Abstract: A router encapsulates a payload of a packet in a generic routing encapsulation (GRE) header that defines a connectionless GRE tunnel. The router also encapsulates the payload and the GRE header in one or more reliable transport headers associated with a connection formed using a reliable transport layer. The router conveys the packet via the connectionless GRE tunnel over the reliable transport layer. In some cases, the GRE header is a network virtualization using GRE (NVGRE) header that allows multiple NVGRE overlays to be multiplexed onto a single IP underlay tunnel. The reliable transport layer can be implemented as Transmission Control Protocol (TCP) layer, a QUIC protocol, a Stream Control Transmission Protocol (SCTP) or a QUIC protocol to establish a set of multiplexed sub-connections or streams over a single connection between two endpoints of the tunnel, or a transport layer security (TLS) cryptographic protocol.

Abstract: A wireless device transmits, via a first uplink bandwidth part (BWP), a first preamble for a random-access procedure. A determination is made of a second uplink BWP for transmission of a second preamble for the random-access procedure. The determination is based on not receiving, via a first downlink BWP associated with the first uplink BWP, a random-access response corresponding to the first preamble. Based on the determination of the second uplink BWP, the first downlink BWP is switched to a second downlink BWP associated with the second uplink BWP. The second preamble is transmitted via the second uplink BWP.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for a user equipment (UE) of a wireless communication system. The UE includes a processor circuitry, and radio front end circuitry coupled to the processor circuitry. The processor circuitry is configured to determine and indicate, to a core network via a radio access network (RAN), one or more cellular internet of things (CIoT) features that are required by the UE and CIoT network behavior expected from the core network to support the one or more CIoT features that are required by the UE. The processor circuitry is configured to select either an enhanced packet core (EPC) or a 5G core (5GC) to establish a wireless connection with the core network, based on a first set of CIoT features supported by the EPC and a second set of CIoT features supported by the 5GC received from the core network.

Abstract: Techniques and architecture are described that utilize switchport protected flags to provide switchport protected functionality across network devices, e.g., switches, routers, etc., in fabric networks. For example, a first port of a first network device of a fabric network receives a packet from a first host destined for a second host. The second host is onboarded to the fabric network via a second port of a second network device. It is determined (i) if a first protected flag associated with the first port of the first network device is set as true and (ii) if a second protected flag associated with the second host is set as true. Based at least in part on (i) the first protected flag associated with the first port being set as true and (ii) the second protected flag being set as true, the first network device drops the packet.

Abstract: An electronic device may be provided with a phased antenna array on an antenna module. The array may include low band antennas and high band antennas that radiate at frequencies greater than 10 GHz. The module may include antenna layers, transmission line layers, and ground traces that separate the antenna layers from the transmission line layers. The low band antennas and the high band antennas may have radiators patterned onto the antenna layers. The radiators may be fed by transmission lines on the transmission line layers. The antenna layers may have a dielectric permittivity that is greater than the dielectric permittivity of the transmission line layers. This may serve to reduce the lateral footprint of the low band and high band antennas, which allows the antennas to be interleaved along a common linear axis in the phased antenna array, thereby minimizing the lateral footprint of the antenna module.

Abstract: In response to receiving from a source RAN node (2), on a direct interface (101), a message requesting a handover of a radio terminal (1) from a first network to a second network, a target RAN node (3) receives at least one of slice information and flow information from a core network (5), and controls communication of the radio terminal (1) based on at least one of the slice information and the flow information. The slice information relates to a network slice in the second network. The flow information relates to at least one session to be established in the second network, serving as a bearer-less network, in order to transfer at least one packet flow of the radio terminal (1). It is thus possible, for example, to provide an Inter-RAT handover procedure involving transfer of handover signaling messages on a direct inter-base-station interface.

Interrupts associated with the packet with other interrupts associated with other packets are coalesced based on one or more of the last fragment index and the fragment count.
