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.

Communication techniques based on adaptive numerology

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.

Collaborative sidelink interference management with beam selection technique

The disclosure relates to user equipment (UE) (), comprising: a transceiver () configured to transceive radio resource control (RRC) messages between the UE () and a radio access network (RAN); and a radio resource controller () configured to activate an operation mode of the UE () responsive to processing a first sequence () of RRC messages when a non-congestion situation is indicated by the RAN, wherein the radio resource controller () is configured to activate the operation mode of the UE () responsive to processing a second sequence () 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 () of RRC messages is less than a latency for processing the first sequence () of RRC messages.
