摘要:
The invention relates to a wireless telecommunication system including at least one Base Station (BS) for communicating with at least one multihop Relay Node (RN) using a wireless link of a first type and with at least one local user equipment unit (UE) located within a range of the base station (BS) using at least one wireless link of a second type, wherein the wireless link of the first type is used to transmit a combined data flow encapsulating multiple individual data flows relating to different services and/or remote user equipment (UE) units. In order to enable a global fair scheduling, the base station (BS) is further configured to receive at least one local fairness parameter from the multihop relay node (RN), said local fairness parameter representing a fairness of the distribution of radio resources of the relay node (RN) over the individual data flows in the combined data flow and to execute a global fair scheduling procedure for determining a fair distribution of available radio resources of the base station (BS) over said at least one wireless link of the first type and said at least one wireless link of the second type, wherein the local fairness parameter is used as a parameter in said global fair scheduling procedure.

A method processes information to be sent via radio, according to which first bits represent a first number of N-tuples and second bits represent a second number of N-tuples. The first bits are to be sent using a first group of sub-bands of a frequency band, and the second bits are to be sent using a second group of sub-bands of the frequency band. A first modulation method is used for the first bits and a second modulation method is used for the second bits. The first bits are rearranged, forming M-tuples, and a symbol is formed from each M-tuple according to the first modulation method. The second bits are rearranged, forming P-tuples, and a symbol is formed from each P-tuple according to the second modulation method, and M≠P. A corresponding method is used for processing information received by radio. Base stations and mobile radio stations carry out the method.

In a method and/or an OFDM device for SC-FDMA data transmission, a sequence of input data is transformed by means of a discrete transformation as transformed data signals of coded and modulated data signals on first frequency channels into a first frequency space over a first number of frequencies. The transformed data signals are mapped on second frequency channels in a second frequency space with a larger second number of frequencies. The transformed data signals on the second frequency channels are inverse-transformed using an inverse transformation. Data inversely transformed in such a way are provided for transmission. The transformed data signals are mapped into a frequency range of the second frequency channels in such a way that a constant component of the transformed data signals is mapped centrally within the frequency range.

Embodiments of a Spectrum Access System (SAS) controller, Evolved Node-B (eNB) and methods for allocation of shared spectrum are disclosed herein. The SAS controller may receive an indicator that a group of channels in the shared spectrum are available for secondary usage. The SAS controller may allocate one or more channels in the group to eNBs for usage in one or more census tracts. The census tracts may include interior and exterior portions, in some cases. Fractional frequency reuse (FFR) techniques may be used in accordance with the interior and exterior portions of the census tracts for allocation of the channels. Channels may be allocated for Priority Access License (PAL) usage and/or General Authorized Access (GAA) usage, in some cases.

Method and device for data processing and communication system with such a device. The method and the device allow data processing via at least one channel. The method includes the following step of transmitting an idle pattern across the at least one channel when no information is conveyed. The idle pattern is created such that interference and/or crosstalk resulting from the idle pattern can be reduced at the receiving side.
