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.

The UE monitors one or more paging occasions, POs, for a paging signal directed to the UE by the base station network and receives, ahead of an upcoming PO, a paging early indication, PEI, the PEI indicating whether the UE is to expect a paging signal in the upcoming PO. Paging early indication, PEI, enhancements, for example for improving a power saving behavior of a user device, are described.

Abstract: A user device, UE, for a wireless communication network is described. The he UE performs measurements of one or more reference signals received from a network entity of the wireless communication network, each reference signal being associated with a TCI state. For transmitting or receiving a transmission associated with a certain TCI state, the UE uses one or more parameters obtained by the measurement of the reference signal being associated with the certain TCI state of the transmission. Responsive to a certain event, the UE resets parameters obtained by a measurement associated with the TCI state of at least one of the one or more reference signals.

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.
