Abstract: For a communication between two UEs that passes through a network node, a total number of transmission attempts for a same set of data is divided between first and second data transmission attempt(s). The first data transmission attempt(s) are allowed to be performed from a first one of the two UEs toward the network node. The second data transmission attempt(s) are allowed to be performed from the network node or from a second network node toward a second one of the two UEs. Performance of the first and second data transmission attempt(s) is coordinated based on the division to cause communication of the set of data from the first UE to the second UE. A single network node may perform the first and second data transmission attempts, or a first network node performs the first data transmission attempts while a second network node performs the second data transmission attempts.

Abstract: Measures are provided for management of RRC for D2D communication. Such measures include setting a connected state of RRC for device(s) of a pair of devices. For the devices(s), both a D2D communication service between the pair of devices and a core network communication service between the device(s) and a core network entity are active. The setting enables radio resource management for the device(s) for the D2D communication service and the core network communication service. Termination of the core network communication service is detected for the device(s). A connection towards the core network entity is reconfigured for disabling the core network communication service of the device(s). The connected state of RRC is maintained for the devices(s) of the pair of devices, for which the device(s) only the device-to-device communication service is active. The maintaining enables radio resource management for the device(s) for the D2D communication service.

Abstract: A method and apparatus may include determining that a triggering has occurred. The triggering corresponds to a triggering of a formation of a multiple-input and multiple-output arrangement. The multiple-input and multiple-output arrangement comprises a grouping of user antennas and an antenna of the apparatus, and the apparatus is located at an existing infrastructure. The method may also include receiving data traffic information. The data traffic information comprises information that indicates an amount of data traffic that is requested by users of the user antennas. The method may also include forming the multiple-input and multiple-output arrangement based on the received data traffic information.

Abstract: An example method includes generating, by a first user device, a first number representing a contention resolution priority for the first user device contending for at least one first resource over a first data period for transmitting a packet of data in a device-to-device (D2D) wireless network, determining if a second device, in the D2D wireless network, is contending for resources overlapping with the at least one first resource of the first data period, if the second device is contending for resources overlapping with the at least one first resource of the first data period, determining if a second number representing a contention resolution priority for the second user device is greater than the first number, and if the second number is greater than the first number, inhibiting the first user device from communicating using the at least one first resource of the first data period.
