  • Publication number: 20220191926
    Abstract: Various procedures associated with autonomous uplink (AUL) are disclosed. In order to address the mismatch between listen before talk (LBT) and AUL bandwidth a fractional sensing channel is defined less than 20 MHz. Accordingly, a user equipment (UE) may use the fractional sensing channel to perform LBT only on the resources allocated for AUL. Contention window update may further be modified for transmissions spanning multiple transmission opportunities (TxOPs). A contention window update may occur over all transmission channels considering full acknowledgement information of each TxOP, a percentage of acknowledgement information weighted on the number of channels, a percentage of acknowledgement information weighted on the ratio of resources on each channel, or by selecting a primary channel of the multiple channels for the contention window update.

  • Publication number: 20220191921
    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for increasing the chances that a high reliability packet scheduled to be transmitted in a shared radio frequency spectrum is received by a receiving device. In one example, a wireless device (e.g., a base station or a user equipment (UE)) may duplicate a packet at a packet data convergence protocol (PDCP) layer for transmission on multiple listen before talk (LBT) subchannels of a carrier to improve reliability. In another example, a wireless device may duplicate a packet at a physical (PHY) layer for transmission on multiple LBT subchannels of a carrier to improve reliability, or the wireless device may encode and map the packet to multiple LBT subchannels of a carrier for transmission on the multiple LBT subchannels to improve reliability.
