provided by the modem. The processor enters an idle scan time period and performs a packet forwarding operation during the idle scan period upon completion of scanning the first network channel. The processor scans a second network channel of the plurality of the network channels after the scanning idle period.

A network arrangement is provided for a charging park for providing IP services to the charging park. The charging park has a plurality of components. The network arrangement comprises a core network, a backend server and a central gateway that is coupled to the core network and to the backend server. The central gateway provides an interface for one or more communication nodes of the core network. The components of the charging park are connected communicatively to one another and to the central gateway via the core network. Each component of the charging park has an associated communication node of the core network, and the components of the charging park can interchange data with the backend server via the central gateway via their respective associated communication nodes and the interfaces associated with the communication nodes. Further, the invention relates to a method for addressing components of the charging park.

Through the identification of different packet-types, packets can be handled based on an assigned packet handling identifier. This identifier can, for example, enable forwarding of latency-sensitive packets without delay and allow error-sensitive packets to be stored for possible retransmission. In another embodiment, and optionally in conjunction with retransmission protocols including a packet handling identifier, a memory used for retransmission of packets can be shared with other transceiver functionality such as, coding, decoding, interleaving, deinterleaving, error correction, and the like.

A technique for managing real-time communications includes generating, during a communication session between at least a first computing device and a second computing device over a computer network, multiple audio factors of the communication session, each of the audio factors being susceptible to degradation in a way that affects audio quality of the communication session. The technique further includes combining the audio factors to produce an overall measure of audio quality and taking remedial action to improve the overall measure of audio quality by adjusting a setting on the first computing device.

A logical router includes disaggregated network elements that function as a single router and that are not coupled to a common backplane. The logical router includes spine elements and leaf elements implementing a network fabric with front panel ports being defined by leaf elements. Control plane elements program the spine units and leaf to function a logical router. The control plane may define operating system interfaces mapped to front panel ports of the leaf elements and referenced by tags associated with packets traversing the logical router. Redundancy and checkpoints may be implemented for a route database implemented by the control plane elements. The logical router may include a standalone fabric and may implement label tables that are used to label packets according to egress port and path through the fabric.
