A mobile device, in particular a vehicle, or an application server, includes a processor, which is configured to receive a notification from a network entity, in particular a base station. The notification includes information about available Quality of Service, QoS. The processor is configured to transmit a confirmation message to the network entity informing the network entity about an acceptance of the notified QoS. A network entity includes a network entity controller, which is configured to transmit a notification to a mobile device, in particular a vehicle, or an application server. The notification includes information about available Quality of Service, QoS. The network entity controller is configured to receive a confirmation message from the mobile device or the application server informing about an acceptance of the notified QoS.

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

Uplink synchronization may be achieved without adjusting for timing advance by using longer/larger cyclic prefix durations to compensate for differences in propagation delays, including the cell round-trip delays and environment based multipath delays. In this way, timing advance reference signaling may be omitted from the uplink transmissions. The cyclic prefix duration may be determined based on a characteristic of a base station's coverage area, such as a coverage area size or coverage area type. For example, a longer cyclic prefix length may be used when a base station has a larger coverage area than when the base station has a smaller coverage area. As another example, a different cyclic prefix length may be used for different coverage types. The method provided in this embodiment improves the capabilities of automatic driving and ADAS of electric vehicles. The method can be applied to vehicle networking, such as V2X, LTE-V, V2X, etc.

The invention relates to a base station, including a first and a second communication service, in a wireless communication network on the basis of a plurality of communication resources, the base station comprising: a processor configured to allocate a first physical downlink control channel associated with the first communication service to a first service-specific control region of the plurality of communication resources and a second physical downlink control channel associated with the second communication service to a second service-specific control region of the plurality of communication resources, wherein the first service-specific control region is associated with a first service-specific user data region of the plurality of communication resources and the second service-specific control region is associated with a second service-specific user data region; and a communication interface configured to transmit to a user equipment a radio frame comprising plurality of communication resources.

Base station and user equipment for a wireless communication network

An apparatus for processing data symbols in a multi-carrier transmitter, includes a transmit pulse shaper and a transmit sub-band filter. The transmit pulse shaper is adapted to filter a plurality of data pulses with respective transmit pulse shaping filters. Each of the data pulses is associated with a respective carrier of the multi-carrier communication system. The transmit sub-band filter is adapted to perform sub-band filtering of the pulse-shaped data pulses. The sub-band filter and at least one of the transmit pulse shaping filters are correlated. This correlation may be achieved by jointly designing the sub-band filter and the pulse shaping filter(s).

Filtered multi-carrier communications

A random access (RA) scheme exhibiting a non-isometric frame duration and a low latency. The RA and data messages have a duration with a different time unit and the time slot of the RA message is much shorter than the duration of one data frame. A specific signature, which is designed to be robust against the collisions, is transmitted during the RA request, the signature being either a unique sequence or a compressed signature. The user equipment device transmits the data message immediately after receiving its resource through a frame structure showing a time misalignment between adjacent data frames located in different or identical frequency sub-bands. A frequency guard band is inserted between its resource and an adjacent resource assigned to another user equipment device, the frequency guard band having an adaptive size according to the level of time misalignment and its impact on the distortion.

Message transmission through a random access scheme

The invention relates to a base station, comprising: a transceiver for multi-carrier radio transmission within a radio frequency band, the transceiver being adapted to receive service quality requests of a plurality of users requesting service from the base station; and a radio resource controller being adapted to allocate subcarriers of the multi-carrier radio transmission to the users and configure the subcarriers in the radio frequency band according to the service quality requests of the users.

The disclosure relates to a new Alamouti-based mapping scheme for use in a real field FBMC modulation system which can reduce FBMC-intrinsic interference and allows approaching optimal performance. The Alamouti-based mapping scheme proposed herein can be used for implementing space-time or space-frequency block codes (STBC/SFBC) codes. The proposed Alamouti-based mapping scheme suggests specific patterns to negate/invert signs of the modulation symbols of Alamouti pairs in the Alamouti mapping. By using these special patterns of sign negation, the FBMC-intrinsic interference can be reduced significantly so that it may become possible to use conventional Alamouti demapping/decoding procedures on the receiving side with an overall acceptable performance in real life systems.
