Abstract: The disclosure relates to recovering from a failure in a network. A flooding topology, represented by links between nodes in the network, is computed. Alternative connections for the links and the nodes on the flooding topology are also computed. A change in the flooding topology is detected, where the change indicates the failure in the network and results in a split of the flooding topology. A link state message is flooded to each of the nodes in a remaining part of the flooding topology and to the alternative connections, such that the link state message identifies the failure in the network. The failure in the network is resolved by connecting the split flooding topology using the remaining part of the flooding topology and the alternative connections as identified in the link state message.

Abstract: Systems, methods, and devices can be used to perform service-aware utilization of shared wireless resources. In various instances, a quality metric (e.g., a Bit Error Rate (BER)) of a shared wireless resource is determined. Requested services can be provided based at least partly on the quality metric and the type of services being requested. For example, when the quality metric exceeds a threshold and the requested services are for Quality of Service (QoS)-sensitive services (e.g., Guaranteed Bit Rate (GBR) services), the services can be provided at least partially via a licensed wireless resource. However, when the quality metric does not exceed the threshold, and/or the requested services are for non-QoS-sensitive services (e.g., non-GBR services), the services can be provided via the shared wireless resource.

Abstract: Certain aspects of the present disclosure relate to a method and apparatus for receiving a medium occupation and a resource block group (RBG) size from a gNB, wherein the radio block group size is based on a bandwidth part (BWP) configuration. In one example, UEs with smaller BWP have finer granularity in RBG size in terms of PRBs, while UEs with larger BWP may have a coarser granularity in RBG size in terms of PRBs. An additional guard band may be used if the gNB reserves some channels such that not all of the BW is occupied. For example, if the gNB reserves the 20 MHz channel, it may perform better by adding additional guard band on each side of the 20 MHz bandwidth to accommodate an adjacent channel leakage-power ratio (ACLR). Another aspect of the present disclosure relates to assigning a UE an interlace with equally spaced PRBs.
