Abstract

See full text

Coordination of listen before talk (LBT) structure in new radio (NR) unlicensed (NR-U) multi-channel access operations is disclosed. In one aspect, when a base station determines to access shared communication spectrum, it may transmit an LBT structure signal that identifies the current LBT structure. The base station would then attempt access to the shared spectrum according to the LBT structure. In another aspect, a coordination server is used to manage access to the shared spectrum. Each node desiring access registers with the coordination server, which provides access parameters for the accessing node to use that increases the likelihood of successful access. The accessing nodes will transmit the selected access configuration used to access the shared spectrum, wherein the access configuration is selected based on the access parameters.
