Abstract: A first transceiver for a wireless communication system according to an embodiment is to determine information on an occupancy of a transmission channel. Moreover, the first transceiver is to transmit the information on the occupancy of the transmission channel to a second transceiver. Furthermore, the first transceiver is to determine the information on the occupancy of the transmission channel and to transmit the information on the occupancy of the transmission channel to the second transceiver without having received from the second transceiver a ready-to-transmit message with which the second transceiver would inform the first transceiver that the second transceiver intends to transmit user data to the first transceiver.

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. The UE identifies a sidelink control message for the UE by blind decoding, and decodes the sidelink control message for the UE to derive control information embedded the sidelink control message. The UE is pre-configured or configured by a network or a base-station with a sidelink, SL, search space, e.g., a SL-CORESET or SL control channel occasions, in the sidelink resources. The sidelink search space includes one or more search occasions where the UE is to perform the blind decoding on the 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.

According to exemplary embodiments, there is provided a retransmission counter placed or implemented at the UE and/or the gNB which is configured to count every failing data packet (i.e., the receiver(s)/transmitters is/are informed via the NACK messages or the NACK timers). There is also provided a retransmission assignment indicator message configured to include, fully or partially: the content of said counter and the content or the structure of the CGB (Code Block Group), e.g., either all CBGs are retransmission versions or part of the CGBs are retransmission versions.

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.

Abstract: An apparatus, for wideband communication with one or more transceivers in a wireless communication system using one or more subbands of a predefined wideband, is configured to perform initial Listen-Before-Talk, LBT, for each subband of the predefined wideband so as to determine from the predefined wideband one or more non-occupied subbands on which the wideband communication is allowed during a certain transmission time, and during the certain transmission time, transmit to and/or receive from the transceiver using the non-occupied subbands. During the certain transmission time and in case the initial LBT indicted that one or more of the subbands are occupied, the apparatus is configured to perform a further LBT for the one or more occupied subbands so as to determine one or more of the initially occupied subbands being no longer occupied, and transmit to and/or receive from the transceiver using, in addition to the initially non-occupied subbands, the one or more no longer occupied subbands.
