2 . User equipment according to claim 1 , wherein said part is overlapping with a LTE resource pool or a resource pool of another communication network.

3 . User equipment according to claim 1 , wherein the adaption technique comprises one or the following techniques:
adapting the resource reselection counter; adapting resource reservation periodicity; deactivating certain resources and/or resources belonging to a certain periodicity, and/or
wherein adaption technique and/or restricting as part of adaption technique and/or reselecting as part of adaption technique is performed dependent on one or more of the following criteria:
Presence/absence of LTE sensing information,
Number of negative HARQ feedback received,
Reception of collision indicators,
Resource pool configurations received from a gNB,
Reception of IUC messages that take into account LTE sensing information.

4 . User equipment according to claim 1 , wherein the adaption technique comprises adapting or lowering resource reselection counter which is used to trigger a resource reselection for a periodic transmission; and/or
wherein adapting and/or lowering comprises changing a range from which random numbers for the resource reselection counter are drawn; and/or wherein the range parameter of the transmission is dependent on the resource reservation interval used for the periodic transmission.

5 . User equipment according to claim 1 , wherein the adaption technique comprises adapting the resource reservation periodicities (e.g. that are configured to be used in the NR resource pool or the shared portion of the NR resource pool) to LTE periodicities (e.g. pre-configured for the LTE resource pool) or determining LTE periodicities (e.g. by sensing the currently used periodicities for LTE transmissions) and adapting resource reservation periodicity dependent on determined LTE periodicity.

6 . User equipment according to claim 1 , wherein the adaption technique comprises adapting resource reservation periodicity to non-LTE periodicity or to only certain periodicities not used for LTE, and/or
wherein the adaption technique comprises deactivating periodic transmission or deactivating aperiodic transmission, and/or wherein adaption technique and/or restricting as part of adaption technique and/or reselecting as part of adaption technique is performed dependent on LTE sensing or LTE RSRP sensing.

8 . User equipment according to claim 1 , wherein adaption technique and/or restricting as part of adaption technique and/or reselecting as part of adaption technique is performed dependent on a determined PSFCH feedback.

9 . User equipment according to claim 1 , wherein adaption techniques and/or restricting as part of adaption technique and/or reselecting as part of adaption technique is performed dependent on feedback from another UE (e.g. detecting a collision or failed decoding), or on information received from another UE, and/or
wherein adaption techniques and/or restricting as part of adaption technique and/or reselecting as part of adaption technique is performed dependent on receiving a collision indication or IUC message from another UE.

10 . User equipment according to claim 1 , wherein adaption technique is performed based on or taking into account information out of a pre-configuration or information from a gNB (e.g DCI, MAC or RRC signaling).

11 . User equipment according to claim 1 , wherein adaption technique is based on LTE sensing information acquired by another transceiver unit of the user equipment or acquired by another UE or acquired by another network entity.
