Abstract: A method and apparatus may include receiving, by a user equipment from a first access point which supports a first radio access technology, a radio-resource-control (RRC) reconfiguration message including an RRC configuration information of a second access point, after an initiation of a slave RRC at the second access point has been determined. The second access point supports a second radio access technology, and performing, by the user equipment, a random access procedure with the second access point based on the RRC reconfiguration message. The user equipment is configured to have an RRC connection with the first access point and the first access point is a master node.

Abstract: A multi-section optical modulator and related method are disclosed wherein two waveguide arms traverse a plurality of successive modulating sections. A differential drive signal is applied separately to each waveguide arm of each modulating sections in synchronism with the transmission of light along the waveguide arms, effecting a dual differential driving of each section. By suitably selecting the number of modulating sections and the section length, a high modulation bandwidth and a high modulation efficiency may be achieved simultaneously for a given peak-to-peak voltage swing of the drive signal.

Abstract: A method and apparatus may include transmitting a measurement split request to a network node. The measurement split request designates a first measurement layer and a second measurement layer. The first measurement layer corresponds to a measurement configuration for the apparatus. The second measurement layer corresponds to a measurement configuration for the network node. The method may also include receiving an acknowledgement that the measurement split request is accepted by the network node. The method may also include transmitting the measurement configuration for the apparatus and the measurement configuration for the network node to a user equipment.

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.
