    Abstract: Facilitating operation and support of mobile relays based on an integrated access and backhaul concept for advanced networks (e.g., 4G, 5G, 6G, and beyond) is provided. An embodiment relates to a communication network architecture that can comprise a control plane architecture of a relay node device. The control plane architecture can comprise a star-type architecture. Further, the communication network architecture can comprise a user plane architecture of the relay node device. The user plane architecture can be separated from (or independent of) the control plane architecture. Further, the user plane architecture can comprise a multi-hop architecture. The relay node device can be configured to operate according to a fifth generation wireless network communication protocol, or other advanced communication protocols.

    Abstract: The described technology is generally directed towards dynamic resource coordination that supports multi-hop based relaying for integrated access and backhaul (IAB) in New Radio (5G). Described is a technology in which an IAB node and a serving parent node use wireless signaling to dynamically adapt downlink and uplink resources used for access and backhaul links. An IAB node receives scheduling data from a parent node, configures a frame structure comprising mobile termination function subframes and distributed unit component subframes, and communicates data based on the frame structure. The parent node explicitly or implicitly indicates that a portion of the scheduling data is adaptable, e.g., sends a dynamic frame structure coordination message. In response, the IAB node can adapt the frame structure into a modified frame structure and can communicate further data based on the modified frame structure.

    Abstract: The described technology is generally directed to supporting user plane adaptation via mobile relays based on the integrated access and backhaul (IAB) features of 5G New Radio. In various aspects, signaling and procedures are provided for reconfiguring radio bearers of a group of one or more user equipment (UE) devices over multiple routes during IAB topology adaptation procedures, including in scenarios with and without a need to update security key parameters at UEs. The signaling and procedures, in both single connectivity and multi-connectivity scenarios, facilitate access UE devices maintaining user plane connectivity to their anchor serving cell, even when a mobile IAB node to which the UE devices are connected performs a mobility procedure (e.g., handover or SCG change).

    Abstract: Various aspects of the technology described herein are directed towards a generalized beam management framework in which beam management takes into account interference to steer a beam. Aspects comprise configuring a report request comprising a resource setting with channel state information-reference signal resource data and an associated report setting with parameter data corresponding to the one or more channel state information-reference signal resources. The report request is configured to instruct a user equipment device to include interference information when performing user equipment device beam management and reporting. Upon receiving the report request, the user equipment performs a beam measurement operation that includes interference information when generating the beam management report sent to the network device.

    Abstract: Systems and methods for computing channel state information in a 5G wireless communication system in 4G spectrum frequencies is described herein. A method as described herein includes determining, by network equipment comprising a processor, that a cell in which the network equipment operates is configured for coexistence between new radio signals and long term evolution signals based on a starting symbol location for non-user equipment specific control signaling received from the cell relative to a frame boundary; predicting, by the network equipment in response to the determining that the cell is configured for the coexistence, long term evolution resource overhead data associated with the long term evolution signals; and determining, by the network equipment, channel state information reference resources at least in part by removing the long term evolution resource overhead data from channel state information computation data.

    Abstract: The described technology is generally directed towards sharing a radio by multiple subscriber identities at a device. A time division multiplexing pattern at the device radio gives primary radio use to a first subscriber identity, while also providing time windows for radio use to a second subscriber identity. In response to a communication by the second subscriber identity, the time division multiplexing pattern can be changed to give the primary radio use to the second subscriber identity. Also, a radio resource control protocol can designate appropriate states for the different subscriber identities, designating the subscriber identity with primary radio use as connected, while the other subscriber identity is designated as inactive or idle.
