Duplication and RLC operation in new radio access technology

For a source stream of input data where FEC scheme(s) have been used to create a repair stream, transmitting by a network node packet(s) comprising data of the source stream or the repair stream packaged as at least part of PDU(s). An ARQ or HARQ process is applied to the PDU(s). The network node receives feedback information as part of the process corresponding to the PDU(s), including positive ACK/NACK response for the PDUs. The retransmissions of the negatively acknowledged PDU(s) are controlled when the FEC scheme is known not to be able to compensate for loss(e)s of packet(s) contained in the PDU(s) indicated as being negatively acknowledged. A UE receives packet(s), determines loss(es), and, in response to a determination the FEC scheme is known to be able to recover from the loss(es), sends at least one ACK for any lost packets that correspond to the one or more loss(es).

Embodiments of the present disclosure relate to a device, a method, an apparatus and a computer readable storage medium for bandwidth part (BWP) switching. In example embodiments, a method is provided. The method comprises determining, at a terminal device, whether continuous Listen-Before-Talk (LBT) failures occur on a first bandwidth part (BWP), the terminal device operating on the first BWP. The method further comprises in response to the continuous LBT failures occurring on the first BWP, switching to a second BWP different from the first BWP. Instead of triggering a re-establishment procedure once continuous LBT failures are detected, switching to another BWP on different LBT sub-channels can be much more efficient than going through the whole re-establishment and reconfiguration procedures.
