Abstract: The embodiments herein relate to a method performed by a UE (800) capable for sidelink communications, for congestion control in a wireless telecommunications network, wherein the UE is allocated one or more resource pools, the method comprising: performing (701) CBR/CR measurements on said at least one resource pool to generate CBR/CR value(s); wherein the measurements are performed over a sensing window which is either pre-configured or adapted based on the QoS of at least one data packet or at least one service, and selecting (702) a resource pool or at least one resource within the resource pool based on a CBR/value and QoS requirements of the data packet or the service for transmission.

Abstract: An apparatus for a wireless communication system is configured to be connected to at least one UE via a sidelink for a sidelink communication with the one or more UEs. The apparatus is configured to obtain distance information representing a certain communication range or a certain distance around the apparatus, perform a communication with one or more UEs at or within the certain communication range or the certain distance at a first priority to meet a predefined QoS, and perform a communication with one or more UEs outside the certain communication range or the certain distance at a second priority, the first priority being higher than the second priority to meet a predefined QoS.

Abstract: A wireless communication system includes a plurality of user devices, UE. At least some of the UEs are configured for a sidelink communication. The wireless communication system is configured to provide resources for the sidelink communication among the UEs, the resources including a plurality of sets of resources or resource pools, RPs. The plurality of sets of resources or RPs includes 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 having 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 having a second QoS class, the first QoS class and the second QoS class being different.

Abstract: A mobile device being a member of a communication group and configured to communicate with one or more other members of the communication group and to exchange control information with the one or more other members, wherein the mobile device is configured to create an identification information and to transmit the identification information on a physical layer of the control information, wherein the identification information assigns the communication group.

Abstract: A method for centralized managing side link resources within a communication group, the communication group has a first mobile transceiver as group head and at least a second mobile transceiver as group member, wherein the first mobile transceiver is configured to distribute resources within the communication group, the method having: exchanging resource control information between the first and the second mobile transceiver, wherein the resource control information has at least an information regarding a timeslot and/or frequency slot of the resources and/or an information regarding a second portion of the resources so as to allocated the second portion to the second mobile transceiver.

Abstract: Embodiments provide a transceiver for a wireless communication system, wherein the transceiver is configured to communicate with at least one other transceiver of the wireless communication system using sidelink resource pools [e.g., mode 3 resource pool, mode 4 resource pool, shared resource pool, unshared resource pool or exceptional resource pool] of the wireless communication system, wherein the transceiver is configured to transmit a data packet on one of the sidelink resource pools of the wireless communication system to the other transceiver of the wireless communication system, wherein the transceiver is configured to, if a PPPR value associated with the data packet or with data contained in the data packet indicates a high reliability [of the data packet], to re-transmit the data packet at least on once on another sidelink resource pool of the sidelink resource pools of the wireless communication system.
