Enhanced preamble waveform for coexistence

Methods, systems, and devices are described for wireless communication at a device. A Long Term Evolution Unlicensed (LTE-U) device may transmit an enhanced preamble that may be understood by Wireless Local Area Network (WLAN) devices, in addition to conveying a characteristic that is detectable by receiving LTE-U devices. The transmitting LTE-U device may generate the enhanced preamble by generating a first training field and a second training field. The characteristic that is detectable by receiving LTE-U devices may be a phase shift between the first and second training fields. Additionally or alternatively, the characteristic may be a sequence or tone mapping of the first or second training field. In some cases, the transmitting LTE-U device may introduce a third training field to the preamble which serves as the characteristic.

Multiplexing logical channels with different channel access priority class in new radio unlicensed

A method of multiplexing logical channels (LCHs) in configured grants (CG) to enable faster transmission of high priority data in 5G New Radio-Unlicensed (NR-U) is proposed. Two options of imposing a CAPC-based restriction rule on multiplexing a low priority LCH with a high priority LCH are provided. In a first option, a threshold CAPC value is configured via RRC signaling. Data belonging to LCH having a priority lower than the CAPC threshold is not allowed to be multiplexed with data belonging to LCH having a priority higher than the CAPC threshold. In a second option, each CAPC has a flag indicating if the CPAC can have reduced priority via RRC signaling. If the flag is set for the CAPC, then data belonging to LCH assigned with the CAPC cannot be multiplexed with data belonging to lower priority LCHs.
