1. A user device (UE) for a wireless communication system, the wireless communication system comprising a plurality of user devices (UEs), the UE comprising:
one or more antennas or an antenna array having a plurality of antenna elements,
a signal processor, and
a transceiver,
wherein the UE is to communicate with one or more further UEs using a sidelink (SL),
wherein the UE is to operate in a Discontinuous Reception (DRX) mode,
wherein, when being out-of-coverage, the UE is to acquire one or more resources available for a transmission
from an assistance information message (AIM), received from the one or more of the further UEs during an ON duration of one or more DRX cycles, and/or
from an AIM, received from the one or more of the further UEs during a listening duration, and/or
by carrying out sensing in a set of sidelink resources or in a sidelink resource pool of the wireless communication system during a listening duration
wherein the listening duration comprises one or more of:
one listening duration preceding the ON duration, the one listening duration being consecutive with the ON duration or being offset from the ON duration by a certain time,
one listening duration following the ON duration, the one listening duration being consecutive with the ON duration or being offset from the ON duration by a certain time,
a plurality of listening durations preceding the ON duration, the respective listening durations being offset from each other by a certain time,
a plurality of listening durations following the ON duration, the respective listening durations being offset from each other by a certain time, and
wherein, during the listening duration, the UE is to carry out only sensing or receiving of AIMs and is not to transmit or decode any control information and/or data.
