The present disclosure relates to a technique for steering a Random Access Channel (RACH) a wireless communication network supporting a set of network slices. More specifically, the technique involves generating, at a RAN node, RACH steering information for the set of network slices. The RACH steering information comprises an indication for a UE to select one of available RACH configurations with a RACH configuration-specific probability. In one embodiment, the RACH steering information may be defined based on at least one network slice-specific RACH policy or at least one network slice-specific resource sharing quota provided from a network management entity to the RAN node. In another embodiment, the RAN node may generate RACH steering information based on locally available information about the set of network slices. Once the RACH steering information is generated, the RAN node transmits it to the UE. By using the RACH steering information, it is possible to dynamically adjust a RACH load among multiple network slice-specific RACH configurations and common RACH configurations, thereby efficiently balancing the RACH load (i.e., RACH utilization rate) across the set of network slices.
