A user device 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 in the wireless communication system. The frequency bands include CORESETs, each including one or more search spaces carrying control information for the UE. The UE groups some or all of the CORESETs into respective CORESET groups, or some or all of the search spaces into respective search space groups. A CORESET group includes some or all CORESETs within a certain time window, and a search space group includes some or all search spaces within the certain time window. The grouping is responsive to one or more group IDs the UE is configured with, each group ID pointing to or indicating a CORESET group or a search space group, and/or determining CORESETs or search spaces to be within the same time window.

Control resource set grouping

The embodiments herein relate to a method performed by UE, a UE, a network node or gNB and a method performed by the gNB for handling retransmissions in a wireless telecommunications system and resolving misalignment between the UE and the gNB. 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.

Methods and apparatuses for handling retransmissions in a wireless telecommunications system

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.
