Latency reduction techniques for lte transmission in unlicensed spectrum

An apparatus for wireless communications using listen-before-talk (LBT) access for transmissions, comprising:

• a transceiver for communicating one or more wireless signals via one or more antennas;
• a memory configured to store instructions;
• and
• one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to:
• establish 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;
• receive ULL data for transmission;
• map the ULL data for transmission to the dedicated ULL data bearer based at least on the LBT access rules;
• and
• perform channel selection in the portion of the unlicensed frequency spectrum using the LBT access rules to identify a channel to use for transmission.

• means for receiving ULL data for transmission;
• means for mapping the ULL data for transmission to the dedicated ULL data bearer based at least on the LBT access rules;
• and
• means for performing channel selection in the portion of the unlicensed frequency spectrum using the LBT access rules to identify a channel to use for transmission.

A non-transitory computer-readable medium storing computer executable code for wireless communications at a wireless communication device using listen-before-talk (LBT) access for transmissions, the code comprising:

• code for establishing, by the 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;
• code for receiving, at the wireless communication device, ULL data for transmission;
• code for 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
• code for 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.
