Uplink (UL) transmission with flexible starting positions for new radio-unlicensed (NR-U)

Abstract:

Wireless communications systems and methods related to uplink (UL) communications in a wireless network are provided. In one embodiment, a first wireless communication device receives a transmission grant indicating a transmission period. The first wireless communication device selects a starting location for transmitting a communication signal from among a plurality of starting locations within the transmission period. The first wireless communication device transmits the communication signal during the transmission period based on the selected starting location. In one embodiment, a first wireless communication device transmits, to a second wireless communication device, a transmission grant indicating a transmission period. The first wireless communication device monitors for a communication signal from the second wireless communication device in the transmission period. The first wireless communication device identifies, upon detection of the communication signal, a starting location of the communication signal from among a plurality of starting locations within the transmission period.
