Abstract: Example grouping methods, apparatuses, and systems are provided. One example method includes receiving, by a central unit, a first interference intensity indication reported by at least one distributed unit. The central unit can then group the at least one distributed unit into at least one first distributed unit group based on the first interference intensity indication. The central unit can then send, to a controller, a distributed unit grouping indication and a second interference intensity indication that corresponds to the at least one first distributed unit group, where the distributed unit grouping indication is used to indicate the at least one first distributed unit group.

Abstract: A network entity is proposed for controlling the use, by a user equipment, of network slices of a communication network comprising a plurality of slice support areas. Each slice support area comprises at least one cell, and all cells of a given slice support area support the same network slices. A registration area for the registration of the user equipment with the communication network comprises at least one slice support area. The network entity is adapted to transmit, to the user equipment, slice support information for at least one slice support area of the communication network. The slice support information for a given slice support area indicates at least one network slice supported by the given slice support area and/or at least one network slice not supported by the given slice support area.
