Abstract: A user device, UE, for a wireless communication system, is connected to one or more further UEs in the wireless communication system for a sidelink communication with the one or more further UEs. The sidelink communication include one or more sidelink control messages, e.g., a Sidelink Control Information, SCI, to be transmitted on sidelink resources.

Abstract: An apparatus for a wireless communication system uses a plurality of frequency bands for a communication with one or more network entities. The apparatus receives a transport block, TB, which is split into a plurality of code block groups, CBGs, comprising one or more code blocks, CBs, confined to one of the plurality of frequency bands. The apparatus provides or predicts a feedback for each CBG indicating one or more of a successful receipt, a non-successful receipt, no need for redundancy and a need for some redundancy. The apparatus compresses the feedbacks for each CBG into a compressed feedback based on an interference pattern on one or more of the frequency bands which is detectable at the apparatus and the transmitter or the one or more network entities, e.g. Listen-before-Talk, LBT, failure, and to transmit to the one or more of the network entities the compressed feedback.

Abstract: A user device, UE, for a wireless communication system is served by a base station and uses one or more frequency bands for a communication with one or more entities, e.g., other UE(s) or other gNB(s), in the wireless communication system. Some or all of the plurality of frequency bands are unlicensed frequency bands on which a communication is allowed for a certain transmission time (COT) responsive to a successful channel access procedure e.g. Listen-Before-Talk, LBT. The UE is configured, e.g., using an RRC signaling, with one or more configured grant, CG, configurations so as to allow the UE to perform one or more CG transmissions. Responsive to detecting a COT and a potential collision of a CG transmission with the COT, e.g. the COT of another entity, e.g., other UE(s) or other gNB(s), in the wireless communication system, the UE deactivates or backs off the CG transmission.
