Integrated access and backhaul associated with NR

Random access may be provided for integrated access and backhaul (IAB) for New Radio (NR). A wireless transmit/receive unit may send (e.g., to a gNB) a preamble in a random access occasion (RO). One or more of the preamble or an RO resource partition of the RO may indicate a node type of the WTRU. T...

Zusammenfassung:	Random access may be provided for integrated access and backhaul (IAB) for New Radio (NR). A wireless transmit/receive unit may send (e.g., to a gNB) a preamble in a random access occasion (RO). One or more of the preamble or an RO resource partition of the RO may indicate a node type of the WTRU. The WTRU may receive (e.g., from the gNB) a physical downlink control channel (PDCCH) that indicates (e.g., includes) one or more random access responses (RARs). The WTRU may determine that the PDCCH indicates a WTRU RAR and an integrated access and backhaul (IAB) node RAR. If the sent node type is a WTRU node type, the WTRU may receive (e.g., from the gNB) the WTRU RAR at a first time and frequency location indicated by the PDCCH.
