Abstract: Various embodiments disclosed herein provide for reduced overhead signaling when a user equipment device is being configured with multiple bandwidth parts for downlink transmission. When a user equipment device is being configured with multiple bandwidth parts (channels on an aggregate carrier), the signaling that indicates the codebook subset restriction bit map, rank restriction bit map, and beam restriction bit map needs to be repeated for each bandwidth part. Often however, the restriction bit maps are repeated in the bandwidth parts, and so overhead can be reduced by encoding a confirmation bit in each bandwidth part, such that if the confirmation bit is set to “1”, the user equipment device can know to apply the restriction bit map from the primary bandwidth part to the secondary bandwidth part, without having to encode the secondary bandwidth part restriction bit map.

Abstract: Various embodiments disclosed herein provide for a beam recovery when there has been a partial control channel failure. Transient obstructions, and other interference effects can cause the failure of a beam pair link which can comprise a transmit beam and a receive beam associated with respective antennas on a transmitter and receiver. A group of control channels (downlink control channels) (configured as a control resource set “CORESET”) on a group of beam pair links can be associated with a group of uplink control resources (Physical Uplink Control Channel resources). When a subset of the CORESET group fails, the user equipment (UE) device can find another PUCCH that is associated with a working CORESET to send an indication to the network about the failure. When the network receives the indication, the network can switch the failed CORESET to a new beam pair link.

Abstract: A broadband network gateway (BNG) controller is described that includes a network subscriber database (NSDB) and one or more core applications. The NSDB is configured to store vBNG instance information for one or more subscriber devices. The vBNG instance information specifies vBNG instances operable by one or more edge routers. The vBNG instances are configured to receive requests to access service provider services from the one or more subscriber devices and to selectively authenticate the one or more subscriber devices for network services based on authentication information included in the requests to access services provider services. The one or more core applications include a network instance and configuration manager (NICM). The NICM is configured to modify the vBNG instance information at the NSDB to include an additional vBNG instance and to output, to an edge router, an instruction to generate the additional vBNG instance at the edge router.

Abstract: Methods, apparatuses, systems, and devices are described for wireless communication. In one method, a control format indicator value for a frame may be received over a physical carrier in a shared spectrum. Based on the control format indicator value, a number of subframes of the frame to be used by a base station for downlink transmissions over the physical carrier may be determined. The control format indicator value may indicate an end of transmission, if data is to be transmitted during the frame, a number of subframes to be used for transmission, or whether the current subframe is the final subframe used for transmission. In some cases, a user equipment (UE) may use the control format indicator value to determine a sleep schedule. Further, ACK/NACK transmissions by a UE may be scheduled based on the control format indicator value.
