2 . The wireless communication system of claim 1 , wherein the wireless communication system is configured to

use or implement the respective RPs for transmissions of messages on the sidelink comprising a certain QoS class in case one or more specific or predefined conditions are fulfilled, or.

not allow a transmission of messages on the sidelink comprising a certain QoS class in case one or more specific or predefined conditions are fulfilled.

3 . The wireless communication system of claim 2 , wherein the one or more specific or predefined conditions comprise:

a current or predicted QoS traffic of a certain class exceeds a configured or pre-configured threshold, and/or

one or more current or predicted network conditions for the sidelink exceed a configured or pre-configured threshold, and/or

one or more external or environmental conditions exist, and/or

a minimum needed communication range, the minimum needed communication range representing a communication range or a distance between the UEs needed to meet or fulfill a certain QoS

4 . The wireless communication system of claim 3 , wherein the one or more network conditions comprise a current or predicted sidelink traffic load and/or a congestion of the sidelink resources, and wherein the one or more specific or predefined conditions comprise that the traffic load and/or the congestion exceeds one or more configured thresholds or one or more pre-configured thresholds.

5 . The wireless communication system of claim 4 , wherein the traffic load is derived from the Channel Busy Ratio, CBR, and/or the Channel Occupancy Ratio, CR.

6 . The wireless communication system of claim 4 , wherein, in case of a congestion situation, certain QoS traffic, e.g., QoS classes with a priority lower than other QoS classes, are excluded from a transmission on the sidelink.

7 . The wireless communication system of claim 3 , wherein a value for the threshold is pre-configured or is set by a network operator.

8 . The wireless communication system of claim 1 , wherein the wireless communication system is configured to associate resources to the respective RPs dependent on a traffic distribution per QoS class or on a percentage of the QoS classes in the traffic.

9 . The wireless communication system of claim 1 , wherein the wireless communication system is configured to monitor the one or more specific or predefined conditions, e.g., a certain load condition or congestion condition, prior to preparing a transmission of a message comprising a certain QoS class, and to allow the transmission in case the one or more specific or predefined conditions are fulfilled.

10 . The wireless communication system of claim 1 , wherein the wireless communication system is configured to run one or more applications, each application configured to provide a service with a predefined or requested Quality-of-Service, QoS, class.

11 . The wireless communication system of claim 1 , wherein the wireless communication system is configured to map a QoS class to one or more of the RPs such that messages or packets with the first QoS class, which is higher than the second QoS class, use one or more predefined or prioritized RPs from the plurality of the RPs.

12 . The wireless communication system of claim 1 , wherein the wireless communication system is configured to map a QoS class to one of the plurality of the RPs such that the higher the QoS of an entity (e.g., a QoS bearer, a message or a packet) is the more RPs are allocated, so that a delay for accessing an RP may be minimized for the high QoS due to the high number of accessible RPs.

13 . The wireless communication system of claim 1 , wherein, to map the QoS classes to the RPs, the wireless communication system is configured to consider one or more of the following factors:

a current QoS class load/usage/distribution,

traffic conditions/congestion,

external/environmental conditions,

a minimum needed communication range, which may represent a communication range or a distance between the UEs needed to meet or fulfill a certain QoS.

14 . The wireless communication system of claim 1 ,

wherein the wireless communication system is configured to set a minimum needed communication range, which represents a communication range or a distance between the UEs needed to meet or fulfill a certain QoS, and

wherein dependent on the set minimum needed communication range associated with the respective QoS classes, the wireless communication system is configured to adjust the transmit power, e.g., by reducing/increasing a maximum or a minimum transmit power dependent on a current setting of the minimum requested communication range.

15 . A user device, UE, for a wireless communication system, the wireless communication system comprising one or more further user devices, UEs,

the UE is configured for a sidelink communication with one or more of the further user devices, UEs, using resources provided by the wireless communication system for the sidelink communication among the UEs, the resources comprising a plurality of sets of resources or resource pools, RPs, wherein the plurality of sets of resources or RPs comprises at least a first set of resources or RP and a second set of resources or RP,

wherein the UE is to use

the first set of resources or RP for a transmission over the sidelink of a first message comprising a first Quality-of-Service, QoS, class, and

the second set of resources or RP for a transmission over the sidelink of a second message comprising a second QoS class, the first QoS class and the second QoS class being different.

16 . A method for operating a wireless communication system comprising a plurality of user devices, UEs, wherein at least some of the UEs are configured for a sidelink communication, the method comprising:

providing resources for the sidelink communication among the UEs, the resources comprising a plurality of sets of resources or resource pools, RPs,

wherein the plurality of sets of resources or RPs comprises at least a first set of resources or RP and a second set of resources or RP, the first set of resources or RP to be used for a transmission over the sidelink of a first message comprising a first Quality-of-Service, QoS, class, and the second set of resources or RP to be used for a transmission over the sidelink of a second message comprising a second QoS class, the first QoS class and the second QoS class being different.
