Abstract: The disclosure relates to user equipment (UE) (700), comprising: a transceiver (701) configured to transceive radio resource control (RRC) messages between the UE (700) and a radio access network (RAN); and a radio resource controller (702) configured to activate an operation mode of the UE (700) responsive to processing a first sequence (328) of RRC messages when a non-congestion situation is indicated by the RAN, wherein the radio resource controller (702) is configured to activate the operation mode of the UE (700) responsive to processing a second sequence (525, 625) of RRC messages when a special situation, in particular a congestion situation or a power saving situation to reduce the energy consumption, is indicated by the RAN, wherein a latency for processing the second sequence (525, 625) of RRC messages is less than a latency for processing the first sequence (328) of RRC messages.

Abstract: A mobile communication device has a receiver configured to receive a radio signal over a radio channel. The radio signal has a predetermined pilot preamble. The mobile communication device has a processor configured to determine mobility information, in particular a Doppler and/or a Delay Spread, based on the pilot preamble. The processor is further configured to signal the mobility information to a second communication device. A base station is also provided, having: a receiver configured to receive mobility information, in particular a Doppler and/or a Delay Spread, signaled by a mobile communication device; and a processor, configured to select a numerology based on the mobility information and to generate a radio signal for transmission to the communication device based on the numerology.

Abstract: A network controller for controlling beamformed signals that are transmitted by a cluster of devices. The network controller is configured to allocate, to each device, a beam index that determines a respective beam reference signal structure to use when transmitting beamformed signals over a sidelink between the devices, and to make the allocation in such a way as to minimise interference between the beamformed signals.
