Abstract: A UE receives a request from a base station to initiate a random access procedure in a connected state. When a first bandwidth part does not contain any random access resource that is available, the UE: switches to a second bandwidth part that contains one or more random access resources that are available and transmits a preamble sequence at a first random access resource selected from the one or more random access resources that are available. When the first bandwidth part contains the one or more random access resources that are available, the UE transmits the preamble sequence at a second random access resource selected from the one or more random access resources that are available. The second random access resource is at least a second time duration subsequent to the request. The second time duration is shorter than the first time duration.

Abstract: Methods, apparatuses, and systems for improving utilization of a communications system (e.g., a satellite communications system) are provided, using delayed reliability techniques as part of a multicast transport protocol.

Abstract: In one embodiment, a network device (e.g., a RPL router) executes fast local RPL recovery in a low power and lossy network (LLN). The network device, in response to becoming an orphan in a directed acyclic graph (DAG) topology, can utilize the data plane to maintain at least some data traffic by randomly forwarding the data traffic to identified neighbor devices, while eliminating children from the list of forwarders and by finding successors that can be used for re-parenting. Hence, when a RPL network device having lost its last feasible parent can avoid data loss and accelerate a re-parenting process using local repair in the data plane instead of the control plane of the routing protocol used to establish the DAG topology.
