Claim 0:
1. A method performed by a transmitter configured for use in a wireless communication system, the method comprising:
obtaining data packets at a higher layer of a protocol stack implemented by the transmitter;
duplicating each data packet at the higher layer to obtain duplicates of each data packet;
transmitting the duplicates of each data packet on different respective channels from the higher layer to a lower layer of the protocol stack;
generating different transport blocks to include data from the different respective channels, such that the duplicates of each data packet are conveyed by different transport blocks; and
for each transport block, transmitting or not transmitting at least a part of the transport block within at least a part of a different respective transmission opportunity on a link to a receiver using unlicensed frequency spectrum, depending on whether or not a channel sensing procedure indicates the unlicensed frequency spectrum is clear during that at least part of the transmission opportunity;
wherein the transmitter or the receiver is a user equipment (UE);
wherein the link is or corresponds to a single bandwidth part, channel, or sub-band where the UE has only one single connection to the wireless communication system available.
