Abstract: A synergetic communication method for relay node identification (ID) acquisition is proposed. The network node may generate a configuration based on the relay node information from a user equipment (UE) to configure the relay node ID for the relay node in an aggregated group. The network node may schedule the operations of the devices of the aggregated group based on the configuration. The UE may detect the relay node and assign the relay node ID configured by the network node to the relay node in the aggregated group. Therefore, when the relay node in the aggregated group cannot directly obtain the relay node ID from the network node, the UE can assist of obtaining the relay node ID from the network node and assigning the relay node ID to the relay node in the aggregated group.

Abstract: A synergetic communication method for capability reporting in relay communications is proposed. A user equipment (UE) may detect the relay node(s). In an event that a trigger condition is triggered, the UE may transmit the capability report associated with the detected relay node to the network node. The network node may generate the resource configuration based on the capability report from the UE. Therefore, the network node is able to obtain the capability information of the relay node even if the relay node has limited capability, e.g., the relay node is a layer 0 (L0) relay node or a layer 1 (L1) relay node.
