Abstract: Solutions are disclosed that provide for user equipment (UE) initiated intelligent adaptive measurement gaps. A stationary (non-moving) UE has a reduced likelihood of requiring a handover (HO) to a neighboring cell and thus, unless the serving cell has degraded or interference has increased, a reduced urgency of measuring signal reception from neighboring cells. A UE receives a radio resource control (RRC) message specifying a measurement gap repetition period (MGRP) from a wireless network, and upon determining that it has been stationary (within some range) for a threshold length of time, skips a measurement gap specified by the MGRP. In some examples, the UE uses changes (or lack thereof) in the uplink timing advance to ascertain whether it has moved or been stationary. In some examples, the MGRP is indicated as having one of four values: 20 milliseconds (ms), 40 ms, 80 ms, and 160 ms.

Abstract: A method and system for finding a preferred tour of a navigation map for a robotic device. An A*algorithm is used to generate a super adjacency list of the number of turns in shortest paths between pairs of map vertices and identifying preferred directions of each vertex to assign pheromone and heuristic values to vertices. Using a modified Ant Colony Optimization (ACO) algorithm paths through the map are traced by artificial “ants” to solve the tour problem using the heuristic and pheromone values until all vertices have been visited. The total distance and number of turns are calculated from the super adjacency list. A best fraction of paths based on distance and number of turns may be selected, the pheromone and heuristic values may be updated for vertices on those paths. A best path through the navigation map may be selected based on all iterations and provided as an output.
