Abstract: Embodiments include methods, performed by a network node, for configuring a physical random-access channel (PRACH) of a cell in a time-division-duplexed (TDD) radio access network (RAN). The methods include determining an increase in a level of remote interference in the cell and, in response to determining the increase, selecting a first PRACH configuration from a first subset of available PRACH configurations. The first subset of available PRACH configurations can be more robust against remote interference than a second subset of the available PRACH configurations, and the first subset can be exclusive of the second subset. The methods also include transmitting, to one or more user equipment (UEs) first information indicating that the first PRACH configuration should be used for accessing the cell via the PRACH. Embodiments also include complementary methods performed by UEs, as well as network nodes and UEs configured to perform such methods.

Abstract: The present disclosure relates generally to the field of drill tool identification. More particularly, it relates to a drill tool and a system configured for such drill tool identification. The drill tool includes a machined marking on a perimeter surface, wherein the machined marking is positioned on a segment of the perimeter surface and includes a matrix of indentations having predetermined column and row positions to convey an identity of the drill tool, and wherein the machined marking is optically readable from a plurality of single directions when mounted in a drill rig.
