US Patent 11184924 Multiple starting positions for uplink transmission on unlicensed spectrum

Systems and method for multiple uplink starting positions are disclosed. In some embodiments, a method of operating a wireless communication device includes identifying candidate starting positions for an uplink (UL) transmission in an unlicensed spectrum and selecting at least one starting position from among the candidate start positions based on autonomous UL starting points according to an outcome of a listen-before-talk (LBT) procedure performed with respect to the unlicensed spectrum and/or one or more fixed UL starting points signaled in a UL grant. In this way, a wireless communication device may improve throughput by using resources that would not have been available otherwise.
