Section: 6.9 Connectivity models 6.9.2.1 General
Content: The 5G system shall support the relaying of traffic between a remote UE and a gNB using one or more relay UEs. The 5G system shall support same traffic flow of a remote UE to be relayed via different indirect network connection paths. The 5G system shall support different traffic flows of a remote UE to be relayed via different indirect network connection paths. The connection between a remote UE and a relay UE shall be able to use 3GPP RAT or non-3GPP RAT and use licensed or unlicensed band. The connection between a remote UE and a relay UE shall be able to use fixed broadband technology. The 5G system shall support indirect network connection mode in a VPLMN when a remote UE and a relay UE subscribe to different PLMNs and both PLMNs have a roaming agreement with the VPLMN. The 5G system shall be able to support a UE using simultaneous indirect and direct network connection mode. The network operator shall be able to define the maximum number of hops supported in their networks when using relay UEs. The 5G system shall be able to manage communication between a remote UE and the 5G network across multi-path indirect network connections.
