Signaling systems and methods used for secondary link relay communication.

Abstract

The systems and methods for transmitting or exchanging signaling used for wireless relay communication are revealed. According to one scheme, the method implemented by the first node is revealed. This method includes: collecting, from the wireless communication device, the first indicator information indicating the wireless communication device layer supporting relay communication related to the wireless communication device; transmitting, to the second network node, the second indicator information generated based on the first indicator information; and collecting, from the second network node, the third indicator information indicating whether the wireless communication device is permitted to perform relay communication.
