Abstract

A radio device may receive network assistance information relating to uplink channel access procedures, such as channel access types and related listen-before-talk techniques, via layer one signaling or higher layer signaling. For example, information may be provided via DCI, MAC CE, or RRC messaging, e.g,, received in a CORESET preceding the configured PRACH resources. Access procedures may be random access procedures, and may include indication via R.AR messaging. Access procedures may be triggered by a radio access point message, such as a PDCCH order or a handover request.
