Abstract:
Devices, methods, communication nodes, base stations, storage media, and other embodiments are provided for managing associations in a communication network. In one example embodiment, a New Radio (NR) node is configured for NR user-plane protocol communications between a master node (MN) and a secondary node (SN). The NR node is configured to generate a downlink (DL) user data message with downlink user data, initiate transmission of the DL user data message to a second node, and process a DL data delivery status message from the second node in response to the DL user data message. In various embodiments, polling and SCG split-bearer configurations are supported by such messaging. In some embodiments, packet data convergence protocol (PDCP) serial numbers are communicated for transmission and retransmission management. In some embodiments, DL configurations initiated by an SN are enabled, as well as UL configurations initiated by either an MN or an SN.
Abstract:
Methods, systems, and storage media for reserving radio resources for providing accurate and reliable vehicle-to-everything (V2X) positioning are described. The V2X positioning mechanisms may allow vehicle user equipment (vUEs) to determine a relative position, which may include measuring a distance between a vUE and another proximate device using Time-of-Flight technology. The V2X positioning mechanisms may include bidirectional distance measurements, unidirectional distance measurements, non-synchronized downlink only positioning, and positioning enhancements using radio measurements. Other embodiments may be described and/or claimed.
Abstract:
Mapping information of a bearer or quality of service can be communicated from a Wireless Local Area Network Termination (WT) to the enhanced Node B (eNB), which then uses radio resource control (RRC) signaling to communicate the mapping to the user equipment (UE). For example, three options can be used to communicate mapping information: (1) Operations and Management (OAM), (2) Semi-static Xw-AP signaling (e.g., WT Configuration Update or Xw Setup procedures) or (3) Dynamic Xw-AP procedures (e.g., WT Addition Request procedure). In some embodiments, the mapping can be signaled by (1) bearer to wireless local area networks (WLAN) access category (AC) mapping or (2) long term evolution (LTE) quality of service class identifier (QCI) to WLAN AC mapping.
Abstract:
Briefly, in accordance with one or more embodiments, an apparatus of a source evolved Node B (eNB) to perform a handover of a user equipment (UE) to a target eNB comprises one or more baseband processors to generate a handover request message for the target eNB, wherein the handover request message indicates a RACH-less handover is to be used, and to process a handover request acknowledge message from the target eNB, and a memory to store the handover request acknowledge message. The one or more baseband processors determine if a RACH-less handover should be applied based at least in part on the handover acknowledge message, and the handover request acknowledge message indicates that the target eNB is capable of a RACH-less handover via a periodic uplink grant in mobility control information in the handover request acknowledge message.
Abstract:
Long Term Evolution (LTE)/Wireless Local Area Network (WLAN) Aggregation (LWA) techniques for tri-band Wi-Fi equipment are disclosed herein. An apparatus of an evolved NodeB (eNB) can include processing circuitry configured to decode a WLAN Band IE in an Xw-Application Protocol message from an AP via a WLAN termination (WT). The WLAN Band IE indicates combinations of communication bands (2.4 GHz, 5 GHz, and 60 GHz) supported by the AP. An RRC message from a UE is decoded. The RRC message indicating combinations of the one or more communication bands supported by the UE. A reconfiguration message is encoded for transmission to the UE when the AP and the UE support at least a common one of the communication bands. The reconfiguration message configures the UE to associate with the AP and to receive eNB data concurrently from the eNB and from the AP using LWA.
Abstract:
Embodiments of the present disclosure relate to support of a 60 gigahertz (GHz) band related to enhanced long term evolution (LTE) - wireless local area network (WLAN) Aggregation (eLWA). Some embodiments may relate to mechanisms by which a user equipment (UE) can signal support of the 60 GHz band. Other embodiments may relate to mechanisms by which an evolved NodeB (eNB) can signal information to the UE related to the 60 GHz band. Other embodiments may be described and/or claimed.
Abstract:
A change of a wireless local area network termination (WT) can be used to avoid service disruption. By using a WT change instead of a release and addition, service interruption visible to the user can be avoided. The WT change can be performed using a (1) break before make method and/or a (2) make before break method. In addition, a WT change can also be performed (3) during handover. For example, in a (1) break before make scenario, an eNB can release a source WT before the UE associates with the target WT. In another example, in a (2) make before break scenario, an eNB can release a source WT after the UE associates with the target WT. In yet another example, in a (3) handover scenario, a UE transitions from a source WT to a target WT while transitioning from a source eNB to a target eNB.
Abstract:
A mobile communication device may include a first modem configured to transmit and receive radio signals on a cellular wide area radio access, a second modem configured to transmit and receive radio signals on a short range radio access, and a connection management circuit configured to monitor radio access transfers of one or more packet data network connection to generate a transfer history database, determine from the transfer history database if excessive previous transfers of the one or more packet data network connections occur between the cellular wide area radio access and the short range radio access, identify an available transfer of a target packet data network connection of the one or more packet data network connections between the first modem and the second modem, and selectively block the available transfer between the first modem and the second modem based on if excessive previous transfers of the one or more packet data network connections occur between the first modem and the second modem.

Some demonstrative embodiments include devices, systems and/or methods of establishing a connection between a cellular node and a core network. For example, a first Evolved Node B (eNB) may include a cellular transceiver to communicate with a User Equipment (UE); an X2 interface to communicate with at least one second eNB; and a controller to send to the second eNB a first message including a core network node discovery request, to receive from the second eNB a second message including a core network node identifier, and to establish an S1 connection between the first eNB and a core network using the core network node identifier.
Abstract:
Embodiments of the present disclosure are directed towards devices and methods for identifying preferred access networks based at least in part on access network information including access network assistance information, steering policies, or access commands. In some embodiments, conflicts between access network information and access network discovery and selection function (ANDSF) policies may be rectified in identifying a preferred access network.
