Claim of US Patent No. 10,342,044

1. A method of wireless communication in a wireless communication system including listen-before-talk (LBT) access for transmissions, comprising:establishing, by a wireless communication device, a dedicated ultra-low latency (ULL) data bearer having LBT access rules for accessing at least a portion of an unlicensed frequency spectrum served by the wireless communication system, wherein the LBT access rules allow channel access with a faster access priority than control and signal traffic;
receiving, at the wireless communication device, ULL data for transmission;
mapping, by the wireless communication device, the ULL data for transmission to the dedicated ULL data bearer based at least on the LBT access rules; and
performing, by the wireless communication device, channel selection in the portion of the unlicensed frequency spectrum using the LBT access rules to identify a channel to use for transmission.
